Examples

The embodiment provides a ONCALL redundancy system, which is applied to hydropower station monitoring management, as shown in fig. 1, and the ONCALL redundancy system includes: the system comprises a management area switch, ONCALL system switches and a plurality of ONCALL servers for constructing a local area network, wherein one of the servers is a main ONCALL server, and the rest of the servers are standby ONCALL servers; a plurality of short message sending modules for sending alarm information; the management area switch and the ONCALL system switch realize communication through a main ONCALL server; the plurality ONCALL of server stations ONCALL servers are respectively connected with a management area switch and a ONCALL system switch; the short message sending modules are respectively connected with the ONCALL system switch.

For example, in this embodiment, the ONCALL redundant systems adopt 2 ONCALL servers, 1 system switch, and each ONCALL server needs to provide 2 network cards, where one network card is connected to the management area switch through a network cable, and the other network card is connected to the ONCALL system switch through a network cable. At the same time, there are at least 2 short message sending devices of different communication channels: a short message and voice sending device (such as a short message cat) and a mobile short message platform. The server on the hardware needs redundancy, and the short message cat and the mobile short message platform are mutually redundant.

Specifically, the software adopts a containerization technology, namely, the service application of the server is packaged into a container, so that the independence and portability of the service are ensured. ONCALL server builds a plurality of containers, any ONCALL server comprising: the system comprises an application unit, a cache unit, a database unit and a state monitoring unit; the data flow between the two ONCALL servers can be shown with reference to fig. 2, and the state monitoring unit and the application unit are respectively connected with the database unit (the connection diagram of the database unit and the application unit is not shown); any cache unit is connected with all application units; any one state monitoring unit is connected with all the cache units, namely, two ONCALL servers share data in the cache. Specifically, the application unit comprises a UI module, a site management module, a communication service module, an analysis service module, a sending service module and a receiving service module. The state monitoring unit is responsible for monitoring the states of other modules or units, and if any program (including each module and database unit in the application unit) of one ONCALL server is abnormal or the communication of the data source is overtime, the program is switched to the normal ONCALL server.

Illustratively, the determination rules of the master ONCALL server are as follows:

A1, a ONCALL server which is started by default and preferentially is a main ONCALL server, and the rest ONCALL servers are standby ONCALL servers;

a2, monitoring whether the main ONCALL server and the standby ONCALL server are abnormal in real time;

a3, if the current main ONCALL server is abnormal, selecting one of the normal standby ONCALL servers as a new main ONCALL server, and reducing the original main ONCALL server to the standby ONCALL server.

Wherein, the unusual situation that ONCALL server mainly exists includes: an application unit exception, a database unit exception, or a data source communication timeout.

1) Monitoring whether the application unit is abnormal, comprising:

And the state monitoring unit is used for reading the operation data of each application module (the UI module, the site management module, the communication service module, the analysis service module, the sending service module and the receiving service module) from the cache unit, judging whether the operation state of each application module is abnormal or not according to the operation data, and judging that the application unit is abnormal if any application module is abnormal.

2) Monitoring whether the database unit is abnormal, comprising:

And reading connection state data of each application module (the UI module, the site management module, the communication service module, the analysis service module, the sending service module and the receiving service module) and the database unit from the cache unit by using the state monitoring unit, judging whether the connection state of each application module and the database unit is abnormal or not according to the connection state data, and judging that the database unit is abnormal if the connection state of all the application modules and the database unit is abnormal.

3) Monitoring whether data source communication is overtime, comprising:

And reading the state data of the receiving service module from the buffer unit by using the state monitoring unit, judging whether the receiving service module does not receive the heartbeat within the preset time according to the state data of the receiving service module, and if so, judging that the communication of the monitoring data source is overtime.

Specifically, before ONCALL redundant systems operate, the configuration file needs to be filled with the local IP and the remote IP.

When ONCALL redundant systems are started, the state monitoring unit writes the local IP as a main use into the local and remote caches. The first started server is the main ONCALL server, and the later started server finds that the cache has data and will not write into the cache unit. All ONCALL servers regularly read the IP of the main ONCALL server in the cache unit, compare with the local IP in the configuration file, consider itself as the main if the IP is consistent, and consider itself as the standby if the IP is inconsistent. And the ONCALL server which is considered to be the main server normally operates, and the standby server waits to operate. The UI module, the site management module, the communication service module, the analysis service module, the sending service module and the receiving service module periodically write the running state of the program into the local cache unit and the remote cache unit, and the state monitoring unit judges whether to change the main IP in the cache by periodically reading the state of a local ONCALL server and the state of a remote ONCALL server in the local cache unit. The state monitoring unit is also connected with the database unit periodically to judge whether to change the main IP in the cache.

In order to maintain redundant data consistency, the database unit and the cache unit also make corresponding synchronization mechanisms: the database units are arranged in a double-master mode and are mutually master and slave, the database units are changed, and data can be automatically synchronized into the database units of the other set of servers. Data with higher real-time performance or high-frequency program access is synchronously written into the cache of the 2-stage ONCALL server.
