[0086] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0087] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0088] In order to solve the technical problem that the manual room division and device positioning in the prior art requires a lot of manpower and is very inefficient, the present application provides a device positioning method that can realize intelligent room division of the target place and intelligent positioning of the device in the target place. The whole process does not require manual operation, thereby saving labor costs and improving the efficiency of whole-house smart appliance configuration.

[0089] Figure 1 A flow chart of an embodiment of a device positioning method provided in an embodiment of the present application.

[0090] like Figure 1 As shown, the method comprises the following steps:

[0091] Step 101, obtaining an initial floor plan of a target location;

[0092] Target places refer to places where whole-house smart appliances need to be configured, such as residences, office buildings, shopping malls, etc.

[0093] In the embodiment of the present application, a scanning device with a patrol scanning function (such as a sweeping robot) can be used to patrol and scan, walk on the ground, and record the activity trajectory to obtain the initial floor plan of the target place. The floor plan takes the starting point of the scanning device as the origin and records the initial room division of the target place scanned by the scanning device. In other words, the location of each room in the initial floor plan is the coordinate recorded with the starting point of the scanning device as the origin. The coordinates mentioned here refer to the screen coordinates when the floor plan is displayed on the terminal screen.

[0094] Step 102: Divide the target place into areas based on the initial floor plan to obtain corresponding room division data, wherein the room division data includes at least one room and the room location of each room.

[0095] Room division data refers to data obtained by dividing the target place into regions according to the actual room conditions in the target place, including at least one room and the room location of each room.

[0096] In an embodiment of the present application, the above-mentioned initial floor plan can be further processed to achieve accurate division of the room conditions in the target place and obtain corresponding room division data. In this way, the room division data can be used to prepare for subsequent device positioning, so as to facilitate the corresponding marking of each device in the target place and the room where it is located.

[0097] As for how to divide the target place into areas based on the initial floor plan to obtain corresponding room division data, it will be described in detail through the following embodiments and will not be described in detail here.

[0098] Step 103: Determine the device location corresponding to each device in the target location.

[0099] The device location refers to the location coordinates of the corresponding device in the target location.

[0100] In actual applications, a target location is equipped with multiple smart devices. For example, when the target location is a residence, it may include smart devices such as a television, a refrigerator, a washing machine, and an air conditioner; when the target location is an office, it may include smart devices such as a projector, a computer, a refrigerator, and an air conditioner, and so on.

[0101] In the embodiment of the present application, the location coordinates of each device in the target location can be intelligently determined through the Bluetooth function of the mobile device (such as a mobile phone) and the Bluetooth function of each device in the target location.

[0102] As for how to determine the device position corresponding to each device in the target location, it will be described in detail through the embodiments below and will not be described in detail here.

[0103] Step 104: For each device, based on the device location of the device and the room location of each room, determine a target room where the device is located in at least one room.

[0104] In an embodiment of the present application, after determining the room location of each room in the target place and the device location of each device, the device can be matched with the room through the room location and the device location to determine the target room where each device is located.

[0105] In the application, a unique room name can be set for each room. For each device, after determining the target room corresponding to the device, the room name of the target room is assigned to the device, thereby completing the marking of the room area information of the device.

[0106] For example, if the device A is located in the room location area of ​​room 1, then room 1 can be determined as the target room where device A is located. Therefore, the room name "1" of room 1 is assigned to device A.

[0107] The technical solution provided by the embodiment of the present application first obtains the initial floor plan of the target place, and divides the target place into areas based on the initial floor plan to obtain corresponding room division data, wherein the room division data includes at least one room and the room position of each room, then determines the device position corresponding to each device in the target place, and finally, for each device, based on the device position of the device and the room position of each room, determines the target room where the device is located in at least one room. Thus, intelligent room division of the target place and intelligent positioning of the devices in the target place are realized, and the whole process does not require manual operation, thereby saving labor costs and improving the efficiency of whole-house smart home appliance configuration.

[0108] Figure 2 A flowchart of an embodiment of the present application is provided for dividing the target place into areas based on the initial floor plan to obtain corresponding room division data. Figure 2 The process shown in Figure 1 Based on the process shown, the following steps are included:

[0109] Step 201: Obtain at least one dividing line input by the user for the initial floor plan.

[0110] Step 202: based on at least one of the dividing lines, divide at least one of the first room areas in the initial floor plan to obtain a corresponding second room area.

