2.6 特殊误报屏蔽
2.6 Special False Alarms Shielding Methods
在现场，很多时候系统偶尔的误报并非是受到了覆盖标签频率的全范围干扰，而
是某个频段的干扰。在这个时候，我们就可以通过观察报警数据日志，找出特殊误报
的范围，设置参数规避掉一部分的特殊误报。
In the working site, the occasional false alarm of the system is not caused by the
full range interference of the label frequency, but by the interference of a certain
frequency band. In this case, we can observe the alarm data log, find out the scope of
special false alarms, set parameters to avoid this special false alarms.

点击 按钮，即可进行报警数据日志实时读取。假设当前无标签进入，
则我们看到的报警数据应均为误报报警数据（如图 6-1 所示）。
由报警数据日志可以看出，误报的 peak 范围基本上集中在 750-900 之间。则，
我们可以设置 peak gated 数据为（如图 6-2 所示）：
Click the button to make the alarm data log read in real time. Assuming
that there is no tag enter, the alarm data are false alarm data(Figure6-1).
From the alarm data, we can see that the peak range of false alarms is basically
concentrated between 750-900. Then, we can set peak gated data to(Figure6-2):
