Description

Technical Field

[0001] This invention belongs to the field of elderly care service scheduling technology, specifically a county-level integrated scheduling platform for elderly care service resources. Background Technology

[0002] In elderly care services, the dispatch platform is the core of achieving efficient allocation of elderly care resources. The core logic of existing mainstream elderly care resource dispatch platforms is that resource carriers such as caregivers' mobile phones and meal delivery vehicles are online in real time throughout the process. By obtaining their real-time latitude and longitude coordinates, they complete intelligent dispatching and scheduling based on the needs of the elderly.

[0003] The above-mentioned model is well-suited for urban elderly care scenarios. Due to the comprehensive mobile network coverage in cities, resource carrier terminals can remain continuously online, enabling efficient scheduling and making it a mature solution in the industry. However, due to the unique geographical environment of county-level elderly care scenarios, the above-mentioned model reveals obvious adaptability defects.

[0004] The core difference between county-level elderly care and urban elderly care lies in the complexity of the geographical environment. The service area covers remote mountainous areas, the border areas between villages and towns, and other regions. These areas are affected by terrain, lagging communication infrastructure, etc., resulting in insufficient mobile network signal coverage. There are generally communication blind spots with weak, intermittent, or even interrupted signals. This is an objective reality that county-level elderly care cannot change in the short term.

[0005] The existing dispatch platform does not take into account the unique environment of counties and lacks a communication blind spot adaptation mechanism, still using the dispatch logic of urban scenarios. When resource carriers enter communication blind spots, terminals cannot upload real-time signals and coordinates, and the platform will mistakenly judge them as offline and unavailable. When dispatching orders, it will skip nearby resources and assign remote resources, which not only wastes elderly care resources, but also increases service costs and reduces dispatch efficiency, failing to meet the actual needs of elderly care in counties.

[0006] Therefore, the present invention provides an integrated scheduling platform for elderly care service resources based on county-level coordination. Summary of the Invention

[0007] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0008] The technical solution adopted by this invention to solve its technical problem is:

[0009] One of the objectives of this invention is to provide a county-level integrated scheduling platform for elderly care service resources, comprising:

[0010] The communication blind spot geofencing construction module constructs a geofence for the communication blind spot coverage area within a county;

[0011] Entry parameter recording module: Real-time monitoring of the communication status of elderly care service terminals. When an elderly care service terminal enters a communication blind zone geofence, it records the entry time and entry vector parameters of the elderly care service terminal.

[0012] The time-space positioning module calculates the expected duration of the elderly care service terminal within the communication blind zone geofence based on the entry time, entry vector parameters, and the preset service task information corresponding to the elderly care service terminal, and marks the status of the elderly care terminal as time-space locked.

[0013] Instruction processing module: During the expected duration, the module maintains the elderly care service terminal in the active candidate state in the scheduling engine and stores new scheduling instructions for the elderly care service terminal in a silent buffer. When the elderly care service terminal re-establishes a communication connection, the module extracts the actual exit time and releases the instructions in the silent buffer or re-triggers resource reallocation based on the deviation between the actual exit time and the expected duration.

[0014] As a further improvement of the present invention, the specific process of constructing a geofence for communication blind spots in the county-level elderly care service coverage area is as follows:

[0015] Within the county-level elderly care service coverage area, collect and record the latitude and longitude coordinates of areas where mobile network signals of elderly care service terminals are interrupted and areas where signal strength is lower than the communication threshold of elderly care service terminals;

[0016] Based on the GIS geographic information system, the latitude and longitude coordinates are calibrated, and all the calibrated latitude and longitude coordinates are integrated to form a geofence for communication blind spots in the county's elderly care service coverage area.

[0017] As a further improvement of the present invention, the communication state specifically includes:

[0018] The communication status specifically includes: whether the mobile network signal of the elderly care service terminal is interrupted, and whether the signal strength is lower than the communication threshold of the elderly care service terminal.

[0019] As a further improvement of the present invention, the specific determination process when the elderly care service terminal enters the communication blind zone geofence is as follows:

[0020] Based on the communication status of each elderly care service terminal, it is determined whether the elderly care service terminal has entered the communication blind zone geofence. If the mobile network signal of the elderly care service terminal is interrupted, or the signal strength of the elderly care service terminal is lower than the elderly care service terminal communication threshold, it is determined that the elderly care service terminal has entered the communication blind zone geofence.

