This paper designs a intelligence wireless security alarm system based on MSP430 micro controller and nRF905 wireless transceiver module. First, it designs a wireless alarm terminal and formats a distributed wireless network based on TDMA. Alarm terminal adopts ultra low power MSP430F149 as MCU, and nRF905 as wireless chips. It designs the human body detector based on BISS0001, smoke sensor module...
Hypoid mirror can get panoramic images around 360°. Because of this, it can be applied to plant roots morphology monitoring and analysis system. It avoids the complex mechanical design using micro root window method to collect image, which needs to use objective and CCD camera along the tube wall of micro pipe to rotate 360°. It also improves efficiency of root image collection. After collecting image,...
This article discusses the development and implementation of megawatt-class wind turbine fault monitoring system. This system merges the GSM communication technology, DSP control technology, computer networking technology, integrated display technology and information management technology into one organic, and has carried on a comprehensive wireless remote monitoring and control to the wind turbine...
ZigBee wireless sensor network usually works in a complex environment, and the energy of sensor node is very limited, so energy consumption is a big problem in ZigBee wireless sensor network,especially in the multi-sensor system. Plant eco-physiological monitoring system is a typical multi-sensor system. There are many kinds of sensors in this system. These sensors, as well as ZigBee module and some...
A DSP is adopted to construct a fuzzy controlled lithium-ion battery charging system. By using this intelligent charging system, the data collection, calculation and peripheral circuit control are performed for the battery charging status. According to the lithium-ion battery charging specifications, two hours are required for battery charging. A fuzzy logic controller (FLC) is constructed by using...
To understand the spatial interpolation optimization laws of groundwater depth, two different methods of spatial interpolation are compared: (1) inverse distance weighting (IDW), (2) Ordinary Kriging (OK), using the recorded data of groundwater depth in the Shule River basin, China, in March from 2001 to 2006. The result indicates that the accuracy of the OK is the highest. After exploratory spatial...
The information transmission is transparent for the user in the ZigBee wireless sensors network, which are lack of interactivity and self-constrain. The information in the ZigBee wireless sensors network can not be viewed in a real time by a friendly interface. Modbus protocol is embedded into ZigBee stack, in this way, we can implement interaction well and the information can be viewed in a friendly...
