Abstract
A data capture system (1) has modular amplifier circuits (10) connected to modular capture circuits (11) within a rotor 2. Each capture circuit (11) has an FPGA (26) operation according to low-frequency and high-frequency state machines (M1, M2) to control ADCs (25) and upload from memories (30) to a host (15) During sampling, each FPGA (26) runs through a ready mode, a sampling mode, and again a ready mode according to a host command.
Claims17
A data capture system for interfacing with transducers and for transferring data to an external host system, said data capture system comprising a support for mounting within a rotor symmetrically about the rotor axis, said data capture system comprising a plurality of physically separate circuits, each being of elongate shape, each said circuit comprising:
- analog to digital converters for converting transducer analog signals to digital data;
- a memory;
- a host interface for communication of data with an external host system;
- and
- a data processor for receiving data from the analog to digital converters, for writing said data to the memory and for controlling upload of data from the memory to an external host system and for receiving control commands via said host interface.
