All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order.

The invention is described in further detail below with reference to the attached drawing figures:
referring to fig. 1 and 2, in an embodiment of the present invention, a method for synchronizing a trusted policy and a trusted state of a DCS controller in real time is provided, so that consistency and instantaneity of the trusted policy and the trusted state between a trusted management platform and the DCS controller can be effectively ensured. Specifically, the method comprises the following steps:
s1: when the trusted strategy and the trusted state of the DCS controller are changed, changing data of the trusted strategy and the trusted state of the DCS controller are obtained, and a changing trigger signal is generated.
S2: and generating a change notification file according to the trusted policy and the change data of the trusted state of the DCS controller, and storing the change notification file into a first preset directory.
S3: and acquiring the process PID number of the trusted agent process, and transmitting a change trigger signal to the trusted agent process based on the process PID number of the trusted agent process.
S4: the trusted agent process responds to the change trigger signal, moves the change notification file in the first preset directory to the processing directory of the trusted agent process, analyzes the change notification file to obtain an analysis result, and uploads the analysis result to the trusted management platform.
When the trusted policy of the DCS controller or the trusted state of a specific file, process, etc. is changed, in order to maintain the consistency of the trusted policy and the trusted state, the trusted management platform needs to be notified of the changes in real time, so that the trusted policy and the trusted state of the trusted management platform and the DCS controller maintain consistency.
According to the real-time synchronization method for the trusted strategy and the trusted state of the DCS controller, when the trusted strategy and the trusted state of the DCS controller are changed, changing data of the trusted strategy and the trusted state of the DCS controller are obtained, and a changing trigger signal is generated; and then generating a change notification file according to the trusted policy and the change data of the trusted state of the DCS controller, and storing the change notification file into a first preset directory. Meanwhile, based on the process PID number of the trusted agent process, a change trigger signal is sent to the trusted agent process, the trusted agent process responds to the change trigger signal, a change notification file in a first preset directory is moved to a processing directory of the trusted agent process, the change notification file is analyzed to obtain an analysis result, the analysis result is uploaded to a trusted management platform, and the trusted management platform updates a trusted strategy and a trusted state of a corresponding DCS controller according to the received analysis result, so that the consistency of data of the DCS controller and the trusted management platform can be maintained. By using the signal response mechanism, the trusted agent process can be ensured to process the change situation in time after receiving the change trigger signal, even if the trusted agent process cannot process the change due to some reasons, the change notification file always exists, the next time the trusted agent process receives the change trigger signal, the trusted agent process can also process the change trigger signal together, the situation of data loss can not occur, and the situation of data loss caused by the disconnection of socket connection or overlarge network load due to the use of the synchronization mechanisms such as socket communication and the like is avoided. In addition, one change notification file may include a plurality of change information, so when a plurality of changes are generated simultaneously, only one change trigger signal needs to be sent, so that frequent sending of the change trigger signal to the trusted agent process is avoided, and additional overhead is brought to the processing of the trusted agent process.
In one possible implementation manner, the generating the change notification file according to the change data of the trusted policy and the trusted status of the DCS controller, and storing the change notification file in the first preset directory includes: and packaging the change data of the trusted policy and the trusted state of the DCS controller into a file in a JSON format according to a predefined format to obtain a change notification file and storing the change notification file into a first preset directory.
In one possible implementation manner, the method for synchronizing the trusted policy and the trusted status of the DCS controller in real time further comprises: when the trusted agent process is started, a process PID (proportion integration differentiation) number of the trusted agent process is generated, and the process PID number of the trusted agent process is stored in a second preset directory. The process PID number obtaining the trusted agent process comprises the following steps: and acquiring the process PID number of the trusted agent process from the second preset directory.
In a possible implementation manner, if the trusted agent process is not started or the sending of the change trigger signal fails, the newly generated change notification file on the DCS controller will be added to the back of the existing change notification file until the trusted agent process is taken away again when the trusted agent process is started next time, so that the loss of data can be effectively avoided.
In one possible implementation, when uploading the parsing result to the trusted management platform fails: and storing the change notification file into a processing directory of the trusted agent process, and deleting the change notification file in the processing directory of the trusted agent process after the analysis result is successfully uploaded to the trusted management platform.
Specifically, if the connection between the DCS controller and the trusted management platform is interrupted, the change notification file acquired by the trusted agent process is temporarily stored under the processing directory of the trusted agent process until the DCS controller and the trusted management platform resume communication the next time, and then all the change notification files are uploaded to the trusted management platform at one time, so that the loss of data can be effectively avoided.
In one possible implementation, the DCS controller and trusted management platform maintain a communication connection through a heartbeat mechanism. Specifically, the connection is considered to be interrupted if the heartbeat is not received, which is judged by the heartbeat of the DCS controller. In addition, if the change notification file cannot be transferred to the trusted management platform, the DCS controller is local until the next connection is successful, so the change notification file is not lost.
In summary, according to the method for synchronizing the trusted policy and the trusted state of the DCS controller in real time, when the trusted agent process is started, the process PID of the trusted agent process is written into the second preset directory, when the trusted policy and the trusted state of the DCS controller are changed, the change data of the trusted policy and the trusted state of the DCS controller are packaged into the JSON format data to obtain the change notification file, the process PID of the trusted agent process is obtained from the recorded PID of the trusted agent process, then the change trigger signal is sent to the trusted agent process, after the trusted agent process receives the change trigger signal, the corresponding change notification file is analyzed, the analysis result is reported to the trusted management platform, and the trusted management platform updates the trusted policy and the trusted state according to the received analysis result, so that the consistency of the data of the DCS controller and the trusted management platform can be maintained. When a plurality of changes are generated simultaneously, all corresponding change notification files are added together, and only one change trigger signal is needed to be sent, so that extra cost caused by excessive change trigger signals to the processing of the trusted agent process is avoided.
The change of the trusted strategy and the trusted state on the DCS controller can be transmitted to the trusted management platform in real time for display and alarm through the trusted strategy and the trusted strategy synchronization mechanism, and the situation that the socket connection is disconnected or data is lost when the network load is overlarge due to the socket communication equivalent mechanism is avoided. The method can ensure that the trusted agent thread can process the change condition in time after receiving the change trigger signal, and even if the trusted agent process cannot process the change for some reasons, the change notification file always exists, and the trusted agent process can process the change trigger signal at the same time after receiving the change trigger signal at the next time, so that the data loss can not occur.
