Wireless Sensor Network Technology In The Application Of Water-saving Irrigation

With the development of wireless transmission technology, wireless sensor networks with itscharacteristics of low-power, low-cost, low-rate, short distance, low-latency, high security,agricultural production and pay close attention to solve because of geographical inconveniencebrought about by environmental factors such as wiring, the cost is high.Topics according to the actual needs of the agricultural production, irrigation, combined withthe latest research results in the field of automation technology, single-chip technology, moderncommunications technology, sensor technology, solar technology and wireless communicationtechnology, design a wireless water-saving irrigation control system program. The paperintroduces the process of water-saving irrigation in wireless networking and data transferfunctions.Networking protocol design issues and the needs of the application object, the artificialarrangement node to node distribution of the various monitoring points in the irrigated areas,through the formation of the network, the data is transmitted to the host PC software for dataprocessing control, according to a set threshold, complete unmanned operation environment ofintelligent control of the water-saving irrigation. Software network simulation based the cygwinvirtual environments NS platform, vividly describes the networking process of the network, andthen selected the star network topology. In wireless networking node network solutions, to makethe research and the network networking solutions and network maintenance.The system hardware portion to microcontroller c8051F020as the main processor, wirelesscommunication module selection module NRF905as a wireless transceiver, designed sensornode cells pooled node unit, expansion of the peripheral circuit module functionality.Tested by experiment, the combination of hardware and software platforms workingconditions, to achieve the expected effect of the system design. Analysis of experimental data,and the problems encountered are resolved.
