A new detecting platform has been designed and developed to improve the performance of suspended access platform’s hoists in the paper. The new platform consists of a mechanical and control piece. The core control system is designed based on S7-200PLC and VB6.0; Computer is a superior machine and S7-200PLC is an inferior machine in the system; VB6.0 is used in the superior machine as the development platform. Testing data will be saved into Excel2000 by using VB's OLE automation technology; and in the VB environment, using OPC standard drive will complete real-time data communication between superior and inferior, also complete data processing at the same time. Therefore, Man-machine interface and reliable control system can be built. The inferior computer can achieve running and testing process control of hoists and collect the data of tension, vibration and temperature of hoists. The practical application of the platform shows that the system can well reduce the time costs and improve test results’ inaccurate of existing detection methods. The detection efficiency is improved; the labor intensity of operators and the running costs of produces are reduced, greatly.

DCS is also known as Distributed Control System, which is based on multiple microprocessors, a combination of Computer, Communication, CRT and Control 4C technology. It is a new type of Control System. The design principle of DCS is decentralized control, centralized operation and decentralized management, and autonomy and comprehensive coordination. The characteristics of the DCS are control dispersion, information focus; Modular system; the strong ability of data communication; friendly and rich man-machine interface; high reliability. DCS system now is used in more and more industries, after constant improvement and changes, is also more and more powerful, and becomes the most widely used process control system in electric power, chemical, metallurgical and other industries.

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.

The Spherical Wheeled Robot (Ball-Bot) is a family of robots that can maintain balance standing on a ball and use it as its wheel to move around. In recent years, there have been several successful Ball-Bot designs. We attempt to develop a new spherical wheeled robot product named "Q-Baller" to study its dynamics and control system. The Q-Baller has been designed to ahieve the economic and effective prototyping. A detailed dynamic model of the mechatronic system has been established and analyzed. Control studies have been conducted based on the dynamic models, and new control methods has been proposed to realize continuous gain scheduling. Exclusive simulations have been performed to test the performance of the controllers and reference planning. The Q-Baller hardware has been prototyped and functional. Robotic circuit board, human machine interface and embedded control system have also been developed to make up the full robotic system. The Q-Baller prototype will be tested after the system is fully adjusted, and further researches in control and robotics will be conducted in the future.

In order to meet the high speed, high precision, high reliability of the packaging machine, a novel control system is provided. In the hardware, the main circuits consisted of main processor module, memory module, temperature measurement and control module, input signal detection module, material split packing module, output driver module, human-machine interface module, system monitor module, power module and JTAG debug module, etc. In the software, the multi-tasking operating system μC/OS-Ⅱ and the graphical user interface μC/GUI were successfully transplanted into LPC2478. Then an experimental platform was established. And many control tasks, including automatic measurement, making bags, loading, transferring, pumping vacuum, sealing and data display, were automatically and continuously executed on the platform. Finally the results show: the machine can package 30 packets (5 g per packet) in a minute; the packaging errors ≤ 0.2 g; the packaging qualified rates ≥ 93%. In conclusion, the system performance is good.
