Measure summation
Radio coding technology is the key project of this business research, is also a kind of series of studies project.Why become series of studies; reason one is; apply very wide; it two is; from the angle of maintaining secrecy; existing coding techniques is a kind of research of direction; and the utility model is the research of other direction; thus can have better secret effect, it three is that the utility model is that the fixed code with tri-state state is upgraded to a kind of highly dense encoding state; because this coding has the change of a variety of form; and each version all has great importance, so propose the scheme of innovation, form series protection.And the emphasis of this measure uses a kind of monostable circuit of four not gate compositions to form transducer, control coding integrated circuit, thus such emission principle is defined: during each launching code, coding integrated circuit transmits twice coding, and twice coding has sequential, thus common regular coding is promoted in order to a kind of High Security Level is encoded.
This measure is explained as follows further:
One, to the explanation of transducer in this measure:
1, the principle that this measure is formed is, it is the variation code being connected coding integrated circuit by a kind of output of converter, thus such emission principle is defined: during each launching code, encoding integrated is transmit twice coding, and twice coding has sequential, thus common regular coding is promoted in order to a kind of High Security Level is encoded.In the technology in modern times, criminal heuristically can crack out password closely by means of a kind of code reader (being the reflector sending different codings according to certain rules).In rolling code, only managing its coding sent is change, and quantity is a lot, but because be first encoding when launching, so in theory still there is the probability cracked.And just can crack because reception that the present invention is corresponding must receive twice coding, so crack by the rule of first encoding, it cracks probability is obviously zero, to form the direction research of alternative High Security Level.
2, the converter in this measure, be constitute a kind of monostable circuit by four not gates and form, this converter monostable replaces, and mainly has two large benefits, and one is can realize the fixing unification of initial state, so can strengthen the timing of launching.The twice emitting principle producing this rule is, after emission switch is closed, the output of the first not gate is low level, because the commissure electric capacity between the first not gate and the second not gate can not transition, so the second not gate exports as high-order.4th not gate exports as high-order simultaneously.Become launch export initial state, now commissure electric capacity upper bias current to capacitor charging, now become cycle first stage.After electric capacity electricity is full of, now the second not gate be input as a high position, become the second stage of transmitting.3rd not gate and the 4th not gate have great significance, and have very strong shaping operation, and reason is in the change of two states, can accelerate the time of two phase change, make waveform more precipitous, thus have better launching effect.
Two, in measure 1, four non-gate-type monostable transducers define such annexation with coding integrated circuit, the address code 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 variation code that gate-type monostable transducer non-with four is connected.When manual operation is launched, four non-gate-type monostable transducers form conversion, it exports height conversion, and the movable code of coding integrated circuit just becomes 1 and 0 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.
Three, in measure 1, the value of adjustment integrating capacitor and integrating resistor, can adjust the time of its conversion, completely can the such ideal situation of furnishing when producing, within the time required for operation push-button, (as 0.5 second), completes the necessary condition of twice change code.And integrated circuit of encoding only has used one piece, this integrated circuit chip select end ground connection, circuit is reliable.
Four, except four non-gate-type monostable transducers and coding peripheral element and except element, constitute the necessary part that radio frequency produces and launches, wherein transmitting tube and modulating tube are shared, simple and convenient.
Five, in radio frequency, the utility model 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.Above 2 points, decrease overall face, space simultaneously and occupy situation.
Six, in radio frequency, the utility model 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 Foil in printed panel to apply into, and whole volume is little, can be contained in less launch-box.
Seven, the effect of indicating circuit is, can conclude whether reflector normally works with checking that whether indicator light is bright, conveniently reliable.
After implementing or under the cooperation of the supporting receiver of designer, the present invention has following outstanding advantage to be:
1, oscillating circuit is formed with coding integrated circuit and coordinates, and revolutionizes the fixed transmission form of common coding, and the regular coding of coding integrated circuit has been become movable oscillation form, reach the object of variation code, therefore, greatly improve the level of confidentiality of coding, there is the very high anti-ability of cracking.
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 four non-gate-type monostable transducers are reliable, and inversion frequency is adjustable, and two is that in radio circuit, 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 minuscule-type-enterprise produces.
