Abstract-In order to develop an advanced intelligent building control system, the new system based on mobile wireless Internet of things is designed. By analyzing the new technology, it is proved that the application and development of the Internet of things technology provides a new method for the effective control of intelligent buildings. In addition, a series of researches are carried out on the core technology of the construction equipment networking system. The hardware, software and wireless self-organization networks of the intelligent terminal are designed and implemented, and the key indexes of the intelligent terminal are tested. The fixed transmit power test results show that when the fixed emission frequency is 10 dB, the communication distance is inversely proportional to the communication rate, which means that the smart terminal wireless network has strong ability to pass through obstacles. Based on the above finding, it is concluded that the stability of the mobile internet wireless network intelligent terminal can fully meet the performance requirements of intelligent building control, which lay is a good basis for its flexible use of the future. Keywords-Intelligent building; Internet of things; wireless network; intelligent terminal IntroductionWith the increasing degree of economic and social informatization, the Internet of things and electronic information technology are gradually applied to the field of architecture. Therefore, it has become the focus of attention and discussion all over the world, which gave birth to the intelligent control system of intelligent building. According to relevant data, the energy consumption of construction electricity equipment can account for 80% of the total energy consumption of buildings, which has become the key point of restricting the sustainable development of the construction field [1]. As the number and types of electrical equipment in buildings are increasing, the traditional intelligent building control system cannot meet the needs of people's intelligent, diversified and convenient management and control. Therefore, an integrated control and management system for building electric equipment is urgently needed.
