摘要
随着计算机技术的高速发展,单片机在仪器测试领域的应用越来越广泛。本文设计的温度检测系统采用AT89C51单片机作为控制中心,利用温度传感器AD590将温度转换成电信号,通过模/数转换芯片AD574完成A/D转换,同时用移位寄存器74LS1648进行串行输入/并行输出实现温度的显示。测试结果表明,该系统电路简单,工作稳定可靠。
A temperature detection system based on AT89C51 is designed in the alarm system as the wide applications of MCU in instrumentation fields. That conversion from Temperature to electric signals is realized by temperature sensor AD590,and A/D is completed by AD574 and temperature display implemented by shift register 74LS164. Test results show that the system works stable and reliable with simple circuit.
