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, adopt the complementary type circuit that two pipes are formed, coordinate differential circuit, constitute twice translation circuit of the variation code in a kind of control coding integrated circuit address code, common coded excitation is formed and becomes code transmitting.After twice translation circuit formed matches with integrated circuit, its feature one is when being used alone, the anti-ability of cracking that also tool is very high, when two is when it and rolling code combinationally uses, can play the optimum efficiency of combination among the strong ones.Three is have lower cost, is specially adapted to minuscule-type-enterprise.After enforcement, the change code common tri-state coded excitation being promoted to a kind of High Security Level is launched, and provides wide space for studying atypical transmitting.
This measure is explained as follows further:
One, differential expression complementary type reflector by battery, emission switch, differential complementary type twice translation circuit, coding integrated circuit, radio circuit forms jointly, is a kind of form common coding with three kinds of states being upgraded to a kind of high code.
The address code of coding integrated circuit have been classified two classes by this measure, and a class is the fixed code welded, and a class is the vicissitudinous variation code of tool.The connected mode one of fixed code connects power supply, and mode two is that a part connects power supply, and a part suspends.The output of variation code and differential complementary type twice translation circuit connects, and when launching, original once transmitting has been become continuous print twice emitting.So substantially increase level of confidentiality.If there is timing in addition, then on this, again can improve level of confidentiality.Its reason is, 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, differential complementary type twice translation circuit is made up of differential circuit, complementary circuit.Differential circuit is made up of differential capacitance, discharge resistance, trigger resistance.Complementary circuit is made up of prime NPN triode, rear class PNP triode, output earth resistance.Due to the complementarity of two pipes, so the circuit formed has very large multiplication factor, thus having good performance one is to carry out twice conversion, two is have initial condition, thus in twice conversion, have timing, the logic theory of formation is fairly obvious, thus meets designing requirement completely.In addition the bright spot three of this circuit is, this circuit power saving, and this is very important a kind of performance for radiating circuit.Bright spot four is simple in circuits, and peripheral element is little, and therefore not only reliability is high, and easily produces.
Three, the principle forming twice conversion is, when the closed connection of emission switch, the input differential circuit of prime NPN triode has very large electric current, flow into base stage and become base flow, prime NPN triode can produce a very strong current channel over the ground, and this passage just in time becomes the base flow passage of rear class PNP triode.Thus cause rear class PNP triode to enter saturation condition by amplification, become the first state high-order, namely the output of differential complementary type twice translation circuit is high-order.When capacitor charging is complete, prime NPN triode and rear class PNP triode will lose base flow simultaneously, so become cut-off shape, at this moment the output of differential complementary type twice translation circuit is low level, because the multiplication factor of two triodes is very large, so integrating capacitor can be used very little, this is a very important advantage for radiating circuit.Its outer second bright spot is that prime is served as by NPN triode, after rear class is served as by PNP triode, due to the complementarity of two triodes, so the circuit formed has very large multiplication factor, thus have good performance, one is to carry out twice conversion, and two is have initial condition, thus in twice conversion, there is timing, further increase level of confidentiality.In addition the bright spot three of this circuit is, this circuit power saving, and this is very important a kind of performance for radiating circuit.Bright spot four is simple in circuits, and peripheral element is little, and therefore not only reliability is high, and easily produces.
Four, after emission switch is pressed, differential complementary type twice translation circuit starts immediately, form twice conversion, the variation code of control coding integrated circuit also forms the conversion of twice thereupon, 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 of transmitting tube in radio frequency circuit, reach the object of dicode modulate emission.
Five, differential complementary type twice translation circuit simple in circuits, adjustability is high, adjustment integrating resistor and integrating capacitor and adjustable launch time, conveniently reliable, have well bulk, produce easily, differential capacitance adopts electrodeless electric capacity, reduce the electric leakage of electric capacity, allow each time of launching based on unanimously.
Six, in radio circuit, the utility model one adopts induction-regulated circuit, and its benefit is that frequency modulation coil is little, less than fixing crystal oscillator volume, and two is that the generation of radio frequency adopts a pipe with modulation simultaneously, which increases the reliability of circuit.Three is that its antenna adopts Copper Foil in printed panel to apply into, and whole volume is little, can be contained in less launch-box.Above 3 points, decrease overall face, space simultaneously and occupy situation.
After implementing or under the cooperation of the supporting receiver of designer, the present invention has following outstanding advantage to be:
After this measure is implemented, have powerful vitality, its reason is three important indicators for lift-off technology, and one is the distance of launching, and two is the levels of confidentiality of encoding, and three is that price situation has major improvement.Coding integrated circuit has wide purposes, little of toys, and large to senior security personnel, the fields such as communication all extremely need, and thus purposes is very extensive.Be mainly manifested in:
1, revolutionize the fixed transmission form of common coding, the regular coding of coding integrated circuit has been become movable variation, 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.
2, after differential complementary type twice translation circuit coordinates with coding integrated circuit, when being used alone, higher level of confidentiality can be had, after coordinating with rolling code, can realize 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, differential complementary type twice translation circuit is reliable, two triodes have complementarity, so the circuit formed has very large multiplication factor, thus having good performance one is to carry out twice conversion, two is have initial condition, thus in twice conversion, have timing, the logic theory of formation is fairly obvious, thus meets designing requirement completely.Three are, this circuit power saving, and this is very important a kind of performance for radiating circuit.Four is simple in circuits, and peripheral element is little, and therefore not only reliability is high, and easily produces.
5, in radio circuit, the generation of radio frequency adopts a pipe with modulation simultaneously, which increases the reliability of circuit.After frequency modulation coil envelope is filled with, inductance value not easily changes.Copper foil antenna antenna is applied into by printed panel, does not produce change in shape, does not affect radio frequency, have employed the elite of universal design, can be contained in less launch-box, decreases overall face, space and occupies situation.
6, 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.
