Noise diagnosis method, signal control method, diagnosis device and radioactive level measuring equipment

The invention relates to a method for signal diagnosis of a radioactive measurement sensor, in particular for noise detection, comprising: detecting a first pulse occurrence rate by means of a first discriminator (D1) and a first counting unit (Z1); detecting at least a second pulse incidence by means of a second discriminator (D2) and a second counting unit (Z2), the amplitude sensitivity of the first discriminator (D1) being different from the amplitude sensitivity of the second discriminator (D2); determining a ratio between the pulse occurrence rate detected by the second discriminator (D2) and the pulse occurrence rate detected by the first discriminator (D1); and comparing the determined ratio to an expected value. 本发明涉及用于放射性测量传感器的信号诊断的方法，特别是用于噪声检测的方法，该方法包括：通过第一鉴别器(D1)和第一计数单元(Z1)检测第一脉冲发生率；通过第二鉴别器(D2)和第二计数单元(Z2)至少检测第二脉冲发生率，其中，第一鉴别器(D1)的振幅灵敏度不同于第二鉴别器(D2)的振幅灵敏度；确定第二鉴别器(D2)所检测的脉冲发生率与第一鉴别器(D1)所检测的脉冲发生率之间的比值；以及将所确定的比值与预期值进行比较。
