A data analysis system is provided in the invention. The data analysis system includes a storage device, a field-data-description-file generating module, and a general data readiness analysis module. The storage device stores a plurality of raw data. The field-data-description-file generating module generates the field-data-description files corresponding to the raw data. The general data readiness analysis module obtains a score of the consistency indicator of the raw data according to the field-data-description files. The general data readiness analysis module obtains the data of the category which needs to be analyzed from the raw data according to the category of each field-data-description file. The general data analysis module obtains the score of the completeness indicator, the score of the accuracy indicator, the score of the validity indicator, and the score of the compaction indicator which all correspond to the data of the category which needs to be analyzed.

Data readiness analysis system and data readiness analysis method

The present disclosure provides an ultrasonic drive and driving method configured for driving an ultrasonic tool. The ultrasonic drive includes a switch module, a sensing element and a control element. The sensing element senses the voltage and current of the ultrasonic tool and generates a sensing signal accordingly. The control element receives the sensing signal and outputs a control signal. The switch module outputs an ultrasonic signal according to the control signal for controlling the vibration of the ultrasonic tool. When the ultrasonic drive operates a frequency sweep function, the control element determines an operating interval and an operating frequency of the ultrasonic signal. When the ultrasonic drive operates a frequency following function, the control element adjusts the operating frequency according to the sensing signal for keeping the impedance of the ultrasonic tool consistent.
