This measure is further explained as follows:
1, in this measure, the oscillating unit of realizing change code is a very important part, designer has designed interlock circuit and has coordinated with it, the principle that forms vibration is: after opening power supply, PNP triode (03 in Fig. 1) has minute quantity electric current, the gesture that formation is opened, at this moment larger collector electrode becomes the base current of NPN triode (06 in Fig. 1), cause the open-minded of NPN triode, the reduction of its collector voltage, and the commissure electric capacity of NPN transistor collector and PNP triode (02 in Fig. 1) has formed strong positive feedback, its result causes the open-minded rapidly of PNP triode and rear NPN triode two pipes, two pipes present saturated shape, when commissure electric capacity electricity is full of, feedback finishes, , this pipe starts to change to cut-off direction, commissure electric capacity starts electric discharge in the other direction, its result reduces the bias current of PNP triode, the bias current of NPN triode reduces, owing to producing the reason of strong feedback, the cut-off simultaneously of two pipes, form first cycle of vibration, when the reciprocal current discharge of commissure electric capacity discharges, at this moment the gesture that becomes to open again because of the first pipe P pipe, in like manner produce second period, the 3rd cycle etc.Thereby alternately changing of output generation 1 and 0.
When first of commissure condenser type complementary type oscillating circuit is output as a high position, by the base resistance (08 in Fig. 1) of anti-phase triode, make anti-phase triode (09 in Fig. 1) conducting, the collector voltage of anti-phase triode reduces, if first of commissure condenser type complementary type oscillating circuit is output as low level, cannot make anti-phase triode conducting, so anti-phase triode cut-off, the current collection of anti-phase triode is very high-order, and the base resistance of anti-phase triode and collector resistance can adjust suitable numerical value very easily.
In foregoing circuit simple in circuits, less demanding to triode, because inclined to one side resistance under PNP triode has adopted the connect form of fixed resistance (07 in Fig. 1) with adjustable resistance (05 in Fig. 1), thus be very easily adjusted into the desired frequency of the person of establishing, and mate with whole circuit.Another feature of this circuit is that the resistance to height of triode can be used in and requires high circuit, thereby adaptive surface is very wide, has expanded transmitting field.
2, in measure, oscillating unit has formed such annexation with coding integrated circuit, and the coded portion of coding integrated circuit has been divided into two parts, and a part is the fixed code having connected in advance, and another part is the variation code being connected with oscillating unit.When manual operation is launched, oscillating unit vibration, the movable code of coding integrated circuit has just become 0 and 1 two states, and the integrated circuit of at this moment encoding just can only a kind of solid size transmitting become two kinds of outputs of dicode from former.By the excitation to modulating tube, reached the object of dicode modulate emission.
3, can in becoming code, realize can realize 1 with X code, or 0 and the principle of the conversion of X code be: electronic relay used in measure 1 is bidirectional analog switch, when vibration is output as a high position, the control end of the analog switch connecting is for high-order, at this moment switch connection, so when if change code is original and power line joins, now this code is high-order; When if the control end of analog switch is high-order, if when change code is original and ground wire joins, now this code is zero-bit; When if the control end of analog switch is low level, the contact of electronic relay disconnects, and no matter bit line is originally high-order, or zero-bit, and this code is suspended state, thus this become code when vibration, become all the time 1 with the variation suspending, or 0 and the variation of suspension.Fig. 3 in the accompanying drawings, described be realize 1 with the code conversion of X.
With above-mentioned change coding mode the same be the conversion of bit line of coding integrated circuit, when first of commissure condenser type complementary type oscillating circuit is output as when low, when second of commissure condenser type complementary type vibration is output as a high position, the control end of second the bielectron relay connecting is for high-order, at this moment switch connection, because the input termination of second electronic relay is low level, so bit line is low level, i.e. said 0 state; When if the control end of second electronic relay is low level, second electronic relay disconnects, bitline state does not now have and ground wire joins, and the output of electronic relay does not join with input, is suspended state, this bit line is also suspended state, so this bit line when vibration become all the time 0 with the variation suspending, Fig. 3 in the accompanying drawings, described be realize 0 with the cyclical-transformation of X, as connected second electronic relay by measure 3, can realize 1 with the cyclical-transformation of X.
