The invention discloses a safety control system for the door of a bus, comprising a power supply system, a central processor, a frequency signal shaping and amplifying circuit and an execution system, wherein the frequency signal shaping and amplifying circuit comprises a diode D1; the execution system comprises a triode Q2 and a relay K1; the normally-closed contact ports Port 1 and Port 2 of the relay K1 are connected to a door opening and closing device and a power connection line for ensuring the normal working of the door opening and closing device in series; when the frequency of the signal sent by a speed sensor connected with the positive terminal of the diode D1 in the frequency signal shaping and amplifying circuit is greater than 45 Hz, the central processor sends a programmed instruction signal after being processed and recognized by internal arithmetic, and an output port PB4 outputs a high level; after the execution system receives the instruction, the triode Q2 is switched on, the relay K1 works, and the normally-closed contact ports Port 1 and Port 2 of the relay are cut off; at the moment, the door opening and closing device is powered off, so that the door cannotbe opened; when the bus stops or has a low speed, the signal frequency is less than 45 Hz, and the execution system enables the door opening and closing device to be powered on, so that the door can be normally opened and closed.
Description
Technical field [0001] The invention relates to a safety control system for a passenger car door. Background technique [0002] The doors provided on the existing ordinary passenger cars can be opened at any time during parking and driving. In the prior art, the vehicle door is usually opened and closed through a vehicle door opening and closing device, and the vehicle door opening and closing device is connected with a power supply to ensure its normal operation. If the driver makes a mistake in the operation of the passenger car to open the door during high-speed driving, it will seriously affect the safety of passengers' personal and property. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a passenger car door safety control system, which can ensure that the passenger car cannot open the door during high-speed driving, and can also ensure that the passenger car can normally open the door when it is parked and...
