FIG. 1 is a flow chart of a position information displaying method according to an embodiment of the present invention. As shown in FIG. 1, the position information displaying method according to the present embodiment may comprise:

101: A server receives and records position point information transmitted regularly by the portable locator, wherein the position point information comprises information for positioning a position point of the portable locator;

In an optional embodiment of the present invention, prior to step 101, the method comprises:

The monitoring terminal sends an activation request to the server, wherein the activation request comprises an identifier of the portable locator; wherein the identifier of the portable locator for example comprises a QR code of the portable locator or a card number of a Subscriber Identity Module (SIM) set in the portable locator;

The server performs authorization and verification for the monitoring terminal according to the identifier of the portable locator, makes the monitoring terminal can focus on the portable locator, and activates the portable locator corresponding to the identifier, makes the activated portable locator can transmit position point information of the portable locator to the server.

Furthermore, the monitoring terminal can transmit to the activated portable locator via the server a time interval or a reporting time of reporting the position point information, make the portable locator regularly transmits the position point information of the portable locator to the server according to the time interval or reporting time; or

The server transmits to the portable locator a time interval or a reporting time of reporting the position point information, makes the portable locator regularly transmits the position point information of the portable locator to the server according to the time interval or reporting time; or

The portable locator presets a time interval or a reporting time of reporting the position point information, and regularly transmits the position point information of the portable locator to the server according to the above time interval or reporting time.

102: determining a location area corresponding to the position point information according to the position point information;

In an optional embodiment of the present invention, step 102, upon specific implementation, comprises:

according to the position point information, considering a natural geographical area where a position point corresponding to the position point information locates as the location area corresponding to the position point information; for example, assume when the natural geographical area is a school, a boundary of the school is a boundary of the natural geographical area, all the position points occur in the school belong to the natural geographical area of the school; or

taking the position point corresponding to the position point information as a center, considering a surrounding area of a preset radius as the location area corresponding to the position point information; for example, taking the position point reported by the locator as a center, considering an area within a surrounding scope of a preset radius (e.g., a radius of 20 meters) as the location area corresponding to the position point; or

judging there are multiple neighbor position points around the position point corresponding to the position point information, and determining the location area corresponding to the position point information according to a distance between the position point and the multiple neighbor position points; for example, if there are multiple neighbor position points around the position point as reported by the locator, assume the preset distance of neighborhood is 10 meters, an area formed by the neighbor position points within 10 meters (inclusive) around the position point can be considered as the location area corresponding to the position point.

103: making statistics of the number of position points corresponding to the position point information in the location area among recorded position point information, and judging whether the number of position points exceeds a threshold; executing step 104 if yes, and executing step 108 if no;

Upon specific implementation, statistics is performed for the number of position points corresponding to the position point information in the location area among recorded position point information in a time period as same as a preset time period where a positioning time of the position point information lies; for example, making statistics of multiple position point information recorded by the server and reported by the locator within a preset time period (one day or several hours), respectively determining position points corresponding to the multiple position point information, according to each position point, determining which position points fall within the location area determined in step 102, and making statistics of the number of position points falling within the location area determined in step 102; for example, in a certain location area, presetting two hours to make statistics of the number of position points once, specifically, from the positioning time of the first position point information, a statistic is performed as to whether the number of position points appearing in the location area within two hours exceeds a threshold, and the position points appearing in the location area after two hours can only participate in the next statistic of the number of position points in the location area.

In the present embodiment, the preset threshold can be specifically set according to different location areas. For example, when the monitored person is a child, school and home, these two location areas, are safe location areas, stay in the two location areas is relatively longer, there are relatively more position point information recorded in the two location areas, so the threshold for the number of position points in the two location areas is relatively larger.

104: marking the location area or position points in the location area;

Corresponding to step 103, the marking in step 104 corresponds to the preset time period.

If the number of position points does not exceed the threshold, step 108 will be executed, namely, not marking the location area or position points in the location area.

105: displaying the marked location area or position points in the location area in an electronic map.

Upon specific implementation, step 105 comprises:

displaying the marked location area or position points in the location area differently according to the number of position points corresponding to the recorded position point information contained in the location area; and/or

displaying the marked location area or position points in the location area differently according to a time difference between a positioning time of a first recorded position point in the location area and a positioning time of a last recorded position point.

For example, displaying differently as stated above specifically comprises:

displaying in the electronic map the marked location area or position points in the location area with different sizes, colors, brightness and transparency according to the number of the position points and/or a length of the time difference.

FIG. 2 is a flow chart of a position information displaying method according to another embodiment of the present invention. As shown in FIG. 2, in an optional embodiment of the present invention, the method further comprises after step 102:

Step 106: obtaining a positioning time corresponding to a first appearing position point in the location area and a positioning time corresponding to a last appearing position point in the location area, and calculating a time length between the two positioning times.

