Description

Consumable chip, printing consumable, packaging material, equipment and communication method

Technical Field

The application relates to the technical field of electronics, in particular to a consumable chip, a printing consumable, a packaging material, equipment and a communication method.

Background

The printing apparatus usually needs to configure corresponding printing consumables during the printing process. For example, an ink jet printer requires an ink cartridge containing ink therein; a powder cylinder is required to be configured in the laser printer, and carbon powder is contained in the powder cylinder; the multifunctional all-in-one machine needs to be provided with a toner cartridge, and carbon powder is contained in the toner cartridge. The printing supplies have a shorter life than the printing apparatus, and thus require the user to purchase and replace the printing supplies frequently during use.

In order to record the use of a printing supply installed in a printing apparatus and to perform identification and authentication of the printing supply, a supply chip is generally installed on the printing supply. For example, a toner cartridge chip is mounted on the toner cartridge and is used for storing relevant data of the toner cartridge, such as toner color, authentication code, serial number, remaining toner amount, page yield (maximum value of printable pages), printed pages, manufacturer, production date and the like.

In addition, in order to improve the authentication capability of the consumable chip, the printing device manufacturer may frequently upgrade the firmware of the printing device. For the sold printing equipment, applying a new authentication mode to the printing equipment in a firmware pushing and user downloading and installing mode; for printing devices that have not been sold or are in production, the latest firmware is applied to the printing device and then sold. New authentication methods often include new instructions, black lists of serial numbers, reading more data, etc. However, if the consumable chip on the sold printing consumable is not upgraded correspondingly, it is likely that the consumable chip cannot be identified by the printing apparatus, and the printing consumable cannot be used.

In the existing production standard, the printing consumables are usually packaged by wrapping with a plastic bag or a plastic film and then placed in a packaging box. It can be understood that if the printing consumables in the packaging box need to be upgraded, the packaging box, the plastic bag or the plastic film of the printing consumables need to be detached so as to access the consumable chip by utilizing the upgrading device. And after the upgrading is finished, the printing consumables are wrapped and packaged by plastic bags or plastic films and then placed into a packaging box. However, in the whole upgrading process, the package needs to be removed and then repackaged, which not only makes the upgrading process tedious and increases the labor cost for upgrading, but also wastes a part of packaging materials.

Another consumable chip upgrading mode in the related art is to set a window on the packaging box, and upgrade the consumable chip through the window. However, in order to upgrade the consumable chip, a larger window may need to be opened, which may cause great influence on the sealing performance and the anti-collision performance of the package. In addition, to the position of consumptive material chip apart from the packing carton outward appearance package far away, upgrading equipment need set up long and thin connector, and the contact on the consumptive material chip is less, brings the difficulty for counterpoint contact and fixed chip.

To the problem of the interior consumptive material chip of packing carton be not convenient for upgrade among the prior art, this application embodiment provides an upgrading solution of consumptive material chip, need not to set up great window on the packing carton, can accomplish the data input of consumptive material chip, and then accomplish the upgrading of consumptive material chip. When guaranteeing packing carton leakproofness, upgrading equipment also need not strictly to counterpoint the contact of consumptive material chip. The details will be described below.

Referring to fig. 1, a schematic diagram of a frame structure of a consumable chip provided in an embodiment of the present application is shown. As shown in fig. 1, the consumable chip provided by the embodiment of the present application includes a power module 101, a control circuit 102, and a photoelectric conversion module 103. The power module 101 is connected to a power input end of the control circuit 102, and the power module 101 is configured to provide power to the control circuit 102; the photoelectric conversion module 103 is connected with a signal input end of the control circuit 102, and the photoelectric conversion module 103 is configured to receive an optical communication signal and convert the optical communication signal into an electrical communication signal; the control circuit 102 is configured to receive the electrical communication signal and update the data stored in the control circuit 102 according to the electrical communication signal.

It can be understood that the authentication data of the consumable chip is stored in the control circuit 102, the data in the control circuit 102 is updated by upgrading the consumable chip, and the data stored in the control circuit may include information about the consumable chip, and may also include program instructions and program codes executed by the consumable chip. In addition, since the optical signal cannot provide power to the control circuit 102, the power module 101 is required to be disposed on the consumable chip for supplying power to the control circuit 102 in the embodiment of the present application. The power module 101 may be a battery built into the consumable chip.

In this application embodiment, realize the information input of consumptive material chip through light signal, need not to set up great window on the package material, guarantee the leakproofness of package material. In addition, the optical signals can be transmitted for a longer distance, and the light spots of the optical signals are larger (generally larger than the contact area of the consumable chip), so that accurate alignment is not needed during information input, and the position requirement of the consumable chip in the packaging material is reduced. The packaging material can be a packaging bag or a packaging box, and the embodiment of the application does not limit the packaging material.

