Multi-channel Temperature Acquisition and Processing
System based on Micro Control Unit
Abstract: This topic designs a multi-channel temperature acquisition processing system based on micro control unit. By comparing different implementation scheme and thorough reasoning, chooses the best solution. This design takes AT89C51 MCU system as the core, and DS18b20 temperature sensor as temperature acquisition device, combined with the temperature acquisition module, keyboard module, display module, alarm module, serial communication module and so on to complete the 4-way temperature signal acquisition and display on the display devise. This design mainly uses C language to write programs, and keil software to write and debug the software. In terms of hardware this design adopts Proteus to finish the hardware circuit debugging and simulation.
Key words: AT89C51; DS18b20; Alarm; Serial Communication; LED
