Problems solved by technology

There are also difficult problems in the connection of multi-reader active RFID reader system based on RS485
RS485 communication needs to customize a special protocol, which is difficult to develop
At the same time, the communication rate of the bus is not high, and in the communication, the data is easy to conflict and get stuck, which brings hidden dangers to the system instability; the multi-reader RFID reader system based on RS232 has limited window resources of the host server, and the simultaneous access The reader is limited to a few, which limits the number of devices used, and each device needs a cable to connect to the host server, making wiring equally cumbersome, so it has not been widely used

Abstract

The invention discloses a reader system. The reader system comprises a processor, a data adapter, a power supply end power supply carrier module, a bus, a plurality of reader-writers and a plurality of lamp boxes. The processor is used for controlling the working state of the reader-writer through the bus. The data adapter is electrically connected with the bus and the processor respectively and is used for enabling the processor and the bus to carry out asynchronous communication. The power supply end power supply carrier module is used for filtering a transmission signal on the bus so as toextract a carrier signal. The bus comprises a power line and a CAN bus, the power line is used for transmitting a power signal, and the CAN bus is used for transmitting a carrier signal. The lamp boxis used for indicating the working state of the reader-writer. The invention further discloses a reader setting method. By means of the reader system and the reader setting method, multiple readers can be connected at the same time, and the working states of the readers can be rapidly displayed.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a reader system and a setting method. Background technique [0002] With the development of science and technology, active radio frequency identification is a communication technology that identifies specific targets and reads and writes related data through radio signals, and has the advantage of non-contact connection. Its application has gradually penetrated into people's daily life, such as product logistics management and tracking and other interactive services. [0003] Manufacturing systems and warehousing and logistics systems are gradually being replaced by intelligent and semi-intelligent equipment and instruments. The process of intelligent equipment is complicated, and the amount of data is huge, and the requirement for parallel use of multiple readers is becoming stronger and stronger. How to provide an efficient, stable, reliable and convenient mult...
