Integrated controller and control method for solar greenhouse electric film rolling machine

Abstract

The invention discloses a comprehensive controller and a control method for an electric film rolling machine in a solar greenhouse, comprising an automatic control unit, a remote control unit, a manual operation unit and an interlocking linkage protection unit. The automatic control unit part adopts the digital tube display and combines the buttons to set the parameters, and opens and closes the vents according to the temperature and humidity sensor detection. The remote control unit adopts a coded wireless remote control module. The manual operation unit adopts a double-pole three-speed switch, which can realize film roll, film release and stop operation. The interlock linkage protection unit ensures that only one control mode of the system works at any time, and automatically cuts off the circuits of the other two units. The automatic control mode of the present invention fully considers the user's production management experience, and the temperature and time parameters can be set to improve the rationality and scientificity of the roll film ventilation. The addition of remote control and manual methods provides users with more choices and meets the individual needs of users in different seasons and different crop growth stages.

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...
