Description

Technical Field

[0001] The present invention mainly relates to the technical field of communication data processing, and particularly relates to a data processing method, apparatus and electronic device. Background Art

[0002] Communication data processing involves collecting, transmitting, storing, analyzing and applying the data generated in a communication system. In the photovoltaic field, the electronic control system of a tracking bracket is mainly divided into two parts: a control end (TCU) and a communication end (NCU). Among them, as an important node for data convergence and information upload in the entire bracket electronic control system, there are multiple communication nodes for both the upstream and downstream of the data in the communication end, which belongs to the communication bottleneck of the entire intelligent bracket system. Therefore, the immediacy and integrity of data processing by the NCU determine the stability and efficiency of data update and synchronization of the entire system.

[0003] Currently, the data processing method of NCU devices mainly receives and sends through an ordinary foreground-background mechanism. When a new packet of data arrives, the processor stores the data in the background interrupt, and then calls out the foreground task for parsing and data reply. When the total communication frequency is higher than a certain level or multiple data are concurrent, since the TCP protocol cannot distinguish the partition relationship between data, a packet sticking phenomenon may occur, that is, two data packets are stuck together in sequence. For an ordinary protocol parsing system, usually only the frontmost frame of data will be processed, and the subsequent data will be discarded entirely, which will result in packet loss.

[0020] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Without further statement, the above words have no special meaning, so it cannot be understood as a limitation on the protection scope of the present application. In addition, although the terms used in the present application are selected from well-known and commonly used terms, some of the terms mentioned in the specification of the present application may be selected by the applicant according to his or her judgment, and their detailed meanings are described in the relevant parts of this description. In addition, it is required to understand the present application not only through the actual terms used, but also through the meaning implied by each term.

[0021] Flowcharts are used in the present application to illustrate the operations performed according to the embodiments of the present application. It should be understood that the previous or following operations are not necessarily executed precisely in sequence. On the contrary, they can be executed in reverse order or simultaneously. At the same time, other operations can be added to these processes, or one or more operations can be removed from these processes.

[0022] Refer to Figure 1 as shown, Figure 1 is a schematic flowchart of a data processing method according to an embodiment of the present invention. The first processing unit performs data clipping and data unpacking on the data to be processed, including: S110, the data clipping includes: according to the length value indicating a single data packet, clipping several bytes of data with the corresponding length value as a data packet; S120, the data unpacking includes: determining the length of a single-frame data; unpacking the data packet according to the length of the single-frame data to obtain multiple single-frame data; wherein, the length of the single-frame data is determined by one or more of the following methods, including: according to the fixed value of the frame length in the data protocol, the description of the data frame length recorded in the data protocol, and the characteristic value in the data protocol.

[0023] When the total communication frequency is higher than a certain level or multiple data are concurrent, due to the TCP protocol's inability to distinguish the segmentation relationship between data, a packet adhesion phenomenon may occur, that is, two data packets are adhesively connected in sequence front and back. For ordinary protocol parsing systems, usually only the frontmost frame of data is processed, and the subsequent data is all discarded, which will lead to packet loss.

[0024] In this embodiment, when processing network traffic data, in order to ensure that the packet length meets some requirements, the data packets can be trimmed. In some communication protocols, the length information of the data packet is stored in a specific field of the packet header. A decoder can be used to parse these length fields and trim the data packets according to the specified length. Trimming is to extract the next complete received data packet to be processed. Then, the data is unpacked. Since there may be a situation where two packets are adhesively connected in a complete data packet trimmed, unpacking is needed to separate them. Exemplarily, according to the different protocols loaded, the data packets can be separated in one or more of the following ways: 1. In some protocols, the frame length is a fixed value, and a classification and screening can be performed according to the length value; 2. The content describes its own length. In some protocols, the length description of its own data frame is stored at a fixed position, and a classification and screening can be performed on this; 3. In some protocols, the fixed position is the protocol identification code, function code, etc., and a classification and screening can be performed according to this. In summary, through one round or multiple rounds of screening in the above ways, several lengths of data are judged and trimmed and defined as a data frame conforming to the corresponding protocol.

[0025] The method of this embodiment performs integrity analysis on a data packet, and through one round or multiple rounds of screening by various types of different protocols loaded in the system, it is judged whether there is packet adhesion, and the data frames of multiple different protocols are independently segmented and data parsing is performed in sequence.

[0026] In an example, trimming a number of bytes of data corresponding to the length value as a data packet according to the length value indicating a single data packet includes: defining a frame buffer pointer and a frame length pointer. Initially, the frame buffer pointer points to the starting position of the data storage area, and the frame length pointer points to the starting position in the data length array; according to the length value saved at the position pointed to by the frame length pointer, using the current position pointed to by the frame buffer pointer as the starting point, trimming a number of subsequent bytes of data with the length value as a data packet.

