Description

Technical Field

[0001] This disclosure relates to the field of computer communication technology, and in particular to a data processing method, system and apparatus. Background Technology

[0002] With the rapid development of IoT technology, a large number of IoT terminal devices, such as environmental monitoring sensors, smart home appliances, and industrial automation equipment, are widely deployed in various scenarios. These devices typically need to periodically report the operational data or environmental parameters they collect to a remote cloud-based IoT platform via wireless communication networks (such as 4G, 5G, NB-IoT, etc.) for centralized monitoring, data analysis, and fault diagnosis.

[0003] In typical IoT data reporting applications, the terminal device and the platform use a client-server communication model. Since terminal devices are usually resource-constrained (e.g., weak computing power, small memory), the communication protocol between them is often designed to be relatively simple, such as using a register-based message format similar to the Modbus protocol. This protocol has a clear structure, low overhead, and is easy to implement in embedded systems.

[0004] However, the stability of the wireless communication link is a key factor affecting the reliability of data reporting. Due to signal interference, network congestion, or equipment movement, the network connection between the terminal device and the platform may be temporarily interrupted, i.e., "dropped." During the period when the terminal device is offline, its internal operational data acquisition function usually continues to operate normally, but the generated operational data cannot be sent to the platform in real time. Existing simple communication protocols generally do not have mechanisms to handle long-term network interruptions. When the network connection is restored and the terminal device comes back online, a large amount of operational data generated during the offline period will be lost, resulting in gaps in the platform's historical data records. This is a fatal flaw for applications that require ensuring data continuity and integrity (such as cold chain transportation monitoring, production safety early warning, etc.), making it impossible for managers to effectively trace and analyze the operational status of the terminal device during the offline period, thus creating potential security risks. Summary of the Invention

[0005] This disclosure provides a data processing method, system, and apparatus, which aims to solve the technical problem of loss and untraceability of historical data of Internet of Things (IoT) devices due to network interruption.

[0006] The technical solution disclosed herein is implemented as follows:

[0007] In a first aspect, this disclosure provides a data processing method applied to a terminal device. The data processing method includes: storing the current running data and current timestamp generated by the terminal device as a historical data record when the network connection between the terminal device and the platform is offline; generating a historical data message based on at least one historical data record when the network connection is restored to online status; the historical data message includes a first starting register address, a register count field, and a data area; the first starting register address is used to indicate a preset address for the historical data message including the timestamp; the data area includes at least one historical data record; the value of the register count field represents the total number of registers occupied by all historical data records contained in the data area; and sending the historical data message to the platform.

[0008] Secondly, this disclosure provides a data processing method applied to a platform. The data processing method includes: receiving a data packet sent by a terminal device, the data packet including a starting register address, a register count field, and a data area; when the starting register address is a first starting register address, determining the number of historical data records included in the data packet based on the value of the register count field and the register length of a preset single historical data record, the first starting register address being used to indicate that the data packet is a historical data packet including a preset address; cyclically parsing the timestamps and running data of the specified number of historical data records from the data area, and storing the running data based on the timestamps.

[0009] Thirdly, this disclosure provides a data processing apparatus applied to a terminal device. The data processing apparatus includes: a storage section for storing the current running data and current timestamp generated by the terminal device as a historical data record when the network connection between the terminal device and the platform is offline; a processing section for generating a historical data message based on at least one historical data record when the network connection is restored to online status. The historical data message includes a first starting register address, a register count field, and a data area. The first starting register address is used to indicate a preset address for the historical data message including a timestamp. The data area includes at least one historical data record, and the value of the register count field represents the total number of registers occupied by all historical data records contained in the data area; and a sending section for sending the historical data message to the platform.

