Embodiment Construction

[0039] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0040] Such as figure 1 A dual-terminal mutual display system for a locomotive shown includes a local subsystem and a remote subsystem respectively placed at both ends of the locomotive. Each subsystem has the same structure and includes a video monitoring host, which is connected to the Display and network switch, the network switch is used to connect the surveillance camera at the corresponding end of the locomotive.

[0041] Each video monitoring host computer includes a control board and an NVR board. The control board includes a CPU. The CPU is connected to a voice switching circuit and a video switching circuit. The CPU is connected to the RS485 serial interface of the NVR board through the RS485 serial bus. RS485 line communication connection display.

[0042] In order to realize the connection between the video surveillance hosts i...

Abstract

The invention relates to a double-end mutual display system and a video monitoring host for a locomotive, and belongs to the technical field of locomotive video monitoring. The double-end mutual display system provided by the invention is provided with subsystems (a local end subsystem and an remote subsystem), a video monitoring host is arranged in each subsystem, and each video monitoring host is correspondingly provided with a display, thereby reducing the information processing burden and relatively improving the display effect. Moreover, the double-end mutual display system provided by the invention switches between audio and video recorded by a local monitoring camera of the locomotive and the audio and video recorded by a remote monitoring camera of the locomotive through a voice switching circuit and and a video switching circuit that are disposed, and the subsystem of either end can perform repeated switching of the audio and video to realize the linkage of the audio and video.

Description

technical field [0001] The invention belongs to the technical field of locomotive video monitoring, and in particular relates to a dual-terminal mutual display system and a video monitoring host for locomotives. Background technique [0002] In the locomotive industry, there is a demand that in order for the crew to grasp the situation of the locomotive, it is necessary to be able to view the surveillance video at both ends of the locomotive at any end of the locomotive. [0003] In order to realize this requirement, a common way is to divide the video signal into two paths by a video surveillance host computer and provide them to two displays respectively. This kind of video monitoring host needs to process all the monitoring information, which has a large burden, poor processing effect, and slow response speed, resulting in poor display effect. Dividing the video output line into two channels and providing them to two monitors As a result, the displayed video image is eas...
