[0002] As a key device in the smart grid, smart meters are responsible for recording and storing various data, including meter operation configuration data, meter performance parameter data, power data, etc. These data need to be stably and reliably recorded in eeprom (non-volatile memory) to ensure that the data will not be lost when the meter loses power.

[0003] The existing event recording and freezing recording schemes have the following main defects: lack of unified planning. In the design phase, the address space is not systematically allocated, resulting in frequent address modifications during subsequent function expansion. Scalability is not considered, and sufficient storage space is not reserved for future functions, which can easily lead to insufficient addresses or chip replacement, address overlap, and different functional modules are assigned to the same address, resulting in data conflicts and storage errors, which seriously affect system stability. Summary of the invention

[0035] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the specific embodiments of the accompanying drawings.

[0036] Example 1

[0037] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with general skills in the field to which the present invention belongs. "Including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0038] In view of the problems existing in the existing technology, such as Figure 1 and Figure 2 As shown, the present application proposes a smart meter storage allocation method, comprising the steps of:

[0039] S101, obtaining different modules in the smart meter;

[0040] S102, allocating locations in the memory according to the importance and variation degree of data of different modules;

[0041] S103, constructing a total structure through the memory, and constructing module placeholder structures for different modules respectively;

[0042] S104, whenever a new module is added, a new placeholder structure is added to the overall structure.

[0043] Specifically, the functional modules of the smart meter are identified to provide basic data for storage allocation. The locations of the modules are allocated in the memory according to the importance and degree of variation of the data. This optimizes the space utilization of the memory, improves the reliability and access efficiency of the data, and constructs an overall structure through the memory. Different modules construct module placeholder structures respectively to achieve modular storage design, which is convenient for management and expansion. Whenever a new module is added, the new placeholder structure is added to the overall structure to support dynamic expansion and reduce maintenance and modification costs.

[0044] In some specific embodiments, the different modules include at least power, instantaneous quantity, TOU, freeze, event, demand, display, and communication.

[0045] Specifically, the power module

[0053] Degree of mutation: High (frequent changes);

[0057] Data importance: high (critical data for billing);

[0058] Degree of mutation: medium (updated in time);

[0066] Data importance: Moderate (diagnostic use);

[0071] Data importance: Medium;

[0072] Degree of mutation: medium (statistical periodic changes);

[0073] Allocation strategy: close to the instantaneous quantity module to facilitate real-time data association;

[0074] Display Module

[0075] Function: Provide visual data of the current status of the meter (such as power consumption and voltage);

[0076] Data importance: low (for interface display);

[0077] Degree of mutation: High (updated in real time);

[0078] Allocation strategy: rear area, lower priority;

[0079] Communication Module

[0080] Function: Store configuration parameters for communicating with external devices (such as baud rate, protocol);

[0081] Data importance: medium (system function dependency);

[0082] Degree of mutation: high (dynamic modification);

[0083] Allocation strategy: tail area, easy for dynamic adjustment.

[0084] In some specific embodiments, data of different modules with high importance and low variance are placed at the front.

[0085] Specifically, in the TOU module, the RTC plug-in is a circuit that can generate time and date information such as hours, minutes, seconds, and calendars. The RTC can transmit time information to other modules to ensure the time synchronization of the entire system. When designing a program, time is one of the most important factors in maintaining the normal operation of the entire program framework, so the TOU module is placed at the head in the eeprom allocation;

[0086] The electric energy module is a key component for realizing the electric energy measurement, recording and billing functions. When the electric energy meter is in normal operation, when the electric energy accumulates to a certain degree, the electric energy meter will store the electric energy in the eeprom. The electric energy data belongs to the core key data of the electric energy meter. When other modules change the data, the electric energy data should not be affected. Therefore, the electric energy data is placed in the second position allocated by the eeprom, which can effectively avoid the occurrence of errors.

[0087] Communication module. In actual applications, the client may need to change the communication parameters according to different application scenarios. This parameter is a variable parameter, so it should be positioned at the back when eeprom is arranged.

[0088] In some specific embodiments, allocating locations in the memory according to the importance and variance of data of different modules includes:

[0089] Determine the address positions of different modules in the memory to determine different offset addresses, and obtain specific addresses of different modules by adding the memory and the offset address.

[0090] Specifically, define the starting address and available storage range of the memory (such as the starting address EE_START_ADDR and size EE_SIZE of eeprom), determine the priority according to the importance and degree of variation of the module list (such as power, instantaneous quantity, TOU, etc.), assign the modules with high data importance and low degree of variation to the front address (such as power and TOU modules), and assign the modules with high degree of data variation or low importance to the back address (such as communication modules);

[0091] The starting address of each module is: module starting address = memory starting address + offset address, the offset address is the end address of the previous module storage area plus the safety interval, the memory base address and the offset address are added to obtain the specific storage address range of each module. In some embodiments, the formula is as follows:

[0092] Module start address = EE_START_ADDR + module offset;

[0093] The module address is calculated through a formula to avoid manual allocation errors and conflicts. When adding a new module, you only need to add the offset address at the end without replanning the entire storage area. The core module is placed in the front to reduce the interference of volatile modules on key data.

[0094] In some specific embodiments, data of different modules with high importance and low mutation degree are placed in the front position, including:

[0095] The weights of different modules are added according to their importance and degree of variation, and modules with high weights are placed at the front of the memory.

[0096] Specifically, in some embodiments, the weight factor is defined as:

[0097] Importance factor (W_imp): quantifies the importance of module data, assuming the value range is 1-10, the higher the value, the more important it is;

[0098] Mutation degree factor (W_var): quantifies the mutation frequency of module data. The value range is 1-10, and the lower the value, the lower the mutation degree.

[0099] Comprehensive weight formula:

[0100] ;

[0101] W_total is the comprehensive weight, which is determined by the importance of the module and the degree of mutation. The modules are sorted from high to low according to the comprehensive weight value, and the storage locations are allocated in order of weight. Modules with high weights are preferentially allocated to the front positions of the storage.

[0102] In some specific embodiments, Figure 3 and Figure 4 The module placeholder structure includes a parameter placeholder structure, and the parameter placeholder structure includes multiple parameter structures. The address offset calculation of different parameter structures is performed through the overall structure.

[0103] Specifically, each module occupies a storage area through a placeholder structure, and the placeholder structure contains one or more parameter placeholder structures. Each parameter placeholder structure defines specific parameter data and is stored in a predetermined memory location. The starting address of the module placeholder structure is determined by the offset address of the existing module in the overall structure. The offset of the parameter structure is calculated based on the order of the parameter placeholder structure in the module to calculate its specific address in the memory.

[0104] In some specific embodiments, Figure 3 and Figure 4 , whenever a new parameter is added, add the parameter structure of the new parameter to a different module placeholder structure.

[0105] Specifically, when adding a parameter structure to a module, you only need to add it to the corresponding parameter placeholder structure without considering address allocation. Whenever you need to add new parameters to a module, you can do so by dynamically expanding the parameter structure in the module placeholder structure. This design requires us to be able to flexibly allocate new storage space for each module.

[0106] In some specific embodiments, Figure 5 , in combination with the figure, an embodiment of the present invention provides a smart meter storage allocation device, including:

[0107] An acquisition unit 301 is used to acquire different modules in a smart meter;

[0108] An allocation unit 302, configured to allocate locations in the memory according to the importance and variation of data of different modules;

[0109] A construction unit 303 is used to construct a total structure through a memory, and different modules respectively construct module placeholder structures;

[0110] The adding unit 304 is used to add a new placeholder structure into the overall structure whenever a new module is added.
