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 is a kind of form common coding with three kinds of states being upgraded to a kind of high code, that employing two Guan Yuqi often close by the collector resistance of pipe, the mutual lotus root of biasing resistance, form a kind of bistable pressure state circuit not having contravention, form twice conversion, the bilateral analog switch that cooperation speed is fast, low in energy consumption, variation code in control coding integrated circuit address code, form variation code 0 to launch with the conversion suspended, in twice conversion, there is timing, therefore have outstanding performance, this two dot characteristics is all very significant for raising level of confidentiality.In addition a spotlight of this circuit is, the symmetry of two pipes is strong, and the logic theory of formation is simple, and its logical action is fairly obvious, thus checks with convenient for production, and simple in circuits, not only reliability is high, and easily produces.After enforcement, becoming a kind of novel High Security Level coding integrated circuit, providing wide space for studying atypical transmitting.
This measure is explained as follows further:
One, the principle that this measure is formed is, adopt the collector resistance of the every pipe of two Guan Yuqi, biasing resistance closes by mutual lotus root, form a kind of bistable pressure state circuit not having contravention, form twice conversion, cooperation speed is fast, bilateral analog switch low in energy consumption, variation code in control coding integrated circuit address code, form variation code 0 to launch with the conversion suspended, 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.So this research is very meaningful.
Two, the converter in this measure, constitutes a kind of steady-state circuit by two triodes and adds that a kind of translation circuit forms.Feature one after composition to carry out twice conversion, and two is have initial condition, thus in twice conversion, has timing, therefore has outstanding performance, and this two dot characteristics is all very significant for raising level of confidentiality.In addition a spotlight of this circuit is, the symmetry of two triodes is strong, and the logic theory of formation is simple, and its logical action is fairly obvious, thus checks with convenient for production, and simple in circuits, not only reliability is high, and easily produces.
Three, the output principle producing twice conversion illustrates:
1, line construction is closed by this pipe collector resistance of every Guan Yuqi, the mutual lotus root of biasing resistance, and form.This circuit is a bistable circuit typically not having contravention.Wherein the base stage direct-to-ground capacitance of second triode forms initial alignment electric capacity.Remaining part constitutes the circuits for triggering of another kind of state.
2, when control switch is just closed, the base stage direct-to-ground capacitance of second triode forms initial alignment electric capacity to be existed, so in risky motive, first triode is low level, second transistor collector must be high-order, become the first state of output, now the control end of bilateral analog switch is high-order, therefore bilateral analog switch is connected, its input and output short circuit, the input due to bilateral analog switch is earth connection, therefore, the output of bilateral analog switch is also low level, and the variation code connected with it is also low level 0 state.
When the output of two-pipe two-state control circuit is high-order, at this moment second triode through integrating resistor to integration capacitor charging, after capacitive charge value exceedes the door that diac formed, trigger second transistor base, now second triode becomes saturated, thus export the second state, now the control end of bilateral analog switch causes bilateral analog switch to disconnect because of dead electricity, so the output of bilateral analog switch now becomes both access failure power supplys, also the suspended state of access failure ground wire, the variation code connected with it is the suspended state by low level 0 state-transition also, this completes variation code 0 and the transformation suspended.
Four, the bilateral analog switch used 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 possesses the advantages such as low in energy consumption, speed fast, mechanical contact, is very suitable in radiating circuit.
Five, in measure 4, a controlling resistance is used to replace bilateral analog switch with control triode, such benefit is, all in whole circuit, except coding integrated circuit, all elements are all separation members, and this control triode is the same with two triodes in two-pipe two-state control circuit, it is all NPN triode, element not be used in be looked in addition, a controlling resistance is used to replace the form of bilateral analog switch with control triode, the result that variation code obtains is the same with bilateral analog switch, it is all the coded signal that 0 change suspends, because when the output of two-pipe two-state control circuit is high-order, the base stage controlling triode has voltage to exist, cause controlling triode saturated, thus its current collection very low level, 0 state, the variation code connected with it is also low level 0 state.When the output of two-pipe two-state control circuit is low level, control the base stage dead electricity of triode, control triode is made to change cut-off into from saturated, its collector electrode changes the suspension in both unearthed lines also missed electric source into by low level, and the variation code connected with it is also suspended state by low level 0 state-transition.
Be no matter the circuit that bilateral analog switch or a controlling resistance and control triode, integrated circuit of can encoding can only become dicode two kinds output by a kind of single code transmissions from former.By the excitation of transmitting tube in radio frequency circuit, reach the object of dicode modulate emission.
After implementing or under the cooperation of the supporting receiver of designer, the present invention has following outstanding advantage to be:
1, revolutionize the fixed transmission form of common coding, the regular coding of coding integrated circuit has been become movable oscillation form, has reached the object of variation code, therefore, greatly improve the level of confidentiality of coding, there is the very high anti-ability of cracking.
When 2, being used alone, there is higher level of confidentiality, when coordinating with rolling code, achieve superpower combination, 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, dicode is launched reliably, when its reason is the change code launching dicode generation, can not be disorderly, and two kinds become code state obviously, and offer a clear explanation, the receiving unit designed with inventor extremely mates.
4, circuit is reliable, and the symmetry of two triodes is strong, and the logic theory of formation is simple, and its logical action is fairly obvious, thus checks with convenient for production, and simple in circuits, reliability is high.
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, four is that cost is low, and very applicable minuscule-type-enterprise produces.
