Greenhouse roller shutter control system

Abstract

The invention discloses a greenhouse roller shutter control system which comprises a power supply module, an upper computer, a single-chip microcomputer, a relay, an encoder and a DC motor for driving the greenhouse roller shutter. The output end of the power supply module is connected with the relay and the single-chip microcomputer, thereby supplying electric power to the relay and the single-chip microcomputer. The output end of the power supply module is connected with the DC motor through the relay, thereby supplying electric power to the DC motor through the relay. The encoder is mounted on the motor shaft of the DC motor for detecting a real-time operation state of the DC motor. The signal output end of the encoder is connected with the single-chip microcomputer for transmitting the operation state to the single-chip microcomputer. The single-chip microcomputer is connected with the upper computer and the relay for receiving a control signal which is transmitted from the upper computer for controlling the operation state, and controls the operation state of the DC motor through the relay. The greenhouse roller shutter control system has advantages of high stability, low cost, low power consumption, low heating amount, no requirement for complicated programming, high field mounting speed, high effect and high suitability for actual production.

Description

technical field [0001] The invention relates to the field of motor control, in particular to a greenhouse roller blind control system. Background technique [0002] The ventilation operation of the agricultural greenhouse is realized by pulling the canopy film in the forward and reverse directions, and it is usually controlled by manually operating the forward and reverse directions of the DC motor. With the development of the intelligent Internet of Things in the agricultural field, refined automatic control has become a new requirement for greenhouses, which makes the original manual control of the motor into the use of remote communication to drive the operation of the motor. At present, PLC or 51 / 52 single-chip microcomputer is usually used to control the operation of the motor in this field. Although these existing control methods can realize remote control of greenhouse roller blinds, they are large in size, high in cost, high in power consumption, and low in durabili...
