1, basic knowledge of weak current (including integrated wiring, building automation system, office system, communication system, etc. ) need to understand their principles and composition, and it is best to do it independently. This is the basis of learning weak current.

2, design knowledge, this is based on things, you can design, construction, acceptance, training, after-sales and so on according to customer requirements. , preferably design drawings (general CAD will do).

For a project manager who has worked for 5 years, business knowledge is generally necessary. Such as: business negotiation, project management, bidding, various specifications.

Because the design scope of weak current engineering is too wide, it is best to start with engineering construction and give consideration to this design skill. It is recommended to buy some books on weak current (construction, design and specification).
