Data Upgrading Method, Electronic Device, and Storage Medium of the Chip Rewriting Device

Technical Realization Elements:

To address the shortcomings of the prior art, the objective of the present invention is to provide a data upgrading method for a printing consumable chip rewriting device, which enables flexible updating and upgrading of data in the chip rewriting device.

The invention provides a data upgrading method for a chip rewriting device, comprising the following steps:

1. Power-on Initialization: The chip rewriting device is powered on, and the storage space and expansion interface of the device are initialized. The file in the storage space is then mounted to the file system of the chip rewriting device.
2. Connection Detection: The upper computer is connected to detect whether it is connected to the expansion interface.
3. Data Parsing: The chip rewriting device parses the data packet from the expansion interface.
4. State Judgment: The monitoring chip rewrites the device state and determines whether the chip rewriting device's state allows for a data upgrade.
5. Upgrade Judgment: The method checks whether there is an upgrade file in the file system of the chip rewriting device.
6. File Decryption: The upgrade file is retrieved and decrypted to obtain the upgrade data.
7. Data Update: The upgrade data is then transferred to the chip rewriting device via a programming interface.

Additionally, the storage space includes both an internal storage medium and an external expanded storage medium, such as an SD card, TF card, USB flash drive, or mobile hard disk.

The expansion interface is typically a USB interface.

The power-on initialization step specifically involves initializing an SD card, mounting the SD card to the chip rewriting device's file system, initializing the USB, and enumerating the USB as a Mass Storage device.

The state determination step involves determining whether the upper computer has received all files. If the file reception is not complete, the process waits for the completion of the reception; if the upper computer connection is lost, it waits for reconnection before continuing.

Before the data update step, a data verification process is included. If the upgrade data passes the verification, the process proceeds to the data update; if it fails, an error message is returned.

The step of decrypting the upgrade file uses the AES algorithm, and the data verification step uses the CRC check.

An electronic device is described, comprising: a processor; a memory; and a program stored in the memory, configured to be executed by the processor. The program includes a data upgrading method for executing the chip rewriting device.

A computer-readable storage medium is also provided, on which a computer program is stored, the program being executed by a processor to perform the data upgrading method for the chip rewriting device.

Compared to the Prior Art, the Beneficial Effects of the Present Invention Are:

The present invention provides a flexible data upgrading method for a chip rewriting device, including steps such as power-on initialization, host connection detection, data parsing, state determination, upgrade judgment, file decryption, and data update. The invention also relates to an electronic device and a storage medium configured to execute this method. The method separates the program and data in the chip rewriting device, allowing for separate upgrading and updating of the program and data via a programming interface. The data upgrading method is flexible, cost-effective, and reduces the complexity of upgrades. At the same time, the method is simple to operate and enables the flexible updating and upgrading of the chip rewriting device.

The above description is only a high-level overview of the technical solutions of the present invention. The specific technical means can be better understood through the detailed implementation described in the following examples and with reference to the accompanying drawings.

Detailed Description

The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, if there are no conflicts, the embodiments described below may be arbitrarily combined to form new embodiments.

As shown in Figure 1, the data upgrading method for the chip rewriting device includes the following steps:

1. Power-on Initialization: The chip rewriting device is powered on, initializing the storage space and expansion interface, and mounting the file in the storage space to the file system.
2. Connection Detection: The method checks whether the upper computer is connected to the expansion interface.
3. Data Parsing: The chip rewriting device parses the data packet using the USB protocol stack.
4. State Judgment: The device checks whether the chip state allows for data upgrades.
5. Upgrade Judgment: The system checks whether an upgrade file exists in the file system, specifically in the root directory.
6. File Decryption: The upgrade file is decrypted to retrieve upgrade data.
7. Data Update: The upgrade data is transferred to the chip rewriting device via the programming interface.

In an embodiment, as shown in Figure 2, the storage space includes both an internal storage medium and an external expanded storage medium, such as an SD card or USB drive. The expansion interface is typically a USB interface. The power-on initialization step involves checking the SD card and ensuring it is properly mounted to the chip rewriting device's file system. If the SD card is not detected, the process waits for it to load.
