Embodiment
As shown in Figure 1, the present invention is grouped into by being contained in signal transmission unit branch in the battery and the signal processing part that is contained in the portable terminal, and signal transmission unit divides to signal processing transmission identification code ID, and its send mode adopts serial data mode and simplex mode; Signal processing receives the identification code ID that divides from signal transmission unit, and this information is decrypted, verifies, thereby judges the true and false of battery.In order to prevent that data from producing the error code identification that makes the mistake in transmission course, identification code will be sent repeatedly continuously, and at this several times in the process of transmitting, as long as the data treated correct result that draws that do not make mistakes once, system just thinks and discerns successfully.In order to guarantee that signal sends and handles two parts and is operated in same frequency, signal processing is sent to signal transmission branch to the required clock of clock division acquisition identifying of portable terminal.
As shown in Figure 2, the signal transmission unit branch is designed to the ID sign indicating number of storage battery, and when detecting mobile terminal-opening, the scrambling of ID sign indicating number, modulation are sent to signal processing, the check of realization identity, it mainly is made up of ROM memory, data scrambler, signal modulator, discharge detecting, signal transmit control device, clock shaping, counter, the operating state of above-mentioned each module of signal transmit control device control, for example counter reset, the output of ROM memory data, signal modulator output selection etc.; In addition, when battery inserted load, the signal transmit control device received that the signal of the output of circuit for detecting starts working.The data of preserving in the ROM memory comprise three parts: the coding of synchronous head, battery production information and production information.Signal processing need be known from when beginning to carry out the identification to signal, begin data processing so need send specific synchronous head signal notification data processing section before the ID that sends battery.The production information of battery can comprise place of production, date of manufacture, sequence number of battery etc., and is as shown in table 1.The coding of production information is the result who production information is carried out computing by certain operation law, principle is: after the computing through the arithmetic element of signal processing of different true forms and its coding, that obtain should be the unified result of precognition, could judge the true and false of battery like this according to the one-side information of battery.Coded system is as follows:
Suppose the two section binary data ABs of the production information of battery for each 4bit, predetermined result is two sections binary data EF of each 4bit, and the coding of that production information also is two sections binary data CD of each 4bit.Wherein
Table 1
| The 8BIT synchronous head | Product information | The product IDs sign indicating number |
From the communication angle, before data are sent, to carry out the data scrambler and help to reduce the probability that error code appears in the data transmission, under different initial conditions, carry out scrambler simultaneously, make the data of each transmission all different, can play certain privacy functions.As shown in Figure 3, data scrambler mainly is made up of nine d type flip flops and a selector, adopts nine triggers that following some reason is arranged: the output of symmetry before and after the even number register may produce, reduce confidentiality; With reference to the principle of M sequencer, nine registers are as long as road feedback behind the 5th register just can produce the sequence of maximum cycle.It may be noted that after identifying begins as long as having under the situation of clock, scrambler is always in work and not zero clearing has different initial conditions when having guaranteed like this to use it at every turn.After synchronous head signal sends, begin to export the scrambler result.So that descrambler is carried out initialization, to nine ' 0 ' of scrambler inputs, the ID sign indicating number of battery is imported in the scrambler then earlier in order to preserve the scrambler initial value.
As shown in Figure 4, signal modulator is made of multiplexer MUX21, operational amplifier A 1, and its effect is the driving force that strengthens digital signal.Under the control of signal transmit control device, the data that MUX21 selects to connect from scrambler output are still exported synchronous head, and the voltage follower that operational amplifier A 1 is formed adds the driving force of large-signal.
As shown in Figure 5; the discharge circuit for detecting is made up of comparator C 1; its effect is when battery inserts load and electric current output is arranged; the VM pin voltage of battery protecting circuit raises; and with power supply VSS magnitude of voltage relatively; when VM voltage was greater than VSS when battery begins to discharge, discharge detector output high level produced commencing signal START notification signal transmit control device and starts working.
The clock shaping realizes with BUFFER.
The current state that should locate of each module of counter controls, counter comprises two parts: expression data send the counter STATE of number of times, a counter STEP who represents module job step in each process of transmitting.Data send once, and STAE adds one; Stop when reaching predetermined value sending.Each clock cycle of STEP adds one.
As shown in Figure 6; the workflow that signal transmission unit divides is: when mobile terminal-opening (battery begins discharge); the voltage that the discharge examination module detects battery protecting circuit VM pin is higher than supply voltage VSS and produces high level, the signal transmit control device is started working, reset counter.Behind system stability, data are sent to terminal after scrambling, modulation.Data whenever send once, and the counter STATE that the expression data send number of times adds one.After the value of counter reached a predetermined value, the expression data had sent repeatedly, and the signal transmission unit sub-controller quits work, otherwise data will be continued to send, and are false shutdown automatically, VM level step-down if portable terminal is judged battery, equal VSS, signal sending circuit also will quit work.
