According to the actual needs of the modern intelligent building, this paper introduces a intelligent meter reading system based on Nios II, which used the field programmable gate array FPGA EP2C35 and wireless transceiver chip nRF905 and then finished the design of the automatic meter reading system of the building. At the same time, it put forward the hardware structure of the system and software...
This paper presents design principles of a low-power and portable bioelectrical impedance analyzer. Based on the low-power and portable notion, It uses a low-power computer as the core, adopting MSP430F149 chip as the processor and utilizing AD5933 which is launched by Analog Devices and is highly integrated to measure and collect the multi-frequency impedance information. And then these data will...
Anti-flood Spiral pile driving system which consists of spiral pile and spiral pile driver is developed to solve the problems of the traditional woodiness pile driving system in flood preventions. With the gradual application of spiral pile in flood preventions, better spiral pile is needed to design and a more stable driver system is required. In this paper, ANSYS / LS_DYNA is used to build up spiral...
