Abstract
The utility model discloses an alarm device for limiting speed of an automobile. The alarm device consists of a digital speedometer, a speed setting circuit, a speed detecting circuit and an alarm speed-limiting circuit, wherein the speed setting circuit is connected with the digital speedometer; the speed detecting circuit and the digital speedometer carry out data communication; the execution commands are transmitted by the alarm speed-limiting circuit; in the utility model, the detected vehicular speed value is compared with the preset value of the speed setting circuit by the speed detecting circuit; if the vehicular speed exceeds the prearranged speed, the alarm is given and the vehicular speed is controlled within the preset speed, thus ensuring the driving safety; and the alarm device has the benefits of simple structure, good concept, good alarm effect, long service life and the like.
Description
Technical field
The utility model relates to a kind of warning device, especially relates to a kind of automobile speed limit warning device.
Background technology
In the actual life, automobile has become the important vehicles of people's trip, running car has different vehicle-speed limit in different highway sections, but be difficult to control in the process of moving, do not note to cause the loss on personnel and the property slightly, and the warning reminding of existing overspeed alarm when just the driver being driven over the speed limit, the speed limit alarm device that does not also have pair speed of a motor vehicle to control at present.
The utility model content
The utility model provides a kind of automobile speed limit warning device at the prior art deficiency.
For realizing the above object, the technical solution adopted in the utility model is:
A kind of automobile speed limit warning device is become by digital speedometter, speed of a motor vehicle initialization circuit, speed of a motor vehicle testing circuit and warning speed limit circuit bank; Wherein speed of a motor vehicle initialization circuit is connected with digital speedometter, and speed of a motor vehicle testing circuit and digital speedometter carry out data communication, and fill order is passed on by warning speed limit circuit.
The utility model is compared detected speed of a motor vehicle numerical value by speed of a motor vehicle testing circuit with speed of a motor vehicle initialization circuit default value, exceed then and to report to the police and the speed of a motor vehicle is controlled in the preset vehicle speed, guaranteed traffic safety, integral body has simple in structure, be skillfully constructed, it is effective to report to the police, beneficial features such as long service life.
Description of drawings
Fig. 1 is the utility model frame principle figure;
Fig. 2 is the utility model circuit principle structure figure;
Embodiment:
As Fig. 1, shown in 2, a kind of automobile speed limit warning device is made up of digital speedometter 1, speed of a motor vehicle initialization circuit 2, speed of a motor vehicle testing circuit 3 and warning speed limit circuit 4; Wherein speed of a motor vehicle initialization circuit is connected with digital speedometter, and speed of a motor vehicle testing circuit and digital speedometter carry out data communication, and fill order is passed on by warning speed limit circuit.During concrete enforcement, three code switchs and the digital speedometter of speed of a motor vehicle initialization circuit join, wherein S1 is used to preset hundred figure places, S2 is used to preset tens, S3 is used to preset units, when having only digital identical that the numeral that shows when digital speedometter and code switch preset like this, S1, S2, S3 is the while output low level, through the rejection gate output high level of 4023 chips, diode VT1, the VT2 saturation conduction, the relay K action, the closed short circuit of its normally opened contact the accelerating system of automobile, alarming horn sends chimes of doom simultaneously, reminds the driver to note, when car deceleration is in setting is tested the speed, automobile normal running; If not hypervelocity or Reduced Speed Now, this device is failure to actuate, and automobile is cruising still.
The utility model utilizes the speed of a motor vehicle testing circuit Real-Time Monitoring speed of a motor vehicle, finds to exceed that setting value is reported to the police immediately and restricted speed, has guaranteed traffic safety, and integral body has simple in structure, is skillfully constructed, and it is effective to report to the police, the beneficial features such as long service life.
