Abstract
The utility model relates to a radiation detector with a fault detecting function, which comprises a detecting module, a central processing device and a result output device; wherein, the central processing device comprises a module that can set a threshold constant and a processing module that can make a comparison between a measurement value obtained from the detecting module and the set threshold constant; the central processing device is communicated with the detecting module and the result output device by a circuit. The radiation detector with the fault detecting function can continuously detect whether the radiation detector has faults in real time, can avoid negative results caused by the fact that the radiation detector can not veritably judge the radiation situation of an object to be detected or an area to be tested when the radiation detector has faults. The radiation detector with the fault detecting function has simple structure and is very easy to be promoted.
Description
Technical field
The utility model relates to a kind of radiac of tape jam measuring ability.
Background technology
Measure radioactive instrument usually because a variety of causes breaks down, do not have at present to detect equipment or the method whether this quasi-instrument exists fault in real time.The most dangerous situation is: when going detection whether to have radioactivity with radio-activity testing/detection/monitoring instrument, instrument because of faults itself to already present radioactive ray detect less than, and have ray to exist but instrument indication " no ray ", and may be because the deviation of testing result causes various bad consequences.
The utility model content
Technical problem to be solved in the utility model provides a kind of radiac of tape jam measuring ability, this detecting instrument can be in real time, fast, convenient, detect radiac and whether break down.
The technical scheme in the invention for solving the above technical problem is: the radiac of tape jam measuring ability, comprise detection module, central processing unit and output unit as a result, the processing module that but described central processing unit comprises the setting threshold constants block and measured value that detection module is recorded and preset threshold constant compare, described central processing unit by circuit and detection module and as a result output unit connect.
Radiac comprises radio-activity testing/detection/monitoring instrument etc., because nature exists the radioactivity background, the radio-activity testing/detection/monitoring instrument of operate as normal can be measured natural radioactivity background.If dosage/dose rate (dose equivalent/dose equivalent rate) background that radio-activity testing/detection/monitoring instrument records within a certain period of time continuously illustrates then that well below the value of nature radioactivity background this apparatus measures does not have the radioactivity background thereby has fault.But the data module setting threshold constant of the tape jam measuring ability of this programme, whether this threshold value constant can detect the standard that nature radioactivity background exists according to radiac is set, the measured value and the threshold value constant that compare detection module by processing module, if the measured value of detection module is less than the preset threshold constant, judge that then there is fault in radiac, otherwise radiac is normal.This result of determination is given the tester by output unit as a result with information feedback; Output unit can produce sound alarm signal (for example having fault just to send caution sound), light alarm signal (for example having fault to glimmer with regard to pilot lamp) or literal alarm signal or figure alarm signal or send multiple modes such as alarm signal by electric signal to the device that is connected with this radiac as a result, central processing unit can be the mimic channel with above-mentioned functions, or digital integrated circuit, or equipment such as robot calculator constitutes.
The detection module of the radiac of described tape jam measuring ability comprises probe, whether has radioactivity or the strong and weak value of radioactive size in the radiac energy article that test probe contacts of this tape jam measuring ability or the probe region.
But whether the threshold value constant that described setting threshold constants block sets can detect the standard that nature radioactivity background exists according to radiac set.
When described output unit as a result detects less than nature radioactivity background at the radiac of tape jam measuring ability, produce sound alarm signal or light alarm signal or literal alarm signal or figure alarm signal or send alarm signal to the device that is connected with this radiac by electric signal.
The several times measured value that radiac is recorded in setting-up time continuously compares with the preset threshold constant respectively, if the continuous measured value for several times of radiac is all less than the preset threshold constant, judge that then instrument breaks down, otherwise radiac is normal.The statistical error that this scheme can avoid the single detection to bring impacts testing result.
To sum up, the beneficial effects of the utility model are: whether the radiac of tape jam measuring ability of the present utility model can exist fault to detect to radiac continuously in real time, can avoid to judge the adverse consequences that article to be measured or regional radioactivity situation to be tested cause really owing to radiac breaks down afterwards to continue to use, the utility model is simple in structure, is very easy to promote.

Embodiment
With reference to shown in Figure 1, the radiac of tape jam measuring ability of the present utility model comprises detection module, central processing unit and output unit as a result, detection module can detection of radioactive detecting instrument article that test probe contacts or the region in radioactive values, the processing module that but described central processing unit comprises the setting threshold constants block and measured value that detection module is recorded and preset threshold constant compare, described central processing unit by circuit and detection module and as a result output unit connect.The several times measured value that radiac is recorded in setting-up time continuously compares with the preset threshold constant respectively, if radiac continuously several times measured value all less than the preset threshold constant, judge that then instrument breaks down, otherwise radiac is normal.This result of determination is given the tester by output unit as a result with information feedback; Output unit can produce sound alarm signal (for example having fault just to send caution sound), light alarm signal (for example having fault to glimmer with regard to pilot lamp) or literal alarm signal or figure alarm signal or send multiple modes such as alarm signal by electric signal to the device that is connected with this radiac as a result, central processing unit can be the mimic channel with above-mentioned functions, or digital integrated circuit, or equipment such as robot calculator constitutes.
