[0028] In order to make the purpose, content and advantages of the present invention more clear, the specific implementation methods of the present invention are further described in detail below.

[0029] The invention proposes a smoke bomb launch control system with multiple launch modes, including a smoke bomb manual control and bomb quantity display module, a power supply circuit, a collection circuit, a main control circuit, and a smoke bomb firing circuit;

[0030] The smoke bomb manual control and bullet quantity display module can complete the smoke bomb launch mode selection and manual firing control input, including bullet quantity display circuit, smoke bomb bullet quantity selection knob, manual / automatic switching switch, single / multiple switching switch, and manual firing button; the bullet quantity display circuit collects the loading status of 8 smoke bombs, namely left 1, left 2, left 3, left 4, right 1, right 2, right 3, and right 4. When the smoke bomb is loaded in place, the negative pole of the light-emitting diode indicating the bullet quantity status in the bullet quantity display circuit is connected to the vehicle body ground, thereby lighting up the corresponding smoke bomb bullet quantity indicator light. When there is no bullet, the corresponding smoke bomb status indicator light is off. The manual / automatic switching switch is a button switch, which is turned on for automatic state and turned off for manual state. The single / multiple switching switch is a button switch, which is turned on for multiple state and turned off for single state. The manual firing button is a self-resetting switch. The smoke bomb bullet quantity selection knob is used to select the bullet quantity to be fired.

[0031] The power supply circuit is composed of a fuse, an anti-reverse connection protection diode, a filter capacitor, and a power module, and can provide a 9-36V input, a 24V output, and a 5V output. In order to improve the stability of the system, the power board of the present invention has input overvoltage, input reverse connection and output short circuit protection functions through diodes, voltage stabilizing modules, etc., and reliable power supply is achieved through DCDC. The power supply circuit can stably output DC24V and DC5V voltages. DC24V is used to power the smoke bomb firing circuit and the smoke bomb manual control and bomb quantity display module, and DC5V is used to power the acquisition circuit and the main control circuit.

[0032] The acquisition circuit is a typical optocoupler circuit, which can photoelectrically isolate the switch signals from the smoke bomb manual control and bomb quantity display module through optocouplers, convert them into phase digital signals, and then transmit them to the main control circuit for processing.

[0033] The main control circuit can process manual / automatic, single-shot / multiple-shot, bullet quantity, and manual firing information of smoke bombs. Under the manual single-shot working condition, the manual control and bullet quantity display module of the smoke bomb outputs the manual, single-shot, and bullet quantity selection switch quantities to the acquisition circuit for processing and then transmits them to the main control circuit. The main control circuit processes the information and outputs the corresponding control signal for the firing of the smoke bomb to the smoke bomb firing circuit; under the manual multiple-shot working condition, the manual control and bullet quantity display module of the smoke bomb outputs the manual, multiple-shot, and bullet quantity selection switch quantities to the acquisition circuit for processing and then transmits them to the main control circuit. The main control circuit processes the information and outputs the corresponding control signal for the firing of the smoke bomb to the smoke bomb firing circuit; under the automatic working condition, the manual control and bullet quantity display module of the smoke bomb outputs the automatic switch quantity to the acquisition circuit for processing and then transmits it to the main control circuit. At this time, the main control circuit processes the warning position information transmitted from the laser warning device, forms a smoke bomb firing strategy, and outputs the corresponding control signal for the firing of the smoke bomb. In addition, the main control circuit can also process the ammunition quantity information in real time, convert the ammunition quantity information transmitted from the acquisition circuit into CAN bus information and report it to the host computer for ammunition quantity display.

[0034] The smoke bomb firing circuit consists of one SG2803 chip and eight relays. The 2803 chip receives the smoke bomb control signal from the main control, converts the signal into a low-effective smoke bomb drive signal, and realizes the firing control of the corresponding smoke bomb. The smoke bomb firing circuit can convert the smoke bomb firing control signal from the main control circuit into a smoke bomb firing drive signal. The smoke bomb firing circuit consists of one SG2803 and eight relays. The SG2803 is an array of eight Darlington tubes. Since the minimum firing current of the smoke bomb is 1A, the Darlington tube has a higher gain and a lower saturation voltage drop, and can withstand larger currents and voltages, so it can provide sufficient driving capability to drive the relay to work.

[0035] A smoke bomb launch control method with multiple launch modes, characterized in that:

[0036] S1. The acquisition circuit collects the switch quantity information such as single shot / multiple shot, manual / automatic, manual firing mode of smoke bombs and the ground signal of smoke bomb loading from the manual control and bomb quantity display module of smoke bombs, converts the switch quantity information into digital signals and transmits them to the main control circuit for centralized processing;

[0037] S2. The firing modes of smoke bombs are divided into manual and automatic. When the manual working condition is selected and the single-shot mode is selected at the same time, any one of the 8 smoke bombs can be fired individually. When the manual working condition is selected and the multiple-shot firing mode is selected at the same time, a total of 7 firing modes can be realized, including left 1,2, left 3,4, right 1,2, right 3,4, left all at once, right all at once, and total firing. When the automatic firing mode is selected, the main control circuit can receive the warning position information from the laser warning through the CAN bus and generate a corresponding firing strategy.

[0038] S3, the main control circuit outputs the smoke bomb firing control signal to the smoke bomb firing circuit, and the smoke bomb firing circuit outputs the corresponding smoke bomb firing drive signal, thereby realizing the smoke bomb firing control in multiple modes.

[0039] The invention has clear principles and convenient control, and integrates manual firing, automatic firing and bullet quantity display of smoke bombs, and can meet the selection of single-shot and various combined firing modes under manual working conditions. At the same time, automatic firing and bullet quantity reporting can be realized through the CAN bus.

[0040] The present invention has strong expandability, and if the user needs, 8 smoke bombs can be expanded to 16, because the firing principle of the shrapnel shell is the same as that of the smoke bomb, and thus it can also be expanded to the firing control of the shrapnel shell.

[0041] The present invention solves the problem that a traditional smoke bomb control box can only realize multiple firing of two or more smoke bombs but cannot realize a single firing function of a smoke bomb.

[0042] 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 the scope of protection of the present invention.
