Several problems in the design of hotel integrated wiring.

First of all, I just graduated from junior college majoring in electrical automation. And I haven't been in this industry for several years. Please forgive me if there is anything wrong.

First, according to your information, I can understand that your friend's wine house is a new house? Or the renovation of the old house?

Second, during the construction period, the design of the circuit diagram can be completed independently. Just distinguish between the main line and the branch line, and then add parameters such as budget voltage to adjust. That would be easy. Because the decoration is anyway, the line can be managed, and these are guaranteed.

Second, if it is the renovation of old houses. Then you need to see the original design or distribution map. After all, it has been shaped and cannot be changed at will. Unless it's a big transformation.

The weak part is easier. You can directly find a decoration company or an intelligent security company. What the other party said has some truth. Because the effect can directly look at the information such as the placement of electrical appliances or furniture. He needs to reserve and embed lines.

In fact, the main loop or utility does not conflict with the control line or weak wire. Or the impact is relatively small, and more often it can be ignored.
