In an industrial control system, a redundancy architecture design refers to a technology for automatically switching to standby software and hardware equipment when the software and hardware are in failure without influencing the running state of an original system. The redundancy is mainly embodied in the aspects of power supply redundancy, communication redundancy, control component redundancy (such as a controller and an I/O module) and the like, the stop operation of the equipment during operation failure can be reduced to the greatest extent, and the operation reliability of the equipment is improved.
The configuration software is general data acquisition and process monitoring software applied to industrial automation, and provides an integrated platform for development of process monitoring software of an automatic control system. The configuration software provides rich functions for the field of industrial automation monitoring, so that engineers can select and configure according to engineering requirements to construct own monitoring system, the configuration software is widely applied to various fields of machinery, automobiles, petroleum, chemical engineering, papermaking, water treatment, process control and the like, centralized monitoring on small-sized automation equipment can be completed, and monitoring on a large-scale distributed complex network can also be completed by a multi-computer system which is interconnected.
The configuration transmission method provided by the embodiment can be applied to an industrial control system with a multi-controller redundancy architecture design. Under the design of the redundant architecture of the controllers, when one controller fails, the controller can be automatically switched to the other controller, so that the acquisition, transmission and control of data are not influenced, and the accuracy and safety of the system in a fault state are ensured. In an industrial control system with a multi-redundancy controller and a multi-channel redundancy architecture, the safe and stable operation of the system is not separated from the operation and maintenance in the transmission process of configuration software.
The embodiment provides a configuration transmission method. Fig. 1 is a flowchart of a configuration transmission method according to an embodiment of the present application, and as shown in fig. 1, the flowchart includes the following steps:
step S101, a plurality of data pieces are obtained by splitting according to the current configuration object.
Considering that queuing is often needed when the current configuration objects are transmitted in sequence, if data cannot be transmitted, the whole transmission process takes a long time and even pauses. In this embodiment, the current configuration object is transmitted in the global transmission mode. Specifically, when the current configuration object is subjected to transmission operation, the current configuration object is split to obtain a plurality of data slices, and the data slices are subjected to fragment transmission. Optionally, data fragmentation may be performed according to the size of the configuration object, the channel load, and other conditions, and the size of each data fragment may be the same or different, which is not limited herein. The current configuration object may be configuration content to be transmitted in various states such as to-be-modified, to-be-compiled, to-be-downloaded, and the like.
Step S102, distributing each data slice of the current configuration object to each channel of the controller so as to enable each data slice to be transmitted to the corresponding controller in parallel through each channel; the controller includes a plurality of channels.
In this embodiment, the controller includes a plurality of channels and may be redundantly configured. The channel is a specific term of a system device with a multiple voting architecture, such as a functional safety control system, and is a basic processing unit of the multiple voting system architecture. Typically, one channel contains one CPU (core) and corresponding memory, each channel running control logic independently and working in parallel with the other channels. Generally, in a safety hybrid control system, each channel contains the same safety control application and a conventional control application, wherein the safety control application is output externally through a specific software and hardware voting mechanism, the conventional control application is generally output by a main channel, and the auxiliary channel is not output.
In the prior art, the transmission of configuration content is performed in order, and since each channel needs to be transmitted, the transmission of the next packet of data is performed only when the previous packet of data is successfully transmitted in all channels of the controller. Different from the prior art, in the embodiment, after the current configuration object is split to obtain the plurality of data pieces, each data piece of the current configuration object is distributed into each channel of the controller and is transmitted to the corresponding controller in parallel through each channel, each channel is independently transmitted and maintained in the transmission process without influencing each other, and the receiving condition of the data pieces is not verified before all data pieces are transmitted, so that the configuration data management in the transmission process is reduced, and the transmission efficiency is improved.
Step S103, after all the data pieces are transmitted, determining the receiving condition of the data pieces in the controller.
