In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a positioning method of a wearable device according to an embodiment of the present invention. The method comprises the following steps:
s110: acquiring the current motion state and the current speed of a user;
it should be noted that, in the process of positioning the position and the motion trajectory of the user, the current motion state and the current speed of the user are obtained, and specifically, the current motion state of the user is determined according to the current acceleration by acquiring the current acceleration of the user, and the current speed of the user is obtained by analyzing the current acceleration. The current acceleration can be acquired by an acceleration sensor (Gsensor) arranged on the wearable device.
Specifically, the exercise state includes a stationary state and a non-stationary state, wherein the non-stationary state is also an exercise state, and specifically may include riding, walking, running, riding and the like.
S120: calculating the current positioning period of the GPS according to the preset positioning distance and the current speed;
specifically, the positioning distance can be preset, and the current positioning period can be calculated according to the preset positioning distance and the current speed, wherein the preset positioning distance can reflect the positioning accuracy, and when the current speed is different, the corresponding current positioning periods are different, so that the positioning period of the GPS can be dynamically adjusted according to the actual motion condition of the user, and the positioning accuracy is ensured.
In addition, different motion states may correspond to different preset distances, that is, the preset distances may be determined according to the current motion state, for example, if the current motion state is walking, the preset distances may be 5m or 10m, and if the current motion state is riding, the preset distances may be 100m or 200m, and the like.
S130: judging whether the current motion state is a non-static state, if so, entering S140;
s140: and controlling the GPS to position the current position of the user according to the current positioning period.
It should be noted that, when the current motion state of the user is a non-stationary state, it indicates that the user is currently moving, and at this time, the GPS may be controlled to locate the current position of the user according to the calculated current location cycle, and the current position information of the user is recorded.
Therefore, the current positioning period of the GPS can be obtained according to the current speed and the preset positioning distance of the user, when the current motion state of the user is in a non-static state, the GPS is controlled to position the current position of the user according to the current positioning period, the obtained current positioning periods are different when the current speed is different, the positioning period of the GPS is dynamically adjusted according to the current speed of the user, the working time of the GPS is reduced on the basis of ensuring the positioning accuracy, the power consumption of the GPS is reduced, and the cruising performance of equipment is improved.
The embodiment of the invention discloses another positioning method of wearable equipment, and compared with the previous embodiment, the embodiment further describes and optimizes the technical scheme, and please refer to fig. 2. The method comprises the following specific steps:
s200: acquiring current acceleration information of a user;
s210: obtaining the current motion state and the current speed of the user according to the current acceleration information, and recording the current motion state and the current time corresponding to the current motion state into a motion state file;
specifically, the process of acquiring the current motion state and the current speed of the user in S110 in the above embodiment may be specifically implemented by S200 and S210 in this embodiment, where current acceleration information of the user may be acquired by an acceleration sensor (Gsensor), and specifically, after a preset time duration is continuously acquired, each acceleration data within the time duration is obtained, that is, the current acceleration information may include a plurality of acceleration data, and then the current motion state and the current speed of the user are obtained after analyzing the current acceleration information.
It should be noted that, not only can the current motion state and the current speed of the user be accurately determined through the current acceleration information, but also the power consumption of the acceleration sensor is far lower than that of the GPS, so that the current acceleration information of the user is collected by the acceleration sensor, which is beneficial to reducing the power consumption of the device.
In addition, after the current motion state of the user is determined, the current motion state and the current time corresponding to the current motion state can be recorded into a motion state file established in advance.
S220: calculating the current positioning period of the GPS according to the preset positioning distance and the current speed;
s230: judging whether the current motion state is a static state, if so, entering S240; if not, entering S250;
s240: judging whether the last motion state of the user is a static state or not, and if not, entering S260;
s260: and controlling the GPS to position the current position of the user, and controlling the GPS to enter a non-working mode after the positioning is successful.