[0010] Fourthly, this disclosure provides a data processing apparatus applied to a platform. The data processing apparatus includes: a receiving section for receiving data packets sent by a terminal device, the data packets including a starting register address, a register count field, and a data area; a determining section for determining the number of historical data records included in the data packet based on the value of the register count field and a preset register length for a single historical data record, provided that the starting register address is a first starting register address; the first starting register address for indicating that the data packet is a historical data packet including a preset address; a parsing section for cyclically parsing the timestamps and running data of the specified number of historical data records from the data area; and a storage section for storing the running data based on the timestamps.

[0011] Fifthly, this disclosure provides an electronic device including a processor, a memory, and a program or instructions stored in the memory and executable on the processor, wherein the program or instructions, when executed by the processor, implement the steps of the data processing method as described in the first and / or second aspects.

[0012] In a sixth aspect, this disclosure provides a computer-readable storage medium on which a program or instructions are stored, which, when executed by a processor, implement the steps of the data processing method as described in the first and / or second aspects.

[0013] In a seventh aspect, this disclosure provides a computer program product, wherein the computer program product includes a computer program or instructions, which, when executed on a processor, cause the processor to execute the computer program or instructions to implement the steps of the data processing method as described in the first and / or second aspects.

[0014] Eighthly, this disclosure provides a chip including a processor and a communication interface coupled to the processor, the processor being used to run programs or instructions to implement the steps of the data processing methods as described in the first and / or second aspects.

[0015] Ninthly, this disclosure provides a data processing system, which includes: at least one terminal device, a platform, and a communication network, wherein the at least one terminal device and the platform communicate through the communication network;

[0016] A terminal device is configured to, when the network connection between the terminal device and the platform is offline, store the current running data and current timestamp generated by the terminal device as a historical data record; and, when the network connection is restored to online, generate a historical data packet based on at least one historical data record, the historical data packet including a first starting register address, a register count field, and a data area, wherein the first starting register address is used to indicate a preset address including the timestamp of the historical data packet, the data area includes at least one historical data record, and the value of the register count field represents the total number of registers occupied by all historical data records contained in the data area; and send the historical data packet to the platform.

[0017] The platform is configured to receive data packets sent by terminal devices. The data packets include a starting register address, a register count field, and a data area. When the starting register address is a first starting register address, the platform determines the number of historical data records included in the data packet based on the value of the register count field and the preset register length of a single historical data record. The first starting register address is used to indicate that the data packet is a historical data packet with a preset address including a timestamp. The platform also cyclically parses the timestamps and running data of the specified number of historical data records from the data area and stores the running data based on the timestamps.

[0018] This disclosure provides a data processing method, system, and apparatus. By caching timestamped runtime data when a terminal device is offline, and then retransmitting a historical data packet marked with a specific starting register address after the device reconnects, the platform can easily distinguish between real-time and historical data by simply determining this address value, and accurately recover the historical data using the timestamp carried in the packet. This solution solves the problem of data loss and untraceability caused by network interruptions without changing the original packet structure or adding additional signaling fields, ensuring data integrity, and greatly simplifying the implementation logic of the breakpoint resume function.

[0031] The technical solutions in the embodiments of this disclosure will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure are within the scope of protection of this disclosure.

[0032] Please see Figure 1 , Figure 1 This is a schematic diagram of the architecture of a data processing system 10 provided in an embodiment of this application. The data processing system 10 aims to provide a reliable IoT data acquisition and monitoring solution, particularly suitable for scenarios with unstable network environments.

[0033] The data processing system 10 may include at least one terminal device 110, a communication network 120, and a platform 130.

[0034] In this embodiment, terminal device 110 can be a temperature control device, such as a smart temperature controller for cold chain logistics vehicles, fresh food supermarket freezers, or pharmaceutical warehouses. Of course, terminal device 110 is not limited to temperature control devices; it can be any IoT device that needs to periodically report data, such as a smart meter or environmental monitoring station. The core function of terminal device 110 is to collect one or more of its own operating parameters and send these parameters to platform 130 via communication network 120.

