Hop controller and control method, be particularly well-suited to the heliogreenhouse having different requirement to ventilation wound membrane control mode
User uses.
Background technology
Greenhouse ventilation promotes the mass heat transfer between indoor and outdoor surroundings, and in greenhouse production, Ventilation Control is
Controlling a critical problem of planting environment, the humiture under particularly this to greenhouse subenvironment has important
Impact.Conventional gravity-flow ventilation is by opening skylight (vent) or side window dependence blast or hot pressing function
It is aerated, owing to it is easy to maintenance, is not required to consume the extra energy, it has also become the head of environmental control of greenhouse
Select mode.
Along with the extensive application of the technology such as Internet of Things, modern test and control, use the compositions such as various sensor, alarm
Greenhouse in temperature and humidity monitoring system constantly occur, each measuring point in greenhouse is carried out circling measurment and regulation and control,
Its speed, precision are greatly improved.But these application are mainly for large-scale attached-greenhouse and demonstration type day
Light greenhouse, is affected by factors such as cost, practicality, reliabilities, in the common heliogreenhouse that peasant household manages
Do not form popularization and application.For a long time, heliogreenhouse user still uses the traditional method such as thermometer and drimeter
Gathering temperature and humidity in greenhouse, ventilation is the Main Means of cool-down dehumidification, and these operations are all passed through
Manual operation completes.Owing to thermometer, drimeter precision are relatively low, artificial read untrue, manually leads to
The operation labor intensity such as wind is big, have impact on hothouse production efficiency.Therefore, it is necessary to in heliogreenhouse environment

Through retrieving prior art literature, " heliogreenhouse temperature and humidity intelligent controls system to Chinese utility model patent
System (CN201320429281.3) " disclose a kind of greenhouse based on heliogreenhouse Temperature and Humidity humiture control
System, does not mention other control mode and strategy." warmhouse booth humiture is certainly for Chinese utility model patent
Autocontrol system (CN201220494362.7) " disclose a kind of warmhouse booth temperature/humidity control method, it is achieved
Based on Temperature and Humidity, manually and the shutter of remote control mode, wound membrane machine control, but this utility model does not has
Have realize based on time point control control mode, more not to different control modes that may be present while
Action provides protection, and as automatic detection mode rotates forward, manual mode anyway, will form the positive and negative extremely short of power supply
Connect.Chinese utility model patent " a kind of Intelligent control cabinet for heliogreenhouse (CN201320293268.X) "
Disclose the Intelligent control cabinet of a kind of heliogreenhouse, can realize roller shutter according to soil moisture and aerial temperature and humidity
Machine, wound membrane machine and the control of electromagnetic valve, too much detection and driving means improve the cost of system so that it is
It is not particularly suited for the heliogreenhouse only Ventilation Control required.
These existing public technologies, not taking into full account in the application of common heliogreenhouse cost control, this is quick
Sense factor, can not meet peasant household's multiple diversity operation requirement to the different conditions of production, in reliability design side
Face there is also certain deficiency, therefore have impact on they popularization and application in sunlight greenhouse rolling film ventilating.
