Multi-way waveform acquiring and displaying and data analyzing and processing system based on universal serial

Abstract

The invention relates to the field of testing technology of upper computers, and in particular relates to a multi-way waveform acquiring and displaying and data analyzing and processing system based on a universal serial. The system comprises a waveform acquiring and displaying part and a data analyzing and processing part; the system has a multi-threading framework; the waveform acquiring and displaying part is used for obtaining and processing multi-path waveform data uploaded by a lower computer from an RS232 universal serial interface of a PC (Personal Computer), and then displaying the multi-path waveform data in forms of text and oscillogram; and meanwhile, the data analyzing and processing part is used for acquiring, processing and displaying the waveform data, as well as displaying the continuous real-time variation of the waveform. The multi-way waveform acquiring and displaying and data analyzing and processing system has the advantages that a multi-way (4 ways at the maximum) waveform data real-time transmission and shunting displaying system based on the RS232 serial interface is achieved by using a simple and novel method on the PC in which a windows operating system runs; and moreover, the system also merges a data analyzing function, and therefore the system can be used for processing the waveform in each way through the spectrum analysis and a plurality of filtering algorithm methods.

Description

Technical field [0001] The invention relates to the technical field of upper computer testing, in particular to a waveform acquisition display and data analysis processing system based on a universal serial port. Background technique [0002] All aspects of industrial automation are inseparable from actuators. In addition to hydraulic and pneumatic devices, the most widely used equipment is electric motors. There are many types of motors, including stepper motors, DC brushed motors, and three-phase AC motors. Among them, the structure of stepper motor and brushed motor is not complicated, and the control algorithm is relatively simple. Since three-phase AC motors cannot physically commutate, they must be commutation voltage and current through software, so the control algorithm is relatively more complicated. Especially for the servo motors applied to the manipulators of industrial robots, in order to obtain the best working status and efficiency, in addition to adding precisio...
