Design and Development of Industrial Process Control System Based on Wireless Network
Guo Jianli, Shi Huiyuan, Wang Jie, Su Chengli
Abstract484)   HTML    PDF (2212KB)(202)      
In this paper, the wireless communication network is established based on wireless communication equipment based on wireless network control technology. The wireless process control strategy for tank and high temperature furnace are designed, and the predictive function control (PFC⁃PID) and generalized open⁃loop response (GORC⁃PID) strategies are proposed respectively. Based on the requirement of task, the configuration of software and hardware for wireless industrial process system is achieved. On basis of this, the modelling of dynamic mathematic model of system and engineering configuration are completed. Finally, the industrial process control system based on wireless network is developed with the water tank and high temperature heating furnace of the National Local Joint Engineering Laboratory of Petrochemical Process Operation Optimization and Energy Saving Technology as the experimental device and the configuration software of Microwave Command Guidance System (MCGS) as the development and verification platform. The control results show that the developed wireless industrial process control system can control the level of tank and temperature of high temperature furnace effectively. It can avoid the drawback of wired communication at the industrial filed and has a very high industrial value.

Ansys Analysis of Rubber O-Sealing Ring
WANG Jie, XIE Yu-jun
Abstract508)      PDF (387KB)(578)      
By utilizing finite element analysis software ANSYS, a finite element model for rubber O-sealing ring and its boundry was set up.The change of shape and stress distribution under different oil pressure and initial compressibility was analyzed, and the relations between maximum contact stress, oil pressure and initial compressibility was deduced. Then the position of possible crack was described , which is a theoretical basis for reasonable installation and use.
