| 中文摘要:针对我国偏远地区、地下室等GPRS信号未能覆盖或者信号较弱的环境,计量自动化系统的现场终端无法正常使用GPRS进行及时通信,在不改动GPRS通信设备和现场终端的前提下,本文利用230MHz技术来解决计量自动化系统GPRS通信盲点的技术难题。在230MHz频段开发提供现场终端上行数据中转服务的设备,一端与数据采集的现场终端交互数据,现场终端上行数据通过230MHz信道转发后,另一端将通过230MHz信道收到的数据转发至GPRS网络,从而传输至主站系统,进而建立良好的通信环境。 |

| Abstract:For the remote areas, basement and other GPRS signals can not be covered or weak signal environment, the terminal equipment of Metering Automation System can"t normal use GPRS communication in time, without changing the GPRS communication equipment and field terminals, this paper using 230MHz technology To solve the GPRS communication blind spot technical difficulty of metering automation system. In the 230MHz band to development equipment provide uplink data transfer service for the terminal equipment, one end interacts with the terminal equipment of the data acquisition, the uplink data of terminal equipment forwarded by 230MHz channel, and the other end forwards the data received by 230MHz channel forwards to the GPRS network, transmit to the master station system, and establish a good communication environment. |
