What projects does the weak current project in the community include? What are the optimized construction units?

At present, there are video monitoring, visual intercom, infrared peripheral protection, indoor alarm (smoke, gas, etc.) in weak current projects in residential areas. ), access control, integrated wiring, voice communication, cable TV and other projects.

Weak current engineering is a classification of power application. According to power transmission power, power applications can be divided into strong electricity and weak electricity. Buildings and buildings usually use alternating current below 220 V and 50 Hz. It mainly provides people with electricity and converts it into other energy sources, such as air conditioning, lighting, electricity and so on.

There are two main types of weak electricity in intelligent buildings. One is stipulated by the national safe voltage grade and low-voltage power control voltage, which can be divided into AC and DC, that is, 24v DC power supply and standby power supply for control or emergency lights. The other is information containing sound, images and data, such as telephone, TV and computer.

As a community project, we must keep up with the progress. Many things need to be buried underground (pipelines), and there are also many problems in the combination of street lamps and greening. Large companies, Zhejiang University Network New, Communication Technology, Xinyuan Intelligent and other companies all have the purpose of making big projects.
