| 摘要: |
| 针对现有远程抄表系统的不足，结合计算机及通信领域的最新科技成果，提出了一种基于LoRa(Long Range)和GPRS(General Packet Radio Service)相结合的网络化远程抄表系统。其无线智能燃气表终端采用超低功耗微处理器MSP430进行智能化设计，完成气表数据采集与处理；采用LoRa技术进行测控组网；集中器和管理中心通过GPRS无线通信网络实现数据的远程交互。最后，给出了抄表系统的可靠性解决方案。实验结果表明，该系统比传统的远程抄表系统能耗低，且更快捷、可靠、方便，可广泛应用于无线远程抄表领域。 |

| Abstract: |
| In view of the shortcomings of the existing remote meter reading system,according to the latest scientific and technological achievements in the field of computer and communication,a networked remote meter reading system based on LoRa and GPRS is proposed.Its wireless intelligent gas meter terminal uses MSP430,an ultra-low power processor,to carry out intelligent design,thus completing gas meter data acquisition and processing;LoRa technology is adopted to set up a monitoring and control network,while the concentrator and management center realize remote data interaction through GPRS wireless communication network.The experimental results show that the system is faster,more reliable and more convenient than the traditional remote meter reading system.It can be widely used in the field of wireless remote meter reading. |
