Fig. 1 is a schematic diagram of a consumable wireless interaction system provided in an embodiment of the present application, and as shown in fig. 1, a read/write device 100 includes: the antenna comprises a first main control module 120, a power module 110, a first antenna module 150 and a second antenna module 160, wherein the power module 110 is respectively connected with the first antenna module 150 and the first main control module 120, the first main control module 120 is also connected with the second antenna module 160, and the first antenna module 150 and the second antenna module 160 can be directly powered by the power module 110 or indirectly powered by the first main control module 120.

A power module 110 for supplying power; specifically, the power module 110 is responsible for converting an externally input voltage into a working voltage required by other modules in the read-write device 100, and the power source of the power module 110 may also be power supply power of the read-write device 100 itself, such as a storage battery.

The first main control module 120 is a central processing module of the read/write device 100, and is responsible for hardware control, data processing, and communication control of each module.

In the read-write apparatus 100, the first antenna module 150 is used for performing wireless power supply, and the second antenna module 160 is used for performing wireless communication. The first master control module 120 is configured to transmit the electrical energy to the consumable chip 200 in the form of radio frequency electrical energy through the first antenna module 150; in addition, the first main control module 120 is further configured to enable wireless data communication with the consumable chip 200 through the second antenna module 160.

The first antenna module 150 and the second antenna module 160 are independently disposed, and a first frequency band in which the first antenna module 150 operates is different from a second frequency band in which the second antenna module 160 operates.

Correspondingly, referring to fig. 1, the present embodiment further provides a consumable chip 200, where the consumable chip 200 includes: a second main control module 220, a third antenna module 250 and a fourth antenna module 260, wherein the second main control module 220 is electrically connected with the third antenna module 250 and the fourth antenna module 260 respectively.

The second main control module 220 is a central processing module of the consumable chip 200, and is responsible for hardware control, data processing, and communication control of each module.

In the consumable chip 200, the third antenna module 250 is used for wireless power supply, i.e. capturing radio frequency power, and the fourth antenna module 260 is used for wireless data communication. The second main control module 220 is configured to receive the radio frequency power transmitted by the read-write device 100 through the third antenna module 250, and output power supply power based on the radio frequency power, where the power supply power is used by the second main control module 220 and other power utilization modules in the consumable chip 200; in addition, the second master control module 220 is further configured to implement wireless data communication with the read-write device 100 through the fourth antenna module 260;

the third antenna module 250 and the fourth antenna module 260 are independently disposed, and a third frequency band in which the third antenna module 250 operates is different from a fourth frequency band in which the fourth antenna module 260 operates.

In this embodiment, two independent antenna modules are respectively arranged in the read-write device 100 and the consumable chip 200, and are respectively used for performing wireless power supply and wireless communication, so that the read-write device 100 and the consumable chip 200 can perform transmission of electric energy through the two antenna modules for performing wireless power supply, and communication data is transmitted through the two antenna modules for performing wireless communication, thereby the transmission of electric energy and communication data does not interfere with each other, thereby ensuring the stability of performing wireless power supply between the read-write device 100 and the consumable chip 200, and further ensuring the stability of performing wireless communication between the read-write device 100 and the consumable chip 200. In addition, the antenna for power supply and the antenna for wireless data communication adopt different frequency bands, so that the anti-interference capability is stronger, and the power supply and the data transmission are more stable and reliable.

In some embodiments, the consumable chip 200 further comprises: and a functional circuit module (not shown in the figure) directly/indirectly connected to the second main control module 220 for implementing a specific function of the consumable chip 200, such as a sensor circuit for detecting the remaining or usage amount of the consumable.

Because the position that different consumptive material chips 200 are located the consumptive material is different, and for making things convenient for the data update of consumptive material chip 200, it is most convenient to do the data update under the condition of need not taking out the consumptive material from consumptive material packing carton or packing carton, at this moment, the distance between third antenna module 250 of consumptive material chip 200 and first antenna module 150 is uncontrollable, in order to realize different consumptive materials, the data update under the different packing environment, in some embodiments of this application, read write equipment 100 has still set up the radio frequency electric energy regulatory function, it is concrete, set up regulating circuit in read write equipment 100, this regulating circuit can set up in first host system 120, also can be independent of first host system 120 and set up and be controlled by first host system 120. The adjusting circuit is configured to adjust the first antenna module 150 to adjust the energy amount of the rf power emitted from the first antenna module 150, so that the most suitable power can be provided to the consumable chip 200 according to different consumable signals, different use environments or packaging environments.