[0035] Specifically, the terminal device 110 typically integrates hardware such as sensors, a processor, memory, a communication module, and a real-time clock. The processor, usually a microcontroller or embedded microprocessor, is responsible for executing the program stored in the memory and controlling various functions of the device, including data acquisition, logical judgment, and the construction and parsing of communication protocols. The memory includes program memory, data memory, and a dedicated non-volatile storage area (such as a separate data flash chip) for caching historical data. The characteristic of the non-volatile storage area is that data is not lost after power failure, which is key to achieving offline caching. Sensors are used to collect the physical quantities that the terminal device 110 needs to monitor, i.e., operational data, such as temperature sensors, humidity sensors, and pressure sensors. When the terminal device 110 is a temperature control device, it includes at least one temperature sensor for measuring ambient temperature. The communication module is responsible for communication between the terminal device 110 and the outside world. In this embodiment, it is a 4G or 5G wireless communication module, which enables the terminal device 110 to establish a connection with the remote platform 130 through the communication network 120 (e.g., a 4G mobile network of an operator). The real-time clock is a separate timing circuit that maintains time accuracy even when the main MCU is in sleep mode, providing precise timestamps for the acquired operational data.

[0036] The communication network 120 can be any wide area network or local area network that supports data exchange between the terminal device 110 and the platform 130, such as a cellular mobile network (e.g., 4G, 5G), a low-power wide-area network (LPWAN, such as LoRa, NB-IoT), or the Internet. The communication network 120 provides physical and logical channels for data transmission.

[0037] Platform 130 typically refers to a backend service system deployed on a cloud server or private data center, also known as an Internet of Things (IoT) platform. Platform 130 is responsible for communicating with a large number of terminal devices 110, enabling functions such as access management, data reception and parsing, data storage, and data processing and analysis for the terminal devices 110. Within the framework of the data processing system 10 disclosed herein, the terminal devices 110 and platform 130 work collaboratively to ensure that even when the communication network 120 is unstable, data can still be uploaded to platform 130 completely, accurately, and efficiently.

[0038] Specifically, see Figure 2 , Figure 2 This is a schematic diagram illustrating the data interaction between a terminal device 110 and a platform 130 via a communication network 120, as provided in this embodiment of the disclosure. The terminal device 110 executes steps S201 to S203, and the platform 130 executes steps S204 to S207.

[0039] In step S201, when the network connection between the terminal device and the platform is offline, the current running data and current timestamp generated by the terminal device are stored as a historical data record.

[0040] Terminal device 110 collects a set of current operating data at preset time intervals (e.g., every 30 seconds), such as fan speed of 400 RPM and freezer temperature of 5.0℃. Simultaneously, it reads the current time from a real-time clock. To facilitate cross-system processing, this time is typically converted to a Unix timestamp format. For example, 1747045852 is a 4-byte integer corresponding to the time 18:30:52 on May 12, 2025.

[0041] When the network connection between terminal device 110 and platform 130 is offline, the current operating data (fan speed 400, freezer temperature 5.0°C) and the corresponding current time (1747045852) are packaged into a structured data unit and recorded as historical data record.

[0042] See Figure 3 , Figure 3 A schematic diagram of an exemplary queue structure for caching historical data records is shown. A specific area in local memory (such as Flash) is allocated as a data buffer 300. This data buffer 300 can be organized into a First-In, First-Out (FIFO) queue. Each historical data record includes a timestamp and runtime data. Figure 3The historical data records shown, from timestamp 1 to timestamp N, are arranged from oldest to newest. The historical data record consisting of timestamp N and running data N is the most recently generated and is added to the end of the queue. Each historical data record in the queue contains a complete timestamp and corresponding running data. Furthermore, to prevent data buffer overflow, various strategies can be designed. For example: circular queue: when the queue is full, new data overwrites the oldest data. Discard strategy: when the queue is full, new data is directly discarded. Priority strategy: if data has different importance levels, data with lower importance can be discarded first. The specific overflow prevention strategy used is not limited in this disclosure.

