Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention discloses a method for displaying upgrading information of a substation SCD file. As shown in fig. 1, the method comprises the steps of:
step S101: and analyzing the first SCD file before upgrading and the second SCD file after upgrading to respectively obtain a first analysis result and a second analysis result.
The SCD file records various required attribute information, and the analysis result of the corresponding various attribute information can be obtained by analyzing the SCD file. The terms "first," "second," and the like, herein do not denote any order, quantity, or importance, but rather are used to distinguish one element from another, and are not described in detail.
Specifically, the step can be realized by the following processes:
the method comprises the following steps: analyzing the first SCD file, and acquiring a first Header attribute, a first substtation attribute, a first Communication attribute, a first IED attribute and a first APPID attribute contained in the first SCD file.
The first Header attribute comprises id, toolID and CRC attribute under the Header node. The first substtation attribute includes all attributes under the substtation node. The first Communication attribute includes all attributes under the Communication node. The first IED attribute includes all attributes under the IED node.
Furthermore, acquiring the first APPID attribute needs to be based on the first Communication attribute and the first IED attribute. Therefore, as shown in fig. 2, the step of obtaining the first APPID attribute is as follows:
step S201: and acquiring a first cbName, a first apName and a first ldInst of the intelligent electronic equipment as a sender according to the first Communication attribute.
The sending IED needs to resolve the Communication node. The Communication node includes a plurality of access points (access points), and each access point can send a message. The access point is described and uniquely identified by the name (idename) of each intelligent electronic device and the corresponding access point name (apame). And obtaining the message subscription relationship, namely obtaining the intelligent electronic equipment of a message as a sender and the intelligent electronic equipment of a message as a receiver. The first APPID attribute uniquely identifies the message subscription relationship of each access point under each Communication node, and the cbName and the ldInst describe and determine the APPID together.
Step S202: and acquiring a first cbName, a first apName and a first ldInst of the intelligent electronic device as a receiving party according to the first IED attribute.
The IED node comprises a plurality of ExtRef fields, a corresponding data set can be obtained through analysis of the ExtRef fields, and then the data set is analyzed to obtain a corresponding first cbName, a corresponding first apName and a corresponding first ldInst.
It should be understood that the order of step S201 and step S202 may be reversed, or may be performed simultaneously.
Step S203: the first cbName, the first apName and the first ldInst of the intelligent electronic device as the sender and the first cbName, the first apName and the first ldInst of the intelligent electronic device as the receiver are compared, respectively.
Through this step, the similarities and differences of the three are respectively compared to determine the first APPID attribute.
Step S204: and if the first cbName, the first apName and the first ldInst of the intelligent electronic device as the sender are completely the same as the first cbName, the first apName and the first ldInst of the intelligent electronic device as the receiver, determining a first APPID attribute.
Wherein, the first APPID attribute identifies the message subscription relation. If the three are completely the same, determining the message subscription relationship of the first APPID attribute identifier, namely determining the virtual loop of the first APPID attribute identifier.
Through the above process, all message subscription relations of the transformer substation are determined.
Step two: and analyzing the second SCD file to obtain a second Header attribute, a second substtation attribute, a second Communication attribute, a second IED attribute and a second APPID attribute contained in the second SCD file.
Similarly, the second Header attributes include id, toolID, and CRC attributes under the Header node. The second substtation attribute includes all attributes under the substtation node. The second Communication attribute includes all the attributes under the Communication node. The second IED attributes each include all attributes under the IED node.
As shown in fig. 3, the process of obtaining the second APPID attribute is as follows:
step S301: and acquiring a second cbName, a second apName and a second ldInst of the intelligent electronic device as the sender according to the second Communication attribute.
Step S302: and acquiring a second cbName, a second apName and a second ldInst of the intelligent electronic device as a receiving party according to the second IED attribute.
Step S303: and respectively comparing the second cbName, the second apName and the second ldInst of the intelligent electronic device as the sender with the second cbName, the second apName and the second ldInst of the intelligent electronic device as the receiver.
Step S304: and if the second cbName, the second apName and the second ldInst of the intelligent electronic device as the sender are completely the same as the second cbName, the second apName and the second ldInst of the intelligent electronic device as the receiver, determining a second APPID attribute.
And the second APPID attribute identifies the message subscription relation.
The process of acquiring the second APPID attribute is the same as the process of acquiring the first APPID attribute, and is not described herein again.
