Example Embodiment

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0018] Such as figure 1 As shown in the figure, a WSN-based environmental quality monitoring system includes sensor nodes, coordinators and upper computers, routers, Internet, and user terminal computers. The sensor node, coordinator and upper computer together form the ZigBee wireless sensor network. The coordinator and the upper computer, namely the ZigBee-IP gateway, are the entrances for the wireless sensor network and the Internet. The sensor nodes are arranged in the monitoring area, such as office buildings, hospitals, conference venues or libraries. The choice of wireless communication between the sensor node and the host computer is because the wireless method is not only convenient for the initial node layout, but also beneficial to change the position of the sensor node in the indoor monitoring at any time. The working principle of the system is: the...

Abstract

The invention discloses a WSN-based environmental quality monitoring system. The system comprises a sensor node, a ZigBee-IP gateway and a user monitoring terminal. The sensor node comprises a master control module, a sensor module and a transparent transmission module. The ZigBee-IP gateway comprises a ZigBee coordinator module and a Mini2440 data processing module. The user monitoring module adopts a bootstarp front end frame constructed user monitoring Web page. Through three sensors, humiture, illumination and dust parameters of an ambient environment are acquired at real time. A user can directly visit a corresponding website via a computer connected to the Internet so as to finish environmental monitoring of a target area. The system provided by the invention has characteristics of monitoring area randomness, expandability, convenient installation, simple maintenance, real-time monitoring and the like.

Description

Technical field [0001] The invention relates to the field of environmental quality monitoring, in particular to an environmental quality monitoring system using WSN. Background technique [0002] The environment is a necessary condition for human survival, and the quality of the environment is directly related to people's health. Especially in some medium and large cities, environmental quality has been included as an indicator of the overall strength of the city. Although as my country attaches great importance to environmental monitoring, the environmental department will send environmental information to all citizens in real time, but there are regional differences in the environment, and often these environmental data cannot well represent the actual local environmental conditions, so we design a set that can measure The indoor or surrounding environment system in the area is particularly important. [0003] Current environmental quality monitoring systems mostly rely on wired...
