Promising development in the light emitting diode (LED) technology has spurred the interest to adapt LED for both illumination and data transmission. This has fostered the growth of interest in visible light communication (VLC), with on-going research to utilize VLC in various applications. This paper presents a mobile-health monitoring system, where healthcare information such as biomedical signals and patient information are transmitted via the LED lighting. A small and portable receiver module is designed and developed to be attached to the mobile device, providing a seamless monitoring environment. Three different healthcare information including ECG, PPG signals and HL7 text information is transmitted simultaneously, using a single channel VLC. This allows for a more precise and accurate monitoring and diagnosis. The data packet size is carefully designed, to transmit information in a minimal packet error rate. A comprehensive monitoring application is designed and developed through the use of a tablet computer in our study. Monitoring and evaluation such as heart rate and arterial blood pressure measurement can be performed concurrently. Real-time monitoring is demonstrated through experiment, where non-hazardous transmission method can be implemented alongside a portable device for better and safer healthcare service.
发光二极管（LED）技术的蓬勃发展激发了人们将LED用于照明和数据传输的兴趣。这推动了可见光通信（VLC）的发展，目前正在进行相关研究以将VLC应用于各种领域。本文介绍了一种移动健康监测系统，其中生物医学信号和患者信息等医疗保健信息通过LED照明进行传输。设计并开发了一个小型便携式接收器模块，可连接到移动设备，提供无缝监测环境。使用单通道VLC同时传输包括心电图、光电容积脉搏波信号（PPG）和HL7文本信息在内的三种不同医疗保健信息。这使得监测和诊断更加精确和准确。精心设计了数据包大小，以在最小误包率下传输信息。在我们的研究中，通过使用平板电脑设计并开发了一个综合监测应用程序。可以同时进行心率和动脉血压测量等监测和评估。通过实验展示了实时监测，其中可以在便携式设备旁边实施无害传输方法，以提供更好、更安全的医疗服务。