In practical applications, the printing supplies may take a long time to be used. During this period, if the power module 101 keeps supplying power to the control circuit 102, the power of the battery is wasted, and even the power of the battery is exhausted. If the electric quantity of the battery is exhausted, the photoelectric conversion module 103 cannot work, and then the consumable chip cannot be upgraded.

In view of this problem, in a possible implementation manner, the consumable chip provided in the embodiment of the present application further includes a power management module. Referring to fig. 2, a schematic view of a structural framework of another consumable chip provided in the embodiment of the present application is shown. As shown in fig. 2, the power module 101 is connected to a power input terminal of the control circuit 102 through the power management module 104; the power management module 104 is configured to receive a power control signal, and control a connection state between the power module 101 and the control circuit 102 according to the power control signal, where the connection state includes connection or disconnection.

In an alternative embodiment, the power control signal may comprise a control signal triggered externally by the consumable chip, or may comprise a control signal triggered by the control circuit 102 internal to the consumable chip. For convenience of explanation, the control signal triggered by the external of the consumable chip is referred to as a first power control signal, and the control signal triggered by the internal control circuit 102 of the consumable chip is referred to as a second power control signal. Specifically, the power management module 104 is connected to a power control terminal of the control circuit 102, and the control circuit 102 may send a second power control signal to the power management module 104 through the power control terminal.

It is understood that the connection state of the power module 101 and the control circuit 102 includes a connection state and a disconnection state. Accordingly, the power control signal includes a power on signal and a power off signal.

In the initial state, the power module 101 and the control circuit 102 are in the disconnected state, and the control circuit 102 cannot operate. When the communication with the consumable chip is needed, a first power supply communication signal needs to be triggered from the outside, the power supply management module 104 controls the communication between the power supply module 101 and the control circuit 102 according to the first power supply communication signal, the power supply module 101 supplies power to the control circuit 102, and the control circuit 102 starts to work. After the control circuit 102 starts to operate, a second power connection signal may be sent to the power management module 104 through the control circuit 102, and the power module 101 is controlled to be connected to the control circuit 102 according to the second power connection signal. At this time, if the external device stops triggering the first power connection signal, the power module 101 and the control circuit 102 still maintain a connection state, so that the power module 101 can continuously supply power to the control circuit 102.

In addition, after the consumable chip completes information input, a power off signal can be sent to the power management module 104 through the control circuit 102, and the power management module 104 controls the power module 101 to be disconnected from the control circuit 102.

In the embodiment of the present application, the power management module 104 controls connection or disconnection of the power module 101. That is, the power module 101 does not always supply power to the control circuit 102, but selectively supplies power to the control circuit 102 according to the user's needs. For example, when communication with a consumable chip is required, the control power module 101 supplies power to the control circuit 102; after the communication with the consumable chip is completed, the control power module 101 stops supplying power to the control circuit 102, avoiding using the power during the non-communication period. This mode can guarantee that the consumptive material chip has sufficient electric quantity in the longer time, and avoids setting up the large capacity battery in the consumptive material chip to reduce cost, reduce the volume of consumptive material chip.

Referring to fig. 3, a schematic circuit diagram of a consumable chip according to an embodiment of the present disclosure is shown. As shown in fig. 3, in the embodiment of the present application, the power management module 104 includes a second controllable switching device T1, a photoresistor Rg, and a capacitor C1; the control circuit 102 includes a power control terminal P1, a power input terminal P2, and a signal input terminal P3; the power supply module 101 includes a battery Pw for supplying power; the photoelectric conversion module 103 includes a photodiode PD for optical coupling. It should be noted that the photoresistor Rg is the first controllable switching device according to the embodiments of the present application, and it is understood that the first controllable switching device may be a photodiode or a phototriode, etc. in addition to the photoresistor. In addition, the first controllable switching device may be other types of switching devices besides the photosensitive device, and the embodiment of the present application is not limited thereto.

The negative electrode of the battery Pw is grounded, the positive electrode of the battery Pw is connected to the power input end P2 of the control circuit 102 through a photoresistor Rg, and the photoresistor Rg is configured to receive a light start signal (i.e., the aforementioned first power control signal) emitted from the outside, and control the connection state between the battery Pw and the control circuit 102 according to the intensity of the received light start signal. The second controllable switch device T1 includes an input end, an output end, and a control end, the input end and the output end of the second controllable switch device T1 are respectively connected to two ends of the photoresistor Rg, the control end of the second controllable switch device T1 is connected to the power control end P1 of the control circuit 102, and the control end of the second controllable switch device T1 is configured to receive a second power control signal input by the control circuit 102, and control a connection state between the power module 101 and the control circuit 102 according to the second power control signal. One end of the capacitor C1 is grounded, and the other end of the capacitor C1 is connected to the power input end P2 of the control circuit 102; one end of the photodiode PD is grounded, and the other end is connected to the signal input terminal P3 of the control circuit 102. The operation principle thereof will be explained below.

