Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
For avoiding among the prior art electric power supervisory equipment's monitoring data acquisition to interrupt, mainly there are two kinds of modes: one method is to provide a pure hardware backup of a plurality of power monitoring devices, but the backup method requires that the monitored power devices such as a UPS and the like are correspondingly provided with a plurality of serial ports to be respectively connected with the plurality of power monitoring devices, and because the hardware devices are not supported (the monitored power devices such as the UPS and the like are usually provided with only one serial port), the method has certain limitation and is not suitable for practical application; another method is application backup, that is, multiple identical applications are run on the same monitoring device, but this method is complex to deploy in a Linux environment, and even if the identical applications are run, parameters such as internal package names of the applications need to be set to be different, which results in that when the applications are run at a later stage, it is not beneficial to identify and manage the main program and the backup program, and especially when the types of the applications are many, a restart error is likely to be caused. In addition, when the backup application program is switched, the power monitoring equipment needs to be restarted, so that the time is long, and the switching efficiency is slow. Therefore, the problem that monitoring data collection is forced to be interrupted still cannot be effectively solved in the prior art.
In order to solve the problems in the prior art, embodiments of the present invention provide a monitoring data acquisition device, a monitoring data acquisition method, a terminal, and a storage medium. In order to make the objects, technical solutions and advantages of the present invention more apparent, the following description is made by way of specific embodiments with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of a monitoring data acquisition device according to an embodiment of the present invention, which is detailed as follows:
this monitoring data collection system 1 is applied to power monitoring equipment, and this device 1 includes: at least two virtual containers, and a controller 11 for monitoring the at least two virtual containers. At least two virtual containers are respectively provided with a preset application program for polling and collecting monitoring data of the power equipment, and each virtual container comprises a master container 12 and at least one slave container 13. In addition, the preset application program in the master container 12 is in a data collection state, and the preset application program in at least one slave container 13 is in a standby state.
Specifically, the controller 11 is configured to periodically acquire heartbeat information of the main container 12. If the heartbeat information of the main container 12 is not acquired within the preset time period, the main container 12 is cut off, one slave container is selected from at least one slave container 13 to serve as a new main container, and data collection is carried out by using a preset application program in the new main container.
In some embodiments, at least two Docker containers, i.e., the above-described at least two virtual containers, may be built on the same power monitoring device using Docker (application container engine) technology. The main container 12 is connected to a data interface of a serial port of the power monitoring device, and is used for collecting monitoring data.
It will be appreciated that within a container, the applications that serve the same data collection role are unique. In the prior art of application backup, a plurality of applications that perform the same data collection function are configured in a monitoring host.
In some embodiments, the controller 11 may determine whether the preset application program of the main container 12 belongs to a normal operation state by periodically acquiring the heartbeat information of the main container.
It should be noted that the normal operation state may include a data collection state and a standby state. For the main container 12, the normal operating state refers to a data collection state; the normal operating state refers to a standby state for the slave container 13. Because the main container 12 is connected to the data interface of the serial port of the power monitoring device, the preset application program of the main container 12 can perform data acquisition through the serial port of the power monitoring device. Thus, the preset application program of the main container 12 is in a data acquisition state during normal operation; however, the slave container 13 is not connected to the data interface of the serial port of the power monitoring device, so that the preset application program of the slave container 13 cannot perform data acquisition, and the normal running state of the preset application program of the slave container 13 is an idle running state, that is, a standby state.
Illustratively, the heartbeat mechanism may be preset in a preset application program of the main container 12, so that the preset application program of the main container 12 periodically sends heartbeat packets to the controller 11. The controller 11 acquires the heartbeat information of the main container by periodically receiving the heartbeat packet. If the controller 11 acquires the heartbeat information within a preset time length, determining that the preset application program of the main container 12 belongs to a normal operation state; the controller 11 determines that the preset application program of the main container 12 is abnormally operated if the heartbeat information of the main container 12 is not acquired within a preset time period.
It is understood that the preset time length corresponds to a transmission period of the heartbeat packet. For example, the preset application of the main container 12 sends a heartbeat packet every 3 seconds, and accordingly, the preset duration is also set to 3 seconds. The controller 11 determines that the preset application of the main container 12 is abnormally operated if the heartbeat information of the main container 12 is not acquired within 3 seconds.
Optionally, the controller 11 is further configured to cut off the main container when the heartbeat information of the main container is not acquired within the preset time period, and the specific processing may be as follows: if the heartbeat information of the main container is not obtained within the preset time period, the controller 11 cuts off the main container from a data interface of the serial port of the power monitoring equipment.
