A point of interest is a term in a geographic information system that broadly refers to a geographic object that can be abstracted as a point, e.g., a point of interest can be a house or a mailbox, etc.

Currently, a method for point of interest tagging is proposed based on a map application that provides a physical structural representation of a venue (e.g., a shopping mall), and in addition, the map application can provide a unique venue directory to facilitate searching for various categories of points of interest (e.g., gourmet or clothing, etc.), and the search results can be presented on a floor map within the venue as well as on a list that provides all the search results located within the venue.

In the interest point labeling method based on the map application, the interest point can be described as a label type such as a mall, a school, a hospital, or a platform.

With reference to the above description, the electronic map updating method of the present application will be described below from the perspective of a server, and referring to fig. 3, an embodiment of the electronic map updating method in the embodiment of the present application includes:

101. in a first period, a server receives first device association information sent by a first Bluetooth gateway, wherein the first device association information comprises an identifier of an Internet of things device, identifiers of M Bluetooth beacons and M pieces of signal strength information, the signal strength information in the M pieces of signal strength information is used for indicating that the Internet of things device receives the signal strength of the Bluetooth beacons, and M is an integer greater than or equal to 1;

in this embodiment, in the first period, the first bluetooth gateway may actively report the first device association information to the server, or the server actively sends a request to the first bluetooth gateway, and the first bluetooth gateway responds to the request and then reports the first device association information to the server. The first period refers to a period, for example, the first period is 1 second, 10 seconds, or 1 minute, and the like, which is not limited herein.

The first device association information comprises two parts of information, one part of information is beacon information, the beacon information comprises identifications of M Bluetooth beacons and M signal strength information, the other part of information is IoT (Internet of things) device information, and the IoT device information comprises the identifications of the IoT devices. Specifically, the identifier of the bluetooth beacon may be a MAC address of the bluetooth beacon, a UUID of the bluetooth beacon, an equipment serial number of the bluetooth beacon, or other identifiers that can uniquely indicate the bluetooth beacon. The identity of the IoT device may be a MAC address of the IoT device, a UUID of the IoT device, a device serial number of the IoT device, or other identity that can uniquely indicate the IoT device. The Signal Strength information may be Received Signal Strength Indication (RSSI), and each piece of Signal Strength information respectively represents the Signal Strength of the IoT device receiving one bluetooth beacon.

It should be noted that the IoT device communicates with the bluetooth gateway by using an IoT communication Protocol, where the IoT communication Protocol includes an access Protocol and a communication Protocol, the access Protocol is generally responsible for networking and communication among devices in the subnet, and the communication Protocol is a device communication Protocol operating on an Internet Transmission Control Protocol/Internet Protocol (TCP/IP), and performs data exchange and communication through the Internet. Currently, the protocols used by most IoT devices are typically WIFI or bluetooth based connectivity.

102. The server generates a first device mapping relation corresponding to the first period according to the first device association information, wherein the first device mapping relation comprises association relations among Bluetooth beacons derived from the M Bluetooth beacons, the Internet of things device and the first Bluetooth gateway;

in this embodiment, the server may generate a first device mapping relationship corresponding to the first period according to the first device association information, where the first device mapping relationship includes an association relationship among the bluetooth beacon, the IoT device, and the first bluetooth gateway.

In an implementation manner, for convenience of understanding, please refer to fig. 4, where fig. 4 is a schematic diagram of a first device mapping relationship in this embodiment, as shown in the figure, a server generates a network topology structure diagram based on first device association information, where the network topology structure diagram may be a Directed Acyclic Graph (DAG), where the first device mapping relationship may be represented as the DAG shown in fig. 4, a bluetooth beacon is a node with an incoming degree of 0, a topology structure diagram is constructed for bluetooth gateways, each bluetooth gateway and a beacon group managed by the bluetooth gateway form a DAG, and finally, the device nodes are added to the whole DAG, so as to construct the topology structure diagram of the whole electronic map. Based on this, the information of the IoT device can be acquired from any node access.

It should be noted that, in graph theory, if a directed graph cannot go through several edges from any vertex back to the point, the graph is a DAG. A directed graph does not necessarily form a ring from one point to another point through two routes, and therefore a directed acyclic graph does not necessarily translate into a tree, but any directed tree is a directed acyclic graph.

