Definitions

  • Claim 5 relates to a device for monitoring underground systems, in which the measuring plane is arranged transversely to the direction of flow of the air.
  • the following claims 6 and 7 relate to certain arrangements of detectors within a measurement plane.
  • the new procedure meets the requirement that an impermissible change in the physical or chemical properties of the air within the underground system must be detected as quickly as possible and precisely localized.
  • the type of detection is irrelevant.
  • the detector (s) closest to the cause of the change will make the decisive contribution to triggering an alarm signal to the sum signal determined integratively over the entire level.
  • Even higher wind speeds have no significant influence on the detection, since the detectors are not only arranged on the ceiling, but also in the area of the walls and floor of the building.
  • the invention has the advantage that, in the case of the installation of individual detectors, relatively insensitive and therefore inexpensive detectors, for example optical detectors, which only deliver a signal when a certain status is reached, can be used.
  • the decisive factor is that the air-pollutant gas mixture reaching the evaluation device is recognized by the latter as exceeding the threshold value.
  • the arrangement of suction nozzles in the area of the floor of the underground system means that it is also possible to detect harmful gases whose density is greater than air. Since the set threshold value is only exceeded if several suction nozzles suck in a harmful gas over a longer period of time or, in the event of a fire, flue gas is sucked in quickly from several nozzles, ie a quantitative increase in the harmful gases is suddenly detected, there is a reliable distinction between dangerous and only due to increased traffic or standing traffic caused air changes possible.
  • a locally high, but locally and temporally limited concentration of exhaust gases from motor vehicles registered by only one or two detectors reaches the set integral
  • a further increase in security in underground systems is possible if sensors measuring different properties are installed within a measurement level or, for example, optical or thermal detectors are installed in addition to suction nozzles. This is possible due to the use of inexpensive, less susceptible and low-maintenance detectors with an economically justifiable effort.
