Description

Technical Field

[0001] The present invention relates to the field of power systems, and more particularly, to a method, device, system and medium for verifying master-slave station monitoring information. Background Art

[0002] The traditional joint debugging of master-slave station monitoring information is mainly completed manually, and the joint debugging efficiency is relatively low. After introducing the automatic acceptance technology, the automatic acceptance device simulates the joint debugging between the slave station and the automatic acceptance module of the master station, and the joint debugging efficiency has been improved to a certain extent. However, with this automatic joint debugging method, the master station cannot understand the specific meaning expressed by the signals sent by the slave station. The slave station can only send signals in the order of signal numbers, and it requires the cooperation of personnel on both the master station and the slave station sides. When multiple master stations are simultaneously accepting, it is necessary to coordinate the cooperation of each master station. Moreover, it cannot effectively check the consistency of the master-slave station configurations, the flexibility of the joint debugging logic configuration is low, and the joint debugging result is greatly affected by time coordination, seriously affecting the joint debugging efficiency of master-slave station monitoring information. Summary of the Invention

[0003] The purpose of the present invention is to provide a method, device, system and medium for verifying master-slave station monitoring information, which solves the problem of low joint debugging efficiency of master-slave station monitoring information.

[0004] The above technical purpose of the present invention is achieved through the following technical solutions:

[0005] In the first aspect of the present invention, there is provided a method for verifying master-slave station monitoring information, which is applied to a slave station device. The method includes:

[0016] Based on ASCII, the feature code is sequentially converted into a binary code to obtain the second byte to the (m + 1)-th byte; where m represents the number of characters of the feature code;

[0018] In one implementation, the value of m is obtained as follows:

[0019] When the total number of characters of the name information is greater than the quantity threshold, m is equal to the quantity threshold;

[0020] When the total number of characters of the name information is less than or equal to the quantity threshold, m is equal to the total number of characters of the name information.

After receiving the three frames of the first message, the telecontrol device generates three frames of second messages corresponding to the time stamp of the first message.

[0023] Arrange the bytes of the number information, the total number of characters of the name information, and the bytes of the signature code in sequence to form multiple bytes.

[0024] Perform number system conversion on the multiple bytes in sequence to obtain the characters corresponding to each byte.

[0025] Form the first characteristic information of the signal according to the number information and the characters corresponding to each byte.

[0026] Compare the first characteristic information of the signal with the pre-configured second characteristic information. If the number information and the characters corresponding to each byte are the same, the signal verification passes; otherwise, the signal verification fails.

In the description of the present invention, "a plurality of" means two or more unless otherwise specifically defined.

[0044] Please refer to Figure 1 , Figure 1 which is a schematic flowchart of a method for verifying master and slave station monitoring information provided by an embodiment of the present invention. This method is applied to slave station devices and includes:

[0045] S101, parsing the remote device configuration description file to obtain the signal number information, name information and path name information.

[0046] In this embodiment, the RCD (Remote Configuration Description) remote device configuration description file is a file format used in the field of power system automation to describe the configuration information of remote devices (such as data communication network shutdown devices). It plays a crucial role in intelligent substations and is mainly used to achieve in-depth information interaction between the dispatching master station and the substation. The RCD file contains the configuration information of the remote device, such as the forwarding relationship of signals such as remote signaling, remote measurement, and remote control. It uses the E format description and UTF-8 encoding method. The naming format of the RCD file is usually: substation name_channel name_sequence number.rcd.

[0047] As a bridge for in-depth information interaction between the dispatching master station and the substation, the RCD file ensures the accuracy and consistency of data transmission between the substation and the dispatching master station.

[0048] The dispatching master station can remotely access the RCD files of the slave station through specific communication protocols (such as DL / T 476, DL / T 634.5104, etc.) to achieve remote monitoring and operation and maintenance of the substation.

[0049] Through the simulation device and the dispatching master station simulation system, the RCD file can be automatically generated and compared with the RCD file configured inside the telecontrol device to verify whether the configuration of the telecontrol device is correct.

