Problems solved by technology

Existing methods based on statistical fusion, such as Bayesian fusion, must require data to conform to a normal distribution [7] , BP artificial neural network takes a long time to train and is prone to local minimum without convergence [8] , will lead to inaccurate decision data, while other methods run for a long time and cannot meet real-time requirements

Embodiment Construction

[0053] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0054] Such as figure 1 As shown, it is a schematic structural diagram of the multi-data-based crop water demand detection system of the present invention, including:

[0055] The data detection unit 1 is used to detect and collect crop growth information (crop stem flow, leaf temperature, crop moisture content and soil moisture content) in real time. It includes: several terminal collectors 11, a router 12 and at least one coordinator 13, the coordinator 13 is connected to the wireless transmission unit 2, and the terminal collector 11 is used to transmit the collected crop growth information to the coordinator 13 through the router 11. Among them, such as figure 2 As...

Abstract

The invention relates to a multi-data based crop water demand detection system, comprising a data detection unit, a wireless transmission unit, a data fusion processing unit and a decision information publishing unit, wherein the data detection unit is used for detecting and acquiring crop growth information in real time, the wireless transmission unit is used for transmitting the growth information to the data fusion processing unit, the data fusion processing unit is used for fusing and processing different data in the growth information and obtaining decision information on whether the crop demands water or not, and the decision information unit is used for publishing the decision information on whether the crop demands water or not. The invention further discloses a multi-data based crop water demand detection method. The invention can carry out rapid and dynamic monitoring on the crop and make an accurate judgment on the water demand state of the crop.

Description

technical field [0001] The invention relates to the technical field of agricultural information, in particular to a crop water demand detection system and detection method based on multiple data. Background technique [0002] Wireless sensor network (Wireless Sensor Network, WSN) can real-time monitor, perceive and collect the information of the environment or monitoring objects in the network distribution area through various sensors, and receive and send information in a wireless way, in the network mode of self-organizing multi-hop routing transmitted to the user terminal, and also has simple data processing and control functions [1] . Wireless sensor networks provide new ideas and powerful means for information collection and processing in various fields of agriculture. Due to the large area covered by agricultural production, a monitoring network needs to be composed of a large number of sensor nodes to collect soil moisture, nitrogen concentration, pH value, and rainf...
