Referring to fig. 2, fig. 2 is a flow chart illustrating a data synchronization method according to an embodiment of the invention. In this embodiment, the data synchronization method includes:
s202: historical diagnostic data is acquired based on a preset time period, and the historical diagnostic data is latest running state information of the control system stored in a database.
Illustratively, a preset time period is set, and historical diagnosis data is acquired based on the preset time period, wherein the historical diagnosis data comprises the diagnosis data which is stored in a database of other servers except the target server and is closest to the current time, and the diagnosis data comprises the running state information of the whole control system. Specifically, all diagnostic data of a server in the control system are obtained and cached, a diagnostic data queue is obtained based on time sequence, and the latest diagnostic data in the diagnostic data queue is further used as historical diagnostic data.
S204: and acquiring real-time diagnosis data, wherein the real-time diagnosis data is the running state information of the control system acquired by the target server.
Illustratively, real-time diagnosis data of the current time is acquired, wherein the real-time diagnosis data comprises the current operation state information of the control system acquired by the target server. Specifically, a control instruction is sent to a target server, and the target server is controlled to acquire and send real-time diagnosis data; and receiving the real-time diagnosis data sent by the target server.
S206: and judging whether the time interval between the historical diagnostic data and the real-time diagnostic data exceeds a preset time period, if so, determining the real-time diagnostic data as synchronous data, and performing data synchronization.
Illustratively, corresponding time information is acquired based on historical diagnostic data and real-time diagnostic data respectively, a time interval between the historical diagnostic data and the real-time diagnostic data is determined based on the time information, whether the time interval exceeds a preset time period or not is further judged, and if the time interval exceeds the preset time period, the real-time diagnostic data is taken as synchronous data to perform data synchronization. It can be understood that, if the time interval exceeds the preset time period, it indicates that the acquisition time of the historical diagnostic data and the acquisition time of the real-time diagnostic data are not in the same time period, and at this time, the real-time diagnostic data needs to be used as synchronous data, so as to synchronize the diagnostic data in the control system. The real-time diagnosis data and the historical diagnosis data have time stamps, namely the time for acquiring the diagnosis data, and the time information of the real-time diagnosis data and the historical diagnosis data is determined based on the time stamps.
In one specific embodiment, other servers except the target server only perform data communication with the target server, and the data synchronization method in the embodiment ensures that the diagnostic data in the local server is consistent with the real-time diagnostic data of the target server. Specifically, the other servers send data synchronization requests to the target server, and the target server receives and processes the data synchronization requests, acquires real-time diagnostic data, and returns the real-time diagnostic data to the other servers.
In another specific embodiment, a time stamp of historical diagnostic data and a time stamp of real-time diagnostic data are obtained, where the time stamp is in a unit of a preset time period, and may be 1 s; and judging whether the time tag of the historical diagnostic data is later than that of the real-time diagnostic data, if so, judging that the historical diagnostic data is invalid, and further taking the real-time diagnostic data as synchronous data.
Alternatively, the synchronization period of the setting data is 1s, and the diagnostic data packet transmission period in the control system may be set based on software. When a plurality of diagnostic data are processed in one synchronization cycle, there may be a conflict between the diagnostic data, resulting in a reduction in the time of the fail-over period. To ensure that the fault trigger cycle coincides with the data synchronization cycle, only one diagnostic data is processed in each cycle. For example, when two diagnostic data exist in the same synchronization period, i.e. the packet transmission period of the control system is 500ms, only the diagnostic data between 1-500ms is accepted, and the diagnostic data within 500-1000ms is discarded, thereby avoiding processing different real-time diagnostic data in the same time period.
Optionally, the control device, the server, the client, and other devices in the control system all have a time synchronization function, and time information of the whole system is synchronized through the time synchronization functions of different devices, so that all device times of the whole system are ensured to be in a synchronization state.
