摘要
工业无线网络WIA-PA中现场设备采用电池供电,为保证仪表设备的正常工作和数据传送的安全可靠,势必得实时监测供电电池电量消耗情况。本文给出了通过D S 2 7 8 0测量电池电量的软件和硬件接口,实际应用表明该方法简单有效,该方案为单片机应用系统的串行扩展提供了一种行之有效的参考方案,它还可以方便地移植到其它系统中。
Field devices are battery powered in WIA-PA.Real-time monitoring of power consumption is necessary in order to ensure the normal operation of instrumentation and data transfer safe and secure.In this paper,the software and hardware interface of battery measurement by DS2780 is given,and the application shows that the method is simple and effective.The program provides an effective reference for the microcontroller serial extension,and it can be easily transplanted to other systems.