It should be understood that the order of the first step and the second step can be exchanged, and can also be performed simultaneously.
Step S102: and comparing the first analysis result with the second analysis result to obtain the upgrading information.
By comparing the first analysis result and the second analysis result, the difference of various attribute information can be determined. And if the second analysis result changes relative to the first analysis result, obtaining corresponding upgrading information. The upgrade information includes: the total-station upgrading information and the intelligent electronic equipment upgrading information.
Specifically, the step can be realized by the following process:
the method comprises the following steps: and acquiring a basic parameter record of the Substation of the total station upgrading information according to the difference of the first Header attribute and the second Header attribute and the difference of the first substtation attribute and the second substtation attribute.
For example, if the CRC (cyclic redundancy check) attribute of the IED node of the second SCD file changes from the first SCD file, it indicates that the intelligent electronic device of the intelligent substation has changed, and it is recorded in the substation basic parameter record of the total station upgrade information.
Step two: and acquiring the addition and deletion records of the intelligent electronic equipment of the total station upgrading information according to the difference of the first Name attribute and the second Name attribute of the intelligent electronic equipment.
The first Name attribute belongs to the first IED attribute, and the second Name attribute belongs to the second IED attribute.
Specifically, the first Name attribute of the intelligent electronic device in the first SCD file is used as the deletion record of the intelligent electronic device of the total-station upgrade information if the second SCD file does not correspond to the first Name attribute. On the contrary, the second Name attribute of the intelligent electronic device in the second SCD file is used as the added record of the intelligent electronic device of the total station upgrade information when the first SCD file does not correspond to the second Name attribute.
Step three: and acquiring a modification record of the intelligent electronic equipment of the total station upgrading information according to the difference of the first APPID attribute and the second APPID attribute.
Since the APPID uniquely identifies the message subscription relationship, and the modification of the APPID is the modification of the message subscription relationship and the upgrade modification of the intelligent electronic device, the result is recorded in the modification record of the intelligent electronic device of the total station upgrade information by comparing the APPID attributes of the first SCD file and the second SCD file.
Step four: and obtaining GOOSE addition and deletion modification and SV addition and deletion modification records of the upgrading information of the intelligent electronic equipment according to the difference of the first MAC-Address attribute and the second MAC-Address attribute, the first VLAN-ID attribute and the second VLAN-ID attribute, the first VLAN-PRIORITY attribute and the second VLAN-PRIORITY attribute, and the first APPID attribute and the second APPID attribute under the same message subscription relationship.
The first MAC-Address attribute, the first VLAN-ID attribute and the first VLAN-PRIORITY attribute belong to a first Communication attribute. The second MAC-Address attribute, the second VLAN-ID attribute, and the second VLAN-PRIORITY attribute belong to a second Communication attribute.
Specifically, although the intelligent electronic device as the sender and the intelligent electronic device as the receiver of the packet do not change, if at least one of the first MAC-Address attribute and the second MAC-Address attribute, the first VLAN-ID attribute and the second VLAN-ID attribute, the first VLAN-PRIORITY attribute and the second VLAN-PRIORITY attribute, and the first APPID attribute and the second APPID attribute are different, the parameter of the packet itself changes. And recording the result in GOOSE (general object-oriented substation event) adding and deleting modification and SV (sampling value) adding and deleting modification records of the upgrading information of the intelligent electronic equipment.
Step five: and acquiring basic parameter log records of the intelligent electronic equipment of the upgrading information of the intelligent electronic equipment according to the first ConfigVersion attribute and the second ConfigVersion attribute of the same intelligent electronic equipment, the first Desc attribute and the second Desc attribute, the first ManufatureAttribute and the second ManufatureAttribute, the first Name Attribute and the second Name Attribute, and the difference between the first Type Attribute and the second Type Attribute.
The first Name attribute, the first ConfigVersion attribute, the first Desc attribute and the first Manufacture attribute belong to a first IED attribute. The second Name attribute, the second ConfigVersion attribute, the second Desc attribute and the second Manufacture attribute belong to a second IED attribute.
It should be understood that the order of the first step to the fifth step may be changed arbitrarily or may be performed simultaneously.
Step S103: and acquiring the hash value of the intelligent electronic equipment.
The hash value is a hash function, and generally, each intelligent electronic device may correspond to one hash value, but there may be a case where the hash values collide. In a preferred embodiment of the present invention, the hash value is established by the following method:
the method comprises the following steps: according to the name of the intelligent electronic equipment, a first letter group, a number group and a second letter group of the name of the intelligent electronic equipment are obtained.
