Agricultural wireless sensor network system

Abstract

The invention discloses an agricultural wireless sensor network system. The agricultural wireless sensor network system mainly comprises a sensor network and a cloud storage network, wherein the sensor network mainly comprises terminal nodes, routing nodes and a coordinator, the sensor network protocol forwards data of the terminal nodes between the routing nodes, the terminal nodes are powered by batteries, and the terminal nodes and the routing nodes enter the total power dissipation mode during data transmission and receiving and shift to the sleep mode after completion of the data transmission and receiving; and the cloud storage network comprises a cloud storage server, cloud monitor software and sensor monitor software. By adopting the agricultural wireless sensor network system, the data of the terminal nodes can reach to the objective nodes through different paths, so that power consumption is lowered, and cloud storage networks using clustering technology design have good scalability.

Description

technical field [0001] The invention relates to an agricultural wireless sensor network system, in particular, an agricultural wireless sensor network based on short-range communication and storage and analysis of back-end data. technical background [0002] The standard short-range wireless ZigBee protocol is a wireless standard designed for low cost, low power consumption, and low data traffic. The standard ZigBee protocol specification mainly includes three types of equipment: the coordinator, the end node of routing and cutting functions. figure 1 It is a standard ZigBee topology structure, in which the coordinator is responsible for organizing the network and maintaining the routing table; the router is responsible for communicating with the coordinator of the network, and communicating with other routing and reduction function end nodes of the network; the end node with the reduction function is responsible for communicating with the location The routers of the networ...

Problems solved by technology

In the standard ZigBee protocol specification, because the router and the coordinator cannot sleep, batteries cannot be used for long-term power supply, and wired power supply is required. The implementation site is completely limited by whether the wired power supply can be placed in place, which greatly reduces the flexibility of networking.

[0004] General data storage adopts a data storage server in the local area network, assigns a fixed IP and sets the port number for data communication, the server-side data collector sends the collected data to the fixed port of the designated server, and the server-side uses the service The program continuously scans the data received by the receiving port, so as to realize the server-side storage of terminal data collection, but the general storage method cannot realize the remote storage of distributed data, and the data security is not high. If the amount of stored data is large, it is difficult to realize multiple Load balancing between storage devices or media cannot guarantee automatic migration of data on abnormal devices or media when abnormalities occur in storage devices or media, and cannot achieve non-stop expansion of application services
