The invention discloses an automatic verification system and method for a single-phase intelligent watt-hour meter. The verification system comprises a master station, an industrial personal computer, a programmable logic controller (PLC), a roller conveying line, a six-degree-of-freedom robot, a verification conveying line, recognition equipment, pressure-resistant test equipment, appearance inspection equipment, programming equipment, power presetting equipment, error and function verification equipment, load-switch test equipment, reset-key setting equipment, seal equipment, certificate sticking equipment and sorting equipment. The verification method sequentially comprises the following steps of: conveying, meter taking, conveying, recognition, pressure-resistant test, appearance inspection, programming, power presetting, error and function verification, load-switch test, reset-key setting, seal, certificate sticking and sorting. The verification system and the method have high verification efficiency and small labor strength, and the phenomenon of missing detection is not easily generated.
