In recent years, with the rapid development of computer technology, computer control system has received extensive attention and application. It can not only improve the status quo of traditional work, but also improve the effect of various control work by means of computer control system. However, if the computer control system lacks of reliability, the application of the system will be adversely affected and even economic losses will occur. Based on this, this paper studies the reliability of the computer control system and puts forward some technical suggestions on the reliability of the computer control system in order to provide help for the good operation of the computer control system.

With the improvement of the overall development level of the society, it is difficult for the traditional education mode to meet the needs of talent training. It is necessary to emphasize the reform and innovation of curriculum teaching. Therefore, the country and society have constantly enhanced the emphasis on education mode and education reform and innovation, requiring educators at all levels to start from their own point of view to implement the teaching reform in place. Based on this, the computer control system of the teaching reform work is analyzed, simply expounds the problems existing in the teaching reform of computer control system, then respectively from education model changes, teachers' construction and discipline construction optimization and so on three aspects, put forward the countermeasures of computer control system of the teaching reform work.

Unmanned autonomous transport vessels (MASS) are the future of maritime transport. The most important task in the design and construction of unmanned ships is to develop algorithms and a computer program for autonomous control. In order for such a computer program to properly control the ship (realizing various functions), the ship must be equipped with a computer system as well as measurement sensors and navigation devices, from which the recorded parameters are processed and used for autonomous control of the ship. Within the framework of conducted research on autonomous ships, an experimental model of an unmanned ship was built. This model was equipped with a propulsion system not commonly used on transport vessels (two azimuth stern thrusters and two bow tunnel thrusters), but providing excellent propulsion and steering characteristics. A complete computer system with the necessary measuring sensors and navigation devices has also been installed in the model of the ship, which enables it to perform all functions during autonomous control. The objective of the current research was to design and build a prototype computer system with the necessary measurement sensors and navigation devices with which to autonomously control the unmanned ship model. The designed computer system is expected to be optimal for planned tasks during control software tests. Tests carried out on open waters confirmed the correctness of the operation of the computer system and the entire measurement and navigation equipment of the built model of the unmanned transport vessel.

The experimental set-up working on the zero-degree beam-line of the 9MV Tandem Accelerator at IFIN-HH now offers a high accuracy and repeatability of the heavy ions nuclear physics experiments. This is achieved by an automated moving system, placed inside a circular reaction chamber, consisting of four moving arms covering a complete 360 degrees. Each arm can hold one detector and is powered by a stepper motor having the possibility of micro-stepping up to 1/256 if the application requires, with a reduction gear box of 60:1 and a resolver acting as a witness for eventual position corrections. Moreover, the target support, positioned in the center of the chamber, is also assisted by a stepper motor and can rotate over 360 degrees clockwise or counterclockwise. Two identical Delta E - E telescopes have received an upgrade in both the gas automated pressure and constant flow regulation by using a software implemented PID (Proportional-Integral-Derivative) controller.

Cold wire feeding plus MIG-based shaped metal deposition process has been proved to be a promising technology capable of using materials and energies reasonably to manufacture complex large-scale metal components. The shaped metal deposition with cold wire feeding process is suitable as an alternative technique for traditional manufacturing methods, especially for complex and large-scale solid parts and it is especially used for structural components in aerospace and the manufacture and repair of dying/molds. In this paper, a new experimental setup was developed, which consists of a MIG welding source, an external cold wire feed unit and a 3-axis machine. The paper explains the design, implementation, and stages of control programing (CAD-CAM) of the developed system. Furthermore, the paper presents the important design steps from the design database using CAD to the final shape of the part to be configured. The proposed system is capable of producing parts of different shapes in sizes of more than 450 mm directly from the computer-aided design. Several components are fabricated with SS309L components to achieve the capability of the advanced proposed system. The results showed that the integrated system and the program are feasible and flexible and hence can be used to manufacture variously shaped parts.
