LabVIEW的生态环境监测系统开发+源程序(2)

Real-time monitoring of the ecological environment of humidity, temperature, PM2.5 and other parameters of the system is the main task of development. This article from the lower computer detection system hardware module, software and PC monitoring system part of the detailed.

The detection system of the lower computer involves a variety of sensor parameters of the sensor components, monitors and microcontroller microprocessors. Fromthese hardware, we have developed and designed the parameters of the microcontroller control sensor for the detection of eco-environmental parameters of the detection module for the display of test data display module and between the upper and lower computer for data communication RS232 Serial communication module. In the detection system design hardware module at the same time, but also through the use of keil software on the next machine hardware modules designed the corresponding software program.

PC monitoring system based on the use of LabVIEW graphical programming language design PC program, the preparation of the host computer program is mainly used to read the serial data, the data analysis shows that the limit alarm. In addition to the establishment of the ecological environment monitoring system back-end database, the detected data in real- time preservation. The human-computer interaction interface has been carefully designed to make it practical, beautiful.
