Research On Intelligent Protection And Control System For Belt Conveyor

Belt conveyor is a transportation equipment with continuous of traction pieces. It is the most important aspect of the modern transportation system, which is widely used in fuel transport, metallurgy, mineral separation, chemical industry and other fields. It is important to protect belt conveyors of burning coal transport in various transportation systems. At present, there is no highly automatic, intelligent or sound protection measure in the belt conveyors transmission coal system of Jiujiang Petrochemical power plant. For this reason, a sort of intelligent protection system for belt conveyors is designed in this thesis.The system is mainly composed of two parts: that is the detecting part and the monitoring part. The detecting part is an intelligent instrument made by the author and his partners, and the core of intelligent instrument is made up of low power MCU MSP430F149 of TI Corp, which is mainly responsible for collecting voltage, current, and belt speed and other parameters of the traction motors. In addition, the belt speed is regulated by fuzzy control algorithm so that it remains within the scope permitted. Once it goes beyond the set value, the motor will be stopped to protect the belt. The monitoring part is designed with kingview6.51 with its friendly interface. Its functions include signal collection, fault alarm, automatic report generation and printing, and a help system etc, which enable it to dynamically manage and control all monitoring parameters so as to meet the needs of users. The meter software is developed with C language and fuzzy algorithm. Its whole structure is programmed with module so that the system functions can be conveniently increased or decreased. The communications between intelligent instrument and PC is made possible with ADAM module's protocol and based on RS485 bus.The application has proved that the protection system can improve intelligent degree of the whole burning coal transport and ensure stability and security of the power plant, and that all its functions have met the design requirements. The system won the user's satisfaction and recognition with its flexible operation and friendly user-computer interface. In addition, the system is of some reference significance to other projects and there is a bright market for the successfully developed intelligent instrument.
