Detailed Description
The present invention will be described in further detail with reference to the following examples and the accompanying drawings.
Example 1:
the invention provides a general radar state data acquisition device and method.
The radar health data includes digital signal monitoring data and radio frequency signal monitoring data.
As shown in fig. 1, the general state data collecting device of this embodiment implements adaptation to different types of radar health monitoring data interfaces, performs normalization processing after collecting radar health monitoring data, and implements output of a standardized network interface message to a PHM (fault prediction and health management) management platform. The general state data acquisition equipment comprises a radio frequency signal monitoring module, an enhanced preprocessing module and a processor. The enhancement preprocessing module is used for carrying out operation and preprocessing on the received digital signal monitoring data to realize compression, refinement and standardization of the digital signal monitoring data. The radio frequency signal monitoring module converts received radio frequency signal monitoring data into digital signals, calculates performance indexes such as frequency and power after the digital signals are subjected to digital processing, and records and stores the converted digital signals and the performance index data obtained by calculation. The enhanced preprocessing module and the radio frequency signal monitoring module are designed core hardware modules and are connected with the processor through a network. The processor is used as a main controller to realize the unified monitoring and scheduling of the enhanced preprocessing module and the radio frequency signal monitoring module; the PHM management platform may also be run on a processor.
1. Enhanced pre-processing module
As shown in fig. 2, the enhanced preprocessing module includes a power module, a motherboard, an interface module, and a computer module. The power module supplies power for other modules, the interface module realizes the acquisition and the reception of digital signal monitoring data in the radar health monitoring data, the motherboard provides support for data interaction between the interface module and the computer module, and the computer module mainly completes the preprocessing of the radar health data received by the interface module, and realizes the compression, the extraction and the standardization of the radar health monitoring data. The method for preprocessing the radar health monitoring data comprises the following steps:
(1) and the physical layer protocol is removed, and the standardization of radar health monitoring data is realized. For example, the optical fiber data has a physical layer protocol package, and the enhanced preprocessing module extracts effective data therein and uniformly converts the effective data into network protocol data.
(2) And (5) data compression. The digital signal monitoring data has a lot of redundant data information, for example, a set of valid information (including amplitude phase data and amplitude phase stability information) can be extracted from a plurality of sets of I, Q acquired data. For example, if there are 96 channels of digital signal monitoring data, each channel 32 has I, Q groups of data, each group I, Q of data is 2 bytes (Byte), the amount of digital signal monitoring data is 96 × 32 × 2 — 12 MB; and refining the 32 groups of monitoring data of each channel into a group of 4 types of data, wherein each type of data is 4 bytes, and the amount of the compressed monitoring data is 96 × 4 ═ 1.5 MB. Therefore, effective information is accurately extracted from the digital signal monitoring data, and the compression of the digital signal monitoring data can be realized.
Further, false alarm filtering is carried out aiming at the situation that false alarms occasionally appear in the digital signal monitoring data. For example, the enhanced preprocessing module may filter false alarms by using a fusion judgment technology, and output the same radar echo data to 10 radar signal processing modules at the same time, where one of the radar signal processing modules (e.g., the first module) reports abnormal data to the enhanced preprocessing module, and the other radar signal processing modules report normal data, and the abnormal data reported by the first module is considered as a false alarm, so that the abnormal data reported by the first module can be filtered.
After the processing, the enhanced preprocessing module reports the processing result to the PHM management platform.
