Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an emergency stop warning system for railway vehicles, and more particularly to an emergency stop warning system for railway vehicles from stations and platforms.
[0002]
[Prior art]
The following alarm system is used as this kind of emergency stop alarm system.
As one of them, at the station / platform, a push button switch indicated as "emergency stop button" which is displayed in red is mounted on a pillar of the home building. The first use mode of this is to press the "emergency stop button" in an emergency such as when the train starts moving with the passenger or the passenger's belongings sandwiched between the doors of the train, At least one of a notification that makes the bell attached to the home building ring greatly and a notification that blinks the emergency light is notified to notify the driver / conductor of the train of the occurrence of the emergency, and the driver / conductor is notified of the emergency. This is to stop the train by manual control. As a second mode of use, the output signal of the "emergency stop button" automatically changes the related signal to red or the like to notify the driver or the like of the occurrence of an emergency, or the ATC (Automatic Train Control Device). (Train control device) to stop the incoming train.
[0003]
On the other hand, a communication system using guidance radio between a crew of a railway vehicle and a vehicle operation command room or the like is currently used. One of the communication systems (1) using this type of guided radio is a train radio, and as shown in FIG. 3, a train crew operates an operation unit 20 and a handset 21 to constitute an induction radio facility. , And is connected to a base station 26 via a communication medium such as a transmission antenna 23, a reception antenna 24, and an inductive communication line 25. The base station 26 is integrally controlled by a control device called a central control device 28 via a wired cable 27 or the like, and is configured to be able to communicate (call) with an operation commander at an operation command table 29.
Next, (2), if shown by the communication system shown in FIG. 3, the train crew who has found an emergency modulates the guided radio carrier with a signal called "emergency alert" by operating the operating device 20, The modulated guided radio carrier wave is radiated from the transmitting antenna 23 installed in the vehicle 8, the carrier wave is induced in the guided communication line 25 using the trolley wire 31 as a medium, and the base station 26 receives and demodulates the carrier wave. There is a communication facility for stopping the feed from the substation 30 to the trolley line 31 via the control device 28.
In addition, (3) has a purpose of stopping a running train, and there is one called a guard radio. This is a communication for a train crew who has found an emergency to directly report the emergency to nearby trains, and may be used in combination with the above-mentioned (2) emergency alert.
[0004]
[Problems to be solved by the invention]
By the way, from the viewpoint of ensuring safety at stations and platforms, the fact that precious lives are lost due to personal injury caused by the falling of passengers from railway stations and platforms to the track is that the fall at JR Shin-Okubo station earlier This is a major social problem, not to mention the loss of a rescuer as a precious victim. In addition, once an accident occurs, the traffic by the railway vehicle is always stopped for a limited time necessary for the function of transportation, that is, normal transportation of passengers, to recover from the accident. Cannot be avoided. Therefore, it is an important and urgent task to avoid such a painful accident from both the passengers who use the vehicle and the transportation agencies that operate the railway vehicles.
[0005]
However, with the conventional alarm system as described above, it is impossible to provide a processing measure with a certain effect on such a problem.
That is, in the first usage mode, the alarm system in which the “emergency stop button” is arranged at the station / platform has a maximum alerting range for a train running along the platform or immediately before entering the platform. However, an abnormal situation cannot be reported at all to a train traveling several hundred meters or more from the platform to enter the platform. Further, in the second mode of use, the stop of the train is performed on the condition that the ATC is arranged, so that the train cannot be executed in a section where the ATC is not installed.
Further, any communication system using guided radio has been variously proposed as a communication method between a train crew and communication equipment installed at a specific place. Obviously, since there is no provision, it is not possible to issue a warning from a station or platform to stop a nearby or nearby railcar.
[0006]
An object of the present invention is to reliably transmit an emergency stop warning from a station / platform to a railway vehicle on which passengers or the like are traveling in a state where the safety of passengers on the platform is impaired or in danger of impairing the station. An object of the present invention is to provide an emergency stop warning system from a station or platform to a railway vehicle, which can ensure passenger safety in the platform section.
