In one embodiment, the primary server 100 and the first standby server 200 may be implemented as separate servers or as a server cluster of multiple servers. The primary database 300, the first standby database 400, and the second standby database 500 may be implemented with at least one database among a relational database, a key-value storage database, a column storage database, a document-oriented database, and the like. The dispatch monitoring module 600 may be implemented with a network communication monitoring tool (e.g., a TCP connection monitoring tool) integrated with a temperature monitoring module.
As shown in fig. 2, based on the power grid monitoring system illustrated in fig. 1, the method for realizing high availability of data processing service specifically includes the following steps:
in step S100, the main server 100 collects status signals of a switch controller (not shown) in a switch cabinet (not shown), converts the corresponding status signals into monitoring data, and uploads the monitoring data to at least one of the main database 300 and the first standby database 400 for storage.
In one embodiment, when the connection between the primary database 300 and the primary server 100 is normal, the monitoring data of the primary database 300 may be preferentially uploaded into the primary database 300, and when an abnormality occurs in the connection between the primary database 300 and the primary server 100, the primary server 100 may directly upload the database to the first backup database 400. It should be noted that the primary server 100 may also upload the monitoring data to the primary database 300 and the first standby database 400 synchronously.
Step S200, the main database 300 compares data with the first standby database 400 in real time, and if data is missing, the missing data is uploaded to the main database 300 having the missing data or the first standby database 400 having the missing data.
In one embodiment, the primary database 300 performs data comparison with the first standby database 400 in real time, and if it is determined that there is missing data in the first standby database 400, the primary database 300 uploads the corresponding missing data to the first standby database 400. Otherwise, the first standby database 400 uploads the corresponding missing data to the primary database 300, so that the data between the first standby database 400 and the primary database 300 are synchronized and consistent.
In step S300, the scheduling monitoring module 600 monitors the operation state of the main server 100, and when it is determined that the main server 100 is abnormal, the main server 100 is turned off, and the first standby server 200 is synchronously started to collect a state signal of a switch controller (not shown). And uploading the monitoring data converted from the corresponding status signals to at least one of the primary database 300 and the first standby database 400 for storage.
In step S400, the scheduling monitoring module 600 monitors the operation status of the primary database 300 and the first backup database 400, and when it is determined that any one of the primary database 300 and the first backup database 400 is abnormal, the second backup database 500 is started to collect all data in the primary database 300 or all data in the first backup database 400.
In step S500, the second backup database 500 compares data with the primary database 300 or the first backup database 400 in real time to determine that the data is missing.
In one embodiment, when the primary database 300 is abnormal, the second backup database 500 compares the data with the first backup database 400 in real time after collecting all the data in the primary database 300, and if it is determined that the first backup database 400 has missing data, the second backup database 500 uploads the corresponding missing data to the first backup database 400. On the contrary, if it is determined that the second backup database 500 has missing data, the first backup database 400 uploads the corresponding missing data to the second backup database 500, so that the data between the first backup database 400 and the second backup database 500 are kept synchronous and consistent.
In the embodiment, the operation states of the main server, the main database and the first standby database are monitored by the scheduling monitoring module, and when the abnormal operation state of any equipment is determined, the corresponding steps are executed, so that an emergency mechanism is quickly started, the monitoring data can be timely acquired, and the loss of the previously stored data is avoided.
In one embodiment, as shown in fig. 3, there is provided a grid monitoring system 30 having a plurality of detection points 31, the system comprising a main server 32, a switch controller 33, a plurality of switches 34 provided at the respective detection points 31, a main database 35, and a first backup database 36, wherein:
the switch controller 33 is connected to each switch 34, and is configured to obtain a switching signal of the switch 34 and generate a corresponding status signal according to the switching signal; the switching signal comprises at least one of a fault isolation signal, a rejection trip signal, a closing signal and an opening signal.
Specifically, the switch controller 33 is further configured to obtain an electrical parameter at each detection point 31, control the first switch disposed at the first detection point to perform trip isolation when it is determined that the electrical parameter at the corresponding first detection point does not satisfy a preset judgment condition, obtain a fault isolation signal of the first switch when it is determined that the first switch trips successfully, and obtain a trip rejection signal of the first switch when it is determined that the first switch trips unsuccessfully; the switch controller is further configured to control the corresponding second switch to perform a switching-on action or a switching-off action when the switching-on instruction or the switching-off instruction is received, obtain a switching-on signal of the second switch when it is determined that the switching-on action is successfully performed, and obtain a switching-off signal of the second switch when it is determined that the switching-off action is successfully performed.
In one embodiment, the switch controller obtains the electrical parameters at each detection point, wherein the electrical parameters may reflect the voltage value, the current value and the like generated at the detection point. In one embodiment, the determination condition may be: the current value generated at the detection point is lower than a preset current threshold value. For example, the switch controller determines that the current amount at the corresponding first detection point does not satisfy the preset judgment condition, that is, the generated current value is higher than the preset current threshold, and at this time, the switch controller controls the first switch arranged at the first detection point to perform trip isolation. Of course, in the current embodiment, the determination of the determination condition may also be performed based on a plurality of current values generated at the detection point within an obtained certain detection time range, and when the switch controller performs the trip isolation control, the switch controller performs the calculation of the current average value based on the plurality of current values, and when the calculated current average value is higher than the preset current threshold value, controls the corresponding first switch to perform the trip isolation.
A main server 32 for collecting the status signal transmitted via the switch controller 33 and converting the status signal into monitoring data; the monitoring data comprises at least one of fault isolation data, switch tripping rejection data, closing data and opening data.
