摘　　要：针对当前实验室管理的不足,提出基于嵌入式技术和无线网络的多终端监控系统设计。该系统包括采集前端、数据处理中心和客户端3部分,通过无线网络实现通信。基于LPC11C14的采集前端采样传输实验室环境信息,接收并执行控制指令。数据处理中心提供了两种环境信息存储方式并根据需要向采集前端发送控制指令调节现场工况。客户端负责对实验室的监控,管理人员通过访问Web服务器或LabVIEW上位机程序实现。考虑到可靠性需求,设计了LED、蜂鸣器等声光报警措施,并在发生异常状况时短信通知管理人员。测试表明:设计的监控系统运行稳定,能较好满足实验室的监控需求,可靠性措施提高了系统的实用性,具有一定的应用价值。Aiming at the deficiency of current laboratory management in College,a multi-terminal monitoring system based on embedded technology and wireless network is proposed.The system consists of three parts:acquisition end,data processing center and client,and realizes communication through wireless network.Based on LPC11C14,acquisition end sampling and transmit laboratory environment information,receive and execute control instructions.Data processing center provides two kinds of environmental information storage methods and sends control instructions to acquisition end to adjust laboratory condition according to the requirements.Client is responsible for the monitoring of the laboratory,and is realized by accessing Web server or LabVIEW upper computer program.Considering the reliability requirements,LED and buzzer sound and light alarm measures are designed,and manager is informed by short message when abnormal conditions occur.Test shows that the designed monitoring system runs stably and can meet the monitoring requirements.The reliability measures improve the practicability of system and has center application value.
