Description

Technical Field

[0001] The utility model relates to the technical field of intelligent buildings, and particularly relates to a handheld terminal for intelligent buildings. Background Art

[0002] An intelligent building refers to the intelligent transformation of a building through technical means such as the Internet of Things, cloud computing, big data, artificial intelligence, etc., to achieve automatic control and information management of various facilities, and improve the safety, comfort, and intelligence level of the building.

[0003] Intelligent building is a marginal and cross-disciplinary subject, involving computer technology, automatic control, communication technology, building technology, etc., and more and more new technologies are applied in intelligent buildings.

[0004] An intelligent building can achieve security management of the building interior through means such as video surveillance, access control systems, and fire protection systems. For example, through face recognition technology, it can achieve identity authentication and recording of people entering and leaving, and through devices such as smoke detectors and temperature sensors, it can monitor the fire risk inside the building in real time, give an alarm in time, and take corresponding measures. An intelligent building can achieve energy management of the building interior through means such as intelligent lighting, air conditioning systems, and elevator systems. For example, through devices such as light sensors and infrared sensors, it can automatically sense and adjust the indoor light and temperature, achieving energy conservation and environmental protection. An intelligent building can achieve operation and maintenance management of the building interior through means such as big data analysis and operation management platforms. For example, by analyzing various data and information inside the building through big data, it can perform predictive maintenance and optimization on facilities, improving the operation efficiency and reliability of facilities.
