Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of optical measurement equipment, and particularly relates to an optical measurement equipment automatic operation test method and system based on ADS-B. BACKGROUND

[0002] The optical measurement equipment is an important component of the target range measurement, and provides the external trajectory measurement and live scene data for the test task. The current optical measurement equipment has low automatic degree in tracking the flying target, and the proportion of manual operation and decision is large. Whether the task succeeds or not is limited by the proficiency of the operator. When the target flies fast, the scene is complex, and the continuous instruction issuing is required, the ability of the coordinated cooperation of the personnel in each post is greatly tested. If the system can independently control the process and track, the pressure and operation difficulty of the operator can be greatly reduced, the tracking performance of the equipment is maximally exerted, and the acquisition of the key information of the test task is ensured.

[0003] With the increasing maturity of the optical measurement equipment, the data interaction ability of each subsystem in the equipment is improved, and with the rapid development of the artificial intelligence technology such as deep learning, the image-based data processing and task understanding of the optical measurement equipment are added with more means. The dual driving of the demand and the technology progress makes the automatic upgrade of the optical measurement equipment imminent. However, the automatic operation is a system engineering, and not only the intelligent upgrade of each subsystem is required, but also the system needs to be continuously tested according to the task scene. A large amount of data accumulation is a necessary condition for improving the automatic operation ability. However, the target range measurement task has the actual situation that the task quantity is limited and the test cannot be performed in the actual combat. Therefore, the design of the optical measurement equipment automatic operation test method and system becomes an important factor for ensuring the effect of the automatic research and development.

[0004] The current scheme for the automatic operation of the optical measurement equipment is mainly for the satellite monitoring task, and the automatic operation scheme for the target range optical measurement task of the rocket, missile launching and landing observation scene is still in the initial stage. A few schemes only give the automatic operation process for a single scene, but do not give the test method and system construction of the system automatic operation. The pure use of the target range task data for testing has the problems of single tracking process, inability to verify the processing ability of the abnormal situation, and inability to exert the maximum efficiency of the automatic operation. If the simulation data is used, there is a large deviation between the simulation scene and the actual scene, and too much process is tested without paying attention to the performance improvement. The automatic of other optical measurement equipment task scenes, such as the automatic system calibration and the automatic space target test, although no system test method and scene are proposed, since the observation target is the satellite and the star, the test scene is easy to obtain and inconsistent with the task scene.

[0005] Specifically, Chinese patent document CN117148873A discloses a one-key automatic tracking system and method for light measurement equipment, which is an attempt to automatically operate the target range light measurement equipment. However, the technical solution only describes the implementation scheme of automation, and does not describe the method of how to test the function and performance during the system design process. The method does not reflect the performance improvement of the system through testing. Chinese patent document CN115390575A discloses a method and device for realizing automatic following of unmanned aerial vehicles based on ADS-B, which uses ADS-B to obtain target information and assists unmanned aerial vehicles to complete long-distance following of targets. However, this method is not for light measurement equipment, and the use of ADS-B data is only as a data source for following unmanned aerial vehicles, and does not fully utilize the performance of the system by testing the target and ADS-B. Other methods for automatic operation of light measurement equipment include Chinese patent document CN113566848A, which discloses a light measurement equipment automatic star calibration method and system based on a Loongson platform, and Chinese patent document CN110926501A, which discloses an automatic calibration method, system and terminal equipment for light measurement equipment. These methods are all automatic calibration of the system, which can complete testing and verification work relying on stars, and are not for target range scenarios. SUMMARY

[0078] The application idea of the application is:

[0079] In view of the requirement of the test method and system construction of the system automatic operation, the ADS-B-based optical measuring equipment automatic operation test method and system of the application greatly restores the data flow direction in the task scene and task process, guarantees the consistency of the test scene and the task scene in processing data of each subsystem, and has a smaller requirement on the test site, and only needs to be arranged at a place in a city where the airport plane taking off and landing can be observed.

