Description

Technical Field

[0001] This invention relates to the field of selectors, and in particular to a distributed selector, a selection method, a selection device, and a medium. Background Technology

[0002] Signal selectors are typically used in air-to-ground communication systems. (See also...) Figure 1 A signal selector typically includes a selector host and a remote monitoring terminal. Existing selector hosts consist of N selector modules (1 to N), a central processing module, a control console module, and a power supply module. Each selector module provides a connection interface to a VHF radio (or VHF transmission system), and each selector module receives one VHF voice signal. Selector modules 1 to N correspond to N VHF voice signals. The main functions of the selector modules include: measuring parameters of the VHF radio's RX audio, performing delay processing on the VHF radio's RX audio, calculating the signal-to-noise ratio and noise level of the received signal, and outputting the VHF radio signal. The central processing module controls all selector modules in the system. It queries each selector module via an internal bus for the received signal-to-noise ratio, signal quality, COR signal (transmit command signal), and other information. It selects the selector module with the best signal quality and controls the voice signal received by that selector module to be output through the control console module. The control console module then outputs the received voice signal to a voice communication system or remote control.

[0003] In existing signal selectors, the central processing module actively queries information from each selection module and processes the information centrally to select the selection module with the best quality for communication. If the selection function of the central processing module fails, it will be unable to select the best selection module, affecting the operation of the entire signal selector and causing communication problems.

This information is then transmitted to other selection modules. The selection module with the highest SNR or the lowest noise level (i.e., the best signal quality) is selected as the optimal selection module. Each selection module has a distributed central processing function. After determining itself as the optimal selection module, it outputs its corresponding VHF voice signal. Compared to the centralized processing method using a central processing module, this distributed selection method reduces reliance on the central processing module. Even if the central processing module fails, the selection process remains unaffected, thus reducing fault nodes, improving the reliability of the signal selector, and ensuring smooth communication.

Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0044] Figure 3 This is an exemplary structural diagram of a distributed selector provided in Embodiment 2 of the present invention. Detailed Implementation

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] The purpose of this invention is to provide a distributed selector, selection method, selection device, and medium. By having each selection module independently calculate the signal-to-noise ratio or noise level of the received signal, the optimal selection module is determined to achieve the transmission of VHF voice signals. This reduces the dependence on the central processing module, thereby reducing fault nodes, improving the reliability of the signal selector, and ensuring smooth communication.

[0047] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] Example 1

[0049] Please see Figure 2 The distributed selector in this embodiment includes: a selector host; the selector host includes: N selection modules (selection module 1, selection module 2, selection module 3, ..., selection module N). The N selection modules are interconnected; each selection module receives one VHF voice signal (selection module 1 corresponds to VHF voice signal 1, selection module 2 corresponds to VHF voice signal 2, selection module 3 corresponds to VHF voice signal 3, ..., selection module N corresponds to VHF voice signal N); N > 1. The functions of each module in this distributed selector are as follows:

[0050] Any comparison module is used for:

[0051] It receives its own corresponding VHF speech signal and calculates its own reception information based on the received VHF speech signal; wherein, the reception information includes: signal-to-noise ratio or noise level; it receives the reception information of the remaining N-1 comparison modules; based on its own reception information and the reception information of the remaining N-1 comparison modules, it determines whether it is the best comparison module; wherein, the best comparison module is the comparison module with the highest signal-to-noise ratio or the lowest noise level; after determining that it is the best comparison module, it outputs its own corresponding VHF speech signal.

[0052] In this implementation, each selection module has a central processing function. After determining itself as the best selection module, it outputs its corresponding VHF voice signal. There is no need to set up a separate central processing module. Therefore, it can reduce fault nodes, improve the reliability of the signal selector, and ensure smooth communication.

[0053] As an optional implementation, the comparison module includes: a comparison unit and a central processing unit.

[0054] The selection unit is used to: receive its own corresponding VHF voice signal and calculate its own reception information based on the received VHF voice signal; receive the reception information of the selection units in the remaining N-1 selection modules; determine whether it is the best selection module based on its own reception information and the reception information of the remaining N-1 selection units; and establish a communication connection with the central processing unit after determining that it is the best selection module.

[0055] The central processing unit is used to: after establishing a communication connection, control the selection unit in the optimal selection module to output the received VHF voice signal.

[0056] In other embodiments of the present invention, the comparison module, in determining whether it is the best comparison module based on its own received information and the received information of the remaining N-1 comparison modules, may also be specifically used for:

[0057] The module compares its own received information with the received information of the remaining N-1 comparison modules to determine whether its own received information satisfies the requirement of having the highest signal-to-noise ratio or the lowest noise level among the N comparison modules; if so, it determines itself as the best comparison module.

