Two-out-of-two system applied to transponder transmission module

The invention relates to a two-out-of-two system applied to a transponder transmission module, which is characterized by comprising an A channel input data source, a B channel input data source, an A channel module and a B channel module, an A comparison input end (IN), an A comparison output end (OUT), a serial connection of a channel A1 and a channel A2 and an A comparison success output end are arranged in the A channel module; a B comparison input end (IN), a B comparison output end (OUT), series connection of a channel B1 and a channel B2 and a B comparison success output end exist in the B channel module; according to the method, two channels are completely independently verified and jointly confirmed, so that data errors caused by inconsistent cache numbers before communication are eliminated, and security protection for consistent data processing and communication is added in a hardware state confirmation and software communication mode. And the receiving and outputting consistency of the data in the
