Description

Technical Field

[0001] The present invention relates to the technical field of data monitoring, and in particular to an intelligent monitoring system for data integrity of a photovoltaic power station. Background Art

[0002] With the continuous advancement and widespread promotion of photovoltaic power station technology, the traditional monitoring system based on secondary cable hard connection is gradually being replaced by a new monitoring system based on networked data information transmission. In this transformation, intelligent monitoring of photovoltaic power station data integrity has become a key link to ensure data accuracy and security. At present, the network architecture of photovoltaic power stations is logically divided into station control layer, interval layer and process layer, and physically simplified to a two-layer layout of station control layer and process layer.

[0003] At present, the business message transmission in photovoltaic power stations is still in plain text, and the communication system within the station has not yet established a complete network attack protection and monitoring system. Especially in the intelligent monitoring system of photovoltaic power station data integrity, the security and integrity of data are even more important. For this reason, we propose an intelligent monitoring system for photovoltaic power station data integrity. Summary of the invention

[0004] The object of the present invention is to provide an intelligent monitoring system for data integrity of a photovoltaic power station.

[0005] In order to solve the problems raised in the above background technology, the present invention provides the following technical solutions: an intelligent monitoring system for data integrity of a photovoltaic power station, comprising a data acquisition module, the data acquisition module is used to collect data information of the photovoltaic power station and generate monitoring data, and also comprises an SCD matching module, a multi-level security monitoring module, a dynamic strategy configuration module, a code conversion module, an integrity matching module, an anomaly extraction module and a real-time response module;

[0006] The SCD matching module extracts the SCD configuration file information and security requirement information, sets the security monitoring rules according to the SCD configuration file information and security requirement information, and obtains the data security monitoring rule configuration file, the security monitoring policy configuration file, and the switch forwarding configuration file;

[0007] The multi-level security monitoring module performs security monitoring of monitoring data through two levels: security monitoring equipment and photovoltaic power station network switches. The security monitoring equipment is responsible for real-time monitoring of business data messages on the network, while the photovoltaic power station network switches are responsible for monitoring network access equipment conditions, physical link status and data flow information;

[0008] The dynamic policy configuration module regenerates the data security monitoring rule configuration file, security monitoring policy configuration file and switch forwarding configuration file according to the changes in the SCD configuration file information and security requirement information, making the generated configuration files more convenient to adjust and update them in real time;

[0009] The code conversion module extracts the monitoring data and splits the monitoring data into individual information, then names the individual information and generates code data. When the code data is generated for the first time, the code data generated for the first time will be converted into the original code information library. When the monitoring data is split again to generate code data, it will be included as the verification code information.

[0010] The integrity matching module extracts the information of the original code information base and the verification code information, verifies the integrity of the verification code information using the original code information base, and generates verification process information;

[0011] The abnormal extraction module extracts the code data generated for the first time, verifies its integrity, generates verification information, and then marks the verification information as verification basic information. At the same time, the deviation unit is set. The user adjusts the deviation range of the verification basic information through the deviation unit, and then extracts the verification process information, analyzes the deviation range between the verification process information and the verification basic information, and generates abnormal verification information;

[0012] The real-time response module receives and processes the non-abnormal verification information from the security monitoring equipment, the photovoltaic power station network switch and the abnormal verification information in real time, and then displays the alarm and records the information, and handles the abnormal messages, network traffic and abnormal verification information accordingly according to the security monitoring strategy.

[0013] As a further solution of the present invention: after extracting the SCD configuration file information and security requirement information, the multi-level security monitoring module will send the information of the data security monitoring rule configuration file and the security monitoring policy configuration file to the security monitoring device, and then send the information of the security monitoring policy configuration file and the switch forwarding configuration file to the photovoltaic power station network switch.

[0014] As a further solution of the present invention: after the dynamic policy configuration module updates the configuration file in real time, it will perform security monitoring on it, so that the security monitoring device monitors the business data message information on the network in real time according to the data security monitoring rule configuration file information, and monitors and processes the data messages and reports non-abnormal verification information according to the security monitoring policy, and the photovoltaic power station network switch monitors the network access device status, physical link status and data flow information in real time according to the data security monitoring rule configuration file information and the switch forwarding configuration file information, and monitors and processes the data messages and reports non-abnormal verification information according to the data security monitoring rule configuration file information.

[0015] As a further solution of the present invention: when the code conversion module splits the monitoring data, it will sort the individual information according to the splitting order to obtain a splitting sorting table. When the monitoring data is split again, it will extract the record order of the individual information in the splitting sorting table, generate standard sequence information, sort the monitoring data split again according to the standard sequence information, and mark more than one identical information with different labels.

[0016] As a further solution of the present invention: the standard sequence information is B1, B2, B3, ..., B X , suppose the monitoring data that is split into individual information again is J1, J2, J3, ..., J Y , where X and Y are unknown numbers. When sorting the split monitoring data again, from J1, J2, J3, ..., J Y Match the same single information as B1, and establish a verification sorting table;

[0017] When J1, J2, J3, ..., J Y When there is a single piece of information that is the same as B1 in the verification sort table, it will be extracted, and then the extracted single piece of information will be placed in the same order as B1 in the verification sort table, and then start from J1, J2, J3, ..., J Y Matches the same single information as B2;

[0018] When J1, J2, J3, ..., J Y When there is no single information identical to that of B1 in the verification sort table, the sorting identical to that of B1 in the verification sort table will be marked as zero;

[0019] According to the above method, B1, B2, B3, ..., B X to make a match.

[0020] As a further solution of the present invention: when the integrity matching module verifies the integrity of the verification code information, the original code information library information is set as D S , let the verification code information be Y D ;

[0021] when And Y D ∩D S =D S When the verification code information is complete, it is determined that there is no new information in the verification code information;

[0022] when And Y D ∩D S ≠D SWhen the verification code information is complete, it is determined that the verification code information contains new information;

[0023] when And Y D ∪D S =D S When the verification code information is not complete, it is determined that there is no new information in the verification code information;

[0024] when And Y D ∪D S ≠D S When the verification code information is incomplete, it is determined that there is new information in the verification code information.

[0025] As a further solution of the present invention: in the integrity matching module, when there is new information in the verification code information, the new information in the verification code information will be extracted, converted into code data, and added to the original code information library.

[0026] As a further solution of the present invention: the abnormal extraction module analyzes the verification process information and the verification

[0027] Let the deviation unit information be P 偏差 ;

[0028] When Y 过程 ∈(Y 基础 -P 偏差 )-(Y 基础 +P 偏差 ), it is determined that there is no abnormality in the verification process information. At this time, the average information of the verification basic information and the verification process information is calculated and used as the new verification basic information;

[0029] When Y 过程 <Y 基础 -P 偏差 and Y 过程 >Y 基础 +P 偏差 When the verification process information is abnormal, it is determined that there is an abnormality and the abnormality information is extracted.

[0030] As a further solution of the present invention: the real-time response module will respond to the received non-abnormal verification information and abnormal verification information, and display and record the alarms, formulate security monitoring policy instructions based on the non-abnormal verification information and abnormal verification information, execute security monitoring policy actions on the specified abnormal message data flow and abnormal verification information, and update the SCD configuration file information, data security monitoring rule configuration file, security monitoring policy configuration file and switch forwarding configuration file in real time.
