Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The embodiment of the invention provides a real-time capturing method for parameters of a motion tracking controller. The execution subject of the motion tracking controller parameter real-time capturing method includes, but is not limited to, at least one of the electronic devices of a server, a terminal, and the like, which can be configured to execute the method provided by the embodiment of the present invention. In other words, the motion tracking controller parameter real-time capturing method may be performed by software or hardware installed in a terminal device or a server device, and the software may be a blockchain platform. The server includes but is not limited to: the cloud server can be an independent server, or can be a cloud server providing basic cloud computing services such as cloud service, a cloud database, cloud computing, a cloud function, cloud storage, Network service, cloud communication, middleware service, domain name service, security service, a Content Delivery Network (CDN), a big data and artificial intelligence platform, and the like.
Referring to fig. 1, a schematic flow chart of a method for capturing parameters of a motion tracking controller in real time according to an embodiment of the present invention is shown. In an embodiment of the present invention, the method for capturing parameters of a motion tracking controller in real time includes:
and S1, starting a motion tracking controller pre-arranged in the moving object, wherein the motion tracking controller comprises a motion detector, a speed detector, a micro-mechanical gyroscope and an air bag detector.
It should be understood that the motion tracking controller is a control detection type instrument for detecting the motion state of a moving object in real time, and generally comprises a plurality of instruments.
The motion detector can be constructed by using a GPS (global positioning system), when the moving object moves, the corresponding position of the moving object must be changed, and the position of the moving object positioned by the GPS in the motion detector is correspondingly changed, so that the moving object can be detected. Similarly, the speed detector comprises a timer and a GPS positioning system, the GPS positioning system is used for calculating the movement distance of the object, and the movement speed of the object is calculated according to the timing result of the timer.
In the embodiment of the invention, the micromechanical gyroscope is also called an angular rate sensor, and is mainly used for measuring the azimuth angle of a moving object. The Azimuth angle is also called Azimuth angle (Az), and is mainly used for measuring the angle difference of the object, and in detail, the horizontal angle between a certain point and a north-pointing direction line is used as the horizontal angle between the clockwise direction and the object direction line.
In addition, it should be explained that an airbag detector, which is a passive safety protection system and detects whether an airbag is deployed, for example, during driving of a vehicle, is generally used only in moving objects, such as automobiles, etc., to which an airbag has been mounted.
And S2, when the current signal generated by the motion detector is received, the current signal is used for activating the speed detector to detect the real-time speed of the moving object.
It should be understood that the speed detector is required to cooperate with the movement speed of the object when the current signal generated by the movement detector is received, which indicates that the GPS positioning system in the movement detector detects the movement of the object.
In detail, referring to fig. 2, the detecting the real-time speed of the moving object by using the current signal to activate the speed detector includes:
s21, starting a GPS (global positioning system) and a timer which are arranged in the speed detector by the current signal;
s22, acquiring a first time and a second time from the timer;
s23, acquiring a first position of the moving object from the GPS positioning system according to the first time, and acquiring a second position of the moving object from the GPS positioning system according to the second time;
and S24, calculating the position difference value between the second position and the second position to obtain the position difference, and calculating to obtain the real-time speed by taking the position difference as a parameter of a pre-constructed speed calculation formula.
In the embodiment of the present invention, the calculating the real-time speed by using the position difference as a reference of a pre-constructed speed calculation formula includes:
wherein,
the difference in the position is represented by a difference in the position,
which is representative of the second time of day,
is representative of the first time at which the user is present,
representing the real-time speed.
And S3, when the real-time speed is zero, calculating the azimuth angle of the moving object by using the vibration signal transmitted by the micro-mechanical gyroscope, and calculating the stop state of the moving object by using the azimuth angle.
It is to be explained that the stop states include normal stop, rollover, and inversion. For example, if a vehicle traveling at a high speed is required to suddenly stop due to a sudden obstacle ahead, and thus the vehicle turns over, the stopped state of the vehicle is the rollover.
Further, the embodiment of the invention judges the stop state of the moving object according to the azimuth angle. In detail, referring to fig. 3, when the real-time speed is zero, calculating an azimuth angle of the moving object by using the vibration signal transmitted by the micro-mechanical gyroscope includes:
s31, when the real-time speed is zero, judging whether the speed of the real-time speed at the moment before is zero, and when the speed of the real-time speed at the moment before is not zero, generating a starting instruction of the micro-mechanical gyroscope;
it should be explained that when the real-time speed is zero, it indicates that the moving object has changed from the moving state to the stationary state, but in order to prevent the moving object from repeatedly calculating its azimuth angle in the stationary state, which results in resource waste, it is necessary to determine whether the speed of the real-time speed is zero at the moment before, when the speed of the real-time speed is not zero, a micro-mechanical gyroscope start instruction is generated, and when the speed of the real-time speed is still zero, it indicates that the moving object is already in the stationary state, so it is unnecessary to repeatedly calculate its azimuth angle.
S32, starting the micromechanical gyroscope by using the micromechanical gyroscope starting instruction, wherein the micromechanical gyroscope comprises an oscillator;
in one embodiment of the invention, the micromechanical gyroscope consists of a filter and a capacitor, wherein the oscillator is included in the filter, when the micromechanical gyroscope is started by the micromechanical gyroscope starting instruction, a circuit where the micromechanical gyroscope is located is switched on, the filter and the capacitor are activated to work, and then the oscillator in the filter generates oscillation to generate the vibration signal.