Specifically, if the heartbeat information of the current main container 12 is not obtained within the preset time period, the controller 11 determines that the preset application program of the current main container 12 runs abnormally. The controller 11 cuts off the current main container 12 from the data interface of the serial port of the power monitoring device, so as to facilitate the subsequent access of a new main container.
Optionally, the controller 11 is further configured to periodically obtain heartbeat information of at least one slave container 13.
Accordingly, when the controller 11 selects one slave container 13 from the at least one slave container 13 as a new master container, the specific processing is as follows:
the controller 11 selects any one of the slave containers 13 for which the heartbeat information is normal as a new master container.
Similarly, the heartbeat mechanism is also preset in at least one preset application of the slave container 13, so that the heartbeat packet is periodically sent to the controller 11 from the preset application of the slave container 13. The controller 11 acquires the heartbeat information of the slave container 13 by periodically receiving the heartbeat packet, thereby determining the running state of the preset application program of the slave container 13.
When the controller 11 determines that the preset application program of the master container 13 is abnormally operated, and cuts off the master container 13, the controller 11 selects any one of the slave containers in a normal operation state from at least one of the slave containers as a new master container.
Further, the controller 11 is further configured to connect the new main container to a data interface of the serial port of the power monitoring device, so that the preset application program of the new main container is converted from the standby state to a data collection state for data collection.
It should be noted that the preset application program of the slave container 13 is actually in the idle running state, i.e., the standby state described above. When the slave container 13 is connected to the data interface of the serial port of the monitoring device and determined as a new master container, the preset application program of the new master container directly performs data acquisition through the serial port of the power monitoring device and converts the data acquisition state into a data acquisition state, so that the problem of monitoring data acquisition interruption is avoided.
Through setting up main container 12 and at least one from container 13 for when the application appears unusually predetermineeing of main container 12, only through the data interface connection state who switches the power monitoring equipment serial ports, can realize predetermineeing the backup switching of application, improved switching efficiency greatly, avoided the problem that monitoring data acquisition interrupted. In addition, the same preset application programs are respectively preset in different containers, so that the same preset application programs are all in independent operation environments, the isolation between the programs is higher, and the program management and the program identification are facilitated.
Optionally, referring to fig. 2, the preset application program of the master container and the preset application program of the slave container share a database, and the database is used for storing the collected power equipment monitoring data.
In practical applications, the data collected by monitoring the power equipment may include various types, for example: voltage, current, temperature, etc. Different classes of data require different pre-set applications for acquisition. Therefore, the same container may contain a plurality of preset applications for acquiring data of different types, and accordingly, each preset application may also correspond to a plurality of acquisition points, and perform polling acquisition on the acquisition points according to a preset polling sequence. For convenience of management, different ID codes may be preset for each preset application, and corresponding serial numbers are preset for each acquisition point in the same preset application according to a preset polling sequence. In this regard, the electrical equipment monitoring data stored in the database correspondingly includes: the method comprises the steps of presetting an ID code of an application program, presetting the corresponding sequence number of each acquisition point in the application program and acquiring data corresponding to each acquisition point.
The monitoring data of the power equipment is stored by sharing one database, so that the situation that the whole historical collected data is lost due to hanging of the running preset application program can be effectively avoided, and the safety of data storage is improved. Meanwhile, the acquired data is correspondingly stored according to the ID code of the preset application program and the serial number of each acquisition point, so that subsequent data management and data query are facilitated.
Optionally, after determining the new main container, and before connecting the new main container to the data interface of the serial port of the power monitoring device, the controller 11 is further configured to:
and inquiring the latest acquisition point serial number corresponding to the acquired data in each preset application program in the database according to the ID code of the preset application program, determining a polling starting point of each preset application program of the new main container according to the next acquisition point serial number of the preset polling sequence, and controlling each preset application program of the new main container to continuously perform polling acquisition according to the determined polling starting point.
Before switching the data interface, the controller 11 queries in advance the latest acquisition point serial number in which the acquisition data is already stored in each preset application program in the database, and determines the acquisition point serial number next to the acquisition point serial number as the polling start point of each preset application program of the new main container.
And after the new main container is connected to the data interface of the serial port of the power monitoring equipment, each preset application program continuously acquires data according to the determined polling starting point.
The controller 11 determines the polling start point of each preset program in the new main container according to the latest acquisition point sequence number in each preset application program in the database, so that the problem of polling timeliness caused by too many acquisition points, namely the problem of data loss caused by incapability of timely polling the terminal acquisition point can be effectively avoided.
