The forklift Electronic scale uses the RFID weighing technology of the Internet of Things, GIS technology and cloud computing to realize the visual positioning management of the electric forklift operation in the warehouse, so as to manage the goods in the warehouse more safely and efficiently. Through the intelligent guidance of forklift operation, the operation difficulty of forklift operators is greatly reduced, the goods in the warehouse are placed more regularly, the efficiency and accuracy are improved, and the labor cost is reduced. Through wireless network technology, the real-time visual view of forklift operation in the warehouse is realized, and the management of electric forklift operation in the warehouse is strengthened. Through the visual query interface, the forklift weighing operation and the storage state of goods in the warehouse are more intuitive, which is conducive to improving the efficiency of warehouse management and reducing human errors. The mobile workstation adopts touch operation, and the operation form is simpler and more convenient.

The electronic scale of electric forklift adopts the conversion between different signal transmission modes, and the monitoring system composed of electronic scale and PC is widely used in industrial control. The serial communication between electronic scale and PC is realized directly, which saves the cost and simplifies the system, and has great practical value. The customized weighing solutions of enterprises are far from the management department, so managers can't know the working state of electronic scales in real time, and the weighing work is also effectively controlled.

In order to ensure the measurement accuracy of forklift weighing in various environments, linear compensation, zero compensation and temperature compensation, as well as sensing dynamic design are generally added to the bridge circuit of forklift weighing strain gauge. At the same time, in order to ensure the accuracy of remote excitation of the sensor, two wires are generally output to the weighing instrument at both ends of the excitation of the strain gauge to calculate the loss compensation of the excitation voltage during long-distance transmission. When adjusting or replacing the digital weighing sensor and the digital weighing instrument, it is directly adjusted in the weighing instrument without adjusting the angle difference through the junction box, which greatly improves the simplicity of regular inspection and maintenance of weighing and the accuracy of commercial measurement.

The forklift electronic scale adopts sealed junction box, which is dust-proof and moisture-proof to ensure reliable signal transmission. The weighing instrument adopts special industrial process controller, and communicates with the central control room through RS-485 bus, which can be controlled independently and online by PLC. It is composed of computer, weighing module and peripheral equipment, which serves as the man-machine interface of the whole system. Complete all system parameter setting, process monitoring and data recording.
