Method and system for remote meter reading of water meter and intelligent water meter

Abstract

The invention provides a system and a method for the remote meter reading of a water meter and an intelligent water meter which is applied in the system for the remote meter reading of the gas meter. The system and the method for the remote meter reading of the water meter and the intelligent water meter do not rely on internet, and are high in safety performance, with no need for excessive internet protocol (IP) addresses and excessive mobile communication identification resources and low in cost. The system and the method for the remote meter reading of the water meter and the intelligent water meter are applied, no internet is relied on, so that hackers are not easy to invade, safety performance is high, and no excessive IP addresses are needed. One mobile communication identification can be connected with a plurality of intelligent water meters, so that occupied mobile communication identification resources are less, not every intelligent water meter is need to be provided with a mobile communication module (such as a global system for mobile communications (GSM) module), and cost is low.

Description

Technical field: [0001] The invention relates to the communication field, in particular to a water meter remote meter reading method, system and intelligent water meter. Background technique: [0002] At present, there are generally three types of remote meter reading methods for water meters: [0003] 1. RS485 bus meter reading method, such as Figure 4 Shown is a three-meter meter reading system of bus-based electric meter, water meter and gas meter. Its water meter meter reading system is composed of smart water meter + data acquisition terminal + computer management center + Internet to form a water meter meter reading network. This technology is currently It is relatively mature and has a complete implementation system for maintenance and construction convenience, but its shortcomings are also obvious. It uses the form of wired network to transmit data, the wiring is more complicated, the cost is high, the construction is complicated, and the project volume is large. I...

[0003] 1. RS485 bus meter reading method, such as Figure 4 Shown is a three-meter meter reading system of bus-based electric meter, water meter and gas meter. Its water meter meter reading system is composed of smart water meter + data acquisition terminal + computer management center + Internet to form a water meter meter reading network. This technology is currently It is relatively mature and has a complete implementation system for maintenance and construction convenience, but its shortcomings are also obvious. It uses the form of wired network to transmit data, the wiring is more complicated, the cost is high, the construction is complicated, and the project volume is large. It is also difficult to apply in places where wiring is difficult, and each communication link needs an IP address. Since the connection to the Internet is easily attacked by hackers and tampered with user data, the security is poor

[0004] 2. If Figure 5 It is a remote meter reading network of electric meters, water meters and gas meters composed of a wireless local area network and the Internet. In this network, the water meter and the home gateway perform wireless communication in the form of point-to-point, which belongs to a typical wireless local area network. The home gateway passes through The network card is connected to the Internet, so that the water company can read the water meter through the Internet. Its defect is that each user must be connected to the Internet, or by setting up a community server, each user is connected to the community server, and the community server is connected to the Internet. There is also the problem of high management costs and equipment costs, and each communication link needs an IP address, which also needs to be connected to the Internet, which is easy to be attacked by hackers and tamper with user data, and the security is poor.

[0005] 3. If Image 6 It is a meter reading method that uses a mobile communication module for electric meters, water meters, and gas meters. It uses a GSM module that is directly installed in the water meter, and directly transmits data to the water company through the mobile public network. This method needs to be GSM modules are installed in each water meter, that is, each water meter needs a separate account. This not only requires a large number of GSM modules, but also requires a large number of mobile communication accounts. The cost is relatively good, and it takes up mobile account resources, which will naturally increase Become the bottleneck of mobile communication development, the feasibility is too low

This method requires more equipment, the cost is too expensive, and it is not advisable