[0111] For ease of understanding, step 201 and step 202 are described in a unified manner as follows:

[0112] The above initial floor plan contains the first room area corresponding to each room. Figure 3 As shown, it is an example of an initial floor plan, wherein A1 to A7 are areas corresponding to 7 rooms scanned by a scanning device.

[0113] In the application, the first room area of ​​each room scanned by the scanning device may not match the actual area. Therefore, in the embodiment of the present application, the user can input a dividing line for further dividing the corresponding first room area on the initial floor plan according to the actual situation, such as Figure 3 The dotted line shown in FIG. 8 can be used to divide the first room area A1 into two upper and lower second room areas.

[0114] Specifically, step 202 may include the following steps:

[0115] Step A1: setting a unique area color for each first room area on the initial floor plan, and setting a boundary color for the area boundary of each first room area, wherein the boundary color is different from the area color of each first room area.

[0116] For example, you can Figure 3 The A1 area in the example is set to green, the A2 area is set to purple, the A3 area is set to blue, and so on, different colors are set for A1-A7. The area boundaries of each area can be set to a unified color that is different from the area colors of each area, such as black.

[0117] It can be understood that the area color and boundary color set for each room area refers to the color displayed when the floor plan is displayed on the terminal screen.

[0118] Step A2: For each dividing line, based on the colors of each point on the dividing line, the area color of each first room area and the boundary color, determine the target room area where the dividing line is located in at least one of the first room areas, as well as the two intersection points of the dividing line and the target room area.

[0119] Specifically, step A2 may include the following steps: performing calculations based on the starting point coordinates and the ending point coordinates of the dividing line to obtain a second slope formula corresponding to the dividing line, traversing the horizontal coordinate based on the second slope formula to obtain multiple reference points on the dividing line, determining at least one color value corresponding to the multiple reference points and the number of reference points corresponding to each color value, and determining the color value with the largest number of corresponding values ​​as the target color value, determining the first room area whose corresponding area color is consistent with the target color value as the target room area, and determining the reference point whose corresponding color value is consistent with the boundary color as the two intersection points of the dividing line and the target room area.

[0120] In this implementation, first obtain the horizontal and vertical coordinate values ​​of the starting point X1 (x1, y1) and the end point X2 (x2, y2) of the dividing line, substitute the coordinates of these two points into the slope formula y=ax+b, calculate, and obtain a=a1, b=b1, thereby obtaining the second slope formula y=a1x+b1. Then, traverse the X value from 0, obtain its Y value, obtain the corresponding point, and determine the first room area where it is located (that is, the first room area with the same corresponding color value) according to the color value of the point on the initial floor plan. Similarly, traverse from X2 to 0 to determine the area where each point on the straight line is located. Then, the first room area where most of the length of the dividing line is located, that is, the area containing the most reference points, is determined as the corresponding target room area. For example, 90% of the reference points on the dividing line are located in area A1, and 10% of the points are located in area A2, then area A1 is determined to be the target room area. Finally, the reference points whose corresponding color values ​​are consistent with the boundary color are determined as the two intersection points of the dividing line and the target room area.

[0121] Step A3: Calculate based on the coordinates of the two intersection points to obtain a corresponding first slope formula.

[0122] Step A4: Divide the first room area into two second room areas based on the straight line corresponding to the first slope formula.

[0123] In this embodiment, after determining the two intersection points, the coordinates of the two points are substituted into the slope formula y=ax+b, and a=a2 and b=b2 are obtained, thereby obtaining the first slope formula y=a2x+b2. The straight line corresponding to the first slope formula is used to divide the first room area into two second room areas.

[0124] Figure 4 The figure shows an example of a target floor plan obtained after processing the initial floor plan. Figure 4 As shown, the area A1 is divided into two second room areas, area A11 and area A12, by a dividing straight line in the area A1.

[0125] It can be understood that, for the first room area that the user does not draw a straight line, the corresponding second room area is still itself.

[0126] Through this solution, users can further divide the initial floor plan according to the actual room conditions in the target place, so as to obtain more accurate division data.

[0127] Step 203: For each second room area, perform an area completion operation on the second room area to obtain a corresponding third room area.

[0128] Step 204: determine the target floor plan formed by all the third room areas as the room division data.

