Charging pile intelligent control system and control method based on accumulated water level induction

Abstract

The invention relates to a charging pile intelligent control system and control method based on accumulated water level induction. A system application layer comprises a controller and a cloud end, and a system middle layer comprises an RTU communication module and a PLC module; a system sensing layer comprises a water level sensing probe and an acquisition module; a system execution layer comprises an execution switch, an alarm and an operation and maintenance personnel mobile phone; the water level sensing probe senses the water level monitoring height; the acquisition module uploads the water level monitoring height to the controller through the RTU communication module; a controller compares and calculates the water level monitoring height with a plurality of preset threshold values through the PLC module, and sends a control command according to a calculation result; an RTU communication module receives tripping information sent by the controller and uploads the tripping information to the cloud, the cloud sends the tripping information to a mobile phone of an operation and maintenance worker, and the RTU communication module transmits a tripping instruction or a closing instruction sent by the controller to the execution switch; an execution switch performs tripping instruction and closing operation; and an alarm generates sound-light alarm signals. According to the invention, automatic water accumulation alarm and power failure of the charging pile are realized.

Description

technical field [0001] The invention belongs to the technical field of charging piles, relates to the technical field of accumulated water treatment of charging piles, and in particular to an intelligent control device and control method for charging piles based on water level induction of accumulated water. Background technique [0002] With the support of national policies, electric vehicles have been vigorously developed, and the number of charging piles has increased year after year. On the one hand, operation and maintenance personnel and costs increase in direct proportion to the number of charging piles. On the other hand, the status of charging piles directly affects the stable and safe operation of the power grid. As more and more charging piles are connected to the public grid, in order to ensure the safe operation of charging piles, operation and maintenance personnel need to strengthen personnel on duty and safety inspections, and pay a large operation and mainte...
