Research And Application About Trouble Measuring System Of Conveyer Belt

Conveyer belt is a running transportation equipment of motor drives. It can transport material and finished products, using broadly in industry production. In the running production of conveyer belt, there are belt creep, broken belt, tearing, over loading, coupling cut i.e, result in serious consequence. So measuring the trouble is the important. In this paper, studied on the fault detection system of conveyer belt, selected sensors are torque sensor, which is new detection method that is differ from selected sensor former. Using it can detect belt creep, broken belt, over loading, coupling cut of conveyer belt. As far as pulling to one side and portrait tearing, selected pulling to one side sensor and portrait tearing sensor. And introduce performance, lectotype, installation, debugging.From collectivity design software, hardware system is stated detailedly. IN the studing system of conveyer belt, the traditional chip microcomputer system is replaced by Siemens S7-200 PLC control system; the disadvantages of chip microcomputer system are solved, such as complexity of software development process, low ration precision, inconvenient operation and indirect view.In the software construction, the system interface is exploited by Visual Basic that has good visual effect and is easy to be learned. Visual Basic can largely shorten its exploitation cycle, reduce cost, easily be maintained, easy to realize user's user-defined function, create friendly user interface.PC is the high level computer and PLC is the low level computer. PC uses the serial communication component of the visual programmed software VB. This paper discusses how to realize the serial communication by way of PLC free port and build the real time monitor control system.There is direct guiding sense to study on the other trouble measuring system and control system.
