Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of low-altitude flight management, in particular to a method and device for processing electromagnetic signal data, electronic equipment and a non-transitory computer readable storage medium. BACKGROUND

[0002] With the gradual increase of low-altitude flight activities, the use of unmanned aerial vehicles and aircraft has been widely applied in various industries (such as logistics, agriculture, environmental monitoring, military, etc.). However, with the increasing complexity of low-altitude airspace, the electromagnetic interference and electromagnetic signal quality problems faced by aircraft have become more prominent. Electromagnetic signal interference can have a great impact on the communication, navigation and control systems of the aircraft, and may even cause flight safety hazards.

[0003] Therefore, how to monitor and predict the electromagnetic signal conditions in the flight airspace in real time, timely discover potential interference sources, and give early warnings is a crucial problem in low-altitude flight management. At present, many electromagnetic signal monitoring systems collect signal data through ground equipment and perform certain analysis. However, these systems have the following shortcomings: Lack of dynamic four-dimensional spatiotemporal description capability: traditional electromagnetic signal monitoring methods use two-dimensional or three-dimensional representation, which can only describe electromagnetic signals statically and cannot change with the change of flight trajectory, so it cannot accurately reflect the real-time changes of electromagnetic signals and the risk situation in the flight airspace.

[0004] Electromagnetic signal data representation method is not standardized: the current electromagnetic signal data format and transmission protocol standard is not unified, resulting in poor data compatibility between different devices and platforms, making it difficult to share data and cross-platform applications, affecting the real-time transmission and collaborative analysis of information.

[0005] Electromagnetic signal data reporting and processing method lacks real-time performance: the existing electromagnetic signal monitoring system often cannot quickly complete the real-time processing and reporting of signal quality and intensity after collecting single-point instantaneous electromagnetic signal data, so that the low-altitude flight management service system cannot timely discover the risk of abnormal electromagnetic environment in the vicinity after receiving the dynamic data of real-time aircraft.

[0006] Lack of comprehensive analysis and hierarchical evaluation of electromagnetic signal quality: the existing electromagnetic signal analysis lacks comprehensive and hierarchical evaluation of complex electromagnetic environment. SUMMARY

[0026] With reference to the appended drawings, below follows a detailed description of specific embodiments ceasing to the present application.

[0027] Figure 1 A flow chart of a method for processing electromagnetic signal data is shown in accordance with an example embodiment of the present application, as Figure 1The method shown includes steps S101 and S103. In the following, a method for processing electromagnetic signal data according to an example embodiment of the present application is described in detail. Figure 1

[0028] As shown in Figure 1 At step S101, a unified data model is constructed using the received electromagnetic signal data from the detection device, which contains spatial information, time information and / or multi-dimensional evaluation data of the electromagnetic signal data.

[0029] According to an embodiment of the present application, the electromagnetic signal data is reported after being collected in real time by a ground device based on an electromagnetic signal detection system.

[0030] In order to facilitate the description of the changes of electromagnetic signals in low altitude over time and space, according to an embodiment of the present application, before constructing a unified data model using the received electromagnetic signal data from the detection device, the method further includes: representing the electromagnetic signal data using a four-dimensional data space model including spatial dimensions and time dimensions, for describing the changes of the electromagnetic signal data in space and time, so that dynamic monitoring and early warning of the electromagnetic environment can be achieved.

[0031] In an embodiment of the present application, the spatial dimension data in the electromagnetic signal data is represented using a preset reference system and height reference; wherein the preset reference system and height reference include WGS84, CGCS2000 or PZ90 coordinate systems and MSL, HAE or AGL height systems. The preset reference system and height reference include WGS84, CGCS2000 or PZ90 coordinate systems and MSL, HAE or AGL height systems. WGS84 corresponds to the reference ellipsoid WGS84 ellipsoid, CGCS2000 corresponds to the reference ellipsoid CGCS2000 ellipsoid, and PZ90 corresponds to the reference ellipsoid PZ90 ellipsoid. HAE is ellipsoid height / height above sea level, and the height obtained directly based on GNSS is usually HAE, with the reference ellipsoid corresponding to the coordinate system identified by CRS as the reference. MSL is elevation or average elevation, and the reference surface (approximately replaced by geodetic datum) for calculating MSL is based on a geodetic datum model.

[0032] In some embodiments, when constructing a unified data model using the received electromagnetic signal data from the detection device, the collection time, collection location, signal strength, spectrum, quality, data transmission throughput, packet loss rate, reference signal reception quality and / or time delay are added to the electromagnetic signal data.

