This invention discloses a method for fixed-delay playback and seamless switching of live streams based on absolute time stamps, comprising the following steps: S1: Receive an HTTP-FLV data stream, append an absolute time stamp (absolute_time) to each Tag object, and store the Tag objects in a circular buffer queue; S2: Determine the playback time and locate the Tag object to be sent based on the absolute time stamp (absolute_time); S3: Rewrite the timestamp of the Tag object to be sent, encapsulate it, and send it to the player client; S4: Upon receiving a switching command to switch the current playback stream to the target playback stream, seamlessly switch to the target playback stream for playback. This invention's method for fixed-delay playback and seamless switching of live streams based on absolute time stamps can achieve precise fixed-delay playback of live streams and seamless switching between multiple live sources without full-stream transcoding.

The application discloses a geological radar detection water conservancy and hydropower tunnel backfill grouting quality operation platform and belongs to the technical field of geological detection. The operation platform comprises an operation frame, a central shaft arranged on the operation frame, an intermediate cylinder coaxially connected with the central shaft, a radar antenna arranged in the middle part of the intermediate cylinder, and a damping assembly connecting the central shaft to the operation frame. The outer side of the intermediate cylinder is coaxially provided with a protective cylinder. The protective cylinder comprises arc-shaped protective plates, flexible connecting belts, first outer rods, first inner rods, first damping springs and rotating rings. The arc-shaped protective plates are annularly and uniformly distributed on the outer side of the intermediate cylinder. The arc-shaped protective plates are connected in an integrated manner through the flexible connecting belts. The rotating rings are rotatably arranged on the outer side of the intermediate cylinder. The device can effectively protect the geological radar when the radar is smoothly detected, effectively avoids the radar jumping problem caused by interference, and enables the detection process to be smoothly performed.
