13 to 15 are schematic flowcharts of a replacement method for a hydrogen storage tank exchange system in an embodiment of the present invention. The replacement method includes: the mobile terminal of the first user sends request information to the platform management system, and performs Reservation of the hydrogen storage tank, request to replace the hydrogen storage tank, and bind with the hydrogen storage tank; when the first user arrives at the hydrogen storage tank, the mobile terminal of the first user scans the electronic identification label of the hydrogen storage tank, and establishes a connection with the exchange cabinet Contact; when the first user puts the hydrogen storage tank into the exchange cabinet, identify the electronic identification label of the hydrogen storage tank to determine whether the hydrogen storage tank meets the requirements; if so, eject the full bottle of hydrogen storage tank; and move the exchange cabinet or the first user The terminal uploads the number of remaining full-bottle hydrogen storage tanks in the exchange cabinet to the platform management system; when the number of remaining full-bottle hydrogen storage tanks in the exchange cabinet is less than the threshold, order information is generated, and the management platform sends the order information to the The second user near the exchange cabinet; if there is a second user who confirms the order information, the second user will go to the exchange cabinet to replace the full bottle of hydrogen storage tank and take away the empty bottle of hydrogen storage tank; otherwise, the order information will be sent to Canada For the second user of the hydrogen station, the hydrogen refueling station will send the second user to the exchange cabinet to replace the full bottle of hydrogen storage tank and take away the empty bottle of hydrogen storage tank; the second user will transport the empty bottle of hydrogen storage tank to the hydrogen refueling station for storage. Hydrogen filling of hydrogen generators.

In a further embodiment, the method in the background management part further includes: obtaining the hydrogen content in the hydrogen storage container and the position information of the hydrogen storage container; obtaining the urgency of the replacement of the hydrogen storage container based on the hydrogen content in the hydrogen storage container; judging Whether the degree of urgency meets the first judgment condition, if the next step is performed, otherwise, the hydrogen content in the hydrogen storage tank is re-acquired; the request information sent by the mobile terminal of the first user is obtained, and the request information includes whether the first user agrees to replace the storage tank. The location information of the hydrogen generator and the destination of the first user; if so, send the route to the hydrogen exchange station to the mobile terminal of the first user; otherwise, prompt the first user to replace the hydrogen fuel electric vehicle, and send the information to the first mobile terminal Send the route to the nearest stop.

It can be understood that a pressure checking device is preset in the hydrogen storage tank when it leaves the factory to detect the hydrogen content of the hydrogen storage tank. The launch module transmits information to the platform management system. There are various means for obtaining the position information of the hydrogen storage tank, such as obtaining the position information of the first user, the position information of the shared hydrogen fuel electric vehicle, or installing a positioning device in the hydrogen storage tank. Obtaining the location information of the shared hydrogen fuel electric vehicle indirectly obtains the location information of the hydrogen storage device.

The classification standard of the degree of urgency needs to be comprehensively judged according to a variety of factors such as the type of hydrogen fuel electric vehicle, the type of hydrogen storage device, and the volume of the hydrogen storage device, so no further restrictions are imposed. For example, when the hydrogen content of the hydrogen storage tank is greater than 40% of the initial content, it indicates that the hydrogen fuel is sufficient; when the hydrogen content of the hydrogen storage tank is less than 40% and greater than 12%, it indicates that the hydrogen fuel is insufficient, and the storage tank needs to be replaced. Hydrogen tank; when the hydrogen content of the hydrogen storage tank is less than 12%, it shows that the hydrogen fuel is seriously insufficient, and the use is suspended.

The first determination condition is that the hydrogen content of the hydrogen storage tank is within a preset range; it is mainly used to screen out that the hydrogen fuel in the hydrogen storage tank is insufficient, the hydrogen storage tank needs to be replaced, and the remaining hydrogen fuel is sufficient to ensure the sharing of hydrogen fuel electric vehicles. Continue to ride a predetermined distance, where the predetermined distance is related to the navigation distance of the shared hydrogen fuel cell to the nearest hydrogen exchange station. For example, the navigation distance between the shared hydrogen fuel electric vehicle and the nearest hydrogen exchange station is 5km. Preferably, the predetermined distance needs to be greater than the average driving distance and the distance between the shared hydrogen fuel cell and the nearest hydrogen exchange station. , can be 5.5km, 6km, 7km.

When the mobile terminal of the first user establishes contact with the platform management system, the information about whether the emergency degree meets the first judgment condition is obtained; if not, it is obtained again; otherwise, the first instruction is output, and the first instruction Whether the first user agrees to replace the hydrogen storage by himself; if the first user agrees to replace the hydrogen storage, a second instruction is output, the second instruction requires the first user to input the location information of the destination, and the location information is transmitted to the background server ; The first user refuses to replace the hydrogen storage device and prompts the first user to replace the hydrogen fuel electric vehicle.

