Chip upgrading system, transmission component and chip end

[0001] The present application claims priority to the Chinese patent application No. 202410663300.1, filed on May 24, 2024, entitled "Chip read-write system", No. 202410659568.8, filed on May 24, 2024, entitled "Chip read-write system", No. 202410757478.2, filed on June 12, 2024, entitled "Chip upgrading system, transmission component and chip end", all of which are incorporated herein by reference in their entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of chip upgrading, in particular to a chip upgrading system, a transmission component and a chip end. BACKGROUND

[0003] A printer is a commonly used office equipment. The printer has consumables such as ink cartridges and developing cartridges. The consumables are provided with chips for storing relevant information about the consumables, such as consumable model, production date, manufacturer, serial number, chip program version and other attribute information. As the consumable model is updated, the current program content in the chip needs to be overwritten and updated, which requires using a chip upgrading device to burn the chip program, that is, to perform "rework" processing on the chip to be upgraded.

[0004] Generally, the chip stores chip data, including program data and consumable-related data. The program data is required for the operation of the chip itself, like the operating system of a computer; and the consumable chip data is the configuration data read by the printer or the chip. The "rework" operation can include one or a combination of modification, addition and deletion of the chip program data or the consumable-related data.

[0005] The existing chip upgrading device (rework device) is usually provided with a device host and a test head. The test head is provided with a program burner and a coprocessor. In the state that the test head and the device host are connected to each other, after the upgrading data is downloaded from the background (remote server), the process of burning data to the chip includes the following steps: the host MCU of the rework device analyzes and processes the burning data -> the security chip decrypts and authenticates -> the coprocessor executes the read-write chip command -> the peripheral circuit (op chip + MOS tube, etc.) converts the special signals required by the chip -> the chip and other data conversion processes.

[0006] Due to the multiple conversions of data in this process, the upgrading efficiency of the entire chip upgrading system is low. SUMMARY

[0011] In a possible design, the transmission component is a straight-through component, and the chip upgrading system does not perform signal conversion during the period from when the client sends the second upgrading data signal to the transmission component to when the chip end receives the third upgrading data signal through the transmission component; the chip upgrading system not performing signal conversion includes that the second upgrading data signal and the third upgrading data signal are the same.

[0012] In a possible design, the second upgrading data signal and the third upgrading data signal are the same; including that the second upgrading data signal and the third upgrading data signal have the same effective data segment, and the effective data segment indicates that the data extracted after the second upgrading data signal and the third upgrading data signal are parsed are the same.

[0013] In a possible design, the transmission component is an upgrade device, the IC is installed on the upgrade device, the upgrade device receives the second upgrade data signal sent by the client, and outputs the third upgrade data signal to the chip end via the IC according to the communication protocol of the consumable chip.

[0014] In a possible design, the interface protocol of the chip end for receiving the third upgrade data signal is consistent with the interface protocol of the client for sending the second upgrade data signal.

[0015] In a possible design, the chip end receives the third upgrade data signal via a USB protocol, or the chip end receives the third upgrade data signal via a print authentication protocol of the consumable chip.

[0016] In a possible design, the chip end is provided with a USB interface or a flat cable interface for receiving the third upgrade data signal via a USB protocol.

[0017] In a possible design, the USB interface or the flat cable interface is arranged on the consumable cartridge and directly electrically connected to the consumable chip, or the chip end is further provided with a connecting portion, and the USB interface or the flat cable interface is electrically connected to the consumable chip via the connecting portion.

[0018] In a possible design, when the chip end is further provided with a connecting portion, the connecting portion is embedded with a signal isolation component, the connecting portion receives the third upgrade data signal via a USB protocol, and the signal isolation component converts the third upgrade data signal into a fourth upgrade data signal according to the communication protocol of the consumable chip and sends the fourth upgrade data signal to the consumable chip.

[0019] In a possible design, the connecting portion is a card clip, the card clip is installed on the consumable cartridge and has a chip interface, the USB interface or the flat cable interface is arranged on the card clip and arranged correspondingly to the chip interface, and the USB interface or the flat cable interface is electrically connected to the consumable chip via the chip interface.