In this embodiment, the correctness of the controller reception is not checked during the transmission, and the retransmission is not performed even if the time is out, the packet is lost or the data is damaged. And after all the data pieces are transmitted, determining the receiving condition of the data pieces in the controller. Specifically, the receiving condition of the corresponding data slice can be determined through data packet verification. Optionally, the check method may be parity check, CRC check, LRC check, gray code check, sum check, xor check, and the like, which is not limited in this application.
And step S104, carrying out transmission control of the corresponding data slice according to the receiving condition of the data slice.
Specifically, the transmission state management is performed on the data slice, and the receiving condition of the data slice can be divided into four states: initial, transmitted, failed, pass. The initial state refers to a default state when the data slice is ready and is not transmitted; the transmitted state refers to a state in which the reception condition is not checked after the transmission is completed, that is, the transmitted state is identified no matter whether the controller successfully receives or not after the transmission is completed; the pass status is a status that the data slice verification is successfully received; the failure status is a status that the data piece check fails to be successfully received.
In this embodiment, the receiving condition of each data slice of the current configuration object is obtained, and transmission control of the corresponding data slice is performed according to the receiving condition of the data slice. Specifically, data reception is performed on a data slice in an initial state; judging the receiving condition of the data sheet in the transmitted state; when the receiving condition of the data slice is a failure state, distributing the corresponding data slice into each channel of the controller and sending the data slice to the corresponding controller for secondary transmission, and circulating until the transmission state is a passing state, judging that the receiving is successful; when the data piece is transmitted and the check fails for a plurality of times and the preset times are accumulated, the transmission failure can be determined. Generally, the network condition is not very poor, and the success rate of sending and receiving is high. Through the mechanism, the configuration transmission efficiency can be greatly improved, and the data transmission speed is accelerated.
As shown in fig. 2, it should be noted that, in this embodiment, after all the data pieces are transmitted, the verification process for the controller data piece receiving condition and the data piece transmission control process in step S103 and step S104 may be performed in parallel, and only the download status management is used for interaction, so that mutual waiting and interference are avoided.
In summary, according to the configuration transmission method provided in the embodiment of the present application, a plurality of data pieces are obtained by splitting according to a current configuration object; distributing each data slice of the current configuration object to each channel of the controller so that each data slice is transmitted to the corresponding controller in parallel through each channel, thereby greatly reducing configuration data management in the transmission process and improving the speed and efficiency of data transmission; the transmission control of the corresponding data slice is carried out according to the receiving condition of the data slice, so that the integrity and the safety of configuration transmission are guaranteed.
The embodiments of the present application are described and illustrated below by means of preferred embodiments.
On the basis of the foregoing embodiments, in some embodiments, splitting the current configuration object into a plurality of pieces of data includes: and splitting the current configuration object into a plurality of data slices by taking the size of 1K-4K bytes as a unit. In this embodiment, when the data slice is larger than 4K bytes, the network delay is increased, and the transmission efficiency is reduced; when the data slice is smaller than 1K bytes, the configuration content is divided into too fine sections, and packet loss and damage are easy to occur. When the current configuration object is split by taking the size of 1K-4K bytes as a unit, the data transmission efficiency is better.
As shown in fig. 3, based on the above embodiments, in some embodiments, the splitting according to the current configuration object to obtain a plurality of data slices includes:
step S1011, obtaining a current configuration object and a preamble configuration object;
step S1012, determining an incremental content based on the current configuration object and the preamble configuration object;
and S1013, splitting the incremental content to obtain a plurality of data pieces.
Specifically, the data transmission can be performed on the current configuration object by adopting an integral transmission mode; in this embodiment, data incremental transmission may also be performed based on the preamble data version of the current configuration object, i.e., the preamble configuration object. Specifically, before configuration transmission, the incremental content may be determined according to the current configuration object and the preamble configuration object, and then the incremental content is split to obtain a plurality of data pieces for transmission. That is, only the configuration portion that has not been transmitted is transmitted, and the configuration portion that has been transmitted is not transmitted.
