The invention discloses a method of improving the blacklist matching efficiency of terminal equipment of an AFC (Automatic Frequency Control) system. The method comprises the following steps: (1) designing a memory and downloading scheme of a blacklist of station terminal equipment; (2) recording the hash function design and an address conflict solution determination of a ticket-card logic number statistical law based on single black list; (3) defining two operating modes including an off-line mode and an online mode by a blacklist retrieval mode and an algorithm design, and designing all authorized operations based on an order chain table and a hash table. The method provided by the invention can be used for the ticket-card list detection of the AFC system of urban mass transit, and is capable of promoting the retrieval speed of the ticket-card blacklist through software upgrading under the precondition that terminal hardware is constant; furthermore, blacklist data in a terminal memory can be manually increased and deleted through an online operating mode in an emergency condition, so as to realize the real-time response on the blacklist data change by the terminal equipment.
