The system provided by the invention has high data error correction capability and data transmission efficiency, and good application prospects in logistics warehouse management. According to the invention, the system comprises a 51 single-chip microcomputer, a humidity sensor HM1500, a serial interface module, a ZigBee transmitting and receiving module, and a host computer measurement and control system; the humidity sensor HM1500 is arranged in field soil, and soil moisture information is acquired through an AD module of the 51 single-chip microcomputer and displayed through an LED digital tube driven by a display circuit; real-time soil moisture information is transmitted by the 51 single-chip microcomputer through the serial interface module by passing through the ZigBee transmitting and receiving module to a host computer for displaying; when soil moisture content is lower than a set value, an order of starting irrigation is transmitted to a slave computer through the ZigBee wireless transmitting and receiving module, and a water pump is driven by a slave computer single-chip microcomputer system through a drive circuit to irrigate the field, while a buzzer is started for warning and reminding.
Description
Technical field
The invention belongs to the automatic control technology in field irrigation field, specifically a kind of field irrigation automatic measuring and controlling system based on ZigBee.
Background technology
China is large agricultural country, and Water Consumption in Agriculture accounts for more than 80% of social total water consumption; And China's shortage of water resources phenomenon is increasingly severe in recent years, therefore water-saving agriculture will become an important directions of China's modern agricultural development.
At present, although the Water-saving agricultural technology of China's automatic irrigation has had certain development, the extensive phenomenon of flood has been controlled substantially; But great majority are all the irrigation techniques of timing, soil whether all can be irrigated on time by drying, and water utilization rate is also lower, causes the waste of water resource.In addition, the water requirement of crops is also the same not to the utmost to the requirement of moisture at different time, understands soil moisture and reasonably irrigation can have certain help to raising crop yield.
Summary of the invention
The present invention is exactly the problem large for current China agricultural irrigation water amount, water resource utilization efficiency is low, a kind of field irrigation automatic measuring and controlling system based on ZigBee is provided, the present invention has higher error correction capability and data transmission efficiency, in logistic storage management, have good application prospect.
For realizing above-mentioned purpose of the present invention, the present invention adopts following technical scheme.
A kind of field irrigation automatic measuring and controlling system based on ZigBee of the present invention, comprising 51 single-chip microcomputers, humidity sensor HM1500, serial port module, ZigBee transceiver module, host computer TT&C system; Its structural feature is: in field soil, install humidity sensor HM1500, through the A/D module collection of 51 single-chip microcomputers, and by display circuit driving LED numeral method soil moisture information; Real-time soil moisture information is sent to host computer through ZigBee radio receiving transmitting module by serial port module and is shown by 51 single-chip microcomputers; Host computer shows the real time data that slave computer sends on the one hand in real time, on the other hand the soil lower limit that the actual soil water content that records and host computer set is compared: when soil water content is lower than setting value, send to start through ZigBee radio receiving transmitting module and irrigate order to slave computer, slave computer SCM system drives water pump to irrigate to field by drive circuit, starts buzzer simultaneously and carries out alarm.
As a preferred embodiment of the present invention, described 51 single-chip microcomputers adopt the AT89C51 of atmel corp, carry 4K byte FLASH memory, are combined in one single chip by multi-functional 8 bit CPUs and flash memory; The AT89C51 of ATMEL is a kind of efficient microcontroller, for a lot of embedded control system provides the high and inexpensive scheme of a kind of flexibility.
As another kind of preferred version of the present invention, described humidity sensor HM1500 adopts constant voltage to power, built-in amplifying circuit, can export and relative moisture is the volt magnitude voltage signals of proportionate relationship, and fast response time, reproducible, contamination resistance is strong.
As another preferred version of the present invention, described display circuit is made up of LED charactron, and LED charactron is packaged together the device of composition " 8 " font, and lead-in wire is inner to be connected.
The invention has the beneficial effects as follows.
The present invention is based on the field irrigation automatic measuring and controlling system of ZigBee wireless communication technology; Comprise 51 single-chip microcomputers, humidity sensor HM1500, serial port module, ZigBee transceiver module, host computer TT&C system; Measured the moisture of soil by humidity sensor HM1500, gather through slave computer SCM system, and send soil water content data to host computer by ZigBee radio receiving transmitting module; Host computer can Real-Time Monitoring field data, and by comparing with the soil water-physical properties value of setting, irrigate if reach and require, send a command to slave computer through ZigBee, start water pump and irrigate the ZigBee radio communication achieved between lower bit single-chip system and host computer.TT&C system cost of the present invention is low, performance is excellent, for water-saving irrigation system provides reference.