[0021] As a further improvement of the present invention, the specific determination process when the elderly care service terminal enters the communication blind zone geofence also includes:

[0022] The real-time location coordinates of each elderly care service terminal are collected and compared with the latitude and longitude coordinates of the communication blind zone geofence in real time. The location coordinates are used to determine whether the elderly care service terminal has entered the communication blind zone geofence. The real-time location coordinates are latitude and longitude coordinates.

[0023] As a further improvement of the present invention, the specific process of recording the entry time and entry vector parameters of the elderly care service terminal is as follows:

[0024] When it is determined that the elderly care service terminal has entered the geographical fence of the communication blind zone, the entry time of the elderly care service terminal is recorded. The entry time is specifically the system standard time when the real-time positioning coordinates of the elderly care service terminal first match and fall into the geographical fence of the communication blind zone.

[0025] The entry vector parameters of the elderly care service terminal are collected and recorded. The entry vector parameters specifically include the moving direction and moving speed of the elderly care service terminal when entering the communication blind zone geofence, as well as the latitude and longitude coordinates corresponding to the entry point.

[0026] As a further improvement of the present invention, the specific calculation process for the expected duration is as follows:

[0027] The system obtains the entry time and entry vector parameters of the elderly care service terminal, and obtains preset service task information, including preset service location and preset service duration.

[0028] Based on the movement direction, movement speed, and latitude and longitude coordinates in the entry vector parameters, and combined with the boundary range of the communication blind zone geofence, the movement trajectory of the elderly care service terminal within the communication blind zone geofence and the estimated travel time to reach each preset service location are calculated.

[0029] By combining the preset service durations and overlaying the estimated travel time of the elderly care service terminal between various service locations within the communication blind zone geofence, and taking the entry time as the starting point, the estimated duration of the elderly care service terminal within the communication blind zone geofence is calculated.

[0030] As a further improvement of the present invention, the specific process of marking the spacetime locking is as follows:

[0031] After calculating the expected duration of operation, the status of the elderly care service terminal is marked as a spatiotemporal locked state. The spatiotemporal locked state is used to indicate that the elderly care service terminal is within the communication blind zone geofence, unable to upload latitude and longitude coordinates in real time, but is in normal service status. At the same time, the expected duration of operation and preset service task information of the elderly care service terminal are locked.

[0032] As a further improvement of the present invention, the specific process of storing the newly added scheduling instructions for the elderly care service terminal into the silent buffer is as follows:

[0033] Using the expected duration as the time range, the elderly care service terminals in the time-space locked state are maintained as alternative active states in the scheduling engine. The alternative active state indicates that the elderly care service terminal is not offline and has service capabilities. The scheduling engine does not judge the elderly care service terminal as an unavailable resource, but only restricts the real-time scheduling instruction push to the elderly care service terminal.

[0034] All new scheduling instructions for elderly care service terminals that are in a time-space locked state are stored in a dedicated silent buffer in real time. The silent buffer temporarily stores the instructions and does not push them to elderly care service terminals within the communication blind zone geofence.

[0035] As a further improvement of the present invention, the specific process of releasing the instructions in the silent buffer or re-triggering resource reallocation is as follows:

[0036] When the elderly care service terminal is detected to have re-established a valid mobile network communication connection or LoRa local area network communication connection for the first time, the actual time of the elderly care service terminal's exit is extracted.

[0037] Based on the entry time, calculate the actual duration of the actual exit time and the entry time, and then calculate the time deviation between the actual duration and the expected duration.

[0038] The time deviation value is compared with the preset reasonable deviation threshold. If the time deviation value does not exceed the preset reasonable deviation threshold, all new scheduling instructions in the silent buffer are immediately pushed to the elderly care service terminal and released, and the status of the elderly care service terminal is updated from time and space lock to normal online status.

[0039] If the time deviation exceeds the preset reasonable deviation threshold, the newly added scheduling instructions in the silent buffer will be removed from the elderly care service terminal and redistributed to the elderly care service terminal that is in a normal online state.

