Description
Technical field
The present invention relates to circuit structures, are concretely the wireless firing circuits of fireworks and firecrackers.
Background technology
By setting off fireworks firecracker to congratulate be the traditional folk custom in China, and in a burning smoke red-letter day or special commemoration day
Since people are close apart from lead and fireworks and firecrackers when flower firecracker, it is easy to that safety accident occurs.Also have more at present
Because firecracker of setting off fireworks causes the report of accident.Therefore how point of safes combustion fireworks and firecrackers is the primary step for avoiding safety accident
Suddenly.
Invention content
The present invention provides a kind of wireless firing circuits of fireworks and firecrackers, can realize the igniting of fireworks and firecrackers at a distance and determine
When light a fire, and people may be located remotely from fireworks and firecrackers when lighting a fire, to avoid the generation of safety accident.
The wireless firing circuit of fireworks and firecrackers of the present invention has the monolithic being connect with bluetooth receiving module by input terminal
The output end of machine, microcontroller connects firing circuit, is connected with tungsten filament by Cascaded amplification circuit in the ignition circuit.
The lead of fireworks and firecrackers is in contact or is wound with tungsten filament, personnel have evacuated to home, pass through the indigo plants such as mobile phone
Tooth equipment sends control signal to bluetooth receiving module, after bluetooth receiving module receives control signal, passes through serial ports and list
Piece machine communicates, and microcontroller receives the Cascaded amplification circuit turn-on in control firing circuit after data, and tungsten filament is made to alive, fast
Speed heating tungsten filament, fireworks and firecrackers lead is lighted after the temperature of tungsten filament reaches ignition point.
Further, the Cascaded amplification circuit includes the first triode and the second triode of respectively NPN type,
In the base stage of the first triode connect the output end of the microcontroller, emitter connects the base stage of the second triode, the two or three pole
The emitter of pipe is grounded, and the collector of the first triode and the second triode connects tungsten filament jointly.
The duration of ignition is controlled in order to facilitate user, three control signals of microcontroller can also be corresponded to respectively
Button and reception button when connecting added-time button, subtracting.Button is wherein received to be used for timing ignition and pass through bluetooth receiving module
Igniting two ways switches over, and is then bluetooth sparking mode when reception button is located at " reception " state, otherwise is timing point
Fire.In timing ignition, corresponding add deduct can be carried out button to setting time by added-time button or when subtracting.
On this basis, the display port of microcontroller connects display screen, can show the information of user setting, conveniently look into
It sees.
Further, the reseting port of microcontroller connects reset key, when exception occur in user setting mistake or circuit
When, circuit can be resetted by reset key.
Further, the clock port of microcontroller connects crystal oscillator, and clock sequence is provided for entire circuit.
Various functions wherein in microcontroller in involved control program clearly in existing common equipment and/or
There is similar application in application program, is not the innovation place of the present invention.
The wireless firing circuit of fireworks and firecrackers of the present invention can be realized and carry out igniting and timing to fireworks and firecrackers at a distance
Igniting makes people, far from fireworks and firecrackers, effectively prevent the generation of safety accident in igniting.
Specific implementation mode with reference to embodiments is described in further detail the above of the present invention again.
But the range that this should not be interpreted as to the above-mentioned theme of the present invention is only limitted to example below.Think not departing from the above-mentioned technology of the present invention
In the case of thinking, the various replacements or change made according to ordinary skill knowledge and customary means should all be included in this hair
In bright range.
