Description

Technical Field

[0001] This invention belongs to the field of aviation wireless communication, and specifically relates to a rack diversity scheduling method for a distributed integrated radio frequency architecture. Background Technology

[0002] The Communication Navigation Identification (CNI) system is an important component of the aircraft's avionics system, encompassing functions such as voice radio, data transmission, precision ranging, instrument landing, and air traffic control response.

[0003] The integrated radio frequency architecture combines various functional, independent devices into a single processing rack, receiving and transmitting signals via antennas on the fuselage's back and belly. These antennas are connected to power amplifier units located in the aircraft's equipment bay via radio frequency cables. The integrated processing rack then amplifies, attenuates, converts, filters, samples, and processes the radio frequency signals from each function into digital signals. Finally, the information calculated from the signals by each function is transmitted to the cockpit's display and control system via internal digital or fiber optic buses such as the 1553B and FC buses. These buses also serve as a conduit for issuing control commands to each function.

[0004] As the functions of aircraft communication, navigation, and identification systems continue to increase, the number of modules within the integrated processing rack also increases. This leads to larger rack size, weight, and power consumption, as well as more complex system management and maintenance. Furthermore, in large aircraft, processing various CNI functions on the same rack drastically increases the length of the RF cables connecting the integrated processing rack to antennas distributed throughout the aircraft, resulting in increased weight and significant RF signal transmission loss.

[0005] Therefore, in large aircraft, it is necessary to break down the single integrated radio frequency rack into multiple racks distributed in various locations on the aircraft, and configure the CNI function processing resources in the distributed racks according to the nearest antenna, that is, to adopt a distributed integrated radio frequency architecture.

[0006] In a distributed integrated RF architecture, each rack and its corresponding antenna have multiple independent receiving and transmitting capabilities for CNI functions. Therefore, compared to a centralized integrated RF architecture, a distributed integrated RF architecture needs to consider: 1. Avoiding different antennas transmitting the same function, which would cause signal confusion; 2. How to select the information obtained after each rack processes and calculates the same external signal; 3. Due to the obstruction of the aircraft body and changes in flight attitude, the signals that antennas at different locations on the aircraft body can receive vary and change in real time, requiring the selection of antennas without signal obstruction for receiving and transmitting. Summary of the Invention

[0007] This invention discloses a rack diversity scheduling method for a distributed integrated radio frequency architecture, which solves the problem of transmission chaos and inability to select a specific rack when existing racks have multiple transmit and receive functions.

[0008] This invention discloses a rack diversity scheduling method for a distributed integrated radio frequency architecture, comprising:

[0009] When waveform function i needs to be transmitted, the diversity scheduling platform distributes the service data parameters of waveform function i to N distributed racks; N is a positive integer; waveform function i can be any waveform function.

[0010] The diversity scheduling platform receives the pre-transmission switch sent by each distributed rack after receiving the service data parameters. It determines the first distributed rack for transmitting waveform function i in the state matrix and checks whether the first distributed rack is occupied. If not, it sends the pre-transmission switch of the first distributed rack back to the first distributed rack and sets the available status of the first distributed rack for waveform function i in the state matrix to occupied. If yes, it determines the second distributed rack for transmitting waveform function i in the state matrix, until all available distributed racks for waveform function i in the state matrix have been traversed.

[0011] The values ​​of the elements in the state matrix are used to indicate the availability of waveform functionality for the distributed rack.

[0012] Optionally, the rack diversity scheduling method for the distributed integrated radio frequency architecture also includes:

[0013] When the diversity scheduling platform receives waveform function i, it compares the signal amplitude of waveform function i uploaded by each distributed rack with the preset amplitude, and updates the availability status of each distributed rack for waveform function i in the status matrix according to the comparison result.

[0014] Optionally, update the available state of each distributed rack for waveform function i in the state matrix based on the comparison results, including:

[0015] When the signal amplitude of waveform function i uploaded by the distributed rack is less than the preset amplitude, the available status is set to unavailable;

[0016] When the signal amplitude of waveform function i uploaded by the distributed rack is not less than the preset amplitude and is not the maximum signal amplitude, the available status is set to available.

[0017] When the signal amplitude of waveform function i uploaded by the distributed rack is not less than the preset amplitude and is the maximum signal amplitude, the available status is set to priority use.