In another implementation, the first device mapping relationship may be represented as a generated device mapping table, as shown in table 1, where table 1 is an illustration of the first device mapping relationship.

TABLE 1

As can be seen from table 1, each IoT device may connect three bluetooth beacons, and each IoT device communicates with one bluetooth gateway. The server can find a downstream node through the Bluetooth gateway C, namely, the Bluetooth gateway A is obtained, then the downstream node IoT equipment A is found based on the Bluetooth gateway A, finally, the Bluetooth beacon connected with the IoT equipment A in the current period is determined, and if the Bluetooth beacon connected with the IoT equipment A is changed, the mapping relation of the first equipment can be updated.

103. The server determines a first interest point position of the Internet of things equipment in the electronic map according to a first equipment mapping relation corresponding to the first period;

in this embodiment, the server determines the coordinate position of the IoT device by using a bluetooth indoor positioning technology according to the first device mapping relationship obtained in the first period, and then may determine the coordinate position as the first point of interest of the IoT device in the electronic map.

Specifically, the bluetooth indoor positioning technology means through laying the bluetooth gateway in the environment, snatch the beacon information that bluetooth beacon on the article transmitted through the bluetooth gateway, and the bluetooth gateway passes back the beacon information of collecting to the server through wired network, thereby the server obtains the real-time coordinate of bluetooth beacon on the article of being positioned through the location settlement based on the known coordinate of bluetooth gateway. The indoor position resolving is divided into a terminal side resolving mode and a network side resolving mode, the terminal side resolving means that the terminal can directly resolve the position of the terminal without network transmission. Outdoor is represented by a Global Positioning System (GPS), and indoor is required to locate coordinate position information transmitted by bluetooth beacon. At present, the indoor positioning technology is mainly solved by a network side.

104. And the server updates the map data of the electronic map according to the first interest point position.

In this embodiment, the server updates the map data of the electronic map according to the acquired first point of interest position, where the first point of interest position represents a point of interest position on the IoT device. The updating manner may be to add the location of the point of interest of the IoT device or to move the native location of the IoT device.

In the embodiment of the application, a method for updating an electronic map is provided, and through the method, the position of an interest point of an internet of things device can be marked in the electronic map, and map data is updated according to the position of the interest point, so that the position of the interest point is described as the internet of things device which can be accessed to a Bluetooth gateway, and compared with places and fixed objects, the internet of things device has smaller granularity, and therefore the method is beneficial to improving the description capacity and the query capacity of the positions of objects.

If the IoT device has a communication connection relationship with more than three bluetooth beacons at the same time, more than three pieces of signal strength information can be obtained, taking the signal strength information as RSSI as an example, and assuming that M is 5, for easy understanding, please refer to table 2, where table 2 is one illustration of M pieces of signal strength information.

TABLE 2

Based on the RSSI of each bluetooth beacon in table 2, the 5 RSSI can be ranked in descending order, thereby obtaining the target information sequence as shown in fig. 3.

TABLE 3

Bluetooth beacon's sign	RSSI
		Bluetooth beacon A	70
Bluetooth beacon D	55
		Bluetooth beacon C	50
Bluetooth beacon E	35
		Bluetooth beacon B	30

As can be seen from table 3, the target information sequence is 70,55,50,35, and 30, based on which the first three pieces of signal strength information (i.e., RSSI) are determined from the target information sequence, and taking table 3 as an example, 70,55, and 50 are selected, so as to obtain the bluetooth beacon corresponding to each piece of signal strength information (i.e., RSSI), that is, the bluetooth beacon a, the bluetooth beacon D, and the bluetooth beacon C are obtained, where the three bluetooth beacons are the bluetooth beacons derived from M bluetooth beacons. Since the IoT device will also communicate with the first bluetooth gateway, the constructed first device map includes bluetooth beacons originating from the M bluetooth beacons, the internet of things device, and the first bluetooth gateway.

It should be noted that, the M signal strength information may also be arranged in an ascending order, and then the three pieces of signal strength information in the opposite direction are taken out, so as to obtain the bluetooth beacons from the M bluetooth beacons.

Secondly, in the embodiment of the present application, a manner of generating a first device mapping relationship is provided, through the manner, three pieces of larger signal strength information can be preferentially selected from the M pieces of signal strength information, and since positioning can be achieved by three points, bluetooth beacons corresponding to the three pieces of signal strength information are used as the bluetooth beacon having the largest association degree with the IoT device, and a device mapping relationship is established by using the bluetooth beacon, so that accuracy of device positioning is improved.

