Method for accurately aligning time among multiple terminals of timing sports test system

Abstract

The invention provides a method for accurately aligning time among multiple terminals of a timing sports test system. The invention belongs to the field of time alignment among multiple terminals in an information system, and particularly relates to a method for time alignment among terminals with various types of different platforms in a timing physical test system. The method comprises the following steps: step 1, sending a network delay test request; step 2, sending a network delay test response; step 3, calculating calibration time; step 4, sending a calibration time request; and step 5, calibrating time. The method for accurately aligning the time among the multiple terminals in the timing type physical test system is effectively realized, so that synchronous starting, synchronous timing and synchronous score calculation of project tests can be realized among the multiple terminals of the timing type physical test system.

Description

technical field [0001] The invention belongs to the field of time alignment among multiple terminals in an information system, and in particular relates to a method for aligning time between terminals of various types and platforms in a timing sports test system. Background technique [0002] The main task of accurate time alignment between multiple terminals in the timing sports test system is to achieve consistent time among multiple terminals in the timing sports test, so that multiple terminals can start, time and calculate sports test results synchronously. [0003] For example, in the intelligent 1000-meter sports test system, the system includes system service background device D1, video analysis engine device D2, WEB terminal device D3, Android tablet terminal device D4, and iPad terminal device D5. The device D2 is responsible for intelligently analyzing the video, and broadcasts the analysis results to D3, D4 and D5 through the device D2. In this embodiment, the d...