Wherein, the first user is a user who uses the shared hydrogen fuel electric vehicle. The first mobile terminal may be a mobile device such as a user's mobile phone, a Bluetooth bracelet, or a tablet. When the user scans the QR code or RFID on the shared hydrogen fuel electric vehicle or hydrogen storage device to establish a connection with the platform management system, in order to simplify the operation steps, the car rental APP, applet and the platform management system can be directly used for data exchange. When the hydrogen content of the hydrogen storage tank is within the preset range, the user's mobile terminal will receive a message whether to agree to voluntarily replace the hydrogen storage tank. location information.

At the same time, in order to increase the user's enthusiasm for participation, the user's credit system score can be appropriately improved, or incentive policies such as discounts can be given when the car return order is settled.

In a further embodiment, in order to improve the replacement efficiency of the first user, the background management platform further includes path planning. Specifically, the method for determining the optimal path includes the following steps: determining the serviceable range of the hydrogen storage device; and determining the optimal path.

In a specific embodiment, the method for determining the serviceable range of the hydrogen storage device includes the following steps:

Step 1. Determine a first reference point. The first reference point is that in a plurality of possible directions, the position information of the hydrogen storage tank is used as the starting point, and the navigation distance from the starting point is equal to the hydrogen fuel electric vehicle. Multiple points of the maximum travel distance; specifically, the possible travel direction is centered on the hydrogen storage tank and diverges to all directions. In order to simplify the algorithm, the segmentation can be performed at a predetermined angle to generate a certain number of possible directions of travel. It should be noted that due to the limitation of road section planning and service area, redundant datum points may be formed, so redundant datum points need to be deleted in the design process.

Step 2: Screen the second reference point, the second reference point is the first reference point located on the road; the serviceable range should be located on both sides of the road, so that the first user can go to the hydrogen exchange station to replace the storage tank. hydrogen generator. Therefore, it is necessary to determine that the first reference point and the determined boundary are located on both sides of the road, so as to obtain the second reference point.

Step 3: The closed range formed by connecting the first navigation paths between two adjacent second reference points; the acquisition of the first navigation path can be obtained from a third-party navigation server, and the platform management system will The two reference points are merged and connected to form a closed range, which is the maximum activity range of shared hydrogen fuel electric vehicles.

Step 4: Calculate the overlapping range of the closed range and the service range of the hydrogen fuel electric vehicle to obtain the serviceable range of the hydrogen storage device. Since the position of the hydrogen storage device is restricted by the service range of the electric vehicle, the serviceable range of the hydrogen storage device is the intersection of the maximum activity range of the shared hydrogen fuel electric vehicle and the service range of the hydrogen fuel electric vehicle.

Since there will be some redundant points in the serviceable area of the hydrogen storage, for example, at the boundary of the closed area, but the area that the shared hydrogen fuel electric vehicle cannot reach, the closed area needs to be further revised. A method for determining a navigation path, comprising: S621, acquiring a second navigation path, where the second navigation path is the closest navigation path between the starting point and the second reference point; S622, taking the road segment in the second navigation path As a reference, the nearest navigation path between two adjacent second reference points is obtained, which is the first navigation path. This design ensures that the points within the serviceable range of the hydrogen storage device are all areas that can be reached by shared hydrogen fuel electric vehicles.

In a specific embodiment, the method for determining the optimal path of the hydrogen storage tank includes the following steps: acquiring a first path, where the first path is based on the position information of the hydrogen storage tank as a starting point, and the first path The location information of the user's destination is the end point to generate a travel path; the second path is obtained, and the second path is based on the location information of the hydrogen storage device as a starting point, and all hydrogen storage devices within the serviceable range of the hydrogen storage device are The position information of the hydrogen exchange station of the generator is the progress path generated by the end point; the overlapping path is calculated according to the first path and the second path; the second path with the highest degree of overlapping path and the hydrogen exchange station corresponding to the second path are obtained Obtain a third path, the third path is a progress path generated with the position information of the hydrogen exchange station corresponding to the second path as the starting point and the position information of the destination of the first user as the end point; The second path with the highest degree and the third path are accumulated to obtain the path to the hydrogen exchange station, and the path information is transmitted to the first mobile terminal.

It should be noted that, in order to reduce the amount of data transmission and improve the efficiency of data transmission, the map can be directly loaded by the first mobile terminal, and the backend server transmits the optimized path, so that data can be exchanged more timely and effectively.

