Embodiment：
Divide compared with the prior art is tested with the system in the present invention applied to Changshu City agricultural greenhouse base
Analysis：Each 400 square metres of greenhouse area, thing grow 50 meters, and 50 prisons are arranged in north and south wide 8 meters in the greenhouse for implementing this system
Survey sensor node, 6 control sensor nodes, warm-air drier of 6 power at 1600-2500 watts, the control of each warm-air drier
One control sensor node of switch connection.
Use 50 temperature sensor nodes of setting, warm wind of 6 power at 1600-2500 watts in prior art greenhouse
Machine.
The indoor preference temperature of temperature is 24 DEG C~26 DEG C, naturally it is also possible to according to crops and the difference of growth district,
Suitable temperature may have certain variation, monitoring system of the invention that can also be set accordingly.
By 6 months contrast experiments, experimental result was：This system can be to cell where each monitoring sensor node
Temperature within the scope of domain carries out effectively monitoring and drives corresponding steam air heater according to monitoring result, and warm indoor temperature control is at 23 DEG C
~27 DEG C, and existing system controls warm indoor temperature at 19 DEG C~31 DEG C.
Comparative analysis conclusion is as follows：
1) temperature sensor node is collected greenhouse temperature house data progress data and melted by existing greenhouse Greenhouse Monitoring system
Data center is transferred to after closing, user is by inquiring monitoring of the data realization of data center to warm indoor temperature, and this is
In system, system is directly accessed internet, and user with the direct point to point link of monitoring sensor node by obtaining warm Indoor Temperature
Degree, therefore there is better real-time；
2) the warm indoor temperature that user monitors in the prior art is the data by fusion, does not embody a certain zonule
Temperature, and in the greenhouse, certain corner regions may have a long way to go with the temperature near warm-air drier, and existing system can not area
Divide this gap, instant certain corner regions temperature are very low, and the temperature that user monitors may be still in set temperature, therefore
Warm-air drier cannot be driven to adjust local temperature in time, and in this system user pass through it is logical with the direct point-to-point of monitoring sensor node
Letter obtains the temperature in small range region where sensor node, so as to effectively monitor the temperature in each corner in greenhouse
Degree to open or relationship warm-air drier in time；
3) in the prior art, since user can only be turned on and off warm-air drier, the degree of automation by live manual type
It is low, therefore warm-air drier cannot be driven to adjust temperature in time, and this system by control sensor node to the unlatching of warm-air drier or
It closes and carries out real-time control, therefore with preferably real-time.
Further, since existing system needs to be turned on and off warm-air drier by live manual type, because also increasing temperature
The cost of room temperature control.
In conclusion the present invention provides the temperature control system based on agriculture sensor network, technique can be applied to
The monitoring and control of industrialized agriculture environment, such as in fields such as gardening, nurseries.Since sensor node has small, price
Cheap, the features such as being easy to arrangement, is easy to maintain, and internet has geographical location covering extensive, it is easy to use, friendly interface,
The features such as low-cost, therefore, this technology, have very high promotional value.
The present invention provides a kind of thinkings of the temperature control system based on agriculture sensor network, implement the technical solution
Method and approach it is very much, the above is only a preferred embodiment of the present invention, it is noted that for the general of the art
For logical technical staff, various improvements and modifications may be made without departing from the principle of the present invention, these improve and
Retouching also should be regarded as protection scope of the present invention.The available prior art of each component part being not known in the present embodiment is subject to reality
It is existing.
