Data Acquisition Technologies

Aerospace engineers are embracing modern data acquisition (DAS) technology to meet a wide range of military, commercial, and general engineering, tracking, operational, and condition monitoring, as well as manufacturing. DAS by Acquiry has evolved to address changing requirements in all areas of engineering research. These demands have been reflected in the development of many new data acquisition technologies.

DAS is the acronym for direct access supervisory computer systems. These technologies, which include real-time data acquisition systems (RAS) and remote sensing data acquisition systems (RSAS), enable engineers to rapidly process large amounts of information quickly and convert the gathered information into valuable data sets that can be analyzed, maintained, stored, and/or marketed. RAS and RSAS are also collectively referred to as Data Acquisition System. DAS technologies are designed to facilitate the detection, identification, analysis, and the correction of mechanical, optical, electronic, or statistical problems in an efficient manner.

Data acquisition systems technologies are also commonly called “data collecting” technologies. Data collection technologies typically gather, process, store, analyze, manipulate, and distribute the collected information in a useful manner. In particular, Data Collection technologies help engineers conduct relevant tests and make relevant observations. It is also vital to the successful operation of any business. Today’s” Data Collection” technologies provide engineers with a valuable tool for analyzing and improving operations. The accuracy, control, reliability, storage space, speed, and low cost of a data acquisition system depend on the input from a business as well as its particular application.

Common data acquisition systems technologies include Communications Interface, Computer Interface, Management Interface, Digital Interface, Physical Interface, Telephone Interface, and Wireless Network Interface. Communications interface is an indispensable communication component to any data acquisition system. It controls the communications system of the equipment. Computer interface controls the computer architecture.

A Computer interface provides software applications with data capture, data extraction, input and output devices, and buffering application services. Computer interface or computer-to-computer (C2) connections are either direct or indirect. Direct connections are physical interfaces, while indirect connections are logical or electronic. Management interface controls or identifies a particular operating system and provides facilities such as memory management, firmware loading, control display, debugging facilities, and programming interfaces. Digital interface provides a standard format for communicating with external peripheral devices or operating systems. Optical interface controls the connection of an input device with an output device.

Data acquisition systems technologies help engineers in data gathering tasks by enabling easy accessibility of sample rates and speeds for various purposes. Sample rates and speeds must be properly recorded and must be accurately captured in a corresponding format. This helps engineers in decision making. They can now easily evaluate the signal characteristics of a signal or plot a data plot without having to go through the process of conversion from analog to digital or vice versa. It is also helpful in automation of the process of measurements.
