Description

Train platform safety alarm device and control method

The present invention is an apparatus and method for preventing the occurrence of an accident caused by a passenger entering a platform in the station premises, or when a train in the station is leaving the platform, invading the safety line In particular, after the installation of the intrusion detection means for detecting the intrusion of passengers around the safety line of the platform, and detecting the intrusion of the passenger safety line through the intrusion detection means at the time of entry or departure of the train, invade the safety line When it is determined that there is a passenger, an alarm signal indicating this is generated and notified to the passenger and the engineer, so as to prevent an accident caused by the passenger who invades the safety line.

As is well known, the train platform is marked with a safety line indicating the safety distance the passengers and the train must maintain until the train is completed or the departure is completed. The announcements are made to maintain the distance.

For example, in the case of the subway, "... the train is arriving, so passengers should step away from the safety line ...", or "... the train is leaving, so passengers should step back from the safety line. ... ", and guide broadcasts, such as to ensure the safe distance beyond the safety line.

However, in the conventional method of inducing a secure distance between the passenger and the train, there is no other method that can be sanctioned if the passenger does not observe the announcement even if the announcement is broadcast.

Therefore, there is a problem in that accidents frequently occur such that passengers fall off the train tracks, train doors, gaps connecting trains and trains, or trains are left with passengers stuck in the gap between trains and platforms.

Therefore, in order to prevent this, cameras and monitors were installed around the platform for the engineer to check the situation of the platform, or a separate safety officer was placed on the platform to sanction passengers who invade the safety line.

However, the above-mentioned method is, firstly, because of the number of passengers, the monitor cannot identify the passenger's trend, or when the driver cannot find a passenger who is in danger due to breaking the safety line, this may cause an accident. Second, there is a problem that limited safety personnel cannot sanction a large number of passengers. Third, passengers who push behind to board a train do not know the situation for the front passengers. There was a problem that puts you in a dangerous situation.

This will be described again with the example of the subway as follows.

As is well known, the subway platform has yellow safety lines indicating the subway and passenger safety distances, and signs (line or structure) indicating the opening and closing positions of the doors on the floor. Cameras and monitors are installed on the ceiling, and voice guidance devices and broadcasting facilities are provided to guide and broadcast attention to passengers.

First, when the subway enters a predetermined distance from the platform, it is called ATS (AUTOMATIC TRAIN STOPPER: ATS), ATC (AUTOMATIC TRAIN CONTROL: Train ATC). , ATO (AUTOMATIC TRAIN OPERATION: train automatic driving device: ATO) is detected by the automatic operation device of the train, and the announcement of the entrance of the subway through the voice guidance system to inform the entrance of the safety line (information broadcast) Example: "... the train is arriving, so passengers should step back from the safety line,"). The crew broadcasts the attention and the security personnel control the behavior of the passengers to prevent them from breaking the safety line.

However, if there are a lot of waiting people on the platform to push each other (which is more severe during commute times with lots of passengers), the passengers in the rear row are pushed by the passengers in the front row, which invades the safety line. A collision accident occurs or a fatal accident that causes the passenger to fall into the track, there was a problem that can not be restrained by the announcement or limited safety personnel.

That is, the passengers in the rear row cannot know the situation of the passengers in the front row, and they are often pushed by the passengers pushing back, so the above situation occurs.

In addition, when the subway has completed the getting on and off of the passengers in the platform, the announcements indicating the departure of the platform via the voice guidance device, the station broadcasting facility and the broadcasting device of the subway, and at the same time to inform the prevention of intrusion of the safety line (eg: "... the train is leaving, so passengers should step back from the safety line,", etc.), check the door open status, and watch the situation of the platform displayed on the monitor to leave the subway. At this time, the safety officer controls the behavior of the passengers to prevent invasion of the safety line.

However, if this situation also pushes a lot of passengers to board the platform, it is impossible to pinpoint the danger situation of the passengers as well as the sanctions, so that the passenger's feet are caught between the subway and the platform, There were problems such as an accident that the subway would leave with passengers caught in the gap between the train and the train.

