| Abstract: | Aiming at control of switch quantity the method of controlling by communication between supervisory computer and controller board was come up with. A type of controller board with RS485 and modbus interface that takes STC89C51 as its core was designed. Some function comes true,such as collecting single-numbers,controling, displaying,judging and running operations. |
