The Design And The Implementation Of Carbon Dioxide Remote Monitoring System Based On CDMA

With increasing low-carbon environmental awareness and continuously improvethe environmental requirements of the international community to a low-carbon,carbon dioxide and other carbon-containing gas detection become increasinglyimportant. Enable government and personal understand the carbon dioxide ofatmosphere around and some other places, this article using micro-controllertechnology, data acquisition system,CDMA wireless transmission system to achievecarbon dioxide remote monitoring.In this paper,under the basic of in-depth study of automatic control and carbondioxide monitoring.By using CDMA communication technology to achieve thewireless remote monitoring of the carbon dioxide and using ATMEGA128microcontroller to collect the data,using CDMA DTU KS-93C wireless transmission unitto connect serial data acquisition unit and then transmits data to a remote monitoringterminal. And BAIDU map can offer free API interface to the programmer of the thirdparty, the programmer can use BAIDU map to locate the GPS and the IP address tosolve the problem of the locate the device.In this paper,with the background of the actual monitoring application, microcontroller detects carbon dioxide, temperature and humidity and GPS information,using CDMA transmission module transfer data via CDMA communication link toremote monitoring center unit,using C#to write the windows body application ofmonitoring center unit and parses the data transmitted over the network to achievereal-time monitoring.Moving BAIDU satellite map to the windows application body,realizing locate the device on the map and using database for the third party to haveaccess to the data in the system, it shows it can realize the data monitoring and locatethe device on the map,realizing the integration of the data and the spatial locationmonitoring.
