Problems solved by technology

However, it can only be carried out by the traffic police officers holding the breath alcohol tester to detect the drivers one by one, which is a waste of police force and inconvenient, and cannot solve this kind of problem from the root cause, so drunk driving incidents still happen from time to time

Embodiment 1

[0037] Such as figure 1 as shown, figure 1 It is one of the schematic flow charts of the detection method of the embodiment of the present invention. The invention provides a safety detection method for preventing drunk driving of a vehicle, the safety detection method comprising:

[0038] 110. Obtain the gas information blown by the user into the collection device;

[0039] 120. Determine whether the gas information exceeds a preset threshold;

[0040] If so, disconnect the power supply of the fuel pump;

[0041] If not, close the fuel pump power supply.

[0042] The vehicle safety detection method for preventing alcohol driving in the embodiment of the present invention is implemented based on the vehicle safety detection system for preventing alcohol driving. It is necessary to find out the control power line of the vehicle fuel pump, then cut off the control power line of the fuel pump, connect the second relay inside the vehicle anti-drinking driving safety detection...

Embodiment 2

[0049] Such as figure 2 as shown, figure 2 It is the second schematic flow diagram of the detection method of the embodiment of the present invention. On the basis of Embodiment 1, the gas information in this embodiment includes: the alcohol concentration of the gas and the air pressure of the gas;

[0050] When the gas information is the alcohol concentration of the gas, it is judged whether the alcohol concentration of the gas exceeds a preset alcohol concentration value;

[0051] When the gas information is the air pressure of the gas, it is determined whether the air pressure of the gas exceeds a preset air pressure value.

[0052] The vehicle anti-drinking driving safety detection system of the embodiment of the present invention uses a signal acquisition device composed of a pressure sensor and an MQ-3 alcohol concentration sensor. Before starting the vehicle, the user must blow air on the acquisition device with his mouth. When there is an air pressure of 0-10Kpa W...

Embodiment 3

[0056] On the basis of Example 2, the preset alcohol concentration value of this embodiment is 0.4mg / L, and the value range of the preset air pressure value is 0-10Kpa. Among them, 0.4mg / L is consistent with the alcohol detection standard of the traffic police.

[0057] A pressure sensor is installed inside the gas collection device, and the user is forced to take an active alcohol concentration test before each start of the vehicle. The user must blow 10KPa gas pressure into the collection device to allow the vehicle to connect to the fuel pump relay. The MQ-3 alcohol concentration sensor technology is used to detect the user's alcohol content and determine whether it belongs to drunk driving. If the alcohol concentration exceeds 0.4mg / L, the system will disconnect the fuel pump relay circuit.

[0058] The preset alcohol concentration value is 0.4mg / L. When the alcohol concentration value of the gas inhaled by the user is greater than 0.4mg / L, it means that the user has drun...

Abstract

The invention provides a safety detection method and system for preventing drunk driving of a vehicle. The safety detection method comprises the steps that information of gas blown into collecting equipment by a user is obtained; whether the gas information exceeds the preset threshold value or not is judged; if the gas information exceeds the preset threshold value, a power supply of a fuel pumpis disconnected; and if the gas information does not exceed the preset threshold value, the power supply of the fuel pump is connected. According to the user gas information obtained by the collectingequipment, a relay of the fuel pump of the vehicle is controlled, before the vehicle is started by the user, the safety detection system for preventing drunk driving of the vehicle forces to ask theuser to actively being subjected to an alcohol concentration test, and when the user passes the alcohol test, the safety detection system for preventing drunk driving of the vehicle can allow the userto start the vehicle. Otherwise, the relay of the fuel pump of the vehicle is controlled to be disconnected with the power supply of the fuel pump, and the vehicle cannot be started, so that a drunkdriving detection mode is changed into vehicle monitoring and user active test instead of a previous mode of traffic police checking a drunk driving behavior, the working difficult of checking and treating drunk driving by traffic polices is reduced, and investment of social manpower and material resources in traffic maintenance work is reduced.

Description

technical field [0001] The invention relates to the field of traffic safety management, in particular to a safety detection method and system for preventing drunk driving of vehicles. Background technique [0002] In recent years, many traffic accidents caused by drunk driving have greatly endangered the safety of people's lives and property. Whether the person has consumed alcohol. There are many types of police alcohol testers on the market, with powerful functions and high sensitivity. But it can only be carried out by the traffic police officers holding the breath alcohol tester to detect the drivers one by one, which is a waste of police force and inconvenient, and can not solve this type of problem from the root cause, so drunk driving incidents still occur from time to time. [0003] Among the existing technologies, the alcohol content of the driver can only be tested by the traffic police. If the alcohol content exceeds the standard, the traffic police can only for...
