System and method for reading load spectrum actual measuring experimental data

Abstract

The invention discloses system and method for reading load spectrum actual measuring experimental data. The system comprises a data acquisition device and a computer, wherein the data acquisition device is used for acquiring load spectrum actual measuring data and storing the load spectrum actual measuring data in a data storage card; and the computer is connected with the data acquisition device and is used for reading the data from the data storage card according to the storage strategy and storing the read data into a data file with the designated format to be used by the load spectrum actual measuring experimental data processing system. The invention has high actual value for reading the load spectrum actual measuring data in the actual engineering test and achieves the aim and the requirement of improving the data storage efficiency and flexibly reading.

Description

technical field [0001] The invention relates to the field of basic research on data access technology, in particular to a reading system and method for load spectrum actual measurement test data used in agricultural equipment reliability research. Background technique [0002] In the reliability research of agricultural equipment, the measured data of load spectrum is the basic object of reliability research. In the data collection of agricultural equipment load spectrum experiment, KAM-500 data acquisition system is used. This system can be used for data collection in the process of agricultural equipment reliability test. It adopts full digital base plate design, full system synchronous sampling, digital filtering, hardware and software Advanced design technology, with excellent system expansion capabilities. The KAM-500 data acquisition system uses a CF (Compact Flash) card for data storage. In order to store the collected data efficiently, it uses a unique storage metho...

AI Technical Summary

Problems solved by technology

[0003] First of all, the function is relatively simple, it can only support the overall reading of the entire CF card, and cannot realize the flexible reading of the required recording events or data blocks, resulting in a large amount of additional data when reading data, and poor flexibility;

[0004] Secondly, the saved data formats are limited, mostly in text format. These formats have low storage efficiency and are not suitable for large-capacity and high-speed measured performance requirements.
