This measure is explained as follows further:
A kind of double hose monostable radiating circuit is made up of jointly battery, emission switch, two-tube modified model monostable circuit, inverter, coding integrated circuit, radio circuit, it is a kind of form common coding with three kinds of states being upgraded to a kind of high code, while reaching dicode transmitting object, make reception possess the uniqueness of output, promote the level of confidentiality of remote control further.
Controlling to become in the circuit of code, two-tube modified model monostable circuit and inverter define to change and change the control circuit that code also conjugates end, for the address code of this adhesive integrated circuit have been classified two classes by this this measure, a class has been the fixed code welded, and a class is the vicissitudinous variation code of tool.Fixed code is a part of earth connection, and a part connects power supply, and variation code connects with individual output of two-tube modified model monostable circuit, when launching, original once transmitting has been become continuous print twice emitting.So first time substantially increases 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 can sound out closely by means of a kind of code reader (being the reflector sending different codings according to certain rules) and crack out password.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.
One, two-tube modified model monostable circuit is made up of front triode, rear triode, collector resistance, biasing resistance, commissure electric capacity, speed-up capacitor, differential capacitance, diac.Two-tube modified model monostable circuit 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, initial condition effect is obvious, strong interference immunity, and the logic theory of formation is fairly obvious, and active is few, only two, thus checks with convenient for production, and simple in circuits, not only reliability is high, and easily produces.
Two, the first variation code produces the output principle explanation of twice conversion:
1, line construction is that the monostable circuit formed by two pipes develops, and before on the basis of circuit, triode adds a resistance to earth, then adds differential circuits for triggering to this pipe emitter.When emission switch closes, differential circuit adds a high position to front transistor emitter, is equivalent to add negative pressure to forward bias, and this just determines front transistor collector voltage is high-order cut-off state, otherwise rear triode is saturation condition.Namely be the output of two-tube modified model monostable circuit be low level, the first state that Here it is, the first variation code of the coding integrated circuit connected with it is also in low level.
2, form the principle of twice conversion, initial condition is the first state, and the output of two-tube modified model monostable circuit is low level.At this moment the biasing resistance of front triode is to commissure capacitor charging, after the electricity of electric capacity is full of, now bias current will cause first three pole guarantee adequate food and, now will cause rear triode without bias current current collection very high-order, now become the second state, the first variation code of coding integrated circuit changes high-order state into by low level.
3, two-tube modified model monostable circuit simple in circuits, adjustability is high, adjustment biasing resistance and commissure electric capacity, adjustable launch time, convenient and reliable, and have well bulk, it is easy to produce.
Three, the reason of the second variation code transformation:
Second variation code is connected in the output of inverter, the input of inverter is the output being connected to two-tube modified model monostable circuit, therefore, when the output of two-tube modified model monostable circuit is the low level of the first state, due to the principle that inverter is anti-phase, therefore the output of inverter is high-order, so the second variation code connected with it is also thereupon for high-order, this is a subcategory number state of the second variation code, when high-order after the output of two-tube modified model monostable circuit changes, the now output of inverter is low level, so the second variation code connected with it also changes low level into by a high position, this is the code state after the second variation code changes.
Logical inversion is not only by inverter, also possessed the function of shaping, so be applicable to radiating circuit very much.
Four, after emission switch is pressed, two-tube modified model monostable circuit starts immediately, form twice conversion, form the conversion of inverter, two variation codes of control coding integrated circuit also form 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, the principle possessing unique output is received:
The data terminal of coding integrated circuit only has high-order just startup, and have two bits termination to conjugate end, be connected in the output of two-tube modified model monostable circuit and the output of inverter, therefore when the output of two-tube modified model monostable circuit is a high position, the the first displacement end connected with it is that a high position works, and inverter is because anti-phase is low level, so the second displacement end connected with it is that low level is inoperative, and work as the output low level of two-tube modified model monostable circuit, the the first displacement end connected with it is that low level is inoperative, and inverter is because anti-phase is high-order, so the second displacement end connected with it is that a high position works, this completes the transformation of displacement end, form the corresponding uniqueness receiving output, improve the level of confidentiality of coding further.
Six, in radio circuit, the utility model one adopts induction-regulated circuit, and its benefit is that induction regulation 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:
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, after the two-tube modified model monostable circuit of this measure 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, the displacement end while becoming code in data transfer end, forms the uniqueness receiving and export, improves the level of confidentiality of remote control further.
5, two-tube modified model monostable circuit is reliable, has initial condition, thus in twice conversion, has timing, therefore have outstanding performance, and this two dot characteristics is all very significant for raising level of confidentiality.In addition a spotlight of this circuit is, initial condition effect is obvious, strong interference immunity, and the logic theory of formation is fairly obvious, and active is few, only two, thus checks with convenient for production, and simple in circuits, not only reliability is high, and easily produces.
6, in radio circuit, the generation of radio frequency adopts a pipe with modulation simultaneously, which increases the reliability of circuit.After induction regulation 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.
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, four is that cost is low, and very applicable minuscule-type-enterprise produces.
