Description

Technical Field

[0001] The present invention relates to the technical field of informatization processing, and particularly to a system and method for analyzing and fusing and modeling task scenarios of informatization equipment. Background Art

[0002] Informatization equipment is a remarkable symbol of equipment modernization in the information age. It takes information technology as the basic means, realizes the interconnection, intercommunication, and interoperability of weapon equipment as the basic approach, and takes improving the information fusion ability between equipment as the basic goal, pursuing the information processing ability of weapon equipment, and thus improving the attack power, protection power, and mobility of the equipment. Informatization equipment is a further development based on mechanized equipment, and one way to achieve it is to use advanced information technology to informatize the original mechanized equipment.

[0003] Informatization equipment is the material basis of informatization warfare and an important factor in winning informatization warfare. Along with the development of informatization equipment, a series of new military theories such as information superiority strategy, information deterrence strategy, network-centric warfare, beyond-visual-range warfare, and integrated joint warfare have emerged. Major military powers have successively established new types of troops such as digital troops, electronic warfare troops, cyber warfare troops, and joint warfare troops. Informatization equipment and new combat theories have led to a new military revolution and promoted the evolution of the war form from mechanized warfare to informatization warfare.

[0004] With the continuous improvement of the functions and performance of informatization equipment, the applicable scenarios of the equipment have become increasingly complex, which has brought great challenges to the task scenario analysis and modeling work. It is necessary to consider not only external environmental factors such as external targets, troop deployments, geographical environments, and meteorological environments, but also the impact of the network environment on the combat effectiveness of informatization equipment, and even the effects of the interactions between informatization equipment entities. A multi-modal collaborative task scenario analysis and modeling method is required to meet the needs of the research and testing of a new generation of informatization equipment.

[0005] The US Department of Defense defines task scenario analysis and modeling from a military application perspective as: combining (Association), correlating (Correlation), and combining (Combination) data and information from many information sources to obtain state estimation (State Estimation) and identity estimation (Identity Estimation) of targets, as well as timely evaluating (Situation Estimation) the battlefield situation and judging (Threat Estimation) the threat level of targets.

[0006] Task scenario analysis and modeling involve the organization, management, identification, selection, and connection of task scenarios. Since task scenario analysis and modeling are oriented towards multiple military fields and command levels, most researchers start from the actual fields and levels they face and select applicable technologies. The ideal result of task scenario analysis and modeling is to reflect the real battlefield situation, provide predictions of events and activities, and thus provide the best decision-making basis.

[0007] The existing research on task scenario analysis and modeling technologies mainly includes the following seven functional domains:

[0008] ① Situation analysis and identification technology: Giving the situation and its annotations and explanations is the main purpose of information fusion. Research needs to be carried out on the definition, quantitative description, consistency discrimination, difference analysis, situation deduction and association of the situation, etc.

[0009] ② Information fusion algorithms: The research on the technical principles in this area generally does not involve the usage background, so it is relatively easy to obtain research reference materials. Domestic research began to track in the late 1970s and has a relatively strong reserve.

[0010] ③ Information fusion modeling technologies and methods involving the use of sensors: The research on the technical principles of this technology usually involves the usage background, so it is very difficult to obtain research reference materials. Domestic research in this area started relatively late, and the basic principles need to be further studied, and there are few basic data materials to support the research work.

[0011] ④ System management and integrated design technology: There is a relatively large reserve of this technology and relatively rich engineering practice experience, but there is a lack of theoretical analysis of the system structure and formal design technology of system integration under theoretical guidance and other theoretical and quantitative analysis technologies for guiding engineering practice.

[0012] ⑤ System demonstration and verification technology: The demonstration and verification of some specialized algorithms are mainly limited to the analysis of algorithm technologies, lacking the demonstration and verification of principles or prototypes with engineering application backgrounds. There are significant differences between the engineering application background and the theoretical analysis background. In engineering applications, there are differences between the error models, parameter adjustment models and theoretical models of actual systems. In order to effectively verify the applicability of algorithms, comprehensive research on system demonstration and verification technology needs to be carried out.

