Abstract This paper introduces a microprocessor controlled intelligent Responder, the Responder Responder can
overcome the common defects. Details of their hardware and software design methods. Designed a microcontroller
AT89C51 as the core of four Responder, both from the hardware and software described in detail Responder design
approach, combined with the simulation results Proteus software, according to the circuit diagram welding kind,
software simulation and hardware debugging results show that the Responder is designed to achieve the desired
objectives.
