When the multi-channel synchronous that need realize different firework display handset is seted off, only need set the handset that needs to set off number, set off passage and set off the time in host computer interface.Then host computer interface sends to the discharge data set the second singlechip of conversion board circuit by serial ports, the second singlechip of conversion board first translates into single-chip microcomputer language it after receiving the information that host computer interface sends over, send after process, the identity information of recipient is contained in the information sent, if wireless form, directly be broadcast to all firework display handsets with the form of broadcast, then firework display handset can determine whether give up these data according to the identity information stored in native system single-chip microcomputer, therefore just selecting of only having identity to conform to accepts this information, if employing wired mode, then conversion board be passed to first set off handset while, instruction is just almost seted off handset to have received by second simultaneously, and then etc. pending data arrive second moment the 3rd of setting off handset and set off handset and go again to receive, so circulation is until all handsets of setting off all receive.
See Fig. 4, single firework display Air conduct measurement in the embodiment of the present invention in a firework display handset and the structural representation setting off circuit, it comprises by the data selector be connected with the first single-chip microcomputer, and an input pin of data selector connects one end of the 3rd resistance R3 resistance; First power vd D, the 5th resistance R5, the first diode D1, the 6th resistance R6 and fireworks igniter head are connected successively, the other end of the first diode D1 and the 6th resistance R6 series connection Node connectedness the 3rd resistance R3; Second source VCC, the 19 resistance R19, the second diode D2, electrochemical capacitor C3 mono-series arm; Second source VCC, 7th resistance R7,8th resistance R8 connects successively, the colelctor electrode of the other end connecting triode Q1 of the 8th resistance R8, the grounded emitter of triode Q1 also connects the negative pole of electrochemical capacitor C3, the base stage of triode Q1 connects one end of the 4th resistance R4, the other end of the 4th resistance R4 connects the first single-chip microcomputer, 7th resistance R7 is connected the grid of metal-oxide-semiconductor with the series connection end of the 8th resistance R8, the drain electrode of metal-oxide-semiconductor connects the series connection end of the first diode and the 6th resistance R6, and the source electrode of metal-oxide-semiconductor connects the series connection end of the second diode D2 and the 3rd electric capacity C3.Wherein VDD is 3.3V voltage, and VCC is 5V voltage.
Two-part content is contained in institute's diagram, first is the function of setting off, by the first Single-chip Controlling triode Q1 and MOS (Metal Oxid Semiconductor, mos field effect transistor) break-make of pipe Q2, electrochemical capacitor C3 is made to carry out discharge and recharge, time Q1 and Q2 turns off, electric capacity C3 is in charged state, the electric current flowing through fireworks igniter head is very little to be not enough to reach and to set off required current value, and now whether circuit can carry out setting off passage and detect normally; When needs are seted off, by the conducting of Single-chip Controlling Q1 and Q2, electric capacity C3 is sparked, what choose due to electrochemical capacitor C3 is the value that capacity is larger, conducting moment due to capacitance voltage can not transition, therefore this path can produce a larger electric current and flow to fireworks igniter head fireworks are seted off by igniting instantaneously.Second function is the detection of setting off passage, from the above mentioned, when Single-chip Controlling Q1 and Q2 turns off, the electric current produced by VDD can flow through the path of firework display, data selector can be arrived by this branch road at resistance R3 place the signal capture setting off passage, pass the first single-chip microcomputer after process back, the first single-chip microcomputer judges that this sets off the whether normal and not normal preliminary reason of passage.
In embody rule example, the specification of the 3rd electric capacity C3 is 3300uF/6.3V, is used for storaging current serve as the effect of " power supply " when needing igniting.First diode D1 and the second diode D2 is used to the moment prevented when metal-oxide-semiconductor Q2 is opened, and the reversing the current caused by the 3rd electric capacity C3 is excessive burns out battery design.Wherein the 5th resistance R5 and the 19 resistance R19 adds in order to current limliting.Two Current Limiting Diodes is 9014 models herein.The tie point of the 7th resistance R7 and the 8th resistance R8 has linked the G end of metal-oxide-semiconductor Q2, therefore these two resistance design in order to bias voltage Vg, because need setting off passage, whether normal need is monitored, add the data selector that 16 is selected 1, again because the restriction of this chip input current, so the 3rd resistance R3 is in order to give designed by data selector current limliting, what connect due to outer terminal JP1 is exactly set off passage, link outside fireworks igniter head, and the resistance of general electric igniter is smaller, the 6th this reference resistance of resistance R6 has just been added in order to obtain a certain amount of electric current.The function of this part is: after power supply electrifying, and the 3rd electric capacity C3 first charges (this process is very short), and then the first single-chip microcomputer goes by the shutoff of programming Control first triode Q1 the shutoff controlling metal-oxide-semiconductor Q2 then.When metal-oxide-semiconductor is closed time, 3rd electric capacity C3 charging is awaited orders, when needs are lighted a fire time, sending order by single-chip microcomputer makes metal-oxide-semiconductor open, at this moment the electric current be stored in the 3rd electric capacity C3 will be arrived the crossing of the 3rd resistance R3, the first diode D1 and the 6th resistance R6 by path by abrupt release, due to the 6th resistance R6 and igniter head resistance and backward resistance more than the 3rd resistance R3 and the first diode little, therefore most electric current can flow to this branch road of igniter head thus make electric igniter reach ' ignition point ' and light a fire.
In an embody rule example, data selector is multichannel data selector, has 24 pins, wherein the signal input of 16 pin supply sense channels, and 4 pins supply the first singlechip chip and realize channel selecting control.Such as CD4067BM selector has 24 pins, wherein 16 pins are the signal inputs supplying sense channel, have 4 pins to be that supply singlechip chip IC1 controls to carry out channel selecting, 4 passage binary representations can just be expressed as 16 kinds of situations, and to represent 16 different passages respectively selected.1 pin of CD4067BM chip exports, such as when igniter head passage is obstructed time, passing the signal of coming can lower than certain value, export a low level signal ' 0 ' after single-chip microcomputer judges and represent that this tunneling traffic is obstructed, otherwise then export ' 1 ', obtain the whether normal numerical value of a passage determined after selecting 1 data selector that 16 passages are detected (time compole short) one by one finally by 16, so just reach the object detecting ignition channel.
It is the physical circuit schematic diagram of the firework display handset of the another example of the present invention see Fig. 5, the basis of embodiment one adds a SR 1024 and a LED light 1025, this SR 1024 is connected on the radio receiving transmitting module of the first single-chip microcomputer 1021 and wired and radio communication circuit, in time pressing this SR, the first SCM program pointer performs from 0, and radio receiving transmitting module also can be initialised and then again start shooting; LED light, this indicator lamp is connected with single-chip microcomputer, when the first single-chip microcomputer is in wait state time, this LED light is in ' bright ' state always, when the first single-chip microcomputer receives the data command from conversion board time, no matter be wired mode or wireless mode, this LED light can be glimmered setting-up time continuously, as 1 second, indicate communication normal.
