Definitions
- the invention relates to a method for determining the Pressure tightness of a provided with a pressure compensation system High-speed rail vehicle where the internal pressure and the external pressure of the vehicle are observed become.
- High-speed rail vehicles like the passenger coaches of high-speed trains, but also magnetic levitation vehicles, must be hermetically pressure-tight. Especially on tunnel routes, but also during train encounters there are significant pressure fluctuations that the Affect the well-being of passengers.
- the car bodies and the fixtures like windows, entry doors, Wagon crossings and line bushings are therefore at such vehicles designed pressure-tight.
- the fresh air supply takes place via air conditioning systems, their exterior and Provide exhaust air ducts with pressure compensation systems are.
- the single car The car to be tested is at the crossings to the neighboring vehicle with bulkheads hermetically tightly closed. All existing openings will be sealed, the car is inflated with a compressor or vacuumed. If a fixed pressure difference to the environment is reached, the connecting line shut off and the compressor switched off. by virtue of existing leakages are compensated for Environment instead.
- the speed of pressure equalization represents a measure of the tightness of the car.
- EP 0 579 536 B1 ( DE 693 05 117 T2) describes a device in which the pressure tightness of a vehicle provided with pressure protection is quantified by comparing the internal pressure with a pressure inside a container located in the vehicle.
- a differential pressure detector also measures the external pressure to cause the air ducts to be left out, but there is no further analysis of the course of the control or manipulated variable of the system.
- the invention has for its object a method to create a level of pressure tightness of a rail vehicle in operation.
- this object is achieved by observation of a malfunction occurring while driving of the external pressure occurring when the pressure protection system is activated Course of at least one control or manipulated variable of the pressure protection system and analyzing the course the control or manipulated variable of the pressure protection system taking into account the disturbance causing it of external pressure.
- the at least one control or manipulated variable is preferred the observed internal pressure or the manipulated variable of the system (both sizes are used regularly Find).
- the pressure disturbance can be retracting or extending in or out of a tunnel or else it can be to act as a train encounter.
- the train is with at least one device that the inventive method uses, equipped, but is advantageous Equipment of every single car.
- the invention is based on the idea that the course the control and manipulated variables of the pressure protection system of a high-speed rail vehicle at one Pressure disturbance, as occurs in normal operation, is known.
- the "effort" of the regulated pressure compensation system to maintain an essentially constant internal pressure is too high or the pressure compensation system the internal pressure is not good enough keep constant there is a leak.
- the method is used so that constantly the pressure tightness of the vehicle (as both the individual unit, as well as the entire association) Characteristics are determined and recorded. These parameters are then evaluated statistically.