[0013] ⑥ System anti-interference design and usage technology based on information fusion technology: Domestic research on the anti-interference problems of information fusion and the problems to be considered in design is only some theoretical discussions and is far from reaching the level of engineering applicability.

[0014] ⑦ Experiment and verification technology for information fusion application research: The experimental verification technology and management system related to application research have not been systematized, especially there are obvious shortcomings in performance evaluation.

[0015] Generally speaking, most of the current research results only include some of the above-mentioned functional domains, and the complexity and applicability of each functional domain vary with specific applications. Summary of the Invention

[0082] To facilitate the understanding of the above technical solutions, the following is an illustration in combination with the accompanying drawings of the specification and specific examples, as follows:

[0083] I. Analyze the task environment of information-based equipment

[0084] To model different task scenarios such as cross-domain and cross-service of information-based equipment, it is necessary to analyze the task scenarios and extract the environmental elements in the task scenarios, including the external situation environment, network environment impact, internal cross-link environment, etc. that the information-based equipment faces in the task. The external situation environment mainly includes external targets, force deployments, geographical environments, etc.; the network environment impact mainly analyzes the possible cyberattack impacts and electromagnetic effects; the internal cross-link environment mainly analyzes how the detection and perception devices and action control devices interacting with the system cross-link and interact, and the possible faults that may occur inside the software system.

[0085] (1) Method for analyzing the external situation environment

[0086] (1) Analysis of external targets

[0087] External targets are the internal driving force for our actions and the most important external situation environment information in the actual scenario. Analyzing external targets needs to solve three basic problems: target characteristics, target categories, and target locations. The analysis of external targets mainly conducts research on these three basic problems.

[0088] ① Target feature analysis: The main task is to convert external target observation information (such as scale, perspective, appearance, etc.) into a more effective target feature description.

[0089] ② Target type analysis: Using target features for processing to obtain category prediction results, which can be in the form of a scoring value indicating the confidence level of the current category. Target classification methods can be classified into two ideas: one is the target classification method based on the probability model, and the other is the target classification method based on the deterministic model.

[0090] ③ Target location analysis: The main task is to give important parameter information such as longitude, latitude, altitude / depth, direction, speed, etc. of the external target.

[0091] Implementing effective external target analysis faces many technical challenges. On the one hand, due to the diversity of external targets in terms of scale, perspective, appearance, etc. and the complex data characteristics in the task scenario, it is difficult to accurately represent target features. On the other hand, multiple external targets may not be compatible, and it may not be possible to reconnoiter and strike them simultaneously. Therefore, it is necessary to dynamically adjust the list of external targets according to the situation, which may require adding new targets, adjusting existing targets, or even abandoning the current target, etc., thus affecting our actions. In addition, when external targets involve team collaboration, the adjustment or abandonment of external targets needs to be implemented after the team members reach an agreement.

[0092] (2) Force deployment analysis

[0093] The enemy and our force deployments have a direct impact on the external situation environment. Under the conditions of information-based warfare, force deployments will mainly show the following characteristics:

[0094] ① The basic combat units show a trend of miniaturization and multi-functionality. The "one specialist, multi-capable" weapon system will become the basic combat unit of future tactical-level joint combat arms; and the synthesis of arms pays more attention to lower levels, such as the regiment and battalion levels. These troops can independently perform a variety of combat tasks in terms of combat capabilities.

[0095] ② The characteristics of the tactical-level joint combat force grouping being multi-element integrated are becoming more obvious. This multi-element integrated grouping is transitioning from the multi-arm synthesis grouping within a specific service to the cross-service mixed grouping. The new type of hybrid integrated force envisioned by the US military has initially demonstrated the trend of the development of combat forces towards cross-service integrated grouping.

[0096] ③ The military establishment is developing towards a modular trend. Each service usually establishes as few fixed establishments as possible, and divides various arms troops into several "modules" according to certain specifications and weapon equipment characteristics. When in use, they can be selected according to the task needs and combined into different types of combat units.

