Embodiment

[0061] The present invention provides a protective device for the fan and the roller shutter machine in the solar greenhouse, which is applied to the roller shutter system and the ventilation system of the greenhouse, such as figure 1 As shown, the protective devices include:

[0062] The main control unit 6 receives instructions sent by the user terminal through the communication unit, and controls the roller shutter motor 19 or the blower motor 35 to rotate forward, reverse and stop; through the communication unit, the status of the limit unit and the protection unit and other status information are fed back or Push to the client;

[0063] The motor unit, the motor unit includes a rolling shutter motor 19 and a blowing motor 35; the rolling blind motor 19 passes through the first forward contactor and the first reverse contactor, forwardly rolls up and reversely puts down the greenhouse insulation curtain 8; the blowing motor 35. Through the second forward rotation contacto...

Abstract

The invention provides a protecting device and method for exhausting fan and roller blind machine of sunlight greenhouse. The protecting device is applied to a greenhouse roller blind and an exhausting system. The protecting device comprises a master control unit, a communication unit, a motor unit, a limiting unit and a protecting unit, wherein the protecting unit comprises a power-failure limiting module, a roller blind machine monitoring module and an exhausting fan monitoring module; the power-failure limiting module comprises a roller blind machine power-failure limiting module and an exhausting fan power-failure limiting module; the roller blind machine monitoring module and the exhausting fan monitoring module are used for respectively monitoring the rotation direction, number of turns and rotation speed of reels of the roller blind machine and the exhausting fan in real time, meanwhile, the roller blind machine monitoring module is used for monitoring an included angle betweenswing arms of a roller blind system, and the exhausting fan monitoring module is used for monitoring the temperatures and humidity in and outside a sunlight greenhouse in real time. According to the technical scheme provided by the invention, the roller blind and the exhausting system can be protected by virtue of hardware and software, so that the property loss or accident caused when a thermal insulation curtain is moved outside a specified position or an exhausting window is too big or small is avoided.

Description

technical field [0001] The invention relates to the technical field of control of a solar greenhouse blower and roller shutter machine, in particular to a protective device and method for a solar greenhouse blower and a roller shutter. Background technique [0002] In the existing agricultural greenhouses, most of the roller shutter systems in solar greenhouses are only used to protect the shutter machine from stopping at the specified position through limit switches. The limit switches are set in the circuit that controls the forward and reverse of the motor and are used to control the contactor. Whether the coil is de-energized to control whether the motor stops rotating. If the limit switch fails (the limit switch is damaged or the line is loose), the contactor is still in a charged state. If the user rolls or releases the curtain at this time, the motor can still rotate and drive If the thermal insulation curtain continues to go up or down, it will inevitably cause the t...
