Description
Technical field
The present invention relates to platform modeling methods in software communication architectural framework, and in particular to one kind is based on software communication system
The multi-layer platform modeling method of structure.
Background technique
Software communications architecture SCA (Software Communication Architecture) is U.S. army's joint war
Art radio system JTRS (Joint Tactical Radio System), which develops software, can configure the primary demand of radio station
And the software radio architecture independently of concrete application established.The target to be realized of SCA is: greatly providing and is deployed in
The operating flexibility and interoperability of the communication system of global range, system upgrade is simple, reduces system development and operation
Management cost.
According to the definition of SCA standard, all devices in system are all abstracted as a logic in SCA software platform and set
It is standby.Logical device is ageng of the specific physical equipment on SCA platform, using the equipment interface of SCA standard by bottom thousand
Poor ten thousand other physical device interface standardization.To realize the separation of system soft and hardware.However, the software complicated for one
Radio system, resource extent is big, and system architecture is complicated, and system administration realizes that difficulty is big.It is set based on traditional single logic
Standby abstract mechanism, it is difficult to realize the management to such extensive resource.Specific drawback is as follows:
Abstract depth is inadequate: being only abstracted to equipment, the tension management person of system faces such bottom, huge equipment
Object, it is difficult to realize the service logic of efficient management and complexity.
Lack efficient platform management and communication mechanism: in system operation, platform there are a large amount of data interaction,
Such as power-on self-test, period self-test, parameter configuration；Ununified, efficient communication constraint, causes system design difficulty big.
Platform modeling lacks standard criterion constraint: there is no the constraint to platform modeling in SCA, causing platform modeling efficiency
Low and incompatible, the portability of software is also poor.
Summary of the invention
The present invention provides a kind of multi-layer platform modeling method based on software communications architecture, existing to solve

It is standby, for creation logical device port and SPD.xm, SCD.xml, PRF.xml, DPD.xml configuration file；
Step 3: implementing the modeling of the node layer, according to the function side of the architecture design of system and each equipment of system
System resource is divided into several subregions with standalone feature boundary, i.e. node by boundary, is set for the creation of each node is corresponding
Standby manager and equipment manager port, and DCD.xml configuration file is created for equipment manager；
Step 4: implementing the podium level modeling, according to existing nodal information, create domain manager and the management of creation domain
Device port, and PCD.xml configuration file is created for podium level.
The principle of the invention: system platform is abstracted as three levels: mechanical floor, node layer and podium level by the present invention.Equipment
The object of layer is logical device, and logical device is ageng of the system processor part in system platform, using SCA standard
Equipment interface；The object of node layer is equipment manager, and node is an abstract concept, is the institute managed the node
The subregion for having equipment to constitute is abstracted, while being also the administrative unit of the subregion；Podium level is the highest level of abstraction of system domain, is
System platform is abstracted, managed object is all nodes of system, itself object is domain manager.
More preferably to realize the present invention, may further be: the device object be in real system physical device on platform
Ageng, with object device correspond；The standard device that the logical device is inherited in software communications architecture connects
Mouthful, the difference of bottom hardware interface is shielded for upper platform.
Optional: the resource in each node is managed by an equipment manager, including described is patrolled
Collect the technical characteristics such as registration, cancellation, inquiry and the configuration of equipment；The equipment manager is according to the DCD.xml file acquisition
The essential information technical characteristic of equipment.
Optional: the domain manager is responsible for the registration and cancellation of the node.
Optional: the domain manager has a Control Cooling user port and a data type supplier end
Mouthful；The equipment manager has a Control Cooling supplier and a Control Cooling user port, while having one
Data type supplier and a data type user port；The logical device has a Control Cooling supplier port
With a data type user port.
Optionally, the podium level control command issues process specific step is as follows:
Step 11: the control information that podium level receives upper layer application or independently generated by platform is analyzed and is converted to control
Instruction is sent to the equipment manager Control Cooling supplier end by the Control Cooling user port of the domain manager
Mouthful；
Step 12: the equipment manager parses the control command received, in registered device object
Search issued target device object；If inquiring target device object, pass through the Control Cooling in equipment manager
User port is pushed to the Control Cooling supplier port of target device；
Step 13: the target device object parses the control command received, and is configured to mapped object
Device is managed, realizes the control to physical equipment.
Optionally, steps are as follows for the device object reported data:
Step 21: the logical device collects the data reported by corresponding physical device, and handles data, so
Afterwards again by the data type supplier port of data-pushing to corresponding device manager；
Step 22: the equipment manager is handled and is merged to received data, will treated data-pushing extremely
The data type supplier port of domain manager；
Step 23: the domain manager carries out information fusion and processing to the data reported by each node again, is reported to
Tension management application.
Beneficial effects of the present invention: of the invention that system platform is abstracted as by three layers based on software communications architecture
Secondary, i.e. mechanical floor, node layer and podium level are set all of system platform by the thought of this multilevel hierarchy, partition management
It is standby to be included in that a logical level is clear, in management framework of interface standard, it is realized for system in complicated system administration, such as dynamic
Reconstruct, health monitoring, troubleshooting etc. provide basis.
