Description

Technical Field

[0001] The present invention relates to the field of warehousing and logistics technology, and in particular to a supply chain financial inspection method and system based on virtual reality. Background Art

[0002] The existing supply chain finance inspection methods are roughly as follows:

[0003] Manual supervision: Funding party supervisors conduct spot checks, verifications and valuations on supply chain finance target assets (such as inventory, goods, equipment, etc.) through inspections and visits.

[0004] System inspection (SAAS service): SAAS service is provided by a third-party regulatory agency system. The funding party can view the quantity, validity period, value, storage location, real-time video, data indicators, warning threshold settings, etc. of the underlying assets in real time through the client.

[0005] System inspection (system connection): The funding party’s own system is connected to the third-party regulatory agency system. The third-party regulatory agency system transmits data such as the quantity, validity period, and value of the underlying assets. The funding party conducts data governance, modeling, and sets indicators based on its own risk control preferences.

[0006] However, the existing supply chain finance inspection methods have the following disadvantages:

[0007] The manual inspection method requires supervisors to be present at the supervision site in person to check the detailed information of the target assets, and it is impossible to obtain key information of the target assets in real time. It is costly, cannot provide early warning, and has serious risk loopholes.

[0008] The system inspection (SAAS service and system docking) method can only query limited text description information of the target assets, and cannot perceive the status of the goods in real time through all-round images and videos, which has flaws in risk control. Summary of the invention

[0009] The purpose of the present invention is to provide a supply chain financial inspection method and system based on virtual reality, which can monitor the actual situation and asset details of financial target assets in real time, allowing risk control personnel to observe the overall picture of core target assets in an immersive way. The monitoring effect is close to that of manual inspection, the frequency and convenience of inspection are greatly improved, and the cost of manual supervision is reduced.

[0010] To achieve the purpose of the present invention, the present invention adopts the following technical solutions:

[0011] The first aspect of the present invention proposes a supply chain finance inspection method based on virtual reality.

[0012] The inspection method comprises the following steps:

[0013] Establishing an electronic fence around the target asset;

[0014] Issue inspection control instructions to the inspection robot through VR head display and operating equipment;

[0015] The inspection robot operates according to the inspection control instructions and feeds back the asset information of the target asset to the VR head display and the operating device in real time;

[0016] Wherein, the electronic fence is used to limit the inspection area of ​​the inspection robot.

[0017] A further improvement is that before establishing an electronic fence for the target asset, the following steps are also included:

[0018] The financial regulatory system issues regulatory instructions to the financial regulatory warehouse system;

[0019] The financial regulatory warehouse system authenticates regulatory instructions;

[0020] If the authentication fails, the authentication failure information is returned. If the authentication succeeds, the steps of establishing an electronic fence for the target asset are initiated.

[0021] A further improvement is that after establishing an electronic fence for the target asset, it also includes:

[0022] The financial supervision warehouse system calculates the optimal path from the inspection robot to the electronic fence, configures inspection information for the inspection robot, and feeds back the information to the financial supervision system after the configuration is completed.

[0023] A further improvement is that before issuing inspection control instructions to the inspection robot through the VR headset and the operating device, the following steps are also included:

[0024] The financial supervision system issues an inspection demand instruction to the financial supervision warehouse system;

[0025] The financial supervision warehouse system receives the inspection demand instruction and performs authentication. If the authentication fails, it returns authentication failure information. If the authentication succeeds, it opens the electronic fence and returns authentication success information;

[0026] The inspection robot reaches the electronic fence area of ​​the target asset along the optimal path.

[0027] A further improvement is that the authentication includes at least one of the following two operation modes:

[0028] User account and password verification;

[0029] Compare pupil and facial feature data.

[0030] A further improvement is that the method for establishing an electronic fence for the target asset includes:

[0031] The target asset is retrieved and associated with the 3D map of the financial regulatory warehouse to obtain a coordinate set of the target asset's location, which is the electronic fence of the target asset. The visual range of the inspection robot must not exceed the electronic fence.

[0032] A further improvement is that when the inspection robot is within the range of the electronic fence, the viewing angle of the inspection robot is calculated in real time as the coordinates of the inspection robot change, wherein the range of the robot's vertical viewing angle θ is: -θ2≤θ≤θ1, wherein cosθ1=d1 / d2, cosθ2=d1 / d3, d1 is the straight-line distance between the inspection robot and the target asset, d2 is the distance between the inspection robot and the upper boundary of the electronic fence, and d3 is the distance between the inspection robot and the lower boundary of the electronic fence.

