则我们就可以规避掉报警记录中，第 3 到第 8 条情况下的误报。
Then the false alarm of alarm data No. 1 to 8 will stop.
主板会随时采集检测范围内的无线信号，并对当前采集到的信号的特性进行分析，
符合标签特征的信号则进行报警。报警数据日志，就是主板每次识别出标签（报警）
的特性的综合数据记录。信号必须最终同时符合三个特性（peak、snr，peak pos
max-peak pos min）的判断条件，才会被认为是标签信号。以下是三个特性的判断
条件：
The main board will collect the RF signal in the range of detection at any time,
and analyze the characteristics of the signal collected at present, and give the alarm to
the signal that conforms to the feature of the tag. The alarm data log is the
comprehensive data record that the main board recognizes the characteristics of the
label (alarm) every time. In order to be considered as a tag signal, the signal must
ultimately meet the criteria of three characteristics (peak, snr, peak pos max - peak pos
min). The following are the criteria for judging the three characteristics:
Peak：

信号的 peak 数值（如图 6-3 所示），必须在 range_1 或者 range_2 范围内。
