[0050] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0051] In order to better understand the technical solutions of the present application, the following will be described in detail in combination with the accompanying drawings of the specification and specific embodiments.

[0052] The first embodiment of the park navigation system proposed by the present application is described with reference to Figure 1 , the park navigation system includes: a navigation planning device 10 and a navigation device 20, and the navigation device 20 is placed on a logistics vehicle in the park;

[0053] The navigation planning device 10 includes a first Lora module 11, a Routing module 12 and an information recognition module 13;

[0054] The navigation device 20 includes a second Lora module 21 and a Planning module 22;

[0055] The first Lora module 11 is wirelessly connected to the second Lora module 21, the Routing module 12 is respectively connected to the first Lora module 11 and the information recognition module 13, and the second Lora module 21 is also connected to the Planning module 22;

[0056] The information recognition module 13 is configured to recognize the task information transmitted externally and transmit the task information to the Routing module 12;

[0057] The Routing module 12 is configured to wirelessly transmit the corresponding path planning information to the second Lora module 21 through the first Lora module 11 when receiving the task information;

[0058] The Planning module 22 is configured to obtain the first target navigation path of the logistics vehicle and the corresponding safe driving trajectory when receiving the path planning information through the second Lora module 21.

[0059] It should be understood that both the first LoRa module 11 and the second LoRa module 21 are communication modules using LoRa technology, which can achieve long-distance, low-power, and anti-interference long-distance communication by expanding the signal spectrum bandwidth. A wireless connection relationship can be established between the first LoRa module 11 and the second LoRa module 21 through the LoRaWAN protocol, so that long-distance and efficient communication can be carried out between the first LoRa module 11 and the second LoRa module 21, and further information interaction can be carried out between the Routing module 12 connected to the first LoRa module 11 and the Planning module 22 connected to the second LoRa module 21.

[0060] It is worth noting that in this embodiment, the navigation device 20 and the navigation planning device 10 are mainly applied to the navigation of logistics vehicles in the park. The navigation planning device 10 can be fixed at the first intersection after entering the park, and this intersection can lead to various areas of the park; the navigation device 20 can move and is generally placed on the corresponding logistics vehicle during operation to provide navigation services for the logistics vehicle.

[0061] It should be noted that in this embodiment, the Routing module 12 refers to a functional module with the ability to plan the driving path. It stores high-precision map information of the park internally and can, based on the task information transmitted externally, obtain the starting point and ending point required for a logistics vehicle (not shown in the figure) assigned to the corresponding navigation device 20 to perform tasks. And based on the high-precision map information of the park, after planning the optimal path between the starting point and the ending point, it transmits the path planning information corresponding to the optimal path to the first LoRa module 11. The Planning module 22 refers to a functional module with the ability to plan the driving trajectory. It has functions such as positioning, sensing, and prediction. It can be used to locate the specific position where the current navigation device 20 is located to obtain the corresponding position information, and can also sense whether there are obstacles for the current navigation device 20 to obtain the corresponding obstacle information. And based on the received path planning information, the obtained position information, and the obstacle information, it predicts the current optimal driving trajectory.

[0062] It is easy to understand that the task information is the relevant information of the current task that the logistics vehicle in the park needs to execute. The tasks executed by the logistics vehicle are mainly to transport a certain specific object to a designated area. Therefore, the task information may include relevant geographical coordinate information such as the destination of the logistics vehicle. In specific implementation, the information recognition module 13 in the navigation planning device 10 can obtain externally transmitted task information in some specific cases. For example, first obtain the task work order number of the current task executed by the transport vehicle by identifying the work card of the staff, and then perform an internal table lookup to obtain the task information corresponding to the work order number. The Routing module 12 can, based on the obtained task information, obtain the specific coordinates of the destination of the logistics vehicle that needs to execute the corresponding task, and generate the optimal path planning information for reaching the destination according to the high-level map information stored internally. The Routing module 12 first transmits the path planning information to the first Lora module 11, and performs wireless transmission with the second Lora module 21 through the first Lora module 11, and finally transmits it to the Planning module 22 located on the logistics vehicle. The Planning module 22 can, based on the received path planning information, obtain the optimal first target navigation path for the current logistics vehicle to drive to the destination, and predict the corresponding safe driving trajectory on the first target navigation path in combination with the position information and obstacle information obtained by itself, so as to perform high-precision navigation for the logistics vehicle in the park, so that the driver of the logistics vehicle can drive the logistics vehicle to reach the destination in the park with the highest efficiency based on the provided first target navigation path and safe driving trajectory.

