Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.

Reference in the specification to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly understand that the embodiments described herein may be combined with other embodiments.

The method for testing the expansion module interface of the intelligent terminal can be applied to an application environment shown in fig. 1. The test control device is provided with a device for testing an expansion module interface of the intelligent terminal (the device can be simply called a test control device), and the test control device can perform test interaction with the intelligent terminal through the test interface. The method for testing the expansion module interface of the intelligent terminal provided by the application can comprise the following steps: after an expansion module interface of the intelligent terminal is connected with a test interface, the test control equipment configures a first expansion module for the test interface, generates a first link negotiation response corresponding to the first expansion module, and sends the first link negotiation response to the intelligent terminal through the test interface; the intelligent terminal responds to the first link negotiation response and returns first test data through an expansion module interface; after receiving the first test data, the test control device reconfigures a second expansion module for the test interface and generates a second link negotiation response corresponding to the second expansion module, wherein the expansion function type of the second expansion module is different from that of the first expansion module; the intelligent terminal responds to the second link negotiation response and returns second test data through the expansion module interface; the test control device determines a test interface for the expansion module interface according to the first test data and the second test data.

The intelligent terminal is provided with one or at least two expansion module interfaces, the physical structures of the expansion module interfaces are consistent, and when the expansion module interfaces of the intelligent terminal are tested (whether the expansion interfaces support corresponding expansion functions or not is tested), the expansion module interfaces need to be spliced with the test interfaces, so that the physical structures of the test interfaces are matched with the physical interfaces of the expansion modules; because the physical interfaces of the expansion module interfaces of the intelligent terminal are consistent, when the number of the expansion module interfaces is at least two, the number of the test interfaces can be corresponding to the number of the expansion module interfaces, and when the expansion module interfaces and the test interfaces are plugged, one of the test interfaces can be plugged with any expansion module interface.

When testing the expansion module interface of the intelligent terminal conventionally, different test interfaces correspond to different expansion functions, that is, if the expansion module interface needs to be tested to realize multiple expansion functions, the expansion module interface needs to be respectively plugged with multiple test interfaces, so that the test efficiency is low.

Based on this, in order to improve the testing efficiency of the expansion module interface of the intelligent terminal, the present application provides a method for testing the expansion module interface of the intelligent terminal, as shown in fig. 2, and the method is applied to the test control device in fig. 1 for illustration, and includes the following steps:

Step S202, a first expansion module is configured for the test interface, and a first link negotiation response corresponding to the first expansion module is generated.

The test control device can configure the test interface with the expansion modules so that the test interface corresponds to the different expansion modules; the test control device configures an expansion module for the test interface, which can be understood as: the test interface is controlled to transmit data related to the configured expansion module, for example, the test control device configures the expansion module of the test interface as an RS485 meter reading module, which is equivalent to that the test control device controls the test interface to transmit data related to the RS485 meter reading module (wherein the data related to the RS485 meter reading module can be the function specification of the RS485 meter reading module or the RS485 meter reading data).

The test control equipment can pre-store at least two expansion modules with different expansion function types, such as an RS485 meter reading module, a start acquisition module, an ammeter control module and the like, and further, the expansion modules with different expansion function types can correspond to different identifications; when the test control device configures the first expansion module for the test interface, any one expansion module can be selected from at least two expansion modules with different expansion function types stored in advance and used as the first expansion module, and then a first link negotiation response is generated according to the identification of the first expansion module.

The expansion module interface connected to the test interface may be understood as an expansion module interface to be tested (in the following description, reference to an expansion module interface may refer to an expansion module interface to be tested).

Step S204, a first link negotiation response is sent to the intelligent terminal through the test interface; the first link negotiation response is used for indicating the intelligent terminal to return first test data through the expansion module interface; the expansion module interface is connected with the test interface.

In this step, after generating the first link negotiation response corresponding to the first extension module, the test control device may send the first link negotiation response to the test interface; the test interface transmits the first link negotiation response to the connected expansion module interface so that the intelligent terminal receives the first link negotiation response; after receiving the first link negotiation response, the intelligent terminal analyzes the first link negotiation response to obtain an identifier of a first expansion module, determines that an expansion module configured by test control equipment for a test interface is the first expansion module according to the identifier of the first expansion module, processes a corresponding expansion function according to the determined first expansion module to obtain first test data, transmits the first test data to the test interface through the expansion module interface, and returns the first test data to the test control equipment through the test interface.

