摘要
为了解决智能楼宇控制点种类和数量多的问题,设计了基于嵌入式技术的智能楼宇控制系统,系统采用MODBUS通讯协议,485/232总线结构,最大通讯距离达1 200 m,通过区域控制器与控制模块数目自由组合组成控制网络的方法成功解决这个问题,效果良好。
In order to solve problem that the control points of intelligent buildings varies and quantity are large, this dissertation presents a design of the control system of intelligent buildings based on embedded system techniques. The system uses a MODBUS protocol, 485/232 bus structure, freely combines district controllers and control modules to form the control network which covers a maximum communication distance of 1200m. Now the system functions well.
