2, power valve is high-frequency tube.
3, integrated circuit is weaved into 2262.
4, the upper inclined diode of the first PNP triode is face fit type diode.
This measure is explained as follows further:
1, in this measure, the oscillating unit realizing becoming code is a very important part, and deviser devises interlock circuit and coordinates with it, in detail as shown in Figure 2.
The principle of vibration is: when the base stage of circuit debugging first PNP triode has a small amount of base current, its collector current becomes the larger base current of the 2nd NPN triode, at this moment the collector current that the 2nd NPN triode is larger, become again the base stage more big current of the first PNP triode, form very large feedback, two pipes are saturated rapidly.At this moment the emitter ground capacitance of the first PNP triode is connected to, rapidly by the 2nd NPN transistor collector electric discharge, when the voltage of electric capacity discharge and base voltage lower than the first PNP triode time, this pipe changes cut-off direction into by saturated immediately, and its collector current diminishes, and the base current of the 2nd NPN triode diminishes, its collector current diminishes, the base current affecting so again the first PNP triode conversely reduces, and produces and strongly end to two pipes the change in directions, until cut-off.Complete the period 1 of vibration.At this moment the ground capacitance connecing the first PNP triode emitter starts again charging, and when the base voltage of voltage higher than this pipe, this pipe is open-minded, produces the strong row positive feedback of two pipes, produces second round, and more cycle later.Upper on the high side Diode series of the first PNP triode in Fig. 2, mainly can control easily and adjust oscillation frequency.
2, in measure 1, oscillating unit defines 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 connected in advance, and another part is the change code be connected with oscillating unit.When manual operation is launched, oscillating unit vibrates, and the movable code of coding integrated circuit just becomes 0 and 1 two states, and integrated circuit of at this moment encoding just can only become dicode two kinds output by a kind of single code transmissions from former.By the excitation to modulator tube, reach the object of dicode modulate emission.
3, in measure 1, its feature one is, adjustable at the frequency agile due to oscillating unit, completely can the such ideal situation of furnishing when producing, and within the time required for operation push-button, (as 0.5 second), completes the necessary condition of twice change code.Its feature two is, need not two pieces because only using a block forecast integrated circuit, and this integrated circuit chip select end ground connection, circuit is reliable.
4, except oscillating unit and fgs encoder peripheral element and except element, constitute radio frequency and produce and launch necessary part, power valve is wherein shared with modulator tube, simple and convenient.
5, luminous instruction is welded with at oscillating unit, its object one not only to find out whether circuit is in situation about opening, and the more important thing is that this measure is the special transmitting adopting dicode, thus when working shape, the pilot lamp be connected with oscillating unit is in blinking state, can find out that whether its operating conditions is correct fully aware ofly.
6, in radio frequency, this patent one adopts induction-regulated circuit, reduces volume, and two is that the generation of radio frequency adopts a pipe with modulation simultaneously, which increases the reliability of circuit.Because triode belongs to consumable accessory, above 2 points, decrease overall face, space simultaneously and occupy 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.
After implementing or under the cooperation of the supporting receiver of deviser, the present invention has following outstanding advantage to be:
1, the character of rudimentary coding integrated circuit is greatly improved, two yards of transmittings are become by common single code transmissions, after being coordinated by the receiving circuit of inventor, 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 are larger than a kind of code breaks difficulty of character.
3, the dicode of this measure is launched reliable, when its reason is the change code of transmitting dicode generation, can not be disorderly, and only can repeat, two kinds become code state obviously, and offer a clear explanation, the receiving unit designed with inventor extremely mates.
4, circuit is reliable, and one is that circuit is simplified, and two is that easy failed part triode only has one, and three is that after induction regulation coil envelope is filled with, inductance value not easily changes.Four, be that antenna is applied into by printed panel, do not produce change in shape, do not affect radio frequency, have employed the elite of universal design.
5, produce easily, one be need not be valuable equipment and instrument, two is that technology is simple, and three are that circuit is simplified and component requirements used is low, so can produce very high first-pass yield, very applicable microbusiness produces.
