[0001] The present invention relates to the technical field of data pairing and synchronization, and in particular to a multi-terminal data pairing and synchronization method and system. Background Art

[0002] The field of data pairing and synchronization technology involves technologies and methods to ensure data consistency and synchronization between different devices or systems, including the design of data synchronization algorithms, data consistency strategies between multiple devices, and network communication protocols to achieve data synchronization. Data pairing and synchronization technology enables users' data to be updated and consistent between multiple terminals, such as mobile data, portable recording data, and other recording data (drones), thereby supporting seamless data access and real-time information updates. It is widely used in cloud services, distributed computing, and mobile device management, and is an indispensable part of modern communications and information technology.

[0003] Among them, the multi-terminal data pairing synchronization method refers to a technical method to ensure data consistency and synchronization between multiple computing devices. It achieves synchronization by automatically comparing and updating data between different devices, so that the user's operations on any one device can be reflected on other devices. The main uses include personal data management, data synchronization of cross-platform applications, and enterprise-level data consistency assurance, such as ensuring that work documents, contact information, schedules and other data are kept up to date on employees' multiple devices.

[0004] In the prior art, data synchronization between multiple devices usually relies on central servers or cloud services. This reliance can easily lead to network delays and processing bottlenecks, especially in large-scale data synchronization needs. The lack of a real-time correction mechanism is particularly evident when dealing with inconsistent timestamps between devices, leading to data consistency issues and reducing the authenticity and reliability of the data. For example, in an environment without network coverage, the prior art often cannot guarantee timely synchronization of data, thereby increasing the risk of data loss or errors.

[0023] See also Figure 2 , the specific steps of S1 are: S101: The terminal device is physically close to the target, paired with the NFC module, synchronously starts the physical communication link, exchanges signals with the target device, detects signal strength and quality, and records and obtains an initial timestamp record; When the terminal device is physically close to the target and paired with the NFC module for signal transmission, the device first starts the physical communication link through high-precision time synchronization technology, and exchanges signals with the target device through the NFC communication module. This process involves monitoring and evaluating the signal strength and quality. To this end, the system records the strength and quality data of the received signal, and records the initial timestamp of the acquired signal in real time. This data is crucial for analyzing communication efficiency and speed. Within the effective distance of the NFC module, the detection of signal strength and quality ensures the reliability of data transmission. By establishing and maintaining the physical link, the continuous and stable transmission of the signal is ensured. The communication efficiency and response time between devices directly affect the operating efficiency of the entire system. Recording the initial timestamp is to further analyze the time synchronization and data exchange efficiency between devices.

[0024] S102: Based on the initial timestamp record, compare the timestamp differences of the devices, identify the maximum and minimum time deviations, calculate the average deviation value, perform system adjustments on the device time, and generate a time synchronization status record; Compare the timestamp differences of the devices, according to the formula , calculate the average deviation value.

This operation is achieved through a precise time synchronization algorithm to ensure that all devices can process and exchange data based on completely synchronized time. This is crucial to maintaining efficient collaboration among components within the system. The execution of overall synchronization of time standardization not only improves the operating efficiency of the system, but also reduces the delay in the data processing process. Ultimately, through this series of operations, the efficient collaboration of the entire system is ensured, and the setting of a unified time reference provides an accurate time reference for each task in the system, thereby greatly improving the accuracy and efficiency of the overall operation.

This formula ensures that all data records are synchronized with a unified time base, reducing the impact of time errors on data analysis. For example, if seconds, and seconds, then the time deviation It is 2 seconds, which means that the actual acquisition time is 2 seconds faster than the reference time.

By calculating the difference, it is possible to specify the amount by which the timestamp of each data item needs to be adjusted. Correction is essential for subsequent data analysis to ensure that all data items are strictly aligned to a unified time base.
