Abstract

A process is disclosed for automatically controlling the movements of a vehicle door (7) and of a matching station door (9) in a public transport system (1). In order to co-ordinate the movements of the doors in a particularly simple manner, a corresponding control signal is directly transmitted between the matching doors (7, 9). In order to control a co-ordinated movement, a first control system (15) is associated with the vehicle door (7) and a second control system (20) is associated with the matching station door (9). Advantageously, a local door control (13a, 16a) is associated with each door (7, 9).

Description

The invention relates to a method for automatic control the movement of a vehicle door and a corresponding one Stop door of a traffic system according to the preamble of claim 1. It further relates to a device to carry out the procedure. Under traffic system is understood here in particular a local transport system, e.g. an S-Bahn, U-Bahn or H-Bahn system (people-mover).

With an automatic mass transit system with driverless Vehicle operation becomes both the vehicle and a platform secured a stop by means of doors. A change of passengers is therefore only possible if the vehicle is positioned such that vehicle door and corresponding Stop door face each other congruently. In order to achieve the shortest possible stay, open and close the doors as synchronously as possible.

Furthermore, one should avoid opening one of the doors, if their corresponding door from operational or system-related reasons, e.g. in the event of a malfunction or dispositive lock, is locked, and therefore not open may be. When realizing such conditions automatic control can be taken into account a connection by means of the given conditions Control cables between the vehicle and the stop door are not getting produced.

In a door control known from DE 29 10 260 A1 for Rail-bound vehicles are used to coordinate door movements a computer-controlled transmission device is used, based on the principle of wireless radio transmission based. there finds the coordination regarding corresponding doors serial instead. Because of the long transmission paths required through several computer levels of the transmission device the computing power of the participating computers is tied up. In addition, the communication time becomes undesirable Way limited so that the coordination of individual door movements is extremely complicated.

The features of the preamble of claims 1 and 4 are from DE 2910260 A. known.

The invention is therefore based on the object, a particular simple and safe functioning method for automatic Control of corresponding doors in a traffic system and a particularly suitable one for its implementation Specify device.

This object is achieved according to the method of the invention solved by the features of claim 1.

For coordinating movements of corresponding doors with each other every movement or a control signal defining a state directly between the Transfer doors. In other words: communication between corresponding doors do not find - as before - via a separate, common to all doors Transmission device, but directly from door to door corresponding door instead.

Because of the short distance and the direct optical Corresponding doors are connected Signal transmission between these doors is conveniently contactless and in the infrared range.

Each of the corresponding doors can become active and one Encourage opening or closing. This is done by sending a Activation signal of the control system of the requesting Door and receiving this signal from the control system of the corresponding door directly and by the shortest route between telegram traffic to the corresponding doors (handshake procedure) built up, which ensures a coordinated movement. Only then will each door move released when the activation signal from the control system the requested door has been acknowledged. By telegram traffic it is thus ensured that the doors move only takes place when both doors are neither disturbed, nor are blocked for operational reasons and therefore move allowed to.

In the open state, both corresponding ones monitor themselves Doors preferably mutually. This will be convenient a status signal confirming the corresponding position in the form of a life telegram between the corresponding Doors submitted. A receipt remains on such life telegram over a definable time period off, so at least one of the two corresponding ones Doors closed.

Regarding the device for automatic control of movements corresponding doors of a traffic system the stated object achieved by the features of claim 4.

The vehicle doors and the stop doors of the traffic system each have an independent local door control on all the necessary processes controls or regulates independently for the door movements. The higher-level control systems in the form of control computers for all vehicle doors on the one hand and for all stop doors on the other hand only give orders. The local ones Door controls are used to control a coordinated Movement of vehicle door and corresponding stop door used.

A signal is advantageously transmitted via a optical transmission channel directly and by the shortest route between the corresponding doors. The optical Scattering of the transmission channel, i.e. the beam angle or the spreading range, corresponding to an achievable or necessary positioning accuracy for the detection of corresponding Doors are used. This is convenient every vehicle door and every stop door Assigned transmission element that with the first or with is connected to the second control system.

Each transmission element in turn has a transmission sensor on the inside of the the opposite position the corresponding door defining scattering area is. Transmission sensors outside the scattering range thus no longer belong to the corresponding ones Doors. The latter therefore do not need a connection among themselves. Thus, such a data connection only corresponding doors Coordinate movements with each other.

The entire transmission system is conveniently for Transmission of signals designed in the infrared range. The Control systems and the transmission system with the respective Transmission elements of the doors are advantageous modular. Modularization therefore enables Training of standard components, which is a particular advantage is.

In the following, an embodiment is shown with reference to a drawing described the invention. The figure shows schematically Components of a traffic system with an automatic Control for coordinating the corresponding vehicle and Stops doors.

The traffic system 1 is, for example, a local traffic system with driverless operation of one in the position shown Vehicle 3 stopped at a stop 2. Vehicle 3 is guided on a line conductor 4. It points on both sides Vehicle doors 5, 6 and 7, 8 open. In this position the Vehicle 3 are only the vehicle doors 7 and 8 corresponding Stop doors 9 and 10 directly and immediately across from. Further stop doors 11 and 12 are shown for completeness only.

