The invention relates to the technical field of industrial data processing, and provides an industrial heterogeneous data processing system for multi-protocol conversion through a state machine, which comprises a first finite-state machine and a second finite-state machine which are configured in advance; wherein the first finite-state machine is configured with a configurable protocol stack triggered by different industrial heterogeneous data, and the second finite-state machine is configured with a communication interface set triggered by different conversion protocols; when the first finite-state machine receives to-be-processed industrial heterogeneous data, determining a target processing server and a data type; triggering a corresponding target communication protocol in a configurable protocol stack according to the data type; after the target communication protocol is triggered, according to the target processing server, centrally triggering a corresponding target data interface to be docked with the target server through the communication interface of the second finite-state machine; wherein the target data interface is not unique.

The invention relates to the technical field of disaster recovery, and discloses a data backup system and method, a medium and a program product. The system comprises the steps that a snapshot establishment request is sent to a virtual resource management node through a backup control module, a bitmap volume establishment request is sent to a backup module after a current snapshot volume is established, and data backup configuration information is sent to the backup module when a bitmap volume establishment completion response is received; when a backup module receives a bitmap volume establishment request, according to a backup type, a bitmap volume establishment instruction is generated and sent to FusionStorage for storage, after a current bitmap volume is established, a bitmap volume establishment completion response is sent to a backup control module, and when data backup configuration information is received, the current bitmap volume establishment completion response is sent to the backup control module. And performing data backup on the virtual machine to be backed up according to the data backup configuration information, the current snapshot volume and the current bitmap volume. According to the scheme provided by the embodiment of the invention, the backup of the data stored in the FusionStorage can be realized, and effective data protection can be carried out on the virtual machine stored in the FusionStorage.

The invention discloses a disk data backup method of a virtual machine, a server and a storage medium, which are applied to a first server, and the first server supports a VMware virtual machine function. The method comprises the steps that a disk backup identifier sent by a second server is received, a first instruction is sent to a VMware server, the disk backup identifier is obtained by a third server from the VMware server and forwarded to the second server, and the first instruction comprises a disk identifier of a disk to be backed up and the disk backup identifier; obtaining disk data corresponding to a disk backup identifier in a to-be-backed-up disk determined by the VMware server according to the disk identifier; and sending the disk data to the second server. According to the invention, data transmission and data backup between heterogeneous servers can be realized.

The invention belongs to the technical field of iron core grounding current monitoring of transformers, and particularly relates to an iron core grounding current recording method based on precise time synchronization. Comprising the following steps: collecting a current signal through an iron core and a clamp grounding current sensor; time deviation caused by RTC is calibrated continuously in the collection process; performing cyclic sampling and calculation on an output signal of the sensor, sending total current and multiple harmonic waves obtained by Fourier calculation to a display end of an upper computer, and starting fault recording when the value of the total current meets a fault judgment threshold value; when it is judged that a fault occurs, an accurate time mark is provided through an accurate time synchronization function, reserved historical data and collected real-time data are spliced into a wave recording graph during the fault period, and the wave recording graph is backed up and transmitted to a display end of an upper computer to be stored and displayed. According to the invention, some fault phenomena which are short in duration and rapid in generation and disappearance can be effectively monitored, and the change trend of iron core and clamp current when faults occur can be effectively monitored.
