Abstract
The utility model discloses a light monitoring and alarming device for automotive vehicles, which is provided with a testing circuit in a shell. The testing circuit is composed of a sample circuit, a control circuit and an alarm circuit. When the malfunction of a braking indication lamp happens, the sample is taken via shunting resistance Ro in the sample circuit, and the signal of the voltage variation is input to the control circuit to make the control circuit lie in the operating state, that is, a transistor BG1 is conducted, and a collector electrode outputs a high level to trigger the alarm circuit to dispatch the alarm signal. The light monitoring and alarming device for automotive vehicles has the advantages of simple circuit, high reliability, convenient installation, convenient operation, and low cost.
Description
The utility model is a kind of light monitor and alarm unit that is used on the power actuated vehicle.
At present, the design plan and the patented technology that are used for the light monitor and alarm unit on the automobile have a lot, but because these technical schemes are the general designs of all light on the monitoring machine motor vehicle is departure point, promptly by all light on the total supervisory gear machines motor vehicle, make a detecting device that tens even more detection tabs will be arranged, give and install, use and bring very big difficulty, therefore be difficult to implement.
The purpose of this utility model is to realize a kind of automobile brake light fault alarm, and the brake lamp of automobile is detected, and when lamp damages, can report to the police.This device detection tabs is few, is convenient to install implement.Have simple in structurely, good reliability, report to the police accurately advantages such as low price.
Main points of the present utility model are: testing circuit is housed in housing, and testing circuit is by sampling circuit, and control circuit and warning circuit are formed.When braking indicator lamp et out of order, by the signal input control circuit of sampling circuit, make control circuit in running order with change of voltage, trigger warning circuit and send alerting signal.
Be elaborated below by accompanying drawing.
Accompanying drawing 1 is automobile brake light fault alarm testing circuit figure.
Accompanying drawing 2 is language type automobile brake light fault alarm testing circuit figure.
This device is that testing circuit is housed in housing, and as shown in Figure 1, testing circuit is made up of sampling circuit 1, control circuit 2 and warning circuit 3, and sampling circuit is to be made of the shunt resistance R0 that joins with two test side B, L; The bias circuit that control circuit includes transistor BG1 and joins with test side B, ground terminal E, this bias circuit is made up of diode D1 and the resistance R 2 back institutes of connecting with diode D2, resistance R 3 in parallel, the emitter of above-mentioned transistor BG1 and test side B join, its collecting electrode joins with ground terminal E by resistance R 1, and its base stage is connected between the diode D1 and resistance R 3 in the above-mentioned bias circuit; The input end of warning circuit and test side B join, and mouth and ground terminal E join, and the collecting electrode that triggers input end and aforementioned transistor BG1 joins.During installation, as shown in Figure 1, test side B, L are connected in the brake lamp optical link 4, ground terminal E bonding gets final product.Shunt resistance R0 in the sampling circuit when electric current flows through, produces sampling voltage Vs with after the brake lamp optical link is connected.Transistor BG1 in the control circuit selects the sharp cut-off aerotron for use, bias voltage Vb is selected by diode D1, D2 resistance R 2, R3, and the mode of operation of control circuit determined by Vb-Vs, under the normal condition, Vb-Vs＜06V, transistor BG1 ends, the collecting electrode output low level; When braking indicator lamp et out of order, Vb-Vs＞06V, transistor BG1 conducting, collecting electrode output high level triggers warning circuit and sends alerting signal.
Warning circuit adopts known technology, can be audible alarm circuit, or the language alarm circuit, also can be the light warning circuit.
As shown in Figure 1, the audible alarm circuit that warning circuit 3 is made up of buzzing sheet YD, voltage transformer T, oscillistor BG2, capacitor C, diode D4, and it triggers the collecting electrode of input end by diode D3 and aforementioned transistor BG1 and joins.
As shown in Figure 2, warning circuit is the language alarm circuit.Adopted the language alarm circuit of applicant in the patent of 92243101 " reversing automobile siren hornes " by name, its warning circuit is by the language integrated package, audio amplifier circuit, power amplifier, the language alarm circuit that loudspeaker are formed.
In order to adapt to the power line voltage of different automobile types, the resistance value that only needs to change R0, R1, R3 gets final product.
The utility model major advantage is that circuit is simple, reliability is strong, is convenient to install implement, and is easy to use, low cost.
