The basic composition of the general computer measurement system includes what the main links

The basic components of a general computer measurement system include sensors, signal conditioners, computers and application software.

Because the computer can only handle digital signals, so the A/D converter becomes an indispensable part of the computer test system. Its main function is to convert analog signals into digital signals, and the conversion results through the communication port into the computer memory. According to the actual need, the computer processing results can be output digitally, or through the D / A conversion to analog output.

Signal conditioning circuit (conversion, amplification, filtering, modulation, etc.) is not only the traditional test system after the sensor is an important part of the computer test system. In order to adapt to the needs of different parameters of the test, often a variety of conditioning circuits for modular design, and with the A/D or D / A converter is placed in a box, called the signal conditioner.

Expanded Information:

Because of the computer signal acquisition and processing has a fast speed, large amount of information, convenient storage and other traditional test methods incomparable advantages, computer test systems have been rapidly developed and applied.

In the production process, the application of this system can be on the production site of the process parameters for the collection, monitoring and recording, but also to improve product quality, reduce costs to provide information and means. In scientific research, the application of computerized testing systems can obtain a large amount of dynamic information, is a useful tool for studying the instant physical process, but also to obtain the mysteries of science is one of the important means.