[0097] ④ The command and control structure of the military tends to be "flattened", that is, reducing the command levels vertically, shortening the process of command information, and improving the response speed; interconnecting various combat forces horizontally to achieve information sharing. This "flattened" organizational method can not only enable grass-roots commanders to obtain necessary battlefield information and implement decentralized command, but also help senior commanders to quickly respond to the battlefield situation and implement centralized command.

[0098] (3) Geographical environment analysis

[0099] Geographical environment analysis aims to study the impact of the battlefield geographical environment on military operations, focusing on the overall application characteristics (including characteristics such as mobility, observation, shooting, concealment, camouflage, protection, communication, and engineering construction) demonstrated by the combination of geographical elements (including terrain environment, hydrological environment, etc.) on the mission. Geographical environment analysis should support the direct or appropriately processed rapid extraction of required information, be able to combine with combat missions, quickly obtain terrain units and their attributes, and support the analysis of the interrelationships between terrain units.

[0100] The analysis of the battlefield geographical environment is represented by terrain analysis, and common methods include the elevation method and the classification method. The elevation method determines the terrain based on the elevation of grid points in the battlefield area; the classification method divides the terrain into several categories according to the impact of different terrains on the mission (such as flat land, mountains, cities, etc.), then divides the battlefield into several regions according to the terrain characteristics, and clarifies the terrain type for each region to consider the impact of the terrain on the implementation of mission operations. Common battlefield division methods include the grid method, the irregular polygon method, and the random rectangle method.

[0101] Currently, the results of geographical environment analysis are mainly used to depict and describe the individual characteristics of geographical entities and their complex relationships in terms of time, space, and thematic attributes through military topographic map data, so as to objectively and effectively describe the characteristics of specific elements and entities such as landforms, water systems, vegetation, soil quality, transportation, and populated areas.

[0102] (4) Meteorological environment analysis

[0103] Currently, significant progress has been made in the research on analysis methods of the meteorological environment in the fields of weapon effectiveness analysis, combat risk analysis, meteorological threat analysis, etc. The evaluation research on the impact of the meteorological and oceanic environment on the exertion of weapon effectiveness has gradually developed from the analysis of the effectiveness of a single weapon under the influence of the environment to the overall combat effectiveness analysis of a combination of multiple weapons. The main analysis methods include: expert evaluation method, analytical method, simulation experiment method, etc.

[0104] The Earth's surface is divided into grid points. By sampling and quantifying continuous physical quantities that reflect the thermodynamic and kinetic properties of the environment and distributing them on the spatial grid points of four-dimensional space-time (longitude, latitude, altitude, and time), grid data is formed to characterize and study the local and global environmental conditions. Environmental grid data is the main form of data storage, transmission, and application in meteorological environment analysis and has obvious field structure characteristics. These environmental grid data continuously distributed in space-time constitute the field model of the meteorological environment. This field model of the meteorological environment changes dynamically over time and follows certain physical distribution and change laws, which is a relatively accurate simulation of the environment. By analyzing station observation data, historical environmental data, numerical simulation data, etc., a dynamic and realistic meteorological environment model can be constructed. However, the amount of data in this meteorological environment data model is huge, which will occupy more computing resources and storage resources. The explosively growing grid data brings huge pressure to the storage and transmission of the model.

[0105] In order to standardize the representation and exchange of meteorological environment data and construct different meteorological environment models, the complex meteorological environment can be segmented into different environmental element objects to obtain historical data of environmental elements and environmental statistical characteristic data, and then represented by different environmental element grid data. This is conducive to the organization and management of meteorological environment data and can improve the efficiency of meteorological environment analysis data and the reusability of meteorological environment analysis results to a certain extent.