Step 107: judging whether the time length reaches a time threshold;

In the present embodiment, the preset time threshold can be specifically set according to different location areas. For example, when the monitored person is a child, school and home, these two location areas, are safe location areas, stay in the two location areas is relatively longer, so the time threshold for the stay in the two location areas is relatively larger.

If the time length reaches the time threshold, step 104 and step 105 will be performed, namely, marking the location area or position points in the location area, and displaying the marked location area or position points in the location area in an electronic map.

If the time length does not reach the time threshold, step 108 will be performed, namely, not marking the location area or position points in the location area.

FIG. 3 is a flow chart of a position information displaying method according to another embodiment of the present invention. As shown in FIG. 3, in an optional embodiment of the present invention, the method further comprises after step 106:

Step 109: in the time length, calculating a proportion of the number of position points appearing in the location area to the number of position points corresponding to all position point information recorded in the time length, and judging whether the proportion is higher than a proportion threshold;

In the present embodiment, the preset proportion threshold can be specifically set according to different location areas. For example, when the monitored person is a child, school and home, these two location areas, are safe location areas, stay in the two location areas is relatively longer, so the proportion of the number of position points appearing in the two location areas to the number of position points corresponding to all recorded position point information is relatively higher. For example, the home is taken as an example. A time period from 10:00 pm to 10:00 am is a preset statistic time period. Among all position point information recorded in the 12 hours, most position points appear at home due to sleep time at night. After getting up in the morning, the monitored person will leave the location of home for many reasons such as going to school or going shopping. Hence, the proportion of position points occurring in the location area of home is very high, that is to say, the time length of stay in the location area can be determined and thereby whether the location area is a familiar or safe location area be determined according to the number of all position points obtained from statistics in the preset time period, and according to a proportion of the number of position points appearing in a certain location area to the number of all position points.

If the proportion determined in step 109 is higher than the proportion threshold, step 104 and step 105 will be performed, namely, marking the location area or position points in the location area, and displaying the marked location area or position points in the location area in an electronic map.

If the proportion determined in step 109 is lower than the proportion threshold, step 108 will be performed, namely, not marking the location area or position points in the location area.

Noticeably, in the present embodiment, the server can further receive multiple position point information transmitted by the portable locator in a continuous time period; and mark the position point corresponding to each position point information in a temporal order according to the positioning time corresponding to each position point information, and generate a movement track of the portable locator.

Noticeably, it the present embodiment, to simplify the number of displayed identifiers and improve user distinguishing efficiency, when there are multiple position point information in the same geographical location area, only one display identifier can be marked.

In the embodiment of the present invention, the server can receive and record position point information regularly transmitted by the portable locator in a preset time period, the position point information comprising information for positioning the position point where the portable locator lies; determine the location area corresponding to the position point information according to the position point information; make statistics of the number of position points corresponding to the position point information in the location area among recorded position point information; mark the location area or position points in the location area if the number of position points exceeds the threshold; or obtain a positioning time corresponding to a first appearing position point in the location area and a positioning time corresponding to a last appearing position point in the location area, and calculate a time length between the two positioning times; judge whether the time length reaches a time threshold, and mark the location area or position points in the location area if the time length reaches the time threshold; or in the time length, calculate a proportion of the number of position points appearing in the location area to the number of position points corresponding to all position point information recorded in the time length, and mark the location area or position points in the location area if the proportion is higher than a preset value.

Then, the marked location area or position points in the location area are displayed in an electronic map. Specifically, the marked location area or position points in the location area are displayed in the electronic map with different sizes, colors, brightness and transparency according to the number of the position points and/or a length of the time difference. For example, home and school, as two geographic location areas, are location areas with the longest stay time as well as the safest location areas, and can be displayed with a blue mark which can be larger; again for example, grandparents' home is a location area with longer stay as well as a relatively safe area and can be displayed with a yellow mark which can be slightly smaller.

Then, the guardian holding the monitoring terminal determines the position information of the person under guardianship and carrying the portable locator through the mark displayed on the electronic map, and can obtain security information through the position information; the guardian can further determine the track of the person under guardianship and carrying the portable locator according to a movement track of the portable locator.

Hence, the technical solutions of embodiments of the present invention can improve the user experience as well as the subsequent missing person-seeking effectiveness.

606: The designated server transmits the reminder message to the monitoring terminal bound to the portable locator.

In practical application, when the monitored person is monitored by two or more guardians, the monitoring terminal held by each guardian can perform verification and authorization via the sever so that each guardian can learn about the position security information of the monitored person at any time;

Correspondingly, the designated server queries the communication whitelist of the portable locator and obtains the communication address of the monitoring terminal comprised in the communication whitelist of the portable locator;

Send the reminder message to the monitoring terminal corresponding to the obtained communication address of the monitoring terminal, make the monitoring terminal, according to the reminder message, sends an operation instruction to the portable locator via the designated server.
