Description

Technical Field

[0001] This invention relates to the field of Internet of Things (IoT) technology, and specifically to a method and system for hierarchical management of goods based on rail transit. Background Technology

[0002] With the rapid development of automated systems due to technological advancements, corresponding access control models have also been rapidly developed to ensure the stable operation of these systems. Common scenarios, such as confidentiality and login scenarios, widely implement access control, which not only helps achieve security management but also improves work efficiency through clear division of responsibilities. Therefore, the hierarchical management achieved through access control has broad application prospects. Storage lockers, as a typical scenario involving the retrieval and placement of multiple items, require clearly defined access permissions. Only the person responsible for the item and the administrator can open the locker to ensure the security of the stored items. Currently, parcel lockers, serving as intermediate transfer facilities, typically have three-party permissions: the parcel delivery person, the parcel recipient, and the parcel locker manager. Different permissions correspond to different actions that can be performed on the parcel locker.

[0003] In rail transit systems, the secure storage and use of numerous and complex keys is a prerequisite for the safe operation of rail transit. The keys used in rail transit systems include: passenger car door keys, driver's cab door keys, electrical keys, tool cabinet keys, electrical cabinet keys, etc. On the one hand, the similar appearance of each key makes them easy to confuse; on the other hand, in order to ensure the safety of train operation, there are only one or two keys corresponding to each function. Therefore, it is necessary to keep track of the usage status of each key in a timely manner so that it can be managed and retrieved promptly when there is a temporary need, thereby reducing potential safety hazards.

[0004] While existing hierarchical management methods can achieve hierarchical management of items, they mostly fall under the category of temporary storage management of privately owned items. Hierarchical management of public items primarily involves usage rights, with higher-level permissions mainly for simple process operations such as approvals. Due to the special nature of rail transit systems, hierarchical management of keys involves not only simple key usage approvals but also timely retrieval based on the key's application scenarios. Therefore, there is currently a lack of a hierarchical key management method that can be specifically applied to rail transit systems. Summary of the Invention

[0005] The purpose of this invention is to provide a hierarchical management method and system for items based on rail transit. It adopts a permission-based approach to manage and track keys hierarchically, and utilizes the special environment of rail transit to quickly locate and hand over keys, thereby solving the problems of untimely key allocation and security risks in existing rail transit systems.

[0006] To achieve the above objectives, the present invention proposes the following technical solution: a method for hierarchical management of goods based on rail transit, comprising:

[0007] Determine the levels of item classification management and the corresponding management permissions for each level;

[0008] Upon receiving a first user request, determine whether the scope of the first user request falls within the management authority scope corresponding to the user level; wherein, the first user request includes items selected by the user to be used;

[0009] When it is determined that the scope of the first user's request exceeds the management authority scope corresponding to the user level, a first message is sent to the user; when it is determined that the scope of the first user's request falls within the management authority scope corresponding to the user level, the item location information corresponding to the first user's request is determined; wherein, the first message is used to prompt the first user that the request is out of scope.

[0010] Based on the item's location information, determine whether the item is stored in the item storage unit;

[0011] When at least one item corresponding to the first user's request is stored in the item storage unit, the item storage unit is opened to allow the item to be retrieved; when all items corresponding to the first user's request have been retrieved from the item storage unit, a second message is sent to the user; wherein, the second message contains multiple location information of the items corresponding to the first user's request.

[0012] Receive a second user request, which includes the user-selected item location information, required time information, and usage location information;

[0013] Based on the second user's request, generate multiple path strategies for obtaining items and provide feedback to the user.

[0014] Furthermore, it also includes:

[0015] Receive a request from a third user, the third user request being a reservation request form, the reservation request form including the item to be used and the reserved usage time;

[0016] Determine whether the item corresponding to the reservation request is available at the scheduled usage time;

[0017] When at least one item corresponding to the reservation request is available, the right to use at least one available item within the predetermined usage time range is locked, and a third message is sent to the user to indicate that the reservation was successful; when all items corresponding to the reservation request are available, a fourth message is sent to the user to indicate that the reservation failed.

[0018] Furthermore, it also includes:

[0019] Determine the priority of the first user's request;

[0020] When the priority of the first user's request is higher than the management authority and reaches the preset priority, the location information of the item corresponding to the first user's request is determined, and a fifth message is sent back to the user; wherein, the fifth message contains multiple location information corresponding to the item requested by the first user.

