基于嵌入式计算机网络灯光控制系统

51单片机采集现场调光信息,PCI04嵌入式计算机通过网络传榆调光命令,控制现场灯具发光.回传灯具的发光状态信息,在本机LCD并且通过网络传输到监控主机显示和报警.介绍网络灯光控制系统组成、工作原理和实现方法.重点说明系统调光命令的发布过程和实时性;给出51单片机与PCI04并行软握手的信号、相互配合方法和数据传输过程;深入分析DOs应用程序与Windows应用程序通过网络进行数据交换的方法.

Net light control system based on embedded computer

The 51 single-chip microcomputer collects the on-site lighting control information,while the PC 104 embedded computer transmits the lighting command through network to control the on-site illumination of the lamps and feeds back the information of the lighting state to the LCD of the local computer which is transmitted to the monitor computer through network for display and alarm.The composing,principle and realizing method of the net lighting control system is introduced.The process to give the system lighting com- mand and the real time are emphasized on:the information of the parallel soft handgrip,the cooperation method and data transmission process between the 51 single-chip microcomputer and the PC104 embedded computer are explained,the method of data exchange be- tween the DOS applications programming and Windows applications programming by net are analyzed deeply.
