Background
the current remote meter reading modes generally include the following modes:
there is a RS485 bus way of checking meter, there is a bus system ammeter, water gauge and gas meter three meters system of checking meter at present, its water gauge system of checking meter is a water gauge network of checking meter of making up by intellectual water gauge, data acquisition terminal + computer management center + Internet, this kind of technology is mature at present, it is convenient to maintain and construct and have complete executive systems, but its disadvantage is very obvious, it transmits data to adopt the form of wired network, it is comparatively complicated to lay wire, the cost is higher, it is complicated to construct, the engineering quantity is large, and it is difficult to apply in the place where is difficult to lay wire, and each communication link needs IP address, because connect with Internet and suffer hacker's invasion and falsify the user's data easily, the security is relatively poor.
there is also a wireless local area network and internet to form the remote meter-reading network of the ammeter, water gauge and gas meter, in this kind of network water gauge and home gateway are with the point-to-point form carries on the wireless communication, it is a typical wireless local area network, the home gateway is connected with internet through the network card, thus the water company carries on the meter-reading of the water gauge through the internet, its defect lies in: each user needs to be networked or connected with a cell server through setting the cell server, and the cell server is connected with the internet, so that the problems of high management cost and high equipment cost exist, each communication link needs to be provided with an IP address and connected with the internet, the user data is easy to be tampered by hackers, and the security is poor.
The method needs to install a GSM module in each water meter, namely each water meter needs an independent account, so that a large number of GSM modules are needed, a large number of mobile communication accounts are needed, the cost is high, mobile account resources are occupied, the account resources naturally become a bottleneck of mobile communication development, and the feasibility is too low.
The concentrator is wirelessly connected with a plurality of electric meters, water meters or gas meters, and the meters send data to the concentrator; the concentrators in turn send the data to the operator's server. The distance for effective data transmission of the antenna connected with the server is constant, and the number of installed electric meters, water meters and gas meters grows in a geometric index along with the increasing density of population in a certain area. To solve this problem, some current concentrators or water-electricity-gas meters use a multi-channel data transmission method, for example, the signal transmission frequency band can be divided into several channels at 470 and 510 mhz by 150k per channel. At the same time, the server may communicate with the concentrator on a different channel, or the concentrator may communicate with the water, electricity, and gas meter at the same time. However, with the development of cities, too many users are crowded in a certain area, and the method of distinguishing channels for transmission cannot meet the requirement of huge number of users. If multiple water, electricity and gas meters or concentrators communicate using the same channel at the same time, interference in the communication may result.
in summary, according to the requirements of the current internet of things, a remote meter reading system and a remote meter reading method which save channel resources and have low cost are urgently needed.
