Video signal acquisition and recording device and long-distance high-definition laser camera

Abstract

The invention discloses a video signal acquisition and recording device, comprising: a collecting and editing device and a memory, wherein the collecting and editing device adopts a digital signal processor, a programmable logic device and a secondary module optimization technology of a compression arithmetic coding structure; and the memory is a high-speed, large-capacity solid-state recorder forreal-time image and video signal data storage. The present invention also provides a long-distance high-definition laser camera, which adopts the optical selective filtering technology and the electronic photoelectric saturation suppression technology, tackles a variety of stray light in a complex terrain environment, has a zoom lens with an aspheric maximum of 60 times and continuous magnification of 1.2 to 80mm, and achieves the overall process image acquisition, movement point calculation and identification and output of the optical axis fine-tuning system, so that the video image data acquisition of the monitoring area, the automatic processing of the laser tracking image and the continuous tracking of the target at a close distance and wide-range angle are achieved.

Description

technical field [0001] The invention relates to the technical field of railway monitoring, in particular to a video signal collection and recording device and a long-distance high-definition laser camera. Background technique [0002] With the formation of the eight-vertical and eight-horizontal high-speed rail network, the operation of high-speed rail EMUs continues to extend to the southwest and northwest regions. The Guizhou-Guangzhou high-speed railway-Guizhou section reaches 92%), the environment around the high-speed railway hub has various complex geological structures, topographical climate environment, engineering geology and hydrogeological conditions, and the influence of various adverse geological effects and the scope and level of influence of hazards, The threat to the safety of the operating area and the surrounding area is increasing, and high-speed EMUs put forward almost strict requirements for the high ride comfort, high stability, and high precision neces...

Problems solved by technology

However, due to the complex geographical environment in the western region, the influence of geological disasters, topographical climate, thunder, lightning, rain and fog, etc., it is impossible to monitor and prevent real-time monitoring and prevention of long lines and wide line areas, and the hazards are mostly without warning (the latent nature of geological disasters or geological hazards that have not been discovered by people) occur, and various safety hazards still exist, which requires on-site duty and patrol personnel to be vigilant all the time, early detection, early prevention, and early disposal

[0003] The cameras in the prior art will be interfered by various light sources, especially the strong light of the car lights, which will cause problems such as unclear imaging around the clock. If the inspection is not in place, it will easily lead to misjudgment. It will definitely have a serious impact on traffic safety monitoring, safe operation, and safe implementation of reliability guarantees on rail station roads and operating intervals
