2.3.3 Fast Switching Antenna to Inventory Tags
In the operation of standard inventory tags (real time mode, each antenna needs to be commanded to set the
corresponding working antenna before inventory), a single antenna inventory requires at least 200 milliseconds. Only
after the inventory is completed, the reader can respond to new commands.
However, in many practical application environments, it is unacceptable to switch the antenna after 200 milliseconds.
At this time, the function of quickly switching the antenna of the inventory tag needs to be used.
Use cmd_name_fast_switch_ant_inventory command (see R2000 module serial interface communication protocol
V4.0).
With this command, users do not need to send antenna switching commands, so it is faster and more efficient. On one
antenna, the time consumed to read one or two tags is only about 50 milliseconds. Please refer to R2000 module serial
interface communication protocol V4.0 for the specific usage of this command.
We can see the effect of fast 8-antenna inventory tag in the demo program.
Switch the demo program to the fast 8-antenna inventory interface, as shown in the figure below:
