Abstract
The utility model discloses a vehicle-mounted alcohol detector and belongs to an exhaled air content detector. The vehicle-mounted alcohol detector comprises a central processing module and an analog to digital (AD) conversion module, a power module, a display module, a keyboard module, a positioning module, an alarming module and a general packet radio service (GPRS) module which are connected with the central processing module, wherein an alcohol concentration acquisition module is connected to the AD conversion module. The vehicle-mounted alcohol detector is rational in structural design and ingenious and novel in concept; an MQ-3 air sensor acquires alcohol concentration information, so that an alcohol detection overproof result is directly transmitted to a mobile phone of a law enforcement officer through a GPRS wireless technology; and the position of a vehicle of a driver with overhigh alcohol concentration can be fixed through a global positioning system (GPS) positioning technology, so that a traffic police can stop the vehicle and check whether a driver is in drunk driving. The conventional mode that the law enforcement officer checks the alcohol concentration with handheld equipment is simplified, and the law enforcement efficiency is greatly improved; and the vehicle-mounted alcohol detector is extremely high in practicability, low in manufacturing cost and favorable for large-scale popularization and application.
Description
Technical field:
The utility model belongs to the alcoholicity of exhaled gas detector, is specifically related to the vehicle-mounted alcohol detector.
Background technology:
Modern society, traffic is flourishing day by day, and automobile has become the requisite vehicles; Automobile is when offering convenience to us, brought hidden danger safely also for our trip, the phenomenon of drink-driving is particularly outstanding, and becomes first " killer " of traffic hazard, and alcohol content tester has become the traffic administration personnel and detected the indispensable instrument of driving when intoxicated.Existing alcohol content tester mainly is handheld device, need tackle the vehicle that travels during inspection, and cause quarrel between the police and the people through regular meeting, has brought many inconvenience to the law enfrocement official, has had a strong impact on work efficiency, also causes bigger difficulty to law enforcement.On the other hand, many vehicles all are equipped with the GPS location navigation, but fail to external world's transmission navigation information.Based on this, a kind of more science, detector easily are badly in need of in traffic control department, and the function of plurality of devices is better combined, and improve the traffic safety way to manage, with the serious day by day urban transport problems of reply, realize the intelligent management of traffic.
The utility model content:
The purpose of this utility model is in order to overcome the weak point that above-mentioned prior art exists, and a kind of vehicle-mounted alcohol detector is provided, and has solved the difficult problem that traffic police's pushing-off the wagons is traced the inconvenience of drunk driving, and it is simple in structure, easy to use, is easy to large-scale promotion application.
The technical solution adopted in the utility model is: this vehicle-mounted alcohol detector, comprise central processing module, and the AD modular converter that is connected with central processing module, power module, display module, Keysheet module, locating module, alarm module and GPRS module, be connected with the alcohol concentration acquisition module on the described AD modular converter.
Described alcohol concentration acquisition module is the MQ-3 gas sensor.
Described alarm module comprises voice module, the preposition expander of loudspeaker, speaker drive circuit, oscillator and storage module.
Described central processing module is single-chip microcomputer.
The beneficial effects of the utility model are: reasonable in design, novelty is skillfully constructed, gather alcohol concentration information by the MQ-3 gas sensor, the result that alcohol detection is exceeded standard directly is sent in law enfrocement official's mobile phone by the GPRS wireless technology, but also can be by the position of the too high vehicle of GPS location technology locking alcohol concentration, be convenient to traffic police's pushing-off the wagons and check whether drunk driving.With traditional being oversimplified by law enfrocement official's handheld device inquiry alcohol concentration, improved law enforcement efficiency greatly.And having very strong practicality, low cost of manufacture is easy to large-scale promotion application.