[0040] The second objective of this invention is to provide a method for integrated scheduling of elderly care service resources based on county-level coordination, comprising:

[0041] Step S10: Construct geofencing for communication blind spots in the elderly care service coverage area within the county;

[0042] Step S20: Monitor the communication status of the elderly care service terminal in real time. When the elderly care service terminal enters the communication blind zone geofence, record the entry time and entry vector parameters of the elderly care service terminal.

[0043] Step S30: Based on the entry time, entry vector parameters, and the preset service task information corresponding to the elderly care service terminal, calculate the expected duration of the elderly care service terminal within the communication blind zone geofence, and mark the status of the elderly care service terminal as spatiotemporally locked.

[0044] Step S40: During the expected duration, maintain the elderly care service terminal in the alternative active state in the scheduling engine, and store the new scheduling instructions for the elderly care service terminal in the silent buffer. When the elderly care service terminal re-establishes the communication connection, extract the actual exit time, and release the instructions in the silent buffer or re-trigger resource reallocation based on the deviation between the actual exit time and the expected duration.

[0045] The beneficial effects of this invention are as follows:

[0046] The core benefit of this invention lies in breaking the conventional wisdom that signal interruption equates to an inability to schedule services. It innovatively demonstrates that even in highly planned scenarios like elderly care services (where work orders are readily available), precise logical scheduling can still be achieved despite signal interruption. Its key advantage lies in employing a core logic that compensates for real-time signal loss using prior task information. It eliminates the need for real-time signal transmission; by relying solely on key information such as the start point, end point, and service duration associated with the work order, it enables the scheduling and management of elderly care service terminals within blind spots. This invention precisely addresses this technological gap.

[0047] Meanwhile, this solution avoids complex big data processing steps, does not require analysis of real-time traffic flow across the county, and only calculates a few key parameters of the current work order. The amount of computation is minimal, which fully meets the practical application requirements of fast processing speed and can run stably without the need for additional investment of a large amount of computing resources.

[0048] This invention completely solves the problems of terminal offline misjudgment and resource waste caused by communication blind spots in county-level elderly care. It avoids the unreasonable scheduling of platforms skipping terminals in nearby blind spots and assigning remote resources, significantly improving the utilization rate of county-level elderly care resources, reducing service costs, and ensuring the continuous and efficient development of elderly care services in special areas such as remote mountainous areas and village-town border areas. It perfectly adapts to the objective reality of complex geographical environment and lagging communication infrastructure in county-level elderly care, and truly meets the actual service needs of county-level elderly care. Attached Figure Description

[0049] The invention will now be further described with reference to the accompanying drawings.

[0050] Figure 1 This is a platform module diagram of an integrated scheduling platform for elderly care service resources based on county-level coordination, as proposed in this invention.

[0051] Figure 2 This is a flowchart illustrating the steps of an integrated scheduling method for elderly care service resources based on county-level coordination, as described in this invention. Detailed Implementation

[0052] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0053] Example 1

[0054] like Figure 1 As shown in the embodiment of the present invention, an integrated scheduling platform for elderly care service resources based on county-level coordination includes:

[0055] The communication blind spot geofencing construction module constructs a geofence for the communication blind spot coverage area within a county;

[0056] In the communication blind spot geofencing construction module, the specific process of constructing a communication blind spot geofencing for the elderly care service coverage area within a county is as follows:

[0057] Within the county-level elderly care service coverage area, for remote mountainous areas and areas with weak mobile network signals at the border of villages and towns, the latitude and longitude coordinates of areas where mobile network signals of elderly care service terminals are interrupted and areas where signal strength is lower than the communication threshold of elderly care service terminals are collected and recorded in real time.

[0058] Based on the GIS geographic information system, the latitude and longitude coordinates of each of the aforementioned areas with weak mobile network signals were calibrated one by one. All the calibrated latitude and longitude coordinates were integrated to form a geographic fence for communication blind spots in the county's elderly care service coverage area.

[0059] It should be noted that the communication threshold of the elderly care service terminal is specifically the minimum mobile network signal strength threshold required for the elderly care service terminal to stably transmit information related to elderly care service scheduling, and the minimum mobile network signal strength threshold is preset according to the communication module type of the elderly care service terminal and the minimum bandwidth requirement for scheduling information transmission.

