The detection device comprises a track signal quality measurement unit of a first structure measures track circuit signal current, carrier frequency and low frequency; a control unit for controlling the track signal quality measurement unit to measure the track circuit signal current, carrier frequency and low frequency, and communicating witha data server through a wireless communication unit; a track signal quality measurement unit of the second structure is same as the first structure; and a control unit for controlling the track signal quality measurement unit to measure the track circuit signal current, carrier frequency and low frequency, and performing Bluetooth communication with a general smart phone by taking a Bluetooth module as a transfer station. The detection device disclosed by the invention has the advantages of being simple in operation, and small in measurement repeatability error.

Description

technical field [0001] The invention relates to a track circuit signal quality detection technology. Background technique [0002] The track circuit is a circuit formed by using the rail of a section of railway line as a conductor. It is used to monitor the occupancy of the line, check the integrity of the rail, and also to transmit driving information. For example, the automatic blocking equipment uses the track circuit to transmit frequency-shifted signals of different frequency information. It determines the display of the signal machine, and then determines the target speed of the train, thereby controlling the train operation; the track circuit is the basic equipment of the train operation control system, and the quality of the signal transmitted in the rail directly determines the driving safety and transportation efficiency. [0003] At present, the signal quality detection of the track circuit usually uses a multimeter or a current clamp coupling method to measure; t...
