Simple controller applicable to human-computer interaction of numerical control machine tools

Abstract

The invention discloses a simple controller applicable to human-computer interaction of numerical control machine tools. The simple controller is a technologically improved invention in the field of industrial automation control and can be used in all machine tools adopting the numerical control systems of the DMG. The simple controller is mainly composed of a power supply unit, a communication unit, a control unit, and a display unit. Data interaction with all types of PLC systems is realized through six common I/O ports. A three-line serial data bus is defined, and LCD and LED display control is realized. An extendable RS232 serial bus is designed, which facilitates data storage and debugging. Through high-speed optical coupling isolation, the stability of signal reading is ensured. The problem that a controller is hard to generalize and high in cost, and has a complex communication system is solved effectively. The simple controller has very high use value.

Description

technical field [0001] The invention belongs to the technical improvement invention in the field of industrial automation control, and can be used in all numerical control system machine tools of DMG. Background technique [0002] The working status and information query of traditional CNC machine tools needs to be inquired by a special person in the CNC system, and the human-computer interaction is not intuitive; various bus communications are established between various human-computer interaction controllers and PLCs, such as establishing Profibus bus communications with Siemens PLCs, and Mitsubishi PLC establishes Modbus bus communication, so it is difficult for the controller to be universal. Even if it is universal, there are problems such as high cost and complicated communication system; [0003] Most of the controllers and LCD and LED display units use parallel bus communication, which has problems such as occupying a lot of controller resources, complicated connecti...

[0002] The working status and information query of traditional CNC machine tools needs to be inquired by a special person in the CNC system, and the human-computer interaction is not intuitive; various bus communications are established between various human-computer interaction controllers and PLCs, such as establishing Profibus bus communications with Siemens PLCs, and Mitsubishi PLC establishes Modbus bus communication, so it is difficult for the controller to be universal. Even if it is universal, there are problems such as high cost and complicated communication system;

[0003] Most of the controllers and LCD and LED display units use parallel bus communication, which has the problems of occupying a lot of controller resources, complicated connection, and high failure rate.
