Abstract

The device for preventing driver from driving after drinking is a device which is suitable for preventing the drivers from driving various trucks with electrical starting, oil brake or air brake, cars and tractors with cabs after drinking. The utility model is composed of gas sensors, electrical apparatus elements and machine parts. The output part of the electronic circuit controls a main electric power source, an acoustic horn loop and a brake system. When the human pilot enters the driving room after drinking, the QM output end of the gas sensor of the electronic circuit exports electrical signals. The main electric power source of the system can be cut by the other elements, at the same time the acoustic horn and the brake system are switched on. The accident can be stopped because of the alarm of the acoustic horn and the braking of the brake system.

Description

Device for preventing driver from driving after drinking

The invention belongs to transport vehicle safety traffic device

The transport vehicle that travels is not now all installed anti-crane device after drinking, causes the navigating mate of the navigating mate, particularly highway transport vehicle of some vehicles, and the back driving causes the accident because of drinking.

The objective of the invention is, a kind of device is provided, be installed on the transport vehicle, when the navigating mate of vehicle was drunk the back driving, this device can cut off the power supply of vehicle using electricity system automatically.The ring loudspeaker are reported to the police, and self-actuating brake, and the accident of stopping takes place.

Below in conjunction with accompanying drawing, technical characterictic of the present invention is described:

Fig. 1, be power supply of the present invention reason scheme drawing;

Fig. 2, be implementation column principle schematic of the present invention;

Fig. 3, be block scheme of the present invention.

In the power supply reason scheme drawing as Fig. 1, which comprises at least a Qm, resistance R by gas sensor ₁, R ₃Variable resistance W and push switch K ₂The detection loop that constitutes of long closed contact; The selection utmost point, resistance R by variable resistance W ₂, capacitor C ₂, transistor T ₁T ₂, the sampling control loop that constitutes of relay j; Contact, electromagnet DT by relay j.The actuating system that dynamic loud-speaker Y constitutes; By diode D ₁, capacitor C ₃The protective circuit and the capacitor C that constitute ₁, the voltage regulation filtering loop that constitutes of stabilivolt DW.Among Fig. 1, K ₁It is the existing key switch of vehicle; K ₂It is hand switch; Press K ₂, this device is inoperative; K ₃It is the original dynamic loud-speaker push switch of vehicle; A point among Fig. 1 connects the storage battery of vehicle, and the B point connects the vehicle using electricity system.As implement shown in the illustration 2, it is indoor that 1. the sensor gas sensor is installed in vehicular drive, and 2. electromagnet is installed in the brake system of vehicle, and other element can fit together, and is contained in the control capsule KZH.Be installed in the appropriate location of vehicle, press the mode of connection of Fig. 2,3. all units, device are connected with lead and feeder line.

Connection mode according to Fig. 1 illustrates that principle of work of the present invention is as follows:

Under the normal circumstances, navigating mate inserts key, connects K ₁, the gas sensor that detects the loop does not have electric signal output; Transistor T in the sampling control loop ₁, T ₂Be in off condition, the normally closed contact j of relay j _-1Connect the using electricity system of vehicle, its open contact j _-2, j _-4Disconnect, electromagnet DT does not work, and dynamic loud-speaker Y does not report to the police, and starting vehicle can travel, and enters operator's compartment after navigating mate is drunk, if connect K ₁When concentration of ethanol reached certain value in the operator's compartment in back very short time, Qm converted detected ethanol signal to electric signal output, after the W sampling, passes through R ₂To T ₁Base stage make T ₁Conducting.T ₁, T ₂Be emitter follower, thereby T ₂Also conducting, the j action, its normally closed contact disconnects, and cuts off the power supply of vehicle using electricity system; Its open contact closure.Connecting Y reports to the police; Connect the DT self-actuating brake; Connect K if enter operator's compartment after navigating mate is drunk ₁During concentration of ethanol out of reach certain value, Qm can not export electric signal at once in short time.Other yuan, device also are failure to actuate, and start vehicle, can travel; But work as concentration of ethanol once reach one regularly, Qm just exports electric signal, and other yuan, device principle of work are as mentioned above.Thereby realized the present invention's purpose.

Fig. 3 is a block scheme of the present invention, the test section be equivalent among Fig. 2 gas sensor 1., control part is equivalent to control capsule KZH among Fig. 2, operating part be equivalent among Fig. 2 electromagnet 2., dynamic loud-speaker Y.Direction indication be equivalent among Fig. 2 feeder line 3..

The present invention has following characteristics:

1, satisfying under the condition of the present invention. The element that this device is selected is few, thus simple in structure, reliability is high, cost is low;

2, this device is installed, is not changed the structure of vehicle;

3, this device is installed after, do not influence any performance of vehicle.

The present invention is mainly used in and prevents to start with electricity.Driving after the navigating mate of the trac. of the various autotrucies of oil brake or pneumatic brake, car and band operator's compartment is drunk.For reliability and the sensitivity that improves device, can adopt a plurality of detection gas sensors.

Claims

1, anti-crane device after drinking is characterized in that: this device comprises with gas sensor 1. as gas, the test section of electricity conversion; With the control part of control capsule KzH as control; With electromagnet 2., operating part that dynamic loud-speaker Y reports to the police as stop and the feeder line that connects them 3., make when 1. the test section detects the smell of ethanol that by control part KzH, 2. operating part reaches Y and cut off the power supply automatically, brake, report to the police.

2, by the described device of claim 1, it is characterized in that: 1. the test section has a gas sensor at least.
