Design and Development of New Auto-Detecting Platformfor Hoists of Suspended Access Platform
A new detecting platform has been designed and developed to improve the performance of suspended access platform’s hoists in the paper. The new platform consists of a mechanical and control piece. The core control system is designed based on S7-200PLC and VB6.0; Computer is a superior machine and S7-200PLC is an inferior machine in the system; VB6.0 is used in the superior machine as the development platform. Testing data will be saved into Excel2000 by using VB's OLE automation technology; and in the VB environment, using OPC standard drive will complete real-time data communication between superior and inferior, also complete data processing at the same time. Therefore, Man-machine interface and reliable control system can be built. The inferior computer can achieve running and testing process control of hoists and collect the data of tension, vibration and temperature of hoists. The practical application of the platform shows that the system can well reduce the time costs and improve test results’ inaccurate of existing detection methods. The detection efficiency is improved; the labor intensity of operators and the running costs of produces are reduced, greatly.
