A novel automated balancing and correcting machine is proposed and studied. Its structure, composition and control system are introduced. A data acquisition card with USB2.0 interface is used to obtain the real-time unbalanced signal. The rotor unbalance and the mass need to be removed are calculated according to the unbalanced measurement principle. The feed which is needed to complete the correction is deduced by integration method on the basis unbalance measurement and correction principle. The AC servo motors with high precision and fast response are used to drive the rotor to achieve fast and accurate unbalance measurement and correction. A prototype according to the principle is manufactured to test the thinking. Experiments proved that the unbalance reducing rate at one time correction more than 95%. It is necessary to further industrial development.

Time Acquisition

The system is a data acquisition and control system used for multi-channel. It is based on the integration of LabVIEW, PCI data acquisition card and intelligent self-tuning PID. Aiming at the ART’s data acquisition card, the paper introduces on the allocation of LabVIEW and Non-NI data acquisition card. The modular design is adopted to realize real-time acquisition, processing, display, save and error messages for multi-channel signals. Utilizing exported standard signals and real-time signals via data acquisition card, we have controlled furnace temperature by intelligent self-tuning PID and made its range in certain variation change according to standard time temperature curve. And the practical application shows that the system works in the stable condition.

Automatic Scheduling

Positron emission tomography (PET) is one of the commonly used scanning techniques. Medical staff manually calculate the estimated scan time for each PET device. However, the number of PET scanning devices is small, the number of patients is large, and there are many changes including rescanning requirements, which makes it very error-prone, puts pressure on staff, and causes trouble for patients and their families. Although previous studies proposed algorithms for specific inspections, there is currently no research on improving the PET process. This paper proposes a real-time automatic scheduling and control system for PET patients with wearable sensors. The system can automatically schedule, estimate and instantly update the time of various tasks, and automatically allocate beds and announce schedule information in real time. We implemented this system, collected time data of 200 actual patients, and put these data into the implementation program for simulation and comparison. The average time difference between manual and automatic scheduling was 7.32 min, and it could reduce the average examination time of 82% of patients by 6.14 ± 4.61 min. This convinces us the system is correct and can improve time efficiency, while avoiding human error and staff pressure, and avoiding trouble for patients and their families.

Aiming at the management problem of real-time data created while intelligent solar street lamps working, sectional data acquisition and control system based on internet of things is introduced in the paper. Communication protocol with unified form and flexible function is designed in the system, and communication address is composed of sectional address and subsection address. Three-level data structure is built in the polling algorithm to trace real-time state of lamps and to detect malfunction in time, which is suitable for sectional lamps management characteristics. The system reflects necessary statistic data and exception information to remote control centre through GPRS to short interval expend on transmission and procession and save network flow and system energy. The result shows the system brings improved management affection and accords with the idea of energy-saving and environmental protection.
