It will be understood that the functions and steps shown in the present disclosure may occur in an order different from that shown without conflict.

Currently, when connecting I/O devices to PLCs, I/O access can only be implemented for single-location deployment scenarios. However, in multi-location cloud PLC deployment scenarios, different I/O devices have different industrial control service requirements. Therefore, it is impossible to meet the business needs of multi-location cloud PLC deployment scenarios on 5G networks.

In order to solve the above problems, the 5G cloud PLC deterministic transmission method provided by the present invention can obtain configuration information by detecting the I/O device. Since the base station to which the I/O device is connected can be known through the configuration information, the first access information can be determined to obtain the target I/O device and other I/O devices. At the same time, the access situation of the target I/O device and other I/O devices to the base station can also be obtained. Then, the control business information and communication link information of the I/O device are used to determine whether the business needs can be met. In this way, the access relationship between the PLC of the target base station and the I/O device can be determined, thereby achieving flexible allocation and routing between the PLC and the I/O device, and solving the problem that the multi-location deployment of the 5G network cloud PLC cannot be met.

Control service information can refer to querying device capabilities based on the model and version number in device information, and specifying I/O device parameters based on device capabilities. During each communication cycle, cloud-based industrial control services need to send a large number of data packets to the vast number of I/O devices at industrial sites.

In an embodiment of the present disclosure, a method for obtaining device information and configuration information of an I/O device may include:

Send a broadcast request to the network in the target command format and scan the I/O devices in the network;

According to the broadcast request, the I/O device receives the response information, which includes the physical cell identifier of the base station where the I/O device accesses, the device model, version number, and the IP address of the device;

A broadcast request may refer to an ARP (Address Resolution Protocol) request. ARP is a TCP (Transmission Control Protocol)/IP protocol that obtains a physical address based on an IP address. When a host sends information, it broadcasts an ARP request containing the target IP address to all hosts on the network and receives a return message to determine the target's physical address. After receiving the return message, the IP address and physical address are stored in the local ARP cache and retained for a certain period of time. The next request is made to directly query the ARP cache to save resources. In the embodiment of the present disclosure, determining the configuration information and device information of the I/O device may refer to the I/O&PLC management module sending a broadcast request to the network according to the instruction format provided by the I/O device manufacturer, scanning the I/O devices in the network, and requesting the return of the physical cell identifier of the base station to which the device is connected, the device model and version number in the request. After receiving the response from the I/O device, the module records the IP address and device information of the device.

In the embodiment of the present disclosure, the first access information may refer to grouping devices connected to the same base station according to the device configuration information PCI. If the same group of devices needs to work together, the device access information of the group is the first access information.

In an embodiment of the present disclosure, after obtaining configuration information, control service information, and communication link information of an I/O device, the method may further include:

Determining second access information according to the configuration information, where the second access information includes a target I/O device;

According to the second access information, the target I/O device is connected to the cloud PLC deployed in the base station.

The second access information may refer to the I/O device information accessed by the base station. The second access information and the first access information are both base station access information, but they represent different situations. The first access information represents that the target I/O device and other I/O devices access the same base station and work in coordination, while the second access information represents that only the target I/O device accesses the base station and does not need to work in coordination with other devices.

Determining the second access information according to the configuration information may refer to determining, according to the physical cell identifier of the base station to which the device is connected, that the target I/O device is not connected to the same base station as other I/O devices.

According to the second access information, accessing the cloud PLC deployed at the base station to the target I/O device may mean that based on the fact that the target I/O device does not access the same base station as other devices and does not collaborate with other devices, the cloud PLC deployed at the base station to which the target I/O device is connected is selected as its access instance to determine the path of the target I/O device.

S103: Determine, based on the control service information, a first access status between the target I/O device and the target base station, and a second access status between other I/O devices and the target base station.

In the disclosed embodiments, the second access situation may refer to a situation where another I/O device that needs to collaborate with the target I/O device has accessed the target base station.

Determining the first access status of the target I/O device and the target base station, and the second access status of other I/O devices and the target base station based on the control service information can refer to determining whether the devices that need to work together are connected to the same base station based on the collaborative relationship between the I/O devices.

The access relationship between the PLC of the target base station and the I/O device can refer to the relationship between the I/O device access to Cloud PLC and Local PLC. Among them, Cloud PLC can refer to the cloud PLC (CPLC), that is, the PLC that needs to be deployed in the cloud and is responsible for processing non-real-time tasks. Local PLC can refer to the PLC deployed near the I/O device at the industrial site and is responsible for real-time control of the I/O device. Due to the flexible deployment location of PLC, the access relationship between I/O devices and PLC is more complex. In the embodiment of the present disclosure, the access relationship between the PLC of the target base station and the I/O device may refer to the I/O device accessing the cloud PLC instance deployed on the base station and accessing the cloud PLC instance deployed on the 5G-MEC, or adopting a hierarchical access solution to connect the target I/O device to the cloud PLC deployed on the base station, and the cloud PLC completes the control business communication with the I/O device, and then the cloud PLC deployed on the base station is connected to the cloud PLC deployed on the 5G-MEC platform, and the cloud PLC deployed on the 5G-MEC platform completes the collaborative task processing between different I/Os.

