Abstract
Description
Technical Field
[0001] This utility model relates to the field of radio telemetry and remote control technology, specifically to a safety control device for aircraft based on telemetry data. Background Technology
[0002] Aircraft safety control involves using various measuring instruments and equipment to monitor the aircraft's flight status in real time, and implementing safe handling measures for malfunctioning aircraft according to pre-set rules. This aims to protect ground targets such as residential areas and minimize the damage caused by malfunctioning aircraft. Therefore, the most important aspect of aircraft safety control is accurately assessing the aircraft's status.
[0003] Telemetry data contains crucial information such as the operational status of various subsystems within the aircraft and its real-time location, playing an irreplaceable role in assessing aircraft malfunctions and predicting impact points. Therefore, real-time analysis of telemetry data to scientifically determine the target's status is the prerequisite and foundation for effective target safety control.
[0004] Currently, aircraft safety remote control devices typically refer to ground-based radio safety control equipment used to issue corresponding safety control commands to remote, high-speed flying targets. However, to complete aircraft safety control tasks, it is not enough to rely solely on safety remote control devices that send safety control commands; a command and control center and a data processing center are also required. The safety control center is the command and management center of the safety remote control device and also the top-level management equipment in the multi-level management system of ground remote control equipment.
[0005] With the support of the central computer, the control console monitors safety information, makes safety judgments, generates remote control commands, and monitors the command transmission and execution. The data processing center processes telemetry data and transmits key parameters such as the operating status of critical sensors and subsystems inside the aircraft, flight position information, and predicted landing point to the command and control center's safety control console.
[0006] This results in the complexity of the interaction process and poor application efficiency of existing solutions. Therefore, there is an urgent need for a solution that can independently complete security control tasks without the command and control center, security console, and data processing center. Utility Model Content
[0007] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a telemetry data-based security control device that can independently complete security control tasks without the command and control center and data processing center.
[0008] This utility model provides a safety control device based on telemetry data, applied to a mobile vehicle. The vehicle is equipped with an antenna. The safety control device includes a telemetry baseband for receiving and demodulating telemetry data, a portable computer for automatically sending corresponding safety control commands based on parameter information in the telemetry data, and a clock device for time synchronization.
[0009] The telemetry signal is transmitted to the telemetry baseband via the antenna. The telemetry baseband is also connected to the clock device and the portable computer. The portable computer is pre-configured with parameters before use and is configured to automatically read the information recorded by the telemetry baseband when in use.
[0010] Furthermore, the telemetry baseband is an S-band telemetry baseband suitable for multi-band types; wherein, the multi-band types include radio frequency and intermediate frequency.
[0011] Furthermore, the antenna includes both omnidirectional and directional antennas.
[0012] Furthermore, the security control device also enables display control of the telemetry baseband via KVM or a combination of keyboard, mouse, and monitor.
[0013] Furthermore, the vehicle is also equipped with a signal transmission device, which is connected to the telemetry baseband; wherein the signal transmission device includes a splitter, a downconverter, and an intermediate frequency matrix switch.
[0014] Furthermore, the signal transmission device is connected to the telemetry baseband, specifically including:
[0015] When the telemetry baseband is an external radio frequency telemetry baseband, a splitter is used to separate one channel of the radio frequency signal received from the antenna and connect it to the baseband to realize the reception and demodulation of telemetry data.
[0016] Furthermore, the signal transmission device is connected to the telemetry baseband, specifically including:
[0017] When the telemetry baseband is an external intermediate frequency telemetry baseband, the radio frequency signal received from the antenna is converted into an intermediate frequency signal by a downconverter, and the intermediate frequency signal output by the downconverter is connected to the baseband to realize the reception and demodulation of telemetry data.
[0018] Furthermore, the signal transmission device is connected to the telemetry baseband, specifically including:
[0019] When the telemetry baseband is an external intermediate frequency telemetry baseband, the radio frequency signal received from the antenna is converted into an intermediate frequency signal by a downconverter and input to the intermediate frequency matrix switch. The intermediate frequency signal output by the intermediate frequency matrix switch is then connected to the baseband to realize the reception and demodulation of telemetry data.
[0020] Furthermore, the clock device employs a timecoder.
[0021] This utility model provides a security control device based on telemetry data. By integrating the functions of a traditional security remote control device, a command and control center, and a data processing center, it provides a solution for devices without telemetry baseband or whose telemetry baseband cannot be used normally due to special reasons to quickly acquire the ability to receive and demodulate S-band telemetry data, and to independently complete security control tasks without the command and control center and data processing center.
