Level1 refers to a subsystem formed by a main controller MPU, an IO module, a communication module, a power module and the like, and devices such as a Level1 layer gateway on a system network, wherein the Level1 gateway is a gateway located at a Level1 layer in a nuclear power DCS, supports algorithm configuration, and is installed and supported with device redundancy, and mainly completes the functions of protocol conversion and data communication between the DCS system and a third-party system.
The third-party systems are various in types and different in communication protocols, and besides the industrial standard protocol, the third-party systems also have a plurality of self-defined protocols. In addition, the Level1 gateways of different manufacturers have different implementation schemes, and some Level1 gateways have only one communication interface with a third party, and can only communicate with a specific third party system during operation, and adopt a specific communication protocol, if the system needs to communicate with a plurality of different third party systems, a plurality of Level1 gateway devices are usually required to be configured in the DCS system, for example: modbus gateway, UDP gateway, etc.; some Level1 gateways have more than one interface for communication with third-party, and can communicate with a plurality of different third-party systems at the same time, but such gateways need to be configured before operation, configure parameters and protocols of each communication network port, and such configuration is not changeable once the gateway device is operated, such as: the connection relation between the Level1 gateway internet access and a third party system is changed, the gateway internet access 1 is connected with a third party A, the gateway internet access 2 is connected with a third party B, if the connection between the gateway internet access 1 and the third party B is modified, the gateway internet access 2 is connected with the third party A, the Level1 gateway equipment needs to be powered on again after reconfiguration, and therefore inconvenience is brought to user operation.
In order to solve the problem, in the scheme, each physical network port of a Level1 gateway is modeled logically and uniformly, namely, a network port information structure is determined, and a network port management task is created for uniform management, namely, when each network port of the gateway needs to be reconfigured, the network port management task updates a network port information table in which relevant information of each network port is stored, so that the reconfiguration of the network port under the online condition is realized by calling the information in the network port information table, wherein the network port management task is a network port configuration system which can update a protocol entry pointer and parameters of the network port in the running process of the gateway.
Specifically, the portal configuration information is obtained, that is, what configuration needs to be performed on each portal in the Level1 gateway, for example: modifying the communication protocol of the internet access, changing the protocol parameters, changing the protocol communication point and the like.
After the configuration information is obtained, the network port information table is initialized, namely the protocol entry pointer of each network port in the network port information table is updated.
The network port information table may be a structure array or a linked list composed of network port information structures, in which the network port information structures of each network port in the Level1 gateway are stored, and the network port information structure (network _ INFO structure) includes parameters and a protocol entry pointer, as shown in fig. 2.
Wherein, the parameters in the network port information structure at least comprise: the parameters in the network port information structure are logical abstractions to the network port, and no matter whether the protocol of the network port changes, the parameter values of the network port are different along with the difference of the protocol, but the parameter types of the network port cannot change, only some protocols may not use all parameters, and the parameters are not used, but are not initialized, but the parameters support all the protocols; the protocol entry pointer in the portal information structure is a function pointer to a protocol entry function.
Therefore, when the portal information table is initialized, it is practical to initialize and update the protocol entry pointer of each portal in the portal information table, so as to update the protocol entry pointer of each portal to the protocol task entry pointer matching the specified protocol in the obtained portal configuration information.
After the protocol entry pointer of each network port in the network port information table is updated, a protocol communication task is established through the network port, and the established protocol communication task is executed. When the network port executes the communication task, the network port actually implements the execution of the protocol matched with the network port by each network port based on the protocol task entry pointer of the network port updated in the network port information table.
In the field of nuclear power DCS, when network ports carry out protocol communication tasks, each network port in a Level1 gateway can simultaneously and respectively carry out corresponding communication tasks, the communication tasks can be the same or different, the used communication protocols can be the same or different, and the network ports in the Level1 gateway are not influenced by each other.
In the scheme, an engineer station online downloading mode, namely a protocol online configuration mode, is adopted, the downloaded Level1 gateway can operate according to new configuration, the Level1 gateway is always online in the DCS system in the process, the communication with the Level2 server and the self-diagnosis function are not affected, the power is not required to be re-powered on after power failure, and the characteristic is greatly suitable for different field application scenes. The engineer station is mainly used as an off-line tool for configuration, maintenance and off-line analysis of the whole system.
