| In order to completely change poor farmland irrigation in the traditional agricultural production and save farmers irrigation time queuing,with the development of “the Internet plus agriculture ",this paper designs a smart phone reservation system of farmland irrigation based on “the internet plus”.The system uses the Internet technology and real-time collects of farmland moisture information through wireless sensor network.It uses the GPRS module to send the collected information to the remote monitoring center server and realizes the remote monitoring and intelligent management process of farmland irrigation.At the same time,the system server can exchange information and intelligent mobile phone using custom communication protocol.Through the mobile phone,the farmers see irrigation of farmland information and make an farmland irrigation appointment.Therefore,the open reservation irrigation system without the time and geographical restrictions,effectively overcomes the disadvantages of traditional farmland irrigation line.The experimental results show that the irrigation reservation system using "Internet plus" technology is convenient,flexible and effective.And it has the practical significance to promote the furtherdevelopment of modern agriculture.The main contents include:(1)This paper analyzes the present situation of irrigation at home and abroad,and briefly expounds the related technologies such as Zigbee,Android,GPRS and so on;(2)According to the actual situation of irrigation appointment,the paper determines the system function requirements and system design principles.And it puts forward the overall design scheme of irrigation reservation system based on Android intelligent mobile phone,including irrigation area,remote monitoring center and mobile phone Android client of three parts,including farmland irrigation area,remote monitoring center and Android phone client.Remote monitoring center,as a farmland irrigation area and the Android phone client connection hub,realizes the effective interaction of information;(3)The hardware design of the system includes three parts: terminal sensor node,wireless gateway node and solar power supply circuit.The terminal sensor node completes the farmland information collection,and the wireless gateway node is responsible for transmitting the collected information and controlling the irrigation order;(4)The paper designs and implements of system software,including CC2531 node,wireless gateway,remote monitoring center and Android mobile phone client.The CC2531 node and wireless gateway are responsible for establishing a network connection for farmland irrigation and remote monitoringcenters.Remote monitoring software is responsible for finishing and storage of farmland to collect information,control irrigation.It is easy to Android client access;Finally,the whole system is tested and the overall performance of the system is evaluated.Zigbee network test is successful.The acquisition of farmland information achieves remote transmission,and Android client complete the information interaction exchange.The test results show that the irrigation reservation system based on “the internet plus” achieves the design goal.It is convenient,flexible,fast and has friendly operation interface.And it has wide application prospect and popularization value in modern agricultural production. |
