Research On Intelligent Monitoring Of The Soil Environmental Quality Based On WSN

Synchronization and continuance are required on time to intelligently measure environmentalindex. In other aspects, expanded scope, multi-measuring point, lower costs of manpower andfacilities are also required. The above conditions were hardly met before WSN appeared. Asledge-hammering sort of merit is in WSN: higher precision, lower cost, real-time, high capacity,intelligent, real-time monitoring and wide coverage, with which, real-time automatic measuring,automatic transferring and visual showing are becoming available. Its advantages ofself-organization and fault-tolerance can help avoid the collapse of the whole system that causedby the death of some nodes. Key is that it can also be used in harsh environments, theseadvantages make wireless sensor network (WSN) is widely used in the field of environmentalmonitoring.Based on the fully research on environmental monitoring system and WSN, a solidenvironment monitoring scheme based on wireless sensor network is proposed. In jiangsuprovince baoying’s artificial poplar monitoring area, many node were placed by multiple nodes,and network in multiple ways, to realize environmental indicators in monitoring area ofintelligent acquisition, long time dynamic monitor, remote transmission, display, etc.This solid environmental monitoring system combines with Zigbee wireless communicatingprotocol and GPRS wireless transferring technology to set up a WSN environmental monitoringplatform, multi-level network architecture which includes collecting nodes, wireless networkgateway nodes and core server is established. This network not only extends the wirelesscommunicating distance, and greatly enhance the network capacity. An efficient bidirectionalwireless communication between data monitoring nodes and long-distance Monitoring center isfulfilled.This platform is based on TinyOS operating system and programming language NesC asexploring environment, with which, this platform is equipped with good compatibility andportability. The MCU of monitoring nodes are made of MSP430F1611which is16bit single chipwith low power consumption from TI Company, and separate acquisition part andcommunication part with extensible multi-channel input environment parameter transducer,standardized interfaces for environmental monitoring.In this paper, the acquisition and control system were designed. And discussing the fulfillingof multiple hop transmission of self organizing network, CTP routing protocol, designing ofwireless gateway, transferring and real-time display.System as well as single point of control,also can use network, can real-time acquisition in different soil depth in a variety of data such astemperature, humidity, ph value. Contrast and test indicates that solid environmental monitoringsystem can run stably with high measuring precision,and can meet the specific needs of forestsoil environment monitoring.
