A Middleware of Meteorological Data Observation System Based on Wireless Sensor Network

Abstract

The invention discloses middleware architecture applied to a meteorological data observing system, and particularly provides middleware of the meteorological data observing system based on a wireless sensor network. The middleware architecture is used as a bridge for connecting the wireless sensor network and the Internet, can fast conduct data transmission between a sensor network end and a meteorological data observation center, and is flexible in operation and wide in application scope. The middleware comprises a CWSN subsystem and a CPC subsystem, wherein the CWSN subsystem is connected with a meteorological data wireless sensor network, and the CPC subsystem is connected with the meteorological data observation center. The CWSN subsystem and the CPC subsystem are communicated through an ADHOC network. The CPC subsystem comprises a CPC network connecting module, a network self-adaptive module, a CPC automatic update module and a command processing module. The CWSN subsystem comprises a serial port communication module, a CWSN network connecting module, a WSN packet processing module, an extensive makeup language (XML) file processing module and a CWSN automatic update module.

Description

technical field [0001] The invention belongs to the technical field of wireless sensor network middleware, and in particular relates to a middleware of a meteorological data observation system based on a wireless sensor network. Background technique [0002] At present, the meteorological data observation system is divided into wired and wireless according to the data transmission mode. The wired transmission method can realize the collection of meteorological data well, but it has the disadvantages of high line cost, difficulty in laying in mountainous areas, and cumbersome maintenance. The wireless transmission method can provide high service quality and efficient bandwidth utilization while saving costs, so most of them currently use wireless transmission methods for data collection. [0003] The meteorological data observation system usually includes a wireless sensor network, which is a wireless network composed of a large number of stationary or moving sensors, to coo...

AI Technical Summary

Problems solved by technology

After the wireless sensor network is formed, various sensor nodes collect data, but due to the limited resources of each sensor node, it is impossible to have a large enough network communication capability, and the collected data is even less likely to be transmitted to the remote data monitoring center.

However, there are still many problems such as high power consumption, inconvenient data acquisition, poor operability, low level of intelligence, and unstable data communication.
