Abstract: This paper mainly discusses the hardware and software design content of interlocked train control integrated system. The software part of the system is developed by VC++6.0, including four functional modules, which are route selection, route locking, signal opening and route unlocking, which can realize the integrated control of signal equipment in the station and the range, and process route commands and control ground equipment. The hardware part of the system includes STM32 main control chip, PCI driver acquisition board, and CAN communication interface. On the basis of ensuring communication speed and communication quality, the information sharing and reliable interaction between the upper computer and the lower computer are realized. Based on the data collection and analysis of rail transit signals, the system provides help for monitoring train operation and ensuring driving safety.
Keywords: rail transit signal; interlocking train control integration; route locking; PCI driving board; communication interface
現階段多數鐵路干線的車站與區間采用2套控制系統,即車站聯鎖系統和區間列控系統。這種控制模式不僅存在信號傳輸延時,而且容易出現接口故障或不兼容等問題,導致2套系統之間的信息共享能力不強,對車站區間管理造成了負面影響。軌道交通信號聯鎖列控一體化系統則是取消聯鎖和列控系統之間的接口,在每個車站均設置一套一體化系統,提高了本站左右區間及本站與臨站之間的信息共享能力,在提升車站區間管理效率以及保證列車運行安全等方面發揮了重要作用。
