The invention discloses a signal machine red light control system under interlocking application, comprising an A-series signal light control unit, a B-series signal light control unit and a switching unit, the switching unit is used to control the A-series signal light control unit, the B-series signal light control unit The control unit realizes active / standby switching, and the A-series signal light control unit and the B-series signal light control unit both include: a red light driver board, used for output control of red light signals; a signal light driver board, used for other colored lights other than red lights Signal output control; the safety control board sends the red light lighting control signal to the red light driver board; the safety power board cuts off the safety power output when the system fails. The technical solution adopted by the present invention ensures that the red light is normally lit during the system startup process and the system failure, and there is a combination logic relationship between the red light and other color lights, ensuring that as long as the system has power supply, the other color lights are not lit Under this condition, the red light is always on, which improves the system security.
Description
technical field [0001] The invention belongs to the technical field of rail transit, and in particular relates to the control technology of signal lamps of trackside signal machines. Background technique [0002] The signal machine is the key trackside equipment of railway and urban rail transit, and it is an important facility to transmit whether the train is allowed to pass in the track section to the driver. In the railway signal system with ground signal as the main signal, the driver must decide whether the vehicle is passing according to the display status of the signal machine. The signal colors of the signal machine are divided into red, yellow, green, blue, and moon white. The red light means that trains are not allowed to pass the signal machine. The correct display of the signal machine is the basis for ensuring the safe operation of the train. Light color signal lights are particularly critical. [0003] The control of the trackside signal is mainly undertaken ...