Since the optical signal cannot directly supply power to the control circuit 102, the consumable chip provided by the embodiment of the present application includes a battery Pw thereon, and the battery Pw is used for supplying power to the control circuit 102. In addition, in order to avoid the power consumption and the service life of the battery Pw being wasted due to the long-time power supply of the battery Pw to the control circuit 102, the embodiment of the present application designs a protection mechanism for the battery Pw, and the power management module 104 controls the connection or disconnection between the battery Pw and the control circuit 102.

In a specific implementation, the power management module 104 includes a second controllable switch device T1, a photoresistor Rg, and a capacitor C1. It can be understood that in the initial state, the second controllable switching device T1 is in the off state, and the photoresistor Rg is in the high impedance state when not receiving the illumination with sufficient intensity, and the dark resistance thereof can reach 1.5M Ω, therefore, the battery Pw cannot supply power to the control circuit 102. When the consumable chip is irradiated with light of sufficient intensity through the upgrading device or other signal input devices (here, light satisfying the condition is defined as a light start signal), the resistance of the photoresistor Rg is reduced, and the current of the battery Pw can flow through the photoresistor Rg to gradually charge the capacitor C1. When the capacitor C1 is charged to the operating voltage of the control circuit 102, the control circuit 102 starts operating. At this time, the control circuit 102 may send a control signal to the second controllable switching device T1 through the port P1 of the power control terminal, and close the second controllable switching device T1, so that the battery Pw may directly provide power to the control circuit 102 through the second controllable switching device T1. In other words, at this time, the irradiation of the light start signal is stopped, and the battery Pw and the control circuit 102 are still in a connected state. When light start signal is a stable, light signal that the light intensity is high, in this embodiment, also can not set up electric capacity C1, because the resistance of photo resistance Rg has fallen to enough low this moment, therefore the partial pressure on the photo resistance Rg is little, and battery Pw can directly supply power to control circuit 102 through photo resistance Rg. The setting of visible electric capacity C1 can reduce the requirement to the stability of light actuating signal, intensity to do benefit to the steady operation of consumptive material chip, have great inclusion to the influence that light actuating signal received environment, packing carton when the packing carton is arranged in to the consumptive material chip.

In the embodiment of the present application, the battery Pw does not start to supply power to the control circuit 102 after production, but starts to supply power to the control circuit 102 when receiving a predetermined optical signal, so that the power of the battery Pw can be saved, the power of the battery Pw is prevented from being used in a non-optical communication period, a consumable chip has sufficient power during optical communication, and communication abnormality is prevented. Meanwhile, the design scheme is adopted, a large-capacity battery Pw does not need to be arranged in the consumable chip, and therefore cost is reduced.

After the control circuit 102 completes the power-on start, the photodiode PD enters an operating state. In the embodiment of the present application, the photodiode PD is reversely biased and connected to the signal input terminal P3 of the control circuit 102, i.e. the P pole is connected to the low voltage, and the N pole is connected to the high voltage. When there is no light irradiation, the reverse resistance of the photodiode PD is large, the reverse current is small, and the photodiode PD is in an off state. The reverse current, also called dark current, is very small. When the photodiode is irradiated by light, photons bombard near a PN junction in the photodiode PD to absorb energy of the PN junction to generate electron-hole pairs, so that the minority carrier concentration of the P region and the N region is greatly increased, and therefore under the action of an external reverse bias voltage and an internal electric field, the minority carrier transition blocking layer of the P region enters the N region, the minority carrier transition blocking layer of the N region enters the P region, and the reverse current passing through the PN junction is greatly increased, so that a photocurrent is formed, and the photocurrent is much larger than dark current. Therefore, the consumable chip can be upgraded based on the input of information by the photodiode PD.

In a specific implementation, the control circuit 102 includes a voltage detection unit and a signal identification unit; the voltage detection unit is used for detecting a voltage signal in the electric communication signal; the signal identification unit is used for identifying communication data corresponding to the voltage signal, and the communication data is used for updating the data stored in the control circuit 102, so that the consumable chip is upgraded. The voltage detection unit comprises a load resistor, the load resistor is connected with the photoelectric conversion module 103 in series, and the voltage signal is the voltage at two sides of the load resistor; the signal identification unit comprises a first arithmetic unit, a second arithmetic unit and a third arithmetic unit; the first arithmetic unit is used for comparing the voltage signal with a first reference voltage and outputting a first level signal, wherein the first level signal is at a high level when the voltage signal is greater than the first reference voltage, and the first level signal is at a low level when the voltage signal is less than the first reference voltage; the second arithmetic unit is used for comparing the voltage signal with a second reference voltage and outputting a second level signal, wherein the second level signal is at a high level when the voltage signal is greater than the second reference voltage, and the second level signal is at a low level when the voltage signal is less than the second reference voltage; the third arithmetic unit is used for generating communication data according to the first level signal and the second level signal; wherein the first reference voltage is greater than the second reference voltage. The following detailed description is made with reference to the accompanying drawings.

