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

The existing new energy edge side communication module has corresponding error processing measures, and in the new energy edge side communication module configuration and fault resolution, if the local network signal is poor, a directional antenna and a large gain antenna can be adopted; if the switching of the 2G/3G/4G signals is more frequent, the following measures are adopted for test verification: forcing the network system to be 2G, 3G or 4G according to the local network condition by expanding a parameter AT instruction (an instruction applied to connection and communication between the terminal equipment and the PC application); a different carrier SIM card is replaced. In the communication fault and processing of the automatic monitoring system of the transformer substation, the error processing method comprises the following steps: analysis shows that these faults occur due to problems with the interfaces of the network lines. The correct processing mode is to cut off the crystal head of the net wire, replace a new joint, connect the net wire and then test. The communication system of the photovoltaic power station is normal, so that faults can be found in time and processed quickly, the accident is prevented from being enlarged, and the loss of electric quantity is reduced. Because the construction difficulty of mountain region photovoltaic is great, and some communication cable laying depth can not reach the standard requirement, leads to communication cable easily to break, and heavy current cable, equipment are more, and easily form the interference to communication cable, and fortune dimension personnel's daily inspection can't all examine in place with all equipment, only can batch daily, have important inspection, and field equipment communication reliability is very important this moment.

For example, if the restarted communication program has no program error, it is indicated that the restarted communication program may be used for normal communication of the new energy edge side communication module, and the restarted communication program may be used as a communication program after fault processing of the new energy edge side communication module, and the communication work of the new energy edge side communication module may be performed by using the restarted communication program. Therefore, the normal operation of the passing module can be ensured, the fault removal process of the new energy edge side communication module can be realized, and the operation efficiency of the new energy edge side communication module is improved.
S110, reinstalling the communication program for the new energy edge side communication module and taking the reinstalled communication program as the communication program after the new energy edge side communication module fault processing when the reinstalled communication program has a program error.
For example, if there is a program error in the communication program after the restart, the communication program may be reinstalled for the new energy edge side communication module, and the reinstalled communication program may be treated as a communication program after the new energy edge side communication module has failed. Therefore, based on the reinstalled communication program, the correctness of the communication program can be ensured, so that the normal communication work of the new energy edge side communication module is facilitated, the fault removal process of the new energy edge side communication module can be realized, and the new energy edge side communication module performs the normal communication work.

S206, taking the communication program of the new energy edge side communication module corresponding to the target fault position as a target program.
The target fault location may be a location point where a fault occurs, for example, may be a location of a communication module at an edge side of a new energy source where a fault occurs.
For example, from the failure location area, the failure location point where the failure occurs may be further determined, and thus, the specific new energy edge side communication module where the failure occurs may be further determined. The communication program of the new energy edge side communication module with the fault can be further determined as the target program, so that the target program of the new energy edge side communication module with the fault can be isolated. Therefore, the situation that the wrong target program blocks the normal communication of the new energy edge side communication module can be avoided, and the communication is continued by using the communication program with the normal communication by isolating the target program with the error, so that the operation efficiency of the new energy edge side communication module can be improved.
In this embodiment, the new energy edge side communication module can be subjected to fault recurrence processing to obtain a fault location area where a fault occurs, and further, a target fault location where the fault occurs is determined from the fault location area, and a communication program of the new energy edge side communication module corresponding to the target fault location is used as a target program, so that the new energy edge side communication module where the fault occurs and a specific fault point can be determined, thereby being beneficial to the efficiency of fault processing of operation and maintenance personnel.

And replacing another new energy edge side communication module for isolation positioning until the fault on the communication bus is eliminated after the communication isolation equipment is installed, namely, positioning a target fault position, further isolating the target fault position, further marking the fault position and storing and recording fault information. Therefore, the communication program of the new energy edge side communication module with faults can be isolated, the phenomenon that the error communication program blocks the normal communication of the new energy edge side communication module is avoided, the normal communication is realized, and the operation efficiency of the new energy edge side communication module is improved.

The signal indication device receives the signal indication command and displays the indication lamp with fault. For example, the signal indicating device displays a corresponding signal, if the new energy edge side communication module is abnormal, the signal indicating device displays green, and if the new energy edge side communication module is faulty, the signal indicating device displays red. After the target fault position is determined, the new energy edge side communication module with the fault can be quickly isolated, namely, the new energy edge side communication module at the target fault position is quickly isolated, so that other new energy edge side communication modules without the fault can continue to perform communication work, the target fault position can be marked, and fault information is stored and recorded.
In this embodiment, the signal indication device indicates the target fault position through the indication lamp according to the signal indication command, so that the operation and maintenance personnel can quickly determine the new energy edge side communication module and the fault position, thereby improving the efficiency of the operation and maintenance personnel in processing the fault.
