What is weak current? What are the weak current work in the hotel?

Weak current generally refers to DC circuits or audio, video and network circuits, and the DC voltage is within 32V.

Weak current engineering:

① sound

② Telephone

③ Fire fighting

④ Satellite TV

⑤ Access control

Building and building electricity generally refers to strong electricity above 220 V and 50 Hz, which mainly provides people with electricity.

There are two main types of weak electricity in intelligent buildings:

One is low-voltage electric energy such as safe voltage grade and control voltage specified by the state, which is divided into AC and DC, such as 24V DC control power supply or emergency lighting standby power supply.

The other is information sources including voice, image and data, such as telephone, television and computer information.

The daily work of hotel weak current includes:

1. Banquet acoustics account for a large part of the hotel's daily work. Because the hotel will have several conference halls or multi-function halls, ordinary meetings, VIP meetings, various celebrations and performances. This includes the installation and debugging of audio lighting, telephones, networks and other equipment.

Telephone. Daily maintenance of telephones in guest rooms, offices and public areas. This requires that the weak current should have the foundation of electronic technology, preferably the foundation of home appliance maintenance. Understand the principle of digital analog telephone and TV. In addition, there are DP box jumpers at the program-controlled switch end, daily maintenance of the switch, configuration and operation of common functions, etc.

Third, put out the fire. Now hotels pay more attention to fire fighting. And the fire department will check it regularly, so it will be much easier to outsource the system. If you take care of yourself, there will be a lot of work to do. Short, medium and long-term maintenance, regular system function test, inspection and daily maintenance.

Fourth, satellite TV. This job is relatively easy, as long as you patrol more often, pay attention to TV signals, master satellite transmission technology and some common sense; Polarization angle, azimuth and elevation.

Fifth, access control. Many hotels' access control systems are not real access control systems.
