The Research And Design Of The Tree Growth Monitoring System Based On Wireless Sensor Networks

WSN (Wireless Sensor Networks) is an application-based network, through varioustypes of integrated micro-sensors to work together to complete the information on a variety ofmonitoring object real-time monitoring, sensing and acquisition, by wireless meansThisinformation is transmitted to the user. It was broad range of applications for environmentalmonitoring and other fields by advantage of the technology with real-time, low powerconsumption and other aspects. The dissertation for the forestry environmental monitoringdata collected instability, real-time, equipment maintenance, the practical problems ofinconvenience, designed and implemented a set of unmanned, low-power, easy-to trees basedon wireless sensor networks growth monitoring system.Dissertation use ZigBee technology to achieve the monitoring of regional wireless sensornetwork communication, using GPRS technology to achieve communication between themonitoring of regional and remote monitoring center. Low-power processor and a dedicatedsensor to the terminal nodes of the sensor network, collection, send the information of themonitored object; the coordination of the sensor network using ARM9embedded processor tocomplete the summary of the data processing and remote send; systems controlled bysoftware real-time acquisition of high-precision data, the remote to send the backup data isstored.Dissertation according to the actual needs of the ARM9development board and ZigBeedevelopment board to build wireless sensor networks, sensor networks, embedded systems tocoordinate hardware, each node hardware circuit to do a preliminary design, thetransplantation of the operating system and the development of the underlying driver tocomplete the ZigBee protocol architecture networking and communication experiment. Dataacquisition, communications and networking test procedures to achieve the basic functions ofthe beginning of the monitoring system design.