In the network port configuration method disclosed in this embodiment, in the gateway operation process, network port configuration information is obtained, a network port information structure is determined, a protocol entry pointer of each network port in a network port information table is updated to a protocol task entry pointer matched with a specified protocol in the network port configuration information based on the network port configuration information, and parameters of the network port are updated according to the network port configuration information, the network port information table is at least used for storing parameters of at least one network port of a preset gateway and the protocol entry pointer, and a protocol communication task is created for each network port based on the protocol task entry pointer in the updated network port information table, so that the protocol communication task is executed through each network port. According to the scheme, in the running process of the gateway, after the network port configuration information is obtained, the protocol entry pointer of the network port and the parameters of the network port stored in the network port information table are updated, so that the protocol entry pointer and the parameters stored based on the current network port configuration information are stored in the updated network port information table, a protocol communication task can be executed based on the network port after the network port information table is updated, the communication protocol of each network port in the gateway can be reconfigured under the online condition of the gateway, the process that the gateway needs to be powered off and then powered on again when the communication protocol is updated is avoided, and the user experience is improved.
The embodiment discloses a network port configuration method, a flowchart of which is shown in fig. 3, and the method includes:
step S31, in the gateway operation process, obtaining the network port configuration information and determining the network port information structure;
step S32, updating the protocol entry pointer of each network port in the network port information table to the protocol task entry pointer matched with the specified protocol in the network port configuration information based on the network port configuration information, and updating the parameters of the network port according to the network port configuration information, wherein the network port information table is at least used for storing the parameters and the protocol entry pointer of at least one network port of the preset gateway;
step S33, traversing each network port information in the network port information table, and determining whether each network port in the network port information table is configured with a protocol;
step S34, if it is determined that the network port is configured with the protocol, creating a communication protocol task for the network port based on the protocol task entry pointer corresponding to the network port in the updated network port information table.
After initializing and updating each network port in the network port information table through the network port configuration information, traversing information of each network port in the network port information table to determine which network ports in the network port information table are configured with protocols and which network ports are not configured with protocols, wherein the network ports are configured with the protocols and indicate that the network ports configured with the protocols need to execute communication protocol tasks in the current downloading scene, and the network ports not configured with the protocols do not need to execute the communication protocol tasks in the current downloading scene.
Specifically, the determination is performed from the first portal in the portal information table, such as: determining whether the internet access 1 is configured with a protocol, and if the internet access 1 is configured with the protocol, establishing a communication task of the internet access 1; then determining whether the internet access 2 is configured with a protocol, and if the internet access 2 is configured with the protocol, establishing a communication task of the internet access 2; and determining whether the network port 3 is configured with a protocol, if the network port 3 is not configured with the protocol, directly determining whether the subsequent network port 4 is configured with the protocol without establishing a communication task for the network port 3, and ending the process until the last network port is traversed.
Further, the identification information of the internet access is sent to the protocol communication task to be executed by the internet access, so that the protocol communication task can obtain the parameters of the internet access based on the identification information.
The identification information of the network port can be a network port number, the network port number is used as an access parameter of a protocol communication task and is transmitted to the protocol communication task corresponding to the network port, and the protocol communication task can search a network port information table through the network port number so as to obtain the relevant communication parameters of the network port.
Specifically, the identification information of the internet access is set as the entry parameter of the entry function of the specified task in the internet access configuration information, wherein the protocol entry pointer is the protocol task entry pointer of the entry function of the specified protocol in the internet access configuration information.
The protocol communication task is provided with an entry function which is a main function of the protocol communication task, the main function has entry parameters, identification information of a network port, namely a network port number, is set as the entry parameters of the main function, and information of the corresponding network port in a network port information table can be found based on the entry parameters when the protocol communication task is executed, so that the protocol communication task is executed by utilizing the network port.
Further, updating the protocol entry pointer of each network port in the network port information table to the protocol task entry pointer matched with the specified protocol in the network port configuration information based on the network port configuration information, including:
when the protocol communication task of at least one network port in the preset gateway is determined to stop, the protocol entry pointer of the at least one network port in the network port information table is cleared, and when the network port configuration information is obtained, the protocol task entry pointer which is specified to be matched with the protocol in the network port configuration information is written into the network port information table.
The preset gateway, namely the Level1 gateway, can clear the network port information table as long as the protocol communication task of one network port in the Level1 gateway stops, and recover the network port resources, namely, clear the protocol entry pointer of the network port in the network port information table, so that the network port has no corresponding communication protocol. Only after the configuration information of the network port is obtained, a protocol task entry pointer matched with a protocol specified by each network port in the configuration information of the network port is written into the network port information table, namely, a new communication task is distributed to each network port in the network port information table, so that the online modification of the network port and the protocol is realized, in the process, a Level1 gateway does not need to be powered off, in the modification process of the network port and the protocol, the communication between a Level1 gateway and a Level2 server is not interrupted, and in the process, the state of the Level1 gateway can be monitored through a Level2 operator station.
