业内人都知道,报警信号在前端探测或触发后,要通过各种通信媒介传送到后端或中心进行处置,才能形成完整的报警系统。目前采用的通信传输包括有线、无线网络两大类,有线方式包括专线、电话线、IP网络等,无线则以中国公共移动通信网技术为主。在我国,有线方式发展较早,技术相对成熟,在报警运营服务实际应用中基本上采用的都是这种方式。近年来,无线网络技术有了快速的发展,如3G、4G通信网络就具备了传输图像、语音等功能,无线技术加上日益普及的GPS(或北斗)定位及其他平台技术,就可以开发出许多移动报警系统或产品。
Everyone in the field knows that after the alarm signal is detected or triggered at the front end, the alarm signal needs to be transmitted to the backend or center through various communication media for disposal, so as to form a complete alarm system. The current communication transmission includes wired and wireless networks in two broad categories. The wired modes include dedicated line, telephone line and IP network. Wireless is mainly based on China’s public mobile communication network technology. In our country, the development of the wired mode is earlier and the technology is relatively mature, which is basically adopted in the actual application of the alarm operation service. In recent years, the wireless network technology has been rapidly developed. For example, 3G and 4G communication networks have the functions of transmitting images and voice. Wireless technologies, coupled with increasingly popular GPS (or Beidou) positioning and other platform technologies, can be developed Many mobile alarm systems or products.