Optionally, on the basis of the embodiment corresponding to fig. 3, in another optional embodiment provided in the embodiment of the present application, the determining, by the server, a first point of interest position of the internet of things device in the electronic map according to the first device mapping relationship corresponding to the first period may specifically include:

the server acquires Bluetooth beacons from the M Bluetooth beacons according to a first device mapping relation corresponding to a first period, wherein the Bluetooth beacons from the M Bluetooth beacons comprise a first Bluetooth beacon, a second Bluetooth beacon and a third Bluetooth beacon;

the server acquires first signal intensity information corresponding to the first Bluetooth beacon, second signal intensity information corresponding to the second Bluetooth beacon and third signal intensity information corresponding to the third Bluetooth beacon according to the first equipment association information;

the server acquires first position information corresponding to the first Bluetooth beacon, second position information corresponding to the second Bluetooth beacon and third position information corresponding to the third Bluetooth beacon;

the server determines a first distance according to first signal strength information corresponding to the first Bluetooth beacon;

the server determines a second distance according to second signal strength information corresponding to the second Bluetooth beacon;

the server determines a third distance according to third signal strength information corresponding to the third Bluetooth beacon;

the server determines a first interest point position of the Internet of things equipment in the electronic map according to the first distance, the second distance, the third distance, the first position information, the second position information and the third position information.

In this embodiment, a method for determining a location of a first point of interest based on a triangulation method is described. First, the server may obtain a first bluetooth beacon, a second bluetooth beacon, and a third bluetooth beacon that communicate with the IoT device based on the first device mapping relationship corresponding to the first period. Then, according to beacon information in the first device association information, signal strength information corresponding to each bluetooth beacon is obtained, and therefore first signal strength information, second signal strength information and third signal strength information are obtained. In general, the position of the bluetooth beacon is fixed, and therefore, the server can acquire position information of each bluetooth beacon, wherein the position information can be expressed as two-dimensional coordinates. And finally, the server generates a corresponding distance by combining the signal strength information corresponding to each Bluetooth beacon, and solves the first interest point position of the IoT equipment in the electronic map based on the distance and the position information.

Specifically, taking the signal strength information as RSSI as an example, the RSSI can be converted into distance in the following manner:

d＝10^((ABS(RSSI)-A)/(10*n))；

where d represents the distance, RSSI represents the signal strength information, a represents the absolute value of the RSSI value at 1 meter from the IoT device, the range is typically set between 45 and 49, n represents the environmental attenuation factor, the test remediation is required, and the range is typically set between 3.25 and 4.5.

Based on this, the server determines a first distance (i.e., d1) from the first signal strength information (i.e., RSSI of the first bluetooth beacon to the IoT device), determines a second distance (i.e., d2) from the second signal strength information (i.e., RSSI of the second bluetooth beacon to the IoT device), determines a third distance (i.e., d2) from the third signal strength information (i.e., RSSI of the third bluetooth beacon to the IoT device),

in addition, the server may further acquire first location information (x1, y1) of the first bluetooth beacon, second location information (x2, y2) of the second bluetooth beacon, and third location information (x3, y3) of the third bluetooth beacon, respectively. After obtaining the distances from the unknown point to the three points, the coordinates of the unknown point may be solved, i.e., the first point of interest location of the IoT device in the electronic map is calculated. Since two circles intersect at one or two points (if intersecting), and three circles intersect at one point if intersecting, the unknown point to be solved is the intersection of three circles drawn with the three known points as the centers and the distances between the known points and the unknown points as the radii. Thus, the intersection of three known circles can be calculated using the following formula:

(x1–x)^2+(y1-y)^2＝r1^2；

(x2–x)^2+(y2-y)^2＝r2^2；

(x3–x)^2+(y3-y)^2＝r3^2；

where x and y are the coordinates representing the location of the first point of interest. It is understood that there are various ways to solve for the location of the first point of interest, which are not listed here.

In practical applications, there are three cases of locating the first point of interest, which will be described separately below.

