The following detailed description of embodiments of the invention refers to the accompanying drawings.
Referring to fig. 1, fig. 1 is a schematic flow chart of an intelligent networking method for photovoltaic panel data acquisition equipment according to an embodiment of the present invention, where the intelligent networking method for photovoltaic panel data acquisition equipment specifically includes:
step S101, a networking request of the data acquisition equipment of the photovoltaic panel to be determined is obtained.
Specifically, the networking device acquires a networking request of the photovoltaic panel data acquisition device to be identified (referred to as a networking request of the pending photovoltaic panel data acquisition device), wherein the networking request of the pending photovoltaic panel data acquisition device may also be referred to as a request (or an indication), and in the detection process of the networking request of the pending photovoltaic panel data acquisition device, the networking request of the pending photovoltaic panel data acquisition device is still sent to the networking device from the pending photovoltaic panel data acquisition device.
Or the networking equipment is connected in series between the pending photovoltaic panel data acquisition equipment and the networking equipment, and in this case, the networking equipment can forward the networking request of the pending photovoltaic panel data acquisition equipment to the networking equipment only if the networking equipment detects the networking request of the pending photovoltaic panel data acquisition equipment. The advantage of the series connection mode is that the detection result has no hysteresis, and the networking device has no influence, because the networking device directly discards the networking request of the photovoltaic panel data acquisition device when recognizing the networking request of the photovoltaic panel data acquisition device with low security level, and the networking device does not receive the networking request of the photovoltaic panel data acquisition device with low security level at all.
Step S102, generating networking safety vectors of networking requests of the data acquisition equipment of the undetermined photovoltaic panel, wherein the networking safety vectors comprise undetermined networking source safety vectors and undetermined networking type safety vectors.
Specifically, the networking equipment generates a networking source safety vector (called as an undetermined networking source safety vector) of the networking request of the undetermined photovoltaic panel data acquisition equipment and a networking type safety vector (called as an undetermined networking type safety vector) of the networking request of the undetermined photovoltaic panel data acquisition equipment, and vectorizes the determined undetermined networking source safety vector and the undetermined networking type safety vector to form the networking safety vector of the networking request of the undetermined photovoltaic panel data acquisition equipment.
Firstly, how to extract the undetermined networking source safety vector of the networking request of the undetermined photovoltaic panel data acquisition equipment is explained as follows:
because the networking mode can be contained in the networking request of the pending photovoltaic panel data acquisition equipment, the networking equipment can directly acquire the networking mode of the networking request of the pending photovoltaic panel data acquisition equipment, and the networking equipment extracts the equipment identifier of the photovoltaic panel data acquisition equipment sending the request from the networking request of the pending photovoltaic panel data acquisition equipment, wherein the equipment identifier can comprise: the type of operating system of the photovoltaic panel data acquisition device, and the like.
The networking equipment acquires a networking relay cluster for sending a networking request of the pending photovoltaic panel data acquisition equipment, wherein the networking relay cluster can be divided into a plurality of relay equipment identifications, the plurality of relay equipment identifications are respectively a first area networking relay cluster and a second area networking relay cluster, and the networking equipment respectively acquires the safety weight of the first area networking relay cluster of the pending photovoltaic panel data acquisition equipment networking request in a safety relay equipment identification group and acquires the safety weight (both referred to as relay safety weight) of the second area networking relay cluster in the safety relay equipment identification group. The safety relay equipment identification group comprises a first area networking relay cluster set and a second area networking relay cluster set, and the relay safety weight can be known to be the safety weight of the first area networking relay cluster requested by the data acquisition equipment of the undetermined photovoltaic panel in the first area networking relay cluster set and the safety weight of the second area networking relay cluster requested by the data acquisition equipment of the undetermined photovoltaic panel in the second area networking relay cluster set.
And the networking equipment takes the obtained networking mode, equipment identification and 2 relay safety weights as a safety vector of a to-be-determined networking source of a networking request of the to-be-determined photovoltaic panel data acquisition equipment.
The following explains how to extract the undetermined networking type security vector networking equipment of the networking request of the undetermined photovoltaic panel data acquisition equipment to extract the networking type parameter (called a target networking type parameter) from the networking request of the undetermined photovoltaic panel data acquisition equipment, wherein the networking request of the photovoltaic panel data acquisition equipment comprises a network address, a broadcast address and an equipment address, and the address can be the networking type parameter in the invention. The networking equipment splits the target networking type parameter to obtain a plurality of fields (called a special line networking field set). And searching the special line networking type identifier belonging to the special line networking field set from the special line networking type identifier library.
