Abstract


With the rapid development of the railway system and the global traffic development process moves forward , computer hardware maintenance of the railway is very necessary. FC (Field Controller) is connected to monitoring equipment along the railway , and its management and control of the programmable hardware . Railway station between FC maintained computer system ( Railway Station FC maintenance system ) , which greatly facilitates the maintenance of the monitoring equipment along the railway line . This paper studies the railway station FC maintenance system \The system not only to be able to control datagram sent to the underlying FC , ??FC control , but also to provide a convenience to the user -friendly interface , but also solve part of the interface ( operation module ) and the underlying control part ( transmission module ) synchronization and communication issues . The system using Microsoft Visual Basic and Microsoft Visual C operating module and transmission module , and through message response mode to solve the synchronization problem . Message response model is based on the Windows message mechanism . The system also through shared memory mechanism to solve the problem of data transfer operation and send modules . FC datagram sent by UDP and DHCP protocols to achieve . The late test work has shown that the system meets the needs of users , and users affirmed .
