Device and method for real-timely monitoring signal conversion of servo motor control system

Abstract

The invention discloses a device and a method for real-timely monitoring the signal conversion of a servo motor control system, wherein an isolating circuit of a high speed photoelectric coupler digitally isolates a clock signal of a single peripheral interface (SPI) bus, a data signal and an SPI selective signal from equipment, a complicated programmable logic device receives the data bits which are isolated by the high speed photoelectric coupler and combines every 16 data bits into a data byte, and the data byte is sent to a data buffer area in a universal serial bus (USB) device controller; a circuit of the USB device controller sends the data in the data buffer area to a computer; and an electrically erasable programmable read-only memory downloads the USB equipment controller code which is stored in the electrically erasable programmable read-only memory into the USB equipment controller. The transmission rate between a digital signal controller and a computer can be obviously improved, the working state of a servo motor is more intuitively reflected, and the real-time monitoring of the servo motor control system is realized.

Description

technical field [0001] The invention relates to a real-time monitoring signal conversion device and method for a servo motor control system. Background technique [0002] When building a servo motor control system or performing on-site debugging of a servo motor control system, engineers and technicians often need to obtain real-time parameters such as the target speed of the motor, feedback speed, speed error, rotor position, instant current of the motor winding, and DC voltage of the inverter. , the real-time requirements of these parameters are usually at the microsecond level. In order to meet the real-time requirements, the digital signal controller needs to use a high-speed bus interface to communicate with the computer. At the same time, in order to facilitate the operator to observe these parameters, it is necessary to use the corresponding application software to read the data on the high-speed bus, and display the real-time values ​​or real-time curves of these pa...
