What is the problem of weak current system construction? The weak current system has a high technical content, a long construction period and a complicated process. It belongs to the management of construction, public security, post and telecommunications, radio and television, fire protection, and electrical industry in China. The weak current industry technical specifications are not uniform, there are defects in many links in the construction of the weak current system, and the qualification management and market access are not satisfactory. Unqualified integrators, engineering contractors and suppliers flood the market and are related to weak current projects. There are more problems. 1. Industry characteristics There are many sub-systems of the weak current system, and the technology involves automatic control, communication, computer, electronics, sensors, machinery and other fields. The existing theoretical system, some of the focus issues have not yet been finalized, and there are few engineering construction experiences worthy of reference and promotion Very few; weak current design is easy to be restricted by other professions and personnel in actual projects, and the design can only be fully carried out in the later stage of the project, resulting in tight design time and too late to think carefully; in the implementation of the project, the bidding behavior is irregular, and the system products are changed at will. It causes a lot of waste of design work; the construction drawing is seriously out of touch with the decoration, and the user's requirements are inappropriate and unclear, which makes the designer do a lot of useless work; user functions are changed at any time, which brings a lot of inconvenience to the design. 2. Technical Standard Issues At present, some domestic places such as Shanghai, Jiangsu, Shandong and other provinces and cities have formulated local design standards, and the Ministry of Posts and Telecommunications is also formulating integrated wiring standards, but there is no industry standard or national standard for the entire weak current integration system. form. Based on what standard to design, what grade and equipment level should be achieved, how to choose international technical standards suitable for China's national conditions, how to carry out project quality assessment and acceptance, these are all problems that need to be solved urgently in the weak current integration market. 3. Construction-oriented issues. Many owners, government authorities, some Class A design institutes, large construction units, supervision units, and engineering companies all have misunderstandings about the entire weak current design, and are not very clear about the design procedures, processes, and content. In the whole design 'BatonIntelligent buildings put forward unrealistic requirements for intelligence, and they have countless functions to be realized by the system, showing great randomness; some owners are one-sided pursuit of advanced technology and complete functions; others are seeking their own building capabilities Wearing a 'smart' hat is enough; especially in terms of equipment selection or system integration, it often succumbs to the trend or arbitrarily raises it, resulting in equipment and facilities not operating normally, resulting in a great waste of investment. 4. Qualification management issues Some system integrators under the banner of 'domestic leading, international advanced' under the banner of 'domestic leading, international advanced' under the circumstance of not accepting valid qualifications, contracted projects everywhere, resulting in quality management problems in the design and construction of intelligent buildings across the country. out of control. Nowadays, many companies have obtained smart building design certificates and smart building general contractor certificates through various means, but they do not understand smart systems. The smart systems designed and built make the owners suffer. Some companies At the time of application, they have the ability to engage in intelligence. After a period of time, the flow of relevant personnel makes them unqualified. 5. Market Access Issues Due to the long-term influence of the planned economy, the design units in my country are not flexible enough in their operation and management. Compared with foreign countries, there is a gap in mastering the world's advanced technology. Therefore, most of the domestic intelligent building design market is controlled by foreign design units Occupied by integrators, and more than 90% of the selected intelligent products are foreign products, my country has been restricted by foreign countries for a long time in this technical field, and it has paid a high price for this. There are many kinds of intelligent products abroad, and the various standards are not uniform. Some manufacturers are unwilling to disclose the communication format and communication protocol. Even if they are made public, their openness and content are often subject to many restrictions. In addition, some equipment cannot meet or meet the domestic requirements for fire protection and security. More seriously, there are currently no practical measures to prevent non-compliant products from entering the domestic market. 6. Lack of design talents. There is a shortage of designers with computer, communications, electrical and other professional knowledge, and at the same time rich design experience and skills, and a keen and forward-looking ability of new technologies; some weak current designers work behind closed doors, seriously divorced from reality and users The need, blindly pursuing high standards and high-end design, and the same design, resulting in many weak current projects 'acquired insufficiency'; due to lack of professional knowledge, some weak current designers have failed to achieve integrated management of many integrated systems, and each subsystem is independent of each other. When a global event occurs, there will be no system linkage and centralized resolution of the event; the lack of openness of subsystems designed by some weak current designers brings many difficulties to system upgrades and network interconnection; some weak current designers ignore the impact of equipment on the environment And the requirements of operating conditions make the installation and use of the equipment difficult or leave hidden dangers to the safety of the equipment.