[0022] It also has the advantages of not changing the original equipment structure, not affecting the original equipment function, simple and reliable structure, small workload, and low modification cost. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0030] It should be understood that, when used in this specification and the appended claims, the terms "comprising" and "including" indicate the presence of the described features, integrals, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or collections thereof.
[0031] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. Furthermore, it should be understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items, and all possible combinations thereof.
[0032] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.
[0033] like Figure 1 As shown in the figure, the present invention provides a safety control device based on telemetry data, which is applied to a mobile vehicle. The vehicle is equipped with an antenna. The safety control device includes a telemetry baseband for receiving and demodulating telemetry data, a portable computer for automatically sending corresponding safety control commands according to the parameter information in the telemetry data, and a clock device for time synchronization.
[0034] The telemetry signal is transmitted to the telemetry baseband via the antenna. The telemetry baseband is also connected to the clock device and the portable computer. The portable computer is pre-configured with parameters before use and is configured to automatically read the information recorded by the telemetry baseband when in use.
[0035] In this embodiment, the antenna includes an omnidirectional antenna and a directional antenna;
[0036] The clock device employs a clock coder;
[0037] The telemetry baseband is an S-band telemetry baseband suitable for multi-band types; wherein, the multi-band types include radio frequency and intermediate frequency.
[0038] It should be noted that the S-band telemetry signal sent by the target aircraft, which is used to demodulate the angle error signal to achieve automatic tracking, is received by the antenna and transmitted to the external telemetry baseband (i.e., the external baseband in the figure) to achieve simultaneous reception and demodulation of the angle error signal and telemetry data.
[0039] Connect the portable computer to an external telemetry baseband using a network cable, and use the portable computer to complete the work that was originally done by the command and control center's security console and data processing center;
[0040] The portable computer can automatically issue different safety control commands based on key parameter information in the aircraft's telemetry data; based on the commands, the device will send corresponding safety control commands.
[0041] In application, the vehicle is also equipped with a signal transmission device, which is connected to the telemetry baseband; wherein, the signal transmission device includes a splitter, a downconverter and an intermediate frequency matrix switch.
[0042] Reference Figure 2 The safety remote control device itself is capable of receiving S-band telemetry signals. These received S-band telemetry signals typically serve two purposes: first, to demodulate angular error signals, enabling the antenna to automatically track the aircraft target; and second, to receive and demodulate telemetry signals to obtain key target parameter information. The first purpose is a necessary capability for the safety remote control device, ensuring the antenna is always pointed at the target and can send safety control commands. The second purpose is not a necessary capability for existing safety remote control devices.
[0043] The telemetry baseband required by this solution is suitable for different types of S-band telemetry basebands, such as radio frequency (RF) and intermediate frequency (IF), with only minor differences in the external connection method, which does not affect the normal use of the baseband. Depending on the type of telemetry baseband (RF baseband, IF baseband) and the structure of the security remote control device, this solution provides three different connection methods:
[0044] Method 1: External RF Telemetry Baseband. A splitter is used to separate one channel of the RF signal received from the antenna and connect it to the baseband for telemetry data reception and demodulation. The time signal output from the timecoder is connected to the telemetry baseband for time synchronization. A KVM switch or a combination of keyboard, mouse, and monitor is used to control and display the telemetry baseband. Figure 3 .
[0045] Method 2: External IF telemetry baseband. The RF signal received from the antenna is converted to an IF signal by a downconverter. The IF signal output from the downconverter is then connected to the baseband to achieve telemetry data reception and demodulation. The time signal output from the timecoder is connected to the telemetry baseband to achieve time synchronization. A KVM switch or a combination of keyboard, mouse, and monitor is used to control and display the telemetry baseband. Figure 4 .
[0046] Method 3: External IF telemetry baseband. The RF signal received from the antenna is converted into an IF signal by a downconverter and input to the IF matrix switch. The IF signal output from the IF matrix switch is then connected to the baseband to achieve telemetry data reception and demodulation. The time signal output from the timecoder is connected to the telemetry baseband to achieve time synchronization. A KVM switch or a combination of keyboard, mouse, and monitor is used to display and control the telemetry baseband, such as... Figure 5 .
[0047] KVM is an abbreviation for Keyboard, Video, and Mouse. A KVM device is a hardware device that can control multiple computers or servers using a single keyboard, mouse, and monitor.
[0048] The above solution integrates the functions of traditional security remote control devices, command and control center consoles, and data processing centers. It provides a solution for devices without telemetry baseband or whose telemetry baseband cannot be used normally due to special reasons to quickly acquire the ability to receive and demodulate S-band telemetry data, and to independently complete security control tasks without the command and control center console and data processing center.
[0049] It also has the advantages of not changing the original equipment structure, not affecting the original equipment function, simple and reliable structure, small workload, and low modification cost.
[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
