Temperature and humidity automatic adjustment control system for greenhouse

Abstract

The invention relates to a temperature and humidity automatic adjustment control system for a greenhouse, and belongs to the technical field of agricultural plantation. The system comprises a vegetable room, and the upper part of the vegetable room is provided with 2-3 temperature and humidity sensors. The central part of the upper part of the vegetable room is provided with a greenhouse humidifier, and the interior of the vegetable room is provided with an air conditioner. The temperature and humidity sensor, the greenhouse humidifier and the air conditioner are connected with a control device. The top of the vegetable room is provided with an arched roof, and the arched roof is supported by a support. The bottom of the arched roof is provided with a stainless steel plate material, and the stainless steel plate material is provided with a pipe groove. The interior of the pipe groove is provided with a floor heating pipe, and the upper end of the floor heating pipe is provided with a polystyrene board. The system is provided with the temperature and humidity sensor, the greenhouse humidifier, the air conditioner and the control device, so the system can automatically detect the temperature and humidity through the temperature and humidity sensor and transmit the temperature and humidity to the control device, control the on / off of the greenhouse humidifier and the air conditioner through the control device, and further control the internal temperature and humidity of the greenhouse. Therefore, the system is high in automation degree.

Description

technical field [0001] The invention relates to a vegetable greenhouse, in particular to a temperature and humidity automatic adjustment control system for the greenhouse, which belongs to the technical field of agricultural planting. Background technique [0002] The vegetable greenhouse is a frame-covered structure with excellent thermal insulation performance. It appears that people can eat off-season vegetables. Generally, a vegetable greenhouse uses a bamboo structure or a steel structure support frame, covered with one or more layers of thermal insulation plastic film, thus forming a greenhouse space. The outer film can well prevent the loss of carbon dioxide produced by the growth of vegetables inside, so that the shed has a good heat preservation effect. [0003] At present, with the continuous improvement of people's living conditions, people's requirements for vegetable types are getting higher and higher. Therefore, the requirements for heat preservation and safe...

AI Technical Summary

Problems solved by technology

At present, the ceiling of the vegetable room is mostly flat, and the temperature of the vegetable room is lower than the room temperature, which will easily cause temperature difference to cause condensation on the ceiling, and the condensed water will drip on the vegetables, which will easily affect the quality of the vegetables.

At the same time, the temperature of the greenhouse is now artificially sensed, and often due to wrong information, the temperature is not suitable, resulting in reduced vegetable production and poor taste, directly affecting economic benefits
