Fluid flow measurement device with distributed sensor architecture
The patent US12043407B2 describes a sophisticated measurement device designed for attachment to the surfaces of mobile or fixed objects situated in flow streams, such as aircraft. The device features a substrate that houses sensors within a cavity containing a flexible printed circuit. This circuit is organized with hierarchized buses, including two data communication buses at each end and an internal data acquisition bus. The data acquisition bus connects various control circuits, each linked to one of the communication buses, allowing for a distributed connection of sensors. These sensors are strategically positioned to transmit data to the surrounding control circuits, enhancing data collection efficiency.
Additionally, the patent outlines a comprehensive measurement system that integrates the measurement device with a central unit and at least one end device featuring line termination impedance. The system may include a loopback device and an extension device, which further expands the measurement capabilities by connecting additional sensors. The loopback bus facilitates communication between the measurement device and the extension device using an anisotropic conducting film. The method of measurement involves a structured approach where sensors relay data to designated primary and secondary control circuits, ensuring continuous data flow even if one circuit fails. This innovative design aims to improve the reliability and accuracy of measurements in dynamic environments, particularly in aerospace applications.