During transmission of the second upgrade data signal from the client to the transmission component and transmission of the third upgrade data signal from the transmission component to the chip end, the second upgrade data signal is converted at most once. The data does not need to be processed and transferred by various modules in the transmission component. During the process, the transmission component does not process the data or processes the data only once. There is no complex transmission process of multiple data conversions such as parsing and processing of the host MCU, decryption and authentication of the secure chip, execution of read and write chip commands by the co-processor, conversion of special signals required by the chip by the peripheral circuit (op-amp chip + MOS tube, etc.), and the chip. As a result, the transmission time of the upgrade data is shortened, the upgrade data is not easy to be intercepted and deciphered, and the risk and instability are reduced.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of the present application more clear, the technical solutions in the present application will be described clearly and completely below in combination with the drawings in the present application. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0036] The chip read-write includes reading and writing chip programs, and for writing chip programs, the current program content in the chip can be covered.

[0037] The chip upgrading device in the prior art includes a device host and a test head body. Generally, the device host is a desktop operating device provided by a chip upgrading device supplier, and is connected with the test head body through a connecting line. Each set of chip upgrading device is matched with a device host, which causes cost increase. In addition, the device host is provided with circuit modules, interaction modules and the like, so that the whole chip upgrading device cannot be made small and compact, and is inconvenient to carry and use.

[0038] Since the device host is provided with circuit modules, interaction modules and the like, the analysis conversion, decryption, protocol conversion and the like of the upgrading data are generated in the data transmission path (i.e. the chip upgrading device), which causes the transmission time of the upgrading data from generation to the chip to be long, and increases the risk of burning failure and data cracking.

[0039] In the prior art, the data of the upgrading device needs to be further converted and processed locally after being downloaded from the background, and the final data is generated before being burned into the consumable chip. The type of the device hardware circuit and the performance of the processor depend on the type of the consumable chip and the complexity of the data, which determines that the device hardware is bound to have many components, and the circuit is complex, and the BOM cost is high. In addition, since the data needs to be processed and transferred by different modules in the device, the burning time is long, and the data is easy to be intercepted and cracked, which increases the risk and instability.

[0040] Therefore, the present application provides a chip upgrading system, which provides an upgradable chip. The chip is integrated with a DFU (Device Firmware Upgrade) program (upgrading module 143) for data conversion and processing during upgrading of the chip firmware. In the embodiment of the present application, the upgradable chip can directly convert and process the upgrading package, thereby reducing the upgrading data processing requirement and hardware requirement of the upgrading device.

[0041] In an embodiment of the present application, as shown in FIG. 1, a chip upgrading system is provided, which at least includes a server 11, a transmission component (an upgrading device 13 or a transmission data line or other adapter embodiment) and a chip end 14. The chip end 14 includes a consumable chip 141 installed in a consumable box. In the embodiment of the present application, the consumable chip 141 is used for identity authentication and ink recording of the consumable box at the printer end, and the chip end 14 receives the upgrading data sent by the server 11 to upgrade the data of the consumable chip.

[0042] In an embodiment of the present application, the functions of the components of the chip upgrading system are as follows:

[0043] Server 11: responsible for database management, rework-related program control, and other system functions; the server 11 is configured with rework-related programs (scripts, etc.) and other system functions (encryption, logs, background management, etc.);

[0044] Client 12: mobile phone / computer and other user terminal devices: support the installation of pre-installed APP or connection to pre-installed operation webpage, responsible for the human-machine interface, system function and rework data transfer, which is connected with the test head handle through the USB interface and uses USB protocol communication; the client 12 is configured with rework device App software or can be connected to the pre-installed operation webpage (UI interface, rework function, account management, etc.);

[0045] Transmission component: taking the upgrade device 13 as an example, the upgrade device 13 (test head handle): including a USB socket (connected with the client 12), such as a type C socket, a burning probe and a PCB; of course, the transmission component can also be other embodiments described in the application embodiments, or other components that can realize the transmission of upgrade data between the client 12 and the chip end 14, and the transmission component can be provided with a one-time conversion circuit (for one-time data conversion in the application embodiments) or not.

[0046] Chip end 14: including a printer contact and a die IC, the IC including an upgrade program, a FLASH memory and a logic circuit. If the printer contact protocol transmission is an analog signal, the chip will increase the USB burning contact, and if the printer contact protocol transmission is a digital signal, the chip burning contact and the printer contact are the same, the chip uses IIC protocol, SPI protocol and other digital protocols (print authentication protocol) when working at the front door, and uses USB protocol to communicate with the upgrade device 13 during upgrade. In the embodiments of the application, the chip front door contact and the USB contact are shared, and the chip automatically identifies whether it is USB or IIC or SPI protocol.