After waiting for end, signal modulator sends synchronizing signal to signal processing under the control of signal transmit control device; Subsequently, the ID sign indicating number of battery is imported in the scrambler, exports nine values of last trigger of scrambler simultaneously, exports the scrambler result then.
In addition, the stand-by period is greater than signal processing and finishes Data Receiving, a computing and make the required time of judging.Because when signal processing is missed real synchronous head and when detecting pseudo-synchronous head, result of determination is wrong beyond doubt.If data be send continuously or spacing distance less-than operation, judgement time, reciever judges to misdata and finishes when preparing to receive next time that real synchronous head has also missed, and will can not get correct data forever like this.
As shown in Figure 7, signal processing is designed to synchronous head that the received signal sending part divide to send, initial code, scrambler data and it is handled, and the information that therefrom draws is judged the true and false of battery.If battery is a counterfeit, the shutdown programm of start signal output portable terminal, it comprises: demodulator of PM signal PM, data de-scrambling device, arithmetic element, judgement unit, signal processing controller, clock division sum counter are formed as a result, signal processing controller links to each other with each module, be used to carry out State Control, during mobile terminal-opening, signal processing controller is started working, after demodulator of PM signal PM detects synchronous head, the operating state that control data descrambler, computing, result judge; Simultaneously, the output of signal processing controller reception result judge module behind each end of identification is if high level, identification will stop: if low level, identification will continue, up to surpassing preset time, think that identification is unsuccessful this moment, send signal enabling portable terminal shutdown programm.
Demodulator of PM signal PM will identify and be used to coordinate that signal transmission unit divides and the synchronizing signal of signal processing, signal processing controller is known when begin processing and identification to data.As shown in Figure 8, signal amplifies back serial input synchronization detecting section through shaping, the synchronous head of storing in the serial/parallel conversion back of 8BIT and ROM memory compares, if unanimity is sent confirmation of synchronization signalisation signal processing controller signal is outputed to the data de-scrambling device.
The data de-scrambling device will carry out computing to the identification code of receiving, must be earlier the data after the scrambling correct separate out, under signal processing controller control, the data de-scrambling device is finished this function.As shown in Figure 9, data de-scrambling device and data scrambler are basic identical, and after receiving synchronizing signal, descrambler is cleared, and accept nine data, make like this to add, have during descrambling identical initial condition; After initial value reads in, with result's output of descrambling.
Arithmetic element is that the coding to the production information of battery and this information carries out computing, and the result who draws is used for identity verification.As shown in figure 10, U1, U2 are the serial/parallel transducers of 8BIT, ENR reads in permission, ENS is that output allows, U3-U6 is the 4bit half adder, for identity is verified, operation result must be known and unified, and this just requires the result that different battery identification sign indicating numbers carry out obtaining after the computing should be a unified value.In this arithmetic element, follow the identification code result of calculation that can both obtain predicting, unified that coded system above-mentioned produces.
Judgement unit is that operation result is compared with the correct result who is kept among the ROM as a result, if the consistent high level of exporting of result, if inconsistent output low level, as shown in figure 11, that preserve in the ROM memory is battery production information and the correct result of coding after computing thereof, with the parallel true and false of relatively judging battery of operation result, if the result is correct, the output high level.
Clock division circuits carries out frequency division to the clock of portable terminal, obtains the required clock of identifying.
The current state that should locate of each above-mentioned module of counter controls, it comprises two parts: the counter STATE of comparative result number of times is read in an expression, a counter STEP who represents module job step in each data handling procedure.Whenever read comparative result one time, STATE adds one; If also there is not correct result when reaching predetermined value, portable terminal will be closed.Each clock cycle of STEP adds one.
As shown in figure 12, the flow process of signal processing is as follows: when mobile terminal-opening, signal processing controller is started working, data after amplify this moment are input to sync detection circuit, after demodulator of PM signal PM identified synchronous head, signal processing controller was imported the data de-scrambling device with signal and is carried out descrambling, then the data behind the descrambling was carried out computing and whether judged result is correct, if the result is correct, identifying finishes; If the result is incorrect, at first check whether operation of data has been reached pre-determined number, if do not have, identification is proceeded, otherwise battery is considered to fake products and starts the shutdown programm of portable terminal.
