The invention discloses a distributed test system based on CompactRIO and an optical fiber network. The distributed test system includes a near-end real-time measurement and control device, a field control device and a remote-end real-time monitoring device; the near-end real-time measurement and control device is used for receiving and analyzing the signals from the field control device, completing interaction with a measured object so as to obtain the signals of the measured object, and transmitting the signals to the field control device; the field control device is used for setting the time sequence scheduling signals and information forwarding control signals of the near-end real-time measurement and control device, transmitting the signals to the near-end real-time measurement and control device, and reversely transmitting the received signals of the measured object to the remote-end real-time monitoring device; and the remote-end real-time monitoring device is used for receiving, performing analysis processing and real-time monitoring on the signals of the measured object transmitted by the field control device and completing abnormal information status warning and fatal fault emergency processing. The test system is set in a distributed manner, and therefore, requirements for remote data interpretation can be satisfied. The test system has high universality and high expansibility.
Description
technical field [0001] The invention relates to the technical field of testing. More specifically, it relates to a distributed test system based on CompactRIO and optical fiber network. Background technique [0002] The test system is an inspection tool for the quality of electronic products, and can provide regular maintenance for products to ensure stable and reliable work. However, with the increase in test complexity, the consumption of on-site testers is increasing day by day. In order to get rid of on-site constraints, remote control and Surveillance becomes an urgent need. [0003] The currently widely used test system is mainly composed of a main control computer, a measurement and control combination, and a data processing computer. It does not have the ability to interpret all test signals in real time. Unable to meet the demands of the explosive development of electronic products. Contents of the invention [0004] The purpose of the present invention is to p...
