Specifically, the management core has an uplink interface connected to the concentrator and a downlink interface connected to various home appliances.
In the related art, the upgrading process of the internet of things electric meter is that, first, the superior device of the internet of things electric meter needs to determine the electric meter to be upgraded, and then the electric meter during batch upgrading is subjected to grouping and multicast key negotiation. The superior device adopts a multicast mode to issue an upgrade file. Each electric meter to be upgraded needs to download an upgrade file from the multicast group route, and upgrade is performed in the idle time of the equipment. For the situation that the upgrade file is not received or is incomplete, the superior equipment needs to determine through inquiry or active reporting by the ammeter, and then retransmits the upgrade file in a point-to-point mode.
In the above process, the version information of each internet of things electric meter may not be the same, and if the upper device sends the complete upgrade file, each internet of things electric meter downloads the upgrade file in the same time period, which makes the load of the communication channel in the time period larger. If the upper-level device sends the incremental upgrade file to the corresponding internet of things ammeter, the upper-level device needs to occupy a communication channel for a long time when transmitting the upgrade file. In conclusion, the electric meter upgrading efficiency of the Internet of things is low.

Embodiments of the application are described in further detail below with reference to the drawings.
The embodiment of the application provides an electric meter upgrading method of the Internet of things, which is mainly applied to a platform area system. The platform area system comprises a plurality of Internet of things ammeter and at least one superior device. The electric meter of the Internet of things comprises a metering core, a management core and an expansion module. The metering core is responsible for the legal calculation function of the ammeter, namely collecting electricity consumption data such as voltage, current, instantaneous power, active power, reactive power and the like. The management core is responsible for functions such as ammeter display, communication, can also manage and control expansion module. The management core is provided with an uplink interface and a downlink interface, wherein the uplink interface is connected with the superior equipment, and the downlink interface is connected with various household equipment. The superordinate device may be a concentrator or collector.
Specifically, the upper-level device is used for executing the method for upgrading the electric meter of the Internet of things, and performs data interaction with the electric meter to be upgraded so as to complete the upgrading process of the electric meter of the physical network. In order to better implement the method, a chip capable of processing the upgrade file is configured in each expansion module of the Internet of things ammeter. Namely, the system has the function of adjusting the upgrade file to be suitable for upgrade files of various version information. Of course, a certain storage space is also needed in the internet of things ammeter to store the upgrade file.
The embodiment of the application provides a main flow description of an electric meter upgrading method of the Internet of things.
As shown in fig. 1:
step S101: and acquiring the ammeter version information and the first IP address of all the ammeter to be upgraded.
The electric meter to be upgraded is an electric meter which needs to be upgraded and meets the upgrading conditions. The ammeter version information is version information of an ammeter. The first IP address is an IP address of the electricity meter.
It can be appreciated that, when the electric meter version information of the electric meter to be upgraded is obtained, the electric meter to be upgraded needs to be determined from all electric meters. Specifically, the process of determining the electric meter to be upgraded is: first, current version information of an upgrade file and ammeter version information of all the ammeter are acquired. And then, determining the upgradeable electric meters according to the current version information and the electric meter version information of all the electric meters, and sending a start transmission command to the upgradeable electric meters so that the upgradeable electric meters confirm whether the upgrade conditions are met. And finally, determining the electric meter to be upgraded according to the received confirmation result.
In the above process, the current version information is the version information of the upgrade file, and the upgradeable electric meter is the electric meter to be upgraded, i.e. the version information of the electric meter is lower than the current version information. Since the upgrade result of each time of the electric meter may be successful or failed, the version information of all electric meters is inconsistent, that is, some electric meters need to be upgraded, and some electric meters do not need to be upgraded. It will be appreciated that the upgradeable meter is not fully upgradeable. Whether the electric meter can be upgraded or not also needs to see whether the software and hardware version of the electric meter is compatible with the upgrade file. Therefore, the superior device needs to send a start transmission command to the upgradeable electricity meter. The start transmission command includes version information of compatible software and hardware of the upgrade file.
