Time frequency synchronization method and system, storage medium and electronic equipment

The invention discloses a time frequency synchronization method and system, a storage medium and electronic equipment. The method comprises the following steps: acquiring a master node sending timestamp, a slave node receiving timestamp, a slave node sending timestamp and a master node receiving timestamp; acquiring a first phase difference between the local clock signal of the master node and the received data stream recovery clock signal, and acquiring a second phase difference between the local clock signal of the slave node and the received data stream recovery clock signal; performing phase calibration on the timestamps received by the master node, and performing phase calibration on the timestamps received by the slave nodes; obtaining a time deviation between the slave node and the master node according to the master node sending timestamp, the calibrated slave node receiving timestamp, the slave node sending timestamp and the calibrated master node receiving timestamp; and performing time compensation
