Description
Technical Field
The invention relates to the technical field of communication application, in particular to a data transmission system and a data transmission method.
Background
In the existing power distribution network, when a power distribution network is in short circuit or has a ground fault, a fault point needs to be found and a fault section needs to be isolated as soon as possible. The short circuit and earth fault indicator is a fault positioning device with high cost performance, can alarm and indicate faults locally, and can be matched with other distribution network automation devices and software through a communication network to realize functions of remote transmission of fault information, centralized monitoring of operation and fault data, decision support of fault section isolation measures and the like. The fault location system formed by the participation of the fault indicators thus becomes an essential part of the fault alarm network.
The fault positioning system based on the fault indicator mainly comprises the fault indicator, a monitoring terminal and a main station. The fault indicator realizes short circuit and earth fault judgment, the monitoring terminal realizes indicator fault data acquisition and remote transmission, and the master station realizes data analysis, display, decision and execution. In order to realize remote transmission of fault data to a master station, the following communication modes are mainly adopted at present: the monitoring terminal communicates with the monitoring terminal through a General Packet Radio Service (GPRS) network (hereinafter referred to as communication mode one).
The structure of the distribution network fault positioning system for communication between the communication mode and the master station is shown in detail in attached figure 1, and figure 1 is a schematic structural diagram of a communication system formed by a monitoring terminal and the master station in the related art.
The communication mode is that the indicator uploads data to the monitoring terminal through short-distance wireless communication, and then the data are remotely transmitted to the master station through GPRS by the monitoring terminal.
As shown in the attached drawing 1, each telegraph pole is provided with one monitoring terminal, and each monitoring terminal collects the fault information of 3-9 fault indicators. When a fault occurs, the fault indicator actively uploads data to the monitoring terminal of the rod at once, and the monitoring terminal remotely transmits fault information to the main station by adopting a balanced power 101 protocol. When there is no fault, the indicator uploads the line load data to the terminal according to a certain period.
The fault indicator works in a mode that the short-distance radio frequency communication of the fault indicator can be in a dormant state for a long time so as to reduce power consumption.
The radio frequency communication distance of the fault indicator is short (30-50 meters), data cannot be directly transmitted to a main station, and the fault indicator needs to be installed at a nearby monitoring terminal for forwarding. Due to the limitation of communication distance, one terminal generally collects data of 3 groups of 9 fault indicators at most, and the number of the terminals is large.
The disadvantages of this communication approach are: firstly, a monitoring terminal communicates with a main station through GPRS, each terminal needs to be provided with an SIM card, and a data flow packet needs to be customized. Due to the large number of terminal points, the traffic cost is high.
Secondly, in remote areas, GPRS signals are weak in some areas or no signals exist at all, fault data cannot be transmitted to a main station remotely, and fault positioning cannot be achieved.
Thirdly, each group (usually 3) of fault indicators needs to be configured with one monitoring terminal to realize the collection and remote transmission of fault data, and the number of the monitoring terminals is large compared with other communication modes, thereby increasing the purchasing and operation and maintenance costs.
In view of the above-mentioned problems that in the related art, the monitoring terminal uses GPRS to perform data communication with the master station, which results in high communication charges and maintenance costs, and data transmission is obstructed due to instability of GPRS signals, no effective solution has been proposed at present.
Disclosure of Invention
The embodiment of the invention provides a data transmission system and a data transmission method, which at least solve the technical problems of high communication charge and maintenance cost and data transmission obstacle caused by the instability of GPRS signals due to the fact that a monitoring terminal uses GPRS to carry out data communication with a main station in the related technology.

