The Design And Implementation Of Measurement & Control System For Helicopter Training Simulator

With the development of simulation technology,simulation training has been widely used in many industries.The helicopter simulation training has become an important part of the helicopter training,its status is also more and more important.Air machinist on the one hand,is responsible for the maintenance of helicopters and air flight security organization work,on the other hand,is in charge of helicopter engine start-up and shutdown in flight and manipulation of the related equipment and dispose of emergency work.And simulation training with high efficiency low cost,convenient maintenance and training,will be improve helicopter mechanic troubleshooting ability and disposal ability the important means.The helicopter training simulator is an integrated system,measurement & control system is the important part of it.Measurement & control system is mainly to collect simulation cabin equipment status according to the command of PC and driving cockpit related equipment work.This paper illustrates the design scheme of measurement & control system,the circuit principle of measurement & control board,and also introduces the measurement & control board core application software design process and design idea and design method of measurement and control software.Design of measurement & control system adopts modular structure,both testability,maintainability design at the same time,contains two independent parts: measurement & control board and measurement & control computer,The structure of the system is composed of upper machine and lower machine.Design of measurement & control system is a distributed system,through 3 serial port server will be 28 connected to the measurement and control of computer measurement and control board.To ST company STM32F103 microcontroller as the core design universal measurement & control board,to Keil ?Vision4 of ARM as a development platform for software design,realized the real time data collection and the drive control of the equipment.Measurement & control computer based on LabWindows/CVI software development platform design,implementation of lower machine data,master commands parsing and data transmission.Measurement & control board by RS485 interface,measurement & control system adopts the UDP communication protocol,communication with high efficiency,fast response time measurement & control system.Design of measurement & control board can complete switch and analog data and testing as well as to the table lamp,motor drive control,digital tube and other equipment.Design method is simple and easy to implement,is of high popularization value.Functional testing,measurement & control system after the system test and simulator run stability,high reliability,meet the requirements of the use of simulation training.
