摘要
在昆明世博园艺术广场改造工程的雨蓬开启监控系统中 ,采用了 PLC和光电编码器进行角度监控 ,并针对观众席雨蓬小转角、大重量和易产生振动等问题进行了一系列处理 .经实践证明 ,采取的相应措施可行。
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.
