The invention discloses a chip colophon system for an aluminum electrolysis control system. A chip edition is stored in the physical address of the chip, the message of the chip edition is transferred to an interface message processor through the CPU, the interface message processor responses the message of the chip edition into a server, a work station obtains the chip edition message from the server through an exchanger. The method of the invention is simple and rapid in recording the year, the month, the date of the edition and the edition number of the day, thereby avoiding confusion usage in treating hardware fault, changing chip, and analyzing trough condition, and further avoiding the fault handling error, the unconformity of the result and the design of analyzing trough condition; the displayed record of the added edition number has the advantages of knowing change effect, rapidly removing hardware exception, avoiding chip confusion usage, permanently recording edition number condition, responding changed information to each work station, and facilitating analysis, induction and edition of the software application effect.
