Because of the high demanding of the reliability in the railway signaling field
the system structure in which the redundant problem is studied is designed
a controller of the embedded automatic block is designed and a safety controlling lock principle is also proposed in this paper.This paper detailed designed the hardware of the property redundancy controller
comparator circuit and safty controlling lock.By the way
the Petri net theory is used to model and analyze the system as used the controller.
