This alarm exception needs to be eliminated by the operation and maintenance personnel on site. The operation and maintenance personnel on site not only need complex safety measures and processes, but also need to spend a lot of time and manpower to manually check the data.

[0024] In the following description, for purposes of explanation and not limitation, specific details are set forth such as particular architectures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. However, it will be apparent to those skilled in the art that the present application can be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known methods, devices, circuits, and

[0026] It will be understood that the term "and / or," when used in the specification and in the following claims, refers to one and / or a combination of the associated listed items.

[0027] As used in this specification and claims, the terms "if" and "when" can be interpreted to mean "upon determination" or "in response to a determination" or "in response to detecting," depending on the context. Similarly, the phrase "if determined" or "if detected [the described condition or event]" can be interpreted to mean "upon determining" or "in response to determining" or "upon detecting [the described condition or event]" or "in response to detecting [the described condition or event]," depending on the context.

[0028] In addition, the terms "first," "second," "third," etc. as used in the description of the specification and the appended claims are not used to denote or imply relative importance but are used to distinguish one element from another.

[0029] Reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present application. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" or "in a various embodiment" or "in some embodiments" in various places throughout this specification are not necessarily all referring to the same embodiment, unless otherwise specified.

[0030] In a power system, secondary equipment can control, protect, measure and monitor the power system to ensure the safe and stable operation of the power system. The secondary equipment can include a relay protection device, an automatic power generation regulating device, an excitation control device, a load control device, a telemetry and remote control device, a data acquisition device, a monitoring system, a communication device, etc. To ensure the safe and stable operation of the power system, an operation and maintenance personnel needs to operate and maintain the secondary equipment.

[0031] In the traditional technical solution, when the operation and maintenance personnel needs to remotely upgrade the secondary equipment, since the device APP (Application, application program) of the secondary equipment after the upgrade does not match the data fixed in the non-volatile memory in the secondary equipment, the secondary equipment can generate a self-check alarm exception. This self-check alarm exception needs to be eliminated by the operation and maintenance personnel on site. The operation and maintenance personnel on site not only needs complex safety measures and processes, but also needs to spend a lot of time and manpower to manually check the data. The automation level and the intelligent level of the operation and maintenance of the secondary equipment in the traditional technical solution are not high.

[0032] Therefore, the embodiments of the present application provide a data writing method, which can avoid the self-check alarm exception of the secondary equipment after the remote upgrade, and improve the automation level and the intelligent level of the operation and maintenance of the secondary equipment.

[0033] The technical solutions of the embodiments of the present application will be described below with reference to the accompanying drawings.

[0034] As shown in Figure 1 Fig. 1 is a schematic diagram of an application scenario of a data writing method provided by the embodiments of the present application. As shown in Figure 1The plurality of processors correspond to a plurality of non-volatile memories (a first non-volatile memory, a second non-volatile memory, a third non-volatile memory and a fourth non-volatile memory). The plurality of processors are connected with the corresponding non-volatile memories respectively, can read instructions and data from the corresponding non-volatile memories, and perform operation and processing on the data. The plurality of processors are connected with the volatile memories respectively, for reading data in the non-volatile memories and temporarily storing to the volatile memories. The plurality of processors include an MCPU (Management CPU), a PCPU (Protection CPU), a BCPU (Blocking CPU) and an SCOM (Communication Module). The MCPU is a management mainboard with an operating system, used for managing and coordinating information of each subboard, and performing device interface display and external communication interaction. The PCPU is a core protection CPU in the relay protection device, is a subboard without an operating system, and can complete execution of a relay protection logic segment. The BCPU is a core blocking CPU in the relay protection device, is a subboard without an operating system, is a double-redundant PCPU, and is used for completing execution of the relay protection logic segment. The SCOM is a subboard without an operating system, used for high-speed real-time bus communication between internal subboards of the device, and interacting core data of the relay protection device.

[0035] The data writing method provided by the embodiment of the application can be applied to a processor, and the processor is configured in a control device. The control device can be a secondary device in a power system, for example, a relay protection device, an automatic generation regulation device, an excitation control device, a load control device, a telemetry and remote control device, a data acquisition device, a monitoring system, a communication device and the like. The data writing method provided by the embodiment of the application is exemplarily described taking the relay protection device as an example. It can be understood that the data writing method provided by the embodiment of the application can also be used in other devices which need to write data.

