Description

Technical Field

[0001] The present invention belongs to the field of aerospace measurement and control communication systems, and in particular, relates to integrated baseband equipment software, an operation method and a system for aerospace measurement and control. Background Art

[0002] The integrated baseband equipment is a terminal device that organically integrates multiple functions such as remote control, telemetry, ranging, speed measurement, and data transmission in the aerospace measurement and control communication system. It is a key component of the satellite TT&C (Telemetry, Tracking and Command) mission. The integrated baseband equipment can complete the baseband processing of aerospace USB mode, spread spectrum mode, BPSK mode, and QPSK mode measurement and control signals, and the modulation and demodulation of telemetry, remote control, and data transmission signals. It not only includes conventional remote control command sending, telemetry data reception, and ranging functions, but also includes remote control command reception, telemetry signal simulation, channel simulation, and other functions.

[0003] At present, the software of integrated baseband equipment mostly adopts a measurement and control mode to build an independent software. That is to say, in the development of traditional measurement and control baseband software, a modulation and demodulation system is often built into a software to realize remote control, telemetry, speed and distance measurement, data transmission and other measurement and control business functions. Traditional software usually consists of 3 to 4 software to realize multi-mode remote control, telemetry, speed and distance measurement, data transmission and other measurement and control functions. The developer of each software often needs to build and implement common functional modules from scratch. Although it can meet the measurement and control business function requirements, there are the same functional modules between multiple software, resulting in duplication of work. This duplication of work wastes time and resources, lacks module reuse and sharing, and often if there is a problem with a functional module in a software, it is often necessary to check whether there is a problem with the same functional module in other software, which increases the difficulty of software maintenance and is not conducive to the scalability of the software.

[0004] The patent document "A distributed control method and device for aerospace measurement and control software" (CN112631756A) provides a distributed software coordination service that can expand cluster processing capabilities through simple function calls. Although software clustering is achieved, multiple aerospace measurement and control software are still used, resulting in duplication of work.

[0005] Although the patent document "Aerospace Measurement and Control Integrated Test Software Framework System and Operation Method" (CN202210782266) realizes multi-mode measurement and control functions through network communication protocols, it uses UDP network classes and TCP network classes for implementation, which is easily constrained by the communication rate and transmission delay of TCP and UDP network communications, and will affect measurement and control services with high uplink and downlink rates or high real-time requirements. In addition, a protocol parsing module is added, which increases the complexity of the system.

[0006] The present invention adopts a reusable functional module construction idea and an abstract factory design pattern to achieve multi-mode measurement and control with one set of software, thereby reducing duplication of work and improving software maintainability and scalability.

[0112] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0113] by Figure 1For example, the integrated baseband equipment software is generally responsible for completing the following tasks: real-time monitoring of the equipment's operating status, and automatic alarming of fault information; setting the equipment's operating parameters to make it work in USB mode / spread spectrum mode / BPSK mode / QPSK mode; real-time monitoring of the equipment's operating parameters; the software receives downlink demodulated telemetry data, and performs original code quick view, data storage and data forwarding on the received data, with real-time and post-error rate statistics, error frame statistics and frame loss statistics functions; the software has a telemetry simulation source function, which can realize telemetry self-closed loop testing; the software has the ability to generate and send remote control commands, and has a small loop comparison function; it has data solution, data storage and real-time forwarding functions; it has macro storage, saving and modification functions. In addition, the software also has functions such as automated testing, capture, and remote monitoring; the software also has functions such as telemetry data display, spectrum display and status display; data interaction is realized through the TCP / IP protocol.

[0114] The present invention divides relatively independent functional modules in the system through common analysis of software requirements, explores common requirements in the modules, and adopts a reusable functional module design approach; it clarifies how to multiplex common requirements under different modulation and demodulation systems, and then designs corresponding functional modules from various aspects, introducing a highly targeted abstract factory pattern during module design.

[0115] In order to achieve the above-mentioned purpose, the present invention provides a comprehensive baseband equipment software for aerospace measurement and control, including: a hardware board.

[0116] by Figure 5 For example, the software of the hardware board is divided according to reusable functional modules, including an initialization module, a functional interface driver module, a human-computer interaction module, a data processing module, a data forwarding module, and a data storage management module.

[0117] The initialization module mainly includes: system self-check, board initialization, macro file loading and system parameter loading.

[0118] System self-check: initialize program variables and display the main interface;

[0119] Board initialization: complete the hardware board initialization operation by calling the initialization interface of the functional interface driver module;

[0120] Macro file loading: call the macro file loaded when the program exited last time, and obtain the board working parameters and modulation and demodulation mode according to the information in the macro file, and complete the hardware board working parameter setting operation by calling the parameter setting interface of the function interface driver module;

[0121] System parameter loading: call the relevant parameters when the program exited last time.

[0122] The functional interface driver module adapts the upper-layer functional module in a unified interface form to complete hardware board initialization, modulation and demodulation parameter setting, state acquisition, data acquisition and data transmission. The abstract factory mode is introduced to perform secondary encapsulation processing on the USB mode, spread spectrum mode, BPSK mode and QPSK mode interfaces under different modulation and demodulation systems, hide the details of the underlying communication protocol, define a unified interface function, and only provide simplified interface functions to the upper layer, so that the software can more flexibly handle the initialization, parameter control, data transmission and data acquisition of hardware under different modulation and demodulation systems, and realize the modular management of multi-mode measurement and control software.

[0123] The functional interface driver module and the baseband card exchange data through the CPCI bus. The maximum communication rate of TCP and UDP networks is 100Mb / s or 1000Mb / s, and TCP network communication transmission has delays, UDP network communication is unreliable, data is easily lost, and the correct implementation of measurement and control services cannot be guaranteed. The CPCI bus rate can reach 5Gb / s, which meets the high-speed and high-real-time measurement and control services.

[0124] The Abstract Factory pattern provides an interface for creating a series of related or interdependent objects without specifying their concrete classes. Figure 2 For example, it defines an abstract factory, abstract products, and clients. The abstract factory declares the collection of abstract products created by the factory. Abstract products can produce different types of abstract product instances. The concrete factory inherits the abstract product. It is the implementation of the abstract factory and creates corresponding concrete products. The client directly operates on the abstract factory and abstract products. Figure 4 For example, the abstract class is an abstraction of business logic. The specific implementation of the business is completed through the implementation class of the abstract class. They are a commitment to the upper layer and are relatively unchanged. When the requirements change, you only need to inherit the abstract class to expand the new measurement and control mode. At the same time, since the abstract class has not changed, the upper-level code that depends on the interface does not need to be changed.
