Press the stop acquisition button to stop the acquisition and close the queue. The collected analog signals, digital signals and pulse quantities form different waveform arrays due to different properties. By establishing an index, the system can process different types of signals separately. Signal analysis and processing has powerful data analysis and processing functions. Its signal processing palette has built-in modules for signal time domain analysis, frequency domain analysis, signal generators and filters. The time domain analysis module uses a waveform measuring tool to measure the peak value and the mean square value of the analyzed signal; the frequency domain analysis module uses the amplitude spectrum, the phase spectrum, the autocorrelation function to filter the signal, and the Fourier transform; and on this basis Information fusion technology was introduced to improve the accuracy of the system. By performing time domain, frequency domain and correlation analysis on the collected signals, it is possible to accurately judge whether the hoist system has a hidden trouble. The data storage and query system data storage and query are realized by using the database access tool. The access technology is used to realize the operation of the database through the programming model. The structured query language is used to complete the access to the database, including updating and extracting the database. The data. First, the function creates an object, and the function establishes a connection with the database; then the function creates a data set, and the data in the database can be obtained by using the query command; the running parameters of the hoist system are saved at regular intervals through the function; And send it to the front panel to display it in the table, and you can back up the print.
