Operation security method, operation security systems and management device

摘要

PROBLEM TO BE SOLVED: To provide a new mechanism for restraining a communication quantity between an on-vehicle device and a management device, and achieving smooth train operation and operation security.;SOLUTION: In this operation security system 1000, the on-vehicle device 1 transmits an occupation security request signal of requesting occupation security of a blocking-up section for constituting a travel expected passage to the management device 5. The management device 5 determines the possibility of the occupation security of the blocking-up section for constituting the travel expected passage when receiving a security request signal from the on-vehicle device 1. When being able to occupy the whole blocking-up section for constituting the travel expected passage, it is regarded as occupying the whole blocking-up section for constituting the travel expected passage, and an occupation security signal is transmitted to the on-vehicle device 1. When a train reaches an end point, the on-vehicle device 1 transmits an occupation release request signal of requesting an occupation release of the blocking-up section of the travel expected passage to the management device 5. The management device 5 releases occupation of a blocking-up section except for the blocking-up section of the end point when receiving the release request signal from the on-vehicle device 1.;COPYRIGHT: (C)2012,JPO&INPIT
