Description

Technical Field

[0001] This invention relates to the field of chip data programming technology, specifically to a wireless update device for printer consumable chip data. Background Technology

[0002] Printers are widely used electronic devices. Common printers include inkjet and laser printers, both consisting of a main unit and consumables. Printing consumables include a cartridge (commonly known as an ink cartridge) and a consumable chip. The cartridge contains toner or ink, while the chip stores basic printer data, including consumable manufacturer information, model number, color, and original and usage information.

[0003] During production and use of consumable boxes, it is necessary to update the basic data stored in the consumable chip for various reasons. This update requires a programming device to input the data into the chip. Common methods for updating basic data include contact programming and contactless programming. Contact programming involves data transfer between the programming device and the chip being updated via contact points; while contactless programming achieves data transfer without direct contact between the programming device and the chip. Existing contactless programming technologies mostly require an external power supply for the chip, which is very inconvenient. Some engineers have designed designs using built-in batteries, but battery life issues need to be considered in long-term use, further complicating its application. Summary of the Invention

[0010] The amplitude modulation circuit is used to adjust the amplitude of the data. After adjusting the amplitude of the received burning data and the power supply electromagnetic wave signal data, the data is sent to the electromagnetic wave transmitting circuit in a high-frequency manner. The electromagnetic wave transmitting circuit is responsible for sending the burning data and the power supply electromagnetic wave signal to the electromagnetic wave receiving circuit in the form of electromagnetic waves.

[0012] After being powered by the power supply circuit, the programming controller receives the programming data provided by the data processing unit, converts the waveform of the programming data into a digital signal, and writes the programming data to the corresponding address of the basic data internal memory of the consumable chip to complete the data programming.

[0013] The data processing unit rectifies and filters the waveform signal of the received burning data to provide the burning data waveform to the burning controller.

[0016] In the data transmission structure, the power supply circuit includes: diode D2, capacitor C5, and Zener diode TD1; the data processing unit includes: diode D1, resistor R1, and capacitor C2; the electromagnetic wave receiving circuit includes: inductor L2, capacitor C3, and capacitor C4.

[0017] The inductor L2 is a three-terminal inductor, including: two terminals 1 and 3, and a center tap terminal 2; terminal 1 of the inductor L2 is connected to one end of the capacitor C4, the other end of the capacitor C4 is connected to the positive terminal of the diode D2, the negative terminal of the diode D2 is connected to the negative terminal of the Zener diode TD1 and one end of the capacitor C5, the positive terminal of the Zener diode TD1, the other end of the capacitor C5, terminal 2 of the inductor L2, one end of the capacitor C3, one end of the resistor R1, and one end of the capacitor C2 are grounded; terminal 3 of the inductor L2 is connected to the other end of the capacitor C3 and the positive terminal of the diode D1; the negative terminal of the diode D1 is connected to the other end of the resistor R1 and the other end of the capacitor C2;

[0024] like Figure 1As shown, the present invention includes a wireless data update device for printer consumable chips, comprising: a data programming device and a data transmission structure; the data transmission structure is disposed in the consumable chip control circuit board, and the data programming device and the data transmission structure establish a data link through electromagnetic wave near-field communication.

[0025] The data burning device includes: a data providing unit, an amplitude modulation circuit, an electromagnetic wave transmitting circuit, and a data acquisition unit; the data transmission structure includes: an electromagnetic wave receiving circuit, a power supply circuit, a data processing unit, and a burning controller.

[0026] The data providing unit stores the electromagnetic wave signal data for power supply and the data to be programmed, and sequentially sends the electromagnetic wave signal data for power supply and the programming data to the amplitude modulation circuit. The amplitude modulation circuit adjusts the amplitude of the data, and after adjusting the amplitude of the received programming data and electromagnetic wave signal data for power supply, sends them sequentially to the electromagnetic wave transmitting circuit at high frequency. The electromagnetic wave transmitting circuit is responsible for sending the programming data and the electromagnetic wave signal for power supply to the electromagnetic wave receiving circuit in the form of electromagnetic waves. The data acquisition unit collects the amplitude-modulated programming data sent by the electromagnetic wave transmitting circuit in real time and transmits it to the data providing unit. The data providing unit receives the amplitude-modulated programming data transmitted by the data acquisition unit, analyzes it, and monitors the accuracy of the data sent by the electromagnetic wave transmitting circuit in real time.

