Abstract

The invention provides a greenhouse roller shutter control mechanism and method. The mechanism comprises a heat preservation quilt, a roller shutter machine, a supporting structure, a controller and a motor reversing mechanism, wherein the heat preservation quilt covers a greenhouse film of a greenhouse, the roller shutter machine is fixed to a rolling shaft of the heat preservation quilt, the supporting structure is hinged to the ground and fixedly connected with the roller shutter machine, the controller controls the roller shutter machine to operate, and the motor reversing mechanism is connected with the controller and controls the operation direction of the roller shutter machine; the supporting structure comprises an upper connecting rod, a lower connecting rod and an angle encoder, wherein one end of the upper connecting rod is fixed to the roller shutter machine, the lower connecting rod is connected with the upper connecting rod in a hinged mode and hinged to the ground, and the angle encoder is fixed to any hinge connection position and is in signal connection with the controller. According to the technical scheme, the greenhouse roller shutter control mechanism is simple and firm in structure, low in cost, high in automation degree, high in system control precision and great in reliability.

Description

technical field [0001] The invention relates to an agricultural automation application equipment, in particular to a greenhouse roller shutter control mechanism and method. Background technique [0002] In the existing agricultural greenhouses, most of the greenhouse roller blinds are opened and closed manually and manually, without automatic fault detection and alarm functions, running status and position feedback functions, and equipment lacking the above functions Automation and intelligence cannot be realized. The sense of responsibility and mental state of manual operators directly determines the safety and reliability of equipment operation. In actual production, the operation often exceeds the limit, resulting in equipment damage and even personal injury. [0003] In the prior art, there is also an automatic control system to control the rolling shutter of the greenhouse, which moves the rolling machine to the limit position: that is, the control of the uppermost and...