The networking equipment can integrally regard the networking request of the data acquisition equipment of the photovoltaic panel to be determined as a character string, split the character string to obtain a plurality of fields (called standard industrial networking field sets), and search the standard industrial networking type identifiers belonging to the standard industrial networking field sets from a standard industrial networking type identifier library.
The networking equipment vectorizes the searched private networking type identifier and the searched standard industrial networking type identifier into a networking type identifier, and the private networking type identifier library and the standard industrial networking type identifier library both belong to a networking type identifier set.
The special line networking type identification library is generated after special line networking related parameters of networking type parameters in networking requests of a plurality of successfully networked photovoltaic panel data acquisition devices are extracted, and the standard industrial networking type identification library is generated after special line networking related parameters of networking requests of a plurality of successfully networked photovoltaic panel data acquisition devices corresponding to a plurality of standard industrial networking protocols are extracted.
The networking equipment calls a photovoltaic panel data acquisition equipment vector type division model to determine a photovoltaic panel data acquisition equipment vector (called as an equipment type vector of the pending photovoltaic panel data acquisition equipment) of the photovoltaic panel data acquisition equipment for sending the networking request of the pending photovoltaic panel data acquisition equipment, the photovoltaic panel data acquisition equipment vector can be used as a unique identity and used for identifying the photovoltaic panel data acquisition equipment at the bottom layer and an application program at the networking equipment end, and the realization of judging the bottom layer through the superficial identification factors such as character strings of 'id' and 'IP' is avoided.
The networking device may connect the private networking type identifier in the networking type identifiers by "-", calculate a HASH value of the connected character string, and use the HASH value as a networking type vector of the private networking type identifier. Similarly, the networking device may connect the standard industrial networking type identifier in the networking type identifiers by using "-", calculate a HASH value of the connected character string, and use the HASH value as a networking type vector of the standard industrial networking type identifier.
The networking equipment can vectorize the networking type vector identified by the private line networking type, the networking type vector identified by the standard industrial networking type and the equipment type vector of the undetermined photovoltaic panel data acquisition equipment to form a networking type safety vector (called as an undetermined networking type safety vector) requested by the networking of the undetermined photovoltaic panel data acquisition equipment.
Therefore, the undetermined networking source safety vector and the undetermined networking type safety vector of the networking request of the undetermined photovoltaic panel data acquisition equipment are determined.
The networking vector is constructed from multiple dimensions such as photovoltaic panel data acquisition equipment and protocol types. The security vector of the source of the pending networking may include a networking mode, an operating system type and a request packet header (the operating system type and the request packet header may also be vectorized as a device identifier), where the networking mode may be detected based on link protocol identification, the operating system type may be detected based on operating system version identification difference identification, and a field attribute risk coefficient may be determined based on the request packet header subsequently, where the field attribute risk coefficient is detected based on application layer machine identification. The special line networking vector can correspond to the networking type vector of the special line networking type identifier in the invention, and the standard industrial networking load sequence can correspond to the networking type vector of the standard industrial networking type identifier in the invention. The photovoltaic panel data acquisition device vector aggregation model can be used for constructing a device vector library and identifying a photovoltaic panel data acquisition device vector of any photovoltaic panel data acquisition device. The special line networking vector aggregation model can be used for constructing a special line networking type identification library and a special line networking preset networking source set, and the standard industrial networking load sequence aggregation model can be used for constructing a standard industrial networking type identification library and a standard industrial networking preset networking source set.
Step S103, determining the networking request networking safety level of the data acquisition equipment of the undetermined photovoltaic panel according to the safety weight of the safety vector of the undetermined networking type in a preset networking source set and the safety vector of the source of the undetermined networking; the preset networking source set comprises networking type safety vectors of successful networking requested by a plurality of successfully networked photovoltaic panel data acquisition devices.
Specifically, as can be seen from the foregoing, the to-be-determined networking type safety vector includes a networking type vector of a private networking type identifier, an equipment type vector of the to-be-determined photovoltaic panel data acquisition equipment, and a networking type vector of a standard industrial networking type identifier, the networking equipment calculates a safety weight (referred to as a private networking vector safety weight) of the networking type vector of the private networking type identifier (the networking type vector of the private networking type identifier may also be referred to as a private networking vector of a networking request of the to-be-determined photovoltaic panel data acquisition equipment) in a private networking preset networking source set, and determines a private networking risk coefficient according to the private networking vector safety weight. Certainly, the higher the safety weight of the private line networking vector is, the higher the private line networking risk coefficient is, and the private line networking preset networking source set comprises the private line networking vectors requested by the networking of the photovoltaic panel data acquisition equipment which has been successfully networked.
