Abstract
Display assemblies with enhanced fan control are disclosed. An electronic display is located within a housing. A controller receives readings from sensors located at an airflow pathway extending within the housing and determines which of the readings is, relatively, furthest from a predetermined, associated parameter. The controller drives fans located at the airflow pathway based on the relatively furthest one of the readings in accordance with a control scheme including reading-dependent, preprogrammed operating parameters for the fans.
Claims20
A display assembly with enhanced fan control, said display assembly comprising:
- a housing;
- an electronic display located within the housing;
- an airflow pathway extending within the housing;
- fans located at said airflow pathway;
- sensors located at said airflow pathway;
- and
- a controller in electronic connection with said one or more sensors and said one or more fans, said controller comprising one or more electronic storage devices comprising software instructions, which when executed, configure one or more processors to:
- receive a reading from each of said sensors;
- determine which of the readings is, relatively, furthest from a predetermined, associated parameter;
- and
- drive said fans based on the relatively furthest one of said readings in accordance with a control scheme comprising one or more reading-dependent, preprogrammed operating parameters for said fans.
8 more elements
A display assembly with enhanced fan control, said display assembly comprising:
- a housing comprising an intake and an exhaust, each open to an ambient environment;
- an electronic display layer located within the housing;
- a cover positioned forward of said electronic display layer;
- an illumination device positioned rearward of the electronic display layer to illuminate the electronic display layer when powered;
- a first airflow pathway extending within the housing between said intake and said exhaust to form an open airflow pathway;
- a second airflow pathway extending entirely within said housing to form a closed, continuous airflow pathway;
- fans comprising a first set of one or more fans located at said first airflow pathway and a second set of one or more fans located at said second airflow pathway;
- sensors comprising a first set of one or more sensors located at said first airflow pathway and a second set of one or more sensors located at said second airflow pathway;
- and
- a controller in electronic connection with said sensors and said fans, said controller comprising one or more electronic storage devices comprising software instructions, which when executed, configure one or more processors to:
- establish zones within said display assembly, including at least a first zone located at the first airflow pathway and a second zone located at the second airflow pathway, wherein at least one of said first set of one or more sensors and at least one of said first set of one or more fans is located within the first zone and at least one of the second set of one or more sensors and at least one of said second set of one or more fans is located within the second zone;
- establish an acceptable operating parameter for each of said sensors, wherein said operating parameters are different between said zones;
- establish a control scheme for each of said fans, wherein said control scheme comprises fan speed levels which vary relative to a difference between a reading from a respective subset of one of said sensors and a respective one of the operating parameters associated with the respective subset of one of said sensors, and wherein said control scheme is different between said zones;
- receive the readings from said sensors;
- determine which of said readings is, relatively, furthest from the associated operating parameter for the respective sensor, on a zone-by-zone basis;
- and
- drive each of said fans based on the relatively furthest one of said readings on a zone-by-zone basis.
