摘　　要：针对目前无线燃气表抄表系统中关于集中器数据传输方式单一方面的不足,提出了一款基于"三网"传输方式的集中器。以LPC1768为主控芯片,配以高性能的射频芯片Si4432、以太网控制器ENC28J60以及3G模块EM770W来实现,给出了各模块的具体软硬件设计方法。测试结果表明,该集中器具有数据传输方式多、方式之间无缝切换、抄表可靠精确、抄表区域数据传输无盲点等优点,具有良好的应用前景与推广价值。Aiming at the deficiencies of the current wireless gas meter reading system of concentrator data transmission of the single aspect. A transmission mode concentrator based on ＂three network＂ is presented. The concentrator system design with LPC1768 as the main chip, coupled with high-performance RF chip Si4432, Ethernet controller ENC28J60 and 3G module EM770W, and the specific hardware and software design of each module are given. Field test shows that the concentrator has many means of data transmission; seamless switching between ways, meter reading is reliable, accurate and meter reading area data transmission without blind spots, etc. It has a good application prospect and popularization value.
