【背景知识】在现代智能建筑中,输送和控制空调、照明和动力用电等的220V、50HZ交流电系统被称为强电系统;而输送控制电视监控系统、通信设备、智能消防以及音响设备的36V、24V交直流电力系统则被称为弱电系统。由于现代建筑智能化程度的不断提高,弱电系统的应用越来越成为衡量一座建筑物智能化和现代化程度的标尺。而弱电系统也以其复杂的管线铺设和极为精密的技术要求,被形象地称为现代建筑的“神经系统”。我国国家体育场“鸟巢”的弱电工程造价为2.5亿元,是目前世界上造价最高的弱电工程。
Background In modern intelligent buildings, the 220V, 50HZ AC system that delivers and controls air conditioning, lighting, and powering is called a high-power system; while the transmission control TV monitoring system, communications equipment, smart fire and sound equipment 36V, 24V AC and DC power system is called the weak system. Due to the increasing sophistication of modern architecture, the application of weak systems has increasingly become a measure of the intelligence and modernization of a building. The weak system also with its complex pipeline laying and very sophisticated technical requirements, is vividly called the modern building “nervous system ”. China National Stadium “Bird’s Nest ” weak project cost of 250 million yuan, is the world’s most expensive weak project.
