[0022] In order to make the technical solution and advantages of the present application clearer, the technical solution of the present application will be further described in detail in detail and in detail with reference to the accompanying drawings. It can be understood that the specific embodiments described here are only partial embodiments of the present application, which are only used to explain the present application, not to limit the present application. It should be noted that, for the convenience of description, only the parts related to the present application are shown in the accompanying drawings, and other related parts can refer to the general design. In the absence of conflict, the embodiments in the present application and the technical features in the embodiments can be combined with each other to obtain new embodiments.

[0023] It is used for voice communication among cabin crew members when wired communication is unavailable.

[0024] The present application includes a control panel, a photoelectric receiver, an emergency lighting lamp and a photoelectric sensor helmet, wherein the control panel includes a status selection switch, an emergency communication indicator light and an optical communication control chip; the photoelectric sensor helmet includes a light sensor, a control chip, earphones, a transmitter, a battery, a portable strobe light and an emergency communication switch.

[0025] The present application relies on visible light signals as information transmission media and realizes in-machine communication through photoelectric conversion. The emergency communication state can be activated by the main pilot pressing the state selection switch on the control panel, or by the emergency communication switch on the helmet.

[0026] Specifically, the state selection switch is installed on the control panel, and the control panel is installed on the aircraft control panel. When the pilot presses the state selection switch, the emergency communication indicator light is always on red. This state is applicable to the wired communication failure in the aircraft, and the passengers cannot communicate normally.

[0027] The emergency communication switch is installed on the left side of the photoelectric sensor helmet. When the pilot presses the emergency communication switch, the emergency communication is turned on.

[0028] The control panel controls the communication status of the passengers in the cabin and displays the status. Specifically, the status selection switch controls the communication status; the emergency communication indicator light displays the communication status; the optical communication control chip controls the status of the status selection switch and the emergency communication indicator light, and the status selection switch inputs a switch quantity signal to the optical communication control chip, and the optical communication control chip controls the emergency communication indicator light to stay on or flash frequently. The optical communication control chip can receive the communication electrical signal 1 transmitted by the photoelectric receiver, and after modulation and filtering, send out the communication electrical signal 2, control the emergency lighting to flash frequently, and send out a visible light communication signal.

[0029] The photoelectric receiver is installed on the top of the cockpit, work cabin and corridor, and can receive the stroboscopic signal emitted by the portable stroboscopic light, that is, the visible light communication signal, convert it into a communication electrical signal 1, and send the communication electrical signal 1 to the optical communication control chip.

[0030] The emergency lighting is installed on the top of the cockpit, work cabin and corridor, and can receive the communication electrical signal 2 sent by the optical communication control chip, flash according to the band of the communication electrical signal 2, and send out a visible light communication signal.

[0031] The photoelectric sensor helmet has the basic functions of a universal protective helmet, is equipped with headphones and a microphone inside, and can perform wired communication under normal working conditions. The top of the helmet is equipped with a light sensor, a control chip and a battery, an emergency communication switch is installed on the left side of the helmet, and a portable strobe light is installed on the right side.

[0032] Specifically, after the optical sensor receives the visible light communication signal of the emergency lighting, it converts the optical signal into a communication electrical signal 3, transmits it to the control chip, and after the control chip amplifies, filters, and shapes it, it outputs the communication electrical signal 4 to the earphone, and the earphone plays the voice;

[0033] The control chip receives the communication electrical signal 3 converted by the optical sensor, and amplifies, filters, and shapes the electrical signal to complete the detection, extraction, and judgment of the signal, and outputs the communication electrical signal 4 to the earphone. The control chip can also receive the communication electrical signal 5 input by the transmitter, and after processing the signal, output the communication electrical signal 6 to the portable strobe light;

[0034] The battery is dormant when the helmet's wired communication is normal, and it powers the light sensor, control chip, earphones, microphone, and portable strobe light after the wired communication is disconnected;

[0035] The headset can play voice;

[0036] The transmitter can receive calls;

[0037] The portable strobe light is installed on the right side of the helmet and is connected to the control chip and battery through wires. The wires can be extended, and the portable strobe light can be removed from the helmet and turned into hand-held by the pilot.

[0038] The working process of emergency communication in the cabin of a certain type of aircraft is as follows:

[0039] The cockpit, corridor and top of the working cabin in the cabin are each equipped with an emergency light and a photoelectric receiver. The cockpit panel is equipped with an emergency communication control panel, and all cabin occupants wear photoelectric sensor helmets.

[0040] When the in-flight wired communication fails and cannot communicate normally, the main driver presses the status selection switch on the emergency communication control panel, and the emergency communication indicator light on the panel turns red and stays on, indicating that the emergency communication system has been activated. At this time, the main driver makes a voice, and the helmet transmitter converts the voice into an electrical signal and transmits it to the helmet control chip. After the helmet control chip modulates the signal, it controls the helmet strobe light to strobe and outputs a visible light signal. After receiving the visible light signal, the photoelectric receiver on the top of the cockpit converts the optical signal into an electrical signal and transmits it to the optical communication control chip. After the optical communication control chip modulates the signal, it outputs an electrical signal to the emergency lighting to control the lighting to strobe. The other members' helmet optical sensors receive the visible light strobe signal emitted by the lighting, convert it into an electrical signal, and modulate it by the control chip and output it to the helmet earphone, which plays the voice of the main driver. Similarly, other passengers can form voice interaction with the main driver through the emergency communication system to realize emergency communication. A filtering module is also installed in the photoelectric sensor helmet, and the filtering module removes the part of the received communication electrical signal that is the same as the emitted communication electrical signal.

[0041] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