S33, generating the vibration signal by using the oscillator, and performing denoising processing on the vibration signal to obtain a denoised vibration signal;
s34, converting the vibration signal which is denoised into a voltage vibration signal;
and S35, calculating the azimuth according to a pre-constructed azimuth calculation formula and the voltage vibration signal.
In detail, the step of calculating the azimuth angle according to a pre-established azimuth angle calculation formula and the voltage vibration signal includes:
step A: establishing a direction coordinate system by taking a running surface where the moving object is located as a horizontal coordinate;
for example, the horizontal coordinate is the highway on which the high-speed running automobile is located, and the azimuth coordinate system can be constructed by taking the vertical plane perpendicular to the highway as the vertical coordinate.
And B: calibrating the position of the moving object at the speed immediately before the real-time speed is zero as an azimuth starting point;
for example, when the vehicle running at a high speed rolls over due to sudden stop of an obstacle ahead, the position of the vehicle at the speed immediately before the roll over can be calibrated as the azimuth starting point.
And C: calibrating the position of the moving object with the real-time speed being zero as an azimuth angle end point;
obviously, the rollover position of the vehicle running at high speed is taken as the azimuth end point.
Step D: connecting the azimuth starting point and the azimuth end point in the azimuth coordinate system to obtain a motion trajectory line of the moving object;
step E: and calculating a deflection angle of the motion trajectory line compared with the abscissa by using the azimuth angle calculation formula, and correcting the deflection angle by using the voltage vibration signal to obtain the azimuth angle of the moving object.
It should be explained that, the calculating the deflection angle of the movement trajectory line compared to the abscissa by using the azimuth calculation formula includes:
and calculating to obtain the deflection angle by adopting the following azimuth angle calculation formula:
wherein,
for the purpose of said deflection angle,
in the form of an inverse trigonometric function,
is the ordinate of the azimuth end point in the azimuth coordinate system,
is the ordinate of the azimuth starting point in the azimuth coordinate system,
is the abscissa of the azimuth end point in the azimuth coordinate system,
and the abscissa of the azimuth starting point in the azimuth coordinate system is used.
It should be understood that the voltage vibration signal is derived from the oscillator, when the moving object oscillates too violently, the generated voltage vibration signal is also extremely strong, so that if the voltage vibration signal is too high, it indicates that the moving object is in a stopped state, but an internal circuit signal of the moving object is abnormal, so that the deflection angle needs to be increased, and the azimuth angle of the moving object needs to be increased.
Further, after the azimuth is obtained, the azimuth is used to calculate the stopped state of the moving object, and in detail, the obtaining of the stopped state of the moving object by using the azimuth calculation includes:
respectively comparing the azimuth angle with a first preset threshold and a second preset threshold, wherein the first preset threshold is smaller than the second preset threshold;
when the azimuth angle is larger than the first preset threshold value but not larger than the second preset threshold value, judging that the stop state of the moving object is rollover;
when the azimuth angle is larger than the second preset threshold value, judging that the stop state of the moving object is reversed;
and when the azimuth angle is smaller than or equal to the first preset threshold value, judging that the stopping state of the moving object is normal stopping.
In a preferred embodiment of the present invention, the first predetermined threshold may be set at [80,120], and the second predetermined threshold may be set at [120,180 ].
And S4, detecting whether the moving object is impacted by the airbag detector.
According to the embodiment of the invention, the Hall sensor can be used for constructing and obtaining the safety airbag detector, the Hall sensor is arranged in the safety airbag, the safety airbag is opened and generates pressure when a moving object collides, and the Hall sensor is used for receiving the pressure to generate an impact signal.
And S5, when the moving object is detected to be impacted, sending the real-time speed and the stop state to a pre-constructed rescue center.
It should be explained that the rescue center includes a 120-center hospital, a 119-fire department, and the like, and when it is detected that the moving object is impacted, the real-time speed and the stop state are sent to a pre-constructed rescue center, where the stop state includes a positioning position obtained by a GPS positioning system in real time.
Compared with the background art: for the phenomenon that the triggering alarm condition is not fine enough, the alarm is automatically triggered only by sudden stop of driving or slight friction possibly occurring, and further the automatic alarm is excessively abused in the motion process, the embodiment of the invention firstly starts the motion tracking controller, wherein the motion tracking controller comprises a motion detector, a speed detector, a micro-mechanical gyroscope and an air bag detector, when a current signal generated by the motion detector is received, the current signal is used for activating the speed detector to detect the real-time speed of the moving object, when the real-time speed is zero, the azimuth angle of the moving object is calculated by using a vibration signal transmitted by the micro-mechanical gyroscope, the stop state of the moving object is calculated by using the azimuth angle, therefore, when the real-time speed is not zero, the stop state of the moving object is not blindly calculated, and further, whether the moving object is impacted is detected by using the air bag detector, and when the moving object is impacted, the real-time speed and the stop state are sent to a pre-constructed rescue center, so that the phenomenon that the automatic alarm is abused excessively is avoided by calculating the real-time speed and the stop state at first and using whether the moving object is impacted as a triggering condition communicated with the rescue center in the whole automatic alarm process. Therefore, the method, the device and the electronic equipment for capturing the parameters of the motion tracking controller in real time can solve the phenomenon that automatic alarm is excessively abused in the motion process.
