Safe intelligent parking braking device
Technical Field
The invention relates to the field of road traffic safety, in particular to a safe and intelligent parking brake device for preventing drunk driving and preventing illegal behaviors of driving without fastening a safety belt.
Background
At present, behaviors of drunk driving, drunk driving and driving without fastening a safety belt can only be limited by the conscious of a driver and the inspection of traffic policemen, a large amount of police force and financial resources are wasted, the effect is not good, illegal behaviors of drunk driving and drunk driving can be shot by monitoring at an intersection, but illegal behaviors of drunk driving and drunk driving cannot be shot, and the illegal behaviors have great potential safety hazards and dangerousness, so that a safe and intelligent device which can thoroughly prevent illegal behaviors of drunk driving and safety belt fastening which violate 'road traffic safety law' is urgently needed.
Disclosure of Invention
In view of the above circumstances, an object of the present invention is to provide a safe and intelligent parking brake device capable of quickly preventing the occurrence of drunk driving, and seatbelt unfastening driving behaviors.
The invention installs an electromagnetic switch under the traditional parking brake, so long as the electromagnetic coil (22) loses power, the iron rod (29) in the interior can be instantly popped to prop against the parking brake lever (26), thereby the parking brake cannot be laid flat. The safety belt buckle (23), the electromagnetic coil (22), the relay normally-open point (25) and the 12V power supply (24) form a loop. The alcohol detection circuit is by 89C51 singlechip (1) as the master controller, still includes: a reset circuit: a reset button (3), a 10K omega resistor (4) and a 10Uf capacitor (5); an alcohol sensor (6); an oscillation circuit: a 22pf capacitor (10) and an 11.592MHz crystal oscillator (11); a 12V-to-5V circuit (2); a relay drive circuit: a 4.7K omega resistor (19), a relay coil (17), a diode (18), a 12V power supply (24) and a triode; buzzer drive circuit: 1K omega resistance (20), buzzer (21), triode. When alcohol sensor (6) detected that the gas that the driver exhaled contained the alcohol molecule, during signal afferent 89C51 singlechip (1), the singlechip output low level can lead to relay coil (17) to lose electricity, and relay normal open point (25) can't be closed to make solenoid (22) lose electricity. When the safety belt is not fastened, namely the safety belt buckle (23) is not closed, the circuit is opened, and the electromagnetic coil (22) is also powered off.
