[0023] Specifically, refer to Figure 1 、 Figure 3 and Figure 4 As shown, the infrared transmitting module 30 is respectively connected to the main control module 10 and the display light board 20 under test, so that the infrared transmitting module 30 receives the control command of the main control module 10 to start the display light board 20 under test. To be precise, the infrared transmitting module 30 is connected to the main control module 10 through the START_TX port and the START_RX port, and the infrared transmitting module 30 is infraredly connected to the display light board 20 under test. The main control module 10 built into the detection device transmits a remote control command to the display light board 20 under test through the infrared transmitting module 30. The light board receives the remote control signal and starts to enter the test operation. No external remote control is required, making the test more efficient and cost-saving. It should be understood that the display light board 20 under test is connected to the main control module 10 through the DP_CLK_x port and the DP_DAT_x port, so that the main control module 10 sends commands to the display light board during the test and lights up the LED lights on the display light board 20 under test in sequence.

[0024] Specifically, refer to Figure 1 and Figure 5 As shown, the current acquisition module 40 is a communication level conversion circuit composed of resistors R3\R4\R5\R7 and transistors Q1\Q2, which is connected to the display light board 20 under test through the +I_x port and the -I_x port, so that the current acquisition module 40 reads the current value of the display light board 20 under test. The current acquisition module 40 is connected to the main control module 10 through the CUR_RX_x port and the CUR_TX_x port, so that the current acquisition module 40 reads the current of the display light board 20 under test and transmits the current value information to the main control module 10;

[0025] Specifically, refer to Figure 1 and Figure 6 As shown, the display module 50 is connected to the main control module 10, so that the main control module 10 receives the current value information read by the current acquisition module 40 and transmits the signal to the display module 50. To be precise, the display module 50 is an LED liquid crystal display screen. The main control module 10 is connected to the display module 50 through the LCD_TX port and the LCD_RX port.

After the main control module 10 processes the information of the current acquisition module 40, when a detection fault occurs, the main control module 10 sends a command to the buzzer driving module 60, and the buzzer unit BZ issues a fault alarm prompt.

[0027] In addition, it also includes a power module, which includes a main control power unit and a light board power unit.
