[0022] The specific implementation of the present invention is described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-2 As shown, the delayed ignition control module 20 is applied to a fire-fighting bomb dispensing device, which includes a host computer 10. The delayed ignition control module 20 includes:

[0024] The main control circuit 21 is connected to the host computer 10 for communication;

[0025] an ignition circuit 22, the ignition circuit 22 being configured to output an ignition signal during operation;

[0026] An energy storage circuit 23 is connected to the ignition circuit 22 and the main control circuit 21, and the energy storage circuit 23 is used to supply power to the ignition circuit 22 and the main control circuit 21;

[0027] The control end of the main control circuit 21 is connected to the ignition circuit 22 . The main control circuit 21 is used to receive an ignition control signal sent by the host computer 10 and control the operation of the ignition circuit 22 according to the ignition control signal.

[0028] The energy storage circuit 23 can be implemented using a capacitor. In this embodiment, the delayed ignition control module 20 uses the energy storage circuit 23 to store electricity. When the projectile leaves the launch device, that is, when the delayed ignition control module 20 is disconnected from the external power supply, the energy storage circuit 23 discharges to power the various circuits in the delayed ignition control module 20, so that the main control circuit 21 and the ignition circuit 22 can operate normally. In addition, wireless ignition is safer for the drone and personnel.

[0029] In one embodiment, the delayed ignition control module 20 includes:

[0030] a discharge switch circuit 24 , wherein a first end of the discharge switch circuit 24 is connected to the energy storage circuit 23 , a second end of the discharge switch circuit 24 is grounded, and a controlled end of the discharge switch circuit 24 is connected to the main control circuit 21 ;

[0031] The main control circuit 21 is used to output a discharge switch signal to the discharge switch circuit 24 to control the energy storage circuit 23 to discharge.

[0032] In this embodiment, the discharge switch circuit 24 can be implemented using any discharge switch circuit 24 capable of controlling the discharge of the energy storage circuit 23, such as a MOS transistor. It will be appreciated that the main control circuit 21 controls the discharge switch circuit 24 to conduct, causing the energy storage circuit 23 to discharge, thereby providing operating power to the main control circuit 21 and the ignition circuit 22. This allows the main control circuit 21 and the ignition circuit 22 to continue to operate normally even when the external power supply is disconnected.

[0033] In one embodiment, the delayed ignition control module 20 further includes:

[0034] a charging switch circuit 25, wherein a first end of the charging switch circuit 25 is connected to a power supply end, a second end of the charging switch circuit 25 is connected to the energy storage circuit 23, and a controlled end of the charging switch circuit 25 is connected to the main control circuit 21. When the charging switch circuit 25 is turned on, it is configured to connect to an external power supply to charge the energy storage circuit 23;

[0035] a voltage detection circuit 26, wherein a detection end of the voltage detection circuit 26 is connected to the energy storage circuit 23, and an output end of the voltage detection circuit 26 is connected to the main control circuit 21, and the voltage detection circuit 26 is used to detect the voltage of the energy storage circuit 23 and output a corresponding voltage detection signal;

[0036] The main control circuit 21 is used to control the charging switch circuit 25 to be disconnected when the voltage value corresponding to the voltage detection signal is consistent with the preset voltage value, and output a charging completion signal to the host computer 10.

[0037] Furthermore, the voltage detection circuit 26 includes a voltage-dividing resistor, one end of which is connected to the energy storage circuit 23 , and the other end of which is connected to the main control circuit 21 .

[0038] In this embodiment, when the main control circuit 21 receives a charging command sent by the host computer 10, the discharge switch circuit 24 is disconnected and the charging switch circuit 25 is turned on to connect the external power supply to charge the energy storage circuit 23; at the same time, the main control circuit 21 performs voltage detection on the energy storage circuit 23. When the voltage value corresponding to the received voltage measurement signal is consistent with the preset voltage value, that is, charging is completed, the charging switch circuit 25 is controlled to be disconnected to end charging, and a charging completion signal is sent to the host computer 10 to notify the host computer 10 that charging of the energy storage circuit 23 is completed.

[0039] In one embodiment, the main control circuit 21 includes a delay circuit, and the delay circuit is used to set the duration of outputting the ignition signal.

[0040] In this embodiment, the main control circuit 21 can be implemented by a low-power single-chip microcomputer. Accordingly, the delay circuit can be an internal timer of the single-chip microcomputer for timing. When the set output ignition signal duration ends, the single-chip microcomputer controls the ignition circuit 22 to provide an ignition signal to the fire-fighting bomb dispensing device, thereby making the fire-fighting bomb dispensing device work.

[0041] In one embodiment, the delayed ignition control module 20 further includes a wireless communication circuit, which is connected to the main control circuit 21 and is used to communicate with the main control circuit 21 and the host computer 10 .

[0042] In this embodiment, the wireless communication circuit can establish a communication connection between the main control circuit 21 and the host computer 10, so that the main control circuit 21 can transmit various data to the host computer 10 and receive control commands sent by the host computer 10.

[0043] The present invention also proposes a fire-fighting bomb dispersing device, which includes a host computer 10 and the above-mentioned delayed ignition control module 20; the specific structure of the delayed ignition control module 20 refers to the above-mentioned embodiment. Since the present fire-fighting bomb dispersing device adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0044] When the delayed ignition control module 20 in the present invention receives the parameter setting command issued by the host computer 10, it modifies the storage parameters inside the main control circuit 21; when it receives the parameter reading command, it transmits various data of the delayed ignition control module 20 to the host computer 10; when it receives the charging command, it disconnects the discharge switch circuit 24, disconnects the ignition circuit 22, turns on the charging switch circuit 25, and at the same time detects the charging voltage of the energy storage circuit 23, and feeds back the charging completion signal to the host computer 10 after charging is completed; when the host computer 10 receives the charging completion signal, it can send an ignition command; after the host computer 10 sends the ignition command, the external power supply of the delayed ignition control module 20 is disconnected, and the power supply of the entire delayed ignition control module 20 is provided by the energy storage circuit 23; at the same time, the internal timer of the main control circuit 21 starts timing, and when the delay time ends, the main control circuit 21 controls the ignition circuit 22 to provide an ignition signal to the fire bomb dispensing device, thereby making the fire bomb dispensing device work. It can be understood that when the projectile leaves the launch device, that is, when the delayed ignition control module 20 is disconnected from the external power supply, the energy storage circuit 23 supplies power to each circuit in the delayed ignition control module 20 so that the main control circuit 21 and the ignition circuit 22 can work normally. In addition, wireless ignition is safer for drones and staff.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
