Chip version switching method, device and system

Abstract

The invention provides a chip version switching method, device and system. The switching method comprises that after that a flag bit of version information is accessed, whether the flag bit is vacant is determined; if it is determined that the flag bit is not vacant, version information in chip data is replaced according to the flag bit; after that a first part address bit of the chip data is accessed, a flag in the flag bit is modified into a version setting flag, or the version setting flag is written in the flag bit; and whether a second part address bit of the chip data is accessed is determined, and if it is determined that the second part address bit of the chip data is accessed, the version setting flag in the flag bit is erased. According to the chip version switching method, device and system, the chip version information can match the version information of imaging equipment by accessing the address bit in the chip data, the chip is suitable for different versions of imaging equipment, and the upgrade resistance is high.

Description

technical field [0001] The invention relates to the communication field, in particular to a version switching method of a consumable chip, a version switching device of a consumable chip, and a version switching system of a consumable chip. Background technique [0002] Current imaging equipment such as printers, copiers, fax machines, and multi-functional ones usually include lasers and inkjet types. Consumable containers such as powder / ink cartridges applied to imaging devices usually need to be installed with a chip. After the imaging device communicates with the chip normally, the imaging device can normally use the consumables in the consumable container. For example, the consumables can be ink or toner. [0003] The chip can be used to store the communication data required for communication between the imaging device and the chip, realize the communication protocol and communication method between the imaging device and the chip, etc. The chip can also be used to store...

AI Technical Summary

Problems solved by technology

After the firmware of some imaging devices is upgraded, the number of times the imaging device accesses the chip will also change, which will cause the chip that could be used to be unusable due to the firmware upgrade.

Therefore, the existing method may lead to the fact that the chip is originally suitable for the corresponding version of the imaging device, and the ability to resist firmware upgrades is poor.
