Intelligent chip and information processing method thereof

Abstract

The invention discloses an intelligent chip and its information processing method, wherein the intelligent chip contains MCU and signal processing circuit, wherein the MCU concludes memory unit to communicate with imaging device through signal processing circuit; the memory unit contains first capacitance memory area to store a group of non-updated non-zero capacitance data, second capacitance memory area to reserve the capacitance data updated by imaging device, marking position to control the imaging device to read the data of first and second capacitance memory areas. The information processing method of intelligent chip comprises the following steps: judging whether the order pattern from imaging device is reading order or writing order; transmitting data according to the condition of marking position if the order pattern is reading order; changing the condition of marking position according to the content of order if the order pattern is writing order. The invention can control data reading of memory area through marking position with two capacitances, which makes the intelligent chip be used repeatedly.

Description

technical field [0001] The invention relates to an intelligent chip, in particular to an intelligent chip applied in the field of imaging devices. Background technique [0002] Printers and copiers are widely used imaging devices. Popular printers or copiers generally use toner or ink as imaging consumables. Smart chip, when the box body is installed in an imaging device such as a printer or copier, the smart chip can realize information exchange with the main body of the printer or copier. Taking the toner cartridge as an example, its smart chip generally stores fixed information such as production date, manufacturer, and device code, and also stores variable data such as toner consumption and number of printed pages that need to be updated in a timely manner. Toner consumption The amount of carbon consumption is detected by the remaining amount detection device, and the carbon consumption data is generally stored in the capacity area of ​​the smart chip. As for the remai...

Problems solved by technology

[0004] While providing users with more usage information, smart chips also limit the recycling and reuse of toner cartridges or ink cartridges

For example, if the smart chip of the toner cartridge or ink cartridge is written with the data of "depletion", it means that the toner or ink contained in the corresponding toner cartridge or ink cartridge has been used up, and the printer will no longer recognize this toner cartridge. Toner cartridge or ink cartridge, even if the toner cartridge or ink cartridge is recycled and filled with new toner or ink, the printer will still refuse to recognize the toner that has been filled with consumables and repaired according to the "exhausted" information recorded in the chip cartridge or cartridge

Faced with this situation, ordinary users who recycle toner cartridges or ink cartridges generally discard expensive smart chips and buy new smart chips, which not only causes waste, but also increases the cost of recycling; of course, carbon Recyclers of powder or ink cartridges can also look for chip reset or rewriting tools to update the data in the capacity area of ​​the smart chip, that is, to eliminate the "exhausted" information, so that the smart chip can be recognized and used by the printer again, but these resets Or rewriting tools are generally expensive, and the use method is very professional, and it is not easy for ordinary users to obtain and operate
