Abstract

The utility model relates to a ramp alcohol automatic detection device. The ramp alcohol automatic detection device comprises a single chip microcomputer, an alcohol concentration tester, a digital to analog converter, a single chip microcomputer, a display, an input device, a buzzer, a signal processor and a relay K. An alcohol sensor collects exhaled gas, and sends a signal to the single chip microcomputer. The single chip microcomputer carries out processing and analysis, and displays a result. Through the input device, different thresholds are set. If the detected alcohol concentration exceeds a set threshold, the single chip microcomputer can control the buzzer, and at the same time outputs a signal. The processed signal is converted into a signal which controls a coil of the relay K. A normally open contact of the relay K is used as a condition of controlling the lifting of a ramp railing. According to the utility model, a drunk driver can be effectively prevented from going in and out of a housing estate, a school or other places; accidents caused by drunk driving can be prevented; and pedestrians and public facilities can be protected.

Description

Ring road mouth alcohol automatic detection device

Technical field

The utility model relates to a kind of ring road mouth alcohol automatic detection device.

Background technology

Country is very large to the inspection of driving when intoxicated now, the mode that checks drunk driving now is still mainly set up the outpost of the tax office to come an automobile-used hand-held alcohol detector to carry out alcohol-detection to driver in a certain section by traffic police, such detection mode has certain drawback, the manpower that primary need is more, second can cause and must affect traffic, and the 3rd does not have the section checking likely to have fish that has escape the net.

Utility model content

The purpose of this utility model is to solve the problems of the technologies described above, thereby a kind of ring road mouth alcohol automatic detection device is provided.

The technical scheme that the utility model addresses the above problem is as follows:

Ring road mouth alcohol automatic detection device, comprise single-chip microcomputer, tester for alcohol concentration, digital to analog converter, single-chip microcomputer, display, input equipment, hummer, signal processor, relay K, described alcohol sensor gathers the gas signal that testee breathes out, and by described digital to analog converter, convert simulating signal to digital signal and deliver to described single-chip microcomputer, single-chip microcomputer carries out analyzing and processing to digital signal, and the result of gained is shown by described display; The different threshold values of alcohol concentration under varying environment are set by input equipment, if detected alcohol concentration has surpassed the threshold values setting, single-chip microcomputer just can be controlled the warning of sounding of described hummer so, described single-chip microcomputer is also exported a signal simultaneously, this signal is converted into the signal of the coil of controlling described relay K after treatment, and the normally opened contact of relay K is as the condition of controlling the lifting of circle crossing gate.

As technique scheme preferably, described input equipment is keyboard.

The utlity model has following beneficial effect:

The utility model control core is single-chip microcomputer, by alcohol sensor, as detection means, after the conversion of A/D signal, signal is transmitted to a single-chip microcomputer, and single-chip microcomputer is exported to circle crossing gate control system and warning system signal after routine processes.At every place, automatic sluice gate is installed this device, vehicle drive personnel to the sluice gate of coming in and going out carry out drunk driving detection, if alcohol content surpasses the range detection device of regulation, can send alerting signal, signal is sent to sluice gate simultaneously and control railing, not allow automobile sail into or roll away from; If alcohol content is no more than the range detection device of regulation, just can not send signal, sluice gate railing can normally rise; Therefore, the utility model can effectively prevent that drunk driving person from passing in and out community, school or other places, can prevent because the generation that drunk driving causes the accident can play a very good protection to pedestrian, communal facility.

Embodiment

Below in conjunction with accompanying drawing, the utility model is further detailed.

This embodiment is only to explanation of the present utility model, is not to restriction of the present utility model.Any modification that those skilled in the art have done after having read instructions of the present utility model, as long as in the protection domain of claims, all will be subject to the protection of Patent Law.

As shown in Figure 1, single-chip microcomputer tester for alcohol concentration gathers gas signal with alcohol sensor, and by digital to analog converter, convert simulating signal to digital signal and deliver to single-chip microcomputer (as Fig. 2), single-chip microcomputer carries out analyzing and processing (as Fig. 3) to digital signal, and the result of gained is shown, the different threshold values of alcohol concentration under varying environment can be set by keyboard, if detected alcohol concentration has surpassed the threshold values setting, single-chip microcomputer just can be controlled the hummer warning (as Fig. 4) of sounding so, single-chip microcomputer is also exported a signal simultaneously, this signal is converted into the coil (as Fig. 5) of pilot relay K after treatment, the normally opened contact of relay K is as the condition of controlling the lifting of circle crossing gate.If vehicles passing in and out human pilot does not have the normally lifting of overproof railing over there, if alcohol surpasses setting value just normally lifting of railing over there.

Claims

1. ring road mouth alcohol automatic detection device, it is characterized in that: comprise single-chip microcomputer, tester for alcohol concentration, digital to analog converter, single-chip microcomputer, display, input equipment, hummer, signal processor, relay K, described alcohol sensor gathers the gas signal that testee breathes out, and by described digital to analog converter, convert simulating signal to digital signal and deliver to described single-chip microcomputer, single-chip microcomputer carries out analyzing and processing to digital signal, and the result of gained is shown by described display; The different threshold values of alcohol concentration under varying environment are set by input equipment, if detected alcohol concentration has surpassed the threshold values setting, single-chip microcomputer just can be controlled the warning of sounding of described hummer so, described single-chip microcomputer is also exported a signal simultaneously, this signal is converted into the signal of the coil of controlling described relay K after treatment, and the normally opened contact of relay K is as the condition of controlling the lifting of circle crossing gate.
