Definitions

  • the invention relates to a device and a method for active pressure control in a rail vehicle according to the preamble of claim 1.
  • Such a device and such a method for example, from the DE 102 08 006 A1 out.
  • the device presented there and the associated method set off to compensate for short-term internal pressure changes, which are due for example to the entrance to a tunnel, vehicle encounters or other short-term pressure surges.
  • the air conditioning system in a rail vehicle has to fulfill different tasks. These tasks include not only the treatment of supply air to set a comfortable indoor climate at different times of the year, but also the filtering of the outside air. In addition, the air conditioning system must ensure that a sufficient overpressure relative to the ambient pressure is set in the rail vehicle. As a sufficient overpressure 20Pa to 50Pa overpressure compared to the ambient pressure are considered. The provision of a corresponding overpressure is necessary in a rail vehicle in order to avoid that outside air which is not conditioned can leak into the interior due to leaks in the rail vehicle and thus impair passenger comfort.
  • the vehicle internal pressure in a rail vehicle depends to a significant degree on the tightness of the rail vehicle body.
  • the tightness of the rail vehicle body is in particular dependent on the quality of assembly in production, the adjustment of the outer doors, the number of drainage holes, as well as the quality and condition of the seals in the individual vehicles. It should be noted that as a rule the quality and the condition of the seals are not constant over a vehicle fleet.
  • the air conditioning system must maintain the vehicle's internal pressure throughout the life cycle of the rail vehicle, taking into account the different wear of each vehicle.
  • the exterior doors are often more or less evenly adjusted. This increases the wear of the seals, which can be leaking in the period of use until the next maintenance, whereby the internal pressure of the rail vehicle is uncontrollably impaired.
  • Object of the present invention is therefore to provide an apparatus and a method with which it is possible to ensure a constant internal pressure within the rail vehicle over the entire life cycle of the vehicle even with different tightness and variable wear of the seals.
  • an apparatus for actively controlling the vehicle internal pressure in a railway vehicle comprising a ventilation device for increasing the internal pressure in the rail vehicle, a ventilation device for reducing the internal pressure in the rail vehicle, a measuring device for measuring the internal pressure in the rail vehicle, which is characterized in that only the venting device for reducing the internal pressure is controllable by the control device as a function of the internal pressure determined by the measuring device and the measuring device measures the internal pressure at intervals of at least days.
  • a vent which is regulated as a function of the measured vehicle internal pressure in the rail vehicle, a maintenance of a desired overpressure in the vehicle interior is possible, even if the leakage, ie the outflow of air inside through leaks, is variable. If the leakiness of the rail vehicle increases, for example as a result of a change in the adjustment of the outer doors or due to wear of the seals, the pressure loss due to the leakages can be compensated by reducing the ventilation via the ventilation device. This allows under different operating conditions and wear conditions of the rail vehicle over the entire life cycle.
  • the control device has an input channel for initiating a diagnosis signal indicative of the open and / or closed state of an outer door and / or a window of the rail vehicle.
  • a diagnosis signal indicative of the open and / or closed state of an outer door and / or a window of the rail vehicle.
  • a ventilation device for example, an air conditioner of the rail vehicle, which sucks outside air, processed and in the Interior of the rail vehicle initiates. Through this introduction, an overpressure is built up in the interior of the rail vehicle.
  • a venting device is understood to mean, for example, an outboard valve, a venting flap or a fan (ventilator).
  • a measuring device for measuring the internal pressure in the rail vehicle for example, a pressure sensor or a pressure gauge.
  • the measuring device determines the internal pressure in the rail vehicle on the train and / or wagon plane. Both in the determination of the internal pressure at train level, as well as determination of the internal pressure on the car level, it may be provided according to the invention that a plurality of distributed in the train or wagon arranged measuring devices are used for determining the internal pressure in the rail vehicle. It may be provided that the internal pressure values determined by the individual measuring devices are combined to form an average internal pressure value. It can also be provided that a determination of the internal pressure takes place in sections within the rail vehicle.
  • the venting device is arranged in such a way that the occurrence of air currents affecting the passenger comfort within the areas of the rail vehicle used by passengers is avoided.
  • the venting devices are arranged in the ceiling area and / or in the floor area of the rail vehicle.
  • a plurality of ventilation devices in Rail vehicle are provided, which are arranged distributed so that the passenger comfort affecting air flows avoided or at least reduced.
  • the control of the venting takes place in the context of climate control of the rail vehicle.
  • the control device is integrated in the climate control device. This makes it possible to consider the ventilation device alternately, so that in addition to an increase in the discharged via the venting device from the rail vehicle amount of air through the ventilation system, the interior of the rail vehicle supplied amount of air is reduced.
  • the venting device has an external valve, a ventilation flap and / or a fan (fan) and the regulation of the internal pressure by means of opening or closing the external valve and / or the ventilation flap and / or by means of speed control of the fan.
  • a ventilation flap and / or a fan fan
  • a determination of the internal pressure takes place only during the closed outer door and / or closed window of the rail vehicle and in the case of stability, ie when the rail vehicle is stationary.
  • the state of the doors and / or windows of the rail vehicle is queried by the control device.
  • Such a query can be done for example by means of door and / or window sensors.
  • status information is retrieved from the train control system of the rail vehicle and taken into account. The travel speed signal in the train control system ensures that the internal pressure is only evaluated in the event of a stall.
  • a measurement of the internal pressure does not take place continuously during the entire driving operation, but at intervals, for example at intervals of minutes, hours, days or months.
  • a measurement of the internal pressure is only carried out within the framework of the maintenance intervals of the rail vehicle, for example in autumn or spring, and an adaptation of the venting performance to the ventilation performance within the scope of the corresponding inspection takes place.
  • FIG. 1 shows the schematic structure of a device for active pressure control in a rail vehicle 900.
  • the rail vehicle has a ventilation device 120, which may be formed for example by an air conditioner.
  • the ventilation system 120 supplies outside air to the interior of the rail vehicle 900, resulting in the inside of the Rail 900 builds an overpressure relative to the ambient pressure outside the rail vehicle 900.
  • a diagnostic signal 210 which indicates the open or closed state of the outer doors 910 and / or window 920 of the rail vehicle 900, is run on a control device 200.
  • a measured signal in the control device 200 representing the internal pressure in the rail vehicle 900 determined by means of the measuring device 160 passes through the measured value line 215. With the outer doors 910 and windows 920 closed, the control device 200 evaluates the signal of the measuring device 160.
  • the control device 200 activates via control lines 212, 213, 214 a venting device 141, 142, 143 via which the internal pressure can be adjusted according to the threshold value specification .
  • a venting device 141, 142, 143 via which the internal pressure can be adjusted according to the threshold value specification
  • an outer valve 141, a ventilation flap 142, a fan (fan) 143, or a combination of these ventilation devices may be arranged in the rail vehicle as venting device.
  • the venting devices 141, 142, 143 are arranged in such a way that airflows that adversely affect the passenger comfort within the area of the rail vehicle used by passengers do not come through the internal pressure escaping from the rail vehicle via these devices.
  • control device 200 sends control signals to the ventilation device 120 via a control line 211 in order to likewise regulate the ventilation device 120 as a function of the determined internal pressure in the rail vehicle 900.
  • the functions of the ventilating device 120 and the venting device 141, 142, 143 can thus be synchronized with one another.
