Water meter installed in each household, is a tool to measure the water meter, but also clean up with the user directly to the water sector in product testing. M drinking people’s health, safety and social harmony and quality. In improving the quality requirements of the standard 1 meter per year to review and continuous improvement. 10 years, our company a leader in every Chinese Xu under the correct leadership, scientific and technological level, has made some achievements, upgrade products quickly introduced its eighth generation product. Enterprise-class quality management, a comprehensive water meter upgrade, sell more each year.
Hua Xu smart meters for each one, the former, the law should GB/T778.1 ~ 3-1996 “cold water meter”, JJG162 – 85 meters, “plant and test equipment”, CJ3064 – 1997 “residents of the rules of safe drinking water, measuring instruments,” and other national standards, and through rigorous testing requirements of the relevant product standards, many of the requirements of test items is much higher than the national standard.
So, what is the intelligent water meter then? Intelligent water meter water meter installed in the normal valves, electronic modules, counters, battery. Hua Xu Technology Limited, intelligent water meter, a small size, light weight, low power consumption, high precision, strong resistance to the development of high value-added, high integration, reliability, installation and ease of use, data acquisition, processing, display, protection and automation functions. Electronic products of all we know is the ratio of products, mechanical reliability is low, because it is qualitative in microelectronics are many factors that we do not see, after the occurrence of these devices will be constantly changing together. Therefore, the valve to increase, electronic equipment and product quality, if properly handle the source of the problem.
The Department managed 10 in the use of smart water meter thousands of users in one direction when the development of science, using high-tech products, an inevitable trend. Then, is how to reduce a manufacturer’s product quality issues? This is the modern industry of smart meter, a major issue. Zero Defects is not a smart meter as an early start, at least in high-tech industries, the current inability to produce, if any one dare not say that control of the company: I am smart meters, is Ling Ling defects, quality is 100%. However, users in their daily lives, if not the quality and intelligent instrumentation, often affecting the life of water, it is easy to imagine the bad things.
How to solve the reliability and stability of smart meters water quality problems? First, the product design structure, principles must be followed in mechanics and electronics, mechanical principles of tolerance should be allowed to the principle of electronic or electronic parameters.
Why Use an ordinary meter movement has not yet achieved improvement? The central point is that, according to the movement techniques, fluid dynamics, design principles, so that any one design and the current campaign to improve the conduct thorough. Increased use of smart water meter valve design of the various forms of structure, Hua Xu use of smart meters, ceramic valve has obvious advantages, and by adjusting the material to overcome the greatest weakness of the ceramic valve ensure a strong vibration and shock are not can easily undermine the point of cuimilte will increase the coefficient, but to change the valve on a small ceramic materials. Although the increase is due to the use of power, but the ball compared to a multiple of lower power consumption.
In electronic circuits and procedures should be followed by the first industry-standard requirements, functions should only be used to meet existing needs, as electronic products, more features, the possibility of more problems.
Select the appropriate integrated circuit chip is very important, the capacity of the waste chip space than the General Assembly, have the ability too small, so that the registered pressure beam, thus affecting the overall product function. Electrostatic voltage chip, with a relevant major quality problems.
If there is a simple circuit design, the various functions to meet the industry standards, lower than 3uA static power consumption, not to use, should automatically enter the sleep state, usually. Now it should be the manufacturer of that time, the basic electronic circuits, in order to meet the needs of industry standards, the key is used in chip and circuit design, what kind of quiescent current level.
We can calculate a smart meter circuit quiescent current consumption of 6-year period of energy requirements:
Quiescent current is reduced to 5uA × 24 × 30 fields Theo Shi × 12 × 6 = 25.92 milliamperes years of music
Show 20uA of current the current 24 × Tian Xi Shi Austrian × 30 × 6 × 12 years = 103.68 milliamperes Music
Here, we hope to reduce the power is too large, but it is not only a 1.8Ah battery power small energy concept. Because in the latter stages of battery life, increase the opposition, power consumption is also growing, in addition to the battery itself must be consistent with the energy, the sensor circuit power, power switching valve, credit cards, consumer communications power supply, circuit board capacitor charging power consumption and power factor to cope with read-only voltage. The total capacity of 1.8Ah battery means you can use the energy, usually using the best 80% of battery capacity. The following quiescent current 3uA According to preliminary calculations for the six total electricity consumption of about Jiu Qi ? Hao An modules take many years (off valve 80mA/9s present value terms). This is just the calculated value, no doubt, and unpredictable.
