Wireless sensor node for remotely and automatically sampling and measuring air quality

Abstract

The invention discloses a wireless sensor node for remotely and automatically sampling and measuring the air quality. The wireless sensor node comprises a sensor module, a CPU processing module, a short-distance wireless communication module used for automatically searching adjacent wireless sensor nodes and bidirectionally communicating with the searched nodes, a data storage module for synchronously storing data acquired by the sensor module and the operation parameters relative to the CPU processing module, an RF (Radio Frequency) transceiver used for synchronously uploading the data acquired by the sensor module, a self-locating module, a timing module and a power supply module, wherein a data correction module for automatically verifying the data acquired by the sensor module is integrated in the CPU processing module. The wireless sensor node provided by the invention has the advantages of convenience in mounting and maintenance, low power consumption, stability and reliability in information transmission, and strong self-locating ability and communication function, and can overcome the defects of inaccurate information acquisition and transmission, discontinuous data transmission, poor communication between nodes, single function, short service life, inconvenience in maintenance and the like which are existed in a conventional node.

Description

technical field [0001] The invention relates to a wireless sensor node, in particular to a wireless sensor node for remote automatic sampling and air quality measurement. Background technique [0002] With the development of semiconductor technology, computer technology, communication technology and other information technologies and the continuous progress of high technology, people's living standards have been greatly improved, and environmental problems have begun to attract people's attention. The urban population is relatively densely populated, and there are many enterprises around the city. The problem of air pollution from industry and public life has always been a concern of various countries and citizens. Various countries and governments have also been committed to improving the quality of life in cities, and the first step to improving urban air quality is to fully obtain and understand urban air quality parameters. The previous practice is to collect raw data a...
