摘要:
A personal environmental module for controlling the environment in a work space, the module including a housing having an air inlet and a pair of air outlets, a pair of dampers mounted in the air inlet, one of the dampers being connected to a preconditioned air source, the other damper being connected to room air, a pair of fans mounted in the housing in a position to allow air through the dampers, a controller for controlling the speed of the fans and the amount of air flowing through the dampers and a control panel operatively connected to the controller for setting the speed of the fan and the temperature of the air discharged through the outlets. A baffle is provided in the housing to direct a portion of the air from each fan into the air flowing from the other fan in order to mix preconditioned air with the room air. An electrostatic filter and white noise generator can be mounted in the housing and a light sensor and occupant sensor operatively connected to the controller.
摘要:
A control system includes a plurality of sensors configured to produce a plurality of sensor signals in response to a sensed condition; a plurality of controllers configured to produce a plurality of control signals in response to one or more sensor signals; a plurality of operational units, each respective operational unit receiving one or more control signals, each respective operational unit configured to produce a control effect in response to the one or more control signals; and a display device which produces a starfield display in response to the plurality of sensor signals and the plurality of control signals. The starfield display conveys operational information about the control system to an operator.
摘要:
The operational state of a complex control system, with a number of operating units controlled by a plurality of sensing and input devices, can be dynamically displayed as a starfield. In the starfield, each operating unit is depicted by a separate cluster of stars representing the states of the sensing devices for that operating unit. The position and other display attributes of the stars denote the functional state of the associated device. An archive of starfields is maintained in a storage device with each such starfield depicting the state of the control system for a particular operating condition, such as a specific system error. When an unusual starfield occurs, it can be compared to the archived starfields to determine whether a problem exists and if so determine a solution.
