Description
Technical Field
The invention relates to a device and a method for controlling platform doors on a platform.
Background
In recent years it has become more and more common to separate the track area from the platform in the station, most often separated by a glass barrier wall with "platform doors". This not only improves the safety of passengers, but also enables the station to operate the air conditioner more economically in terms of energy.
Various methods and devices are known for controlling platform and train doors in such a way that the opening and closing of the platform and train doors are synchronized as much as possible. German patent No. DE 102004045558B 3 describes a method for controlling doors of a rail vehicle and corresponding doors on a platform barrier wall, wherein the availability of the doors of the vehicle and the platform barrier wall (presence of the doors and their utility) is transmitted and processed between the vehicle and the platform via a wirelessly supported data exchange channel before the vehicle stops at the next platform and is then transmitted to a passenger information system on the vehicle and the platform. On the platform, communication between the respective doors is performed via an infrared interface.
In document GB 2436152 a, an arrangement is described for controlling the doors of a rail vehicle and the doors of a platform barrier wall, wherein a dedicated transceiver is provided on each door of the vehicle and on each door of the platform barrier wall. Communication between the doors of the vehicle and the doors of the platform barrier wall is made directly through respective transceivers, and control commands for the doors are issued from the vehicle.
A method and a system for the synchronous control of platform and train doors are known from WO2011/069503 a1 and have proven particularly successful in practice. In this arrangement, after the train stops, a communication connection is established between the door control unit on the train and the door control unit on the platform, and the synchronous opening and closing of the train doors and the platform doors is controlled in a coordinated manner between the control units through the communication connection, wherein preferably pairs of train doors and platform doors are formed opposite to each other, and each pair of train door and platform door can be controlled individually without reference to any other pair of doors. With this arrangement, for example, if a train door fails, the train door and the corresponding platform door can be closed while the other doors are open. Clip protection may also be provided for a particular pair of doors so that if an obstruction is detected during closing of the doors, only the respective pair of train and platform doors may be opened, while the other pairs of doors are both closed.
Platform barrier wall systems are often employed on platforms carrying heavy traffic, where trains often stop less than a minute from each other. Thus, any cause of failure in the control of the opening and closing of the platform doors can lead to a confusion of schedule and operation in the associated track network. There is therefore an urgent need for a backup system that can reliably control the opening and closing of platform doors in the event of an interruption in the communication between the train and the platform.
Disclosure of Invention
The object of the present invention is to describe a facility and a method for controlling the opening and closing of a train door, with which it is possible to open and close the train door substantially simultaneously with a station door if the communication link between the control unit for controlling the train door and the control unit for controlling the station door fails.
The above object is achieved with a device having the features of claim 1 and with a method having the features of claim 4. Independent claim 10 relates to the use of an installation with a plurality of sensors for creating a backup system for controlling the opening and closing of platform doors. The dependent claims relate to preferred variants and implementations.
The invention enables the device to be immediately involved when a communication link between the train door controller and the platform door controller is in failure, and enables the platform door and the train door to be almost synchronously opened and closed, so that passengers can not be aware of the failure of the communication link, and particularly can not delay the running process of a train.
Further details and advantages of the invention will become apparent from the following description of preferred embodiments and demonstration models, given by way of example only and not by way of limitation.
Detailed Description
The installation according to the invention comprises: a door control unit on the platform for controlling opening and closing of a platform door of the platform on which a platform barrier wall for separating the platform and the track area is installed, and means for establishing a communication link between the door control unit on the platform and the control unit for controlling opening and closing of train doors of a train parked on the platform.
To establish a communication link, the wireless transceiver unit operates in a low frequency range of about 50 to 200 kHz. With these devices, as described in WO2011/069503 a1, a communication link can be established between the control unit on the train and the control unit on the platform, and through this communication link the opening and closing of the train and platform doors can be synchronized. In this context, a train door controller is typically the master system that determines when the door is opened and closed, while the platform door controller system follows its instructions. A higher level controller may also be provided for fully automatically controlling train operation so that the train can operate without a train operator. Such a controller may thus act as a master system and may also be able to control the operation of the platform doors. Although it is necessary to establish a link between such a controller and a train without an operator to ensure the safety of train operation, since the facility according to the present invention allows the platform door to be controlled according to the opening and closing of the train door without communicating with the train or a higher-level controller, the link with the platform door can be interrupted.
The above mentioned frequency ranges have the advantage that: the link established therewith is not disturbed by wireless signals transmitted by the mobile phone, the wireless local area network or the bluetooth connection. Furthermore, the respective transceiver units can easily be designed such that the signal strength required for a good received signal is advantageously attenuated relatively quickly, in particular in a propagation range of about 60 to 80 cm, so that the offset between the transceiver unit on the platform and the transceiver unit on the train can also be determined on the basis of the strength of the communication link established therewith and can thus be used to determine whether the train is operating correctly.
