Abstract
The invention discloses a vehicle speed measurement and speed-limiting alarm device. The device comprises a magnetoelectric sensor for measuring the speed of a vehicle, a single-chip microcomputer, a vehicle speed setting module and an alarm unit, wherein the magnetoelectric sensor and the vehicle speed setting module are respectively connected with the signal input end of the single-chip microcomputer, and the signal output end of the single-chip microcomputer is connected with the alarm unit. According to the vehicle speed measurement and speed-limiting alarm device disclosed by the invention, a wheel rotational speed signal is detected through the magnetoelectric sensor and input into the single-chip microcomputer, the single-chip microcomputer is used for performing processing on the signal, calculating the speed of the vehicle and then displaying the speed of the vehicle on a display device, the corresponding speed of the vehicle can be selected through the vehicle speed setting module in different regions, and when the actual speed of the vehicle exceeds a set value, the voice alarm is performed so that the safety in driving can be increased.
Description
Technical field
The present invention relates to a kind of warning device, relate in particular to a kind of vehicle speed measurement and speed limit alarm device.
Background technology
Along with the quickening of modern life rhythm, People more and more is paid attention to concept of time, and electric motor car, private car are more and more, and driver's furious driving on the highway has become " arch-criminal " of road traffic accident, is " first killer " of highway road traffic safety.
It is multiple to cause the reason of furious driving to have, and has deliberately for it, has to drive energy in the way and do not concentrate and be not intended to cause for a long time; When the hypervelocity behavior takes place; Adopt warning device to send a kind of prompting, can make the driver who is not intended to for it realize the hypervelocity behavior at once, reduce the speed of a motor vehicle for the driver; For intentional driver for it, also play warning function to a certain degree simultaneously.
In some high-end automobiles, developed the alarm set of some speed limits and hypervelocity at present, but its complex structure belongs to the integrally-built part of vehicle, can not split out separately and use.So, press for a kind of easy, practical overspeed of vehicle alarm set in the market.
Summary of the invention
Technical matters to be solved by this invention is to the problem that relates in the background technology; Propose a kind of vehicle speed measurement and speed limit warning system, can show the real-time speed of a motor vehicle, and when the speed of a motor vehicle surpasses setting value with voice warning reminding driver; So that in time slow down, guarantee the safety of life and property.
The present invention adopts following technical scheme for solving the problems of the technologies described above:
A kind of vehicle speed measurement and speed limit alarm device; This device is made up of the magnetoelectric transducer that is used to measure the speed of a motor vehicle, single-chip microcomputer, speed of a motor vehicle setting module, alarm unit; Said magnetoelectric transducer, speed of a motor vehicle setting module are connected with the signal input part of single-chip microcomputer respectively, and the signal output part of single-chip microcomputer is connected with alarm unit.
As the further optimization of vehicle speed measurement of the present invention and speed limit alarm device, said magnetoelectric transducer is a Hall element.
As the further optimization of vehicle speed measurement of the present invention and speed limit alarm device, also comprise a LCDs, said LCDs is connected with said single-chip microcomputer.
As the further optimization of vehicle speed measurement of the present invention and speed limit alarm device, said alarm unit is that model is the speech chip of ISD2560.
As the further optimization of vehicle speed measurement of the present invention and speed limit alarm device, said speed of a motor vehicle setting module comprises at least one speed of a motor vehicle setting button.
The present invention adopts above technical scheme compared with prior art, has following technique effect:
The present invention utilizes magnetoelectric transducer to detect rotating speed; According to of the requirement of different running environments for the speed of a motor vehicle; Set the speed of a motor vehicle alarm threshold value in the key change single-chip microcomputer through the speed of a motor vehicle; When detecting actual vehicle speed above behind the setting threshold, carry out audio alert by the Single-chip Controlling alarm unit, increase travel safety.
Description of drawings
Fig. 1 is a warning device structural representation of the present invention.
Fig. 2 is the structural representation of a kind of embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing technical scheme of the present invention is done further detailed description:
Shown in Fig. 1, the present invention is a kind of vehicle speed measurement and speed limit alarm device, and this device is made up of magnetoelectric transducer, single-chip microcomputer, speed of a motor vehicle setting module, alarm unit, LCD.
Wherein, magnetoelectric transducer is fixed on magnet steel wheel place, is used to measure the rotating speed of wheel, then with its input single-chip microcomputer.Store the speed of a motor vehicle in the single-chip microcomputer in advance and limit threshold value; The pulse that the single chip computer measurement magnetoelectric transducer produces is to draw the rotating speed of wheel; Then its speed of a motor vehicle threshold value with storage is in advance compared; When actual vehicle speed surpasses setting speed of a motor vehicle threshold value, send control signal by single-chip microcomputer to alarm unit, the control alarm unit is reported to the police.
LCD is used to show speed information.Speed of a motor vehicle setting module is used for setting the speed of a motor vehicle threshold information that single-chip microcomputer is stored, and it is actual to be the key groups module.
As shown in Figure 2; As one embodiment of the present of invention; Wheel, Hall element, speed of a motor vehicle setting button 1, speed of a motor vehicle setting button 2, speed of a motor vehicle setting button 3, single-chip microcomputer, speech chip ISD2560, LCD by the band magnet steel are formed, and on the wheel limit of non-magnetic material, paste a magnet steel, and Hall element is fixed near the felly; The moving circle of wheel revolution, Hall element is just exported a pulse; Just can draw the rotating speed of wheel through the frequency of single chip computer measurement generation pulse; Single-chip microcomputer shows the real-time speed of a motor vehicle after to signal Processing at LCD MODULE.
The speed of a motor vehicle is set button 1, the speed of a motor vehicle and is set when button 2, the speed of a motor vehicle are set the speed of a motor vehicle alarm threshold value that button 3 stores respectively in revising single-chip microcomputer and use; Wherein set button 1 and can increase speed of a motor vehicle threshold value through the speed of a motor vehicle; Set button 2 through the speed of a motor vehicle and can reduce speed of a motor vehicle threshold value; Set button 3 through the speed of a motor vehicle and can confirm the speed of a motor vehicle threshold value set, perhaps return.After rotating speed surpassed certain setting value, the speech chip ISD2560 that links to each other with single-chip microcomputer will send alarm voice, can record the recording to own effectively household in this speech chip in advance, reminded the driver to slow down, and guaranteed safety.