[0047] In the embodiment of the present application, the server 11 and the client 12 are communicatively connected by using Bluetooth, WIFI and the like, and are configured to send the first upgrade data signal to the client 12; the client 12 and the chip end 14 are communicatively connected by the transmission component, and the client 12 receives the first upgrade data signal sent by the server 11 according to the user operation; in an embodiment of the present application, the first upgrade data signal is protocol-converted on the client 12 into the second upgrade data signal of the output protocol of the client 12, such as the USB protocol, and the second upgrade data signal is sent to the transmission component; wherein the chip end 14 includes a consumable chip 141 installed in the consumable box, the consumable chip 141 is configured to authenticate the consumable box at the printer end, and the chip end 141 receives the third upgrade data signal through the transmission component to perform data upgrade of the consumable chip; in an embodiment of the present application, the protocol of the third upgrade data signal is a protocol supported by the interface of the chip end 14; wherein during the period from when the client 12 sends the second upgrade data signal to the transmission component to when the chip end 14 receives the third upgrade data signal through the transmission component, the second upgrade data signal is at most subjected to one signal conversion.

[0048] That is, in the embodiment of the present application, in the process of sending the upgrade data signal from the client 12 to the chip end 14, the upgrade data signal is at most allowed to be subjected to one data change or no data change, so as to save the propagation time of the upgrade data signal.

[0049] In the embodiment of the present application, the transmission component is at most provided with one signal isolation component, and the signal isolation component is configured to perform one processing of the signal conversion as described in the present application, such as data increase or decrease, signal delay, protocol conversion and the like, and in an embodiment of the present application, the signal isolation component is configured to perform communication protocol conversion, so as to convert the protocol of the second upgrade data signal sent by the client into the protocol of the third upgrade data signal required by the chip end.

[0050] In an embodiment of the present application, the signal isolation component is an IC (Integrated Circuit).

[0051] It should be noted that in the embodiment of the present application, resistors, capacitors and other components can also be provided in the transmission path or the transmission component as needed, and the resistors, capacitors and other components should not be regarded as the signal isolation component as described in the present application, because the signal waveform amplitude changes in the transmission process, but does not affect the judgment result of data acquisition, that is, no signal conversion is performed, and therefore in an embodiment of the present application, the transmission component is provided with other components which do not perform signal conversion in addition to the IC, and is regarded as being provided with only one isolation component.

[0052] In an embodiment of the present application, the transmission component is a straight-through component, that is, the transmission component only realizes data transmission and does not perform signal conversion, such as a data line.

[0053] When the transmission component is a pass-through component, the data received by the chip end 14 is a third upgrade data signal; the to-be-upgraded data sent by the client 12 is a second upgrade data signal, and the data of the third upgrade data signal is the same as that of the second upgrade data signal. It should be understood that the data referred to in the present application refers to the data extracted after the third upgrade data signal and the second upgrade data signal are parsed, and it should not be determined that the two data are completely the same. Here, the "same" allows the processing of waveform amplitude variation or waveform burr fluctuation or slight signal delay or advance, but the output waveform does not affect the judgment result of data acquisition.

[0054] In the present application, the third upgrade data signal and the second upgrade data signal include that the third upgrade data signal and the second upgrade data signal have the same valid data segment, and the valid data segment indicates that the data extracted after the third upgrade data signal and the second upgrade data signal are parsed is the same.

[0055] That is, when the isolation component is only used for communication protocol conversion or is a pass-through component, in the present application, the data transmission process from the server 11 to the chip end 14 is transparent, and there is no need to perform data parsing processes such as encryption and decryption. Other devices can be arranged between the server 11 and the chip end 14 as data transparent devices. Data transmission refers to transmitting data from one device to another device through a transmission medium while maintaining the integrity and accuracy of the data. The data parsed by the logic analyzer is the same. Thus, the transmission time of the upgrade data is greatly shortened, and the hardware requirements of the transmission component are reduced.