[0033] A further improvement is that the inspection control instructions include one or more of forward, backward, rotation, head up and head down, and the asset information includes video status of the target assets, and the asset details are displayed in real time through video. The asset details include one or more of product name, shelf life, quantity, production date, warehousing date, batch number, registered price and early warning information.

[0034] The second aspect of the present invention proposes a supply chain financial inspection system based on virtual reality, which is executed using a supply chain financial inspection method based on virtual reality as described in any one of the first aspects. The inspection system includes a financial supervision system, a financial supervision warehouse system, an inspection robot, a VR headset and an operating device.

[0035] A further improvement is that the inspection robot is equipped with an electromagnetic wave tracker, an optical tracker, and a high-definition camera.

[0036] Beneficial effects of the present invention:

[0037] The present invention can monitor the actual situation and asset details of financial target assets in real time. Through VR headsets and operating devices, target asset risk control personnel can observe the overall picture of core target assets in an immersive way. The inspection scope and granularity can also be customized. The monitoring effect is close to that of manual inspection methods, and the inspection frequency is more flexible and convenient, which reduces the cost of manual supervision.

In addition, in the description of the present application specification and the attached claims, the terms "first", "second", "third" etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0049] References to "one embodiment" or "some embodiments" etc. described in the specification of this application mean that one or more embodiments of the present application include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0050] Please refer to the attached Figure 1 -Attached Figure 6 In a first aspect, an embodiment of the present invention proposes a supply chain finance inspection method based on virtual reality, such as Figure 1 As shown, the inspection method comprises the following steps:

[0051] Step S10: The financial regulatory warehouse system establishes an electronic fence for the underlying assets;

[0052] Step S20: The risk control personnel of the funding party issue inspection control instructions to the inspection robot through the VR headset and operating equipment;

[0053] Step S30: the inspection robot operates according to the inspection control instruction and feeds back the asset information of the target asset to the VR head display and the operating device in real time;

[0054] Wherein, the electronic fence is used to limit the inspection area of ​​the inspection robot.

[0055] It should be noted that the risk control personnel of the funding party are inspection personnel dispatched by the funding party to which the index assets belong. The VR headset and operating equipment include a VR stereo display device and an operating equipment. After wearing the VR stereo display device, the risk control personnel of the funding party can view the asset information of the feedback target assets, and can issue inspection control instructions to the inspection robot through the operating equipment.

[0056] In addition, the target assets and the inspection robot are both located in the financial supervision warehouse. The financial supervision warehouse refers to a warehouse used to store target assets. The target assets of multiple customers can be placed in the financial supervision warehouse at the same time. Under the limitation of the electronic fence, the capital risk control personnel can only control the inspection robot to supervise the target assets to which they belong, but cannot view the assets of other customers. When the inspection control instructions of the inspection robot controlled by the capital party's risk control personnel exceed the visual range limited by the electronic fence, an error message will be returned and an alarm will be issued to remind the capital party's risk control personnel that the operation has exceeded the range limited by the electronic fence, thereby ensuring the asset security and privacy of other customers in the financial supervision warehouse.

[0057] Further, such as Figure 2 As shown, in this embodiment, before establishing an electronic fence for the target asset, the following steps are also included:

[0058] Step S00: The regulator issues a supervision instruction to the financial supervision warehouse system through the financial supervision system;

[0059] Step S01: The financial supervision warehouse system authenticates the supervision instruction;

[0060] If the authentication fails, the authentication failure information is returned. If the authentication succeeds, the steps of establishing an electronic fence for the target asset are initiated.

[0061] It should be noted that the regulator refers to the manager of the entire financial regulatory warehouse, and it has the right to issue regulatory instructions for different assets within the entire financial regulatory warehouse. Specifically, the regulatory instructions contain information such as the target customer and asset details. The financial regulatory warehouse system performs necessary authentication on the regulatory instructions issued by the regulator. If the authentication fails, it returns the authentication failure information to the financial regulatory system, indicating that the regulatory instruction is wrong. If the authentication is successful, it starts the step of establishing an electronic fence for the target asset, and establishes an electronic fence for the target asset to prepare for the subsequent inspection by the risk control personnel of the funding party.

