摘要
提出了基于PIC单片机、带隙温度传感器、CAN总线通信、传感器远距离供电、缓启型开关电源等技术的新型温度传感器设计思路,分析了温度传感器设计原理,提供软件设计流程图,最终形成即可接入现有监控系统的通用型温度传感器,又可实现自成总线分布式温度实时监测系统的新型温度传感器。
This article proposed a new temperature sensor design idea based on PIC MCU, band -gap temperature sensor, CAN bus communication, remote sensor supply, slow start switching power supply and other technologies, and analyzed its design principle and provided software design flow chart. A universal temperature sensor which can access to current monitor system was implemented, it can also be used as a new - type temperature sensor for self - sustaining bus distributed real time temperature detection system.
