It is currently highly demanded to achieve a home health examination device for multiple physiological data and remote monitoring. In this paper, we propose a scheme to detect and transmit multiple physiological data, and then display them on smart devices by the Bluetooth. Further, these messages are sent to the web server for remote monitoring based on the Internet. The mobile terminal programs...
In electro-magnetic coupling sensing system, the amplitude of the coupling signal should be obtained by AC signal sampling. We use the direct sampling and the signal processing calculation method to determine the signal amplitude. The coupling sensitivity of electro-magnetic coupling sinusoidal signal is related to the frequency of signal. When the frequency of signal increases, the sampling rate...
With the development of mobile Internet and Smart home technology, remote intelligent meter reading has become a new trend. In this paper, we propose a method for real-time remote gas reading meters based on Wi-Fi wireless network. The system uses MSP430F4152 microcontroller as the core unit with very low power consumption. The gas usage information is collected by a reed sensor, which is computed...
The reinforcement affecting the chloride concentration distributing in concrete is analyzed based numerical simulation method. The results show the reinforcement alters the pathway for chloride transporting and in turn causes the chloride concentration to accumulate faster in the region adjacent to the side of the reinforcement closest to the exposed surface. Ignoring the effect of reinforcement can...
The technical structure of a composite function block with self thermal insulation is introduced. Block — thermal insulation layer-protective layer trinity is achieved through setting tie bars within the block. The block not only collects multiple functions to one body, such as load-carrying/maintenance, thermal insulation, drainage and exhaust, anti-shedding and anti-crack for surface layer etc....
This article uses unascertained mathematics measure model to assess energy-saving conditions of construction management process. The target of this method is minimum energy consumption in the whole system of construction and is to identify factors which may cause energy wasting happen during construction. This method can prevent the occurrence of energy waste. In order to do the quantitative analysis...