Step S102: grouping the electric meters to be upgraded according to the electric meter version information to obtain a plurality of groups of electric meters with the same electric meter version information.
In all the electric meters to be upgraded, although the electric meter version information of the electric meters may exist differently, there are electric meters with the same electric meter version information. The same upgrade file can be used for the electric meters with the same electric meter version information. Therefore, it is necessary to determine the electric meters having the same electric meter version information so that the electric meters can simultaneously download the upgrade file and upgrade.
Step S103: and obtaining a plurality of groups of multicast addresses according to the first IP address of each electric meter to be upgraded in each group of electric meters.
Wherein, the multicast address is the information needed by the multicast route in the multicast transmission. In multicast transmission, a multicast source needs to configure a multicast route first, that is, a multicast address is set in the multicast route. And then, only the data or the file to be transmitted to the multicast member is transmitted to the multicast route, so that all the multicast members can receive the data or the file.
In the application, the group number of the multicast address is consistent with the version number of the ammeter version information, namely a group of ammeter corresponding to the multicast address is a plurality of ammeter version information of the same ammeter version information. The corresponding relation between the multi-group multicast address and the multi-group ammeter can be determined through the first IP address.
Step S104: and sending a group of multicast addresses, a second IP address of a second multicast route and target version information to the first multicast route, so that one ammeter to be upgraded in a group of ammeter corresponding to the group of multicast addresses sends a target upgrading file to the second multicast route.
The first multicast route is a multicast route of which the upper-level equipment needs to be configured with a multicast address. The second multicast route is a multicast route which needs to receive an upgrade file sent by the electric meter to be upgraded. Obviously, all second multicast routes are first multicast routes. The second IP address is the IP address of the multicast route. The target upgrade file is obtained by processing the upgrade file downloaded by the equipment according to the target version information by the ammeter to be upgraded. The target version information is a version in which the ammeter version information is higher than only ammeter version information corresponding to the multicast address of the first multicast route.
In a specific example, the above procedure is: when the superior device sends the multicast address, the second IP address of the second multicast route and the target version information to one multicast route for the first time, the initial upgrade file is also sent at the same time. The initial upgrade file is an upgrade file for upgrading the electric meter to be upgraded with the lowest electric meter version information to the current version. The group of electric meters corresponding to the transmitted multicast address should be the group of electric meters with the lowest electric meter version information, so that the group of electric meters can complete the upgrading process according to the upgrading file downloaded from the multicast route. Because the multicast addresses of the second multicast route are all configured by the superior device, the sent second IP address enables one of the group of electricity meters to directly send the target upgrade file to the corresponding multicast route. Similarly, the multicast address of the multicast route is configured by the superior device, and one ammeter in each group of ammeter can send the target upgrade file to the second multicast route according to the provided second IP address. Therefore, when the upper-level equipment distributes the upgrade file to the electric meter to be upgraded, only the initial upgrade file needs to be sent. It is understood that the upgrade files may be divided into two types, that is, an upgrade file capable of supporting an upgrade from an initial version to a current version, and an upgrade file capable of supporting an upgrade from one designated version to the current version. The latter is sent by the superior device. Before sending, the upper-level equipment needs to process the upgrade file according to the lowest ammeter version information so as to obtain an initial upgrade file. The method reduces the times of transmitting the upgrade file by the superior equipment, reduces the size of the upgrade file to be transmitted, and can reduce the occupancy rate and the occupied time of the communication channel to a certain extent, thereby achieving the effect of improving the upgrade efficiency of the electric meter of the Internet of things.
It should be noted that, since the processing of the upgrade file according to the target version information is irreversible, in order to ensure the feasibility of the above technical means, the order in which the superior device transmits the multicast addresses should refer to the electric meter version information, that is, in order of the electric meter version information from low to high.
