[0033] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The enumerated embodiments are only used to explain the present invention and are not used to limit the scope of the present invention.

[0034] Reference Figure 1 This embodiment provides a sample vehicle usage management system, which includes a client, a terminal device, a server, and a marker. The client runs on the terminal device, and the terminal device and the server communicate with each other. In this embodiment, the terminal device includes a PC and a handheld device, and the handheld device can be a tablet computer, a smart phone, or other handheld devices.

[0035] The client is used to register the entry and exit of sample vehicles / samples, bind or unbind sample vehicles / samples with markers, upload verification information and handover information of sample vehicles / samples, and query specific information and flow records of sample vehicles / samples stored in the server. The specific information includes basic information, verification information and location information of the sample vehicles / samples.

[0036] In this embodiment, after the sample vehicle / sample enters the warehouse, the warehouse entry and exit management personnel allocate an idle marker for it. The sample vehicle / sample can only be bound to one marker after entering the warehouse and before leaving the warehouse.

[0037] In this embodiment, the verification information is the information obtained by the warehouse entry and exit management personnel after receiving the sample vehicle / sample and verifying it, including but not limited to the appearance information, internal structure information, status information, fault information, etc. of the sample vehicle / sample.

[0038] In this embodiment, the basic information of the sample vehicle / sample includes but is not limited to the name, quantity, color, identification code, the last handover person, the next handover person, etc.

[0039] In this embodiment, the handover information includes but is not limited to the handover time, the name of the handover object, the quantity of the handover object, the handover personnel information, etc.

[0040] The server is used to respond to the client's business requests, store the sample vehicle / sample entry and exit registration information, verification information and handover information uploaded by the client, automatically generate flow records based on the sample vehicle / sample entry and exit registration information, and store the location information uploaded by the marker.

[0041] The marker is set on the sample vehicle / sample, and stores unique identification information that can be read by the terminal device. The unique identification information is used to uniquely identify the marker. The marker is used to locate the position of the sample vehicle / sample and upload the position information to the server.

[0042] As an optional embodiment, the client specifically includes a login and logout module, a warehouse entry registration module, and a warehouse exit registration module.

[0043] The login and logout module is used for the user to log in to the system through preset login information, or to log out of the login status of the currently logged in account.

[0044] In this optional embodiment, the preset login information includes an account number and password, and may also include biometric information, such as fingerprints, facial images, etc.

[0045] The entry registration module is used to register the basic information of the sample vehicle / sample when it enters the warehouse, take an image of the sample vehicle / sample as entry verification information, read the unique identification information of the marker assigned to the sample vehicle / sample, bind it with the basic information of the sample vehicle / sample to generate binding information, and upload the basic information of the sample vehicle / sample, entry verification information and binding information to the server.

[0046] The outbound registration module is used to read the unique identification information of the marker assigned to the sample vehicle / sample when the sample vehicle / sample is outbound, query the basic information of the outbound sample vehicle / sample according to the unique identification information, generate unbinding information according to the basic information and unique identification information of the outbound sample vehicle / sample, register the handover information of the outbound sample vehicle / sample, take an image of the sample vehicle / sample as outbound verification information, and upload the unbinding information, outbound verification information, and handover information of the outbound sample vehicle / sample to the server.

[0047] In this optional embodiment, the warehouse entry and exit management personnel register the sample vehicles or samples through the warehouse entry registration module and the warehouse exit registration module respectively when the sample vehicles or samples enter or leave the warehouse, including the basic information of the sample vehicles or samples entering / leaving the warehouse, and take the image of the sample vehicles / samples as the warehouse entry verification information or the warehouse exit verification information, so as to trace whether the sample vehicles or samples have changed between entering and leaving the warehouse. When entering the warehouse, the warehouse entry and exit management personnel allocate the idle markers to the sample vehicles or samples, and bind them to the basic information of the sample vehicles or samples by reading the unique identification information stored in the marker. When leaving the warehouse, the warehouse entry and exit management personnel need to unbind the marker from the sample vehicles or samples.

[0048] On this basis, the client also includes a query module, which is used to read the unique identification information of the marker, and query the basic information and warehousing verification information of the sample vehicle / sample bound to it according to the unique identification information; or query the warehousing verification information, outbound verification information or handover information of the sample vehicle / sample according to the basic information of the sample vehicle / sample.

[0049] As another optional embodiment, the server specifically includes a processing module and an in-and-out storage database.

[0050] Among them, the processing module is used to receive the business request sent by the client, update the sample vehicle / sample entry and exit related data stored in the entry and exit database according to the business request content, or query the sample vehicle / sample entry and exit related data stored in the entry and exit database according to the business request content, and feedback the query results to the client that initiated the business request.

[0051] The in-and-out database is used to store and manage the in-and-out data related to the sample vehicle / sample, and the in-and-out data includes basic information of the sample vehicle / sample, entry verification information, exit verification information, handover information, binding information, unbinding information and location information.

[0052] On this basis, the server also includes a first analysis module and a second analysis module.

[0053] Among them, the first analysis module is used to input the entry verification information of the incoming sample vehicle / sample into the pre-trained damage analysis model for analysis when receiving the entry verification information, obtain the first damage information of the incoming sample vehicle / sample, and establish a binding relationship between the first damage information and the basic information of the corresponding sample vehicle / sample.

[0054] In this optional embodiment, the damage analysis model is a machine learning model that is pre-trained using labeled sample vehicle / sample images.

