Abstract
A soil moisture wireless collecting node with a positioning function is used for collecting soil moisture based on accurate space positions in a crop growing microenvironment and transmitting soil moisture and spatial position coordinates through a ZigBee wireless communication module. The node comprises an ATmega8L controller (1), a soil moisture detecting and collecting module (2), a GPS positioning module (3), the ZigBee wireless communication module (4) and a power module (5). The soil moisture wireless collecting node has a simple structure, a low cost and a certain practical value.
Description
Technical field
The present invention relates to the harvester of the soil moisture based on accurate locus in a kind of crop growth microenvironment, adopt specifically 8 8-digit microcontrollers, TR-5 soil moisture sensor and GPS locating module to be gathered the soil moisture in the crop growth microenvironment of accurate locus under the yardstick of field, and utilize the ZigBee wireless communication module to carry out the wireless transmission of data.
Background technology
At present, modern agriculture strides forward to the precision direction.Precision agriculture is the emerging transsubject complex technology that phase early 1980s International Agriculture field grows up, it is a kind of important modern agriculture form grown up on the basis of a series of new and high technology last words such as modern information technologies, biotechnology, engineering, possesses put agricultural resources to rational use, improves crop yield, the characteristics such as reduce production costs, improve the ecological environment.The field information acquisition technology plays an important role in the implementation process of precision agriculture, low cost, high efficiency intelligent equipment are applied to field information acquisition, obtain the multiple dynamic microenvironment information in real time based on accurate locus such as the humiture that affects crop growth under the yardstick of field, illumination, gas concentration lwevel, can better advance the enforcement of precision agriculture.
When GPS (Global Positioning System) is the satellite survey, the english abbreviation of range-finding navigation/GPS (Navigation Satellite Timing And Ranging/Global Positioning System), be called for short " GPS ".This system is to take satellite as basic radio-navigation positioning system, there is navigation, location and the function regularly of totipotency (land, ocean, aerospace), global, round-the-clock, continuity and real-time, can provide accurate three-dimensional coordinate, speed and the time for all types of user.The development of GPS, synchronously obtaining positional information when obtaining agricultural land information provides one to select easily.GPS equipment can provide spatial positional information accurately, the GPS technology is obtained and combined with agricultural land information, synchronously obtain spatial positional information when obtaining agricultural land information, thereby the in real time dynamically microenvironment information of each locus in the acquisition farmland, for the enforcement of precision agriculture provides Data support.
Along with the development of wireless sensor network technology, and the characteristics of farmland microenvironment information data collection, wireless sensor network technology more and more is applied to the particularly data acquisition of microenvironment information of modern agriculture.A kind of as in wireless sensor network technology of ZigBee technology, have the characteristics such as cost is low, low in energy consumption, network capacity is large, data transmission is reliable, is of wide application.
Summary of the invention
Technical matters to be solved by this invention is, the soil moisture acquisition node based on accurate locus under a kind of with low cost, simple in structure, field yardstick of being easy to promote is provided.
The technical solution adopted in the present invention is: a kind of acquisition node of the soil moisture wireless with positioning function, there is controller, also comprise with controller, be connected for the soil moisture detection acquisition module of soil moisture is provided to controller; With controller, be connected for the GPS locating module of accurate locus is provided; With controller, be connected for carrying out the ZigBee wireless communication module of data wireless transmission.
