【摘要】 提出了一种基于有线电视机顶盒的燃气无线抄表系统。该系统由具有智能无线燃气表和与之通讯的无线电视机顶盒组成。智能燃气表上的燃气表节点能够定期采集表计信息,以无线方式发送给无线电视机顶盒;无线电视机顶盒将数据通过电视网、互联网传给燃气公司营业平台。燃气公司也可以利用上述逆向通路对燃气表进行诸如关阀等远程控制。基于TI公司的CC2530硬件平台实现了系统硬件。测试验证了系统的可用性。更多还原

【Abstract】 A novel wireless gas meter reading system is presented in this paper.The system consists of 2 kinds of devices,the wireless gas meters and the cable TV set-top boxes that can communicate with the gas meter.The gas meter node,which is a part of the wireless gas meter,collects the meter informs periodically,and sends them to the cable TV set-top box in wireless way.The set-top boxes would encapsulate the information and transfer them to the data server through cable television network.And then the data server would transfer them to the gas company’s operating platform by Internet.Gas company could control the gas meter remotely by using the reverse paths mentioned above.The devices are implemented by using TI CC2530.Testes show it works for both auto metering and remotely controlling.更多还原