[0055] The second analysis module is used to, when receiving the outbound verification information of the outbound sample vehicle / sample, search for the first damage information bound to it according to the basic information of the outbound sample vehicle / sample, input the outbound verification information into the damage analysis model for analysis, obtain the second damage information of the outbound sample vehicle / sample, compare and analyze the first damage information bound to it with the second damage information, obtain the damage change information used to characterize the damage change of the sample vehicle / sample, and send the damage change information to the client.

[0056] This optional embodiment uses a damage analysis model to analyze the entry verification information and exit verification information when the sample vehicle / sample enters and leaves the warehouse to obtain the first damage information and the second damage information that characterize the damage status of the sample vehicle / sample when entering and leaving the warehouse. By comparing and analyzing the first damage information and the second damage information, it is determined whether the damage status of the sample vehicle or sample has changed during the entry period, such as whether there is new damage or whether the original damage has been amplified. When the damage status of the sample vehicle or sample changes, corresponding damage change information is generated and sent to the client, so that the entry and exit management personnel can confirm the reason for the change in the damage of the sample vehicle or sample.

[0057] As an optional embodiment, refer to Figure 2, the marker includes a housing 1, on which a storage medium 2 is arranged, and the storage medium 2 is used to store the unique identification information of the marker. A groove 3 is arranged at the bottom of the housing 1, and a sliding plate 4 is slidably arranged in the groove 3. An attachment portion 5 is arranged at the bottom of the sliding plate 4, and the attachment portion 5 is used to fix the marker on the surface of the sample vehicle / sample. A plurality of retractable sleeves 6 are arranged between the groove 3 and the sliding plate 4, one end of the retractable sleeves 6 is fixedly connected to the top of the groove 3, and the other end is fixedly connected to the top of the sliding plate 4. A first magnet 7 is also arranged at the top of the groove 3, and a pressure sensor 8 is fixedly arranged at the bottom of the first magnet 7. A second magnet 9 for cooperating with the first magnet 7 is arranged at the top of the sliding plate 4. A microprocessor, a positioning module and a communication module (not shown in the figure) are also arranged in the housing 1, and the pressure sensor, the positioning module and the communication module are respectively connected to the microprocessor signal, and the communication module is used to send data to the server.

[0058] In this optional embodiment, the storage medium 2 may be a QR code, or an NFC card, or an electronic tag, which is not specifically limited in this embodiment.

[0059] In this optional embodiment, the attachment portion 5 may be a suction cup or a sticky substance, which is not specifically limited in this embodiment.

[0060] In this optional embodiment, when the marker is fixed on the surface of the sample vehicle or sample, in the absence of external force, the first magnet 7 and the second magnet 9 will be attracted together due to magnetic effect. At this time, the pressure sensor 8 between the two will be subjected to pressure and generate a corresponding electrical signal and send it to the microprocessor. The microprocessor sends the electrical signal generated by the pressure sensor 8 to the server through the communication module. If someone removes the marker from the surface of the sample vehicle or sample, in the process of pulling the shell, since the adhesion between the attachment part 5 and the surface of the sample vehicle or sample is greater than the magnetic force between the first magnet 7 and the second magnet 9, the first magnet 7 and the second magnet 9 will separate first when the marker leaves the surface of the sample vehicle or sample. At this time, the pressure on the pressure sensor 8 will decrease, which will cause the electrical signal it generates to change. The server can determine whether the marker has been removed from the surface of the sample vehicle or sample based on the change in the pressure sensor signal.

[0061] Exemplarily, the pressure sensor 8 may be a piezoelectric film sensor, or other types of pressure sensors, which are not specifically limited in this embodiment.

[0062] On this basis, the server also includes a positioning module and an alarm module.

[0063] The positioning module is used to obtain the unique identification information and location information uploaded by each marker, query the sample vehicle / sample bound to the marker according to the unique identification information, and update the location of the sample vehicle / sample according to the location information. The warehouse management personnel or other users can query the latest location information of the sample vehicle or sample stored in the server through the client, so as to quickly locate the sample vehicle or sample.

[0064] The alarm module is used to obtain the pressure sensor signal uploaded by the marker communication module to monitor the pressure sensor signal, and determine whether the marker is removed based on the pressure sensor signal. When the marker is removed, it is determined whether the removal of the marker is normal based on whether the sample vehicle / sample bound to the marker has been released from the warehouse. If the marker is removed abnormally, an alarm message is generated, which includes the location information uploaded for the last time before the marker was removed abnormally.

[0065] This optional embodiment is implemented by providing a marker that can detect whether it has been removed. When the sample vehicle or sample corresponding to the marker has not been removed from the warehouse, if the server detects that the marker has been removed, an alarm will be promptly issued so that the staff can confirm the status of the corresponding sample vehicle or sample.

[0066] In some embodiments, an alarm is also provided in the shell 1, and the alarm is connected to the microprocessor through a control circuit, and is used to alarm when the marker is abnormally removed, so as to actively prompt surrounding people to check the situation when the marker is abnormally removed.

[0067] The abnormal removal means that the marker is removed from the surface of the sample vehicle or sample without being untied from the sample vehicle or sample to which it is bound. When the server detects that the marker has been removed, it queries whether it is bound to the sample vehicle or sample based on the unique identification information of the removed marker. If it is not found to be bound to the sample vehicle or sample, it indicates that the marker has been removed normally; if it is found to be bound to the sample vehicle or sample, it indicates that the marker has been removed abnormally. In other words, when the sample vehicle or sample is leaving the warehouse, the warehouse entry and exit management personnel first need to read the unique identification information of the marker on the sample vehicle or sample leaving the warehouse through the client to send an unbinding request to the server. After unbinding, the marker can be removed from the sample vehicle or sample leaving the warehouse to avoid triggering an alarm.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
