[0044] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0045] like Figure 1As shown, the present application relates to a data acquisition system, which includes an industrial server 110 and multiple data acquisition devices 120. The industrial server 110 establishes a peripheral component interconnect express (PCIe) connection with each data acquisition device 120, and the data collected by each data acquisition device 120 is summarized through PCIe.

[0046] The multi-core heterogeneous chip (System on Chip, SOC) in each data acquisition device 120 includes a resource management domain 121 and multiple data acquisition domains 122. The resource management domain 121 is used to allocate resources in the security domain to each data acquisition domain 122. An application process runs in each data acquisition domain 122, and the application process performs data acquisition through the allocated resources.

[0047] like Figure 2 As shown, it shows a method flow chart of a cross-device resource configuration method provided by an embodiment of the present application, and the cross-device resource configuration method can be applied to a data acquisition system. The cross-device resource configuration method may include:

[0048] Step 201 , when configuring resources for at least one data acquisition domain in a data acquisition device, the industrial server controls the resource management domain in the data acquisition device to modify a firewall, where the firewall is used to limit resource access rights of at least one data acquisition domain.

[0049] The resource management domain can use a firewall mechanism to manage resources in the security domain. The resource management domain can configure the firewall to limit the resource access rights of each data collection domain through the firewall.

[0050] Step 202: the industrial server configures resources for relevant registers in the data acquisition device through the pre-mapped BAR space, resets and initializes the configured resources, and notifies at least one data acquisition domain to start an application process through the resource management domain.

[0051] The Base Address Register (BAR) space is a set of registers used to map I / O ports or memory address space.

[0052] After starting the data acquisition device, the data acquisition device will configure the relevant registers as BAR space and map it to the industrial server through PCIe. The industrial server can access the relevant registers through the BAR space, configure resources for the relevant registers, and reset and initialize the configured resources.

[0053] After the initialization of the resources is completed, the industrial server can send a notification to the resource management domain through PCIe, and the resource management domain sends a notification to the data collection domain to notify it to start the application process for data collection.

[0054] Step 203: at least one data collection domain starts an application process, where the application process is used to collect data using the reconfigured resources.

[0055] The data collection domain starts the application process after receiving the notification sent by the resource management domain, and each application process collects data through the reconfigured resources.

[0056] To summarize, in the cross-device resource configuration method provided by the embodiment of the present application, the industrial server modifies the firewall through the resource management domain in the data acquisition device to limit the resource access rights of each data acquisition domain; then, the industrial server configures the resources of the data acquisition device based on the pre-mapped BAR space; finally, the application process in the data acquisition domain is restarted to perform data collection through the reconfigured resources, so that resources can be allocated to the data acquisition domain without re-burning the partition, which can save time and hardware costs; the security level of the data acquisition domain can be dynamically adjusted through the firewall mechanism to enhance the security of the data acquisition domain; and resource allocation can be dynamically adjusted to maximize resource utilization.

[0057] like Figure 3 As shown, it shows a flow chart of a cross-device resource configuration method provided by an embodiment of the present application, and the cross-device resource configuration method can be applied to a data acquisition system. The cross-device resource configuration method may include:

[0058] Step 301: The industrial server establishes a PCIe connection with a data acquisition device.

[0059] like Figure 4 As shown, the industrial server is started, and the industrial server initializes the root complex (RC) end; the data acquisition device is started, and the data acquisition device initializes the terminal (End Point, EP); the industrial server establishes a PCIe connection with the terminal in the data acquisition device through the RC end.

[0060] Step 302: The data acquisition device configures the BAR space of the relevant registers and maps the BAR space to the industrial server.

[0061] A BAR space is a set of registers used to map I / O ports or memory address space.

[0062] After starting the data acquisition device, the data acquisition device will configure the relevant registers as BAR space and map it to the industrial server through PCIe. The relevant registers include resource configuration (SD card Configuration Register, SCR) registers and inter-processor communication (Inter-Processor Communication Registers, IPC) registers. The SCR register is used to store firewall rules, and the IPC register is used to store the address of the configured resources.

[0063] Step 303: before configuring resources for at least one data acquisition domain, the industrial server sends application process closing information to the resource management domain via PCIe.

[0064] When reconfiguring the resources of the data collection domain, the application process in the data collection domain may be using the originally allocated resources for data collection. It is necessary to notify the data collection domain to close the application process and release the resources so that the resources can be reallocated.

[0065] Figure 5 In the process, the Windows device (i.e., industrial server) can send application process shutdown information to the resource management domain through PCIe.

[0066] Step 304: The resource management domain receives information about closing the application process through PCIe, and notifies at least one data collection domain to close the application process through inter-core communication.

