Description

Technical Field

[0001] The present invention relates to the technical field of optical measurement equipment, and in particular to an automatic operation test method and system for optical measurement equipment based on ADS-B. Background Art

[0002] Optical measurement equipment is an important component of range measurement, providing exterior ballistic measurement and real-time scene data for test missions. Currently, the degree of automation of optical measurement equipment for tracking flying targets is low, and manual operation and decision-making account for a large proportion. The success of the mission is limited by the proficiency of the operator. When the target is flying at a fast speed, the scene is complex, and continuous instructions need to be issued, the ability of personnel in various positions to cooperate and coordinate is tested. If the system can autonomously perform process control and tracking control, it will greatly reduce the pressure and difficulty of operation on the operator, and maximize the tracking performance of the equipment to ensure the collection of key information of the test mission.

[0003] As optical measurement equipment becomes more and more mature, the data interaction capabilities of each subsystem within the equipment have been improved. With the rapid development of artificial intelligence technologies such as deep learning, optical measurement equipment has added more means for image-based data processing and task understanding. Driven by both demand and technological progress, the automation upgrade of optical measurement equipment is imminent. However, since automatic operation is a systematic project, not only does it require intelligent upgrades of each subsystem, but the system also needs to be continuously tested for mission scenarios. The accumulation of a large amount of data is a necessary condition for improving the ability of automated operation. However, the measurement tasks at the shooting range have the actual situation of limited tasks and cannot be tested in actual combat. Therefore, the design of a set of optical measurement equipment automated operation test methods and systems has become an important factor in ensuring the effectiveness of automated research and development.

[0004] The current solutions for the automated operation of optical measurement equipment are mainly aimed at satellite monitoring tasks, while the automated operation solutions for target range optical measurement tasks for rocket and missile launch and landing point observation scenarios are still in the early stages of development. A few solutions only provide automated operation processes for a single scenario, but do not provide test methods and system construction for how to automatically operate the system. Simply using target range mission data for testing has the problems of a single tracking process, inability to verify the ability to handle abnormal situations, and inability to maximize the efficiency of automated operation. If simulation data is used, there will be a large deviation between the simulated scenario and the actual scenario, and too much process testing will be performed without paying attention to performance improvement. The automation of other optical measurement equipment mission scenarios, such as automated system calibration and automated space target testing, although no system testing methods and scenarios have been proposed, because their observation targets are satellites and stars, they have the characteristics of easy acquisition of test scenarios and inconsistency with mission scenarios.

[0005] Specifically, Chinese patent document CN117148873A discloses a one-button automatic tracking system and method for optical measurement equipment, which is an attempt to automate the operation of the optical measurement equipment in the shooting range. However, the technical solution only describes the automation implementation scheme, and does not describe how to perform function and performance testing during the system design process. The method does not reflect the performance improvement effect of the solution through the test system. Chinese patent document CN115390575A discloses a method and device for realizing automatic tracking of unmanned aerial vehicles based on ADS-B, which uses ADS-B to obtain target information and assists unmanned aerial vehicles in completing long-distance tracking of targets. However, this method is not aimed at optical measurement equipment, and the use of ADS-B data is only as the data source for the unmanned aerial vehicle to follow, and the target and ADS-B are not fully used to test the performance of the system. Other methods for automated operation of optical measurement equipment include Chinese patent document CN113566848A which discloses an automatic star calibration method and system for optical measurement equipment based on the Loongson platform, and Chinese patent document CN110926501A which discloses an automatic calibration method, system and terminal device for optical measurement equipment. All of them are automation in system calibration, and the test verification work can be completed by relying on stars, and are not aimed at target range mission scenarios. Summary of the invention

[0078] The inventive concept of the present invention is:

[0079] In response to the needs of system automation test methods and system construction, the ADS-B-based optical measurement equipment automation test method and system of the present invention restores the mission scenario and data flow during the mission process to the greatest extent, ensures the consistency of data processing in the test scenario and the subsystems of the mission scenario, and has relatively low requirements for the test location, which only needs to be deployed in the urban area where the take-off and landing of airport aircraft can be observed.

[0080] The present invention is described in detail below with reference to the accompanying drawings.

