The development of charging users and charging industry demands the high requirements for the maintenance of charging equipment. The operation company is particularly urgent in the failure diagnosis, and also in operation and maintenance management with the charging equipment. In order to fit the requests made for the equipment maintenance by the charging users, and deal with the stress to equipment maintenance brought by the developments of charging industry, a system of long-distance operational charging pile which is based on the Manhattan distance remote is proposed （hereinafter referred to as long-distance operational system）.The establishment of this system can greatly improve the operation level of charging pile. The behaviours of operation and maintenance personals can be controlled efficiently, and at the same time, the inspection results of the maintenance personals can be recorded, which provides the effective basis for performance appraisal. For this system is based on the contrastive analysis above the Manhattan distance and the distance that is between the staff and accident locations, it can not only provide an efficient solution, but also economize the human resources and collocate the resources rationally.
