Description
Technical Field
The invention relates to the technical field of electronic cigarettes, in particular to a two-line authentication data communication circuit for an electronic cigarette.
Background
The electronic cigarette is an electronic product simulating cigarettes, can give people smoke, taste and feeling similar to actual smoking, can satisfy people with smoking habits, and can reduce the influence of harmful substances in the cigarettes on the body of smokers. At present, most electronic cigarettes in the market do not have the encryption authentication function, and certain electronic cigarettes with the encryption function adopt a storage chip arranged in an electronic cigarette cartridge and carry out encryption identification through a password in the storage chip. The smoking set and the cartridge of the existing electronic cigarette adopt a two-wire connection mode, and VCC and ground are connected with a heating wire on the cartridge. The resistance of the heating wire is about 1 ohm, and the heating wire can heat and atomize the tobacco tar. Due to the requirement of tobacco compliance and anti-counterfeiting requirement, an encryption chip needs to be added on the cigarette cartridge to authenticate the cigarette cartridge and record related parameters. In consideration of cost, a low-cost communication mode needs to be adopted between the cigarette rod and the cigarette cartridge.
The line which adopts a single data line for communication is called single-line communication, and at present, various single-line protocol standards exist. Such as the SWP standard established by ETSI (european telecommunications standards institute), which specifies the communication interface between the SIM card and the NFC chip. SWP (single wire protocol) is a method for implementing full duplex communication on a single wire. The direction of communication is UICC (universal integrated chip card) and CLF (contactless frontend). S1 is a voltage signal, the SIM card overvoltage meter detects the high and low levels of the S1 signal, and level width modulation is adopted; the S2 signal is a current signal and adopts a load modulation scheme. The S2 signal must be asserted when the S1 signal is high, turn on a transistor in the S1 signal when the S1 signal is high, and the S2 signal can be transmitted. The S1 signal and the S2 signal are superposed together to realize full duplex communication on a single wire. The ground Wire, the data Wire and the data Wire simultaneously supply power to the slave, and the host and the slave can be converted under certain conditions) single Bus (1-Wire Bus) technology is originally proposed by Dallas corporation. At host write time, there are two write slots in the single bus communication protocol: write 0 write 1. The master writes 1 to the slave using a write 1 slot and writes 0 to the slave using a write 0 slot. All write slots take at least 60us and a recovery time of at least 1us between two independent write slots. Both write slots start with the host pulling down the data bus. Manner of generating 1 slot: after the host pulls down the bus, the bus must be released within 15us, and the bus is pulled to high level by the pull-up resistor; the write 0 slot is generated in such a way that after the host pulls low, it only needs to stay low (at least 60us) for the whole slot. During 15-60 us after the beginning of the write time slot, the single-bus device samples the total level state. If the sampled value is high during this period, a logic 1 is written into the device; if 0, write logic 0. The solid black line in the figure represents the system host pulling the bus low, and the dashed black line represents the pull-up resistor pulling the bus high. The read timing is also similar, and the slave is replaced to perform the pull-down operation.
The single-wire protocol is mature, but the scheme cannot be directly applied to an electronic cigarette authentication circuit. Because the resistance of the heating wire is very small, about 1 ohm, the encryption chip is difficult to directly transmit data from the smoke bomb end because the resistance of the heating wire is too small. One possible scheme is that the encryption chip controls an MOS tube, and the heating wire is turned off during authentication. If the cost is increased by using an external MOS, and if a chip internal MOS is used, a large current path exists in the chip, which brings adverse effect on the stability of the chip.

The invention provides a two-line authentication data communication circuit for an electronic cigarette.
In an embodiment of the present invention, as shown in fig. 1-2, the two-line authentication data communication circuit for an electronic cigarette is composed of an electronic cigarette control chip 100 and a cigarette cartridge encryption chip 200, where the electronic cigarette control chip 100 is disposed at a cigarette end of the electronic cigarette, the cigarette cartridge encryption chip 200 is disposed at a cigarette end of the electronic cigarette, and the electronic cigarette control chip 100 is in communication connection with the cigarette cartridge encryption chip 200 for implementing data signal transmission between the cigarette end and the cigarette end of the electronic cigarette.
In this embodiment, the electronic cigarette control chip 100 includes: microcontroller and tobacco rod receiving circuit, wherein, microcontroller and tobacco rod receiving circuit are connected.
Specifically, after the smoke bomb encryption chip completes the security functions of key initialization, random number generation, data MAC generation, authentication reading and writing and the like, the encryption chip shapes and extracts the data signal after receiving the data signal transmitted by the microcontroller through the power line, and sends the shaped and extracted data signal to an encryption circuit on the encryption chip for encryption calculation and data reading to obtain a data signal stream to be sent. The electronic cigarette rod end transmits a data signal to the electronic cigarette bullet end, and the data signal is directly transmitted by adopting a single-wire protocol. When the electronic cigarette cartridge end transmits a data signal to the electronic cigarette cartridge end, the electronic cigarette cartridge end encryption chip generates a changed current signal on the transmitting coil to generate a space alternating electromagnetic field, the antenna at the cigarette rod receiving end induces a corresponding voltage signal, and the corresponding data signal can be decoded after the voltage signal is subjected to operations such as filtering, amplifying, shaping and judging. Thereby realize carrying out data signal interaction between electron cigarette bullet end and the electron cigarette rod end.