The networking equipment calculates the safety weight (called type vector safety weight) of the equipment type vector of the to-be-determined photovoltaic panel data acquisition equipment in the equipment type source set, and determines the type risk coefficient according to the type vector safety weight. Of course, the higher the safety weight of the type vector, the higher the type risk coefficient, and the device type source set includes the photovoltaic panel data acquisition device vector requested by the networking of a plurality of successfully networked photovoltaic panel data acquisition devices.
The networking equipment calculates the security weight (referred to as standard industrial networking vector security weight) of a networking type vector of a standard industrial networking type identifier (the networking type vector of the standard industrial networking type identifier can also be referred to as standard industrial networking vector of a networking request of the data acquisition equipment of the undetermined photovoltaic panel) in a standard industrial networking preset networking source set, and determines a standard industrial networking risk coefficient according to the standard industrial networking vector security weight. Certainly, the higher the safety weight of the standard industrial networking vector is, the higher the standard industrial networking risk coefficient is, and the standard industrial networking preset networking source set comprises the standard industrial networking vectors of the networking requests of the photovoltaic panel data acquisition devices which are successfully networked and correspond to a plurality of standard industrial networking protocols. Furthermore, when the standard industrial networking risk coefficient is determined, not only the standard industrial networking vector safety weight needs to be referred, but also which standard industrial networking protocol the standard industrial networking vector requested by the to-be-determined photovoltaic panel data acquisition equipment for networking corresponds to can be further determined, and the standard industrial networking risk coefficient is determined together according to the determined standard industrial networking protocol and the standard industrial networking vector safety weight. The plurality of standard industrial networking protocols comprise 3 standard industrial networking protocols which are respectively as follows: a step of collecting target information by stepping points; establishing a site stage; a lateral movement phase.
And the networking equipment adds the special line networking risk coefficient, the type risk coefficient and the standard industrial networking risk coefficient into a networking type risk coefficient.
As can be seen from the foregoing, the security vector of the source of the pending networking includes: networking mode, equipment identification and relay security weight. The networking equipment respectively determines risk coefficients (called networking mode risk coefficients) corresponding to link protocols similar to networking requests of the pending photovoltaic panel data acquisition equipment, determines risk coefficients (called equipment identity risk coefficients) corresponding to equipment identifications and determines risk coefficients (called relay identity risk coefficients) corresponding to safety weights, wherein the networking equipment determines the risk coefficients based on a preset rule mode. The networking equipment can add the networking mode risk coefficient, the equipment identity risk coefficient and the relay identity risk coefficient into a networking source risk coefficient.
How to determine the link protocol to determine the corresponding networking mode risk coefficient is first described below:
the networking equipment determines a value corresponding to the networking mode based on a preset rule, and the value is used as a networking mode risk coefficient corresponding to the networking mode. For example, the preset rule is: the http protocol type corresponds to a value of 5, the ftp protocol type corresponds to a value of 10, the smtp protocol type corresponds to a value of 15. Assuming that the networking mode of the networking request of the undetermined photovoltaic panel data acquisition equipment is of an http protocol type, the networking mode risk coefficient of the networking request of the undetermined photovoltaic panel data acquisition equipment may be 5.
How to determine the corresponding equipment identity risk coefficient according to the equipment identifier is described as follows:
as can be seen from the foregoing, the device identifier may include an operating system type of the photovoltaic panel data acquisition device and a request packet header, and the networking device determines a value corresponding to the operating system type based on a preset rule, and uses the value as an operating system risk coefficient corresponding to the operating system type. For example, the preset rule is: the windows operating system type corresponds to a value of 5, the linux operating system type corresponds to a value of 10, and the unix operating system type corresponds to a value of 15. Assuming that the operating system type of the photovoltaic panel data collection device sending the networking request of the pending photovoltaic panel data collection device is a windows operating system type, the risk coefficient of the operating system of the networking request of the pending photovoltaic panel data collection device may be 10.
The networking equipment detects whether a request message header in the equipment identifier is empty, and if the request message header in the equipment identifier is empty, the attribute of the request message header can be marked as black; if not, further detecting whether the request message header is generated by a common automation tool, if so, marking the attribute of the request message header as A; if not, further extracting a header field sequence of the request message header, if the header field sequence is a common browser request header, marking an attribute of the request message header as B, if the header field sequence is an automation tool request header, marking the attribute of the request message header as C, and if the header field sequence is neither the common browser request header nor the automation tool request header, marking the attribute of the request message header as A. And the networking equipment determines a field attribute risk coefficient according to the attribute of the request message header, wherein the field attribute risk coefficient of the request message header marked as A is greater than the field attribute risk coefficient of the request message header marked as C is greater than the field attribute risk coefficient of the request message header marked as B.