[0033] ​In specific embodiments, the frequency domain characteristics of the spectrum record signal are analyzed using fast Fourier transform, described in array format, and each array element object contains frequency, field strength and / or reference signal received power. Among them, frequency (frequency) represents the frequency of the electromagnetic signal, in Hz, number (number). feildStrength (field strength) represents the strength of the electromagnetic signal, in μV / m, number (number). RSRP (reference signal received power) represents the power of the electromagnetic signal, number (number), in dBm. In the 4G network, the value range of RSRP is -44 to -140 dBm, and the corresponding specification value is 0 to 97, and the actual value is equal to the specification value minus 140. In the 5G network, the value range of RSRP is -31 to 153 dBm, and the corresponding specification value is 0 to 127, and the actual value is equal to the specification value minus 156. The larger the reference signal received quality value, the better the signal quality, accurate to one decimal place; the value range is [-19.5, -3]; unit: dB. The signal-to-interference noise ratio is a signal quality indicator at the observation time, reflecting the ratio of signal to (interference + noise), and the larger the value, the better the signal quality. The signal-to-noise ratio is a signal quality indicator at the observation time, reflecting the ratio of signal to noise, and the larger the value, the better the signal quality. Data transmission throughput is the amount of electromagnetic signal data successfully transmitted through the communication system within a certain time.

[0034] In the present embodiment, by describing the electromagnetic signal data using a unified reference system and height reference, the electromagnetic signal data uploaded from the detection equipment in different coordinate reference systems is uniformly represented, forming a unified four-dimensional data, thereby facilitating real-time calculation and issuance of electromagnetic signal data, ensuring seamless docking and sharing of electromagnetic signal data between electromagnetic signal detection equipment and aircraft management platform, ensuring data compatibility and interoperability between different systems, and avoiding the information island problem caused by non-uniform data format in existing systems.

[0035] In other embodiments, when uniformly representing the electromagnetic signal data uploaded from the detection equipment in different coordinate reference systems, it is also necessary to remove duplicate data.

[0036] According to embodiments of this application, when constructing a unified data model using the received electromagnetic signal data from the detection device, it is also necessary to add a signal quality score, a data transmission quality score, and / or a comprehensive signal and transmission quality score to the multidimensional evaluation data. Specifically, the signal quality score SQS = (RSQR + 140) / 96, the data transmission quality score DTQS = 0.5 * (measured bandwidth / historical maximum bandwidth) + 0.5 * (1 - lossRate), and the comprehensive signal and transmission quality score DTSQS = 0.5 * SQS + 0.5 * DTQS, where RSQR is the reference signal reception quality and lossRate is the packet loss rate.

[0037] In this embodiment, a unified signal evaluation method is used to transform real-time static data in electromagnetic signals into evaluation data such as signal quality scores, data transmission quality scores, and / or comprehensive signal and transmission quality scores. This allows for a more intuitive identification of weak signal areas or strong interference areas in electromagnetic signals, and timely identification of potential interference sources and signal problems.

[0038] In some embodiments, signal quality / transmission quality is graded based on the Data Transmission Quality Score (DTQS) value, and the specific DTQS value corresponding to the grading standard is as follows: Excellent signal quality: (0.75, 1], good signal quality: (0.5, 0.75], moderate signal quality: (0.25, 0.5], weak signal quality: [0, 0.25].

[0039] The electromagnetic signal data is collected by the aircraft or the sensing device as a mobile carrier for observation sensors. According to other embodiments of this application, the data model further includes aircraft information and / or sensing device information. When constructing a unified data model using the received electromagnetic signal data from the detection device, product information and / or operational information of the aircraft are added to the aircraft information, and / or product information, operational information, location information, attitude information, and / or sensing device type information of the sensing device are added to the sensing device information.

[0040] In step S103, an electromagnetic signal data message is generated based on the data model.

[0041] In order to forward electromagnetic signal data represented by a unified standard to data receivers based on different reference coordinate systems and ensure seamless connection between different receivers, according to an embodiment of this application, in step S103, the electromagnetic signal data message is generated using the data model according to the habitual reference system of the receiver corresponding to the message of the aircraft, thereby realizing the conversion between different references and ensuring the compatibility and availability of information.

[0042] according toFigure 1 The embodiment shown solves the problem that the electromagnetic signal condition in the flight airspace cannot be detected in real time due to the non-uniform standards of the electromagnetic signal data delivery mechanism in the prior art by constructing the electromagnetic signal data into a unified data model and generating an electromagnetic signal data message based on the data model.
