Description

Technical Field

[0001] The present invention relates to the technical field of cabin broadcast control, and more specifically, to a method, system, terminal and medium for cabin broadcast priority control of a civil aircraft. Background Art

[0002] Cabin passenger broadcasting is an important part of aviation services. It targets passengers on board and delivers important information such as safety, service, and weather to passengers. It can be divided into service broadcasting, safety broadcasting, weather broadcasting, important information broadcasting, welcoming speeches, flight information broadcasting, and safety inspection broadcasting. It aims to provide safety and service information and enhance passengers' flight experience.

[0003] At present, cabin broadcast information basically comes from three types of entities. The first type is cockpit broadcast (also known as captain broadcast), where the pilots in the cockpit mainly give welcome speeches, pre-takeoff instructions, and special situation notifications (such as turbulence); the second type is cabin broadcast (also known as crew broadcast), where the flight attendants mainly give boarding broadcasts, pre-takeoff safety checks, emergency broadcasts, and safety demonstrations; the third type is onboard equipment (such as entertainment systems) broadcasts, which mainly include boarding music, pre-recorded audio, and program audio. The prior art stipulates that passenger broadcasts have priority, and are divided from high to low according to the priority of cockpit broadcasts, flight attendant broadcasts, pre-recorded notifications, and boarding music. However, since these three types of sounds may appear in the aircraft cabin one after another during the entire flight from before takeoff to after landing, and even different sounds may exist at the same time in different locations (such as front and rear cabins, bathrooms), the priority control logic settings recorded in the prior art are relatively complex; in addition, when expanding the cabin broadcast, the overall priority control logic needs to be adjusted. When there are many types of cabin broadcasts, the adjustment and modification of the priority control logic is more difficult.

[0004] Therefore, how to study and design a civil aircraft cabin broadcast priority control method, system, terminal and medium that can overcome the above-mentioned defects is a problem that we urgently need to solve. Summary of the invention

[0005] In order to solve the deficiencies in the prior art, the purpose of the present invention is to provide a civil aircraft cabin broadcast priority control method, system, terminal and medium, which decompose the priority logic of the civil aircraft cabin broadcast switching control process according to the two perspectives of broadcast range and controlled object, and can quickly determine the audio transmission channel that needs to be controlled. When a new broadcast is added to the priority logic, there is no need to compare the priority of the new broadcast with the original broadcast one by one, and the method has strong scalability.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] In a first aspect, a method for controlling cabin broadcast priority of a civil aircraft is provided, comprising the following steps:

[0008] Collect the real-time broadcast information in the aircraft cabin and maintain an online broadcast list;

[0010] Filter out from the online broadcast list an online broadcast that overlaps with the broadcast range of the sound source end as the first broadcast;

[0011] Filtering out, from all first broadcasts, a broadcast whose priority of the controlled object is lower than the priority of the controlled object corresponding to the sound source end as the second broadcast;

[0012] Generate a corresponding control instruction according to the intersection range between the second broadcast and the broadcast range of the sound source end;

[0013] The second broadcast channel between the sound source terminal and all the controlled broadcast terminals within the corresponding intersection range is started according to the control instruction;

[0014] Receiving an audio output signal or an audio stop signal triggered by a sound source;

[0023] Furthermore, the method also includes:

[0024] Identify the actual control object at the sound source end from the broadcast gating request;

[0025] If the actually controlled object is different from the controlled object, the object with the smallest priority between the actually controlled object and the controlled object is selected for the second broadcast screening.

[0026] Furthermore, the method also includes:

[0027] Define key device IDs and distribute them to the broadcast network;

[0028] When the controlled broadcast end determines that the sound source end it uses is the captain / crew chief device: if the key device ID is inconsistent with its own ID, the captain / crew chief device will be downgraded to a general device, and the priority of the controlled object will be reduced simultaneously; otherwise, the original state will be maintained;

[0029] When the controlled broadcast end determines that the sound source end it uses is a general device: if the key device ID is consistent with its own ID, the general device is upgraded to a key device and the priority of the controlled object is increased simultaneously; otherwise, the original status is maintained.

[0030] In a second aspect, a civil aircraft cabin broadcast priority control system is provided, the system being used to implement a civil aircraft cabin broadcast priority control method as described in any one of the first aspects, comprising:

[0057] Embodiment 1: A method for controlling priority of cabin broadcasting in a civil aircraft, such as Figure 1 As shown, the following steps are included:

[0058] S1: Collects the real-time broadcast information in the aircraft cabin and maintains an online broadcast list;

[0059] S2: receiving a broadcast gating request triggered by the sound source, the broadcast gating request including the broadcast range and controlled object of the sound source;

[0060] S3: Filter out, from the online broadcast list, an online broadcast that overlaps with the broadcast range of the sound source end as the first broadcast;

