now. Although the greenhouse temperature and humidity monitoring system technology has gradually matured, Xiaobian believes that it still has the following problems.

1. The agricultural expert system used in greenhouse monitoring system has its own problems. The development of agricultural expert system technology in China is not very mature. Most of the crop planting knowledge sorted out by agricultural experts belongs to shallow knowledge in this field, and most of them are conditional and regular knowledge. That is to say, most of the knowledge of the system is the rule that the expert door has concluded through multiple experiments under specific conditions and then summarized.In addition, the current agricultural expert system does not integrate how experts learn through learning, The process of obtaining this knowledge through experiments is sorted out. The agricultural expert system developed under such conditions does not have real learning ability. As a result, when our planters apply this system, they can often only deal with what experts have seen and experimented with. We can't adapt to various situations.

2. Restrictions on collecting data. So far, the greenhouse temperature and humidity monitoring system technology has mainly stayed on the monitoring of greenhouse environmental parameters, and has not really considered the physiological growth processes of greenhouse crops, such as vegetation temperature, photosynthesis and transpiration. In fact, the CO2 concentration of the greenhouse should be determined according to the photosynthesis of the vegetation, and the actual photosynthesis data should be used to determine the supply of water and nutrient solution; and the environmental control of the greenhouse should be performed based on the measured values of the vegetation temperature. Moreover, we should constantly compare the measured values with the values of systematic crop growth. Differences between these values may cause adverse results in the process of crop growth and development. This also requires us to master higher greenhouse temperature and humidity monitoring system technology.

3. The agricultural expert system has limitations in real-time control of the greenhouse. Real-time monitoring of greenhouse environmental factors by an agricultural expert system is not as simple as developing a simple agricultural expert system. Real-time monitoring involves the "interface" of the control system. Therefore, when developing the expert control system for greenhouse greenhouse agriculture, we must seriously consider the expression strategies of actual agricultural planting production knowledge. At the same time, more real-time information should be learned from actual agricultural planting, and more agricultural knowledge should be used for real-time control of greenhouse production. Don't limit the agricultural expert system to only expert experiments and technical guidance on environmental factors. Many functions are conducive to the perfect growth of crops. For example, the system is equipped with automatic diagnosis of diseases and insect pests through techniques such as image processing.

If you do the above, then the intelligence of the greenhouse temperature and humidity monitoring system will be greatly improved.
