[0001] This utility model belongs to the technical field of weighing equipment, specifically relating to a weighbridge weighing device. Background Technology

[0002] A weighbridge, also known as a truck scale, is a large scale installed on the ground, typically used to weigh the tonnage of truck cargo. It is a primary weighing device used in factories, mines, and businesses for measuring large quantities of goods. Weighbridges can be classified according to their structure: I-beam weighbridges, T-beam weighbridges, L-beam steel weighbridges, U-beam steel weighbridges, channel steel weighbridges, and reinforced concrete weighbridges; and according to their sensor type: digital weighbridges and analog weighbridges.

[0003] Most existing weighbridge systems are unidirectional static weighing systems. As the equipment ages, it is prone to communication failures and data loss. In addition, it lacks anti-cheating functions and cannot meet the independent weighing needs of two-way lanes. Utility Model Content

[0004] The purpose of this utility model is to provide a weighbridge weighing device with a simple structure and reasonable design in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A weighbridge weighing device includes a weighing platform on which two truck scales are symmetrically arranged. Each truck scale is electrically connected to a weighing instrument. Control cabinets are symmetrically staggered at both ends of the weighing platform. An industrial computer is installed inside the control cabinet. A vehicle identification device is installed on the control cabinet, which consists of a touch screen, a camera, and an RFID card reader. A vehicle guidance device is installed on the top of the control cabinet. A wireless data transmitter that communicates in real time with an urban management platform via a wireless network is also installed inside the control cabinet.

[0007] As a further optimization of this utility model, both ends of the weighing platform are provided with ramps, the slope of the ramps is less than 30 degrees, and anti-slip patterns are provided on the ramps.

[0008] As a further optimization of this utility model, a guardrail is provided above the weighing platform between the two truck scales, and the bottom of the guardrail is bolted to the upper surface of the weighing platform.

[0009] As a further optimization of this utility model, the control cabinet is also equipped with a server and a power bank, and the power bank enables the entire device to operate independently for more than four hours when the power is off.

[0010] As a further optimization of this utility model, the vehicle guidance device includes a traffic light device installed on the top of the control cabinet. The traffic light device is electrically connected to the industrial control computer and automatically switches the signal lights according to the weighing status.

[0011] As a further optimization of this utility model, the vehicle guidance device also includes a barrier gate housing installed on both sides of the entrance of the weighing platform. The barrier gate housing is electrically connected to the industrial control computer, and a barrier gate arm is installed on the top of the barrier gate housing.

[0012] As a further optimization of this utility model, the industrial control computer has a built-in anti-cheating module with pairing time alarm and tare weight difference alarm functions.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By setting up two bidirectional weighing truck scales, the loaded weight and empty weight of the vehicle are weighed and compared when the vehicle enters and leaves the factory. Combined with cameras capturing photos of the vehicle's weighing status and barriers preventing two vehicles from entering the weighing platform at the same time, the anti-cheating function of the weighing device is greatly improved.

[0015] 2. Vehicle data, camera-captured photos, and vehicle data are all stored on a server. The server is connected to a wireless data transmitter, which communicates with the city management platform in real time via a wireless network.

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example

[0023] like Figure 1 - Figure 4 As shown, a weighbridge weighing device includes a weighing platform 1, with ramps 2 at both ends of the weighing platform 1. The slope of the ramps 2 is less than 30 degrees, and anti-slip textures are provided on the ramps 2 to facilitate the movement of vehicles onto the weighing platform 1.

[0024] Two truck scales 3 are symmetrically arranged on the weighing platform 1. One truck scale 3 is used to weigh the weight of a vehicle entering the factory with cargo, and the other truck scale 3 is used to weigh the weight of a vehicle leaving the factory empty. The truck scale 3 is electrically connected to a weighing instrument 4, which can display the weighing data.

[0025] A barrier 5 is installed above the weighing platform 1 between the two truck scales 3. The bottom of the barrier 5 is bolted to the upper surface of the weighing platform 1. The barrier 5 is used to isolate vehicles entering and leaving the factory, regulate vehicle weighing behavior, prevent data fraud, and also to divert vehicles to avoid congestion at the weighing platform 1.

