In the past few years, my country's major water meter manufacturers have vigorously carried out the research and development of smart water meter technology, but the actual application has not yet formed a scale, and there is still a big gap between the development goals proposed in the smart city development plan. For example, in Shanghai area, although the installation volume of remote meter water meters (including large-caliber ground meters and suite meters) is increasing year by year, manual meter reading is still used as the basis for billing, which has not reached remote meter reading. Generally speaking, as a technology that combines multiple functions such as measurement, sensing, and storage, water meter remote meter reading still has many problems in the specific implementation and application process.

Because of its real-time collection of water meter data, remote water meters can obtain complete water volume fluctuation graphs for analysis and reduce labor costs caused by manual meter reading. It has been recognized by many water companies. After nearly 20 years of development history, Yuanchuan water meters have a wide variety of varieties, and its supporting meter reading systems are also diverse. In this case, how to choose a suitable meter reading product is one of the important conditions for making full use of the advantages of the meter reading system.

During the operation of the meter reading system, it may suffer from various electromagnetic interference from outside the system (such as lightning, radio transmission equipment, high-voltage power grid, etc.), which may cause fatal damage to the meter reading equipment and cause inaccurate and unreliable operation of the system. In addition to avoiding interference sources (such as high-voltage lines, elevators, etc.) when installing the system, the system has a strong anti-interference ability, and it can also remove part of the influence of external interference. Simple construction and short construction period can reduce the labor cost of the system in the early stage. With the increasing labor cost today, it can alleviate the economic pressure of the water company. There are many Yuanchuan water meter manufacturers with different brands and meter reading system functions. The water meter factories are mainly hardware manufacturing, and the research and development of supporting software is relatively weak. Most of them solve the basic functions of meter reading and data transmission and reception, and data integration is standardized and intelligent. Insufficient performance in table management. For the water company, if multiple brands of remote water meters are selected at the same time, it means multiple meter reading systems. Each system must be interfaced with the newspaper installation and marketing system, and the meter reader must also bring multiple meters. The meter reading machine went to the community for collective reading, and the data uniformity and operational reliability were poor, which became a flaw in the popularization and use of remote water meters.

Therefore, it is necessary and practical for the Water Division to take the lead in implementing a remote water meter management system similar to a marketing system. The main problems to be solved are: 1. The remote water meter is used as the terminal device of the collective reading system, and the code is the best The key parameters also determine the formulation of the water meter installation and maintenance process. For different brands and multiple types of water meters on the market, the water company should formulate a unified coding rule based on its own management needs, and the manufacturer shall set and produce according to the rules. 2. Unified bus communication protocol. The data packet rules for collective copy upload and download should also be formulated uniformly to achieve a set of system copy water meters of different brands and models, and the information integration and docking efficiency between the system and the water department is also higher. 3. The remote water meter liberates the meter reading labor. Another feature is intelligent management, such as data timing communication, through data analysis, it can warn users of abnormal water consumption, and can provide warm reminders through WeChat, SMS, etc. Functions such as these are also part of the current content of smart city construction.