[0043] After the caching operation is completed, the process returns to step S201 to continue the next round of data collection and network status assessment.

[0044] In step S202, when the network connection status is restored to online status, a historical data packet is generated based on at least one historical data record.

[0045] The historical data message includes a first starting register address, a register count field, and a data area. The first starting register address is used to indicate a preset address for the historical data message, including a timestamp. The data area includes at least one historical data record. The value of the register count field represents the total number of registers occupied by all historical data records contained in the data area.

[0046] Terminal device 110 determines its network connection status through a response-based acknowledgment mechanism. Each time terminal device 110 sends a data packet to platform 130, it starts a timer. If it does not receive a response packet from platform 130 before the timeout (e.g., within 5 seconds), terminal device 110 determines it is in an "offline state"; otherwise, it is in an "online state".

[0047] Since terminal device 110 is typically resource-constrained, the communication protocol between terminal device 110 and platform 130 is designed to be relatively simple, such as using the Modbus-like protocol provided in this disclosure. This disclosure aims to ensure that the traceability of operational data after a disconnection is achieved without changing the protocol format. Historical data packets refer to data units transmitted between terminal device 110 and platform 130, conforming to the communication protocol between the two, and having a fixed format and structure.

[0048] Table 1 shows the data structures corresponding to the Modbus protocol.

[0049] Table 1. Data Structures Corresponding to Modbus Protocols

[0050]

[0051] Among them, the start byte is a preset field indicating the start of the message, occupying one byte, such as 0xAA; the device address is used to indicate the address of terminal device 110, occupying two bytes; the command is used to indicate the function of the message, occupying one byte, such as 0x50 command code indicating that terminal device 110 uploads data to platform 130; the CRC check code is used to verify whether the message is complete, occupying two bytes; the register count, occupying one byte, indicates the total number of registers; and the running data is the actual data collected.

[0052] In Modbus-like protocols, the start register address is an address number used to specify a specific location in the internal storage area of ​​terminal device 110. Each piece of operational data (such as temperature and speed) to be read or written within terminal device 110 is mapped to a unique register address. In this disclosure, this field is given a dual meaning: firstly, a traditional address pointing function, and secondly, an implicit identifier for the data type. When the start register address is the first start register address, it identifies the data type as a historical data record.

[0053] See Figure 4 , Figure 4 A schematic diagram illustrating the composition of an exemplary historical data packet is shown. The example uses a start byte of 0xAA, a command of 0x50, a CRC checksum of 0x566B, and a device address of 0x01.

[0054] The first starting register address field 401 is set to a special, preset address that corresponds to the "timestamp" parameter, such as... Figure 4 The address shown is 0x0001. This 0x0001 value is used to tell Platform 130 that the data packet is historical data with a timestamp.

[0055] The register count field is 402. Because historical data packets now include a 4-byte timestamp in addition to the original runtime data (in Modbus-like protocols, a 16-bit register occupies 2 bytes, so a 4-byte timestamp requires 2 registers), the number of registers needs to be increased accordingly. For example, if 2 bytes of runtime data originally occupied 2 registers, now with the timestamp, it requires 2 more registers, for a total of 4 registers. Figure 4 The value of this field shown is 0x04.

[0056] The value of register count field 402 can be determined based on the number of at least one historical data record and the preset register length of a single historical data record. For example, if a historical data record requires two registers and the number of at least one historical data record is 4, then the value of register count field 402 is 8.

[0057] Data area 403, each byte represents the value of a register. For example... Figure 4 As shown, 0x6821 represents the value of register 1, 0xCDDC represents the value of register 2, 0x0190 represents the value of register 3, and 0x01F4 represents the value of register 4. Registers 1 and 2 store a timestamp, i.e., 0x6821CDDC, corresponding to the time 2025-05-12 18:30:52. Registers 3 and 4 contain the runtime data corresponding to this timestamp. Figure 4 The fan speed shown is 0x0190, which is 400, and the freezer temperature is 0x01F4, which is 500. Multiplying these values ​​by the preset coefficient 500×0.01=5.

