Description
Technical field
The utility model relates to a kind of auto electronic warning device, is specifically related to a kind of Automobile Lamp Alarm Device.
Technical background
Automobile lamp occupies critical role in traffic safety, especially flasher and stop lamp are reminded the vehicle at automobile rear when direction indicator lamp is used for motor turning; And stop lamp is used to remind this car of front vehicle reducing the speed of a motor vehicle; Avoid the generation of rear-end collision, stop lamp and direction indicator lamp use more frequent, therefore also are easier to damage; And stop lamp and direction indicator lamp damage and are difficult for being discovered, and are easy to generate traffic accident.In time remind the driver extremely important when therefore, direction indicator lamp and stop lamp damage.
Summary of the invention
For fear of defective of the prior art and deficiency, the purpose of the utility model is, a kind of Automobile Lamp Alarm Device is provided, and this warning device cost is low, and volume is little, is prone to install.
In order to realize above-mentioned task, the utility model adopts following technical scheme to be achieved:
A kind of Automobile Lamp Alarm Device is characterized in that, comprising:
Two current sensors are used for gathering respectively the electric current of direction indicator lamp and brake light circuit;
One signal conversion module is used for converting the current signal of direction indicator lamp and stop lamp to voltage signal;
One single-chip microcomputer is used for the signal of processing signals modular converter, and judges;
One audible-visual annunciator is used to send sound and light alarm;
Two current sensors are connected with signal conversion module, and the output of signal conversion module is connected the input of single-chip microcomputer, and audible-visual annunciator is connected at the output of single-chip microcomputer.
Other characteristics of the utility model are:
Described single-chip microcomputer adopts the PIC12F675 single-chip microcomputer.
The Automobile Lamp Alarm Device of the utility model, signal conversion module changes into voltage signal with direction indicator lamp of gathering and the electric current in the brake light circuit, is input in the single-chip microcomputer; Voltage signal when single-chip microcomputer does not damage this signal and car light compares, if direction indicator lamp is not opened, then the signal conversion module output valve is zero; Do not report to the police, if during the threshold value that the signal conversion module output valve sets greater than single-chip microcomputer, then car light is intact; Do not report to the police; If during the threshold value that the signal conversion module output valve sets less than single-chip microcomputer and non-vanishing, then car light damages, and buzzer and diode in the single-chip microcomputer instruction audible-visual annunciator carry out sound and light alarm.This Automobile Lamp Alarm Device can remind driver's car light to damage easily, eliminates safe hidden trouble, and has improved driver and conductor's safety factor of travel.
Description of drawings
Fig. 1 is the theory diagram of the Automobile Lamp Alarm Device of the utility model.
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
Embodiment
With reference to Fig. 1, this instance provides a kind of theory diagram of Automobile Lamp Alarm Device, comprising:
Two current sensors 1 are used for gathering respectively the electric current of direction indicator lamp and brake light circuit;
One signal conversion module 2 is used for converting the current signal of direction indicator lamp and stop lamp to voltage signal;
One single-chip microcomputer 3 is used for the signal of processing signals modular converter, and judges;
One audible-visual annunciator 4 is used to send sound and light alarm;
In this instance; Current sensor is installed in respectively in the circuit of direction indicator lamp and stop lamp, and single-chip microcomputer adopts the PIC12F675 single-chip microcomputer, this chip volume is little, at a high speed, low-power consumption; Have stronger I/O driving force simultaneously, can directly drive Light-Emitting Diode and buzzer in the audible-visual annunciator 4.
Its operation principle is: two current sensors 1 are used for gathering respectively the electric current of direction indicator lamp and brake light circuit; Signal conversion module 2 is used for current signal with direction indicator lamp and stop lamp and converts voltage signal to and import into to single-chip microcomputer 3, single-chip microcomputer 3 with the signal of signal conversion module 2 outputs and the threshold range that sets relatively, when direction indicator lamp and stop lamp are not opened; Signal conversion module 2 is output as zero; This moment, the sound and light alarm module 4 was not reported to the police, and when signal conversion module 2 output valves during greater than the threshold value that sets, car light is in proper working order; Do not carry out sound and light alarm; When signal conversion module 2 output valves during less than the threshold value that sets and when non-vanishing, then car light damages, buzzer and diode in the single-chip microcomputer 3 instruction audible-visual annunciators 4 send sound and light alarm.This Automobile Lamp Alarm Device can effectively be monitored the car light working condition, improves driver and conductor's safety factor of travel, traffic safety hidden danger when reducing driving.
Although more than combine accompanying drawing that the technical scheme of the utility model is described, the utility model is not limited to above-mentioned specific embodiments and applications field, and above-mentioned specific embodiments only is schematic, guiding, rather than restrictive.Those of ordinary skill in the art under the situation that does not break away from the scope that the utility model claim protected, makes nonessential interpolation and replacement to the technical scheme of the utility model under the instruction of this specification, all belong to the protection range of the utility model.
