Embodiment Construction

[0081] In order to make the hardware work, the application program is written in C language, the general program block diagram is shown in image 3 ;

[0082] 1) After starting up, the program draws the main measurement interface according to the predetermined plan, see Figure 4 ;The main interface is divided into 16 areas, and the functions of each area are as follows:

[0083] 1. Other measurement parameter area: respectively display the crest factor and kurtosis value measured at the front and rear (I, II) stations

[0084] 2. Quality statistics area: display the total number of measurements, the total pass rate and the pass rate of groups A1, A2, A3H and A4 respectively.

[0085] 3. Threshold area: display low, medium and high frequency threshold values.

[0086] 4. Judgment area of ​​the quality level of the front (I) station: according to the measurement results of the front station, the achieved quality level is displayed.

[0087] 5. Rear (II) station quality level...

Abstract

A full-automatic railway lorry journal-box bearing dynamic quality testing system is provided, which belongs to the filed of bearing vibration testing and quality controlling. The preposing enlarger is arranged in the sensor; a low, medium and high frequency 8-shift cell-type enlarger and a low, medium and high frequency high pass filter are made on a circuit board A; a low, medium and high frequency low pass filter and a I / O controller and a multi-line A / D converter are made on a circuit B; three-line signal generator are made on a circuit board C; an I / O interface is made on a circuit board D; a power source and a sound volume enlarger are made on a E board. The system is composed of two A boards, two B boards, two E boards, one C board, one D board, two E board total ten separated circuit boards and an IPC. The ten circuit boards are arranged in the main machine case of the IPC. The beneficial effects of the invention are that: the invention can test currently and conduct quality analyzing currently, which is mainly used in the fileds of bearing vibration testing and quality controlling.

Description

technical field [0001] The invention belongs to the technical field of bearing vibration detection and quality control. Background technique [0002] As the speed of railway transportation increases again and again, the dynamic quality of railway bearings becomes more and more important. However, there is no way to detect the dynamic quality of railway freight car bearings in my country. [0003] The dual-channel fully automatic bearing dynamic tester with SPC function can not only detect the dynamic quality of each set of bearings in real time, diagnose and eliminate bearings with defects on the working surface of the bearing, but also has the function of real-time quality analysis. This content fills the blank of domestic bearing dynamic quality inspection. Contents of the invention [0004] The purpose of the present invention is to provide a real-time detection and real-time quality analysis full-automatic railway wagon bearing dynamic quality detection system.
