Currently, the world has a lot of research and practical application of intelligent building systems integrated with intelligent power systems. Because Vietnam is a country with potential for solar energy, the integrator of solar energy is being strongly developed. However, the research result of the optimization of electrical energy used by the intelligent type solar integration is rare. This paper presents the design and structure of the module of intelligent control and monitoring via wireless network integrated with the automatic solar concentration system. The system allows easy connection and operation of all electrical power sources including the dispersal solar power to ensure the efficient and lower power consumption. In addition, the solar cell system is applied the Maximum Power Point Tracking technique (MPPT), which helps to stabilize and improve the power generation efficiency of the PV panels. The test results on the module showed absorption performance of automatic solar-cell flat plate systems is raised by 20-30% and power consumption in small households reduced approximately 30%.

The full use of renewable energy sources such as solar energy to meet the various energy supply needs of buildings is now a research focus and an industry development trend, as energy consumption has been increasing and environmental pollution has become a serious problem. In the high-cold and high-altitude area in western China, due to the abundant solar energy and hydropower resources, the use of electric auxiliary cross-season solar heat storage heating system (CSHSHS) is an effective way to achieve clean heating. In this article, the authors applied a CSHSHS in a typical town in the Sichuan West Plateau and analysed and compared three operation strategies: heating storage priority control mode; electro-thermally assisted priority control mode and hybrid control mode. The results show that the heat storage priority control mode would require a large installed capacity of electrical auxiliary heat. The power consumption of the electro-thermally assisted priority control mode is high. The hybrid control mode can effectively reduce the installed capacity of the electrical auxiliary heat and the power consumption in the heating season. The solar fraction of the hybrid control mode was 38.29%, which has an obvious advantage. The results are of great engineering significance for optimizing the operation strategy of CSHSHS.

With the development of society, the energy as the restriction of human society's development is tension increasingly, solar energy as one kind of green non-pollution energy is developed and used gradually. The combination of solar energy water heating system and buildings become more and more closely, however, the power consumption of the pump as the main energy consumption of a solar energy water heating system, the setting of the pump circulating temperature influent the power consumption of the whole system directly. This paper mainly analyze the content above. In order to give some useful advice on the design and operate of the solar energy water heating system in the future.

Charge Pump Circuit

We propose variable pumping frequency (VPF) scheme which is merged with the previous reconfigurable charge pump (RCP) circuit that can change its architecture according to a given sunlight condition. Here, merging the VPF scheme with the architecture reconfiguration can improve percentage output currents better by 21.4% and 22.4% than RCP circuit with the fixed pumping frequencies of 7 MHz and 15 MHz, respectively. Comparing the VPF scheme with real maximum power points (MPP), the VPF can deliver 91.9% of the maximum amount of output current to the load on average. In terms of the power and area overheads, the VPF scheme proposed in this paper consumes the power by 0.4% of the total power consumption and occupies the layout area by 1.61% of the total layout area.

One of the best ways to monitor the health of the heart is to regularly record its electrical activity by using an electrocardiogram (ECG). Abnormal ECG signals may indicate conditions such as heart attack, arrhythmia, or heart defects. There are many ECG devices available which can detect and amplify this differential biological signal from the heart, allowing a lot of information to be collected quickly. The ECG is often small and easy to use, but its power is supplied from regular batteries, which need to be replaced after a certain period of use. This causes discomfort for elderly users. To overcome this limitation, in this paper, we aim to develop a solar-powered, portable Bluetooth device for ECG measurements. The device can be interfaced with smartphones or other wireless devices via Bluetooth by a distance up to 100 m. The ECG device was designed to use solar energy, which is also the main power source. Following the solar energy harvesting circuit is a solar panel with an output voltage of 2.4 V and a power out of 0.25 W. We optimized the design to have a very low power consumption and in sleep mode the current consumption is only around 40 µA. The device was designed with 24-bit resolution and a sampling frequency of up to 2133 Hz, which can allow high accuracy ECG measurements. The device is not only used for heart rate monitoring, but it can also assist doctors in analyzing ECG signals with a high accuracy via embedded operating software.

El siglo XX ha traído un desarrollo sin precedentes en la historia de la humanidad con avances impresionantes en todas las disciplinas de la ciencia y de la técnica. Sin embargo dichos avances no han sido algo gratuito, sino que han tenido un precio que no sería descabellado considerar que, bajo determinados prismas, ha sido excesivo. Durante los últimos 100 años, la población humana en la Tierra se ha multiplicado por un factor de 4 (pasando de 1.600 millones de personas en 1.900 a los más de 6.000 millones de la actualidad). Sin embargo el consumo de agua se ha multiplicado por 9 en el mismo periodo y el consumo de energía por 16, y ello con una degradación asociada del medio ambiente y los recursos naturales, en general, muy significativa. Palabras clave.-Energía solar, Desalación solar. ABSTRACTThe XX century has brought an unprecedented development in the history of humanity with impressive advances in all disciplines of science and technology. But these progresses have not been something free, but have had a price that would not be unreasonable to consider that, under certain prisms, has been excessive. During the past 100 years, the human population on earth has increased by a factor of 4 (from 1600 million in 1900 to over 6,000 million today). However water consumption has increased by 9 in the same period and power consumption by 16, and therefore associated with a degradation of the environment and natural resources in general, very significant. Keywords.- Solar energy, Desalination solar.