In some embodiments, a specific structure of the adjusting circuit in the read/write device 100 is explained by taking a case where the adjusting circuit is disposed independently from the first master control module 120 as an example.

Fig. 2 is a schematic structural diagram of a first adjusting circuit in an embodiment of the present invention, as shown in fig. 2, in some embodiments, the first antenna module 150 includes at least two sets of antenna branches with different parameters and/or different polarities, for example, the antenna branch 1, the antenna branch 2, …, the antenna branch i, and the like in fig. 2, and the energy of the rf electrical energy emitted by different antenna branches is different.

Correspondingly, the regulating circuit comprises: specifically, in the antenna switching circuit 144, a relay may be selected as a connector, a common terminal of the relay is connected to the power module 110, a control terminal of the relay is connected to the first main control module 120, and a selection terminal of the relay is connected to each antenna branch of the first antenna module 150, although other gating switches or logic control switches may also be used. Therefore, the first main control module 120 can select one antenna branch to communicate with the power module 110 under different conditions, so as to switch the antenna branches, and further adjust the energy of the radio frequency electric energy emitted by the first antenna module 150. The communication of the first antenna module 150 with the power module 110 may be direct or indirect.

After selecting different antenna branches, the first main control module 120 may perform error rate detection for wireless communication, and after performing error rate detection for all antenna branches, select and communicate an antenna branch with the lowest error rate, thereby improving the quality of wireless communication. When the homoenergetic normal communication can also be selected, comparatively middle antenna branch is selected as the power supply branch, the problem that the low-energy antenna branch cannot stably supply power due to external interference is prevented, and the problem that the electric energy is excessively consumed due to the use of an overhigh power supply antenna branch is also prevented.

In some embodiments, the parameters include one or more of antenna coil structural parameters, capacitance values across the antenna coil. The structural parameters of the antenna coil specifically include size parameters of the antenna coil, such as thickness, length, number of turns, and the like, and since the size parameters affect the Q value and the inductance value of the antenna coil, the energy of the radio frequency electric energy emitted by each antenna coil is different when the size parameters are different. The radio frequency electric energy can be influenced by different capacitance values and capacitors.

In this embodiment, the first master control module 120 is specifically configured to send a detection signal to the consumable chip 200 through the second antenna module 160, and gate corresponding antenna branches in different first antenna modules 150 when a feedback signal that meets a preset requirement and is returned by the consumable chip 200 is not received within a preset time, so as to adjust the energy of the radio frequency electric energy emitted by the first antenna modules 150.

The detection signal may be a request signal or a handshake signal, when the first main control module 120 receives a feedback signal indicating that the consumable signal 200 is correct within a preset time, it indicates that the first antenna module 150 provides stable power for the consumable chip 200, which indicates that the consumable chip 200 can correctly respond to a signal provided by the read/write device 100 to satisfy a condition of stable operation, and if a feedback signal satisfying a preset requirement and fed back by the consumable chip 200 is not received within the preset time, it indicates that the radio frequency power provided by the first antenna module 150 is not enough to enable the consumable chip 200 to normally operate or the provided radio frequency power is not suitable for the consumable chip 200 to maintain normal and stable operation, and at this time, the first main control module 120 gates different antenna branches to adjust the power provided for the consumable chip 200 to operate. The failure to receive the feedback signal satisfying the preset requirement fed back by the consumable chip 200 means: no feedback signal is received or the received feedback signal is not the correct signal.

It should be noted that, in this case, when the adjusting circuit is set independently of the first main control module 120, the gating may be completed through the antenna switching circuit 144, for example, the gating of different antenna branches may be completed through a relay or other switches; in addition, when the adjusting circuit is disposed in the first main control module 120, the adjusting circuit can be implemented by hardware, and can also be controlled by software.

