| With the continuous development of nuclear technology,it has been widely used in nuclear power generation,industry,agriculture,medicine and other fields.At the same time,nuclear safety has always been a topic of concern,and in order to improve the emergency response capability after a nuclear accident,more new and efficient nuclear radiation monitoring equipment needs to be developed.Aiming at the insufficient real-time monitoring ability of the drop radiation detector,the low monitoring efficiency of the radiation dose rate and the wide monitoring range,and the dependence on manual on-site operation is easy to cause harm to the physical body of personnel,the drop radiation detector is in-depth research.This paper conducts in-depth research on the overall design of the throwing radiation detector,the design of the throwing device module,and the design of the preferred and radiation detector module,and the main research contents are as follows:(1)According to the demand for throwing radiation detector,taking the industrial design method as the guiding ideology and combining the quality function development method,the actual demand analysis of the throwing radiation detector is carried out,the corresponding design elements are mapped,and the importance analysis is carried out.Finally,the overall design scheme of the throwing radiation detector is constructed,and the interrelationship between each module and the specific content of each module are determined.(2)Aiming at the problem of multi-scheme comprehensive evaluation of throwing device modules,based on the comprehensive evaluation decision theory,combined empowerment and grey correlation analysis are used to carry out the comprehensive evaluation of throwing device modules.The evaluation system of the throwing device module is constructed,the subjective weight value is calculated by the fuzzy analytic hierarchy method,and the objective weight value is calculated based on the entropy value method,the gray correlation coefficient calculated by the combination weighting of the two weight values and the gray correlation analysis is weighted,the gray comprehensive correlation degree value of each scheme is solved and ranked,and finally the optimal throwing device scheme is obtained through the comprehensive evaluation of examples.(3)In view of the remote real-time monitoring requirements of the radiation detector module,based on Keil u Vision5 and Altium Designer and other software,the circuit design and development of the radiation detector sub-module are carried out,and the CZT sub-module,main control sub-module,wireless transmission sub-module and power sub-module are integrated into a complete radiation detector to realize regional real-time monitoring of environmental radiation under unattended conditions.(4)Based on the above research,the throwing radiation detector is designed,and the physical models of the throwing device module and the radiation detector module are obtained through 3D printing and PCB welding,and finally the feasibility of the throwing radiation detector is verified by actual testing.In summary,the overall design of the throwing radiation detector is carried out,three radiation detector throwing schemes are constructed,and the comprehensive evaluation decision is used to select the scheme,the circuit of the radiation detector module is designed through the circuit design software,and finally the physical model is tested to verify the effectiveness of the throwing radiation detector. |
