Abstract

PROBLEM TO BE SOLVED: To hold down any possible personal injury to the minimum by judging such a train accident that a passenger aboard is actually dragged in keeping the passenger caught by car doors intact in particular at a platform in the crowded station yard after ascertaining it accurately, and stopping the train quickly and exactly. SOLUTION: At a time when such a situation that a passenger on a platform at the station yard is dragged in keeping the passenger caught by car doors intact has happened immediately after the departure of a train 3, a dynamic moving state due to abnormal movements of the passenger is detected by a personal dynamic moving state detection sensor 4. A light out of a light emitting means 6 installed in a train hindmost vehicle 3n is received by a light receiving means 5, and the passenger dynamic speed calculated by a dynamic speed measuring means 10 and the train speed calculated a train speed measuring means 11 are comparatively judged by a speed data processor 12, and in the case where both speeds are accorded with each other, the train 3 is emergently stopped by a emergency stop signal from a protective wireless part 13.

FIG. 3 is a block diagram showing a system configuration of the present embodiment using the above-described devices and equipment. First, there is provided a dynamic speed measuring means 10 to which a signal obtained by detecting the dynamic state of the passenger 7 on the platform 1 by the above-mentioned human dynamic state detection sensor 4 provided at one meter intervals is inputted. It also has a train speed measuring means 11,
Here, a signal indicating that light emitted by the light emitter 6 of the last vehicle 3n is received by the light receiver 5 provided at one meter intervals on the home side wall 1a is input.

Further, the system includes a speed data processing unit 1
2 and a protection radio unit 13. The speed data processing unit 12 receives the respective speed measurement value signals from the dynamic speed measurement means 10 and the train speed measurement means 11, and compares the two speed measurement values to determine whether they match. . The protection wireless device 13 includes the speed data processing unit 1
2, a command signal based on the determination is received, and an emergency stop signal is wirelessly output and transmitted to the train 3 that is departing.

Therefore, with such a configuration, the train personal injury prevention system of the present embodiment operates and operates as follows.

Suppose that a situation has occurred on the platform 1 where the passenger 7 is unfortunately dragged while being sandwiched between the doors of the train 3 where the train 7 has started to depart. The movement of the passenger 7 who has been dragged is detected one after another by the human movement detection sensor 4 provided at every other meter on the roof beam above the body. This dynamic detection signal is transmitted to the dynamic velocity measuring means 10.
Sent to The dynamic speed measuring means 10 receives a dynamic detection signal due to the dragging movement of the passenger 7 sent one after another from the human physical movement detection sensor 4 and calculates the dynamic speed of the passenger 7 based on the correlation between the moving distance and time. The calculated value of the dynamic speed of the passenger 7 is sent to the speed data processing unit 12 as a converted signal.

On the other hand, in synchronization with the processing for the passenger 7, on the other hand, the light emitting device 6 provided on the last vehicle 3n of the train 3 which starts and travels moves. The light emitted from the moving light emitting device 6 is sequentially received by the light receiving device 5 provided at every other meter on the home side wall 1a, and a detection signal of the received light is sent to the train speed measuring means 11 in order. The train speed measuring means 11 receives light-receiving signals successively transmitted from the light-receiving devices 5 every other meter, and calculates the speed of the train 3 based on the correlation between the moving distance and time. The calculated value of the traveling speed of the train 3 is sent to the speed data processing unit 12 as a converted signal.