In a further embodiment, since the above replacement method will inevitably lead to a long-term failure to replace a small amount of hydrogen storage, the method further includes: obtaining the hydrogen content in the hydrogen storage device and the hydrogen output efficiency of the hydrogen storage device; determining Whether the hydrogen content of the hydrogen storage tank is lower than the preset value, or the hydrogen output efficiency of the hydrogen storage tank is too low or too high; the preset value is whether the hydrogen fuel in the hydrogen storage tank can no longer support the shared hydrogen fuel electric vehicle The nearest hydrogen exchange station is selected, and the shared hydrogen fuel electric vehicle has been parked for a long time due to the hydrogen storage, and no one is using it; if so, generate order information and output the order information to the mobile terminal of the second user; Obtain the hydrogen content in the hydrogen storage device and the hydrogen output efficiency of the hydrogen storage device; the second user is the daily maintenance personnel of the shared hydrogen fuel electric vehicle, prompting the maintenance personnel to replace the hydrogen storage device, so as to improve the shared hydrogen fuel electric vehicle utilization rate.

In a further embodiment, the method located in the background management part further includes: acquiring the quantity and location of the full-bottle hydrogen storage tanks in each exchange cabinet; calculating the priority level of each exchange cabinet that needs to be replenished and replaced; and judging whether the priority level is greater than For the first threshold, if delivery information is generated, and the next step is performed, otherwise, the number of full-bottle hydrogen storage tanks in the exchange cabinet is re-acquired; the location information of the mobile terminal of the second user is obtained, and the second user that meets the preset conditions is screened; push The first request information is sent to the mobile terminal of the second user; the first request information includes delivery information, and the position and priority of the exchange cabinet; the first feedback information sent by the mobile terminal of the second user is obtained, and the The first feedback information includes the selection of the delivery information by the second user; based on the existing delivery information of the second user, the first navigation information is obtained, and the first navigation information is sent to the mobile terminal of the second user.

Specifically, by installing detection units in the hydrogen storage exchange cabinets, the number of remaining full bottles of hydrogen storage tanks in each exchange cabinet can be acquired and updated in real time. By making requirements on the exchange process of the hydrogen storage bottles, the detection unit can improve the determination of the number of hydrogen storage tanks belonging to the full bottle. Specifically, the exchange process includes the following steps: acquiring the second request information sent by the mobile terminal of the first user, The second request information is the request information for the mobile terminal to establish contact with the exchange cabinet; establish contact with the mobile terminal of the first user, and start the replacement procedure of the hydrogen storage device; when the first user is obtained to deliver the hydrogen storage device After emptying the bottle and taking the full bottle of hydrogen storage tank, count the number of full bottle hydrogen storage tanks in the exchange cabinet, and send the quantity information to the platform management system; or/and, obtain the second user's mobile terminal to send After obtaining the second request information from the second user, establish contact with the first terminal, and start the replacement procedure of the hydrogen storage tank; after obtaining the second user's replenishment and replacement operation behavior, the number of full bottles of hydrogen storage tanks in the exchange cabinet is obtained. Make statistics and send the quantity information to the platform management system.

In other words, after the exchange cabinet establishes contact with the mobile terminal of the first user, the operation process of the first user is bound with the identity information of the first user, and is transmitted to the platform management system; The user's operation process is to deliver the empty hydrogen storage bottle first, and then eject the full hydrogen storage bottle from the exchange cabinet. After the exchange cabinet establishes contact with the mobile terminal of the second user, the operation process of the second user is bound with the identity information of the second user, and is transmitted to the platform management system; The operation process includes: opening the exchange cabinet warehouse, adding a full bottle of hydrogen storage device, and taking out the empty bottle hydrogen storage device; or, taking out the empty bottle hydrogen storage device. Since the above-mentioned exchange process strictly follows the rule of "return first and then withdraw, return one and take one", it is possible to have a relatively accurate statistics on the number of remaining full-bottle hydrogen storage tanks in the exchange cabinet.

Wherein, the first user can be the user, volunteer or operation staff of the shared hydrogen fuel electric vehicle, to realize the replacement of the hydrogen storage device of the shared hydrogen fuel electric vehicle; the second user is the distribution of the hydrogen storage device Operators, mainly to supplement the full bottle of hydrogen storage in the exchange cabinet.