In order to further improve the test efficiency, before the test control device sends the first link negotiation response to the intelligent terminal through the test interface, the test control device may further send a first extended function protocol corresponding to the first extended module to the intelligent terminal, and after receiving the first link negotiation response, the intelligent terminal may perform corresponding extended function processing according to the first extended function protocol, so as to obtain first test data.

Step S206, after receiving the first test data, reconfiguring a second expansion module for the test interface and generating a second link negotiation response corresponding to the second expansion module; wherein the type of the extended function of the second extended module is different from the type of the extended function of the first extended module; the second link negotiation response is used for indicating the intelligent terminal to return second test data through the expansion module interface.

In the step, after receiving first test data transmitted by a test interface, test control equipment selects a second expansion module from at least two expansion modules with different expansion function types stored in advance, wherein the expansion function type of the second expansion module is different from that of the first expansion module, and reconfigures the second expansion module for the test interface; after the configuration is completed, the test control equipment generates a second link negotiation response according to the identification of the second expansion module, and transmits the second link negotiation response to an expansion module interface of the intelligent terminal through the test interface; after receiving the second link negotiation response, the intelligent terminal analyzes the second link negotiation response to obtain the identification of the second expansion module, further determines that the expansion module corresponding to the test interface is the second expansion module, and then returns second test data; the description of the return of the second test data by the intelligent terminal may refer to the description of the return of the first test data in step S204, which is not repeated herein.

Step S208, determining a test result for the expansion module interface according to the first test data and the second test data.

After receiving the first test data and the second test data, the test control device verifies whether the first test data corresponds to the first expansion module or not, and whether the second test data corresponds to the second expansion module or not, determines the expansion function supported by the interface of the expansion module and the expansion function not supported by the interface of the expansion module according to the verification result, and takes the determined content as a test result.

In one embodiment, in order to further ensure the comprehensiveness of the test, the test control device may determine whether the protocol format and the data content of the first test data match the first expansion module, and if so, determine that the expansion module interface of the intelligent terminal supports the first expansion module; or, the test control device may further determine whether the protocol format and the data content of the second test data match the second expansion module, and if so, determine that the expansion module interface of the intelligent terminal supports the second expansion module.

In the method for testing the expansion module interface of the intelligent terminal, the test control equipment configures a first expansion module for the test interface and generates a first link negotiation response corresponding to the first expansion module; the test control equipment sends a first link negotiation response to the intelligent terminal through the test interface so that the intelligent terminal returns first test data through an expansion module interface connected with the test interface; after receiving the first test data, the test control device reconfigures a second expansion module with different expansion function types with the first expansion module for the test interface, and generates a second link negotiation response corresponding to the second expansion module, so that the intelligent terminal returns the second test data through the expansion module interface, further the test control device determines a test result aiming at the expansion module interface according to the first test data and the second test data, the test control device configures the expansion modules with different expansion function types for the test interface, tests various expansion modules for the expansion module interface of the intelligent terminal, and the test efficiency is improved.

In the test process, whether an expansion module interface of the intelligent terminal supports one of the expansion modules is tested, which can be regarded as a round of test; when a round of test is performed, the test control device needs to perform link negotiation with the intelligent terminal so that the intelligent terminal can acquire the expansion module to be tested. The link negotiation process between the test control device and the intelligent terminal may be: the intelligent terminal transmits a link negotiation request to the test interface through the expansion module interface, and the test interface sends the link negotiation request to the test control equipment; after receiving the link negotiation request, the test control equipment determines an expansion module and generates a link negotiation response corresponding to the expansion module; the test control device sends the generated link negotiation response to the test interface, and the test interface transmits the link negotiation response to the expansion module interface of the intelligent terminal, so that the intelligent terminal can acquire the expansion module to be tested according to the link negotiation response. The test control device determines the expansion module and generates a corresponding link negotiation response, so that the intelligent terminal obtains the related implementation manner of the expansion module to be tested according to the link negotiation response, which may be described in step S202, and is not repeated herein.

