| As a very classical experiment in modern physics experiments,the Geiger Miller counter(G-M counter)experiment is offered in major universities across the country.However,due to the limitations of experimental equipment,there are many shortcomings in this experiment,such as: the experimental content is relatively simple,the experimental operation is relatively cumbersome,experimental errors are large,and nuclear radiation safety issues.In order to solve the problems and drawbacks existing in the current G-M counter experiment,this article uses wireless communication technology,embedded technology,and a combination of software and hardware to improve the G-M counter experimental device,designed a G-M counter experimental device that can be remotely controlled,and expanded the experimental content on the basis of the new device.The G-M counter experimental device designed in this article can be remotely controlled using wireless networks.The experimental data generated in the experiment will also be sent to the host computer software through the network,without the need to come to the laboratory for experiments.At the same time,the accuracy of experimental data collection has also been greatly improved.To complete this design,this article first analyzes the current experimental device,identifies existing problems,and finds solutions one by one.Then,it designs hardware and software.The hardware design includes the mechanical structure design and the circuit design of each module.The mechanical structure design includes the design of the lead box part and the design of the detector platform.Each module includes the main control module,the booster module Signal processing module and wireless module.The software design part includes the lower computer program design and the upper computer program design.The lower computer program design includes the main control module program design and wireless module program design.The main control module program design includes the main program design,serial port subroutine design,and PWM output subroutine design.The host computer program includes the server communication program,data visualization program,and interface design for each experimental step.After completing the construction of the entire experimental platform,the system was tested on a real machine and the experimental data were analyzed,completing the verification of the entire experimental device.In summary,this article has implemented and verified the hardware and software design of the device,and completed the improvement of the G-M counter experiment. |
