[0002] Traffic lights are lights that direct traffic, usually consisting of red, green, and yellow lights. A red light means no passage, a green light means passage is allowed, and a yellow light means a warning.

[0003] Traffic signal fault detection devices are devices or systems designed to monitor and detect whether traffic lights on roads are functioning properly. These devices are designed to ensure the effectiveness and safety of traffic lights in traffic management; common fault detection methods, such as voltage monitoring, monitor whether the supply voltage is within the normal range. Usually, voltage monitoring devices can be installed directly inside the electrical box of the signal light, so that the voltage can be measured in the signal light control circuit.

[0004] However, the installation parts of the existing voltage monitoring devices are all integrally formed, and the position of the installation holes of the voltage monitoring devices cannot be adjusted. In addition, due to the small space in the street light electrical box, when drilling holes, it is necessary to measure the length and height between the installation holes on the voltage monitoring device before drilling holes, which is a cumbersome process. As a result, the voltage monitoring device is difficult to install, which is not conducive to the promotion and use of the device. Utility Model Content

[0025] like Figures 1 to 5 As shown, the traffic signal fault detection device of the exemplary embodiment includes a voltage monitoring device 1, the voltage monitoring device 1 is a device for monitoring the voltage state of a circuit or a device, and also includes a fixing structure 2, two connecting plates 3 are installed on the voltage monitoring device 1, a strip hole 4 is provided on the connecting plate 3, two first slide grooves 5 are provided in the strip hole 4, first card slots 6 are equidistantly arranged in the first slide groove 5, a first slider 7 is slidably installed in the first slide groove 5, a mounting seat 8 is installed on one side adjacent to the two first sliders 7, and the mounting seat 8 is located in the strip hole 4, a mounting hole 9 is provided on the mounting seat 8, a connecting shell 10 is installed at the bottom end of the mounting seat 8, a partition 11 is provided in the connecting shell 10, and the partition 11 divides the connecting shell 10 into a first cavity 14 and a second cavity 15;

[0026] It also includes a fixing structure 2, which includes a limiting hole 201, a handle 202, a block 203, a cylinder 204, a column 205 and a first spring 206. The limiting hole 201 is set on the connecting shell 10, the handle 202 is slidably connected to the limiting hole 201, and both ends of the handle 202 extend out of the limiting hole 201. A block 203 is installed at the end of the handle 202 away from the limiting hole 201, and the block 203 extends out of the first cavity 14 and is inserted into the first slot 6. The cylinder 204 is set in the first cavity 14, and the cylinder 204 is connected to the partition 11. The cylinder 205 is located in the cylinder 204, and one end of the cylinder 205 extends out of the cylinder 204 and is connected to the block 203. The first spring 206 is set between the cylinder 204 and the cylinder 205, and provides an elastic force for the cylinder 205 to move away from the cylinder 204.

[0027] The mounting seat 8 is arranged in the strip hole 4; the mounting seat 8 can be moved up and down in the strip hole 4 through the first slider 7 and the first slide groove 5, so that the position of the mounting seat 8 can be changed; by changing the position of the mounting seat 8, the position of the mounting hole 9 on the voltage monitoring device 1 can be changed, so that the voltage monitoring device 1 can be installed in different types of street lamp boxes; by adjusting the position of the mounting hole 9, the assembly process is easier and the parts are ensured to be correctly aligned and connected. This helps to improve the accuracy and efficiency of assembly.

[0028] During the specific operation, when the handle 202 is moved outward, the handle 202 can push the cylinder 205 back into the cylinder 204, and compress the first spring 206, so that the block 203 moves out of the inner cavity of the first slot 6, thereby releasing the fixation of the mounting seat 8. By moving the mounting seat 8 upward or downward, the position of the mounting hole 9 can be adjusted. When it moves to the desired position, the handle 202 is released, and the first spring 206 pops out, which can push the block 203 to re-enter the first slot 6 at other positions, so that the mounting seat 8 can be fixed to ensure that the mounting seat 8 does not slide during installation. After the mounting seat 8 is fixed, the screw passes through the mounting hole 9 to install the voltage monitoring device 1 in the street light box. At the same time, when punching holes in the street light box, it is only necessary to ensure that the distance between the holes is the same as the length of the mounting hole 9 on the voltage monitoring device 1, and the upper and lower positions can be conveniently adjusted according to the actual installation.

[0029] The voltage monitoring device 1 is an existing mature technology. The voltage monitoring device 1 is a device for monitoring the voltage status of a circuit or device.

At the same time, the signal conditioning module 103 processes the signal output by the voltage sensor 102 to improve the quality and accuracy of the signal. The processor 104 receives the processed signal and performs corresponding functions, such as data recording, display or alarm. And the communication interface conveys the measured voltage information to the user or other devices.
