Description

Technical Field

[0001] This invention relates to the field of industrial automated host computer system technology, and in particular to a host computer I / O modular configuration system that supports full customization at the channel level. Background Technology

[0002] Supervisory Control and Data Acquisition (SCADA) software is specialized software for data acquisition and monitoring control. It enables the rapid construction of industrial automation control systems through modular combinations, supporting functions such as real-time data acquisition, device communication, and human-machine interface development. While existing patent CN115629864 A proposes the concept of a programmable configuration system, it does not address the issues of modular configuration and flexible channel-level configuration. CN 118175124 A, although involving the concept of modularity, focuses more on lower-level machine configuration.

[0003] It is evident that traditional configuration software has the following drawbacks:

[0004] When configuring a chassis using traditional configuration software, the chassis selection is limited to pre-designed template chassis with fixed slot numbers. If you want to add or delete slots, the programmer has to modify the code, resulting in a long development cycle.

[0005] Traditional configuration software can only use built-in IO configuration templates, which cannot be modified, meaning the number of channels cannot be freely added. Since built-in templates can only collect the same data type at a time, they cannot meet the requirement of a single IO module collecting multiple data types. This does not satisfy the need for modularity.

[0006] For the same acquisition channel, it cannot meet the requirement of inconsistent data types and attributes acquired by different acquisition channel numbers. Traditional acquisition type templates contain multiple variable attributes, but many of these are useless, consuming transmission bandwidth and reducing transmission efficiency. This also fails to meet personalized customization needs.

[0007] Traditional configuration software does not meet the requirements of triple redundancy design, that is, it can only configure one slave device at a time. It also does not meet the requirements of personalized triple redundancy configuration, that is, it only needs to configure one slave device and automatically generate configuration files for the other two slave devices.

[0008] Traditional configuration software cannot automatically generate relevant configuration settings on the host computer's configuration page after the hardware device is assembled. It is necessary to manually align the configuration settings of the host computer software with the actual hardware device status. In other words, the configurations of the host computer and the host computer must be consistent; otherwise, the configuration file cannot be configured and will not take effect. Summary of the Invention

[0009] In view of the above problems, the present invention provides a host computer I / O modular configuration system for overcoming or at least partially solving the above problems.

[0029] The key parameters of the DO include the output mode and the security status.

[0030] Preferably, the custom module is used to implement custom-added chassis attributes, custom-added module attributes, and custom-added channel-level attributes;

[0033] The newly added custom channel-level attributes include custom configuration of physical channels and configuration of attributes for each channel.

[0034] Preferably, the configuration system is also used to receive the current device configuration status uploaded by the lower-level hardware via the network, so that the upper-level computer can generate relevant configuration configuration files and interface configuration displays in real time.

[0035] Preferably, the configuration system is also used to display the changes in real time on the host computer configuration interface after the hardware device is hot-swapped; and after the configuration is modified and saved, the relevant configuration file will be sent to the slave computer, which will run immediately after receiving the new configuration file.

[0111] Module:

[0112] like Figure 2As shown, to add a new module: enter the module name, select the number of channels, and select the channel address sorting method.

[0113] Editing module: Select the channel number, right-click and select the channel type.

[0114] Channel level:

Physical channels can be customized. Each channel's attributes can be configured independently, such as module parameters like range, filtering, and alarms, or custom parameters can be added.

[0116] 3. Dynamic reconfiguration and hot-swapping.

[0117] Runtime modification: No need to restart software and hardware devices. After the template configuration file is downloaded for the first time, the lower-level machine will upload the current device configuration status on the hardware device to the upper-level machine in real time via the network. The upper-level machine will also generate the relevant configuration configuration file and interface configuration display in real time.

[0118] Hot-swappable: After hot-swapping hardware devices, the changes will be displayed in real time on the host computer configuration interface; after the host computer modifies and saves the configuration, the relevant configuration file will be immediately sent to the slave computer (this happens automatically and requires no additional operation from the user), and the slave computer will run it immediately upon receiving the new configuration file.

[0119] It updates in real time online without requiring a restart; relevant configuration parameters are updated directly online.

[0120] 4. Visual configuration.

[0121] Provides a 3D configuration interface, supporting:

[0122] Physical view: Displays the actual layout of the modules.

[0123] Logical view: Drag-and-drop signal flow configuration.

[0124] Performance monitoring view: Displays various channel attribute values ​​in real time.

[0125] It is understood that the workflow of the host computer I / O modular configuration system provided in this application embodiment is as follows: Figure 4 As shown. Simultaneously, the host computer can connect to three slave computers, forming a triple redundancy system with one active and two backups, as shown. Figure 5As shown, the configuration system deployed on the host computer can generate three configuration files simultaneously. If a fault occurs in the currently controlling slave device, the status of the other two slave devices can be assessed, and one can be selected to take over control. Because the host computer uploads its operating parameters in real time during operation, each configuration file configured by the host computer is identical to the currently controlling slave device, ensuring that the slave device taking over can immediately perform the same operations as the current slave device.

[0126] In summary, the host computer I / O modular configuration system provided in this application solves the problem of manually aligning configuration information with the lower-level machine (actual hardware device) configuration information required by traditional configuration software. It can automatically align the upper and lower-level machine configuration configurations with a single click. Under multiple redundant configurations (i.e., multiple master control MCUs), it achieves multiple configurations generated from a single configuration, adapting to different MCUs. The new I / O configuration significantly improves development efficiency, moving away from requiring source code modification to configuration configuration. Through channel-level optimization, the number of modules used is reduced; only the necessary channels and attributes need to be configured, greatly reducing bandwidth requirements and data transmission volume. Customized hardware for different projects can be quickly implemented through configuration without hardware modification. Configuration files can be modified online in real time, taking effect immediately. The system automatically obtains the hardware device configuration status and changes, generates relevant configuration files, and displays them on the configuration interface.

[0127] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

Based on this understanding, the technical solution of this application, in essence, or the part that contributes to the prior art, can be embodied in the form of a software product.
