Background technique

Currently, wearable devices generally support Global Positioning System (GPS) positioning and network positioning. GPS positioning is to calculate the current position by receiving the signal of the satellite. It needs to be carried out in a relatively open place.

The network positioning is measured by the mobile terminal and the ground communication base station. The distance between the two is positioned, the positioning speed is fast, the power consumption is low, but the positioning accuracy is low. In the existing wearable device, the GPS positioning or the network positioning is generally selected by the user as the positioning mode of the wearable device. In this manner, the most suitable positioning mode cannot be automatically selected for the wearable device in different scenarios. For example, when the user is in the room, if the user selects the GPS positioning, the positioning accuracy is low due to the poor GPS signal in the room, and the power consumption is also high, which cannot meet the requirements of the user for positioning accuracy and power consumption. When the user selects the network positioning, although the power consumption is reduced, the positioning accuracy is also lowered, and the requirement for the positioning accuracy cannot be satisfied.

detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

Compared with smart phones, the battery capacity of wearable devices is generally small. Therefore, it is difficult for a wearable device to be positioned in a continuous positioning manner like a smart phone device, but a non-continuous positioning method is used for positioning, that is, It is said that the wearable device performs positioning at regular intervals. The existing wearable devices are generally selected by the user or set the positioning mode. This method cannot automatically consider the positioning accuracy of the wearable device in different scenarios and the energy consumption requirements of the wearable device to automatically select the most suitable positioning method. In the actual application process, there is a problem that the positioning accuracy cannot meet the requirements or the energy consumption is too high. Therefore, the embodiment of the present invention provides a positioning method, which can determine a scenario in which a user is currently located from a plurality of predefined scenarios. After determining a scenario in which the user is currently located, the positioning method can be selected. The positioning method suitable for adoption is used as the current positioning mode of the wearable device, and then the current positioning method is used to locate the user. Relying only on users in the prior art Compared with the positioning mode of the wearable device, the positioning mode suitable for the scenario can be selected by pre-defining a plurality of scenarios, so that the user can select a suitable positioning mode better. A method for determining a positioning method of a wearable device according to an embodiment of the present invention is described in detail below with reference to FIG. 1 to FIG.

FIG. 1 is a schematic flowchart of a positioning method according to an embodiment of the present invention. The method in FIG. 1 may be performed by a wearable device, or the positioning method may further determine, by other devices, the scene in which the wearable device is located according to the information reported by the wearable device, thereby making the scenario suitable for adoption. The positioning mode is used as the current positioning mode of the wearable device, and then the wearable device is notified, so that the wearable device locates the user by using the current positioning manner. The specific steps of the method are as follows:

110. The wearable device determines a scenario in which the user is currently located from a plurality of predefined scenarios, and different scenarios in the multiple scenarios are adapted to adopt different positioning modes.

The foregoing plurality of scenarios may include an indoor scene and an outdoor scene, wherein the indoor scene is adapted to adopt a network-based positioning manner, and the outdoor scene is adapted to adopt a satellite-based positioning manner. It should be understood that the outdoor scene herein may refer to a satellite signal better, suitable for satellite-based positioning, for example, the user is in the window of the building, and the satellite signal can meet the requirements, then this It can be considered that the user is in an outdoor scene and is suitable for satellite-based positioning. When the user is outside, for example, between two tall buildings, the satellite signal detected by the user is very poor. It is considered that the user is in an indoor scene and is suitable for satellite-based positioning. That is to say, the indoor scene and the outdoor scene here are a broad concept. Therefore, scenes without satellite signals or satellite signals can be regarded as indoor scenes, and scenes with better satellite signals can be regarded as outdoor scenes.

It should be understood that the indoor scene and the outdoor scene are only two specific scenarios given herein. In actual applications, multiple scenes (eg, the first scene, the second scene, and the third scene) may be pre-positioned as needed.

120. The wearable device determines a current positioning manner of the wearable device according to the current scenario of the user.

When the wearable device determines the scenario in which the user is currently located, the location mode suitable for the scenario may be used as the current location mode of the wearable device, for example, when the wearable device determines that the current location of the user is outdoor. In the case of a scene, the wearable device can determine the satellite-based positioning method as the current positioning mode of the wearable device.

130. The wearable device uses the current positioning method to locate the user.

Optionally, as an embodiment, the wearable device may determine, according to the detected satellite information, a scenario in which the user is currently located, when determining a scenario in which the user is currently located from a plurality of predefined scenarios, where The satellite information includes at least one of a number of satellites detected by the wearable device, a satellite signal strength, and a satellite position distribution. It should be understood that the satellite position distribution here refers to the position distribution of the satellite detected by the wearable device in the satellite positioning system coordinate system.

More specifically, when the satellite information detected by the wearable device is satellite information of the GPS, the position distribution of the satellite refers to the position distribution of the satellite detected by the wearable device in the WGS84 coordinate system, for example, the wearable device detects In the case of four GPS satellites, the four satellites are respectively distributed in which quadrants in the WGS84 coordinate system.

