Embodiment
The present invention will be further described in detail below in conjunction with the accompanying drawings.
The method of the invention is the reality by detecting luggage case in real time in space coordinates on tri- directions of X, Y, Z
Acceleration, and so as to judge the motion state of luggage case compared with given threshold, report can be sent when luggage case is stolen
Alert information, reminds luggage case owner.In order that judged result is relatively reliable, invention also contemplates that measurement luggage case and surrounding
Whether the distance of object of reference, comprehensive descision luggage case are moved.
Acceleration can be obtained by acceleration transducer measurement, but because the transportation environment residing for luggage case is easily led
Cause measurement result inaccurate, interference is larger, therefore actual acceleration of the present invention is by measuring luggage case in three coordinates
On acceleration and angular velocity of rotation integrate what is obtained, its measurement accuracy is relatively reliable.
The system for realizing the method for the invention is not unique, shown below is two specific embodiments and comes to this hair
It is bright to illustrate.
Embodiment 1
Motion detecting unit includes acceleration transducer and angular velocity of rotation sensor (gyroscope) in Fig. 1, is
System also includes ultrasonic sensor.The sensor is all connected with processing unit, and processing unit is connected with buzzer, works as processing unit
Judge to control buzzer warning when luggage case is moved.
Embodiment 2
Motion detecting unit includes acceleration transducer and angular velocity of rotation sensor (gyroscope) in Fig. 2, is
System also includes ultrasonic sensor.The sensor is all connected with processing unit, processing unit connecting communication unit and buzzer；
Communication unit is wirelessly communicated with mobile phone, and warning message can be sent to mobile phone, and mobile phone can also be single to communication
Member sends control instruction, such as controls buzzer to stop during buzzer malfunction；When processing unit judges that luggage case is moved time control
Buzzer warning processed, buzzer can be by mobile phone control stop alarm, or shutdown switch is set on luggage case.
System of the present invention is not limited to structure shown in Fig. 1 and Fig. 2, and sensor type or quantity can be carried out
Change, such as acceleration transducer and angular velocity of rotation sensor (gyroscope) are replaced using MPU6050；Processing unit it is equivalent
Replace, such as selection single-chip microcomputer or PLC；To the specifically chosen of wireless communication mode, such as bluetooth, 4G networks or to mobile phone
Send the modes such as short message.
The original number for the actual acceleration being illustrated in figure 3 when luggage case is static in embodiment 2 on three coordinate directions
According to due to hardware itself, the influence of environmental factor and acceleration of gravity, initial data is extremely unstable, static
When, initial data can constantly change, and be not used to follow-up processing.
It is to luggage case after the initial data of actual acceleration is handled through Kalman filtering algorithm when static as shown in Figure 4
Obtained datagram, data become stable in figure, and drift phenomenon is improved, and the motion state with reality is more closely, can
Reflect the acceleration change of luggage case.
As shown in figure 5, entering row stochastic motion by simulating luggage case, find during luggage case is overturn, due to
Chest and the angle in acceleration of gravity direction change and cause the acceleration in tri- directions of X, Y, Z to change simultaneously；In 100-
In 300 second period, push-and-pull is carried out to luggage case, now X, the acceleration value of Y direction are with chest and acceleration of gravity
The angle in direction and pull the change of chest dynamics and change, the acceleration kept stable of Z axis；At 320 seconds, chest
Carry out the movement of falling object, the acceleration of Y direction can keep stable state near acceleration of gravity, at X-axis acceleration
Near 0.By experiment, test it is a variety of in the case of data change, according to it is static when filtered data and mobile data look for
The acceleration threshold values gone out on three directions.
System by detecting the actual acceleration in three directions in real time, judge three direction actual accelerations whether be more than plus
Threshold speed, so as to judge the motion state of luggage case.Because caused shake can cause acceleration in train shutdown process
Instantaneous variation, now luggage case is in a safe condition that, in order to avoid train vibration influence disturbs to caused by system, system can be with
The distance of luggage case and surrounding objects is measured by ultrasonic sensor, the shifting of luggage case can be monitored in train shutdown process
Dynamic distance, alarm can be just sent when more than certain threshold value.Meanwhile system is handled acceleration information by algorithm,
And will it is new caused by data with first five time average value contrasted, filter out the moment caused by train movement acceleration change
Change, disturbed so as to eliminate train movement to caused by system.
Red curve represents the acceleration in X-axis in coordinate system in Fig. 3, Fig. 4 and Fig. 5；Blue curve is represented in Y-axis
Acceleration；Black curve represents the acceleration on Z axis.
Fig. 6 show data progress computing and obtains the process schematic of actual acceleration.To the acceleration measured and angle
Speed carries out Kalman filtering and handles to obtain angle；Angular velocity, angle are superimposed after carrying out pid control algorithm computing, are obtained everywhere
Data after reason are the actual acceleration of luggage case in the X, Y, Z direction, and kd, kp are the relevant parameters of PID control.
Fig. 7 is system flow chart, is comprised the following steps：
Measure luggage case it is static when actual acceleration in space coordinates on three directions, obtain three after filtering process
Acceleration rate threshold on individual direction；
Actual acceleration of the measurement luggage case in space coordinates on three directions in real time, and judge whether to be more than and accelerate
Spend threshold value；
Continue to measure if no more than if；If greater than then alert.
Be presented above embodiment of the present invention, by monitor luggage case acceleration of motion and due to
The change of the anglec of rotation caused by movement, and the data to obtaining carry out comprehensive analysis calculating, by obtained result and setting threshold
Value is compared, and effectively judges whether luggage case is moved.
But the present invention is not limited to described embodiment, such as measurement data is being handled to obtain actual acceleration
During degree, however it is not limited to the process described in embodiment, can be the order of the equivalent several steps of adjustment, equally can be with
The value needed, or change the concrete mode of alarm, such as buzzer is not provided with, warning message is sent out in a manner of short message
It is sent on mobile phone to remind luggage case owner, the technical scheme so formed is finely adjusted to be formed to above-described embodiment, this
Kind technical scheme is still fallen within protection scope of the present invention.