[0036] In the embodiment of the application, an operation and maintenance personnel can determine the required function or the required modified fixed value of the relay protection device by analyzing the actual situation of a substation in a power system, develop corresponding software, and generate a remote operation and maintenance upgrade package to ensure the correctness and reliability of the software function. The remote operation and maintenance upgrade package is transmitted to the relay protection device through a power grid dispatching master station to realize remote upgrade of the relay protection device without manual on-site intervention.

[0037] The data writing method provided by the embodiment of the application will be exemplarily described below in combination with the method flow in Figures 2 to 5

[0038] As shown in FIG. 1, the data writing method provided by the embodiment of the application includes the following steps. Figure 2 ​As shown, it is a flow diagram of a data writing method provided by an embodiment of the application. After receiving the remote operation and maintenance upgrade package sent by the power grid dispatching master station, the relay protection device performs the following steps:

[0039] Step S201: receiving the remote operation and maintenance upgrade package.

[0040] In the embodiment of the application, the power grid dispatching master station can send the remote operation and maintenance upgrade package to the management processor of the relay protection device, and the management processor can be a mainboard with an operating system. For example, the management processor can be an MCPU.

[0041] The remote operation and maintenance upgrade package can include a to-be-parsed data file and a plurality of update application program packages. The to-be-parsed data file can include the setting value data required for remote upgrade of the relay protection device. The setting value data can be the setting parameters required for the protection action of the relay protection device, including but not limited to the action value, the time setting value, the specific curve, and the logic relationship data. The action value can be the action threshold value of the relay protection device, for example, the action current value of the overcurrent relay. The time setting value can be the action delay time of the relay protection device, for example, the delay time of the overcurrent relay. The specific curve can be the mathematical expression of the action characteristic of the relay protection device, for example, the inverse time-lag characteristic curve of the overcurrent relay. The logic relationship data can be the logic relationship data of the action of the relay protection device, for example, the interlocking relationship data between multiple relays.

[0042] In the embodiment of the application, the file format of the to-be-parsed data file can be a binary format. Since the file format of the binary format can save storage capacity, when the processor receives the to-be-parsed data file, the occupation of the to-be-parsed data file to the memory of the processor can be reduced, thereby saving storage resources and prolonging the use time of the hardware.

[0043] The number of the plurality of update application program packages can be consistent with the number of the processors in the relay protection device. For example, when the relay protection device includes four processors (one mainboard and three slave boards), the remote operation and maintenance upgrade package contains four update application program packages. The four update application program packages correspond to the four processors respectively, and are used for remote operation and maintenance upgrade of the relay protection device.

[0044] Step S202: verifying the remote operation and maintenance upgrade package to obtain a verification result, the verification result being used to represent whether the remote operation and maintenance upgrade package carries the to-be-parsed data file and at least one update application program package.

[0045] In the embodiments of the present application, the at least one update application package can be an update application package corresponding to a management processor in the relay protection device, or an update application package corresponding to a management processor (a mainboard processor with an operating system) and a non-management processor (a subboard processor without an operating system). It can be understood that when the relay protection device only includes one management processor, the remote operation and maintenance upgrade package can only carry one update application package. When the relay protection device includes one management processor and at least one non-management processor, the remote operation and maintenance upgrade package can carry at least one first update application package and a second update application package. The at least one first update application package corresponds to the at least one non-management processor in one-to-one correspondence, the at least one non-management processor is configured to run the at least one first update application package, and the management processor is configured to run the second update application package.

[0046] Step S203: If the verification result indicates that the remote operation and maintenance upgrade package carries the to-be-analyzed data file, the at least one first update application package and the second update application package, the to-be-analyzed data file is sent to the at least one non-management processor, and the corresponding first update application package is sent to the first non-management processor, which is any one of the at least one non-management processor.

