[0062] File management subsystem, used to manage one or more of calibration parameter files, communication protocol files, and engineering information files;

[0063] The lower computer includes a control response subsystem corresponding to the control strategy of the upper computer.

[0064] Specifically, the product setting subsystem includes a product information confirmation module, which is used to determine product information through a product target selection list and transmit product parameters to the communication setting subsystem and the control algorithm setting subsystem.

[0065] Specifically, the control algorithm setting subsystem includes an algorithm providing module, which is used to provide available algorithms according to product information and interact with the lower computer to complete the control algorithm setting function.

[0066] Specifically, the communication setting subsystem includes a node sniffing trigger module, which is used to trigger the node sniffing function after the communication parameters are set, monitor the online target, and set the communication parameters of the lower computer.

[0067] Specifically, the parameter calibration subsystem includes a dynamic response module and an interface display module, which are used to dynamically respond according to the settings of the control algorithm setting subsystem and provide a parameter calibration interface corresponding to the control algorithm, wherein the parameter calibration interface has parameter reading and parameter downloading functions.

[0068] Specifically, the parameter setting module, interaction module, and waveform drawing module of the parameter simulation subsystem are used to set a variety of waveform parameters as dynamic target parameters, communicate interactively with the lower computer, and draw simulation waveforms online based on communication data to achieve online simulation of the control algorithm.

[0069] Specifically, the fault management subsystem includes a main body database and a fault data storage module, which are used to monitor and display the fault data generated during the operation of the upper / lower computer in real time, and store, delete and view historical fault data.

[0071] The bus end cover control hydraulic valve upper and lower computer interaction system provided in this embodiment, and its interaction method specifically involves the following process:

[0072] Figure 1The block diagram of the interactive system structure of the present invention. Among them, the product setting subsystem provides a product selection list that matches this interactive system. The communication systems and control algorithms supported by different products are not the same. The product selection results will transfer data to the communication setting subsystem and the control algorithm setting subsystem. The communication setting subsystem contains the communication protocol that matches the selected product, and the user sets the communication parameters according to the scene requirements. The control algorithm setting subsystem contains the control algorithm that matches the selected product, and the user switches the control algorithm according to the scene requirements. The parameter calibration subsystem contains the parameter calibration interface that matches the selected control algorithm, and the user can calibrate and test the control parameters involved in the algorithm through this subsystem. The parameter simulation subsystem can set the dynamic response target parameters and dynamic response waveforms, and interact with the lower computer to observe the response characteristics of the lower computer's execution action. The fault management subsystem is responsible for the fault information in the management process. The subsystem contains a local database function that can store, view, and delete fault information. The file management subsystem is responsible for managing files such as communication protocols, calibration data, and engineering information during the interaction process.

[0073] Figure 2 It is the main frame interactive flow chart for the operation of the host system. After the application terminal is started, it provides product types and control algorithms for selection. After initialization, enter the main interface window, and you can enter the communication setting subsystem, parameter calibration subsystem, parameter simulation subsystem, fault management subsystem, etc.

[0074] Enter the communication setting subsystem to select communication physical plug-in, communication port, communication baud rate and other parameters. After the parameter setting is completed, the initialization result will be displayed in the status bar of the main interface. The completion of communication initialization will trigger the sniffing mechanism, send sniffing instructions according to the selected protocol, detect the active unit of the lower computer, and display it in the main interface window according to the detection results. The process is as follows: Figure 3 shown.

[0075] The parameter calibration subsystem includes multiple calibration interfaces, which provide "Read" and "Update" commands. The "Read" command sends a read command containing the function module ID to the lower computer, expecting to receive the calibration parameters currently used by the lower computer for the module; the "Update" command sends a data command containing the function module ID to the lower computer, expecting the lower computer to replace the calibration parameters currently used with the received calibration parameters for the module. The process is as follows: Figure 4 shown.

[0076] The parameter simulation subsystem interface is as follows: Figure 5 As shown in the figure: the configuration options and display area are designed. The user needs to set the simulation parameters before the simulation starts. The simulation process is controlled by the host computer through instructions.

[0077] During the simulation process, the interaction layer calculates the simulation process communication data packets based on the parameters and simulation control algorithm. The communication data packets are transmitted in two ways: one is to calculate the packet content that needs to be sent to the lower computer based on the parameters of the simulation waveform, and the other is to calculate the packet content of the sensor data that needs to be obtained based on the sampling period. The two data are sent alternately in a cycle during the simulation process. The interaction layer parses the data and displays the received data waveform and parameter values ​​on the user layer. The interaction process is as follows: Figure 6 shown.

[0078] After entering the fault management subsystem, users can choose to actively query the fault history of the lower computer. The interactive layer creates and transmits the fault reading command and waits for ACK. The lower computer parses the command and uploads the fault code. After the interactive layer parses, the fault information is displayed in the status bar and fault record display interface. Users can choose whether to store the historical fault records to the local server. Among them, the lower computer will actively upload the fault code when a fault occurs. After the interactive layer parses, the fault information is displayed in the status bar and fault record display interface. The interactive process is as follows: Figure 7 shown.

[0079] To summarize, the bus end cover control hydraulic valve upper and lower computer interaction system and strategy of the present invention, by constructing a product setting subsystem, a control algorithm setting subsystem, a communication setting subsystem, a parameter calibration subsystem, a parameter simulation subsystem, a fault management subsystem, and a file management subsystem on the upper computer, and constructing a corresponding control response subsystem on the lower computer system, and combining the interactive control strategy between systems, can effectively solve the problem of high-reliability communication, calibration, and parameter simulation between the electronically controlled hydraulic valve system and the upper computer.
