In order to time align the data of the respective sensors, in some embodiments of the present invention, the preset number of single frame reference times includes a first single frame reference time; step S103 includes:
Determining second intermediate data of the preset number corresponding to the first sensors according to the first sensors with the fastest sending frequency in the preset number of the sensors;

In a specific embodiment of the present invention, after determining the first sensor with the fastest frequency, a first timestamp may be determined according to the second intermediate data of the first sensor, so that, according to the difference between the first timestamp and the first time alignment reference line, a preset number of single frame reference times and single frame reference lines are determined, fig. 3 is a schematic diagram of the multi-element two-dimensional data matrix buffer area provided by the present invention, as shown in fig. 3, for example, if the vibration measuring grating array 1 is the first sensor, the timestamp in the data packet of the vibration measuring grating array 1 is taken as the first timestamp, the first timestamp is respectively 1680849900ms, 1680849950ms, 1680850000ms, 1680850050ms, and the like, and corresponds to 0ms, 50ms, 100ms, and 150ms on the time axis, and when the first time alignment reference line is 0, the difference T is respectively 0, 50, 100, 150,0-50ms, 50-100ms, and 100-150ms are data packets, so that a single frame is 50, and after the data packet is stacked between 0-50ms, the data packet is popped from 50ms to 100ms, and the data packet is popped from the center until the server receives the data packet. The data packet of each sensor can be imported to the corresponding position in the multi-element two-dimensional data matrix buffer area according to the first timestamp and the type of the sensor, when the data packets of all the sensors below the single frame datum line are imported, the first intermediate data of the vibration measuring grating array 1, the vibration measuring grating array 2, the temperature measuring grating array and the pressure film T=0 are popped together, so that the data packets of all the sensors with T=0 are obtained, and time alignment is realized.

In some embodiments of the present invention, step S103 further includes:
if the first intermediate data of the second sensor at the position below the single frame datum line is not imported in the matrix buffer zone, judging whether the third intermediate data of the second sensor at the position below the single frame datum line is imported in a preset time;

if not, processing the first intermediate data imported by each sensor below the single frame reference line to obtain the third single frame data packet of each sensor corresponding to the first single frame reference time.
It should be noted that: if the first intermediate data of the sensor which is below the single frame datum line and is in the preset number is not imported, the sensor which is not imported is determined to be the second sensor, the data packet of the second sensor is the third intermediate data, the fact that the third intermediate data of the position below the single frame datum line of the second sensor is not imported in the preset time is judged, if the first intermediate data and the third intermediate data of the sensors below the single frame datum line are imported, the first intermediate data and the third intermediate data of the sensors below the single frame datum line are stacked together, and if the first intermediate data and the third intermediate data of the sensors are not imported, the first intermediate data of the imported sensors are stacked together.
In a specific embodiment of the present invention, as shown in fig. 3, after the data packets of t=0 are popped, it is required to poppe the data packets of t=50, at this time, the single frame reference line should be at a position of 100ms, and the data packets of t=50 of the vibration sensing grating array 2 are missing, the data packets of t=50 of the pressure film are missing, the data packets of the vibration sensing grating array 2, the temperature sensing grating array and the pressure film can be determined as the second sensor, the missing data packets are determined as the third intermediate data, then it is possible to determine whether the third intermediate data is imported to the data packets of t=50 in a preset time, if all the data packets are imported, then the first intermediate data of t=50 of the vibration sensing grating array 1, the third intermediate data of t=50 of the temperature sensing grating array 2 t=50, the third intermediate data of the pressure film t=50, and the third intermediate data of the pressure film t=50 are popped together, and the data packets of each sensor of t=50 are obtained, if the preset time is at least one of the third intermediate data of t=50 is exceeded, and the third intermediate data of the first intermediate data of t=50 is not being imported, and the third intermediate data of t=50 is not being sensed, and the third intermediate data of t=50 is not being imported, and the third intermediate data of the intermediate data 1 t=50 is directly sensed, and the third intermediate data of the intermediate data is not being imported to be imported to the intermediate data of the intermediate data 1 is directly, and 50 data is required to be imported, other cases are similar processes.
In some embodiments of the present invention, step S103 further includes:
If the first intermediate data of the second sensor at the position below the single frame datum line is not imported in the matrix buffer zone, copying the first intermediate data closest to the single frame datum line in the second sensor to obtain fourth intermediate data of the second sensor at the position below the single frame datum line;
