the fault detection module is used for detecting the working state of the main server and controlling the working task to be switched between the main server and the backup server according to the working state of the main server.
5. The dual hot standby system according to claim 4, wherein the networking pairing module comprises a server discovery unit and a server authentication unit;
the server discovery unit is used for searching candidate servers matched with the main server within a preset range;
the server authentication unit is used for determining a candidate server which has an authentication relation with the main server from the candidate servers as the backup server.
6. The dual-engine hot standby system according to claim 4, wherein the data transmission module comprises a data encryption and decryption unit and a link management unit;
the data encryption and decryption unit is used for performing encryption and decryption operations on the main data and the backup data;
the link management unit is configured to determine the target link for synchronizing the primary data with the backup data.
7. The dual-machine hot standby system according to claim 4, wherein the fault detection module comprises a heartbeat management unit, a fault detection and recovery unit and a primary-standby switching unit;
the heartbeat management unit is used for maintaining heartbeat signals between the main server and the backup server;
