The invention discloses a method, apparatus and equipment of time synchronization of a redundancy monitoring network, and a computer readable storage medium. The method of time synchronization of a redundancy monitoring network includes the steps: determining whether a first monitoring network is in the normal operation state; when the first monitoring network is in the normal operation state anda second monitoring network is in the standby state, sending clock source setting parameters to the first monitoring network, so as to enable the first monitoring network to set the self clock parameters according to the clock source setting parameters; and through a preset communication link between the first monitoring network and the second monitoring network, sending the clock source setting parameters acquired by the first monitoring network to the second monitoring network, so as to enable the second monitoring network to set the self clock parameters according to the clock source setting parameters. The method, apparatus and equipment of time synchronization of a redundancy monitoring network, and the computer readable storage medium can correctly ensure accuracy of monitoring the network time by means of the whole cabinet server.
