| Earthquakes and other natural disasters have occurred frequently over the years,especially in the 2008 Wenchuan earthquake,which caused huge casualties and economic losses.Because of the complicated environment,the ruins are everywhere,and there may be occasional aftershocks,epidemics,etc.,which make the post-disaster relief work,especially for the detection and rescue of life,very difficult.In addition,the positioning and disposal of terrorists concealed in buildings is also a very difficult problem in the fight against terrorism.In this thesis,according to the characteristics of the human body can launch an infrared light source,infrared tracking no car design and verification,in order to aid after disasters,counter-terrorism operations and other related products in the field of development and application to provide technical reference and reference.In this thesis,the design of the infrared tracking unmanned vehicle was carried out according to the functional performance requirements of the system,including the steering mechanism,driving mechanism,walking mechanism,etc.The key components and structural parts of the institution were designed,selected and strength checked.In the control system part,control process and composition of control system are defined.The speed measuring module,motor drive module,power module,the infrared detection module,real time image transmission module and so on were designed and selected;the research of GPS communication and the software on upper computer were carried out.Finally,we tested the design results of unmanned car,and verified the rationality and effectiveness of the design.The infrared tracking unmanned car’s design is reasonable,safe,high reliability,and long life.In the process of using,the infrared signal can be detected and tracked.Real-time image monitoring and a good human-computer interaction function can be achieved according to the control requirements.The car will be a qualified survey equipment. |
