Description

Technical Field

[0001] This invention relates to the field of software-defined radio technology, and more specifically, to a multi-channel software-defined radio platform modeling method, apparatus, medium, and system. Background Technology

[0002] Existing software-defined radio systems adopt a scalable open architecture, constructing a modular, universal, and standardized hardware platform. Multiple application waveforms can be quickly deployed on the hardware platform, decoupling the physical platform from functional applications. This achieves the goals of hardware universality, software loadability, performance upgradeability, and functional scalability, fundamentally solving the problems of interconnection, interoperability, and interoperability between software-defined radio devices.

[0003] During the development of software-defined radio systems, hardware processing units are abstracted and encapsulated as device components, waveforms are encapsulated as several waveform components, and device components communicate with waveform components through external input / output ports. Platform software resources are encapsulated as services. In application scenarios where multiple waveforms are deployed simultaneously in a multi-channel radio system, when multiple waveform components need to access a device or service component at the same time, the current platform modeling and implementation have the following problems: 1) Some methods do not support multiple waveform components accessing a device component at the same time; 2) Some methods support multiple waveform components calling a device component at the same time, but the number of ports supported by the device component is fixed, waveform modeling and platform modeling are not decoupled, multi-channel waveforms require multiple sets of waveform models, and lack scalability. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a multi-channel software radio platform modeling method, device, medium and system that supports complete decoupling of waveform modeling and platform modeling, thereby reducing the workload of waveform modeling during waveform development.

[0005] The objective of this invention is achieved through the following solution:

[0006] A multi-channel software radio platform modeling method includes the following steps:

[0007] S1, Device Component Modeling: Define inherited device components, input / output ports, and device attributes;

[0008] S2, Device Component Encapsulation: Build container code and functional code, with the functional code nested within the container code, and compile the device component container code and functional code together to generate executable code;

[0009] S3, Waveform component communicates with device component: When multiple channels are deployed simultaneously, the waveform component is connected to the device component. The device component receives data from the first waveform component through a port and then sends the data to the second waveform component.

[0010] Furthermore, the device specifically includes a modem hardware abstraction layer device.

[0011] Furthermore, when the device is a modem hardware abstraction layer device, the inherited device component specifically inherits the interface of the basic device component; the port attributes of the input and output ports include name, data type, direction and number of connections, and only one pair of input ports and usage ports are provided externally, and the number of connections is configurable; the device attributes include device status attributes.

[0012] Further, in step S2, the construction of container code and functional code, with the functional code nested within the container code, and the compilation of the device component container code and functional code together to generate executable code, specifically includes the following sub-steps:

[0013] S21, Device Component Server-Side Framework Generation: Based on the device component model, use the IDL compiler to generate client stubs and server-side framework code;

[0014] S22, Container code implementation: Based on the client stub and server framework code, the device component container code is implemented by inheriting the interface of the basic device component. It manages input and output ports and adopts a two-level management method with embedded multiple connections for connection management, as detailed below:

[0015] S22.1, When using a port, iterate through the connection list.

[0016] S22.2, compare the connection port with the port name in use. If a matching port is found, execute S22.3; otherwise, execute S22.1.

[0017] S22.3, Check if the connection exists. If the connection exists, execute S22.4; otherwise, execute S22.1.

[0018] S22.4 After finding that the connection exists, narrow the object handle type and determine whether the narrowed object handle is valid. If the handle is valid, execute S22.5; otherwise, execute S22.1.

[0019] S22.5, Add to the connection queue connected to this port;

[0020] S23, Add functional code to the container code, which includes the following sub-steps:

[0021] S23.1, the waveform component sends data to other waveform components through the modem hardware abstraction layer device: in this process, the modem hardware abstraction layer device is the server and the waveform component is the client; utilizing the CORBA characteristics of the modem hardware abstraction layer device, the modem hardware abstraction layer device component acts as the server, supporting multiple clients to access the server simultaneously, the waveform component sends data to the modem hardware abstraction layer device through the provided port, the modem hardware abstraction layer device parses the target address, looks up the address mapping table, and calls the underlying driver to send data to other waveform components;

[0022] S23.2, the waveform component receives data from other waveform components through the modem hardware abstraction layer device: in this process, the waveform component is the server and the modem hardware abstraction layer device is the client; the modem hardware abstraction layer device component receives data from the bus, parses the target address information in the message packet header, queries the target address LD list subscribed to by the peer waveform component, and forwards the data to the subscribed waveform component by using the port according to the subscription relationship between the target address LD and the port connection;

[0023] S24, Executable implementation: Compile the device component container code and functional code together to generate executable code.

[0024] Further, in step S3, the device component receives data from the first waveform component through the port, and then sends the data to the second waveform component through the underlying driver, specifically including the following sub-steps:

[0025] Communication between waveform components and modem hardware abstraction layer device components: The modem hardware abstraction layer device component receives data from the bus, parses the destination address LD in the message packet header, queries the list of LDs subscribed to by the peer waveform component, and forwards the data to the subscribed component by using the port according to the subscription relationship between the destination address LD and the port connection.

[0026] A multi-channel software radio platform modeling apparatus includes a processor and a memory, wherein the memory stores a computer program that, when loaded by the processor, executes the method described in any of the preceding methods.

[0027] A computer-readable storage medium storing a computer program therein, the computer program being loaded by a processor and executing the method as described in any of the preceding claims.

[0028] A multi-channel software radio platform modeling system includes the multi-channel software radio platform modeling apparatus as described above.

[0029] The beneficial effects of this invention include:

[0030] (1) This invention can simplify waveform modeling and coding: The highly abstract platform model adopts a two-level management method with multiple connections embedded in the port. The device or service component only needs to retain a pair of transmit and receive ports to establish a connection and communication with multiple waveforms. In the case of complex waveform modeling, the number of multi-channel waveform modeling models is reduced by a factor of two. For example, for an 8-channel FM waveform, only one waveform model is needed, which can greatly reduce the workload of modeling and coding waveforms and device components.

[0031] (2) The present invention has high scalability and maintainability: the current implementation does not support the expansion of hardware platform resources. If the number of deployed channels increases, it is necessary to modify the waveform and platform model, reimplement the container code, port the functional code and compile and generate the device component executable file. The present invention only needs to modify the number of port connections in the device component domain description XML file. Attached Figure Description
