Abstract

The invention discloses a PLC-based (programmable logic controller-based) greenhouse auto-control system, comprising a greenhouse frame, a PLC control panel, a first blower, an electromagnetic guide rail, a guide rail mechanism, a first atomizer, a second blower, a third blower, a first electromagnetic valve, a first water pump, a second water pump, a second atomizer, a first temperature regulator, a second temperature regulator and a second electromagnetic valve. The PLC-based greenhouse auto-control system has the advantages that air to be guided into the greenhouse frame is pretreated to temperature and humidity adapted to vegetable growth, so that the influence of heating and humidifying periods of differential air in the greenhouse frame upon vegetables is relieved; temperature and humidity data acquired by multiple first integrated sensing boxes from multiple spots are processed through the PLC control panel, so that interior ambient differences of the greenhouse frame are further decreased, and vegetable yield is increased.

Description

technical field [0001] The invention relates to the technical field of greenhouse automation control systems, in particular to a PLC-based greenhouse automation control system. Background technique [0002] With the continuous progress of the society, the traditional agricultural production mode can no longer meet the needs of the development of modern civilization, and the new type of facility agriculture is sought after by people in the industry. The so-called agricultural equipment is mainly greenhouse facilities, which are not limited by time and space, and can carry out agricultural production in special environments such as plateaus, deep mountains, and deserts. [0003] However, the temperature and humidity inside the greenhouse need to be precisely controlled by the PLC. The existing greenhouses are often only equipped with separate temperature and humidity sensors. The measured data cannot accurately represent the state in the greenhouse, and the data transmitted to...