The network port configuration information may be obtained by clearing and updating the protocol entry pointer of each network port only after the protocol communication task of each network port in the Level1 gateway is stopped.
In addition, it may be: when the network port configuration information is obtained, the protocol entry pointer of each network port in the network port information table is switched from the function pointer corresponding to the stopped protocol communication task to the protocol task entry pointer matched with the specified protocol in the network port configuration information.
That is, after the protocol communication task of each network port is stopped, the protocol entry pointer in the network port information table is not cleared, but when each network port needs to be reconfigured, the old protocol entry pointer is directly replaced by the new protocol entry pointer, thereby realizing the update of the network port information table.
In addition, in the scheme, different network ports are supported to simultaneously operate different protocols, and different network ports are also supported to operate the same protocol. If a new protocol is added in the gateway, only protocol codes need to be developed, a protocol main function inlet is hung in the network port information table, unified management of network port management tasks is received in a unified mode, the original framework is not affected, operation of the adding and deleting communication protocols is simple, and expandability is improved.
In the network port configuration method disclosed in this embodiment, in the gateway operation process, network port configuration information is obtained, a network port information structure is determined, a protocol entry pointer of each network port in a network port information table is updated to a protocol task entry pointer matched with a specified protocol in the network port configuration information based on the network port configuration information, and parameters of the network port are updated according to the network port configuration information, the network port information table is at least used for storing parameters of at least one network port of a preset gateway and the protocol entry pointer, and a protocol communication task is created for each network port based on the protocol task entry pointer in the updated network port information table, so that the protocol communication task is executed through each network port. According to the scheme, in the running process of the gateway, after the network port configuration information is obtained, the protocol entry pointer of the network port and the parameters of the network port stored in the network port information table are updated, so that the protocol entry pointer and the parameters stored based on the current network port configuration information are stored in the updated network port information table, a protocol communication task can be executed based on the network port after the network port information table is updated, the communication protocol of each network port in the gateway can be reconfigured under the online condition of the gateway, the process that the gateway needs to be powered off and then powered on again when the communication protocol is updated is avoided, and the user experience is improved.

After initializing and updating each network port in the network port information table through the network port configuration information, traversing information of each network port in the network port information table to determine which network ports in the network port information table are configured with protocols and which network ports are not configured with protocols, wherein the network ports are configured with the protocols and indicate that the network ports configured with the protocols need to execute communication protocol tasks in the current downloading scene, and the network ports not configured with the protocols do not need to execute the communication protocol tasks in the current downloading scene.
Specifically, the determination is performed from the first portal in the portal information table, such as: determining whether the internet access 1 is configured with a protocol, and if the internet access 1 is configured with the protocol, establishing a communication task of the internet access 1; then determining whether the internet access 2 is configured with a protocol, and if the internet access 2 is configured with the protocol, establishing a communication task of the internet access 2; and determining whether the network port 3 is configured with a protocol, if the network port 3 is not configured with the protocol, directly determining whether the subsequent network port 4 is configured with the protocol without establishing a communication task for the network port 3, and ending the process until the last network port is traversed.
Further, the identification information of the internet access is sent to the protocol communication task to be executed by the internet access, so that the protocol communication task can obtain the parameters of the internet access based on the identification information.
The identification information of the network port can be a network port number, the network port number is used as an access parameter of a protocol communication task and is transmitted to the protocol communication task corresponding to the network port, and the protocol communication task can search a network port information table through the network port number so as to obtain the relevant communication parameters of the network port.
Specifically, the identification information of the internet access is set as the entry parameter of the entry function of the specified task in the internet access configuration information, wherein the protocol entry pointer is the protocol task entry pointer of the entry function of the specified protocol in the internet access configuration information.

The preset gateway, namely the Level1 gateway, can clear the network port information table as long as the protocol communication task of one network port in the Level1 gateway stops, and recover the network port resources, namely, clear the protocol entry pointer of the network port in the network port information table, so that the network port has no corresponding communication protocol. Only after the configuration information of the network port is obtained, a protocol task entry pointer matched with a protocol specified by each network port in the configuration information of the network port is written into the network port information table, namely, a new communication task is distributed to each network port in the network port information table, so that the online modification of the network port and the protocol is realized, in the process, a Level1 gateway does not need to be powered off, in the modification process of the network port and the protocol, the communication between a Level1 gateway and a Level2 server is not interrupted, and in the process, the state of the Level1 gateway can be monitored through a Level2 operator station.
