An all-weather intelligent control method of tuyere motor based on regulating room temperature

Abstract

Based on the all-weather intelligent control method of the tuyere motor that regulates the room temperature, the overall solution is formulated according to the characteristics and functions of the tuyere motor and the tuyere opening and closing device used in the solar greenhouse of different structures, and the corresponding operating rules and indoor temperature prediction models for all weather scenarios are constructed. The relevant thresholds set by the requirements and the real-time data collected are comprehensively analyzed in real time by the control system computer, and the corresponding real-time commands are generated to control the tuyere motor to adjust the opening degree of the tuyere device in the solar greenhouse, so as to achieve precise regulation of the room temperature within the allowable range of natural environment conditions. Mainly, take into account the emergency environmental conditions such as cloudy weather, wind, rain and snow, etc., and deal with them accordingly. It has the characteristics of all-weather unattended, accurate temperature control, saving human resources, preventing accidental losses due to unexpected weather conditions, low cost of cluster control, safe and reliable operation, and strong practicability. It can be widely used in various production industries of solar greenhouses.

Description

technical field [0001] The invention belongs to the technical field of electromechanical intelligent control of smart agricultural solar greenhouses, and relates to an all-weather intelligent control method for a tuyere motor based on regulating and controlling room temperature. Background technique [0002] With the popularization and application of the production mode of solar greenhouse facilities in the field of planting, breeding and agriculture, according to local climate characteristics and industry needs, several types of solar greenhouses, mainly single-arch solar greenhouses, double-arch solar greenhouses and multi-span solar greenhouses, have been formed. Solar greenhouses with different structural features. These solar greenhouse facilities are basically equipped with tuyere devices, so that indoor and outdoor ventilation can be achieved by opening and closing the tuyere, so as to achieve the purpose of adjusting indoor temperature, humidity, carbon dioxide and o...

AI Technical Summary

Problems solved by technology

Manually controlling the tuyere device is completely controlled according to the operating time of the management personnel, which is cumbersome and time-consuming, and it is not easy to achieve timely and effective precise temperature control; most of the existing intelligent technology equipment has the phenomenon of low intelligence and single function. The control method of directly opening all the air outlets or directly closing all the air outlets, especially in the off-season fruit and vegetable production in winter in the northern region, is likely to cause a bad room temperature environment where the indoor temperature drops sharply or rises sharply, or it is easy to suffer from strong winds, rain and snow. Misjudgment occurs, resulting in the phenomenon of frequent opening and closing of the tuyere, and the actual application effect of the technology is not good
