The invention relates to an electric monitor system and a computer class equipment fault solution of an electric monitor system. The hardware redundancy of the computer equipment is realized through virtual machine technology, a virtual machine can perform the failover when any physical machine is in hardware fault after the deployment is accomplished, and the running of application software cannot be influenced. The solution comprises the following steps: a redundancy network based on PRP or HSR technology is constructed, and the normal running of the system cannot be influenced even if any line in the network is in fault damage by using the PRP or HSR technology principle; the related device is accessed to the constructed redundancy network through the PRP/HSR conversion equipment, thereby accessing the device not supporting the redundancy network at first to the redundancy network. Therefore, the redundancy function is configured for the original single computer equipment under thecondition of unchanging the application program and configuration of the existing computer equipment, the single point fault of the network is processed through the PRP/HSR technology, and the hardware single point fault is processed through the virtual machine technology.