[0027] In practice, the electromagnetic wave signal data for power supply and the programming data are created on a personal PC or similar environment using a data creation tool. Then, a dedicated export tool is used to import them into the data providing unit of the data programming device via a USB 2.0 interface, RS232 interface, or similar method. After importation, the data providing unit can sequentially send the stored electromagnetic wave signal data for power supply and the programming data to be programmed.

[0028] The data providing unit is implemented based on an existing MCU microcontroller with computing capabilities (such as the STM32F4 microcontroller). The data acquisition unit acquires the amplitude-modulated programming data emitted by the electromagnetic wave transmitting circuit and sends it to the data providing unit. Within the data providing unit, the amplitude-modulated programming data is compared with the previously stored programming data to confirm the accuracy of the data emitted by the electromagnetic wave transmitting circuit in real time, thereby ensuring that the electromagnetic wave transmitting circuit can accurately send the data to the programming controller.

[0029] The electromagnetic wave receiving circuit sends the received programming data to the data processing unit and sends the received power supply electromagnetic wave signal to the power supply circuit; the power supply circuit processes and stores the received power supply electromagnetic wave signal to supply power to the programming controller when programming data.

[0030] After being powered by the power supply circuit, the programming controller receives the programming data provided by the data processing unit, converts the waveform of the programming data into a digital signal, and writes the programming data to the corresponding address in the basic data internal memory of the consumable chip, thus completing the data programming.

[0031] The data processing unit rectifies and filters the waveform signal of the received programming data to provide the programming controller with the programming data waveform.

[0032] like Figure 2 As shown, in the data transmission structure, the power supply circuit includes: diode D2, capacitor C5, and Zener diode TD1; the data processing unit includes: diode D1, resistor R1, and capacitor C2; the electromagnetic wave receiving circuit includes: inductor L2, capacitor C3, and capacitor C4.

[0033] Inductor L2 is a three-terminal inductor, including: two terminals 1 and 3, and a center tap terminal 2; terminal 1 of inductor L2 is connected to one end of capacitor C4, the other end of capacitor C4 is connected to the positive terminal of diode D2, the negative terminal of diode D2 is connected to the negative terminal of Zener diode TD1 and one end of capacitor C5, the positive terminal of Zener diode TD1, the other end of capacitor C5, terminal 2 of inductor L2, one end of capacitor C3, one end of resistor R1, and one end of capacitor C2 are grounded; terminal 3 of inductor L2 is connected to the other end of capacitor C3 and the positive terminal of diode D1; the negative terminal of diode D1 is connected to the other end of resistor R1 and the other end of capacitor C2.

[0034] The programming controller is implemented based on a microcontroller with computing capabilities (such as the STM32G microcontroller) in the existing technology. Its control pins are connected to capacitor C2, the negative terminal of Zener diode TD1, the negative terminal of diode D2, and one end of capacitor C5, respectively.

[0035] Because the electromagnetic wave signal data for power supply pre-stored in the data providing unit and the electromagnetic wave direction of the programmed data are opposite. After the data providing unit first sends out the electromagnetic wave signal data for power supply, the electromagnetic wave transmitting circuit, including capacitor C1 and inductor L1, sends the electromagnetic wave signal data for power supply to inductor L2 through inductor L1. After receiving the electromagnetic wave signal data for power supply, inductor L2... Figure 3 As shown (the arrows in the figure indicate the direction of current), the current is fed into the power supply circuit through terminal 1 of L2 and capacitor C4. In the power supply circuit, diode D2 acts as a rectifier, capacitor C5 acts as an energy storage and filter, and Zener diode TD1 stabilizes the voltage within the operating voltage range of the microcontroller. When capacitor C5 is charged, capacitor C5 supplies power to the programming controller.

[0036] After the data providing unit sends out the electromagnetic wave signal data for power supply, it continues to send the programming data, such as... Figure 4As shown in the diagram (arrows indicate data flow), the programming data is sent to the data processing unit via endpoint 3 of L2. In the data processing unit, diode D1 acts as a rectifier, and resistor R1 and capacitor C2 form a detector circuit to filter out interference in the received data. Then, the programming data is transmitted to the programming controller. The programming controller writes the basic data, including consumable manufacturer information, model, color, and original and usage information of the consumable, into the corresponding storage address in the consumable chip according to the preset address.
