Embodiment Construction

[0036] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0037] At present, with the rapid development of social science and technology, vibration sensors and vibration measuring instruments have been widely used in many fields. In order to ensure the reliability of the value of vibration sensors and vibration measuring instruments, it is necessary to perform vibration measurement calibration on them. In this case, the measurement and calibration department The workload of the verification personnel has gradually become heavier, and the error rate has gradually increased. Using this system can directly realize automatic vibration measurement calibration. On the premise of ensuring the high precision of measurement calibration, the workload of the tester is greatly reduced and the labor efficiency is improved. Moreover, the calibration of this system is rich in content, powerful in function, and easy to operate, covering acce...

Abstract

The invention provides an automatic vibration calibration system and a calibration method and belongs to the field of vibration metering and calibrating. The automatic vibration calibration system comprises a control part and a measuring part. The control part is used for controlling frequency and amplitude of a vibration table. The measuring part is used for measuring the amplitude and the phase of the vibration table and measuring signals output by a vibration measuring element. The control part comprises a function generator, an amplitude controller, a power amplifier, a self-adaptive control algorithm module and a fuzzy control algorithm module. The function generator outputs a sinusoidal signal of the assigned frequency F and an assigned voltage amplitude value Uci according to a computer instruction, the sinusoidal signal is output to the power amplifier after passing through the amplitude controller to drive the vibration table to start vibration, and the self-adaptive control algorithm module calculates a corresponding output signal according to the input signal.

Description

technical field [0001] The invention belongs to the field of vibration measurement calibration, and in particular relates to a vibration automatic calibration system and a calibration method. Background technique [0002] Most of the traditional measurement and calibration equipment are manually operated, or use foreign calibration systems. Manual measurement and calibration is time-consuming and labor-intensive, and it is also prone to errors when the workload is large. Foreign automatic calibration systems are expensive, and the low-frequency control system is slow. After comparison, the control system of Spektra Company needs 50 cycles at 0.4Hz, and the control system is slow to adjust, and it is easy to produce a dead zone in the vibration level control, which cannot be performed. Precise vibration level control. Contents of the invention [0003] The purpose of the present invention is to solve the problems existing in the above-mentioned prior art, and to provide a...
