Petrochemical enterprise toxic and harmful site speech warning method based on RFID technology

Abstract

The invention relates to a petrochemical enterprise toxic and harmful site speech warning method based on an RFID technology. The problem that a safety warning sign in the prior art is easy to be damaged, is difficultly replaced and has poor recognition is solved. According to the petrochemical enterprise toxic and harmful site speech warning method based on the RFID technology, an RFID electronic tag is arranged at a toxic and harmful site; the internal chip of the RFID electronic tag is pre-written into the unique code of the toxic and harmful site; a worker carries a handheld terminal to come into the toxic and harmful site, wherein the handheld terminal is composed of an RFID reader and a warning speech information base; the RFID reader reads the unique code of the RFID electronic tag; and warning speech information corresponding to the unique code in the warning speech information base is called according to the code. The handheld terminal is used to broadcast the warning speech information in real time, and the problem is solved. The method can be used for speech warning at the toxic and harmful site of a petrochemical enterprise.

Description

technical field [0001] The invention relates to a voice warning method for toxic and harmful places of petrochemical enterprises based on RFID technology. Background technique [0002] Radio Frequency Identification (RFID, Radio Frequency Identification) is a wireless communication technology that can identify specific targets and read and write related data through radio signals without establishing mechanical or optical contact between the identification system and specific targets. [0003] Conceptually speaking, RFID is similar to barcode scanning. For barcode technology, it attaches the encoded barcode to the target and uses a dedicated scanning reader to use optical signals to transmit information from the bar magnetically to the scanning. RFID uses a dedicated RFID reader and a special RFID tag that can be attached to the target, and uses a frequency signal to transmit information from the RFID tag to the RFID reader. Unlike barcodes, RFID tags do not need to be in l...
