| Our country is a large agricultural country, and agriculture field farming is an integral part of the entire traditional field farming is no longer able to meet the people's production and living needs, with the development of agriculture of things, our traditional agriculture to agriculture began transformation of modern agriculture. The development of the internet of things of agriculture has great values for the realization of automated production agriculture, optimal control, intelligent management. It is of great significance to the realization of agricultural intensification, high yield, high quality, efficient, ecological and security objectives.Traditional farmland environmental monitoring data transmission system has a small range, the high price of hardware, wiring complexity and confusion imperfect data analysis and processing, agricultural research agricultural information Things sensing technology, the transmission of agricultural information technology, agricultural technology, information processing technology demand and technology, it proposed to remotely monitor environmental field design ideas, designed based on ZigBee remote field monitoring system, main contents and conclusions are as follows:(1) Demand for agricultural field management, research and technology of ZigBee sensor technology proposed ZigBee node field data collection, transmission and relay control design ideas, designed based on field data acquisition system of ZigBee. By ZigBee2007 standard Z-Stack protocol research, design and development of application ZigBee wireless sensor network coordinator and each collection of nodes, the program through hardware-based control ZigBee Field environmental information collection system to achieve air temperature and humidity, soil moisture, light and other wireless information collection, display and short-distance transmission, and the ability to complete the end of the relay switching node according to the control instruction. At the same time, low power consumption and reliability of the system starting, ZigBee wireless sensor network module uses Texas Instruments TI's CC2530 module, every half hour on the field of environmental information once the data acquisition, sensor nodes other time in low-power sleep state after experimental testing, the system has a stable reliability.(2) For small traditional field of data transmission range of issues studied microcontroller technology and GPRS mobile communication technology, proposed STC12C5A60S2 SCM control module SIM900 A remote data transmission system is designed SIM900 A SCM control module remote data transmission program, which on the one hand can achieve environmental data receiver coordinator sends to each node collected by GPRS communications technology to remote data transmission to the host computer, on the other hand the control command is sent to the host computer coordinator, to complete the field of intelligent management.(3) Field for the user to obtain information and effective management needs to study the MySQL database, PHP, Apache and TCP / IP protocol technology, is proposed based on the PC field information management system MySQL database, designed and developed based on VC ++ 6.0 PC program, the program is able to receive remote data, the received data is stored in the MySQL database, and the data were analyzed, watering down bit machine issue control instructions. At the same time, the database can accept user access, user-friendly environmental information to obtain their own land.(4) Experimental results show that the proposed design of field-based remote monitoring system ZigBee remote monitoring to achieve the effect of air temperature and humidity, soil moisture, light intensity and other environmental information, and the entire system has high stability and high data transfer effectiveness; when soil moisture exceeds the set threshold, the system can automatically send control commands watering, watering intelligent features; users can get their own fields of environmental information by account number and password to access the database. The system meets the farmland information monitoring process for multi-point, mobility, convenience, remote monitoring and other requirements to address the impact of complex environmental aspects of agricultural information monitoring that while wiring the inconvenience, small transmission range, data storage and analysis and other problems, to meet the monitoring automation, information, intelligence needs of the agricultural environment has important significance for the development of modern agriculture. |
