Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] Such as figure 1 As shown, the intelligent greenhouse rolling shutter control system based on multi-sensor information fusion technology consists of a data acquisition system, microcontroller, actuator system, and human-computer interaction system to form a complete automatic control system, which realizes the automation and control of greenhouse management. Intelligent. The data acquisition system includes a sensor system and a limit switch, and the sensor system can be subdivided into temperature sensors, humidity sensors, and light sensors. As a preference, the microcontroller selects STC89C52 single-chip microcomputer, which has stable and reliable performance and low cost. As a preference, the actuator system uses a three-phase motor forward and reverse solid state relay. The human-computer interaction system is divided...

Abstract

The invention discloses an intelligent greenhouse roller curtain control system based on a multi-sensor information fusion technology. In the system, a single chip microcomputer detects roller curtain machine position feedback information fed back by a temperature sensor, a light sensor, a moisture sensor, an upper limiting switch and a lower limiting switch, accordingly, the inner-outer environment state of a solar greenhouse is judged, then the single chip microcomputer sends control information to a solid-state relay which controls automatic rolling and falling action of a greenhouse straw curtain, and meanwhile real-time temperature of the greenhouse and relative humidity of atmosphere are displayed through a Nixie tube. According to the intelligent greenhouse roller curtain control system, automatic curtain rolling and falling of the roller curtain machine are achieved under the situations of day-night alternating, bad weather and temperature shock, the labor intensity of greenhouse farmers is greatly lowered, production efficiency is improved, and production cost is lowered.

Description

technical field [0001] The invention belongs to the field of agricultural engineering applications, and relates to a greenhouse roller blind control system, in particular to an intelligent greenhouse roller blind control system based on multi-sensor information fusion technology. Background technique [0002] In recent years, solar greenhouses have developed rapidly in most of the rural areas in northern China. On the basis of ensuring the whole society's vegetable blue project, farmers' income has been significantly improved. At present, most domestic greenhouses have achieved mechanization or semi-mechanization, that is, through mechanical switches Manually control the rolling and opening of the rolling machine. [0003] Manually controlling the shutter machine not only requires a lot of labor but also has low production efficiency. Although there are already advanced smart greenhouses, this kind of greenhouse has too much initial investment and high production costs, and...