[0018] Optionally, the first distributed rack for transmitting waveform function i is determined in the state matrix, including:

[0019] In the state matrix, among the available states of N distributed racks for transmitting waveform function i, the distributed rack with the value that is used first is designated as the first distributed rack.

[0020] The second distributed rack for transmitting waveform function i is determined in the state matrix, including:

[0021] In the state matrix, among the N-1 distributed racks other than the first distributed rack, the distributed rack with any available value for transmitting waveform function i is designated as the second distributed rack.

[0022] Optionally, before updating the availability state of each distributed rack for waveform function i in the state matrix, the method further includes:

[0023] It is determined that at least one waveform function i uploaded by a distributed rack has a signal amplitude that is not less than a preset amplitude.

[0024] Optionally, before updating the available state of each transmitter rack for waveform function i in the state matrix, the method further includes:

[0025] Obtain the selected state of each distributed rack for waveform function i;

[0026] When the selected state is not selected, the available state of waveform function i for the unselected distributed rack in the state matrix is ​​directly set to unavailable.

[0027] Optionally, the rack diversity scheduling method for the distributed integrated radio frequency architecture also includes:

[0028] After the diversity scheduling platform sends the pre-transmission switch of the first distributed rack back to the first transmitting rack for a preset time, it restores the available state of the first distributed rack corresponding to waveform function i in the state matrix from occupied.

[0029] Optionally, the rack diversity scheduling method for the distributed integrated radio frequency architecture also includes:

[0030] The service data sent by the distributed rack with the largest signal amplitude from the diversity scheduling platform is sent to the display control system.

[0031] This invention discloses a rack diversity scheduling method for a distributed integrated radio frequency (RF) architecture. This method enables multi-rack compatible operation of waveform functions within the distributed integrated RF architecture, ensuring that waveform reception and transmission within the aircraft meet original specifications and avoiding conflicts arising from multiple signal transmissions and multiple computational information reports. It dynamically optimizes rack and antenna selection during flight, achieving unobstructed signal reception and transmission in various flight attitudes, and guaranteeing the stable use of various waveform functions in the CNI system. The rack diversity scheduling method proposed in this invention enables the implementation of a distributed integrated RF architecture. The use of a distributed integrated RF architecture avoids the design of large, heavy, and high-power integrated processing racks required in centralized integrated RF architectures, simplifying the design, management, and maintenance of processing racks and the onboard CNI system. Furthermore, the distributed integrated RF architecture optimizes the internal cabling layout, reducing signal attenuation and weight issues caused by long-distance RF cable transmission.

The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] The present invention will be further described in detail below with reference to embodiments, but the implementation of the present invention is not limited thereto.

[0040] like Figure 1-4 As shown, this invention provides a rack diversity scheduling method for a distributed integrated radio frequency architecture. The method provided by this invention employs the following... Figure 3 The distributed integrated radio frequency architecture system shown comprises antennas 1, 2, ..., N; distributed racks 1, 2, ..., N; and a diversity scheduling platform. N interconnecting cables connect the antennas and distributed racks, transmitting received and transmitted signals. Discrete lines connect the distributed racks and the diversity scheduling platform, transmitting control signals such as pre-transmission switches in real time. The specific number of discrete lines between each distributed rack and the diversity scheduling platform depends on the number of waveform functions that the antennas connected to the distributed rack can perform. N sets of fiber optic digital buses connect the distributed racks and the diversity scheduling platform, transmitting signal amplitude, calculation parameters, control commands, and other information at high speed. One set of fiber optic digital buses connects the diversity scheduling platform and an external display and control system, transmitting calculation parameters, control commands, and other information at high speed. N is a positive integer greater than 1.

[0041] Each distributed rack can run M independent waveform functions, such as Function 1, Function 2, ..., Function M. When the RF signal of a certain function meets the reception amplitude requirements, it can be received through the antenna and processed and calculated within the distributed rack. The transmit duty cycles of each function within the rack are relatively low, and the same antenna can be used through time-division multiplexing. M is a positive integer.

[0042] The rack diversity scheduling method for the distributed integrated radio frequency architecture provided by this invention includes receive scheduling and transmit scheduling.

