Centrifuge data acquisition system

Abstract

The invention relates to a centrifuge data acquisition system. Collected data is from sensors. Types and a quantity of the sensors are determined according to a specific test condition. The centrifugedata acquisition system comprises a conditioning chassis, an acquisition chassis, an instrument cabin uninterrupted power supply, an electric power slip ring, a wireless router, a machine room uppercomputer and a machine room uninterrupted power supply, wherein the conditioning chassis, the acquisition chassis and the instrument cabin uninterrupted power supply are arranged in a centrifuge rotation center instrument cabin; the electric power slip ring is arranged on a centrifuge main shaft; the wireless router is arranged in a centrifuge workshop; and the machine room upper computer and themachine room uninterrupted power supply are arranged in a machine room. Original simulation signal data of the sensors enters into the conditioning chassis, after being conditioned, the data enters into the acquisition chassis, and then the data is digitized and is transmitted to the machine room upper computer through the wireless router so as to realize data acquisition. By using the centrifugedata acquisition system, a restriction of a signal slip ring quantity to an acquisition channel quantity is broken through and an anti-interference capability of the data acquisition system is increased.

Description

technical field [0001] The invention relates to a centrifuge data acquisition system, which belongs to the field of test equipment measurement and control system configuration. Background technique [0002] At present, domestic and foreign test centrifuges generally connect the signal lines of all sensors directly to the signal slip ring of the centrifuge, and directly upload the analog signal to the conditioning and acquisition equipment in the machine room. The number of signal slip rings is large, and the number of acquisition channels is limited. In addition, due to long-distance transmission, the original analog signal of the sensor is usually easily disturbed, and its collection effect is mediocre. Contents of the invention [0003] (1) Technical problems to be solved [0004] Aiming at the above-mentioned deficiencies in the prior art, the present invention proposes a centrifuge data acquisition system, which converts the original analog signal of the sensor into ...
