【摘要】 对燃气表抄表现状进行了分析,以扩频LORA通信为数据传输技术,以光电直读为读数采集技术,在膜式燃气表基础上设计与研发出了一种无线远传智能燃气表,给出了基于此类燃气表抄表系统的设计方案。实践表明,此种燃气表及其抄表系统的使用穿墙能力强、抗衰落、抗干扰、数据保密性高,可极大地提高燃气企业的抄表能力及其抄表率。更多还原

【Abstract】 The performance of the gas meter is analyzed. This paper uses Lora spread spectrum communication for data transmission technology, uses photoelectric direct reading for reading acquisition technology. A kind of wireless remote intelligent gas meter is designed and developed based on membrane gas meter. Practice shows that this gas meter and its meter reading system can make the ability of through the wall strong and can also make the ability of anti fading, anti interference, data confidentiality high. Thus gas meter reading capacity of gas enterprises and its meter reading rate can be greatly enhanced.更多还原
