The invention discloses an on-line calibration
system for an
electric vehicle charging
pile. The on-line calibration
system comprises a
cloud server, a positioning module, a charging
pile management module and a charging
pile calibration module; and after user order information is received, a user is positioned through
Bluetooth, the charging pile used by the user is matched according to positioninformation, a
cloud server sends management information to the management module, and the
voltage and current states during charging are monitored in real time. A
data request terminal receives the task request and then sends task information to all the modules, and data are distributed in a unified mode; a plurality of
Bluetooth collecting devices are arranged near the charging pile, the straight-line distances between a target and the
Bluetooth devices are calculated according to the message strength, and the position of the target is determined by collecting the multiple straight-line distances; matching is conducted in a position
coincidence mode, and compared with
modes such as code scanning for
verification, more convenient and quicker effects are achieved; and after the charging task is completed, current and
voltage information is collected for comparison, real-time monitoring is conducted to prevent abnormal charging information, and the whole process of the charging pile iscalibrated online.
