In competitions, cultural and entertainment activities, the responder can accurately, fairly and intuitively judge the responder, and its application range is very wide, so it is necessary to design the responder. This project mainly expounds a kind of responder with AT89S52 single chip microcomputer as the core device and modular layout design, which indicates the first responder through the display of digital tube. This project uses the internal timer overflow of single chip microcomputer to generate interrupt to realize timing. The software adopts assembly and C language programming, keil software debugging and proteus software simulation. Finally, the successfully debugged program is written into AT89S52 single chip microcomputer and powered on. When the responder works normally, it can indicate the first responder and give an alarm for illegal operation. The responder designed in this project can complete the design well.

Task, but I don't think this design has the value of popularization and application, because the hardware circuit cost of this design is relatively high, and the cost performance of the designed project is not very high, which is not suitable for popularization.

In the competition, cultural and recreational activities (scare and answer activities), competition

The responder can diagnose the responder accurately, fairly and intuitively, which has a wide application prospect, so it is very necessary to design a contest. The project

This paper mainly expounds the design of modular layout and a grab point with AT89S52 single chip microcomputer as the core device.

Device, through the digital tube display indicates the first vies. This project uses the timer interrupt inside the single chip microcomputer to realize the timing overflow. Software programming, debugging and proteus software simulation are carried out by assembly and keil software in C language. Finally, after successful debugging, the program written by AT89S52 single chip microcomputer is burned and powered on. When the responder works normally, it can indicate the victim of the first responder and give an alarm to the illegal operation. This project

The design competition device can complete the design task well,

But I don't think this kind of design is worth popularizing, because the hardware circuit cost of this kind of design is high and the design project price is not very high, which is not suitable for popularization.
