Abstract
The utility model discloses an overspeed alarm system based on a single chip microcomputer. The overspeed alarm system comprises a vehicle speed sensor, an analog to digital (A\D) converter, a micro control chip, a liquid crystal display and a buzzer, wherein the vehicle speed sensor is connected with the micro control chip through the A\D converter, and the liquid crystal display and the buzzer are connected on the micro control chip. The overspeed alarm system simply improves existing automobile equipment to give out alarm when an automobile is overspeed to prompt a driver to drive safely.
Description
Technical field:
The utility model relates to a kind of automobile at the running on expressway Overspeed Alarm System, especially a kind of SCM Based Overspeed Alarm System.
Background technology:
Fast development along with Chinese national economy, express highway constantly perfect, road conditions is become better and better, automobile is also more and more faster in the speed of running on expressway thereupon, although relevant departments always emphasize to drive over the speed limit, but chaufeur be can't help when road conditions are good, the custom of stepping on the gas is just arranged, so be easy to cause the traffic accident caused because of hypervelocity.
The utility model for the problems referred to above developed a set of when automobile when running on expressway exceeds the speed limit, system that can automatic alarm, remind the chaufeur Reduced Speed Now.
The utility model content:
The purpose of this utility model is, proposes a kind of Overspeed Alarm System, by the automobile existing installation is simply transformed, just can realize will giving the alarm when driving over the speed limit when automobile, reminds driver safety to travel.
Basic functional principle of the present utility model: when automobile travels on road, speed sensor is passed to the microcontroller chip by electronic signal, the microcontroller chip judges whether the automobile current driving speed of a motor vehicle has surpassed the restriction maximum speed, if surpassing, current vehicle speed limits maximum speed, the microcontroller chip will be controlled the sound that buzzer phone sends warning, and the liquid crystal display screen display " vehicle that you drive is with hypervelocity, please slow down and go slowly " printed words, if current vehicle speed surpasses restriction, maximum speed continues more than one minute, the microcontroller chip will be controlled buzzer phone and continue to send alarm sound, and record current time on LCDs, current vehicle speed, the hypervelocity time length.
In order to achieve the above object, the utility model adopts following technical solution:
A kind of SCM Based Overspeed Alarm System, comprise car speed sensor, A D conv, microcontroller chip, LCDs and buzzer phone; Described car speed sensor by A the D conv with the microcontroller chip, be connected, be connected with LCDs and buzzer phone on the microcontroller chip.
Described car speed sensor adopts the 3C08 car speed sensor.
Described A the D conv adopt the TLC0838A/D conv.
Described microcontroller chip adopts the AT86C51 micro controller system.
Described LCDs adopts the TM035KDH04 LCDs.
Described buzzer phone adopts the KS-1407T2P40A buzzer phone.
The utlity model has following advantage:
First: when overspeed driving car, give the alarm, can remind the chaufeur Reduced Speed Now.
Second: for the chaufeur of not listening alarm, can record the record of bad behavior of driving over the speed limit, facilitate the traffic police to manage.
The 3rd: prevent that chaufeur from normally travelling in the overspeed detection district, and the bad phenomenon of driving over the speed limit outside the overspeed detection district.
The accompanying drawing explanation:
The structural representation that Fig. 1 is an example of the present utility model;
Fig. 2 is workflow schematic diagram of the present utility model;
Wherein: 1 is car speed sensor; 2 be A the D signal converter; 3 is the microcontroller chip; 4 is buzzer phone; 5 is LCDs.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Referring to Fig. 1, the utility model is a kind of Overspeed Alarm System of basic micro controller system, comprise car speed sensor, A D conv, microcontroller chip, LCDs and buzzer phone; Described car speed sensor by A the D conv with the microcontroller chip, be connected, be connected with LCDs and buzzer phone on the microcontroller chip.
In the process of moving, car speed sensor 1 is passed to microcontroller chip 3 by the current vehicle speed signal to automobile, and microcontroller chip 3 compares current vehicle speed with limiting maximum speed, if current vehicle speed is less than restriction maximum speed, traffic safety.If current vehicle speed is greater than the restriction maximum speed, the microcontroller chip will send instruction to buzzer phone 4 and LCDs 5, buzzer phone 4 can give the alarm, LCDs 5 can show the printed words of " vehicle that you drive is with hypervelocity; please slow down and go slowly ", if the hypervelocity time surpasses one minute, buzzer phone 4 can continue to report to the police, LCDs 5 records current vehicle speed, current time and hypervelocity time length.
Referring to Fig. 2, workflow of the present utility model is as follows:
Step 1: initialization.
Step 2: microcontroller chip 3 gathers the signal of car speed sensor 1.
Step 3: microcontroller chip 3 compares the vehicle speed signal collected with limiting maximum speed, if current vehicle speed is greater than the restriction maximum speed, proceed to step 4, otherwise return to initialization.
Step 4: microcontroller chip 3 is controlled buzzer phones 4 warnings of sounding, and LCDs 5 shows " vehicle that you drive, to exceed the speed limit, please slow down and go slowly ".
Step 5: microcontroller chip 3 judges that the hypervelocity time, whether over one minute, is to proceed to step 6, otherwise enters initialization.
Step 6: microcontroller chip 3 is controlled buzzer phone 4 and is continued to report to the police, and LCDs records current vehicle speed, current time and hypervelocity time length.
Advantage of the present utility model is mainly reflected in: when the overspeed of vehicle that travels on express highway, can remind timely chaufeur, allowing chaufeur slow down goes slowly, reduce the traffic accident of running at high speed and causing, also can record the hypervelocity information of vehicle simultaneously, facilitate the inspection of traffic police to overspeed of vehicle, to the traffic police, provide favourable evidence, thereby supervise chaufeur not drive over the speed limit.Therefore, developing a set of Overspeed Alarm System tool is of great significance.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, although the present invention discloses as above with preferred embodiment, yet not in order to limit the present invention, any those skilled in the art, within not breaking away from the technical solution of the present invention scope, when the method that can utilize above-mentioned announcement and technology contents are made a little change or be modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solution of the present invention, any simple modification of above embodiment being done according to technical spirit of the present invention, equivalent variations and modification, still belong in the scope of technical solution of the present invention.
