Description

technical field [0001] The invention belongs to the technical field of rail transit, and in particular relates to an all-electronic asymmetric high-voltage pulse rail circuit system and a method for using the same. Background technique [0002] The track circuit is a circuit composed of rail lines and rail insulation. It is the most commonly used method for monitoring the occupancy of trains in sections or trains and shunting cars in stations. The asymmetrical high-voltage pulse track circuit utilizes its characteristics of large instantaneous power and high instantaneous current of the shunt to improve and solve the bad effect of the track circuit shunt. However, the asymmetric high-voltage pulse track circuit currently used has a single function, and the receiving end is realized by an analog circuit. In a symmetrical high-voltage pulse track circuit, one pulse signal receiver can only analyze one signal. When the receiving end has two or three receivers, it is necessary...

Problems solved by technology

However, the asymmetric high-voltage pulse track circuit currently used has a single function, and the receiving end is realized by an analog circuit. In a symmetrical high-voltage pulse track circuit, one pulse signal receiver can only analyze one signal. When the receiving end has two or three receivers, it is necessary to increase the number of pulse signal receivers, which increases the circuit cost and is inconvenient to use.
