New generation of multifunctional prepaid remote water meter

Abstract

The invention discloses a new generation of multifunctional prepaid remote water meter. The multifunctional prepaid remote water meter comprises a rotary-wing type multi-flow mechanical water meter, which is integrated with a water meter base table and a transmission sensor; the rotary-wing type multi-flow mechanical water meter is connected with a single chip measuring and controlling circuit; the single chip measuring and controlling circuit is connected with an executing mechanism; the executing mechanism is connected with an electric control valve; a digital measuring circuit, a single chip main chip and a control circuit are embedded in the single chip measuring and controlling circuit; and the single chip main chip is respectively connected with a liquid crystal display, a transmitting antenna, a building collector, a transcription machine and an external power supply in sequence. The new generation of multifunctional prepaid remote water meter disclosed by the invention has the advantages as follows: simple structure and stable performance are achieved; a prepaid function is achieved; after purchased water quantity is used up, the valve is automatically shut off to remind a user of purchasing water in time; a stepwise-water-price charging function is obtained; remote communication is achieved through telephone lines, wide-band networks, wireless transmission and so on; and the meter of each house is remotely read, so that defect of unreliability for reading data in the traditional remote water meter is fundamentally solved. The phenomenon of water stealing and leakage is eliminated. The new generation of multifunctional prepaid remote water meter disclosed by the invention is widely applied to water supply companies in big, medium and small cities.

Description

technical field [0001] The invention relates to a water meter, in particular to a new generation of multifunctional prepaid remote transmission water meter. Background technique [0002] At present, the remote water meters commonly used in the market are divided into two types: wired remote transmission and wireless remote transmission, but no matter which type is used, their functions are single, and they can only simply solve the problem of automatic meter reading. The problem of difficult charges has not been completely resolved. [0003] Another commonly used prepaid water meter on the market is mostly powered by a built-in battery, but the quality of domestic lithium batteries is generally not good enough. In addition, the smart water meter is used in a humid environment, which easily makes the battery damp, resulting in a lithium battery that does not meet the national standard. number of years. When the lithium battery power is low, the manufacturer can only send so...

AI Technical Summary

Problems solved by technology

If the water meter is installed in the meter well, users must go down to the meter well if they want to check their usage, which is inconvenient and unsafe for users to use

Since this kind of water meter cannot monitor