The priority level is the urgency that the exchange cabinet needs to distribute the full bottle of hydrogen storage tank. Generally speaking, the priority level is related to the number of the remaining full bottle of hydrogen storage tank in the exchange cabinet. However, in this embodiment, the priority level is The level is also related to the passenger flow of the area, specifically, the priority level is positively related to the passenger flow of the area served by the switching cabinet within a predetermined period of time. In this embodiment, the priority levels are divided into three levels, and each level corresponds to a different weight, which is convenient for delivery operators to make more intuitive and quick judgments. The priority level judges the consumption of hydrogen storage tanks according to the flow of people around the exchange cabinet, and divides the priority level of the hydrogen storage tank that needs to be distributed in the exchange cabinet according to this, so as to meet the needs of users for hydrogen storage bottles in special areas and special time periods. . For example, a large gathering is held in a certain area during a certain period of time, which will inevitably lead to a greater demand for the number of hydrogen storage tanks in this area. Therefore, this area has a relatively high priority. Among them, the passenger flow can be obtained by connecting with the highway traffic system to obtain the vehicle flow of the main roads in the region, especially the number of hydrogen fuel electric vehicles.

The first threshold is an elastic floating value, and the size of the first threshold is related to the area where the exchange cabinet is located, the time period, the consumption speed of the hydrogen storage device in the exchange cabinet, the distribution capacity of the second user, and other factors. . For those skilled in the art, reasonable adjustments can be made according to the actual situation.

After the delivery information is generated, since the second user is generally performing other delivery tasks, it is necessary to determine that the second user is suitable for delivery according to the location information of the second user and the existing delivery information. Specifically, the screening method for the second user includes the following steps: determining the second user based on the current location information of the second user, information on the quantity of the remaining full-bottle hydrogen storage tanks in the second user, and existing delivery information the serviceable range; determine whether the position of the exchange cabinet in the newly added distribution information is within the serviceable range of the second user; if so, push the first request information to all the second users who meet the preset conditions; Whether the first feedback information from the second user is received in A mobile terminal of a second user in the vicinity of the station.

The first navigation information is the best route to the plurality of switching cabinets. However, due to the relatively high priority of some delivery information, it needs to be delivered quickly. Therefore, it is necessary to improve the existing navigation path. Specifically, the method for determining the first navigation information includes the following steps: obtaining the delivery information of the second user. the priority level, the navigation distance between the exchange cabinet and the second user, and the time used; assign values to the priority level, navigation distance and time used, and calculate the weighted average; sort the weighted average to obtain the order of execution of the delivery information sequence; based on the sequence and the location information of the switching cabinet, perform path planning through LBS (Location Based Services, location-based services) to obtain the first navigation information. In general, when the priority levels are the same or similar, the fluctuation range of the priority level assignment is small, and the impact on the order of delivery is small. When the demand for hydrogen storage in some special areas is relatively large, the priority level assignment is relatively If it is higher, it will have a greater impact on the order of distribution, which can meet the needs of users in special areas for hydrogen storage, and improve user experience.

In a further embodiment, the method for determining the serviceable range of the second user includes the following steps: acquiring the position information of the second user and the position information of the hydrogen storage device in the existing distribution information; The position information is the starting point, the position information of the hydrogen storage device in the existing distribution information is used as the end point, and multiple vectors are generated; the two first vectors and the second vector with the largest included angle among the multiple vectors are determined, and the third vector with the largest modulus length is determined. ; Taking the position of the second user as the origin, the first vector and the second vector as the boundary, and the modulus length of the third vector as the radius, a sector-shaped area is generated. The area covered by the above-mentioned fan-shaped area is the current serviceable range of the second user, but in the actual implementation process, the serviceable range needs to be extended within the range of the fan-shaped area by a predetermined distance. The distance needs to be determined based on the number of delivery operators and delivery capacity.

In this embodiment, the service range of the operator can be reasonably designed according to the existing distribution information of the operator, and the serviceable range of the operator can be updated in real time, so as to avoid wasting time by the operator due to multiple detours, thereby improving the distribution efficiency of the hydrogen storage device.

In a further embodiment, the second user replaces the hydrogen storage bottle in the exchange cabinet, and then the second user transports the empty bottle hydrogen storage tank to the hydrogen refueling station for hydrogen filling of the hydrogen storage tank; in this implementation In the example, the second user scans the QR code information of the hydrogen storage tank, moves the second request information sent to the platform management system, establishes a connection with the exchange cabinet, and starts to execute the replacement procedure of the hydrogen storage tank; If the second user has sufficient hydrogen storage tanks, add a full hydrogen storage tank, and remove the empty hydrogen storage tank. The platform management system re-issues the information to the distribution operators. At the same time, the number of full-bottle hydrogen storage tanks in the exchange cabinet is counted, and the information on the number of full-bottle hydrogen storage tanks is sent to the platform management system.
