With the growth of the population in the world, energy problem has become a major topic in the world. Energy conservation has become an important part of China's national development strategy. The use of microwave heating instead of traditional heating can greatly improve the utilization rate of energy, and then achieve the goal of energy conservation and emissions reduction. However, due to the uneven...
Ultrasonic thermometry is a kind of emerging acoustic pyrometry technology, and it can break through the limitation of various electromagnetic environment, where the traditional temperature measurement methods have failed to operate satisfactorily. The temperature on the current path can be retrieved by the speed of the ultrasonic wave. When the measurement path is fixed, the key issue of ultrasonic...
To solve the impact of high concentrations and the two-value problem caused by catalytic combustion gas sensor detecting high concentrations of methane, The paper has analyzed the theories and studied the measurement methods of catalysis combustion gas sensor in thermal conductivity and catalytic combustion mode, proposed the research method of methane measuring technique with full range by catalytic...
An intelligent system for monitoring and controlling of the grain condition is designed. The system is based on embedded ARM9 core processor, using SCM for the lower machine control unit. The grain environment Information such as temperature, humidity, and CO2 concentration is collected and stored by Multi-sensor. Then the data is processed via multi-regional information fusion. The levels of the...
Due to massive date to be monitored for Metro shield machine, in order to solve the problems of knowledge acquisition bottlenecks and complexity structure of network structure and long traing time which based on expert system and neural network fault diagnosis methods. This article will introduces rough set theory to the subway shield machine fault diagnosis, Propose a method which based on rough...
In view of the variety of the changes of burning flame in large-scale boiler, in order to master the status of the furnace flame in real time. In this paper, it introduces the BP neural network absorb the basic method of flame-picture's temperature, to study thoroughly discussed about the BP neural network model, and puts forward an improved BP neural network method, as for the method to calculate...
Integration of sensors, embedded operating systems, wireless networking technology, wireless sensor networks, is a new information gathering and processing technologies, in environmental monitoring has a very good application and advantages. This paper introduced a method model based on ZigBee-technology. Depending on specific situation in environment, LEACH communication protocol was chosen. The...
In order to ensure that the food grain storage security, while the smallest energy consumption of monitoring system, designed to application in grain depot monitoring system by clustering technology of wireless sensor networks (WSN). Designed to MSP430 MCU and CC1100 RF chip modules at the core ultra-low power node, the use of hierarchical structure of the networks is divided into a number of clusters...