[0047] In the embodiments of the present application, after receiving the remote operation and maintenance upgrade package, the management processor can perform integrity verification on the data in the remote operation and maintenance upgrade package, to ensure that the remote operation and maintenance upgrade package at least includes the to-be-analyzed data file. If the remote operation and maintenance upgrade package does not include the to-be-analyzed data file, the management processor no longer executes the subsequent data writing method process.

[0048] The management processor can copy the to-be-analyzed data file to a working directory, so as to run the to-be-analyzed data file. The management processor also sends the to-be-analyzed data file to the working directory corresponding to the at least one non-management processor, so as to run the to-be-analyzed data file by each non-management processor.

[0049] Step S204: Install the second update application based on the second update application package.

[0050] In the embodiments of the present application, after the management processor sends the corresponding update application package to the one or more non-management processors, the management processor installs the second update application according to a preset installation process, and listens to the installation result of the installation of the corresponding first update application package by each non-management processor.

[0051] After receiving the first update application package sent by the management processor, the one or more non-management processors install the first update application according to a preset installation process.

[0052] Step S205: If the installation completion information sent by each of the at least one non-management processor is received, a whole machine reset instruction is executed, the whole machine reset instruction is used to restart the control device, and the installation completion information is used to indicate that the corresponding first update application has completed installation.

[0053] In the embodiment of the present application, the management processor can listen to and receive the installation completion information sent by each non-management processor when installing the second update application. If the installation completion information sent by each non-management processor is received, and when the second update application has been installed, the whole machine reset instruction is executed to restart the relay protection device.

[0054] The management processor restarts the relay protection device, so that the code in each processor is re-run, i.e., the device is restored to the initial state, so as to write the setting value data in the data file to be parsed. After the management processor restarts the relay protection device, if each processor (including the management processor and the non-management processor) determines that the current relay protection device has been powered on, it is detected whether the data file to be parsed exists in the working directory.

[0055] In the embodiment of the present application, each processor in the relay protection device can determine that the current relay protection device has been powered on through one or more of the power management circuit, the reset circuit, the watchdog circuit, the external signal and the internal clock. For the method of learning through the power management circuit, the power management circuit of the relay protection device can send a power-on signal to each processor when the relay protection device starts or is powered on, and the power-on signal is used to indicate that the relay protection device has been restarted. The power-on signal can be an interrupt signal, which is used to trigger each processor to execute the corresponding start-up code. For the method of learning through the watchdog circuit, the reset circuit of the relay protection device can reset each processor to a known state when the relay protection device starts or is powered on, so that each processor executes the pre-defined start-up code. For the method of learning through the watchdog circuit, the watchdog circuit of the relay protection device periodically sends a signal to each processor, and if each processor does not respond to the signal within a preset time, the reset circuit will be triggered to reset each processor, which can prevent each processor from falling into a dead loop or being unable to run normally when starting or being powered on. For the method of learning through the external signal, the relay protection device can notify each processor that the current device has started or been powered on through an external signal, for example, through some buttons or switches to trigger the start-up process. For the method of learning through the internal clock, the relay protection device can use the internal clock to time the start-up of each processor. The method of learning by each processor in the relay protection device that the current relay protection device has been powered on is not limited in the embodiment of the present application.

[0056] In the embodiment of the present application, if the processor determines that the current relay protection device has been powered on, it is detected whether there is a to-be-resolved data file in the working directory. The corresponding data in the to-be-resolved data file is written into the non-volatile memory, so as to realize the remote automatic upgrade processing of the relay protection device. On the basis of not needing human on-site operation, it is avoided that the self-checking alarm exception is generated after the remote upgrade of the secondary equipment, and the automation level and the intelligent level of the operation and maintenance of the secondary equipment are improved.

[0057] As shown in Figure 3 , another flowchart of a data writing method provided by the embodiment of the present application. If the processor (including the management processor and the non-management processor) detects that there is a to-be-resolved data file in the working directory, the data is written through the following steps:

[0058] Step S301: If it is detected that there is a to-be-resolved data file, the to-be-resolved data file is resolved to obtain a resolved data file. The resolved data file includes fixed value data, insertion segment positioning information of the fixed value data, and fixed value data check code of the fixed value data.

