Indoor multimedia system based on BIM technology

Abstract

The invention relates to an indoor multimedia system based on BIM technology, which includes a BIM operation and maintenance controller and a multimedia mechanism. The multimedia mechanism includes lighting, smart TV, audio and power amplifier. Input circuit, in the indoor multimedia system based on BIM technology, the BIM operation and maintenance controller is used to simulate the indoor multimedia system, so as to improve the construction period and practicability of the system; in the working power circuit, through the fourth terminal of the integrated circuit Output, to control the conduction of the first triode, to realize the reliable regulation of the power supply voltage by the transformer, and to stabilize the output voltage through the third diode and the fourth diode, which improves the stability of the output voltage Not only that, but in the audio input circuit, the LC series resonant circuit is connected to the emitter of the second triode to make up for the high frequency loss during the recording process and improve the reliability of the system.

Description

technical field [0001] The invention relates to the field of BIM technology, in particular to an indoor multimedia system based on BIM technology. Background technique [0002] Building Information Modeling (Building Information Modeling) is based on the relevant information data of the construction project as the basis of the model to establish the building model, and simulate the real information of the building through digital information simulation. It has five characteristics of visualization, coordination, simulation, optimization and plotting. [0003] BIM covers geometry, spatial relationships, geographic information systems, properties and quantities of various building components (e.g. supplier details). Building information modeling can be used to represent the entire building life cycle, including the construction process and operation process. It is very convenient to extract the information of the materials in the building. Each part and each system in the b...

Problems solved by technology

In the existing multimedia system, the input power supply is stabilized by the internal voltage regulator transistor, and the stable working voltage is output to provide to the system to realize its stable operation. However, the loss of the power supply voltage is relatively high, and , when the input power is high, it is easy to burn out the triode; not only that, in the multimedia system, in the process of collecting the input audio, there will often be a high-frequency loss on the recording head, which reduces the reliability of the recording, thereby reducing system reliability