[0061] S4: Filter out, from all first broadcasts, a broadcast whose priority of the controlled object is lower than the priority of the controlled object corresponding to the sound source end as the second broadcast;

[0062] S5: Generate a corresponding control instruction according to the intersection range between the second broadcast and the broadcast range of the sound source end;

[0063] S6: starting the second broadcast channel between the sound source terminal and all controlled broadcast terminals within the corresponding intersection range according to the control instruction;

[0064] S7: receiving an audio output signal or an audio stop signal triggered by a sound source;

[0065] S8: When the second broadcast channel is started, the controlled broadcast terminal corresponding to the sound source terminal is switched from a state of being connected to the first broadcast channel to a state of being connected to the second broadcast channel according to the audio output signal;

[0066] S9: When the first broadcast channel is started, the controlled broadcast terminal corresponding to the sound source terminal is switched from the state of being connected to the second broadcast channel to the state of being connected to the first broadcast channel according to the audio stop signal.

[0067] The controlled objects include but are not limited to the pilot, co-pilot, observer, chief purser, flight attendant and automatic control program; among them, the priorities of the pilot, co-pilot, observer, chief purser, flight attendant and automatic control program decrease in sequence.

[0068] It should be noted that the first broadcast channel is the channel to which the controlled broadcast terminal is connected for real-time playback. Every time a broadcast gating request is received, the online broadcast list and the first broadcast channel are updated.

[0069] The present invention also includes: if there is no online broadcast in the online broadcast list that intersects with the broadcast range of the sound source end, the broadcast channel between the sound source end and the broadcast end within the corresponding broadcast range is started, and the broadcast triggered by the sound source end is updated to the online broadcast list.

[0070] The present invention also includes: identifying the actual controlled object at the sound source end from the broadcast selection request; if the actual controlled object is different from the controlled object, selecting the object with the smallest priority between the actual controlled object and the controlled object for second broadcast screening.

[0071] The present invention also includes: defining a key device ID and issuing it to the broadcast network; when the controlled broadcast end determines that the sound source end used by itself is a captain / crew chief device: if the key device ID is inconsistent with its own ID, the captain / crew chief device is downgraded to a general device, and the priority of the controlled object is simultaneously reduced; otherwise, the original state is maintained; when the controlled broadcast end determines that the sound source end used by itself is a general device: if the key device ID is consistent with its own ID, the general device is upgraded to a key device, and the priority of the controlled object is simultaneously increased; otherwise, the original state is maintained.

[0072] For example, the sources of passenger broadcasts are divided into cockpit broadcasts, cabin broadcasts, and equipment broadcasts. Among them, cockpit broadcasts are divided into captain broadcasts, co-pilot broadcasts, and observer broadcasts according to their identities. These three types of broadcasts are cabin-wide broadcasts. Cabin broadcasts are divided into purser cabin-wide broadcasts, flight attendant cabin-wide broadcasts, purser zone broadcasts, and flight attendant zone broadcasts. Equipment broadcasts are divided into PRAM (pre-recorded broadcasts), VA cabin-wide broadcasts (entertainment broadcasts), and BGM (boarding music broadcasts). These three types of broadcasts are cabin-wide broadcasts, and there is also a VA zone broadcast (entertainment broadcast).

[0073] The priorities of the above-mentioned broadcast types are shown in Table 1.

[0074] Table 1 Broadcast priority

[0075]

[0076]

[0077] The cockpit broadcast is divided into four types according to the working status: idle (the state when the channel is not started), waiting (the state when only the channel is started but no audio output signal is generated), playing (the state when the channel is started and the audio output signal is generated), and suspended (the state of the second broadcast channel is switched to the state of connecting to the first broadcast channel). The states can be converted to each other. Figure 1 shown.

[0078] For example, the discrete signals that affect the cockpit broadcast are CNS_PAx_SEL (broadcast selection signal) and CNS_PAx_PTT (audio on / off signal), 0 is valid and 1 is invalid.

[0079] When the cockpit broadcasts, the CNS_PAx_SEL signal from the cockpit is received and the broadcast starts. The cabin chime is triggered and the PTT button on the handle is pressed to speak. A crew member (pilot / co-pilot / observer) presses PTT to make CNS_PAx_PTT effective, and the sound is played through the speaker, and the PA indicator light is on. Figure 2 shown.

[0080] During the broadcast process, if CNS_PAx_SEL of a higher priority member channel (ACP) is valid, the broadcast is terminated.

[0081] Cabin broadcasting is divided into four working states: idle, waiting, playing, and suspended. The states can be switched between each other. Figure 3 shown.

[0082] The signals that affect the cabin broadcast are the cabin handheld transceiver buttons, including PA (all cabin broadcast) / PA_AFT (rear cabin broadcast) / PA_FWD (front cabin broadcast). When the buttons are pressed, it is valid, and when the RESET button is pressed, it is invalid.

