Along with the fast development of Domestic Automotive Industry, the increasing sharply of automobile pollution, motor traffic accidents also increases thereupon.In the vehicle traveling process; Some large-scale transportation lorries particularly; Regular meeting causes exactly braking deceleration information, direction information to be passed to back vehicle because of Brake lamp fault, steering indicating light fault driver can't discover, thereby causes pernicious traffic hazard; Especially when night running, the risk that accident occurs is higher.
For improving the security of vehicle '; Many automakers have installed the braking pilot lamp at panel board; But this pilot lamp can only show the good of braking light switch, can not the objective working condition that reflects Brake lamp all sidedly, damage or line end fault such as open circuit all can cause one or two Brake lamp not work like Brake lamp bad earth, bulb; And in these cases, the braking pilot lamp of panel board is but glittering as usual.
Dispose flasher in the steering, when the steering indicating light of vehicle had fault, the glittering frequency of flasher can change; But concerning some large cars; Because steering indicating light is many, the change of frequency of flasher is not obvious, and the driver of general long-distance driving is difficult to judge steering indicating light fault has taken place.
Summary of the invention
Technical matters to be solved by this invention is to overcome system complex that prior art exists, adopt problem such as sensor cost height, provide a kind of and had easy and simple to handle, dependable performance, highly versatile, be easy to install, in the satisfied automobile enterprise of low cost of manufacture, automotive transportation enterprise commerial vehicle driving process to the commerial vehicle shunt formula braking in a turn lamp condition monitoring system of safety requirements.
Consult Fig. 1, for solving the problems of the technologies described above, the present invention adopts following technical scheme to be achieved.Commerial vehicle shunt formula braking in a turn lamp condition monitoring system provided by the present invention is made up of shunt test section A and light source detection part B.
Shunt test section A is made up of shunt 1.
Light source detection part B is made up of photoresistance 3 and divider resistance 4.
An end of photoresistance 3 is connected with the negative electrical wire of 5V power supply among the light source detection part B; The other end of photoresistance 3 is connected with an end electric wire of divider resistance 4; The other end of divider resistance 4 is connected with 5V positive source electric wire, and the common terminal of photoresistance 3 and divider resistance 4 is connected with the output terminal U02 electric wire of light intensity signal.
The resistance value of the shunt 1 described in the technical scheme should be 0.25～0.5 times of lamp 2 resistance value to be detected.
The resistance value of the photoresistance 3 illumination states described in the technical scheme should be 0.1～0.5 times of resistance value of divider resistance 4.
The invention has the beneficial effects as follows:
(1) condition monitoring system of motor turning Brake lamp of the present invention adopts the detecting element of shunt as braking in a turn lamp power supply break-make; This element price is lower; Easy for installation; Through this signal of sensor, can directly judge has no current to pass through the braking in a turn lamp, thereby judges accurately whether braking in a turn lamp two ends have.
(2) condition monitoring system of motor turning Brake lamp of the present invention has the function of the state of real-time monitoring motor turning Brake lamp; Owing to adopt photoresistance; Whether glittering, realize the malfunction of accurate fast monitored motor turning Brake lamp if directly detecting the motor turning Brake lamp, use the photoresistance cost low; Working stability, efficient is high.Avoided of the traffic hazard of braking in a turn lamp because of can't promptly and accurately reporting to the police and take place.

Among the figure: A. shunt test section, B. light source detection part, 1. shunt, lamp 2. to be detected, 3. photoresistance, 4. divider resistance.
Embodiment
Below in conjunction with accompanying drawing the present invention is made further detailed description:
The condition monitoring system of motor turning Brake lamp of the present invention has the function of real-time monitoring motor turning Brake lamp duty; Through shunt monitoring motor turning Brake lamp two ends whether electricity is arranged, and whether glittering through photoresistance monitoring motor turning Brake lamp.The invention provides a kind of stable performance, simple in structure, highly versatile, be easy to install, low cost of manufacture, commerial vehicle shunt formula braking in a turn lamp condition monitoring system easy to install and use.
Consult Fig. 1, commerial vehicle shunt formula braking in a turn lamp condition monitoring system is made up of shunt test section A and light source detection part B.
Shunt test section A is made up of shunt 1.
Light source detection part B is made up of photoresistance 3 and divider resistance 4.
An end of photoresistance 3 is connected with the negative electrical wire of 5V power supply among the light source detection part B; The other end of photoresistance 3 is connected with an end electric wire of divider resistance 4; The other end of divider resistance 4 is connected with 5V positive source electric wire, and the common terminal of photoresistance 3 and divider resistance 4 is connected with the output terminal U02 electric wire of light intensity signal.
The resistance value of shunt 1 should be 0.25～0.5 times of lamp 2 resistance value to be detected, and the resistance value of photoresistance 3 illumination states should be 0.1～0.5 times of resistance value of divider resistance 4.
