Title: TOPDAQ Acquisition Utility Beta version 1.0

Software ·
OSTI ID:1231304

This TOPDAQ Acquisition Utility uses 5 digital cameras mounted on a vertical pole, maintained in a vertical position using sensors and actuators, to take photographs of an RP-2 or RP-3 module, one camera for each row (4) and one in the center for driving, when the module is at 0 degrees, or facing the eastern horizon. These photographs and other data collected at the same time the pictures are taken are analyzed by the TOPAAP Analysis Utility. The TOPCAT implemented by the TOPDAQ Acquisition Utility and TOPAAP Analysis Utility programs optimizes the alignment of each RP in a module on a parabolic trough solar collector array (SCA) to maximize the amount of solar energy intercepted by the solar receiver. The camera fixture and related hardware are mounted on a pickup truck and driven between rows in a parabolic trough solar power plant. An ultrasonic distance meter is used to maintain the correct distance between the cameras and the RP module. Along with the two leveling actuators, a third actuator is used to maintain a proper relative vertical position between the cameras and the RP module. The TOPDAQ Acquisition Utility facilitates file management by keeping track of which RP module data is being taken and also controls the exposure levels for each camera to maintain a high contract ratio in the photograph even as the available daylight changes throughout the day. The theoretical TOPCAT hardware and software support the current industry standard RP-2 and RP-3 module geometries.