[0081] The present invention provides an automated testing method and system for ADS-B-based optical measurement equipment based on ADS-B data as a guide and with civil aircraft as real-time observation targets. The testing system provides a testing environment with a real scene. The system consists of the following components: Figure 1As shown, it includes: antenna, ADS-B receiver, integrated test control computer, time system, storage device and network switch. The functions of each part are as follows:

[0082] Antenna: Responsible for receiving ADS-B messages sent by surrounding target aircraft and transmitting the received electromagnetic wave signals to the ADS-B receiving device. The antenna operates in the 1090MHz frequency band and uses radio frequency receiving technology to capture ADS-B data broadcast by nearby target aircraft to obtain the flight status information of the target aircraft.

[0083] ADS-B receiving device: Receives ADS-B messages periodically sent by target aircraft in real time through antenna. The device is composed of tuners, filters, analog-to-digital converters and other components, and also integrates programmable logic devices and microcontrollers. The message information in the ADS-B message contains flight status information, which includes the location information, altitude, speed, heading and unique identification number of the aircraft. And send the message information to the integrated test control computer.

[0084] Comprehensive test control computer: This computer is responsible for processing all data within the test system, including receiving the message information sent by the ADS-B receiving device and parsing the target position information, receiving the image and data information of the optical measurement equipment, receiving the time information of the time system and triggering the synchronization signal. It is also responsible for process control to ensure the smooth progress of the test and provide an evaluation interface for the automated operation test items.

[0085] Timing: Provides trigger synchronization signals and time information for the test system.

[0086] Storage device: completes real-time storage of target position information and optical measurement equipment data, facilitating further testing of this type of tracking situation.

[0087] Network switch: The test system uses network transmission for data transmission, the protocol is UDP, and the switch is used for data interaction.

[0088] In the ADS-B based optical measurement equipment automated operation test system of the present invention, the system data flow is as follows Figure 2 As shown, the testing method applicable to the testing system of the present invention comprises the following steps:

[0089] Step 1: The ADS-B receiving device outputs the message information in the received ADS-B message to the integrated test control computer;

[0090] Step 2: The comprehensive test control computer receives the message information and parses the target position information; receives the image and data information of the optical measurement equipment; receives the time information of the time system and the trigger synchronization signal;

[0091] The integrated test control computer works under the drive of the trigger synchronization signal of the time system, receives the time information of the time system as the time reference, and receives the image and data information of the optical measurement equipment (photoelectric theodolite) to realize the centralized processing of the test data.

[0092] Step 3: The integrated test control computer sends the civil aviation position of the target aircraft to be tracked to the optical measurement equipment;

[0093] The decoded ADS-B information can display the location information of the civil aviation, and the integrated test control computer can send the location of the civil aviation to be tracked to the optical measurement equipment (photoelectric theodolite).

[0094] Step 4: The image and data information of the optical measurement equipment and the target position information parsed by the ADS-B receiving device are stored in a storage device for secondary test verification.

[0095] According to the test needs, all the data in the process can be saved for secondary test verification. All the data here include: images and data information of optical measurement equipment (photoelectric theodolite), and target position information analyzed by ADS-B receiving device.

[0096] The data flow of the ADS-B-based optical measurement equipment automatic operation test system of the present invention is compared with the external data flow of the actual shooting range optical measurement equipment. Figure 3 As shown. Analyzing from the external data interface of the optical measurement equipment, the data type and flow direction provided by the optical measurement equipment automatic operation test system based on ADS-B of the present invention are completely consistent with the actual working process of the optical measurement equipment in the shooting range, thereby ensuring the integrity of the test environment of the optical measurement equipment automatic operation test system based on ADS-B of the present invention, further reflecting the technical advantages.

[0097] The workflow of the ADS-B-based optical measurement equipment automated operation test system of the present invention is as follows: Figure 4 As shown, the following steps are included:

[0098] When preparing to perform automated operation tests, ensure that the optical test equipment has been debugged and can perform automated operation tests.

[0099] Turn on the test system, start the ADS-B receiving device, receive the ADS-B messages sent by surrounding target aircraft through the antenna, and transmit the received electromagnetic wave signals to the ADS-B receiving device. After demodulating the signal, the message information is sent to the integrated test control computer in the form of UDP network.