[0083] When the service area is broadcasting, the PA / PA_AFT / PA_FWD of a handheld transceiver is pressed to start the broadcast. At this time, the cabin chime is triggered, and the PA indicator light is lit to wait for the PTT button to be pressed to speak; the flight attendant presses the PTT of the handheld transceiver to play the sound through the speaker.

[0084] During the broadcast, if CNS_PAx_SEL in the cockpit is valid, this broadcast will be terminated; if PA / PA_AFT / PA_FWD with a higher priority in the cabin is pressed, this broadcast will be terminated.

[0085] Device broadcasting is divided into three types according to the working state: idle, play, and pause. The states can be converted to each other. Since the controlled object is an automatic control program, there is no waiting state, and the pause state is a transient state. Figure 4 shown.

[0086] The signals that affect device broadcasting are CHANNELx_KL, AUDIO_KL, and PARM_PAUSE.

[0087] When the device is broadcasting, receiving CHANNELx_KL or AUDIO_KL triggers the device broadcast, sends audio data to play, and indicates the type of audio played (PRAM / BGM / VA) through the AUDIO_TYPE message; at this time, when PARM_PAUSE=2 is received, the broadcast audio will be paused until PARM_PAUSE=1 resumes playback. The process conversion is as follows Figure 3 shown.

[0088] During the broadcast process, if the CNS_PAx_SEL in the cockpit is valid, this broadcast is paused until CNS_PAx_SEL is invalid; if the PA / PA_AFT / PA_FWD of the handheld transmitter and receiver is pressed, this broadcast is paused until RESET is pressed; if there is a device broadcast with a changed priority, the received AUDIO_TYPE type will be modified and the audio broadcasted by other devices will continue to be played.

[0089] After establishing the captain and chief steward priority for cockpit communication equipment and cabin telephones, the priority of their equipment use can be dynamically adjusted before takeoff to adapt to the position changes of important crew members. Figure 5 As shown, the specific method includes: a) defining a key device ID on the control panel and issuing it to the broadcast network; b) when the broadcast device determines that it is used as a captain / crew chief device, if the key device ID is inconsistent with its own ID, it is downgraded to a general device (simultaneously reducing the priority), otherwise it remains in the original state; c) when the broadcast device determines that it is used as a general device, if the key device ID is consistent with its own ID, it is upgraded to a key device (simultaneously increasing the priority), otherwise it remains in the original state.

[0090] Embodiment 2: A civil aircraft cabin broadcast priority control system, the system is used to implement a civil aircraft cabin broadcast priority control method as described in Embodiment 1, such as Figure 6 As shown, it includes an information collection module, a request receiving module, a broadcast screening module, a priority comparison module, an instruction generation module, a channel control module, a signal receiving module, a broadcast switching module and a broadcast recovery module.

[0091] Among them, the information collection module is used to collect the broadcast information played in real time in the aircraft cabin and maintain an online broadcast list; the request receiving module is used to receive the broadcast gating request triggered by the sound source end, and the broadcast gating request includes the broadcast range and the controlled object of the sound source end; the broadcast screening module is used to screen out the online broadcasts that have an intersection with the broadcast range of the sound source end from the online broadcast list as the first broadcast; the priority comparison module is used to screen out the broadcasts whose priority of the controlled object is less than the priority of the controlled object corresponding to the sound source end from all the first broadcasts as the second broadcast; the instruction generation module is used to generate the corresponding instruction according to the intersection range between the second broadcast and the broadcast range of the sound source end. a control instruction; a channel control module, used to start the second broadcast channel between the sound source end and all the controlled broadcast ends within the corresponding intersection range according to the control instruction; a signal receiving module, used to receive the audio output signal or audio stop signal triggered by the sound source end; a broadcast switching module, used to switch the controlled broadcast end corresponding to the sound source end from the state of connecting to the first broadcast channel to the state of connecting to the second broadcast channel according to the audio output signal when the second broadcast channel is started; a broadcast recovery module, used to switch the controlled broadcast end corresponding to the sound source end from the state of connecting to the second broadcast channel to the state of connecting to the first broadcast channel according to the audio stop signal when the first broadcast channel is started.

[0092] The present invention also records a computer terminal, which includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the program, a civil aircraft cabin broadcast priority control method as described in Example 1 is implemented.

[0093] The present invention also records a computer-readable medium on which a computer program is stored. The computer program is executed by a processor to implement a civil aircraft cabin broadcast priority control method as described in Example 1.

[0094] Working principle: The priority logic of the cabin broadcast switching control process of civil aircraft is decomposed from the two perspectives of broadcast range and controlled object, which can quickly determine the audio transmission channel that needs to be controlled. When adding a new broadcast in the priority logic, there is no need to compare the priority of the new broadcast with the original broadcast one by one, which has strong scalability.