[0063] It should be noted that, in this embodiment, the logistics vehicle can also interact with the navigation device 20, that is, the Planning module 22 in the navigation device 20 can also be connected to the controller of the logistics vehicle (not shown in the figure), and can directly transmit the first target navigation path and the safe driving trajectory to the controller of the logistics vehicle, so that the controller can automatically control the logistics vehicle to drive along the first target navigation path and quickly drive to the destination along the safe driving trajectory, making the logistics in the park more intelligent, which can not only improve the logistics efficiency, but also reduce the labor cost, and can also ensure the safety of logistics transportation.

[0064] The present application provides a park navigation system. The park navigation system includes a navigation planning device and a navigation device. The navigation device is placed on a logistics vehicle within the park. The navigation planning device includes a first Lora module, a Routing module, and an information recognition module. The navigation device includes a second Lora module and a Planning module. The first Lora module is wirelessly connected to the second Lora module. The Routing module is respectively connected to the first Lora module and the information recognition module. The second Lora module is also connected to the Planning module. The information recognition module is configured to recognize task information transmitted externally and transmit the task information to the Routing module. The Routing module is configured to, when receiving the task information, wirelessly transmit corresponding path planning information to the second Lora module through the first Lora module. The Planning module is configured to, when receiving the path planning information through the second Lora module, obtain a first target navigation path of the logistics vehicle and a corresponding safe driving trajectory. By using the first Lora module in the navigation planning device and the second Lora module in the navigation device to establish a wireless connection relationship between the Routing module and the Planning module, when the Routing module obtains task information through the information recognition module electrically connected thereto, it wirelessly transmits the path planning information to the Planning module, enabling the Planning module to obtain the first target navigation path of the current logistics vehicle and the corresponding safe driving trajectory through the path planning information, precisely navigating the logistics vehicle within the park, safely driving to the destination along the optimal path, and improving the transportation efficiency and safety of the logistics vehicle.

[0065] Based on the first embodiment of the park navigation system of the present application, in the second embodiment of the park navigation system of the present application, for the same or similar content as in the above-mentioned first embodiment, reference can be made to the above introduction and will not be elaborated hereinafter. On this basis, please refer to Figure 2 , the Planning module 22 is further configured to collect road condition information on the safe driving trajectory and wirelessly transmit the road condition information to the first Lora module 11 through the second Lora module 21;

[0066] The Routing module 12 is further configured to, when receiving the road condition information through the first Lora module 11, wirelessly transmit the corrected path planning information to the second Lora module 21 through the first Lora module 11;

[0067] The Planning module 22 is further configured to obtain the second target navigation path of the logistics vehicle and the corresponding safe driving trajectory when receiving the corrected path planning information through the second Lora module 21.

[0068] It should be noted that, in this embodiment, the sensing function of the Planning module 22 can also be used to collect the road conditions on the first navigation path and the corresponding safe driving trajectory in real time, and wirelessly transmit the road condition information to the Routing module 12 through the second Lora module 21 and the first Lora module 11. The road condition information includes the obstacle information described above. If the Routing module 12 determines that there is an obstacle blocking the way in front of the logistics vehicle where the current navigation device 20 is located based on the received road condition information, it can re-plan the path, correspondingly correct the previously generated path planning information, and wirelessly transmit the corrected path planning information to the Planning module 22 of the navigation device 20 through the first Lora module 11 and the second Lora module 21. The Planning module 22 can, based on the corrected path planning information, re-obtain another unobstructed second target navigation path of the logistics vehicle from the current position to the destination, and at the same time re-obtain the safe driving trajectory corresponding to the second target navigation path to navigate the logistics vehicle, so that the logistics vehicle can reach the destination as soon as possible when the current path cannot be normally traveled.

[0069] Furthermore, in this embodiment, the navigation planning device 10 further includes: a monitoring module 14 and a WiFi module 15;

[0070] The monitoring module 14 is respectively connected to the Routing module 12 and the WiFi module 15, and the WiFi module 15 is also wirelessly connected to the park management platform 30;

[0071] The Routing module 12 is further configured to send the real-time coordinate information of the navigation device 20 to the monitoring module 14 when receiving the road condition information;

[0072] The monitoring module 14 is configured to obtain the real-time coordinates of the navigation device 20 when receiving the real-time coordinate information, and when the real-time coordinates are not within the preset coordinate range, wirelessly transmit a first alarm signal to the park management platform 30 through the WiFi module 15, so that the park management platform 30 controls the park access gate to lock.