[0129] For ease of understanding, step 203 and step 204 are described uniformly below:

[0130] In an embodiment of the present application, step 203 may include the following steps: determining two target corner points from multiple corner points of the second room area, wherein the two target corner points are diagonal points of each other, constructing a rectangular area based on the two diagonal points, and performing a region completion operation on the second room area based on the rectangular area to obtain a corresponding third room area.

[0131] In this embodiment, for the room area with gaps scanned by the scanning device, a rectangular area can be delineated by two diagonal points (for example, the upper left corner point and the lower right corner point), and the rectangular area can be filled with the color corresponding to the room area to implement the filling operation on the room area to fill the missing area of ​​the room caused by the occupancy of the ground.

[0132] For example, Figure 3 The A1, A5, A6, and A7 areas shown in the figure are areas with gaps. For each area, a rectangular area is defined by its upper left corner and lower right corner to implement the area filling operation, and the following is obtained: Figure 4 Floor plan shown.

[0133] It can be understood that, for the second room area which is a rectangle itself, the filling step can be skipped, and the third room area corresponding to the second room area is itself.

[0134] Finally, the target floor plan formed by all the third room areas is determined as the room division data, thereby obtaining the room division data ultimately used for device positioning.

[0135] pass Figure 2 The process shown can first divide the corresponding room areas in the initial floor plan based on the dividing lines input by the user, so that the room division situation conforms to the actual situation of the target place, and then fill in the missing room areas caused by ground occupancy, so as to make the final room division data more accurate.

[0136] Figure 5 A flowchart of an embodiment of the present application for determining a device location corresponding to each device in the target location. Figure 5 The process shown in Figure 1 Based on the process shown, the following steps are included:

[0137] Step 501: obtaining the location coordinates of a preset terminal device in the target location;

[0138] Step 502: Activate the Bluetooth function of all devices in the target location;

[0139] Step 503: Control the terminal device to repeatedly perform the following steps until all devices are positioned: determine three unpositioned devices to be determined among all devices, receive Bluetooth signals of the three devices to be determined, and determine an angle between each device to be determined and the terminal device based on the Bluetooth signals, and detect the signal strength of each device to be determined relative to the terminal device;

[0140] Step 504: for each device to be determined, determine the device distance between the device to be determined and the terminal device based on the signal strength of the device to be determined;

[0141] Step 505: Substitute the location coordinates of the terminal device and the angles and device distances of the three devices to be determined relative to the terminal device into a trigonometric function to obtain the device location of each device to be determined in the target location.

[0142] For ease of understanding, steps 501 to 505 are described in a unified manner as follows:

[0143] The terminal device, generally a mobile terminal, is used to measure the distance and angle of each device in the target location relative to it, such as a mobile phone, tablet computer, etc.

[0144] In the embodiment of the present application, first, the terminal device can be placed at the starting point of the scanning device, so that the position coordinates of the terminal device can be directly determined as the origin coordinates (0, 0).

[0145] Then, all the smart devices that need to be located in the target location are powered on, and the Bluetooth function of each smart device is turned on to make it emit a Bluetooth hotspot. The terminal device receives the Bluetooth signals of three smart devices that have not been located (i.e., the devices to be determined) each time, and determines the angle of each smart device relative to the terminal device through the Bluetooth direction finding function, and calculates the distance between each smart device and the terminal device according to the strength of the device signal RSSI.

[0146] Next, for each smart device, the device distance (in meters) between the smart device and the terminal device is determined according to the signal strength of the smart device. Specifically, the signal strength of the device is substituted into the following formula to obtain the device distance between the device and the terminal device. The formula is as follows: L = 10 (A·RSSI+B) (Formula 1);

[0147] Where L is the device distance, RSSI is the signal strength, A is a constant related to the attenuation factor of signal propagation, and B is a constant related to the initial strength of the signal and the reference distance.

[0148] In applications, the A parameter is mainly related to the attenuation factor of signal propagation. For example, the signal will be attenuated due to factors such as obstacles. The B parameter is related to the initial strength of the signal and the reference distance. It includes the influence of factors such as the transmitting power and antenna gain of the transmitter on the signal strength at a specific reference distance.

[0149] Assuming that in the current environment, A=-59dBm / m, B=20dBm, and the signal strength RSSI of device B=-70, the device distance LB of device B relative to the terminal device is 10(-59·-70+20)≈10(4100)≈1.26×1040 meters.
