Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicle charging, and more specifically, to a method for positioning a mobile charging pile. Background Art

[0002] In the prior art, the positioning of electric vehicle charging piles mainly relies on single GPS positioning or map-based path planning. However, these methods often have problems of insufficient positioning accuracy when facing complex environments or signal occlusion, resulting in inconvenience and low efficiency of charging services. Specifically, GPS positioning may generate large positioning errors in environments with weak or interfered signals, while map-based path planning may lead to deviations in the planned path due to inaccurate or outdated map data.

[0003] At the same time, the traditional fixed charging pile mode restricts the flexibility and convenience of electric vehicle charging. Since the position of the charging pile is fixed, users need to go to specific charging stations for charging, which not only increases the time cost of users but also may affect the charging experience due to congestion at the charging stations.

[0004] Therefore, aiming at the problems existing in the prior art, there is an urgent need for a more intelligent, efficient and multi-environment adaptable method for positioning a mobile charging pile. This method should be able to integrate multiple positioning technologies, improve positioning accuracy and stability, and at the same time have dynamic path planning and obstacle avoidance capabilities to adapt to complex and changeable charging environments. In addition, this method should also consider the optimization of user experience and provide convenient and efficient charging services. Summary of the Invention

During the movement of the mobile charging pile, the main control unit updates the current position information in real time and adjusts the planned path according to the actual situation to achieve dynamic path planning and obstacle avoidance.

[0009] When receiving the electronic tag information read by the radio frequency identification unit, high-precision position correction is performed by combining other positioning information to achieve precise positioning; when the main control unit receives the electronic tag information, it sends the electronic tag information and the current integrated positioning result to the ground control center so that the ground control center can monitor the position status of the mobile charging pile in real time.

[0010] After the mobile charging pile completes the charging task, the main control unit plans the return path according to the instructions of the ground control center or preset rules to achieve autonomous homing.

[0011] As a preferred technical solution of the present invention, the electronic tag information includes but is not limited to the parking space number, position coordinates, and magnetic field characteristic information. When the main control unit receives the electronic tag information, it matches it with the pre-stored parking space information to further correct the position of the mobile charging pile.

[0012] As a preferred technical solution of the present invention, the other positioning information includes but is not limited to GPS positioning information, inertial navigation information, magnetic field positioning information, and visual positioning information. The main control unit integrates multiple positioning information for position correction to improve the positioning accuracy.

[0013] As a preferred technical solution of the present invention, the environment perception unit includes a radar, an ultrasonic sensor, or a lidar, which is used to perceive the surrounding environment information, such as obstacles, pedestrians, etc. The main control unit considers the environment perception information when planning the path to ensure the safe movement of the mobile charging pile.

[0014] As a preferred technical solution of the present invention, the radio frequency identification unit has multi-frequency identification capabilities and can identify electronic tags of different frequencies to improve the identification rate and positioning accuracy in different environments.

[0015] As a preferred technical solution of the present invention, it further includes a user interaction interface, which provides a touch screen operation, supports voice prompts and remote control functions, and is used to display the status information, positioning results, and charging progress of the mobile charging pile to improve the user experience.

[0016] As a preferred technical solution of the present invention, the main control unit further includes a GPS module, an inertial navigation module, a magnetic field sensor, and a visual sensor, which are used to provide multiple positioning information.

[0017] As a preferred technical solution of the present invention, it further includes a power supply unit, and the power supply unit is electrically connected to the main control unit, the mobile actuator, the communication unit, the radio frequency identification unit, and the environmental perception unit.