Referring to fig. 4, a schematic diagram of a photocurrent detection circuit according to an embodiment of the present application is provided. As shown in fig. 4, when a reverse voltage is applied to the photodiode PD through the battery Pw, the load resistor RL is connected in series with the photodiode PD, and an optical signal received by the photodiode PD can be converted into a current or voltage signal by detecting an output voltage Vo generated after flowing through the load resistor RL. Therefore, the data writing and upgrading of the consumable chip can be realized by irradiating the photodiode PD on the consumable chip with the changed light to transmit information to the consumable chip through the changed light signal (here, the light satisfying this condition is defined as the optical communication signal). Here, the load resistor RL connected in series with the photodiode PD in fig. 4 may be provided in the control circuit 102, or may be provided outside the control circuit 102, for example, connected in series between the signal input terminal P3 of the control circuit 102 and the ground signal GND. The embodiment of the present application does not limit the specific implementation manner thereof.

After different output voltages Vo are obtained through illumination with different intensities, signal characteristics of the output voltages Vo need to be detected, and then the output voltages Vo are converted into corresponding data according to the characteristics of the output voltages Vo, so that the data in the control circuit 102 are updated.

The signal identifying unit in the control circuit 102 includes a first operator and a second operator, which may be an operational amplifier or a voltage comparator, to which the output voltage Vo is input, so that the optical signal received by the photodiode PD can be converted into a high level and a low level representing a digital signal.

Fig. 5 is a schematic diagram of a voltage detection and identification circuit provided in an embodiment of the present application, and fig. 6 is a schematic diagram of reference voltage setting provided in the embodiment of the present application, as shown in fig. 5 and fig. 6, an output voltage Vo may be respectively input to a first operational amplifier A1 and a second operational amplifier A2, where the first operational amplifier A1 and the second operational amplifier A2 preset different reference voltages, which are respectively a first reference voltage Vref1 and a second reference voltage Vref2, and in the embodiment shown in fig. 6, the first reference voltage Vref1 is higher than the second reference voltage Vref2. For the first operational amplifier A1, when the output voltage Vo is higher than the first reference voltage Vref1, the output terminal OUT1 thereof outputs a high level, and on the contrary, when the output voltage Vo is lower than the first reference voltage Vref1, the output terminal OUT1 thereof outputs a low level; with the second operational amplifier A2, when the output voltage Vo is higher than the second reference voltage Vref2, the output terminal OUT2 thereof outputs a high level, and conversely, when the output voltage Vo is lower than the second reference voltage Vref2, the output terminal OUT2 thereof outputs a low level.

Referring to fig. 7, a schematic diagram comparing input and output waveforms of a voltage detection circuit according to an embodiment of the present disclosure is shown. Three waveforms of the output voltage Vo, the output terminal OUT1, and the output terminal OUT2 are shown in fig. 7. The output voltage Vo is a load voltage obtained by flowing through the load resistor RL after different photocurrents generated by the intensity of the optical signal are received by the photodiode PD in fig. 4. In the embodiment of the present application, the light intensity of the light corresponding to the high level (e.g., 4 to 5V) in the output voltage Vo is defined as high strong light, the light intensity of the light corresponding to the medium level (e.g., 2 to 3V) in the output voltage Vo is defined as medium strong light, and the light intensity of the light corresponding to the low level (e.g., 0 to 1V) in the output voltage Vo is defined as weak light or no light. Therefore, when the output voltage Vo in fig. 7 is input to the voltage detection identification circuit shown in fig. 5, the waveforms of the output ends OU1 and OUT2 obtained through comparison of the first operational amplifier A1 and the second operational amplifier A2 are as shown in fig. 7. It can be understood that the waveform of the output terminal OUT1 is a clock signal transmitted by the optical signal, the waveform of the output terminal OUT2 is a data signal transmitted by the optical signal, and if a binary number "1" is used to represent a high level and a binary number "0" is used to represent a low level, the waveform of the output terminal OUT2 is identified by using the waveform of the output terminal OUT1, and then the data "10010" transmitted to the consumable chip by the light can be obtained. Therefore, in the embodiment of the present application, the signal identification unit further includes a third operator, and the third operator is configured to identify the waveform of the output terminal OUT2 by using the waveform of the output terminal OUT1, so as to obtain the communication data. Accordingly, the light source in the embodiment of the present application may include high light through which the clock signal may be transmitted, medium light through which the data signal may be transmitted, and no/low light.

