What are the common cheating methods in truck weighing using weighbridges? How does the unmanned weighbridge system prevent cheating?

At locations such as mines, factory entrances and exits, warehouses, and port terminals, weighbridges are used to weigh trucks carrying goods, in order to determine the load weight, prevent truck overloading, and use the weighing results as a basis for settlement.

However, during the actual weighing process, cheating can occur when using weighbridges alone. This includes:

(1) installing remote control devices on older sensors to alter the weighing data;

(2) collusion between truck drivers and weighbridge operators;

(3) manipulating the truck's stopping position so that the wheels do not fully rest on the weighbridge, thereby increasing or decreasing the net weight of the goods;

(4) swapping license plates between two trucks with different tare weights, loading different priced goods after weighing the tare weights, and causing a loss of difference. Such cheating behaviors using weighbridges seriously damage the economic benefits of enterprises and reduce management efficiency.

To eliminate the phenomenon of trucks cheating using weighbridges, unmanned weighbridge systems should be utilized in scenarios where weighbridges are used to weigh trucks. This upgrades the simple weighing function of weighbridges into a comprehensive weighbridge anti-cheating management system with complete control functions, improved anti-cheating measures, and smooth information communication.

Anti-cheating measures of the unmanned weighbridge system:

1. The system is equipped with RFID radio frequency (or Bluetooth automatic identification) and infrared monitoring functions, which can automatically identify vehicle information such as vehicle tare weight, owner information, license plate, and type of goods carried, effectively preventing the swapping of license plates and smuggling.

2. Cameras are configured for image and video monitoring to prevent license plate swapping during the vehicle weighing process, prevent weighing without the driver exiting the vehicle, prevent situations where the front or rear wheels of the vehicle do not fully rest on the weighbridge or press against each other, and prevent collusion between weighbridge operators and drivers, thereby deterring misconduct at the weighing site.

3. Intelligent voice guidance during the weighing process ensures that if the vehicle is not within the specified stopping range, weighing cannot proceed, avoiding the driver's attempt to cheat by manipulating the wheel's stopping position.

4. Infrared positioning devices are installed. If the vehicle is not properly positioned, the system automatically prohibits weighing and provides a reminder.

5. The system is equipped with intelligent barriers. If the vehicle does not complete the weighing process correctly, it cannot pass through the barrier.

6. Real-time monitoring of the weighbridge remote control system is conducted. Once a remote control cheating phenomenon is detected, the system automatically alerts and records it.

7. All weighing data is automatically transmitted and recorded over the network, allowing managers to view the weighing data in real-time, monitor the weighing process, and prevent the issuance of fake tickets.

8. The system software has strict permission management. Only personnel with relevant permissions can modify the weighing data. The system not only records the weighing data but also the image monitoring data.

Through these comprehensive anti-cheating measures, the adoption of the unmanned weighbridge system effectively prevents various cheating phenomena. From the perspective of practical application effects, the effectiveness of the system has indeed been verified, thereby safeguarding the economic benefits of enterprises.

Additionally, the unmanned weighbridge system improves weighing efficiency, achieves unmanned operation, reduces manual input in enterprise cargo weighing, provides comprehensive monitoring of the entire weighing process, and enhances enterprise management efficiency.
