The Internet of Things electronic floor scale is mainly designed for enterprises to conduct measurement management during the processes of raw material procurement, finished product sales, and material transportation and allocation within the factory. The communication interface of the weighing instrument is RS-485(MODBUS-RTU), while the serial communication port of the machine is RS-232C. Communication between the two requires an SC-09 adapter cable. The pin definitions of the same type of communication interface on different devices may vary.

RS-485 and RS-232C are two different standard serial data interfaces. The main difference between them lies in the different signal transmission methods. The RS-232C standard transmits signals by utilizing the voltage difference between the signal line and the common ground wire, and it adopts a unidirectional transmission mode. The RS-485 standard transmits signals based on the voltage difference between transmission lines and adopts a differential transmission method. The SC-09 cable enables the conversion between these two different signal transmission methods.

Electronic floor scales and monitoring systems that respectively form upper and lower computers are widely used in industrial control. Directly realizing serial communication between the electronic floor scale and the machine saves costs and simplifies the system, which has great practical value.

The customized weighbridge weighing solution for enterprises, the mine and the weighbridge room are far from the management department. The management personnel cannot understand the working status of the electronic weighbridge in real time, and the weighbridge operation work is also not effectively controlled.

The remote centralized weighbridge Weighing system is an upgrade based on the original weighbridge management software. The system is equipped with a network high-definition camera. The video capture is connected to the weighbridge management software. On the system interface, the captured pictures of the weighing site, vehicle numbers, weights, materials and other information can be displayed on the same screen. The weighing site images and weighing data are corresponding and stored in the database for future reference and viewing at any time.

The comprehensive management department has established a "remote centralized weighbridge weighing system". By setting up a data service center, it connects the weighbridge room with all its affiliated departments, including the entry and exit yards/stations and transfer stations, to complete the weighbridge management system for goods measurement. The data generated by each department is transmitted through the network and stored in the server to achieve data sharing. It is convenient for enterprise managers to conduct statistical analysis, verification and proofreading of data, and promptly grasp relevant metrological information, which is conducive to the control and management of the metrological link. The weigher can also check the weighing status of the vehicle through the weighing software interface.

The remote centralized weighbridge weighing system, based on the new generation of communication technology, management concepts, and the industry characteristics of mineral product production and sales, and in accordance with the idea of precise management, helps group enterprises achieve the goals of decentralized weighing in weighbridge rooms across regions, centralized management of weighbridge drivers, and prevention of cheating, solving the weighing management problems of group companies.
