Problems raised by weak current engineering designers in the interview.

As a weak current engineering designer, you need to consider the following five points during the interview:

1. Basic methods of engineering drawing;

2. Skillful use of autocad200x series software;

3. Keep in mind the key points and basic concepts that need to be mastered in the design of "weak current intelligent system engineering" in Design Code (GB/T503 14-2006);

4. The architecture and relationship of six types of intelligent systems specified in Code for Design of Intelligent Buildings (GB/T503 14-2006);

5. Current situation, realization level and future development trend of weak current intelligent systems at home and abroad.

Weak current engineering design scope:

At present, strong current and weak current are collectively called electrical specialty in design units, and only in large design units will they be divided into two groups of people who actually design. Generally speaking, the scope of weak current design is the design of all systems except 220V system.

Doing a good job in weak current engineering design requires not only excellent professional skills, but also certain spirituality.

For example, how to control an air conditioning unit through an automatic control system involves the following knowledge:

The working principle and schematic diagram of this unit, the basic working principle and brand characteristics of DDC, the protocol of network transmission signal, network architecture, wiring design and construction method, system integration knowledge, drawing expression, etc.
