Detailed Description
The aviation superconducting full tensor magnetic gradient data acquisition and control system not only needs to acquire full tensor magnetic data, but also needs position and attitude data corresponding to the full tensor magnetic data in real time, and the higher the synchronism is, the better the synchronism is. The attitude data is used for effectively eliminating interference introduced by the full-tensor magnetic data in the motion state, and then the spatial distribution information of the measured area can be obtained only by corresponding the full-tensor magnetic data after the interference is eliminated with the position information. Therefore, the measurement accuracy of the position and attitude data and the synchronism with the full tensor magnetic data determine the data quality of the aviation superconducting full tensor magnetic gradient data acquisition and control system, but the full tensor magnetic data and the position and attitude data are asynchronous due to different data sources of the full tensor magnetic data and the position and attitude data.
The data synchronization of the position, attitude data and full tensor magnetic data may be obtained by resampling the full tensor magnetic data, because the position and attitude data are directly acquired from the SPAN-CPT after the inertial navigation system SPAN-CPT is directly connected with the data acquisition and control system, thus, at this point the delay in position and attitude data is negligible, but before resampling the full tensor magnetic data, since the full-tensor magnetic data needs to be integrated and amplified by the readout circuit and analog-to-digital converted, at this time, the full tensor magnetic data can generate delay, so that the re-sampled full tensor magnetic data can generate certain delay compared with the position and posture data, therefore, there is a certain time delay between the resampled full tensor magnetic data and the position and orientation data.
Based on the above problems, the application provides a data synchronization test device based on an aeromagnetic superconducting full tensor magnetic gradient measurement and control system, which is used for testing the time delay generated in the process of sampling full tensor magnetic data, position data and attitude data by using the aeromagnetic superconducting full tensor magnetic gradient measurement and control system, and further adjusting the resampling parameter of the full tensor magnetic data through the time delay, so that the synchronization precision of the full tensor magnetic data and the position attitude data is improved.
It should be understood that the specific embodiments described herein are merely illustrative of the present application. And are not intended to limit the present application.

It should be noted that, in the embodiment of the present application, the preset frequency is 50 hz, and a specific preset frequency may be specified according to an actual situation, and the embodiment of the present application is not limited herein.
It should be noted that the sine wave signal generated by the signal generator may not necessarily have a zero phase, nor is it required to be triggered by the PPS signal.
It should be noted that the NI9215 module and the full tensor magnetic data simulation acquisition module are respectively used for simulating a process of acquiring position and attitude data in an actual situation and a process of acquiring resampled full tensor magnetic data.
In the embodiment of the application, a data synchronization testing device based on an aeromagnetic superconducting full tensor magnetic gradient measurement and control system is connected with an inertial navigation system SPAN-CPT through a data acquisition and control system; the data acquisition and control system is further configured to acquire a PPS signal from the SPAN-CPT when a preset time is reached; and transmitting the PPS signals to an NI9215 module and a full tensor magnetic data analog acquisition module.
Note that since the PPS signal is reliable after the SPAN-CPT convergence, it can be understood that the PPS signal is acquired from the SPAN-CPT after the SPAN-CPT convergence.
In this embodiment of the application, the NI9215 module is further configured to acquire a sine wave signal based on PPS signal triggering and by using a first sampling frequency, to obtain a first sine wave signal; and transmitting the first sine wave signal to a data acquisition and control system.
It should be noted that, because the data acquisition and control system is connected to the SPAN-CPT, in an actual situation, the data acquisition and control system can directly acquire pose data, that is, position and attitude data in the SPAN-CPT, and the delay can be ignored, so that the present application uses the NI9215 card to simulate the process of acquiring pose data in an actual situation, and because the NI9215 card is a non-delay Successive Approximation Register (SAR) type data acquisition card, the present application includes 4 synchronous sampling analog input channels, there is no sampling delay but microsecond-level conversion time, and the conversion time affects the sampling frequency and does not generate sampling delay, so that the present application can be used for simulating the process of acquiring pose data in an actual situation.
In the embodiment of the present application, the NI9215 acquires the sine wave signal by using the first sampling frequency of 1000 hz.
It should be noted that, in the embodiment of the present application, the sine wave signal is acquired by using the non-delay NI9215 card to simulate a process of acquiring the position and orientation data in the SPAN-CPT by the data acquisition and control system in an actual situation.
In the embodiment of the application, the full tensor magnetic data analog acquisition module comprises a reading circuit and a first data acquisition board card; the reading circuit is configured to perform integral amplification on the sine wave signal to obtain an integral amplified sine wave signal, and transmit the integral amplified sine wave signal to the first data acquisition board card; the first data acquisition board card is configured to acquire the sine wave signal subjected to integral amplification by using a second sampling frequency based on PPS signal triggering to obtain a second sine wave signal, and transmit the second sine wave signal to the data acquisition and control system.
It should be noted that, in an actual situation, resampling of the full-tensor magnetic data is realized through an upper computer program of the data acquisition and control system, so that, during simulation, a sine wave signal generated by the signal generator needs to pass through the reading circuit and the first data acquisition board card, and after obtaining a second sine wave signal, the second sine wave signal is sent to the data acquisition and control system, and the data acquisition and control system receives the second sine wave signal to perform resampling processing on the second sine wave signal, and performs phase comparison on the obtained second sine wave signal and the first sine wave.

It should be noted that, in the embodiment of the present application, the second sampling frequency is 1000 hz.
In practical situations, when the resampling rule is used to resample the full-tensor magnetic data, the full-tensor magnetic data is time-stamped based on the PPS signal in the SPAN-CPT, so that, during simulation, the acquisition of the full-tensor magnetic data needs to be triggered based on the PPS signal in the SPAN-CPT, and the data is resampled after the acquisition.

It should be noted that the determination process of the first operating parameter is a preparation operation before the test starts, and the reaching of the preset time may be understood as determining the first operating parameter of the readout circuit after the SPAN-CPT converges before the test starts, and transmitting the first operating parameter to the amplifying circuit, so that the readout circuit is in a normal operating state.
In an embodiment of the application, the data acquisition and control system is further configured to extract a first phase of the first sine wave signal and a second phase of the resampled second sine wave signal, and determine a difference between the first phase and the second phase as the phase difference to achieve phase synchronization between the first sine wave signal and the second sine wave signal based on the phase difference.
It should be noted that, after the data acquisition and control system obtains the first sine wave signal and the resampled second sine wave signal, the first phase of the first sine wave signal is extracted, the second phase of the second sine wave signal is extracted, the phase difference between the first sine wave signal and the second sine wave signal is determined based on the first phase and the second phase, and then the resampled second sine wave signal is compensated by the phase difference to realize the phase synchronization between the first sine wave signal and the resampled second sine wave signal.
