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 integrating capacitor, constitute a kind of circuit possessing twice conversion, startup PNP triode control circuit carrys out the variation code in control coding integrated circuit address code, common coded excitation is formed and becomes code transmitting, twice translation 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, there is timing, the logic theory formed is fairly obvious, thus designing requirement is met completely.In addition the bright spot three of this circuit is, 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.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, a kind of complementary type radiating circuit by battery, emission switch, complementary type twice change-over circuit, PNP triode control 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 is a part of earth connection, and a part suspends, and mode two is whole earth connections.Variation code connects with the output of, PNP triode control circuit, 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, complementary type twice change-over circuit, be that a kind of PNP triode is served as by prime triode, rear class triode is served as by NPN pole pipe, 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 integrating resistor (being namely the base flow of prime triode) that prime transistor base connects charges to direct-to-ground capacitance, at this moment emitter is by radio stream powerful for generation one, and this electric current is the base flow of rear class triode, saturation condition is become so again amplify through rear class triode, become the first state, namely be the output of complementary type twice change-over circuit be low level, in this state, PNP in PNP triode control circuit controls the base stage of triode by base stage controlling resistance, produce bias current, therefore PNP is caused to control triode saturated, its current collection is very high-order, the output of PNP triode control circuit is high-order, the variation code of the coding integrated circuit connected with it is also high-end trim, this is the first state of variation code,
When capacitor charging is complete, prime triode and rear class triode will lose base flow simultaneously, so become cut-off shape, at this moment the output of complementary type twice change-over circuit is high-order, in this state, the bias current that PNP in PNP triode control circuit controls triode disappears, PNP is caused to control triode cut-off, the suspended state of its current collection very both access failure power supply also access failure ground wire, the output of PNP triode control circuit is suspended state, the variation code of the coding integrated circuit connected with it is also suspended state, and this is the code state after variation code changes.
Because the multiplication factor of two pipes is very large, so integrating capacitor can be used very little, this is a very important advantage for radiating circuit.
Four, after emission switch is pressed, complementary type twice change-over circuit starts immediately, form twice conversion, start the conversion that variation code that PNP triode control circuit carrys out control coding integrated circuit also forms twice thereupon, 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 modulating tube in radio frequency circuit, reach the object of dicode modulate emission.
Five, complementary type twice change-over circuit simple in circuits, adjustability is high, adjustment integrating resistor and integrating capacitor and adjustable launch time, convenient and reliable, and have well bulk, it is easy to produce.The meaning of its discharge diode is that integrating capacitor is discharged by discharge diode when emission switch disconnects, and prepares for next time launches.
The distance of six, launching and extraneous factor have very large relation, as the environment with surrounding, all have very large relation with weather.Particularly weather, under same extraneous circumstance, the launch and accept common when weather is good all often can reach tens meters, but when bad weather, its distance can be reduced to only several meters suddenly.For this reason, this measure have employed a kind of copper foil antenna of English lower case n shape, article two, connect with arc Copper Foil kissing above vertical Copper Foil, the Copper Foil width of copper foil antenna is 2 millimeters, the length of two the vertical Copper Foils in left and right is 30 millimeters, article two, the spacing of vertical Copper Foil is 20 millimeters, and the height that kiss connects the arc Copper Foil of two vertical Copper Foils is 4.5 millimeters.Strict formulation, the better coupling that allowed launching and receiving have, experiment proves, such being transmitted in decreases weather and surrounding environment to a great extent on the impact transmitted, and improves the intensity of transmitting.
Radio frequency adopts crystal oscillator type circuit, and 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, 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.
2, the coding integrated circuit of this measure, 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, complementary type twice change-over 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, have employed the copper foil antenna of ∩ shape, reduce extraneous bad weather and surrounding environment to the impact transmitted, improve emissive porwer.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.
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.
