Who knows the detailed construction of a smart water meter

Beijing Huiyi Water Meter Factory will help you answer: It adopts a special imported microprocessor (MSP430 series produced by TI in the United States) and an ultra-low power consumption design.

One table and one card function: the newly issued user card is inserted into the new table, and the table will automatically identify and save the unique ** in the card, and the ** will be automatically recognized when the next IC card is used, that is, the table will be automatically matched with the card to prevent the use of illegal cards.

Large-screen LCD is always displayed: water volume data, valve status, and battery status are clear at a glance.

Low voltage detection: When the battery voltage is lower, the motor valve will be closed and "under voltage" and "close valve" will be displayed. A new battery is required to be reused.

Anti-counterfeiting function: When the card is reversed or a non-system card is inserted, "card error" will be displayed

Special engineering card: easy to maintain.

Magnetic protection function: when a strong magnetic field is approaching, the watch will display "alarm" and close the valve.

Integrated design: compact structure and beautiful appearance.

Retain the mechanical word wheel display: the whole watch has the function of mechanical and electronic dual display.

4 dry batteries: easy for users to replace at any time.

Intelligent monthly self-test function: ensure reliable operation in various interference situations.

Smart IC Card Water Meter (Smart Cold Water, Hot Water, Medium IC Card Water Meter) Classification:

According to the medium temperature, it can be divided into intelligent cold IC card water meter, intelligent hot IC card water meter, cold water IC card water meter: IC card water meter with the lower limit temperature of the medium is 0 and the upper limit temperature is 50.

Base table + sensor + display loop + output loop.

<><6. Then this water meter is now using 0+ tons of water.

1. The working principle of smart water meters.

By installing a sensing element at a certain position of the reading dial pointer or gear set of the water meter, the mechanical reading of the raw water meter is converted into electrical signal data, and then collected, transmitted and stored, and controlled automatically or manually according to the requirements of the settlement transaction method.

2. Working methods.

When the user's water consumption amount drops to a certain value, the microcomputer module will give an audible alarm, prompting the user to pay the card to purchase water. If the amount of water consumption is exceeded, the microcomputer module will automatically close the electronic control valve and cut off the water supply. Until the user inserts the IC card that has been paid, and starts to open the valve again for water supply.

How smart water meters work:

The internal memory is used to realize the data saving function, and the data can be automatically restored after power-on even in the case of power failure; Adopt battery management function: when the power supply is undervoltage, prompt alarm, replace the battery, when the voltage is lower, the valve is closed, and the valve is automatically opened until the system power supply returns to normal.

Smart water meter is a new type of water meter that uses modern microelectronic technology, modern sensing technology and intelligent IC card technology to measure water consumption and transmit water data and settle transactions. Compared with the traditional water meter, which generally only has the function of flow collection and mechanical pointer display of water consumption, it is a great improvement. In addition to recording and electronically displaying water consumption, the smart water meter can also control the water consumption according to the agreement, automatically complete the calculation of the water fee of the stepped water price, and can store the water data at the same time.

The smart water meter applies high-tech electronic and information transmission technology to the manufacture of water meters, which has changed the traditional meter reading and settlement methods in China to a considerable extent, and improved the level of tap water charging and metering in China, which is a technological progress in tap water metering and charging; Its popularization and application has realized the "buy water first, then use water" and centralized meter reading management, updated the concept of payment of water users, reduced the phenomenon of arrears of water bills, household meter reading, etc., and reduced the manpower and material resources of meter reading of water supply management departments; The water fee can be advanced in advance, which reduces the later operation personnel, improves the management efficiency and the management level of the water department; And the anti-theft performance is better than that of ordinary water meters, and it can fully realize the functions of "prepayment", "stepped water price" and "hoarding water".

There are many types of smart water meters, and the right water meter can be selected according to different needs and places of installation and use. And now the waterworks, and even some enterprises, will use electromagnetic water meters. The electromagnetic water meter can be used in combination with the leakage control system, which is convenient and fast, and can find and deal with problems more quickly, and implement real-time monitoring and management.

The leakage control system independently developed by Qingteng Environment is a high-tech product developed and used in combination with its own electromagnetic water meter products, leading the trend of the times.