In other words, the passengers in the rear row do not grasp the danger situation of the passengers in the front row and keep pushing, and it is difficult for the crew and the safety officers to grasp it properly, and the passengers start the subway despite the danger. There was a problem. This is worse when the station is curved.

An object of the present invention is to solve the above-mentioned conventional problems, in particular, by continuously detecting whether the passengers invade the safety line when the train enters the platform, or when the train is leaving the platform, invading the safety line When a passenger is detected, an alarm signal is generated to alert the passenger or the crew to prevent accidents caused by passengers breaking into the safety line, as well as reducing unnecessary waste of personnel. Device and a method of controlling the same.

In order to achieve the above object, the present invention "train station safety warning device" continuously detects the presence or absence of a train entering the platform, and when a train entering the platform is detected, a predetermined signal indicating this is detected. Generated entry detecting means; A driving detection means for continuously detecting whether a train entering the platform is moved, detecting a stop, start, and departure of the train and generating a signal indicating the same; An intrusion detecting means installed along a safety line of the platform to detect and output whether the passenger invades the safety line; Alarm means which is operated by a predetermined signal to generate an alarm signal indicative of intrusion of a safety line of a passenger; Connected between the entry detecting means, the driving detecting means, the signal output terminal of the intrusion detecting means, and the signal input terminal of the alarming means to continuously detect a signal input from the entry detecting means or the driving detecting means, When a signal indicating the entry of the train into the platform from the entry detection means is input, the driving detection means detects whether the passenger is invading the safety line through the intrusion detection means until a signal indicating the stop of the train is input, and the passenger invades the safety line. If it is determined that the alarm signal indicating this to generate the signal to the alarm means, and second, when the signal from the driving detection means that the train is stopped at the platform has started the departure, the driving detection means The intrusion detection means until a signal indicating completion of departure of the train It is characterized in that the technical configuration is configured to include a microcomputer to detect whether the intrusion of the passenger through the safety line through the passenger, and to apply a signal to the alarm means to generate an alarm signal indicating that the passenger invaded the safety line. .

In the above, the departure from the platform means that the train has left and completely exited the station premises. Same as below.

In addition, the entrance detecting means is installed in a track section located at a distance to secure a braking safety distance for the prescribed speed of the train entering the platform, characterized in that configured to detect the entering train to generate a signal indicating this do.

For example, the switch terminal is configured using both tracks, and the switch is turned on or off due to the entry of the train to detect the entry of the train, or an ultrasonic sensor or an infrared sensor is provided on one side of the track.

In addition, a contact sensor, an infrared sensor, an ultrasonic sensor, a vibration detection sensor, and the like are provided at the stop position of the train and a little past the stop position, respectively, to stop the train when the train arrives at the stop position. When the train starts to be detected by the sensor installed through the train to the start of the train, when the train is no longer detected by the sensor installed through the stop line to recognize the completion of the train platform departure.

In addition, the operation detecting means, by detecting whether the stop, departure, departure of the train from the information on the operation of the train detected by the automatic control system of train operation, such as ATS, ATC, ATO, and outputs a signal indicating this It is done.

For example, by connecting a train operation automatic control device such as ATS, ATC, ATO, etc. through a communication device such as a modem, while continuously detecting the presence or absence of a signal for stopping, starting, or completing a train, the train departure signal is detected. If it is configured to output a signal indicating this.

In addition, the intrusion detection means is characterized in that it is composed of one or more optical sensors having a transmitting unit and a receiving unit arranged in a row or in a row along the safety line of the platform.

For example, a plurality of infrared sensors along a safety line (if the safety line (curve) is curved, along the curvature of the curve) "Transmitter ---> Receiver, Transmitter ---> Receiver, Transmitter ---> Receiver" A receiver unit (for example, a CdS photoconductive cell) for receiving the light by arranging the intrusion detection means by arranging or arranging in a row as in the above, or by installing a light having a straight characteristic (eg, a search light) at one end of the platform. , PbS photoconductive cells, phototransistors, solar integrated panels, etc.) at the other end of the platform, and then install reflectors along the curvature of the platform (directly if straight) to form an optical path parallel to the safety line. Configure. Then, if light is normally received in the receiver, there is no passenger who broke into the safety line. Otherwise, there is a passenger who broke into the safety line.

