一、引言实现测量数据的自动采集是建立在计量检定/校准自动化系统的基础上。无线数据采集方式较有线方式而言,具有更好的便利性和灵活性。目前主流的近距无线通信技术,如蓝牙、Wi Fi、Zig Bee等,都存在射频干扰和射频泄漏的问题。若用于高准确度、高灵敏度的计量测试仪器的数据采集传输,将对测量结果的准确性产生不利影响。同时,也将给系统的信息安全带来隐患。由于可见光通信(VLC)既不受射频干扰又不会 I. INTRODUCTION The automatic collection of measurement data is based on the metrological verification / calibration automation system. Wireless data acquisition method than the wired way, with better convenience and flexibility. At present, the mainstream short-range wireless communication technologies, such as Bluetooth, Wi-Fi and Zig Bee, have the problems of radio frequency interference and radio frequency leakage. If used for data acquisition and transmission of high-accuracy and high-sensitivity metrology instruments, the accuracy of measurement results will be adversely affected. At the same time, it will also bring hidden dangers to the information security of the system. Because visible light communication (VLC) is neither radio frequency interference nor will it