The method includes the steps that historical diagnosis data are obtained based on a preset time period, and the historical diagnosis data are latest running state information of a control system stored in a database; acquiring real-time diagnosis data, wherein the real-time diagnosis data is the running state information of the control system acquired by a target server; and judging whether the time interval between the historical diagnostic data and the real-time diagnostic data exceeds a preset time period, if so, determining the real-time diagnostic data as synchronous data, and performing data synchronization. The time interval of the historical diagnostic data and the real-time diagnostic data is judged, and the real-time diagnostic data of which the time interval exceeds a time period is further determined as synchronous data, so that the synchronous data in each server is always the latest running state information of the control system, the technical problem that the time information displayed in different control software and the running state of the system are not consistent in the prior art is solved, the time information of different servers and the running state of the system are consistent, and the diagnostic accuracy of the control system is improved.
In another embodiment, the obtaining real-time diagnostic data further comprises:
and if the real-time diagnosis data are failed to be acquired, taking the historical diagnosis data as synchronous data to carry out data synchronization.
Illustratively, after the operation of acquiring the real-time diagnostic data is performed, it is determined whether the real-time diagnostic data is successfully acquired. And if the real-time diagnosis data cannot be acquired, taking the historical diagnosis data as synchronous data. It is understood that since there is no current real-time diagnostic data, the historical diagnostic data closest to the current point in time is taken as the synchronization data.
In one embodiment, the preset time period is set to 1s, and the data synchronization operation is performed every 1 s. If the real-time diagnosis data is not acquired, the time stamp of the historical diagnosis data is increased by 1s to be used as the time stamp of the period, at the moment, the historical diagnosis data is synchronous data, namely the historical diagnosis data of the last preset perfect period is used as the synchronous data of the current period.
In this embodiment, if the real-time diagnostic data fails to be acquired, the historical diagnostic data is used as the synchronization data to perform data synchronization. When the control system has an unexpected condition and cannot acquire real-time diagnosis data, the historical diagnosis data of the previous preset time period is used as synchronous data, so that the continuous operation of data synchronization is ensured, and the stability of the control system is improved.
In another embodiment, determining the real-time diagnostic data as the synchronization data further comprises:
step 1: analyzing the synchronous data;
step 2: and judging whether the analysis result meets preset conditions or not, if not, judging that a fault exists in the control system, and outputting fault prompt information, wherein the preset conditions at least comprise network load conditions and network communication conditions.
Illustratively, after the synchronous data are acquired, the synchronous data are analyzed according to a data analysis protocol, the analyzed synchronous data are judged according to a preset condition, if the synchronous data do not meet the preset condition, a fault exists in the control system, and fault prompt information is output to a user. The preset conditions at least comprise network load conditions and network communication conditions. Specifically, the network load condition is used to determine whether there is an overload operation condition in the control system, and the network connection condition is used to determine whether there is an open circuit condition in the control system. It is understood that the preset condition may also include other conditions, such as whether the device accessing the system has the related right, and the present embodiment is not limited thereto.
In one specific embodiment, the method includes the steps that data of all nodes in a control system are obtained, wherein the nodes comprise control equipment and two-layer nodes, the two-layer nodes comprise operation nodes and server nodes, and control system monitoring software can be run based on the two-layer nodes to monitor the control system and obtain the data of all the nodes; analyzing and processing the data of all the nodes to obtain diagnosis data; determining whether the control system has a fault or not according to the contents of system operation load, network on-off state and the like; and if the data of the node is not received, judging that the control system is in a suspected fault state.
Optionally, a mechanism for analyzing and processing the synchronization data is set: acquiring synchronous data every 1s of time period; if the synchronous data are obtained, analyzing the synchronous data in real time; and if the synchronous data cannot be acquired, acquiring the synchronous data every 1 s.
The embodiment analyzes the synchronous data; and judging whether the analysis result meets preset conditions or not, if not, judging that a fault exists in the control system, and outputting fault prompt information, wherein the preset conditions at least comprise network load conditions and network communication conditions. The synchronous data is judged according to the preset conditions, whether faults exist in the control system is further identified, accordingly, potential safety hazards in the control system are found in time, and stability and safety of the control system are improved.