Case one, three circles intersect at a point;

referring to fig. 5, fig. 5 is a schematic diagram illustrating the determination of the location of interest based on triangulation in the embodiment of the present application, as shown in the figure, each bluetooth beacon has a radiation range, and assuming that each radiation range is a circle, when three circles intersect at a point, the point is the first location of interest corresponding to the IoT device.

Case two, three circles intersect in a region;

referring to fig. 6, fig. 6 is another schematic diagram illustrating the determination of the location of an interest point based on triangulation in the embodiment of the present application, as shown in the figure, each bluetooth beacon has a radiation range, and assuming that each radiation range is a circle, when three circles intersect in an area, one point in the area is a first location of an interest point corresponding to an IoT device.

Case three, the three circles have a phase separation;

referring to fig. 7, fig. 7 is another schematic diagram illustrating the position of the point of interest determined based on triangulation in the embodiment of the present application, where each bluetooth beacon has a radiation range, and assuming that each radiation range is a circle, when there is a separation among the three circles, a point with the shortest distance from the first bluetooth beacon, the second bluetooth beacon, and the third bluetooth beacon may be selected as the first point of interest corresponding to the IoT device.

Secondly, in this application embodiment, provide a mode based on the first point of interest position is confirmed to the triangulation location method, through above-mentioned mode, utilize three bluetooth beacon's beacon information can realize the location of IoT equipment, on the one hand, three-point location's mode complexity is lower, is favorable to promoting the real-time of location, and on the other hand, three-point location can obtain comparatively accurate positioning result to promote the precision of location.

Optionally, on the basis of the embodiment corresponding to fig. 3, in another optional embodiment provided in the embodiment of the present application, the updating, by the server, the map data of the electronic map according to the first point of interest position may specifically include:

if the first interest point position meets the interest point rule avoiding condition, the server adjusts the first interest point position to obtain a first optimized interest point position;

if the first interest point position meets the position optimization condition, the server adjusts the first interest point position to obtain a second optimization interest point position;

if the first interest point position meets the interest point avoiding condition and the position optimizing condition, the server adjusts the first interest point position to obtain a third optimized interest point position;

and the server updates the map data of the electronic map according to the position from the first optimized interest point to the second optimized interest point or the third optimized interest point.

In this embodiment, a way of optimizing the location of the first point of interest is introduced. After obtaining the first point of interest location, the server may further determine whether the first point of interest location meets an interest avoiding condition, and if so, adjust the first point of interest location to obtain a first optimized point of interest location. If not, the position of the first interest point does not need to be adjusted. Exemplarily, it may further be determined whether the first interest point location satisfies a location optimization condition, and if so, the first interest point location is adjusted to obtain a second optimized interest point location. If not, the position of the first interest point does not need to be adjusted. Exemplarily, it may further be determined whether the first interest point location satisfies an interest point rule and condition, and determine whether the first interest point location satisfies a location optimization condition, and if both are satisfied, adjust the first interest point location to obtain a third optimized interest point location. If the first point of interest is not satisfied, the first point of interest position is not required to be adjusted.

Secondly, in the embodiment of the application, a mode for optimizing the position of the first interest point is provided, and through the mode, the position of the first interest point can be optimized based on the interest point avoiding condition and the position optimizing condition, so that the positioning accuracy and the positioning rationality are further improved.

Optionally, on the basis of the embodiment corresponding to fig. 3, in another optional embodiment provided in the embodiment of the present application, if the first point of interest location satisfies the point of interest avoiding condition, the server adjusts the first point of interest location to obtain a first optimized point of interest location, which may specifically include:

the server acquires an original interest point position in the electronic map;

if the distance between the original interest point position and the first interest point position is smaller than or equal to the distance threshold, the server determines that the first interest point position meets an interest point rule condition;

the server constructs a target area according to the position of the original interest point;

the server determines a first optimization interest point position from the target area;

the server replaces the first point of interest location with the first optimized point of interest location.

In this embodiment, a method for determining a location of an interest point based on a pair of interest point avoidance strategies is introduced. Because the interest points of the indoor map data or the outdoor map data are based on the information of the indoor static scene, and the position of the IoT device in the indoor map calculated based on the bluetooth positioning technology is superposed on the original static data of the indoor map, a situation that the position of a newly added interest point is superposed with the position of the original interest point may occur, and a corresponding interest point avoidance strategy needs to be adopted.