[0050] The RCD file is synchronized with the SCD (Substation Configuration Description) file, the monitoring background database, etc. to ensure the configuration consistency of the substation automation system.

[0051] The standardized format of the RCD file enables devices from different manufacturers to share configuration information, reducing human errors and configuration inconsistencies. Through the automatic generation and verification mechanism, the configuration of the telecontrol device can be quickly verified, saving manpower and time. Supporting the remote access of the RCD file by the dispatching master station improves the remote monitoring and operation and maintenance efficiency of the substation.

[0052] Specifically, a joint debugging device is deployed in the slave station equipment. The joint debugging device includes a slave station data processing module and a slave station data sending module. Import the RCD file into the slave station data processing module, and then parse the RCD file to obtain the number information of all signals in the RCD file, such as 1, 2, 3, etc.; the name information of all signals, such as the position of the disconnector 50111; the path name information of all signals, such as the IEC61850 path name information, CD5011CTRL / 1$ST$Pos$stVal.

[0053] S102, extract the feature code of the name information according to the total number of characters of the name information; wherein, the feature code refers to the first letter of the characters or Chinese characters of the name information.

[0054] In this embodiment, the name information of the signals is composed of several characters. Therefore, in this embodiment, the feature code of the name information is extracted according to the total number of characters of the name information. For the information transmission of each signal, three frames of the first message need to be continuously sent, and the first message is a CMS message or an MMS message. The transmission interval time is T, and T can be set by on-site personnel according to the performance of telecontrol and master station equipment. If the signal is a remote signaling signal, the state values of the signal continuously sent three times are 0, 1, and 0 in sequence. If the signal is a remote measurement signal, the remote measurement values of the signal continuously sent three times are the point number plus the offset, and the offset can be set by on-site personnel. At present, since the substation equipment can only send signals in the order of point numbers, it is impossible to effectively check the configuration consistency of the master and substation equipment, resulting in low flexibility of the joint debugging logic configuration, and the joint debugging result is greatly affected by time coordination, seriously affecting the joint debugging efficiency of the master and substation monitoring information. Therefore, the present invention covers the bytes representing the time stamp in the three frames of the first message, and uses the time stamp to transmit the characteristic information of the signal. Without the cooperation of the operation and maintenance personnel of the master and substation equipment, the joint debugging result is not affected by time coordination, the joint debugging logic can be flexibly configured, the configuration consistency of the master and substation equipment can be effectively verified, and the same effect as the closed-loop joint debugging of the master and substation can be achieved without increasing the data transmission channel between the master and substation, effectively improving the automation level of the joint debugging of the master and substation monitoring information and greatly improving the joint debugging efficiency of the master and substation monitoring information.

[0055] Since each frame of the first message has 7 bytes representing the time stamp, three frames of messages are 21 bytes. In this embodiment, 1 byte is used to represent the length, and the remaining 20 bytes cover the bytes representing the name information of the signal, thus realizing the transmission of the signal meaning by using the bytes representing time.

[0056] Since the total number of bytes of the three frames of the first message is only 20, in this embodiment, the characters of the name information of the signal are analyzed. If the total number of characters of the name information is less than or equal to the quantity threshold (the quantity threshold is set to 20), the first letter of each character or Chinese character in the name information is extracted and combined in order to obtain the feature code of the name information.

[0057] If the total number of characters of the name information is greater than the quantity threshold, the first letters of the first x characters or Chinese characters in the name information and the first letters of the last x characters or Chinese characters in the name information are extracted and combined in order to obtain the feature code of the name information, where the value of x is half of the quantity threshold.

[0058] For example, taking the telecontrol signal "Isolator position of 50111" as an example, the number of the telecontrol signal "Isolator position of 50111" in the RCD is "1", and the number information of the telecontrol signal "Isolator position of 50112" in the master station configuration is "1". The substation data processing module parses the RCD file to obtain the first telecontrol signal, with the number being 1, the name information being "Isolator position of 50111", and the path name information being "CD5011CTRL / 1$ST$Pos$stVal". The number of the first telecontrol signal is 1; the signal name "Isolator position of 50111" of the first telecontrol signal contains a total of 9 characters or Chinese characters, the number of characters of the signal name is "9" and less than 20, and the feature code composed of the first letters of these 9 characters or Chinese characters arranged in sequence is "50111gdwz".

