Definitions
- a counting system for a rail vehicle is specified.
- a rail vehicle is specified with such a counting system.
- a use of such a counting system is specified, as well as a method for determining a number of at least one predetermined object in a rail vehicle, for example a number of bicycles, a number of wheelchairs, a number of children's carriages or other objects that are in particular not living beings .
- a counting system for a rail vehicle has an induction loop.
- the counting system has a counting device.
- the counting system has a control device.
- the induction loop is signal-connected to the control device.
- the counting device is coupled to the control device in terms of signals.
- the control device is set up to determine the number of at least one predetermined object that crosses the induction loop as a function of a first signal from the induction loop and as a function of a second signal from the counting device.
- the specified object which in particular at least partially consists of a metal, is, for example, a bicycle, a wheelchair and / or a stroller.
- Other objects can also be specified, for example very large suitcases, rollers and other comparatively large objects that can be transported in a rail vehicle.
- the counting system's induction loop enables precise determination of the crossing of the object.
- the induction loop acts as a coil and is part of an oscillating circuit, for example. If the predetermined, at least partially metallic object reaches the area of the induction loop, at least the inductance of the induction loop is changed. This can be precisely determined by the control device.
- the counting device which is designed, for example, to be at least partially software-based, enables the object, in particular a class of the object, to be recognized.
- the counting device makes it possible to determine whether an object that has crossed the induction loop is one of the specified objects or not.
- the counting device also enables different predefined objects to be distinguished from one another. If, for example, bicycles and wheelchairs are to be counted, a crossing of the induction loop can be determined by means of the induction loop and a distinction between the objects can be carried out using the counting device.
- the control device has, for example, electronic components such as processors and memories. In the memory, for example, process steps are stored in a software-based manner, which enable the two signals from the induction loop and the counting device to be evaluated.
- the counting system thus enables a reliable counting of different objects such as bicycles and wheelchairs and a reliable differentiation of the individual objects.
- the data from the counting system is used, for example, to record how a rail vehicle is used by cyclists and / or wheelchair users.
- the utilization and / or availability of bicycle parking spaces and / or wheelchair spaces can be determined by means of the counting system and, for example, can be displayed for passengers.
- the induction loop reliably detects bicycles, wheelchairs and other objects. However, a distinction is not easily possible.
- the first signal of the induction loop is therefore combined with the second signal of the counting device in a temporal correlation.
- the counting device is already present in the rail vehicle in order to count people.
- the induction loop is now also available so that the specified object can be counted reliably.
- the counting device classifies or differentiates the objects that cross the induction loop.
- the induction loop counts the objects.
- the accuracy of the determination of the number of objects is thus significantly increased compared to using only the counting device and / or only the induction loop.
- the control device is set up to determine a direction in which the object crosses the induction loop. It is thus possible to determine in particular whether the object has entered or entered the rail vehicle, or exits or exits the rail vehicle.
- the direction is determined as a function of the second signal from the counting device.
- a single induction loop does not allow a precise determination of whether the object is being moved into or out of the train. This information is determined in particular by means of the counting device.
- the counting device is set up to determine the direction in which the object crosses the induction loop. For example, this information is then transmitted from the counting device to the Steuervor direction.
- the counting system has a second induction loop.
- the second induction loop is arranged next to the induction loop.
- the control device is set up to determine the direction in which the object crosses the induction loop as a function of the third signal from the second induction loop.
- the counting device has a measuring system for measuring the transit time of a light pulse. For example, a so-called time of flight method (TOF) is used. A light pulse illuminates the area of the induction loop during operation. The time it takes for the light to get to the object and back again is determined for each pixel. Different distances can thus be determined. Thus, for example, a size of the object can also be estimated.
- TOF time of flight method
- the counting system has a camera.
- the camera is used to record the reflection of the light pulse.
- the camera is an infrared camera or a conventional camera. From the images or a video signal from the camera, image processing is used to determine the object and classify it in a software-based manner.
- the counting device has a stereo camera.
- the stereo camera enables the size of objects to be determined and a direction determination by means of image processing of the video signal of the stereo camera.
- the induction loop has at least one cable loop made of an electrically conductive cable.
- the cable loop can be arranged in a floor of the rail vehicle.
- the induction loop of the counting system can be easily and space-savingly integrated into the rail vehicle.