And the networking equipment adds the operating system risk coefficient and the field attribute risk coefficient determined in the previous step into an equipment identity risk coefficient.
How to determine the relay identity risk coefficient corresponding to the relay security weight is further described below:
as can be seen from the foregoing, the number of the relay security weights is 2, and the relay security weights are respectively the relay security weight of the first area networking relay cluster in the first area networking relay cluster set requested by the pending photovoltaic panel data acquisition device, and the relay security weight of the second area networking relay cluster in the second area networking relay cluster set requested by the pending photovoltaic panel data acquisition device. The networking equipment respectively determines a first area risk coefficient corresponding to the relay safety weight of the first area networking relay cluster and a second area risk coefficient corresponding to the relay safety weight of the second area networking relay cluster based on a preset rule. And taking the sum of the first area risk coefficient and the second area risk coefficient as a relay identity risk coefficient.
Optionally, in addition to determining the relay identity risk coefficient by using the foregoing method, the networking device may also determine the relay identity risk coefficient by using the following method: the networking equipment adds the relay safety weight of the first area networking relay cluster and the relay safety weight of the second area networking relay cluster into a target relay safety weight, and determines a relay identity risk coefficient corresponding to the target relay safety weight based on a preset rule.
The networking equipment acquires a networking type risk coefficient and a networking source risk coefficient, the networking equipment can add the networking type risk coefficient and the networking source risk coefficient into a comprehensive networking risk coefficient, and if the comprehensive networking risk coefficient is larger than a preset first preset risk coefficient threshold, the networking equipment determines that the networking request security level of the pending photovoltaic panel data acquisition equipment is a low security level;
otherwise, if the comprehensive networking risk coefficient is not larger than a preset first preset risk coefficient threshold, determining that the networking request security level of the data acquisition equipment of the photovoltaic panel to be determined is a normal type.
And step S104, if the networking safety level of the networking request of the to-be-determined photovoltaic panel data acquisition equipment is a low safety level, the networking circuit where the networking request of the to-be-determined photovoltaic panel data acquisition equipment is located is forbidden.
Specifically, if the networking security level of the networking request of the photovoltaic panel data acquisition equipment to be determined is a normal type and the networking equipment are in a parallel relation, the networking equipment can not process the networking request of the photovoltaic panel data acquisition equipment to be determined;
if the networking security level of the networking request of the undetermined photovoltaic panel data acquisition equipment is a normal type and the networking equipment are in a series relation, the networking equipment can forward the networking request of the undetermined photovoltaic panel data acquisition equipment to the networking equipment, namely the networking equipment indicates that the networking request of the undetermined photovoltaic panel data acquisition equipment does not have any security threat, and the networking equipment can respond to the service request of the networking request of the undetermined photovoltaic panel data acquisition equipment.
If the networking security level of the networking request of the to-be-determined photovoltaic panel data acquisition equipment is a low security level and the networking equipment are in a parallel relation, the networking equipment respectively sends a blocking message (namely a RESET message) to the photovoltaic panel data acquisition equipment and the networking equipment, wherein the RESET message has the function of blocking a networking line (the networking line is also called as tcp connection) between the photovoltaic panel data acquisition equipment and the networking equipment so that the networking equipment can release connection resources, and the released connection resources can be used for responding to the requests of other networking initiators to avoid the networking equipment from being in a down state. In this case, the networking device may receive a networking request of the pending photovoltaic panel data acquisition device, but once the networking device receives the blocking message, the networking device does not need to respond to a service request of the networking request of the pending photovoltaic panel data acquisition device; or, because the time consumed by the invention for detecting the networking request security level of the pending photovoltaic panel data acquisition equipment is short enough, when the networking request of the pending photovoltaic panel data acquisition equipment does not reach the networking equipment, the networking equipment detects the networking request security level of the pending photovoltaic panel data acquisition equipment, if the type is a low security level, the networking circuit between the photovoltaic panel data acquisition equipment and the networking equipment is directly sealed, namely, the networking circuit is sealed before the networking equipment does not receive the networking request of the pending photovoltaic panel data acquisition equipment, so the networking equipment does not receive the networking request of the pending photovoltaic panel data acquisition equipment.