[0056] As shown in FIG. 8, an embodiment of protocol conversion data transparent transmission is given:

[0057] For example, the server 11 wants to send 128 bytes of 0x55 data to the chip end 14, and the data is transparently transmitted through the client 12 and the upgrade device 13. The following steps are required:

[0058] Step 1: The server 11 sends the chip upgrade data to the client 12 through WIFI / Bluetooth, etc.

[0059] Step 2: The client 12 fills in the header data according to the USB protocol, places the 128-byte valid data in the DATA data field, and splices the frame;

[0060] Step 3: The client 12 sends the frame data packet to the upgrade device 13 (transmission component) according to the USB protocol. After receiving the USB data packet, the upgrade device 13 parses the data packet according to the USB protocol and extracts 128 bytes of valid data 0X55;

[0061] Step4: The upgrading device 13 fills the header book according to the IIC protocol format, and then fills 128 bytes of effective data into the Data data part of the write command to splice into an IIC frame data packet;

[0062] Step5: The upgrading device 13 sends data to the chip end 14 according to the IIC protocol (write chip), and the chip end 14 parses the data packet according to the IIC format, extracts 128 bytes of effective data of DATA, and since the upgrading device 13 does not process and convert the 128 bytes of effective data, the 128 data received by the chip is the original data.

[0063] In the embodiment of the application, the server 11 is used to publish the latest version of software and data, remotely control the upgrading terminal platform software, and interact with the terminal platform, is responsible for database management, program control related to rework, and other functions of the system.

[0064] The client 12 can be a mobile phone or a tablet computer, supports installation of a preset APP or connection of a preset operation webpage. The client is used for man-machine interface display and control of chip upgrading operation. The client and the upgrading device perform wireless communication, and send instructions or upgrading data to the upgrading device. The upgrading device is connected with the upgrading device through wireless or wired mode, commonly used USB, Bluetooth or WIFI, and the USB interface is preferably used.

[0065] The upgrading device 13 includes a handle 131 and a test head 132. The test head 132 includes a probe for connecting with the chip contact 142 to transmit data. The upgrading device 13 is used to receive operation instructions sent by the server 11 or data for upgrading and resetting the chip. The operator can operate the handle 131 to align the probe on the test head 132 with the chip contact 142 to implement the upgrading operation of the chip 14. The test head 132 includes a communication interface module, an MCU control module (a primary conversion circuit), a power module and a probe. The communication interface of the chip uses the IIC / SPI / UART interface commonly used in printers, so that the chip does not need to additionally increase a burning contact, and the IIC interface is preferably used. The control module (the primary conversion circuit) of the upgrading device 13 is responsible for data transfer, transmits data sent by the mobile phone (the client 12) to the chip according to the chip front door protocol, and does not process the data in the middle. The upgrading device 13 and the mobile phone can use USB, Bluetooth or WIFI for communication.

[0066] The consumable chip 141 includes a chip contact 142 and a wafer IC, the IC including an upgrade module 143, a FLASH memory and a logic circuit. The upgrade module 143 receives an instruction sent by the client 12, including data for burning the chip 14, and after the chip 14 receives the data for burning, the chip automatically updates the data in the chip, and performs chip rework and upgrade processing without the need for the upgrade device to process the data. The protocol on the chip side includes IIC, SPI and the like (print authentication protocol), and if the protocol of the chip contact 142 is an analog signal, the chip adds an IIC burning contact, and if the protocol is a digital signal, the chip burning contact and the contact for contacting the printer are the same, and there is no need to add a burning contact.

[0067] The application can simplify the hardware circuit of the upgrade device 13, the upgrade device 13 is only responsible for data relay and contact with the chip 14, and the data generation conversion and logic processing program is executed on the chip 14 and the server 11, and the hardware in the upgrade device 13 only needs to select a single-chip microcomputer with the lowest cost and a simple peripheral circuit, so that the cost is reduced.

[0068] The working steps of the read-write system provided by the application are shown in Table 1.

[0069] Table 1

[0070] In the embodiment of the application, the upgrade device 13 is embedded with a one-time conversion circuit, the upgrade device 13 receives a second upgrade data signal sent by the server 11 (which can pass through the client 12 device such as a mobile phone, or directly connect the server 11 through a wireless module such as WIFI / Bluetooth), and sends a third upgrade data signal according to the print authentication protocol of the consumable chip 141 or the chip end 14.

