Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0015] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "includes a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0016] See also Figure 1-2, describe the embodiments of the present invention in detail.

[0017] Embodiment: An aircraft slide pre-position indicator light with distance measurement and sound and light warning functions comprises a housing 1 and a lampshade 6, wherein the housing 1 is a plastic injection molded part. A main control circuit board 3, a lamp board 4, and a reflective bowl 5 are arranged inside the housing 1, wherein the main control circuit board 3 is fixed to the lower part of the inner cavity of the housing 1, the lamp board 4 is fixed to the inner cavity of the housing 1 above the main control circuit board 3, the reflective bowl 5 is fixed to the upper part of the lamp board 4, the lampshade 6 covers the upper part of the reflective bowl 5, the edge of the lampshade 6 is fixedly connected to the edge of the upper opening of the housing 1, and a distance detection sensor 7 is arranged on the lampshade 6.

[0018] In one specific embodiment: see Figure 2 As shown, the main control circuit board 3 includes a power management module 3-1, a control module 3-2, a buzzer 3-4, and a status indicator light 3-5.

[0019] The status indicator lights 3-5 are fixed on the light board 4, perpendicular to the control circuit board, to provide visual warning signals for the flight crew. The light board 4 is a rectangular light board.

[0020] The buzzer 3-4 is installed on the circuit board of the status indicator light 3-5 to provide a sound warning signal to the crew.

[0021] The control module 3-2 performs logic control and issues instructions to the buzzer 3-4 and the status indicator light 3-5, and monitors the distance detection wave sensor in real time, and analyzes and judges the sensor data. After receiving the instructions from the control module, the status indicator light and the buzzer send out visual or auditory alarm signals.

[0022] The distance detection sensor 7 is connected to the control module 3-2 through the driver 3-3. The distance detection sensor 7 adopts an ultrasonic sensor, which is embedded in the front side of the lampshade 6. The ultrasonic sensor is used to detect the distance between the crew or passengers and the cabin door or the cabin door handle in real time when the conditions are met. When the crew or passengers approach the cabin door, the distance measured by the ultrasonic sensor exceeds the set first threshold distance, and the indicator light flashes to send a visual warning signal. When the crew or passengers are close to the ultrasonic sensor or hold the cabin door handle, the indicator light is always high to send a visual warning signal, and the buzzer generates a continuous sound to send an auditory warning signal.

[0023] The power management module 3 - 1 is used to provide a stable power supply for the control module 3 - 2 , the buzzer 3 - 4 , the status indicator light 3 - 5 , and the distance detection sensor 7 .

[0024] In a specific embodiment: brackets 2 are provided on both sides of the housing 1, and the brackets 2 are used to fix the aircraft slide pre-position indicator light as a whole in the installation hole of the aircraft cabin door.

[0025] The aircraft slide pre-position indicator light with ranging and sound and light warning functions indicates the following main functions:

[0026] Distance measurement function: When the crew or passengers approach the cabin door, the distance between the person approaching the cabin door or the cabin door handle is detected, and the measured distance is transmitted to the control module;

[0027] Status indicator light function: When the crew or passengers approach the cabin door beyond the set distance, the status indicator light will send a visual warning signal;

[0028] Buzzer function: When the crew or passengers approach the cabin door to a certain distance, the buzzer in the slide arming indicator light will send out an audible warning signal.

[0029] The aircraft slide arming indicator light with ranging and sound and light warning functions will trigger visual and audible warnings when the following conditions are met.

[0030] The aircraft is powered on and in grounded condition.

[0031] The emergency slide lever has been placed in the preset state.

[0032] A crew member or passenger approaches the door or attempts to pull the door handle.

[0033] The warnings are divided into two levels according to the distance of the crew or passengers to the cabin door.

[0034] Level 1 indicator light warning: When a crew member or passenger approaches the cabin door unconsciously, and the ultrasonic sensor of the cabin door detects within 50 cm, the slide pre-position status indicator light flashes to send out a warning signal, prompting relevant personnel to stay away from the cabin door.

[0035] Level 2 indicator light alarm: When a crew member or passenger continues to approach the cabin door and is within 30 cm of the cabin door ultrasonic sensor, the alarm level is raised, the indicator light continues to flash to send out an alarm signal, and the buzzer sends out three short beeps as an auditory alarm signal.

[0036] This aircraft slide pre-position indicator with ranging and sound and light warning functions can enable the crew to quickly and accurately prepare and deploy the slide equipment in an emergency through simple visual and auditory warning signals, ensuring that cabin passengers can evacuate the aircraft quickly and safely. At the same time, under normal circumstances, it prevents crew members or passengers from accidentally opening the escape slide equipment, causing serious economic losses and aircraft delays. The aircraft slide pre-position indicator does not require operation, has a simple system structure, and is highly reliable.
