Intelligent control device and method based on embedded system

Abstract

The invention discloses an intelligent control device based on an embedded system, which comprises a shell (6), a built-in or external power supply, an MCU micro-control unit, an I / O module (2), a motor driving module and a communication network card (4), and is characterized in that the MCU micro-control unit is connected to the I / O module (2), the motor driving module and the communication network card (4) through an I2C, SPI or UART system bus and are integrally mounted on a mounting plate (8), the motor driving module is connected to a motor needing to be controlled through a wire and cancontrol the three-phase asynchronous motor to slowly start and stop when the three-phase asynchronous motor is started and stopped. The device serves as an industrial basic device for intelligent manufacturing, equipment can be intelligentized, and the complexity of a control system can be reduced. When the device is widely applied to the system, the use of cables, bridges, control boxes and the like can be greatly reduced, so that the device cost is reduced in the links of design, installation, debugging, maintenance and the like, the manual design cost is reduced, and the technical thresholdof related personnel can also be reduced.

Description

technical field [0001] The invention belongs to the technical fields of transportation, automation control, electrical control, equipment drive, etc., and specifically relates to an embedded system-based intelligent control device and method. Background technique [0002] The current automation equipment control system generally uses PLC (programmable logic controller) to collect the detection switch status information on the equipment, analyze and calculate the control instructions through the prepared program, and send them to the motor driver (motor starter, frequency converter, etc.) to make the motor Operation, so as to achieve the purpose of automatic control equipment operation. As shown in the figure, the current technology has the following deficiencies: [0003] 1) Due to the high degree of discreteness between devices, the design complexity of the entire control system is high, installation and debugging are inconvenient, and the reusability of design results is ...

AI Technical Summary

Problems solved by technology

[0003] 1) Due to the high degree of discreteness between devices, the design complexity of the entire control system is high and installation and debugging are inconvenient, and the reusability of design results is low

[0004] 2) The cost of PLC control is high, the control program is too concentrated, and the computing power is insufficient to run more complex algorithms

[0005] 3) The degree of intelligence of the motor driver is insufficient and does not meet the current system requirements of intelligent manufacturing

For example, the starter only has the basic functions of starting, stopping, forward rotation and reverse rotation of the motor; the frequency converter can realize the slow start and slow stop of the motor, and some high-end frequency conversion can also collect some detection through the extended I / O (input / output) template Switching signals, setting simple logic instructions, but it cannot meet the needs of intelligent systems in terms of data acquisition and analysis such as temperature, current, and life