[0059] S103. Determine the information table of the signal according to the number information, the number of characters of the signal name, and the path name information.

[0060] In this embodiment, the information table of the signal is successively composed of four pieces of information such as "1", "9", "50111gdwz", and "CD5011CTRL / 1$ST$Pos$stVal".

[0061] S104. Successively perform number system conversion on the number of characters of the signal name and the feature code to obtain multiple bytes.

[0062] In this embodiment, successively perform ASCII encoding on the number of characters of the signal name and the feature code to obtain multiple bytes. Specifically: convert the number of characters of the signal name into binary encoding based on the ASCII code to obtain the first byte; convert the feature code into binary encoding successively based on the ASCII code to obtain the second byte to the (m + 1)-th byte; where m represents the number of characters of the feature code; combine the first byte with the second byte to the (m + 1)-th byte in sequence to obtain multiple bytes.

[0063] For example, the substation data processing module sends the information record of the telecontrol signal "Isolator position of 50111" to the substation data sending module. In the substation data sending module, convert the second feature code and the third feature code in the information record of the telecontrol signal "Isolator position of 50111": based on the ASCII code rule, the ASCII code of the number of characters "9" of the signal name is 56, which is converted into eight-bit binary code to form the first byte; based on the ASCII code rule, the ASCII codes of the feature code "50111gdwz" are 53, 48, 49, 49, 49, 103, 100, 119, 122 respectively, and are all converted into eight-bit binary encoding, and successively form the second byte to the tenth byte.

[0064] Specifically, the value-taking method of m is as follows: when the total number of characters of the name information is greater than the quantity threshold, m is equal to the quantity threshold;

[0065] When the total number of characters of the name information is less than or equal to the quantity threshold, m is equal to the total number of characters of the name information.

[0066] For example, when the total number of characters of the name information is 25, at this time, the total number of characters of the name information is greater than 20. Therefore, at this time, the value of m is 20. After performing ASCII encoding on the number of characters of the signal name and the signature code, 21 bytes are obtained.

[0067] When the total number of characters of the name information is 11, at this time, the total number of characters of the name information is less than 20. Therefore, at this time, the value of m is 11. After performing ASCII encoding on the number of characters of the signal name and the signature code, 12 bytes are obtained.

[0068] S105. Cover the bytes representing the time stamp in the first message with the multiple bytes in sequence to form a new time stamp of the first message.

[0069] In this embodiment, based on the 1st to 10th bytes described in the above step S104, assuming that the first message uses a CMS message, a binary coding sequence of seven bytes of the time stamp in the 104 message format when establishing the first frame of the CMS message is established. The 1st to 7th bytes are used to cover the seven bytes of the first frame of the first message to form a new time stamp of the message, which is set as the time stamp of the first frame of the CMS message; a binary coding sequence of seven bytes of the time stamp in the 104 message format when establishing the second frame of the CMS message is established. The 8th to 10th bytes are used to cover the first three bytes (the 8th to 10th bytes) and form a new time stamp, which is set as the time stamp of the second frame of the CMS message. Since the time stamp of the third frame of the CMS message remains unchanged.

[0070] The substation data sending module emulates the 5011 switch measurement and control device, and continuously sends three CMS messages to the telecontrol according to the IEC61850 path name "CD5011CTRL / 1$ST$Pos$stVal" in the information record of the teleindication signal "50111 disconnector position". The message interval is 0.2 s. The teleindication status value of the first frame of the CMS message is 0, the teleindication status value of the second frame of the CMS message is 1, and the teleindication status value of the third frame of the CMS message is 0. Set the time stamps of the three frames of CMS messages according to the bytes provided above in sequence.

[0071] S106. Send the first message with the adjusted time stamp bytes to the telecontrol device according to the path name information in the information table. After receiving the three frames of the first message, the telecontrol device generates three frames of second messages corresponding to the time stamps of the first message and sends them to the master station device.

