Abstract: The raw material berth of Chongqing Iron and Steel Co., Ltd. is in the form of slope, and the traditional method of water scale settlement is adopted. The major errors come from the poor vision of water scale, the change of water temperature and water density, and the ballast, with a basic deviation of 2%-5%, which has a huge impact on the quality deviation of coal or ore transportation. Leading to large deviation of coal - burning data to bring large economic losses.With magnitude 0.2 high precision intelligence control matrix modification of belt scale, high precision, high accuracy, high stability, with double set of high-precision belt scale continuous installation, data than each other, and intelligent software will high-precision belt scale remote control, real-time online monitoring of belt scale operation, ensure the belt scale always stay 0.2 accuracy. At the same time, the data is connected to the management system of Chonggang, which is connected with PLMS and PSCS to achieve accurate trade settlement.