It should be noted that the above embodiments are only specific implementations of the consumable chip listed in the embodiments of the present application, and those skilled in the art can make adaptation according to actual needs, which all fall within the protection scope of the present application.

For example, the photosensitive device in the power management module 104 may be a photosensitive diode or a phototriode, etc. in addition to the photosensitive resistor Rg; the second controllable switching device T1 in the power management module 104 may be a field effect transistor or a transmission gate circuit, etc. in addition to the triode; the photoelectric conversion module 103 may be a photo resistor Rg or a photo transistor, in addition to the photo diode PD.

Specifically, the printing supplies (e.g., the imaging cartridge 810) may be an ink cartridge, a powder cartridge, a toner cartridge, or other printing supplies, and the like, and the embodiment of the present application is not limited to a specific form thereof. The printing consumables also comprise other structures or modules besides consumable chips for recording information and identifying authentication. For example, the ink cartridge includes an air inlet, an ink outlet, a positioning member, a mounting member, and the like, in addition to the consumable chip.

Corresponding with the printing consumables in the embodiment, this application embodiment still provides a packing material of printing consumables, the packing material is used for packing the printing consumables to in transit or sell. For example, the ink cartridge, the powder cartridge, or the cartridge is packaged by a packaging box. The packaging material is provided with a burning window, and the position of the burning window is configured as follows: when the printing consumables are arranged in the packaging material in the above embodiment, the burning window corresponds to the photoresistor Rg and/or the photoelectric conversion module 103 of the consumable chip on the printing consumables.

In a possible implementation manner, in order to improve the sealing performance of the packing material, the burning window may be sealed by a sealing member. It is understood that the sealing member should be made of a material that is transparent to light. For example, using a completely transparent plastic film or sheet.

In a possible implementation manner, in order to reduce the influence of ambient light, the sealing element may also be made of a black or dark transparent/light-transmitting material, which can block part of light, reduce the transmittance of the burning window, and further reduce the influence of ambient light. The following detailed description is given with reference to specific examples.

Referring to fig. 8, a schematic diagram of a packaging material structure of a printing consumable provided in an embodiment of the present application is shown. In fig. 8, the printing supplies are imaging box 810, the packaging material includes vacuum bag 820 and packaging box 830, and imaging box 810 is placed in paper packaging box 830 after being packaged in evacuated vacuum bag 820. The packing material can also be a common plastic bag without air extraction instead of an air-extracted vacuum bag, and the vacuum property and the light transmittance can be selected according to the actual requirement without limitation. On the packing box 830, a burning window 831 is provided. The position of the burning window 831 corresponds to the position of the consumable chip 811 on the imaging cartridge 810, specifically, the position of the light receiving unit 812 on the consumable chip 811. In one possible implementation manner, the light receiving unit 812 includes a photo resistor Rg and a photo diode PD in the embodiment shown in fig. 3. That is to say, the photo resistor Rg and the photo diode PD are packaged together, so that the light receiving positions are concentrated, and the smaller burning window 831 can be corresponded. Corresponding to the printing consumables in the above embodiments, the embodiment of the present application further provides a printing apparatus, where the printing apparatus is provided with the consumable chip 811 described in the above embodiments. Specifically, the printing device may be an inkjet printer, a laser printer, a multifunction machine, or other printing devices, and the like, and the embodiment of the present application does not limit the specific form thereof.

Corresponding to the printing consumables in the above embodiments, the embodiment of the present application further provides an information input device, where the information input device includes an optical signal output module, and the optical signal output module is configured to send an optical start signal and/or an optical communication signal to the consumable chip 811. In some possible embodiments, the information input device may also be referred to as an upgrade device 840.

It is understood that the optical enable signal is used to trigger the control circuit 102 to supply power, and the optical communication signal is used to write data into the consumable chip 811. Of course, in some possible embodiments, the optical signal output module may send only an optical activation signal or only an optical communication signal. For example, if the power supply of the consumable chip 811 is configured to be continuously powered, the information input device need not provide a light initiation signal; alternatively, the device for transmitting the optical activation signal is a separate device, and the device for transmitting the optical activation signal need not provide the optical communication signal.

