The embodiment discloses a network port configuration method, a flow chart of which is shown in fig. 3, comprising the following steps:
step S31, in the running process of the gateway, network port configuration information is obtained, and a network port information structure is determined;
Step S32, updating a protocol entry pointer of each network port in the network port information table into a protocol task entry pointer matched with a protocol specified in the network port configuration information based on the network port configuration information, and updating parameters of the network port according to the network port configuration information, wherein the network port information table is at least used for storing at least one network port parameter and protocol entry pointer of a 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 the network port is determined to be configured with the protocol, a communication protocol task is created for the network port based on a 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 the information of each network port in the network port information table is needed 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 protocols to indicate that the network ports configured with protocols need to execute communication protocol tasks in the current downloading scene, and the network ports not configured with protocols do not need to execute communication protocol tasks in the current downloading scene.
Specifically, the judgment is performed from the first portal in the portal information table, for example: determining whether the network port 1 is configured with a protocol, if the network port 1 is configured with the protocol, creating a communication task of the network port 1; then determining whether the network port 2 is configured with a protocol, if the network port 2 is configured with the protocol, creating a communication task of the network port 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 creating a communication task for the network port 3, and ending when the last network port is traversed.
Further, the identification information of the network port is sent to a protocol communication task to be executed by the network port, so that the protocol communication task can obtain parameters of the network port based on the identification information.
The network port identification information may be a network port number, the network port number is used as an input parameter of a protocol communication task to be transmitted to a protocol communication task corresponding to the network port, and the protocol communication task can search the network port information table through the network port number, so that relevant communication parameters of the network port are obtained.
Specifically, the identification information of the network port is set as an entry of an entry function of a designated task in the network port configuration information, wherein the protocol entry pointer is a protocol task entry pointer of the entry function of the designated protocol in the network port configuration information.
The protocol communication task is provided with an entry function, the entry function is a main function of the protocol communication task, the main function is provided with an entry parameter, the identification information of the network port, namely the network port number, is set as the entry parameter of the main function, and when the protocol communication task is executed, the information of the corresponding network port in the network port information table can be searched based on the entry parameter, so that the execution of the protocol communication task is realized by utilizing the network port.
Further, updating the protocol entry pointer of each network port in the network port information table to a protocol task entry pointer matched with a protocol specified in the network port configuration information based on the network port configuration information, including:
When determining that the protocol communication task of at least one network port in the preset gateway stops, clearing a protocol entry pointer of the at least one network port in the network port information table, and writing the protocol task entry pointer matched with the specified protocol in the network port configuration information into the network port information table when obtaining the network port configuration information.
The gateway is preset, namely the Level1 gateway, and the network port information table can be cleaned as long as the protocol communication task of one network port in the Level1 gateway is stopped, and network port resources are recovered, namely the protocol entry pointer of the network port in the network port information table is cleaned, so that the network port does not have a corresponding communication protocol. Only after the configuration information of the network port is obtained, a protocol task entry pointer matched with a protocol appointed by each network port in the network port configuration information is written into the network port information table, namely, a new communication task is allocated for each network port in the network port information table, so that online modification of the network port and the protocol is realized, in the process, the Level1 gateway does not need to be powered off, in the modification process of the network port and the protocol, the communication between the Level1 gateway and the Level2 server is not interrupted, and the state of the Level1 gateway can be monitored through a Level2 operator station in the process.
The obtaining of the network port configuration information may be that after the protocol communication tasks of each network port in the Level1 gateway are stopped, the protocol entry pointer of each network port can be cleared and updated.
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 protocol specified 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 the old protocol entry pointer is directly replaced by the new protocol entry pointer when the network ports are required to be reconfigured, so that the network port information table is updated.
In addition, in the scheme, different network ports are supported to operate different protocols simultaneously, and different network ports are also supported to operate the same protocol. If a new protocol is to be added in the gateway, only a protocol code needs to be developed, and a protocol main function entry is hung in a network port information table to uniformly accept the uniform management of network port management tasks, so that the original architecture is not influenced, the operation of adding and deleting communication protocols is simple, and the expandability is improved.
