The Research On-Line Test System On The Line Of Automobile Generator Of Windows

The technology of production line in enterprise is an important factor which deeply influence on the efficiency of product,the e scale of product and competition of the company.In order to improve its competition,the midsize enterprises have to make a reform on the present low-efficiency technology of production line.The on-line testing system on the production line can not only reduce the human cost and improve the produce efficiency,but improve on earth improve the competition of enterprise in the keen competition market.The article has been research a new on-line testing plan used on the electrical machinery on the windows of car,combined the research project form NingBo Hengte Automobile Parts co.Ltd.The work of this paper demonstrates in the following sections:How to choose a better way of communication bus in the on-line testing system is a key factor,the article compare some common way,such as RS-232 bus,CAN bus and RS-485 bus.And then decide to use the RS-485 bus in the WINDOWS to resolve the transmission problems between the pc and sub-test beds in the production line,the way isIn the process of transforming electrical level,Accomplished to choose components,to design the hard related circuit and PCB,to weld components,and to test the software and hardware of the circuit.In the design the third test bed,completed design the whole machinery structure and way of test the noise of machine vibration,including choose the sensors,design workholding device,design the shift-mechanism of vibration sensor and design the circuit of changing sampling signature and the control system.To completed the whole software by the Visual C++ and SQL,which are based on the windows operating system.And also the software will process collected data from tests.Its has friendly graphic user interface,flexible operating manner and powerful data processing function.The research of the on-line test of the components and parts of car line combine the technology of electromechanical and the technology of computer test.To transform the present product line by the economical test system,it is feasible and meaning no matter in the economic or in the technology.