If the networking security level of the networking request of the undetermined photovoltaic panel data acquisition equipment is a low security level and the networking equipment are in a series relation, the networking equipment discards the networking request of the undetermined photovoltaic panel data acquisition equipment and respectively sends a blocking message (namely a RESET message) to the photovoltaic panel data acquisition equipment and the networking equipment, wherein the RESET message has the function of blocking a networking line (the networking line is also called tcp connection) between the photovoltaic panel data acquisition equipment and the networking equipment so that the networking equipment can release connection resources, and the released connection resources can be used for responding to requests of other networking initiators to avoid the networking equipment from being in a downtime state. Under the condition, the networking device cannot necessarily receive the networking request of the undetermined photovoltaic panel data acquisition device, and cannot respond to the service request of the networking request of the undetermined photovoltaic panel data acquisition device.

Step S203, identify the os type and the request header in the requested device identifier.
Specifically, the operating system risk coefficient corresponding to the identified operating system type is determined according to a preset rule, and the field attribute risk coefficient of the request message header is determined, wherein the field attribute risk coefficient of the request message header is identified based on whether the UA is abnormal and the sequence difference of the http header.
Similarly, if the risk coefficient of the operating system is greater than the preset risk coefficient threshold of the operating system, 1 can be output, otherwise, 0 is output; if the field attribute risk coefficient is larger than the attribute preset risk coefficient threshold, 1 can be output, otherwise, 0 is output.
And step S204, determining a private line parameter according to the networking type parameter in the request.

Specifically, a photovoltaic panel data acquisition device vector type division model is called to determine a photovoltaic panel data acquisition device vector corresponding to the request, the safety weight of the photovoltaic panel data acquisition device vector is searched in a device type source set, a type risk coefficient is determined according to the safety weight, and the photovoltaic panel data acquisition device vector and the type risk coefficient are output.
Step S206, determining a continuous sequence behavior corresponding to the request.
In particular, the continuous sequence behavior may correspond to a standard industry networking vector in the present invention. Determining the continuous sequence behavior of the request according to the request and a standard industrial networking type identification library, searching the security weight of the continuous sequence behavior in a continuous preset networking source set, determining a standard industrial networking risk coefficient according to the security weight, and outputting the continuous sequence behavior and the standard industrial networking risk coefficient.
Step S207, determining the relay security weights of the first and second areas of the requested IP address.
Specifically, a first area risk coefficient is determined according to the relay safety weight of the first area, a second area risk coefficient is determined according to the relay safety weight of the second area, and the 2 risk coefficients are added to obtain an address risk coefficient. If the address risk coefficient is larger than the address preset risk coefficient threshold, 1 can be output, otherwise, 0 is output.
And step S208, outputting the networking safety vector and weighting and summing the risk coefficients.
Specifically, the output networking security vectors or 0/1 are connected by using "-", and the connected character string is called the networking security vector of the request. And carrying out weighted summation on the output risk coefficients.
In step S209, if the weighted and summed risk factor is greater than the threshold, step S210 is executed, otherwise, step S211 is executed.
Step S210, the tcp connection where the request is located is sealed, and the networking security vector corresponding to the request is cached.
In step S211, the flow ends.
Embodiments of the present invention also provide the following examples.
Step S301, a plurality of networking requests of successfully networked photovoltaic panel data acquisition devices are obtained, and networking type parameters are extracted from each networking request of the successfully networked photovoltaic panel data acquisition devices.
Specifically, a networking request of a plurality of successfully networked photovoltaic panel data acquisition devices is obtained, wherein a generation timestamp of the networking request of each successfully networked photovoltaic panel data acquisition device may be smaller than a generation timestamp of a networking request of an undetermined photovoltaic panel data acquisition device.
And extracting networking type parameters of networking requests of each successfully networked photovoltaic panel data acquisition device, wherein the networking requests of the successfully networked photovoltaic panel data acquisition devices comprise request address URLs, and the request address URLs are composed of destination ips, wherein the destination ips are the networking type parameters.
Step S302, a plurality of first special line networking related parameters are determined from the networking type parameters, and a special line networking characteristic group is screened from the first special line networking related parameters.
