Description
Technical field
The utility model relates to a kind of LED control system.
Background technology
LED light source the life-span, energy-conservation etc. in be all better than conventional lights, the structure of LED light source is more complicated than conventional lights simultaneously, and price is higher, have failed and will keep in repair instead of directly discard.Current LED control system does not have fault detection capability, and getting rid of to breakdown maintenance makes troubles.
Summary of the invention
For above-mentioned the deficiencies in the prior art part, the utility model provides a kind of LED control system with failure diagnosis.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of LED control system described in the utility model, it is characterized in that: the warning indicating module, key circuit module, power circuit block, the multiple LED drive module that comprise STC89C52 chip and be connected with STC89C52 chip, described warning indicating module comprises buzz circuit, multiple system mode indicating circuit and multiple LED and drives indicating circuit, described power circuit block is also powered for warning indicating module and multiple LED drive module, and described system mode indicating circuit, LED drive indicating circuit identical with the quantity of LED drive module.
Compared with prior art, the beneficial effects of the utility model:
A kind of LED control system described in the utility model, utilize the pwm pulse signal driving LED interrupting producing, carry out brightness regulation by the timing setting of STC89C52 chip internal and mode selection button, detect by the indicator light of correspondence the fault judging LED group, be beneficial to maintenance.
Accompanying drawing explanation
Fig. 1 is the system block diagram of a kind of LED control system described in the utility model.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of LED control system described in the utility model, it is characterized in that: the warning indicating module, key circuit module, power circuit block, the multiple LED drive module that comprise STC89C52 chip and be connected with STC89C52 chip, described warning indicating module comprises buzz circuit, multiple system mode indicating circuit and multiple LED and drives indicating circuit, described power circuit block is also powered for warning indicating module and multiple LED drive module, and described system mode indicating circuit, LED drive indicating circuit identical with the quantity of LED drive module.
In the present embodiment, system mode indicating circuit, LED drive the quantity of indicating circuit and LED drive module to be 2, and system mode indicating circuit, LED drive indicating circuit to be respectively used to detect the state of corresponding LED drive module.When the bright and buzzer of system state indicator sends warning, LED drives indicator light to go out, LED breaks down in loop.Now, if the reference voltage of drive circuit is 0, illustrate that LED is opened a way; If the reference voltage of drive circuit is normal, LED short circuit is described.Meanwhile, can be judged by corresponding indicator light that group LED breaks down, reach the object of fault detect.This system utilizes the pwm pulse signal driving LED interrupting producing, and carries out brightness regulation by the timing setting of STC89C52 chip internal and mode selection button, detects the fault judging LED group, be beneficial to maintenance by the indicator light of correspondence.
