it should be noted that: the real-time monitoring of the power distribution network requires that each automatic terminal and the main station carry out real-time communication, and most of the current communication is carried out by using question-answer messages such as 101 and 104, and the interaction frequency of the communication messages is generally within 1-2 seconds. At present, most of domestic distribution network automatic switches are provided with automatic terminals, have communication functions, communicate with an automatic distribution network master station in real time, and use only 1 SIM card or 1 fiber channel independently when the terminals communicate with the master station, so that the reliability is poor. When the SIM card arrears and stops, network equipment is damaged, optical fiber is broken, and the like, communication between the terminal and the master station is interrupted, and the operation monitoring of the dispatching master station is seriously influenced.

The mode (2) is mainly used in a radial communication network of a distribution network single, the loop of the radial optical fiber network is realized through the cooperation of the multiplexing switching device and the substation communication trunk loop exchanger, and when a certain section of optical cable on the optical fiber network is interrupted due to the conditions of network equipment damage, optical fiber cable breakage and the like, the substation communication trunk loop exchanger is automatically switched to restore communication with an optical cable rear section electric room through the multiplexing switching device.
The key point of the multi-network type multi-channel power distribution automation communication network switching device is that the S end (service end) and the C end (client end) of the multi-channel switching device are automatically and synchronously switched, as described in the following method.
The method comprises the following steps:
step 101, setting a plurality of communication channels at a server side and a client side, and setting channel parameters and detection parameters;
it should be noted that, in one embodiment, the user writes the channel form and the IP address configuring the C-side channels 1, 2, 3 on the S-side device of the switching apparatus, sets the detection period T1 (2-30 seconds), the channel timeout time T2 (5-2000 milliseconds), sets the size of the test data packet (proposal: 10-1000 bytes), sets the number of test packets (3-10), and sets the default service data communication channel (default is channel 1); simultaneously, the channel forms and the IP addresses of the S-side channels 1, 2 and 3 are written on the C-side equipment, and a default communication channel (the proposal is consistent with the S-side setting and is the channel 1 by default) is set.
102, monitoring the communication state of each communication channel by the service end based on the detection parameters, and recording the average time delay of the packet returning and the packet loss rate;
it should be noted that, in one embodiment, on an S-terminal device of the switching device, three channels of the C-terminal device send data packets according to the size and the number of packets set by a user at intervals of T1, detect network packet-returning delays of channels 1, 2 and 3, wait for C-terminal packet-returning according to a channel timeout time T2, record that a channel is normal and record packet-returning average delay and packet loss rate when the packet-returning time of a channel is not less than or equal to T2;
further, in one embodiment, when the packet returning time of the channel is all greater than or equal to T2, the channel interruption is recorded, and the packet loss rate is 100% after Bao Yanshi infinity; and simultaneously, sending out a channel abnormality alarm to inform an upper computer or an upper system.
Step 103, when each communication channel is not completely interrupted, determining the communication quality of each channel according to the communication state, the packet returning average delay and the packet loss rate of the communication channel, and sorting the channels according to the communication quality;

Step 104, when the state of the default communication channel is normal, jumping to step 102 to enter the next detection period after delaying the time of one detection period;
it should be noted that, the S-terminal device determines whether the current channel status is normal, if the channel status is normal, no switching is needed, and on the S-terminal device, the time is delayed by T1, the step S2 is skipped, and the next switching period is entered.
Step 105, when the state of the default communication channel is abnormal, the server controls the controlled switch to the channel with optimal communication quality, and triggers the client through the channel with optimal communication quality, so that the client controls the controlled switch to the channel with optimal communication quality.
It should be noted that, the S-terminal device determines whether the current channel status is normal, if the channel is abnormal, the channel needs to be switched, and when switching, the S-terminal device first controls the controlled switch of the side to switch to the channel with the smallest sequence number, and then notifies the C-terminal to switch the controlled switch to the corresponding channel through the channel with the smallest sequence number.
