Lifting controller of curtain coiling machine of greenhouse

Abstract

The invention relates to a lifting controller of a curtain coiling machine of a greenhouse, which comprises a personal computer (PC) control circuit, a temperature sensor, a contactor and a motor of a curtain coiling machine, wherein the PC control circuit is respectively connected with the contactor and the temperature sensor, and the contactor is connected with the motor of the curtain coiling machine; and the PC control circuit comprises a control chip and also comprises a display and an operating button which are connected with the control chip. The lifting controller of the curtain coiling machine of the greenhouse is safe and reliable and conforms to the special agricultural requirement of protected agriculture. By the double-information control of time-sequence logic and temperature, the requirement of growth of crops is ensured. By setting through intellectualized remote manual operation, the lifting height of a coiling curtain and the light irradiation time and temperature in the greenhouse can be accurately controlled, and the aim of instant management without manpower is realized.

Description

technical field [0001] The invention relates to an automatic control device for agricultural machinery, in particular to an automatic and intelligent lifting controller for a roller shutter machine in a greenhouse. Background technique [0002] At present, the application rate of roller shutter machines in my country's facility agriculture has reached more than 60%, and it continues to increase. The use of roller blinds is mainly controlled by manual guide switches: roll up in the morning and fall down at night; a small amount of useful remote control guides. But none of this is outdated in the backward ways of manual oversight. Now we have found the publicity about the intelligent controller of the greenhouse roller shutter machine, but its design principle is industrial engineering control, that is, sequence control or contactor limit control, which is far from the requirements of agronomy, and has not yet been applied in general production. . Moreover, in actual produc...

But these are not out of the backward way of human supervision

Now we have found the publicity about the intelligent controller of the greenhouse roller shutter machine, but its design principle is industrial engineering control, that is, sequence control or contactor limit control, which is far from the requirements of agronomy, and has not yet been applied in general production.

Moreover, in actual production, the existing intelligent controller often causes accidents in which the shutter machine exceeds the shed ridge, causing direct economic losses to production. Many farmers often stop the shutter machine in advance to prevent this accident, resulting in The light entering rate of the greenhouse is low, the temperature rises slowly, and the photosynthesis is insufficient; when the curtain is closed based on time, it is easy to cause the temperature of the greenhouse at night to be unreasonable, so that the crops cannot breathe normally, the development of the root system is hindered, and the cell division is deformed. The improvement of yield and quality has brought endless troubles to greenhouse farmers
