Automatic remote meter reading system

Abstract

The invention aims to provide an automatic remote meter reading system, which adopts an M-Bus way, simplifies a transmission way and can fulfill the aim of remotely reading a meter with low cost and high efficiency. To achieve the effects, automatic remote meter reading system comprises a master system which is connected with a public utility meter co-reading system and a server. A plurality of public merchandising service devices are also connected with the server. The public utility meter co-reading system comprises public utility meters for reading the information of the public merchandising service devices. The public utility meters are divided into hosts and slaves. The public utility meters in a fixed region comprise a host and a plurality of slaves. An M-Bus master module is arranged in the host, and M-Bus slave modules are arranged in the slaves. Due to the adoption of the technical scheme, a meter bus integrated with the M-Bus modules can conveniently realizes functions of co-reading and remotely reading the public utility meters such as household ammeters, water meters, heat meters and the like.

Description

technical field [0001] The invention relates to a field bus charging method, in particular to a remote automatic meter reading system. Background technique [0002] For a remote meter reading system, the data transmitted on the bus is important data such as water, electricity, and gas consumed by end users. Coupling interference, all slave devices and between slave devices and master devices are isolated from each other. At the same time, it is required that the cost of networking is relatively low, the transmission line does not need to use shielded cables, and in order to save costs, remote power supply should be used to provide power to slave devices to minimize the use of components. To solve these practical problems must adopt a suitable bus structure. For example, the patent No. 03132268.9 "DCPL field bus and network pre-charging bridge of network smart meter metering terminal" discloses a DCPL field bus for network smart meter metering terminal of remote meter readi...

AI Technical Summary

Problems solved by technology

But it requires a separate control host, and an additional junction box needs to be set up on the bus for endpoint transfer

The most troublesome thing is that the water, electricity, and gas terminals of the system need to be customized for special matching. Whether it is the overall new installation or the renovation of the old line, the cost is very high, and it is difficult to popularize

The scope of application is very limited and the cost is too high
