[0002] With the development of information technology, physical input / output (IO) devices are increasingly used in computer systems. These physical IO devices usually exchange data with a master device (such as a computer processor) to meet various data processing needs. However, the traditional direct connection between physical IO devices and master devices has some problems and limitations: 1) Lack of flexibility: The connection between traditional IO devices and master devices is usually fixed, which makes the system inflexible when dealing with changing IO requirements. 2) Low resource utilization: In traditional IO device management, the resource utilization of physical IO devices is often not high, especially in a multi-tasking environment. 3) Poor scalability: As the scale of the system expands, the number and types of physical IO devices also increase, which brings challenges to the expansion of the system.

[0063] See also Figure 1 , Figure 1 A virtual IO module communication control method provided by the present application comprises the following steps:

[0064] S1. Modularize the physical IO devices and determine the configuration requirements of the virtual IO modules.

[0065] Specifically, in this embodiment, the carrier of the virtual IO module is a bus module. The bus module is also called a bus device, which can control the bus and is the underlying data communication network in the field of automation. The bus module is used in the production site to connect the two-way transmission and branch structure communication network of the intelligent field equipment and the automation control system, and can exchange data with other communicative devices.

[0066] Specifically, the physical IO device is fixed on the bus module and is configured as one or more interfaces such as a connection interface, an Ethernet network interface, a USB interface, etc., which are not specifically limited here.

[0067] Specifically, in this embodiment, the physical IO devices arranged on the bus module are modularized, that is, each physical IO device is defined as an independent module, each module has a unique identifier and configurable parameters, wherein the configurable parameters include read / write speed, capacity, interface type, etc.

[0068] It is worth mentioning that modularizing physical IO devices can simplify the management and configuration process and improve the flexibility of the system.

[0069] Specifically, in this embodiment, the system further analyzes the requirements of the virtual IO module, including the required read and write speeds, data transfer rates, response times, memory size, CPU occupancy, bandwidth, etc., in order to evaluate the compatibility between the virtual IO module and the physical IO device and ensure that the virtual IO module can be effectively mapped to the physical IO device.

[0070] S2. Configure the virtual IO module according to the number of physical IO devices and the requirements of the virtual IO module, and generate a configuration file.

[0071] Specifically, in this embodiment, the virtual IO modules are configured according to the number of physical IO devices and the requirements of the virtual IO modules to ensure that each virtual IO module can be effectively mapped to the corresponding physical IO device. It can be understood that in this embodiment, the number of physical IO devices and virtual IO modules can be set according to user requirements and is not specifically limited here.

[0072] Specifically, in this embodiment, the generated configuration file is used to record the mapping relationship and configuration parameters between the virtual IO module and the physical IO device, and the configuration file will serve as the basis for subsequent data mapping table creation, data transmission channel initialization, etc.

[0073] Specifically, before generating a configuration file, the system creates a configuration file template, which is used to define the format and structure of the configuration file. When generating a configuration file, the corresponding parameters are filled into the configuration file template according to the number of physical IO devices and the requirements of the virtual IO module. These parameters include but are not limited to: the identifier of the virtual IO module, the identifier of the physical IO device mapped to it, the performance parameters of the virtual IO module (such as bandwidth, IOPS, etc.), and the configuration information of the physical IO device (such as interface type, queue depth, etc.).

[0074] It is worth noting that this application stores configuration files in a secure and easily accessible location for system management and maintenance.

[0075] S3. Create a data mapping table according to the configuration file, and implement the original mapping between the virtual IO module and the physical IO device according to the data mapping table.

[0076] Specifically, the data mapping table, as a logical structure, defines the corresponding relationship between the virtual IO module and the physical IO device. In this embodiment, creating the data mapping table according to the information in the configuration file can ensure that data is correctly transmitted from the virtual IO module to the corresponding physical IO device.

[0077] Specifically, in this embodiment, the configuration file is first parsed, then read, and after the configuration parameters of the virtual IO module and the physical IO device are extracted, the key parameters in the configuration file, such as the virtual IO module ID, the physical IO device ID, and performance parameters, are parsed.

[0078] Specifically, in this embodiment, when creating a data mapping table, the data mapping table is initialized to create an empty data mapping table structure, which is used to store the mapping relationship. After the system parses the key parameters in the configuration file, each virtual IO module is associated with the corresponding physical IO device, and the association relationship is filled into the empty data mapping table, thereby realizing the original mapping between the virtual IO module and the physical IO device.

