Patent ID: 8866635

Claim:
A smart meter evaluation device that receives a signal according to a predetermined communication protocol in a wireless ad-hoc network including a plurality of smart meters that measure the amount of consumption and acquire meter value data, and evaluates a communication state of the plurality of smart meters, comprising: a receiving unit for receiving a radio-frequency signal and converting the radio-frequency signal into a baseband signal; a demodulating unit for converting the baseband signal into digital data and outputting the digital data as demodulated data; a signal type specifying unit for specifying the signal type of the demodulated data on the basis of header information included in the demodulated data; a communication information acquiring unit for acquiring communication information which is included in the demodulated data and includes at least the meter value data; a signal waveform acquiring unit for acquiring the waveform of the baseband signal; a display unit for displaying the signal type, the communication information, and the signal waveform; a determining unit for detecting whether the signals from the plurality of smart meters collide with each other in one smart meter on the basis of a signal level of the baseband signal.