[0062] In addition, the authentication may include at least one of the following two operation modes:

[0063] The first method is user account and password verification; that is, verifying whether the user account and password entered by the supervisor administrator are correct. If the account exists and the password is correct, the verification is successful.

[0064] The second method is to compare pupil and facial feature data, that is, to verify whether the pupil and facial feature data of the supervisor administrator matches the pre-entered pupil and facial feature data. If they match, the verification is passed.

[0065] In actual operation, you can use one of the authentication methods, or you can use a combination of the two authentication methods. Using a combination of the two authentication methods is safer.

[0066] Further, such as Figure 3 As shown, in this embodiment, after establishing an electronic fence for the target asset, the following steps are also included:

[0067] Step S11: the financial supervision warehouse system calculates the optimal path from the inspection robot to the electronic fence;

[0068] Step S12: configure inspection information for the inspection robot, and feed back the information to the financial regulatory system after the configuration is completed.

[0069] It should be noted that the financial regulatory warehouse system calculates a set of multiple paths for the inspection robot to get from a fixed location to the electronic fence area of ​​the target asset, and selects the optimal path from the multiple path sets. Factors considered for the optimal path may be that the path from the fixed location to the electronic fence area of ​​the target asset is the shortest, fastest, and has the fewest obstacles.

[0070] The inspection information configured for the inspection robot may specifically include the inspection requester, the target asset electronic fence, the inspection time range, the optimal path and other information. In this way, the inspection robot is configured after obtaining this information. After the configuration is completed, the configuration completion information is fed back to the financial regulatory system. After the financial regulatory warehouse receives the feedback configuration completion information, the subsequent steps can be initiated.

[0071] Further, such as Figure 3 As shown, in this embodiment, before the risk control personnel of the funding party issue the inspection control instruction to the inspection robot through the VR head display and the operating device, the following steps are also included:

[0072] Step S13: The risk control personnel of the funding party sends an inspection demand instruction to the financial supervision warehouse system through the financial supervision system;

[0073] Step S14: The financial supervision warehouse system receives the inspection demand instruction and performs authentication. If the authentication fails, the authentication failure information is returned. If the authentication succeeds, the electronic fence is opened and the authentication success information is returned and step S15 is executed;

[0074] Step S15: The inspection robot arrives at the electronic fence area of ​​the target asset along the optimal path. During this period, the inspection robot does not send back video information.

[0075] It should be noted that the command message of the inspection demand instruction includes identity information, demand information (inspection target assets, inspection duration, information display granularity), etc. After receiving the inspection demand instruction, the financial supervision warehouse system performs necessary authentication, which may include at least one of the following two operation modes:

[0076] The first method is user account and password verification; that is, verifying whether the user account and password entered by the risk control personnel of the funding party are correct. If the account exists and the password is correct, the verification is successful.

[0077] The second method is to compare pupil and facial feature data. That is, to verify whether the pupil and facial feature data of the funder's risk control personnel match the pre-entered pupil and facial feature data. If they match, the verification is passed.

[0078] In actual operation, you can use one of the authentication methods, or you can use a combination of the two authentication methods. Using a combination of the two authentication methods is safer.

[0079] If the authentication is passed, the electronic fence of the target asset can be activated. After activation, the risk control personnel of the funding party can proceed with the subsequent steps of issuing inspection control instructions.

[0080] Furthermore, in this embodiment, if Figure 5 As shown, the method for establishing an electronic fence for the target asset in step S10 includes:

[0081] The financial regulatory warehouse system retrieves the target assets and associates them with the 3D map of the financial regulatory warehouse to obtain a coordinate set (X, Y, Z) of the target asset's location, where X represents the horizontal coordinate and X>0, Y represents the vertical coordinate and Y>0, and Z represents the vertical coordinate and Z>0. The coordinate set (X, Y, Z) is the electronic fence (rectangle) of the target asset.

[0082] In addition, the financial regulatory warehouse system calculates the set of paths from the inspection robot to the fixed location (a, b, c) to the electronic fence area of ​​the target asset, and selects the optimal path from the inspection robot to the coordinate set of the target asset.

[0083] Among them, the visual range of the inspection robot shall not exceed the electronic fence.