Optionally, before the controller 11 queries the latest acquisition point serial number corresponding to the acquired data in each preset application program in the database, the controller 11 is further configured to:
and determining the number of corresponding acquisition points in the preset application program according to the ID code of the preset application program, and when the number of the corresponding acquisition points in the preset application program is less than or equal to the preset value, directly taking the initial polling points in the preset polling sequence as the polling starting points of all the preset application programs of the new main container.
In essence, when the number of corresponding collection points in the preset application is smaller than or equal to the preset value, the time for completing one polling of the preset application is also greatly shortened. Therefore, the controller 11 can directly use the initial polling point of the preset polling sequence as the polling start point of the preset application of the new master container without querying the database.
The preset value can be set by the user according to the acquisition requirement, and the invention is not limited in this respect.
Illustratively, the main container contains 2 preset applications (whose ID codes are 001 and 002, respectively) for collecting voltage data and current data, wherein the preset application 001 corresponds to 5 voltage collection points, the preset application 002 corresponds to 20 current collection points, and the preset value is set to 10. After the controller 11 determines a new main container, the controller 11 only needs to query the preset application program 002 in the database that corresponds to the collected data as the 19 th current collecting point, and use the 20 th current collecting point as the polling starting point of the preset application program 002, and at the same time, determine the 1 st voltage collecting point as the polling starting point of the preset application program 001. After the new main container is connected to the data interface of the serial port of the power monitoring equipment, the preset application program 001 performs polling collection again from the 1 st voltage collection point, and the preset application program 002 continues to perform polling collection from the 20 th current collection point.
Optionally, after the switching is completed, the controller 11 is further configured to restart the master container 12, so that the preset application program of the master container 12 is recovered to be normal, and the master container 12 is determined as a new slave container; the preset application of the new slave container is in a standby state.
After the new master container performs data acquisition, the controller 11 restarts the previous abnormal master container, so that the preset application program of the master container is restored to a normal operation state. At this time, the main container is not connected with the data interface of the serial port of the monitoring device, and data acquisition cannot be performed, so that the preset application program of the main container is in a standby state, and the main container is determined as a new slave container, so that next switching is facilitated.
The embodiment of the invention discloses a monitoring data acquisition device, which comprises: at least two virtual containers, and a controller for monitoring the at least two virtual containers; preset application programs for polling and collecting monitoring data of the power equipment are configured in the at least two virtual containers, and the at least two virtual containers comprise a main container and at least one slave container; the preset application program in the master container is in a data acquisition state, and the preset application program in at least one slave container is in a standby state; wherein the controller is configured to: periodically acquiring heartbeat information of the main container; if the heartbeat information of the main container is not acquired within a preset time period, cutting off the main container, and selecting one slave container from at least one container as a new main container; the preset application program in the new main container is in a data acquisition state.
So, through set up main container and follow the container respectively on same electric power supervisory equipment, and main container and follow the container and be independent operational environment, mutual noninterference. Meanwhile, the configuration controller is used for monitoring and switching the master container and the slave container in real time, so that when the preset application program of the master container is abnormal, the preset application program of the slave container can be switched in time for data acquisition, and the problem that monitoring data acquisition is forced to be interrupted due to the abnormal application program is effectively avoided. Meanwhile, the application program switching is realized by switching the data interface of the serial port of the power monitoring equipment, so that the program switching stability is higher, the power monitoring equipment does not need to be restarted, and the switching efficiency is high. In addition, compared with the existing application program backup scheme, the scheme is more convenient to deploy in a Linux environment, and the same application program does not need to be operated in the same operation environment, so that the problems of complex program identification and disordered program management are solved.
Furthermore, after the new main container is determined, the controller queries the latest acquisition point sequence number corresponding to the acquired data in each preset application program in the database according to the ID code of the preset application program to determine the polling starting point of each preset application program of the new main container, thereby effectively avoiding the problem of polling timeliness.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by functions and internal logic of the process, and should not limit the implementation process of the embodiments of the present invention in any way.
The following are embodiments of the apparatus of the invention, reference being made to the corresponding method embodiments described above for details which are not described in detail therein.
Fig. 3 shows a flowchart of an implementation of the monitoring data acquisition method provided by the embodiment of the present invention, and for convenience of description, only the relevant parts related to the embodiment of the present invention are shown, which are detailed as follows:

The method comprises the following steps:

Step 302, if the heartbeat information of the main container is not received within the preset time length, the main container is cut off, one slave container is selected from at least one container to serve as a new main container, and data collection is carried out by using a preset application program in the new main container.
Optionally, in step 302, "if the heartbeat information of the main container is not obtained within the preset time period, the main container is cut off", and the specific processing may be as follows: and if the heartbeat information of the main container is not acquired within the preset time, cutting off the main container from a data interface of the serial port of the power monitoring equipment.
