| Abstract: | The security of Rail Transit Signalling Systems directly influenced whether trains could run safely,reliably and efficiently.In order to ensure the security of signalling systems,it was necessary to have a special security design for safety computer in signalling equipments.It was deeply studied the safety computer based on Power QUIIC processor in Rail Transit Signalling Systems.On the basis of that,a multi-module prototype of safety computer based on PowerQUICC II was designed and implemented,and its functions was tested.It was provided a good foundation for further study of safety computer in signalling equipments. |
