Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.
Detailed description of the preferred embodiment
As shown in fig. 1, an embodiment of the present invention provides a method for implementing an intelligent component at a process level of an intelligent substation, including the following steps.
A setup step S101:
and establishing a multi-task system architecture according to the functional requirements and the working process of the process layer intelligent assembly.
Analysis step S102:
analyzing a CID file exported by the IED tool, and generating a configinfo. The configlnfo.
Specifically, a CID file derived by an IED configuration tool can be analyzed in a DOM mode, the whole CID file of a target intelligent assembly is read into a memory to generate an image of a tree structure, and nodes with parent-child relationships are generated; then, establishing information template classes of each element according to the schema file, and then establishing one-to-one correspondence between each node on the DOM tree and the corresponding template class; obtaining information such as SV, GOOSE number, destination MAC address, data set, mapping relation and the like issued by the intelligent assembly of the process layer according to keywords such as communication, dataset, input and the like to obtain functional function definitions of each item of the intelligent assembly; assigning the extracted information to a predefined variable and Table, generating and storing a configinfo.
The intelligent components can be in various types, and the intelligent components in the same type are different due to different working modes and different functional requirements. For example, the merging unit has input terminals connected in current-voltage analog quantity mode and collector digital quantity mode, and output terminals connected in Ethernet and FT3 mode, and the output terminals have different numbers. In order to implement different types of intelligent components, corresponding adjustments in the implementation of the program must be made. If different functions are realized in the executable file, enumeration is required according to different values of variables, so that on one hand, code space is increased, program code reading is not utilized, and on the other hand, inconvenience is brought to program upgrading and maintenance.
A defining step S103:
decomposing and abstracting each functional module of the intelligent assembly by using a configlnfo. The functional modules correspond to the workflow one by one; for intelligent components of different types or intelligent components of the same type with different functions, the intelligent components can be decomposed and abstracted into a combination of a plurality of functional modules, and a shared data structure and a function calling interface are defined for each functional module. Preferably, the defining step S103 may further include: if the definition of each function module of the intelligent component is different from that of a certain function, the function is further defined in a configinfo. This has the advantage that, for the case that the same function is used for each function module of the intelligent component, and the definition of the same function is different, it may be adopted to further define the function in the configinfo. Meanwhile, data structures such as readdata, writedata and the like are defined in the executable file, and data sharing and function mutual calling are realized by utilizing the Lua and C interaction technology, so that the condition that every function is ambiguous cannot be ensured to be defined, and ambiguity is avoided.
Compiling step S104:
decomposing the multitask and workflow requirements of the intelligent assembly, creating an interrupt service program, and distributing task priorities;
compiling and connecting source codes containing all functional modules and workflows thereof and Lua source codes to generate executable files; alternatively, the first and second electrodes may be,
compiling and connecting source codes comprising all functional modules and workflows thereof and a target system library generated by Lua source codes to generate executable files;
the executable file is used for matching with a configinfo.
Firstly, establishing a multi-task system architecture according to the functional requirements and the working process of the process layer intelligent assembly; decomposing and abstracting various intelligent assembly function modules, and defining a shared data structure and a function calling interface; and compiling and connecting a source code comprising an intelligent component complete module and a workflow and a target system library generated by a Lua source code or the Lua source code to generate an executable file, and matching with a configinfo. According to the embodiment of the invention, the CID file and the device function configuration information required by the operation of the intelligent component are integrated into one file through the Lua technology, so that the process layer intelligent components with different types of functions are realized, the product applicability is enhanced, the development cost is reduced, and the management and the operation maintenance are convenient.
Preferably, the defining step S103 may specifically be:
compiling Lua source codes according to the running environment; in the embodiment of the invention, the operating environment can be vxworks and/or Linux.
Generating a Lua compiler and a Lua translator in a library file form, linking the Lua compiler and the Lua translator into a target program, and analyzing and executing a configinfo. Or directly adding the Lua source code into the project engineering file to generate a target executable file, and executing a configinfo.
According to the hardware configuration information of the intelligent assembly, acquiring various function definitions, port configurations and a working process of the intelligent assembly, decomposing and abstracting various function modules of the intelligent assembly, and defining a shared data structure and Lua and C interaction interfaces of each function module;
defining a function in a configinfo. The function is used for realizing various functions of the intelligent assembly.
Preferably, before parsing and executing the configlnfo. And (4) carrying out lexical and syntactic check on the configlnfo. Lua script file by using a Lua compiler in the target program, and carrying out alarm prompt if the file is lost, damaged or has errors. The method has the advantages that the situations that the lexical method and the grammar in the configinfo. Preferably, after the device is powered on, a Lua compiler in the object program is used for lexical and syntactic checking.