In this embodiment, by providing a regulating circuit, such as the antenna switching circuit 144, the sensing effect between the antennas can be adjusted without moving the wireless chip, for example, by controlling the antennas to be inverted or selecting antenna branches with other parameters, so as to improve the sensing effect of wireless power supply and further improve the stability of wireless power supply.

In some embodiments, the read/write device 100 further comprises a second type of regulation circuit.

Fig. 3 is a schematic diagram of a second adjusting circuit in the embodiment of the present application, and as shown in fig. 3, the adjusting circuit includes a power control circuit 141 for adjusting the voltage and/or current provided to the first antenna module 150. When the power supplied to the consumable chip 200 is too low or too high, the power supplied to the first antenna module 150 may be directly adjusted by the power control circuit 141 to satisfy the normal operation of the consumable chip 200.

It is understood that the power control circuit 141 may be disposed independently of the first master module 120 (e.g., the structure shown in fig. 3), or may be disposed inside the first master module 120.

In this embodiment, the first main control module 120 is specifically configured to send a detection signal to the consumable chip 200 through the second antenna module 160, and adjust the voltage and/or the current provided to the first antenna module 150 through the power control circuit 141 when a feedback signal meeting a preset requirement and returned by the consumable chip 200 is not received within a preset time, so as to adjust the energy of the radio frequency power emitted by the first antenna module 150. The working principle of the detection signal is basically the same as that of the first regulating circuit, and the description thereof is omitted.

Unlike the first adjusting circuit, the second adjusting circuit adjusts the rf power of the first antenna module 150 by changing the voltage or current supplied to the first antenna module 150 to satisfy the normal operation of the consumable chip 200. The second regulating circuit can be realized by hardware or software, such as a transformer, a variable resistor, selection of each control branch, and the like.

In this embodiment, by setting the adjusting circuit, the sensing effect between the antennas can be adjusted without moving the wireless chip, for example, the voltage or the current provided to the first antenna module 150 is changed, so that the sensing effect of the wireless power supply is improved, and the stability of the wireless power supply is further improved.

In some embodiments, the read/write device 100 further comprises a third type of regulating circuit.

Fig. 4 is a schematic structural diagram of a third adjusting circuit in the embodiment of the present application, and as shown in fig. 4, the adjusting circuit includes a resonant frequency control circuit 142 for adjusting the resonant frequency provided to the first antenna module 150. When the power supplied to the consumable chip 200 is too low or too high, the resonant frequency supplied to the first antenna module 150 may be directly adjusted by the resonant frequency control circuit 142, so as to change the rf power that the first antenna module 150 can supply, so as to satisfy the normal operation of the consumable chip 200.

It is understood that the resonant frequency control circuit 142 may be disposed independently from the first main control module 120 (e.g., the structure shown in fig. 4), or may be disposed inside the first main control module 120.

In this embodiment, the first main control module 120 is specifically configured to send a detection signal to the consumable chip 200 through the second antenna module 160, and adjust the resonant frequency of the first antenna module 150 through the resonant frequency control circuit 142 when a feedback signal that meets a preset requirement and is returned by the consumable chip 200 is not received within a preset time, so as to adjust the energy of the radio frequency power emitted by the first antenna module 150. The working principle of the detection signal is basically the same as that of the first regulating circuit, and the description thereof is omitted.

Unlike the first adjusting circuit and the second adjusting circuit, the third adjusting circuit adjusts the rf power of the first antenna module 150 by changing the resonant frequency provided to the first antenna module 150 to satisfy the normal operation of the consumable chip 200. The third adjusting circuit can be implemented by hardware or software, such as a clock control circuit, a crystal oscillator, and the like.

In this embodiment, by setting the adjusting circuit, the sensing effect between the antennas can be adjusted without moving the wireless chip, for example, the resonant frequency provided to the first antenna module 150 is changed, so that the sensing effect of the wireless power supply is improved, and the stability of the wireless power supply is further improved.

It should be noted that, in the foregoing embodiments, the feedback signal received by the first main control module 120 includes voltage information for characterizing the operation provided to the consumable chip 200, and the voltage signal directly reflects whether the supply voltage of the consumable chip 200 meets the requirement, so that the first main control module 120 determines whether the electric energy provided to the first antenna module 150 needs to be adjusted. The information representing the voltage may be a voltage value, or a signal representing the voltage value, or a signal representing whether the voltage meets the requirement given by the consumable chip 200 after comparison, and the specific representation form is not limited.

