Method and equipment for acquiring peripheral electronic tag information

The invention provides a method and equipment for acquiring peripheral electronic tag information. The equipment comprises a processor and a programmable logic device, and the programmable logic device is connected with peripheral through a single bus and connected with the processor through double buses. When the programmable logic device analyzes that the processor needs to read the electronic tag information of the peripheral, the programmable logic device sends an electronic tag information request through a single bus connected with the peripheral. After receiving a request for reading the electronic tag information of the peripheral, the peripheral returns the stored electronic tag information to the programmable logic device through the single bus connected with the programmable logic device. A receiving the electronic tag information, the programmable logic device converts the electronic tag information into information conforming to a dual-bus protocol according to the dual-bus protocol followed by t
