Remote DAQ (data acquisition) is simple
acquiring data from a remote location, in most cases remote from a personal
computer. Sometimes remote DAQ can be not only 100s to 1000s of feet from a
personal computer, but also many miles away.
For remote DAQ applications at a "wired" location distant from where the PC is located, Ethernet data acquisition devices represent a good solution. Ethernet data acquisition devices plug into an Ethernet network and can then be configured from anywhere on that same network. Often, the devices can be monitored and sometimes controlled via a Web browser.
For remote DAQ applications within a few
miles, serial data acquisition modules (sometimes referred to as Serial I/O
modules) can be used to perform measurement and control functions.
Instead of interfacing with a personal
computer’s parallel port, serial data acquisition modules use a serial
interface. This interface is usually an RS-232, or RS-485 serial interface.
This interface is used for two-way communications with the module. It is used
to send signals to the module to control it, as well as receiving the data
results from the module.
In other applications, remote DAQ might be
satisfied with a portal computer or laptop PC, bring the data acquisition
system to the source of the measurement. This is also referred to as
field-testing or measurement. In many cases this type of remote data
acquisition can be accomplished using a laptop PC and a USB DAQ device from Measurement Computing Corporation. These powerful data acquisition devices
plug directly into a USB port and provide plug-n-play, 16-Bit data
acquisition capability.
Other remote DAQ applications might require
the use of a modem, cell phone or direct satellite up or down link. These
applications are typically use when the environment is not suitable for local
human interaction. Some applications for this level of remote DAQ usage can be
in automotive testing, automotive racing, geophysical measurements or airborne
situations.
