[0023] The present invention uses ultrasonic sensors to enable the robot to intelligently identify the parking status of vehicles in charging parking spaces while walking, thereby realizing intelligent parking space inspection; and uploading the inspection results to the operation management platform to assist operation decision-making.

[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 ultrasonic sensor. The I / O interface provides input and output functions, allowing the robot controller to interact with external devices. Ultrasonic sensor: used to detect whether there is a car parked in each parking space. The drive system enables the robot to move to the specified position. Photoelectric switch: 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, and then conduct inspections. 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 the combination of photoelectric switch and ultrasonic sensor recognition technology, and adjusts the running direction and speed of the robot according to the recognition result until it reaches the target inspection position, and then inspects the target parking space through the ultrasonic sensor to detect whether there is a vehicle parked in the target parking space; it can adapt to the positioning inspection technology of various charging station environments (including straight and curved tracks); it reduces the dependence on expensive hardware and reduces the overall deployment and maintenance costs; it simplifies the implementation process: creates an intelligent inspection solution that is easy to implement and maintain, and reduces the demand for complex algorithms and high-performance computing resources; it ensures the reliability of intelligent inspection: it ensures that the new technology can meet the precise control requirements of the charging robot under various operating conditions.

[0026] Reference Figure 2a-Figure 5b As shown, the walking mechanism includes a linear guide rail or a U-shaped guide rail or an O-shaped guide rail. When it is a linear guide rail, the parking space is a single-row parking space or a double-row parking space; when it is a U-shaped guide rail or an O-shaped guide rail, the parking space is a single-row parking space; for more specific reference Figure 2a and Figure 2b As shown, it is a top view and a side view of a straight track. In this embodiment, an ultrasonic sensor is used to inspect the target parking space; refer to Figure 3a , Figure 3b This is a schematic diagram of the patrol structure using a U-shaped guide rail. At this time, an ultrasonic sensor is used to patrol the target parking space; refer to Figure 4a , Figure 4b This is a schematic diagram of the patrol structure using an O-shaped guide rail. At this time, an ultrasonic sensor is used to patrol the target parking space; refer to Figure 5a , Figure 5b As shown, a straight track top view and a side view are used. In this embodiment, two ultrasonic sensors are used to inspect the target parking space. At this time, the parking space is a double-row parking space, which can improve the efficiency of the inspection; that is, the present invention can adapt to a variety of application scenarios, including single-row parking spaces, multi-row parking spaces, back-to-back double-row parking spaces, etc.

[0027] Reference Figure 6-Figure 7As shown, the present invention provides an intelligent inspection method for a new energy vehicle orderly charging rail-type robot based on an intelligent inspection device for a new energy vehicle orderly charging rail-type robot, which specifically includes the following steps: Step S1: Start the inspection work of the charging robot. The robot receives the command to start the inspection and prepares to perform the task; Step S2: Use the photoelectric switch to determine the current position of the robot, and use the ultrasonic sensor to detect whether there is a vehicle parked at the current position. Figure 6 As shown, when the walking mechanism is a linear guide rail and the parking space is a single-row parking space or when it is a U-shaped guide rail or an O-shaped guide rail, when the parking space is a single-row parking space, a single ultrasonic sensor is used to inspect the parking space, refer to Figure 7 As shown, when the walking mechanism is a linear guide rail and the parking space is a double-row parking space, two ultrasonic sensors are used to inspect the parking space, and the two ultrasonic sensors are ultrasonic probe A and ultrasonic probe B; Step S3: Determine whether the robot is running forward or reverse on the walking mechanism. If it is running forward, it includes forward high-speed running: the robot moves quickly to the target position, and forward deceleration trigger: when approaching the target position, the robot starts to decelerate. If it is running reversely, it includes reverse high-speed running: the robot moves quickly to the target position, and reverse deceleration trigger: when approaching the target position, the robot starts to decelerate. The robot selects the correct running direction according to the comparison result between the current position and the target position. Step S4: Adjust the robot's motion state according to the inspection situation to ensure the robot's intelligent inspection and upload the inspection results to the operation platform.

[0028] In the present invention, the combination of photoelectric switches and ultrasonic sensors provides accurate location information and inspection information to ensure that the robot can conduct accurate inspections. It should be noted in the present invention that when running in the 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 (parking space to be inspected), it switches from high speed operation to deceleration to ensure accurate parking; the accuracy of positioning: the entire process of the present invention is designed to improve the accuracy and efficiency of positioning and reduce errors.

[0029] It should be further explained in the present invention that the present invention can ensure the accuracy of intelligent inspection by combining photoelectric switches and ultrasonic sensors, judging forward and reverse operation, and selecting high-speed and low-speed crawling modes.

[0030] In the present invention, an ultrasonic sensor using ultrasonic probe A and ultrasonic probe B is used as an example for explanation. Figure 7As shown, the position of the inspection robot is first sensed by the photoelectric switch, and then the position of the target inspection parking space is determined, and the running direction is selected. If the ultrasonic sensor is an odd number, a single probe is used for inspection. If there are two probes, a two-way inspection is used, and then the inspection result (whether there is a car in the parking space or not) is uploaded to the operation platform.
