Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
As used herein, the singular forms "a", "an" and "the" may include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises/comprising," "includes" or "including," etc., specify the presence of stated features, integers, steps, operations, components, parts, or combinations thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, components, parts, or combinations thereof. Also, as used in this specification, the term "and/or" includes any and all combinations of the associated listed items.
As described in the background art, the conventional technology needs additional auxiliary equipment when performing fixed value monitoring, and has a problem of high monitoring cost, and the inventor finds that the problem is caused because the equipment models of relay protection equipment currently put into use have certain differences, some relay protection equipment can be products before many years (such as products before 7-8 years, even products before 10 years), and other relay protection equipment can be products with relatively new models, so that the relay protection equipment has great differences in aspects of hardware configuration, function support and the like. If the constant value monitoring function is to be realized through the relay protection equipment under the condition of meeting the configuration of each relay protection equipment, the problem of high difficulty in upgrading and reconstruction exists, and the cost is increased.
In addition, the calculation power of some relay protection devices is difficult to satisfy the calculation with a large calculation amount under the condition of reserving a safety calculation power margin, such as failing to satisfy Cyclic Redundancy Check (CRC), Message-Digest Algorithm (MD 5), sha256 calculation, and the like. If a calculation with a large calculation amount is performed on the relay protection device which is configured relatively backward, the relay protection device cannot support or needs to be fully loaded to perform the calculation. Under the condition, the relay protection equipment cannot respond to emergency and emergency in time, the operation safety of the power grid is reduced, the relevant regulations of the power grid are not met, and the upgrading and transformation difficulty is further increased.
Based on the above, the application provides a relay protection fixed value monitoring method, a relay protection device, relay protection equipment and a computer readable storage medium, which have the advantages of less calculation amount and simple steps, can be applied to various relay protection devices to realize fixed value monitoring, and have strong applicability and can reduce monitoring cost.
In an embodiment, as shown in fig. 1, a relay protection constant value monitoring method is provided, and this embodiment is exemplified by applying the method to a relay protection device, and it is understood that the method may also be applied to other devices except the relay protection device. In this embodiment, the method includes the steps of:
step 110, obtaining target binary data; the target binary data includes binary data corresponding to each fixed value information.
The relay protection device may correspond to one or more items of fixed value information to be monitored, including but not limited to information such as a fixed value area number, a fixed value list, and/or a program version, and it may be understood that the fixed value information to be monitored may be determined according to an actual situation, and the fixed value information shown in the foregoing example may be added, deleted, or replaced, which is not specifically limited in this application.
Specifically, the relay protection device acquires target binary data, wherein the target binary data is a string of binary data and includes binary data corresponding to each piece of fixed value information. Further, before the relay protection device acquires the target binary data, the relay protection device can convert each fixed value information into corresponding binary data, and acquire the target binary data according to the binary data corresponding to each fixed value information; alternatively, the relay protection device may directly acquire the target binary data by communicating with an external device.
And step 120, splitting the target binary data to obtain each subdata, and performing exclusive-or operation on each subdata to obtain a monitoring feature code.
Specifically, after the target binary data is obtained, the relay protection device splits the target binary data to obtain a plurality of subdata, and the data lengths of any two subdata may be the same or different. If the subdata is combined in sequence according to a certain sequence, the target binary data can be obtained. Further, the relay protection device may split the target binary system according to a preset splitting rule, for example, the target binary system may be split according to a total length of the target binary data, a number of the fixed value information, and/or a length of each preset sub data.
After the sub-data is obtained by splitting, the relay protection equipment can perform XOR operation on the sub-data according to the bit and obtain a monitoring feature code, namely according to the bit
The monitoring feature code is obtained, wherein H is the monitoring feature code,
for XOR operation, d1Is the first subdata, d2Is the second subdata, and so on, dkIs the kth sub-data. The relay protection equipment carries out XOR operation on the first data of each subdata to obtain the first data of the monitoring feature codeAnd carrying out XOR operation on the second bit data of each subdata by the relay protection equipment to obtain the second bit data of the monitoring feature code, and so on, and respectively determining the data of each bit of the monitoring feature code.
When the lengths of the sub-data are not consistent, the length of the monitoring feature code can be determined according to the length of the longest sub-data, when the XOR operation is performed, the sub-data with the data length larger than or equal to the current calculation bit is determined as the target sub-data, and the XOR operation is performed on the value corresponding to the current calculation bit in each target sub-data, so as to obtain the value of the corresponding bit in the monitoring feature code. For example, if the data length of the sub-data 1 is 2 bits, the data length of the sub-data 2 is 3 bits, and the data length of the sub-data 3 is 4 bits, the length of the monitoring signature may be 4 bits. When the monitoring feature code is calculated, an exclusive or result of the first bit of the sub data 1, the first bit of the sub data 2, and the first bit of the sub data 3 may be determined as the first bit of the monitoring feature code, an exclusive or result of the second bit of the sub data 1, the second bit of the sub data 2, and the second bit of the sub data 3 may be determined as the second bit of the monitoring feature code, an exclusive or result of the third bit of the sub data 2 and the third bit of the sub data 3 may be determined as the third bit of the monitoring feature code, and the fourth bit of the sub data 3 may be determined as the fourth bit of the monitoring feature code.
