Description

[Detailed Description of the Invention] (Industrial Application Field) This invention provides a warning guide for automatically warning and guiding passengers on a platform in a station against dangers such as falling onto the tracks and trespassing cars. Regarding equipment.

(Background of the proposal and conventional technology) Platforms are equipped with stairs leading to viaducts and underpasses connected to them. It has become narrower.

For this reason, we are acutely aware of the need to provide appropriate warnings and guidance to passengers who are passing by or waiting on the platform near the outside of the stairs to prevent them from falling off the platform or from being hit by a car. ing.

However, in the past, only white lines and uneven boards were installed as a warning on the part of the platform facing the tracks (outer part), and a public address system was used to warn passengers all over the platform just before a train entered the track. It is merely evoking.

(Problem to be Solved by the Invention) As described above, in the past, only white lines and uneven boards were provided on the outside of the platform, so during rush hours, nearby passengers could hardly notice such white lines.

Even during off-peak hours, such as during the day, early morning, and late at night, it is difficult for the elderly, young, physically disabled, and drunk people to distinguish white lines, and there is a risk of falling off the platform.

On the other hand, public announcements are generally made only just before a train enters the line, and are not very useful for preventing danger when passing near the outside of the platform.Furthermore, since the announcement is made over the entire platform, it is difficult to sit on a bench. On the contrary, it may feel noisy to the passengers, etc., and it cannot be said to be appropriate.

In view of these circumstances, a means is required to provide intuitive and forcible warnings and guide passengers only near the outside of the platform.

This invention is intended to solve the problems of the prior art and satisfy the above requirements, and is devised to automatically issue a forced warning and guidance to passengers near the outside of the platform when necessary. The purpose of the present invention is to provide a warning guidance device that provides a warning guidance system.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention includes track entry detection means 20 for detecting that a vehicle is stopped on a track facing the platform 1, and a type of platform 1 facing the track. Detection by a passenger detector S3 that detects passengers in the sexual area C, a forced warning device 5.25 for forcibly giving a warning to passengers in the sexual area C and providing safety guidance, and an entry detection means 20 A control device 18 is provided which instructs the forced warning device 5.25 to operate when there is no output and there is a detection output from the passenger detector s3.

(Function) When the vehicle is not stopped on the track facing the platform 1, that is, before the vehicle enters the track, while the vehicle is entering the track, or during the departure operation, the track entry detection means 20 is in operation. When there is a passenger in the sex area C, the passenger detector S is activated, and the control device 18 activates the mandatory warning device 5.
25 is operating.

Due to the operation of this forced warning device 5.25, a forced warning and guidance are given to the passengers in the shaped area C of platform 1, so even during rush hours, the passengers themselves are in danger to the elderly, young children, etc. It is possible to reliably recognize that the passenger is in the fruit juice zone C, and to deal with dangers such as falling onto the railroad tracks or collision with a vehicle. There is no reason to cause trouble with meaningless warnings.

(Example) Hereinafter, embodiments of the present invention will be explained based on the drawings.

Fig. 1 is a block diagram of the configuration of the present invention, Fig. 2 is a side view of the vicinity of platform 1 in a station to which the first embodiment of the invention is applied, and Fig. 3 is a perspective view of Fig. 2. be.

In the vicinity of this platform l, there are provided stairs 2 connected thereto, for example, to an elevated bridge.

The head of a train (vehicle) not shown entering the track from the right in the direction of arrow A and departing to the left on the track (not shown) in front of platform 1 is located at the stop area (stop Location) Park in B.

The sides of the platform 1 on the sides of the stairs 2 and on the sides in front of the entrance of the stairs 2 are molded areas C that are narrower than other areas of the platform 1.

Vehicle detectors S1 and 82 for detecting whether there is a vehicle facing this moldable area C are provided close to the rear and front, respectively, in the direction of arrow MA of the stopping position i1B of the vehicle head.

The vehicle detectors S8 and S2 use reflective infrared sensors, for example.

A passenger detector S3 for detecting whether a passenger is present in the moldable area C is installed on the platform 1 above the moldable area C.
There are multiple locations along the route.