[0106] (2) Analysis methods for the impact of network environment

[0107] Cyberspace is a multi-dimensional, cross-domain, and large-scale space. Cyberspace operations have the characteristics of a complex system. It is not only the accumulation of one or several network attack and defense means in terms of quantity, but also a large-scale system confrontation covering tactics and combat methods such as reconnaissance, control, attack, defense, deception, and deterrence. Therefore, the analysis of the impact of the network environment must be carried out around the characteristics of network confrontation.

[0108] Network confrontation is an activity that takes various means to destroy, damage, and paralyze the other party's network system, prevent the other party from obtaining, transmitting, and processing effective information, and at the same time implement overall protection for its own computer network to ensure the smooth flow of its own network information, including network attack, network defense, and detection. The basic characteristics of network confrontation are to conduct information network offense and defense with the computer network space as the battlefield, computers as the main weapons, information and software as the combat means, and computer network systems as the main targets. Network confrontation includes two categories: offensive network confrontation activities and defensive network confrontation activities.

[0109] (1) Impact analysis of offensive network confrontation activities

[0110] Upon analysis, it is found that network attacks vary in duration, with diverse methods and means, and different effects, presenting a complex and intricate situation. If the process of a network attack is summarized into several stages in chronological order, it can be divided into stages such as hiding the attacker's identity and location, collecting information about the target system, mining and analyzing vulnerability information, obtaining target usage permissions, concealing attack behavior, implementing the attack, opening backdoors, and clearing attack traces. Attackers use different methods and tools in each stage to achieve different goals, and these stages echo each other to jointly achieve the attack on the ultimate goal.

[0111] Any attack contains five basic factors: the attacker, tools, access, consequences, and target, and each factor contains several sub-factors. For example, the access factor contains sub-factors of three tactical stages: attack preparation, attack implementation, and trace clearing. A network attack can be regarded as a complex process in which many factors act together. This classification method clearly distinguishes the source, target, as well as consequences and means, which helps to describe the network attack model.

[0112] (2) Impact analysis of defensive network countermeasure activities

[0113] Network defense is to strengthen the detection, management, monitoring, and handling capabilities of its own vulnerabilities and status while enhancing the protection ability, so as to form a rapid response to security incidents. The purpose of network defense is to prevent or delay intrusion events, provide a longer reaction cycle for detecting and responding to network attacks, and combine with the formulated security policies and security plans to make protection, detection, and response constitute a network defense system.

[0114] Network attacks can cause consequences such as denial of service, information leakage, and information damage to the network and computer hosts. Usually, two metrics, namely network communication metrics and computable metrics of the host, are used as the basis for judging whether a network attack has occurred. Network communication metrics refer to network bandwidth, the number of TCP connections, packet loss rate, port usage information, and other measurable communication metrics. The computable metrics of the host mainly refer to the usage rate of computing resources of the host (mainly the usage of the CPU), the usage rate of storage resources (including the usage of memory and hard disk resources), and the open service information, etc.

[0115] In the network countermeasure system, attackers can use a variety of attack tools to carry out network attacks against different targets and purposes. An effective defense strategy must be able to quickly detect and judge network attacks and make accurate defense responses. Different from the traditional combat mode, network countermeasures mainly have the following characteristics:

[0116] (1) Multi-dimensionality

[0117] Network confrontation usually has unconventional spatio-temporal attributes. In the time dimension, from the issuance of instructions to the execution of tasks in network confrontation, it can be completed instantaneously. In the space dimension, network confrontation can be carried out in any region with information infrastructure globally, without the concepts of "front line" and "rear area" in traditional warfare.

[0118] (2) Cross-domain nature

[0119] Network confrontation often accompanies joint operations of multiple services. Modern warfare is a system confrontation integrating land, sea, air, space, and cyber. As an important part of it, cyber warfare is interconnected with other aspects. For example, the hard damage of information infrastructure by weapons such as missiles will rapidly reduce the cyber attack and defense capabilities; through cyber attacks, it is also possible to damage information systems-intensive areas or equipment such as airports and warships, reducing or even disabling their combat capabilities.

