摘要
为实现对高低压电力用户"全覆盖、全采集",对用户用电信息采集系统的主站、信道、终端都提出了新的要求,通过对现有信道的分析,A地区电力公司提出在230 MHz专网信道上采用自组网技术和4 LEVEL FSK信道调制方式,实现19.2kb/s高速的数据传输,并进一步对组网方式、通信时序、路由等关键技术进行了优化,使用微蜂窝组网方式,通过终端中继消除盲区。在A地区系统中运行专变终端和集中器共100套,实际运行表明采用本方案是可靠的、经济的、实用的。
The target of completing thorough electric power consumption data acquisition of both high and low voltage users poses new requirements for the main station, information channels and terminals of the user consumption data acquisition system. After analyzing the present information channels, the electric power supply company in A area proposes to use ad hoc network technology and 4-level FSK modulation mode to information channels of 230 M private network to realize data transmission at the high speed of 19.2 K. The key technologies of the networking mode, communication sequence and router have been optimized. Microeell networking mode is used and terminal repeat removes the fade zones. In the system of A area, 100 sets of private transformer terminals and concentrators are used and the actual operation verifies that this proposal is reliable, economic and practical.
