This measure is explained as follows further:
1, in this measure, the mapping mode of a kind of yard is first defined.Designer devises interlock circuit and coordinates with it, and this oscillating circuit is mutually connected commissure electric capacity in base stage at the corresponding levels with the collector electrode of the other side with two NPN triodes to form.The principle forming vibration is: after opening power supply, when a certain pipe collector is high-order, charged to the other side's base stage by commissure electric capacity, make to obtain larger base flow to square tube base stage, thus change is accelerated to saturated trend, the triode of saturated Long-term change trend leads to collector voltage reduction simultaneously, transmitted 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 changed 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 first time vibration, after commissure capacitor charging, former saturated pipe will change to exit axis, thus the commissure electric capacity of two pipes transmits saturated and pick-off signal again, formed before the half period identical feedback change procedure, just the state variation of two pipes is different from the front half period, the saturated pipe of front half period transfers cut-off to, blanking tube becomes saturated, principle like this produces the second time cycle, cycle third time------etc.
In foregoing circuit simple in circuits, less demanding to triode, is easy to the frequency be adjusted to required by the person of establishing, and mates with whole circuit.Be a kind of outstanding circuit, the feature of this circuit is that the withstand voltage height of triode can be used in and requires high circuit, and thus adaptive surface is very wide, has expanded transmitting field.
2, in measure, two NPN triode type oscillating circuit defines such annexation with coding integrated circuit, 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 two NPN triode type oscillating circuit.When manual operation is launched, two NPN triode type oscillating circuit vibration, 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 modulating tube, reach the object of dicode modulate emission.

Illustrate with the first block forecast integrated circuit: two outputs of two NPN triode type oscillating circuit are one high and one low circulations, if first piece of control end weaving into first bilateral analog switch that integrated circuit is joined is for time high-order, if the input of first bilateral analog switch is earth connection, when control end is high-order, first bilateral analog switch is connected, therefore the output i.e. change code end of the first block forecast integrated circuit can obtain low level, be 0, when the control end that first piece is weaved into first bilateral analog switch that integrated circuit is joined is low level, first bilateral analog switch disconnects, now the change code end of the 5th block forecast integrated circuit obtains will being suspend, be X, thus realize be 0 with the cyclical-transformation of X.In like manner, 1 be also easy to obtain with the cyclical-transformation of X.
The output of two block forecast integrated circuits is used or gate diode isolation, has therefore shared a modulated resistance, simple and reliable.
4, the bilateral analog switch in Fig. 1 is CD4066, and when control end adds high level, switch conduction, conduction impedance is lower, and in addition, conduction impedance is substantially constant in whole input reference signal.Eliminate the change of switching transistor threshold voltage with input signal, therefore within the scope of whole working signal, conduction impedance is lower.Compared with single channel switch, there is input signal peak voltage ranges and equal supply voltage and the advantage such as conduction impedance is more stable in input reference signal.The 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 open circuit be become.Analog switch can transmission of digital signals and analog signal, and the upper limiting frequency of the analog signal that can transmit is 40MHz.Analog switch possess low in energy consumption, speed fast, mechanical contact, volume are little and the advantage such as long service life.
5, the frequency agile due to two NPN triode type oscillating circuit is adjustable, 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.
6, transmit easily disturb by other remote control product, therefore two block forecast integrated circuits are selected, greatly reduce the impact of other remote control product, launching is no longer single code bit, therefore the accuracy of transmitting is greatly improved, and specific a kind of copper foil antenna of English lower case n shape, the better coupling that allowed launching and receiving have.
7, in radiating circuit, adopt crystal oscillator type circuit, its benefit is that radio frequency is stablized, and characteristic is good, so may be used for the place needing remote control distance far away.
After implementing or under the cooperation of the supporting receiver of designer, following outstanding advantage is had to be:
1, used two block forecast integrated circuits, all possess and become code ability, secrecy promotes greatly, achieves the change code form of the coding integrated circuit of low price, improves the character of coding integrated circuit, improves especially and prevents cracking ability.
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, become the more flexible of code, the change code of 0 and X can be welded as, also can be welded as the change code of 1 and X, add level of confidentiality.
4, 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.
5, two NPN triode type oscillating circuit, starting of oscillation is easy, and triode is indefectible element, and therefore circuit is reliable and stable, and debugging is simple, easily with the integrated Circuit Matching of coding, has expanded transmitting field, can have two outputs, widely applicable.
6, the bilateral analog switch used possess low in energy consumption, speed fast, mechanical contact, volume are little and the advantage such as long service life.
7, 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 minuscule-type-enterprise produces.
8, transmitting sensitivity is improved, the better coupling that allowed launching and receiving have.
9, adopt crystal oscillator type circuit, radio frequency is stablized, and characteristic is good, is applicable to the place needing remote control distance far away, adds the distance of transmitting.
