What are the weak current projects?

Generally speaking, weak current system engineering refers to the second application. Mainly includes:

1, TV signal engineering, such as TV monitoring system and cable TV.

2. Communication engineering, such as telephone.

3, intelligent fire engineering.

4. Sound reinforcement and sound engineering, such as community background music broadcasting and building background music.

5, integrated wiring engineering, mainly used for computer networks.

Weak current engineering construction problems

I. Industry characteristics

There are many weak current system subsystems, and the technology involves automatic control, communication, computer, electronics, sensors, machinery and other fields. Some key problems in the existing theoretical system have not yet been finalized, and there are few engineering construction experiences worth learning and popularizing. Weak current design is easily restricted by other majors and units in practical engineering, and it is often not fully developed until the later stage of the project, which leads to tight design time and no time for careful consideration; In the implementation of the project, the bidding behavior is not standardized, and the system products are changed at will, resulting in 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 change at any time, which brings a lot of inconvenience to the design.

Second, the technical standards

At present, some places in China, 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 the industry standards or national norms of the whole weak current integrated system have not yet been formed. What standards should be adopted for design, what level and equipment level should be achieved, how to choose international technical standards suitable for China's national conditions, and how to evaluate and accept the engineering quality are all urgent problems to be solved in the weak current integration market.

Third, the problem of construction orientation.

Many owners, government departments, some first-class design institutes, large-scale construction units, supervision units and engineering companies have misunderstandings about the whole weak current design, and they are not very clear about the design procedures, processes and contents. In the whole design "baton", there are differences among designers, and the design division of labor is not reasonable. Lack of understanding of the technology and equipment used and their operating conditions, false propaganda, some investors put forward unrealistic intelligent requirements in intelligent buildings that have been built and are under construction, and have no concept of the functions to be realized by the system, showing great randomness; Some owners unilaterally pursue advanced technology and complete functions; Other owners want their buildings to wear "smart" hats; Especially in the aspect of equipment selection or system integration, it often follows the crowd or increases arbitrarily, which leads to abnormal operation of equipment and facilities and great waste of investment.