[0067] Figure 5 In the process, the resource management domain in the data acquisition terminal (ie, the data acquisition device) receives the information of closing the application process, and notifies the application data acquisition domain (ie, the data acquisition domain) to close the application process.

[0068] Step 305: at least one data collection domain closes the application process and releases corresponding resources.

[0069] The data collection domain can also cache the collected data to avoid data loss.

[0070] Figure 5 In the process, the application data collection domain (i.e., data collection domain) receives the notification through inter-core communication, closes the application process and releases the corresponding resources.

[0071] Step 306: After completing the resource release, the data collection domain sends resource release completion information to the resource management domain through inter-core communication.

[0072] Step 307: The resource management domain receives resource release completion information through inter-core communication, and sends resource release completion information of each data collection domain to the industrial server through PCIe.

[0073] Step 308: The industrial server receives resource release completion information of each data collection domain through PCIe, and after determining that all related data collection domains have completed resource release, triggers resource configuration for at least one data collection domain.

[0074] The relevant data collection domain refers to the data collection domain that needs to be configured with resources, which may be all the data collection domains in a data collection device or part of the data collection domains in a data collection device.

[0075] The industrial server can periodically detect whether the relevant data collection domains have completed resource release; if the relevant data collection domains have completed resource release, it is determined that the preparation work is completed and resource allocation can be performed; if there are still data collection domains that have not completed resource release, continue to wait.

[0076] Step 309, when configuring resources for at least one data acquisition domain in the data acquisition device, the industrial server controls the resource management domain in the data acquisition device to modify the firewall, where the firewall is used to limit resource access rights of at least one data acquisition domain.

[0077] The resource management domain can use a firewall mechanism to manage resources in the security domain. The resource management domain can configure the firewall to limit the resource access rights of each data collection domain through the firewall.

[0078] Specifically, the resource management domain in the industrial server control data acquisition device modifies the firewall, which may include:

[0079] (1) The industrial server sends firewall modification information to the resource management domain through PCIe. The firewall modification information is used to specify resource access rights of at least one data collection domain.

[0080] (2) The resource management domain receives firewall modification information through PCIe, modifies the firewall according to the firewall modification information, and sends firewall modification success information to the industrial server through PCIe.

[0081] (3) The industrial server receives firewall modification success information through PCIe.

[0082] The industrial server can periodically detect whether the resource management domain has completed the modification of the firewall; if the resource management domain has completed the modification of the firewall, the resource configuration is performed; if the resource management domain has not completed the modification of the firewall, the server continues to wait.

[0083] Step 310: the industrial server configures resources for relevant registers in the data acquisition device through the pre-mapped BAR space, resets and initializes the configured resources, and notifies at least one data acquisition domain to start an application process through the resource management domain.

[0084] The industrial server can access the relevant registers through the BAR space and configure the resources of the relevant registers, such as modifying the firewall rules in the SCR register and modifying the address of the resources in the IPC register. Then, the industrial server resets and initializes the configured resources.

[0085] After the initialization of the resources is completed, the industrial server can send a notification to the resource management domain through PCIe, and the resource management domain sends a notification to the data collection domain to notify it to start the application process for data collection.

[0086] Specifically, notifying at least one data collection domain to start an application process through a resource management domain may include:

[0087] (1) The industrial server sends information to start the application process to the resource management domain through PCIe.

[0088] (2) The resource management domain receives information about starting an application process through PCIe, and notifies at least one data acquisition domain to start the application process through inter-core communication.

[0089] Step 311: at least one data collection domain starts an application process, where the application process is used to collect data using the reconfigured resources.

[0090] The data collection domain starts the application process after receiving the notification sent by the resource management domain, and each application process collects data through the reconfigured resources.

[0091] In this application, the industrial server can perform resource configuration on the data acquisition domain in one data acquisition device, or it can perform resource configuration on the data acquisition domains in multiple data acquisition devices at the same time. When performing resource configuration on the data acquisition domains in multiple data acquisition devices at the same time, the address of the BAR space mapped in the industrial server for each data acquisition device is different, so as to distinguish different data acquisition devices.

[0092] To summarize, in the cross-device resource configuration method provided by the embodiment of the present application, the industrial server modifies the firewall through the resource management domain in the data acquisition device to limit the resource access rights of each data acquisition domain; then, the industrial server configures the resources of the data acquisition device based on the pre-mapped BAR space; finally, the application process in the data acquisition domain is restarted to perform data collection through the reconfigured resources, so that resources can be allocated to the data acquisition domain without re-burning the partition, which can save time and hardware costs; the security level of the data acquisition domain can be dynamically adjusted through the firewall mechanism to enhance the security of the data acquisition domain; and resource allocation can be dynamically adjusted to maximize resource utilization.
