The Mathematic Model and Control of Radix Acanthopanacis Semticosis Growth Which Imitates Natural Environment
The design in this paper is a kind of greenhouse control system which imitates temperature and humidity on the basis of digital temperature sensor DS18B20. The system has the following characteristics: the temperature control system is the system which imitates natural environment, the system could get the optimal values about temperature and humidity which fit Radix Acanthopanacis Semticosis growth in accordance with its characteristics which growing in natural environment In this paper, we first analyzed the state of environment which fits Radix Acanthopanacis Semticosis growth. Then we have found its optimal growth rhythm. We also have built its corresponding mathematic model. So, we could depend on computer to control Radix Acanthopanacis Semticosis growing in accordance with the mathematic model. The intelligent control system of temperature has easy peripheral circuits, and these circuits have such advantages as high precision and reliability, remote measuring and control. By imitating Radix Acanthopanacis Semticosis growth in greenhouse and analyzing the composition of soil, we find that there is no difference between natural Radix Acanthopanacis Semticosi and its cultivated form. They have the same pesticide effect.