<Example>

In this embodiment, a known infrared sensor composed of a transmitter and a receiver is used as the detection means of the entry detecting means, the driving detecting means and the intrusion detecting means.

The reason for using the infrared sensor is because of the linearity of the signal (light).

In addition, the alarm means is configured using both an alarm sound generating device, an alarm light and a voice guidance device.

Here, the alarm sound generating device uses a predetermined melody or a known alarm sound generating device for generating an alarm sound, and a plurality of lamps are used as the alarm light. In addition, the voice guide device is configured to store and synthesize the voice data such as "dangerous. Please step away from the safety line" to the known voice synthesizer.

Thereafter, as shown in FIG. 1, the signal output terminal of the entry detecting means 10, the driving detecting means 20, and the intrusion detecting means 30 is connected to the signal input terminal of the microcomputer 40. The control signal output terminal 40 is connected to the alarm sound generating device 51 of the alarm means 50, the warning lamp 52, and the control signal input terminal of the voice guidance device 53 to constitute the present embodiment.

In addition, as shown in FIG. 3, the transmitter 10a of the infrared sensor constituting the entry detecting means 10 at a position to secure a braking safety distance for a prescribed speed of the train 1 entering the platform 4. ) And a receiving unit 10b, and a driving detecting means for detecting the entry of the train into the stop position 3 (i.e., detecting whether the train is stopped) at the stop position 3 at which the train 1 stops ( The transmitter 20a and the receiver 20b of the first infrared sensor of 20) are provided, and the transmitter 20c of the second infrared sensor of the driving detection means 20 for detecting the start of the train in front of the stop position 3 is provided. And receiver 20d are provided respectively.

In addition, a plurality of infrared sensors along the safety line 5 is installed on the floor of the landing as shown in FIG. In this embodiment, the platform is divided into six sections, and six infrared sensors are used to detect the intrusion of safety lines occurring in the sections. At this time, the infrared sensor, as shown in the figure "transmitter 30a-> receiver 30b, transmitter 30a-> receiver 30b, transmitter 30a-> ...-> receiver (30b) "in order.

In addition, between the safety line 5 and the track 2b, a plurality of warning lights 52 of the alarm means 50 are arranged and installed on the floor of the platform (or a position that the passenger can easily recognize). In this embodiment, as shown in Fig. 3, after arranging a plurality of warning lights (lamps) in a line outside the safety line 5, it is installed so as to be divided into six sections a to f to operate. That is, when a safety line intrusion occurs in any one of the six sections a to f and detected by the corresponding infrared sensor of the intrusion detecting means 30, the section in which the infrared sensor is in charge (that is, It is configured such that the warning lamp of the section in which the intrusion of the safety line occurs is turned on or flashes.

In addition, a speaker (not shown) of the alarm sound generating means 51 constituting the alarm means 50 and a speaker (not shown) of the voice guidance device 53 are placed at a predetermined position (ceiling or side of the platform, or invading the platform). A plurality of detection means 30 or a position where the warning light 52 is installed) can be installed so that both the passenger and the driver of the train can be recognized.

In addition, the microcomputer 40 detects the train by the second infrared sensor 20c or 20d after the stop of the train 1 is detected through the first infrared sensors 20a and 20b of the driving detection means 20. When it is made to recognize this as the start signal of the train, when the presence of the train 1 is detected in the second infrared sensor (20c, 20d) and stopped, it is internally programmed to recognize it as the departure complete signal of the train.

In addition, in FIG. 3, only one transmitting unit and a receiving unit are connected to the microcomputer 40 among the six infrared sensors constituting the intrusion detecting means 30 in the drawing. Note that the transmitter and receiver of the infrared sensor are connected. The same applies to the connection of the warning lamp 52 and the driving detection means 20.

