The terms "first," "second," "third," and the like are used merely to distinguish between descriptions and are not to be construed as indicating or implying relative importance.
The setting value setting process of the relay protection device is to complete multi-level communication between the client and the management board, between the management board and each sub-board, as shown in fig. 1, and is a schematic diagram of a setting method of the relay protection device in the prior art, and includes: client, management board and multiple sub-boards.
As shown in fig. 1, firstly, data interaction is performed between a client and a management board through a 61850 protocol, wherein the specific process is as follows: the client side sends a command of writing and editing the fixed value area to the management board, when the management board receives the command of writing and editing the fixed value area, the fixed value editing area is selected, and after the selection is successful, the first response success information of the client side is returned; if the management board fails to select the fixed value area, immediately replying to failure of the client, and at the moment, not carrying out a setting flow on the client and the sub-board, and ending the whole setting process after the client receives the reply;
after receiving the response success information sent by the management board, the client sends a modification fixed value command to the management board, and after receiving the modification fixed value command, the management board executes the corresponding modification fixed value command and returns second response success information of the client; if the management board fails to write the fixed value command, the client fails to reply immediately, at the moment, the self and the sub board are not subjected to the setting process, and after the client receives the reply, the whole setting process is finished.
And after receiving the second response success information sent by the management board, the client sends a confirmation modification command to the management board, and after receiving the confirmation modification command, the management board locks and protects the fixed value in the updated memory and calculates the cyclic redundancy check (Cyclic Redundancy Check, CRC) of the updated fixed value, and after finishing the fixed value updating, the response information of successful setting is returned to the client.
After the management board returns response information of successful setting to the client, the management board starts downloading the fixed values of the sub-boards, at this time, the management board sends updated fixed values and calculated CRC to each sub-board, each sub-board locks and protects the fixed values in the updated memory according to the received updated fixed values, sends the CRC of the updated fixed values and the result of verification with the CRC of the updated fixed values, which are generated by calculation of the sub-board, to the management board, after the management board receives the information sent by each sub-board, the CRC is checked again, and if the verification is successful, the fixed values of the sub-boards are successfully issued.
It is understood that CRC is a hash function that generates a short fixed-bit check code based on data such as network packets or computer files, and is mainly used to detect or check errors that may occur after data transmission or storage, and uses the principles of division and remainder to perform error detection.
However, if the sub-boards are abnormal in the fixed value downloading process, if internal communication interruption, CRC (cyclic redundancy check) failure and other conditions occur, the sub-boards still operate according to the fixed value before setting, and at the moment, the setting flow of the relay protection equipment can be considered to be failed, but the setting flow is contradictory to the statement that the setting is successful for the client, and the time for each sub-board to receive updated fixed value data sent by the management board is different, and the time for locking protection is also different, so that the integral locking protection time of the relay protection equipment is greatly increased, and the relay protection equipment cannot work for a long time.
Therefore, the application provides the setting method of the relay protection equipment, which can enable the management board and each sub-board in the relay protection equipment to finish setting synchronously, thereby improving the reliability of setting the relay protection equipment.
Exemplary, as shown in fig. 2, a schematic diagram of a setting method of relay protection equipment according to an embodiment of the present application includes: a client, a management board and a plurality of sub-boards (not shown). The management board can be divided into a communication service module, a first fixed value downloading module, a first fixed value initializing module and a fixed value issuing module; the sub-board can be divided into a fixed value receiving module, a second fixed value downloading module and a fixed value initializing second module.
As shown in fig. 2, the client and the communication service module may perform data interaction through a 61850 protocol, where the principle of data interaction before the client receives the second response success information sent by the communication service module is the same as that of the above prior art, and will not be described herein.
And then, carrying out exemplary introduction on data interaction after the client receives the second response success information sent by the communication service module. For example, as shown in fig. 2, after receiving the second response success information sent by the communication service module, the client sends a confirmation modification command to the communication service module, and after receiving the confirmation modification command, the communication service module writes a second tuning parameter into the backup area and receives the first refresh value, where the second tuning parameter includes a second refresh value and a third verification code (may also be referred to as a CRC of the second refresh value), and the second refresh value is a value before tuning. At this time, the communication service module sends a fixed value refreshing flag of the communication service module to the first fixed value downloading module, the first fixed value downloading module prepares to lock, protect and update the fixed value in the memory, and then the communication service module starts fixed value downloading of each sub-board.
