灵敏度很低，识别标签距离较近，但是误报几率较小；5 表示灵敏度很高，识别标签
距离较远，但是误报几率相对较大。从 1 到 5 共有 5 个等级，表示灵敏度逐步变强。
1. Sensitivity one-button setting: 3 is the factory setting, it means the normal

4、版本（version），这个参数表示程序的版本号，4200 表示主板类型，
201807111600 表示程序生成的日期。
4. The version is the firmware version number, 4200 is the model number of the
board, 201807111600 is the release date of the firmware.
5、顾客流量（进）（customer flows（in））, 这个参数记录自系统工作时候