[0079] Specifically, in this embodiment, the format of the data mapping table is set to one of CSV, XML, and a database table, and the format of the data mapping table is not specifically limited herein.

[0080] S4. Initialize the data transmission channel between the virtual IO module and the physical IO device according to the configuration file and the data mapping table.

[0081] Specifically, in this embodiment, the data transmission channel between the virtual IO module and the physical IO device is initialized according to the configuration file and the data mapping table, so as to configure the communication path between the virtual IO module and the physical IO device to ensure that the virtual IO module and the physical IO device can start exchanging data.

[0082] Specifically, in this embodiment, according to the information in the configuration file and the data mapping table, a data transmission channel is configured for each mapping relationship between the virtual IO module and the physical IO device, and necessary system resources such as network bandwidth and cache size are allocated to the data transmission channel.

[0083] Furthermore, the present application also verifies whether the data transmission channel is operating normally by sending a test data packet. In addition, the present application records the initialization state of each data transmission channel for subsequent monitoring and management.

[0084] S5. Control the physical IO device, the virtual IO module and the main control device to achieve normal data flow transmission.

[0085] S6. Monitor the IO requirements of physical IO devices and virtual IO modules in real time to capture changes in requirements.

[0086] Specifically, in this embodiment, by real-time monitoring of the IO requirements of the physical IO devices and the virtual IO modules, it is ensured that the system can respond to changes in the IO requirements in a timely manner, thereby maintaining the efficiency and reliability of data transmission.

[0087] Specifically, in this embodiment, the system collects IO demand data in real time. The IO demand data includes but is not limited to the number of read and write times, data volume, operation type, OPS (input / output operations per second), etc. The collected IO demand data is transmitted to the main control device, and the main control device analyzes the demand changes of the physical IO devices and virtual IO modules based on the IO demand data.

[0088] S7: When the IO demand is detected to exceed the preset threshold, the preset IO scheduling algorithm is automatically triggered.

[0089] Specifically, in this embodiment, the system collects IO demand data in real time for integrated quantification, so as to make a comprehensive judgment on the IO demand data. When the IO demand of the physical IO device and the virtual IO module changes and the IO demand exceeds the preset threshold, the preset IO scheduling algorithm is automatically triggered, so that the application can automatically adjust resource allocation.

[0090] S8. Dynamically configure the mapping relationship between the virtual IO module and the physical IO device according to the IO scheduling algorithm.

[0091] Specifically, the IO scheduling algorithm is used to dynamically reallocate the mapping relationship between virtual IO modules and physical IO devices according to the current IO demand and workload, thereby optimizing the data flow path and resource utilization.

[0092] S9. Optimize the data flow transmission path according to the adjusted mapping relationship between the virtual IO module and the physical IO device to achieve efficient data transmission.

[0093] Specifically, in this embodiment, the optimal data stream transmission path is determined according to the adjusted mapping relationship between the virtual IO module and the physical IO device.

[0094] Further, according to the optimized path, the data transmission channel between the virtual IO module and the physical IO device is reinitialized, so that normal data flow transmission can be performed between the physical IO device, the virtual IO module and the main control device. Therefore, the present application can achieve more efficient data transmission after the mapping relationship is adjusted, thereby improving the performance of the overall system.

[0095] In summary, the present application provides a virtual IO module communication control method. In this solution, by modularizing the physical IO device and determining the configuration requirements of the virtual IO module, the management and configuration process can be simplified. The virtual IO module is configured according to the number of physical IO devices and the requirements of the virtual IO module, and a configuration file is generated. The configuration file will serve as the basis for subsequent data mapping table creation, data transmission channel initialization, etc. A data mapping table is created according to the configuration file, and the original mapping between the virtual IO module and the physical IO device is implemented according to the data mapping table, so that the corresponding relationship between the virtual IO module and the physical IO device can be confirmed. According to the configuration file and the data mapping table, the data transmission channel between the virtual IO module and the physical IO device is initialized to ensure that the data is transmitted according to the established path and improve the reliability of the transmission. Control the normal data flow transmission between the physical IO device, the virtual IO module and the main control device. The IO requirements of the physical IO device and the virtual IO module are monitored in real time, and the demand changes are captured, so that the system can respond to the IO demand changes in a timely manner. When the IO demand is detected to exceed the preset threshold, the preset IO scheduling algorithm is automatically triggered. The mapping relationship between the virtual IO module and the physical IO device is dynamically configured according to the IO scheduling algorithm, thereby optimizing the data flow path and resource utilization. According to the adjusted mapping relationship between the virtual IO module and the physical IO device, the data flow transmission path is optimized to achieve efficient data transmission. Therefore, the present invention can achieve effective expansion of IO input and output, improve the data transmission efficiency of the bus IO module, and has high reliability.