In the illustrated example, a piping duct 4 is run through the upper side of the side wall 3 of the stairs 2 along the platform 1, and a reflective infrared sensor, for example, is used as the passenger detector S3.

Examples of the forced warning device 5 for forcibly giving a warning to passengers in the type zone C and providing safety guidance include a light emitting device 6 that repeatedly blinks and an air blowing device 7 that blows out pressurized air. It is composed of.

The illustrated light emitting device 6 includes a plurality of upper light emitters 8 disposed in the piping duct 4 so as to project light downward in a fan shape.
and a plurality of lower light emitters 9 embedded outside the white line ↓O of the platform 1, each having a light emitting window with a guiding symbol mark such as an arrow or an X mark cut out on its upper surface.

Although not shown, the upper light emitter 8 uses, for example, a tubular xenon sphere as a light source, and uses a long cylindrical lens with a half-moon cross section to emit fan-shaped light in the longitudinal direction as shown by the two-dot chain line in FIG. A plurality of pairs of this light source and a cylindrical lens are arranged so that the longitudinal direction of the cylindrical lens coincides with the longitudinal direction of the piping duct 4.

Although not shown, the lower light emitter 9 uses, for example, a tubular xenon bulb as a light source, and a plurality of pairs of light emitting windows and protective glass in which guide symbol marks such as arrows and X marks are cut out on the platform 1. It is buried along.

The light emitted from the cylindrical lens and the light emitted from the plurality of light emitting windows are connected vertically along the platform 1, forming a narrow and long operating area. This operation area almost coincides with the attention-required area C, making it easier to perform zH.

These upper light emitters 8 and lower light emitters 9 are connected to arrow A
By controlling the lights to blink in one direction or in the opposite direction, it is possible to create a stimulating sensory effect on passengers.

It is also a good idea to use a halogen lamp as a light source so that it can be clearly recognized even during the day.

The air blowing device 7 has a long pipe 11 with its end closed inside the piping duct 4, and a plurality of discharge nozzles 12 for jetting pressurized air downward are arranged in this pipe 11. The pressurized air intermittently ejected from the nozzle 12 forms an air curtain in the area C that requires attention, thereby making the passengers aware that they are in the area C that requires attention.

This air blower device 7 includes a near compressor 13 and an air storage tank 14 for supplying pressurized air to the pipe 11 and respective supply pipes 15 and 16, and a solenoid valve 17 for opening the discharge nozzle 12 intermittently as necessary. We are prepared.

The compulsory warning device 5 consisting of the light emitting device 6 and the air blowing device 7 is controlled by a logic circuit, for example, based on the detection outputs of the vehicle detectors S, S, and the passenger detector S3. According to the commands of the device 18, it operates as follows.

The status of the vehicle, such as whether the vehicle is stopped on the tracks on the side of the area C that requires attention, and whether it is departing, is determined by the vehicle detectors S8, S2 and the discrimination circuit 19 (formed in the control device 18). This is determined by the line entry detection means 20 consisting of

The determination by the determination circuit 19 is as follows.

(1) When only the rear vehicle detector S is in a detection operation (on) for a certain period of time or more, the vehicle is stopped.

(2) When both the rear and front vehicle detectors S8 and S2 are on for a certain period of time or more, the vehicle is departing.

(3) When both the rear and front vehicle detectors S, , S are off, the vehicle has not entered the line.

The control device 18 is equipped with a warning switch 21 for manually operating the compulsory alarm device 5, and a timer 22 for stopping the operation during the station closure period from the last arrival to the first train.

The warning and safety guidance operations in the above embodiment having the above configuration will be explained with reference to FIG.

When no vehicles are on the track and there are passengers in caution area C (case 1), the rear vehicle detector S1 is off and the passenger detector S is on, so a mandatory warning system is activated. 5 works.

In case 2), when a vehicle that has entered the track is departing and there are passengers in the caution area C, the rear and front vehicle detectors S8
, S2 and the passenger detector S3 are both on, so the forced warning device 5 operates.

