Embodiment Construction

[0012] An automatic temperature and humidity control device for a greenhouse, which includes an exhaust cooling fan motor and a water spray pipe switch valve, a temperature detection element and a humidity detection element are installed in the greenhouse, the temperature detection element and the humidity detection element are connected to a single-chip controller with wires, and the single-chip The digital quantity output port of the controller is connected with the exhaust cooling fan motor and the water spray pipe switch valve wires.

[0013] The single-chip controller is also connected to the parameter setting unit with wires. The parameter setting unit is a touch screen panel or an input keyboard. Manually set different temperature and humidity comparison values ​​to the single-chip controller according to the plants in different greenhouses, so as to realize automatic temperature and humidity. manage.

[0014] The single-chip microcomputer control room is also integrate...

Abstract

The invention discloses an automatic greenhouse temperature and humidity control device which comprises an exhausting temperature-reducing fan motor and a spray pipe switch valve. A temperature detection element and a humidity detection element are arranged in a greenhouse; the temperature detection element and the humidity detection element are connected with a single-chip microcomputer controller through wires; and a digital quantity output port of the single-chip microcomputer controller is in wire connection with the exhausting temperature-reducing fan motor and the spray pipe switch valve. The automatic greenhouse temperature and humidity control device solves the problems that in the prior art, temperature in the greenhouse is mainly observed manually with a thermometer; when the temperature is too high, an exhaust fan is turned on manually to reduce the temperature, and when humidity is not enough, manual water-spraying humidification is carried out; however, all of the actions above are realized on the basis of manual processing; and through manual processing, the reliability is poor, and human error rate is high and the like.

Description

technical field [0001] The invention belongs to the greenhouse technology, in particular to a greenhouse temperature and humidity automatic control device. Background technique [0002] The application of greenhouse technology is gradually widespread, mainly used in the cultivation of vegetables, water pipes, flowers and plants, etc. The control of temperature and humidity in the greenhouse is very important. Generally, there will be no problems in winter, but in summer due to the hot climate, the greenhouse The temperature in the greenhouse is easy to exceed the standard, and in serious cases, the plants in the greenhouse will be burned to death by high temperature. In the prior art, the temperature in the greenhouse is mainly observed manually with a thermometer. When the temperature is found to be too high, the exhaust fan is manually turned on to cool down. When the humidity is not enough, artificial water spraying is used to humidify, but all of this is based on manual ...