[0058] In step S203, historical data packets are sent to the platform.

[0059] After the historical data message is constructed, the terminal device 110 sends the historical data message to the platform 130 and clears the corresponding historical data record in the data buffer.

[0060] In step S204, a data packet sent by the terminal device is received.

[0061] The data message includes the starting register address, register count field, and data area.

[0062] In step S205, when the starting register address is the first starting register address, the number of historical data records included in the data message is determined according to the value of the register count field and the preset register length of a single historical data record.

[0063] The first start register address is used to indicate that the data packet is a historical data packet with a preset address including a timestamp.

[0064] In step S206, the timestamps and running data of the specified number of historical data records are cyclically parsed from the data area.

[0065] In step S207, runtime data is stored based on timestamps.

[0066] The backend service of platform 130 listens on a designated port, receives data packets from terminal device 110, and performs basic integrity checks (such as CRC checks). Platform 130 parses the data packets according to a predefined protocol format and extracts the starting register address, register count, and data area.

[0067] If the platform 130 determines that the value of the "starting register address" field in the data packet is equal to the preset first starting register address (such as 0x0001), it determines that the data packet is a historical data packet, parses the batch data in a loop according to the number of registers, and stores it into the database based on their respective timestamps.

[0068] Specifically, platform 130 reads the value of the "register count" field (e.g., 40) and combines it with a preset "register length of a single historical data record" (e.g., 4). The quotient of the value of the register count field and the register length of a single historical data record is used to determine the number of historical data records included in the historical data message.

[0069] Platform 130 processes the data area in a loop, executing N times (N equals the number of historical data records). In each loop, it reads the length of a single historical data record, extracting the timestamp and corresponding runtime data. The N parsed historical data records are then batch-inserted into the database, with each record's "Data Time" field using its own embedded timestamp. For example, for timestamp 1747045852, the corresponding record's time in the database will be stored as "2025-05-12 18:30:52".

[0070] In this embodiment, a historical data packet marked with a specific starting register address is constructed for retransmission. This allows the platform 130 to distinguish between real-time and historical data simply by judging the address value, and to accurately recover the historical data using the timestamp carried in the packet. This solution solves the problem of data loss and untraceability caused by network interruption without changing the original packet structure or adding additional signaling fields, ensuring data integrity, and greatly simplifying the implementation logic of the breakpoint resume function.

[0071] In some embodiments, to improve the efficiency of re-reporting after network recovery, the terminal device 110 may not need to send historical data records one by one. For example... Figure 5 The diagram shows a flowchart of an optimized batch reporting method. Terminal device 110 executes steps S501 to S503, and platform 130 executes steps S504 to S507.

[0072] In step S501, when the network connection between the terminal device and the platform is offline, the current running data and current timestamp generated by the terminal device are stored as a historical data record.

[0073] In step S502, when the network connection status is restored to online status, a historical data packet is generated based on multiple historical data records.

[0074] Terminal device 110 can retrieve multiple (e.g., 10) historical data records from the buffer queue at once to construct a longer historical data message. The starting register address of this historical data message remains the first starting register address, but the value of the "register count" field will become much larger. For example, if a single historical record consists of one 4-byte timestamp and two 2-byte runtime data records, and 10 historical data records are reported simultaneously, the corresponding register count field value will be 40. The data area will then contain multiple sets of repeating "timestamp and runtime data" structures.

[0075] When parsing data, Platform 130, after identifying a historical data packet, it iteratively parses all batch-reported data records based on the total data length and the fixed length of each historical data record, and stores them in the database all at once. This method reduces packet header overhead and the number of network interactions, and can clear the local cache more quickly when network conditions are good.

[0076] In step S503, historical data packets are sent to the platform.

[0077] In step S504, a data packet sent by the terminal device is received.