Optionally, the foregoing satellite information may be detected by the wearable device within a preset time, where the preset time may be a period of time after the wearable device receives the positioning request, and the length of the time period may be Set according to the actual situation.

Optionally, the wearable device may first initiate a search for satellite signals before the wearable device determines the scene in which the user is currently located according to the detected satellite information. Specifically, when the satellite information is GPS satellite information, the wearable device may start the GPS search star first, and then the wearable device may determine the current scene of the user according to the satellite information obtained by the GPS search star.

Optionally, as an embodiment, when the wearable device determines the current scenario of the user according to the detected satellite information, the following situations may be included:

When the wearable device satisfies at least one of the following conditions (1)-(3), it can be considered that the wearable device does not detect the satellite signal or the detected satellite signal is poor, and the user can be considered to be currently in the indoor scene. .

(1) The satellite signal is not detected by the wearable device;

(2) The satellite signal strength detected by the wearable device is less than a preset threshold;

(3) The number of detected satellites detected by the wearable device is less than a predetermined number;

(4) The satellite detected by the wearable device is distributed in one quadrant or two adjacent quadrants in the coordinate system of the satellite positioning system;

Specifically, for the above condition (2), the satellite signal strength detected by the wearable device is less than a preset threshold, which may be that the carrier power and the noise ratio of the satellite signal detected by the wearable device are greater than or equal to 20 db; 3) In the case that the number of satellites detected by the wearable device is less than 4, or the number of satellites detected by the wearable device is greater than or equal to 4, the number of satellites whose satellite signals satisfy the preset condition is less than 4; (4) If the wearable device detects 4 satellites and the satellite signals of the 4 satellites meet the preset conditions, the 4 satellites are distributed in two adjacent In the quadrant, for example, the four satellites are distributed in the first and second quadrants, the second and third quadrants, the third and fourth quadrants, the fourth and the first quadrant, and in this case, the positioning effect is better when satellite positioning is used. Poor, the user is still considered to be in an indoor scene.

Optionally, as an embodiment, when the wearable device determines the current scene of the user according to the detected satellite information, the wearable device may determine the relationship between the detected satellite signal strength and a preset threshold, and the detected satellite is in the The distribution in the coordinate system of the satellite positioning system determines the scene in which the user is currently located; specifically, the wearable device determines that the user is currently in an outdoor scene when the following conditions are met: (a) the wearable device detects N (N is The satellite signal strengths of integers greater than or equal to 4 are greater than a predetermined threshold; (b) N satellites are distributed in at least two non-adjacent quadrants in the coordinate system of the satellite positioning system.

For the above condition (b), when N=4, the four satellites are distributed at least in two non-adjacent quadrants in the coordinate system, for example, the four satellites are distributed in a three- or four-four quadrant in the coordinate system, or The four satellites are distributed in any three quadrants in the coordinate system, or the four satellites are respectively distributed in four quadrants in the coordinate system.

Optionally, as an embodiment, when the scene in which the wearable device is positioned once is an indoor scene, whether the wearable device satisfies condition 1 or condition 2 may be determined first, if the wearable device satisfies condition 1 and When one or all of the conditions 2 are triggered, the wearable device is triggered to determine the scene in which the user is currently located, and when these conditions are not met, the wearable device is not triggered to determine the scene in which the user is currently located.

Condition 1: The displacement of the user from the previous positioning to the current positioning is greater than the preset displacement;

Condition 2: The current cell ID of the user is different from each cell ID in the historical cell ID saved by the wearable device.

For condition 1, the displacement of the user's movement can be recorded by the acceleration sensor in the wearable device. If the displacement recorded by the acceleration sensor of the wearable device reaches a preset displacement (for example, 100 meters), the wearable device can be considered as the last time. After the positioning is completed, the distance moved is large, and it is necessary to judge whether the wearable device is still in the indoor scene.

For condition 2, the wearable device can save the ID of the cell where the user is located, when the ID of the cell where the user is currently located is inconsistent with the predetermined number of cell IDs saved by the history of the wearable device (for example, the cell ID of the wearable device currently located) If the four cell IDs stored in the history are inconsistent, it can be considered that the wearable device has a certain mobility after the last positioning is completed, and may move from the previous cell to another cell. In this case, it is also required whether the wearable device is still in the The indoor scene is judged.

Optionally, as an embodiment, when the wearable device does not satisfy the above condition 1, the distance that the wearable device moves after the last positioning is completed may be considered to be small, and the wearable device may be considered to be still in the indoor scene.

FIG. 2 is a schematic flowchart of a positioning method according to an embodiment of the present invention. FIG. 2 shows how the user can trigger the wearable device to determine the current scene of the user when the scene where the user is located last time is an indoor scene. The specific process is as follows:

201. Determine an accumulated displacement of the acceleration sensor. The acceleration sensor in the wearable device can record the displacement of the wearable device, and the acceleration sensor can record the displacement of the user from the previous positioning to the current positioning, and then compare the relationship between the displacement of the user and the preset displacement.

