Problems solved by technology

The acquisition of sensing signals adopts the method of wiring. For many occasions, this sensing control system has disadvantages such as difficult wiring, high system cost, high power consumption, difficult and cumbersome maintenance, narrow measurement area, and poor reliability.
[0003] Especially for some control fields, such as fire prevention in forests and grasslands, monitoring of large bridges, etc., it is difficult to collect sensing information by wiring.
In order to meet the requirements for intelligent sensor control in situations such as remote information collection, moving targets, dangerous areas, large-scale monitoring, harsh environments, and no communication network, the traditional sensor system will be difficult to apply, so a set of intelligent assembly must be adopted. A high-performance wireless sensing method with low power consumption and stable channel

Embodiment Construction

[0052] Now according to accompanying drawing, the present invention is described further:

[0053] figure 1 It is the working flow chart of the wireless sensor network intelligent platform. The network nodes collect the monitoring information required by the industrial site through their built-in sensors, and after amplification, filtering, and temperature compensation circuit processing, the signal is input to the The internal processor of the node performs data processing; then the node uses radio frequency wireless and self-organizing network to intelligently select and send the sensing data to the nearest node or base station; through the relay node or base station, it is forwarded to the next relay node or The base stations are relayed in turn; through the above method, the data is sent wirelessly to the wireless gateway connected to the central control computer; the central control computer can perform online on-site programming for the network nodes and base stations of...

Abstract

An embedded wireless sensing network intelligent platform comprises network nodes, a base station, a wireless gateway, and a central control computer, and carries out communication according to an IEEE802.15.4-based Zigbee communication protocol standard. The technique provides an intelligent platform for an embedded wireless sensing network, which can combine required different sensors according to practical control requirement to develop wireless sensing network systems meeting different requirements. The intelligent platform can thoroughly get rid of a wire access manner adopted in conventional sensing control system, and overcome disadvantages such as wiring difficulty, high cost, and maintenance / management difficulty caused by the wire control manner. The platform has high development flexibility, wide operation and application ranges, low cost of system construction and maintenance. Compared with other wireless control manners, the system networking manner has the advantages of combined short-range multihop and grid manner, high intellectualization and reliability, high stability, low power consumption, and long service life.

Description

technical field [0001] The invention relates to an embedded wireless sensor network system, in particular to an embedded wireless sensor network intelligent platform for performing intelligent distributed control and data information fusion on distributed sensor network nodes. Background technique [0002] In modern industry, many industrial control sites need to use a large number of different types of distributed sensing systems for on-site information collection and control. These systems mainly collect on-site information through sensors, and connect the sensor information with signal lines or cables. transmitted to the central control unit for control. The sensing signal is collected by wiring. For many occasions, this sensing control system has disadvantages such as difficult wiring, high system cost, high power consumption, difficult and cumbersome maintenance, narrow measurement area, and poor reliability. [0003] Especially for some control fields, such as fire pr...
