[0073] S500, removing the on-board hydrogen tank and placing a suitable hydrogen tank from the hydrogen station tank storage unit 110 on the vehicle body according to the hydrogen tank demand data, confirming the position state between the hydrogen tank and the vehicle body, and locking the hydrogen tank and the vehicle body based on the confirmation result.

[0074] In the step S100, a communication connection between the vehicle data terminal and the on-board data terminal is established. In an embodiment, the step S100 includes:

[0075] The vehicle position information is collected, and it is determined whether the vehicle is located in a region set in the hydrogen station, such as a hydrogen tank replacement region. If the position coordinate data meets the set condition, it is determined whether the user has made an operation for indicating a request for replacing the hydrogen tank. Then, a communication connection between the hydrogen tank replacement control unit 130 and the on-board data terminal is established according to the user operation. For example, the user clicks to access the wireless local area network of the hydrogen station on the communication device interface, inputs the verification information, and realizes the communication connection between the on-board data terminal and the hydrogen station control unit. The wireless local area network includes WIFI communication, Bluetooth communication, etc. The on-board data terminal includes but is not limited to a vehicle machine system with a communication function, a mobile intelligent device connected with the vehicle machine system data, or other terminals with communication and interaction functions.

[0076] In another embodiment, the hydrogen tank replacement control unit 130 in the hydrogen station stores information of the on-board data terminal in advance. When the vehicle reaches the set region, the data communication between the on-board data terminal and the hydrogen tank replacement control unit is automatically realized, and the communication connection between the hydrogen tank replacement control unit 130 and the on-board data terminal is established.

[0077] In order to avoid the failure of the wireless local area network near the hydrogen station and the inability of the vehicle to replace the hydrogen tank, in a specific embodiment, a cloud server 300 can be used to establish a communication connection between the hydrogen tank replacement control unit 130 and the on-board data terminal. That is, the on-board data terminal and the hydrogen tank replacement control unit 130 of the hydrogen station both transmit data to the cloud, and then obtain target data from the cloud. In specific practice, the data to be processed, such as the hydrogen fuel demand data of the vehicle, can be analyzed and processed in the cloud, and then the processing result is directly fed back to the terminal, which shortens the data processing time of the terminal and improves the data accuracy.

[0078] The above technical solution, when the vehicle enters the hydrogen refueling station or other set area, the hydrogen refueling station will automatically seek data communication with the vehicle data terminal to obtain the running state data and hydrogen storage tank demand data of the vehicle, and prepare for subsequent tank replacement operation. Data interaction can also be realized through the cloud server 300. The data processing and interaction work is placed in the cloud server 300, which can more efficiently and accurately analyze the data.

[0083] In the above step S310, the access permission of the vehicle data terminal can be configured in the system, and the user can choose to open the access without prompting or choose to decide whether to open the vehicle data terminal according to the user's selection each time.

[0085] The real-time running state data includes the current start-stop state of the vehicle, hydrogen fuel consumption rate and other data. The historical running data includes the historical driving distance of the vehicle, the average speed of the vehicle during driving, the hydrogen fuel consumption rate and other data. The expected running data is the distance and average speed required for the vehicle to travel in a future set time period. The above expected running data is input by the user or known by the system according to the historical running data.

[0086] Correspondingly, the hydrogen storage tank demand data includes hydrogen storage tank model data and hydrogen fuel remaining amount data in the hydrogen storage tank. The above scheme can accurately match the corresponding hydrogen storage tank for each vehicle according to the actual demand of the vehicle, not only in terms of model, but also in terms of hydrogen fuel remaining amount in the tank, which is beneficial to improve the utilization rate of hydrogen fuel in the hydrogen storage tank after single tank replacement.

[0098] The real-time attribute information of the hydrogen storage tank includes category data of the hydrogen storage tank, remaining amount data of hydrogen fuel in the hydrogen storage tank, vehicle information data associated with the hydrogen storage tank, and historical use data of the hydrogen storage tank.

[0099] The technical solution can arrange the corresponding hydrogen storage tank in preparation before the vehicle to be replaced enters the hydrogen refueling station, which can reduce the queuing time when the vehicle is replaced, improve the efficiency and accuracy of the replacement, and also adapt the most suitable hydrogen storage tank for each vehicle, which is beneficial to improve the utilization rate of hydrogen fuel in the hydrogen storage tank after single replacement.

[0100] In step S400, the vehicle position and running state data are obtained and confirmed, and a control signal is output to release the locking between the vehicle body and the on-board hydrogen tank based on the confirmation result, including:

If the vehicle is located at the set replacement position and is in the replacement standby state, a control signal is output to control the locking device between the vehicle body and the on-board hydrogen tank to release the locking between the vehicle body and the on-board hydrogen tank.

[0103] Further, in step S400, the position state between the hydrogen storage tank and the vehicle body is confirmed, including:

[0104] Receiving the connection feedback of the on-board data terminal and / or the on-board locking device to determine the connection state between the hydrogen storage tank and the vehicle body, and / or collecting image information of the hydrogen storage tank and the locking device to determine the connection state between the hydrogen storage tank and the vehicle body based on image recognition algorithm.

[0106] The hydrogen fuel automobile quick tank replacement method disclosed by the embodiments of the present application changes the existing fixed hydrogen refueling mode to tank replacement type hydrogen refueling, which can significantly improve the hydrogen refueling efficiency and safety. The vehicle operation state data and hydrogen storage tank demand data are obtained through the vehicle-mounted data terminal, which can more accurately configure the vehicle-mounted hydrogen storage tank for different vehicles. The differential tank replacement method also maximizes the utilization rate of hydrogen fuel in a single hydrogen storage tank after single tank replacement.

[0107] To implement the hydrogen fuel automobile quick tank replacement method, the present application also discloses a hydrogen energy automobile intelligent quick tank replacement system, as shown in FIG. 4, which includes a hydrogen refueling station end 100 and a vehicle-mounted end 200 in communication connection with the hydrogen refueling station end 100.

The mechanical jaws are fixedly arranged at the bottom of the gantry crane hanger, and are locked by extending into the hydrogen storage tank rack. Then, the hydrogen storage tank and the rack are transferred to the vehicle body or the hydrogen refueling station tank body storage unit 110 by the gantry crane.

[0113] The position state detection assembly is configured to detect the real-time position of the vehicle and the relative position between the vehicle body and the hydrogen storage tank and output a position confirmation signal. In the embodiment, the real-time position of the vehicle is detected by ultrasonic waves or laser radar. After the vehicle enters the tank replacement area of the hydrogen refueling station, the position state detection assembly transmits real-time position data to the tank replacement control unit 130. During the tank replacement process, the hydrogen storage tank must be accurately placed on the vehicle frame, and therefore the accuracy of the relative position between the hydrogen storage tank frame and the vehicle body must be ensured. In the embodiment, the relative position between the hydrogen storage tank frame and the vehicle body is identified by image recognition. That is, an image collector installed on the gantry crane and / or the vehicle body collects images of the hydrogen storage tank frame and the vehicle body, and the relative position between the hydrogen storage tank and the vehicle body is adjusted in real time according to the image recognition result to ensure that the hydrogen storage tank can be accurately placed.