[0071] In an embodiment of the application, the interface protocol of the chip end 14 for receiving the third upgrade data signal is consistent with the interface protocol of the client 12 for sending the second upgrade data signal, that is, the transmission component is a straight-through device.

[0072] As shown in FIG. 1, the application provides a chip upgrade system, in which the upgrade device 13 (transmission component) is made more simple, the chip end is integrated with a DFU program (upgrade module 143) and a USB module, so that the chip end 14 directly uses the USB protocol to transmit data; in this way, the upgrade device 13 does not need to perform protocol conversion, and the hardware circuit is simpler, and can be set as a straight-through component.

[0073] In an embodiment of the application, the chip upgrade system includes:

[0074] Server 11: responsible for database management, rework-related program control, and other system functions; the server 11 is configured with rework-related programs (scripts, etc.) and other system functions (encryption, logs, background management, etc.);

[0075] Client 12: mobile phone / computer and other user terminal devices: support the installation of a preset APP or connection to a preset operation webpage, responsible for the human-machine interface, system functions, and rework data transfer, which is connected to the test head handle through the USB interface and uses USB protocol communication; the client 12 is configured with a rework device App software or can connect to a preset operation webpage (UI interface, rework function, account management, etc.);

[0076] Upgrade device 13 (test head handle): including a USB socket (connected to the client 12), such as a type C socket, a burning probe, and a PCB;

[0077] Chip end 14: including a printer contact and a die IC, the IC including an upgrade program, a FLASH memory, and a logic circuit. If the printer contact protocol transmission is an analog signal, the chip will add a USB burning contact. If the printer contact protocol transmission is a digital signal, the chip burning contact and the printer contact are the same. The chip uses IIC and other digital protocols (print authentication) when working at the front door, and uses USB protocol to communicate with the upgrade device 13 during upgrading. In an embodiment of the present application, the chip front door contact and the USB contact are shared, and the chip automatically identifies whether it is a USB or IIC protocol.

[0078] In an embodiment of the present application, USB protocol is always used for transmission between the chip end 14 and the client 12, without the need for data conversion, improving data transmission efficiency.

[0079] In an embodiment of the present application, it can be seen that the cost of the device is concentrated in the hardware of the upgrade device 13. The structure of the upgrade device 13 is shown in FIG. 2. The upgrade device 13 only has a USB socket (not shown), a handle 131, and a test head 132, with fewer components, simpler circuit, lower cost, and faster upgrade data transmission. The test head only serves as a connection, and the data transmission control is realized by the interaction between the mobile phone and the chip.

[0080] In an embodiment of the present application, the test head 132 uses a probe to directly align the contacts of the consumable chip 141 for burning; in another embodiment of the present application, as shown in FIG. 3, the test head 132 uses a USB device end 133 to connect with the USB chip end 142 of the chip end 14.

[0081] In the embodiment of the application, when the upgrading device 13 (test head handle) is inserted into a mobile phone or computer (client 12) through a USB socket, a U disk disk symbol or a HID device is presented, and the data transmission between the client 12 and the chip end 14 can be performed as U disk reading and writing files or HID devices such as a mouse and a keyboard reading and writing data.

[0082] The upgrading device 13 (test head handle) does not contain a one-time conversion circuit and a program, and the working process of chip upgrading is only between the server 11, the client 12 (App or webpage) and the chip end 14, and the upgrading device 13 (test head handle) only plays a role of data transmission, and the upgrading process is shown in Table 2.

[0083] Table 2

[0084] In an embodiment of the application, the chip end 14 is provided with an upgrading data processing function and a USB module, can directly use a USB protocol to perform data transmission with a mobile phone and other clients 12, and the rework device 13 (test head) is only responsible for electrical connection and does not process data, so that the cost of a single-chip microcomputer is saved, the hardware cost of the rework device is greatly reduced, the test head is easier to mass produce, consistency and stability are better, and there is no need to develop a test head program, and all programs are processed in the background of the client 12 and the server 11.

[0085] In an embodiment of the application, an upgrading device 13 (test head handle) is provided, which comprises a test handle and a test head, and the test handle comprises a USB socket for connecting with a client; the upgrading device 13 (test head handle) is used in the chip upgrading system in the application.
