Abstract

The invention discloses a comprehensive controller and control method for a sunlight greenhouse electric film rolling machine. The comprehensive controller comprises an automatic control unit, a remote control unit, a manual operation unit and an interlock linkage protection unit. The automatic control unit partially adopts digital tube display, conducts parameter setting in combination with keys and detects an open ventilating opening and a closed ventilating opening according to a temperature and humidity sensor. The remote control unit adopts a coded wireless remote control module. The manual operation unit adopts a double-knife three-gear switch and can achieve film rolling, film releasing and operation stopping. The interlock linkage protection unit guarantees that only one control mode acts for a system at any moment, and other two unit circuits are cut off automatically. By means of the automatic control mode, production and management experience of users is fully considered, and the temperature parameter and the time parameter can be set, so that reasonability and scientificity of rolled film ventilation are improved; the remote control mode and the manual operation mode are added, more choices are provided for the users, and personalized requirements in different seasons and different crop growth stages of the users are met.

Description

technical field [0001] The invention relates to the technical field of agricultural planting machinery, in particular to a comprehensive controller and control method for an electric film rolling machine in a solar greenhouse, and is especially suitable for use by solar greenhouse users who have different requirements for ventilation film rolling control methods. Background technique [0002] Greenhouse ventilation promotes the mass and heat exchange between indoor and outdoor environments. In greenhouse cultivation, ventilation control is a key issue in controlling the cultivation environment, especially has an important impact on the temperature and humidity in the small environment of the greenhouse. Commonly used natural ventilation is to ventilate by opening skylights (vents) or side windows and relying on wind pressure or thermal pressure. Because of its convenient maintenance and no need to consume additional energy, it has become the preferred method of greenhouse env...