[0058] In other embodiments of the present invention, the selector host further includes a console module.

[0059] The selection module is connected to the communication voice system or remote control via the console module.

[0060] The comparison module is further configured to: establish a communication connection with the console module after determining itself to be the best comparison module.

[0061] The console module is used to: after establishing a communication connection with the optimal selection module, output the VHF voice signal received by the optimal selection module to the communication voice system or the remote control.

[0062] Considering extreme cases, suppose one selection module (referred to as module A) determines that its received information satisfies the highest signal-to-noise ratio (SNR) among N selection modules, while another selection module (referred to as module B) determines that its received information satisfies the lowest noise level among N selection modules. In this case, both module A and module B will establish a communication connection with the console module as the optimal selection modules. Alternatively, two modules may have the same maximum SNR or the same minimum noise level.

[0063] In the extreme cases described above, multiple optimal comparison modules may emerge.

[0064] The console module can also be used to select one of multiple best comparison modules as the final best comparison module. Then, the final best comparison module can output the received VHF audio signal.

[0065] There are several selection methods, such as random selection, or selecting the module that meets the preset conditions as the final best comparison module.

[0066] Examples of preset conditions may include: the number of times a communication connection is established with the console module is the highest, or the number of times a communication connection is established with the console module exceeds a threshold, etc.

[0067] Furthermore, consider another extreme case: suppose only one selection module determines itself to be the best selection module, but that selection module malfunctions and cannot send a signal.

[0068] To address the problems encountered in the aforementioned extreme cases, in other embodiments of the present invention, any comparison module can be designed to perform the following operations:

[0069] After the best comparison module outputs the received VHF voice signal, it sends an output success notification to other comparison modules to inform them that the VHF voice signal output was successful.

[0070] In addition, any selection module also has the following functions:

[0071] If a module determines that it is not the best comparison module and does not receive a successful output notification within a preset time, it removes the receiving information of the best comparison module and re-determines whether it is the best comparison module.

[0072] For example, suppose there are 5 comparison modules. Each comparison module receives its corresponding VHF speech signal, calculates its own received information based on the received VHF speech signal, and then compares its own received information with the received information of the other 4 comparison modules to determine whether it is the best comparison module. Assuming that comparison module 2 has the highest signal-to-noise ratio, it becomes the best comparison module.

[0073] If the selection module 2 does not malfunction, after outputting the received VHF voice signal, the selection module 2 will send an output success notification to other selection modules.

[0074] If the selection module 2 suddenly malfunctions and is unable to send VHF voice signals, then selection modules 1, 3, 4 and 5 will not receive the output success notification.

[0075] If comparison modules 1, 3, 4, and 5 do not receive an output success notification within a preset time, the received information from comparison module 2 is discarded. Based on the received information from the remaining four comparison modules, each module re-determines whether it is the best comparison module. That is, it determines whether its received information meets the requirements of maximum signal-to-noise ratio or minimum noise level; if so, it determines itself as the best comparison module.

[0076] The preset time can be 0.5 seconds, 0.1 seconds, or even longer or shorter. Those skilled in the art can design it flexibly as needed, which will not be elaborated here.

[0077] Alternatively, a register can be designed to store data that, when set to the first value, indicates successful output, and when set to the second value, indicates output failure or no output. This register can be accessed by each comparison module, and the optimal comparison module modifies the data in the register to the first value after successful signal output.

[0078] After receiving a VHF voice signal, each selection module can start a timer. The timer duration is the preset time mentioned above. If the timer expires and the module is not the best selection module, it can access the register. If the data in the register is the second value, the received information of the best selection module can be removed, and the module can be re-determined to determine whether it is the best selection module.

[0079] In other embodiments of the present invention, the selector host further includes a power supply module and a remote monitoring terminal.

[0080] The power supply module is connected to N selection modules and the control console module to provide power to each module.

[0081] The remote monitoring terminal is connected to the selector host; the remote monitoring terminal is used to monitor the working status of the selector host. For example, the remote monitoring terminal can monitor in real time whether the selector module, control console module, and power supply module are malfunctioning, and can also control the optimal selector module to directly output the received VHF voice signal when the central processing module malfunctions.

[0082] Example 2

[0083] To further improve the reliability of the distributed selector, this embodiment, based on the above embodiments, adopts a redundant deployment for the console module.

[0084] Please see Figure 3 The console module includes a main console module and a backup console module; the main console module and the backup console module serve as backups for each other.

[0085] The aforementioned redundant design of the console modules ensures that if one console module fails, the other console module can continue to operate as a backup, thereby guaranteeing uninterrupted communication and higher reliability.