If the same expansion module interface needs to be tested whether the RS485 meter reading module, the start acquisition module and the ammeter control module are supported, three rounds of testing exist for the expansion module interface, wherein the test control equipment can be used for receiving test data returned by the intelligent terminal as a mark for completing one round of testing. After the test control equipment completes one round of test, if a new round of test is to be entered, the test interface needs to be manually plugged to trigger the intelligent terminal to resend the link negotiation request, and the new round of link negotiation is performed to realize the new round of test; therefore, the artificial plug operation triggers to enter a new round of expansion module test, and the test efficiency is reduced.

Based on the above, in order to further improve the test efficiency, after receiving the first test data, the test control device may send a hardware initialization instruction to the intelligent terminal, so as to trigger the intelligent terminal to send a link negotiation request of a new round of test. Taking an example of testing whether the expansion module interface supports the first expansion module and the second expansion module, description is made: the intelligent terminal sends a first link negotiation request to the test control equipment; after receiving the first link negotiation request, the test control device determines a first expansion module from a plurality of preset (prestored) expansion modules, and returns the generated first link negotiation response to the intelligent terminal; the intelligent terminal can determine an expansion module to be tested (namely, an expansion module configured by test control equipment for a test interface) as a first expansion module according to the first link negotiation response, and then return first test data to the test control equipment; after receiving the first test data, the test control device can determine that the test of the one-round expansion module is completed, and send a hardware initialization instruction to the intelligent terminal so as to enter the test of the new one-round expansion module; after receiving a hardware initialization instruction of the test control equipment, the intelligent terminal generates a second link negotiation request and sends the second link negotiation request to the test control equipment; after receiving the second link negotiation request, the test control device selects a second expansion module with different expansion function types from a plurality of prestored expansion modules, generates a corresponding second link negotiation response and sends the second link negotiation response to the intelligent terminal.

In one application scenario, if the original local function of the intelligent terminal is a function of communicating with the electric meter, the corresponding module is an electric meter communication module (e.g., a carrier communication module), and the electric meter communication module may be understood as a local communication module, and the corresponding interface is a local communication interface (it will be understood that "external" is referred to in the following description with respect to "local" herein, for example, the external expansion module interface is referred to as a local communication interface). In order to further improve the data transmission efficiency in the test stage, the test control device may send a test instruction carrying a management channel identifier and a data channel identifier to the intelligent terminal before performing link negotiation, so that the intelligent terminal may determine a management channel of the test interface according to the management channel identifier, and determine a data channel of the test interface according to the data channel identifier; wherein the management channel is used for transmitting link negotiation instructions (the link negotiation instructions may include link negotiation requests and/or link negotiation responses), and the data channel is used for transmitting test data.

Specifically, the test control device may generate a test instruction carrying a management channel identifier and a data channel identifier according to a protocol format of the ammeter communication module, and transmit the test instruction to a local communication interface of the intelligent terminal; after receiving the test instruction, the intelligent terminal analyzes the test instruction to obtain a management channel identifier and a data channel identifier, determines a management channel according to the management channel identifier, and determines a data channel according to the data channel identifier; when the intelligent terminal sends a link negotiation request to the test control equipment, the intelligent terminal can determine a management channel of the test interface according to the management channel identification and transmit the link negotiation request to the management channel of the test interface; when the intelligent terminal sends test data to the test control equipment, the data channel of the test interface can be determined according to the data channel identification, and the test data is transmitted to the data channel of the test interface. Correspondingly, when the test control device sends the link negotiation response to the intelligent terminal, the management channel of the test interface can be determined according to the management channel identification, and the link negotiation response is transmitted to the management channel of the test interface. It is understood that the link negotiation request may refer to a first link negotiation request and a second link negotiation request, the link negotiation response may refer to a first link negotiation response and a second link negotiation response, and the test data may refer to first test data and second test data.

In order to further improve the efficiency of the intelligent terminal returning test data in the test process, the test control device can acquire a plurality of extended function protocols corresponding to the plurality of extended modules, generate test instructions according to the plurality of extended function protocols, and send the test instructions carrying the plurality of extended function protocols to the intelligent terminal; the intelligent terminal analyzes the test instruction to obtain a plurality of extended function protocols, and performs corresponding extended function processing according to the extended function protocols to obtain corresponding test data.