Determining the access relationship between the PLC of the target base station and the I/O device based on the first access situation of the target I/O device and the target base station, the second access situation of other I/O devices and the target base station, control service information, and communication link information can refer to determining that the target I/O device needs to work in coordination with other I/O devices and is connected to the same base station with other I/O devices based on the first access situation of the target I/O device and the target base station, and then judging the round-trip time of the communication link from the 5G-MEC platform to the current I/O device and the second access situation of other I/O devices and the target base station. The length of the I/O communication cycle. If the round-trip time of the communication link is less than the communication cycle, it means that the cloud PLC deployed on the 5G-MEC platform can meet the communication business requirements, and the I/O device can be connected to the cloud PLC instance deployed on the 5G-MEC. If the round-trip time of the communication link is greater than or equal to the communication cycle, it means that the cloud PLC deployed on the 5G-MEC platform cannot meet the communication business requirements. In this case, the I/O device can be first connected to the cloud PLC deployed on the base station, and then the cloud PLC deployed on the base station can be connected to the cloud PLC deployed on the 5G-MEC platform.

In an embodiment of the present disclosure, after determining, based on the control service information, a first access status of the target I/O device and the target base station, and a second access status of other I/O devices and the target base station, the method may further include:

If the first access situation indicates that the target I/O device accesses the target base station and the second access situation indicates that other I/O devices access the target base station, the cloud PLC deployed in the base station is accessed to the target I/O device.

To connect the target I/O device to the cloud-based PLC deployed on the base station, you can point the I/O to send the IP address and open port number of the base station cloud-based PLC instance. After receiving the IP address and port number, the I/O binds them and can communicate with the cloud-based PLC instance deployed on the base station.

In an embodiment of the present disclosure, a method for determining an access relationship between a PLC of a target base station and an I/O device based on a first access status of the target I/O device and the target base station, a second access status of other I/O devices and the target base station, control service information, and communication link information may include:

If the first access condition indicates that the target I/O device is connected to the target base station, and the second access condition indicates that other I/O devices are not connected to the target base station, then compare the communication cycle between the I/O device and the PLC in the control service information with the round-trip time of the communication link from the PLC to the I/O device in the communication link information to obtain a comparison result;

If the comparison result shows that the round-trip time of the communication link is less than the communication cycle, the cloud-based PLC deployed on the 5G-MEC platform is connected to the target I/O device;

If the comparison result shows that the round-trip time of the communication link is greater than or equal to the communication cycle, the target I/O device is first connected to the cloud-based PLC deployed on the base station, and then the cloud-based PLC deployed on the base station is connected to the cloud-based PLC deployed on the 5G-MEC platform.

If the comparison result shows that the round-trip time of the communication link is less than the communication cycle, it can be said that the cloud PLC deployed on the 5G-MEC platform can meet the communication service requirements. In this case, the I/O device can be connected to the cloud PLC instance deployed on the 5G-MEC platform for communication.

To connect the target I/O device to the cloud-based PLC deployed on the 5G-MEC platform, you can point to the I/O to send the IP address and open port number of the 5G-MEC cloud-based PLC instance. After receiving the IP address and port number, the I/O will bind them and communicate with the cloud-based PLC instance deployed on the 5G-MEC platform.

If the comparison result shows that the round-trip time of the communication link is greater than or equal to the communication cycle, it may mean that the cloud PLC deployed on the 5G-MEC platform cannot meet the communication service requirements, and therefore hierarchical PLC access is required to complete the communication process.

First, connect the target I/O device to the cloud-based PLC deployed on the base station, and then connect the cloud-based PLC deployed on the base station to the cloud-based PLC deployed on the 5G-MEC platform. This can refer to a hierarchical PLC access solution. First, send the IP address and open port number of the base station cloud-based PLC instance to the I/O. After receiving, the I/O binds the IP address and port number. In this way, the target I/O device is connected to the cloud-based PLC deployed on the base station. The cloud-based PLC completes the control business communication with the I/O. Then, new ports are opened to the base station cloud-based PLC instance and the 5G-MEC cloud-based PLC instance. In this way, the cloud-based PLC deployed on the base station is connected to the cloud-based PLC deployed on the 5G-MEC platform. The cloud-based PLC deployed on the 5G-MEC platform completes the collaborative task processing between different I/Os.

