or into IC era

[REVIEW] Intelligent Control (intelligentcontrols) English abbreviated as \"IC\", which is defined as: in the absence of intervention can be driven independently to achieve the control objectives of the intelligent automatic machine control technology. IC era is the era of intelligent control.

      Intelligent control (intelligentcontrols) English abbreviated as \"IC\", which is defined as: in the absence of intervention can be driven independently to achieve the control objectives of the intelligent automatic machine control technology. IC era is the era of intelligent control.

Since the 1980s, information technology, the rapid development of computing technology and other related disciplines and mutual penetration, promoting science and engineering research to control the deepening, especially in the 21st century, all kinds was the rapid development of science and technology situation, the human aspects have become more sophisticated, the demand and technology conditions have been met to support the case, the control system to the development of intelligent control systems will become a trend.

Turning to solar thermal industry, with the industry\\ s all-round development of are constantly theory, technology, production change. Compared with the early solar water heaters, solar water heater is more mature now, for consumers, more brands of solar water heaters, selective bigger, better read the form, the collector was increased, the quality is more stable; for distributor business, the better to sell solar water heaters, installation of more systems, and more emphasis on after-sales service of; of production enterprises, greater output, the standard is more standardized, itself a development and growth. When a developed to a stage, the product will gradually produce a higher level requirements. People like living in the material reaches a certain stage, based on the requirements will have on the spiritual life, and how to meet the higher demand for solar water heater solar energy into a production factory is a need to continue research and development, to improve an important topic.

The revolutionary control system

Control of human wisdom that higher organisms are the most talked about a desire, so human service products manufactured by the man himself is bound to be controlled. But with the growing awareness and the changing requirements of the control, intelligent control has become the highest current human understanding.

Combined with the continuous improvement of people\\ s demands, solar water heaters to today, has not only a single product, but a saving of energy and produce hot water system. Almost all aspects of this system have been developed, the capacity of water tank used to meet the different number of people, all kinds of vacuum tube collector efficiency has been increased to almost cap, stand to meet the various needs of various types of construction but the CD …… Alone in the control of solar water heater has been no revolutionary change.

Circles in the pan appliances, there is a control technology deeply influenced the later appliance manufacturing, it is wireless remote control technology, this is a technology developed by the military and later civilian-based, large-scale projects by industrial and agricultural use, Since the use of the appliance industry after entering into the homes of ordinary people, has now become an integral control system.

Early television, to conduct various parameter settings, select different channels, different volume must require users to manually adjust himself forward, not only cumbersome but also with the use of frequent, it will affect the entire television system damage. TV remote control system was implanted, when people look at the TV to change channels, volume, set the parameters up front do not have to be adjusted manually, even if it is lying in bed, need only fingers, use the remote control can be completed, and because it does not have to repeatedly touch the TV, but also to some extent, increased the life span of the TV. This revolutionary application allows simple manual TV from almost disappeared, and the current worldwide TV manufacturers have basically no longer produced manually television, and every TV will be equipped with a wireless remote control. The changes in human intelligence while also applied to other products, such as air conditioning, stereo, DVD and so on. This is a big change control system, but also the future direction of human control systems, intelligent inevitable.

Mei Chaofeng look through the chaos of solar water heater industry

    This year\\ s \"Mei Chaofeng\" thunder and no rain, continuous in a hot state to bring a trace of cool weather, but in China\\ s solar water heater industry, is also looking forward to a timely and cleaned up the industry in chaos.

    Production of chaos

    Since the quality of the door incident Haining, solar water heater industry in the production of more attention on the chaos. Successful home appliances products in Hubei Province, there are four quality solar water heater failure, on the State Administration of Quality Supervision, \"Heibang.\" Countries around the solar water heater for Quality Supervision and Inspection Center in Beijing, Hebei, Liaoning, Jiangsu, Zhejiang, Anhui, Shandong, Henan, Yunnan and other nine provinces, municipalities, 60 companies produced 60 kinds of system products were random detection, a total of eight solar water heater product failure, many of whom have a more well-known home appliances business.

    Solar water heater is a low threshold for industry, small artisanal producers flooding, and these small factories in order to reduce costs in the production of the intermediate links are cut corners, streamline the necessary processes. As the saying goes, Clothes make the man, hidden in between the shell and liner insulation material is most likely to cut corners content. Some manufacturers in order to save costs, scrap foam padding directly to the inside, or use of insulation materials used, such as insulation effect can be imagined.

    Sales of chaos

    Solar water heater sales are weather, such as the summer is the off-season sales, some dealers will attack first, while sales of solar water heaters, on the other side is selling appliances or debris. Reporters visited many dealers stores, some stores clutter, poor impression; some even open a solar water heater will be placed in the bracket and put a bunch of the bile duct, without the knowledge of consumers do not see this selling is the solar water heater.

