The Design And Research Of Parachute Guidance System

In the21st century, with the rapid development of economy and the progress of scienceand technology，the troops put forward higher requirements for the quality and safety of theparachute training. However, the training and equipment of the armed forces can not meet theneeds of the parachute training,which directly lowers the parachute training quality andtherefore safety incidents have occurred occasionally.This thesis is to design a parachutingboot system for parachute training based on the above formulate questions. Combining actualconditions of skydiving, this subject has developed creative solutions to the problems above,that is using voice activated intercom and Air pressure sensor to measure height.Macro-design was optimized to provide technical support for the solutions.The parachuting boot system shall, on the basis of functions, be classified into thewireless intercom module, parachuting height measurement module and parachute automaticalarm module. This paper describes briefly the principle of voice activated intercom made upof speech recognition chips LD3320and HKT-80BK intercom module、the principle of Airpressure sensor BMP085and the principle of parachute automatic alarm, Then it introducesmajor performances of the primary MCU STC10L08X and STC89C51.The hardware andsoftware for the parachuting boot system were designed in details in this project.The parachute boot system prototype has been produced According to the requirementsand the methodologies of design, the prototype’s various performances all meet the designrequirements when experimentally tested. The parachute boot system has significant militaryand economic benefits, which can effectively solve various difficulties in parachute troopstraining and significantly improve the quality of training.