Specifically, the server may first determine, from map data existing in the electronic map, original location of interest points that may indicate other IoT devices, fixed areas, or the like, at which point the server determines that the first location of interest point satisfies the point of interest avoidance condition if a distance between the first location of interest point and one or more of the original location of interest points is less than or equal to a distance threshold. For ease of understanding, the method of optimizing the location of the first point of interest will be described below in connection with two cases.

In case one, there is an original interest point location whose distance from the first interest point location is less than or equal to a distance threshold;

for ease of understanding, please refer to fig. 8, fig. 8 is a schematic diagram illustrating an optimization process performed on a point of interest in the embodiment of the present application, where, as shown in the figure, if a distance between an original point of interest (a black dot in the figure) and a first point of interest (a white dot in the figure) is smaller than or equal to a distance threshold, it means that a probability that the original point of interest and the first point of interest coincide is high. Therefore, a circle with the original interest point as the center and the error range as the radius needs to be constructed, and the circle is the target area. A first optimized point of interest location is then selected from the target area and replaced with the first point of interest location.

Note that the error range may be a range in a room. According to the information of the indoor map provided by the map engine, the rooms of the indoor map are separated by spaces, and the error range is the radius of an inscribed circle of the spaces. Alternatively, the error range may also be a preset value, for example, 3 meters or 2 meters.

In case two, the distance between the original interest point positions and the first interest point position is smaller than or equal to the distance threshold;

for convenience of understanding, taking an example that the distances between the two original interest point locations and the first interest point location are both less than or equal to the distance threshold, please refer to fig. 9, where fig. 9 is another schematic diagram of performing optimization processing on the interest point locations in the embodiment of the present application, as shown in the figure, if the distances between the two original interest point locations (black dots in the figure) and the first interest point location (white dots in the figure) are both less than or equal to the distance threshold, that is, it indicates that the probability that the original interest point locations and the first interest point location coincide with each other is high. Therefore, two circles which respectively use the original interest point as the center of a circle and use the error range as the radius need to be constructed, and the position of the intersection point of the two circles is the target area. A first optimized point of interest location is then selected from the target area and replaced with the first point of interest location.

It should be noted that, if three or more original interest points exist and need to be avoided, the intersection positions of the circles corresponding to the original interest points are sequentially taken as optimized interest points.

In the embodiment of the application, a method for determining the position of the point of interest based on the point of interest avoidance strategy is provided, and by the method, the situation that the position of the point of interest of the IoT equipment is overlapped with the positions of other equipment or objects can be avoided, so that the position of the point of interest of the IoT equipment cannot be identified, therefore, the position of the point of interest with higher overlap ratio can be distinguished by using the point of interest avoidance strategy, and the definition and the distinguishing degree of the position of the point of interest are improved.

Optionally, on the basis of the embodiment corresponding to fig. 3, in another optional embodiment provided in the embodiment of the present application, if the first point of interest location satisfies the location optimization condition, the server adjusts the first point of interest location to obtain a second optimized point of interest location, which may specifically include:

the server acquires a type label of the Internet of things equipment;

if the type label of the Internet of things equipment is a preset type label, the server determines that the position of the first interest point meets the position optimization condition;

the server determines the placeable range of the Internet of things equipment according to the type label of the Internet of things equipment;

the server determines a second optimization interest point position from the placeable range;

the server replaces the first point of interest location with a second optimized point of interest location.

In this embodiment, a method for determining a location of a point of interest based on a device type tag is introduced. First, the server may determine a type tag of the IoT device through information of the IoT device included in the first device association information, and if the type tag is consistent with a preset type tag, it indicates that the first point of interest location satisfies a location optimization condition, that is, the point of interest location of the IoT device may be adjusted according to a placement policy. Different types of tags of the IoT devices generally correspond to different distribution areas in an indoor map application scenario, and therefore, a diversified placement strategy based on rules can be adopted, that is, a placeable range under the type of tags is determined, so that one location is selected from the placeable range as a second optimized interest point location, and the first interest point location is replaced by the second optimized interest point location, thereby realizing optimization of the interest point location.

In particular, for ease of understanding, the method of optimizing the location of the first point of interest will be described below in connection with three scenarios.

