Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such techniques, methods, and apparatus should be considered part of the specification.

In all examples shown and discussed herein, any specific values should be construed as illustrative only and not limiting. Accordingly, other instances of the exemplary embodiment may have different values.

It should be noted that like numerals and letters refer to like items in the following figures, so once an item is defined in one figure, it does not require further discussion in subsequent figures.

At present, for field personnel who need to go out to work, such as salesmen and urban management team members, because their working locations are not fixed, they need to report their location in time through comprehensive positioning devices such as GPS and network on the handheld mobile terminal during working hours. to facilitate the supervision of managers. However, in the related art, after obtaining the position information of the person to be monitored, the manager can only analyze the movement trajectory of the person to be monitored one by one from the massive position data, and judge whether there is any abnormality during the working hours, and the workload is extremely high. It will not only consume a lot of manpower and material resources, but also prone to inaccurate analysis.

In view of this, the present application provides a method and device for monitoring an abnormality of a person's position.

FIG. 1 is a schematic flowchart of a method for monitoring an abnormality of a person's position according to an embodiment of the present application. As shown in FIG. 1 , a method for monitoring abnormality of personnel position provided in this embodiment includes:

Step 101: Obtain the current position information of the person to be monitored, where the current position information includes the current position coordinates of the person to be monitored and the first time corresponding to the current position coordinates;

Step 102: When the first time corresponding to the current position coordinates is within the preset working time range, determine the target working time period in which the first time is located according to at least one pre-divided working time period;

Step 103, according to the target working time period and the current position information of the person to be monitored, determine whether the current position information is abnormal; wherein, the abnormality includes a stay behavior and no reporting behavior;

Step 104: When the current location information of the person to be monitored is abnormal, report the abnormal current location information.

Specifically, in the above step 101, the current position information of the person to be monitored can be collected in real time by using the GPS module in the preset application program App, wherein the current position information includes the current position coordinates and the first time corresponding to the current position coordinates. Exemplarily, if the current position information is P1 (116.350629, 37.432777), 10:30, it means that the person to be monitored is at the position whose coordinates are P1 (116.350629, 37.432777) at 10:30. It should be noted that the GPS module in the preset App can acquire and upload the current location information of the person to be monitored according to a certain collection frequency, for example, the collection frequency is 10 to 20 times per minute. It should be understood that if the collection frequency is set too small, a large amount of current position information of the person to be monitored will be obtained, resulting in data redundancy, which is not conducive to improving the real-time performance of the algorithm; on the contrary, if the collection frequency is set too large, it will not be possible. The real-time movement trajectory of the person to be monitored is obtained, and the abnormal current position information cannot be found in time; therefore, the collection frequency is set to 10 to 20 times/min, which effectively balances the real-time and accuracy of the above-mentioned abnormal personnel position monitoring method . In addition, the mobile app analyzes and judges the respective logged-in users (persons to be monitored), does not occupy service resources, and calculates quickly and further, which further ensures real-time performance.

Optionally, before performing step 102, it can be judged whether the first time corresponding to the current position coordinates is within the preset working time range, if the first time is not within the preset working time range, it means that it is not working time at this time, Therefore, there is no need to process the current position information, and this design method is more conducive to improving the real-time performance of the above method. Further, the preset working time is divided into multiple working time periods. For example, the preset working time is 8:30-18:00, and the preset working time range includes the first working time period 8:30-12:00. 00 and the second working time period 14:00～18:00, then still take the first time as 10:30 as an example, obviously, it is in the first working time period, that is, the first working time period 8:30 ~12:00 is the target working time period.

It can be understood that a stay in one place refers to the behavior of the person to be monitored in a certain area for more than a certain period of time, and no reporting refers to the behavior of the person to be monitored that continues to fail to report their own location information within a preset period of time. In the above step 103, after determining the target working time period, according to the target working time period and the current position information of the person to be monitored, it can be judged whether there is a stop behavior and no reporting behavior in the current position information, so as to analyze the behavior of the person to be monitored in real time. It can not only improve the supervision efficiency of managers, but also provide a basis for the work assessment of the personnel to be monitored.

FIG. 2 is a schematic flowchart of another method for monitoring an abnormality of a person's position provided by the embodiment of FIG. 1 . Please refer to FIG. 2. In the above step 103, according to the target working time period and the current position information of the person to be monitored, the steps of judging whether the current position information is abnormal include:

Step 1031: Determine whether the current location information is the location information obtained for the first time within the preset working time range;

Step 1032: If yes, determine the start time of the preset working time range, and determine whether the location information of the person to be monitored is abnormal according to the start time and the first time corresponding to the current position coordinates;

Step 1033: If no, obtain the historical location information of the person to be monitored, and determine whether the location information of the person to be monitored is abnormal according to the historical location information and the first time corresponding to the current location coordinates.

Specifically, after obtaining the current position information of the person to be monitored, according to the first time included in the current position information, it is determined whether the current position information obtained this time is the first current position information obtained within the preset working time range; If not, it is necessary to obtain the collected historical location information of the person to be monitored, and further determine whether the location information of the person to be monitored is abnormal in combination with the historical location information and the first time corresponding to the current location coordinates; The current location information of the person to be monitored can be determined according to the first time and the start time of the preset working time range whether the person to be monitored has no reporting behavior. Obviously, this design method is conducive to quickly finding anomalies in a large amount of current position information, and ensures the real-time and accuracy of the method for monitoring personnel position anomalies.