[0096] Based on the above embodiments:

[0097] See also Figure 2 , Figure 2 A framework schematic diagram of a virtual IO module communication control method provided in this application.

[0098] See also Figure 3 , Figure 3 A flowchart of another virtual IO module communication control method provided in this application.

[0099] As a preferred embodiment, a virtual IO module communication control method further includes:

[0100] S10, classifying each virtual IO module into processing levels.

[0101] Specifically, in this embodiment, the performance requirements and business criticality of each virtual IO module are evaluated. The performance requirements include bandwidth requirements, I / O operation frequency, response time requirements, etc., and the business criticality includes the urgency of data processing, etc., which are not specifically limited here.

[0102] Specifically, in this embodiment, according to the evaluation results, the virtual IO modules are divided into different processing levels, such as level A (critical), level B (important) and level C (general). In addition, the level division of each virtual IO module can also be customized according to user requirements, which is not specifically limited here.

[0103] It is worth noting that the present application can distinguish the importance and priority of virtual IO modules through level classification, so that key business needs can be guaranteed in terms of transmission.

[0104] S11. Identify the virtual IO module with a high processing level, and reserve a corresponding physical IO device for the virtual IO module with the high processing level.

[0105] Specifically, in this embodiment, a unique identification tag is assigned to each virtual IO module, and modules with high processing levels are specifically marked.

[0106] In one embodiment, a field is set in the configuration file of the virtual IO module to record the processing level of the virtual IO module, and the field is encrypted to ensure security.

[0107] S12. Fix the mapping relationship between the virtual IO module with a high processing level and the corresponding physical IO device to avoid dynamic allocation.

[0108] Specifically, in this embodiment, after the virtual IO modules classified as Class A are clearly defined, the mapping relationship between the virtual IO modules of Class A and the reserved physical IO devices is set to static, and specific physical IO devices are statically allocated to the virtual IO modules of the high processing level.

[0109] Furthermore, a list is created for the virtual IO modules classified as class A, the list including detailed information such as the name, identification, and performance requirement of the virtual IO modules.

[0110] Furthermore, a physical IO device with stable performance and sufficient capacity is selected as a reserved resource, and after determining a unique identifier of the physical IO device such as a device ID, each class A virtual IO module is directly mapped to a specific physical IO device.

[0111] See also Figure 4 , Figure 4 A flowchart of a mapping relationship between a virtual IO module and a physical IO device is provided for dynamically configuring the mapping relationship between the virtual IO module and the physical IO device according to an IO scheduling algorithm.

[0112] As a preferred embodiment, dynamically configuring the mapping relationship between the virtual IO module and the physical IO device according to the IO scheduling algorithm includes:

[0113] S81. Evaluate the original mapping relationship between the virtual IO module and the physical IO device.

[0114] Specifically, in this embodiment, the system first collects the original mapping relationship data between the current virtual IO module and the physical IO device, and then further analyzes key performance indicators such as delay, bandwidth utilization, error rate, etc. during data transmission.

[0115] Specifically, the present application evaluates the quality of the original mapping relationship between the virtual IO module and the physical IO device by comparing the actual performance index with the preset performance standard.

[0116] S82. Calculate a new optimal mapping relationship based on the original mapping relationship and the IO scheduling algorithm.

[0117] S83. Generate a new mapping configuration file based on the calculation result.

[0118] Specifically, in this embodiment, the calculated optimal mapping relationship is converted into a configuration file format. The mapping relationship between the virtual IO module and the physical IO device is clearly defined in the configuration file, including information such as device number and port number, and the configuration file is saved for subsequent calls.

[0119] S84. Re-establish the connection between the virtual IO module and the physical IO device according to the mapping configuration file.

[0120] Specifically, in this embodiment, the system reads a new mapping configuration file, obtains a new mapping relationship between the virtual IO module and the physical IO device, and then disconnects the current virtual IO module from the physical IO device.

[0121] According to the new mapping relationship, the data transmission channel between the virtual IO module and the physical IO device is re-established.

[0122] Furthermore, the present application also verifies the new mapping relationship to ensure that data transmission proceeds normally.

