[0026] State Grid 698 Protocol: It is an important specification for electric energy meter communication in China's power industry. This protocol is an object-oriented communication protocol, widely used in data exchange between master station and acquisition terminal, acquisition terminal and electric energy meter, master station and electric energy meter. This protocol specifies the communication protocol, data format, transmission method, etc. between electric energy meter and acquisition equipment, ensuring the stable and accurate transmission of electric energy data.

[0027] APDU: Application Protocol Data Unit, is a protocol for communication between smart cards and card readers. APDU defines the data format and rules transmitted in the interaction, allowing the card reader to send instructions and receive responses.

[0028] The present invention provides an electric energy meter protocol deframing method, which designs a universal framing and deframing function for data types, combines configuration parameters and linked list search technology, has the advantages of code space saving, easy maintenance, efficient expansion, etc., solves the problem of repeated writing of deframing and framing functions in the prior art, resulting in large code volume, high maintenance difficulty, low efficiency and waste of resources. The electric energy meter protocol deframing method is suitable for an electric energy meter protocol deframing device, which can be an electronic device. The electric energy meter protocol deframing method in the embodiment of the present invention can be applied to a variety of scenarios, such as electric energy meter protocol deframing, etc.

[0029] See also Figure 1 , an embodiment of the present invention provides a method for de-framing an electric energy meter protocol, which is applicable to electronic equipment.

[0030] In the following method embodiments, for ease of description, the execution subject of each step of the method is taken as an electronic device as an example for illustration, but this does not constitute a specific limitation.

[0031] like Figure 1 As shown, the method may include the following steps:

[0032] Step 110, parse the application protocol data unit of the State Grid 698 protocol to obtain the service type and object identifier, and perform a binary search on the object identifier to obtain the object configuration information.

[0033] Specifically, an APDU (Application Protocol Data Unit) is parsed from the received data packet. The APDU includes a service type (such as a read object, a write object, etc.) and an object identifier (usually an ID or index for uniquely identifying an object).

[0034] Furthermore, a binary search algorithm is used to search for the object identifier in the existing object configuration information table. The object configuration information table is a data structure containing all object configuration information, usually stored in some form (such as an array, hash table, etc.). The binary search algorithm quickly locates the object configuration information by continuously halving the search interval until the corresponding object identifier is found or it is determined that the object does not exist.

[0035] Step 130, obtaining the member number limit, operation authority and multiple sub-member information of the object according to the object configuration information, and reading the corresponding sub-member data information according to each sub-member information.

[0036] Specifically, the member number limit (such as the maximum number of members), operation permissions (such as read-only, write-only, read-write, etc.) and sub-member information list of the object are extracted from the object configuration information.

[0037] Furthermore, the sub-member information list is traversed, and for each sub-member, the corresponding sub-member data is read according to its information (such as operation mode, data source length, RAM address, EEPROM address, etc.), and the RAM address or EEPROM address of the sub-member information is used to read the data from the corresponding storage location.

[0038] Step 150: If the service type is a read object, framing is performed according to the data types and lengths of the plurality of sub-member data information.

[0039] Specifically, first confirm that the service type is a read object, then traverse all sub-member data information, and frame the read data according to the format of the State Grid 698 protocol based on the data type and length of each sub-member. During the framing process, it is necessary to ensure that the data sequence, format, checksum, etc. meet the protocol requirements.

[0040] Step 170: If the service type is to write an object, deframe the data according to the data type and length of the data information of the plurality of sub-members and write the data into the corresponding data source location and save it.

[0041] Specifically, first confirm that the service type is a write object, then parse the data to be written from the received data packet, and deframe it according to the format of the State Grid 698 protocol. During the deframing process, it is necessary to verify whether the integrity and format of the data meet the protocol requirements. According to the RAM address or EEPROM address of the sub-member information, the deframed data is written to the corresponding storage location. If there are default values ​​or fields that require special processing, they should also be processed accordingly before writing. After writing the data, perform some additional save operations according to system requirements, such as updating the data in the EEPROM, generating log files, etc.

[0042] In a possible implementation, the object configuration information is a structure, and the object configuration information includes the maximum index of the object, read and write permissions, special tags, data types, and child member information.

[0043] In one possible implementation, the sub-member information is a structure, which includes the object's operation mode, data source length, RAM address, EEPROM address, default value address, sub-member data offset, sub-member data length, number of identical sub-members, sub-member data information and next-level sub-member information.

[0044] In a possible implementation, the sub-member data information is a structure or a structure array, and the sub-member data information includes the data type of the sub-member, the data length, the number of next-level sub-members, and next-level sub-member information.

[0045] Through the above process, the present invention first obtains the service type and object identifier according to the application protocol data unit of the State Grid 698 protocol, performs a binary search on the object identifier to obtain the object configuration information, and then obtains the member number limit, operation authority and multiple sub-member information of the object according to the object configuration information, reads the corresponding sub-member data information according to each sub-member information, and if the service type is a read object, frames are formed according to the data type and length of the multiple sub-member data information; if the service type is a write object, frames are deframed according to the data type and length of the multiple sub-member data information and written into the corresponding data source location and saved. By designing a general framing and deframing function for the data type, combined with configuration parameters and linked list search technology, it has the advantages of code space saving, easy maintenance, efficient expansion, etc., and is an innovative framing and deframing implementation method, thereby effectively solving the problems of large code volume, high maintenance difficulty, low efficiency and resource waste caused by repeated writing of deframing and framing functions in the prior art.

[0046] In one application scenario, Figure 2 A flowchart of reading objects in an energy meter protocol de-framing method is shown. Figure 3 It shows a flowchart of writing objects. Figure 4 The schematic diagram of the process of sub-member data information framing is shown. Figure 5 A schematic diagram of the process of deframing sub-member data information is shown;.

[0047] like Figure 2 As shown, first determine whether the service type is read. If so, give the protocol object to find the configuration information, then obtain the first sub-member information according to the configuration information, and then traverse each sub-member: obtain the original data according to the sub-member data source information until the data of all sub-members are obtained, find the configuration information based on the protocol object, and then obtain the first sub-member information according to the configuration information, and then traverse each sub-member: frame according to the framing information of the sub-member information until all sub-members are framed, and then end the reading object.

[0048] like Figure 3 As shown, the child member data information is a structure array. After the first grandchild member is framed, the next grandchild member information will continue to be read until the last grandchild member. The information of each grandchild class member is obtained by traversing the linked list for framing.

[0049] like Figure 4As shown, first determine whether the service type is write. If so, give the protocol object to find the configuration information, then get the first sub-member information according to the configuration information, and then traverse each sub-member: parse the original data according to the sub-member data information of the sub-member information until the original data of all sub-members are obtained, find the configuration information based on the protocol object, and then get the first sub-member information according to the configuration information, and then traverse each sub-member: write the data source location according to the data source information of the sub-member information and save it until the data of all sub-members are written and saved, and then end the write object.

[0050] like Figure 5 As shown, the child member data information is a structure array. After the first grandchild member is deframed, the next grandchild member information will continue to be read until the last grandchild member. The information of each grandchild class member is obtained by traversing the linked list for deframing.

[0051] Through the above process, the embodiment of the present invention effectively solves the problem of large code volume and difficult maintenance in traditional object-oriented design by designing a general framing and deframing function for data types and combining configuration parameters and linked list search technology. This solution has the advantages of code space saving, easy maintenance, and efficient expansion, and is an innovative framing and deframing implementation method.