[0060] Entry parameter recording module: Real-time monitoring of the communication status of elderly care service terminals. When an elderly care service terminal enters a communication blind zone geofence, it records the entry time and entry vector parameters of the elderly care service terminal.

[0061] The specific process for real-time monitoring of the communication status of the elderly care service terminal in the entry parameter recording module is as follows:

[0062] The dispatch platform continuously collects and monitors the communication status and real-time location coordinates of all elderly care service terminals within the county. The real-time location coordinates are uploaded by the elderly care service terminals through integrated communication modules, which include mobile network communication modules, LoRa local area network communication modules, and Beidou short message communication modules. The communication status specifically includes whether the mobile network signal of the elderly care service terminal is interrupted and whether the signal strength is lower than the elderly care service terminal's communication threshold. The real-time location coordinates are latitude and longitude coordinates.

[0063] In the entry parameter recording module, when the elderly care service terminal enters the communication blind zone geofence, the specific process of recording the entry time and entry vector parameters of the elderly care service terminal is as follows:

[0064] The dispatch platform directly determines whether an elderly care service terminal has entered the communication blind zone geofence based on the communication status of each terminal. If the mobile network signal of the terminal is interrupted, it is directly determined that the terminal has entered the communication blind zone geofence. If the signal strength of the terminal is lower than the communication threshold, it is also directly determined that the terminal has entered the communication blind zone geofence. Otherwise, it determines whether the terminal has entered the communication blind zone geofence through the real-time positioning coordinates. The specific process is as follows:

[0065] The scheduling platform will collect the real-time location coordinates of each elderly care service terminal and compare them with the latitude and longitude coordinates of the communication blind zone geofence constructed by the communication blind zone geofence construction module in real time. The platform will determine whether the elderly care service terminal has entered the communication blind zone geofence range by the real-time location coordinate landing point.

[0066] When the comparison result determines that the real-time positioning coordinates of the elderly care service terminal fall within the geographical fence of the communication blind zone for the first time, the scheduling platform immediately records the entry time of the elderly care service terminal. The entry time is specifically the system standard time when the real-time positioning coordinates of the elderly care service terminal first match and fall within the geographical fence of the communication blind zone.

[0067] Meanwhile, the scheduling platform synchronously collects and records the entry vector parameters of the elderly care service terminal. The entry vector parameters specifically include the moving direction and moving speed of the elderly care service terminal when entering the communication blind zone geofence, as well as the specific latitude and longitude coordinates corresponding to the entry point, providing basic data support for subsequent calculation of the expected duration of the elderly care service terminal within the communication blind zone geofence.

[0068] The time-space positioning module calculates the expected duration of the elderly care service terminal within the communication blind zone geofence based on the entry time, entry vector parameters, and the preset service task information corresponding to the elderly care service terminal, and marks the status of the elderly care terminal as time-space locked.

[0069] In the time-based positioning module, the specific process of calculating the expected duration of the elderly care service terminal within the communication blind zone geofence, based on the entry time, entry vector parameters, and the preset service task corresponding to the elderly care service terminal, is as follows:

[0070] The scheduling platform obtains the entry time and entry vector parameters of the elderly care service terminal recorded by the entry parameter recording module, and simultaneously obtains the preset service task information corresponding to the elderly care service terminal. The preset service task information includes the preset service location and preset service duration.

[0071] Based on the movement direction, movement speed, and latitude and longitude coordinates of the entry point in the entry vector parameters, and combined with the boundary range of the communication blind zone geofence, the movement trajectory of the elderly care service terminal within the communication blind zone geofence and the estimated travel time to reach each preset service location are calculated.

[0072] Combining the preset service durations in the preset service tasks with the estimated travel time of the elderly care service terminal between service locations within the communication blind zone geofence, and taking the entry time as the starting point, the estimated duration of the elderly care service terminal within the communication blind zone geofence is calculated. The estimated duration is the total estimated duration from the entry time of the elderly care service terminal until the completion of the preset service tasks and exit of the communication blind zone geofence.

