PROBLEM TO BE SOLVED: To solve the problem in which when one system of a redundant system stops operation due to malfunction after receiving an influence such as snow, the system is switched to the other system into a single system operation state, and therefore unless the one system is restored as quickly as possible, the other system also stops to cause a system failure and stop the service of a train, in which state even when the stop failure of one system device is caused by an influence due to a transient event, a security guard of a security device (for example, traffic signal or the like) needs to visit a job site and to confirm and restore an abnormality cause, requiring large burden of time and labor in a conventional manner.SOLUTION: The multiple system control device includes means for mutually monitoring a state of a control device, and for making a request for restart of the system which has stopped, and for restarting the system which has stopped in a multiple system configuration. |
