But Qiangda is used for lower frequency, and some production plex, or low reliability. As a unit, if specifically to buy a responder although the economy can bear, each year the number is extremely small, often because of the longterm storage ( electronic devices) responder damage, to the purchase of the trouble and the timeliness of activities will be affected, so the design of the responder. This design is eight way contest as the basic concept. Considering the timelimited answer according to need to set the function, using AT89C51 MCU and peripheral interface of the answering system, the use of singlechip timer / counter timing and counting principle, the soft and hardware bination, so that the system can correctly time, while the digital tube able to correctly display the time. Switching with the keyboard output, speakers in tips. At the same time the system can realize: the answer, only after the start of the answer is effective, if at the beginning of answer answer answer before the time limit is invalid。 question and answer time in 199s set。 can display which is effective and ineffective players answer answer keys, right after the music cue。 answer time and answer questions for inverted timing display, full system timing automatic reset and host a forced reset。 key lock, in effective state key invalid, illegal.