[0043] Receive scheduling such as Figure 1 As shown, it includes the following:

[0044] Waveform function 1 in distributed racks 1, 2, ..., N processes the received digital signals, calculating the effective signal amplitude while generating service data, and then uploading it to the diversity scheduling platform via the fiber optic high-speed bus. The diversity scheduling platform summarizes the signal amplitudes of waveform function 1 uploaded from each distributed rack to obtain the received signal strength E1 = {E...} 11 E 12 ,…,E 1N}

[0045] Based on the waveform function 1, the sensitivity of the received signal is calculated, and the threshold value E of the received signal strength is set. th If E 1j <E th S 1j =0, the rack has no suitable signal input; if E 1j ≥E th S 1j =1, the rack can be used for receiving and transmitting; if E 1j =max{E 11 E 12 ,…,E 1N}, S 1j =2, this rack is used first.

[0046] Among them, S 1j E represents the availability status of waveform function i for the j-th distributed rack. ij This represents the received signal strength of the j-th distributed rack for waveform function i, where j is a positive integer from 1 to N and i is a positive integer from 1 to M.

[0047] Through the above transformation, the state of each rack at this moment is obtained as S1={S 11 ,S 12 ,…,S 1N Functions 2, 3...M obtain their respective states according to this method, and combine them to obtain the state matrix:

[0048]

[0049] Among them, S ij =0 indicates that it is not used, S ij =1 indicates that it can be used, S ij =2 indicates priority use, S ij =3 indicates that waveform i is using the antenna of rack j for transmission and cannot be used.

[0050] When rack 1, rack 2, ..., rack N respectively transmit the service data calculated by waveform function i back to the diversity scheduling platform, in S i ={S i1 ,S i2 ,…,S iN If S is a column query ij If the value is 2, then the service data of rack j is selected and sent to the display control system. The rack diversity scheduling method for the entire receiving process is as follows: Figure 1 As shown.

[0051] Launch scheduling, such as Figure 2 As shown, it includes the following:

[0052] When waveform function i needs to transmit, the display control system sends control command parameters to the diversity scheduling platform. The diversity scheduling platform distributes the service data parameters of waveform function i to rack 1, rack 2, ..., rack N via a fiber optic high-speed digital bus. Waveform function i in each rack generates a pre-transmission switch and a transmission baseband signal. The pre-transmission switch is sent to the diversity scheduling platform via a discrete line, serving as a transmission request signal from the distributed rack to the diversity scheduling platform.

[0053] The diversity scheduling platform queries the state matrix S in real time, and in S i ={S i1 ,S i2 ,…,S iN If S in column ij =2, then rack j serves as the transmitter rack for waveform function i (also known as the first distributed rack). Next, a transmit interlock check is performed, querying the state matrix S, where S... j ={S 1j ,S 2j ,…,S Mj} Check if there is an S in the row mj =3, if not, continue to the next step, forward the pre-emission switch of waveform function i back to rack j, and do not forward the pre-emission switches of other racks, where m is any integer from 1 to M except i; if there is S mj =3 indicates that the rack is transmitting other waveforms (i.e., waveform function m), and the diversity scheduling platform is in S i ={S i1 ,S i2 ,…,S iN} Check if column S exists in =1, if there is S in =1, then check if there is an S. mn =3, if there is no S mn =3, then rack n is the transmitting rack for waveform i, and the pre-transmission switch of waveform function i is forwarded back to rack n; the pre-transmission switches of other racks are not forwarded; if there is S mn =3, then return to the previous step at S.i ={S i1 ,S i2 ,…,S iN} Check if column S exists in =1, repeat the loop until all S in =1 If all queries fail to meet the conditions, the launch is closed and the launch will wait for the next launch.

[0054] When the diversity scheduling platform forwards the waveform function i pre-transmission switch back to rack j via discrete lines, it simultaneously sends S during transmission. ij Change to S ij =3, after launch, change back to the original value S ij =2 or S ij =1.

[0055] After receiving the pre-transmission switch for waveform function i, rack j performs subsequent digital-to-analog conversion and RF amplification of the baseband signal from waveform function i, and finally sends the RF signal from waveform function i to the antenna j corresponding to rack j for transmission. The rack diversity scheduling method for the entire transmission process is as follows: Figure 2 As shown.

