Research And Simulated Implementation Of Qos Handoff Mechanisms Based On GA With ABC Supported

Recent years,the stepless transmission(CVT)is tremendous development in the passenger car,especially in North America,Japan and China market,the C VT transmission on the vehicle matching proportion of substantial increase year by year!About the structure principle of CVT transmission and new technologies,such as hydraulic control and the control strategy of research and achievements in domestic has long been in the press,are common,but about the calibration test of CVT transmission and performance evaluation,are seldom reported,I almost can't retrieve at present domestic enterprises and research institutes of the calibration method is mainly manual calibration,so the research and development auto stepless transmission on-line calibration and measurement and control system is of great significance.In this paper,the main research object is the roth from shenyang auto stepless transmission co.,LTD production of pure mechanical electronic stepless transmission(EMCVT).The current manual calibration experiment cycle is long,need to the scene of circuit,laboratory equipment,miscellaneous.Auto stepless transmission of mass production.So in this paper,according to the field experiment conditions,developed for early EMCVT calibration measurement and calibration system used in the experiment.It can quickly complete the calibration of a transmission box.And can display real-time data gathering and transmission of the operation.According to the principle of the mechanical structure and variable speed EMCVT,measurement and control system is to control speed motor,clutch motor and gear motor.Calibration of the task is to establish the physical contact sensor and detection monitoring object and three motor real-time status and control parameters.According to the control system of EMCVT and field experiments,this paper for the research object the EMCVT,field experiment,the control system to do a thorough research of EMCVT,established the mathematical model of clutch and shifting mechanism.USB2817 is studied in the use of the data acquisition card parameter Settings,and so on.Secondly this paper developed the system based on LabVIEW software and USB2817 dc motor control procedures,the data acquisition card based on LabVIEW is written in auto stepless transmission calibration procedures of data collection.Through the experiment,proved the correctness of the program.The last,I writed friendly man-machine interactive interface,convenient,clearly display the current calibration status.And run the program with experiments to prove the feasibility of this system.