Preferably, the defining step S103 may further include: and reasonably distributing the hardware space of each functional module by combining the hardware characteristics of the intelligent assembly. The advantage of doing so is that the occupied space can be rationally distributed according to the hardware characteristics of the intelligent components. For example, in the embodiment of the present invention, a hardware architecture may adopt an ARM + DSP + FPGA combination, where the ARM completes interface display, external communication, and compiling, interpreting, and executing of a configinfo.
The embodiment of the present invention does not limit each function of the intelligent component, and preferably, each function of the intelligent component includes one or more of initialization, data reading, synchronous interpolation, SV/GOOSE encoding and decoding, ethernet data transmission, and synchronous time keeping. The executable file is used for matching with a configinfo. The power-on initialization mainly completes hardware initialization, configinfo. The interrupt service program mainly completes clock synchronization, real-time data reading (receiving real-time sampling data) writing (sending data updating); the interrupt-level task mainly completes data filtering, interpolation synchronization and coding and decoding of SV, GOOSE and FT3 data; the general task is mainly to complete human-computer interaction and external communication.
In addition to completing conventional hardware initialization, power-on initialization involves three key techniques.
Lua script file is compiled and interpreted. To achieve this goal, the lua source code may be added at the time of creating the executable project file, or the lua library (including the compiler and interpreter) of the target runtime environment may be added at the time of linking;
secondly, FPGA online programming. Firstly, setting an FPGA to be in an online programming working mode through a hardware selection line; compiling the FPGA target working program into a c file, such as fpagcode.c, and adding the c file into an executable file engineering file; thirdly, allocating an FPGA online programming IO port line and a configuration address in an FPGA configuration code corresponding to the executable file, downloading fpgacode.c to the FPGA by the executable code during power-on execution, detecting the downloading state in real time during the downloading process, giving an alarm if an error occurs, and resetting the FPGA after the downloading is finished so as to enable the FPGA to be switched to a working state;
and thirdly, DSP online programming. Firstly, the DSP writes a target working program according to function distribution, and generates a binary file after compiling and linking; and secondly, preparing a DSP online programming program (equivalent to a bootloader) as a program which is firstly run when being electrified. After power-on, serial port data is monitored, an upgrade waiting state is entered, the communication finishes the receiving and storing of the target program, and after the programming is successful, the main program is entered for running.
The interrupt service program mainly completes clock synchronization and real-time data reading and writing. The clock synchronization, the time keeping, the A/D data sampling and the receiving and sending of various protocol data can be completed by the FPGA, the precise time sequence control capability and the abundant characteristics of the peripheral programmable IO interface are fully utilized, and an RAM ping-pong mechanism is adopted for realizing the read-write switching of the data area. The FPGA writes various received real-time data into a pre-allocated storage space, the DSP reads the real-time data in a data bus mode and transfers the real-time data to the rear-end interrupt task for processing, the ARM writes the coded real-time data to be sent into the FPGA through the bus in advance according to the storage space allocated by the hardware port, and the coded real-time data is sent out according to the time sequence requirement after being read by the FPGA.
The interrupt-level task mainly completes data filtering, interpolation synchronization, and coding and decoding of SV, GOOSE and FT3 data, and is completed by utilizing the strong capability of DSP for processing various data. For a merging unit accessed by analog quantity, synchronous sampling of current and voltage electric quantity is completed through an A/D synchronous trigger conversion technology, and the DSP performs digital filtering processing on the read real-time sampling data and converts corresponding digital quantity according to SV target protocol and inspection precision requirements. For a digital access merging unit, whether the merging unit is collector or Ethernet data, a DSP (digital signal processor) needs to perform protocol decoding to obtain original real-time data, and for a current and voltage sampling value, further interpolation synchronous secondary resampling is needed. And the ARM carries out SV and GOOSE coding according to target protocol information obtained by analyzing the configinfo.
The general task is mainly to complete human-computer interaction and external communication. The man-machine interaction is not different from the man-machine interaction of a general device except that whether the liquid crystal module drive is started or not is determined according to configinfo.
The embodiment of the invention is based on modular design, each function corresponds to an abstract model (a data structure and a function), and when the functions are expanded, the corresponding abstract model is firstly established, the data types, the interaction and the organization forms in the models are then decomposed, and finally the corresponding functional subfunctions are compiled. Therefore, the subsequent function expansion and upgrading are essentially the increase and optimization of the number of modules, and the establishment of an abstract model of a new functional module can be easily realized.
In the first embodiment, an implementation method of an intelligent substation process level intelligent component is provided, and correspondingly, an implementation device of the intelligent substation process level intelligent component is also provided. Since the apparatus embodiments are substantially similar to the method embodiments, they are described in a relatively simple manner, and reference may be made to some of the descriptions of the method embodiments for relevant points.
