基于iOS和SensorTag的数据采集系统设计

Design of Data Acquisition System Based on iOS and SensorTag

传感器数据采集是可穿戴终端设计是否实用的关键系统。本文选取集成了低功耗蓝牙和6种传感器的Sensor Tag作为终端,在i OS系统的基础上开发出能实现环境温湿度、红外温度以及方向等参数的采集系统。系统设计过程中,主要使用UIKit、Core Bluetooth等框架,重点给出低功耗蓝牙通信和传感数据计算的设计要点。测试结果表明,所采集的各项数据正确,符合设计要求。

Data acquisition system is one of critical systems for wearable terminal. In this regard, this paper presented an acquisition system based on iOS and SensorTag, which is integrated with Bluetooth 4.0 and 6 kinds of sensors. The designed system could realize the collection of environment＇s temperature and humidity, the directions, the infrared temperature and other parameters. The communication process with Bluetooth and how to calculate the sensor＇s data were focused in this study, which were the design points of the system. Tested results showed that the data collected was correct and meet the design requirements.