[0059] In the embodiment of the present application, if the processor (including the management processor and the non-management processor) detects that there is a to-be-resolved data file in the working directory, the to-be-resolved data file is resolved to obtain a resolved data file. In the embodiment of the present application, the resolved data file can include fixed value data, insertion segment positioning information of the fixed value data, and fixed value data check code of the fixed value data. Optionally, the resolved data file can also include an insertion segment step, which is used to represent the bit address interval between any two insertion segment sub-positioning information.

[0060] The insertion segment positioning information can include one or more insertion segment sub-positioning information, and the fixed value data can include one or more fixed value sub-data. The insertion segment sub-positioning information and the fixed value sub-data correspond to each other in one-to-one manner. The insertion segment positioning information can be used to represent the insertion position of one or more fixed value sub-data in the non-volatile memory, and the insertion segment step can be used to represent the distance between two insertion positions.

[0061] For example, as shown in Figure 4 , a non-volatile memory diagram of a data writing method provided by the embodiment of the present application. It includes four non-volatile memories (first non-volatile memory, second non-volatile memory, third non-volatile memory and fourth non-volatile memory), which are connected with MCPU, PCPU, BCPU and SCOM through internal buses. As shown in Figure 4 , the insertion segment positioning information of the fixed value data is used to represent the positions of the plurality of "insertion segment" arrows in the non-volatile memory. The insertion segment step is used to represent the bit address interval between any two "insertion segment" arrows.

[0062] For example, for parsing the fixed value data contained in the data file, if the voltage of the line protection device is 220 kV, the current running fixed value area information of the field device is 01, the fixed value code is 100 (i.e. index, i.e. the serial number of the fixed value data is 100), the positive code value is 0x000000AA, and the inverse code value is 0xFFFFFF55, the content of the fixed value data can be: 00007D805501011F03E802D07CC028600064000000AAFFFFFF55. The inverse code value is used to check the reading result.

[0063] Step S302: reading the stored data in the first memory and temporarily storing the stored data in the first memory segment in the second memory, the stored data including the first check code, the first check code being used to verify the stored data, the stored data being the data required for the normal operation of the control device, the first memory being a non-volatile memory, and the second memory being a volatile memory.

[0064] For example, referring to Figure 1 , the volatile memory can be a memory, and the plurality of processors can be connected with the memory and temporarily store data through the memory.

[0065] In the embodiment of the application, to avoid changing the data (stored data) fixed in the non-volatile memory in the process of writing the fixed value data, the processor can first temporarily store the data fixed in the non-volatile memory in the memory (second memory). The data fixed in the non-volatile memory of the relay protection device can include: device parameters, fixed value data, protection logic, event record and self-check data. The non-volatile memory is used to ensure that the fixed data will not be lost even after the device is powered off, so as to ensure the normal operation and maintenance of the relay protection device.

[0066] For example, referring to Figure 4 , the stored data can be the data in each rectangular box of the first non-volatile memory, the second non-volatile memory, the third non-volatile memory and the fourth non-volatile memory, including: Set_Sys (system fixed value), Set (protection fixed value) (a plurality of protection fixed value areas corresponding to the first non-volatile memory of the MCPU), Parameter (device parameters), SoftSet (soft press plate), TrigCfg (trip configuration), TLVPara (TLV parameters), SetCrc (fixed value crc), ParameterCrc (device parameter crc), SoftSetCrc (soft press plate crc), TrigCfgCrc (trip configuration crc), TLVParaCrc (TLV parameter crc) and Others (other settings).

[0067] In the embodiment, the processor reads the stored data in the first memory, and stores the stored data in the second memory, and the data arrangement order of the stored data in the second memory is the same as that in the first memory.

[0068] For example, as shown in Figure 5 , a schematic diagram of a volatile memory provided by a data writing method in the embodiment is shown. As shown in Figure 5 , the processor stores the stored data in the first non-volatile memory in the second memory. Figure 4 , the data arrangement order of the stored data in the second memory is the same as that in the first non-volatile memory.

[0069] Step S303: inserting the constant data into the first address segment in the second memory according to the insertion segment positioning information.

