High requirements for controller communication interface: high-performance controller and communication interface are required to process data, which increases technical complexity and cost.

[0021] Visual positioning method: complex to implement: requires complex image processing algorithms and high-performance computing resources.

[0022] Environmental sensitivity: Vulnerable to lighting changes, occlusion and other environmental factors, resulting in unstable positioning.

[0023] The present invention provides a positioning control device for a rail-type robot for orderly charging of new energy vehicles, referring to Figure 1 As shown in the structure, it includes a control system, a communication interface, an I / O interface, an RFID radio frequency identification, a drive system, a photoelectric switch and a walking mechanism; the control system exchanges information with the RFID radio frequency identification through the communication interface to identify the electronic code of each charging parking space, and senses the operating status of the robot through the I / O interface and the photoelectric switch; the control system drives the robot to move on the walking mechanism by controlling the drive system according to the identified and sensed information to achieve precise positioning of the robot.

[0024] Specifically, the control system is the core of the entire charging robot and is responsible for coordinating and controlling all operations and functions of the robot. The communication interface is used for data exchange between the robot controller and the RFID reader. I / O interface provides input and output functions, allowing the robot controller to interact with external devices. RFID radio frequency identification is used to identify the electronic code of each charging parking space to ensure the correctness of the charging target and the robot's walking position. Drive system enables the robot to move to the specified position. Photoelectric switch is used for state perception during the robot's walking process, helping the robot to slow down at the right time and stop accurately at the target position. Walking mechanism enables the robot to move on the track.

[0025] The present invention realizes high-frequency recognition of the current position of the charging robot through photoelectric switches and RFID radio frequency identification technology, and adjusts the robot's running direction and speed according to the recognition result until it reaches the target position; thereby being able to adapt to positioning technology in various charging station environments (including straight and curved tracks); reducing dependence on expensive hardware and reducing overall deployment and maintenance costs; simplifying the implementation process: creating a positioning solution that is easy to implement and maintain, reducing the demand for complex algorithms and high-performance computing resources; ensuring positioning accuracy and reliability: ensuring that the new technology can meet the precise control requirements of the charging robot under various operating conditions; the present invention's economical, efficient and reliable new charging robot positioning control technology can meet the growing demand for new energy vehicle charging facilities.

[0026] Reference Figure 2 As shown, the present invention provides a positioning control method for a new energy vehicle orderly charging rail-type robot based on a positioning control device for a new energy vehicle orderly charging rail-type robot, which specifically includes the following steps: Step S1: start the positioning process of the charging robot. The robot receives the instruction to start positioning and is ready to perform the task; that is, the positioning start step, starts the positioning process of the charging robot; the robot receives the instruction to start positioning and is ready to perform the task.

[0027] Step S2: Use photoelectric switches and RFID radio frequency identification technology to identify the robot in real time and determine its current position; specifically, it is a high-frequency current position identification step to determine the current position of the charging robot. By using photoelectric switches and RFID radio frequency identification technology, the robot identifies and determines its current position in real time.

[0028] Step S3: Determine whether the robot is running forward or reverse; specifically, determine the relationship between the current position and the target position, so as to determine the running direction of the charging robot. By comparing the current position and the target position, it is determined whether the robot is running forward or reverse. If it is running forward, when the current position is less than the target position, the robot starts running forward, including: Forward high-speed operation: The robot moves quickly to the target position.

[0029] Forward deceleration trigger: When approaching the target position, the robot starts to decelerate. If the current position is greater than the target position during reverse operation, the robot starts to run in the reverse direction, including: Reverse high-speed operation: The robot moves quickly to the target position. Reverse deceleration trigger: When approaching the target position, the robot starts to decelerate.

[0030] Step S4: Make adjustments according to the robot's motion state to ensure that the robot stops accurately at the target position. When reaching the stop position, ensure that the robot stops accurately at the target position; after deceleration, the robot reaches the predetermined stop position.

[0031] Finally, the positioning is completed, the positioning task is completed; the robot stops running, the positioning process is completed; and the robot stops safely during the robot stopping process. After the positioning is completed, the robot stops completely and is ready for charging operation.

[0032] In the present invention, accurate position information is provided by combining photoelectric switches and RFID radio frequency identification to ensure that the robot can navigate accurately. It should be noted in the present invention that when running in forward and reverse directions: the robot selects the correct running direction based on the comparison results between the current position and the target position; the choice of high speed and deceleration: when the robot approaches the target position, it switches from high speed operation to deceleration to ensure accurate docking; the accuracy of positioning: the design of the entire process of the present invention is to improve the accuracy and efficiency of positioning and reduce errors.

[0033] It should be further explained in the present invention that the present invention can ensure the accuracy of positioning by combining photoelectric switches and RFID radio frequency identification, judging forward and reverse operation, and selecting high-speed and low-speed crawling modes.
