(1) User management (2) Reading and setting various metering data, management parameters (3) Fee statistics, query, backup (4) Billing, report generation and printing (5) Scheduled meter reading function, daily copy Table times and time can be set (6) can be set "automatic meter reading day" (data freeze)
(7) Real-time meter reading function (8) Automatic timing function (9) Power-off retention function of meter reading data (10) Rate management, multi-rate setting (11) Meter management (12) System and security Management 3. The wireless remote water meter uses wireless meter reading. That is, each water meter sends electronically metered water information to a nearby radio receiver via a radio transmitter mounted on its water meter to complete the meter reading. Meter reading is performed. There is no need for an online connection with the copying device. However, the weak anti-interference ability of wireless communication makes the reliability of the system be threatened. In addition, each water meter must be equipped with radio transceiver equipment. As a result, the installation cost is increased and the technical requirements for maintenance are high.
IV. Advantages and Disadvantages Advantages: The centralized meter reading management is realized, the labor intensity of the meter reading personnel is greatly reduced, and the manpower and material resources of the meter reading work are reduced. Compared with the prepayment meter, it has good reliability and anti-jamming performance; The application of network technology has realized online monitoring; the scope of application is wide, and not only for small-diameter (DN15-25) water users, but also for large-scale water users (DN80-200) can also achieve remote meter reading management.
Disadvantages: The need for a relatively centralized installation of the base table; telephone network, radio, network technology and other transmission methods need to occupy frequency for a long time, need to pay, if the number of centralized installation is small, not economic; cost is higher.
The development direction of smart water meter in use First, the Ministry of Construction of the People's Republic of China promulgated the CJ/T 133-2001 "IC Card Cold Water Meter" industry standard in 2001. It marked the maturity and stereotypes of smart pre-paid water meter technology, and some excellent intelligence has emerged in China. The lack of water resources for pre-paid water meter manufacturers and system integration companies has forced the government and water companies to speed up the implementation and implementation of water price ladders. With the improvement of smart pre-paid water meter performance and price reduction, there will be one in China. Good development.
Second, with the development of science and technology, social progress, advanced technology, high precision, good stability and long-distance transmission meter and smart meter reading system will be the future development trend of the metering.
Some Suggestions 1. The trade settlement water meter is the main instrument that the head office charges users for settlement and has a large quantity, and its use is particularly important. Water meter selection should be based on the principles of “advanced technology, accurate measurement, stable performance, ratio of quality to quality, and efficiencyâ€.
2. With the advancement of science and technology, the development of new technologies is getting faster and faster. The head office should apply advanced technology, good stability, and high-precision measuring instruments to the production and operation of the head office to improve the head office's management and management level. Therefore, the head office should conscientiously do a good job in the introduction of new technologies and new products. Through trials and trials, it will conduct technical and economic analysis of performance and benefits, and provide a scientific basis for the selection of the company's trade settlement water meters.
Concluding remarks: Science and technology are productivity. With the full implementation of “one household, one watch†work, the clearing water meter for the head office will increase rapidly. The use of a large number of ordinary mechanical water meters will add a lot of arduous work and difficulties to the later operations management. The promotion and application of high-precision water meters has undoubtedly promoted the technical progress of tap water metering. With the progress of society and the development of science and technology, we firmly believe that the application of mature high-tech in the measurement of tap water charges will become more and more widespread.
Since we did not carry out on-site inspections of manufacturers and users, and we have limited information and lack of expertise in our collections, the report has some imperfections. Please forgive understanding and corrections. We will continue to improve in the future.
