If the entrance indicator light 11 is green, the vehicle can enter to perform the battery swap operation. The exit indicator light 3 is used to prompt the driver to drive away from the battery swap station. When the exit indicator light 3 is green, it means that there is no vehicle in the battery swap station at this time. When the exit indicator light 3 is red, it means that there is a vehicle in the battery swap station at this time.

[0037] The intelligent camera 13 is used to shoot the picture of the battery swap channel. The picture transmitted by the intelligent camera 13 to the upper computer is used to identify whether the position of the battery pack on the vehicle entering reaches the specified range through the algorithm of the upper computer. The liquid crystal display screen 4 is used to display the picture shot by the intelligent camera 13 and guide the driver to drive the vehicle into the battery swap range. The RFID radio frequency identification antenna 2 is used to receive the information of the battery swap vehicle. The RFID reader is used to decode the vehicle information identified by the RFID radio frequency identification antenna 2 and send it to the upper computer.

[0038] The millimeter wave radar 5 is used to identify whether the vehicle enters the battery swap station. The license plate recognition camera 10 is used to identify the license plate of the vehicle. The laser ranging sensor 7 is used to identify the position of the battery pack and feed back the current battery pack coordinates and angle to the upper computer. The motor 8 and the slide rail 9 are used to carry the laser ranging sensor 7 to move and scan and detect the coordinates of the battery pack. The pedestrian detection camera 12 is used to shoot whether there is a pedestrian in the battery swap channel range and transmit the shot picture to the upper computer. The upper computer identifies whether there is a person near the battery swap channel. If there is a pedestrian, the upper computer will immediately trigger the stop battery swap command.

[0039] The switch is used to transmit video information. The active sound column 1 is used to broadcast the progress, steps and driver operation of the battery swap process. The emergency stop button 6 is used to stop the battery swap process in an emergency.

[0040] Further, the battery station is provided with a battery compartment cabinet, and the front of the battery compartment cabinet faces the battery replacement channel; the front of the battery compartment cabinet is sequentially provided from top to bottom with an active sound column 1, an RFID radio frequency identification antenna 2, an exit indicator light 3, a liquid crystal display screen 4, a millimeter wave radar 5, and an emergency stop button 6; a motor 8 and a slide rail 9 are arranged on the entrance beam of the battery station opposite to the battery replacement channel, and a laser ranging sensor 7 is arranged on the slide rail 9; the slide rail 5 here can be a ball screw slide rail or a synchronous belt slide rail (both are existing structures, which will not be described here); a license plate recognition camera 10 is arranged on the oblique front side of the battery replacement channel; an entrance indicator light 11 is arranged on the side plate at the top of the battery station; a pedestrian monitoring camera 12 is arranged at the top of the battery station; an intelligent camera 13 is arranged on the cantilever beam; an RFID reader / writer, a switch, and a PLC are arranged in the battery compartment cabinet.

[0041] To be specific, the devices in the control human-computer interaction system of the heavy truck battery replacement station are basically installed on the battery replacement station without additional panels, and the devices and wiring do not need to be disassembled when the mobile battery replacement station is transported, thereby improving the transportation convenience and reducing the transportation cost; at the same time, the installation and maintenance work of the human-computer interaction devices is also reduced.

[0042] Secondly, the upper computer, the PLC, and the switch are connected through a network cable, and the devices are remotely controlled by reading or controlling the device state, thereby optimizing the battery replacement process, improving the battery replacement efficiency, making the preparation process before battery replacement simpler and more reliable, and the upper computer monitoring the running status of the system in real time, analyzing the causes in time and giving corresponding solutions when a fault occurs, thereby reducing the downtime of the entire system and improving the running efficiency.

[0043] Furthermore, the intelligent camera 13 captures the battery replacement channel in real time, and through the intelligent camera 13 and the visual recognition technology, the system can determine whether the vehicle is in the battery replacement range according to the actual position of the battery pack, without relying on the specific vehicle model to determine, thereby solving the problem that the battery replacement station on the market can only adapt to a single vehicle model, as long as the size and specifications of the battery pack of the vehicle are consistent with the requirements of the battery replacement station, the battery replacement operation can be successfully performed, thereby expanding the compatible vehicle model range of the battery replacement station and improving the universality and market coverage of the battery replacement station.

[0044] In addition, the intelligent camera 13 captures the picture of the battery replacement channel in real time and displays it on the liquid crystal display 4. The driver can observe the liquid crystal display 4 and stop the vehicle when the battery pack is in the pre-defined battery replacement rectangular frame. If the vehicle is not completely stopped in the frame, the liquid crystal display 4 can remind the driver to adjust the vehicle position through warning frames or text.

Without manual assistance, the driver can easily complete the battery replacement task. This method is more intuitive, and the visual battery replacement process greatly improves the success rate of one-time parking, thereby reducing the battery replacement time, improving the overall battery replacement efficiency, and optimizing the user experience.

[0045] Referring to Figure 4 The specific working process of the control human-computer interaction system of the heavy truck battery replacement station is as follows:

[0046] When the entrance indicator light 11 is green, the vehicle can enter for battery replacement operation. When the vehicle completely enters the battery replacement station, the exit indicator light 3 changes from green to red.

[0047] When the vehicle enters the battery replacement channel, the picture captured by the intelligent camera 13 is displayed in real time on the liquid crystal display 4. The driver can observe the liquid crystal display 4 to adjust the vehicle position. At the same time, the intelligent camera 13 also identifies whether the battery pack is in the battery replacement range to determine whether the driver has parked in place. If the upper computer determines that the vehicle has not parked in place, it will prompt the driver to adjust the vehicle position through the active sound column 1. If the upper computer determines that the vehicle has parked in place, it will trigger the motor 8 to drive the slide rail 9 to work. At this time, the laser range finder 7 carried on the slide rail 9 starts to scan the battery pack horizontally. After the scanning is completed, the obtained data is sent to the upper computer. The upper computer identifies the coordinates and angle of the battery pack and sends the data to the battery replacement robot.

[0048] During the whole battery replacement process, if an emergency occurs and the battery replacement operation needs to be stopped, the emergency stop button 6 can be pressed immediately. The battery replacement robot will stop moving immediately, which is an important safety button to ensure the safety of battery replacement. The pedestrian detection camera captures the battery replacement channel in real time during the battery replacement process. Through visual recognition, if a pedestrian is detected in the battery replacement area, the upper computer will immediately stop the battery replacement process.