[0084] It should be noted that the visual range of the inspection robot must not exceed the electronic fence, which means that the visual range of the inspection robot must not exceed the left boundary, right boundary, upper boundary and lower boundary of the electronic fence.

[0085] Specifically, in this embodiment, Figure 6As shown, when the inspection robot is within the range of the electronic fence, it is assumed that the inspection robot is at the electronic fence position coordinates (x', y', z'), where (x', y', z') ∈ (X, Y, Z). As the coordinates of the inspection robot change, the viewing angle of the inspection robot is calculated in real time, where the range of the robot's vertical viewing angle θ is: -θ2≤θ≤θ1, where cosθ1=d1 / d2, cosθ2=d1 / d3, d1 is the straight-line distance between the inspection robot and the target asset, d2 is the distance between the inspection robot and the upper boundary of the electronic fence, and d3 is the distance between the inspection robot and the lower boundary of the electronic fence.

[0086] Similarly, the range of the inspection robot's horizontal viewing angle β can be calculated based on the above method for calculating the range of the inspection robot's vertical viewing angle θ. As the inspection robot's coordinates change, the financial supervision warehouse system calculates the inspection robot's vertical viewing angle θ and horizontal viewing angle β in real time.

[0087] In this embodiment, the inspection control instructions in step S20 include one or more of forward, backward, rotation, head-up, and head-down. The forward and backward instructions can be used to conveniently adjust the coordinate position of the inspection robot, and the rotation, head-up, and head-down instructions can be used to conveniently adjust the viewing angle of the inspection robot, so that the target asset can be inspected in an all-round manner.

[0088] The asset information includes video information of the target assets, which displays the asset details in real time through video. The asset details include one or more of product name, shelf life, quantity, production date, warehousing date, batch number, registered price and early warning information.

[0089] For example, when the remaining shelf life of the underlying asset is less than 50%, this will be clearly displayed in the asset details.

[0090] Finally, when the risk control personnel of the funding party issues an inspection end instruction or the inspection time expires, the inspection ends and the inspection robot returns to the starting position along the original route.

[0091] The beneficial effects of this embodiment: the present invention can monitor the actual situation and asset details of financial target assets in real time. Through VR head displays and operating devices, the target asset risk control personnel can observe the overall picture of the core target assets in an immersive way. The inspection scope and granularity can also be customized. The monitoring effect is close to the manual inspection method, and the inspection frequency is flexible and convenient, which reduces the cost of manual supervision.

[0092] A second aspect of an embodiment of the present invention proposes a supply chain financial inspection system based on virtual reality, which is executed using a supply chain financial inspection method based on virtual reality as described in any one of the embodiments of the first aspect, and the inspection system includes a financial regulatory system, a financial regulatory warehouse system, an inspection robot, a VR headset and an operating device.

[0093] As an example but not limitation, corresponding to a supply chain finance inspection method based on virtual reality provided in the above-mentioned embodiment of the first aspect of the present invention, since a supply chain finance inspection system based on virtual reality provided in the embodiment of the present invention corresponds to a supply chain finance inspection method based on virtual reality provided in the above-mentioned embodiment of the first aspect of the present invention, the implementation method of the aforementioned supply chain finance inspection method based on virtual reality is also applicable to a supply chain finance inspection system based on virtual reality provided in this embodiment, and will not be described in detail in this embodiment.

[0094] In addition, the VR headset and operating device communicate with the inspection robot via 5G signals.

[0095] In this embodiment, the inspection robot is equipped with an electromagnetic wave tracker, an optical tracker, and a high-definition camera.

[0096] Among them, high-definition cameras are used to monitor and record the target assets. The principle of the electromagnetic wave tracker is to use a signal generator (3 orthogonal coil groups) to generate a low-frequency electromagnetic field, which is then received by another three orthogonal coil groups placed in the receiver. The position and direction of the tracked object are calculated by obtaining 9 data of induced current and magnetic field strength.

[0097] The principle of optical trackers is to use natural light, laser or infrared as the light source, but to avoid interfering with the user's line of sight, infrared is currently used. The movement of objects or people is recorded by measuring and receiving reflected light.

[0098] Those of ordinary skill in the art will appreciate that the units and algorithm steps of each example described in conjunction with the embodiments disclosed herein can be implemented in electronic hardware, or a combination of computer software and electronic hardware. Whether these functions are performed in hardware or software depends on the specific application and design constraints of the technical solution.