Scenario one, taking an IoT device as an intelligent trash can as an example, please refer to fig. 10, and fig. 10 is a schematic view of a scenario for optimizing a location of interest in an embodiment of the present application, as shown in the figure, a type label of the IoT device is "intelligent trash can", and the intelligent trash can is usually located in a rectangular border area range of an indoor space, so that the intelligent trash can is moved from a position (i.e., a first location of interest) shown in fig. 10 (a) to a position (i.e., a second optimized location of interest) shown in fig. 10 (B).

Scenario two, taking an IoT device as an example of a shared power bank, please refer to fig. 11, and fig. 11 is another schematic view of an optimized location of interest in the embodiment of the present application, as shown in the figure, a type label of the IoT device is "shared power bank", and the shared power bank is usually placed together with other internet of things devices, so that the shared power bank is moved from the position shown in fig. 11 (a) (i.e., the first location of interest) to the position shown in fig. 11 (B) (i.e., the second optimized location of interest).

Third, referring to fig. 12, fig. 12 is another schematic view of an exemplary embodiment of the present disclosure, in which an IoT device is a smart lamp, and the type label of the IoT device is "smart lamp", and the smart lamp is usually placed in a central location of a room, so that the shared power bank is moved from the location shown in fig. 12 (a) (i.e., the first location of interest) to the location shown in fig. 12 (B) (i.e., the second location of interest).

It can be understood that the following three examples are merely illustrative, and in practical applications, the placement strategy corresponding to the preset type tag may be set according to requirements. For example, devices such as smart printers, which are used less frequently, are often placed in corner areas of a space or the like.

In the embodiment of the application, a method for determining the location of the point of interest based on the device type tag is provided, and by the method, the location of the point of interest of the IoT device can be optimized and the reasonability of the location of the point of interest can be improved by combining the device type tag and a predefined article placement strategy.

Optionally, on the basis of the embodiment corresponding to fig. 3, in another optional embodiment provided in the embodiment of the present application, the method may further include:

in a first period, the server receives second device association information sent by a second bluetooth gateway, wherein the second device association information includes an identifier of the user terminal, identifiers of P bluetooth beacons and P pieces of signal strength information, the signal strength information in the P pieces of signal strength information is used for indicating the user terminal to receive the signal strength of the bluetooth beacon, and P is an integer greater than or equal to 1;

the server generates a second device mapping relation corresponding to the first period according to the second device association information, wherein the second device mapping relation comprises association relations among three Bluetooth beacons from the P Bluetooth beacons, the user terminal and a second Bluetooth gateway;

the server determines the position information of the user terminal in the electronic map according to the mapping relation of the second equipment corresponding to the first period;

after the server updates the map data of the electronic map according to the first point of interest position, the method may further include:

and if the map display instruction sent by the user terminal is received in the first period, the server responds to the map display instruction and sends the map data of the electronic map to the user terminal according to the position information of the user terminal in the electronic map so that the user terminal can display the map data of the electronic map.

In this embodiment, a manner of feeding back map data to a user terminal is described. In the first period, the second bluetooth gateway may actively report the second device association information to the server, or the server actively sends a request to the second bluetooth gateway, and the second bluetooth gateway responds to the request and then reports the second device association information to the server. The second period represents a period, for example, the first period is 1 second, 10 seconds, or 1 minute, and the like, which is not limited herein. In addition, the second bluetooth gateway and the first bluetooth gateway may be the same bluetooth gateway or different bluetooth gateways.

Similarly, the second device association information also includes two parts of information, one part is beacon information, the beacon information includes P bluetooth beacon identifiers and P signal strength information, the other part is user terminal information, and the user terminal information includes the user terminal identifier. Specifically, the identifier of the bluetooth beacon may be a MAC address of the bluetooth beacon, a UUID of the bluetooth beacon, an equipment serial number of the bluetooth beacon, or other identifiers that can uniquely indicate the bluetooth beacon. The identifier of the ue may be a MAC address of the ue, a UUID of the ue, a device serial number of the ue, or other identifier that can uniquely indicate the ue. The signal strength information may be RSSI, and each signal strength information represents the signal strength of a bluetooth beacon received by the user terminal.