In another embodiment, the obtaining real-time diagnostic data further comprises:
and if the real-time diagnosis data is failed to be acquired, judging that a fault exists in the control system, and outputting fault prompt information.
For example, after the step of obtaining the real-time diagnostic data is performed, if the real-time diagnostic data is not successfully obtained, it indicates that a fault exists in the control system, so that the real-time diagnostic data cannot be obtained, and at this time, it is directly determined that the fault exists in the control system, and fault prompt information is output to a user.
Specifically, the diagnosis state of the control network is determined according to whether a network message of real-time diagnosis data is received: if the real-time network message of the control system can be received, judging that the control system is in a normal operation state; and if the real-time network message of the control system cannot be received, judging that a fault exists in the control system.
If the real-time diagnosis data fails to be acquired, the fault in the control system is judged, and fault prompt information is output. When the real-time diagnosis data is not received, the fault in the control system is directly judged, so that the potential safety hazard in the control system is timely found and processed, and the safety of the control system is improved.
In another embodiment, determining that a fault exists in the control system further comprises:
step 1: acquiring historical fault data, and acquiring the duration of the fault based on the historical fault data;
step 2: judging whether the duration time of the fault exceeds preset time or not;
and step 3: and if the preset time is exceeded, judging that the control system is in a serious fault state, and outputting a serious fault prompt message.
Illustratively, upon detecting a fault in the control system, historical fault data is obtained. Wherein the historical fault data is diagnostic data in a historical time period in which a fault exists. Based on the historical fault data, a continuous historical time period is determined that includes the current time period, and thus the duration. For example, 10 historical time periods are included before the current time period, and the historical time period 1 to the historical time period 10 and the current time period are respectively set according to the time sequence. If the fault exists in the historical time period 2-the current time period, the duration is the historical time period 2-the current time period; if the fault exists in the historical time period 1-the historical time period 5, the historical time period 7-the current time period, and the fault does not exist in the historical time period 6, the duration is the historical time period 7-the current time period.
Illustratively, determining whether the duration of the fault exceeds a preset time; and if the duration time of the fault exceeds the preset time, judging that the control system is in a serious fault state, and outputting fault prompt information to a user. The serious fault state refers to the situation that a persistent fault exists in the control system, the severity of potential safety hazards of the control system is higher than that of general faults or temporary faults, and in most cases, the control system cannot automatically remove the serious fault state and needs manual intervention.
Specifically, whether the fault duration time of the control system reaches the filtering time is judged, if yes, the fact that the control system actually triggers the fault is indicated, and if the state of the actual triggering fault has a corresponding reminding module, reminding information is pushed to a user. The filtering time is used for shielding short-term or intermittent faults and avoiding the fault judgment in the control system.
In one specific embodiment, data is acquired through a controller and a diagnostic data collection program running on a layer two node, wherein the diagnostic data collection program is deployed on the layer two node and is used for acquiring the running state of an operating node where monitoring software is located and periodically sending the running state; receiving and processing data acquired by a controller and a diagnostic data collection program through a diagnostic service program to obtain real-time diagnostic data, wherein the diagnostic service program is deployed in all two-layer nodes, and all data of the controller and the two-layer nodes are collected and summarized to obtain the real-time diagnostic data; analyzing the real-time diagnosis data through a related program to obtain a real-time diagnosis state of the control system; and determining a fault prompt state based on the real-time diagnosis state, if fault prompt needs to be carried out on the user, pushing prompt information to a prompt module through a diagnosis service program, and displaying the prompt information to the outside through the prompt module.
The embodiment acquires historical fault data and acquires the fault duration based on the historical fault data; judging whether the duration time of the fault exceeds preset time or not; and if the preset time is exceeded, judging that the control system is in a serious fault state, and outputting a serious fault prompt message. Whether the duration time of the fault exceeds the preset time is judged to avoid intermittent fault occurrence, or under the condition that the control system automatically repairs the fault in time after the fault occurs, prompt information for prompting errors is pushed to a user, and finally the fault judgment is avoided.