[0056] When waveform function i has the function of using a specified antenna, the display control system sends control command parameters through the fiber optic high-speed bus. The diversity scheduling platform parses out the antenna selection command. The selected antennas a and b correspond to distributed racks a and b, respectively. Then, the state matrix S... i ={S i1 ,S i2 ,…,S iN} column S ia ,S ib The state parameters are obtained normally using the aforementioned method; the remaining S... ij =0 indicates that the selection is not selected and will no longer change with the strength of the received signal.

[0057] The waveform function i antenna selection command includes operating modes such as selecting one antenna m; selecting two antennas m and n; and selecting all antennas.

[0058] During power-on initialization, the diversity scheduling platform automatically loads the default antenna assignment value S for each waveform function. ij =2, the remaining antennas S ij =1.

[0059] The state matrix S is updated column-wise, that is, when the received signal state of waveform i changes, S... i ={S i1 ,S i2 ,…,S iN The column is updated to the new state, while the other columns remain unchanged.

[0060] The change in the received signal state refers to the situation where, during a certain signal reception, S in the state matrix... ij =2's position changes or S ij The number of 1s changes. At a certain moment, each rack receives no signal or the signal strength is below the received signal strength threshold E. th At that time, the state matrix S remains unchanged.

[0061] The antennas, arranged at multiple locations on the aircraft body, can achieve complete coverage of the signals transmitted by the aircraft to various airspaces.

[0062] The pre-transmission switch is a combination of low and high levels. The default power-on state is a high level. When waveform function i needs to transmit for a period of N microseconds, the waveform function pre-pulls the discrete line level low, creating a low-level window of N microseconds, before returning to a high level. After receiving the pre-transmission switch from each rack via the input discrete line, the diversity processing platform forwards the same N microsecond low-level window to the selected transmitter rack j via the output discrete line. The time difference between the input and output pre-transmission switches should remain constant to ensure the timing stability of the pre-transmission switches and the transmitted signals within the distributed racks.

[0063] In the distributed integrated RF rack, the number of waveform functions operating within each rack can be adjusted according to actual needs. The state S corresponding to the unused waveform function i within rack j is shown. ij =0.

[0064] The distributed integrated RF architecture uses at least 2×M×N discrete lines in discrete line groups, meaning that each waveform function within each rack requires one output and one input, totaling two discrete lines. If the number of waveform functions within the rack is reduced, the minimum number of discrete lines used is... Where K j The number of waveform functions after trimming within rack j.

[0065] refer to Figure 3This invention proposes an embodiment of a rack diversity scheduling method for a distributed integrated radio frequency architecture. It includes antennas A, B, C, and D located at four positions on the aircraft: upper front, lower front, upper rear, and lower rear. These four antennas are connected to distributed racks A, B, C, and D within the aircraft, respectively, via radio frequency cables. A diversity scheduling platform is located in the middle of the aircraft and is connected to distributed racks A, B, C, and D via four pairs of 40G fiber optic digital buses for transmitting information such as signal amplitude, calculation parameters, and control commands. The diversity scheduling platform is also connected to the display and control system via one pair of 40G fiber optic digital buses for transmitting calculation parameters and control commands. Each distributed rack hosts the same four waveform functions; therefore, each distributed rack is connected to the diversity scheduling platform via eight discrete lines for transmitting the pre-transmission switches for each waveform. The transmit duty cycles for waveform functions 1, 2, 3, and 4 are 1%, 1%, 1%, and 4%, respectively, enabling compatible operation within the same rack through time-division multiplexing.

[0066] In this embodiment, the number of racks is 4 and the number of waveform functions is 4, therefore the state matrix S is a 4×4 matrix:

[0067]

[0068] Among them, S ij =0 indicates that it is not used, S ij =1 indicates that it can be used, S ij =2 indicates priority use, S ij =3 indicates that waveform i is using the antenna of rack j for transmission and cannot be used.