In the drawings, reference numerals 2a, 2b, and 2c denote track sections.

Hereinafter, the operation of the present invention "train station safety warning device and its control method" configured as described above in detail.

First, as shown in FIG. 2, the microcomputer 40 continuously detects a signal input from the receiving unit 10b of the entry detecting means 10 to determine whether the train has entered a predetermined position from the landing 4. The entrance detection step (S11) for detecting whether or not is performed.

That is, continuously detecting whether the infrared rays transmitted from the transmitter 10a are received by the receiver 10b, and when no more infrared rays are received due to the entry of the train 1, it is recognized as the entry of the train. .

On the other hand, when the train 1 entering the platform as a result of performing the entry detection step (S11) is detected, the signal input from the receiver 30b of each infrared sensor constituting the intrusion detection means 30 By performing the intrusion detection step (S12) to detect continuously whether the intrusion of the safety line 5 until the train stops.

In addition, if it is determined that the safety line 1 is intruded as a result of performing the intrusion detection step (S12), the alarm signal that indicates this is an alarm that is continuously generated until the safety line invasion is canceled or the train stops. After performing the signal generation step (S13), the operation detection means 20 detects whether the train is stopped, if it is determined that the train is not stopped to repeat the intrusion detection step (S12) or less will be.

This will be described in detail as follows.

First, when it is determined that the train 1 enters the platform 4 as a result of performing the entry detection step S11, the safety line is detected by detecting a signal output from each infrared sensor constituting the intrusion detecting means 30. It is determined whether or not 5) has been invaded.

Here, each of the six infrared sensors constituting the intrusion detecting means 30 is operated only when the microcomputer 40 detects the entry of the train 1 to detect the output thereof or to operate the train constantly. When the entry of (1) is detected, the output thereof is detected and judged. In this embodiment, the former is followed.

At this time, if one of the six infrared sensors constituting the intrusion detecting means 30 is not received by the infrared ray transmitted from the corresponding transmission unit 30a in any one of the receiving unit 30b, it is determined that the safety line 5 is invaded In addition, the alarm generating step (S13) is performed to generate an alarm signal indicating that the safety line 5 has been invaded.

That is, while generating the alarm sound through the alarm sound generating means 51, and voice guidance such as "dangerous. Please step away from the safety line" through the voice guidance device 53, flashing the alarm light 52 This will draw the attention of passengers and engineers.

Here, the warning light 52, by blinking only the section in which the safety line is invaded, so that the passengers around it can easily recognize whether the safety line 5 invaded, and the alarm sound and voice guidance is easy for passengers and engineers In order to be able to recognize the operation of the sound generating unit 51 and the voice guidance device 53 in the corresponding section and the driver's place. Here, the alarm sound generating means 51 and the voice guide device 53, after connecting a plurality of speakers are installed, it is possible to operate only the speaker at the corresponding position by the control of the microcomputer.

The generated alarm signal lasts until the intrusion of the safety line 5 is eliminated or a signal indicating that the train 1 is stopped at the receiver 20b of the first infrared sensor of the driving detection means 20 is detected. Will be. This is because after the train 1 stops, passengers get on and off, and thus no alarm signal is required.

On the other hand, after performing the access warning step (S10), the microcomputer 40 continuously detects whether the train platform departure from the signal applied from the receiving unit 20d of the second infrared sensor of the driving detection means 20. When it is determined that the departure detection step S21 and the departure detection step S21 are performed as a result of the departure of the train 1 from the platform 4, the safety line 5 is provided through the intrusion detection means 30. Intrusion detection step (S22) and continuously detects whether the intrusion of the train (1) until the departure of the platform (4) and the intrusion detection step (S22) as a result, the safety line 5 is invaded If it is determined that the alarm signal indicating this, the alarm signal generating step (S23) and the intrusion detection step (S22) continuously generated until the safety line intrusion is eliminated, or the departure of the platform is completed, after performing Departure from the platform of the train via the driving detection means 20 Determining whether the start of the platform 4 of the train 1 is not completed by continuously detecting whether or not the train 1 is started, the departure consisting of a departure completion detection step (S24) of repeatedly performing the intrusion detection step (S22) or less. The alarm step (S20) is performed sequentially.

