After the dual main control device is powered on, it enters the normal working mode; the main main control board loads system and application information from the shared storage device (the main main control board is connected to the shared storage through a high-speed strobe switch by default), and updates the user's latest target in real time configuration information to a shared storage device. The standby main control board does not receive the heartbeat signal from the main main control board for a certain period of time t2. Then the main main control board is faulty by default. At this time, the high-speed strobe is turned on to disconnect the connection between the main control board and the shared storage; at the same time, the connection between the standby main control board and the shared storage is selected. At the same time, the standby main control board exits the low power consumption mode, and stores user data in the onboard storage device. The standby main control board loads system and business information from the shared storage, and at the same time quickly loads the latest user configuration information and task information. At this point, the standby main control board actively enters the service mode. Then the standby mainboard transfers the data stored onboard to the large-capacity storage on the backplane to solve the problem of real-time data storage loss during active-standby switchover. At this time, the standby main control board has taken over all business information, that is, the active/standby switchover has been seamlessly completed.

According to the present invention, the dual-control device includes a main and main control device, a backup and main control device, and a storage device. The main control device is connected to the main control device, which is used to connect to the storage device when the main control device is determined to be faulty, obtain target configuration information, system files and application information from the storage device, and load system files and applications. information and target configuration information.

Inform the standby main control board that the whole machine is working normally, and the standby main control board is in a low power consumption state. After the standby main control board receives the heartbeat signal, it needs to return a confirmation message to inform the main main control board that the function and performance of the standby main control board are normal. Make sure that the communication between the master and backup is normal. If the data communication interval between the main main control board and the standby main control board is greater than the preset time, then increase the heartbeat signal sending frequency. For example, if the main main control board does not receive a confirmation signal from the standby main control board within X seconds, it is considered that the communication between the main and standby main control boards has not been established yet, and the frequency of sending new jump signals needs to be increased. If the data communication interval between the main main control board and the standby main control board is less than the preset time, keep the sending frequency of the heartbeat signal unchanged. If the main main control board fails to establish communication with the standby main control board after a certain time threshold, it is considered that the standby main control board does not exist or is faulty, and the user is reminded to confirm.
