Internet of Things and Water Metering Wireless Copying and Informatization Development

After a short period of rapid heating, the development of the Internet of Things has become more rational and pragmatic. After reaching a consensus on the bright future, all links in the industry chain are now beginning to address specific issues that govern the development of the Internet of Things. For example, harmonizing standards, reducing costs, and popularizing applications, the Internet of Things is gradually embarking on a steady development path.

The Internet of Things is the Internet of things. It breaks through the virtual limits of the Internet and includes all real things in the world as a form of social life and economic development in a predictable period. The comprehensive popularization of the Internet of Things is facing the bottleneck of technology, public opinion, and policy norms. It has become a strong frontier and field for all industries and industries. The basic livelihood issues of public utilities designing millions of households are also the basic support for the universal popularity of the Internet of Things. The Internet of Things (IoT) attempts of public utilities such as education, medical care, transportation, and energy measurement are the factual basis for the transformation of the Internet of Things into a comprehensive Internet of Things.

Water metering wireless copying and informatization In the field of IoT applications in water management, water metering management has changed with the historical changes in water meter settings.

Historical changes and existing problems in the setting of water meters 1.1 Summary system After people bid farewell to the public water supply sluice, tap water enters the homes of ordinary people, and each household realizes water consumption without leaving home. In the era of socialist planned economy, due to the limited supply of water meters and limited maintenance of the management department, the water meter setting reflects the traditional watch system based on the public ownership of housing. The whole building only has a water meter on the main entrance of the household. The use of more and less money can not be clarified, but the expenses are shared by the households, resulting in waste of water and causing conflicts in the neighborhood.

1.2 One household, one household, one household, and one household are the fundamental means of water conservation, reducing disputes caused by uneven use of water by users. Since most of the small and medium-sized cities' water supply companies use a building or a unit as their billing method, one of the users chooses to sign a contract with the water supply company as a charge representative. Charges represent each household to look up and charge the bills, while the water company charges according to the total list, sometimes leaking pipes or stealing water from individual users, resulting in inconsistent metering and metering of water meters. Water fee.

With the deepening of the market economy system, the building management has turned to the property company, the water company and the property company have signed contracts, and the property company has sent meter readers to check in the households.

Due to household robberies that may result in household robberies, home security is threatened, and there is a privacy problem in the residences, especially for users who have a high degree of home decoration. They are even more repugnant to meter readings.

To this end, in September 1997, the newly revised national code “Code for the Design of Building Water Supply and Drainage” was added to 2.5.8. “The digital display of household water meter or household water meter should be set outside the door”. According to the spirit of "metering and exiting households", design researchers have adopted a variety of practices and have done a lot of research and development. The general practice is to set up the first floor of the household water meter centrally and set up layers, using far-reaching water meters, metered water meters, and other charges.

The water meter exits households, solves the privacy and safety problems of households, and reduces the labor intensity of meter reading personnel.

1.3 The multi-listing system of one household With the improvement of the people's living standards and the introduction of the water resources protection and control policy, there have been many water problems in the use of water. In addition to the traditional water pipes that people use for washing and washing, there are also direct drinking water pipelines. , Living miscellaneous water pipes (used only for flushing feces), hot water supply pipes (bathing water) and other systems.

As for the bottom-end housing business, it involves the same household, but it has the points of commercial water and civilian water use. The use of water is different.

Modern buildings have a large living area. Some health housing projects require one kitchen and two bathrooms, as well as balcony water. There are four points in a common water use. The layout of the building cannot be that these water points are all arranged together. One household and one table will make the indoor pipes criss-cross and spread all over the house.

No matter whether it is one household or one family, it is the outdoor measurement problem. It is also a hot spot in the water for buildings.

Water management outdoor metering methods With the appearance of household water meter forms, metering methods such as setting and layering of the water meter at the first floor of the household, and metering methods such as remote metering and metered water metering have emerged, but due to nuisance and meter reading Convenience, cost recovery, real-time monitoring and many other factors, as well as technical factors and the reasons for the development of social life, the remote measurement method has become the mainstream method of water energy measurement management in the current and predictable period.