In some embodiments, the read-write apparatus 100 may further include a fourth adjusting circuit, and the fourth adjusting circuit may include at least two of the antenna switching circuit, the power supply control circuit, and the resonant frequency control circuit.

Fig. 5 is a schematic structural diagram of a fourth adjusting circuit in the embodiment of the present application, and as shown in fig. 5, the adjusting circuit includes an antenna switching circuit 144, a power supply power control circuit 141, and a resonant frequency control circuit 142 at the same time, where the antenna switching circuit 144, the power supply power control circuit 141, and the resonant frequency control circuit 142 may be adjusted and controlled by the first main control module 120. The power control circuit 141 provides different voltages or currents to the resonant frequency control circuit 142, and the resonant frequency control circuit 142 generates corresponding resonant frequencies according to the different voltages or currents. The connection relationships of the three kinds of adjusting circuits of the antenna switching circuit 144, the power supply power control circuit 141, and the resonant frequency control circuit 142 are not limited to the manner shown in fig. 5, and may or may not have a control relationship with each other.

It is understood that the antenna switching circuit 144, the power supply control circuit 141 and the resonant frequency control circuit 142 may be all disposed independently from the first main control module 120 (for example, the structure shown in fig. 5), may be all disposed inside the first main control module 120, or may be partially disposed independently from the first main control module 120 and partially disposed inside the first main control module 120.

Fig. 6 is a schematic structural diagram of a consumable chip in the embodiment of the present application, and as shown in fig. 6, at a side of the consumable chip 200, the second main control module 220 includes a power conversion module 210 and a wireless communication module 230; the power conversion module 210 is electrically connected to the third antenna module 250 for obtaining power supply energy; the wireless communication module 230 is electrically connected to the power conversion module for transceiving the wireless data.

The second main control module 220 may directly convert and process the rf power captured by the third antenna module 250, or may complete the conversion and processing of the rf power through the power conversion module 210, which is only a division of a physical structure, and is integrated in a chip or divided into several modules, which is not limited herein. The modules for converting and processing radio frequency electrical energy are listed separately herein for ease of understanding.

In some embodiments, the second master control module 220 is specifically configured to receive, through the fourth antenna module 260, the wireless data sent by the read-write device 100, process the wireless data to obtain a processing result, and feed back the processing result to the read-write device 100 through the fourth antenna module 260. The wireless data may be a read command, and the processing result may be a response to the read command, that is, data stored in the consumable chip 200 is fed back to the read/write device 100; the wireless data may also be a write command, and the processing result may be feedback when the consumable chip 200 writes data correctly or incorrectly, or the like. Therefore, the read-write device 100 can know whether the consumable chip 200 correctly completes the instruction sent by the read-write device 100 at the first time according to the feedback result of the consumable chip 200.

In some embodiments, the specific structure of the power conversion module 210 in the consumable chip 200 is explained.

the voltage stabilizing circuit 212 is configured to process the direct-current voltage signal to obtain a voltage (e.g., 3V) for the consumable chip 200 to stably operate, and output a working voltage signal to other modules (e.g., the second main control module 220 and the functional circuit module are connected to each other) in the consumable chip 200.

Optionally, the rectifying circuit 211 may specifically adopt a full-wave rectification mode, and compared with half-wave rectification, power conversion efficiency may be improved.

In some embodiments, referring to fig. 7, the power conversion module 210 further includes: a voltage sampling circuit 213; the voltage sampling circuit 213 is connected to the third antenna module 250.

The voltage sampling circuit 213 is configured to sample a voltage signal induced by the third antenna module 250 to obtain a voltage sampling value, and send the voltage sampling value to the second main control module 220. The second main control module 220 feeds back the voltage information representing the voltage sampling value to the read-write device 100, specifically, the voltage information is fed back to the read-write device 100 through the fourth antenna module 260, and the read-write device 100 determines whether the voltage provided to the consumable chip 200 meets the requirement according to the feedback signal, thereby further determining whether the power provided to the first antenna module 150 needs to be adjusted.

