Description

Technical Field

[0001] The present invention relates to the technical field of control systems, and in particular to an inflation controller and a control method for an emergency airbag of a drone falling into water. Background Art

[0002] With the rapid development of drone technology, drones are increasingly used in various fields, including aerial photography, logistics and transportation, agricultural monitoring, environmental monitoring, etc. However, drones face many risks during flight, especially when performing tasks in complex environments, such as flying over coastal areas, lakes, rivers or other waters. Once a malfunction or accident causes the drone to fall into the water, the security of its equipment and data will be seriously threatened. In summary, it is particularly important to develop an effective emergency protection device for drones falling into water.

[0003] At present, there are some protective measures for drones on the market, but most of them focus on anti-collision, obstacle avoidance, parachutes, etc. For emergency treatment of drones after falling into water, the existing technology has obvious deficiencies. Therefore, a method for emergency treatment of drones after falling into water is urgently needed. Summary of the invention

[0004] The purpose of the present invention is to provide an emergency airbag inflation controller and control method for a drone falling into water, aiming to ensure the safety of the drone after falling into water through automatic detection, rapid response and efficient inflation, and provide protection for subsequent rescue.

[0005] To achieve the above-mentioned objectives, the present invention provides an emergency airbag inflation controller for a drone falling into water, comprising a controller seat, a water fall detector interface, a self-locking button with light, a power interface and an igniter interface are arranged on the outside of the controller seat, a battery and a microcontroller are arranged inside the controller seat, the microcontroller is arranged at the bottom of the controller seat, and the battery is arranged above the microcontroller.

[0006] Preferably, the controller seat is in a rectangular parallelepiped structure, a controller cover is arranged above the controller seat, the controller seat and the controller cover match, and a silicone sealing pad is arranged between the controller seat and the controller cover.

[0007] Preferably, there are three water fall detector interfaces, which are respectively arranged on the left side, front side and right side of the controller base.

[0008] Preferably, there are two igniter interfaces, which are respectively arranged on the left and right sides of the controller base.

[0009] Preferably, the battery is a low-temperature lithium-ion secondary battery.

[0010] Preferably, the water drop detector interface is connected to a water detection sensor.

[0011] Preferably, the igniter interface is connected to the inflation trigger.

[0012] The present invention also provides a method for controlling the inflation of an emergency airbag of a drone falling into water, the steps comprising:

[0013] S1. Mount the controller on the drone and connect the water detection sensor and the inflation trigger through the igniter interface and the water fall detector interface;

[0014] S2, when the drone is started, the self-locking button with light is pressed, and the microcontroller performs a self-check on the controller, including checking the battery power and the inflation trigger;

[0015] S3, after the drone falls into water, the water detection sensor outputs a water fall signal, which is sent to the microcontroller through the water fall detector interface. After the microcontroller detects the signals transmitted by the three water fall detector interfaces, it outputs a high-level trigger signal of a certain duration through the two igniter interfaces;

[0016] S4. The inflation trigger receives the signal and quickly generates gas which enters the emergency airbag through the pipeline. After the inflation is completed, the drone floats on the water.

[0017] Preferably, in step S2, the microcontroller performs a self-check on the controller, including:

[0018] Detect the battery power. The microcontroller detects whether the battery power meets the cruising time requirement. If the power is sufficient, the microcontroller outputs the corresponding level to the green LED on the self-locking lighted button; otherwise, the microcontroller outputs the corresponding level to the red LED on the self-locking lighted button;

[0019] Detect the inflation trigger, the microcontroller measures the voltage difference between the two pins on the igniter interface. If the voltage difference is zero, the self-test passes, and the microcontroller outputs the corresponding level of the green LED on the self-locking illuminated button; otherwise, it is determined that the inflation trigger is not online, and the microcontroller outputs the corresponding level of the red LED on the self-locking illuminated button.

[0020] Therefore, the present invention adopts the above-mentioned drone water emergency airbag inflation controller and control method, which has the following effects:

[0021] (1) The microcontroller needs to detect the water falling signals sent by the three water falling detector interfaces at the same time to trigger the inflation trigger, thus avoiding false triggering;

[0022] (2) During use, the emergency airbag trigger controller is relatively independent of other drone systems and does not receive drone signal input. The trigger signal is automatically provided by the water detection sensor completely autonomously, and there is no electromagnetic signal leakage. It has independent working capabilities and prevents interference with the drone's working process.

