Detailed Description
In the related art, an inert gas monitor of a high temperature gas cooled reactor nuclear power plant 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 equipment debugging period, whether the alarm function of the monitor can be normally realized needs to be verified, the verification method is shown in figure 1, a radioactive source with preset intensity is placed into a radioactive 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 give an alarm in response to the analog quantity signal, and conversely, when the monitor can give no alarm in response to the analog quantity signal, the alarm function can be determined to be abnormal. Although the method can verify whether the alarm function of the monitor can be normally realized, the personnel can be seriously damaged by irradiation, and the output of the radioactive source is unstable, so that the radioactive source cannot necessarily reach the alarm value of the monitor, and the verification result has deviation.
In order to solve the technical problem, embodiments of the present application provide a method and an apparatus for checking an alarm function, and a radioactive source monitor, which utilize a pulse signal to replace a detection signal to check an alarm function, so as to solve the problem of inaccurate checking caused by unstable output of a radioactive source in the existing checking method, and simultaneously avoid the risk of damage to a worker due to radioactive irradiation caused by using the radioactive source. In addition, during debugging, as the radioactive source is not needed for alarm calibration, the complex operation processes of transportation, storage, use and the like of the radioactive source can be greatly reduced, thereby shortening the debugging period.
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below with reference to the accompanying drawings in combination with the detailed description. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present application. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present application.
It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In the description of the present application, it is 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.

The alarm function verification method, the alarm function verification device and the radiation source monitor provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
As shown in fig. 2, a first embodiment of the present application relates to an alarm function verification method for verifying an alarm function of a radiation source monitor, the verification method including:
and step S110, generating a pulse signal with a 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 radioactive source monitor does not use a radioactive source for alarm debugging, the pulse signal generator is utilized to generate the pulse signal, and the pulse signal replaces a detection signal to carry out subsequent debugging procedures, so that whether the alarm function of the inert gas monitor is normal or not 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 debugging of the radioactive source through the pulse signal and can be applied to an environmental field without the radioactive source, thereby greatly reducing the complicated operation processes of transportation, storage, use and the like of the radioactive source and shortening the debugging period.
In order to accelerate 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 alarm value is set to be '2' corresponding to the lowest frequency of the detected signal, the signal lower than the frequency cannot trigger the alarm unit to alarm, and in the debugging process, if the signal with the frequency of '2' cannot trigger the alarm unit to alarm, the alarm function of the alarm unit can be considered to be invalid, so that the frequency of the pulse signal is selected, and whether the alarm function is valid or not can be accelerated. Optionally, before the acquiring the pulse signal with the preset frequency, the method further includes:
and acquiring an alarm value of an alarm unit, and determining the preset frequency of the pulse signal according to the alarm value.

and amplifying the acquired pulse signal with the preset frequency.
And step S130, determining the effectiveness of the alarm function according to whether the analog quantity signal triggers an alarm unit to alarm.
In order to determine whether the alarm values of the alarm units are in fact or not, the alarm values of the alarm units can be adjusted during the commissioning process. For example, under the condition that the analog quantity signal is not changed, the alarm value of the alarm unit is increased, the alarm value is increased, correspondingly, the analog quantity signal can not meet the triggering condition any more, and in the debugging process, if the alarm is still existed or not cancelled after the alarm value of the alarm unit is increased, the alarm value of the alarm unit can be determined to be inconsistent with the actual alarm value; on the contrary, the alarm value of the alarm unit can be reduced, the alarm value is reduced, correspondingly, the analog quantity signal inevitably meets 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 determined not to be in accordance with the actual alarm value or the alarm function of the alarm unit is determined to be invalid. Optionally, the determining the effectiveness of the alarm function according to whether the analog quantity signal triggers an alarm unit to alarm includes:
determining whether the analog quantity signal triggers an alarm unit to alarm or not;
if yes, increasing the alarm value of the alarm unit, and determining whether the alarm is cancelled after the alarm value is increased;
and if so, determining that the alarm function is effective.
According to the steps, the alarm function calibration method of the embodiment of the application utilizes the pulse signal to replace the detection signal to perform alarm function calibration, can solve the problem of inaccurate calibration caused by unstable output of the radioactive source in the existing calibration method, and can avoid the risk of damage to workers due to radioactive irradiation caused by the use of the radioactive source.
