Content of the invention
In view of this, it is contemplated that proposing a kind of photoswitch of greenhouse high temperature self-starting and using method, to solve
In prior art not enough, it is to avoid the uncertainty of manual control, it is achieved that the automatic regulation of greenhouse cooling system.
For above-mentioned purpose is reached, the technical scheme is that and be achieved in that：
A kind of photoswitch of greenhouse high temperature self-starting, including light source, transparent vessel and photoelectric sensor, described
Bright container is Wei Yu light source and photoelectric sensor between, and the transparent vessel is built with the hydrated salt of low-temperature melting point.
Preferably, the hydrated salt of the low-temperature melting point for fusing point be located at 25-45 DEG C between be hydrated salt.
Preferably, the hydrated salt of the low-temperature melting point is calcium chloride, sodium carbonate, sodium sulfate and sodium dihydrogen phosphate containing not
The salt of syncrystallization water and its mixture；.
Preferably, the transparent vessel is glass container or quartz container.
Preferably, the light source is light of the wavelength between 380-1100 nanometer.
Preferably, the light source is visible or infrared light.
Preferably, the photoelectric sensor be receive illumination after can produce action potential optoelectronic induction material and its
Signal amplifying apparatus.
The present invention provides a kind of method using photoswitch as above, is transferred heat to by greenhouse high temperature
The hydrated salt of the low-temperature melting point in bright container, after room temperature is higher than the fusing point of salt, the hydrated salt of low-temperature melting point absorbs heat melts
For liquid, the light for enabling light source to send is perceived by photoelectric sensor by transparent vessel and solution and produces switching signal, and then
The cooling system for starting greenhouse realizes the Automated condtrol of greenhouse cooling system.
With respect to prior art, a kind of photoswitch of greenhouse high temperature self-starting of the present invention and using method, tool
There is following advantage：Present invention, avoiding the uncertainty of manual control, it is achieved that the automatic regulation of greenhouse cooling system.This
Bright simple structure, on the premise of reduces cost, also improves the accuracy of greenhouse cooling system regulation, it is ensured that used as not by height
Temperature injury.
Description of the drawings
The accompanying drawing for constituting the part of the present invention is used for providing a further understanding of the present invention, the schematic reality of the present invention
Apply example and its illustrate, for the present invention is explained, not constituting inappropriate limitation of the present invention.In the accompanying drawings：
Fig. 1 is the simple structure schematic diagram of the photoswitch of the greenhouse high temperature self-starting described in the embodiment of the present invention.
Description of reference numerals：
