The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

As shown in Figure 1, the simulation software interactive control system of the present invention comprises:

The distributed node access module includes a node creation and destruction module, a node interface definition module, and a node data sending and receiving module. The functions of the node creation and destruction module are as follows: nodes can be created and destroyed freely, and nodes need to choose a channel where they are located and assign an ID number for themselves. The function of the interface definition module of the node is as follows: After the node is created, an external interface must be created to receive and send data. The data format in the interface must conform to certain rules. The interface data is composed of parameters, and each parameter can have its own An index number, size and data type. The functions of the node's data receiving and sending module are as follows: the sending of node data is completed by calling the API interface, and there is no need to care where the destination of the sent data is when sending data; when receiving data through the defined receiving interface, a callback is entered and exited Function to implement, whenever data is received this callback function will be called. The implementation process of the distributed node access module is as follows: the node is created, and the node object is created according to the selected simulation channel number and the simulation node number, and the node number determines the uniqueness of the node. Define the input and output ports of the node according to the functional characteristics of the node, and define the meaning of the data parameters of each port in detail. Send data through the output port, and receive data by registering a callback function. After the function of the node is completed, it needs to be destroyed to reclaim resources.

The graphical node control module includes a distributed node information acquisition module and a distributed node status monitoring module. When each node is created, when the node's input and output interfaces are created, and when the node is destroyed, a broadcast message will be sent to the outside, and other nodes will receive this message. The simulation nodes existing in the current simulation channel can be clearly known on any node. The implementation process of the graphical node control module is as follows: register a node control node, and the information sent by other nodes during initialization, destruction, registration of ports and parameters can be received by this node. Module node information and status will be displayed graphically.

The node information acquisition module and the node status monitoring module are the basis for realizing the graphical node display, monitoring and data flow control functions.

The specific functions of the data flow control and monitoring module are as follows: The graphical node management interface will provide a graphical display of all nodes, and the control of the data flow will be realized by the way of painting the connection. When the connection is created, changed, or deleted, it will Notify the two connected nodes; when data is sent, it will send data according to the address of the receiving node registered to the node itself, and the monitoring node will receive the data sent by all nodes. The data monitoring interface has waveform diagram, dashboard, Tables and other friendly interfaces that can display real-time data and data changes. The implementation process of the data flow control and monitoring module is as follows: After the node is registered, it needs to interact with other nodes for data, but the node itself does not know the existence of other nodes, so its data flow needs to be manually set, and the node displays the canvas In , the flow direction of the data flow is specified by means of connections. The data transmission and reception of all nodes can be monitored, and the data can be automatically parsed according to the meaning of the previously defined node parameters, and the data can be presented in the form of icons.

The specific functions of the data flow control and monitoring module are as follows: The graphical node management interface will provide a graphical display of all nodes, and the control of the data flow will be realized by the way of painting the connection. When the connection is created, changed, or deleted, it will Notify the two connected nodes; when data is sent, it will send data according to the address of the receiving node registered to the node itself, and the monitoring node will receive the data sent by all nodes. The data monitoring interface has waveform diagram, dashboard, Tables and other friendly interfaces that can display real-time data and data changes.

The visionbus internal bus provides a good solution. The visionbus internal bus formulates a set of simple communication protocols, realizes the distributed network access function, and has the characteristics of simple programming and convenient configuration. When deploying in the network, it is not necessary to specify the IP address of the opposite end in advance, and it has the characteristics of plug-and-play simulation nodes. There is no need to determine a clear order for the nodes in the bus in the visionbus to join or exit. The visionbus intrabus supports the creation of multiple channels in a physical network. The channels do not interfere with each other. A program on an emulation channel that can complete an independent part of a calculation or perform a function. An emulation node may have one or more input or output metadata stream ports, and may have one or more input or output tick control ports. The data that needs to interact with each other between simulation nodes is not limited in format; the simulation node can define input or output metadata flow ports. It is defined arbitrarily by the simulation node itself. The management platform of graphical simulation nodes based on the Visionbus internal bus can better manage all simulation nodes, and can determine the flow direction of simulation data in a graphical way, and provide a variety of data monitoring windows, which can be seen intuitively The change of data greatly improves the debugging efficiency in the simulation process.