In one embodiment, the relay protection device may perform an exclusive-or operation on each sub-data recursively to obtain the monitoring feature code. E.g. first pair d1And d2Carrying out XOR operation to obtain a first XOR result; the first XOR result and d3Carrying out XOR operation to obtain a second XOR result; the second XOR result with d4And performing XOR operation to obtain a third XOR result, and so on until the XOR operation of all the subdata is completed.
And step 130, determining a fixed value monitoring result according to the comparison result of the monitoring feature code and the preset feature code.
In one embodiment, the preset feature code may be stored in the background system. And the fixed value monitoring result is used for indicating whether the fixed value configuration of the relay protection equipment is abnormal or not.
Specifically, in the normal operation process of the relay protection device, the fixed value information does not change, and in the process, under the condition that the splitting rules are consistent, the monitoring feature code obtained by calculation according to the fixed value information does not change, so that the change of the fixed value execution state of the device can be monitored according to the monitoring feature code. Specifically, the relay protection device compares the monitoring feature code with the preset feature code to confirm the matching degree of the monitoring feature code and the preset feature code, and accordingly, a fixed value monitoring result is determined.
According to the relay protection setting value monitoring method, the monitoring feature codes are used as the unique identification of the setting value information of the equipment, when the setting value information is checked, all the setting value information does not need to be checked one by one, and the setting value execution condition of the equipment can be known only by checking the feature codes, so that the operation and maintenance workload of the equipment is reduced, and the operation and maintenance efficiency and the information checking accuracy are improved.
In the relay protection fixed value monitoring method, target binary data is obtained, wherein the target binary data comprises binary data corresponding to each piece of fixed value information; splitting target binary data to obtain each subdata, and performing XOR operation on each subdata to obtain a monitoring feature code; and determining a fixed value monitoring result according to the comparison result of the monitoring feature code and the preset feature code. Therefore, the relay protection equipment performs constant value monitoring by using binary data corresponding to the constant value information as a monitoring basis, has the advantages of less calculation amount and simple steps, and can complete constant value monitoring through the relay equipment, so that the monitoring cost and the difficulty of upgrading and reconstruction can be reduced. Meanwhile, in the monitoring process of the relay protection equipment, a safety calculation margin can be reserved, so that the safety of a power grid can be improved, the scheme of the application can be applied to most relay protection equipment, and the applicability is enhanced.
In an embodiment, referring to fig. 2, the step of splitting the target binary data to obtain each sub-data includes:
step 210, determining a splitting length;
and step 220, splitting the target binary data according to the split length to obtain each subdata with the split length.
The splitting length refers to a data length of each subdata, and it can be understood that the splitting length can be determined according to monitoring efficiency and accuracy, which is not specifically limited in the present application. In one embodiment, the splitting length may be greater than or equal to 16 bits, that is, the length of each sub-data may be greater than or equal to 16 bits, for example, may be 16 bits, 32 bits, or 64 bits, so that the monitoring accuracy may be ensured while the monitoring efficiency is improved.
Specifically, in the process of obtaining each subdata, the relay protection device determines a splitting length and splits the target binary data into a plurality of subdata with fixed lengths, and the data length of each subdata is the splitting length. When splitting the target binary data with length N by step length M, the obtained sub-data can be represented as d1，d2，……dkWherein, in the step (A),
k is the number of sub-data obtained after splitting,
is rounded up.
In one embodiment, considering that the data length of the target binary data is not necessarily an integral multiple of the split length, and the target binary data cannot be equally divided according to the split length, the relay protection device may zero-fill the sub-data with a shorter length until the length of the sub-data is equal to the split length, so that a plurality of sub-data with equal length may be obtained. It should be noted that the relay protection device may perform high-order zero padding, low-order zero padding, or zero padding at a specific position, which is not specifically limited in the present application, and only needs to make the length of each subdata equal to the splitting length. Further, the zero padding rule may be determined according to the splitting rule, for example, when the splitting rule is to split from high order to low order, a low order zero padding mode may be adopted; when the splitting rule is to split from low to high, a high zero padding mode can be adopted.
In this embodiment, the splitting length is determined, and the target binary data is split into a plurality of sub-data with the splitting length, so that a plurality of sub-data with the same length can be obtained, and it can be ensured that each monitoring feature code is obtained by xoring the same number of values, thereby reducing the interference effect and improving the monitoring accuracy.
In one embodiment, the step of splitting the target binary data to obtain each sub-data includes: and splitting the target binary data from the highest bit of the target binary data to the lowest bit of the target binary data to obtain each subdata.