Each vehicle door 5 to 7 are a separate transmission element and assigned its own door control, whereby only the transmission elements 13, 14 and the door controls 13a and 14a of the vehicle doors 7 and 8 are shown. The Transmission elements 13 and 14 are via the door controls 13a, 14a with a common to all vehicle doors 5 to 8 first control system 15 in the form of a control computer connected. The transmission elements 13, 14 and the door controls 13a or 14a each form a modular one or together Component, which is also the first control system 15 of the Vehicle 3 can be assigned. This is advantageous trained as a standard component for any Application of such transport systems can be used may involve moving vehicle doors at the same time 5 to 8 and stop doors 9 to 12 required or requested is.

Similarly, each stop door 9 to 12 are a separate transmission element 16, 17, 18, 19 and its own door control 16a, 17a, 18a and 19a assigned. The transmission elements 16 to 19 are with the door controls 16a to 19a all stop doors 9 to 12 common second control system 20, also in the form of a control computer, connected. The transmission elements 16 to 19 and the door controls 16a to 19a and optionally the second Control system 20 of stop 2 also form one modular component.

The transmission elements 13 and 14 of the vehicle doors 7 and 8 each have a transmission sensor 21 or 22. Corresponding have the transmission elements 16 to 19 of the station doors 9 to 12 each have a transmission sensor 23 to 26 on. In this position of the vehicle 3 relative to Stop 2 form the transmission elements 13 and 16 of the corresponding doors 7 and 9 a transmission system. The same applies to the transmission elements 14 and 17 of the corresponding doors 8 and 10 within the overall system.

The door controls 13a, 14a and 16a to 19a control and regulate all for the movement of the respective door 5 to 8 or 9 up to 12 necessary or required processes independently. Only status messages are sent to the control systems 15 and 20 sent, and it will only be from there receive commands affecting the entire system. Due to required Force and displacement sensors and the control is it is therefore particularly advantageous to have each door 5 to 12 its own assign local door control 13a, 14a, 16a to 19a.

The signal transmission for a coordinated movement of the Corresponding doors 7 and 9 as well as 8 and 10 are made directly and by the shortest route between the transmission elements 13 and 16 and 14 and 17 via an optical transmission channel. This is indicated by the arrows 27 and 28. All for the coordinated movements of the vehicle doors 7, 8 and the corresponding stop doors 9 and 10 required Processes are controlled by the respective control system 15, 20 coordinates and from the respective door controls 13a, 16a and 14a, 17a independently controlled and regulated. It is in the Principle of the arrangement that only such doors 7, 9 and 8, 10th are allowed to coordinate their movements with each other - apart from a certain positioning accuracy and without Movement - directly opposite. This coordination of Processes are based on the corresponding doors 7 and 9 described in more detail.

Both corresponding doors 7 and 9 can become active and encourage opening or closing. It runs between the doors 7 and 9 via the transmission elements 13 and 16 and via the door controls 13a and 16a connected to them a telegram traffic from the transmission channel 27 in Form of signals is maintained. By telegram traffic ensures that movements only take place if both doors 7 and 9 are neither locked nor disturbed and are allowed to move. The transfer of information between doors 7 and 9 is wireless and due the short distance as well as the direct and unimpaired optical connection preferably in the infrared range, for which the transmission system must therefore be designed.

All movement commands or commands are from the control systems 15 and 20 coordinated and from the transmission systems 13 or 16 performed. As soon as one of the doors 7, 9 from its control system 15, 20 via a data line 29 or 30 receives a corresponding command, is between the corresponding activation systems 13 and 16 transmitted, and there is a telegram traffic built up. This is one of the requesting door 7, 9 the request telegram sent the optical transmission channel 27 from the transmission system 16, 13 of the requested Door 9, 7 acknowledged, the acknowledgment again from the requesting door 7, 9 is monitored.

The vehicle door 7 is to explain the control logic prompting door. Then the stop door 9 is corresponding Door if the vehicle 3 at stop 2 accordingly is positioned. If the requested door is not corresponding door 9, or is the controller or the Monitoring of the corresponding door 9 is disturbed no acknowledgment telegram sent. As a result, none Door movement. Can or may the corresponding door 9 not move, a negative acknowledgment is given and it is done also no door movement. In contrast, there is a positive acknowledgment when the corresponding door 9 moves can, may move and the movement has already begun Has.

In the open state, the two corresponding ones monitor each other Doors 7 and 9 constantly confirming this position Status signals in the form of so-called life telegrams. If there is no receipt for such a life telegram, then first the corresponding door 7, 9 and then or at the same time the other door 9, 7 is closed.

An important advantage of this device is the direct one and easy transmission path between the corresponding Doors 7, 9. The tasks of direct local coordination is from the higher-level control systems 15, 20 to the directly affected components, i.e. to the door controls 13a, 16a and from there to the transmission elements 13, 16 and Transmission sensors 21, 23 and doors 7 and 9 delegated. This results in standard components or modules, in particular the control systems 15, 20, the transmission elements 13, 14, 16 to 19, the door controls 13a, 14a, 16a to 19a and doors 5 to 12. Due to the modular structure is during commissioning and / or at a later troubleshooting made a special simplification.