If more than 3uA quiescent current, in the design of discrete communication used to monitor the user’s credit card scanning means of ball to use, then, 80mA of current, because the valves are varied and present unpredictable problems. Usually water pressure (0.4MPa) countries, distribution network, open the valve closed, usually require more than 90 milliamperes current. If the stem, and driven by the deviation of concentricity between the movement, then at the current level is not a master’s degree may well be the level of amps.
Short battery life, and now weak, and once a year as part of any power for two years for other purposes. Problems that may occur until the standard battery, but also because there is a large structural design and manufacturing process itself is flawed. In response to this problem is very common intelligent water meter, people own products Hua Xu’s bi-directional optimization on the one hand, to relatively free self-made lithium batteries, lithium batteries to replace the current all imports, on the other hand, the module hardware and further escalation of the software, from the original 3.6V operating voltage of 3V ratings fall to the present. Greatly improve the lives of smart meters.
Because these modules are equipped with water meters and the environment is not very good, wet one on the installation of smart meters in some parts of the second position is outside the direct installation. Testing of electronic equipment is very difficult. First of all, China Xu module intelligent water meter will be pre-processing surface drying, surface treatment, in order to protect the electronic equipment in order to reduce non-performing model, then install the module on the environmental impact is a good seal to protect. Protection measures can be through a multi-channel module to withstand wet, harsh environment corrosion.
In addition to achieving the protection of the battery modules, and power supply intelligent water meter, so in the harsh environment of the battery life of up to six years, there is no truly reliable protection is very difficult. Defense battery as high and low water-gel main steam temperature, the battery life will be a long gel to reduce gas atmosphere. Battery due to machinery and equipment has been sealed up the protection of sealants used improperly, can not choose sealant, and anti-productive.
Transportation is our product delivery to the means necessary to continue to handle the vibration and the road users. I was dealing with what the business has been at the scene witnessed the unloading line of products. From about 3 meters high high product, was thrown out of loading and unloading personnel, along the cement, the product down the left was broken high natural packaging, the product had a severe impact, this may be the product has been withdrawn. Of course, this may be only accidental discovery, but this phenomenon does not exist in our transportation processes, so that the product is also a potential threat. The installation of some products, but does not measure or do not open or close the valve failure.
Our customer service is the case, the test product is qualified factories, they feel that quality is very good, but installed on a standard telephone complaints, I received a phone call will find a place, of course, very careful to check the factory to create Indeed, the quality is good, but why there is a standard spot market? Find it very strange, and even suspect that their reliable product quality. Because, from the traffic how this happens, because I saw the ill-treatment, or in the process, from vibration, impact, long-term duration of the product more or less intense hurt, then unforeseen problems after installation How? Therefore, we also need to install on-site testing and quality control. Through the detection and control of customs, the product should be installed in 99% of normal operation.
After quality inspection, in order to solve the traffic problem, and the rest is to install product. We know that certainly need to install the product, the user to install the operating system. For users, the operating system’s interface is fully aware that a complaint if the cost of the user’s short-term technical support and maintenance, then the result will be a phone operator, the product quality problems. In fact, the root of the problem does not work, operators can not open the water to sell regular user account. But it is not the operator dare to say that they are opposed to the provision of adequate levels of action, but only the supplier’s responsibility.
Business-to this phenomenon, if left unchecked, it is likely that the region can only install water meters, so far, and may be replaced after the other products. As the operator can understand the right to water sales techniques, they will be trouble with this matter. This is often not the case, because in some located in remote areas, to the list, the traffic is very convenient, so we ignore the post-installation maintenance and technical support. As the use of such devices can be placed on the performance of entrepreneurial examples, but behind the user want to use smart meters, customers switching to the UN Security Council place the poor quality of the product, but have not used Bu-Xing Yue argument that the units can be installation of intent, but such results have heard the idea, and no one dared to install.
At present, accompanied by an extremely important piece of some businesses, products installed in any area, the region’s professional services and technical configuration, after-sales service, product quality and expand the user’s contacts. When the enterprise product sales efforts, certainly big, but it grew and grew. Because they are high-quality products has been extended to the user process. Imagine this: Who needs patients? Needless to say, of course, a doctor. With regard to products and services to the user’s medical team. On one side of the patient’s doctor, users are still worried about?
Intelligent water meter market, China’s most at home? At home watching is very simple, more robust after-sales service, then the company’s biggest positive! As users request service personnel supervision.