[0027] Frame buffer pointers are often used to point to a certain position in the frame buffer (Frame Buffer). Through the frame buffer pointer, pixel data in the frame buffer can be quickly accessed. Frame length pointers are often used to point to a field or memory location storing frame length information. Frame length information is used to identify the size of a data frame and is usually used in network communication to parse and process data frames. The main function of the frame length pointer is that through the frame length pointer, the length information of the data frame can be quickly obtained, so as to correctly parse and process the data frame. For example, in an Ethernet frame, the frame length field is used to identify the length of the data field. Frame buffer pointers are mainly used to manage the receive and transmit buffers in a network interface card (NIC) to ensure that data can be correctly stored and transmitted. By reasonably using frame buffer pointers and frame length pointers, the efficiency and reliability of network communication can be improved, and at the same time, the data processing logic can be simplified.

[0028] Exemplarily, first define a frame buffer pointer and a frame length pointer. In the initial state, the former points to the starting position of the circular buffer, and the latter points to the starting position in the aforementioned data length array. According to the length value saved at the position pointed to by the frame length pointer, the relevant function will use the position pointed to by the frame buffer pointer as the starting point and cut out several bytes of data with subsequent length values as the data packet to be processed currently.

[0029] In one example, refer to Figure 2 As shown, the data processing method further includes: S210, parsing the frame data by the first processing unit; in response to being unable to perform the data parsing of the current frame data, indicating that there is a packet adhesion in the current frame data.

[0030] In this embodiment, if there is no packet adhesion, the data parsing task can be directly performed on the current data; if there is packet adhesion, the data parsing of the current frame data cannot be performed. Therefore, the first frame in the current packet can be disassembled according to the packet adhesion separation algorithm and input into the data parsing task for processing. The above processes of disassembling and parsing are executed until the data in the packet is processed completely.

[0031] In one example, the data to be processed is extracted from the second processing unit, and the parsed data is stored back in the second processing unit. Refer to Figure 3 As shown, in this embodiment, the second processing unit stores data, transmits the data to be processed to the first processing unit, receives external communication data and / or sends communication data to an external unit. Based on this, the general process of processing data by the first processing unit includes: 310, the data to be processed is extracted from the second processing unit; S110, performing data clipping, including: according to the length value indicating a single data packet, clipping several bytes of data with the corresponding length value as a data packet; S120, performing data unpacking, including: determining the length of a single-frame data; unpacking the data packet according to the length of the single-frame data to obtain multiple single-frame data; S320, and the parsed data is stored back in the second processing unit.

[0032] The complete data processing cycle occupies too much of the MCU processor. For data reception, parsing, and sending, the MCU needs to participate in the operations, resulting in low efficiency. Moreover, when the total communication frequency is higher than the processor's processing frequency, it will cause congestion in the communication link, leading to packet loss or slow response. Even, due to the excessive occupation of the MCU for communication task processing, it will affect the normal operation of other functions in the device. Especially when the total communication frequency is higher than a certain level or multiple data are concurrent, data congestion is bound to occur. The ordinary foreground / background processing mechanism belongs to a blocking process that only instantaneously processes the current data packet and cannot receive or process new data during operation, resulting in packet loss.

[0033] In this embodiment, the first processing unit processes data, while the second processing unit stores data and data transmission. Exemplarily, data is first received and sent through DMA (Direct Memory Access), thus saving the occupation of the MCU. That is, only the parsing process truly requires the MCU to participate, shortening the data processing cycle, improving the operating efficiency of the NCU itself, and the communication timeliness and synchronization of the overall communication system. Using DMA to send and receive data makes this process no longer occupy the MCU, realizing the dual-thread operation of the system and greatly improving the processing efficiency. Especially for high-frequency and concurrent data, it has extremely high processing flexibility, ensuring the integrity of data reception and reducing the packet loss rate.

[0034] In one example, the second processing unit stores data in a circular buffer manner, and the second processing unit receives external communication data and / or sends communication data to external units.

[0035] A circular buffer is a buffer with a fixed size. Its characteristic is that the head and tail are connected to form a circular structure. When data is written to the end of the buffer, it will automatically wrap around to the beginning of the buffer to continue writing. The size of the buffer is pre-allocated and cannot be dynamically expanded. When the buffer is full, new data will overwrite the oldest data (configurable to block or discard). The writing and reading of data are managed by read and write pointers. By adding a circular buffer for data sending and receiving and queuing and processing according to the FIFO principle, it ensures the complete reception and proper processing of all data in high-frequency and concurrent situations. Generally speaking, normal functions require the CPU to process and execute, but DMA can perform the sending / receiving function by itself, equivalent to dual-line operation.

