Detailed Description
To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined objects, the following detailed description is given to an embodiment of a geo-fence based location data processing system and its effects according to the present invention with reference to the accompanying drawings and preferred embodiments.
Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the steps as a sequential process, many of the steps can be performed in parallel, concurrently or simultaneously. In addition, the order of the steps may be rearranged. A process may be terminated when its operations are completed, but may have additional steps not included in the figure. A process may correspond to a method, a function, a procedure, a subroutine, a subprogram, etc.
An embodiment of the present invention provides a geo-fence based location data processing system, as shown in fig. 1, including M first mobile terminals corresponding to M first user ids, a second mobile terminal corresponding to N second user ids, a first database, a processor, and a memory storing a computer program, where the first database, the processor, and the memory storing the computer program may be disposed in one server, as shown in fig. 1 for example. Each second user id corresponds to one or more first user ids, M > > N, the first mobile terminal is installed with a preset first app, the second mobile terminal is installed with a preset second app, and it should be noted that the first app and the second app may be different apps or two different app user sides of the same app. The first database stores target information records, and the target information record field comprises a first user id, first user identification information, preset geo-fence information, a preset card punching time list and a second user id. The second app logged in by the second user has a right to acquire all target information records corresponding to the second user id, the preset card punching time list can be dynamically adjusted based on the card punching time setting information sent by the second app, the preset geo-fence information can be dynamically adjusted based on the geo-fence setting information sent by the second app, and it can be understood that different preset card punching times can be set for different first users, and preset card punching frequencies can also be different. The preset card punching time list comprises a first preset card punching time, a second preset card punching time, …, an ith preset card punching time, …, 1,2 and 3 …;
when the processor executes the computer program, the following steps are implemented:
step S1, acquiring first user detection information acquired by the first app in real time at a certain moment in a preset ith card punching time period, matching the first user detection information with first user identification information in the first database, executing step S2 if the matching is successful, and otherwise, sending first card punching failure information at the ith preset card punching time to the corresponding second app, wherein the ith card punching time period is [ ith preset card punching time-preset first time interval, ith preset card punching time + preset first time interval ];
as an embodiment, the first user detection information may be living human face detection information, and correspondingly, the first user identification information is human face identification information of the first user id. The first time interval is determined according to a specific application scenario, and as an embodiment, the first time interval is 15 minutes. Taking the ith time of checking the card as nine am of a certain day as an example, the ith time period of checking the card is 8:45-9:15 of the day.
Step S2, obtaining ith card punching position information collected by the first app in real time, judging whether the ith card punching position information is located in a preset geo-fence corresponding to the first user, if so, sending information for completing ith preset card punching operation to the second app, otherwise, sending second card punching failure information at the ith preset card punching moment to the second app, wherein the precision of the ith card punching position information is smaller than the boundary precision of the preset geo-fence.
It should be noted that the preset geo-fence accuracy may be directly a boundary area of a region, for example, a boundary area corresponding to a city, and the accuracy of the ith card punching position information is set to be smaller than the boundary accuracy of the preset geo-fence, so that when the first user is located in the geo-fence boundary area, it is possible to avoid erroneous judgment due to position jitter, and improve the accuracy of the system in judging that the first user is located in the geo-fence, and particularly, for an area adjacent to the geo-fence boundary is an area that the first person cannot reach or cannot reach in general, for example, the adjacent area is a sea area, a river area, a mountain peak, and the like. In this scenario, if the reported ith card punching position information is in an adjacent area, the ith card punching position information can be directly judged to be located in the geo-fence area, so that misjudgment can be reduced, and the system accuracy can be improved.
The system provided by the embodiment of the invention can improve the accuracy of the position data processing system, reduce the calculation amount of the position data processing system and improve the accuracy of identifying whether the target personnel are positioned in the preset area.
In order to further improve the accuracy of the system, as an embodiment, each first user id is bound with a corresponding first mobile terminal id, the target information record further includes the first mobile terminal id, the system further includes a second database, configured to store terminal position information reported by the first mobile terminal at every preset second time interval, where the second time interval is smaller than the first time interval, and the accuracy of the terminal position is greater than the accuracy of the card punching position, it can be understood that the card punching position is the card punching position acquired by the first app in real time, including the card punching position at the i-th preset time, and also includes the instant card punching position in an example where the accuracy of the card punching position at the i-th preset time is the same as the accuracy of the instant card punching position, for example, the accuracy of the card punching position may be set to 8-bit geohash, and the accuracy of the terminal position acquired by the first mobile terminal is 16-bit geohash accuracy, the boundary accuracy of the preset geofence is 12-bit geohash accuracy.
