嵌入式远程集中测控系统的设计与实现

为实现对远端分布式现场设备进行测控,提出了一种基于嵌入式平台和无线通信技术的解决方案。该方案采用客户/服务器方式实现远程集中测控,在嵌入式平台上,利用通用网关接口(CG I:Common GatewayInterface)实现W eb服务器和分布式现场的测控应用程序接口;通过PTR2000无线传输模块,采用轮询的方式进行测控信息的搜索和分发;在客户浏览器中下载且运行Java App let应用程序完成测控信息传递。现场测试结果表明,测控执行部件对现场温度的采集和显示设备的控制是实时、高效、可靠的,测控系统设计方案合理,开发成本优于同类相关技术。此系统也可以应用于其他远距离分布式控制场合,并为嵌入式系统的网络应用提供了参考。

Design and Realization of Centralized Remote Monitoring and Controlling System Based on Embedded Technology

In order to realize the monitoring and controlling the equipments on the remote distributed spot with high qualities,a method based on embedded plat and wireless telecommunication technique is proposed.The system is based on the Client/Server model,through the CGI(Common Gateway Interface),mutual interaction between the applying program interface on scene and Embedded Web Server is established.By using the wireless module PTR2000 the information searched and distributed is realization in turns.The browser downloads and runs Java Applet through Java applet environment,data transmission and command control to the remote wireless module can be carried.The test result show that,this system succeeded in gathering the temperature on the spot and controlling the remote display terminals with high efficient and achieved good result on reliability,meanwhile the system provided a reference of using embedded system in the network application.
