Detailed Description
Embodiment 1, this embodiment is a device for judging that switch breach monitoring terminal support is not hard up, with the help of the acceleration sensor of switch breach monitoring terminal itself, and the acquisition circuit of gathering acceleration sensor input data, if acceleration sensing output is analog signal, still need have the AD converter, then just with the help of the throughput of switch breach monitoring terminal itself, handle the data of gathering, but the processing result is that switch breach monitoring terminal support is not hard up, reports to the police immediately. Of course, in this embodiment, the method further includes uploading the collected data to the background central upper computer, processing the data by the upper computer, and displaying the processing result in the background.
In the embodiment, in the method, an acceleration sensor on a turnout notch monitoring terminal is used for acquiring the accelerations S (t) (X (t), Y (t), Z (t)) of the device in each axis X/Y/Z at a certain time t in real time, and comparing the accelerations S (t), (Y) (t), Z (t)) with the accelerations S0 (X0, Y0, Z0) during initial installation of the device to calculate the included angle between two vectors; if the included angle is larger than a certain threshold value, the bracket of the turnout gap monitoring terminal is considered to be loosened, and in the test, S (t), X (t), Y (t), Z (t) and Z (t) are acceleration data in the X/Y/Z axis direction output by the acceleration sensor on the turnout gap monitoring terminal at the time t. The data acquisition and processing process is as follows:
step 1, judging whether the current state is a static state; the method comprises the following steps:
periodically acquiring acceleration data of each X/Y/Z axis within a period of time T, and calculating the average value and the standard deviation of the acceleration data of each X/Y/Z axis within the period of time T through the following formula; in the formula: n is the number of sampling points in time T, delta is the average value, and sigma is the standard deviation;

Whether the standard deviation sigma of the acceleration of each shaft is smaller than a given static threshold value or not, if yes, the equipment is judged to be in a static state, and the average value delta of the respective acceleration of the 3 shafts in the period of time is used as the static acceleration S of the current period of time; otherwise, waiting for the next interval time T and then calculating until the static state is judged;
step 2, calculating an included angle between the current static state and the initial static state;
Figure RE-RE-GDA0002648105330000047
step 3, judging whether the preset loosening threshold value is exceeded or not; in the step, if the looseness exceeds a set looseness threshold value, a support looseness alarm of the turnout gap monitoring terminal is sent out.
Step 4, calculating the acceleration S (t) of each axis X/Y/Z at a certain time t, (X (t), Y (t), Z (t)), and the included angle between the acceleration S0 at the initial installation of the equipment and the acceleration S0, Y0, Z0 according to the following formula:
Figure RE-RE-GDA0002648105330000051
the change of the installation position of the equipment cannot be reflected by (t) at a certain moment, and the vibration is stronger and larger but is not loosened according to the instantaneous acceleration.
Specifically, in this embodiment, the acceleration sensors on the gap monitoring terminal are used to acquire the accelerations S (t), (X), (t), Y (t), and Z (t) of the device in the X/Y/Z axes at a certain time t in real time, and the accelerations S (t), (X), (t), Y (t), and Z (t)) are compared with the accelerations S0 (X0, Y0, and Z0) at the time of initial installation of the device, so as to calculate the included angle between the two vectors. And if the included angle is larger than a certain threshold value, the terminal is considered to be loosened.
The invention comprises two algorithms, namely the judgment of the static state and the calculation of the change of the installation position. The equipment looseness is detected by detecting the static state and the position change of the equipment in real time.
Firstly, judging a static state:
the notch monitoring terminal periodically collects acceleration data of X/Y/Z axes in a period of time T, and judges whether the equipment is in a static state or not by calculating whether the standard deviation of the acceleration of each axis in the period of time is smaller than a given static threshold value or not. The calculation formula of the average value and the standard deviation of the acceleration of each axis in the period T is as follows, wherein N is the number of sampling points, delta is the average value, and sigma is the standard deviation.
An X axis:

Figure RE-RE-GDA0002648105330000053
y-axis:

z-axis:
Figure RE-RE-GDA0002648105330000061
Figure RE-RE-GDA0002648105330000062
if the device is in a static state, taking the average value delta of the respective accelerations of the 3 axes in the period of time as the static acceleration S of the current period of time, namely the current static position of the device. And if the static condition is not met, waiting for the next interval time T to be calculated again.
Initial installation position determination:
after the notch monitoring terminal is installed and fixed on the site, the current static acceleration S0 (x0, y0 and z0) can be obtained according to the method, namely the initial installation position of the equipment is used for subsequent looseness detection. If the installation position of the equipment is adjusted, the static acceleration corresponding to the initial installation position also needs to be updated correspondingly.
Calculating a change in installation location
As shown in fig. 1, a black square 1 represents an initial installation position of the gap monitoring terminal, and a black square 2 represents a current position after a period of operation. The arrow direction is the direction of the acceleration vector, and the included angle between the two directions is. By mathematical formulae
Figure RE-RE-GDA0002648105330000063
The size of the included angle can be calculated. The size of the included angle can reflect the change of the installation position of the equipment.
Determination of stent loosening
The gap monitoring terminal can continuously monitor the static state and calculate the included angle between the current static state and the initial static state. When the stent loosens, a threshold may be exceeded, which triggers a loosening alarm. When the gap monitoring terminal is disconnected due to looseness and the value cannot be obtained, the upper computer can trigger the offline alarm of the device by detecting that the device is disconnected.
When the communication is normal, the notch monitoring terminal can frequently calculate (t) and report the value to the upper computer, and when the communication is static, the value can be calculated, if the value is greater than a threshold value, the notch monitoring terminal is bound to be loosened, and a loosening alarm is reported to the upper computer.
When the vibration is strong, the support is loosened, the communication connecting line of the gap monitoring terminal is disconnected, the upper computer finds that the communication of the gap monitoring terminal is interrupted, and when the reported (t) before interruption is just greater than a threshold value, the connection is probably dropped due to the vibration, and the upper computer should actively trigger an alarm.