[0073] It should be noted that the WiFi module 15 can provide a wireless network and connect to the park management platform 30 through the wireless network. The park management platform 30 refers to the general control platform within the park, which can control some automated devices within the park to work, such as controlling the locking or unlocking of the park access control. In this embodiment, the road condition information fed back by the Planning module 22 to the Routing module 12 through the second Lora module 21 and the first Lora module 11 can also include the real-time coordinate information corresponding to the real-time coordinates of the navigation device 20. When the Routing module 12 receives the road condition information, it can also transmit the real-time coordinate information therein to the monitoring module 14. The monitoring module 14 can obtain the current real-time coordinates corresponding to the navigation device 20 through the real-time coordinate information, and when the real-time coordinates exceed the set preset coordinate range, it can determine that the current navigation device 20 is not being used for normal logistics transportation (i.e., for example, in the case of being illegally stolen). At this time, a first alarm signal can be generated and transmitted to the WiFi module 15. Since the WiFi module 15 is wirelessly connected to the park management platform 30, the first alarm signal can be wirelessly uploaded to the park management platform 30, so that the park management platform 30 can timely control each park access control to lock, in order to prevent the navigation device 20 from being carried out of the park. In addition, through the first Lora module 11, the second Lora module 21, and the WiFi module 15, a wireless communication relationship can also be established among the navigation device 20, the navigation planning device 10, and the park management platform 30, enabling the staff on the logistics vehicle, the staff near the navigation planning device 10, and the staff at the park management platform 30 to communicate with each other, simplifying the management work within the park.

[0074] It is worth noting that in this embodiment, the preset coordinate range can be the range mainly for logistics transportation within the park, which can be set in the central area of the park, that is, there is also a non-working area in the park, and the non-working area surrounds the working area for logistics transportation.

[0075] Furthermore, in this embodiment, the navigation planning device 10 further includes: a prompt module 16;

[0076] The prompt module 16 is connected to the monitoring module 14;

[0077] The monitoring module 14 is further configured to send a second alarm signal to the prompt module 16 when the real-time coordinates are not within the preset coordinate range;

[0078] The prompt module 16 is configured to prompt the staff within the park that the navigation device 20 is not within the preset coordinate range of the park when receiving the second alarm signal.

[0079] It should be noted that in this embodiment, when the monitoring module 14 detects that the real-time coordinates of the navigation device 20 are not within the preset coordinate range, a second alarm signal can also be sent to the prompt module 16 in the navigation planning device 10. The prompt module 16 can include a signal lamp or a player. When receiving the second alarm signal, it can prompt the staff near the navigation planning device 10 in the form of optical signals or sound signals that the navigation device 20 has moved outside the preset coordinate range in the park, and it is necessary to arrange staff to confirm the specific situation of the navigation device 20 as soon as possible to prevent theft.

[0080] Based on the first embodiment and / or the second embodiment of the present application, in the third embodiment of the present application, the same or similar content as that in the above-mentioned first embodiment and second embodiment can be referred to the above introduction and will not be repeated hereinafter. On this basis, please refer to Figure 3 the navigation planning device 10 further includes: a power management module 17 and a first wireless charging module 18;

[0081] the navigation device 20 further includes: a power module 23 and a second wireless charging module 24;

[0082] The power management module 17 is respectively connected to the first wireless charging module 18, the first Lora module 11, the Routing module 12, and the information recognition module 13, and is used to supply power to the first Lora module 11, the Routing module 12, and the information recognition module 13;

[0083] The power module 23 is respectively connected to the second wireless charging module 24, the second Lora module 21, and the Planning module 22, and is used to supply power to the second Lora module 21 and the Planning module 22;

[0084] When the first wireless charging module 18 and the second wireless charging module are within a preset distance, the power management module 17 is further used to wirelessly charge the power module 23 through the first wireless charging module 18 and the second wireless charging module 24.

[0085] It should be understood that Figure 3 the connection relationship regarding the power supply function between the power management module 17 and other functional modules in the navigation planning device 10 is not completely drawn in

[0086] It should be noted that in this embodiment, the navigation planning device 10 is equipped with a power management module 17, which can supply power to each functional module included in the navigation planning device 10. For example, it supplies power to functional modules such as the Routing module 12 described above. At the same time, the navigation device 20 is equipped with a power module 23, which can supply power to each functional module included in the navigation device 20. For example, it supplies power to functional modules such as the Planning module 22 described above. The navigation planning device 10 is fixed at a specific position, so the power management module 17 inside it can be directly connected to the mains power to replenish the electrical energy of the power management module 17 through the mains power at any time. However, the navigation device 20 is a movable device, and the electrical energy stored in the power module 23 will gradually be consumed during the movement and cannot be replenished in time. To improve the battery life of the navigation device 20, a first wireless charging module 18 can be provided in the navigation planning device 10, and a second wireless charging module 24 can be provided in the navigation device 20. When the navigation device 20 and the navigation planning device 10 are within a preset distance, the power management module 17 and the power module 23 are wirelessly connected through the first wireless charging module 18 and the second wireless charging module 24, so that the power management module 17 can wirelessly charge the power module 23 through the first wireless charging module 18 and the second wireless charging module 24.

