Redundant autonomous charging system and method for beam field intelligent spraying vehicle

Abstract

The invention discloses a redundant autonomous charging system and method for a beam field intelligent spraying vehicle, and relates to the technical field of power supply of vehicle auxiliary devices. A control system is used for controlling the operation of the trolley, detecting whether the electric quantity of the battery pack of the intelligent trolley is lower than a set threshold value, and starting and stopping charging; a radio frequency identification system is used for identifying the position of the charging pile, so that the intelligent spraying vehicle runs and stops along magnetic lines of force; and a magnetic line navigation system is used for navigating the movement of the detection intelligent trolley to realize the butt joint of the charging head of the intelligent spraying trolley and the charging pile electrode. The charging butt joint is more accurate, and the connection is more stable. A conducting bar is flexibly connected to the screw rod, so that rigid collision between the conducting copper bar and the electrode contact is changed into flexible contact, the conducting copper bar and the electrode contact are further protected, and the service life of the product is also prolonged; during charging butt joint, remote control is achieved through conduction on-off, and the charging process can be controlled by an external control system.

Description

technical field [0001] The present invention relates to the technical field of power supply for vehicle auxiliary devices, and in particular to a redundant autonomous charging system and method for intelligent spray vehicles in beam yards. Background technique [0002] Smart devices are more and more widely used in factories and construction sites. To achieve autonomous and continuous operation, smart devices must realize energy self-supply. Smart devices now mostly use batteries to supply the energy required for operations through self-charging. The core issues mainly involved in independent charging: the accurate docking of the charging plug and the charging pile receiving plate, the safety protection of the charging plug and the charging pile receiving plate. The existing contact charging method cannot adapt to long-term frequent charging operations; at the same time, the charging head or the receiving plate is exposed to the outside, and there are risks of false contact...
