Embodiment

[0108] Embodiment: Take the planting of greenhouse facilities as an example to illustrate with specific examples.

[0109] For greenhouses, collection nodes, multi-channel controllers, CO2 sensors and CO2 generators, automatic irrigation and fertilization machines, etc. are often installed. Because sensor or control equipment manufacturers have different definitions of data packet formats during production, and often use different data transmission protocols, resulting in different structures and semantics of collected data, resulting in this greenhouse being a heterogeneous network .

[0110] With the present invention, the traditional wireless sensor network base station is transformed, and communication interfaces are added, such as RS-232, RS-485, USB, RJ45 and other wired communication interfaces, wherein the WSN communication interface uses the communication frequency band of 433MHz to complete the WSN network to the agricultural IoT. Heterogeneous network access, recei...

Abstract

The invention discloses a heterogeneous agricultural Internet of Things interconnection and interworking method. The method comprises steps that (1), heterogeneous network interface communication is realized through utilizing a loosely-coupled communication model taking an improved system base station as a middleware; (2), the XML technology is utilized to realize mutual understanding of data on the basis of heterogeneous network communication; and (3), through the decoupling Kalman filtering algorithm based on the stable gain, the received large-amount redundant data is integrated, and data accuracy is improved. The method is advantaged in that the shortcoming that heterogeneous networks of existing agricultural equipment cannot be integrated with each other in the prior art is overcome,heterogeneous data of the heterogeneous Internet of Things are integrated and filtered, and overall efficiency of the network is improved.

Description

technical field [0001] The present invention relates to the technical field of the agricultural Internet of Things, in particular to a method for interconnection and intercommunication of facility gardening, facility livestock and poultry, facility aquatic products, and field crop IoT heterogeneous networks. Background technique [0002] In the process of agricultural production monitoring, due to the diversity of monitoring objects, each acquisition node and control node has heterogeneity in perception ability and hardware structure; at the same time, due to the definition of data packet format by sensor or control equipment manufacturers They are different, and often use different data transmission protocols, resulting in different structures and syntaxes of the collected data. Therefore, the agricultural Internet of Things is often a heterogeneous network composed of multiple homogeneous or heterogeneous networks in practical applications. The internet. At the same time,...
