Chen Guan water table manufacturers O 13811170697www.deneng123.com www.shuibiao888.com ★ IC card intelligent water meter technical analysis, IC card intelligent water meter is generally placed indoor use, environmental requirements and therefore its use is not high. But this IC card smart meter will generally be placed in a position close to the kitchen, so there is an erosion of water vapor and soot pollution prevention. These issues are now difficult to resolve. Prevent water vapor as long as reasonable sealing technology, general can meet the requirements. Prevent smoke pollution, as long as the IC card technology base to do some additional processing such as dust cover, etc. can be resolved. Here are several important technical indicators for analysis. A battery life indicator. This is an important indicator. Gas meters in this area to solve bad. Some gas meters require users to replace the battery a few months, which is unscientific. Now low-power design solutions have enabled an IC card smart meter does not change the battery operating time of up to eight years or even 10 years. If you reach this level, the user and the water sector will be very convenient. Of course, part of the life of the mechanical metering IC card intelligent water meter and electrical control should be higher, after replacing the battery, should be able to continue to use a longer time. 2, IC card smart meter life. IC card smart meter is a life worth exploring. Because the life of IC card intelligent water meter Theoretically, the shortest life expectancy of the device is determined. Well, life is the shortest part of it? In accordance with national standards, this device is the IC card smart meter, but in fact, IC card smart meter use period of years have far exceeded the national standard, we can see that the standards are set and unreasonable. From now on the actual manufacturing situation, life expectancy index to the manufacturer promises up to 6 years is reasonable. But in fact, IC card intelligent water meter service life of over 10 years is entirely possible. 3, anti-moisture and sealing performance. The above mentioned problem has been sealed. As long as part of the IC card smart meter sealed treatment options, plus some anti-moisture treatment means more than 85% of the technical indicators should be no problem. Anti-vibration performance. IC card smart meter installed to transport and vibration problems will be encountered. So consider this indicator. Generally it is sufficient to achieve a level of 1g. 4, physical damage index. In general, as long as the integrity of the casing using good protective measures in general can meet the protection requirements. Of course, the use of IC card intelligent water meter, which is vulnerable parts of the deck, which is an unsolvable problem. Therefore, treatment should be considered for software protection, so that an attack on the deck of little significance, even if the deck is broken, does not affect the normal operation of the IC card smart meter other parts, but the actual situation, this problem is not serious . Because the IC card intelligent water meter is usually installed in the user's home, using objects clearly, and IC card intelligent water meter is the user's property, there is no special reason, the user does not attack the instrument. Instrument can not be considered to strengthen the anti unlimited offensive, but to intentional infliction of vandalism can be identified and punished accordingly. 5, anti-electromagnetic interference indicator. Electromagnetic interference is not an important indicator. Home environment in such a situation rarely encountered higher than 2000 volts electrostatic field. General electromagnetic strength can not reach normal use will harm people and the strength of other electronic products, so this indicator set at 2000 volts is enough. 6, anti-freeze technical indicators. Anti-freezing problem is a problem of storage and use, for example, in the freezing temperature zone, do drainage treatment to prevent ice up, which is clearly a management problem. Temperature is below zero regardless of the use of IC card intelligent water meter, because the water has frozen, can not be measured. But in the transport and storage process, you may encounter temperatures far below zero, which need to be considered. The value of this indicator should be within a reasonable range of -25 degrees to +50 degrees, the water meter in this range should not be damaged by frost, when the temperature returns to normal temperature, IC card intelligent water meter should be able to work properly. , Water and rely on the concept of water conservation and water use to change the relationship between the price of water is actually not very big, because a lot of people that do not care to pay more money. Thus, hopes to raise the price of water-saving certainly have little effect. Today let's not bad money, but it is limited water resources. Price water, in fact, this is a last resort to price alert people: water scarcity has reached alarming levels, always tighten the string of national water conservation. Thus, changing the water-saving ideas or to work hard, otherwise it can only be a temporary solution. Card meter main functions: 1, pre-paid functions: the user first to buy water use, arrears off valve without water. 2, the card features: a card for the meter and meter control. 3, display synchronization functions: LCD display synchronization and mechanical parts, even if the circuit is faulty LCD screen does not display, it can refer to the mechanical display. 4, prompt alarm function: battery voltage, water may be insufficient, magnetic interference and other fault information on the LCD screen will prompt the police. 5, data upload function: each time a user to buy the water, will be subject to the relevant information management system that allows management to understand the situation and the status of the user's water table. Product Overview: This series of water meter is an instrument used to measure the total volume of water flowing through the pipe, through the first payment, settlement management mode to use, completely changed the way traditional water meter charge. With contactless IC card as the media, it will be all kinds of information from the input table control system, so that the table can be purchased by users of prepaid water supply automatically open the valve, the water to the alarm value or exhausted, that automatically close the valve, interruption of water supply, and LCD display prompts the user to purchase water, the prepaid control; It also records the operation of the transmission table, through the computer, in the systems management software will run statement is displayed, you can implement effective monitoring, thereby changing the past arrears of water, saving water sector and property management of human, material and financial resources, improve management efficiency. The product's base table using a self-developed small and low torque ball movement structure, with high sensitivity and low torque and valve opening; uses advanced microprocessor on the circuit, the meter has a very high anti-interference, reliability, high accuracy and low power consumption performance; their compact design, attractive appearance. Currently the company for different customer requirements to develop a multi-jet small wet water table, small dry water table, small liquid seal water table, four kinds of drip water table series. Each series can provide a table and a card, a multi-card. Specifications: Product performance all in compliance with national standards GB/T778-1996 "cold water", the national industry standard CJ/T133-2001 "IC card water table", the Beijing local standards JJF (Beijing) 33-2003 "IC card cold water meter measuring and testing specifications.
