The present invention provides a method for transmitting the electric power data of a rail includes collecting electrical current analog signals from a conductor rail and transmitting the electrical current analog signals to a processing module; converting the electrical current analog signals into electrical current digital signals through the processing module; transmitting the electrical current digital signals to a monitoring platform through a wireless communication module. The electrical current information of the conductor rail is collected by an electric current sensor installed on a cable, which is connected to the conductor rail. The electrical current information collected by the electric current sensor is transmitted to the processing module after pre-processing comprising signal amplification and filtering. The present method effectively prevents problems of high bit error rates and faults with a negative impact on the data transmission with data message corrupted by noise during transmission.