For example, in some embodiments, the current configuration object may be divided into a plurality of configuration portions, each configuration portion being independent of the other and configured with a corresponding version number. When the configuration content is transmitted, the corresponding version serial number is updated. Before configuration transmission, according to the version serial numbers of each configuration part in the current configuration object and the preamble configuration object, the configuration part corresponding to the version serial number updating part can be determined, and the configuration part is determined as the increment content to divide the data slice. It is understood that, in other embodiments, determining the delta content based on the current configuration object and the preamble configuration object may also adopt other alternative embodiments, which is not limited in this application.
As shown in fig. 4, based on the above embodiments, in some embodiments, allocating each data slice of the current configuration object to each channel of the controller so that each data slice is transmitted to the corresponding controller in parallel through each channel includes:
step S1021, acquiring the channel number of all controllers;
step S1022, controlling each data slice of the current configuration object to be sent to the corresponding controller in parallel through each channel; and the data pieces in each channel are transmitted out of order.
In this embodiment, after the current configuration object is split into a plurality of data slices, a plurality of transmission queues are obtained. Furthermore, each transmission queue is subdivided into a plurality of channel queues according to the number of channels of all the controllers, and the channel queues are mutually opposite and transmit configuration to the corresponding channels in parallel. The different data slices in each channel are transmitted to the corresponding controllers in parallel, independent transmission maintenance is not carried out on each channel queue in the transmission process, the receiving condition of the data slices is not checked before the transmission of all the data slices is finished, and the data transmission rate is ensured.
As shown in fig. 5, on the basis of the above embodiments, in some of the embodiments, when all the data pieces are completely transmitted, determining the receiving condition of the data pieces in the controller includes:
step S1031, acquiring first verification information of the received data slice;
step S1032, matching the first check information with second check information of a local corresponding data slice of the controller;
step S1033, determining a receiving condition of the corresponding data piece according to the matching result.
In this embodiment, the current configuration object is split to obtain a plurality of data slices, and first check information is added before the data slices are packed and transmitted. After the controller receives the data slice, acquiring the receiving condition of the data slice, and acquiring first check information of the data slice and writing the first check information into the data slice with the receiving condition of the data slice being initial or failed as transmitted; and judging whether the first check information in the data packet is consistent with the second check information of the local corresponding data piece of the controller or not for the data piece of which the receiving condition is transmitted, further determining the receiving condition of the corresponding data piece, and updating the transmission state of the corresponding data piece. And when the first check information is not matched with the second check information, the receiving condition of the corresponding data slice is passed, and when the receiving condition of the corresponding data slice is failed, the receiving condition of the transmitted data slice is continuously checked. The first check information and the second check information may be check codes obtained by performing check calculation on the data slice based on a preset check algorithm. For example, the preset verification Algorithm may be an MD5 Message Digest Algorithm (MD5 Message-Digest Algorithm), and each piece of data obtained by splitting the current configuration object may be calculated to generate a unique MD5 value, and is not easily tampered, so that the verification accuracy is improved.
As shown in fig. 6, on the basis of the above embodiments, in some embodiments, after performing transmission control on a corresponding data slice according to a receiving condition of the data slice, the method further includes:
step S105, performing inter-packet check on each data slice of the current configuration object.
Illustratively, after a current configuration object is split into a plurality of data pieces, at least first check information, inter-packet check information, data packet length information and the like need to be added when the data pieces are packed, after each data piece is sent, a controller terminal analyzes the data pieces to obtain each data piece, inter-packet check is performed on each data piece of the current configuration object, disorder is avoided, and meanwhile, each received data piece is packed to form a complete data packet.
It should be noted that the steps illustrated in the above-described flow diagrams or in the flow diagrams of the figures may be performed in a computer system, such as a set of computer-executable instructions, and that, although a logical order is illustrated in the flow diagrams, in some cases, the steps illustrated or described may be performed in an order different than here.
