Abstract

The invention provides a small track state control circuit and a driving method thereof. The small track state control circuit comprises a power source, a main control system, a power supply control circuit and a small track state receiver. The power source is used for providing a supply voltage. The main control system is used for judging whether the direction of a section needs to be changed according to an interlocking direct change command and track section state information, and generating and sending an on-off control signal when judging that the direction of the section needs to be changed. The power supply control circuit is electrically connected with the power source and the main control system, respectively, for receiving the on-off control signal and turning on according to theon-off control signal, so that the power source is electrically connected with the small track state receiver to provide the supply voltage for the small track state receiver. The small track state receiver is electrically connected with the power supply control circuit to receive the supply voltage through the power supply control circuit during the direction change of the section, and generatea current rail section emptying prompt signal.

Description

technical field [0001] The invention relates to the technical field of railway electrical signals, in particular to a small rail state control circuit and a driving method thereof. Background technique [0002] The ZPW-2000A small rail state control circuit equipment is used in most of the track sections of the automatic blocking line. This type of small rail state control circuit equipment has system reaction time from no code to code, so when the section is changed, the second track section outside the departure gate and the boundary section are prone to small rail flashing red. When changing from forward direction to reverse direction, since the reverse direction is blocked between stations, the red light belt of the small rail will affect the outer section of the exit of the departure station, thereby affecting the opening of the departure signal. [0003] At present, the method of adding resistance-capacitance boxes is generally used for the flashing red sections of th...