[0036] The method of this embodiment adds a circular buffer for data sending and receiving, which is queued and processed according to the FIFO principle to ensure the complete reception and reliable processing of all data in high-frequency and concurrent situations. During operation, the DMA will transfer all received data to the circular buffer in sequence. If the packet data has reached the tail of the circular buffer, the remaining data content will be anchored to the head of the circular buffer for continued storage, thus ensuring the integrity of the data packet. The DMA channel in the MCU can directly transfer the data of the specified interface to the inside of the CPU without the participation of the CPU, and the transmission efficiency is much higher than the conventional foreground and background methods.

[0037] In one example, the method of this embodiment further includes: the second processing unit defines the task stack number, which corresponds to the number of unparsed data packets in the storage area, and the task stack number indicates whether to start the data processing process of the first processing unit. In one implementation, in the second processing unit, the task stack number is initialized to zero; for each received external communication data packet, the task stack number is incremented by 1, and for each data packet transmitted to the first processing unit, the task stack number is decremented by 1; in response to the task stack number not being zero, the data processing process of the first processing unit is started.

[0038] Each time a new packet of data is received, the length of the packet will be stored in an array to distinguish each packet of data in the buffer, and the task stack number will be incremented by one. When the processing system detects that the task stack is not 0, it means that there are currently unparsed data packets. As described above, according to the length value saved at the position pointed to by the frame length pointer, the relevant function will use the frame buffer pointer as the starting point and cut out several bytes of data with the subsequent length value as the data packet to be processed currently. At the same time, the frame buffer pointer moves backward by the position of the length value, the frame length pointer moves backward by one position, and the task stack number is decremented by 1. If the task stack number is still not 0, the above loop will continue, and the data packets will be processed according to the first-in-first-out processing principle.

[0039] Exemplarily, if two packets of data are received within a short period of time, FF 00 01 02 03, FF 01 02 03 04 FF 02 03 04 05, the former is normal data and the latter has packet sticking. At this time, both packets of data will be sequentially stored in the circular buffer for analysis. The data in the circular buffer is {FF 00 01 02 03 FF 01 02 03 04 FF 02 03 04 05}, both the frame buffer pointer and the frame length pointer are 0, and at the same time, the received data lengths will be sequentially stored in the frame length array as {05, 10}, and the task stack count is 2. When the CPU is idle and it detects that the task stack count is not equal to 0, it starts to clip data from the circular buffer. First, since the frame length pointer is 0, it obtains the frame length 5 at the 0 position of the frame length array, and updates the frame length pointer to 0 + 1. Since the frame buffer pointer is 0, it takes 5 bytes of data from the 0 position of the circular buffer, and updates the frame buffer pointer to 0 + 5, which is FF 00 01 02 03. Assume that only protocol A is loaded at this time, and the packet frame header is fixed as FF, so the data inside the packet does not need to be separated, and the data is sent to the next data parsing task, and then the reply data is sent to the DMA for automatic transmission, and the task stack count is -1. It detects again that the task stack count is not 0 and repeats the above steps. At this time, the frame length pointer is 1, so it obtains the frame length 10 at the 1 position of the frame length array, and the frame buffer pointer is 5, that is, it starts to clip 10 bytes of data from the 5 position of the circular buffer, which is FF 01 02 03 04 FF 02 03 04 05. If the frame header is correct, it passes through the in-packet data separation task and proceeds to the next data parsing. However, it is found that the parsing cannot be executed (because the two packets of data are stuck together and the data format is incorrect), so the data of this packet is re-executed for the in-packet data separation task. By screening the frame header, it is found that there is another frame header in the data packet. The data packet is disassembled into two packets, FF 01 02 03 04 and FF 02 03 04 05, and then the data parsing task is executed.

[0040] In the data processing method of this embodiment, the first processing unit performs data clipping and data unpacking on the data to be processed. Among them, data clipping includes: according to the length value indicating a single data packet, clipping several bytes of data with the corresponding length value as a data packet; data unpacking includes: determining the length of a single-frame data, and unpacking the data packet according to the length of the single-frame data to obtain multiple single-frame data; among them, the length of the single-frame data is determined by one or more of the following methods, according to the fixed value of the frame length in the data protocol, the description of the data frame length recorded in the data protocol, and the characteristic value in the data protocol. Furthermore, the requirements for the data source can be reduced, the configuration of the communication system can be made more flexible, the situation of data packet sticking and packet loss can be reduced, and the effective processing of data can be achieved. In addition, through the second processing unit, data is separately stored or data transmission and data communication are performed, realizing the dual-thread operation of the processing system and greatly improving the processing efficiency.
