| Abstract: | Incremental photoelectric encoder is a digital angle measurement device in combination of light, machinery and electricity. Programmable controller, as an electric controller monitored by digital operation, is an important, extensively used industrial controller. PLC and photoelectric encoder were adopted to monitor the angle of the awning in the Reconstruction of the art plaza for Expo'99 KunMing. Some measures were taken to deal with problems such as the smallness of corner, heavy weight and vibration of the awning over the auditorium. The project has already been put into use and it has been proved that the measures taken were easible and valid. |