Water metering wireless remote metering method refers to changing the ordinary water meter to a remote water meter on the basis of the traditional water meter, or modifying the meter on the original meter to enable remote transmission. The remote water meter is equipped with a micro power wireless remote transmission device, which can send sensing information (user house number, water consumption and other original information) to the corresponding password router, concentrator and data center, and through the GPRS/CDMA channel. The information is transmitted to the computer software terminal for data copying, and the water meter and the pipe network operating status are recorded in real time. When the remote transmission signal line is destroyed, the system automatically stores alarm records and clock records to ensure the safety of the system.

The current wireless remote water meter reading metering method has been upgraded and upgraded on the basis of the original. It can not only realize the function of realizing the monitoring of the pipe network in real time but also realizes the prepayment of the card table. Charging function, and based on this, a humanized SMS reminder fee reform was carried out. Even if the fee reaches the limit, SMS notification will be performed and the valve closing operation will be implemented after the data is returned to zero, which is safe and reliable.

A slight modification of the traditional water meter or replacement of a water meter can achieve accurate measurement without leaving the household. It is the development direction of the water meter setting. It also fundamentally solved the difficulties of meter reading and payment. Using this method, the meter reading personnel's labor intensity is the least or even zero. The staff can get the required data and user water status in real time through the computer without leaving the office. The various data are accurate and reliable, and online printing can be implemented. It can make scientific and reasonable judgments based on the data and use it as the basis for energy allocation and scientific measurement, and it is in line with the current energy conservation and emission reduction energy-saving social goals. Since then, water metering management has also achieved informatization, in which everything involved is connected and becomes a small-scale Internet of Things.

The emergence and rapid development of Internet of Things and water metering wireless copying and informatization are closely related to the water management measurement management in public utilities. The informatization of water metering, that is, the wireless remote water metering and collecting system, has always been engaged in the Internet of Things business in the field of water metering management, and the Internet of Things has enabled water metering information to be “justified”.

Water wireless remote transmission and recording systems have also faced difficulties in transmission signal instability, transmission distance, signal blind spots and other technological bottlenecks and policy scarcity. However, with the improvement and breakthrough of technology, wireless remote transmission technology problems have been solved. Fundamental solutions and national policies were also obtained with the official implementation of the "House Remote Metering System" and the "Technical Regulations for the Application of Remote Metering System for Residential Houses" published by the Ministry of Housing and Urban-Rural Development on June 1, 2010. Due specifications and guarantees.

Liaoning Diabin Mountain Intelligent Remote Water Meter Replacement Project is a large-scale practical project for water measurement and internet of things. The project uses 7000 wireless remote water meters to replace the aging mechanical watches. The meters of every household are connected to the wireless network composed of the Wamr Net System. The wireless remote water meters and system routers and the building concentrators of each household. The data center transmits the data in order according to the password, and uploads it to the computer terminal through the GPRS/CDMA channel so that the meter reader sitting in front of the computer can copy and count the data. The water wireless remote transmission network formed in Diaobingshan City is the local Internet of Things for water metering management. The successful implementation of the Diaoping Mountain meter reading system has promoted the development of local water metering Internet of Things and has benefited thousands of local residents.

According to the planning requirements of the well-to-do residential district proposed by the Ministry of Construction, in the future, unified plans should be made for newly built and reconstructed dwellings, and the unified management of water, electricity, and gas should be gradually implemented to realize automatic computer monitoring, measurement, and charging. Tap water meter reading home to meet the requirements of the overall development of the society, automatic copying system to incorporate advanced information technology, electronic technology, communications technology, etc. into the management of business fees of water supply companies, improve the management level of water supply companies, and increase business charges. This is a manifestation of the modernization of the energy management system. Under the promotion of relevant national policies, the intelligentization of civilian meters has become a general trend. With the constant maturity of the industry's technical standards, the management level continues to increase. It is believed that in the near future, the remote meter reading system will be continuously improved and matured, and the meter reading system will usher in a period of great development. The great development of remote meter reading systems and the vigorous construction of long-distance networks will surely achieve an increasingly large range of energy measurement IoT. The realization of the Internet of Things in the field of utilities will be just around the corner!