It can be understood that, after the superior device sends the multicast address, the second IP address and the target version information to the first multicast route, all the electric meters of the group of electric meters can be downloaded from the first multicast route at the same time, and the upgrade process is completed according to the free time of the superior device. And then, after one ammeter in the group of ammeter finishes the upgrading process, the downloaded upgrading file is processed according to the target version information so as to obtain the target upgrading file. Obviously, in the process, one group of electric meters is upgraded firstly, and after the upgrade is completed, the other group of electric meters is upgraded. The occupation rate of the communication channel is reduced in the same time period, and the speed of downloading the upgrade file is ensured.
Further, each multicast route and each meter for sending the target upgrade file to the second multicast route is selected.
Specifically, the method for determining the second multicast route includes: and acquiring the first physical location of the electric meter to be upgraded corresponding to the multicast address of the second multicast route and the second physical location of all the multicast routes. And then determining a second multicast route according to all the first physical locations of the group of electric meters and all the second physical locations of the available multicast routes.
The first physical location is the location information of the electric meter to be upgraded, and the second physical location is the location information of the multicast route. And when all the first physical positioning of the group of electric meters is obtained, determining the target physical positioning according to the first physical positioning of all the electric meters. The target physical location is the location of the point location closest to the sum of the distances of each of the first physical locations. Algorithms for implementing the above functions are prior art means in the related art, and thus, they will not be described in detail herein.
After the target physical location is determined, determining the multicast route closest to the target physical location according to the second physical locations of all available multicast routes, and taking the multicast route as a second multicast route. It can be understood that, except that the initial upgrade file is sent to the multicast route by the superior device, the target upgrade file is sent to the multicast route by the electric meter, so that in the whole upgrade process, most of the time is interaction between the electric meter and the multicast route, and therefore, the closer the distance between the second multicast route and the electric meter corresponding to the multicast address thereof is, the less time the electric meter occupies a communication channel when downloading the upgrade file. Wherein the first determined second multicast route is in fact the first multicast route. It should be noted that, when configuring a multicast address for a multicast route, the principle that only one multicast address is used for a multicast route should be inherited. Of course, in some specific embodiments, only one multicast route may be set.
The method for determining the electric meter to be upgraded for sending the target upgrade file to the second multicast route comprises the following steps: firstly, a first physical location of an ammeter to be upgraded corresponding to a multicast address of a first multicast route is obtained, and then a target ammeter is determined according to all the first physical locations of the ammeter group and a second physical location of a second multicast route. And the target ammeter is the ammeter used for sending the target upgrade file to the second multicast route. Similarly, the electric meter to be upgraded closest to the second physical location of the second multicast route is still determined according to all the first physical locations of the electric meters in the group, and is used as the target electric meter. The distance between the second multicast route and the target ammeter is enabled to be closer, and therefore the time of the communication channel occupied by the target ammeter for sending the target upgrade file to the second multicast route is reduced.
In some specific embodiments, the upper device may also choose not to send the second IP address and the target version information of the second multicast route to the electric meter to be upgraded through the first multicast route, but to directly send the second IP address and the target version information of the second multicast route to the target electric meter.
The method for upgrading the electric meter of the Internet of things provided by the embodiment of the application enables the occupancy rate of each time period to the communication channel to be lower in the whole upgrading process of the electric meter of the Internet of things, so that the upgrading efficiency is higher.
Fig. 2 is a schematic diagram of an internet of things electric meter upgrading system according to an embodiment of the present application, which can execute the above method for upgrading an internet of things electric meter, and the above embodiment can be referred to, and repeated description thereof will not be repeated here.
The internet of things electric meter upgrading system as shown in fig. 2 comprises an acquisition module 21, a grouping module 22, an address determining module 23 and a sending module 24, wherein:
the obtaining module 21 is configured to obtain the version information and the first IP address of all the electric meters to be upgraded.
