Barrier gate car-smashing prevention control circuit

Abstract

The invention discloses an anti-smashing vehicle control circuit of a barrier gate, comprising: a limit switch for detecting the switch state of the lifting rod of the barrier gate; an anti-smashing ground sense for detecting whether a vehicle is pressed in; a pressure wave switch, It is installed on the lifting rod of the barrier gate to detect the pressure wave signal; the main control MCU is used to receive the output signals of the limit switch, anti-smashing ground sense, and pressure wave switch, and generate software switch signals to output to the logic circuit; logic The circuit is used to generate the anti-smashing car control signal under the control of the limit switch, the anti-smashing sense, the pressure wave switch and the signal output by the main control MCU; the driving circuit is used for the anti-smashing car control signal output by the logic circuit Under the control of driving the lift bar of the barrier gate to lift and fall, the present invention can solve the problem that the software anti-smashing control process may be unstable due to software failures such as program runaway or crash in the prior art. The problem of smashing function failure.

Description

technical field [0001] The present invention relates to a control circuit, in particular to an anti-smashing car control circuit for a barricade gate hardware in a parking lot. Background technique [0002] With the increasing number of motor vehicles in the city, there are more and more barrier gates used for parking lot access management. In addition to the requirement of fast switching and reliable operation of the barrier gate, it is also the most basic requirement that the barrier gate itself has the vehicle anti-smashing function. [0003] At present, most of the barrier gates that realize the anti-smashing function in the market are detected by sensors such as anti-smashing ground sense, and the anti-smashing function of the vehicle is realized through the software logic of the single-chip microcomputer or microprocessor. For this software anti-smashing technology, if in When the single-chip microcomputer or microprocessor causes the program to run away or crash due ...