[0087] Furthermore, the navigation planning device 10 further includes: a transceiver compartment and a transceiver module 19. The transceiver module 19 is disposed in the transceiver compartment, and the transceiver compartment is used for storing the navigation device 20;

[0088] The transceiver module 19 is electrically connected to the Routing module 12;

[0089] The Routing module 12 is further configured to send a distribution signal to the transceiver module 19 when receiving the task information;

[0090] The transceiver module 19 is configured to eject the navigation device 20 from the transceiver compartment when receiving the distribution signal.

[0091] It should be noted that in this embodiment, for the convenience of managing and protecting the navigation device 20, the unused navigation devices 20 can be uniformly placed in the transceiver compartment of the navigation planning device 10. A corresponding transceiver module 19 is provided in the transceiver compartment for realizing the transceiver function of controlling the navigation device 20. In a specific implementation, when the Routing module 12 receives task information, it can be considered that the navigation device 20 in the corresponding transceiver compartment needs to be used, and a distribution signal can be sent to the transceiver module 19 in the corresponding transceiver compartment. The transceiver module 19 that receives the distribution signal can eject the corresponding navigation device 20 from the transceiver compartment, so that the staff can carry and place the navigation device 20 on the corresponding logistics vehicle to provide navigation services for the corresponding logistics vehicle.

[0092] Furthermore, in this embodiment, the transceiver module 19 is also connected to the power management module 17, and the first wireless charging module 18 is at the preset distance from the transceiver compartment;

[0093] The power management module 17 is further configured to send a recovery signal to the transceiver module 19 when wirelessly charging the power module 23;

[0094] The transceiver module 19 is further configured to fix the navigation device 20 in the transceiver compartment when receiving the recovery signal.

[0095] It is easy to understand that in this embodiment, the transceiver compartment ( Figure 3 not shown) and the power management module 17 can be set within a preset distance. When the staff puts the used navigation device 20 back into the transceiver compartment, since the second wireless charging module 24 in the navigation device 20 coincides with the transceiver compartment, the distance between the second wireless charging module 24 and the first wireless charging module 18 is within the preset distance. At this time, the power management module 17 can wirelessly charge the power module 23 in the navigation device 20 stored in the transceiver compartment through the first wireless charging module 18 and the second wireless charging module 24. At this time, when the power management module 17 is wirelessly charging the power module 23, it can also send a corresponding recovery signal to the transceiver module 19 in the corresponding transceiver compartment. The transceiver module 19 can fix the navigation device 20 in the transceiver compartment when receiving the transceiver signal, preventing the navigation device 20 from being damaged due to random movement and collision, and at the same time enabling the navigation planning device 10 to stably charge the navigation device 20.

[0096] Furthermore, in this embodiment, the navigation planning device 10 further includes: a first display module 110;

[0097] The first display module 110 is connected to the power management module 17;

[0098] The power management module 17 is further configured to obtain the power signal transmitted by the power module 23 through the second wireless charging module 24 and the first wireless charging module 18 when wirelessly charging the power module 23, and transmit the corresponding power display signal to the first display module 110;

[0099] The first display module 110 is configured to display the remaining power of the navigation device 20 and the navigation device 20 stored in the transceiver compartment when receiving the power display signal.

[0100] It should be noted that in this embodiment, when the power management module 17 wirelessly charges the power module 23 in the corresponding navigation device through the first wireless charging module 18 and the second wireless charging module 24, it can also obtain relevant electrical parameters such as the current remaining power of the power module 23 through the handshake signal generated by the charging current transmitted by the second wireless charging module 24 and the first wireless charging module 18 (i.e., the process of obtaining the power signal). And it can transmit the corresponding power display signal to the first display module 110. The first display module 110 can, based on the received power display signal, display that there is a navigation device 20 in the transceiver compartment that is being wirelessly charged, and at the same time, it can also display the remaining power of the power module 23 in the navigation device 20, so as to facilitate the staff to judge whether the remaining power of the power module 23 in the corresponding navigation device 20 can maintain the navigation device 20 to provide subsequent navigation services.

[0101] Further, in this embodiment, the navigation device 20 further includes: a second display module 25;

[0102] The second display module 25 is connected to the Planning module 22;

[0103] The Planning module 22 is further configured to output a corresponding navigation display signal to the second display module 25 when obtaining the first target navigation path and selecting the corresponding safe driving trajectory;

[0104] The second display module 25 is configured to display the first target navigation path and the safe driving trajectory when receiving the navigation display signal.

[0105] It should be noted that in this embodiment, when the Planning module 22 obtains the target navigation path of the current logistics vehicle (including the first target navigation path, the second target navigation path, etc.) and the corresponding safe driving trajectory, it can also send a corresponding navigation display signal to the second display module 25 to display the current target navigation path and the safe driving trajectory to the staff on the logistics vehicle.

[0106] Further, in the present embodiment, the park navigation system includes a plurality of the navigation devices 20.
