Abstract
The proposed eight way responder of the curriculum design,
with the development of science and technology, a variety of means
to urge people to learn science, learning technology, learning
knowledge diversity. The contest has been widely applied in all kinds
of intelligence and knowledge competitions occasions. The design is
based on the eight road as the basic concept, mainly uses the
microcontroller as the core device, the use of single-chip timer /
counter timing and counting principle, the soft and hard organic
combination, so that the system can complete the design time are
correct, at the same time adopts digital display direct instructions,
automatic latch display results. And design idea of automatic reset,
switching to do with the keyboard output using speaker voice
prompts, the design has the characteristics of simple structure, fast
response, the system of powerful functions, good reliability, simple
operation and strong practicability. To achieve an accurate and fair
level. With intuitive judgment of the %rst responder signi%cance.