- a rail vehicle has a counting system described here according to at least one embodiment.
- the rail vehicle thus enables a number of predetermined objects in the rail vehicle or which are moved into or out of the rail vehicle to be determined simply and reliably.
- the induction loop is arranged in a floor of a door area of the rail vehicle.
- a signal from the induction loop can be assigned as reliably as possible to moving into the rail vehicle and moving out of the rail vehicle.
- a counting system described here is used according to at least one embodiment to determine the number of objects that get into the rail vehicle.
- the counting system is also used to determine the number of objects that leave the rail vehicle.
- the number of the specified object that is located in the rail vehicle can in turn be determined from the two determined numbers.
- a method for determining a number of at least one predetermined object in a rail vehicle comprises determining a first signal of an induction loop.
- the first signal is representative of crossing the object via the induction loop.
- a second signal from a counting device is averaged.
- the second signal is representative of a class of the object.
- the number of the object is determined as a function of the first and the second signal. The combination of the two signals to determine the number enables a precise determination of the number and a reliable distinction between different objects.
- a direction of crossing the induction loop is determined as a function of the second signal. It is thus reliably determined whether the object is moving into or out of the rail vehicle.
- a third signal from a second induction loop is determined.
- the third signal is representative of a crossing of the object via the second induction loop.
- a direction of crossing the induction loop is determined as a function of the first signal and the third signal.
- the direction can be determined. This enables reliable determination of whether the object is being moved into the rail vehicle or is being moved out of the rail vehicle.
- the second signal is determined by means of a camera.
- the camera is, for example, a stereo camera.
- Other methods for determining the second signal are also possible, which are carried out in software-based, in particular, by means of image processing.
- a number of bicycles that cross the induction loop is determined.
- a number of wheelchairs that cross the induction loop is determined.
- a number of prams that cross the induction loop is determined. It is also possible to determine those specified objects, for example a Determine a number of suitcases that are larger than a given size.
- the method is used, for example, to operate a counting system described here.
- the features, advantages and developments of the counting system therefore also apply to the method and vice versa.
- Figure 1 shows a schematic representation of a rail vehicle
- Figure 2 shows a schematic representation of a counting system according to an embodiment
- FIG. 3 shows a flow chart of a method for rail vehicles described here
- Figure 4 shows a schematic representation of a counting system according to an embodiment.
- FIG. 200 An exemplary embodiment of a rail vehicle 200 is shown schematically in FIG.
- the rail vehicle 200 is, for example, a train for transporting passengers.
- the rail vehicle has a door 203.
- the door 203 is arranged in a door area 202.
- the door area 202 is in particular the area of the rail vehicle 200 which directly adjoins the door 203.
- the rail vehicle 200 has a counting system 100.
- Figure 2 shows schematically the counting system 100 according to an exemplary embodiment.
- An induction loop 101 is arranged in the door area 202 in a floor 201 of the rail vehicle 200.
- the induction loop 101 can also be arranged in other places in the door area 202, for example in a side or a ceiling. In the floor 201, however, it is advantageous because here, for example, the smallest distance to an object 104 to be counted can be achieved.
- the counting system 100 also has a counting device 102.
- the counting device 102 has a measuring system 108, for example.
- the counting device 102 has a camera 110.
- the camera 110 is part of the measuring system 108.
- the counting device 102 has a stereo camera 111.
- Different combinations of the measuring system 108, the camera 110 and the stereo camera 111 are possible.
- the counting device 102 has a control device 103.
- the induction loop 101 and the counting device 102 are each connected to the control device 103 for signaling purposes.
- the control device 103 is designed to perform object recognition of the object 104 as a function of signals from the induction loop 101 and the counter 102 and to count the number of objects that cross the induction loop 101.
- the counting device 102 is, for example, a counting device that is used for counting people in the rail vehicle 200.
- the object 104 can be classified as a function of a signal, for example the stereo camera 111.
- the This means that the actual object 104 can be assigned to an object class stored in the control device 103, for example the bicycle class, the wheelchair class or the stroller class. Other objects and object classes are also possible.
- the counting device 102 is assigned to the door area 202 for this purpose.
- a field of view of the stereo camera 111 is directed towards the door area 202.
- a viewing area of the counting device 102 is aligned in such a way that it corresponds to the position of the induction loop 101.
