Title The design of simple discrete target positioning system of flexible transmission
Abstract According to the requirements of simple discrete target positioning system of flexible transmission ,this paper designs a practical system scheme from hardware and software. An applicable principle control circuit is built by choosing cheap and suitable components.And the programmable logic controller (PLC) of Siemens S7-200 and the photoelectric detection circuit are used to control the operation of the two-phase four-wire hybrid stepping motor of 86BYG603AA, so as to locate and transmit the target points in the synchronous belt transmission system, whose speed is about 0.2 meters per second, and to make the uncertainty of positioning transmission is less than 0.5 mm. The Photoelectric detection circuit is composed of trough type photoelectric switch and some peripheral circuits. It is capable of detecting whether objects could reach the specified location and inputting signals to the PLC. This paper involves the selection and use of the Siemens S7-200 PLC, stepper motor, and stepper motor drives, and the selection of required components for photoelectric detection circuit and its building and so on.
Keywords: photoelectric detection circuit, S7-200 PLC, two-phase hybrid stepping motor.
