摘要:

针对某些工业现场布线困难和分布分散等问题,设计了一种基于WIA-PA技术以高性能、低功耗的16位微控制器MSP430F5438A为核心的无线温度变送器。搭建了热电偶测温电路,对热电偶进行冷端补偿,设计无线模块和温度采集模块的通信程序,并对温度采集进行测试。测试结果表明,该无线温度变送器通信稳定可靠,且测量精度能保持在5‰以内。

关键词: WIA PA, MSP430, 无线温度变送器, 热电偶

Abstract:

Aiming at difficult wiring and scattered distribution in some industrial fields,this paper briefly introduces the WIA-PA technology,and designs a wireless temperature transducer based on WIA-PA with the high performance and low power consumption 16-bit MCU MSP430F5438A as the core.Thermocouple temperature measurement circuit is built for compensation of the thermocouple at the cold terminal.The designs of communication program between wireless and temperature acquisition module are given.Tests on temperature acquisition prove that the wireless temperature transducer can communicate stably and reliably with a measuring precision within 5‰.

Key words: WIA PA;MSP430;wireless temperature transducer;thermocouple