Specifically, the networking device splits each networking type parameter to obtain a character string set of each networking type parameter, and extracts a special networking related parameter (called as a first special networking related parameter) from the character string sets of all networking type parameters based on a frequent pattern extraction algorithm (the frequent pattern extraction algorithm may specifically be an FP Tree algorithm), wherein the first special networking related parameter is a character string with very high security weight in the character string sets of all networking type parameters. The specific process of the FP Tree algorithm is as follows: and excavating a sequence mode from the prefix with the length of 1, searching a corresponding projection database to obtain a frequent sequence corresponding to the prefix with the length of 1, then recursively excavating a frequent sequence corresponding to the prefix with the length of 2, and so on until a frequent sequence corresponding to a longer prefix cannot be excavated. After the networking equipment determines the related parameters of the first special line networking, the TF-IDF algorithm is adopted to screen out the related parameters of the high-frequency first special line networking in the related parameters of the first special line networking, and the screened related parameters of the high-frequency first special line networking are quantized into a special line networking feature set.
It should be noted that, because the FP Tree algorithm considers the sequence order among the sequence item sets, no candidate sequence is generated at the same time, and the suffix set is reduced quickly, the memory consumption is relatively small, and the effect is high when mining the related parameters of the private line networking.
Step S303, determining a networking type parameter filter of the networking request of each successfully networked photovoltaic panel data acquisition device according to the private line networking feature group.
Specifically, for each character string set of the networking type parameters, the character strings belonging to both the character string set of the networking type parameters and the character strings belonging to the special line networking characteristic group are respectively determined, and the determined character strings are connected by using "-" to obtain the networking type parameter filter of each networking type parameter.
Step S304, calling a photovoltaic panel data acquisition equipment vector type division model to determine a photovoltaic panel data acquisition equipment vector of each successfully networked photovoltaic panel data acquisition equipment networking request.
Specifically, the networking equipment calls a photovoltaic panel data acquisition equipment vector type division model to determine a photovoltaic panel data acquisition equipment vector of each successfully networked photovoltaic panel data acquisition equipment networking request, the photovoltaic panel data acquisition equipment vector can be used as a unique identity and used for identifying the photovoltaic panel data acquisition equipment on the bottom layer and the networking equipment end application program, and the realization that the bottom layer is judged through an id character string serving as a surface identification factor is avoided. The photovoltaic panel data acquisition equipment vector type division model can be realized based on JA3, HASH, FATT and the like.
It can be known that the mode of determining the photovoltaic panel data acquisition device vector of the networking request of the photovoltaic panel data acquisition device which is successfully networked and the device type vector of the undetermined photovoltaic panel data acquisition device of the networking request of the undetermined photovoltaic panel data acquisition device can be consistent, and only the processing object is changed.
Optionally, the networking device obtains a networking source safety vector of the networking request of each successfully-networked photovoltaic panel data acquisition device and a networking type safety vector of the successful networking, wherein the mode of determining the networking source safety vector of the networking is consistent with the mode of determining the undetermined networking source safety vector of the networking request of the undetermined photovoltaic panel data acquisition device, and only the processing object is changed. The successfully networked networking type safety vector comprises a type vector of a networking type parameter requested by the successfully networked photovoltaic panel data acquisition equipment, a photovoltaic panel data acquisition equipment vector requested by the successfully networked photovoltaic panel data acquisition equipment and a standard industrial networking vector requested by the successfully networked photovoltaic panel data acquisition equipment, wherein the special line networking vector of the networking type parameter filter is the HASH value of the networking type parameter filter, and the special line networking vector of the networking type parameter filter can also be called as the special line networking vector requested by the successfully networked photovoltaic panel data acquisition equipment. The specific process of determining the standard industrial networking vector of the networking request of each successfully networked photovoltaic panel data acquisition device comprises the following steps: splitting each successfully networked networking request of the photovoltaic panel data acquisition equipment to obtain a historical character string set of each successfully networked networking request of the photovoltaic panel data acquisition equipment, and extracting special line networking related parameters (called as third special line networking related parameters) from all the historical character string sets based on a frequent module sequence mode extraction algorithm (the frequent module sequence mode algorithm can be particularly an FP Tree algorithm), wherein the third special line networking related parameters are character strings with very high security weights in all the historical character string sets. And after the networking equipment determines the networking related parameters of the third special line, screening the networking related parameters of the high-frequency third special line by adopting a TF-IDF algorithm, and taking the screened networking related parameters of the high-frequency third special line as a high-frequency keyword set of a standard industrial networking protocol. For the historical character string set of each networking initiator, the character strings belonging to both the historical character string set and the high-frequency keyword set of the standard industrial networking protocol are respectively determined, and the determined character strings are connected by using < - >, so that the standard industrial networking filter of each networking initiator can be obtained.