[0120] (3) Concurrency

[0121] Network confrontation is not one-way. Instead, both the enemy and ourselves have attacks and defenses at the same time. The information infrastructures of both warring sides are damaged to some extent during the confrontation, and their battle damage situations will directly affect the attack effectiveness in the next period. How to maximize the combat effectiveness of information infrastructure under the condition of being attacked and damaged is the main goal of network confrontation tasks. Which side can seize the opportunity, possess higher attack and defense means, and have stronger infrastructure repair capabilities will affect the result of network confrontation.

[0122] (4) Integration

[0123] Network confrontation is not "pure military". It requires the integration of military and civilian forces to jointly execute tasks. Different from traditional warfare mainly carried out by the military and weapons and equipment mainly controlled by the military, the country's major information infrastructure and attack and defense capabilities are mainly in the civilian sector. Once large-scale network confrontation breaks out, the military and civilians will jointly execute tasks. The integration and scheduling level of network confrontation forces is a direct manifestation of the cyber space combat capabilities.

[0124] (III) Analysis method for internal cross-linking environment

[0125] The internal cross-linking environment refers to the effect of the interaction between multiple equipment entities. In a war system, the actions between each entity will ultimately be transformed into the exchange of matter, energy, and information, thus resulting in mutual interaction. Accordingly, the internal cross-linking of the mission scenario can be divided into two major types: physical cross-linking and information cross-linking. Generally, the model's processing method for cross-linking is similar, that is: First, the active entity issues a cross-link; Second, the passive entity receives a cross-link; Third, both sides calculate the result according to the completion situation of the cross-link.

[0126] (1) Physical cross-linking

[0127] The description of the physical cross - link environment mainly includes cross - link name, initiator, recipient, cross - link content, cross - link parameters, etc. The content and parameters of the cross - link need to be determined according to the actual situation. For example, the content of the "attack - type" cross - link can be determined according to the need to judge the attack effect, and the parameters include entity effectiveness, combat conditions, engagement methods, etc.; the content of the "supply - type" cross - link includes the types and quantities of materials.

[0128] (2) Information cross - link

[0129] Information cross - link mainly includes three types: command, request, and report. Their contents can all be defined in a certain communication protocol format, which is equivalent to clarifying the syntax format of information cross - link, thus providing a syntax basis for information processing.

[0130] II. Analysis Technology of Information - based Equipment Task Rules

[0131] Many mission scenarios can be analyzed and described using rule - based methods. Especially at the tactical combat level, many tactics and doctrines can be represented by rules, enabling combat forces to act more autonomously. At the same time, considering the sharing of battlefield situation under information - based conditions, combat operations can be carried out in a self - synchronized manner.

[0132] Using rules to represent mission scenarios mainly consists of two parts: the first part is the condition, that is, the premise; the second part is the result, that is, the action to be taken. If the premise matches the known facts, then the result of the rule is executed. Generally, it can be expressed as: if P then C, where P refers to the premise of the rule and C refers to the conclusion that can be obtained or the operation that can be executed under the condition that P holds.

[0133] Suppose there is such a rule in an air combat: If our aircraft is locked by an enemy missile, then implement electronic jamming. This rule involves missile - type entities and the "locking" relationship between the aircraft and the missile. The jamming plan of the aircraft is determined according to the guidance method of the missile. Here, it is generally represented as a "jamming" plan, and its representation is as Figure 1 shown.

[0134] III. Analyze the Task Process of Information - based Equipment

[0135] The task process refers to the sequence of actions executed to achieve a certain combat objective. Due to the complexity of actual combat, it is impossible to describe all action processes one by one. Usually, according to actual needs, basic entity action models are established, and then corresponding action processes are combined according to task requirements. The description of a process generally should include the following contents: First, the basic description of the process, trigger conditions, execution necessary conditions, end conditions, suspension conditions, etc.; Second, determine the actions that make up this process, the execution entities of the actions, target entities, etc.; Third, the clear flow of each action execution. The representation of the process only needs to be described to an abstract level that can meet actual needs. For example, weapon shooting is essentially a process (target acquisition, aiming, firing), but for high-level tactical or campaign-level task analysis, if the resolution is low and the granularity is coarse, these details can be ignored.