Referring to fig. 9, a schematic view of an upgrade scenario of a printing consumable according to an embodiment of the present application is shown. In the embodiment shown in fig. 9, the information input device is an upgrade device 840, and the upgrade device 840 is provided with an optical transmitter 841, which is an optical signal output module. Upgrade apparatus 840 may transmit light to consumable chip 811 through light emitter 841 to enable battery Pw on consumable chip 811 and transmit data to be written to consumable chip 811. Thus, the light emitter 841 of the upgrade apparatus 840 may have two different operation states. In the first working state, the light emitter 841 transmits a light starting signal to the consumable chip 811, so that the consumable chip 811 is started to enter the working state; in the second operating state, the light emitter 841 transmits a light communication signal to the consumable chip 811 to write data to the consumable chip 811. The light emitter 841 may be a light emitting device such as an LED, a laser, a tungsten lamp, etc. In the second working state, the upgrade apparatus 840 converts the data to be written into the consumable chip 811 into the driving signal of the light emitter 841 through the internal light modulation circuit, and transmits the data to the consumable chip 811 by using the changed light signal. Because the consumable chip receives the optical start signal, the capacitor charging requires some time to reach the preset working voltage of the consumable chip, so the time interval from the first working state to the second working state of the upgrading device 843 can be set according to the charging time of the capacitor. It will be appreciated that the vacuum bag 820 and burn openings in the wrapper need to be light permeable. In addition, in order to reduce the influence of ambient light, the vacuum bag 820 may be made of a black or dark transparent/transparent material, or the burn opening may be sealed or shielded by the black or dark transparent/transparent material.

In addition, in order to save the power of the battery Pw, in addition to the above-mentioned requirement that the battery Pw supplies power to the consumable chip 811 only when receiving a predetermined optical signal (for example, the above-mentioned optical start signal), the following settings may be made for the use of the battery Pw: when the received optical signal stops, the consumable chip 811 determines whether the currently processed transaction has ended, and after the predetermined command processing ends, in the illustration of fig. 3, the control circuit 102 outputs a low level to the control terminal of the second controllable switching device T1 in the power management module 104, and turns off the second controllable switching device T1, thereby turning off the power supply of the battery Pw to the control circuit 102 through the second controllable switching device T1. In other embodiments, a timer may be disposed in the consumable chip 811, when the light received by the light receiving unit 812 is no longer changed or does not receive light with a preset intensity, the timer starts to count, and when the timer reaches a preset value, the control circuit 102 outputs a low level to the control terminal of the second controllable switching device T1 to turn off the power supply of the battery Pw to the control circuit 102. At this moment, because the photoresistor Rg no longer receives the light signal, consequently the photoresistor Rg is also in the high resistance state, and battery Pw can no longer supply power to control circuit 102 through the photoresistor Rg yet, consequently can ensure just to use the electric quantity of battery Pw under the condition that control circuit 102 needs, has improved the utilization efficiency of battery Pw.

In addition, the optical communication provided by the embodiment of the application is unidirectional communication sent from the upgrading device to the consumable chip. For example, in fig. 9, only the optical signal is sent from the upgrade apparatus to the consumable chip, and therefore, the consumable chip cannot feed back whether the optical signal is received or not and whether the received optical signal is normal or not to the upgrade apparatus through the optical signal.

Therefore, in order to know whether the consumable chip has been upgraded, an indicator such as an LED (or an acousto-optic means such as a buzzer, a light or a combination thereof) may be disposed on the consumable chip, and the LED is connected to the control circuit 102 shown in fig. 3. In the process of optical communication and after the chip is upgraded, the display/broadcast mode of the LED is changed, and the LED is easy to identify by a user. For example, during optical communication, the control circuit 102 may control the LED to blink; when the optical communication is finished, the control circuit 102 determines that the received signal is abnormal or the upgrade cannot be completed according to the signal, which results in the failure of the upgrade, and the control circuit 102 may control the LED to be normally on for several seconds, for example, 1 second. When the upgrade is successful, the control circuit 102 may control the LED to automatically go off.

In this application embodiment, optical coupling elements such as photoresistor Rg and photodiode PD can be for the sensitive element to visible light, also can be the optical coupling element that only is sensitive to infrared ray, ultraviolet lamp part wave band, when adopting the optical coupling element of different grade type, need match corresponding light source and carry out optical communication. In consideration of the fact that the packaging material is difficult to avoid weak ambient light such as visible light and lamplight in actual transportation and use environments, in order to reduce the influence of the ambient light on the photoresistor Rg and the photodiode PD, a film or a thin plate with a light-weakening effect, such as a gray black transparent film, a dark transparent PVC plate, and the like, may be added to the burning opening. Or, a coating/film for reducing light is additionally arranged on the photoresistor Rg and the photodiode PD to reduce the influence of the ambient light. At this point, light emitter 841, which is used in an upgraded device, needs to have increased light brightness or power to counteract the effects of these reduced light coatings or films or sheets.

Corresponding to the embodiment, the application also provides a communication method of the consumable chip and the information input equipment. The method can be applied to the consumable chip and the information input device in the above embodiments. Referring to fig. 10, a schematic flow chart of a communication method between a consumable chip and an information input device is further provided in the present application. As shown in fig. 10, it mainly includes the following steps.

