Data Acquisition
involves acquisition of signals and waveforms and processing the signals to
obtain desired information. The components of data acquisition systems include
appropriate sensors that convert any measurement parameter to an electrical
signal, which is acquired by data acquisition hardware.
With application software we can process and produce the
analog and digital data, then quickly save, report, and display the data either
onto the local computer or distributed system.
PC-based data acquisition products offer analog input, analog output, digital I/O, or a combination of these capabilities in a board, card, or module that is designed to interface with a personal computer.
Prior to the advent of the personal computer, data acquisition systems were products designed for just data acquisition and generally for a limited or specific application. These systems lacked the computational power and flexibility of today’s PC-based data acquisition systems.
By combining the computational power of the PC with one or more data acquisition boards, cards, or modules, a powerful system can be created. The combination of these two elements is so powerful, that today, they have replaced older systems that cost tens of thousands of dollars.
PC-based data acquisition products have been designed for every common PC bus configuration including: PCI, USB, PC/104, ISA, and PCMCIA
A PC-based data acquisition system can convert analog signals into a digital output form, which can be manipulated with software. Using software in conjunction with a personal computer, analog data can be displayed, logged, charted, graphed, or stored in memory as needed.
Stored data can later be used and compared with a set of established limits. Control decisions are made if the stored data is at the limit, above or below the limit. With repetitive measurements made by a PC-based data acquisition system, continuous monitoring and control can be performed.
