摘要壁炉起源于国外，大多数都只是单面性。为了适应市场艺术需求，本文对仿 真火壁炉声光电系统进行了设计。

首先，本文对壁炉的仿真功能进行设计。火焰部分使用灯光、旋转式反射片 模拟动态火焰；声音部分采用 ISD1820 录音、放音，模拟木炭燃烧的声音；加热 部分采用 PTC 陶瓷发热体发热，模拟壁炉火燃烧的热量。73825

然后，在外观造型的基础上进行仿真壁炉的内部结构设计，其中包括初步尺 寸设计、部件之间的连接，以及动态火焰的光学实现原理分析。

最后，本文还对仿真壁炉控制系统进行了硬件设计、软件设计。 通过仿真火壁炉声光电系统设计，从外观到内部结构，本文实现了 360 度观

赏和模拟。

Sound and light simulation fire fireplace system design

Abstract Fireplace originated from foreign countries, most of them are only one-side. In order to meet the market demand of art, this article has carried on artificial simulation fireplace about acoustic and photoelectric systems design.

First of all, this article design the artificial simulation of the fireplace. Flame uses light, rotating reflector to simulate dynamic flame; Voice adopts ISD1820 recording, playback, simulating the voice of charcoal burning ;The heating adopts the PTC ceramic heating body to heat, and the heat of the fire burning in the fireplace is simulated.

Then, on the basis of the external appearance, the internal structure of the simulation fireplace is designed, including the connection between the preliminary design, components, and analysis of optical realization principle of dynamic flame.

Finally, the hardware design and software design of the control system of the artificial simulation fireplace are also carried out.

Through the artificial simulation fireplace about acoustic and photoelectric systems design,the paper realizes 360 degree viewing and simulation from the exterior to the internal structure.

Key words:electric fireplace sound and light system ceramic heating element