[0021] Furthermore, the specific process of generating multiple path strategies for obtaining items based on the second user's request and feeding them back to the user is as follows:

[0022] Based on rail transit operation information, obtain the traffic trajectory corresponding to the location information of the item selected by the user;

[0023] Based on the principles of shortest time and shortest path, all paths to obtain the item are calculated by traversing all stops along the traffic trajectory using demand time information and location information.

[0024] A sixth message containing all path information for obtaining the item is generated and sent back to the user.

[0025] Furthermore, it also includes:

[0026] Receive a fourth user request, which is used to query the trajectory of an item selected by the user;

[0027] Based on the management authority scope corresponding to the user level, determine the query area and query time range corresponding to the fourth user's request;

[0028] The feedback includes a seventh message sent to the user, showing the trajectory information of the selected item within the query area and time range.

[0029] Another technical solution of the present invention discloses a graded management system for goods based on rail transit, the system comprising:

[0030] The first determination module is used to determine the levels of item hierarchical management and the corresponding management permissions for each level;

[0031] The first receiving module is used to receive a first user request, wherein the first user request includes an item selected by the user to be used;

[0032] The first judgment module is used to determine whether the scope of the first user's request falls within the management authority scope corresponding to the user level; when it is determined that the scope of the first user's request exceeds the management authority scope corresponding to the user level, a first message is sent back to the user; when it is determined that the scope of the first user's request falls within the management authority scope corresponding to the user level, the item location information corresponding to the first user's request is determined; wherein, the first message is used to prompt the first user that the request is out of scope.

[0033] The second judgment module is used to determine whether an item is stored in the item storage unit based on the item location information; when at least one item corresponding to the first user's request is stored in the item storage unit, the module controls the opening of the item storage unit so that the item can be retrieved; when all items corresponding to the first user's request have been retrieved from the item storage unit, a second message is sent back to the user; wherein, the second message contains multiple location information of the items corresponding to the first user's request.

[0034] The second receiving module is used to receive a second user request, which includes the user-selected item location information, required time information, and usage location information.

[0035] The generation module is used to generate multiple path strategies for obtaining items based on the second user's request and then feed them back to the user.

[0036] Furthermore, it also includes:

[0037] The third receiving module is used to receive a third user request, which is a reservation application form, and the reservation application form includes the item to be used and the reserved usage time.

[0038] The third judgment module is used to determine whether the item corresponding to the reservation application is available during the scheduled usage time. When at least one item corresponding to the reservation application is available, the right to use at least one available item within the scheduled usage time is locked, and a third message is sent to the user to indicate that the reservation was successful. When all items corresponding to the reservation application are not available, a fourth message is sent to the user to indicate that the reservation failed.

[0039] Furthermore, it also includes:

[0040] The fourth judgment module is used to determine the priority of the first user's request;

[0041] The second determining module is used to determine the location information of the item corresponding to the first user's request when the priority of the first user's request is higher than the management authority and reaches a preset priority, and to send a fifth message back to the user; wherein the fifth message contains multiple location information corresponding to the item requested by the first user.

[0042] Furthermore, the generation module generates multiple path strategies for obtaining items based on the second user's request and feeds them back to the user's execution unit, including:

[0043] The acquisition unit is used to acquire the traffic trajectory corresponding to the location information of the item selected by the user, based on the rail transit operation information.

[0044] The calculation unit is used to calculate all paths to obtain items by traversing all stops on the traffic trajectory based on the principles of shortest time and shortest path, using demand time information and location information respectively.

[0045] A feedback generation unit is used to generate a sixth message containing all path information for obtaining the item, which is then sent back to the user.

[0046] The present invention also proposes an electronic device, which includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor runs the computer program, it implements the above-described method for hierarchical management of goods based on rail transit.

[0047] As can be seen from the above technical solutions, the technical solutions of the present invention have achieved the following beneficial effects:

[0048] This invention discloses a hierarchical management method and system for items based on rail transit. The method includes: determining the hierarchical management levels of items and the corresponding management permissions for each level; receiving a first user request and determining whether the scope of the first user request falls within the management permission range corresponding to the user level; if the request exceeds the management permission range corresponding to the user level, issuing a feedback indicating an overstepping of the request; if the request falls within the management permission range, determining the corresponding item location information; based on the item location information, determining whether the item is stored in an item storage unit; if at least one item is stored in the item storage unit, controlling the opening of the item storage unit; when all items are retrieved from the item storage unit, issuing a second message containing multiple location information of the items; receiving a second user request; and based on the second user request, generating multiple path strategies for obtaining the items and sending them back to the user. This invention, through hierarchical management of items, fully ensures that item keys can only be accessed by multiple authorized users and achieves timely allocation by obtaining the item location information.

