| Abstract: | The protection system of light-beam formed emission and receiving of infrared ray is introduced.The safety network formed by emission and receiving of infrared ray may conduct the function of safety by its blocking light function.To improve the system anti interference characteristics,using modulation infrared ray ,after processing the received signal,the receiving device is able to make a electrical relay work and gives an alarm and protection. In this paper,the fundamental principles of work are introduced and the main framework is given. |
