PASSIVE OPTOELECTRONIC TAG, OPTOELECTRONIC READER-WRITER AND PASSIVE OPTOELECTRONIC IDENTIFICATION SYSTEM

摘要

Disclosed are a passive optoelectronic tag, an optoelectronic reader-writer and a passive optoelectronic identification system. The passive optoelectronic tag comprises: a photoelectric cell, a light emitter and receiver, and a control processing optoelectronic identification (OEID) chip, wherein the photoelectric cell is used to power the light emitter and receiver and the control processing OEID chip; the control processing OEID chip is used to control the light emitter and receiver to be in an emitter state or a receiver state for emitting or receiving data; and the light emitter and receiver is used to emit or receive an optical signal. The light emitter and receiver is a device integrating a light emitter and a light receiver, which solves the problem in the relevant art that an RFID tag has a large area and a high cost, thus providing a feasibility basis for reducing the tag volume, facilitating the large scale production and lowering the cost.