The bidirectional analog switch (016 in Fig. 1) using in measure 1 is CD4066, when control end adds high level, and switch conduction, conduction impedance is lower, and in addition, conduction impedance is substantially constant in whole input reference signal.Eliminated the variation of switching transistor threshold voltage with input signal, therefore within the scope of whole working signal, conduction impedance is lower.Compare with single channel switch, have that input signal peak voltage ranges equals supply voltage and the advantage such as conduction impedance is more stable in input reference signal.Switch cut-off when control end adds low level.During analog switch conducting, conducting resistance is tens ohm; During analog switch cut-off, present very high impedance, can become open circuit.Analog switch can transmission of digital signals and analog signal, and the upper limiting frequency of the analog signal that can transmit is 40MHz.That analog switch has possessed is low in energy consumption, speed fast, machinery-free contact, volume is little and the advantage such as long service life.
4, in measure, its feature one is, adjustable at the frequency agile due to oscillating unit, completely can the such ideal situation of furnishing when producing, and at operation push-button in the needed time, (as 0.5 second), has completed the necessary condition of twice variation code.Its feature two is, because only need not two with a coding integrated circuit, and this integrated circuit chip select end ground connection, circuit is reliable.
5, except oscillating unit and fgs encoder peripheral element and element, formed radio frequency and produced and launch necessary part, radio-frequency transmissions pipe wherein and frequency modulation(FM) pipe are shared.
6, at oscillating unit, be welded with luminous indication, its object one is whether not only to find out the situation of circuit in opening, and the more important thing is that this measure is the special transmitting that adopts dicode, thereby when work shape, the indicator light being connected with oscillating unit, in flashing state, can find out that whether its operating conditions is correct fully aware ofly.
7,, in radio frequency, this patent one is to adopt induction-regulated circuit, reduces volume, the 2nd, and the generation of radio frequency adopts a pipe with modulation simultaneously, has increased like this reliability of circuit.Because triode belongs to consumable accessory.Above 2 points, have reduced whole space face simultaneously and have occupied situation.
8, in radio frequency, this patent adopts induction-regulated circuit, and its benefit is that induction regulation coil is little, and than fixedly crystal oscillator volume is little, its antenna adopts copper platinum in printed panel to apply into certain switch, and whole volume is little, can be contained in less launch-box.
Enforcement is rear or under the cooperation of the supporting receiver of designer, the present invention has following outstanding advantage to be:
1, greatly promoted the character of rudimentary coding integrated circuit, by common solid size transmitting, two yards of transmittings have been become, after receiving circuit cooperation by inventor, there is the very high anti-ability of cracking, because rudimentary coding integrated circuit has cheap advantage, so its product has very strong competitiveness.
If 2 with the coordinating of rolling code circuit, it decodes difficulty is superpower, because rolling code is the coding of a class character, and in this measure, dicode transmitting is the coding of a class character, two kinds of coded combinations of different nature, crack difficulty than a kind of coding of character larger.
3, become the more flexible of code, can be welded as 1 with the change code of X, also can be welded as 0 with the change code of X, increased level of confidentiality.
4, reliably, its reason is while launching the change code of dicode generation to the transmitting of the dicode of this measure, can be disorderly, only can repeat, and two kinds of change yard states are obvious, offer a clear explanation, and the receiving unit designing with inventor extremely mates.
5, less demanding to triode of commissure condenser type complementary type oscillating circuit, withstand voltage can being used in of triode requires high circuit, thereby adaptive surface is very wide, has expanded transmitting field.
6, electronic relay is bidirectional analog switch, has possessed that low in energy consumption, speed is fast, machinery-free contact, volume is little and the advantage such as long service life.
7, circuit is reliable, and the one, circuit is simplified, and the 2nd, easy failed part triode only has one, and the 3rd, after induction regulation coil envelope is filled with, inductance value is difficult for changing.Four, be that antenna is applied into by printed panel, do not produce variation in shape, do not affect radio frequency, adopted the elite of universal design.
8, produce easily, the one, equipment that need not be valuable and instrument, the 2nd, technology is simple, the 3rd, circuit simplify and element requirement used low, so can produce very high first-pass yield, very applicable minuscule-type-enterprise produces.
