Multipoint Nondestructive Temperature Monitoring System Based On Single Chip Microcomputer

Along with the rapid development of computer technology and the continuousdevelopment of embedded technology, temperature monitoring system for demand moreflexible, which need temperature monitoring system can be used in the environment ofpeople is not suitable for long-distance monitoring of temperature, based on Internettechnology at the same time, through Web pages can achieve real-time monitoring ofenvironmental temperature changes. In this paper, based on the actual situation of thecurrent remote temperature monitoring system development, analyzing the problemsexisting in the remote temperature monitoring system, based on embedded technology andcomputer technology to build a remote monitoring system of temperature based on theInternet, allowing users use the Internet browser to log in the Web browser, implement theremote monitoring for temperature field data.In this paper, the main research contents include: the Ethernet technology researchstatus at home and abroad, Ethernet technology, expounds the characteristics of wirelesssensor, Compares the different solutions for home and abroad, based on this, puts forwardthe overall design of embedded Web Server-hardware and microcontrollers, wirelesstransceiver module, network controller, power supply module hardware design has carriedon the detailed discussion and analysis of the problems need attention in the circuit design.Analysis the Nut/OS operating system, the kernel is the main thread, thread scheduling,memory management, and I/O management are included. Based on TCP/IP protocolanalysis, on the basis of based on the practical application, describes in detail the HTMLlanguage, HTTP protocol, the sockets mechanism, CGI technology such as Web-Serverimplementation of the core technology. Test hardware related to the development board, and then detailed analysis, and then the transplant Ethernut steps, the final test and the briefanalysis of the monitoring interface of the whole system.Through the study of this article, development and design the Web Server based onthe embedded Ethernet multipoint temperature monitoring system hardware devices.Equipment includes internal circuit and peripheral circuit, PCB board and developmentboard, etc. Use the Socket Socket mechanism, in the common gateway CGI technologyand the application layer based on HTTP protocol, using C language programming, callingfunction and the underlying control function and so on, thus can realize the multipointtemperature measurement based on Web Server remotely. Based on wireless sensornetwork technology, through the SPI interface on the wireless data acquisition andreceiving control implementation, using GCC programming language, acquired at thebottom of the control function. A static page of the home page design is based on the Front-page software with a combination of HTML language, and CGI programs with HTMLtogether complete the design of dynamic pages. In the operating system configuration,production operating system library function and test the application, the software is to useEthernet and WinAVR compiler.