[0080] The application will be further described in detail below in combination with the drawings and specific embodiments.

[0081] The application provides an ADS-B-based optical measuring equipment automatic test method and system based on ADS-B data as guidance and taking civil aviation planes as real-time observation targets. The test system provides a test environment in a real scene, and the system composition is as follows: Figure 1As shown, it comprises: an antenna, an ADS-B receiving device, a comprehensive test control computer, a time system, a storage device and a network switch.

[0082] The antenna is responsible for receiving the ADS-B message sent by the surrounding target aircraft and transmitting the received electromagnetic wave signal to the ADS-B receiving device. The antenna works at 1090MHz frequency band, and uses radio frequency receiving technology to capture the ADS-B data broadcasted by the nearby target aircraft to obtain the flight state information of the target aircraft.

[0083] The ADS-B receiving device receives the ADS-B message periodically sent by the target aircraft in real time through the antenna. The device is composed of a tuner, a filter, an analog-to-digital converter and other components, and also integrates a programmable logic device and a microcontroller inside. The message information in the ADS-B message contains flight state information, which includes the position information, height, speed, heading and unique identification number of the aircraft. The message information is sent to the comprehensive test control computer.

[0084] The comprehensive test control computer is responsible for processing all data inside the test system, including receiving the message information sent by the ADS-B receiving device and analyzing the target position information, receiving the image and data information of the optical measurement equipment, receiving the time information and trigger synchronization signal of the time system. At the same time, it is responsible for process control to ensure the smooth progress of the test, and provides an evaluation interface for automatic operation of the test project.

[0085] The time system provides trigger synchronization signal and time information for the test system.

[0086] The storage device completes the real-time storage of the target position information and the optical measurement equipment data, which is convenient for further testing of this type of tracking situation.

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

[0088] In the optical measurement equipment automatic operation test system based on ADS-B of the application, the system data flow is as shown in Figure 2 The test method suitable for the test system of the application comprises the following steps:

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

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

[0091] The integrated test control computer works under the driving of the timing trigger synchronization signal of the timing system, receives the timing information as a time reference, receives the image and data information of the optical measurement equipment (optoelectronic theodolite), and is used for realizing centralized processing of the test data.

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

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

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

[0095] According to the test requirement, all the data in the process can be stored for secondary test verification. The all data includes the image and data information of the optical measurement equipment (optoelectronic theodolite), and the target position information analyzed by the ADS-B receiving device.

[0096] The data flow of the optical measurement equipment automatic operation test system based on ADS-B of the application is compared with the external data flow of the actual target range optical measurement equipment as shown in Figure 3 From the data interface of the optical measurement equipment, it is found that the data type and flow direction provided by the optical measurement equipment automatic operation test system based on ADS-B of the application are completely consistent with the working process of the actual target range optical measurement equipment, so that the completeness of the test environment of the optical measurement equipment automatic operation test system based on ADS-B of the application is ensured, and the technical advantages are further embodied.

[0097] The working process of the optical measurement equipment automatic operation test system based on ADS-B of the application is as shown in Figure 4 The working process of the optical measurement equipment automatic operation test system based on ADS-B of the application is as shown in

[0098] When the automatic operation test is prepared to be carried out, it is ensured that the optical measurement equipment has been debugged and can carry out the automatic operation test.

[0099] The test system is started, the ADS-B receiving device works, the ADS-B message sent by the surrounding target aircraft is received through the antenna, the received electromagnetic wave signal is transmitted to the ADS-B receiving device, the message information is sent to the integrated test control computer in the form of UDP network after the signal is demodulated.