The specific process of the fixed value downloading of each daughter board can be as follows: the communication service module sends a first setting parameter to the fixed value sending module, the first setting parameter comprises a first refreshing value and a first verification code (also called CRC of the first refreshing value), the fixed value sending module receives the first setting parameter and then is in communication connection with the fixed value receiving module of each sub-board, the first setting parameter is sent to the fixed value receiving module of each sub-board at the moment, each fixed value receiving module solidifies the first refreshing value and sends a first fixed value refreshing mark to the corresponding second fixed value lower loading module, and the first fixed value refreshing mark is used for indicating that the fixed value receiving module successfully solidifies the first refreshing value, and at the moment, each second fixed value lower loading module is ready for locking protection to update the fixed value in the memory of the fixed value board. In addition, each fixed value receiving module returns a first fixed value refreshing mark to the fixed value issuing module, the fixed value issuing module sends each received first fixed value refreshing mark to the communication service module, and the communication service module solidifies the first refreshing value after receiving the first fixed value refreshing mark sent by the fixed value receiving module of each sub-board.
In one example, as shown in fig. 2, the specific process of each constant value receiving module curing the first refresh value may be: when the fixed value receiving module receives the first setting parameter sent by the fixed value issuing module, the fixed value receiving module checks the second verification code generated by calculating according to the first refreshing value with the first verification code in the first setting parameter, sends a check result and the second verification code to the fixed value issuing module, and the fixed value issuing module checks the second verification code again. If the verification is passed, the fixed value issuing module issues a command to enable the fixed value receiving module to write the first refreshing value into the local board. After completion, the fixed value issuing module sends a first fixed value refreshing mark to the communication service module.
It should be noted that, the communication service module may cure the first refresh value by writing the first refresh value into the current area of the management board.
After the communication service module solidifies the first refreshing value, a second constant value refreshing mark is sent to the first constant value downloading module and each second constant value downloading module, and the second constant value refreshing mark is used for indicating each second constant value downloading module to update the locking protection parameters; and when the first fixed value downloading module and each second fixed value downloading module receive the second fixed value refreshing mark sent by the communication service module, updating the preset locking protection parameter by using the first refreshing value.
In one example, as shown in fig. 2, after the communication service module solidifies the first refresh value, the service module may send a second constant refresh flag to the first constant download module and each second constant download module via a low voltage differential signaling (Low Voltage Differential Signaling, LVDS) bus.
For example, as shown in fig. 2, the first constant value downloading module, the communication service module and each second constant value downloading module may be respectively connected to the LVDS bus, and the communication service module may send the second constant value refreshing flag to each second constant value downloading module. The communication service module can firstly send a third constant value refreshing mark to the LVDS bus, and the third constant value refreshing mark is used for indicating the LVDS bus to send a second constant value refreshing mark to the first constant value downloading module and the second constant value downloading module; after the first fixed value downloading module and the second fixed value downloading module receive the second fixed value refreshing mark from the LVDS bus, the first fixed value downloading module and the second fixed value downloading module update the preset locking protection parameters according to the first refreshing value respectively.
In one example, as shown in fig. 2, after the first fixed value downloading module and the second fixed value downloading module update the preset locking protection parameters according to the first refresh value, the fixed value area module of the board is also re-initialized and the locking signal is cleared. Each second fixed value downloading module re-initializes the fixed value area component of the board and clears the locking signal, which comprises the following steps: each second fixed value downloading module sends a second setting success mark to a corresponding second fixed value initializing module, the second setting success mark is used for indicating that the first fixed value downloading module has completed updating the preset locking protection parameters, and after receiving the second setting success mark, the second fixed value initializing module re-initializes the fixed value area component of the board and clears the locking signal of the corresponding second fixed value downloading module; the process of re-initializing the fixed value area component of the board and clearing the locking signal by the first fixed value downloading module can be as follows: the first definite value downloading module sends a first setting success mark to the first definite value initializing module, the first setting success mark is used for indicating that the first definite value downloading module has completed updating the preset locking protection parameter, after the first definite value initializing module receives the first setting success mark, the fixed value area component of the board is re-initialized, and locking signals of the second definite value downloading module are cleared, and at the moment, the communication service module also returns setting success response information to the client.
According to the setting method of the relay protection equipment, the first fixed value refreshing mark is designed for each sub-board in the setting process, so that the management board only receives the first fixed value refreshing mark after each sub-board finishes solidification according to the first setting parameters, and then solidifies the first refreshing value, and the setting reliability of the relay protection equipment is improved. In addition, after the management board solidifies the first refreshing value, the locking protection is not directly carried out, and the second constant value refreshing mark and each sub-board are designed to carry out uniform locking protection refreshing parameters, so that the locking time of the relay protection equipment is greatly reduced, and the setting efficiency of the relay protection equipment is improved.
In one example, as shown in fig. 3, each constant value receiving module performs a process of curing the first refresh value, and further includes: when the fixed value receiving module receives the first setting parameter sent by the fixed value issuing module, the fixed value receiving module checks the second verification code generated by calculating according to the first refreshing value with the first verification code in the first setting parameter, and sends a check result and the second verification code to the fixed value issuing module, the fixed value issuing module checks the second verification code again, and if the verification fails or the verification fails, the fixed value receiving module does not respond to the command issued by the fixed value issuing module, and the fixed value issuing module sends a failed response state to the communication service module.
