Abstract

Disclosed in the invention is an automatic control circuit of a greenhouse. The automatic control circuit comprises a control chip connected with a clock circuit, a nixie tube display circuit, a nixie tube drive circuit, a button input circuit, a button control circuit, and a relay control circuit respectively. The nixie tube display circuit employs a common-anode quaternity 12-pin nixie tube. The nixie tube drive circuit is formed by a plurality of resistors and a triode. The button input circuit includes a function button, a parameter button, an increasing button, a reduction button, and a reset button. The button control circuit is formed by a multi-stage amplification circuit. According to the invention, the provided automatic control circuit has advantages of reasonable structural design, simple control principle, simple and easily-controlled control process, convenient operation, and low manufacturing cost; matching of all control lamps, temperature control and humidity control inside a greenhouse is realized; automatic control is realized; and the manual operation cost is lowered.

Description

technical field [0001] The invention relates to an automatic control circuit, in particular to an automatic control circuit applied in a greenhouse. Background technique [0002] Facility agriculture is one of the most dynamic emerging industries at present, and greenhouses are typical equipment for facility agriculture. A greenhouse is a place that can change the plant growth environment, create the best conditions for plant growth, and avoid the influence of seasonal changes and harsh weather outside. It has the advantages of rational use of agricultural resources, protection of the ecological environment, and increase of agricultural production. Greenhouse control technology is a cutting-edge research field in the world. Its key technology is to collect and effectively control environmental factors such as temperature, humidity, and light. The ultimate goal of this technology is to improve control and operation accuracy. [0003] With the continuous improvement of the sc...