Specifically, when splitting is performed, the relay protection device may split from the highest position to the lowest position, that is, the target binary data is split in order from left to right. In an example, taking target binary data as 10100101 as an example for explanation, when the split length is 3 bits, the split initial sub-data is: 101. 001, 01, at this time, zero padding can be performed on the sub data 01 at low order, and 010 can be obtained, so that the data length of each sub data is consistent. And the relay protection equipment performs exclusive OR operation on the three subdata 101, 001 and 010 according to bits, and obtains a monitoring feature code of 110.
In this embodiment, the relay protection device splits the target binary data in the direction from the highest position to the lowest position, and obtains each subdata, which has the advantages of less calculation amount and simple steps, and can complete the fixed value monitoring through the relay device, thereby reducing the monitoring cost and the difficulty of upgrading and transforming.
In one embodiment, the step of obtaining target binary data comprises: and binary data corresponding to each fixed value information is obtained, and the binary data corresponding to each fixed value information are merged according to a preset merging sequence to obtain target binary data.
The preset merging sequence is used for indicating the sequence of the binary data corresponding to each piece of constant value information in the target binary data, for example, the binary data corresponding to the constant value area code is a, the binary data corresponding to the constant value list is B, and the binary data corresponding to the program version is C, and the preset merging sequence is used for indicating whether each piece of binary data is merged according to the sequence of A, B, C, A, C, B or C, A, B.
Specifically, the relay protection device may obtain binary data corresponding to each fixed value information by reading data stored in the memory, or may obtain original data of each fixed value information, perform binary conversion on the original data to obtain binary data corresponding to each fixed value information, or perform communication with an external device to obtain each binary data. After the binary data corresponding to each fixed value information is obtained, the relay protection device can merge each binary data according to a preset merging sequence, and obtain a string of target binary data. Therefore, the constant value information can be merged according to the same merging sequence in the process of multiple constant value monitoring, the sequence of each constant value information in the target binary data is ensured to be unchanged, the subsequent splitting and monitoring are facilitated, and the calculated amount is reduced.
In one embodiment, the step of determining the fixed-value monitoring result comprises: if the monitoring feature code is consistent with the preset feature code, determining that the constant value configuration of the relay protection equipment is normal; otherwise, determining that the constant value configuration of the relay protection equipment is abnormal, and sending an alarm.
Specifically, the relay protection device compares the monitoring feature code with a preset feature code, and if the value of the monitoring feature code is the same as that of the preset feature code in each bit, it can be determined that the monitoring feature code is the same as the preset feature code, and it is determined that the configuration of the fixed value of the relay protection device is normal. Otherwise, if the value of the monitoring feature code on at least one bit is different from the value corresponding to the preset feature code, the monitoring feature code is considered to be inconsistent with the preset feature code, and the abnormal configuration of the fixed value of the relay protection device is determined. When the configuration is abnormal, the relay protection equipment can send out an alarm. In one embodiment, the relay protection device may display the monitoring feature code and the comparison result on a local display device, or transmit the foregoing information to a monitoring system for monitoring by operation and maintenance personnel.
To facilitate understanding of the aspects of the present application, a specific example will be described below. Referring to fig. 3, the method for monitoring the relay protection setting value of the present application includes:
and step 310, the relay protection equipment acquires all the fixed value information and respectively stores all the fixed value information as corresponding binary data.
And step 320, the relay protection equipment merges the binary data corresponding to each fixed value information according to a preset merging sequence, and obtains target binary data.
Step 330, the relay protection equipment splits the target binary data into a plurality of subdata with fixed length; the length of each subdata is the binary digit of the subdata. Specifically, the target binary data may be split according to the method shown in the above embodiment, and in the case that the target binary data cannot be equally split, zero padding is performed on the lower bits.
And 340, the relay protection equipment performs exclusive-or operation on the sub-data in sequence and recursively, and confirms the result of the exclusive-or operation as the monitoring feature code. The length of the monitoring feature code is consistent with the length of each subdata.
And 350, comparing the monitoring feature code with a preset feature code recorded in the background system by the relay protection equipment, and giving an alarm when the comparison result is inconsistent. When alarming is carried out, the relay protection equipment can display the monitoring feature code and the comparison result on local display equipment or transmit the information to a monitoring system so that operation and maintenance personnel can monitor the information.
The method is based on the self-coding technology, utilizes binary data of the constant value information as the calculation basis of the recursion characteristics, has the advantages of less calculation amount and simple steps, and is easy to modify and upgrade the existing equipment.
It should be understood that although the various steps in the flow charts of fig. 1-3 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least some of the steps in fig. 1-3 may include multiple steps or multiple stages, which are not necessarily performed at the same time, but may be performed at different times, which are not necessarily performed in sequence, but may be performed in turn or alternately with other steps or at least some of the other steps.