When the compulsory warning device 5 operates, the upper light emitter 8 and the lower light emitter 9 act on the passengers in the caution area C by blinking sequentially, and at the same time, the discharge nozzle 12 supplies pressurized air to the passengers. Passengers can be sure to know that they are in the dangerous Caution Area C because the air is ejected towards them.

Since such light projection and air blowing actions are performed only in the caution area C, other passengers on this platform who are outside the caution area C will not be inconvenienced by meaningless warnings. do not have.

The above warning is particularly effective in preventing falls onto the tracks in case 1, and in case 2 it is useful in preventing collisions with on-going vehicles. It has become especially useful for the elderly, the disabled, and even drunks.

On the other hand, when the vehicle is stopped, the rear vehicle detector S1 is turned on and the front vehicle detector S2 is turned off for more than a certain period of time, and the forced warning device 5 operates regardless of whether there are passengers or not (Case 4). do not.

When the train is stationary, there is no risk of falling onto the tracks, and there is no risk of a car accident, so unnecessary warnings are not given to passengers.

Even when the vehicle is departing, the mandatory warning device 5 does not operate when there are no passengers in the type area C (case 5).

The configuration block diagram of the second embodiment of this invention is shown in FIG. 5, and the platform 1 to which this second embodiment is applied is shown in FIG.
A side view of each is shown in Fig. 6.

Components that are the same as those of the first embodiment shown in FIGS. 1 and 2 are designated by the same reference numerals, and the structural description thereof will be omitted.

In this second embodiment, a voice transmission device 24 is used instead of the air blowing device 7 in the first embodiment, and is combined with the light emitting device 6 to form a forced warning device 25. has the same functions as the first embodiment.

The illustrated voice transmission device 24 has a long voice transmission tube 26 with its end closed inside the piping duct 4, a plurality of leak holes 27 that can leak sound downward, and a plurality of leak holes 27 that can leak sound downward. A speaker 28 is connected to the base end, and a sound source 29 such as a tape recorder or an audio ROM that records chimes, voices, music, birdsong, etc. is amplified by an amplifier 30 as appropriate and connected to the speaker 28.

Voices, music, etc. generated from the sound source 29 are amplified and tempered by the amplifier 3o and the speaker 28, and are leaked downward from each leak hole 27 of the speaking tube 26, forming a band shape on the shaped area C and being perceived by the passengers. be done.

If the speaking tube 26 is placed at a position, for example, 50 cm from the ears of the passengers in the attention-required area C, the output will be small, and as a result, almost no voice will leak outside the attention-required area C. C
There will be no inconvenience to passengers outside.

In this second embodiment, as in the first embodiment, the attention-required area C is
Since reliable warnings and safety guidance are automatically given only to passengers inside the area, it is effective in preventing falls and collisions with vehicles, and furthermore, such warnings, etc., are provided to other passengers outside the caution area C. Since it does not cause any noise or nuisance, it is ideal as a warning and guidance device on Platform 1, where a large number of passengers pass.

Vehicle detectors S1, S2 and passenger detector S used in this invention
3. The forced warning device 5.25, such as the upper light emitter 8, the lower light emitter 9, and the air blower 7, is not limited to the structure of the above embodiment, but has a function that meets the above object of the present invention. Various other structures can be used as long as they are suitable.

The present invention can also be applied without any problem by using the outer side of the platform 1 other than the outer side of the stairs 2 as the molding area.

(Effects of the Invention) As described above, according to the present invention, when passengers in the caution area C of the platform 1 are not stopped when there is a risk of falling onto the tracks or being touched by a vehicle, the mandatory warning device 5 is activated. .2
5 automatically operates to provide a mandatory warning and guidance to passengers in the caution area C.

Therefore, during rush hours or for the elderly and young children, the passengers can be sure that they are aware that they are in the dangerous juice area C, and can take precautions against dangers such as falling onto the tracks or accidents caused by collisions with vehicles. In addition, the system does not cause any inconvenience to passengers outside the attention-required area C due to meaningless warnings, making it ideal as a warning guidance device for platform 1, where a large number of passengers pass.
