Description
Technical field
The utility model relates to a kind of remote control, especially a kind of Remote Firing Unit.
Background technology
Double-voice cracker has another name called double-bang firecracker, be most important in the fireworks and firecrackers also be modal a kind of, set off through occasions such as the red-letter day of being everlasting, celebrations.Traditional mode of setting off double-voice cracker is generally all undertaken by manually lighting fuse cord, because the people directly contacts with double-voice cracker, therefore security is relatively poor, and annual much personal injury accidents that cause because of improper setting off that all can take place are to particularly children's the very big threat of safety formation of people.Around how safety is seted off double-voice cracker, many safe device for lighting have appearred at present,, basic thinking all is by double-voice cracker being fixed in the device that plays fixing, guide effect, thereby the double-voice cracker of setting off is flown to fixing direction, thereby reduce the danger that double-voice cracker is hurted sb.'s feelings.For example, application number is that the Chinese utility model of 200920113647.X has proposed a kind of safe device for lighting, and it is made up of stack shell and underframe, and the lead-in wire perforate is set on stack shell, because the existence of stack shell, thereby can effectively avoid the risk that double-voice cracker can not Vertical Launch after igniting.Obviously, foregoing invention in use still needs people and double-voice cracker close contact, so the raising of security is very limited.
The utility model content
Analyze by weak point above-mentioned safe device for lighting, if we find and can just can realize lighting a fire in larger distance, set off the danger that double-voice cracker produces and can reduce greatly.
The purpose of this utility model provides a kind of Remote Firing Unit that is used for existing double-voice cracker safety device for lighting, thereby makes people light double-voice cracker by long-distance remote control.
The utility model is achieved by the following scheme:
A kind of Remote Firing Unit that is used for double-voice cracker safety device for lighting comprises signal emission part and signal receive section, it is characterized in that: described signal emission part comprises power supply, encoder, wave generator circuit and signal transmission circuit; Signal receive section comprises power supply, signal receiving circuit, decoder, igniter circuits for triggering and igniter; The coding that is provided with in encoder and the decoder is identical.
Signal receive section is fixed on the existing double-voice cracker safety device for lighting, and the position that igniter position and double-voice cracker safety device for lighting fuse cord are drawn is corresponding, the igniter one igniting fuse cord that can ignite; When setting off double-voice cracker, signal emission part is sent remote signal; Signal receive section is sent the firearm igniting of triggering signal trigger point by the igniter circuits for triggering after receiving remote signal; The igniter point fuse cord of double-voice cracker of igniting of fighting.
In the above-mentioned Remote Firing Unit, the master chip of encoder can use chip common on the market, and this chip is divided into transmission chip and receiving chip, and corresponding one by one, for example: MF-T1B, MF-T3B, JM2455, PT2262 etc.
Description of drawings
Fig. 1 is the circuit theory diagrams of the utility model specific embodiment signal emission part;
Fig. 2 is the circuit theory diagrams of the utility model specific embodiment signal receive section.
The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is elaborated:
The circuit theory of the signal emission part of present embodiment as shown in Figure 1, wherein 101 is master chip, can send the waveform of signal according to the characteristics design of chip, can also encode, the unique coding of one cover is all arranged between each transmission and the receiving equipment, so the corresponding receiver of transmitter is selected the PT2262 chip in the present embodiment; 102 is wave generator circuit, and according to the difference of master chip, wave generator circuit has certain difference; 103 is code switch, and the coding set of code switch is identical with the coding of encoder in the receiving circuit herein; 104 is light emitting diode, plays indicative function; 105 (inductance), 106 (inductance), 107 (electric capacity), 108 (electric capacity) are signal transmission circuit; 109 is triode, and signal is played amplification; 110 is the current limliting build-out resistor; 111 is the chip build-out resistor, according to the difference of chip and difference; 112 is power supply.
The code signal that coding chip PT2262 sends by: address code, numeric data code, synchronous code are formed a complete code word, after decoding chip PT2272 receives signal, after its address code is relatively checked through twice, the VT pin is just exported high level, meanwhile corresponding data pin is also exported high level, if transmitting terminal presses ﹠ hold always, coding chip also can be launched continuously.When emitter does not have button to press, PT2262 disconnects power supply, its 17 pin is a low level, so the high frequency transmission circuit of 315MHz is not worked, when button is pressed, PT2262 gets electric work, its the 17th pin is exported modulated serial data signal, when 17 pin are the high frequency transmission circuit starting of oscillation of 315MHz between high period and launch the constant amplitude high-frequency signal, the high frequency transmission circuit failure of oscillations of 315MHz during 17 pin are for low putting down, so high frequency transmission circuit is controlled by the data signal of the 17 pin output of PT2262 fully, to be equivalent to modulation degree be 100% amplitude modulation thereby high-frequency circuit is finished amplitude keying (ASK modulation).
The circuit theory of the signal receive section of present embodiment as shown in Figure 2, wherein 201 is signal receiving chip, adopts the PT2272 chip match with coding chip PT2262 in the present embodiment; 203 is code switch, and the coding of code switch setting herein is consistent with the coding that sends the code switch setting; 204 for amplifying demodulator, selects SBX1610 in the present embodiment for use, certainly, for example BA5302 etc. other amplify the integrated device of demodulation and also can use; 205 is double D trigger; 206,207 is the build-out resistor of triode 208, according to amplifying signal that demodulator 204 the sends signal magnitude selection resistance with signal receiving chip 201 needs; 208 play the amplification inverting function for triode; 209 filter shapes of electric capacity; 210 is build-out resistor; Resistance 211 is the build-out resistor of signal receiving chip 201, the resistance different according to the chip different choice; 212 is filter capacitor, is the peripheral components of Voltage stabilizing module 218; 213 is build-out resistor; 214 is the current limliting build-out resistor; 215 is triode, utilizes its conducting---use as electronic switch by function; 216 is diode, prevents that oppositely big electric current from puncturing triode 215; 217 is relay, by 221 igniting of break-make control point firearm; 218 is Voltage stabilizing module; 219 is filter capacitor, is the peripheral components of Voltage stabilizing module 218; The 220th, relay contact; 221 is igniter; 222 is general supply.
After signal receiving chip 201 is received the modulation signal that signal emission part sends, after internal circuit is handled, from amplifying demodulator 204 outputs, after triode 208 amplifies paraphase, deliver to the DI end of signal receiving chip 201, decode when correct, D0～D3 end of D0～D3 end output and coding chip 101 (10 in corresponding diagram respectively, 11,12,13 pin) output signal is corresponding, and control circuit 205 is selected double D trigger for use, the D1 end links to each other with the Q1 end, CP whenever receives a positive pulse, and the signal of output Q1 just overturns once, triode 215 conductings → by → conducting, A point voltage step-down → uprise → step-down, relay 217 adhesive → disconnection → adhesives; After the relay conducting, igniter 221 power connections are also struck sparks, thereby light the fuse cord of double-voice cracker.