Step S1001: the information input equipment sends an optical communication signal to the consumable chip, and the optical communication signal is used for bearing communication data.

Step S1002: the consumable chip responds to the optical communication signal sent by the information input equipment and converts the optical communication signal into an electric communication signal.

Step S1003: and the consumable chip updates the stored data according to the electric communication signal.

In practical applications, the printing supplies may take a long time to be used. During this period, if the power module 101 keeps supplying power to the control circuit 102 all the time, the power of the battery Pw is wasted, and even the power of the battery Pw is exhausted. If the power of the battery Pw is exhausted, the photoelectric conversion module 103 cannot work, and thus the consumable chip cannot be upgraded.

Aiming at the problem, the application also provides another communication method of the consumable chip and the information input equipment. Referring to fig. 11, a schematic flow chart of a communication method between another consumable chip and an information input device according to an embodiment of the present application is provided. As shown in fig. 11, it further includes the following steps before step S1001 shown in fig. 10.

Step S1101: the consumable chip responds to the power supply connection signal and controls the consumable chip to be connected with the power supply.

Specifically, the power management module 104 of the consumable chip responds to a first power connection signal sent by an information input device and controls the power module 101 to be connected with the control circuit 102 according to the first power connection signal; the power management module 104 of the consumable chip responds to the second power connection signal sent by the control circuit 102 and controls the power module 101 to be connected with the control circuit 102 according to the second power connection signal.

In the initial state, the power module 101 and the control circuit 102 are in the disconnected state, and the control circuit 102 cannot operate. When communication with the consumable chip is required, a first power supply communication signal needs to be triggered from the outside, the power management module 104 controls the communication between the power module 101 and the control circuit 102 according to the first power supply communication signal, the power module 101 supplies power to the control circuit 102, and the control circuit 102 starts to work. After the control circuit 102 starts to operate, a second power connection signal may be sent to the power management module 104 through the control circuit 102, and the power module 101 is controlled to be connected to the control circuit 102 according to the second power connection signal. At this time, if the external device stops triggering the first power connection signal, the power module 101 and the control circuit 102 still maintain a connection state, so that the power module 101 can continuously supply power to the control circuit 102.

In addition, after the information input of the consumable chip is completed, a power off signal can be sent to the power management module 104 through the control circuit 102, and the power management module 104 controls the power module 101 to be disconnected from the control circuit 102.

In the embodiment of the present application, the power management module 104 controls the connection or disconnection of the power module 101, so as to ensure that the consumable chip has sufficient electric quantity for a long time, and avoid setting a large-capacity battery Pw in the consumable chip, thereby reducing the cost.

In order to facilitate a better understanding of the technical solution by those skilled in the art, the communication method according to the embodiment of the present application will be described in detail below with reference to the consumable chip in the embodiment illustrated in fig. 3.

Referring to fig. 12, a schematic flow chart of a communication method between another consumable chip and an information input device according to an embodiment of the present application is shown. The method can be applied to the upgrading device and the consumable chip described in fig. 9, that is, in the embodiment of the present application, the information input device is specifically an upgrading device, and the internal circuit structure of the consumable chip can refer to fig. 3. As shown in fig. 12, it mainly includes the following steps.

Step S1201: the upgrading device sends a light starting signal to the consumable chip.

After the consumable chip is produced, when the consumable chip is not irradiated with light, the battery Pw provided on the consumable chip does not supply power to the control circuit 102 of the consumable chip, and the consumable chip is in a stopped state. When the data of the consumable chip is required to be rewritten by the upgrading device, the optical starting signal can be sent to the consumable chip through the optical transmitter on the upgrading device, namely, the light with enough intensity is irradiated to the optical receiving unit on the consumable chip.

Step S1202: and the photosensitive resistor on the consumable chip receives the light starting signal and is communicated with the battery and the control circuit.

The light receiving unit on the consumable chip comprises a photoresistor Rg, and the photoresistor Rg is irradiated by light, so that the resistance is reduced. At this time, the power current provided by the battery Pw may flow through the photo resistor Rg to charge the capacitor C1. The voltage of the capacitor C1 will gradually increase with the charging time. When the voltage of the capacitor C1 is charged to a predetermined value by the battery Pw, the control circuit 102 of the consumable chip starts operating. The predetermined value here refers to the lowest operating voltage of the control circuit 102, for example, 3V, 4V, or 5V.

Step S1203: the power supply management module responds to a second power supply communication signal sent by the control circuit and communicates the battery and the control circuit according to the second power supply communication signal.

When the control circuit 102 starts to work, the control circuit 102 sends a control signal to the second controllable switching device T1 through the port P1 of the power control terminal, and closes the second controllable switching device T1, so that the battery Pw can directly provide power to the control circuit 102 through the second controllable switching device T1. In other words, at this time, the irradiation of the light start signal is stopped, and the battery Pw and the control circuit 102 are kept in a connected state.

