Definitions

  • the present approach relates to a housing for a surveillance system, a surveillance system and a cooling arrangement for a housing of a surveillance system, for example in the form of a traffic surveillance system.
  • Monitoring systems that are used for traffic monitoring for example, have an air conditioner.

  • US 20170013741 A1 describes a housing for a radar sensor.
  • an air conditioning system can be dispensed with in a monitoring system if an air flow flowing along a side wall of a housing provided for the monitoring system is deflected. Self-cooling is thus possible.
  • the proposed arrangement and method allows for inexpensive and efficient cooling of built-in electronic components. Additional use of an electric cooler/fan can be avoided.
  • a housing for a surveillance system for monitoring an area surrounding the surveillance system has the following features: a first side wall with a front side and a rear side, a second side wall opposite the first side wall with a front side and a back and a ceiling connecting the first side wall and the second side wall; and a guide device that is designed to deflect an air flow flowing along at least one of the side walls at an angle of at least 45°, in particular at right angles, and/or to direct it between the front and the back of the at least one side wall.
  • the monitoring system can be a traffic monitoring system or a monitoring system for monitoring an object, for example a building, or an area, for example a square or path.
  • the housing may be shaped to house electronic components of the surveillance system.
  • the housing can have an opening or a viewing pane for a sensor system of the monitoring system on the front side and additionally or alternatively on the rear side.
  • the ceiling can form an upper closure of the housing.
  • the air flow can be used to temper the housing and thus also components that can be arranged inside the housing, for example for cooling.
  • the guide device enables, for example, an air flow that is flowing vertically during operation of the monitoring system to be deflected into a horizontally flowing air flow.
  • the air guiding device is shaped to deflect the air flow at an angle of at least 45° and at most 135° or at an angle of at least 80° and at most 100° or at an angle of 90°.
  • the air flow can be a flow caused by natural convection.
  • the guiding device enables, for example, a horizontally flowing air stream to be passed through, which can be caused, for example, by wind hitting the housing.
  • the air flow can be a purely natural air flow generated without using a drive, for example a fan.
  • the housing can act at least one air duct for conducting an air flow caused by temperature differences or pressure differences. The temperature differences can be caused, for example, by solar radiation or waste heat.
  • the pressure differences can be caused, for example, by pressure fluctuations in the atmosphere surrounding the monitoring system. Only optionally can the air flow be an at least partially forced air flow, for example using a fan.
  • the side walls can be identical or different, for example mirror-symmetrical, be formed. Both side walls or only one of the side walls can be shaped to guide the or different air currents.
  • the guiding device can be designed to divert an air flow flowing in the direction of the ceiling into an air flow flowing towards the front and/or the rear of the at least one side wall.
  • a diversion lends itself to an air flow caused by convection.
  • no fan is required to effect and/or deflect the air flow.
  • Such a cooling arrangement in the housing for example of a traffic surveillance system, with a substantially right-angled airflow deflection, for example from a lower housing part to an upper housing part, can optionally be designed with the support of an electric fan and/or blower.
  • the at least one side wall can have an opening for the air flow on the front side and additionally or alternatively on the back side. This enables the air flow to be guided inside the housing or inside the at least one side wall. If an opening is provided only in the front or only in the back, it can be used as an outlet for airflow caused by convection. If an opening is provided both on the front and on the rear, these can be used additionally or alternatively for passing wind as at least a portion of the air flow. An opening can be designed as a slot. A plurality of openings can also be provided, which can be distributed over the front side and additionally or alternatively over the rear side of the at least one side wall.
  • the at least one side wall can be double-walled to guide the air flow along opposite inner sides of the side wall.
  • the guide device can thus be arranged on at least one of the inner sides.
  • the air flow or multiple air flows can be directed inside the at least one side wall.
  • the air flow can be guided and, if necessary, directed in the interior of a side wall.
  • the double-walled side wall can also make it more difficult for an interior space enclosed by the housing to heat up caused by solar radiation. Instead, solar radiation acting on the outer wall can be used to drive the airflow flowing inside the side wall.
  • the ceiling should be double-walled.
  • Such a double wall of the housing or a housing upper part enables radial air distribution. Without a double wall, the air flow can be guided along an outside or inside of the corresponding single-walled side wall or side walls using the guide device.
  • the guiding device can have at least one rib connected to the at least one side wall.
  • a rib is very easy and inexpensive to implement. Appropriate positioning and orientation of the rib allows the air flow to be deflected in a manner suitable for cooling. If the side wall is formed as a double wall, the rib can connect the inner and outer walls of the side wall. As a result, the stability of the housing can also be increased.
  • the guiding device can comprise a plurality of ribs connected to the at least one side wall.
  • the ribs can be arranged on one of the side walls or distributed over both side walls.
  • a plurality of separate air flows can be glided through the plurality of ribs or, for example, an air flow on the inlet side can be divided into a number of air flows on the outlet side.
  • At least one rib may be continuous between the front and back of the at least one sidewall.
  • Such a through rib is suitable, for example, as a fluid-tight seal between the at least one side wall and the cover.
  • At least one rib can only partially run between the front and the back of the at least one side wall.
  • Such a short rib can, for example, have a length that is less than a third of a distance between the front side and the back side of the at least one side wall.
  • the short rib can be used to deflect only part of the airflow.
  • at least two short ribs can be arranged at a distance from one another in one plane, so that part of the air flow can flow through vertically between the short ribs arranged adjacent in one plane.
  • such an arrangement is additionally or alternatively suitable for guiding a horizontal air flow.
  • the housing can be formed in the shape of a ring.
  • the housing can be cylindrical and oval in shape.
  • the ceiling and the side walls and optionally a floor can flow into one another.
  • the housing in particular the upper part of the housing, can be formed in one piece.
  • the advantages of being in one piece are weight savings, strength (stiffness), functional integration with considerable material savings and significantly lower production costs during assembly.
  • the housing can enclose an interior space.
  • the housing can be shaped in order to be closed at the front and/or at the back with a cover, for example a disk or a lid, in order to close off the interior space.
  • a corresponding cover can be part of the housing.
  • a corresponding cover can have one or more passage openings, for example for a lens of a sensor system of the monitoring system.
  • the front side and additionally or alternatively the back side of at least one of the side walls can have a bevel. This enables an improved entry and additionally or alternatively exit of the air flow.
  • the at least one side wall can have an opening for the air flow on an underside opposite the ceiling.
  • the housing can have a base which is opposite the cover and connects the first side wall and the second side wall and has an opening for the air flow. In this way, air can flow into the housing from below when the monitoring system is in operation.

  • the image capturing device can be a camera, for example.
  • the sensor for speed measurement can be designed, for example, to measure a speed of an object located in the detection range of the monitoring device using radar beams.
  • the housing can thus be used in connection with known monitoring systems.
  • the monitoring system can be implemented without a fan for promoting the air flow. This enables a cost-effective and low-maintenance implementation. In addition, no installation space needs to be kept free for a fan.
  • the monitoring system can be designed with a fan to promote the air flow.
