1. What is the smart IC card water meter? Smart IC card water meter is a use of modern microelectronic technology, modern sensor technology, IC smart card technology for water metering and water meter data transfer and new settlement transactions. This is the traditional flow meter generally has a mechanical pointer acquisition and display water features in comparison, is a big step forward. Smart IC card meter of water in addition to recording and electronic display, but also can follow the convention of automatic water control, water and automatically calculate the price ladder, and can be washed with water data storage capabilities.

2. The principle of the basic structure of the smart water meter IC card: IC card water meter water meter and the general appearance of similar appearance, the installation process is basically the same. IC card water meter is very simple to use, from the user’s perspective, it is when the IC card chip to chip in the meter. IC card water meter work process is generally as follows: The amount of IC card is inserted containing a water meter IC card reader, after the computer and download the module identification amount, the valve is opened, the user can normal water. When a user of water, the water collection device starts water collection, and converted into the desired electronic signal supplied to the microcomputer module are measured and displayed on the LCD display module. When the amount of water user drops to a certain value, the microcomputer modules sound the alarm, prompting the user should go to purchase water card payments. If more than the amount of water, the microcomputer module will automatically electrically controlled valve is closed, cutting off the water supply. Until the user inserts the IC card payment has resumed open the valve the water supply.

Prospects prepaid meter and analyze the merits of state

Pre-paid water meters in use often have problems following cases can be drawn through the merits of pre-paid water meter test:
1, abnormal shutdown: In the case of non-exhaustion of water, water shut-off valve, causing the user inconvenience. For example, high-rise towers, if high-frequency supply pressurized water resonance, very likely to cause the valve shut-off, which is mainly manifested in certain valve solenoid valve and poor quality water meters.

2, electromagnetic interference: a magnet close to the water, which will make the output signal can not be pre-paid water meters, resulting in not charging less billing, if the meter shut off valve, indicating anti-electromagnetic interference function, but how to deal with EMI after valve reopen issue, but also the performance merits of the standard meter.
3, Battery life: Many manufacturers nominal built-in lithium life of more than 6 years, less than two years of actual use, more months that is draining the battery manufacturers, is to use a large part of the water meter valve, when there is water inside impurities on the valve open or closed position, and intelligent software design does not have to determine the function, resulting in continuously driving the valve of batteries exhausted. Must identify whether the electricity meter detection alarm function, and how to deal with, if lack of electricity without any treatment, resulting in exhaustion of the amount of electric power and the battery is not enough to close the valve, will allow users of water in vain, water companies and property management sector losses, if Close the valve in advance, letting users is very inconvenient, which is the evaluation criteria.

4, arrears OFF: User home prepaid water meter will do when unaware, or not immediately recharge, causing a sudden disruption of water supply during use, but also how to deal criteria.

Analysis of the advantages of pre-paid water meters

Water shortage is China’s basic national conditions, lack of water to China’s economic development and social life of a huge negative impact. Shortage of water resources to promote the reform of the smart meter industry, these price reforms effectively improve citizens’ awareness of water conservation. Beijing prepaid meter price ladder is to achieve the most realistic option.
Analysis of pre-paid water meter advantages:
(1) can be overcome without electricity live situation as usual.
(2) life of up to six years, lithium batteries can be replaced.
(3) significantly reduce communication costs, the monthly minimum is $ 5.
To sum up: Many companies consider Beijing smart meter site without electricity in the actual situation, recommend the use of lithium battery-powered mode, both overcome scene harsh environments, battery life is also more than 2 years, while communications costs are low , but also to meet the water requirements of the Division for the amount of data. Of course, there is the case in the field of electricity can also be used for AC power supply, all in all, two power supply mode can be selected according to the actual situation.
