[0019] The technical solution of the utility model is further described in detail below in conjunction with the accompanying drawings. Example 1

[0020] Reference Figure 1 , an intelligent weighing system suitable for materials in different forms, an intelligent weighing system suitable for materials in different forms, including a floor scale 1, a monitoring camera 2, a license plate recognition camera, a terminal device, a handheld device and a cloud server 11, the floor scale 1 is wirelessly connected to the cloud server 11, the monitoring camera 2 is arranged at one end of the floor scale 1, and is wirelessly connected to the cloud server 11, the license plate recognition camera is arranged on one side of the floor scale 1, the terminal device includes a terminal camera 5, a terminal display screen 6 and a terminal NFC sensor 7, the terminal camera 5 and the terminal NFC sensor 7 are both arranged on the terminal display screen 6, the terminal camera 5 can perform face recognition and QR code recognition, the user swipes the card to sense and recognize, and obtains the user's identity information, the terminal display screen 6 is connected to the floor scale 1 through a serial port line 8, and is wirelessly connected to the cloud server 11; the handheld device includes a handheld display screen 10 and a handheld printer 9, the handheld display screen 10 is signal-connected to the handheld printer 9, and is wirelessly connected to the cloud server 11, the order can be priced and the information is supervised on the handheld device, after the order is completed, the ticket is issued through the printer, and the payment and settlement are completed.

[0021] The handheld display screen 10 is a touch display screen.

[0022] There are two license plate recognition cameras, namely a left license plate recognition camera 3 and a right license plate recognition camera 4. The left license plate recognition camera 3 and the right license plate recognition camera 4 are arranged on one side of the weighing scale 1 through a support rod. The left license plate recognition camera 3 and the right license plate recognition camera 4 are symmetrically arranged about the mid-vertical line of the weighing scale 1 to perform all-round recognition according to vehicles coming from different directions.

[0023] When using, Figure 2 As shown, the following steps are included:

[0024] S1. Suppliers with recyclable materials come to the factory for weighing, including three situations: users without vehicles, vehicles without license plates, and vehicles with recognizable license plates. The license plate recognition camera on the side of the weighbridge 1 first scans whether there is a license plate. If there is a license plate, the license plate information is recognized and weighed. The captured image of the surveillance camera 2 and the reading of the weighbridge 1 are recorded to generate an order. The order includes the license plate information, the captured image, and the weighbridge reading. If there is no license plate, the supplier needs to perform identity recognition;

[0025] S2. The situation where there is no identifiable license plate includes the weighing of a single material and the weighing of a vehicle carrying goods. The supplier needs to go to the self-service weighing terminal to provide identity information. The self-service weighing terminal can accept four methods for identity identification: face recognition, NFC card induction, mobile phone number input and QR code recognition. After identifying personal information, the weighing will be carried out, and the captured images of the surveillance camera and the readings of the scale will be recorded to generate an order; the order includes identity information, captured images and scale readings;

[0026] S3, the generated order is uploaded to the cloud server 11, and the administrator can view the order information on the handheld device;

[0027] S4. After the supplier has completed the weighing, the goods are unloaded, and the administrator fills in the order information. If it is a single material, select no tare, select the corresponding material type, price, and deduction points to complete the settlement. The handheld printer 9 issues a ticket to complete the settlement. According to the calculated summary, the supplier's material price is paid; if it is a cargo vehicle, select tare, select the corresponding material type, price, and deduction points, and complete the information filling. The order is in an unsettled state and waits for the tare to be weighed;

[0028] S5. If the vehicle is carrying a single type of material, after the supplier has finished unloading, the vehicle is driven back to the scale for weighing again, and the vehicle is weighed again through license plate recognition or self-service weighing terminal equipment to log in the identity information;

[0029] When S6 recognizes the license plate and obtains the identity information, it will compare it with the license plate or identity information of the existing order to determine whether it is the first weighing or the second weighing. If there is no weighing record, it is the first weighing and a new order is generated; if there is a weighing record, it is the second weighing. After the weighing is successful, the administrator needs to use the handheld device for further operation;

[0030] S7. The weighing information of the second weighing, including the images captured by the monitoring and the readings of the scale, are all attached to the original order information. The administrator chooses whether to weigh the empty truck for the order information that has just been weighed based on the actual situation. If no is selected, that is, the vehicle carries multiple items, it needs to be weighed each time it is unloaded. The administrator continues to fill in the information of the materials to be unloaded on the handheld device to realize the unloading of multiple items. If empty truck weighing is selected, all materials are unloaded, the order is subtracted according to the readings of the scale, the material type is calculated, and the total price is automatically calculated based on the material price and deduction point selected by the administrator, and the settlement is completed and the ticket is printed.

[0031] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