[0136] The definition of a process mainly includes three categories of information: One is the descriptive information and control information of the process, including basic description, trigger conditions, context conditions, and exit conditions, etc.; The second is the activity definition related to the process, including atomic activities and composite activities; The third is the transition conditions between activities, which define the timing relationship of activity execution. For example, Figure 2 describes a certain "maneuver - engagement" task process, and its standardized representation is as Figure 3 shown.

[0137] IV. Information-based Equipment Scenario Fusion Modeling

[0138] In the combat task scenario, each object is an independent and distinct entity. When multiple entities carry out actions in parallel, it is necessary to have a unified description of the task scenario elements. Therefore, it is particularly necessary to establish a credible, consistent and application system-independent task scenario fusion model. Representing the task scenario through a unified model not only helps to accurately describe the information of elements such as the external situation environment, network environment impact, and internal cross-linkage environment, but also helps the dynamic sharing and reuse of knowledge.

[0139] (1) The main information sources of the task scenario fusion model

[0140] When information-based equipment is performing combat tasks, it is equipped with a variety of sensors to obtain battlefield information. These sensors will detect the same area or different areas and transmit the detected information to the combat intelligence command system. Usually, the targets entering the combat area will involve various information categories, such as spatial geometric information, infrared information, flow field information, active or passive electromagnetic information, etc. Taking the single-ship combat intelligence command system as an example, according to the sensors configured on the ship and the target environment of the battlefield, the main information sources involved in the task scenario fusion modeling of the single-ship combat intelligence command system are as Figure 4 shown.

[0141] For the combat scenario of a naval fleet, the task scenario fusion modeling becomes more complex due to the increased mutual information exchange among fleet members. In addition to the requirements similar to those of a single ship, the following three situations should be mainly considered: (1) Cooperative positioning of multiple ships for multiple surface targets; (2) Re-fusion processing of the fused information of multiple ships; (3) Navigation error, time synchronization error, and coordinate system selection issues.

[0142] (2) Task Scenario Fusion Model and Its XML Representation

[0143] The task scenario fusion model is essentially a general data structure suitable for describing task scenarios. After adding data reflecting the details of the task scenario, an understanding of the task scenario is formed. In this section, a detailed design of the top-level structure of the task scenario fusion model for information-based equipment is carried out. The task scenario model (Model) consists of a set of slots (Slot) describing the task scenario, and each slot can contain multiple facets (Facet), and each facet has its own name and value.

[0144] Considering that the representation methods suitable for various concepts in the military field are different, in order to achieve the consistency of the representation of various types of knowledge in the computer, a unified language needs to be used to describe it. XML is a platform-independent extensible markup language, which can be used to standardize the representation of the task scenario fusion model. The domain knowledge described by the XML language can be very conveniently extended, reused, and interoperated. Taking the task scenario of "troop maneuver" as an example, the XML representation of this task scenario fusion model is as Figure 5 shown. When actually carrying out the task scenario fusion modeling of information-based equipment, each facet can be further refined according to the actual military field and command level, using an appropriate granularity.

[0145] Through the above technical solutions, it can be seen that the method for task scenario analysis and fusion modeling of information-based equipment provided in the above embodiments of the present invention starts from the engineering practice, deeply explores the task scenario analysis and fusion modeling methods suitable for the characteristics of information-based equipment, and helps to further improve the quality and efficiency of task scenario analysis and modeling of information-based equipment. The subsequent research work can be carried out from the following two aspects:

[0148] (2) Technology for Constructing Software Test Profiles and Generating Test Cases for Information-Based Equipment

[0149] Constructing the test profile of informatization equipment software is essentially to model the possible operating states, usage modes and their distributions of the software. On this basis, software test cases can be generated to simulate the possible operation and usage of the informatization equipment software, so as to timely discover and correct potential defects in the software and improve the quality level of the informatization equipment software.
