[0027] As shown in the attached Figure 1 to the attached Figure 3 As shown, the technical solution includes: a structural member, a control module, and a smoke generating module 8.

[0028] The structural member includes a housing 1, a connecting piece 9, and a bottom cover 2. The housing 1 and the bottom cover 2 are used as the loading structural members of the smoke generating module 8, which can ensure the structural safety during the operation of the control module and the smoke generating module 8. The connecting piece 9 adopts a C-shaped clamp structure, and the smoke indicating device is fixed inside the belly of the unmanned aerial vehicle through bolts. At the same time, a plurality of smoke outlets 3 are provided on the housing 1 and the bottom cover 2.

[0029] The control module mainly consists of a sealing cover 5, a circuit box 4, an ignition control circuit 6, etc.

[0030] The circuit box 4 is fixedly arranged on the end face of the housing 1. The sealing cover 5 is provided with a step. The ignition control circuit 6 is arranged on the sealing cover 5. At the same time, the ignition control circuit 6 is fixedly arranged inside the circuit box 4 and is connected to the plug 7 arranged on the sealing cover 5. The plug 7 is mainly used to connect to the power supply of the drone.

[0031] The ignition control circuit 6 includes a power module connected to the plug 7, an MCU system for processing and transmitting signals for the ignition control circuit 6, a communication circuit for receiving and sending signals with the drone, and an ignition circuit (including an ignition capacitor) connected to the smoke generating module 8.

[0032] The smoke generating module 8 includes an electric ignition tube, a central fire transfer tube, a smoke generating agent, etc. Among them, the electric ignition tube uses an insensitive ignition tube to generate indicating smoke by receiving the ignition current of the ignition control circuit 6.

[0033] Among them, the control module has functions such as communicating with the drone, detecting the voltage of the ignition capacitor, ignition, and self - disabling. Specifically as follows:

[0034] a) After power - on, the ignition control circuit 6 automatically completes system initialization;

[0035] b) After completing voltage conversion, the ignition control circuit 6 system completes self - inspection;

[0036] c) Feed back the real - time charging voltage to the drone and receive the unlocking instruction of the drone;

[0037] d) Before receiving the unlocking instruction, the ignition control circuit 6 system is in a locked state;

[0038] e) Receive the ignition signal of the drone and discharge to ignite the electric ignition tube;

[0039] f) Precise delay function, discharge to ignite the electric ignition tube.

[0040] The implementation process of this technical solution:

[0041] The smoke indicating device is installed in the belly of the drone through the connecting piece 9 as an independent component. The smoke indicating device itself does not have a power supply, and the power supply of its ignition control circuit 6 comes from the drone control system. During the stages of launch, climb, high - altitude cruise, high - altitude hovering, etc. of the drone, the smoke indicating device is in a power - off state, which can ensure the safety during the service and flight stages;

[0042] As shown in the appendix Figure 4 shown, during the operation of the drone, the cooperation and use process of the smoke indicating device and the drone is as follows:

[0043] 1. When the drone enters the target area and descends to the set height, the drone powers on the smoke indicator device. After the drone gives a charging signal, the ignition control circuit 6 in the smoke indicator device quickly completes the charging of its own working energy storage capacitor and ignition capacitor. The drone needs continuous power supply.

[0044] 2. After the ignition control circuit 6 is powered on, it will first initialize the system and continuously report the ignition capacitor voltage to the drone control every 1 second. After the system initialization is completed, the ignition control circuit 6 enters the locked state. In the locked state, the ignition control circuit 6 only retains the ignition capacitor charging voltage detection and communication functions with the drone control system, and the other I / O ports are closed. The ignition control circuit 6 will only release the locked state and enter the standby state after receiving the unlock command issued by the drone system.

[0045] 3. After the UAV has searched for the target, it sends a release command to the smoke indicator device. After receiving the release command, the ignition control circuit 6 in the smoke indicator device releases the lock and enters the standby state. The ignition control circuit 6 uses this as the timing zero point.

[0046] 4. The drone enters dive mode and approaches the target at a certain angle and speed.

[0047] Signal 1: When the UAV reaches the set altitude, the UAV sends an ignition signal to the smoke indicator device.

[0048] Signal 2: After receiving the unlocking signal, the ignition control circuit 6 in the smoke indicator device starts accurate timing and delays for the set time.

[0049] 5. After the ignition control circuit 6 in the smoke indicating device receives any ignition signal, the ignition control circuit 6 outputs an ignition current to ignite the electric ignition tube in the smoke module 8, and the electric ignition tube ignites the ignition powder in the central ignition tube. The ignition powder burns to produce high-temperature and high-pressure gas and flame, which breaks through the sealing aluminum foil and ignites the smoke agent at the same time. The colored smoke generated by the reaction of the smoke agent is ejected from the smoke outlet 3 and diffused into the air to form indicator smoke.

[0050] 6. When a fault occurs in the ignition process, the ignition control circuit 6 discharges the electric energy stored in the ignition capacitor after the drone control system no longer provides power for a set time, and loses the ignition capability.

[0051] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