As shown in fig. 3, an exemplary embodiment of a method for setting relay protection equipment according to the present application is shown, if the communication service module receives a failure response from any one of the fixed value receiving modules within a preset period of time, the communication service module may use the second refresh value of the backup area to perform setting again. The communication service module sends the second setting parameters to the fixed value sending module, the fixed value sending module receives the second setting parameters and then is in communication connection with each fixed value receiving module, namely the fixed value receiving module sends the second setting parameters to each fixed value receiving module, and each fixed value receiving module can solidify the second refreshing value.
The principle that each fixed value receiving module cures the second refresh value and the fixed value setting process after curing are the same as the principle that each fixed value receiving module cures the first refresh value and the fixed value setting process after curing described above, and are not repeated here.
Because phenomena such as internal communication interruption, power failure restarting and the like possibly occur in the fixed value setting process of the relay protection equipment, in order to be convenient for knowing whether the relay protection equipment is interrupted at one stage in the fixed value setting process, whether the fixed value downloading of the daughter board is needed to be carried out again and whether fixed value data of a current area or a backup area is used for downloading, the downloading mark of the daughter board can be stored in the backup area.
Exemplary, as shown in fig. 4, a schematic state migration diagram of a downloading flag in relay protection equipment setting according to an embodiment of the present application is shown, where the downloading flag may include: finishing setting, loading, restoring, powering up and restoring and storing.
Wherein, the setting completion flag is 0X000, the flag in the lower package is 0XAAA, the flag in the restore is 0XBB, and the flag in the storage is 0XDDD.
As shown in fig. 5, an exemplary schematic diagram of a power-on interruption recovery flow of a relay protection device according to an embodiment of the present application is shown in fig. 4, where when an obtained flag is 0XAAA, the status of downloading is indicated as "in downloading", and the communication service module has already received a first refresh value, but has not written the first refresh value into a current area of a management board, and because there may be power failure during the period, the correctness of a second refresh value in a backup area at the moment can be determined, but the correctness of the first refresh value cannot be determined, so that power-on should use the second refresh value in the backup area for downloading; when the obtained mark is 0XDDD, the downloading state is indicated as 'in storage', and the correctness of the second refreshing value of the backup area can be ensured at the moment, but the correctness of the first refreshing value of the designated area can not be ensured, so that the second refreshing value of the backup area is used for downloading after power-on; when the obtained flag is 0XBBB, the downloading state is indicated as "in restore", and the data in this case are both the second refresh values, so that it can be ensured that the data in the backup area and the current area are both correct, and the data in any one area can be selected for downloading, for example, the second refresh value in the current area can be selected for downloading, which is not limited in the present application. When the lower loading mark is in other states, the power-on process does not need to perform fixed value reduction.
It should be noted that, in order to ensure that the relay protection device can reliably operate after setting, the embodiment of the present application further designs a checking mechanism for the fixed value data in the relay protection device, including:
(1) Self-checking of the self-board of the fixed value data: and after the relay protection equipment is electrified and the fixed value is set, performing self-checking on the fixed value data, comparing the CRC read and calculated from the current area of the management board with a first verification code stored in the current area of the management board, if the CRC is inconsistent with the first verification code stored in the current area of the management board, adding 1 to the error count, performing the operation once every 10 seconds, performing the operation 6 times, and if the error record is greater than or equal to 5, considering that the fixed value data is abnormal, and storing a self-checking record. However, because the power is lost in the setting process, the data of the current area may be damaged, and the situation that the verification is not passed is inevitable, so the self-verification of the fixed value of the daughter board can be performed after the management board is powered on, restored and assembled.
(2) Checking among boards of fixed value data: and during normal operation of the relay protection equipment, checking the fixed value data among boards in the main circulation, checking the verification code corresponding to the fixed value data calculated by the board by using the verification code corresponding to the fixed value data and the verification code sent by the management board through internal communication by using the sub board, and if the verification codes are inconsistent, storing the self-checking record.
(3) Initializing and checking fixed value data: and after reading the fixed value data from the current area of the management board during the power-on initialization of the relay protection equipment, checking the information such as the number, the positive and negative codes, the upper limit and the lower limit of the fixed value data with the information such as the number, the positive and negative codes, the upper limit and the lower limit and the like stored in the current area of the management board, and if any one of the information is inconsistent in checking, considering that the checking is abnormal and storing the self-checking record.
(4) Checking fixed value data of a current area: and during normal operation of the relay protection equipment, checking the information such as the number, the positive and negative codes, the upper limit and the lower limit of the constant value data in the current area of the management board and the information such as the number, the positive and negative codes, the upper limit and the lower limit and the like stored in the current area of the management board, and if any one of the information is inconsistent in checking, considering that the checking is abnormal and storing the self-checking record.