[0026] The weighing platform 1 is symmetrically and staggered at both ends with control cabinets 6. The control cabinets 6 are equipped with vehicle identification devices. The vehicle identification devices consist of a touch screen 10, a camera 11 and an RFID card reader 12. When a vehicle enters or exits the weighing platform 1, the vehicle license plate information can be identified by the camera 11, and the card number can be read by the RFID card reader 12, so that the driver does not need to get out of the vehicle to register, saving a lot of time.

[0027] Meanwhile, if the camera 11 and the RFID card reader 12 fail to recognize the license plate number or card number information, the information can also be manually entered through the touch screen 10;

[0028] The control cabinet 6 houses a server 7 and a power bank 9. The weighing instrument 4 and the vehicle identification device are both connected to the server 7. The server 7 is used to transmit identification information, weighing data, and images captured by the camera 11 when the vehicle passes through the weighing station to the server 7 for storage. The server 7 is connected to a wireless data transmitter 17, which communicates with the city management platform in real time via a wireless network. The wireless data transmitter 17 can synchronize data with the city management platform in real time, minimizing the risk of data loss in case of server 7 failure. The power bank 9 is used to provide auxiliary power to the entire device. The power bank 9 enables the entire device to operate independently for more than four hours when the power is off, making it convenient to use the device for weighing during power outages.

[0029] The control cabinet 6 also houses an industrial computer 8. The top of the control cabinet 6 has ventilation holes 13 for cooling the server 7 and industrial computer 8 installed inside. The top of the control cabinet 6 is equipped with a traffic light device 14, which is electrically connected to the industrial computer 8. It can automatically switch the signal lights according to the weighing status. Specifically, when the truck scale 3 is in the weighing state, the red light of the traffic light device 14 is lit to remind subsequent vehicles to wait. When the vehicle weighed on the truck scale 3 leaves, the green light of the traffic light device 14 is lit to guide subsequent vehicles to be weighed.

[0030] On both sides of the entrance to the weighing platform 1, there are also barrier gate boxes 15. The barrier gate boxes 15 are electrically connected to the industrial control computer 8. A barrier gate arm 16 is installed on the top of the barrier gate box 15. The barrier gate arm 16 installed on the barrier gate box 15 is controlled by the industrial control computer 8. When the red light of the traffic light device 14 is on, the barrier gate arm 16 is lowered to block the following vehicles, so as to prevent two vehicles from cheating together. When the green light of the traffic light device 14 is on, the barrier gate arm 16 is raised to allow the following vehicles to drive into the weighing platform 1 for weighing.

[0031] The industrial control computer 8 also has a built-in anti-cheating module with pairing time alarm and tare weight difference alarm functions. The pairing time alarm compares the time of vehicle identification by the camera 11 to prevent vehicles from being weighed multiple times in a short period of time to cheat money. The tare weight difference alarm compares the weighing data of the two truck scales 3 when the vehicle enters and exits to prevent vehicles from increasing the tare weight by hiding people or filling the water tank with water to cheat money.

[0032] It should be noted that in this type of weighbridge, when a vehicle enters the factory, the license plate information or card number information is read by a camera 11 or an RFID card reader 12 installed on one side of the control cabinet 6, and the read vehicle information is stored in the server 7. After the identification is completed, if there is no vehicle being weighed on the truck scale 3, the industrial control computer 8 controls the traffic light device 14 to turn on the green light. At the same time, the industrial control computer 8 controls the barrier gate box 15 to raise the barrier arm 16, so that the vehicle can smoothly drive onto the weighing platform 1. When the vehicle is weighed for the first time on the truck scale 3, the industrial control computer 8 controls the traffic light device 14. When the red light illuminates, the industrial control computer 8 controls the barrier gate box 15 to lower the barrier gate arm 16, blocking subsequent vehicles and preventing two vehicles from colluding to cheat during weighing. After weighing, the weighing result is transmitted from the weighing instrument 4 to the server 7. After receiving the data, the server 7 synchronizes the data in real time through the data wireless transmitter box 17 to the city management platform to avoid data loss. After unloading, the vehicle needs to pass through another truck scale 3 to weigh the vehicle's tare weight and compare it with the weighing data of the vehicle under load to prevent vehicles from increasing their tare weight by hiding people or filling water tanks with water to cheat for fees.

[0033] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
