The processing unit may use run-length coding algorithm to compress the digital signal to be stored to obtain several compressed digital signal frames. Under different conditions of data link, transmission of compressed digital signal frames is adjustable to improve the reliability of digital signal transmission.

Abstract: A method for inspecting a traction power network is provided based on a platform which includes a device body of an inspection device for a traction power network apparatus. A power switch is disposed on an outer surface of the device body near a front end thereof, in which a sensitive galvanometer is disposed on the power switch. One end of the sensitive galvanometer is fixedly connected to a temperature sensor coupled to a controller. The controller is coupled to a 4G first communication module coupled to a 4G network. The 4G network is coupled to a processing platform coupled to the 4G network through a 4G second communication module. Other methods and structures are combined to avoid deficiencies in the prior art, such as poor speed and long time in the temperature signal transmission and avoid a controller without meeting requirements for efficient and timely temperature signal transmission.
