Design and Research of Crop Physiological Parameters Detection System Based on WSN

Abstract

It is of great significance to obtain the physiological information of stem and fruit diameter, chlorophyll content and plant stem flow of crops to guide the fertilization and irrigation of agriculture. Aiming at problems of insufficient method of real time detection on plant physiological parameters in traditional agriculture, a new type of crop of physiological parameters detection system based on wireless sensor network (WSN) is designed. The data acquisition of the system uses the IAR platform to build the ZigBee wireless sensor network, and the wireless sensor nodes are designed based on the CC2530 chip for acquisition and transmission the physiological parameters of the plant. The remote transmission of the system uses the ARM9-based CDMA DTU module to send the data through the CDMA2000 and the Internet network to the remote detection center. The detection center can collect the data and query the historical data in real time by the upper computer software written by LabView and SQL Service. The data indicators to determine the analysis. The experimental results show that the system has high accuracy and stable data transmission to meet the design requirements.
