板式数字流量计中无线通信系统的设计

Design of wireless communication system for plate digital flowmeter

板式数字污水流量计是太原理工大学测控技术研究所自主研发的一种新型的数字流量计,针对污水排放多在环境恶劣、偏僻的地方并且采用电池供电,本文以低功耗为目的对板式流量计的无线通信系统进行了设计,包括系统硬件和软件的设计,其中着重介绍如何对NRF905进行驱动,并给出相关程序源代码。该通信系统实现了污水计量数据的无线发送与接收,设计的三种工作方式达到了降低功耗目的。

Plate digital sewage flowmeter is researched and developed independently by the Institute of Measurement and Control Technology, TYUT. Because more of sewage drainage are in the poor environment, remote areas and using battery-powered, aiming at low-power consumption, the wireless communication system of plate digital sewage flowmeter is designed. This paper presents the hardware and software design and focus on how to drive the NRF905. Some related source code is presented. The communication system achieve the wireless transmission and reception of the sewage measurement data and the three modes designed reach the purpose of low-power consumption.
