Abstract

The invention discloses a multi-subarea greenhouse corridor skylight control circuit. The circuit comprises a first intermediate relay KA1, a second intermediate relay KA2, a third intermediate relay KA3, a fourth intermediate relay KA4, a fifth intermediate relay KA5, a sixth intermediate relay KA6, a skylight opening intermediate relay KA7, a skylight shutting intermediate relay KA8, an AC contactor KM1, and an AC contactor KM2. The circuit achieves automatic control of temperature control and air inlet functions of a corridor skylight through parallel and series connections of normally-open and normally-closed contacts of the intermediate relays and the AC contactors. An existing greenhouse controller program does not need to be modified, only a few electronic components are added, and thus the circuit is simple in structure.

Description

technical field [0001] The invention relates to a control circuit for a skylight in a corridor of a multi-zone greenhouse, which can realize the temperature control of the skylight in the corridor and the automatic control of the air inlet function. Background technique [0002] In order to make the layout of the multi-zone greenhouse compact, more corridors are designed to connect each zone. Due to the functional needs of the greenhouse for energy saving in winter and daily shelter from wind and rain, the corridors are required to be closed structures. This also requires that the skylights configured in the corridors should not only be used to adjust and control the temperature of the corridors, but also be used as air inlets for the wet curtain fans in each zone of the greenhouse. The existing greenhouse automatic controller generally includes a sensor input module, an automatic controller calculation module, and a relay signal output module. In terms of software design, ...