It should be noted that, in order to accurately locate the position of the user and improve the positioning accuracy, after determining the current motion state of the user, the last motion state of the user may be obtained from the motion state file, where the last motion state of the user refers to a motion state recorded in the motion state file and corresponding to a time adjacent to the current motion time. When the current motion state of the user is a static state and the last motion state of the user is a non-static state, the user is from motion to static, the GPS can be directly controlled to position the current position of the user, and the current position information can be displayed to the user after the positioning is finished. In addition, after the GPS positioning is finished for the current position positioning, the GPS is controlled to enter a non-working mode, so that the power consumption is saved.
It should be noted that when the current motion state of the user is a stationary state and the last motion state of the user is also a stationary state, it may be considered that the user is not moving, and at this time, the GPS is controlled to maintain the non-operating state.
Further, the process of controlling the GPS to locate the position of the user according to the current location cycle in S140 may specifically include the following steps:
s250: judging whether the last motion state of the user is a static state, if so, entering S270; if not, the process goes to S280;
s270: controlling a GPS to position the current position of a user, and controlling a timer to start timing according to the current positioning period; wherein, the GPS is in a non-working mode in the timing process of the timer;
specifically, when the current motion state of the user is a non-stationary state and the last motion state of the user is a stationary state, it indicates that the user is moving from stationary, and at this time, the GPS may be controlled to locate the current position of the user, obtain the current position information, and simultaneously control the timer to start timing according to the calculated current location period.
The GPS is in a non-working mode in the timing process of the timer, and the GPS is controlled to position the position of the user until the timing duration reaches the size of the current positioning period; or at the moment, obtaining a new motion state of the user, if the new motion state is a static state, immediately controlling the GPS to position the current position of the user, stopping timing by the timer, resetting the timer, and after the positioning is finished, controlling the GPS to enter a non-working mode, if the new motion state is a non-static state, calculating a new positioning period according to the motion speed corresponding to the non-static state, and if the timing duration of the timer does not reach the duration corresponding to the calculated current positioning period, determining whether the timing duration of the timer reaches the duration corresponding to the new positioning period, if so, immediately controlling the GPS to position the position of the user, and if not, controlling the timer to continue timing according to the new positioning period.
S280: judging whether the current timing duration of the timer is greater than or equal to the current positioning period, if so, entering S290; if not, the process goes to S291;
s290: and controlling the GPS to position the current position of the user, and controlling the timer to restart timing according to the current positioning period.
It should be noted that, when the current motion state of the user is a non-stationary state and the last motion state of the user is also a non-stationary state, it is indicated that the user has moved from the last positioning to the current state, and since the last motion state of the user is a non-stationary state, it can be determined that the timer is in the timing process, at this time, the current timing duration of the timer can be compared with the current positioning period calculated this time, and if the current timing duration reaches the current positioning period, the GPS is controlled to position the current position of the user, and the timer is controlled to restart timing according to the current positioning period;
s291: and controlling the timer to keep timing according to the current positioning period.
Specifically, if the current timing duration of the timer does not reach the size of the current positioning period calculated this time, the timer is controlled to continue timing according to the current positioning period, so that the positioning period of the GPS is dynamically adjusted.
In addition, it should be noted that the motion state information recorded in the file may also be cleared after the user is in a static state for a preset duration, so as to reduce the occupancy rate of the device memory and save the storage space.
Further, the step S260 of controlling the GPS to enter the non-operating mode after the positioning is successful may specifically be:
and controlling the GPS to enter a sleep mode after the positioning is successful.
The non-working mode of the GPS in the embodiment is a sleep mode, the sleep mode is low in power consumption, and the GPS can be activated quickly when the GPS is controlled to position the user, so that the positioning efficiency is improved.
Further, after controlling the GPS to locate the current position of the user in any one of the steps S260, S270, and S290, the method may further include:
and acquiring the current position information of the user and displaying the current position information.
Specifically, after the current position of the user is located, the current position information is acquired, the current position information is displayed for the user, the current position information can be displayed through a display device on the wearable device, the current position information can be sent to a terminal device which is in wireless connection with the wearable device to be displayed so that the user can check the current position information at any time, and the current position information can be uploaded to a cloud end to be stored.