202. Determine whether the cumulative displacement of the user movement reaches 100 meters. It should be understood that the preset displacement here is 100 meters, and in practice, the preset displacement can be flexibly set as needed, for example, 80 meters, 120 meters, and the like.

203. If the cumulative displacement of the user movement reaches or exceeds 100 meters, then the wearable is triggered. The device starts the GPS search star, and then the wearable device re-judges the scene in which the user is located based on the detected satellite information.

If, in step 202, the cumulative displacement recorded by the acceleration sensor does not reach 100 meters, then the displacement of the wearable device from the previous positioning to the current movement may be considered to be small, and the wearable device may still be considered to be in the indoor scene, and then Trigger the wearable device to re-evaluate the scene in which the user is located.

FIG. 3 is a schematic flowchart of a positioning method according to an embodiment of the present invention. Similar to the method shown in FIG. 2, FIG. 3 shows how the user can trigger the wearable device to determine the current scene of the user when the scene where the user was located last time is an indoor scene. The specific process is as follows:

301. Determine a cell ID where the user is currently located. Specifically, after determining the current cell ID, it may be compared whether the current cell ID and the historical cell ID are the same. For example, if there are 4 historical cell IDs, then the current cell ID and the 4 historical cells are compared. Is the ID the same? It should be understood that the historical cell ID here is the ID of the cell in which the wearable device is located within a certain time.

302. Determine whether the current cell ID is consistent with the four cell IDs saved in the history.

303. If the current cell ID is inconsistent with the four cell IDs saved in the history, then the GPS search star is started.

Specifically, when there are four cell IDs stored in the history, if the current cell ID is inconsistent with the IDs of the four cells, the displacement of the user may be considered to be large, and the wearable device may be triggered to restart the GPS. Searching for stars and judging the scene in which the wearable device is located based on the detected satellite information.

FIG. 4 is a schematic flowchart of a positioning method according to an embodiment of the present invention. Figure 4 shows the entire process of the wearable device from positioning requirements to determining the positioning method. The specific steps are as follows:

401, start. The beginning of this can be thought of as the wearable device receiving the positioning request and preparing to start positioning.

402, start GPS search star. GPS search star is the basis of GPS positioning. Only when GPS signal is found can the GPS signal be judged to determine whether GPS positioning or network positioning is used as the positioning method of the current positioning of the wearable device.

403. Determine whether the number of GPS satellites/GPS satellite signals/GPS satellites searched by the wearable device is lower than a preset threshold.

404. If the condition in step 403 meets the preset condition, set the network positioning or the base station positioning to the current positioning mode of the wearable device.

Specifically, when the number of satellites searched by the wearable device is less than 4, the GPS signal may be considered to be poor, and the network positioning or base station positioning may be set as the current positioning mode of the wearable device. When the wearable device searches for the number of satellites whose carrier power and noise ratio is greater than or equal to 20 db is less than 4, the GPS signal is considered to be weak, and the network positioning or base station positioning is set as the current positioning mode of the wearable device. When the wearable device searches for a number of satellites with a carrier power and noise ratio greater than or equal to 20 db greater than or equal to 4, but the distribution of these satellites is a half-day distribution, the positioning environment is considered to be poor, and the network positioning or base station positioning is still set to The current positioning method of the wearable device.

405. After determining, in step 404, that the network positioning or the base station positioning is set as the positioning mode of the wearable device, if the positioning needs to be performed again after a period of time, it may first determine whether the sensor cumulative displacement/cell ID change satisfies the condition. .

Specifically, for step 405, the positioning mode selected by the user during the last positioning is network positioning or base station positioning, that is, the wearable device is in an indoor scene when the previous positioning is performed. When the last positioning is completed and the next positioning is required, the method shown in Figure 3 can be used to determine whether it needs to be touched. The wearable device determines the scene in which the user is currently located to make a judgment.

406. If the sensor cumulative displacement/cell ID change satisfies the condition, then the GPS search star is started, and the wearable device re-evaluates the scene in which the user is located.

407. After starting the GPS search star, determine whether the number/distribution/signal strength of the GPS satellite is higher than the threshold.

408. If the number of GPS satellites/distribution/signal strength is higher than a threshold, then the GPS positioning is set to the positioning mode of the wearable device.

409. Perform positioning according to the determined positioning manner.

In addition, in step 403, if the number of GPS satellites/distribution/signal strength is not lower than the threshold, it can be considered that the GPS signal at this time is strong, and then step 408 can be directly executed, that is, the GPS satellites are determined. When the number/distribution/signal strength is not lower than the threshold, the GPS positioning is directly set to the positioning mode of the wearable device.

In step 407, if the number of GPS satellites/distribution/signal strength is not higher than the threshold, it can be considered that the GPS signal is weak at this time, and step 404 needs to be performed, that is, when it is determined that the GPS signal is weak. The network positioning or base station positioning can be set to the current positioning mode of the wearable device.

It should be understood that the positioning method of the embodiment of the present invention is implemented by an independent module, and the positioning method of the embodiment of the present invention can be applied to the upper layer of the wearable device and the lower layer positioning module. A logical adaptation layer is implemented between them.
