Plant growth characteristics based adaptive tracking and changing system of greenhouse colored films

Abstract

The invention relates to a plant growth characteristics based adaptive tracking and changing system of greenhouse colored films. The adaptive tracking and changing system comprises a sensing module, a deciding module and an executing module. The sensing module comprises a light sensor unit, a temperature sensor unit, a humidity sensor unit and a plant growth status sensor unit which are used for detecting a light environment, temperature and humidity and plant growth status in a greenhouse in real time and transmitting detected results in real time to the deciding module for judgment; the deciding module acquires status information of a current plant growth stage according to the detected results in real time, selects corresponding colored films based on light conditions and temperature and humidity conditions required by the current plants in the current growth stage, and inputs the information into the executing mechanism. The colored films at the top of the greenhouse can be detected and changed automatically to regulate intensity and frequency range of sunlight entering the greenhouse, the best lighting conditions are provided for the whole process of plant growth, and the purposes of increasing both production and income can be achieved.

Description

technical field [0001] The invention relates to the field of facility agricultural production, in particular to an adaptive tracking and replacement system for colored films in greenhouses based on plant growth characteristics. Background technique [0002] With the development of our country's economy, the problem of slow increase in farmers' income has gradually emerged. The key to solving this problem is to vigorously develop agricultural science and technology and gradually move towards agricultural modernization. my country has a vast territory and belongs to the continental monsoon climate. Compared with other countries and regions at the same latitude, it has the characteristics of large annual temperature difference and harsh extreme weather conditions. Therefore, greenhouse technology is one of the key points of agricultural development in my country, and this technology has been widely promoted in the northern region. [0003] The greenhouse, also known as the gre...

Problems solved by technology

[0005] At present, the patent applications for greenhouse films, such as application number 201310089024.4, etc., are all aimed at the manufacturing process of film materials, and there is no automatic detection and replacement system for greenhouse films for different planting crops and different growth stages of crops. Traditional and common The greenhouse uses a consistent transparent film throughout the growth of the plants, which may facilitate some stages of plant growth and hinder others
