基于WiFi传输的电梯视频采集器设计

摘要

A WiFi-based elevator video capture device is designed for the special environment of elevator hoistway. The design uses a CCD camera as a video capture terminal, TVP5150 as a decoding and converting chip. After S3C6410 microprocessor’s encoding, the video images are transmitted through WiFi wireless network. The design implements the high-speed continuous data acquisition of elevator car’s video image, and overcomes the inadequacy of traditional wired elevator video acquisition. Moreover, due to the characteristics of flexible networking, low cost and easy expansion, the design will have a good application prospect.%针对电梯井道的特殊环境，设计了一种基于WiFi传输的电梯视频采集器。该设计采用CCD摄像头作为视频采集端，经过视频解码芯片TVP5150的解码和转换后，利用S3C6410微处理器对视频信号进行压缩编码，最后通过WiFi无线网络实时传输视频图像。该设计实现了电梯轿厢视频图像的高速连续采集，克服了传统电梯视频有线采集的不足，且组网灵活、成本较低、易扩展，具有良好的应用前景。
