A printer consumable chip data update device based on Hall sensor

Abstract

This invention provides a printer consumable chip data update device based on a Hall sensor, which exhibits strong anti-interference capabilities during data transmission and is suitable for various environments. It uses a programming controller to control an electromagnet to send programming data, and the consumable controller controls a Hall element receiving circuit to receive the programming data. Simultaneously, a coil control circuit, under the action of the programming controller, causes the electromagnetic transmitting coil to emit high-frequency oscillating electromagnetic waves. An electromagnetic receiving coil inside the consumable cartridge receives these electromagnetic waves and transmits them to the consumable chip mounted on the cartridge. The consumable chip's internal rectifier and filter power supply circuit then powers the Hall element receiving circuit and the consumable controller. The electromagnetic receiving coil is located on the consumable cartridge, not within the consumable chip control circuit board. The two ends of the electromagnetic receiving coil contact the rectifier and filter power supply circuit via contacts, thus controlling the size of the consumable chip control circuit board and enabling the built-in power circuit setup.

Description

Technical Field

[0001] This invention relates to the field of chip data programming technology, specifically to a printer consumable chip data update device based on a Hall sensor. 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 the production process, the basic data stored in the consumable chips needs to be updated according to different models. 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 through contact points; while contactless programming achieves data transfer without direct contact between the programming device and the chip. Existing contactless programming technologies mostly rely on electromagnetic induction for data transfer. However, in daily production, the environment is sometimes complex, and data transfer failures can occur due to chaotic magnetic fields. Summary of the Invention

[0004] To address the issue of data transmission failure due to magnetic field disturbances in existing contactless programming methods that rely on electromagnetic induction for data transmission, this invention provides a printer consumable chip data update device based on a Hall sensor. This device exhibits strong anti-interference capabilities during data transmission and is suitable for various environments.

[0005] The technical solution of the present invention is as follows: a printer consumable chip data update device based on a Hall sensor, a data burning device and a data transmission structure; characterized in that it further includes: an electromagnetic receiving coil;

[0006] The data burning device includes: a burning controller, a coil control circuit, an electromagnetic transmitting coil, an electromagnet control circuit, and an electromagnet;

[0007] The programming controller stores the programming data to be programmed; the programming controller controls the electromagnet to be energized or de-energized through the coil control circuit, and transmits the programming data to the receiving unit of the consumable chip; the programming controller controls the coil control circuit to generate a periodically changing drive current, and generates periodically oscillating electromagnetic waves around the electromagnetic transmitting coil.

[0008] The data transmission structure is located in the consumable chip control circuit board and includes: a Hall element receiving circuit, a consumable controller, and a rectifier and filter power supply circuit;

[0009] The Hall element receiving circuit receives the programming data emitted by the electromagnet; after receiving the pulse signal sent by the Hall element receiving circuit, the consumable controller writes the programming data to the corresponding address of the basic data internal memory of the consumable chip, thus completing the data programming.

[0010] The electromagnetic receiving coil is disposed in the inner cavity of the consumable box. After the consumable chip is installed on the consumable box, the two ends of the electromagnetic receiving coil are connected to the rectifier and filter power supply circuit on the consumable chip. The electromagnetic receiving coil receives the electromagnetic waves emitted by the electromagnetic transmitting coil and transmits the electromagnetic waves to the rectifier and filter power supply circuit.

[0011] The rectifier and filter power supply circuit rectifies and filters the received electromagnetic waves to power the Hall element receiving circuit and the consumable controller.

[0012] Its further features are:

[0013] The data burning device also includes a power supply circuit, which supplies power to the burning controller, the coil control circuit, and the electromagnet control circuit.

[0014] In the data transmission structure, the rectifier and filter power supply circuit includes: capacitors C4~C7, rectifier diodes D1~D4 and Zener diode D5; the Hall element receiving circuit includes: Hall element Q and filter capacitor C;

[0015] One end of capacitor C is connected to the ground terminal of Hall element Q and then grounded. The other end of capacitor C is connected to the power supply terminal of Hall element Q, the negative terminal of Zener diode D5, one end of capacitor C7, and the negative terminals of rectifier diodes D3 and D4. The positive terminal of Zener diode D5, the other end of capacitor C7, and the positive terminals of rectifier diodes D1 and D2 are grounded. The positive terminal of rectifier diode D3 is connected to the negative terminal of rectifier diode D1 and one end of capacitor C6. The positive terminal of rectifier diode D4 is connected to the negative terminal of rectifier diode D2 and one end of capacitor C5. The other end of capacitor C6 is connected to one end of capacitor C4, and the other end of capacitor C4 is connected to the other end of capacitor C5. The signal output terminal and power supply terminal of Hall element Q are connected to the consumable controller.

