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.

In this paper, an extended-range hybrid solar-cell and battery powered bicycle through a wireless sensor network (WSN) for far-end network monitoring solar energy to charge two lead-acid batteries and the effectiveness analysis is proposed. In order to achieve this goal, the key component of ZigBee used for a far-end wireless network supervisory system is setup. By adding a small-powered solar panel to charge two batteries when idle or low power periods, an extended-range hybrid powered bicycle allows its driving distance to be increased further. The alternative with this solution, though, are weight and cost. Experimental results prove that our prototype, the solar energy powered bicycle, can manage the solar energy for charging two lead-acid batteries pack to extend its range. As a result, the user by the wireless network in parking period knows the data on the amount of immediate solar radiation, the degree of illumination, the ambient temperature, and electrical energy storage capacity information by the internet interface.

In view of the development of wireless sensor system data transmission model in mine mechanical, we construct a ground reflection model of double path combined with the actual background demand based on the analysis of the wireless network routing protocol. Firstly, we put forward the selection strategy on wireless communication transmission power of multiple information sensor nodes. To build a data communication mode, we proposed the selection and evaluation method of network parameters based on graph theory. In consideration of the wireless channel model, combined with the initial random layout problem of network node, we explore whether to be neighbors between any two nodes arranged at random and the constraint relationship of wireless communication distance between nodes. Finally, we make up a dynamic routing selection algorithm with a view to dynamic nodes, and conduct the simulation analysis and experiment design. The research results show that with the increase of the random movement speed about network nodes, the process of depleting the energy of the nodes in the wireless sensor network speeds up, which explain the protocol given in the paper requires more energy to cope with the problem that the network topology changes frequently because of the random motion of nodes in network. The research results provide a reference to the wireless network node research and design in the electromechanical integration design.
