Intelligent door lock adopting HDMI display screen
The invention discloses an intelligent door lock adopting an HDMI (High Definition Multimedia Interface) display screen. Theintelligent door lock comprises a front lock plate arranged outside a door, a rear lock plate arranged inside the door and a lock body and a lock cylinder arranged in a door plate; a video mainboard is arranged in the front lock plate, one side of the video mainboard is connected with a camera, and the other side of the video mainboard is provided with a first HDMI interface; an interface adapter plate is arranged in the rear lock plate, one side of the interface adapter plate is connected with a display screen, and the other side of the interface adapter plate is provided with a second HDMI interface; an HDMI transmission line is inserted between the first HDMI interface and the second HDMI interface, and the video mainboard is connected with the interface adapter plate through the HDMI transmission line. According to the invention, the HDMI interface and the HDMI transmission line are adopted to transmit the video signal without adding an additional conversion chip and performing protocol conversion on the interface signal of the display screen, the transmission line is low in line loss and small in interference, the video signal can be ensured to be transmitted to a distance of more than 50cm, and the signal transmission distance requirement and the signal transmission quality of the display screen are met.
本发明公开了一种采用HDMI接口显示屏的智能门锁，包括设于门外的前锁板、设于门内的后锁板以及安装在门板内的锁体锁芯，前锁板内设有视频主板，视频主板的一侧连接有摄像头，视频主板的另一侧设有第一HDMI接口；后锁板内设有接口转接板，接口转接板的一侧连接有显示屏，接口转接板的另一侧设有第二HDMI接口；第一HDMI接口和第二HDMI接口之间插接有HDMI传输线，视频主板通过HDMI传输线与接口转接板连接。本发明在不增加额外的转换芯片，且不对显示屏的接口信号进行协议转换的情况下，采用HDMI接口和HDMI传输线进行视频信号的传输，该传输线的线路损耗较低，且干扰较小，能够保证视频信号可传输到50cm以上的距离，满足显示屏的信号传输距离要求和信号传输质量。