In some application scenarios, if the intelligent terminal is provided with multiple expansion module interfaces, in order to further improve the test efficiency, the test control device may test the multiple expansion module interfaces at the same time, and correspondingly, each test interface is connected to a different expansion module interface, and the test control device configures a corresponding expansion module for each test interface (since the tests of the multiple expansion interfaces are performed at the same time, the expansion module of each test interface may also be referred to as an expansion sub-module), where the first expansion module mentioned in step S202 may include multiple expansion sub-modules, where each expansion sub-module corresponds to a different test interface.

The expansion sub-modules configured for each test module may include at least two expansion sub-modules with the same expansion function type, for example, when the test interfaces are three, the expansion sub-modules included in the first expansion module may be: two RS485 meter reading modules and one open acquisition module can also be three open acquisition modules.

However, in some application scenarios, if multiple expansion module interfaces of the intelligent terminal are tested according to the above configuration scheme (including at least two expansion sub-modules with the same expansion function type in the expansion sub-modules configured for each test module), it is difficult to ensure that multiple expansion module interfaces of the intelligent terminal can simultaneously support expansion functions with different expansion function types according to the obtained test result; for example, the intelligent terminal has three expansion module interfaces, if in actual use, the three expansion module interfaces need to support the RS485 meter reading module, the access acquisition module and the ammeter control module respectively, if testing is performed according to the above configuration scheme, it is difficult to ensure that the three expansion module interfaces of the intelligent terminal can support expansion functions with different expansion function types at the same time.

To further ensure the actual usability of the intelligent terminal, in one embodiment, the type of the extended function of the extended sub-module configured by the test control device for each test interface may be different; specifically, the test control device may select multiple extension modules of an extension function type from multiple extension modules, configure each test interface according to the selected multiple extension modules, generate corresponding link negotiation responses, send the link negotiation responses to the intelligent terminal through the corresponding test interfaces, and the intelligent terminal may determine extension modules of the corresponding connected test interfaces according to the link negotiation responses (i.e., multiple first link negotiation responses) received by each extension module interface, and return corresponding test data through the corresponding test interfaces; after receiving the test data transmitted by each test interface, the test control device reconfigures the second expansion module for each test interface; when the test control device reconfigures the second expansion module for each test interface, the test control device may adjust the sequence of each expansion sub-module in the first expansion module, so that the expansion function types of the expansion sub-modules corresponding to any one test interface are different before adjustment and after adjustment, and the first expansion module after the sequence adjustment is used as the second expansion module.

TABLE 1

	Before the sequence adjustment	After the sequence is adjusted
			Test interface	First expansion module	Second expansion module
A	RS485 meter reading module	Ammeter control module
			B	Entry collection module	RS485 meter reading module
C	Ammeter control module	Entry collection module

Illustratively, as shown in table 1, before the adjustment, the extension sub-modules corresponding to the three test interfaces A, B and C (i.e., the order of the respective extension sub-modules in the first extension module) are respectively: the RS485 meter reading module, the start acquisition module and the ammeter control module, the test control equipment adjusts the sequence of three expansion sub-modules in the first expansion module, and the second expansion module obtained after adjustment is: and (5) entering an acquisition module, an ammeter control module and an RS485 meter reading module.

After the second expansion module is obtained, the test control device generates corresponding link negotiation responses (i.e. a plurality of second link negotiation responses), and transmits the corresponding link negotiation responses to the expansion module interface of the intelligent terminal through the corresponding test interface.

In order to better understand the above method, an application example of the method for testing the interface of the expansion module of the intelligent terminal is described in detail below.

In this application example, as shown in fig. 3b, a test system of a new-generation intelligent terminal (i.e., intelligent terminal) includes a test control device and a test interface, where the new-generation intelligent terminal is provided with a local communication interface and an external expansion module interface (i.e., expansion module interface); the test control device can interact with the local communication interface and the test interface, and the test interface is connected with the external expansion module interface.

