Study on environmental noise remote monitor technology based on CDMA networks

According to corresponding criterion and method of environmental noise measurement in china, the paper puts forward a kind of environmental noise remote monitoring terminal based on CDMA wireless technology. The remote monitoring of the environmental noise, history data reviewing, super scale noise alarming and field saving can be realized. The frame of the whole system, the makeup of hardware and scheme of software is introduced. The key module of the hardware and software, method of data processing are discussed in detail. The real time value and chart of noise data from the terminal is demonstrated in the end.