In some embodiments, the second master module further comprises: a voltage feedback circuit (not shown in the figure); and the voltage feedback circuit feeds back a signal representing a voltage sampling value to the read-write equipment through the fourth antenna module.

In some embodiments, the voltage information sent by the consumable chip 200 to the read/write device 100 includes: a voltage sampling value obtained by sampling the radio frequency power received by the third antenna module 250, or a voltage sampling comparison result obtained by comparing the voltage sampling value with a preset voltage range. That is, the second main control module 220 may not perform a judgment operation on the received voltage, and directly send the signal representing the voltage to the read-write device 100, and the read-write device 100 judges whether the radio frequency power at this time meets the requirement, or the second main control module 220 itself has a voltage comparison function, compares the voltage sampling value with a preset voltage value, and feeds back the result after comparison to the read-write device 100.

For example, the consumable chip 200 may directly feed back the voltage sampling value to the read-write device 100, or compare the voltage sampling value with a preset voltage range and feed back the voltage sampling comparison result to the read-write device 100. For example, if the voltage sample value is within the preset voltage range, the voltage sample comparison result is determined to be 01, and if the voltage sample value is not within the preset voltage range, the voltage sample comparison result is determined to be 00, etc., and the specific numerical value or range of the voltage sample value is represented by 001, 002 … 00N. Through feeding back the voltage signal that third antenna module 250 received to reading and writing equipment 100, can let reading and writing equipment 100 in time know whether the voltage that provides consumptive material chip 200 meets the requirements, prevent that the too high voltage from damaging the power conversion module, if burn zener diode, or prevent that voltage from crossing lowly, make reading and writing equipment 100 and consumptive material chip 200 can not establish effective connection late, improve work efficiency, guarantee circuit module's stability simultaneously, improve the reliability.

In addition, the modules of the second main control module 220 for processing the wireless communication data received by the fourth antenna module 260 and processing the feedback data provided to the fourth antenna module 260 may be separately configured as independent modules, that is, the wireless communication module 230, and the wireless communication module 230 completes the wireless communication data interaction process with the read-write device 100.

In some embodiments, for the first antenna module 150 in the read-write device 100 and the third antenna module 250 in the consumable chip 200, the two antenna modules are used for performing wireless power supply, so the operating frequencies of wireless signals of the two antenna modules can be set to a lower frequency range, for example, can be set between 1 MHz and 10 MHz.

In some embodiments, for the second antenna module 160 in the read-write device 100 and the fourth antenna module 260 in the consumable chip 200, which are used for wireless communication, the specific structures and operating frequencies of the two antenna modules may be determined based on the manner in which the read-write device 100 and the wireless communication module 230 in the consumable chip 200 perform wireless communication.

Specifically, if the reader/writer device 100 and the wireless communication module 230 communicate with each other by using an RFID (Radio Frequency Identification), the two antenna modules may have a coil structure, and the operating Frequency may be set to 13.56MHZ or 125 Khz. For example, fig. 8 is a schematic diagram of a coil-type antenna in the embodiment of the present application.

In addition, if the read-write device 100 and the wireless communication module 230 use the microwave radio frequency technology, the two antenna modules may use a symmetric antenna or a microstrip antenna, and the operating frequency may be specifically set to 433Mhz, 860 to 930Mhz, or 2.4 GHz. For example, fig. 9 is a schematic diagram of a symmetric array antenna in the embodiment of the present application, and fig. 10 is a schematic diagram of a microstrip antenna in the embodiment of the present application.

Therefore, the interference resistance between the first antenna module 150 and the second antenna module 160, and between the third antenna module 250 and the fourth antenna module 260 can be improved by the design of separating frequency bands; in addition, a certain distance needs to be maintained between the antenna modules, thereby reducing interference between the antenna modules.

In some embodiments, in consumable chip 200, third antenna module 250 and fourth antenna module 260 may be integrated on the same PCB (Printed Circuit Board) at the same time; or, the fourth antenna module 260 is disposed on the PCB of the consumable chip 200, the third antenna module 250 is disposed on another PCB, and the consumable chip 200 is connected to the PCB on which the third antenna module 250 is disposed through a wire.
