Adjustment System

In order to solve the existing problems of inefficiency, instability, inaccuracy and low degree of automation, the roll position automatic adjustment system is designed for the one-time forming of cold-formed steel unit. The automatic control technology, sensor technology, communication technology and human–machine interface (HMI) configuration technology are applied to this system and the high-performance PLC controller is used as control core. Triple-phase asynchronous motors are controlled by PLC (S7-1500) to drive the gear connected with reducer and coupling so as to drive the rolls connected with the upper and lower horizontal axes to move. The osiswitch is used to calibrate zero position and the closed-loop control system is constructed by analyzing and feedbacking the signal of the sensor. In this way the system can improve the roll position adjustment accuracy. The practical applications show that the whole system is simple, stable and efficient and the maximum detection error of roller displacement is only [Formula: see text]2[Formula: see text]mm. The system can automatically call the corresponding roll position data according to the specification of the steel pipe. The system not only improves the adjustment speed and accuracy, but also avoids the waste of manpower so that the enterprise production efficiency can be greatly improved. Meanwhile, in order to carry out efficient management of the unit, the unit’s health management system was used to analyze and monitor the status of the unit in real-time.

Role Of Information

This chapter deals with the issue of information in systems theory. Systems theory requires the use of undistorted information in approaching both the system, as such, and its components, including the relation established between them. Systems theory places the study of automatically adjusted systems at its very centre. The management of systems must provide those actions of eliminating the negative consequences caused by distorting the information used in the system. The following chapter discusses the theoretical approach of the “system” concept, use of the analysis and synthesis method in systems theory, modelling and simulating the systems, automatic adjustment systems, automatic adjustment system-management system interdependence, systems management, and more. The conclusion emphasizes the role of information in the management of systems and the possible distortions of information that can occur when it is not properly used in the system.

Background: Patient-ventilator asynchrony is common during pressure support ventilation (PSV) because of the constant cycling-off criteria and variation of respiratory system mechanical properties in individual patients. Automatic adjustment of inspiratory triggers and cycling-off criteria based on waveforms might be a useful tool to improve patient-ventilator asynchrony during PSV.Method: Twenty-four patients were enrolled and were ventilated using PSV with different cycling-off criteria of 10% (PS10), 30% (PS30), 50% (PS50), and automatic adjustment PSV (PSAUTO). Patient-ventilator interactions were measured.Results: The total asynchrony index (AI) and NeuroSync index were consistently lower in PSAUTO when compared with PS10, PS30, and PS50, (P < 0.05). The benefit of PSAUTO in reducing the total AI was mainly because of the reduction of the micro-AI but not the macro-AI. PSAUTO significantly improved the relative cycling-off error when compared with prefixed controlled PSV (P < 0.05). PSAUTO significantly reduced the trigger error and inspiratory effort for the trigger when compared with a prefixed trigger. However, total inspiratory effort, breathing patterns, and respiratory drive were not different among modes.Conclusions: When compared with fixed cycling-off criteria, an automatic adjustment system improved patient-ventilator asynchrony without changes in breathing patterns during PSV. The automatic adjustment system could be a useful tool to titrate more personalized mechanical ventilation.

As people’s life quality rise continuously, the fitness industry has developed fast. At present, people mainly focus on the improvement and research of fitness bike’s comfort and security, not on the movement manner. Thus it causes the movement process to be drab and boring, which has negative effect on the exercise. Therefore, Shenzhen Institute of Advanced Technology developed a new kind of multifunctional interactive fitness bike. Its characteristic is that both hands and feet can driver it independently, which can add different movement manners. This paper mainly aims at designing a new kind of resistance automatic adjustment system according to its unique drive mode. This system can make the rider obtain smooth and comfortable feel. At last, through the manufacturing and debugging of the prototype of fitness bike, we know this scheme is feasible.
