Abstract: Firstly,the requirements of production control and the features of bus assembling process are studied,the bus assembling production control system is built,and the common five-tier architecture is adopted.Then,the key technologies and development platform used in the system realization are studied in-depth.Automatic identification technology is used in data acquisition,vehicle tracking and routing control technologies are used in application server,and Web technology is used in statement analysis.Data acquisition and statement analysis implementation are separately based on the Windows and Web application of.NET platform and vehicle tracking and routing control implementation are based on the configuration software named as GE Fanuc Proficy Tracker intelligent platform.Every layer's function is distinct and integrated seamlessly in the entire system,and the whole architecture has strongly robustness and expansibility.Finally,the validity of this system is proved by an application case.
