Problems solved by technology

[0004] There are two main types of electronic interpreters currently on the market: one is the electronic interpreter used in large outdoor places, and the technology used is mainly GPS, such as Pinyou electronic tour guides, which are expensive and cannot be used in museums. The other type is the tourism management electronic interpreter, its function is mainly to assist the tour guide in some auxiliary management, such as counting the number of people, explaining in the team, and cannot realize the "automatic" function

Description

technical field [0001] The invention belongs to the technical field of communication, relates to a self-service voice system, in particular to a self-service voice system based on RFID and data redirection technology. Background technique [0002] RFID (Radio Frequency Identification) technology, also known as radio frequency identification technology, is a 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] Data redirection technology is a data processing technology based on the file system. The purpose of data redirection is to change the direction of data flow, so that the data flow bypasses certain devices as required, and then directly sends data processing technology to the target device, which can improve data transmission efficiency and save device resources. [0004] There are two main type...