[0049] When applied to rail transit systems, this invention promotes standardized key retrieval by setting access permissions for keys, ensuring the security of key storage and use. Simultaneously, by prioritizing user requests, it enables temporary key allocation, significantly improving key efficiency compared to existing technologies that lack control over key usage, thus helping to resolve emergencies. Furthermore, it allows for key tracking, preventing key loss and confusion.

[0050] Therefore, this technical solution comprehensively considers various aspects and solves the problems of easy confusion when handling similar items and low efficiency in allocation and retrieval. It thus meets the management needs for handling multiple items, especially in scenarios like rail transit.

[0051] It should be understood that all combinations of the foregoing concepts and the additional concepts described in more detail below can be considered part of the inventive subject matter of this disclosure, provided that such concepts do not contradict each other.

[0052] The foregoing and other aspects, embodiments, and features of the teachings of the present invention will be more fully understood from the following description in conjunction with the accompanying drawings. Other additional aspects of the invention, such as features and / or beneficial effects of exemplary embodiments, will become apparent from the following description or may be learned through practice of specific embodiments according to the teachings of the present invention.

[0059] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention. Unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by those skilled in the art to which this invention pertains.

[0060] The terms "first," "second," and similar words used in the specification and claims of this patent application do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Similarly, unless the context clearly indicates otherwise, the singular forms of "an," "a," or "the," etc., do not indicate a quantity limitation, but rather indicate the presence of at least one. Terms such as "comprising" or "including" mean that the element or object preceding "comprising" encompasses the features, integrals, steps, operations, elements, and / or components listed following "comprising" or "including," and do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or collections thereof. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0061] While existing technologies offer methods for managing multiple items, they often fail to consider the unique challenges of handling multiple items, particularly in scenarios like rail transit. This lack of consideration prevents key confusion during retrieval and hinders efficient allocation and tracking of items. Consequently, these methods are unsuitable for managing multiple items. Therefore, this embodiment aims to provide a management method applicable to the handling of multiple items in such scenarios.

[0062] Existing hierarchical management methods primarily involve three-party hierarchical management of owned items / tasks, while hierarchical management of public goods mainly focuses on usage rights management, with higher-level permissions primarily for simple process operations such as approval. Due to the unique nature of rail transit systems, these hierarchical management methods, while capable of approving the use of keys within the rail transit system, cannot further meet the application needs of temporary key access and trajectory tracking. Therefore, this invention aims to propose a hierarchical management method and system for items based on rail transit systems. By setting hierarchical management permissions for items, users are required to strictly adhere to their authorized scope when using them, while keys can be promptly allocated upon user requests. This not only ensures the security of key access but also improves the efficiency of key usage.

[0063] The following, in conjunction with the accompanying drawings, provides a further detailed description of the graded management method and system for rail transit-based goods disclosed in this embodiment.

[0064] Combination Figure 1 As shown in the figure, the item classification management method based on rail transit disclosed in this invention includes the following steps:

[0065] Step S102: Determine the levels of item hierarchical management and the corresponding management permissions for each level;

[0066] Step S104: Receive a first user request and determine whether the scope of the first user request falls within the management permission scope corresponding to the user level; wherein, the first user request includes items selected by the user to be used;

[0067] In this embodiment, the item corresponding to this method is a key in the rail transit system. The basis for classifying the items into different levels during hierarchical management is the various staff and passengers in the rail transit system. Passengers do not have management authority. Staff members have management authority based on their job functions. For example, the train conductor has the highest management authority for all functional keys on the train, the highest management personnel of the rail transit hub have the highest management authority for all functional keys equipped in the hub, other personnel in charge have partial management authority in turn, and basic functional personnel have the lowest management authority. Basic functional personnel can only request or reserve the use of the key corresponding to their smart device. Obtaining keys or querying tracks beyond their functional scope requires requesting approval from the next higher level of management authority, and can only use or view the key under approved conditions.

[0068] Step S106: When it is determined that the scope of the first user's request exceeds the management authority scope corresponding to the user level, a first message is sent to the user; when it is determined that the scope of the first user's request falls within the management authority scope corresponding to the user level, the item location information corresponding to the first user's request is determined; wherein, the first message is used to prompt the first user that the request is out of scope.