[0100] The integrated test control software runs in the integrated test control computer, and the integrated test control software receives the time system time as the time reference and trigger synchronization signal. The target message parsing and selection module of the integrated test control software first decodes a large amount of target message information in the airspace according to the prescribed protocol, and completely parses the position information, altitude, speed, heading, unique identification number and current data packet time information of each aircraft, and displays the above-mentioned flight status information in a tabular form. Due to the layout of the optical measurement equipment, low-elevation angle targets will be blocked by the surrounding environment, so the message parsing and selection module will classify each aircraft, and the observable targets are marked in green and displayed in front of the table, and the unobservable targets are marked in red and displayed behind the table. According to the tester's operation, one of the flying targets is selected as the test target, and the position information of the test target is sent to the optical measurement equipment.

[0101] The optical measurement device currently enters the automatic operation mode. After receiving the target position information, it will automatically process the position information and control the optical measurement device to search and capture the target. The test system determines whether the target is successfully captured and enters the automatic operation process based on the image and data information uploaded by the optical measurement device. If the target is not found, the flight target (i.e. the target to be observed) is reselected and the guidance data is forwarded to the optical measurement device. If the target is found, the real-time image system data information of the optical measurement device is received, and the image and data information uploaded by the optical measurement device are analyzed and processed. The following describes the analysis and processing process.

[0102] The ADS-B-based optical measurement equipment automated operation test system of the present invention reserves a variety of automated operation index test interfaces, including:

[0103] Based on the image information, the automatic dimming, focusing and zooming status are displayed and evaluated through the interface;

[0104] Based on the data information, an evaluation interface is provided for external guidance data processing and target tracking stability;

[0105] An interface for evaluating the correctness of target extraction position based on image and data information;

[0106] According to the data information, the automated process is tested to check the correctness of steps such as data storage, data generation, data analysis and organization, and data upload, and to conduct an evaluation interface.

[0107] After the test is completed, check whether the data is recorded. If yes, the target position information and the image and data information of the optical measurement equipment are recorded and the test is ended. If not, the test is ended directly.

[0108] As a testing platform, the comprehensive test control software adopts a modular design. Each module runs independently in a private thread. Various types of data information complete standardized interface design, and the evaluation algorithm supports dynamic upgrades.

[0109] When the automated test is completed, the data from the test process can be stored in a standardized manner according to the needs of the developer of the optical measurement equipment to be tested, which is convenient for subsequent secondary testing of the algorithms in each system.

[0110] The following is a detailed description of various automated operation index test interfaces in the automated operation test system for optical measurement equipment based on ADS-B of the present invention.

[0111] The various automated operation index test interfaces reserved in the automated operation test system of optical measurement equipment based on ADS-B of the present invention define standard input and output for the subsequent modular design of corresponding evaluation methods, including: data elements, types and data formats.

[0112] The data formats of the above four types of evaluation interfaces are defined below:

[0113] 1. Based on the image information, the automatic dimming, focusing and zooming status are displayed and evaluated through the interface.

[0114] Input information of this interface: image data of multiple detectors, the data frequency is consistent with the camera working frame rate;

[0115] The output information of this interface: the scores of various lens control effects measured in percentage, including dimming effect, focus effect, and zoom effect.

[0116] 2. Based on the data information, an evaluation interface is provided to guide data processing and target tracking stability.

[0117] Input information of this interface: measurement data and status information of each subsystem, data frequency 100Hz;

[0118] Output information of this interface: target tracking stability effect measured in percentage.

[0119] 3. Based on the image and data information, an interface is used to evaluate the correctness of the target extraction position.

[0120] The input information of this interface: image data of multi-channel detectors, the data frequency is consistent with the camera working frame frequency; measurement data information and status information of each subsystem, the data frequency is 100Hz;

[0121] Output information of this interface: the correctness of target extraction position measured in percentage.

[0122] 4. Test the automation process based on the data information, check the correctness of steps such as data storage, data generation, data analysis and organization, and data upload, and conduct an evaluation interface.

[0123] Input information of this interface: measurement data and status information of each subsystem, data frequency 100Hz;

[0124] The output information of this interface: the correctness of the automated operation process control measured in percentage.

[0125] After decomposition, the standard interface types of the four types of evaluation interface inputs in the ADS-B-based optical measurement equipment automated operation test system of the present invention include: image and data. The output interfaces are all 100-point scoring, and the 100-point scoring result is a single type of output, without the need for detailed design.

[0126] In the ADS-B-based optical measurement equipment automated operation test system of the present invention, two types of input interfaces, image and data, are defined in detail.

