The action mechanism of the stun gun is analyzed in detail and the scheme design of the stun gun system is completed. With the SolidWorks software, three-dimensional model of the system has been constructed. The characteristics of the interior ballistics of the proposed scheme of stun gun are analyzed and the corresponding interior ballistics model is proposed. The numerical computation of the interior ballistics is also conducted. According to the functions of the electrical module ,the circuit is designed and the security and reliability of the system is analyzed. At last, the test scheme of the system is proposed and some experiments are carried out which validate the feasibility of the designed system.
