This invention discloses a PDA computer network isolation topology optimization system and method in the field of network communication. The system includes a network switching unit comprising a backbone switch and an isolation switch, a control unit comprising an industrial controller, a terminal unit comprising at least one PDA computer, and a fault diagnosis unit comprising a fault verification module configured within the isolation switch and the backbone switch. The static IP address of the PDA computer is located in the firewall whitelist of the industrial controller. The PDA computer network isolation topology optimization system provided by this invention achieves physical isolation between the PDA computer and the real-time industrial Ethernet bus by setting up an isolation switch between the PDA computer and the backbone switch. This ensures fault isolation when the PDA computer fails, preventing impact on other devices. Furthermore, the fault verification module within the isolation switch and the backbone switch allows for rapid fault location, improving fault repair efficiency.

The application discloses a kind of judging method and device of fault migration, when receiving the fault information of host computer, the fault detection of switch is carried out;When the switch corresponding to host computer is detected and the fault record table does not contain the fault information of host computer, the fault detection of the port of switch is carried out;When the port of the switch corresponding to host computer does not fail, login detection is carried out to host computer;If host computer does not pass login detection, the fault information of host computer that has initiated fault migration in target time period is obtained from fault record table;When the number of fault information of host computer is not greater than preset maximum number, then trigger virtual machine to carry out fault migration.When receiving the fault information of host computer, host computer will be detected again.If confirming host computer failure, the number of triggering fault migration in a certain time will also be limited, only in the case of meeting the condition, fault migration will be carried out, to effectively avoid large-scale mismigration.

The invention relates to a computer fault prediction method based on an ARCH model and a Kalman filter, and belongs to the field of data prediction. The method comprises the following steps of data preparation and preprocessing, ARCH model establishment and parameter estimation, volatility prediction, Kalman filter establishment, volatility correction and anomaly prediction and detection. According to the method, by predicting the volatility of the key current and voltage of the computer mainboard, abnormal conditions possibly occurring in a period of time in the future can be found in time, then processing is carried out in advance before faults occur, and service interruption caused by sudden computer faults is greatly reduced. The method is mature in principle and easy to implement, has certain universality and is suitable for other similar data prediction occasions.

The invention relates to the technical field of electronic information, and discloses a computer fault detection method, device and equipment and a storage medium, and the method comprises the steps: printing a computer starting log through a Flash chip, analyzing the starting log through a single-chip microcomputer, analyzing a fault position through the single-chip microcomputer according to the log content, sending an instruction to a nixie tube, and according to the error information displayed by the nixie tube, sending an instruction to the computer; and computer hardware is reinstalled, so that the problem that the computer cannot be normally started is solved. When the reinstalled hardware is invalid, the fault position is accurately positioned through the log information printed by the serial port tool, so that the reason that the computer cannot be normally started is positioned, and the problem that the computer cannot be normally started due to inaccurate positioning of the fault position can be solved.