[0078] In step S505, when the starting register address is the first starting register address, the number of historical data records included in the data message is determined according to the value of the register count field and the preset register length of a single historical data record.

[0079] In step S506, the timestamps and running data of the specified number of historical data records are cyclically parsed from the data area.

[0080] In step S507, runtime data is stored based on timestamps.

[0081] For details of steps S501, S503 to S507, please refer to the description of steps S201, S203 to S207 above, which will not be repeated here.

[0082] In some embodiments, this refers to data interaction in an online state. For example... Figure 6 The diagram illustrates the interaction process between a platform 130 and a terminal device 110. The terminal device 110 executes steps S601 to S605, and the platform 130 executes steps S606 to S610.

[0083] In step S601, when the network connection status is online, a real-time data packet is generated.

[0084] The real-time data message includes the second starting register address and the real-time collected running data. The second starting register address is different from the first starting register address.

[0085] When the network connection is online, the goal of the terminal device 110 is to send out the latest collected data as soon as possible. It will construct a "real-time data message", which is "produced and sent immediately" and is sent out as soon as it is generated.

[0086] See Figure 7 , Figure 7 An exemplary composition of a real-time data packet is shown, which follows the same Modbus format as the aforementioned historical data packets. The example used is a start byte of 0xAA, a command of 0x50, a CRC checksum of 0x263C, and a device address of 0x01.

[0087] The second start register address field, 701, is a key field for distinguishing message types. For real-time data messages, this address is set to the address of the first actual operating parameter. According to the communication point table, the address for fan speed is 0x0003, and for freezer temperature is 0x0004. Therefore, if these two parameters are to be sent, the start address is set to 0x0003.

[0088] The communication point table is a pre-stored guide table that includes the parameter type corresponding to the register start address, such as 0x0001 for timestamp, 0x0003 for fan speed, 0x0004 for freezer temperature, as well as the scaling factor, length, and unit of each parameter.

[0089] Register count field 702: Taking the reported fan speed and freezer temperature as an example, there are two corresponding registers, so the value of this field is 0x02.

[0090] Data area 703: Stores the values ​​of various operating parameters sequentially, excluding timestamps. For example, fan speed 400 (0x0190 in hexadecimal), freezer temperature 500 (because the scaling factor is 0.01, the actual value 5.0 is represented as 500 in the protocol, which is 0x01F4 in hexadecimal).

[0091] In step S602, the real-time data message is sent to the platform.

[0092] After the construction is completed, the terminal device 110 sends the real-time data message to the platform 130.

[0093] In step S603, when the network connection between the terminal device and the platform is offline, the current running data and current timestamp generated by the terminal device are stored as a historical data record.

[0094] In step S604, when the network connection status is restored to online status, a historical data packet is generated based on at least one historical data record.

[0095] In step S605, historical data packets are sent to the platform.

[0096] In step S606, a data packet sent by the terminal device is received.

[0097] In step S607, when the starting register address is the first starting register address, the number of historical data records included in the data message is determined according to the value of the register count field and the preset register length of a single historical data record.

[0098] In step S608, the timestamps and running data of the specified number of historical data records are cyclically parsed from the data area.

[0099] In step S609, runtime data is stored based on timestamps.

[0100] In step S610, if the starting register address is the second starting register address, the running data in the data area is stored based on the platform's current time.

[0101] When the starting register address is not the first starting register address (e.g., 0x0001) (e.g., 0x0003), the platform 130 treats it as a real-time data message, directly parses the running data in the data area, and uses the current system time of the platform 130 as the data timestamp to store it in the database.

[0102] Through this simple, single-field-value-based judgment logic, Platform 130 can seamlessly process data from two sources, ultimately forming a complete, uninterrupted, and time-accurate data timeline at the database level.

[0103] It should be noted that steps S603 to S609 can be referred to in the description of steps S201 to S207 above, and will not be repeated here.

