Detailed ways

The technical solution of the present invention will be further described below with reference to FIG. 1 and FIG. 2 and through specific implementation methods.

Embodiment one

FIG. 1 is a flow chart of a method for replaying historical tracks based on motion states according to Embodiment 1 of the present invention.

A historical trajectory playback method based on motion state, comprising:

Step 110, collecting location information through a positioning device, and calculating location track information according to the location information;

Step 120, collecting motion information through a motion sensor, and calculating motion type information and corresponding motion speed information according to the motion information;

Step 130, uploading the position track information, motion type information and motion speed information to the server, and the server obtains the historical track according to the position track information, motion type information, motion speed information and preset comparison parameters;

Step 140, playback the historical track.

In this embodiment, through the comprehensive use of the positioning device and the motion sensor, the historical motion trajectory of the child is obtained, and played back through the server or mobile terminal, so that the parents can fully understand the child's motion status, and timely discover the previous danger or danger. Bad behavior habits, guide children to correct behavior, and reduce children's danger.

In this embodiment, the positioning device can record the child's walking track for a day, where he has been, how long he has stayed, relative displacement speed, etc., wherein the detailed speed cannot be obtained, such as small-scale circle chasing cannot be accurately obtained, reflected is the relative displacement velocity.

In this embodiment, the motion information includes: motion amplitude, motion frequency, and motion acceleration. Based on these information, specific motion types and small-scale speed information can be analyzed.

In this embodiment, the preset comparison parameters include: speed and movement characteristics of the transportation mode, and the transportation mode includes: rest, walking, running, cycling, car or bus.

In this embodiment, the location track information, motion type information, and motion speed information are integrated, combined with the speed and motion characteristics of the current main modes of transportation, to analyze the different motion types of children, and then use the graphical method to play back the historical trajectory During the process, it will be shown to parents. Among them, resting, walking and running can be distinguished by analyzing the trajectory, range, frequency and local acceleration of the motion sensor. The frequency of walking is low, and the frequency of running is high, and the acceleration is also different. There are relatively mature algorithms; there are mainly differences in speed between cars and bicycles, and the amplitude of motion sensors is inconsistent with walking and running, which can also be distinguished by algorithms.

In this embodiment, the step 140 includes:

performing playback of the historical track on the server; or,

The historical track is sent to the mobile terminal, and the historical track is played back on the mobile terminal.

In this embodiment, when the server or mobile terminal performs track playback, the type of traffic and the specific movement type of children at each point can be obtained comprehensively according to the positioning information and motion sensor information, and the simple map can be used on the map. When watching the track playback, parents can clearly know the behavior of children on each road section. When children are found running across the road, or staying or chasing too much on the road when crossing the road, they will be reminded in time. Children pay attention to safety, and stop doing these dangerous behaviors when crossing the road. You can also find out the amount of children's daily exercise according to the trajectory, and remind children in time not to exercise excessively or encourage more exercise.