    In the sales cycle, solar water heaters will be worth double the sales from the factory to the original ex-factory price 400 yuan, into the hands of consumers may need more than a thousand. These differences are middlemen to take, but genuine products to consumers in the hands of only a few hundred dollars value, quality and service can not be guaranteed.

    Sale of chaos

    After-sales service is one of the solar industry, a crux. Consumers to buy solar water heater, when the dealer to buy a mouthful of good things can wait until a problem is left to push the right push, if they had to do their own thing. Such as Ms Tang Tsinghua purchased two light brand of solar water heaters, the total price of 7,000 yuan. Ms Tang and the dealer was agreed, the first payment of 5,000 yuan to pay the remaining costs after installation. Subsequently, the dealer sent to Ms Tang, home to install a solar water heater can be installed after a good but not out of hot water. See dealer sent to her home, after her house maintenance staff to repair water heaters do not, have the rest of 2000 dollars, and said that if the remaining money is not paid, they would not repair. Encountered such a service, how can consumers be assured to buy solar water heater?

    Solar water heater industry chaos, which makes large purchases of businesses need to have the problems, how to purchase to quality assurance, service secure solar water heater? I know a number of sales distribution center, such as Mando international building materials market, decorate the city of Wenzhou, Tongxiang new international energy markets. I believe that the new international energy market Tongxiang solar water heaters as a distribution center to ensure quality, service, etc. to provide a reliable guarantee. Settled in the market for domestic famous enterprises of , the market for these companies to provide regular technical exchanges, exhibitions, training sessions, etc., in order to enhance the competitiveness of firms, with the upgrading of competitiveness, product quality, service, and will be improved.

    Solar water heater industry chaos, not only the need for a unified industry guidelines to regulate the market, but also requires all manufacturers, distributors of self-discipline, not blind pursuit of economic interests to the detriment of the interests of consumers in the market at the end.

Shenyang: into the residential property to be crossed the threshold

    Community ye are not allowed to install \"solar energy\"?

    \"I lived in West District, a district of the top floor. Recently, I ordered a , because the results did not use the property on the block. Residential property, officials said, is to let people in residential installation entirely good, if every family are installed on the roof of a variety of solar water heaters, residential is not beautiful. I do not understand, the use of solar energy obviously benefits the country\\ s good, why it so difficult to implement it? \"- Mr. West Portland residents are confused

Area residents

Not to install solar on the property did not understand

The reporter found that many people encounter similar troubles, there are many communities in Shenyang this problem, especially the new residential area, check the owners of property services contract entered into, have raised the \"ban on the top floor installation of solar water heaters \"requirement.

Some owners questioned whether the property has the power to make such a request? Government to promote low-carbon environment, is not contrary to the provisions of Community environmental policy? Solar water heater to meet the low carbon environmental trends, and secondly to save gas. Many selected penthouse owners, often the value of its use of solar water heaters that can be an advantage.

Property companies

Solar cell will affect the appearance

Reporters interviewed the West Lake District residential property company, officials said, do not allow owners to install solar water heaters, because all kinds of solar water heaters on the roof will affect the safety and appearance. Meanwhile, the official also revealed a number of concerns, \"the owners to install solar water heaters in the roof, the roof will damage the waterproof layer, affect housing quality and has an installed solar water heaters, may cause other owners to follow suit, the roof area limited, if allowed to install, in the end how many can be installed? who installed the so easily lead to disputes. \"

Government Deal

Encourage residents to use renewable energy

Ministry of Construction, \"Building Energy\" 15 \"Plan and the 2010 plan\" put forward to the 2015 national household solar water heater penetration to reach 20% to 30%. It is understood that the number of applications of solar water heaters, Shenyang, 18 million units, the user share of 7.6%, well below the national standards required. Life is the trend to promote low-carbon energy, solar water heater installed in the district how to remove the obstacle?

The industry believes that a real estate development, property owners scattered, free installation of solar water heaters, to manage the inconvenience. Only the implementation of mandatory standards measures, requiring real estate developers in the construction process, pre-installed solar energy applications supporting devices, in order to make full access to residential solar water heaters.

Municipal People\\ s Congress official says: It should be of universal application of solar energy for residential area, any property can not prohibit owners to install solar water heaters.

The solution

Preferential policies parties to work together

Although support of national policy, but takes a lot of solar energy into millions of households to work together to create the conditions. In fact, developers and property companies to the various concerns were not insurmountable, developers only need to set aside in the design of residential base and pipe, installation of solar water heaters can be avoided due to security risks. But this will increase the cost of the construction business. Therefore, the relevant departments supporting and encouraging the introduction of policy measures or amendments to relevant laws and regulations, stressed the \"mandatory\", all kinds of conditions do not allow the property to install solar water heaters. On this basis, ask the owner to install according to uniform specifications, we can solve the puzzle of the area unsightly.