In the present context, the term "correct operation" is understood in a general manner, meaning that the train is parked in a position: in this position the train doors are located opposite the platform doors in such a way that passengers can pass from the train to the platform and vice versa. Because the platform doors are typically slightly wider than the train doors, the train can stop within certain tolerances.
Since the present invention aims to provide the ability to accurately control the opening and closing of platform doors when the communication link between the train and the platform is interrupted or cannot be established at all, according to the present invention there is provided a device capable of functioning independently of the communication link to capture the correct stopping of the train on the platform. These means may include, for example, a series of light barriers located at the front or rear end region or wheel region of a train and capable of detecting the presence of the train in a particular area, an RFID chip reader unit on a platform capable of reading an RFID chip on the train when the train is about to stop in a particular area, and/or an image capture and analysis unit capable of capturing and analyzing an image of a track area. Particularly preferred are "wheel or axle sensors" mounted on the track to detect whether the wheels or axles of the rail vehicle are located at a specific position. If the vehicle is equipped with rubber wheels, as is the case with some monorail systems, for example, the train position can also be determined using electromagnetic induction coils.
In a presently preferred embodiment, three wheel sensors are mounted on the platform to determine that the train is properly parked alongside the platform, one sensor located in the front area of the train, one in the middle area, and one in the rear. If the sensors generate information different from each other, erroneous information may be generated. Since it is unlikely that two sensors will fail simultaneously, for purposes of the subsequent procedure, if two sensors determine that the train has stopped at the correct location, but the third sensor does not detect the train, it can be assumed that the train has stopped correctly and the platform door can be opened and closed in the manner described below. At the same time, an error message may be generated signaling a failure of the sensor so that the sensor can be replaced.
According to the invention, means are also provided for capturing the opening and closing of the doors of a train parked at a platform, wherein these means can also function independently of the communication link. The device may be of various designs and may include, for example, a camera, a laser range finder, a laser scanner, an ultrasonic transceiver, a microphone, and/or an RFID chip reader unit. The precise mode of operation of the device will be discussed more fully below.
The arrangement according to the invention also comprises means for identifying faults in the data communication enabling the opening and closing of the train and platform doors to be synchronized. Preferably, the devices are computer-based implementations and their design may be optimized differently for their respective operational applications depending on the configuration of the device used to establish the data communication link. For example, they can be designed in the form of a software module which compares the signals emitted by the means for detecting the opening and closing of the train door with the state of the train door reported to the platform door control unit via the communication link. As will be explained below, since the means for capturing the opening and closing of the train doors are of redundant design, it can be concluded that the communication link is faulty if the comparison shows that a deviation occurs between the state of the door providing the communication link report and the state of the door actually captured. Of course, the term "error" is also understood here to mean the situation in which a communication link which enables the train door and the platform door to be synchronized cannot be established.
The facility according to the invention enables the platform door control unit to be designed in such a way that it is capable of controlling the opening and closing of the platform door independently of the communication link in the event of an error in the communication link, wherein said platform door control unit normally transmits to the platform door a command transmitted by, for example, a train door control unit or a higher-level control unit for controlling the operation of an automatic train, to open and close the platform door when the communication link is functioning normally.
In a preferred embodiment, the facility includes means for outputting a train waiting signal controlled by the platform door control unit. This variant advantageously makes it possible to prevent a train departure in the event that the platform door remains open for whatever reason, but this state is not reported to the train operator or the control unit of the automatically operated train due to an error in the communication link.
The method according to the invention can function, for example, in the following manner: as described in WO2011/069503 a1, after a train enters a station, a communication link between the platform door control unit and the train door control unit is established and enabled. Independent of the start-up procedure of the set-up communication link, which may or may not be successfully started, the correct stop position of the train is captured on the platform, in particular by means of wheel sensors, induction coils or other means suitable for the respective implementation location and the availability of the location.
If a communication link is created, it can be used, for example, to synchronize the opening and closing of train and platform doors in such a way that a train door control unit as the main system initiates the opening and closing of train and platform doors.
According to the present invention, the opening and closing of the doors of the train parked on the platform is captured regardless of the existence of the communication link between the platform door control unit and the train door control unit, and the above-described process can also be implemented in various ways depending on the operation place and the available equipment at the place. Devices known per se, such as laser range finders, can be arranged in the region of one or preferably more platform doors on the platform, wherein each device scans the doors of a train parked at the platform, so that the opening and closing of the train doors can be captured by suitable signal analysis.