The test interface may be responsible for performing data format conversion between the test control device and the intelligent terminal, specifically, if the expansion module interface of the intelligent terminal is implemented based on USB2.0 and communication of the test control device is implemented based on serial port or ethernet, the control chip MCU of the test interface may convert instructions or data (such as link negotiation request and test data) transmitted by the expansion module interface from the USB interface data format to the serial port data format or ethernet data format of the test control device, and may also convert data (such as link negotiation response) sent by the test control device from the serial port data format or ethernet data format to the USB interface data format.

The method for testing the interface of the expansion module of the intelligent terminal provided by the application example is described below with reference to fig. 3 a.

Step S302, the intelligent terminal starts to operate normally under normal working voltage, the test control equipment generates a test instruction according to the expansion function protocol, the management channel identifier and the data channel identifier of each expansion module according to the protocol format of the ammeter communication module, and sends the test instruction to a local communication interface of the intelligent terminal, wherein the expansion function protocol of the four expansion modules can comprise the following information: meter reading information (meter reading file, meter reading task and meter reading scheme), access acquisition parameters, remote control tripping command and 4G communication parameters.

Step S304, after receiving the test instruction through the local communication interface, the intelligent terminal analyzes the test instruction to obtain an extended function protocol, a management channel identifier and a data channel identifier of each extended module; the intelligent terminal generates four link negotiation requests, determines a management channel of the test interface according to the management channel identification, and transmits the four link negotiation requests to the management channel of the corresponding test interface A, B, C, D through four external expansion module interfaces respectively.

Step S306, the test control device obtains the link negotiation request of the intelligent terminal through the management channel of the test interface, generates a corresponding link negotiation response according to the configured expansion module, and sends the link negotiation response to the intelligent terminal through the management channel of the corresponding test interface, so that the intelligent terminal determines the expansion modules of the 4 test interfaces.

Step S308, after determining the expansion modules of the 4 test interfaces, the intelligent terminal processes according to the expansion function specifications of the corresponding expansion modules to obtain corresponding test data, determines the data channels of the test interfaces according to the data channel identifiers, and transmits the corresponding test data to the data channels of the test interfaces through the 4 expansion module interfaces. Illustratively, the corresponding test data received by the test control device may include the following:

The test control equipment obtains a meter reading data command sent by the intelligent terminal through an external expansion module interface connected with the test interface A through a data channel of the test interface A. And the test control equipment returns corresponding data to the intelligent terminal through the data channel of the test interface A according to the ammeter data reading command.

The test control equipment acquires a relay action command sent by the intelligent terminal through an external expansion module interface connected with the test interface C through a data channel of the test interface C, and returns corresponding data to the intelligent terminal according to the relay action command.

The test control equipment acquires a 4G communication connection command sent by the intelligent terminal through an external expansion interface connected with the test interface C through a data channel of the test interface D, and returns corresponding data to the intelligent terminal according to the 4G communication connection command.

Step S310, after receiving corresponding test data returned by the intelligent terminal through 4 test interfaces, the test control device judges whether each expansion module interface of the intelligent terminal supports a corresponding expansion function in the round of test; and the test control device sends a hardware initialization instruction to the intelligent terminal to enter a new round of test.

Step S312, the intelligent terminal restarts after receiving the hardware initialization instruction, and sends a link negotiation request to the test control equipment again.

In step S306, after receiving the link negotiation request sent again by the intelligent terminal, the test control device reconfigures the extension modules for the 4 test interfaces, where the reconfigured extension modules corresponding to the test interfaces A, B, C and D may be: the system comprises a 4G communication module, an RS485 meter reading module, a start acquisition module and an ammeter control module; and generating a corresponding link negotiation response according to the reconfigured expansion module, and returning the response to the intelligent terminal so as to perform a corresponding expansion module interface test.

The method can simulate the functions of all external expansion modules of the new-generation intelligent terminal and provide various data required by the intelligent terminal in the testing process, thereby replacing matched external equipment required by the testing, such as an ammeter, a carrier or micro-power wireless communication module, a collector and a switching value input device.

The method can also configure the expansion module for the test interface so as to perform blind insertion test on the expansion module interface connected with the test interface, thereby improving the test efficiency.

The method can simulate error data and error command frames, and test the processing capacity and reliability of the new generation intelligent terminal on external error data and error commands.
