The invention discloses a heartbeat detection method of an SCADA distribution type platform. A heartbeat sending thread and a heartbeat receiving thread are coordinated to carry out fault detecting, the sending thread sends heartbeat to target nodes, and the state of the nodes is detected by judging the maximum number of losing times of the heartbeat; the receiving thread is used for receiving the heartbeat and replies when normally receiving the heartbeat, and otherwise the maximum number of losing times of the heartbeat adds one. Under the situation that the network state is busy, the heartbeat sending thread and the heartbeat receiving thread pause, a command packet is used for replacing the heartbeat to detect the state of the nodes, and the network resource can be saved. According to the heartbeat detection method, the availability of a system can be greatly improved, and the misjudgement rate of node faults is decreased.
