Problems solved by technology

However, due to the complex lines of stations and freight yards, it is impossible to realize locomotive signal display through track reception.
If the code technology in the station is realized, it will be necessary to carry out a large number of transformations on the signal equipment of the station. Both the amount of work and the investment are considerable, and it cannot be realized under the current conditions.

Abstract

The invention relates to a passive ground sensor for a railway shunting monitoring system. A complete machine circuit is composed of 2 rectification filter circuits, 2 relays and 3 radio circuits. Each radio circuit is formed by connecting an identity card (ID) storage chip and an inductance-capacitance (LC) oscillating circuit, the input end of a rectification filter circuit A is connected with a current transformer L1, and the output end of the rectification filter circuit A is connected with a coil of a relay J1; and the input end of a rectification filter circuit B is connected with a current transformer L2, and the output end of the rectification filter circuit B is connected with a coil of a relay J2. The passive ground sensor is arranged on a signal receiving device of the passive ground signal sensor and a locomotive, not only changes no line signal, but also enables signals to be accurately transmitted to signal receiving equipment of the locomotive, and enables the monitoring system to stably and reliably work. The ground sensor does not emit electromagnetic waves initiatively, thereby being free of electromagnetism pollution on the environment.

Description

technical field [0001] The invention relates to a ground shunting signal detection device of a railway shunting monitoring system, in particular to a passive ground sensor used in the railway shunting monitoring system. Background technique [0002] At present, the train operation monitoring and recording device has been widely used in the locomotive system of the whole railway, which greatly improves the safety factor of locomotive operation. Realized the purpose of efficient, fast and safe railway transportation. However, at present, in the process of shunting operations and locomotives entering and leaving the warehouse, due to the limitation of the track circuit conditions in the station yard, the ground shunting signal and the locomotive train operation monitoring and recording device cannot be chained to implement safety control, which has become a safety production aspect of relevant railway departments. Problems to be solved. During the shunting operation, ...
