The existing three-phase meter automatic verification system pallet scheduling method is only suitable for the separate verification of the three-phase smart meters connected by mutual inductance and direct access, and cannot meet the pallet scheduling compatible with the automatic verification system of the three-phase electric energy meter and the electric information collection terminal. However, the pallets and turnover boxes in the existing three-phase meter automatic verification system are only suitable for the three-phase smart meters connected by mutual inductance and direct connection, and are not suitable for carrying electrical information collection terminals, and cannot control electrical information collection terminals. For automatic verification, another pallet needs to be found, so the number of pallets used is large, which increases the investment in production costs, and the current three-phase electric energy meter verification time is about 3 hours, while the electrical information collection terminal takes more than 4 hours, and the efficiency is low . Moreover, it is easy to take the pallets of two different specifications by mistake during use, which affects the normal progress of the detection work, resulting in a reduction in work efficiency.
