detailed description

In order to make the present invention easier to understand, specific embodiments of the present invention will be further described below.

A circuit modeling method for a simulation training system, comprising:

S1, digitalization of the system schematic diagram, including decomposing the circuit, establishing its structural relationship, and storing component information in a hierarchical relationship.

When the system performs circuit virtualization, the system circuit is first divided into multiple graphs according to the function, each graph corresponds to one or more circuits, each circuit is composed of a hybrid circuit, and a hybrid circuit is composed of series or parallel circuits, where Parallel circuits are composed of series circuits, and series circuits can be composed of parallel circuits and components. The components of various types of circuits include: voltage source (hydraulic source), control components, actuators and auxiliary components.

The characteristic of the series circuit is that the current is from high voltage to low voltage. Therefore, the components on the same series circuit at the time of design are at the same level when stored, the high voltage is at the initial position, and the low voltage is at the terminal position. When the high voltage of the series circuit is the required voltage, the control components are in the working state, and all the components function normally, the series circuit works.

Each parallel circuit consists of at least one series circuit. Therefore, the parallel circuit is designed as a container containing only series circuits. When only one series circuit in the parallel circuit is in working condition, the parallel circuit is in working condition. When the parallel circuit is in operation, the connected series circuit is in operation.

A hybrid circuit is composed of one or more series circuits or parallel circuits, and can be regarded as a series circuit with a parallel circuit in terms of its function. Therefore, the hybrid circuit is designed as a series circuit including parallel circuits and components. When the components and parallel circuits in the series circuit are in the working state, the hybrid circuit is in the working state.

S2, computer reconstruction of the system schematic diagram, modeling and displaying the digital schematic diagram obtained in S1 in the computer, including schematic diagram and component modeling, schematic diagram and component dynamic generation and display.

The method used in the modeling of the system is to decompose the system circuit into a hybrid circuit, a parallel circuit or a series circuit. Each circuit is composed of components with various functions. Class components are endowed with certain attributes, methods, and events. The state is set through the attributes, the functions are realized through the methods, and the actions are triggered through the events to realize the logical reasoning function.

In the process of circuit reconstruction, the main work of graphics is to generate circuits and display and locate circuits. The generation can be divided into three parts: series circuit generation module, parallel circuit generation module and hybrid circuit generation module. Through the series, parallel and hybrid circuit generation modules, the system can realize the positioning and display of the electrical schematic diagram and system modeling.

In the reconstruction process of components, each component is divided into component class and signal class, and the modeling shares one interface. All component classes have the same methods and attributes, but their implementation methods are different. The meaning expressed by the attributes Not the same.

S3, the realization of system logical reasoning, receiving external signals, and simulating system functions through logical reasoning to send out various control signals as required.

The logical reasoning of the system is divided into three parts: the first is the state change part, which mainly includes the state change during fault setting, the state change during the simulation operation and the switch input state of the simulated operation platform; the second is the reasoning part, which mainly completes the circuit reasoning when the state changes, and The third is the output interface part. When the state changes, the signal is mainly sent to the component state change, the simulation operation interface, the simulation operation platform, the circuit demonstration and the multimedia demonstration system.

In the reasoning process, in addition to the reasoning function of the circuit, there are also reasoning of some components, such as relays, voltage mechanisms, positive voltage input signals, positive voltage output signals, indicator lights, etc.

Taking the transmission and control power supply circuit as an example, Figure 1 represents the schematic diagram of the transmission and control power supply circuit. According to the schematic diagram, the digital hierarchical structure shown in Figure 2 is obtained by decomposing, and further according to the hierarchical structure, the storage as shown in Table 1 below is obtained. The structure table, in which the number is mainly used to express the hierarchical relationship of each component, series circuit and parallel circuit in the circuit, the interface is the address of the input and output interface corresponding to the analog console, and the initial state is that the component is assigned the initial state when it is generated. The status value and component type are used to distinguish each component during computer reconstruction of the system schematic diagram and system logic reasoning.

Object-oriented technology is used to reconstruct the system schematic diagram by computer, and the computer reconstruction diagram shown in Figure 3 is obtained, and the logic reasoning of the simulation training system is finally realized through the respective reasoning of the circuit and components, receiving electrical signals, and issuing corresponding control Signal.

In summary, the present invention proposes a new method for establishing a physical model of a comprehensive test system circuit through the attributes, methods and events of components, circuits and stand-alone devices using object-oriented technology, and performs comprehensive test system fault diagnosis and troubleshooting capabilities according to the forces To meet the needs of training, use object-oriented technology to design series circuits, parallel circuits, hybrid circuits and various components in the circuit, assign certain attributes, methods and events, set the state through attributes, realize its functions through methods, and trigger events through events Its action, after modeling the system circuit schematic diagram, displays it in the form of structural graphics and displays the circuit working status in real time, realizing the logical reasoning of the comprehensive testing process; setting the fault settings of components and circuit attributes through system status settings, changing various components The properties of the device realize the simulation of the failure of each equipment in the comprehensive test system, and solve the problem that there is no technical means for the maintenance and training of a certain type of missile comprehensive test equipment that has plagued the army for a long time.
