技术领域technical field
本申请涉及通信领域，特别涉及一种可见光通信识别系统及方法。The present application relates to the communication field, and in particular to a visible light communication identification system and method.
背景技术Background technique
RFID(射频识别，Radio Frequency Identification)技术作为一项先进的自动识别和数据采集技术，已成功应用到很多领域，如：日常生活中的门禁卡、公交卡和部分餐卡等。As an advanced automatic identification and data acquisition technology, RFID (Radio Frequency Identification) technology has been successfully applied to many fields, such as access control cards, bus cards and some meal cards in daily life.
但是，利用RFID技术的识别系统由于通过电磁信号识别特定目标并读写相关数据，因此会受到其他无线电设备的干扰，影响识别性能。另外，由于电磁信号会向四面八方传播，且穿透性强，因此携带有利用RFID技术的识别系统识别到的数据信息的电磁信号易被窃取，导致数据信息在识别过程中泄露，保密性差。However, because the identification system using RFID technology identifies specific targets and reads and writes relevant data through electromagnetic signals, it will be interfered by other radio devices, which will affect the identification performance. In addition, because the electromagnetic signal will spread in all directions and has strong penetrability, the electromagnetic signal carrying the data information identified by the identification system using RFID technology is easy to be stolen, resulting in the leakage of the data information during the identification process and poor confidentiality.
