The Design Of Cycling Chains Calibration Device Of Electronic Belt Scale

With the widely application of the continuous weighting belt scale in the dock, power station, coal field and anyother important field, it becomes a very heated discussion in the belt weight scale field that how to calibrate the belt scale and its meter more convenient and faster. The old calibration methods have their own defect, and will not fit the Comprehensive requirements. For example, the calibration using the real goods will be a very accurate one, but its process is extremely complex and hard to do it regularly; the calibration using the hang chains and calibration using the chains code will be not very accurate because of its own principle and how it works. Then that appears the cycling chains calibration device.The cycling chains calibration device combine the advantage of real-goods-calibration with unreal-goods-calibration's. It is calibrated by cycling chains, and the belt will carry the cycling chains again and again, this movement ensure its principles and State of motion similar to the real-goods-calibration. And what's more,it eliminates the trouble of the real one. It wil be a automatic control system and can enter or exit the calibration easily. The state departments have certificated that the cycling chains calibration device is the only things that can replace the real-goods-calibration.In this article, the ICS-465C electronic belt scale made by SAIC and its cycling chains calibration device will be introduced. The function and structure of it will be mentioned. This project include the technology of ARM Embedded System Platform, the programming of PLC and Touch Screen.After the ICS-465C electronic belt scale was designed, it has been applied to several dozen large and medium domestic plant. Moreover, it is sold abroad with its cycling chains calibration device. The system has withstood the test of practice, which fits the request of customer at all.
