Data storage device and data storage method

Abstract

The invention provides a data storage device, comprising an upper computer, a data storage module, a robot controller, a sampling module, a data processing module and a drive module, wherein the upper computer is used as a carrier for debugging software and is used for carrying out online modification of parameters; the data storage module is used for storing the modified parameters by virtue of the data processing module; the robot controller is used for transmitting an operating instruction to the data processing module; the sampling module is used for feeding current, speed and position, which are output by a motor, to the data processing module; the data processing module is used for reading the parameters which are stored by the data storage module, the position instruction which is transmitted by the robot controller and a current value which is fed back by the sampling module in real time, and achieving three-ring calculation of a current ring, a speed ring and a position ring; the drive module is used for receiving the three-ring calculation result, and converting the result into a sine wave to drive the motor to move. The device is capable of reducing data storage errors caused by external disturbance, thus the use precision of a nonvolatile memory is greatly improved.

Description

technical field [0001] The invention relates to the field of robot control, in particular to a data storage device and a storage method. Background technique [0002] EEPROM (Electrically Erasable Programmable Read—Only Memory) has the characteristics of saving data when power off, simple and convenient operation, low price, and long service life. It is widely used in the field of microcomputers and embedded micro-controls. . Usually, the initial parameters of the micro-control system, the initial coordinate position of the robot system, PID parameters, limit value protection parameters, communication parameters, etc. are stored in EEPROM. When the system is powered on, the initial parameters are read from EEPROM. The parameters stored in the EEPROM are very important for the safety, reliability, stability, accuracy, and correctness of the program control process of the system. In an environment with less interference, EEPROM data storage generally does not cause problems...
