PLATFORM SAFETY MONITOR SYSTEM AND SAFETY MONITOR METHOD USING THE SYSTEM

摘要

PURPOSE: To lessen a burden on the station staff, and enhance safety by detecting a passenger or an obstacle at the time of a train ingress or start via the combination of a platform track circuit, a train sensor, a passenger sensor or the like for giving a warning about the existence of a dangerous state and stopping a vehicle. ;CONSTITUTION: A platform track circuit 70 generates an ingress signal 70a at least upon the ingress of a train into a platform. Also, a train sensor 30 operates upon receipt of the signal 70a, and generates a sensing signal 30a at least upon the detection of a train. A train sensor 20 also operates upon receipt of the signal 70a, and generates a sensing signal 20a at least upon the detection of an obstacle over the time from the closure of a train door to the start of a train. On the other hand, a transponder 40 makes a communication in combination with an onboard transponder 41. A safety monitor control means 50 generates a constraint signal 60 to constrain a train start at least upon the detection of an obstacle sensing signal as well as a drive signal 50a for an obstacle indicator lamp 60, and at the same time, diagnoses each of the sensors 20 and 30.;COPYRIGHT: (C)1996,JPO