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] Example

[0030] Reference Figure 1-2 The present invention provides an emergency airbag inflation controller for a drone falling into water, comprising a controller seat 1. The controller seat 1 is made of anti-corrosion material and is used to protect components. Mounting positions are arranged on both sides of the bottom. A water detector interface 2, a self-locking lighted button 3, a power interface and an igniter interface 4 are arranged on the outside of the controller seat 1. The self-locking lighted button 3 can display the self-test result and the battery power status. A battery 5 and a microcontroller 6 are arranged in the controller seat 1. The battery 5 is a low-temperature lithium-ion secondary battery used to provide operating energy for electronic equipment. The microcontroller 6 is arranged at the bottom of the controller seat 1, and the battery 5 is arranged above the microcontroller 6.

[0031] The controller seat 1 is a rectangular parallelepiped structure. A controller cover 8 is arranged above the controller seat 1. The controller seat 1 and the controller cover 8 match each other. A silicone sealing pad 7 is arranged between the controller seat 1 and the controller cover 8 for protection against falling into water.

[0032] There are three water drop detector interfaces 2, which are respectively arranged on the left side, the front side and the right side of the controller base 1. The water drop detector interfaces 2 are connected to the water detection sensor.

[0033] Two igniter interfaces 4 are provided, which are respectively provided on the left and right sides of the controller seat 1. The igniter interface 4 is connected to the inflation trigger.

[0034] The present invention also provides a method for controlling the inflation of an emergency airbag of a drone falling into water, the steps comprising:

[0035] S1. Mount the controller on the drone, and connect the water detection sensor and the inflation trigger through the igniter interface 4 and the water fall detector interface 2.

[0036] S2, when the drone is started, the self-locking light button 3 is pressed, and the microcontroller 6 performs a self-check on the controller, including checking the battery power and the inflation trigger. Whether the self-check passes or fails is indicated by the red or green LED on the self-locking light button 3 flashing at different frequencies or being always on. Specifically:

[0037] Detect the battery power. The microcontroller 6 detects whether the battery power meets the cruising time requirement. If the power is sufficient, the microcontroller 6 outputs the corresponding level of the green LED on the self-locking lighted button 3; otherwise, the microcontroller 6 outputs the corresponding level of the red LED on the self-locking lighted button 3 to prompt the user to pay attention.

[0038] To detect the inflation trigger, the microcontroller 6 measures the voltage difference between the two pins on the igniter interface 4. If the voltage difference is zero, the self-test is passed, and the microcontroller 6 outputs the corresponding level of the green LED on the self-locking illuminated button 3; otherwise, it is determined that the inflation trigger is not online, that is, the self-test fails, and the microcontroller 6 outputs the corresponding level of the red LED on the self-locking illuminated button 3 to prompt the user to pay attention.

[0039] S3. After the drone falls into water, the water detection sensor outputs a water fall signal, which is sent to the microcontroller 6 through the water fall detector interface. After the microcontroller 6 detects the signals transmitted by the three water fall detector interfaces 2, it outputs a high-level trigger signal of a certain duration through the two igniter interfaces 4.

[0040] Specifically, the microcontroller 6 reads the voltage difference between the two pins of the water detector interface 2. If the voltage difference between the two pins of the water detector interface 2 exceeds the set value, it means that the drone is operating normally; if the voltage difference between the two pins is lower than the set value, it is determined that the drone has fallen into the water. The two-pin voltage difference setting value is pre-written in the microcontroller 6 according to the working environment of the drone to meet the requirements of the drone cruising area, that is, above the sea surface environment or the lake surface environment.

[0041] The present invention needs to detect the water falling signals sent by the three water falling detector interfaces 2 at the same time before triggering the inflation trigger, thus avoiding false triggering;

[0042] S4. The inflation trigger receives the signal and quickly generates gas which enters the emergency airbag through the pipeline. After the inflation is completed, the drone floats on the water.

[0043] In specific use, the GPS positioning system can be used to assist in search and rescue of drones that accidentally fall into water during cruising. The GPS positioning system can quickly and effectively provide precise positioning information for emergency search and rescue of various aircraft that fall into water.

[0044] Therefore, the present invention adopts the above-mentioned drone falling into water emergency airbag inflation controller and control method, which ensures the safety of the drone after falling into water through automatic detection, rapid response and efficient inflation, and provides protection for subsequent rescue.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