[0073] For example, the entry time of the elderly care service terminal is... The entry vector parameter is the moving speed. The direction of movement is from the preset service point A within the geofence of the communication blind zone, and the latitude and longitude coordinates of the entry point are the eastern boundary point of the geofence of the blind zone. Geofencing boundary for communication blind spots: The fence is an irregular polygon with an entry point. Straight-line distance to preset service point A Service point A to the exit point on the west side of the fence straight-line distance Preset service task parameters: Preset service duration for service point A The roads within the blind spot are simple rural roads, and the speed of passage is calculated as 80% of the speed of entry and movement. There are no additional detours.

[0074] Entry point calculated based on segmented duration Estimated travel time to service point A: Service point A to departure point Estimated travel time: Preset service duration: Service (no additional service points, single-point service only);

[0075] Expected duration The estimated duration is calculated as the sum of the passage time for each segment and the preset service time, i.e.: Combined with the entry time It can be simultaneously predicted that the time when the elderly care service terminal is expected to leave the communication blind spot is 9:00 + 38.75 min = 9:38:45;

[0076] In summary, the estimated duration of the elderly care service terminal in the communication blind zone is 38.75 minutes. The county-level dispatch center uses this as a benchmark to lock the terminal's spatiotemporal status until it actually leaves the blind zone or completes the preset service task.

[0077] In the spatiotemporal locking module, the specific process of marking the state of the elderly care service terminal as spatiotemporally locked is as follows:

[0078] After calculating the expected duration of the elderly care service terminal within the communication blind zone geofence, the scheduling platform marks the status of the elderly care service terminal as a spatiotemporal locked state. The spatiotemporal locked state is used to indicate that the elderly care service terminal is within the communication blind zone geofence, cannot upload latitude and longitude coordinates in real time, but is in a normal service state. At the same time, the expected duration of the elderly care service terminal and the preset service task information are locked to avoid the platform misjudging that it is offline and unavailable and making invalid order dispatch.

[0079] Instruction processing module: During the expected duration, the module maintains the elderly care service terminal in the active candidate state in the scheduling engine and stores new scheduling instructions for the elderly care service terminal in a silent buffer. When the elderly care service terminal re-establishes a communication connection, the module extracts the actual exit time and releases the instructions in the silent buffer or re-triggers resource reallocation based on the deviation between the actual exit time and the expected duration.

[0080] In the instruction processing module, the specific process of maintaining the elderly care service terminal in the active candidate state in the scheduling engine and storing new scheduling instructions for the elderly care service terminal in the silent buffer during the expected duration is as follows:

[0081] The scheduling platform uses the estimated duration calculated by the time-space locking module as the time range to maintain the elderly care service terminal in the time-space locking state as the alternative active state in the scheduling engine. The alternative active state indicates that the elderly care service terminal is not offline and has service capabilities. The scheduling engine does not judge it as an unavailable resource, but only restricts the real-time scheduling command push to it.

[0082] Meanwhile, the scheduling engine will store all new scheduling instructions received for the elderly care service terminal in a dedicated silent buffer in real time. The silent buffer temporarily stores the instructions and does not push them to elderly care service terminals within the communication blind zone geofence, ensuring that the instructions are not lost.

[0083] In the instruction processing module, when the elderly care service terminal re-establishes a communication connection, the actual exit time is extracted, and based on the deviation between the actual exit time and the expected duration, the specific process of releasing the instructions in the silent buffer or re-triggering resource reallocation is as follows:

[0084] The scheduling platform continuously monitors the communication status of the elderly care service terminal. When it detects that the elderly care service terminal has re-established a valid mobile network communication connection or LoRa local area network communication connection for the first time, it immediately extracts the actual exit time of the elderly care service terminal. The actual exit time is the system standard time when the elderly care service terminal leaves the communication blind zone geofence, restores communication for the first time, and uploads real-time positioning coordinates.

[0085] Simultaneously, the actual service execution feedback data of the elderly care service terminal within the communication blind zone geofence is obtained. Based on the entry time recorded by the entry parameter recording module, the actual duration of the actual exit time and entry time is calculated. Then, the time deviation between the actual duration and the expected duration calculated by the time-conditioning module is obtained.

