多通道数字化测温系统的改进设计

Improving Design of Multichannel Digital Temperature Detecting System

目的:改进多点测温系统应用中存在的布线繁琐、数据存储交错、抗干扰性差等问题。方法:在软件中采用动态地址码设计与自动排序算法,在硬件上增加看门狗芯片,避免程序"跑飞"的情况。结果:通过高低温试验,验证了改进方法的正确性和可靠性。结论:改进后的多点测温系统布线方式灵活,数据存储正确,测温结果准确,反映及时,实现了全数字化测温及无人值守,大大提高了工作效率。

Objective To solve problems existing in muhichannel digital temperature detecting system, including boring wiring, unreliable data storage, poor anti-jamming. Methods Dynamic address code design and automatic compositor algorithms were integrated into the software design, while the running out was eliminated by adopting watch dog chip. Results The validity of the improvement were proved by high ＆ low temperature tests. Conclusion The improved system, with convenient wiring, reliable data storage, accurate results and short response time, can he applied to fully digital ＆ unattended temperature detection.
