Abstract
The invention comprises: a 500ksps and 16 bits AD sampler; a high speed data collecting and communicating board; and a PC. Said 500ksps and 16 bits AD sampler is connected to the high speed data collecting and communicating board; the high speed data collecting and communicating board is connected to the PC.
Description
Technical field
The present invention relates to a kind of speed/acceleration vibration system checking instrument.
Background technology
Up to now, in large rotating machinery equipment industries such as electric power (fire/hydroelectric power plant), petrochemical industry, metallurgy, abroad/domestic manufacturer study/producing dissimilar calibration equipments aspect verification speed, the acceleration vibration system, but these equipment are not all also realized the amplitude versus frequency characte and the linear characteristic of verification speed, acceleration transducer all the time, and the linear system sum of errors average sensitivity error of vibrational system (sensor+vibration monitoring instrument etc.).The standard of this kind equipment itself is poor, and thrust is little, and the vibration frequency setting range is little, intelligent data analysis/processing, communication function lack, checking procedure is loaded down with trivial details, and checking data personal error factor is big, even qualified speed, acceleration vibration system verification can be become defective system.
How to solve above-mentioned technical matters and be pendulum and in face of the science and technology personnel, need the problem that solves.
Summary of the invention
The technical issues that need to address of the present invention have provided a kind of speed/acceleration vibration system checking instrument, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
The present invention includes: 500ksps, 16 bit AD sample modules, high-speed data acquisition, communication board, PC; Described 500ksps, 16 bit AD sample modules are connected with high-speed data acquisition, communication board, and high-speed data acquisition, communication board are connected with PC.
Compared with prior art, the invention has the beneficial effects as follows: can carry out high speed, sampling with high precision, adopt DSP to carry out moving in real time/static data processing.
Description of drawings
Fig. 1 is a module map of the present invention;
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
As seen from Figure 1: the present invention includes: 500ksps, 16 bit AD sample modules, high-speed data acquisition, communication board, PC; Described 500ksps, 16 bit AD sample modules are connected with high-speed data acquisition, communication board, and high-speed data acquisition, communication board are connected with PC.
The present invention can carry out linear sensor characteristic and amplitude versus frequency characte verification to the absolute vibration sensor.
The vibrator maximum thrust 150N frequency response 5-2kHz peak acceleration 15g that the present invention adopts, load-bearing capacity 1kg
Be furnished with 5.7inch indigo plant film LCDs on the panel of the present invention, resolution 320 * 240, built-in high-speed data acquisition, communication board adopt 500ksps, 16 AD to carry out high speed, sampling with high precision, adopt DSP to carry out moving in real time/static data processing.
The data that the examining report of providing according to metrology and measurement center Shanghai Institute of Measurement and Testing Technology of East China country provides, the present invention and similar products at home and abroad compare, and specifically are compared as follows:
