PB串口通信在航空物流中的应用

PB serial communication in aviation logistics

针对航空物流的应用需求,提出了基于RFID读卡器和数据库的数据采集处理系统。利用ActiveX通信控件,可以解决RFID读卡器与PowerBuilder之间的通信问题,成功实现串口通信,同时给出PB串口通信程序的主要代码。经多次实验表明,该系统通信可靠、稳定,满足设计的功能要求,同时拓展了PowerBuilder的应用范围。

According to the aviation application, the paper provides a RFID reader and database-based data acquisition and processing system . ActiveX communication control can solve the problem of cornmunicaton between the RFID reader and PowerBuilder,and successfully achieved the target. The paper gives the main code of PowerBuilder serial communication program. Several experiments show that the system is reliable,stabile and functional to meet the design requirements, while expanding the range of applications in PowerBuilder.