That is, after performing the entrance warning step (S10) to generate an alarm signal depending on whether the safety line (5) invades until the train 1 stops on the platform 4, the vehicle detecting means 20 is formed. The signal output from the light receiving unit 20d of the second infrared sensor is continuously detected, and when no more infrared light is received due to the departure of the train 1, it is recognized as starting of the platform 4 of the train 1 By operating the intrusion detection means 30 is to detect whether or not the intrusion of the safety line by the passenger remaining in the landing (4).

This will be described in detail as follows.

First, when the stationary train 1 leaves the platform 4 and is located between the transmitter 20c and the receiver 20d of the second infrared sensor installed in front of the stationary position 3 of the train, the transmitter 20c. Since the infrared rays transmitted from the N-th beam are not incident on the receiver 20d, the receiver 20d outputs a low signal (or a high signal).

Then, the microcomputer 40 recognizes this as the departure of the train 1 and operates each infrared sensor constituting the intrusion detecting means 30 until the departure of the train is completed. , Until a high signal (or a low signal) is output from the receiving unit 20d of the second infrared sensor.

At this time, when intrusion of the safety line 5 is detected in at least one of the receivers 30b of the six infrared sensors constituting the intrusion detecting means 30, the alarm means 50 is operated to generate an alarm signal indicating this. Thus, the generated alarm signal (alarm sound, alarm light, voice guidance) is maintained until the ingress of the safety line 5 or the departure of the platform 1 of the train 1 is completed. This is the same as the operation of the alarm signal generation step (S13) performed in the entry alarm step (S10), the detailed description thereof will be omitted.

As described above, the present invention "train station safety warning device and its control method", when the train enters the platform to perform an alarm for the entry of the safety line (5) by performing the entry alarm step (S10), When the train stops at the platform, the departure warning step (S20) is performed to alert the intruder of the safety line (5) to alert the passengers and the engineer, thereby preventing accidents caused by the intrusion of the safety line. will be.

However, in the above embodiment, the entry detection means and the driving detection means are configured using an infrared sensor having an infrared transmitter and a receiver, but the train control signal output from an automatic train operation control apparatus such as ATS, ATC, ATO, etc. It can be configured that the intrusion detection means and the alarm means can be operated by detecting the entry, stop, departure and departure completion of the train.

In addition, in the above embodiment, although the infrared sensor is used as the intrusion detection means, it can be seen that it can be configured using other intrusion detection sensor. For example, a pressure sensor or a hydraulic sensor is installed along the safety line to detect whether the safety line is invaded from the signal, or light having a linear characteristic (for example, a light source in which the light source is located at the focus of a reflector such as a searchlight) and the like. Reflector and light sensor can be installed along safety line.

In addition, in the above embodiment, although the infrared sensor of the intrusion detection means is installed on the floor of the landing, it is found that it can be installed at a predetermined height from the floor by using a rod of a predetermined length.

In addition, in the above embodiment, although the infrared sensors of the intrusion detection means were installed in a line along the safety line, it can be understood that they can be configured in one or more rows at predetermined intervals.

In addition, in the above embodiment, the structure of the landing platform has been described in the case of a straight line, but it is clear that it is applicable to the curved landing hall by adjusting the angle of the detection sensor transmitting unit and the receiving unit.

In addition, in the above embodiment, the microcomputer is used to control the operation of the entry detecting means, the driving detecting means, the intrusion detecting means and the alarm means, but the TTL element or the logic element is used to perform the role of the microcomputer instead. Note that it can be configured.

As described above, the present invention "train station safety warning device and its control method", when the train enters the platform, or when the train is leaving the platform, by detecting the intrusion of the safety line through the intrusion detection means By alerting, there is an effect to prevent train accidents due to the intrusion of safety lines, and to reduce the manpower by acting as a safety officer.