[0016] The electromagnetic receiving coil includes a coil L2, the two ends of which are respectively connected to the two ends of the capacitor C4.

[0017] This invention provides a printer consumable chip data update device based on a Hall sensor. The programming controller controls an electromagnet to send programming data, and the consumable controller controls a Hall element receiving circuit to receive the programming data. The data transmission process has strong anti-interference capabilities, increasing the probability of successful data transmission and making it suitable for various environments. Simultaneously, under the action of the programming controller, the coil control circuit causes the electromagnetic transmitting coil to emit high-frequency oscillating electromagnetic waves. An electromagnetic receiving coil inside the consumable box receives these electromagnetic waves and transmits them to the consumable chip mounted on the consumable box. The consumable chip's internal rectifier and filter power supply circuit then powers the Hall element receiving circuit and the consumable controller. Therefore, the consumable chip can complete the data programming process without an external power supply. The electromagnetic receiving coil is located on the consumable box, not in the consumable chip control circuit board. The two ends of the electromagnetic receiving coil contact the rectifier and filter power supply circuit through contacts, controlling the size of the consumable chip control circuit board to achieve the built-in power circuit setup.

[0022] like Figure 1 As shown, the present invention includes the following technical solution: a printer consumable chip data update device based on a Hall sensor, a data burning device, a data transmission structure, and an electromagnetic receiving coil;

[0023] The data programming device includes: a programming controller, a coil control circuit, an electromagnetic transmitting coil, an electromagnet control circuit, an electromagnet and a power supply circuit; the data transmission structure is set in the consumable chip control circuit board, including: a Hall element receiving circuit, a consumable controller, and a rectifier and filter power supply circuit.

[0024] The programming controller stores the data to be programmed; an electromagnet is a device that generates electromagnetic fields when energized, possessing magnetism only when powered and losing it immediately upon de-energization; the programming controller controls the electromagnet to be energized or de-energized via a coil control circuit, transmitting the programmed data to the receiving unit of the consumable chip; the programming controller controls the coil control circuit to generate a periodically varying drive current, producing periodically oscillating electromagnetic waves around the electromagnetic transmitting coil; the power supply circuit supplies power to the programming controller, coil control circuit, and electromagnet control circuit. In practice, the programming controller is implemented using an MCU with computing capabilities, such as the STM32F4 microcontroller.

[0025] A Hall sensor is a magnetic field sensor based on the Hall effect, used to detect magnetic fields and their changes. Under normal power supply, the Hall sensor outputs a high-level signal when there is no external magnetic field, and a low-level signal when an external magnetic field is present. In this application, a Hall element receiving circuit is constructed based on the Hall sensor; the Hall element receiving circuit receives the programmed data emitted by the electromagnet; after receiving the pulse signal sent by the Hall element receiving circuit, the consumable controller writes the programmed data to the corresponding address in the basic data internal memory of the consumable chip, completing the data programming.

[0026] In practice, when the electromagnet is energized, it generates magnetism. The Hall element receiving circuit on the consumable chip receives the magnetic field strength of the electromagnet and generates a falling edge pulse signal. The consumable controller receives the falling edge pulse signal sent by the Hall element receiving circuit and records the programmed data as signal "1". Conversely, when the power is off, the electromagnet loses its magnetism, the Hall element receiving circuit on the consumable chip cannot receive the magnetic field strength of the electromagnet, and the consumable controller receives the high edge pulse signal sent by the Hall element receiving circuit and records the programmed data as signal "0".

[0027] like Figure 2 As shown, in the data transmission structure, the rectifier and filter power supply circuit includes: capacitors C4~C7, rectifier diodes D1~D4 and Zener diode D5; the Hall element receiving circuit includes: Hall element Q and filter capacitor C. In specific implementation, the Hall element Q is based on existing Hall elements, such as: SL1603, and can be implemented accordingly.

[0028] The electromagnetic emission coil circuit includes: capacitors C1~C3, and coil L1; one end of capacitor C1 is connected to one end of capacitor C2, the other end of capacitor C1 is connected to one end of capacitor C3, and the other ends of capacitor C2 and capacitor C3 are respectively connected to the two ends of coil L1; the two ends of capacitor C1 are respectively connected to the coil control circuit.

