Abstract

A distributed greenhouse temperature and humidity detection system based on a wireless sensor network comprises a host, a plurality of slaves and a mobile terminal like a mobile phone. The slaves are used for measuring temperature and humidity and sending temperature, humidity and the dewing point value to the host through Bluetooth, and the host achieves temperature and humidity long-distance wireless transmission on the basis of the GPRS technology. The system has the advantages that Bluetooth and the GPRS technology are combined, and temperature and humidity distributed measurement and far-distance wireless transmission are achieved; a user can send a command to the host through the mobile terminal and can obtain temperature, humidity and the dewing point value in a greenhouse at any time at any place. The system is simple in structure, high in cost performance, high in practicality and capable of being widely applied to remote suburbs.

Description

A kind of distributed green house temperature-humidity detecting system based on wireless sensor network
Technical field
The present invention relates to a kind of temperature/humiditydetection detection system, be specifically to have employed bluetooth, GPRS technology, a kind of new distribution type temperature/humiditydetection detection system of embedded system composition, belong to green house temperature-humidity detection field.
Background technology
Humiture be agricultural greenhouse most concerned about the physical quantity the most generally detected, the control of humiture in booth is determined to a certain extent to quality and the yield of booth vegetable, even has influence on the life of ordinary people.At present, along with agricultural greenhouse just towards modernization, intelligentized direction develop, the Intelligent Measurement of agricultural greenhouse humiture will be brought into schedule, and traditional artificial Temperature and Humidity method not only inefficiency, and waste time and energy.At present, market also has Temperature and Humidity device based on wireless wifi technology, but this mode to there is also transmission range short, the problem that transmission is unstable, the suburb not covered for wifi and isolated area can not extensively apply.
Summary of the invention
For above-mentioned deficiency, the invention provides a kind of distributed green house temperature-humidity detecting system based on wireless sensor network.
The present invention is achieved by the following technical solutions: a kind of distributed green house temperature-humidity detecting system based on wireless sensor network, it is characterised in that: system is made up of from machine and mobile terminal (such as mobile phone) with several a main frame;Described main frame comprises bluetooth, GPRS module, Embedded Minimum System, power module, and main frame is multiple humiture data measuring point in accepting booth by bluetooth, utilize GPRS technology that humiture data are sent to mobile terminal;Described comprises bluetooth, Embedded Minimum System, Temperature Humidity Sensor, LCD liquid crystal display screen, power module from machine, realizes the measurement of humiture in booth, in real time display from machine and by bluetooth, the data of measurement are sent to main frame.
A kind of distributed green house temperature-humidity detecting system based on wireless sensor network, be further characterized in that big main frame can at set intervals (time can configure according to user's request) or in one day timing send humiture and dew point value to mobile terminal;User also can send command messages by mobile terminal to main frame and obtain humiture and the dew point value of host response;This system also has humiture certain point in prompt facility, i.e. booth that crosses the border and exceedes and roll off the production line in the humiture of user setup, and main frame can send corresponding prompting message from the mobile terminal of trend user.

Embodiment
A kind of distributed green house temperature-humidity detecting system based on wireless sensor network, is to be made up of from machine and mobile terminal with several a main frame, it is characterised in that:
GPRS module is embedded in the main frame (main frame has and only one of which) of green house temperature-humidity detecting system so that main frame and mobile terminal have remote communicating function;GPRS module is made up of SIM900A main control chip, SIM circuit, SP3232E serial port circuit, SMF05C electrostatic discharge protection circuit and peripheral auxiliary circuits;By in commmunication company puts telephone lines into operation the Micro basal groove of the Micro-SIM card insertion SIM circuit with short message service;The data (including humiture and dew point value) detected from machine using Bluetooth technology to will be distributed over each test point in booth are sent to main frame, bluetooth selects HC-08 model, bluetooth 4.0 communications protocol, there is low-power consumption, the advantage that remote, connection speed is fast, transmission range can reach 90 meters, when main frame being placed on the center of booth, accept scope up to 180 meters, exceed well over the full-length (108 meters) of warmhouse booth;Bluetooth is UART interface with the communication of Embedded Minimum System, the most only needs 3 lines, and the Tx line of bluetooth is connected with the Rx line of Embedded Minimum System, and the Rx line of bluetooth is connected with the Tx line of Embedded Minimum System, and bluetooth is with Embedded Minimum System altogether.
Using STM32 Embedded Minimum System, Embedded Minimum System is connected with SIM900A by SP3232E serial ports, it is achieved that embedded system and the serial communication of GPRS module;Meanwhile, the RTC real-time clock of STM32 embedded system is used, it is achieved that in a day of humiture, timing sends humiture and dew point value to mobile terminal;Use DHT11 digital hygro sensor, the GPIO mouth of its single bus interface with embedded system is joined directly together, it is achieved that the data acquisition and procession of embedded system, and calculates corresponding dew point value according to Hygrothermograph;When humiture exceedes and reaches the standard grade or roll off the production line value, detector can send information to mobile terminal;The 192*64 LCDs using KS0108 controller to drive, is connected with embedded system, for warm and humid angle value and the real-time display of dew point value;Power module is made up of 7.2v rechargeable battery set and low-dropout voltage integrated regulator AMS117-3.3V and peripheral auxiliary circuits, has ensured the lasting stability of power supply.
For the ordinary skill in the art, according to claim and the description of the present invention, in the case of principle and the spirit without departing from the present invention, to its change carried out, revise, replace and within modification still falls within protection scope of the present invention.
