摘　　要：针对目前楼层照明中存在不易管理、能源浪费等问题,利用虚拟仪器技术设计了一种可对多路电气设备集中控制的系统,该系统由RS-485总线连接各个下位机,下位机系统利用单片机控制继电器的通断,上位机程序使用LabVIEW编写,可以修改下位机的系统时间、工作时间段以及温度上限等参数,读回温度值和工作状态。该系统具有硬件电路简单,通信可靠等特点,系统兼具楼层温度监测功能,可为火灾预警提供支持,具有广泛的应用前景。For the questions of difficult management and energy waster in the floor lighting,this paper designs a centralized con- trol system of multi-channel electrical equipment based on virtual instrument technology.Lower machines are connected to- gether to form a complete control system using the RS-485 Bus,SCM is used to control the relay in the Lower machine systems.The host computer program written using LabVIEW,the user can modify the system time,working time and upper temperature limit,read back to the temperature and working conditions.The system has the characteristics such as simple hardworking circuit and reliable communications.
