The utility model content

Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and the LED power supply smart detection system that a kind of detection method is simple, detection efficiency is high and lifting detects quality greatly is provided.

The technical scheme that the utility model adopts is: the utility model comprises that host computer, slave computer detect control module and measured device access unit, described slave computer detects control module and is used for by described measured device access unit the tested LED power module of periphery being detected and analyzes and judge, described host computer is used for the described slave computer of control and detects control module to the testing process of described tested LED power module, and real time record detects data.

Preferably, described slave computer detects control module and is connected with power circuit, extra load output circuit, pilot lamp display circuit and buzzer alarm circuit, described measured device access unit comprises the measured signal place in circuit, and described tested LED power module is connected to described slave computer by described measured signal place in circuit and detects control module.

Preferably, described tested LED power module comprises rectification circuit, auxiliary power circuit, pfc circuit, pwm circuit, DC output circuit and the constant-current circuit that all is electrically connected with described measured signal place in circuit.

The beneficial effects of the utility model are: detect control module and measured device access unit because the utility model comprises host computer, slave computer, described slave computer detects control module and is used for by described measured device access unit the tested LED power module of periphery being detected and analyzes and judge, described host computer is used for the described slave computer of control and detects control module to the testing process of described tested LED power module, and real time record detects data; Adopt the utility model detection system that the LED power module is detected, can reduce the time of production line check LED power module greatly, enhance productivity, simultaneously to artificial non-detectable circuit, this LED power module test fixture not only can be realized, can also detect exactly soon simultaneously, failure condition for out of order power module can at length be stored on computers, these functions have been arranged, not only make things convenient for the production line check, the rate of enhancing productivity and be up to the standards, and be convenient to the data analysis statistics of malfunctioning module and the statistics of product percent of pass, also be convenient to the cause investigation of out of order power module simultaneously.

Embodiment

As shown in Figure 1 and Figure 2, the utility model relates to a kind of LED power supply smart detection system, is used for LED power module and driver module thereof and tests and diagnose.This system comprises that host computer 1, slave computer detect control module 2 and measured device access unit 3, described slave computer detects control module 2 and is used for detecting by the tested LED power module of 3 pairs of peripheries of described measured device access unit, described host computer 1 is used for the testing process that the described slave computer of control detects 2 pairs of described tested LED power modules of control module, and real time record detects data.

Described slave computer detects control module 2 and is connected with power circuit 4, extra load output circuit 5, pilot lamp display circuit 6 and buzzer alarm circuit 7, described measured device access unit 3 comprises measured signal place in circuit 8, and described tested LED power module is connected to described slave computer by described measured signal place in circuit 8 and detects control module 2.Described extra load output circuit 5 adopts LED load pilot relay, and each functional module of described pilot lamp display circuit 6, described buzzer alarm circuit 7 corresponding described tested LED power modules is provided with pilot lamp and hummer one to one.Described tested LED power module comprises the functional circuit module such as rectification circuit 10, auxiliary power circuit 11, pfc circuit 12, pwm circuit 13, DC output circuit 14 and constant-current circuit 15 that all are electrically connected with described measured signal place in circuit 8.

Detection method of the present utility model is according to substep the each several part functional module of power module and driver module thereof to be carried out automatic diagnosis to detect, and concrete implementation is as follows:

After described slave computer detects control module 2 and receives start detection order from described host computer 1 or field personnel, detect and diagnose progressively starting each tested module to the LED power supply, concrete steps are:

The first step: detect control module 2 by described slave computer and control tested LED power module AC operating voltage, make it to export 220V (AC), detect the output voltage of tested driver module rectifier bridge whether in the scope the inside that requires, thereby whether described rectification circuit 10 damaged judge; Delay time simultaneously and open LED load pilot relay behind the 10ms, output LED load allows tested LED power module work under nominal load;

Second step: after the first step, behind the time-delay 500ms, described slave computer detects control module 2 and detects pfc circuit and the pwm circuit VCC voltage of IC separately in real time, according to real-time detected VCC1 (PFC) and VCC2 (PWM), judge whether within the scope that designing requirement allows thereby whether the auxiliary power circuit 11 of PFC and PWM damaged judge;

The 3rd step: after the detection of second step is finished, described slave computer detects the output voltage V H that control module 2 detects pfc circuit in real time, according to detected VH value, judge whether within the scope that designing requirement allows thereby whether described pfc circuit 12 damaged judge;
