A design solution of machine tool control system and its hardware and software design were proposed for the requirement of high precision internal grinding. The ARM microprocessor was used as the system control center and the technical grade touch screen was used as the human machine interface. The feed motion of the X, Z 2-axis servo motor was controlled by the system to complete the grinding path, and the machine tool switching signal was controlled by the Soft PLC Technology. The whole system has the advantage of stable, high performance and user friendly, meeting the requirement of high precision grinding.

A solution is proposed to design and build virtual elevator model by software for the elevator manufacturing industry, which realize the communication between virtual elevator model and TwinCAT soft-PLC. To test the correctness of this approach, the ten layer virtual elevator model is simulated through TwinCAT soft-PLC. And the usability of simulation system and the reasonableness of control programming method are verified. The main characteristic in this new research method is to use virtual controlled object and virtual PLC. It means that all research work can be finished with full virtual system and its research results can be used well in elevator manufacturing industry.

Set Up

A model of wireless network data interchange was built to solve cross-platform exchange data in intelligent robot. In the framework of embedded Soft-PLC - Codesys real-time operating system, we apply Socket network programming technology based on TCP/IP communication protocol to set up a physical channel between VC++ platform and the Codesys platform. It realizes the real-time data exchange between host-computer and slave-computer uploaded embedded operation system of robot. A special multi-threaded processing class was developed to enhance the multi-tasking allocation ability of the system. Exchanged data was packaged and analyzed to ensure the accuracy of transmitted data. The experiment shows built communication system platform is justifiable, and data transmission speed is less than 10ms. It is able to meet the needs of real-time control in intelligent robot.
