The temperature and humidity acquisition terminal and the data coordinator. Third, in the software design of the lower computer, according to the hardware configuration of the system, the writing and debugging work of each module program is carried out first. After the debugging is successful, the main program is compiled and debugged, and the software design of the temperature and humidity acquisition terminal and the data coordinator is completed. The program of temperature and humidity acquisition terminal is developed on the IAR EW430 software platform in C language. The program of the data coordinator is developed on the RVMDK3.8A software platform. Fourth, the software design and system debugging of the monitoring client are carried out. The monitoring client is designed on the Visual Basic 6 software development tool. In the writing of monitoring client software, the network communication function is realized by configuring Winsock. Finally, the system debugging platform is built. The platform is composed of temperature and humidity acquisition terminal, data coordinator and monitoring computer. The designed target is achieved through the debugging results, and the feasibility of the scheme is proved. The final part of the thesis is the conclusion department. After the preparatory work, the system design phase and the system debugging, the shortcomings of the system are analyzed and summarized. The main improvement directions are as follows: (1) improving the function of monitoring client software, realizing intelligent analysis data, and recording the temperature and humidity data of each test point into the professional database; (2) designing mobile client software, Users can use mobile phone, Pad and other devices to observe the temperature and humidity data of each test point in real time, increase the means of monitoring, and facilitate the monitoring of the testing personnel; (3) improve the anti-interference ability of the system; (4) expand the scope of the network, make a wireless network between multiple data coordinators and enlarge the monitoring range.
