This repair method is cumbersome, requiring the removal of numerous screws from the control box to access the internal output interfaces. This is not only inefficient but also carries the risk of damaging the interfaces due to improper operation. Furthermore, because the signal voltage of LED displays changes dynamically, traditional tools struggle to accurately determine signal abnormalities, leading to inaccurate fault location and time-consuming troubleshooting. An integrated, specialized, rapid on-site repair tool addresses these pain points. Utility Model Content

The first connection terminal 4 is used to connect to the control box 6 of the light strip display screen to detect power supply and control signals. The second connection terminal 5 is used to connect to the output wires 7 of the light strip display screen to detect the control signals of each output wire.
[0036] For example, the circuit board is housed inside the housing 1. One surface of the housing 1 is provided with a status display panel 2, and the other surface is provided with a voltage display screen 3. A first connection terminal 4 and a second connection terminal 5 are respectively located at both ends of the housing 1 and are electrically connected to the circuit board. The control box 6 of the light strip display can be connected through the first connection terminal 4, and the power supply signal is displayed through the voltage display screen 3, while the control signal is displayed through the status display panel 2. The second connection terminal 5 can be connected to the output wires 7 of the light strip display, and the control signal of each output wire 7 is displayed through the status display panel 2.
[0037] As can be seen from the above technical solution, the integrated circuit board of the box 1, the status display panel 2, the voltage display screen 3, and the first and second connection terminals 5 form an integrated portable maintenance tool that can be directly connected to the control box 6 or the output cable, thereby quickly detecting power supply and control signals, and intuitively feeding back the status through the display panel, simplifying the on-site maintenance process and improving the accuracy of fault location and operational efficiency.
[0038] The circuit board includes a power supply detection module 8 and a signal detection module 9. The input terminal of the power supply detection module 8 is connected to the first connection terminal 4, and the output terminal is connected to the voltage display screen 3 and the signal detection module 9. The power supply detection module 8 receives the voltage from the control box 6 and displays it on the voltage display screen 3. The circuit board incorporates the power supply detection module 8 and the signal detection module 9. The power supply detection module 8 specifically processes voltage information and outputs it to the voltage display screen 3 and the signal detection module 9. This modular structure allows power supply and signal detection to work together, ensuring accurate monitoring of the power supply status and improving the comprehensiveness and reliability of the detection.
[0039] Please refer to Figure 6 The power supply detection module 8 includes a step-down circuit. An existing step-down circuit can be used. This structure can reduce the high input voltage to a preset voltage and output power to various components within the device.
[0040] The input terminal of the signal detection module 9 is connected to the first connection terminal 4 and the second connection terminal 5, and the output terminal is connected to the status display panel 2.

The signal detection module 9 is connected to both the first connection terminal 4 and the second connection terminal 5 and directly drives the status display panel 2, allowing the acquisition of control signals from the control box 6 and the wiring, and displaying the results intuitively on the panel. This enables users to quickly distinguish abnormal signal sources, accurately locate fault points, and improve the targeting and efficiency of detection.
[0041] The signal detection module 9 includes multiple detection units, and the status display panel 2 includes multiple light groups. The detection units are connected to the light groups in a one-to-one correspondence. The signal detection module 9 adopts a structure in which multiple detection units correspond one-to-one with the multiple light groups on the status display panel 2. Each detection unit is responsible for one signal channel. The working status of the corresponding channel is directly reflected by the status change of the light group. This parallel detection structure enables multiple signal faults to be identified simultaneously, improving the accuracy of detection and parallel processing capability.
[0042] The second connection end 5 includes multiple connection terminals 51, each of which is connected to a detection unit. This structure allows for the simultaneous connection of multiple output cables 7, enabling synchronous detection of signals from multiple cables.

The M12 female connector structure of the connection terminal 51 ensures reliable connection with common LED strip wires, reduces the risk of poor contact or connection errors, and facilitates quick plugging and unplugging on site, improving the practicality and compatibility of the tool.
[0044] Please refer to Figures 7 to 9 The signal detection module 9 includes a signal transmission chip and multiple driver chips. The signal transmission chip receives control signals and outputs them to the driver chips, which then drive the LED groups for display according to the control signals. The signal transmission chip U1 can be an MC74HC245A. In this embodiment, each detection unit has three driver chips: driver chip U2, driver chip U3, and driver chip U4. The driver chips can be UCS9812. The signal detection module 9 includes a signal transmission chip and multiple driver chips. The signal transmission chip is responsible for receiving and distributing control signals, while the driver chips drive the corresponding LED groups for display, making the display status more reliable and intuitive.
[0045] In this embodiment, the first connection terminal 4 is an M16 female connector. The first connection terminal 4 adopts an M16 female connector structure, which can directly match the output interface of the control box 6, providing a stable and reliable electrical connection, simplifying the connection steps, and improving the convenience of on-site operation.
[0046] To facilitate understanding of the above-mentioned rapid repair device for light bar displays, its working principle is described below: I. Control Box 6 Testing Steps: First, connect the first connection terminal 4 to the output terminal of the control box 6 to ensure that the control box 6 is powered on. Observe whether the voltage displayed on the voltage display screen 3 is consistent with the voltage of the control box 6. If they are consistent, it means that the voltage of the control box 6 is normal. If the voltage is abnormal, it is determined that there is a fault in the continuity of the adapter board fuse and the power supply link of the control box 6.
[0047] If the voltage display is normal, use a control terminal such as a computer to open the test software and output control signals, such as controlling the light strip to play different colors. Observe whether the status display panel 2 displays normally. If the display is abnormal, the adapter board chip and signal connector may be faulty.
[0048] II. Seven testing steps for output cables: First, test control box 6 according to the steps described above to ensure it functions correctly. Connect the output cables 7 to the second connection terminals 5 one by one, ensuring control box 6 is powered on and connected to the network. Use a control terminal, such as a computer, to open the test software and output control signals, for example, to control the light strips to play different colors. Observe whether the status display panel 2 displays normally. If a certain light group displays abnormally, the branch of its corresponding output cable 7 is open-circuited. If all light groups on the status display panel 2 display abnormally, it is determined that the main line of output cable 7 is open-circuited and the cable needs to be replaced.
