This measure is further explained as follows:
1, in this measure, two NPN triode type oscillatory circuits of realizing change code are very important parts, and deviser has designed interlock circuit and coordinated with it, and adaptive surface is very wide, expands transmitting field.
This oscillatory circuit is to be mutually connected commissure electric capacity in base stage at the corresponding levels with the other side's collector with two NPN triodes to form.The principle that forms vibration is: when opening after power supply, in the time that a certain pipe collector is a high position, charge to the other side's base stage by commissure electric capacity, make square tube base stage obtain larger base flow, thereby accelerate to change to saturated trend, the logical collector voltage of triode that simultaneously saturated trend changes reduces, transmit the signal of saturated feedback low level to the other side's triode by commissure electric capacity, strong positive feedback impels the blanking tube originally changing to cut-off direction again to tend to cut-off, blanking tube makes saturated pipe more saturated by commissure electric capacity conversely, strong positive feedback completes the front half period of vibration for the first time, after commissure capacitor charging, former saturated pipe will change to exit axis, thereby the commissure electric capacity of two pipes transmits saturated and pick-off signal again, form before the semiperiod identical feedback change procedure, just the state variation of two pipes is different from the front semiperiod, the saturated pipe of front semiperiod transfers cut-off to, blanking tube becomes saturated, so principle produces the cycle for the second time, cycle for the third time------etc.
In foregoing circuit simple in circuits, less demanding to triode, is easy to be adjusted into the desired frequency of the person of establishing, and mates with whole circuit.Be a kind of outstanding circuit, another feature that another two features one of this circuit are this circuit is that the withstand voltage height of triode can be used in and requires high circuit, thereby adaptive surface is very wide, has expanded transmitting field.The 2nd, can become two output terminals.
2, in measure 1, two NPN triode type oscillatory circuits have formed such annexation with coding integrated circuit, the coded portion of coding integrated circuit has been divided into two parts, a part is the fixed code having connected in advance, this fixed code can ground connection, also can connect power supply, flexible and changeable, another part is the variation code being connected with two NPN triode type oscillatory circuits.In the time that manual operation is launched, two NPN triode type oscillatory circuit vibrations, the change code end 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 modulator tube, reach the object of dicode modulate emission.
3, because the frequency agile of two NPN triode type oscillatory circuits is adjustable, completely can the such ideal situation of furnishing in the time producing, within the needed time of operation push-button, (as 0.5 second), has completed the necessary condition of twice variation code.Because only need not two with a coding integrated circuit, coding integrated circuit chip select end ground connection, circuit is reliable.
4, except two NPN triode type oscillatory circuits and fgs encoder peripheral element and element, formed radio frequency and produced and launch necessary part, power valve wherein and modulator tube are shared, simple and convenient.

6,, 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 overall space face simultaneously and have occupied situation.
7, in radio frequency, this patent adopts induction-regulated circuit, and its benefit is that induction regulation coil is little, less than fixing crystal oscillator volume, and 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 deviser, the present invention has following outstanding advantage to be:
1, greatly promoted the character of rudimentary coding integrated circuit, two yards of transmittings are become by common solid size transmitting, after coordinating by inventor's receiving circuit, there is the very high anti-ability of cracking, because rudimentary coding integrated circuit has cheap advantage, so its product has very strong competitive power.
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, 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.
4, 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
5, oscillator circuit is succinct, and easily, with whole Circuit Matching, this circuit can become two output terminals, adapts to widely, has expanded transmitting field.