2. Radio frequency signal monitoring module
As shown in fig. 3, the radio frequency signal monitoring module includes a radio frequency unit, a digital circuit unit, and a recording unit, and processes the radio frequency signal monitoring data in the radar health monitoring data. Specifically, the radio frequency unit monitors a frequency source, collects a radio frequency signal of the frequency source and converts the radio frequency signal into a digital signal; after the digital circuit unit processes the digital signal converted from the radio frequency signal, calculating to obtain performance indexes such as frequency, power and the like; the recording unit records and stores original data (digital signals before being processed by the digital circuit unit) and data after being processed by the digital circuit unit. As shown in fig. 4, the rf signal monitoring module uses superheterodyne technology, and three times of frequency mixing is performed on the signal generated by the local oscillator. The method specifically comprises the following steps:
1) respectively mixing the input radio frequency signals with a first local oscillation signal (local oscillation 1) to obtain a first intermediate frequency signal (intermediate frequency 1); the first intermediate frequency signal is amplified and filtered (to filter the first local oscillator signal and its harmonics), and then sent to the second mixer. The input radio frequency signals with different frequencies are mixed with corresponding first local oscillation signals with different frequencies, so that the frequency of the obtained first intermediate frequency signal is stabilized in a certain range, and the working frequency range of an amplifier and a filter is met.
2) And the first intermediate frequency signal (intermediate frequency 1) and the second local oscillator signal (local oscillator 2) which are sent into the second mixer are mixed by the second mixer to obtain a second intermediate frequency signal (intermediate frequency 2), and the second intermediate frequency signal and the second local oscillator signal are output after passing through a band-pass filter and an amplifier.
3) The output signal is then mixed with a third local oscillator signal (local oscillator 3) to obtain a third intermediate frequency signal (intermediate frequency 3).
After the above-mentioned multiple mixing, the input radio frequency signal is down-converted to intermediate frequency, so that the influence of the circuit on the noise coefficient of the whole receiver can be reduced, and the signal is amplified to a proper mixer input level. It can be understood that the input radio frequency signal may be down-converted to the intermediate frequency after being mixed only once; two or more mixing may also be used to down-convert the incoming radio frequency signal to an intermediate frequency, thereby reducing the effect of the circuit on the overall receiver noise figure while amplifying the signal to the appropriate mixer input level.
4) The signal down-converted to an intermediate frequency after mixing is sampled by an ADC. According to the software radio theory, the sampled digital signals are down-converted to a baseband to obtain signals of I and Q paths. And the DSP performs frequency test, phase noise analysis and spurious calculation on the two paths of signals, and finally reports a processing result to the PHM management platform.
3. Processor with a memory having a plurality of memory cells

The original data of the enhancement preprocessing module refers to digital signal monitoring data before compression, and the original data of the radio frequency signal monitoring module refers to radio frequency signal monitoring data after ADC sampling.
The main controller has a calibration function, and can finish the calibration of the enhanced preprocessing module and the radio frequency signal monitoring module through a preset calibration program, wherein the calibration comprises amplitude calibration, frequency calibration, time delay calibration, scanning time calibration, flatness correction, band-pass filter calibration and the like. The process of amplitude calibration of the main controller on the radio frequency signal monitoring module is shown in fig. 5, and the amplitude calibration is performed according to different frequency points. Setting signal source output power, dividing signal source output signals into two paths, and respectively sending the two paths of signals to radar state data general acquisition equipment and a power meter; setting the center frequency, the sweep width and the front end of the two paths of signals; respectively reading signal amplitude measured values of the radar state data general acquisition equipment and the power meter, solving and storing a difference value between the radar state data general acquisition equipment and the power meter, and setting an attenuation amount according to the difference value for calibrating the signal amplitude of the radar state data general acquisition equipment; if amplitude calibration is completed, namely the difference value between the signal amplitude of the radar state data general acquisition equipment and the signal amplitude of the power meter is 0, amplitude calibration is carried out on the signal of the next frequency point, if amplitude calibration is not completed, attenuation is changed, for example, the attenuation is halved compared with the attenuation used in previous calibration, the signal amplitude of the radar state data general acquisition equipment is calibrated again by using the changed attenuation, and the process is repeated until amplitude calibration is completed, and then amplitude calibration is carried out on the signal of the next frequency point until amplitude calibration of all frequency points is completed.
In addition, the main controller receives real-time BIT (built-in-test) information of the enhanced preprocessing module and the radio frequency signal monitoring module, and when some module is abnormal, the main controller reports the information to the PHM management platform in time to remind the PHM management platform of carrying out corresponding processing.