[0104] In this embodiment, a unified data message format is defined, cleverly reusing the "start register address" field in the message as an implicit data type identifier: when the terminal device 110 is offline, it caches timestamped runtime data, and when it re-uploads the historical data cached during the offline period after reconnecting, this address is set to a preset value pointing to the timestamp; while when transmitting real-time data, it is set to a regular data parameter address. The platform 130 can accurately distinguish and process the two types of data by judging the difference in this address value. This solution does not require adding or modifying protocol fields, achieves reliable traceability of historical data with low implementation complexity while maintaining the simplicity and compatibility of the protocol framework, and significantly reduces system development costs.

[0105] There is a situation where, when the network status returns to online, if there are many historical data records, it may not be possible to complete the transmission in a short time, but real-time data needs to be transmitted. In this case, to improve transmission efficiency, in some embodiments, such as... Figure 8 The diagram illustrates the interaction process between a platform 130 and a terminal device 110. The terminal device 110 executes steps S801 to S807, and the platform 130 executes steps S808 to S813.

[0106] In step S801, when the network connection status is online, a real-time data packet is generated.

[0107] In step S802, the real-time data message is sent to the platform.

[0108] In step S803, when the network connection between the terminal device and the platform is offline, the current running data and current timestamp generated by the terminal device are stored as a historical data record.

[0109] In step S804, when the network connection status is restored to online status, a historical data packet is generated based on at least one historical data record.

[0110] In step S805, historical data packets are sent to the platform.

[0111] In step S806, if at least one historical data record is not sent to the platform and real-time data is generated, a mixed data message is generated based on at least one historical data record and the real-time collected operation data.

[0112] The mixed data message includes a first starting register address, a register count field, and a data area. The data area includes at least one historical data record, a second starting register address, and real-time collected runtime data.

[0113] In step S807, the mixed data message is sent to the platform.

[0114] In step S808, a data packet sent by the terminal device is received.

[0115] In step S809, when the starting register address is the first starting register address, the number of historical data records included in the data message is determined according to the value of the register count field and the preset register length of a single historical data record.

[0116] In step S810, the timestamps and running data of the specified number of historical data records are cyclically parsed from the data area.

[0117] In step S811, runtime data is stored based on timestamps.

[0118] In step S812, after parsing the number of historical data records from the data area, if there is remaining data in the data area, the remaining data is stored based on the current time of the platform.

[0119] The mixed data message includes at least one historical data record that has not yet been uploaded to platform 130 and one currently generated real-time data record. Both types of data are reported to platform 130 in a single message. For example... Figure 9 As shown, the first starting register address field 901 is 0x0001, the register count field 902 is 0x04, and the data area 903 contains: 0x6821, 0xCDDC, 0x0190, 0x01F4, 0x0003, 0x02, 0x0180, 0x01F2. A historical data record requires a register length of 4, and the number of historical data records is 4 / 4, resulting in 1, indicating that there is one historical data record. Figure 9 Data area 904, a portion of data area 903, contains historical data records.

[0120] During parsing, after parsing a historical data record, Platform 130 determines that there is still 905 data records remaining in the data area. This remaining data 905 is identified as real-time data. Based on the data structure of register address, register count, and running data, the corresponding register address is determined to be 0x0003, the register count field to be 0x02, and the running data to be 0x0180 and 0x01F2. The current time of Platform 130 is used as the timestamp for data entry. This method allows for the transmission of both real-time and historical data in a single transmission, accommodating both data types and improving transmission efficiency.

[0121] In step S813, if the starting register address is the second starting register address, the running data in the data area is stored based on the platform's current time.

[0124] The processing unit 1002 is used to generate a historical data packet based on at least one historical data record when the network connection status is restored to online status. The historical data packet includes a first starting register address, a register count field, and a data area. The first starting register address is used to indicate a preset address for the historical data packet including a timestamp. The data area includes at least one historical data record.

The mixed data message includes a first starting register address, a register count field, and a data area, the data area including: at least one historical data record and real-time collected runtime data.