Specifically, the encryption chip performs manchester coding on a data signal stream to be transmitted to obtain a required current signal waveform, the current signal waveform is modulated by a waveform generation and operational amplification circuit in the encryption chip to obtain a current signal, and the current signal is amplified by a power amplifier and flows through a transmitting coil of the encryption chip, so that an alternating electromagnetic field is generated. It should be noted that heating loads such as heating wires are further arranged in the cigarette cartridge end of the electronic cigarette, the heating loads are connected with the power supply ends a and B, and when the cigarette cartridge encryption chip 200 and the cigarette rod control chip realize bidirectional authentication, the power supply ends a and B are conducted to enable the heating loads to start heating.
In this embodiment, the tobacco rod receiving circuit includes a comparison circuit, an amplification circuit, a low-pass filter circuit and a receiving module, and the receiving module, the comparison circuit, the amplification circuit and the low-pass filter circuit are in communication connection with the microcontroller.
In this embodiment, the alternating electromagnetic field is coupled to the receiving module to obtain a voltage signal.
In this embodiment, the receiving module filters the high-frequency voltage signal from the received voltage signal through a low-pass filter circuit. The amplifying circuit is used for amplifying the voltage signal with the high frequency filtered. The comparison circuit is used for carrying out threshold judgment on the amplified voltage signal, and obtaining a data signal given by the encryption chip after the voltage signal is subjected to low-pass filtering, amplification and threshold judgment. Because the magnetic permeability mu of the air is very small, the voltage signal sensed by the electronic cigarette rod is very weak. The voltage signal is low-pass filtered, amplified and threshold-judged to obtain the data signal from the enciphering chip. The circuit can be completed by discrete devices and simultaneously can be completed by an MCU with an integrated operational amplifier and an ADC with proper precision.
In the present embodiment, the frequencies adopted by the alternating electromagnetic field are 10K, 15K, 20K, 25K, 30K.
The data signal transmission process is as follows:
(1) the smoke cartridge encryption chip 200 performs manchester encoding on a data stream to be transmitted to obtain a required current signal waveform. The current signal waveform can be transmitted by a baseband or modulated by a high-frequency carrier wave, and the carrier frequency can be from 1M to 20M; when the high-frequency carrier is selected, 100% modulation or 10% modulation is selected, or baseband transmission can be directly used, and the rate adopts return-to-zero codes of 10K, 15K, 20K, 25K and 30K or Manchester coding. The communication mode has the advantages of proper transmission speed, stability, reliability, simple and mature circuit in the chip and low cost.
(2) The modulated current signal is amplified by a power amplifier in an amplifying circuit and flows through a transmitting coil, so that an alternating electromagnetic field is generated;
(3) the alternating electromagnetic field is coupled to a receiving module at the end of the cigarette rod, wherein the receiving module is a receiving antenna, the receiving antenna induces a voltage signal, the voltage signal received by the receiving antenna is filtered by a low-pass filter in a low-pass filter circuit to remove a signal with higher frequency, and the signal is amplified and decoded to obtain a data signal given by an encryption chip.
The data signal transmission coding and waveform design is as follows:
take 20K communication rate, round coil as the transmitting antenna of the cartridge as an example. The transmitting end current of the smoke cartridge end is I, the number of antenna turns is M, R is the circular radius of the antenna, and Y is the distance between the antenna and the center of the coil along the vertical direction of the antenna. In actual communication, and at 20K rate applications, the communication distance X is much smaller than the wavelength of the 20KHz alternating electromagnetic field, so the approximate formula for the magnetic field strength H at the firing end of the cartomizer:
the area of the coil at the receiving end of the cigarette rod is S, and because the area of the circuit board in the cigarette rod is very small and the number of turns is very large, the H values of all points when the cigarette rod passes through the receiving coil can be approximately considered to be the same. When the receiving end coil and the transmitting end coil of the tobacco rod are parallel, the value of the magnetic flux phi at the end of the tobacco rod is as follows:
Φ≈μHS (2)
when the number of turns of the cigarette rod coil is N, the induced voltage V induced on the receiving end antenna is as follows:
from the above formula, K is constant under the conditions that the positions of the cartridge and the tobacco rod are fixed and the area and the number of turns of the coil are fixed. Therefore, the induced voltage at the antenna end of the tobacco rod is in direct proportion to the differential of the current at the transmitting end of the smoke cartridge antenna.
When the signal of the receiving end of the cigarette receiving rod is a high-low level binary coding signal, the current waveform of the sending end is in an integral form corresponding to the induction voltage. Without loss of generality, as shown in fig. 3, when the current i of the antenna at the transmitting end of the cartridge is in the form of a triangular wave shown in fig. 3, the coil at the end of the cigarette rod generates an induced voltage corresponding to a manchester code stream. Through the communication mode, the data of the cigarette end can be transmitted to the cigarette rod end at the rate of 20 Kb/s.
Wherein, under the fixed condition of electron cigarette tobacco rod and cartridge, its communication distance is certain timing. At the moment, the number of turns of the transmitting coil, the area of the tobacco rod receiving end antenna, the number of turns of the tobacco rod receiving end antenna and the like can be adjusted according to the formula (3), so that the signal transmission effect reaches the optimal condition.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