[0127] 1. Image input interface definition:

[0128] In order to ensure that the image format can adapt to various resolutions and bit depths at the software level and has universal applicability, the data structure of the image input to the module is designed. The structure defined by the data structure is as follows:

[0129] struct Image {

[0130] int width; / / Image width

[0131] int height; / / Image height

[0132] int bitDepth; / / Pixel bit depth, 8, 16, 24, etc.

[0133] PixelFormat format; / / Pixel format, such as RGB, grayscale, etc.

[0134] uint8_t* data; / / Image data pointer

[0135] };

[0136] Resolution-adaptive design: Use the width and height fields to define the image resolution;

[0137] Bit depth adaptability design: Use a field (bitDepth) to indicate the bit depth of each pixel, commonly 8-bit, 16-bit, 24-bit, etc. Each pixel of the image can have a different bit depth, and even supports different modes such as grayscale and RGB images;

[0138] Color format adaptability design: Use pixel format (PixelFormat) to represent the color type of the image. Common ones include grayscale (one value per pixel, usually single-channel data), RGB (each pixel contains 3 channels (red, green, blue), the depth of each channel is determined by bitDepth), RGBA (each pixel contains 4 channels (red, green, blue, transparency), the depth of each channel is determined by bitDepth;

[0139] Image data content: Image information is stored using the original data pointer (data), which points to the bits of image data in memory.

[0140] 2. Data input interface definition:

[0141] The data input interface needs to input information for each evaluation module, including time information, angle information, image processing result information, device status information, etc. The problems faced are the diversity of data types, the subsequent expansion of the number of data, and the problem of multi-platform adaptation.

[0142] The ADS-B-based optical measurement equipment automated operation test system of the present invention uses a JSON file structure to define data, unifies the data format, and enables the system to adapt to the transmission of various data types, dynamically supports the transmission of different data volumes, and can process both single data items and multiple data items.

[0143] The JSON file structure in the ADS-B-based optical measurement equipment automated operation test system of the present invention includes two parts: Header (metadata) and Data (data item). Among them:

[0144] Header (metadata): Contains metadata related to the data packet, such as timestamp, data source, and checksum. This information helps the receiver understand and verify the data.

[0145] Data (data item) design, each data item contains the following fields:

[0146] type: The type of data, such as int, double, bool, string, etc. This field enables the receiver to correctly parse the data.

[0147] name: A name or identifier for a data item that helps explain what the data means.

[0148] value: The actual value, which can be various types of data.

[0149] length: Optional field. Especially for variable-length data (such as strings, timestamps, complex data, etc.), the length of the data needs to be clearly recorded.

[0150] Example of data input interface definition:

[0151] {

[0152] "header": {

[0153] "timestamp": "2024-12-17T15:30:00Z",

[0154] "source_id": "sensor_01",

[0192] } ]

[0194] }

[0195] The flow and type diagram of input and output data of four types of evaluation modules in the comprehensive test control computer are as follows: Figure 5 shown.

[0196] Aiming at the current situation that there is no effective testing method in the process of developing and testing the automated operation of target range optical measurement tasks, the present invention provides an automated operation testing method and system for optical measurement equipment based on ADS-B, which solves the current problem that it is impossible to effectively test the automated operation capability of target range optical measurement equipment.

[0197] The ADS-B-based optical measurement equipment automated operation test method and system of the present invention provide data types and data flows for the optical measurement equipment, which are consistent with the actual scenarios of the working process of the optical measurement equipment in the actual shooting range.

[0198] The ADS-B-based optical measurement equipment automated operation test method and system of the present invention are modularly designed based on three main evaluation indicators: dimming, focusing and zooming, external guidance data processing and tracking stability, and target extraction stability. An evaluation method interface is reserved for each indicator, and each evaluation method supports modular expansion, thereby ensuring the scalability of the method and system.

[0199] The ADS-B-based optical measurement equipment automated operation test method and system of the present invention uses civil aircraft as test observation targets based on ADS-B, provides a test environment with real scenes, and avoids the influence of unreality and imperfection of simulation data on the actual use of the final system.

[0200] The invention discloses an automated operation test method and system for optical measurement equipment based on ADS-B. The system can generate external guidance data for aircraft targets to simulate actual mission scenarios. The system provides maneuverable targets and can test automatic dimming, focusing, and zooming functions. The system can test the automation of the entire process, including steps such as data storage, data generation, data analysis and organization, and data uploading. The system can store scene data to facilitate the system to conduct targeted training and debugging of multiple groups of data afterwards.

[0201] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