In addition, the manner of controlling the second controllable switching device T1 may differ according to different embodiments. For example, when the control circuit 102 is a hardware logic circuit, after the logic circuit starts to operate, it sends a control signal to the control terminal of the second controllable switching device T1, so as to close the second controllable switching device T1. When the control circuit 102 implements the corresponding control function by the CPU executing the program instructions stored in the memory of the control circuit 102, the program instructions will send a control signal to the power control terminal P1 connected to the second controllable switching device T1 after starting to operate, so as to close the second controllable switching device T1. After the second controllable switching device T1 is closed, the battery Pw can stably supply power to the control circuit 102 directly.

Step S1204: and the upgrading equipment sends an optical communication signal to the consumable chip, wherein the optical communication signal is used for bearing communication data.

The light receiving unit on the consumable chip also comprises a photodiode PD. With the power supply, the control circuit 102 of the consumable chip starts to operate, and the photodiode PD reversely biased by the control circuit 102 is also in an operating state. At the moment, the information input of the consumable chip is realized by sending the modulated optical signal to the consumable chip through the upgrading device.

Step S1205: the photoelectric conversion module responds to an optical communication signal sent by the information input equipment and converts the optical communication signal into an electric communication signal.

When the upgrade apparatus irradiates the photodiode PD with light, the changed light may cause the photodiode PD to generate a changed reverse current (photocurrent), thereby achieving conversion of an optical signal into an electrical signal.

Step S1206: the control circuit updates the data stored in the control circuit according to the electrical communication signal.

In a possible implementation manner, the control circuit 102 of the consumable chip may identify the current generated by the photodiode PD by means of detecting the current flowing through the photodiode PD through a current detection resistor, so that the current may be converted into a digital signal, and the control circuit 102 may write corresponding data into a memory in the control circuit 102 or transmit control information, a verification command, an encryption command, and the like to the control circuit 102 according to the converted digital signal.

In another possible implementation manner, the illumination intensity received by the photodiode PD affects the voltage on both sides of a load resistor connected in series with the photodiode PD, so that the control circuit 102 of the consumable chip can convert the voltage signal into a digital signal by detecting the voltage signal on both sides of the load resistor, and further write corresponding data into a memory in the control circuit 102, or transmit control information, a verification command, an encryption command, and the like to the control circuit 102.

Step S1207: the control circuit sends a power off signal to the power management module.

After the information input of the consumable chip is completed, a power supply disconnection signal can be sent to the power supply management module 104 through the control circuit 102, the power supply management module 104 controls the battery Pw to be disconnected from the control circuit 102, and the battery Pw stops supplying power to the control circuit 102, so that the power supply is saved.

Specifically, when the received optical signal is stopped, the consumable chip determines whether the currently processed transaction has ended, and after the predetermined command processing ends, the control circuit 102 sends a power off signal to the power management module 104 to cut off the second controllable switching device T1, thereby cutting off the path of the battery Pw to the control circuit 102 through the second controllable switching device T1. In other embodiments, a timer may be disposed in the consumable chip, when the light receiving unit receives no more changed light or light with a preset intensity, the timer starts to count time, and when the preset value is counted, the control circuit 102 outputs a power off signal to the second controllable switch device T1 to turn off the power supply of the battery Pw to the control circuit 102. Because the light signal is no longer received to photo resistance Rg, consequently photo resistance Rg also is in the high resistance state, and battery Pw can no longer supply power to control circuit 102 through photo resistance Rg, consequently can ensure just to use the electric quantity of battery Pw under the condition that control circuit 102 needs, has improved the utilization efficiency of battery Pw.

In addition, the optical communication provided by the embodiment of the application is unidirectional communication sent from the upgrading device to the consumable chip. In order to know whether the consumable chip has been upgraded, an indicator (or an acousto-optic means such as a buzzer, a light or a combination thereof) such as an LED may be disposed on the consumable chip, and the LED is connected to the control circuit 102 shown in fig. 3. In the process of optical communication and after the chip is upgraded, the display/broadcast mode of the LED is changed, and the LED is easy to identify by a user. For example, during optical communication, the control circuit 102 may control the LED to flash; when the optical communication is finished, the control circuit 102 determines that the received signal is abnormal or the upgrade cannot be completed according to the signal, which results in the failure of the upgrade, and the control circuit 102 may control the LED to be normally on for several seconds, for example, 1 second. When the upgrade is successful, the control circuit 102 may control the LED to automatically go off.

For different communication modes, the communication interface/port of the consumable chip can adopt different circuit forms. For contact communication, the communication interface is a signal contact point (contact for short); for contactless communication, the communication interface may then comprise an antenna or a coil for wireless communication.
