In the embodiment of the present invention, the vehicle weighing system includes a weighing device 10 and a vehicle self-weighing sensor 12. Compared with the vehicle self-weighing sensor 12, the weighing device 10 can be understood as an external weighing device of the vehicle, exemplarily , The weighing device 10 can be a truck scale (weighbridge). The unpacked mass of the vehicle can be obtained by using the weighing device 10 , which is the sum of the curb mass (that is, the mass of the vehicle when it is unloaded) and the loaded mass. The second load mass of the vehicle can be obtained by using the self-vehicle load cell 12; then, the second data processing device (related to the vehicle self-load sensor 12) is calibrated according to the difference between the first load mass and the second load mass. Like this, improved the accuracy of the data in vehicle's own load cell 12 and the second data processing device 13; Simultaneously, the data of external weighing device 10 and vehicle's own load cell 12 can intercommunicate, set up a unified platform, improved the practicality of data and improve the value of data use.

In one embodiment, the weighing device 10 is also used to send the package quality to the first data processing device 11; the first data processing device 11 is also used to send the first load quality to the processor 14; 12 is also used to send the weighing sensing information to the second data processing device 13 . The first data processing device 11 and the second data processing device 13 have the functions of data collection, processing, analysis, sending and receiving. In one embodiment, the first data processing device 11 can communicate with the weighing device 10 (such as a weighbridge) by wire, and the first data processing device 11 and the processor 14 can communicate wirelessly. The second data processing device 13 is installed on the vehicle, and the second data processing device 13 and the processor 14 can communicate wirelessly.

In the embodiment of the present invention, the vehicle's own load cell 12 is mounted on the vehicle, and the load quality of the vehicle can be measured by means of stress or pressure. In one embodiment, the vehicle's own load cell 12 includes an axle pin sensor. In one embodiment, for example, a dump truck detects the load quality through the pressure of a lifting cylinder, and a truck detects the load quality through stress or pressure. The vehicle self-weighing sensor 12 may also detect the load mass of the vehicle in other ways, which is not limited.

The curb weight of the vehicle is the weight of the vehicle when it is unloaded (no cargo). Exemplarily, there are two ways to obtain the curb weight of the vehicle.

In one embodiment, the vehicle weighing system further includes: a vehicle identification device 15, connected to the first data processing device 11, used to identify vehicle information, and determine the curb weight according to the vehicle information, and send the curb weight to the first data Processing device 11. Since the vehicle information is related to the curb weight, the curb weight can be obtained after the vehicle information is recognized by the vehicle identification device 15 .

The vehicle enters the truck scale for weighing, and the truck scale transmits the weighing information to the first data processing device 11, and the first data processing device 11 processes the data to obtain the vehicle's overall mass. After subtracting the curb weight from the curb weight, the first load mass is obtained. Afterwards, the first data processing device 11 transmits the vehicle information and load information (when the vehicle is a mixer truck, the load information may be concrete weight information) to the processor 14, and the processor 14 may be located on a platform.

The vehicle obtains the weighing sensing information of the vehicle from the load cell 12, and transmits the weighing sensing information to the second data processing device 13, and the second data processing device 13 obtains the second load quality after data processing, and then, the second The data processing means 13 transmits the load information to the processor 14 .

After the processor 14 obtains the first load quality and the second load quality of the vehicle, it assumes that the data transmitted by the first data processing device 11 is reliable data, and processes the second data according to the difference between the first load quality and the second load quality. The device 13 performs calibration to improve the accuracy of the data in the vehicle's own load cell 12 and the second data processing device 13 . Taking the first load quality as a reference, the data of the second load quality is consistent with the data of the first load quality.

Understandably, the curb weight of the vehicle may not be obtained through the vehicle information. In another embodiment, the vehicle may enter the truck scale (external weighing device 10 ) beforehand with no load to obtain the curb weight. In this embodiment, a judgment condition can be added to the curb weight, and only when the curb weight does not exceed the preset judgment value, can the value of the curb weight be determined to be valid; Then enter the truck scale to weigh. When the data of curb weight is successful and valid, the vehicle is loaded with a load and enters the truck scale again to obtain the curb weight of the vehicle after loading. When the vehicle is a mixer truck, the load is concrete.

After the vehicle leaves the truck scale, the second data processing device 13 is used to feed back load information to the platform (including the processor 14 ) in real time to monitor the vehicle load. When abnormal conditions such as vehicle overload or load reduction (abnormal unloading) are found, an alarm message will be sent to the platform immediately to remind the management personnel to immediately verify whether the vehicle has any abnormal load such as overloading or abnormal unloading. That is to say, after calibration, the real-time monitoring of the load quality of the vehicle can be realized by using the vehicle's own load cell 12 and the second data processing device 13, so as to avoid abnormal situations such as overloading or unloading of the vehicle, and improve safety.
