This application discloses a clock synchronization method, apparatus, board, and computer-readable storage medium, relating to the field of network time synchronization technology. The service card encapsulates a device sending timestamp in a first NTP request message sent by the main control card based on the first current service system time to obtain a second NTP request message, which is then sent to the NTP server. Based on the second current service system time, the service card encapsulates a device receiving timestamp in a second NTP response message sent by the NTP server to obtain a first NTP response message. The first NTP response message is then sent to the main control card, allowing the main control card to calculate the network clock deviation between itself and the NTP server based on the first NTP response message, and adjust the main control system time accordingly. This method avoids the problem of large errors between the device sending timestamp and the device receiving timestamp, thus ensuring that the network clock deviation calculated by the main control card will not have significant errors.

This invention discloses a hybrid network clock synchronization system based on a master-slave architecture, comprising a master unit and at least one slave unit. The master unit includes a first microprocessor, a Wi-Fi communication module, and a first BLE communication module. The slave unit includes a second microprocessor, a second BLE communication module, and a clock display module. The first microprocessor of the master unit accesses the network via the Wi-Fi communication module to obtain network clock data and environmental weather data. It extracts core fields from the data, encapsulates them into a synchronization data packet containing a feature identification code and payload data, and controls the first BLE communication module to send this synchronization data packet to the slave unit. The second microprocessor of the slave unit receives the synchronization data packet via the second BLE communication module, parses the payload data according to a preset decoding mapping table and the feature identification code, obtains the synchronization time value and weather parameters, thereby updating local data and controlling the clock display module to refresh the display. This effectively solves the technical problems of edge node computing power overload and excessive network energy consumption.

Disclosed in the present invention is a time synchronization method for network nodes. The method specifically comprises: determining a master node and slave nodes in a network; periodically detecting a frequency offset rate Rf of each slave clock relative to a master clock and a transmission delay Ndelay between the master node and each slave node, and correcting a current timestamp of the slave clock on the basis of a current timestamp of the master clock, thereby realizing synchronization between the slave clock and the master clock. By providing a master clock having high clock precision in a network, the time of a slave clock is periodically calibrated on the basis of the master clock, so that while the clocks of nodes in the network are kept basically synchronized, the cost required to keep the clocks in the network basically synchronized is also relatively low.