[0069] This step is mainly to ensure the proper use of keys and prevent others from accidentally taking and using them, which could cause security incidents. Therefore, users who do not have the right to use the keys are directly excluded, and only authorized users are informed of the location of the items they are requesting.

[0070] Step S108: Determine whether the item is stored in the item storage unit based on the item location information;

[0071] To facilitate key storage and retrieval, each hub in the rail transit system is equipped with a unified key storage unit. Therefore, the most convenient way to obtain items is to retrieve them directly from the storage unit. Alternatively, the initial user request can be initiated after the storage unit is accessed or by a smart device carried by staff members within the rail transit system. Determining whether an item is stored in the storage unit quickly identifies the user's request and whether the key has been retrieved. If the user has no specific need to retrieve the item, the request can be terminated directly.

[0072] Step S110: When at least one item corresponding to the first user's request is stored in the item storage unit, the item storage unit is opened so that the item can be retrieved; when all items corresponding to the first user's request are retrieved from the item storage unit, a second message is sent to the user; wherein, the second message contains multiple location information of the items corresponding to the first user's request.

[0073] Optionally, the location information of the items can be obtained by designing Bluetooth base stations and Bluetooth positioning tags on all items. It is known that to ensure the security of key use in the rail transit system, the number of keys corresponding to the same function is limited. When there are at least two keys and one key is in the item storage unit, the requesting user can directly retrieve the key from the storage unit. When there are at least two keys and both are retrieved, the second message contains the location information of all keys for that function, at which point the user can choose which key to retrieve.

[0074] Step S112: Receive a second user request, which includes the user-selected item location information, required time information, and usage location information;

[0075] Step S114: Based on the second user's request, generate multiple path strategies for obtaining items and send them back to the user.

[0076] Steps S112 and S114 of this method aim to solve the problem of a temporary need for a key when all keys have been used. That is, multiple paths are planned for the user to obtain the item for each key. When the user receives the path information, he / she can choose the most convenient path to get the key from the previous user based on the time and location information required by him / her.

[0077] The item classification management method disclosed in the above steps can fully ensure that the use of each key can be effectively recorded. Compared with the existing technology, it also proposes a solution to address temporary needs and timely allocation. It not only ensures the safety of key use and reduces safety hazards, but also fully fits the application scenarios of keys in the rail transit system and improves the efficiency of key operation.

[0078] In practice, users can choose any location information from the multiple location information of the requested items sent by the server to formulate their own plan for retrieving items from the previous user. For example, as an optional implementation, when all the items corresponding to the first user's request have been retrieved from the item storage unit, the second message sent back includes not only location information but also the usage end time. Users can wait for the user with the earliest usage end time to return the item before retrieving it, or users can directly retrieve the item from the location closest to the item storage unit based on the location information.

[0079] Combination Figure 4As shown, this embodiment proposes a specific solution for generating multiple path strategies for obtaining items based on the user's selected location information and feeding them back to the user. This solution includes the following steps:

[0080] Step S402: Based on the rail transit operation information, obtain the traffic trajectory corresponding to the location information of the item selected by the user;

[0081] Step S404: Based on the principles of shortest time and shortest path, calculate all paths to obtain the item by traversing all stops on the traffic trajectory using demand time information and location information.

[0082] Step S406: Generate a sixth message containing all path information for obtaining the item and send it back to the user.

[0083] The implementation process described in steps S402 to S406 above uses location information as the endpoint of the path search and the user's required time as the end time. It traverses all stops along the subsequent transportation trajectory of the retrieved item using path search principles, collecting all possible paths for the user to retrieve the item. As an optional implementation, all possible paths can be arranged sequentially according to either the shortest time to retrieve the item or the shortest distance to retrieve the item, assisting the user in making a selection. Inevitably, once the user selects a path, the server will simultaneously send that path to the current user of the item at the selected location information, so that the current user can meet the user on the path, transfer the item, and then send a message back to the server regarding the item transfer.

[0084] As an optional implementation, a display unit is provided on the item storage unit or smart device, and the sequentially arranged paths can be displayed on the display unit.

