Network-based dual-computer mutual backup automatic takeover method and device, and storage medium

The invention provides a network-based dual-computer mutual backup automatic takeover method and device, and a storage medium. The method comprises the following steps: setting a heartbeat timer; in the timing process of the heartbeat timer, monitoring whether first heartbeat information sent by the mutual standby equipment is received or not; and if the first heartbeat information is still not received after the heartbeat timer is up, taking over the work of the mutual standby equipment. The method comprises the following steps: monitoring whether first heartbeat information sent by mutual standby equipment is received or not in a timing process of a heartbeat timer; and if the first heartbeat information is still not received after the heartbeat timer is up, the work of the mutual standby equipment is taken over, so that automatic take-over is realized, logic confusion caused by confusion of a dual-computer mutual standby automatic take-over function code and a service code realized by each software is avoi
