11、报警次数（alarm count），该参数表示从主板上电起至当前的总计报警次

数，断电后清零。

11. The alarm count is total alarms quantity that counted from the system power

on of the last time. When the power off, the number is resume to 0.

12、峰值门限（peak gated）, 低位（low）默认值是 150，高位（high）默认

是 2047。设置范围是 0-2047。峰值门限参数的数值范围是区间表达，有 2 个有效

区间（range_1 和 range_2）。系统采集到的信号特征（峰值）数值，只要在其中任

一区间范围内，则被认为是标签信号。峰值低位（low）是报警最重要的参数之一，

参数越小，报警的概率越高，反之报警的概率越低。在不误报的情况下，可以通过减

小该参数来提高天线识别标签的距离。

12．The peak gated low value is set at 150 and high value is set at 2047 by factory.

The setting range is 0-2047. The range of peak gated is 2 effective intervals (range_1

and range_2). The characteristic (peak) value of the signal collected by the system is

regarded as the label signal as long as it is in any range. The low peak is one of the

most important parameters of alarm. The smaller the parameters, the higher the

probability of alarm, otherwise the lower the probability of alarm. If there is no false

alarm, the detection distance can be wider by reducing this parameter.

13、信噪比门限（snr gated），低位（low）默认值是 3，设置范围是 0-255，

高位（high）默认是 255。信噪比门限参数的数值范围是区间表达，有 2 个有效区间

（range_1 和 range_2）。系统采集到的信号特征（信噪比门限）数值，只要在其中

任一区间范围内，则被认为是标签信号。信噪比低位（low）是报警最重要的参数之

一，参数越小，报警的概率越高，反之报警的概率越低。在不误报的情况下，可以通

过减小该参数来提高天线识别标签的距离。

13. The signal to noise ratio (snr gated), the low bit (low) default value is 3, the

setting range is 0-255, and the high (high) default is 255. The numerical range of snr

is expressed by interval. The parameters are 2 effective intervals (range_1 and range_2).

The signal characteristics (signal-to-noise ratio threshold) values collected by the

system are considered as label signals as long as they are in any range. Low signal-to-

noise ratio (low) is one of the most important alarm parameters. The smaller the

parameters, the higher the alarm probability, otherwise the lower the alarm probability.

The smaller the parameters, the higher the alarm probability, otherwise the lower the

alarm probability. If there is no false alarm, reduce this parameter, the detection

distance will be wider.
