[0023] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0024] Reference Figure 1-4 The utility model embodiment is a fee display, which includes a mounting plate 1, a body 2 fixedly connected to the top of the mounting plate 1 and a display screen 3 embedded in the front side of the body 2, and a cleaning component for cleaning the display screen 3 is provided on the front side of the body 2;

[0025] The cleaning assembly includes two frames 4 fixedly connected to the outer side of the machine body 2, two guide rods 5 fixedly connected to the inner side of the frames 4, two movable plates 6 slidably connected to the outer sides of the guide rods 5, a brush 7 fixedly connected between the two movable plates 6, a roller 9 rotatably connected to the inside of one of the frames 4 and close to the top, a rope 11 wound around the outer side of the roller 9, and a motor 10 fixedly connected to the outer side of the frame 4 and close to the roller 9, the central axis of the roller 9 passes through the frame 4 and is fixedly connected to the output shaft of the motor 10, and the movable end of the rope 11 is connected to the adjacent movable plate 6;

[0026] When the display screen 3 needs to be cleaned, the motor 10 drives the roller 9 to rotate, and the rotating roller 9 can lower the rope 11, so that the brush 7 can fall freely under the action of gravity, and the brush 7 can clean the display screen 3 when it contacts the surface of the display screen 3. When the brush 7 is at the bottom, the motor 10 drives the roller 9 to rotate in the opposite direction to reel in the rope 11, so that the brush 7 can move upward to repeatedly clean the surface of the display screen 3, thereby ensuring the cleanliness and transparency of the display screen 3, allowing the user to clearly see the content on the display screen 3, and improving the user's experience.

[0027] It also includes an MBI5034 driver chip, a control circuit, a displacement register and an SDO output pin. The MBI5034 driver chip is used to drive the LED display and implement a forced open circuit error detection function. The control circuit is used to manage the working mode and timing of the MBI5034 chip. The displacement register is used to store error configuration data output by the MBI5034 chip. The SDO output pin is used to output error status data of LED fault point detection from the displacement register.

[0028] The principle of forced open circuit error detection of MBI5034 is based on the comparison of the actual output end withstand voltage (V6s) and the target value (Vo.TH) of 0.35V to determine the LED load status of each output end. When the "forced error detection" command is issued, the output end of MBI5034 will be turned on with a very small current for error detection. After the open circuit error detection is completed, the driver will move the error configuration data to the "shift register". The error status data stored in the register will be output to each bit through the SDO pin after the new data is input. Through the chip function on the hardware and the software to achieve accurate positioning of the LED fault point, the display module where the fault point is located and the specific coordinate position on the module can be located, so that maintenance and use personnel can quickly locate the fault point, find the fault point and repair it.

[0029] An L-shaped storage chamber 12 is fixedly connected to the front side of the body 2 and located above the display screen 3. A sealing plate 8 is fixedly connected to the bottom of the brush 7. When the brush 7 is moved into the storage chamber 12, the sealing plate 8 fits against the bottom of the storage chamber 12. When the brush 7 is not in use, it can be moved into the storage chamber 12 for storage. The sealing plate 8 at the bottom of the brush 7 cooperates with the storage chamber 12 to form a closed space, which is beneficial to protecting the brush 7 and reducing the contamination of the brush 7 by external dust.

[0030] A shading plate 15 is fixedly connected to the front side of the body 2 and one side close to the top. The shading plate 15 is used to reduce the interference of external light on the display content of the display screen 3, ensuring that the user can clearly see the display content of the fee display under different lighting conditions.

[0031] A status indicator light 13 is embedded inside the front side of the mounting plate 1. The status indicator light 13 is installed at the front side. The green light is on when the fee display is in normal use, and a red light is emitted when a fault occurs in the fee display to alert the user or maintenance personnel. A lighting lamp 14 is also embedded inside the front side of the mounting plate 1 and below the status indicator light 13. The lighting lamp 14 can provide sufficient lighting to help identify vehicle information in a dimly lit environment. A base plate is fixedly connected to the bottom of the mounting plate 1, and a plurality of through holes are symmetrically and equidistantly provided inside the base plate. The base plate with a larger supporting area can better support the body 2. At the same time, the through holes facilitate the installation of the fee display.

[0032] Working principle: When the display screen 3 needs to be cleaned, the motor 10 drives the roller 9 to rotate, and the rotating roller 9 can realize the lowering of the rope 11, so that the brush 7 can fall freely under the action of gravity, and the brush 7 can clean the display screen 3 when it contacts the surface of the display screen 3. When the brush 7 is at the bottom, the motor 10 drives the roller 9 to rotate in the opposite direction to realize the winding of the rope 11, so that the brush 7 can move upward to repeatedly clean the surface of the display screen 3, ensuring the cleanliness and transparency of the display screen 3, so that the user can clearly see the content on the display screen 3, and improve the user experience;

[0033] By setting the MBI5034 driver chip, control circuit, shift register and SDO output pin, the display module where the fault point is located and the specific coordinate position on the module can be located, so that maintenance and user personnel can quickly locate the fault point and easily find the fault point and carry out repairs.

[0034] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