In a particularly preferred embodiment, the laser scanners are used to detect the opening and closing of train doors and are fixed in the platform door area, each of which not only selectively scans the train doors, which may lead to measurement errors in this case, but also is able to scan an area of a given surface or angle, for example an area of 90 degrees in a measurement plane inclined downwards from the laser scanner mounted firmly above the platform door, and to measure the distance between the respective laser scanner and the object located in front of it. The data is transmitted to an electronic analysis unit. The measuring plane can be adjusted, for example, such that the laser distance measuring device can capture the sleeper when no train is present on the platform. When a train enters a station, a laser scanner detects the train surface with the doors in a closed state. If the train has been parked in such a way that the train and the platform are opposite to and facing each other, the laser scanner detects the opening and closing of the train doors by scanning at least a part of the width of the train door opening. The laser scanner continuously scans the space in front of it, so that changes in the position of the train doors can be detected and the movements of the train doors can be controlled accordingly. The laser scanners may be arranged to scan the opening through which the train doors open, or if the train doors slide along the outside of the train during opening and closing, they may be able to scan the area of the train outer wall over which the train doors slide during opening and closing, depending on the type of train door.
Alternatively, or in addition to the laser scanner, a camera may be installed at each of one or more platform door areas to capture the opening and closing of train doors by analyzing video images of the train doors.
The opening and closing of the train doors can also be captured by means of a measurement of the ultrasonic operating time with a corresponding ultrasonic transceiver arranged in the area of the platform doors.
Since RFID chips and corresponding reader units are becoming cheaper and since RFID chips can also be mounted easily on train doors, it is also possible to mount RFID chip reader units in the area of platform doors, for example three or more reader units side by side capturing the RFID chips mounted on train doors parked at a platform along the above-mentioned sensor direction and their movement with the opening and closing of the train doors.
Since train doors often generate certain distinctive noise and sound wave signals when opening and closing, the opening and closing of the train doors can be captured by analyzing the sound wave signals received by one or more microphones installed in the platform door area.
According to the present invention, the presence of a communication link error between the platform door control unit and the train door control unit can be determined by, for example, comparing data transmitted from the means for capturing a proper stop of the train with data transmitted from the means for establishing a communication link. It may for example be that the means for capturing the correct stopping position of the train has determined that the train has stopped at the correct position so that passengers can get off and get on, however a communication link has not been established. It is also possible that, although the communication link between the platform door control unit and the train door control unit has been established, the platform door control is not registered by the train door control unit due to an error of the communication link, and the means for capturing opening and closing of the train door captures movement of the train door when the train door is opened or closed. In such a case, the platform door control unit obtains the autonomy independent of the train door control unit, so that it does not have to wait for any information from the train door control unit, but can control the opening and closing of the platform door based on the captured opening and closing of the train door. In this case, the platform door can be moved immediately following the movement of the train door, it being advantageously provided that in the event of a failure of the communication link the platform door is moved at a slightly higher speed than in the case of normal operation of the communication link, in order to ensure that no time delay perceptible to the passenger occurs between the train door movement and the platform door movement.
It is advantageous for the platform door control unit to generate the train waiting signal at least when there is a failure in the communication link between the platform door control unit and the train door control unit. In this context, such waiting signals can be visually transmitted in a known manner. If the train is operated in a fully automatic manner, i.e. without a train operator, no visual signal has to be output. The wait signal may be output in other modes such as machine readable, including indirectly cutting off the supply of current required for movement of the electric train whenever the platform door is open.
Since in modern trains the opening and closing of the train doors is usually centrally controlled in a synchronized opening and closing manner for all train doors, it is theoretically sufficient to monitor the opening and closing of a single train door. However, it is advantageous to capture the opening and closing of at least three train doors, in particular one train door located at the front section of the train, one train door located at the middle section of the train and one train door located at the rear section of the train, preferably by means of three sensor devices of the same or different types, which operate independently and separately. In this way, a redundant system is created so that the system can operate reliably even if one sensor device fails.
A failure or malfunction of a sensor device, such as one of the laser scanner devices described hereinbefore, can be detected by successively comparing the results from all three sensor devices.
Finally, the invention also relates to the use of a device having a plurality of spatially separated sensors for detecting the correct stopping position of a train on a platform provided with platform doors and a plurality of spatially separated sensors for capturing the opening and closing of train doors of a train stopping on a platform as a backup system for a controller for the opening and closing of the platform doors. Thus, the backup system can take control over the opening and closing functions of the platform door when the communication link cannot be established or if the communication link between the platform door control unit and the control unit controlling the train door fails.
In the case of a fully automatic system, the train without a vehicle operator uses a central control mode, the control unit controlling the train doors also being responsible for controlling the platform doors. To ensure smooth operation, a substitute control is provided on the platform, which takes over the opening and closing of the platform doors on the basis of the recorded opening and closing of the train doors if a connection to the central control is not established.