[0029] One end of capacitor C is connected to the ground terminal of Hall element Q and then grounded. The other end of capacitor C is connected to the power supply terminal of Hall element Q, the negative terminal of Zener diode D5, one end of capacitor C7, and the negative terminals of rectifier diodes D3 and D4. The positive terminal of Zener diode D5, the other end of capacitor C7, and the positive terminals of rectifier diodes D1 and D2 are grounded. The positive terminal of rectifier diode D3 is connected to the negative terminal of rectifier diode D1 and one end of capacitor C6. The positive terminal of rectifier diode D4 is connected to the negative terminal of rectifier diode D2 and one end of capacitor C5. The other end of capacitor C6 is connected to one end of capacitor C4, and the other end of capacitor C4 is connected to the other end of capacitor C5. The electromagnetic receiving coil includes coil L2, with its two ends connected to the two ends of capacitor C4 respectively. The consumable controller is implemented based on a microcontroller with computing capabilities (such as an STM32G microcontroller), and its pins are connected to the signal output terminal and power supply terminal of Hall element Q.

[0030] like Figure 4 As shown, the electromagnetic receiving coil is fixed inside the ink cartridge casing to receive electromagnetic waves emitted by the electromagnetic transmitting coil. The two ends of the coil are connected to terminals 1 and 2 of the consumable chip rectifier and filter power supply circuit, which provides the received electromagnetic waves to the consumable chip rectifier and filter power supply circuit to power the Hall element receiving circuit and the consumable controller.

[0031] like Figure 3 As shown, capacitors C4, C5, and C6 in the rectifier-filter power supply circuit serve as filters and detectors, rectifier diodes D1, D2, D3, and D4 form a full-wave rectifier circuit, capacitor C7 serves as a filter and energy storage, and Zener diode D5 stabilizes the rectified voltage within a safe range for use by the Hall element receiving circuit and the consumable controller. Figure 3 The load in the circuit includes a Hall element receiving circuit and a consumable controller. The programming controller controls the electromagnet to send oscillating electromagnetic waves via a coil control circuit. The electromagnetic receiving coil L2 receives electromagnetic waves from both directions. When terminal 1 of the electromagnetic receiving coil L2 outputs a high voltage, the electromagnetic wave charges capacitor C7 through rectifier diode D3. C7 then supplies power to the load, and the electromagnetic wave loop returns to terminal 2 of the electromagnetic receiving coil L2 through rectifier diode D2, completing the loop. When terminal 2 of the electromagnetic receiving coil L2 outputs a high voltage, the electromagnetic wave charges capacitor C7 through rectifier diode D4. C7 then supplies power to the load, and the electromagnetic wave loop returns to terminal 1 of the electromagnetic receiving coil L2 through rectifier diode D1, completing the loop.

[0032] like Figure 4As shown, the electromagnetic receiving coil is disposed in the inner cavity of the consumable cartridge. In this embodiment, the electromagnetic receiving coil L2 is installed on the side wall of the inner cavity of the cartridge. The two ends of L2 are respectively connected to contact 1 and contact 2 of the chip mounting slot. After the consumable chip is installed in the chip mounting slot, the two ends of capacitor C4 are provided with metal terminals to connect with contact 1 and contact 2. That is, after the consumable chip is installed on the consumable cartridge, the two ends of the electromagnetic receiving coil are connected to the rectifier and filter power supply circuit on the consumable chip. The electromagnetic receiving coil receives the electromagnetic waves emitted by the electromagnetic transmitting coil and transmits the electromagnetic waves to the rectifier and filter power supply circuit in the form of current. The rectifier and filter power supply circuit rectifies and filters the current to power the Hall element receiving circuit and the consumable controller. This application fixes the electromagnetic receiving coil inside the cartridge shell instead of placing it on the consumable chip. This not only eliminates the need to set up a separate battery structure for the data update of the consumable chip, but also achieves charging through wireless charging, eliminating the need to consider battery replacement, and greatly reducing the size of the consumable chip circuit board.

[0033] This invention employs a contactless programming method for programming consumable chips. It is particularly suitable for secondary programming of chips already installed on the consumable cartridge, eliminating the need to disassemble the chip and simplifying the process. This eliminates cumbersome programming steps, improves efficiency, and reduces costs. The programming device uses an electromagnet to transmit the programming data, allowing the device to complete the programming without contact with the chip, thus expanding its application scenarios. By fixing the electromagnetic receiving coil inside the cartridge casing, the size of the consumable chip's circuit board is significantly reduced. Furthermore, the invention uses rectified and filtered electromagnetic waves to power the consumable chip, eliminating the need for an external power supply for programming.
