Embodiment Construction

[0044] As mentioned in the background technology section, the current greenhouse temperature control method not only wastes resources, but also has a certain hysteresis in temperature control.

[0045] Based on the above research, the embodiment of the present invention provides a greenhouse temperature control method and system, which adjusts the indoor temperature in advance within a preset time period by predicting the temperature value at a future time point, so that when the future time is reached At this point, the indoor temperature can be within the temperature threshold range suitable for plant growth. Therefore, compared with the greenhouse where the temperature is adjusted when the indoor temperature is not suitable for plant growth, the indoor temperature of the greenhouse can always be within the temperature threshold range suitable for plant growth, which is more conducive to the growth of plants.

[0046] In order to make the above objects, features and advantag...

Abstract

The invention discloses a greenhouse temperature control method. The greenhouse temperature control method comprises the following steps: acquiring an outdoor prediction temperature value at a future time point; predicting an indoor prediction temperature value according to the outdoor prediction temperature value; judging whether the indoor prediction temperature value is accordant with a temperature threshold suitable for the growth of plants; and if not, regulating an indoor temperature in a preset time period before the future time point according to the indoor prediction temperature value. The invention further discloses a greenhouse temperature control device. The greenhouse temperature control device comprises a prediction temperature value acquiring device, an indoor temperature sensor, temperature regulating equipment and a controller, wherein the controller comprises a pre-control module, the pre-control module is used for judging whether the indoor prediction temperature value is accordant with a temperature threshold suitable for the growth of plants at the future time point, and if no, regulating the indoor temperature of a greenhouse by virtue of the temperature regulating equipment in a preset time period before the future time point according to the indoor prediction temperature value. Therefore, the problem of temperature control hysteresis of the greenhouse can be avoided, the energy is saved, and the growth of the plants is benefited.

Description

technical field [0001] The invention relates to the field of plant planting, in particular to a greenhouse temperature control method and a greenhouse temperature control system. Background technique [0002] Greenhouses provide an unnatural growth environment to ensure that plants grow at a suitable temperature. However, the existing greenhouses mainly detect the temperature in the greenhouse in real time. If the detected temperature does not meet the temperature suitable for plant growth, it will be adjusted by the temperature adjustment equipment. Therefore, the way to adjust the temperature has a certain hysteresis, and A large temperature adjustment is required, which not only consumes a lot of energy, but is also not conducive to the growth of plants. [0003] Therefore, how to solve the problems of hysteresis and high energy consumption in greenhouse temperature control is a technical problem urgently needed by those skilled in the art.