The name of the intelligent electronic equipment is sequentially a first letter group, a number group and a second letter group from left to right. For example, if the name of the intelligent electronic device is MT101A, the first letter group is MT, the number group is 101, and the second letter group is a.
Step two: and calculating the hash value of the intelligent electronic device according to the (key) a multiplied by key + b.
Where a represents the sum of the lexicographic orders of the first alphabet group, key represents the number group, and b represents the sum of the lexicographic orders of the second alphabet group. The lexicographic order refers to the number of the letter in the order of 26 letters in english. For example, M is ranked at 13, with 13 in the lexicographic order; t is arranged at the 20 th position, and the lexicographic order is 20; the sum a of the lexicographic orders of the first alphabet is 33. The number group is 101, then the key is 101. The A is arranged at the 1 st position, the lexicographic order is 1, and the sum b of the lexicographic orders of the second letter group is 1. (key) 33 × 101+1 3334. It should be understood that some intelligent electronic devices do not have a second alphabet, and the sum of the lexicographic orders of the second alphabet is 0.
Preferably, since the hash values of two different intelligent electronic devices may be the same to cause a collision, after step S103, to solve the problem, the method of the embodiment of the present invention may further include the following steps:
the method comprises the following steps: and if the hash values of the at least two intelligent electronic devices are the same, determining the function types of the at least two intelligent electronic devices.
Under the node of the substtation of the SCD file, classifying the intelligent electronic equipment according to functions according to the actual condition of the transformer Substation to obtain the function type.
Step two: and linking the hash value of the intelligent electronic equipment with the linked list corresponding to the function category of the intelligent electronic equipment, so that the hash value of the intelligent electronic equipment points to the address of the upgrading information of the intelligent electronic equipment.
And when the hash values of at least two intelligent electronic devices conflict, the hash values of the intelligent electronic devices are linked with the linked list corresponding to the function categories of the intelligent electronic devices by adopting a chain address method. This allows each hash value to point to a different address. Even if the function types of the at least two intelligent electronic devices are the same, the hash values of the intelligent electronic devices can be corresponding to the unique upgrading information through subsequent steps due to the fact that the pointed addresses of the intelligent electronic devices are different, and conflict cannot be generated.
Step S104: and respectively associating the hash value of the intelligent electronic equipment with the upgrading information of the intelligent electronic equipment and the name of the intelligent electronic equipment.
Through the hash value, the name of the intelligent electronic device can be associated with the corresponding upgrading information.
Step S105: and displaying a visual report of the upgrading information of the intelligent electronic equipment corresponding to the name of the intelligent electronic equipment according to the name of the intelligent electronic equipment input by the user.
Specifically, the visual report can be obtained based on the existing development platform according to the actual situation. For example, in a preferred embodiment, the visualization report is based on the Qt development platform and is obtained through the ModelView framework and the GraphcsView framework of the Qt visual library. The visual report includes: the system comprises a visualization report of the upgrade information of the whole station and a visualization report of the upgrade information of the intelligent electronic equipment.
FIG. 4 illustrates a resulting content diagram of a visual report of upgrade information. The visual report is divided into two parts, namely a visual report of the upgrade information of the whole station and a visual report of the upgrade information of the intelligent electronic equipment. In fig. 4, a total station graphic comparison report is used to represent a visual report of total station upgrade information, and an intelligent electronic device graphic comparison report is used to represent intelligent electronic device upgrade information. The debugging personnel can see the comparison result of the basic parameters of the intelligent substation in the visual report of the total station upgrading information, and can see the conditions of addition, deletion and modification of all intelligent electronic equipment after the upgrading. According to the modification catalog of the intelligent electronic equipment in the visual report of the total station upgrading information, a debugging person can search the specific modification condition of the intelligent electronic equipment in the visual report of the intelligent electronic equipment upgrading information, and the modification condition comprises a GOOSE/SV virtual circuit adding and deleting modification report, a GOOSE/SV communication parameter report and an intelligent electronic equipment basic parameter report.
Table 1 specifically shows a visualization report of total station upgrade information. The content of table 1 is divided into two parts, namely an intelligent electronic device list and basic parameters of an intelligent substation. In the list bar of intelligent electronic devices, the name of the intelligent electronic device is preceded by!