Compared with other communication modes of data remote transmission, the communication mode of the long-distance micropower ad hoc network of the monitoring terminal has the following advantages:
the monitoring terminal is powered by the solar cell panel, and a standby battery with large capacity is arranged in the terminal, so that the monitoring terminal cannot influence data communication due to lack of electric energy.
The monitoring terminal adopts a honeycomb Zigbee networking technology and has the capability of automatically searching a communication link by equipment. If a certain terminal on the original communication link fails, the subsequent equipment of the link can realize the data transmission to the superior level by searching a new communication link, so as to ensure the smooth data transmission;

GPRS communication needs to use an SIM card, needs to customize a data flow packet, and is high in cost; the long-distance wireless networking communication uses free and open wireless frequency bands without any data traffic cost.
The Ad hoc network monitoring Terminal has various data communication interfaces, and in places without distribution network automation Terminal equipment such as FTU, DTU, distribution Transformer monitoring Terminal (TTU for short), and the like, the Ad hoc network monitoring Terminal can collect data to the intelligent monitoring Terminal at the place with stronger GPRS signals through wireless networking, and remotely transmits the data to a main station through GPRS.
The data transmission system provided in the embodiment of the present application may also be the data transmission structure shown in fig. 4, and fig. 4 is a schematic structural diagram of another data transmission system according to an embodiment of the present invention, in which,
the power distribution network fault accurate positioning system based on the monitoring terminal long-distance micropower ad hoc network communication is composed of a fault indicator 41, a monitoring terminal 42 and a main station 43, and the composition structure of the system is shown in figure 4.
The fault indicator 41 realizes the functions of monitoring line faults and detecting timing line load parameters, and when the faults occur, the fault indicator 41 immediately sends data to the monitoring terminal 42 through short-distance radio frequency communication; when the timing time is up, the fault indicator 41 samples parameters such as line load current and temperature, and sends data to the monitoring terminal 42 through short-distance radio frequency communication. The fault indicator 41 can also receive an instruction sent by the monitoring terminal 42, and perform operations such as card turning, resetting, fault simulation and the like.
The monitoring terminal 42 has a short-distance radio frequency communication interface to realize the acquisition of data of each indicator, and adopts the Zigbee ad hoc network communication technology and other monitoring terminals to form a communication network, through which the data is finally collected to the monitoring terminal 42 at the initial end of the line. The monitoring terminal 42 at the beginning of the line has rich general data communication interfaces (such as an optical fiber communication interface, a wireless GPRS communication interface, a serial communication interface, a power line carrier communication interface, a network port, etc.), and can be conveniently accessed into other data communication networks, and the data of the fault indicator 41 is remotely transmitted to the master station 43 via these communication networks. The monitoring terminal 42 is powered by a solar panel, and a high-capacity lithium battery and a super capacitor are used as a backup power supply, so that the service life of the monitoring terminal is much longer than that of an indicator.
The master station 43 collects fault data sent from each line monitoring terminal 42, and then accurately judges a fault occurring section according to analysis of a distribution network line diagram and the fault data, and performs processing such as fault alarm information screen flipping, fault section coloring, fault data alarm log recording and the like.
The S-RF shown in FIG. 4 is here Short Distance Radio Frequency (Short Distance Radio Frequency) communication.

Each of the data uploading device, the data relay device and the coordinator may mount a fault indicator group, but in a network architecture formed by the data uploading device, the data relay device and the coordinator, the data uploading device must forward state information to the coordinator through the data relay device, and then the coordinator sends the state information to the master station, wherein the data uploading device, the data relay device and the coordinator in the embodiment of the application may be intelligent monitoring terminals with relay functions, and specific functions executed only by different positions in the network architecture are different.
According to the data transmission method provided by the embodiment of the application, the state information reported by the fault indicator group is obtained; the state information is forwarded to the master station through the communication link which is pre-established among the data uploading device, the data transfer device and the coordinator, so that the purpose of guaranteeing smooth data transmission is achieved, the stable technical effect of data transmission is realized, and the technical problems that in the related technology, the communication cost and the maintenance cost are high due to the fact that the monitoring terminal uses the GPRS to carry out data communication with the master station, and data transmission is obstructed due to the instability of GPRS signals are solved.

