| Abstract: |
| There are normally electronic cable tunnels in large modern industrial enterprises.According to the real conditions,a wireless distributed supervision system for an electronic cable tunnel of 1 700 meters is built,which is based on the programmable logic controller of S7-200. It controls the ventilator,drainage and fire doors automatically. The system structure and function design are presented,and the wireless communication system and temperature signal processing are introduced. |
