Zigbee wireless sensor network based system and method for monitoring microenvironment of cabinet

Abstract

The invention discloses a zigbee wireless sensor network based system and method for monitoring the microenvironment of a cabinet. The system comprises power distribution units for the cabinet with data nodes, convergent nodes and a wireless sensor network management platform. The power distribution units are used for adopting wireless sensors arranged in the power distribution units to collect such information as supply voltage, supply current, temperature and humidity in the microenvironment of the cabinet while distributing power for the cabinet, and are used for transmitting the collected data to the convergent nodes via wireless signals. The convergent nodes are connected with a plurality of power distribution units in a wireless manner, are used for taking charge of organizing, establishing, maintaining and controlling the wireless sensor networks formed by the power distribution units and are used for receiving the collected data. The convergent nodes are also connected with the wireless sensor network management platform via the Ethernet and transmit the received collected data to the wireless sensor network management platform via the Ethernet. The wireless sensor network management platform is used for receiving the collected data transmitted by the convergent nodes, analyzing the collected data and managing the wireless sensor network.

Description

technical field [0001] The invention relates to the technical field of wireless transmission, in particular to a cabinet microenvironment monitoring system and method based on a Zigbee wireless sensor network. Background technique [0002] At present, wireless transmission technology is rapidly entering many application fields. Compared with wired equipment, it has the advantages of low cost, easy portability, and no need for wiring. In the field of short-distance wireless communication where there are many standards, the rapid development of zigbee technology can be said to be unexpected. Zigbee is a wireless technical standard based on IEEE802.15.4 wireless standard related to networking, security and application software. Zigbee technology has the advantages of low energy consumption, low cost, low complexity, large network capacity, high security, flexible working frequency band, and short delay. Under the impetus of Zigbee Alliance and IEEE802.15.4, Zigbee technology ...

AI Technical Summary

Problems solved by technology

[0005] 1. In large and medium-sized computer systems, IT equipment is rack-based, with many types of business, large business volume, high-density IT equipment, and large heat dissipation, but the micro-environment in the cabinet is not included in centralized monitoring;

[0006] 2. The computer monitoring system is mainly aimed at the macro-environment of the computer system, and cannot effectively take into account the micro-environment of the cabinet;

[0007] 3. The computer monitoring system and computer system construction are carried out at the same time, requiring construction and wiring, complex network and high cost;

[0008] 4. The computer monitoring system is based on "wired" technology, once the construction is successful, the expansion is not flexible;