The networking equipment determines a risk coefficient (called a first risk coefficient) of a networking source of a networking request of each successfully-networked photovoltaic panel data acquisition equipment based on a preset rule, wherein the first risk coefficient can correspond to the networking source risk coefficient of the networking request of the undetermined photovoltaic panel data acquisition equipment, the networking equipment determines a second risk coefficient according to a safety weight of a special line networking vector of a networking type parameter filter of the networking request of each successfully-networked photovoltaic panel data acquisition equipment in a special line networking vector of networking type parameter filters of networking requests of all successfully-networked photovoltaic panel data acquisition equipment, a safety weight of a standard industrial networking vector of the networking request of each successfully-networked photovoltaic panel data acquisition equipment in a standard industrial networking vector of networking requests of all successfully-networked photovoltaic panel data acquisition equipment, and a safety weight of the photovoltaic panel data acquisition equipment vector of networking requests of all successfully-networked photovoltaic panel data acquisition equipment, wherein the second risk coefficient and the same risk coefficient are determined, and the risk coefficient are determined, and the risk coefficient is only changed in the same mode as the risk coefficient and the networking processing mode of the networking source. The networking equipment acquires a first risk coefficient and a second risk coefficient of the networking request of each successfully networked photovoltaic panel data acquisition equipment, and if the sum of the first risk coefficient and the second risk coefficient of the networking request of all the successfully networked photovoltaic panel data acquisition equipment is greater than a preset second preset risk coefficient threshold, the networking equipment executes the following step S305; on the contrary, if the sum of the first risk coefficient and the second risk coefficient of the networking requests of all the successfully networked photovoltaic panel data acquisition devices is not greater than the preset second preset risk coefficient threshold, the networking devices can delete the networking requests of a plurality of successfully networked photovoltaic panel data acquisition devices.
The above process can be understood as follows: the networking equipment detects whether the networking request of the successfully networked photovoltaic panel data acquisition equipment is a safety request, if so, the special line networking vector of the networking type parameter filter, the photovoltaic panel data acquisition equipment vector and the special line networking feature group corresponding to the networking request of the successfully networked photovoltaic panel data acquisition equipment are stored into a corresponding database to update the database, so that the user can know that the updated database can be used for judging the networking safety level of the networking request of the photovoltaic panel data acquisition equipment to be determined; if not, discarding the data related to the networking request of the successfully networked photovoltaic panel data acquisition equipment, and indicating that the networking requests of the successfully networked photovoltaic panel data acquisition equipment cannot be used for judging the networking safety level of the networking request of the pending photovoltaic panel data acquisition equipment.
Step S305, storing the special line networking vectors of the multiple networking type parameter filters and the vectors of the multiple photovoltaic panel data acquisition devices into a preset networking source set, and storing the special line networking feature set into a special line networking type identification library.
Specifically, the networking device stores the private networking vectors of the networking type parameter filters of all the networking initiators which have been networked into a private networking preset networking source set so as to update the private networking preset networking source set. The updated preset networking source set of the private line networking can be used for determining a private line networking risk coefficient of a networking request of the data acquisition equipment of the undetermined photovoltaic panel.
And the networking equipment stores all photovoltaic panel data acquisition equipment vectors of networking requests of the successfully networked photovoltaic panel data acquisition equipment to the equipment type source set so as to update the equipment type source set. The updated device type source set can be used for determining the type risk coefficient of the networking request of the pending photovoltaic panel data acquisition device.
The networking equipment stores the special line networking characteristic group to a special line networking type identification library, and the special line networking type identification library can be used for determining a special line networking type identification of a networking request of the pending photovoltaic panel data acquisition equipment so as to determine a special line networking vector of the networking request of the pending photovoltaic panel data acquisition equipment.
It should be noted that, the standard industrial networking vector of the successfully networked photovoltaic panel data acquisition device networking request is not stored in the preset standard industrial networking source set because, although the plurality of successfully networked photovoltaic panel data acquisition device networking requests are safe, the plurality of successfully networked photovoltaic panel data acquisition device networking requests are not necessarily networking requests belonging to a plurality of standard industrial networking protocols.
Optionally, if the networking requests of the plurality of successfully networked photovoltaic panel data acquisition devices are networking requests of photovoltaic panel data acquisition devices belonging to a plurality of standard industrial networking protocols, the networking devices may divide the networking requests of the plurality of successfully networked photovoltaic panel data acquisition devices into a plurality of networking request queues of photovoltaic panel data acquisition devices, the number of the networking request queues of the photovoltaic panel data acquisition devices is equal to the number of the standard industrial networking protocols, each networking request queue of the photovoltaic panel data acquisition devices belongs to one standard industrial networking protocol, and the plurality of standard industrial networking protocols include: a step of collecting target information by stepping points; establishing a site stage; the number of the transverse moving stages, namely the networking request queues of the photovoltaic panel data acquisition equipment can be equal to 3.
