经过一年的努力本人设计了一个多点温度记录读出装置,如果每秒记录一点,可以连续记录9个小时以上。多点自动温度记录读出仪使用AT89C51单片机作为主控制芯片,性能可靠。经过Proteus仿真后,已经制成的实际电路性能优秀,具有先进性和实用性。整个系统的主要电路包括:温度采样电路、24C256记录芯片、单片机控制电路、LCD读出电路。
After a year of hard work I designed a multi-point temperature recording and reading device, if you record a little bit per second, you can continuously record more than 9 hours. Multi-point automatic temperature recorder using AT89C51 microcontroller as the main control chip, reliable performance. After Proteus simulation, the actual circuit has been made of excellent performance, advanced and practical. The main system of the entire circuit include: temperature sampling circuit, 24C256 recording chip, microcontroller control circuit, LCD readout circuit.
