Example 1
As shown in fig. 1, the monitoring sensor network of the greenhouse group adopted in the invention has a larger scale, a wider coverage area and a high node density, and the network structure presents complex characteristics of distribution, isomerization, multi-level and the like, while the single-greenhouse wireless sensor node has relatively simple networking and small interference signals, the greenhouse group is composed of a plurality of single greenhouses, and the wireless network among the greenhouses needs stronger anti-interference capability.
The invention designs the characteristics of the greenhouse group, which originally inherits the performance optimization of the greenhouse group regulation and control system in the system architecture design, performs dynamic compatible expansibility design on the frame structure reported by the environment sensing node, and performs compatible design on the storage database table and the flow, thereby completing the improvement of the whole system in the performance aspect.
As shown in fig. 2, the present invention is structurally optimized, and structurally divided into a sensing layer, a transmission layer, a support layer and an application layer. Wherein, the operation mode of each monomer greenhouse is as follows: the environment acquisition sensor of the perception layer acquires environment data according to a preset frequency and transmits the environment data to the embedded intelligent gateway according to the preset frequency, and the intelligent gateway performs fusion processing on the environment data acquisition and stores the environment data to a remote database through a 3G/4G/GPRS module. The Web client designs a timer, the timer informs the Web server to inquire the remote database at fixed time intervals, and the Web client is updated after the inquiry results are returned layer by layer. As shown in fig. 3.
Specifically, according to an embodiment of the present invention, in a first aspect, the present invention provides a method for updating multipoint collected data of a greenhouse system, the method including: the method comprises the following steps that a multipoint data acquisition end acquires at least one type of data and reports the at least one type of data to an intelligent gateway; the intelligent gateway discriminates the at least one type of data and uploads the data to a database, and the database automatically updates and stores corresponding data according to the at least one type of data; the client side inquires the database at regular time and updates the client side data according to the database data.

Generally, a wireless sensor network has a large number of nodes, and the wireless sensor network has limited energy and cannot directly communicate with a base station, so an effective routing protocol is needed, while a clustering routing protocol is one of the routing protocols, and the nodes in a neighboring area form a cluster and select a cluster head, the nodes in the cluster transmit data to the cluster head, and the cluster head transmits the data to a next hop or directly to the base station after fusing the data. The byte content length of the at least one type of data satisfies the following condition:
length of byte content of individual node:
length1 ═ 6 × Ni; wherein Ni is the number of sensors of the ith node;
length of byte content of cluster head node:

Preferably, the multipoint data acquisition terminal comprises: the data in different greenhouses are the same, or different data in different greenhouses are different, or different data in the same greenhouse are different.
A large number of acquisition nodes need to be arranged for facility environment monitoring, and because the acquisition nodes can only acquire environment information within the coverage range of the acquisition nodes and cannot consider the spatial correlation of different nodes during data fusion, the acquisition nodes report the time correlation fusion results of the acquisition nodes to a cluster head, and the cluster head performs spatial data correlation fusion according to the node relation. And after the convergent node receives the fusion data points reported by the cluster head, analyzing and reconstructing to recover the original data without distortion.
In order to reduce the data transmission quantity and simultaneously reduce the energy consumption of data acquisition, the data of the nodes in the cluster are compressed by utilizing the spatial correlation of the data so as to reduce the data quantity and the transmission quantity of the acquisition nodes.
The invention designs a data frame design format for compressing and fusing data in a cluster head. As shown in table 1 below
Length of byte content of individual node:
length1 ═ 6 × Ni; wherein Ni is the number of sensors of the ith node;
length of byte content of cluster head node:
Length2＝6*N1+6*N2+…+6*Nm
＝6(N1+N2+.....+Nm)
in the formula, N1, N2, … …, Nm is the number of sensors, and m is the number of nodes.
If the reporting of the multi-source environment information completely depends on the remote server, if the remote server is down due to a certain irresistible reason, the multi-source environment information is necessary to cause loss. The invention adopts the intelligent gateway and the database to directly store data, belongs to desktop application programs, and has enough guarantee for the implementation.
The communication structure is shown in fig. 3: the intelligent gateway stores the environment data into remote data through the communication module according to fixed frequency. The Web client regularly sends a request to the Web server for data in the remote database, the Web server queries the database, reports the query result to the Web client, and the Web client updates the Web page, so that the whole process is completed.
The invention relates to a method for collecting multi-source data of a greenhouse group, wherein the type and the number of sensors of each greenhouse can be dynamically adjusted according to monitoring requirements.
The database design adopts a paradigm structure, the design requirement of a third paradigm commonly used is met, and a four-layer data record table is designed to meet the requirement of multi-source environment information access. According to the design principles of the second and third paradigms of database design, the database table structures are designed as the following tables 2-6.