[0072] In this embodiment, the telecontrol device sequentially receives three frames of CMS messages, and sequentially overwrites the 1st to the (m + 1)th bytes of the three frames of CMS messages to the bytes representing the time stamp in the second messages of the first to the third frames, and the un-overwritten bytes remain unchanged. The time stamps in the three frames of MMS or CMS messages of the set signal are sequentially the same as the time stamps of the three frames of second messages after being overwritten. And forward the three frames of second messages to the master station device. Optionally, the second message uses the 104 message.

[0073] Please refer to Figure 2 , Figure 2 FIG. is another flowchart of a method for verifying master-slave station monitoring information provided by an embodiment of the present invention. This method is applied to the master station device, and the method includes:

[0074] S201, receive three frames of second messages sent from the slave station device, parse the three frames of the second messages, and obtain the bytes of the number information, the bytes of the total number of characters of the name information, and the bytes of the signature code; wherein, the generation process of the second message is as follows: parse the telecontrol device configuration description file to obtain the number information, name information, and path name information of the signal; extract the signature code of the name information according to the total number of characters of the name information; wherein, the signature code refers to the first letter of the characters or Chinese characters of the name information; determine the information table of the signal according to the number information, the number of characters of the signal name, the signature code, and the path name information; sequentially encode the number information, the number of characters of the signal name, and the signature code to obtain multiple bytes; sequentially overwrite the bytes representing the time stamp in the first message with the multiple bytes to form a new time stamp of the first message; send three frames of first messages with adjusted time stamp bytes to the telecontrol device according to the path name information in the information table. After receiving the three frames of first messages, the telecontrol device generates three frames of second messages corresponding to the time stamps of the first messages.

[0075] In this embodiment, after the master station device receives the second message, the master station data processing module configured by the master station device parses the second message to obtain the bytes of the number information of the signal, the bytes of the total number of characters of the name information, and the bytes of the signature code.

[0076] S202, sequentially arrange the bytes of the number information, the bytes of the number of characters of the signal name, and the bytes of the signature code to form multiple bytes.

[0077] In this embodiment, the binary codes representing the time stamp in three consecutive 104 messages of the same signal are sequentially arranged to form a data set including 21 bytes.

[0078] S203, sequentially perform number system conversion on the multiple bytes to obtain the characters corresponding to each byte.

[0079] In this embodiment, based on the ASCII code rule, 21 bytes are converted into corresponding 21 characters. The first character is the total number of characters m of the signature of the signal, and the 2nd to the (m + 1)th characters are extracted as the signature. For example, according to the ASCII code rule, the binary codes representing time stamps in three 104 messages with the serial number information "1" are converted into characters and arranged in chronological order to form a data set containing 21 bytes. The first character is "9", that is, the total number of characters m of the signature, indicating that there are 9 characters in the signature. Therefore, the 2nd to the 10th characters, that is, "50111gdwz", are the signature of the information name.

[0080] S204. According to the serial number information and the characters corresponding to each byte, the first feature information of the signal is formed.

[0081] In this embodiment, "1", "9", and "50111gdwz" are combined to form the first feature information of the signal.

[0082] S205. Compare the first feature information of the signal with the pre-configured second feature information. If the serial number information and the characters corresponding to each byte are the same, the signal verification passes; otherwise, the signal verification fails.

[0083] In this embodiment, the master station data processing module sends the first feature information to the master station data verification module. The master station data verification module extracts the master station configuration. The signal name with the serial number "1" in the master station configuration is "50112 disconnector position", its serial number information is "1", the total number of characters of the signature is "9", and the signature is "50112gdwz". The serial number information with the serial number "1", the total number of characters of the signature being "9", and the signature being "50112gdwz" configured for the master station device are combined to form the second feature information of the signal. The master station data verification module compares the first feature information with the second feature information. Obviously, "50111gdwz" recorded in the first feature information is different from "50112gdwz" recorded in the second feature information. Therefore, the signal verification fails and a signal error is prompted.

After receiving the three frames of the first message, the remote control device generates three frames of the second message corresponding to the time stamp of the first message and sends them to the master station device.
