Embodiment Construction
[0041] The specific implementation manner of this embodiment will be described below in conjunction with the accompanying drawings.
[0042] The platform door equipment in this embodiment is composed of three platform doors, and each platform door is equipped with a travel switch for detecting the opening and closing status of the platform door, and each travel switch is equipped with a detection indicator for the fault position of the safety circuit of the platform door system device. The detection and indicating device for the safety circuit fault position of the platform door system specifically includes a safety circuit fault detection circuit and a platform door indicator light control circuit.
[0043] Each platform door system safety circuit fault location detection indicator device is equipped with an MCU, the present embodiment uses the ST company's STM32F103RCT6 chip as the MCU, the MCU has a CAN communication interface, can communicate with the host computer, the de...

The invention a detection indication device and method for a safety loop fault position of a platform door system, and belongs to the field of rail traffic platform door safety loop detection. A light-emitting end of a first photocoupler and a current-limiting resistor are connected in series to form a fault position detection circuit, a light receiving end of the first photocoupler is connected with a processor, the processor is connected with a coil of a dual-contact relay in a control way, a normally-open static contact of the dual-contact relay is used for connecting with ground, a movablecontact and a normally-closed contact of the dual-contact relay are used for being connected in series with a platform door indication lamp DCU control circuit, a light receiving end of a second photocoupler is connected with the processor, and a light-emitting end of the second photocoupler is used for being connected in series with the platform door indication lamp DCU control circuit. The detection indication device is simple in structure and is convenient to additionally arrange, a site platform person is rapidly noticed with a safety loop fault generation position after a safety loop fault is rapidly and effectively identified, and the fault detection efficiency and reliability of existing line platform door equipment is effectively improved.
Description
technical field [0001] The invention relates to a detection and indication device and method for a safety loop fault position of a platform door system, and belongs to the field of detection of a safety loop of a rail transit platform door. Background technique [0002] The platform door safety circuit, also known as the platform door closing and locking circuit, is composed of hard wires in series for each sliding door and each detection switch of the emergency door. When all sliding doors on the platform are completely closed and locked, the detection switches of all sliding doors and emergency doors are connected, the safety circuit is turned on, and the subway train can enter or depart safely. If any sliding door or emergency door is not completely closed lock, the corresponding detection switch is opened, the safety circuit is disconnected, and the signal system cannot detect the safety circuit signal of the screen door system. The station personnel operate the "interl...
