When people began to control the growth environment of plants, the equipment used was just a simple growth box. Today, with the rapid development of science and technology, artificial climate chambers have been used. The artificial climate chamber is a large-scale experimental equipment that simulates the change of the natural environment. Through the natural environmental parameters of the plant growth, including temperature, humidity, illumination, carbon dioxide content, and nitrogen element content, artificial simulation of the natural environment for plant growth can be achieved. Objectives lay the foundation for formulating control decisions that simulate the natural environment.
The plant growth room, also known as the plant growth artificial climate room, is a professional instrument that artificially regulates the climate of plant growth. The RTOP-D model plant growth room is designed and manufactured by Top Instruments using the national industry standard JB/T6823-93. This system has temperature deviation alarm, limit temperature alarm and protection.
Plant growth room temperature control using FPID fuzzy control, it will affect the temperature of the growth chamber temperature of the environment temperature, the growth chamber set temperature, light intensity and dehumidification status of all factors involved in the temperature of the FPID adjustment, so that the temperature control quality is almost perfect. This technology is at the leading domestic level. The humidity control system of the plant growth climate chamber system also adopts FPID fuzzy control. It not only performs bit PID control of humidity and humidity on the dehumidification and humidification, but also introduces cooling conditions into the humidity control system, and also controls the relationship between humidification and dehumidification. Wet system. It is precisely because of the adoption of the complex and comprehensive FPID fuzzy control technology described above that allows the compressor to operate intermittently and without increasing the dehumidifying equipment, achieving high temperature control and humidity control accuracy. In order to save energy, use intermittent cooling when controlling the temperature and controlling the humidity, and save more than 30% energy than the traditional chiller continuous operation mode.
However, some systems rely on manual point-by-point sampling in the climatic room, and then carry out instrumental measurements or sensory experience judgments. This has the disadvantages of large measurement errors and poor repeatability. To this end, an artificial climate room intelligence test expert system was born. Experts in the experiment studied the distribution of test data such as temperature, humidity, light intensity, carbon dioxide content, and nitrogen element content, and proposed methods for removing the missing error and data mining in the artificial climate room. The problem of rapid and accurate testing of the parameters of the artificial climate room is solved, and the test repeatability and accuracy of the system are effectively improved.
