Problems solved by technology

[0003] Over the years, many countries have made unremitting efforts to realize the dynamic detection of wheel flat scars, and put forward various schemes, but the methods commonly used by the monitoring platform are mainly completed by industrial computers or PCs, and the front end mainly uses The A / D conversion circuit collects data, and then the main algorithm and judgment work are left to the industrial computer to complete. In a sense, this approach does not have a separate overall system control process, and the collected data is completely handed over to the industrial computer. Although it has comprehensive functions, it has many unfavorable factors, such as large size, difficult expansion, high construction cost, maintenance cost and expansion cost, and it is not conducive to on-site observation

[0004] At present, some foreign technical methods have begun to move part of the work of the industrial computer to the front-end DSP data acquisition board to perform most of the algorithm processing. However, due to the complexity of the algorithm and a large number of controls, the efficiency and real-time performance are limited. It is reduced, and this requires the use of high-performance DSP chips, which require high configuration conditions, which increases the cost and makes the design more difficult. Therefore, a reasonable configuration structure and some new design methods are adopted. For the flat wheel The design and application of the detection platform is of great significance
