Embodiment 1

[0052] Such as figure 1 As shown, the present embodiment provides a crop irrigation strategy, comprising the following steps:

[0053] Step S1, establishing a generative system knowledge base according to the sample data; and

[0054] Step S2, according to the current growth environment and growth stage data of the crops, determine the current water demand for crop irrigation through fuzzy judgment.

[0055]Wherein, the sample data includes but not limited to crop growth environment data such as crop growth soil type, soil humidity, soil temperature, air relative humidity, air temperature, atmospheric light intensity, wind speed, and sunshine hours.

[0056] Specifically, the method for establishing and generating the system knowledge base according to the sample data in the step S1 includes:

[0057] Step S11, collecting crop growth environment and water demand data information at each growth stage as sample data, and establishing a crop water demand correlation database to...

Embodiment 2

[0092] On the basis of embodiment 1, this embodiment 2 also provides a crop irrigation decision-making system, including: a collection module for collecting data on the current growth environment and growth stage of the crops, and a server connected to the corresponding data collection module of the crops; The server is adapted to regulate the amount of water used for irrigation of crops.

[0093] Specifically, the collection module includes: a soil moisture sensor, a soil temperature sensor, an air humidity sensor, an air temperature sensor, a light intensity sensor and a wind speed sensor, to respectively collect the soil type, soil humidity, soil temperature, relative air humidity, air Temperature, atmospheric light intensity, wind speed, sunshine hours and other crop growth environment data, and the acquired growth environment data is transmitted to the server through the wireless network.

[0094] Each sensor can use a controller as a transmission node to summarize the da...

Abstract

The invention relates to a crop irrigation strategy based on fuzzy judgment and a decision making system. The crop irrigation strategy comprises the following steps: S1, establishing and generating a system knowledge base according to sample data; and S2, determining current water demand for crop irrigation via fuzzy judgment according to current growth environment and growth phase data of crops. The crop irrigation strategy and the crop irrigation decision making system can effectively establish and generate a system knowledge base according to sample data to analyze current growth environment and growth phase data of crops so as to acquire accurate irrigation water quantity; compared with the traditional strategy and system based on soil temperature and humidity, the strategy and the system have the advantages that different soil, growth environments and weather conditions and different growth phases of crops are comprehensively considered, so that the water regime of crops can be reflected more directly; and the growth environment and the growth condition of crops are jointly used as a decision making basis for the water demand of the crops, so that the judgment precision can be improved and the utilization rate of water resources is effectively improved.

Description

technical field [0001] The invention relates to pattern recognition and water-saving irrigation, especially in the crop irrigation decision system based on fuzzy judgment. Background technique [0002] The shortage of water resources is a major problem faced by countries all over the world. The traditional surface irrigation technology is widely used in agricultural irrigation in my country. The irrigation water utilization coefficient is lower than 50%, and the phenomenon of water waste is serious. The implementation of precision irrigation based on the characteristics of crop water demand information is the key to agricultural water saving. efficient way of irrigation. As an industry combining high-tech and agricultural production, precision irrigation precisely controls the timing, water volume, and method of irrigation according to actual conditions such as soil, climate, irrigation facilities, and crop growth, so that crop water demand can reach the best state and water ...