When it is determined in step S2 that whether the ith card punching location information is located in the preset geo-fence corresponding to the first user, before sending second card punching failure information at the ith preset card punching time to the second app, the method may further include the following steps:
step S10, obtaining, from the second database, terminal location information of a first mobile terminal id corresponding to the first user id that is closest to the current time, and determining whether the terminal location information is located in a preset electronic fence corresponding to the first user, if the terminal location information is located in the preset electronic fence corresponding to the first user, sending information of completing an ith preset card punch operation to the second app, and if not, sending second card punch failure information at the ith preset card punch time to the second app. Therefore, when the jitter, the flying and other wrong judgments occur due to the fact that the first app collects the card punching position in real time, calibration is performed through the terminal position information of the first terminal corresponding to the first user, and the accuracy of system judgment is improved.
In order to detect whether the first user leaves the geo-fenced area within two preset time-punching intervals when the two preset time-punching intervals of the first user are large, as an embodiment, when the processor executes the computer program, the following steps are further implemented:
step S11, obtaining, from the second database, terminal location information reported by the first user id in a preset ix-th time period, and determining whether a ratio of all terminal location information reported by location information outside the geo-fence in the terminal location information reported in the ix-th time period is greater than a preset ratio threshold, if so, sending first warning information to the corresponding second app, where the ix-th time period belongs to [ ith preset time of getting a card, ith +1 st preset time of getting a card ].
It can be understood that, by determining whether the ratio of all terminal location information reported in the ix time period and located outside the geo-fence in the terminal location information reported in the ix time period is greater than a preset ratio threshold, it can be preliminarily determined that the first user may leave the geo-fence area with the corresponding first terminal, and further determination may be made by letting the first user make a further determination by instant card punching, as an embodiment, the step S11 further includes:
step S12, a first card punching instruction sent by the second app based on the first early warning information is obtained and sent to the corresponding first app;
step S13, determining whether first user detection information sent by the first app is received within a preset third time interval from issuing of a first instant card punching instruction, if so, executing step S14, and if not, or if not, sending second warning information to the second app;
step S14, first instant card punching position information acquired by the first app in real time is acquired, whether the first instant card punching position information is located in a preset geo-fence corresponding to the first user or not is judged, if yes, first instant card punching operation information is sent to the second app, the first early warning information is eliminated, and if not, third early warning information is sent to the second app.
It can be understood that the early warning levels of the second early warning information and the third early warning information are higher than the early warning level of the first early warning information, and through further verification, when step S14 further determines that the instant card punching is successful, the first early warning information is eliminated, so that the accuracy of the system for determining whether the first user is in the corresponding geo-fence is improved based on the card punching position of the first app and the terminal position of the first mobile terminal, which are verified and supported by each other.
In addition to the above embodiments, there may also be a scenario in which the user leaves the corresponding geo-fence without carrying the corresponding first mobile terminal, as an embodiment, when the processor executes the computer program, the following steps may be implemented:
step S100, obtaining all terminal location information reported by the first user id in a preset iy time period from the second database, and if the terminal location information is located at the same location and the location is located in a geo-fence corresponding to the first user id, sending fourth warning information to the corresponding second app, where the iy time period belongs to [ an ith preset time of punching a card, an (i + 1) th preset time of punching a card ].
It is understood that, through step S100, it may be preliminarily determined that the first user may leave the corresponding geo-fence without carrying the corresponding first mobile terminal, and in order to improve the accuracy of the determination, as an embodiment, the step S100 may further include:
step S200, a second card punching instruction sent by the second app based on the fourth early warning information is obtained and sent to the corresponding first app;
step S30, determining whether first user detection information sent by the first app is received within a preset fourth time interval from issuing the card punch instruction, if the first user detection information is received and matched with the first user identification information in the first database, sending second instant card punch operation information to the second app, and eliminating the fourth warning information, and if the fourth warning information is not received or the received first user detection information is not matched with the first user identification information in the first database, sending fifth warning information to the second app.
It should be noted that the warning priority of the fifth warning information is higher than the warning priority of the fourth warning information. Each priority information may include a corresponding early warning reason, and may also be distinguished in different forms on the display interface, for example, by adopting different colors.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