[0085] Combination Figure 2 As shown, the item tiered management method disclosed in the embodiment further provides users with a pre-booking function so that they can directly pick up the items at the pre-booked time. Specifically, the implementation of this function includes the following steps:

[0086] Step S202: Receive a third user request, which is a reservation application form, including the item to be used and the reserved usage time;

[0087] Step S204: Determine whether the item corresponding to the reservation application is available at the scheduled usage time;

[0088] Step S206: When at least one item corresponding to the reservation application is in an idle state, lock the right to use at least one idle item within the predetermined usage time range, and send a third message to the user, the third message indicating that the reservation was successful; when all items corresponding to the reservation application are in an active state, send a fourth message to the user, the third message indicating that the reservation failed.

[0089] Making reservations in advance via a reservation application form reduces congestion during peak hours and allows for early approval, avoiding delays caused by last-minute requests. Optionally, when multiple reservation applications are submitted simultaneously or at overlapping times, the application will be prioritized based on the stated purpose of the reservation or any additional user requests.

[0090] Considering certain special scenarios, such as emergencies requiring the use of items beyond authorized scope or urgent tasks that cannot wait for the previous item to be retrieved, expedited approval processes are needed to improve efficiency; for this scenario, Figure 3 The illustrated embodiment further proposes a solution to address the aforementioned problems in emergency situations, specifically including:

[0091] Step S302: Determine the priority of the first user request;

[0092] Step S304: When the priority of the first user's request is higher than the management authority and reaches the preset priority, determine the location information of the item corresponding to the first user's request and send a fifth message to the user; wherein, the fifth message contains multiple location information of the item corresponding to the first user's request.

[0093] Based on the various events handled by the rail transit system, the server is pre-configured with scenarios requiring emergency key allocation for multiple unforeseen events, and different priorities are assigned to each scenario. When a temporary event occurs and meets the preset conditions, the location information of the requested object is directly fed back so that the user can obtain the item promptly. Optionally, when a user issues their first request, they need to attach a reason for the request, or directly select the priority of the request using a preset priority button, so that the server can quickly determine the urgency of the event after receiving the request.

[0094] As an optional implementation, a spare key can be preset in the item storage unit. This spare key cannot be used in general emergencies, but can only be used when the priority of the emergency is too high and the preset high-level management authority is approved.

[0095] Combination Figure 4 As shown, in this embodiment, to prevent items such as keys from being lost or confused during use, the method further includes the following steps:

[0096] Step S502: Receive a fourth user request, which is used to query the trajectory of the item selected by the user;

[0097] Step S504: Determine the query area range and query time range corresponding to the fourth user's request based on the management permission range corresponding to the user level.

[0098] Step S506: A seventh message is sent to the user, which includes trajectory information of the user-selected item within the query area and query time range.

[0099] That is, the embodiment can locate the item by tracking its trajectory and finding the end point of the trajectory to prevent loss; at the same time, it can clearly understand the corresponding function of the item based on the usage status of the item taken by the user, and then distinguish items with similar appearances based on the corresponding function.

[0100] As an optional implementation, this method also includes: pre-setting an inspection cycle for item retrieval, and generating a retrieval report for each item corresponding to each function after the end of any inspection cycle, so that the rail transit system can immediately analyze whether there are any abnormalities in item retrieval and their causes, or adjust the quantity of items stored, thereby providing better prerequisite support for the operation of the rail transit system.

[0101] When the item classification management method based on rail transit disclosed in this invention is applied to a rail transit system, on the one hand, it promotes the standardized use of keys by setting permissions for keys, thus ensuring the security of key storage and use; on the other hand, it improves the efficiency of key use by prioritizing user requests and allocating keys in a timely manner to deal with emergency situations.

[0102] In an embodiment of the present invention, an electronic device is also provided, which includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor runs the computer program, it implements the rail transit-based item classification management method disclosed in the above embodiments.

[0103] The aforementioned computer programs may run in a processor or be stored in memory (or computer-readable storage media). Computer-readable media includes both permanent and non-permanent, removable and non-removable media, and information storage can be implemented by any method or technology. Information may be computer-readable instructions, data structures, program modules, or other data. Examples of computer storage media include, but are not limited to, phase-change memory (PRAM), static random access memory (SRAM), dynamic random access memory (DRAM), other types of random access memory (RAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), flash memory or other memory technologies, CD-ROM, digital versatile optical disc (DVD) or other optical storage, magnetic tape, magnetic magnetic disk storage or other magnetic storage devices, or any other non-transfer medium that can be used to store information accessible by a computing device. As defined herein, computer-readable media does not include temporary computer-readable media, such as modulated data signals and carrier waves.