Specifically, the main server 32 is further configured to, when it is determined that the first switch trips successfully, obtain identification information of the switch controller 33, and convert the obtained fault isolation signal into fault isolation data in combination with the identification information; the main server 32 is further configured to, when it is determined that the first switch fails to trip, obtain identification information of the switch controller, and convert the obtained trip rejection signal into switch trip rejection data in combination with the identification information; the main server 32 is further configured to, when it is determined that the closing action is successfully performed, obtain identification information of the switch controller, and convert the obtained closing signal into closing data in combination with the identification information; the main server 32 is further configured to obtain identification information of the switch controller when it is determined that the switching-off operation is successfully performed, and convert the obtained switching-off signal into switching-off data in combination with the identification information.
In one embodiment, when the main server determines that the first switch is tripped successfully, that is, the isolation is currently considered to be successful, the main server converts the fault isolation signal into fault isolation data based on the acquired identification information of the switch controller. Of course, in the current embodiment, the fault isolation data may be generated based on the identification information of the switch controller, or the fault isolation data may be converted based on the information such as the starting time point of the fault occurrence, the time point of the fault isolation successful execution, and the like, so that the relevant staff may quickly locate and overhaul the fault point based on the acquired fault isolation data to determine whether the currently acquired information is incorrect. For the conversion of the switch tripping rejection data, the closing data and the opening data, reference may be made to the above embodiments, and the examples in this application are not described in detail.
In the above embodiment, the monitoring data is converted based on the acquired identification information of the switch controller, so that related workers can perform rapid positioning and maintenance of fault points based on the acquired monitoring data, and the maintenance work efficiency of the workers is improved.
The primary server 32 is further configured to upload the monitoring data to at least one of the primary database 35 and the first backup database 36 to store the monitoring data.
Specifically, the master server 32 is further configured to determine an uploading sequence of the monitoring data based on the communication state of the master database 35; the upload order includes at least one of a first upload order to maintain the synchronous upload of the monitoring data to the primary database 35 and the first standby database 36 and a second upload order to upload the monitoring data to the primary database 35 when it is determined that the abnormal communication state does not exist in the primary database 35; the uploading sequence further includes a third uploading sequence of uploading the monitoring data to the first backup database 36 when it is determined that the abnormal communication state exists in the primary database 35; the primary server 32 is further configured to upload the monitoring data to at least one of the primary database 35 and the first backup database 36 based on the determined upload order to store the monitoring data.
In one embodiment, the master server may further determine whether an abnormal communication state exists in the master database based on a TCP connection state with the master database. For example, in one embodiment, the primary server may send a TCP data packet to the primary database and receive a TCP response packet correspondingly fed back from the primary database, and if the primary server does not receive the TCP response packet within a preset time range, it may determine that the communication connection between itself and the primary database is disconnected. At this moment, when the main server determines that the first standby database normally operates, the monitoring data can be uploaded to the first standby database through a preset transmission protocol, so that even if the main database is abnormal, the interruption of data storage and data comparison processes can not be caused, the data storage and comparison reliability is improved, and the data processing service of the power grid monitoring system is always kept in a high-availability state.
In an embodiment, the Transmission Protocol adopted by the switch controller may be at least one of a GOOSE (Generic Object organized Substation Event) Protocol, a TCP/IP (Transmission Control Protocol/Internet Protocol), and the like, which is not limited in this embodiment of the present invention.
In one embodiment, when an abnormality of the switch controller is found, such as a fault isolation signal and a switch bounce rejection signal, when the main server or the first standby server converts monitoring data, an alarm event is automatically generated and synchronously sent to a background worker to prompt the background worker that a fault point exists and equipment needs to be overhauled in time, so that the equipment overhauling efficiency is improved, and the automation degree is monitored.
In the embodiment, on one hand, the addition of the first standby database can improve the reliability of data storage and comparison, so that the data processing service of the power grid monitoring system is always kept in a high-availability state; on the other hand, the alarm event of the alarm event is generated based on the main server or the first standby server, so that the effect of timely warning can be achieved, and the equipment maintenance efficiency is improved.
The main server 32 is further configured to control the main database 35 and the first standby database 36 to compare the monitoring data stored in the main database with the monitoring data stored in the first standby database in real time.
Specifically, before the main server controls the data comparison between the main database and the first standby database, the operating states of the main database and the first standby database need to be determined. And when any database object in the main database and the first standby database is determined to have an abnormal operation state, starting the corresponding standby database, and replacing the corresponding database object by the standby database to store the monitoring data and compare the data.
In one embodiment, the primary server may transmit a test packet to the primary database and the first backup database to confirm a current communication connection state, and determine whether the communication connection between the primary server and the primary database or between the primary server and the first backup database is disconnected according to a time of receiving a response packet. For example, if the master server does not receive the response packet fed back from the master database within a predetermined time range, for example, 3s-5s, the communication connection between the master server and the master database may be considered to be disconnected. At this time, the primary server needs to start the first backup database to replace the primary database with the first backup database for subsequent monitoring data storage and data comparison. Of course, in the current embodiment, the communication connection state may also be confirmed by using methods such as temperature monitoring, which is not limited in the embodiment of the present application. It should be noted that, in the embodiment of the present application, the number of the alternative databases is not limited, so as to avoid interruption of corresponding working threads caused by simultaneous disconnection between the main database and the first standby database and the main server.
In the above embodiment, the main server confirms the communication connection status between the main server and the corresponding main database or the corresponding first standby database by sending the test data packet to the main database or the first standby database, or by using a temperature monitoring method, so as to effectively monitor the operating status of the main database and the first standby database, avoid losing important data information when any one of the databases is abnormal, and improve the reliability of data storage.
And the first standby database 36 is configured to, based on the data comparison result, upload the corresponding stored first target monitoring data to the primary database 32 when it is determined that there is the missing first target monitoring data in the primary database 35.
