传统的综合安全防范系统中如门禁、巡更、防盗报警以及火灾报警系统等以往一直采用有线网络传输信号和数据。近年来无线数据传输技术得到飞速的发展,无线数传网络也不断地在扩展应用领域。以往无线数据传输遇到的抗干扰能力差、传输性能不稳定、功耗大和成本高等问题都已经有完善的解决方案。现在已经有多家生产商提供几百上千种无线数传IC,廉价稳定的无线数传网络已经成为现实的选择。相对于传统的有线传输网络,无线数传网络有以下特点:1.减少工程造价,不需要穿墙拉线。2.布线灵活,在通信距离内只要在数据传输的地方安装数传模块就能实现数据传输,每个数传模块都可以兼做通信中继。3.超过
Traditional integrated security systems such as access control, patrol, burglar alarm and fire alarm systems have been using wired networks to transmit signals and data. In recent years, wireless data transmission technology has been rapid development, wireless data transmission network is also constantly expanding application areas. In the past, wireless data transmission experienced poor anti-interference ability, unstable transmission performance, large power consumption, and high cost. All of these problems have been solved. Now there are several manufacturers to provide hundreds of thousands of wireless data transmission IC, cheap and stable wireless data transmission network has become a realistic choice. Relative to the traditional wired transmission network, wireless data transmission network has the following characteristics: 1. Reduce project costs, do not need to wear wall cable. 2. Wiring flexibility, as long as the data transmission distance within the data transmission module can be installed to achieve data transmission, each data transmission module can also serve as a communication relay.
