Method, system and device for clock synchronization in human-machine-environment data acquisition and medium

A method for clock synchronization in human-machine-environment data acquisition, executed by a second device, comprising:

• initiating a human-machine-environment data acquisition task within a local area network of the second device, so that at least one first device acquires the human-machine-environment data acquisition task, wherein the at least one first device and the second device are located in a same local area network;
• performing message interaction with the at least one first device, so that the at least one first device obtains timestamps during a message interaction process, and determines a time offset of the at least one first device relative to the second device based on the timestamps, wherein the timestamps comprise clock information of the second device, and the clock information of the second device is a calibration clock for a current acquisition task;
• receiving first human-machine-environment data and a calibration moment bound with the first human-machine-environment data sent by the at least one first device, wherein the first human-machine-environment data is collected by the at least one first device and/or at least one data collector connected to the at least one first device, the at least one data collector is configured to collect human-related data, machine-related data, and/or environment-related data, and the calibration moment bound with the first human-machine-environment data is a moment obtained by the at least one first device calibrating an acquisition moment of the first human-machine-environment data acquired by the at least one first device based on the time offset;
• and
• aligning the first human-machine-environment data with second human-machine-environment data acquired by the second device based on the calibration moment bound with the first human-machine-environment data, wherein the second human-machine-environment data is collected by the second device and/or at least one data collector connected to the second device.
