The hazardous waste weighing and coding system is equipped with a PDA terminal, which has the functions of automatically obtaining weight, removing the peel, and printing labels. The system automatically generates an inventory ledger, scans and submits for out-of-stock, automatically generates an out-of-stock list, and uses the IoT handheld terminal to operate the transfer. It can modify the warehouse and position attributes of the already-inventoryed hazardous waste, provide inventory checking function, offer the function of reprinting labels for missing labels, and for the already-out-of-stock hazardous waste, batch scanning of the QR code for submission can return it to the inventory status, and scanning the QR code can query the relevant information of the label.

The hazardous waste weighing management system is used for weighing the incoming waste materials, printing the corresponding order information, and verifying the waste data information; the processing unit is used to determine the processing method of the waste materials, either for direct processing or temporary storage; the warehousing unit is used to bind the pallets based on the appearance and automatic weighing of the waste materials, and generate ID codes for each pallet; the sensing unit is used to track and manage the circulation of waste materials within the factory, and to monitor the disposal status, location, inventory quantity, and storage time of the waste materials in real time; the size detection unit is used to determine whether the dimensions of the bound pallets are placed in different warehouses. The ID code of the hazardous waste weighing management system is bound to all the information of this pallet, including the source of the waste, the time of warehousing, the detection information, the position status, and the warehouse included in the size detection unit, which includes ordinary warehouses and vertical warehouses. The out-of-storage unit issues instructions according to the plan to guide the out-of-storage work; the incineration and recycling unit is used for the incineration of waste materials and the return of remaining waste materials for storage.

The Read the code weighing system realizes the automatic control of the whole system through the electronic scale, the weight is picked up through the pressure weighing module, and the weight signal is picked up for the transmission process and control requirements, including control scanning, coding equipment, printing equipment and other linkage work.
