The invention discloses a
wireless automatic meter reading system based on an NGB (
Next Generation Broadcasting) and a control method thereof, belonging to the field of digital
information transmission and
processing based on a
broadcasting and television network and a short-distance
wireless communication network. The
system comprises an information acquiring device, an information receiving and transmitting device and an
information processing device, wherein the information acquiring device is used for acquiring avometer information and transmitting the acquired avometer information to the information receiving and transmitting device; the information receiving and transmitting device is used for receiving the avometer information and transmitting the avometer information to the
information processing device through a
broadcasting and TV wired bidirectional network; the
information processing device is used for transmitting the received avometer information to an information
processing center in a network; and the information
processing center performs
bidirectional communication with the information receiving and transmitting device through the
broadcasting and TV wired bidirectional network. In the invention, a
wireless receiving and transmitting module is connected to the traditional interface of a set-top box or a
digital television, and a user operation interface continues to use the conventional television interaction charging
system, so that a user can inquire information on an avometer,
payment, account bills and the like through the television.
