弱电系统工程Weak Systems Engineering
智能建筑中的弱电主要有两类，一类是国家规定的安全电压等级及控制电压等低电压电能，有交流与直流之分，交流36V以下，直流24V以下，如24V直流控制电源，或应急照明灯备用电源。第二类是载有语音、图像、数据等信息的信息源。一般情况下，弱电系统工程指第二类应用。
There are 2 types of weak systems in intelligence building. One is safety voltage, control voltage and other low voltage power fixed by the state. They can be divided into the AC and DC. The AC lowers than 36V and the DC lowers than 24V, such as the 24V DC control power, or the back-up power of emergence lights. The other is information source carrying with language, pictures and data. Under normal circumstance, the weak systems engineering refers to the second application.
随着计算机技术的飞速发展，软硬件功能的迅速强大，各种弱电系统工程和计算机技术的完美结合，使以往的各种分类不再像以前那么清晰。各类工程的相互融合，就是系统集成。
With the rapid development of computer technology, the functions of hardware and software become stronger than before. The perfect combination of various weak systems engineering and computer technology makes its past various classifications unclear
like before. System integration is the mutual integration of different kinds of
engineering project.
弱电系统工程主要包括建筑智能化工程和电子工程。
The weak system engineering major includes building intelligence engineering and electronic engineering.
