Description
Technical Field
The application belongs to the technical field of power distribution network information transmission management and control, and particularly relates to a power distribution network safety information management and control method and a power distribution network safety information management and control platform.
Background
The transmission of the power information of the power distribution network is often carried out between a foreground terminal and a background terminal, and when the foreground terminal and the background terminal which are communicated with each other in the 4G network transmit huge power information of the power distribution network, the adverse effect on the application function can be formed only by the occurrence of the missing of the information message of the power information of the power distribution network; therefore, how to provide a barrier to the delivery of a 4G network that is stable is an important element.
Modes of ensuring stable 4G network delivery now are:
(1) The information message retransmission mode is achieved through the program, and the mode has the advantages that the session layer standard can execute the flexible change and can be matched with different 4G network scenes, however, because the platform power information retransmission flow is coordinated through the whole kernel, the retransmission time consumption is not low, and the huge kernel utilization rate is also consumed;
(2) The 4G module connected with the foreground terminal achieves the region power information retransmission mode, so that the time consumption of retransmission is reduced, the mode has the advantages that the retransmission mode is achieved to be a special circuit board, the treatment time consumption is less than that of a kernel, the kernel is synchronous, the kernel cannot cooperate with the treatment of region power information transmission, and the efficiency of the kernel can be improved efficiently.
Two current drawbacks associated with the retransmission platform according to the dedicated circuit board are described below:
(1) After the kernel prepares the power information of the area to be transferred, the 4G module transfers the power information of the area to be transferred through the main memory kernel, performs message packaging, and transfers the information into the 4G network; after the power information receiving party of the platform area obtains the information message, a feedback message is returned to prompt the foreground terminal that the power information of the platform area is successfully received; after a feedback message is obtained by a kernel for receiving the foreground terminal, informing the kernel that the current information message is treated by a suspension method, and emptying a used main stored message pool;
the core for receiving the foreground terminal does not obtain the feedback message in a time interval, and activates a retransmission mode, which retransmits the first transmitted unidentified information message, and the platform has the defects that:
when the information message is to be transferred again, the 4G module is to acquire the power information of the platform region in the host computer main memory through the platform channel to execute the transfer again, so that the transfer time consumption is increased.
(2) After the kernel prepares the electric power information of the platform area to be transferred, the 4G module transferring kernel takes out the electric power information of the platform area through the main memory, synchronously sends the electric power information of the platform area into a message pool of the main memory of the 4G module, packs the electric power information of the platform area, and sends the electric power information of the platform area into the 4G network, so that the message pool of the electric power information of the platform area in the main memory can be emptied as long as the information message reaches the 4G network, and a feedback message is returned after the background terminal obtains the information message to prompt the foreground terminal that the electric power information of the platform area is successfully collected; after the kernel for receiving the foreground terminal obtains a feedback message, the message pool on the network card is emptied, the kernel for receiving the foreground terminal does not obtain the feedback message in a time interval, a retransmission mechanism is activated, the first transmitted information message which is taken out from the message pool in the 4G module and is not recognized is retransmitted, and a timing unit is restarted; the platform has the following defects:
the message pool on the 4G module is emptied by feedback message arrival, the time consumption is not small in the 4G network, the message is not determined to arrive in real time, the message pool is not emptied efficiently, and the information message is transmitted after delay, so that the safety is poor.
