1、 Industry characteristics and problems

There are many subsystems in weak current engineering, and the technology involves automatic control, communication, computer, electronics, sensors, machinery and other fields. The existing theoretical system, some focus issues have not been finalized, and there are few engineering construction experience worthy of reference and promotion; Weak current design is easily restricted by personnel of other disciplines and units in actual projects, and can only be fully carried out in the later stage of the project, resulting in tight design time and no time for careful consideration; During the project implementation, 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 divorced from the decoration, and the user's requirements are inappropriate and unclear, which makes the designers do a lot of useless work; User functions change at any time, which brings a lot of inconvenience to the design.

2、 Technical standard issues

At present, some domestic provinces and cities such as Shanghai, Jiangsu and Shandong have formulated local design standards, and the Ministry of Posts and telecommunications is also formulating generic cabling standards, but the industry standards or national specifications of the whole weak current integrated system have not been formed. According to what standard to design, what grade and equipment level to achieve, how to select international technical standards suitable for China's national conditions, and how to carry out project quality evaluation and acceptance, these are urgent problems to be solved in the weak current integrated market.

3、 Construction orientation
Many owners, government authorities, some class a design institutes, large construction units, supervision units and engineering companies have misunderstandings about the whole weak current design, and are not very clear about the design procedures, processes and contents. In the whole design "baton", there are differences in the level of designers, and the design division is not reasonable; Lack of understanding of the operating conditions of the adopted technologies and equipment, and false publicity. Some investors put forward unrealistic intelligent requirements in the intelligent buildings that have been built and are under construction, and pay attention to the functions to be realized by the system, showing great randomness; Some owners unilaterally pursue advanced technology and complete functions; Other owners ask their buildings to wear "smart" hats; Especially in terms of equipment selection or system integration, it often succumbs to the trend or rises at will, resulting in the abnormal operation of equipment and facilities, resulting in a great waste of investment.