[0069] 1. During power-on initialization, waveform 1 is loaded onto antenna C by default, waveform 2 is loaded onto antenna C by default, waveform 3 is loaded onto antenna D by default, and waveform 4 is loaded onto antenna A by default. Therefore, the state matrix S after power-on initialization is:

[0070]

[0071] 2. After the CNI system's various functions begin operating, each waveform function within the distributed rack receives signals. Within the diversity scheduling platform, waveform functions 1 from racks A, B, C, and D respectively process the received signals and transmit the amplitude information to the diversity scheduling platform via fiber optic digital buses. The diversity scheduling platform then determines the amplitude based on the signal strength of each rack's waveform function 1, for example, E = {750, 695, 175, 30}, and the set sensitivity threshold E. th =64, generate waveform 1 with state parameters S={2,1,1,0} at the current time, the state parameters are generated as follows. Figure 4 As shown. The state parameters of waveform 1 are updated in the state matrix:

[0072]

[0073] Similarly, waveform functions 2, 3, and 4 also synchronously update the state matrix based on the amplitude information transmitted back from each rack. The state matrix is ​​as follows:

[0074]

[0075] After waveform function 1 of racks A, B, C, and D is completed, the service data is transmitted to the diversity scheduling platform for aggregation via the fiber optic digital bus. For example, distance information {43.5km, 43.2km, 44km, no data}. The column containing waveform 1 in the current state matrix is ​​{2,1,1,0}. Therefore, rack A has the best signal reception status. The service data of rack A is selected: distance information 43.5km is uploaded to the display control system.

[0076] 3. When waveform function 1 needs to transmit, the display control system sends control command parameters to the diversity scheduling platform. The diversity scheduling platform distributes the service data parameters of waveform function 1 to racks A, B, C, and D via a high-speed fiber optic digital bus. Waveform function 1 in racks A, B, C, and D generates a 120-microsecond pre-transmission switch and a transmission baseband signal. The pre-transmission switch is sent to the diversity scheduling platform via a discrete line, serving as a transmission request signal from the distributed rack to the diversity scheduling platform.

[0077] The diversity scheduling platform queries the current state matrix S, S 1A =2, therefore rack A is selected as the transmitter rack for waveform function 1. Then, a transmit lockout check is performed, and the state matrix S is queried. 1A In the row {2,0,0,2}, there is no case where Sij=3. Therefore, the pre-emission switch for waveform function 1 is forwarded back to rack A, while the pre-emission switches for racks B, C, and D are not forwarded. Simultaneously, the state matrix S is updated. 1A =3:

[0078]

[0079] After the 120-microsecond pre-emission switch ends, the state matrix S is updated. 1A =2:

[0080]

[0081] 4. When waveform function 1 is transmitting, if waveform 4 also needs to be transmitted at this time, waveform function 4 in racks A, B, C, and D generates a 20-microsecond pre-transmission switch and a transmission baseband signal. The pre-transmission switch is sent to the diversity scheduling platform through a discrete line as a transmission request signal from the distributed rack to the diversity scheduling platform.

[0082] The diversity scheduling platform queries the current state matrix S.

[0083]

[0084] S 4A =2, therefore rack A is selected as the transmitter rack for waveform function 4. Then, a transmit lockout check is performed, and the state matrix S is queried. 4A The current row {3,0,0,2} does not meet the emission conditions. Query S again. 4B =1, select rack B as the transmitter rack for waveform function 4. Then perform a transmit lockout check and query the state matrix S. 4B In the row {1,1,2,1}, there is no case where Sij = 3. Therefore, the pre-emission switch for waveform function 4 is forwarded back to rack B, while the pre-emission switches for racks A, C, and D are not forwarded. Simultaneously, the state matrix S is updated. 4B =3:

[0085]

[0086] After the 20-microsecond pre-emission switch ends, the state matrix S is updated to S. 4B =1:

[0087]

[0088] 5. Waveform 3 has the function of using a specified antenna. The display control system sends control command parameters through the fiber optic high-speed bus. The diversity scheduling platform parses the antenna selection command as using antenna C. Then S 3A =0, S 3B =0, S 3D =0, the state matrix S is updated as follows:

[0089]

[0090] 6. In this embodiment, the time interval between the input and output of the pre-transmission switch of the diversity scheduling platform is set to 100ns to ensure that each waveform meets the response delay requirements.

[0091] The above description is merely a further embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed in the present invention, based on the technical solution and concept of the present invention, shall fall within the scope of protection of the present invention.
