Specifically, the first operating temperature monitoring instruction is a control instruction sent by the system for monitoring the temperature of the first main road device, the first standby road device and the second standby road device in real time; after receiving a first working temperature monitoring instruction, the temperature monitoring module monitors the temperature of the first main path device, the first standby path device and the second standby path device in real time, and stores the monitoring results according to a time sequence to obtain a first temperature monitoring result consisting of three groups of data, namely a first main path device temperature monitoring result, a first standby path device temperature monitoring result and a second standby path device temperature monitoring result; further, under the condition that the same transmission path and the same transmission signal power are obtained based on historical data, in normal temperature change intervals of the first main road device, the first standby road device and the second standby road device, when the first main road device works, a first main road device temperature monitoring result is compared with the normal temperature change interval of the first main road device in real time, if the first main road device temperature monitoring result is in the normal temperature change interval of the first main road device, the first main road device temperature monitoring result is marked as normal temperature, when the first main road device temperature monitoring result does not meet the normal temperature change interval of the first main road device temperature, the first main road device temperature monitoring result is marked as abnormal temperature, and the comparison result is stored as the first temperature analysis result; further, when the first temperature analysis result has abnormal temperature, comparing the first backup path equipment temperature monitoring result, the second backup path equipment temperature monitoring result with the normal temperature change intervals in the first backup path equipment and the second backup path equipment respectively to obtain a second temperature analysis result, and preferentially selecting backup path equipment with normal temperature change during switching; if the two standby channel devices are normal, the selection is preferably carried out according to the transmission performance. Through real-time monitoring the temperature changes of the first main path equipment, the first standby path equipment and the second standby path equipment, when the temperature of a working line is abnormal, switching is needed, and after the temperature information of the standby path equipment is compared, the standby path equipment with normal temperature change is automatically selected, so that the technical effect of ensuring stable signal transmission is achieved.