[0086] The time deviation value is compared with a preset reasonable deviation threshold. If the time deviation value does not exceed the preset reasonable deviation threshold, the scheduling platform immediately pushes and releases all new scheduling instructions in the silent buffer to the elderly care service terminal. At the same time, the status of the elderly care service terminal is updated from time and space lock to normal online status, the alternative active status restriction in the scheduling engine is removed, and normal scheduling is restored.

[0087] If the time deviation value exceeds the preset reasonable deviation threshold, the scheduling platform triggers a resource reallocation mechanism, stripping the newly added scheduling instructions in the silent buffer from the elderly care service terminal and reallocating them to other elderly care service terminals in normal online status within the county. At the same time, based on the actual exit time and actual service execution feedback data, the status information of the terminal is updated and the spatiotemporal lock is released. Simultaneously, the time deviation data is entered into the county's communication blind spot database to provide data support for subsequent optimization of the expected duration calculation model.

[0088] It should be noted that the preset reasonable deviation threshold is specifically 5-10 minutes. Its setting is determined based on the characteristics of the county-level elderly care service scenario, including but not limited to fluctuations in the speed of rural roads in communication blind spots, reasonable errors in the preset service duration, deviations in the positioning accuracy of elderly care service terminals, and the impact of terrain in the blind spot on the movement trajectory. It can be flexibly adjusted according to the actual geographical environment and service mode of different counties, and is used to define the reasonable fluctuation range between the actual duration and the expected duration of elderly care service terminals in communication blind spots.

[0089] Example 2

[0090] like Figure 2 As shown, based on the specific implementation process of Embodiment 1, the present invention provides a method for integrated scheduling of elderly care service resources based on county-level coordination, including:

[0091] Step S10: Construct geofencing for communication blind spots in the elderly care service coverage area within the county;

[0092] Step S20: Monitor the communication status of the elderly care service terminal in real time. When the elderly care service terminal enters the communication blind zone geofence, record the entry time and entry vector parameters of the elderly care service terminal.

[0093] Step S30: Based on the entry time, entry vector parameters, and the preset service task corresponding to the elderly care service terminal, calculate the expected duration of the elderly care service terminal within the communication blind zone geofence, and mark the status of the elderly care service terminal as spatiotemporally locked.

[0094] Step S40: During the expected duration, maintain the elderly care service terminal in the alternative active state in the scheduling engine, and store the new scheduling instructions for the elderly care service terminal in the silent buffer. When the elderly care service terminal re-establishes the communication connection, extract the actual exit time, and release the instructions in the silent buffer or re-trigger resource reallocation based on the deviation between the actual exit time and the expected duration.

[0095] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.

By combining the preset service durations and overlaying the estimated travel time of the elderly care service terminal between various service locations within the communication blind zone geofence, and taking the entry time as the starting point, the estimated duration of the elderly care service terminal within the communication blind zone geofence is calculated.

8. The integrated scheduling platform for elderly care service resources based on county-level coordination as described in claim 1, characterized in that: The specific process of marking the spacetime locking is as follows: After calculating the expected duration of operation, the status of the elderly care service terminal is marked as a spatiotemporal locked state. The spatiotemporal locked state is used to indicate that the elderly care service terminal is within the communication blind zone geofence, unable to upload latitude and longitude coordinates in real time, but is in normal service status. At the same time, the expected duration of operation and preset service task information of the elderly care service terminal are locked.

9. The integrated scheduling platform for elderly care service resources based on county-level coordination as described in claim 1, characterized in that: The specific process of storing new scheduling instructions for elderly care service terminals into the silent buffer is as follows: Using the expected duration as the time range, the elderly care service terminals in the time-space locked state are maintained as alternative active states in the scheduling engine. The alternative active state indicates that the elderly care service terminal is not offline and has service capabilities. The scheduling engine does not judge the elderly care service terminal as an unavailable resource, but only restricts the real-time scheduling instruction push to the elderly care service terminal. All new scheduling instructions for elderly care service terminals that are in a time-space locked state are stored in a dedicated silent buffer in real time. The silent buffer temporarily stores the instructions and does not push them to elderly care service terminals within the communication blind zone geofence.
