Detailed Description
The person posture judging method and system of the present invention will be described in detail with reference to the accompanying drawings for explaining and explaining the scope of the present invention.
The invention relates to a personnel posture judging method, which comprises a running and walking state judging step, a stair ascending and stair descending posture judging step, a lying posture judging step or any combination of the steps; the steps required are selected according to the actual requirements (e.g. other systems equipped), and the present embodiment preferably includes all of the steps described above. Besides the development of rescue activities, it is also very important to prevent the life safety of the rescuers during the development process, and when the rescue actions are more urgent and the field environment is more complex, the rescuers are difficult to communicate with the background by voice, so that other information of the firefighters needs to be obtained in time to help the command background to judge the actual situation. In an actual rescue site, firefighters perform different actions according to the actual situation of the site, such as walking slowly when the ground is uneven, hearing a call for help to run quickly, lying on the ground to avoid being blocked by an obstacle at a normal height, or lying on the ground without consciousness due to being injured by poison gas or dropped objects on the site, and the like. In the method, the posture of the rescue personnel or the detected object is judged by accurately judging the posture of the rescue personnel, the actual condition of the rescue personnel is obtained by combining other information, and the command background can reasonably command the on-site rescue personnel according to the information and ensure the life safety of the on-site rescue personnel.
The running and walking state judging step comprises the following steps:
as shown in fig. 1, 1a, detecting real-time horizontal acceleration of a measured object;
collecting data of real-time horizontal acceleration changing along with time to obtain data of real-time speed changing along with time, and collecting all time intervals of which the real-time speeds of two adjacent times are zero;
1c, judging whether the state of the object to be measured is running or walking according to the size of the time interval; or
Detecting a horizontal acceleration of the object to be measured, 1 a', as shown in fig. 2;
1c, judging whether the state of the measured object is running or walking according to the magnitude of the real-time horizontal acceleration;
for walking and running, it is generally necessary to determine the state of the subject moving on a horizontal ground. Generally, walking is a controlled situation, and running may be an emergency situation. And calculating the data of the real-time speed changing along with the time through the relation between the acceleration and the time by using the real-time horizontal acceleration obtained by detection and combining the time. When a person walks, the foot can repeatedly step on the ground, the process of lifting the foot and stepping on the ground is carried out, the horizontal real-time speed when the person steps on the ground is zero, so the time interval of zero real-time speed of two adjacent times is acquired as the time for stepping on one step, the walking speed is slower as the time interval is longer, and the data can be used for judging whether the object to be tested walks or runs.
The inventor conducts experimental statistics, the average value of time intervals within a period of time (for example, 10 seconds) can better reflect the stage speed, the average value of the judged time intervals is set to be 0.02 seconds, when the average value is greater than the value, the measured object is judged to be running, otherwise, the measured object is judged to be walking. When walking or running is judged, the aim can be achieved by judging the magnitude of the acceleration, and in the embodiment, the real-time horizontal acceleration is more than 1.3m/s2If the user runs, the user walks, otherwise, the user walks.
As shown in fig. 2, the step of determining the postures of ascending and descending stairs comprises:
detecting real-time vertical acceleration of a positioning object;
2b, acquiring real-time data of the change of the vertical acceleration along with time, and judging that the motion state of the object to be measured is ascending or descending when the vertical acceleration changes periodically along with time;
the main characteristic of going upstairs and downstairs is the displacement in the numerical direction, and similar to the principle of judging walking and running on the horizontal plane, when a human body goes upstairs and downstairs step by step, the real-time acceleration can generate periodic change along with lifting and dropping feet, so that whether the detected object goes upstairs or downstairs is judged by judging whether the real-time vertical acceleration has periodic change. In the vertical reverse direction, the acceleration may be upward or downward, and when the vertical acceleration is upward, the measured object is judged to go upstairs; and when the vertical acceleration is downward, judging that the detected object is going upstairs.
As shown in fig. 3, the lying posture determining step includes:
detecting the angle of the measured object relative to the three-dimensional space of a horizontal plane;
and 3b, setting a reference direction on a horizontal plane, and judging whether the lying state is supine, lateral or prone according to the angle of the measured object relative to the three-dimensional space of the reference direction.
When the tested object lies on the ground for some reasons, the tested object is difficult to be accurately detected in the traditional detection system, the invention can accurately judge the lying posture of a person by detecting the angle of the tested object relative to the three-dimensional space of a horizontal plane, and further can more accurately judge the field condition and make more accurate command.
In order to be closer to and more conventional than a general use mode, in the lying posture judging step, an angle of a sole surface of the measured object in a three-dimensional space relative to a horizontal plane is detected, the reference direction preferably comprises a horizontal direction and a vertical direction, the horizontal direction comprises an x axis and a y axis which are perpendicular to each other, the positive direction of the x axis is the forward direction of the measured object, the vertical direction comprises a z axis which is perpendicular to the x axis and the y axis, and a right-hand space rectangular coordinate system is established by taking the x axis, the y axis and the z axis as references;
when the measured object takes the y axis as a rotating shaft and has an angle in a plane formed by the positive directions of the x axis and the Z axis, namely when the toe cap is inclined upwards, the supine position is judged; when the measured object takes the y axis as a rotating shaft and has an angle in a plane formed by the negative directions of the x axis and the Z axis, namely when the toe cap is inclined downwards, the prone position is judged; the preferred judgment method in this embodiment is as follows: when the y axis of the tested object is used as a rotating shaft, and in a plane formed by the x axis and the Z axis, the angle formed by the y axis and the Z axis is 50-130 degrees with the positive direction of the x axis, the tested object is judged to be supine; when the angle between the positive direction of the x axis is-50 degrees to-130 degrees, the patient is judged to be prone.
When the measured object takes the x axis as a rotating shaft and has an angle in a plane formed by the y axis and the Z axis, namely when the sole is laterally overturned, the lateral lying is judged. Preferably, the subject is determined to lie on the side when an angle formed by a plane formed by the y-axis and the Z-axis is 50 ° to 130 ° or-50 ° to 130 ° with the x-axis as the rotation axis.
