Traditional yeast fermentation process is becoming a big bottleneck recently in Chinese liquor industry, because of the low efficiency and high cost of human labor with little automation. An intelligent automatic yeast fermentation system based on novel designed structure, specialized robot system and wireless multi-sensor data acquisition system, has been introduced in this paper. Standardized parts...
This paper studies the problems for the stability analysis and controller design of wireless sensor networks (WSNs) measurement and control systems. In order to ensure the stability of the systems, we construct proper Lyapunov-Krasovskii functional and employ integral inequalities to analyze the WSNs measurement and control systems based on Lyapunov theorem. At the same time, in combination with the...
By using DS18B20 as temperature sensor, MOC3041 and BTA16 as executive elements, the system can control the power of electric stove to regulate water temperature through the PID algorithm. Then the temperature information of the points is transformed to the host computer system by wireless communication module. The host computer system is used to monitor and adjust the temperature and the liquid level...

This design takes the 16-bit ultra-low power MSP430F149 micro controller produced by TI Company as the control core. Using a high-precision single-bus device DS18B20 as the temperature sensor, the keyboard as the temperature input setting, and the temperature value displayed by the 1602 LCD, temperature measurement and controlling are realized within the closed environment. And the nRF401 wireless...
A protective thermo-physiological clothing was developed, which provides intelligent thermal control function for a wearer by means of integration of smart materials, functional fabric, transducers, microelectronics, Artificial Intelligence (AI) control and wireless data acquisition. The clothing has a thermal control system, a wireless measurement system, a plurality of conductive fabrics, a semiconductor...
Wireless sensor networks are expected fine monitoring in all kinds of environments, but many of these environments, especially the forest, send our wireless sensors transmitting into bad conditions. Reflections and scattering from foliages, collision of simultaneous transmissions, attenuation of the signal, and many other factors make transmission worse and worse. And conditions become extremely awful...
Along with the infiltration of wireless sensor network in every field of our life, sharing sensor network resources in Internet environment is one of key problems which must be solved by wireless sensor network application. This paper expounds Web Service technology and uses Web Service technical framework for reference to design a new kind of service-oriented sensor network structure. And finally,...
As people's living standards gradually improving, monitoring and ensuring the well being of citizen becomes an important part of our social care network. Due to the limitation of the quantity of family physicians and the level of telemedicine techniques, the ideal goal of the family medicine with respect to overall promotion of health care is still far to reach. This paper presents a novel framework...
