摘要
在用电信息采集系统广泛应用无线信道通道的情况下,存在部分用户环境无线信号有盲区的问题。分析了无线GPRS/CDMA信道在用电信息远程信道中的应用,以及无线信号存在盲区的原因,提出了小无线、加装增益天线、采用通信模块外移技术3种进行信号延伸的解决方案。通过对这些技术手段的分析比较,提出实用性建议。
As the wireless technology is widely applied in the transmission channel for the electric energy data acquiring system,exists part of blind areas uncovered by wireless signal in some circumstances.The wireless technology of GPRS/CDMA transmission channel applied in the acquiring system is analyzed,the reasons for existing blind areas are given,three technological methods of micro-power wireless technology,gained antenna and relocation-type communication module are proposed to extend signal for solving solution.The paper compares those technologies and suggests some practical advices.
