Outdoor state monitoring equipment and system of frequency shift pulse track circuit

Abstract

The invention provides outdoor state monitoring equipment and system of a frequency shift pulse track circuit. The equipment comprises a choke transformer, an acquisition sensor and an acquisition extension machine which are arranged in the same box body. The acquisition sensor acquires the outdoor state of the frequency shift pulse track circuit to obtain an acquisition signal, and sends the acquisition signal to an acquisition extension machine, the acquisition extension machine processes the acquisition signal to obtain communication data, and the communication data are sent to a collectiondevice through a cable in a power carrier communication mode. According to the scheme, the acquisition sensor is arranged on a preset acquisition point to acquire the data of outdoor equipment of thefrequency shift pulse track circuit, and the acquired data are processed and transmitted through the acquisition extension machine, so that the operation state of the outdoor equipment of the frequency shift pulse track circuit can be known in real time, the sudden failure point can be located in time, the influence range of the failure can be prevented from being increased, the failure maintenance time can be shortened, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of circuit monitoring, in particular to an outdoor state monitoring device and system for a frequency shift pulse track circuit. Background technique [0002] With the development of science and technology, track circuit technology is widely used in various lines of national railway lines. Because the environment of the track circuit is easy to send and change, the track circuit is prone to changes such as changes in the environment of the track bed, loose connecting wires, loose plugs, Insulation damage or rail corrosion and other problems will cause sudden failures such as burning insulation failure or "red light belt", which will cause safety problems in train running. [0003] In order to ensure the safe operation of the train, it is necessary to monitor the running status of the track circuit. At present, the distribution of the traction current in the traction return equipment is monitored by the self...