In an implementation manner, for convenience of understanding, please refer to fig. 13, where fig. 13 is a schematic diagram of a second device mapping relationship in this embodiment, as shown in the figure, a server generates a network topology structure diagram based on second device association information, where the network topology structure diagram may be a DAG, where the second device mapping relationship may be represented as the DAG shown in fig. 13, a bluetooth beacon is a node with an access of 0, a topology structure diagram is constructed for bluetooth gateways, each bluetooth gateway and a beacon group managed by the bluetooth gateway form a DAG, and finally, device nodes are added to the whole DAG, so as to construct the topology structure diagram of the whole electronic map. Based on this, the information of the user terminal can be acquired from any node access.

In another implementation, the second device mapping relationship may be represented as a generated device mapping table, as shown in table 4, where table 4 is an illustration of the second device mapping relationship.

TABLE 4

As can be seen from table 4, the user terminal can be connected to three bluetooth beacons, and the user terminal communicates with one bluetooth gateway. The server can find a downstream node through the Bluetooth gateway C, namely, the Bluetooth gateway A is obtained, then a downstream node user terminal is found based on the Bluetooth gateway A, finally, the Bluetooth beacon connected with the user terminal in the current period is determined, and if the Bluetooth beacon connected with the user terminal changes, the mapping relation of the second device can be updated.

The server can generate a first device mapping relation based on the first device association information and generate a second device mapping relation based on the second device association information, and the Bluetooth beacon and the Bluetooth gateway are shared, so that the first device mapping relation and the second device mapping relation can be fused together. Taking the first device mapping relationship shown in fig. 4 and the second device mapping relationship shown in fig. 13 as an example, please refer to fig. 14, where fig. 14 is a schematic diagram of the device mapping relationship in the embodiment of the present application, as shown in the figure, after the first device mapping relationship and the second device mapping relationship are fused, an overall relationship is obtained, and the server only needs to maintain a common device mapping relationship.

And the server determines the coordinate position of the user terminal by adopting a Bluetooth indoor positioning technology and indoor position calculation according to the mapping relation of the second equipment acquired in the first period, so that the coordinate position can be determined as the position information of the user terminal in the electronic map. If the map display instruction sent by the user terminal is received in the first period, the server responds to the map display instruction and sends the map data of the electronic map to the user terminal according to the position information of the user terminal in the electronic map so that the user terminal can display the map data of the electronic map, namely the user terminal can display the current position of the user terminal and the positions of interest points of all peripheral IoT devices through the electronic map application.

Secondly, in the embodiment of the application, a way of feeding back map data to the user terminal is provided, and by the way, the user terminal is positioned in real time, and the current position of the user terminal is accurately judged, so that the server can send more accurate map data to the user terminal.

Based on this, the server responds to the interoperation instruction for the first point of interest location, and then obtains the device description information and the point of interest description information of the IoT device from the first device association information, where the IoT device is the IoT device corresponding to the first point of interest location. And finally, the server sends the equipment description information and the interest point description information of the Internet of things equipment to the user terminal, and the user terminal displays the equipment description information and the interest point description information of the Internet of things equipment to the user.

In the embodiment of the application, a mode for feeding back the relevant information of the point of interest in combination with user interaction operation is provided, and through the above mode, interaction between the user and the point of interest can be realized, the online working state of the point of interest corresponding to the IoT device can be sensed in real time, and more information amount and convenience are brought to the work and life of the user in the indoor space. However, the currently adopted interest point labeling method can only describe a static scene, that is, the interest points labeled in the map application cannot be moved, and the user cannot interact with the interest points by using the terminal device, so that the method has great limitation.

In one implementation, the server generates a network topology graph based on the third device association information, where the network topology graph may be a DAG, and the third device mapping relationship may be expressed as a DAG. In another implementation, the third device mapping relationship may be represented as a generated device mapping table.

The server determines the coordinate position of the IoT device by using a bluetooth indoor positioning technology according to the third device mapping relationship obtained in the second period, and then may determine the coordinate position as a second point of interest of the IoT device in the electronic map.

And the server updates the map data of the electronic map according to the acquired second point of interest position, wherein the second point of interest position represents the point of interest position of the IoT equipment. The update may be to move the native location of the IoT device, e.g., to move the first point of interest location to the second point of interest location.

Further, in the embodiment of the application, a method for dynamically updating map data is provided, by which, in each period, a point of interest of an internet of things device can be marked in an electronic map, and the map data is updated according to the point of interest, so that a user can perceive more point of interest information, and meanwhile, the update frequency of the point of interest position is faster and more accurate.
