It should be noted that, for a subsystem having both a physical machine architecture and a cloud architecture, its data source is different in the physical machine architecture and the cloud architecture. For a subsystem with only a physical machine architecture, whether switching to the physical machine architecture or the cloud architecture, the data source of the subsystem is only a front-end processor.
Fig. 2 is a schematic diagram of another integrated monitoring system according to an embodiment of the present application, as shown in fig. 2, including an ISCS real-time server, at least two operation workstations, an ISCS system switch, a front-end processor, a PA system, a CCTV system, a PIS system, a cloud platform egress switch, a virtual ISCS real-time server, a virtual interface server, a virtual CCTV platform server, and a virtual PIS publishing system server.
The PA subsystem comprises a PA system switch, a broadcast control host and the like; the CCTV system comprises a CCTV system exchanger, a CCTV platform server and the like; the PIS system includes a PIS system switch, a PIS distribution server, and the like.
The two operation workstations are respectively connected with an ISCS system switch, the ISCS system switch is connected with a front-end processor, the front-end processor is connected with a PA system switch, and the PA system switch is connected with a broadcast control host. The virtual ISCS real-time server is connected with the virtual PIS release server and the virtual CCTV platform server through the virtual interface server respectively. These are all fixed connections.
The connection between the devices of the integrated monitoring system in the physical rack configuration mode is shown in fig. 3, and the integrated monitoring system further includes, in addition to the above-mentioned fixed connection: the ISCS real-time server is connected with the ISCS system switch, the front end server is connected with the CCTV system switch, the CCTV system switch is connected with the CCTV platform server, the front end server is connected with the PIS system switch, and the PIS system switch is connected with the PIS release server.
The connection between the devices of the integrated monitoring system in the cloud architecture mode is shown in fig. 4, and the integrated monitoring system further includes, in addition to the above-mentioned fixed connection: the ISCS system switch is connected with the cloud platform outlet switch, the cloud platform outlet switch is connected with the CCTV system switch, and the cloud platform outlet switch is connected with the PIS system switch.
It should be noted that, the switching of the devices in the cloud architecture mode and the physical machine architecture mode may be performed manually, and the switching in software is automatic.
The operation workstation needs to support configuration of a plurality of data sources, establishes connection with all the data sources in parallel when the operation workstation is started, periodically detects connection states, records the connection states into a connection state table according to configuration sequences, sequentially searches available connection from front to back in the connection state table, and takes the first searched available connection as current connection for the operation workstation to acquire real-time data and send a connection channel of a control command. When a new available connection is detected in the connection state table and is located before the current connection in the connection state table, the current connection is automatically switched to the new available connection. When the current connection is interrupted, the available connection is searched in the connection state table, if the available connection exists, the current connection is switched to the available connection, and if the available connection does not exist, the current connection is maintained unchanged, and a new connection is waited for being established. Under normal conditions, the virtual ISCS real-time server of the cloud architecture is configured as a first data source, the ISCS real-time server of the physical machine architecture is configured as a second data source, so that the operation of the ISCS system of the cloud architecture is guaranteed to be prioritized, and the operation of the ISCS system of the physical machine architecture can be switched to when the cloud platform fails.
When switching to a cloud architecture, the virtual ISCS real-time server needs to be connected with an FEP of a front-end processor under the cloud to acquire PA system data, and is connected with a virtual interface server on the cloud to acquire CCTV system and PIS system data; when switching to a physical machine architecture, the ISCS real-time server is only connected with the front-end processor FEP to acquire data of the PA system, the CCTV system and the PIS system, and in order to realize multiplexing of the virtual ISCS real-time server on the cloud and the software connection module of the real-time server under the cloud, the connection module can realize automatic switching.
The connection module obtains the data of the PA system, the CCTV system and the PIS system from the virtual interface server or the front-end processor FEP, and depends on the connection states of the virtual interface server and the front-end processor FEP and the PA system is only connected with the front-end processor FEP, so that only the data sources of the CCTV system and the PIS system in the connection module are considered to be switched. The FEP and the virtual interface server of the head-end processor respectively diagnose the connection state with subsystems (CCTV system and PIS system) and externally provide a consistent external connection state acquisition interface;
when the virtual ISCS real-time server and the connection module on the ISCS real-time server are started, connection is respectively established with the front-end processor FEP and the virtual interface server, and connection states of the front-end processor FEP and the virtual interface server are periodically detected and connection states of the front-end processor FEP and the virtual interface server and subsystems (CCTV system and PIS system) are obtained. When the cloud architecture is switched, the connection state of the virtual machine interface server is available, and the virtual interface server is available in connection with the CCTV system and the PIS system, and then the connection module CCTV system and the PIS system data source are set as the virtual interface server. Because the PA system is only connected with the front-end processor FEP, the virtual ISCS real-time server obtains PA system data from the cloud lower front-end processor FEP and obtains CCTV system and PIS system data from the cloud virtual interface server at the moment; when the connection state of the connection module and the virtual machine interface server is unavailable and the connection state of the front-end processor FEP is available and the connection of the front-end processor FEP and the CCTV system and the PIS system is available, the data source of the connection module CCTV system and the PIS system is set as the front-end processor FEP. At this time, the ISCS real-time server will obtain PA system, CCTV system, PIS system data from the cloud lower front end processor FEP.
In addition, separate switching of the cloud-up virtual CCTV system platform server and the cloud-down CCTV system platform server, the cloud-up virtual PIS system publishing server and the cloud-down PIS system publishing server can be realized, for example, when switching to a cloud architecture, if only the virtual CCTV platform server fails, the connection between the virtual interface server and the virtual CCTV platform server will not be available, at this time, the connection between the cloud-down CCTV platform server and the CCTV switch and the connection between the CCTV switch and the front-end processor FEP are turned on, the connection between the front-end processor FEP and the CCTV system platform server becomes available, at this time, the virtual ISCS real-time server will automatically acquire the data of the CCTV system from the front-end processor FEP, and other data streams remain unchanged.
