All-weather intelligent control method for tuyere motor based on regulation and control of room temperature

Abstract

The invention discloses an all-weather intelligent control method for a tuyere motor based on regulation and control of room temperature. An overall solution is formulated according to the characteristics and functions of the tuyere motor and the tuyere opening and closing device adopted by sunlight greenhouses of different structures, and all-weather operation rules, indoor temperature prediction models and other models corresponding to all-weather scenes are constructed; according to relevant threshold values set according to actual production requirements and the collected real-time data, real-time comprehensive analysis is conducted through a control system computer, a corresponding real-time instruction is generated to control an air port motor to adjust the opening degree of the solar greenhouse air port device, and accurate room temperature regulation and control within the permissible range of natural environment conditions are mainly achieved; and corresponding treatment is carried out in emergency environment states such as timely ventilation in cloudy days, strong wind, rain, snow and the like. The method has the characteristics of all-weather unattended operation, accurate temperature control, manpower resource saving, prevention of accidental loss caused by sudden weather conditions, low cluster control cost, safe and reliable operation, high practicability and the like, and can be widely applied to various production industries of sunlight greenhouses.

Description

technical field [0001] The invention belongs to the technical field of electromechanical intelligent control in a smart agricultural solar greenhouse, and relates to an all-weather intelligent control method for tuyere motors based on adjusting 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 and breeding agriculture, several types of solar greenhouses, including single-arch solar greenhouses, double-arch solar greenhouses and multi-span solar greenhouses, have been formed based on local climate characteristics and industry needs. Solar greenhouses with different structural features. These solar greenhouse facilities are basically equipped with tuyere devices, so that indoor and outdoor ventilation can be realized by opening and closing the tuyere, so as to achieve the purpose of adjusting indoor temperature, humidity, carbon dioxide and other...

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