[0104] These computer programs may also be loaded onto a computer or other programmable data processing equipment to cause a series of operational steps to be performed on the computer or other programmable equipment to produce a computer-implemented process, thereby providing instructions that execute on the computer or other programmable equipment for implementing the process. Figure 1 One or more processes and / or boxes Figure 1 The steps for the functions specified in one or more boxes can be implemented using different modules, and different steps can be implemented using different modules.

[0105] This embodiment provides such a system, which can be called a rail transit-based item classification management system, the system comprising:

[0106] The first determining module is used to determine the levels of item hierarchical management and the corresponding management permissions for each level; the first receiving module is used to receive a first user request, wherein the first user request includes an item selected by the user for use; the first judging module is used to judge whether the scope of the first user request falls within the management permission scope corresponding to the user level; when it is judged that the scope of the first user request exceeds the management permission scope corresponding to the user level, a first message is sent back to the user; when it is judged that the scope of the first user request falls within the management permission scope corresponding to the user level, the location information of the item corresponding to the first user request is determined; wherein, the first message is used to prompt the first user that the request is out of bounds; the second judging module is used to determine the item location information corresponding to the first user request. Based on the item location information, it is determined whether the item is stored in the item storage unit; when at least one item corresponding to the first user's request is stored in the item storage unit, the item storage unit is opened to allow the item to be retrieved; when all items corresponding to the first user's request have been retrieved from the item storage unit, a second message is sent back to the user; wherein, the second message contains multiple location information of the items corresponding to the first user's request; a second receiving module is used to receive the second user request, the second user request including the item location information selected by the user, the required time information, and the usage location information; a generating module is used to generate multiple path strategies for obtaining items based on the second user request and send them back to the user.

[0107] The system is used to implement the steps of the rail transit-based item classification management method disclosed in the above embodiments, and therefore, the steps already described will not be repeated here.

[0108] For example, the system also includes:

[0109] The third receiving module is used to receive a third user request, which is a reservation application form, including the item to be used and the scheduled usage time. The third judging module is used to judge whether the item corresponding to the reservation application form is available at the scheduled usage time. When at least one item corresponding to the reservation application form is available, the module locks the right to use at least one available item within the scheduled usage time range and sends a third message to the user, which indicates that the reservation was successful. When all items corresponding to the reservation application form are not available, the module sends a fourth message to the user, which indicates that the reservation failed.

[0110] For example, the system also includes:

[0111] The fourth judgment module is used to judge the priority of the first user's request; the second determination module is used to determine the location information of the item corresponding to the first user's request when the priority of the first user's request is higher than the management authority and reaches the preset priority, and to send a fifth message to the user; wherein, the fifth message contains multiple location information of the item corresponding to the first user's request.

[0112] For example, the generation module in this system generates multiple path strategies for obtaining items based on the second user's request and feeds them back to the user's execution unit, including:

[0113] The acquisition unit is used to acquire the traffic trajectory corresponding to the location information of the item selected by the user based on the rail transit operation information; the calculation unit is used to calculate all paths to acquire the item by traversing all stops of the traffic trajectory according to the shortest time and shortest path principles, using demand time information and location information; the feedback generation unit is used to generate a sixth message containing all path information of the acquired item and send it back to the user.

[0114] For example, the system also includes:

[0115] The fourth receiving module is used to receive a fourth user request, which is used to query the trajectory of an item selected by the user.

[0116] The third determination module is used to determine the query area range and query time range corresponding to the fourth user's request based on the management permission range corresponding to the user level.

[0117] The feedback module is used to send a seventh message to the user, which includes trajectory information of the user-selected item within the query area and time range. This is optional. The information provided by the feedback module can be displayed as images or text on the item storage unit or the display unit of the smart device.

[0118] This invention discloses a hierarchical management method and system for items based on rail transit. First, it checks the permissions of received user requests. If the request falls within the authorized scope, it determines whether the requested item is in storage, and then performs different operations accordingly. Specifically, if the item is in storage, it is directly opened and retrieved; if the item is in use, multiple paths are planned based on its location for retrieval. In other words, this invention, by setting hierarchical management permissions for items and prioritizing user requests, restricts users from accessing items while simultaneously tracking the real-time location of items by monitoring user movements. This not only ensures key security and improves key usage efficiency but also enables timely allocation of items and response to emergencies within the rail transit system.

[0119] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
