A design of smart meter reading system in strong anti-jamming environment based on Heavside check and thingsof internet was proposed, and the anti-disturbance algorithm was proposed based on Heavside check function and time-frequency analysis. The small embedded system was used to achieve intelligent meter reading terminal, through networkingtechnology the result was transferred to the control center at real-time, the automatic smart metering system was achieved,and the Heavside check was taken for data processing in jamming environment. Finally, the compared experiment was taken out between the check system and the uncheck system. Simulation result shows that the accuracy of meter reading is improved greatly with nice performance of anti-disturbance, and it will be used in engineering application widely.