step S501, a communication link composed of a data transfer device and a data upload device is created according to the data transmission path specified by the coordinator.
Here, before performing the status information data transmission, the coordinator needs to create a communication link with the data relay device and the data uploading device, so that the status information is conveniently transmitted to the master station via the communication link in the later data transmission.
Preferably, the step S501 of creating a communication link composed of the data relay device and the data upload device according to the data transmission path specified by the coordinator includes:

step2, configuring data transmission paths among the data uploading equipment, the data transfer equipment and the coordinator according to the data transmission network architecture;
step3, a communication link is created according to the data transmission path.
Specifically, in combination with steps 1 to 3 in Step S501, the coordinator selects a corresponding data transmission network architecture according to the number and specific placement of the data relay devices and the data upload devices, in this embodiment, the data transmission network architecture may be a tree, a star, or the like, but actually the coordinator, the data relay devices, and the data upload devices are data transmission network architectures constructed based on a cellular network, further, after determining the data transmission network architecture, configuring data transmission paths among the data upload devices, the data relay devices, and the coordinator according to the data transmission network architecture, that is, in the configuration process of the route, the coordinator sets a plurality of data transmission paths between the data upload devices and the data relay devices, and finally, after obtaining the plurality of data transmission paths, creating a communication link according to the data transmission paths, the process of creating the communication link may create the communication link in a "request-response" feedback manner, that is, when the data uploading device sends a communication link request to the data relay device on the specified data transmission path, the data relay device determines establishment of the communication link according to a communication link request feedback response packet.
The creation of the communication link in the embodiment of the present application is only described by taking the above as an example, and is not limited specifically by the method for implementing the data transmission provided in the embodiment of the present application.
Optionally, when the data relay device and the coordinator are respectively in communication connection with the fault indicator group, the forwarding the state information to the master station through the communication links pre-established among the data uploading device, the data relay device, and the coordinator in step S504 includes:
due to the variability of the data transmission system, the method for transmitting data provided in the embodiment of the present application includes the following transmission modes in the process of transmitting the state information to the master station through the communication link pre-established among the data uploading device, the data relay device, and the coordinator:
the first method is as follows: in a conventional manner
Step1, uploading the state information to the data transfer device through the data uploading device;
step2, forwarding the state information to the coordinator through the data transfer equipment;
step3, sending the state information to the master station through the coordinator;
specifically, in combination with steps 1 to 3, the fault indicator group uploads the state information via the data uploading device, and the data transfer device forwards the state information to the coordinator, and finally the coordinator sends the state information to the master station.
Or,
mode two, state information sending mode when adjacent data transfer equipment fails
Step1, forwarding the state information to the coordinator through the data relay equipment appointed by the coordinator;
step2, sending the state information to the master station through the coordinator;
specifically, in combination with Step1 and Step2, it is assumed that the original data transfer device of the data uploading device is device 1, but after the data uploading device uploads the state information to device 1, device 1 does not respond back, and in order to ensure smooth reporting of the state information, the data transfer device (denoted as device 2) that has been designated by the coordinator of the data uploading device forwards the state information uploaded by the data uploading device, and finally the coordinator sends the state information to the master station.
Or,
mode three, reporting the state information of the fault indicator group mounted by the data transfer server
Step1, receiving the state information of the fault indicator group which is sent by the data relay device and is in communication connection with the data relay device;
step2, sending the state information to the master station through the coordinator;
as can be seen from steps S502 and S504, in conjunction with steps 1 and Step2, since the data relay device is also a monitoring terminal, the monitoring terminal also has a corresponding fault indicator group mounted thereon, and therefore, when the data relay device uploads the state information of the fault indicator group mounted on the data relay device, the coordinator receives the state information and then directly forwards the state information to the master station.
Or,
and fourthly, uploading the state information of the fault indicator group mounted by the coordinator
Step1, the state information of the fault indicator group connected with the coordinator in communication is sent to the main station through the coordinator.
In the third mode, the coordinator is also a monitoring terminal, so the coordinator can mount the fault indicator group, and therefore, when the fault indicator group sends the state information to the coordinator, the coordinator forwards the state information to the master station.