[0070] In the embodiment, the processor can calculate at least one insertion address of at least one constant sub-data in the second memory according to at least one insertion segment sub-positioning information and an insertion segment step, the at least one constant sub-data corresponds to the at least one insertion address one by one, and the at least one insertion address is an address in the first address segment. The processor inserts a first constant sub-data into a first insertion address in the second memory, the first constant sub-data is data in the at least one constant sub-data, and the first insertion address is an address corresponding to the first constant sub-data in the at least one insertion address.

[0071] Since the processor directly writes the constant data into the memory, the data (stored data) in the memory is changed. In the technical solution provided by the embodiment, when the processor inserts the first constant sub-data into the first insertion address in the second memory, the constant sub-data can be inserted by copying data. For example, as shown in Figure 5 , after determining the first insertion address in the plurality of insertion addresses, the processor can copy the data before the first insertion address in the stored data to the free bit address in the second memory, and then insert the first constant sub-data into the position of the first insertion address. As shown in Figure 5 , the processor can copy the data after the first insertion address and before the second insertion address to the second memory, and then insert the second constant sub-data into the position of the second insertion address, and so on until all the constant sub-data are inserted. As shown in Figure 5 , the constant sub-data and the stored data are alternately stored in the second memory.

[0072] Step S304: Calculate a second check code based on the fixed value data check code and the stored data, and modify the first check code in the second memory into the second check code, where the second check code is used to verify the stored data and the fixed value data.

[0073] In an embodiment of the present application, in order to ensure the correctness and reliability during operation, the relay protection device can perform local board verification and inter-board verification after remote upgrade processing. If the data in the update verification code is consistent with the data in the relay protection device firmware (including non-volatile memory), the relay protection device can determine that the data in the firmware has not been illegally tampered with or damaged. If the data in the update verification code is inconsistent with the data in the relay protection device firmware, the relay protection device can determine that there may be a problem with the data in the firmware. The relay protection device will generate an abnormal alarm. The processor of the relay protection device calculates the update verification code through the fixed value data verification code and the stored data, which can ensure that the update verification code is consistent with the data in the relay protection device firmware, avoiding abnormal alarms in the relay protection device. This ensures the normal operation of the relay protection device.

[0074] For example, see Figure 5 In (a), after the processor calculates the second check code from the fixed value data check code and the stored data, it can modify the first check code of the bit address indicated by the "modify" arrow in the second memory to the second check code.

[0075] Step S305: Read the stored data and the fixed value data in the second memory, and write the stored data and the fixed value data into the first memory.

[0076] After the processor modifies the first check code in the second memory into the second check code, it can rewrite the stored data and fixed value data temporarily stored in the second memory into the first memory to ensure the normal operation of the relay protection device. Figure 5 As shown, the stored data and the fixed value data in the second memory are alternately stored in the second memory. After the stored data and the fixed value data in the second memory are rewritten into the first memory, the arrangement order of the stored data and the fixed value data in the first memory is the same as the arrangement order in the second memory.

[0077] In an embodiment of the present application, after the processor rewrites the stored data and constant value data alternately stored in the second memory into the first memory, it can delete the parsed data file to avoid the relay protection device repeatedly updating and reading the parsed data file, thereby causing a control device operation failure.

[0078] In the technical scheme provided by the embodiment, the processor can parse the to-be-parsed data file to obtain a parsed data file after detecting the to-be-parsed data file, and temporarily store the stored data in the nonvolatile memory into the volatile memory. Then, according to the insertion segment positioning information in the parsed data file, the fixed value data in the parsed data file is inserted into the volatile memory, and a second check code is calculated according to the fixed value data and the stored data, and the second check code is updated to the volatile memory. Finally, the stored data and the fixed value data are re-written in the nonvolatile memory. The situation that the stored data in the nonvolatile memory is changed when the fixed value data is written into the nonvolatile memory can be avoided. The second check code contains data information corresponding to the fixed value data and the stored data, which can avoid abnormal alarm of the control device when performing board check or board check, thereby realizing remote upgrading of the control device, saving time and manpower consumed by remote upgrading of the control device, simplifying the remote upgrading process of the control device, and improving the automation level and intelligent level of the remote upgrading of the control device.