[0100] The integrated test control computer runs integrated test control software, and the integrated test control software receives a time as a time reference and triggers a synchronization signal. A target message analysis and selection module of the integrated test control software first decodes a large amount of target message information in a space according to a specified protocol, completely analyzes position information, height, speed, heading, a unique identification number and current packet time information of each aircraft, and displays the obtained flight state information in a tabular form. Due to the layout position of the optical measurement equipment, low-elevation targets are blocked by the surrounding environment, so the message analysis and selection module classifies each aircraft, and marks the observable target as green in front of the table and marks the unobservable target as red at the back of the table. According to the operation of the test personnel, one flight target is selected as a test target, and the position information of the test target is sent to the optical measurement equipment.

[0101] The optical measurement equipment currently enters an automatic operation mode, and after receiving the target position information, automatically processes the position information, controls the optical measurement equipment to search and capture the target. The test system judges whether the target is successfully captured and enters the automatic operation process according to the image and data information uploaded by the optical measurement equipment. If no target is found, a flight target (i.e. a target to be observed) is selected again, and the guidance data is forwarded to the optical measurement equipment. If the target is found, the real-time image system data information of the optical measurement equipment is received, and the image and data information uploaded by the optical measurement equipment are analyzed and processed. The process of analysis and processing is described below.

[0102] The optical measurement equipment automatic operation test system based on ADS-B of the present application reserves a plurality of automatic operation index test interfaces, including:

[0103] According to the image information, an automatic light adjustment, focus adjustment and zoom adjustment display and evaluation interface is provided.

[0104] According to the data information, an external guidance data processing and target tracking stability evaluation interface is provided.

[0105] According to the image and data information, a target extraction position correctness evaluation interface is provided.

[0106] According to the data information, an automatic process test is performed to check the correctness of data storage, data generation, data analysis and arrangement, data uploading and other steps.

[0107] After the test is completed, whether the data of this time is recorded is determined. If yes, the target position information and the optical measurement equipment image and data information are recorded, and the test is ended. If no, the test is directly ended.

[0108] As a test platform, the comprehensive test control software adopts modular design, each module is independently run in a private thread, and various data information completes standardized interface design, and the evaluation algorithm supports dynamic upgrade.

[0109] When the automatic test is finished, according to the requirements of a developer of a light measuring device to be tested, data in a test process can be standardizedly stored, so as to facilitate secondary test of an algorithm by each system.

[0110] The following will introduce in detail a plurality of automatic operation index test interfaces in the light measuring device automatic operation test system based on ADS-B.

[0111] The plurality of automatic operation index test interfaces reserved in the light measuring device automatic operation test system based on ADS-B define standard inputs and outputs of corresponding evaluation method definitions, including data elements, types and data formats.

[0112] The following will define data formats of the four types of evaluation interfaces respectively.

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

[0115] Output information of the interface: scores of various lens control effects measured by percentage, including light adjustment effect, focus adjustment effect and zoom effect.

[0116] 2. According to data information, an external guided data processing and target tracking stability are evaluated.

[0117] Input information of the interface: measurement data information and state information of each subsystem, data frequency is 100 Hz;

[0118] Output information of the interface: target tracking stability effect measured by percentage.

[0123] The input information of the interface: measurement data information and state information of each subsystem, data frequency 100Hz;

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

[0125] After decomposition, the standard interface type of the four types of evaluation interfaces in the ADS-B-based optical measurement equipment automation operation test system of the application includes: image and data two types. The output interface is a percentage score, and the percentage score result is a single type output, without detailed design.

[0126] The image and data two types of input interfaces in the ADS-B-based optical measurement equipment automation operation test system of the application are defined in detail.

[0127] 1、Image input interface definition:

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

[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] };

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

[0138] Color format adaptability: Use pixel format (PixelFormat) to represent the color type of the image, commonly grayscale (each pixel has one value, 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: Use the raw data pointer (data) to store image information, which points to the bit 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 state information, etc. The problems faced are the diversity of data types, the subsequent expansion of data quantity, and the problem of multi-platform adaptation.

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

[0147] name: The name or identifier of the data item, which helps to explain the meaning of the data.