In the network port configuration method disclosed by the embodiment, network port configuration information is obtained in the running process of a gateway, a network port information structure is determined, a protocol entry pointer of each network port in a network port information table is updated to be a protocol task entry pointer matched with a protocol specified in the network port configuration information based on the network port configuration information, 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 and the protocol entry pointer of at least one network port of a preset gateway, and protocol communication tasks are created for each network port based on the updated protocol task entry pointer in the network port information table so as to execute the protocol communication tasks through each network port. According to the method and the device, after the network port configuration information is obtained in the gateway operation process, 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 updated network port information table stores the protocol entry pointer and the parameters stored based on the current network port configuration information, the protocol communication task can be conveniently 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 condition that the gateway is online, the process that the network is turned off and the network is electrified again when the communication protocol is updated is avoided, and the user experience is improved.

Further, the creation unit is specifically configured to: 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; if the network port is determined to be configured with the protocol, a communication protocol task is established for the network port based on a 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 the information of each network port in the network port information table is needed 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 protocols to indicate that the network ports configured with protocols need to execute communication protocol tasks in the current downloading scene, and the network ports not configured with protocols do not need to execute communication protocol tasks in the current downloading scene.
Specifically, the judgment is performed from the first portal in the portal information table, for example: determining whether the network port 1 is configured with a protocol, if the network port 1 is configured with the protocol, creating a communication task of the network port 1; then determining whether the network port 2 is configured with a protocol, if the network port 2 is configured with the protocol, creating a communication task of the network port 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 creating a communication task for the network port 3, and ending when the last network port is traversed.
Further, the identification information of the network port is sent to a protocol communication task to be executed by the network port, so that the protocol communication task can obtain parameters of the network port based on the identification information.
The network port identification information may be a network port number, the network port number is used as an input parameter of a protocol communication task to be transmitted to a protocol communication task corresponding to the network port, and the protocol communication task can search the network port information table through the network port number, so that relevant communication parameters of the network port are obtained.
Specifically, the identification information of the network port is set as an entry of an entry function of a designated task in the network port configuration information, wherein the protocol entry pointer is a protocol task entry pointer of the entry function of the designated protocol in the network port configuration information.
The protocol communication task is provided with an entry function, the entry function is a main function of the protocol communication task, the main function is provided with an entry parameter, the identification information of the network port, namely the network port number, is set as the entry parameter of the main function, and when the protocol communication task is executed, the information of the corresponding network port in the network port information table can be searched based on the entry parameter, so that the execution of the protocol communication task is realized by utilizing the network port.
Further, updating the protocol entry pointer of each network port in the network port information table to a protocol task entry pointer matched with a protocol specified in the network port configuration information based on the network port configuration information, including:
When determining that the protocol communication task of at least one network port in the preset gateway stops, clearing a protocol entry pointer of the at least one network port in the network port information table, and writing the protocol task entry pointer matched with the specified protocol in the network port configuration information into the network port information table when obtaining the network port configuration information.
The gateway is preset, namely the Level1 gateway, and the network port information table can be cleaned as long as the protocol communication task of one network port in the Level1 gateway is stopped, and network port resources are recovered, namely the protocol entry pointer of the network port in the network port information table is cleaned, so that the network port does not have a corresponding communication protocol. Only after the configuration information of the network port is obtained, a protocol task entry pointer matched with a protocol appointed by each network port in the network port configuration information is written into the network port information table, namely, a new communication task is allocated for each network port in the network port information table, so that online modification of the network port and the protocol is realized, in the process, the Level1 gateway does not need to be powered off, in the modification process of the network port and the protocol, the communication between the Level1 gateway and the Level2 server is not interrupted, and the state of the Level1 gateway can be monitored through a Level2 operator station in the process.
The obtaining of the network port configuration information may be that after the protocol communication tasks of each network port in the Level1 gateway are stopped, the protocol entry pointer of each network port can be cleared and updated.
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 protocol specified 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 the old protocol entry pointer is directly replaced by the new protocol entry pointer when the network ports are required to be reconfigured, so that the network port information table is updated.
In addition, in the scheme, different network ports are supported to operate different protocols simultaneously, and different network ports are also supported to operate the same protocol. If a new protocol is to be added in the gateway, only a protocol code needs to be developed, and a protocol main function entry is hung in a network port information table to uniformly accept the uniform management of network port management tasks, so that the original architecture is not influenced, the operation of adding and deleting communication protocols is simple, and the expandability is improved.