- a signal from the induction loop 101 can thus be assigned to information from the counting device 102.
- the number of objects 104 that are moved into rail vehicle 200 can be reliably determined by means of the induction loop.
- the number of a further object 114 that is moved out of the rail vehicle 200 can be reliably determined.
- the object 104 is thus moved in a direction 105, from outside the rail vehicle 200 via the induction loop 101 into the rail vehicle 200.
- the object 114 is moved in an opposite direction 106, that is to say from an interior of the rail vehicle 200 via the induction loop 101 to the outside of the rail vehicle 200.
- the induction loop 101 When crossing the at least partially metallic object 104, 114, a corresponding de signal is transmitted to the control device 103 by the induction loop 101.
- the induction loop 101 has, for example, a cable loop 112 or a multiplicity of cable loops 112 made of an electrically conductive cable 113.
- the induction loop 101 thus acts as a coil.
- the type or class of the object 104, 114 cannot be determined with sufficient precision by means of the induction loop 101 alone. Therefore, the information from the counting device 102 is also evaluated in the control device 103. tet. Using image processing, image recognition or other optical methods, it is determined in the door area 202 whether a recognized object corresponds to a predetermined object 104, 114. This is also possible, for example, by means of the measuring system 108, which emits a light pulse 109. The object 104, 114 is then determined and classified by means of the light pulse 109 using a so-called transit time method. In addition, the signal from the counting device 102 can be used to determine a direction in which the object 104, 114 is moved, i.e. in particular the directions 104, 106 Rail vehicle 200 is moved into or out of the rail vehicle 200.
- the counting system 100 thus combines the counting process by means of the induction loop 101 with the counting process of the counting device 102.
- This enables precise differentiation and counting of the objects 104, 114 depending on whether they enter the rail vehicle 200 or leave the rail vehicle 200.
- a number of objects 104, 114 that are located in rail vehicle 200 can then also be determined from these two values, in particular a difference between them.
- This can be displayed to travelers in the rail vehicle 200 or outside on the rail vehicle 200, for example.
- the utilization or availability of bicycle parking spaces and wheelchair spaces for example, can be displayed. It is also possible to record how the rail vehicle 200 is used by cyclists, wheelchair users and, for example, families with prams.
- the object 104, 114 is determined by means of the induction loop 101, such as induction loops, for example, used to control traffic lights in road traffic. It is therefore not necessary to train the counting device 102 in a complex and thorough manner so that it can classify and count the objects with sufficient precision on its own. Such training is time-consuming and takes several months, for example. In addition, the training only works for special specific deployment environments. If the operating environment changes, the training has to be repeated or the accuracy decreases again. This is avoided by combining the counting device 102 with the induction loop 101, which provides at least a time specification for when an object classification is to be carried out by means of the counting device 102.
- FIG. 3 shows a method for determining a number of the objects 104, 114 in the rail vehicle 200 according to an exemplary embodiment.
- a step 301 a first signal from the induction loop 101 is determined.
- the signal is representative of a crossing of the object 104 via the induction loop 101.
- a second signal from a counting device is determined which is representative of a class of the object 104.
- step 301 is carried out first and then step 302.
- Other sequences are also possible and they can also be carried out simultaneously.
- the presence of the object 104, 114 is precisely determined by means of step 301.
- a differentiation into individual classes is then possible.
- different predetermined objects 104, 114 can be precisely distinguished separately from one another and thus the number can be determined separately from one another.
- step 303 the number of objects 104, 114 is determined as a function of the results of steps 301 and 302. Subsequently, it is possible, for example, for the number of additional systems determined to be made available or to be displayed directly on a display.
- FIG. 4 shows the counting system 100 according to a further exemplary embodiment.
- the counting system 100 according to FIG. 4 essentially corresponds to the counting system 100 according to FIG. 2. In the following, therefore, differences are primarily dealt with.
- the counting system 100 additionally has a second induction loop 107.
- the second induction loop 107 is arranged next to the first induction loop 101 in the door area 202 in the floor 201 of the rail vehicle 200.
- it is possible to determine the direction 105, 106 by means of the two induction loops 101, 107, which are arranged one behind the other in particular along the directions 105, 106.
- the two induction loops 101, 107 make it possible to determine whether the object 104 is moving into the rail vehicle 200 or is being moved out of the rail vehicle 200.
