An Ad-Hoc Low Cost Wireless Sensor Network for Smart Gas Metering

Abstract

<p class="MsoNormal"> <span lang="EN-US">The monitoring of power consumption has become of a great interest in recent years as well as the innovative technologies available to realize Wireless Sensor Networks (WSNs) have experienced a great growth. While smart metering technologies for electric energy are already established, as sensors power supply comes directly from power lines, WSN nodes for gas metering should necessarily be equipped with long life batteries. The presented work describes a new prototypal low cost WSN designed ad hoc for gas smart metering. The network has a star topology: each sensor node can be completely integrated with standard reed relay gas meter, and it is capable to measure the gas consumption. The information </span><span lang="EN-US">is</span><span lang="EN-US"> sent to the central node (the Access Point, AP) through an RF links. The sensor nodes have been designed with custom electronics and a proprietary firmware, in order to work with a common 3.6 V lithium battery which is able to ensure a life period of about 10 years for each node. Only the AP must be connected directly to electric power. The AP is connected through the RS-232 interface to a control embedded PC equipped with a LAMP (Linux, Apache, MySQL, PHP) framework: it stores all the information coming from each node in a coherent database and allows au</span><span lang="EN-US">thorized users to check the network status using a web interface. The WSN is self-learning and it is capable to detect new nodes joining the network without altering the normal operative flow. Moreover e-mail and SMS alerts can be ac</span><span lang="EN-US">tivated to alert if a node is disconnected from the network or some problems occur. A first prototype of the WSN has been already tested achieving good results.</span><span lang="EN-US"><o:p></o:p></span> </p

Recharging RFID Tags for Environmental Monitoring Using UAVs: A Feasibility Analysis

“…The first description of a multipurpose board developed was already presented in 2012 and described in details in [11]. Three evolutions of the same board, equipped with the most suitable set of sensors, tailored for a specific application, have been already used in three industrial research projects described in [4] [6] [12]. Therefore, in the following, a detailed description of the board used as network node is not reported.…”

Bitmap-Wise Wireless M-Bus Coordination for Sustainable Real Time Energy Management

“…Rorato et al [4] proposed a low-cost smart metering system based on WM-Bus. The proposed network architecture is based on star topology, consisting of access point and meters, and the authors designed low-power firmware to prolong the lifetime over 10 years.…”

“…In particular, WM (Wireless Metering)-Bus [2,3], as a metering network minimizing OSI layer, is recently being regarded as one of the most promising OPEN ACCESS smart metering networks. Therefore, a great deal of research on WM-Bus has been conducted [4][5][6][7][8][9][10][11]. These include research for improving performance, as well as various applications using WM -Bus.…”

Concept for Floating and Submersible Wireless Sensor Network for Water Basin Monitoring

“…The architecture of each node can be easily derived by tailoring the multipurpose node described for example in [7] and applying the power supply consumption techniques reported in [8]. It is to be noted that the energy consumption by the sensors is much smaller than the energy needed to move up and down the probes, taking into account that the data sampling is very low and that the sensors can be used in a low power required mode.…”
