Intelligent constant-temperature control device and method for greenhouse

Abstract

The invention discloses an intelligent constant-temperature control device and method for a greenhouse. The device comprises a ventilation module, a refrigeration and heating module, an illumination regulation module, a temperature detection module and a controller, wherein the ventilation module is used for realizing inside and outside ventilation of the greenhouse; the refrigeration and heatingmodule is used for realizing refrigeration or heating in the greenhouse through medium circulation; the illumination regulation module is used for sheltering or guiding light to irradiate the inside of the greenhouse; the temperature detection module is used for detecting inside temperature and outside temperature of the greenhouse; and the controller is used for acquiring temperature informationof the inside temperature and the outside temperature of the greenhouse and controlling the ventilation module, the refrigeration and heating module and the illumination regulation module to work according to the temperature information. Under different conditions, proper temperature regulating methods can be selected, particularly, two rapid temperature regulation means of inside and outside ventilation cooling and sealed illumination heating of the greenhouse are reasonably utilized, the inside temperature regulating rate of the greenhouse is increased, energy consumption is effectively reduced, and the cost is saved; besides, the device and the method also have the advantages of being high in automation degree, convenient to control, high in practicability and the like.

Description

technical field [0001] The invention relates to the technical field of greenhouse regulation technology, in particular to a greenhouse constant temperature intelligent control device and method. Background technique [0002] With the progress and development of modern agriculture, many crops are cultivated and planted in greenhouses. Cultivation and planting in greenhouses require suitable temperature and sunlight, especially for special plants. When the temperature is too high, it will cause Excessive growth nutrients and loss of flower buds will slow down the growth rate of crops when the temperature is too low, so the control of temperature is the most important. [0003] In the prior art, the temperature control of the greenhouse mainly adopts the water curtain wall cooling technology, but the water curtain wall cooling technology is only suitable for lowering the temperature in high temperature seasons, and only plays an auxiliary cooling role, and cannot make the indoo...

Problems solved by technology

[0003] In the prior art, the temperature control of the greenhouse mainly adopts the water curtain wall cooling technology, but the water curtain wall cooling technology is only suitable for lowering the temperature in high temperature seasons, and only plays an auxiliary cooling role, and cannot make the indoor temperature rise and fall freely; some of them use central air conditioning Or the household air conditioner directly cools down. There are many shortcomings in this way, such as high investment cost, high operating cost and energy consumption, slow indoor temperature adjustment speed or uneven temperature adjustment; Coal and boilers are combined or electric boilers and diesel heating machines are used for heating, but this mode is similar to the water curtain wall cooling technology, but it can only be used for heating in winter, and there are environmental protection problems such as high energy consumption and environmental pollution. question
