零售业防盗报警系统(Electronic Artick Surveil-hace System)阎树EAS系统,在美国及欧洲已经发展、应用超过了20年。它与通常所见的闭路电视系统的区别在于,闭增电视系统主要用于商场整体环境监控,而EAS系统则着重于开架陈列商品的个体跟踪。其技术是使用电子标签附着于物品或商品上,再利用高频电波在某一特定区域内扫描根测这些电子标签的位置,以达到监察、保安、保障财物的目的。EAS系统由三大部分组成:检测器(Sensor)、解码器(De。tivator)及电子孙签(Electronic Label and Tag)。电子标签用以附着或附加于每一件商策上;解码器用
The Electronic Artick Surveil-hace System (European Artick Surveil-hace System) Eucalyptus EAS system has been developed and applied in the United States and Europe for more than 20 years. It differs from the usual closed-circuit television system that is commonly seen. The closed-added TV system is mainly used for overall environmental monitoring in shopping malls, while the EAS system focuses on the individual tracking of goods displayed on shelves. Its technology is the use of electronic tags attached to items or goods, and then use high-frequency waves in a specific area to scan and measure the location of these electronic tags in order to achieve the purpose of monitoring, security, and protection of property. The EAS system consists of three parts: a detector, a decoder, and an electronic label and tag. Electronic tags are used to attach or attach to each piece of information; decoders use
