The invention discloses an intelligent sensor for detecting a wiring state in electric energy meter verification. The intelligent sensor comprises a control circuit, an analog-digital conversion chip, a communication interface, a voltage sampling circuit, a current sampling circuit and a power circuit. The voltage sampling circuit is used for collecting voltage signals on a detecting terminal of an electric energy meter, the current sampling circuit is used for collecting current signals on the detecting terminal of the electric energy meter, and the power circuit is used for powering all the parts. The voltage sampling circuit and the current sampling circuit convert collected alternating-current electric signals into direct-current electric signals, then the direct-current electric signals are converted into digital signals through the analog-digital conversion chip, and the digital signals are output to the control circuit. The control circuit transmits the two paths of digital signals to an upper computer through the communication interface, the upper computer monitors parameter changes of the electric energy meter in real time, and the wiring state of the electric energy meter is judged. Changes of the electric quantity on the wiring terminal of the electric energy meter can be detected in real time, and therefore the wiring state of the electric energy meter is determined, the wiring state of the electric energy meter can be judged fast and accurately, manpower and material resources are reduced, and verification efficiency is improved.