And splitting the networking request of each successfully networked photovoltaic panel data acquisition device to obtain a historical character string set of the networking request of each successfully networked photovoltaic panel data acquisition device. For each photovoltaic panel data acquisition equipment networking request queue, extracting a special line networking related parameter (called as a second special line networking related parameter) from all historical character string sets contained in each photovoltaic panel data acquisition equipment networking request queue based on a frequent module sequence mode extraction algorithm (the frequent module sequence mode algorithm can be specifically an FP Tree algorithm), wherein the second special line networking related parameter is a character string with very high security weight in all the historical character string sets contained in each photovoltaic panel data acquisition equipment networking request queue. After the networking equipment determines the second special line networking related parameters of the networking request queue of each photovoltaic panel data acquisition equipment, the TF-IDF algorithm is adopted to screen out the high-frequency second special line networking related parameters in the second special line networking related parameters of the networking request queue of each photovoltaic panel data acquisition equipment, and the screened high-frequency second special line networking related parameters are used as the standard industrial networking characteristic group of the networking request queue of each photovoltaic panel data acquisition equipment, wherein the standard industrial networking characteristic group can be stored in a standard industrial networking type identification library, and the standard industrial networking type identification library can be used for determining the standard industrial networking vector of the networking request of the pending photovoltaic panel data acquisition equipment.
For a historical character string set of each networking initiator, character strings which belong to both a historical character string set and a standard industrial networking characteristic set are respectively determined, the determined character strings are connected by using < - >, a standard industrial networking parameter filter of each networking initiator is obtained, a standard industrial networking vector of the standard industrial networking parameter filter of the networking initiator which belongs to the same photovoltaic panel data acquisition equipment networking request queue (namely, a HASH value of the standard industrial networking vector of the standard industrial networking parameter filter) is quantized into the standard industrial networking vector of the standard industrial networking parameter filter to be determined, the standard industrial networking vector of the standard industrial networking parameter filter to be determined is stored into a standard industrial networking preset source set, and the standard industrial networking preset source set is updated. The updated preset networking source set of the standard industrial networking can be used for determining a standard industrial networking risk coefficient of a networking request of the data acquisition equipment of the photovoltaic panel to be determined.
If the networking requests of the photovoltaic panel data acquisition equipment which is successfully networked are not the networking requests of the photovoltaic panel data acquisition equipment of the standard industrial networking protocols, the networking equipment also acquires additional networking requests of the photovoltaic panel data acquisition equipment in the standard industrial networking protocols, determines a standard industrial networking vector of a standard industrial networking parameter filter of each networking request of the photovoltaic panel data acquisition equipment based on the networking requests of the photovoltaic panel data acquisition equipment, and stores the standard industrial networking vector to a standard industrial networking preset networking source set.
It should be noted that the preset networking source set of the private line networking, the device type source set and the preset networking source set of the standard industrial networking may be updated once at intervals, and the networking request of the photovoltaic panel data acquisition device acquired at the interval may be used as the networking request of the photovoltaic panel data acquisition device that has been successfully networked, and is used to update the preset networking source set of the private line networking, the device type source set and the preset networking source set of the standard industrial networking.
That is to say, the networking request of the pending photovoltaic panel data acquisition device can be used for updating the preset networking source set of the private line networking, the device type source set and the preset networking source set of the standard industrial networking next time.
Step S306, a networking request of the to-be-determined photovoltaic panel data acquisition equipment is obtained, and a networking safety vector of the to-be-determined photovoltaic panel data acquisition equipment networking request is generated, wherein the networking safety vector comprises a to-be-determined networking source safety vector and a to-be-determined networking type safety vector.
Step S307, determining networking request networking safety level of the data acquisition equipment of the undetermined photovoltaic panel according to the safety weight of the safety vector of the undetermined networking type in a preset networking source set and the safety vector of the source of the undetermined networking; the preset networking source set comprises networking type safety vectors of successful networking requested by a plurality of successfully networked photovoltaic panel data acquisition devices; if the networking security level of the networking request of the pending photovoltaic panel data acquisition equipment is a low security level, the networking circuit where the networking request of the pending photovoltaic panel data acquisition equipment is located is forbidden.
The specific processes of step S306 to step S307 can be referred to step S101 to step S104 in the corresponding embodiments described above.