In an embodiment of the present disclosure, after determining the access relationship between the PLC of the target base station and the I/O device based on the access status of the target I/O device and the target base station, the access status of other I/O devices and the target base station, control service information, and communication link information, the method may further include:

The access relationship is sent to the cloud PLC so that the cloud PLC sends the corresponding IP and open port number to the I/O device according to the access relationship. After the I/O device receives and binds the corresponding IP and open port number, it communicates with the cloud PLC.

Sending the corresponding IP and open port number to the I/O device can refer to determining the port configuration information of the I/O device to implement the configuration function between the PLC and the I/O. For example, for an I/O device accessing a cloud-based PLC instance deployed on a base station, the IP and open port number of the base station cloud-based PLC instance are sent to the I/O. After receiving the information, the I/O binds the IP and port number, and can then communicate with the cloud-based PLC instance deployed on the base station. For an I/O device accessing a cloud-based PLC instance deployed on a 5G-MEC platform, the IP and open port number of the 5G-MEC cloud-based PLC instance are sent to the I/O. After receiving the information, the I/O binds the IP and port number, and can then communicate with the cloud-based PLC instance deployed on the 5G-MEC platform. For a hierarchical PLC access solution, the IP and open port number of the base station cloud-based PLC instance are first sent to the I/O. After receiving the information, the I/O binds the IP and port number, and then new ports are opened for the base station cloud-based PLC instance and the 5G-MEC cloud-based PLC instance to communicate.

In an embodiment of the present disclosure, the method may further include:

Get network link information, including network status and I/O port information;

Determine the data deterministic transmission configuration principle for PLC control business data based on network link information, the access relationship between PLC and I/O devices, and the control business information of I/O devices;

Process business data according to the data deterministic transmission configuration principle.

The data deterministic transmission configuration principle may refer to the deterministic transmission principle of PLC control business data formulated by the deterministic transmission configuration module based on the round-trip time of the network communication link, the device access relationship and the control business parameters, including principles such as data frame aggregation and traffic shaping. Among them, determinism may refer to guarantee and reliability, that is, data is communicated and transmitted in a complete and secure manner.

In an embodiment of the present disclosure, after determining the data deterministic transmission configuration principle of PLC control service data based on network link information, the access relationship between the PLC and the I/O device, and the control service information of the I/O device, the method may further include:

Determine the data deterministic transmission parsing configuration information based on the data deterministic transmission configuration principle, the access relationship between the PLC and the I/O device, and the configuration information of the I/O device;

Data deterministic transmission and parsing configuration information may refer to the parameter information that needs to be configured for data transmission and parsing determined by the I/O control module based on the data deterministic transmission configuration principles and the configuration information of the I/O device. The parsing configuration information is a prerequisite for data parsing, so that the I/O data plane functional module can perform parsing business configuration according to the parsing configuration information and send the data to each I/O device through each data write channel.

The data write channel can refer to the data channel established between the data plane functional module and each I/O device, provided by the I/O interface management module, to ensure that data can be transmitted to the I/O device in a timely and efficient manner.

The 5G cloud-based PLC deterministic transmission method provided by the embodiment of the present disclosure can obtain configuration information by detecting the I/O device. Since the base station to which the I/O device is connected can be known through the configuration information, the first access information can be determined to obtain the target I/O device and other I/O devices. At the same time, the access situation of the target I/O device and other I/O devices to the base station can also be obtained. Then, the control business information and communication link information of the I/O device can be used to determine whether the business needs can be met. In this way, the access relationship between the PLC of the target base station and the I/O device can be determined, thereby achieving flexible allocation and routing between the PLC and the I/O devices, and solving the problem that the multi-location deployment of the 5G network cloud-based PLC cannot be met.

Determining whether the cloud-based PLC deployed on the 5G-MEC platform meets the control service requirements of the current I/O device can refer to comparing the communication link RTT from the 5G-MEC platform to the current I/O with the I/O communication cycle. If the communication link RTT from the 5G-MEC platform to the current I/O is less than the I/O communication cycle, the requirements are met; otherwise, the requirements are not met.

S204: If the requirements are met, the current I/O is connected to the cloud PLC deployed on the 5G-MEC platform. If the requirements are not met, a hierarchical PLC access solution is adopted to connect the target I/O to the cloud PLC deployed on the base station. The cloud PLC completes the control business communication with the I/O. The cloud PLC deployed on the base station is then connected to the cloud PLC deployed on the 5G-MEC platform. The cloud PLC deployed on the 5G-MEC platform completes the collaborative task processing between different I/Os.
