In view of China's current policies for the 450-470 MHz frequency band,this paper explains the current operation situation of the 450 MHz wireless train dispatching communication system and the necessity of conducting dynamic inspection for the existing in-use equipment.After an introduction to the 450 MHz wireless train dispatching communication system and the starting mode of dynamic inspection of wireless field strength,it studies the operation method of dynamic inspection for wireless train dispatching communication system,and proposes a dynamic inspection system for the 450 MHz wireless train dispatching communication system.In view of the shortcomings of the current starting mechanism for field strength testing,it provides optimization suggestions for the inspection system.
