[Abstract]:With the development of social economy, people pay more and more attention to water resources and water environment. How to reliably and accurately measure the concentration of some main elements in water environment is very important to improve the production and quality of aquatic products. The research of wireless water environment detection system in this paper has important engineering value and theoretical significance. In this paper, the data of remote acquisition node is transmitted to the control center for analysis and processing, which constitutes a water environment detection system. The main research contents and achievements are as follows: (1) the method of ion selective electrode is designed and studied. Ion selective electrode biosensor is used to detect ion concentration. According to the knowledge of ion selective electrode and Ernest equation, the measurement method used in the instrument is obtained, which provides theoretical support for the ion concentration measurement of the instrument, including one point calibration, two point calibration and concentration measurement. (2) according to the characteristics of water environment wireless monitoring device, ZigBee wireless transmission protocol is adopted to realize the data acquisition and data transmission between the receiving nodes in the water environment wireless monitoring device. The CC2530 chip is mainly used. Realize the remote detection and analysis of the upper computer. (3) according to different function modules, the realization of system hardware circuit and the algorithm flow of software design are explained in detail. Finally, the detection results are analyzed. It is proved that the water environment wireless monitoring device has achieved the required function and satisfied the performance requirements. In this design, two main methods are used, one is the touch screen directly connected to the development board, the other is connected to the PC machine, the interface is more friendly.
