Studies On Applications Of Wireless Communication To Home Meter Bus

Home meter bus is a kind of communication techniques developed due to the advance in network communication and intelligent instruments technology, which is widely used in building automation field, including automatic meter reading system (AMRS), etc. AMRS becomes a hot research topic due to the shortage of energy resources. This paper does deep studies into AMRS, which focus on the server-end subsystem and the communication subsystem of AMRS. For the communication subsystem, a new kind of architecture is given which combines the wired and wireless techniques, and the potential problem solutions are also given, including device design etc. For the server-end subsystem, a detailed design of the administrative software is given. The main content of this paper is listed as below:1. This paper gives a brief introduction of home meter bus technique, and then gives some detail examples of home meter bus. The automatic meter reading system (AMR) is introduced as a hot topic of home meter bus. The current research development, the component, the operation mechanism and the communication protocols of AMR is introduced and analyzed.2. The basic knowledge of wireless communication is addressed and some popular wireless techniques are compared. A new kind of AMR architecture is addressed which combines ZigBee technique and home meter bus technique. The topology selection, the design of the device, and the operation mechanism are also given.3. The major part of the server-end subsystem is the administration software, which combines serial port communication technique and database technique. A design of a wireless automatic water meter reading software is addressed. The communication process is modeled using Petri net method, and the database part is modeled using structured analysis method.Finally, a conclusion is made, and the future research directions are proposed.
