Detailed Description
In the related art, the inert gas monitor of the high temperature gas cooled reactor nuclear power station process radiation monitoring and radioactive effluent monitoring system is particularly used for continuously measuring the gamma/beta ray activity concentration of inert gas in a radioactive gas sample. In the device debugging period, whether the alarm function of the monitor can be normally realized is required to be verified, the verification method is as shown in fig. 1, a radiation source with preset intensity is placed into a radiation source detector, a detection signal is obtained, the detection signal is processed by a processing unit to obtain an analog quantity signal, when the alarm function is normal, the monitor can respond to the analog quantity signal to alarm, and conversely, when the monitor can respond to the analog quantity signal without alarm, the alarm function can be determined to be abnormal.

In the description of the present application, it should be noted that the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In addition, the technical features described below in the different embodiments of the present application may be combined with each other as long as they do not collide with each other.
The method, the device and the radioactive source monitor for verifying the alarm function provided by the embodiment of the application are described in detail through specific embodiments and application scenes thereof with reference to the accompanying drawings.
As shown in fig. 2, a first embodiment of the present application relates to an alarm function verification method, which is used for verifying an alarm function of a radiation source monitor, and the verification method includes:
step S110, generating a pulse signal with preset frequency, wherein the preset frequency is determined according to an alarm value of an alarm unit.
Specifically, the pulse signal is generated and output by the pulse signal generator, and under the condition that the radiation source monitor does not use the radiation source for alarm debugging, the pulse signal generator is used for generating the pulse signal, and the pulse signal is used for replacing the detection signal for carrying out subsequent debugging programs, so that whether the alarm function of the inert gas monitor is normal can be effectively verified by the verification method. In the method, the detector of the monitor does not need to detect the radioactive source sample, thereby avoiding the use of a high-intensity radioactive source, overcoming the difficulty of unstable output of the radioactive source and avoiding radioactive damage to a great extent. Meanwhile, the method simulates the radioactive source debugging through the pulse signals, and can be applied to an environment field without the radioactive source, so that complicated operation flows of transportation, storage, use and the like of the radioactive source can be greatly reduced, and the debugging period is shortened.
In order to increase the debugging speed, the frequency of the pulse signal can be determined according to the alarm value of the alarm unit, for example, the alarm value of the alarm unit is set to be 1, the lowest frequency of the signal which can be detected by the alarm value is set to be 2, and the signal which is lower than the lowest frequency can not trigger the alarm unit to alarm, and in the debugging process, if the signal which is 2 can not trigger the alarm unit to alarm, the alarm function of the alarm unit can be considered invalid, so that the frequency of the pulse signal is selected, thereby being beneficial to accelerating the verification of whether the alarm function is valid. Optionally, before the acquiring the pulse signal with the preset frequency, the method further includes:
and acquiring an alarm value of the alarm unit, and determining the preset frequency of the pulse signal according to the alarm value.
Step S120, processing the obtained pulse signal with the preset frequency to generate an analog signal.
In order to enhance the signal and improve the detection accuracy, the pulse signal can be enhanced by filtering, amplifying and the like. Optionally, before the processing the acquired pulse signal with the preset frequency, the method further includes:
amplifying the obtained pulse signal with the preset frequency.
And step S130, whether the alarm unit is triggered to alarm according to the analog quantity signal so as to determine the effectiveness of an alarm function.
In order to determine whether the alarm value of the alarm unit corresponds to the actual value, the alarm value of the alarm unit may be adjusted during the debugging process. For example, under the condition that the analog quantity signal is unchanged, increasing the alarm value of the alarm unit, and increasing the alarm value, wherein the corresponding analog quantity signal can not meet the triggering condition any more, and in the debugging process, if the alarm value of the alarm unit is increased and the alarm still exists or is not cancelled, determining that the alarm value of the alarm unit is inconsistent with the actual alarm value; in contrast, the alarm value of the alarm unit can be reduced, the alarm value is reduced, the corresponding analog quantity signal can necessarily meet the triggering condition, and in the debugging process, if the alarm is not triggered after the alarm value of the alarm unit is reduced, the alarm value of the alarm unit is inconsistent with the actual alarm value or the alarm function of the alarm unit is invalid. Optionally, the determining the validity of the alarm function according to whether the analog quantity signal triggers the alarm unit to alarm includes:
determining whether the analog quantity signal triggers an alarm unit to alarm;
if yes, increasing the alarm value of the alarm unit, and determining whether the alarm is canceled after the alarm value is increased;
if yes, the alarm function is determined to be effective.
According to the steps, the alarm function verification method of the embodiment of the application utilizes the pulse signal to replace the detection signal to carry out alarm function verification, so that the problem of inaccurate verification caused by unstable output of the radioactive source in the existing verification method can be solved, and meanwhile, the risk that workers are damaged by radioactive irradiation caused by using the radioactive source can be avoided. In addition, during debugging, because the radioactive source is not required to be used for alarm calibration, complicated operation flows such as transportation, storage and use of the radioactive source can be greatly reduced, and thus the debugging period is shortened.