[0123] See also Figure 5 , Figure 5 A flowchart for calculating a new optimal mapping relationship based on an IO scheduling algorithm is provided for this application.

[0124] As a preferred embodiment, calculating a new optimal mapping relationship according to the original mapping relationship and the IO scheduling algorithm includes:

[0125] S821. Compare the current load parameters of each physical IO device.

[0126] Specifically, in this embodiment, before calculating the new optimal mapping relationship, the system first collects the load parameters of the physical IO devices and compares and analyzes the collected load parameters, wherein the load parameters include CPU usage, memory usage, I / O operation rate, etc., which are not specifically limited here.

[0127] It is worth noting that, by evaluating the current working status of each physical IO device and performing comparative analysis on the load parameters, the present application can identify which physical IO devices are in a high-load state and which physical IO devices still have the ability to handle more tasks, thereby achieving good load balancing and data transmission optimization processing.

[0128] S822. Allocate a different weight to each physical IO device according to the comparison result.

[0129] Specifically, in this embodiment, the system defines a weight value for each physical IO device according to the current load of each physical IO device.

[0130] It is worth noting that, by assigning different weights to different physical IO devices, the present application quantifies the ability of each physical IO device to handle additional loads, thereby more accurately reflecting the processing capacity of each physical IO device.

[0131] S823. Calculate a new optimal mapping relationship based on the allocation result.

[0132] Specifically, in this embodiment, an IO scheduling algorithm is used to calculate a new mapping relationship. Based on the algorithm calculation result, a new mapping relationship between the virtual IO module and the physical IO device is generated.

[0133] Specifically, in this embodiment, when there are multiple virtual IO modules and multiple physical IO devices, the IO scheduling algorithm for dynamically adjusting the mapping relationship needs to consider the requirements of all virtual IO modules and the load conditions of all physical IO devices.

[0134] Specifically, in this embodiment, the specific formula of the IO scheduling algorithm is: .

[0135] in:

[0136] Indicates virtual IO module Decision variables mapped to physical IO device i.

[0137] P represents the collection of physical IO devices.

[0138] V represents a collection of virtual IO modules.

[0139] Indicates the current load of physical IO device i.

[0140] Indicates the weight of physical IO device i, reflecting the processing capability or priority of the physical IO device.

[0141] Is a function used to quantize the virtual IO module The impact of demand on the physical IO device i load.

[0142] The argmin function is used to indicate the value of the independent variable that makes the function reach the minimum value.

[0143] Specifically, in this embodiment, for each physical IO device i, the total load is the current load Add the sum of the impact of all virtual IO modules on its load .

[0144] Specifically, in this embodiment, the calculated total load is divided by the weight of the physical IO device. , in order to adjust the load calculation so that it can reflect the actual processing capacity of the physical IO device.

[0145] Specifically, when making a mapping decision, for each virtual IO module, a physical IO device that minimizes the above calculation result is selected for mapping, ensuring that each virtual IO module can be mapped to the physical IO device that best suits its needs.

[0146] It is worth noting that the IO scheduling algorithm formula of this application is explained as follows: for each virtual IO module Reselect a physical IO device i so that the total load of the physical IO device (current load Add virtual IO module Demand for this equipment , and then divided by the weight of the device ) minimum. Therefore, this application can ensure that each virtual IO module They are all mapped to the physical IO device that best suits their current needs, thereby achieving load balancing and efficient use of resources.

[0147] As a more specific example, assume there are 3 physical IO devices (P1, P2, P3) and 2 virtual IO modules (V1, V2). Each physical IO device has a weight (W) and a current load (L), and each virtual IO module's demand for the physical IO device is expressed by a function To express.

[0148] The following is a simplified data of physical IO devices and virtual IO modules:

[0149] Physical IO devices:

[0150] P1: weight W1 = 3, current load L1 = 20;

[0151] P2: weight W2 = 2, current load L2 = 10;

[0152] P3: weight W3 = 1, current load L3 = 5;

[0153] Virtual IO module:

[0154] V1: Demand for P1 f(V1, P1) = 5, demand for P2 f(V1, P2) = 3, demand for P3 f(V1, P3) = 2;

[0155] V2: Demand for P1 f(V2, P1) = 4, Demand for P2 f(V2, P2) = 6, Demand for P3 f(V2, P3) = 1;

[0156] Mapping the decision process:

[0157] For Virtual IO Module V1:

[0158] Calculate the total load on each physical IO device (including V1 demand):

[0159] P1: ;

[0160] P2: ;
