This paper presents a NGB -based （Next Generation Broadcasting） wireless automatic meter reading system and its control method. The system includes information collection, transmission and processing modules. The information collection module is responsible for collecting the information of the meter of water, electricity or gas, and sending the collected information to information transmission module. Then the information transmission module will send the data information to the processing center through the short range wireless communication and two -way television cable network. The information processing module then sends the collected information to the network processing center. Information processing center can communicate with the information transmission module and control the data acquisition, transmission and other operations of the three meters over the two - way cable television network. The system uses the exist- ing set top box or digital TV interface to access the wireless transceiver module, the user interface can use the existing interactive TV platform, users can query the information of the three meters, the payment and bill through TV sets.%本文提出了一种基于NGB（下一代广播电视网）的无线自动抄表系统及其控制方法。该系统包括信息采集、信息收发和信息处理三个模块。信息采集模块用于采集三表（水表，电表，燃气表）信息，并将采集的三表信息发送给信息收发模块，信息收发模块将接收到的三表信息通过广电有线双向网络传输给信息处理模块，信息处理模块将接收到的三表信息传送给网络中的信息处理中心，信息处理中心通过广电有线双向网络与信息收发模块进行双向通信并控制三表的数据采集和发送等操作。该系统采用机顶盒或数字电视的现有接口接入无线收发模块，用户操作界面将沿用现有的电视互动平台，用户可通过电视机查询三表、缴费和账单等信息。
