Abstract
The invention discloses a wireless power meter reading system having the terminal querying function, which comprises a metering instrument reading unit, a meter reading management unit and a network querying unit. Codes stored in a concentrator in corresponding connection with a power meter data collector, and the address code of the concentrator, are converted into two-dimensional code labels and dynamically displayed. Each two-dimensional code label is endowed with a unique physical address. A single-chip microcomputer transmits the two-dimensional code labels to a power meter data concentrator in the form of radio signals through a first radio frequency transmission module. The power meter data concentrator processes the two-dimensional code labels and then outputs processed two-dimensional code labels to the meter reading management unit through a GPRS module. The meter reading management unit is connected with the network querying unit and is used for verifying the identity of a use. When the user passes the identity authentication, the network querying unit outputs the corresponding query information.