Optionally, in the above step 1032, according to the start time and the first time corresponding to the current position coordinates, the step of determining whether the position information of the person to be monitored is abnormal includes:

comparing the first time difference with the first preset duration;

If the first time difference is greater than the first preset time length, the person to be monitored has no reporting behavior;

Specifically, when the current location information acquired this time is the first current location information acquired within the preset working time range, the difference between the first time and the starting time of the preset working time range is calculated; If the difference is greater than the first preset time period, it means that the person to be monitored has no-report behavior; on the contrary, if the difference between the two is less than or equal to the first preset period of time, it means that the person to be monitored has no unreported behavior. Optionally, the first preset duration is 20-30 minutes. If the current location information is P1 (116.350629, 37.432777), 10:30, the preset working time is 8:30～18:00, and the first preset time is 20 minutes, then the first time is 10:30, and the working time range The starting time is 8:30, and the difference between the two is 2 hours. Since 2 hours exceeds the first preset time period, it is necessary to report the unreported behavior of the personnel to be monitored.

It can be seen that this design method has low computational complexity, which is conducive to quickly finding anomalies in a large amount of current location information, ensuring the real-time performance of the personnel location anomaly monitoring method, and further improving the management efficiency of managers.

Optionally, please continue to refer to FIG. 2, the historical location information includes the historical location coordinates of the person to be monitored and the second time corresponding to the historical location coordinates;

In the above step 1033, the steps of determining whether the location information of the person to be monitored is abnormal according to the historical location information and the first time corresponding to the current location coordinates include:

determining the third time in the historical location information when the location information was obtained for the last time;

In this embodiment, when the current location information acquired this time is not the first current location information acquired within the preset working time range, the acquired historical location information of the person to be monitored needs to be further acquired. Wherein, the historical location information includes all the historical location coordinates of the person to be monitored within the second preset time period before the first time and the second time respectively corresponding to the historical location coordinates, from which the last time in the historical location information is determined. After the third time when the location information is obtained, it is determined whether the person to be monitored has no-report behavior according to the first time and the third time, which ensures the accuracy of analyzing the abnormal location information of the person to be monitored.

FIG. 3 is another schematic flowchart of the method for monitoring an abnormality of a person's position provided by the embodiment of FIG. 1 . Please refer to FIG. 3 , according to the first time and the third time, the steps of judging whether the current location information is abnormal include:

Step S1, judging whether the third time is within the target working time period;

Step S2, if no, the person to be monitored has no reporting behavior within the target working time period;

Step S3: If yes, determine the activity range of the person to be monitored according to the current location information and the historical location information.

Specifically, when the third time is not within the above target working time, that is, when the first time and the third time are in different working time periods, it can be directly determined that the person to be monitored has no reporting behavior during the target working time period. Exemplarily, if the preset working time is 8:30-18:00, the first working time period is 8:30-12:00, the second working time period is 14:00-18:00, and the current location The information is P1 (116.350629, 37.432777), 10:30, and the last acquired location information in the historical location information is P2 (116.350693, 37.432733), 15:30, because 10:30 and 15:30 are located in different working time periods respectively , so the personnel to be monitored have no reporting behavior during the target working time period from 14:00 to 18:00.

Optionally, when the third time is not within the target working time period, the above-mentioned method for monitoring abnormality of personnel position further includes:

If it exists, the person to be monitored has no reporting behavior in other working time periods.

It can be understood that there are various ways of dividing the preset working time, which can be divided into multiple working time periods. For example, the preset working time is 8:30-18:00, and the preset working time includes One working time period 8:30～11:30, the second working time period 12:00～14:00 and the third working time period 15:00～18:00, if the first time is 17:30, When the third time is 9:00, it can be judged that the personnel to be monitored also have no reporting behavior during the second working time period, thereby further improving the real-time performance of the method for monitoring abnormal personnel positions.

FIG. 4 is another schematic flowchart of the method for monitoring an abnormality of a person's position provided by the embodiment of FIG. 1 . Please refer to FIG. 4, in the above step S3, when the third time is within the target working time period, according to the current position information and the historical position information, the steps of determining the activity range of the person to be monitored include:

S31, calculate the minimum circumcircle of the historical position coordinates and the current position coordinates;

S32, compare the first preset radius and the radius of the minimum circumscribed circle;

S33. If the radius of the minimum circumscribed circle is smaller than the first preset radius, the person to be monitored has a staying behavior in the target working time period;

S34. If the radius of the minimum circumscribed circle is greater than or equal to the first preset radius, the person to be monitored does not have a stop behavior within the target working time period.

Specifically, if the third time is within the target working time period of the first time, the minimum circumscribed circle of each historical position coordinate and the current position coordinate is calculated. It should be understood that the minimum circumscribed circle indicates that the person to be monitored is in the second The activity range within the preset time period can therefore be determined by comparing the radius of the minimum circumscribed circle with the first preset radius to determine whether the person to be monitored has a stop behavior during the target working time period. Exemplarily, in this embodiment, the incremental method can be used to calculate the circumscribed circle of each coordinate. The calculation method is simple, and it is convenient to accurately and quickly determine the activity range of the person to be monitored, thereby providing a basis for subsequent analysis of the movement trajectory of the person to be monitored. in accordance with.

In this embodiment, the first preset radius is 300-500 meters. For example, the first preset radius is 400 meters and the second preset duration is 30 minutes, that is to say, when the activity radius of the person to be monitored does not exceed 400 meters within 30 minutes, it will be determined as a stay behavior .

It should be noted that, in this embodiment, the inspection range specified by the personnel to be monitored is set as a circle with a radius between 300 and 500 meters. However, in some other embodiments of the present application, the inspection scope of the personnel to be monitored can be determined according to The actual management requirement is set, which is not limited in this embodiment.
