Abstract :
An infrared based test matching system hardware platform used for group psychoanalysis purpose is introduced in the paper. The platform is composed with more than 30 infrared transmit parts and one receive end, with a Microchip MCU as their processors. An innovative coding and decoding scheme is designed in this system, which shortens the IR code length and the wave circle period comparing to normal IR coding modes. The computer program finishes the final data processing. This device effectively reduces the infrared signal conflicts and improves the assess productivities greatly, and the optimized anti-noise program make it possible for a group´s Q and A (Questioning and Answering) or voting purpose.
