Obviously, the drawings in the following description are only some embodiments of the present application. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

Detailed Embodiments

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0022] With the development of motor intelligent control technology, the data acquisition module, as the "eyes" and "ears" of the vehicle control core, can perceive and monitor various key parameters in real time. These parameters are crucial for the efficient operation, optimized control, and safety guarantee of the motor. Among them, the data acquisition module mainly monitors the operating state of the target motor through various sensors. The data collected by the data acquisition module includes but is not limited to key parameters such as current, voltage, temperature, and speed. In different usage scenarios, real-time monitoring of multiple levels of targets may also be involved, resulting in a large amount of monitoring data, causing problems such as unreasonable allocation of data storage resources and chaotic data writing during concurrent operation control of the same target data.

[0023] Next, from the perspective of the dynamic storage control device for the motor control system, the dynamic storage control method for the motor control system provided by the embodiments of the present application will be described in combination with the process of controlling a new energy vehicle integrated with multiple motors.

[0024] As Figure 1 shown, it is a flowchart of the dynamic storage control method for the motor control system provided by the embodiments of the present application. The dynamic storage control method for the motor control system provided by the embodiments of the present application includes the following steps.

[0025] Step S11: Determine the priorities of multiple received write requests according to a preset data priority classification method.

[0026] It should be understood that the write requests include but are not limited to data sources, data contents, timestamps, and metadata, etc. In the vehicle control system, key data related to motor control (such as control commands, key fault information, and high-risk data, etc.) has extremely high requirements for the real-time performance and reliability of the system. These data are directly related to the safety and performance of the vehicle. If processed untimely or errors occur, serious consequences may occur, such as vehicle out of control, accidents, etc. In contrast, non-critical data such as debugging data has lower requirements for the real-time performance and reliability of the system. These data are mainly used for system debugging, performance analysis, etc. Even if there is a slight delay or loss in processing, it will not directly affect the basic functions and safety of the system.

[0027] Therefore, by classifying the write requests by priority, resources can be reasonably allocated and reasonable control management methods can be adopted for different data, so as to ensure that the system can respond and store key data in a timely manner, and ensure the stability and safety of the system. In this embodiment, according to the different importance of the data content in the write request to the system operation and functions, critical data is defined as high-priority data, and non-critical data is defined as low-priority data, thereby establishing a mapping table between the data content and the priority.

[0028] When receiving multiple write requests, the data content in the write requests is read to traverse a preset mapping table between data content and priorities according to the data content, so as to perform priority matching on the write requests.

[0029] Step S12: Calculate the first storage space of each write request according to a preset dynamic storage calculation formula and the priority.

[0030] After receiving a write request, the available space size in the memory for data storage is obtained by reading the memory, so as to perform space dynamic allocation calculation according to the storage space required by the write request, the priority, and the available space of the memory, thereby obtaining the first storage space representing the storage requirements of each write request to achieve reasonable allocation of storage resources.

[0031] The first storage space is calculated by the following formula: ; where, the is the first storage space of the write request received at time t. The is the storage requirement in the write request, which is used to represent the size of the data in the write request. The is the priority. The is the first coefficient corresponding to the priority, which is used to adjust the storage space requirement according to the priority. The is the available space at time t. The is the second coefficient corresponding to the available space at time t, which is used to adjust the storage space allocation strategy according to the available space size.

[0032] According to different priorities, in this embodiment, a mapping table between preset priorities and first coefficients is adopted to map each priority to a corresponding first coefficient. The first coefficient is a positive value, and the higher the priority, the larger the corresponding first coefficient, so as to increase the storage space requirement for high-priority data. After obtaining the priority corresponding to the write request, the first coefficient corresponding to the write request is obtained according to the priority of the write request and the preset mapping table between priorities and first coefficients. Similarly, in this embodiment, according to the available space obtained by reading the memory and the preset mapping table between available space and second coefficients, the second coefficient of the write request is determined, so as to flexibly adjust the storage space size of each write request according to the remaining space in the memory.

[0033] Exemplarily, at a certain moment t , the remaining available space in the memory = 1000 MB. At this time, the system receives a write request with a storage requirement Di = 200 MB and a priority of 3, where the priority range is from 1 to 5 and 5 is the highest priority. According to the priority mapping table, the first coefficient PF(Pi) corresponding to priority 3 = 0.2. According to the available space mapping table, the second coefficient AF( S avail(t)) = 1.0.

[0034] According to Calculating to obtain Δ S ( t ) = 200 × (1 + 0.2) × 1 = 200 × 1.2 × 1 = 240 MB. Therefore, the first storage space required for this write request at the moment is 240 MB.

[0035] In an alternative embodiment, to avoid the sum of the first storage spaces calculated based on the same available space being greater than the available space when different write requests are received at the same moment, resulting in the memory being unable to meet the storage requirements of all write requests and causing critical data loss, the method further includes: Calculating the pre-allocated storage space through the following formula: ; wherein, the is the storage space that the memory needs to allocate at time t, the is the pre-allocated storage space that the memory needs at time t + 1, and the is the sum of the respective first storage spaces calculated at time t.

[0036] And comparing the pre-allocated storage space with a preset second threshold. When the pre-allocated storage space reaches the preset second threshold, alarm and data storage are performed according to a preset emergency storage method. Among them, the second threshold is set according to relevant factors such as the total capacity of the memory and the expected number of write requests.

[0037] Exemplarily, during the vehicle exit collision experiment detection process, at time t, the storage space already allocated by the memory is Salloc(t) = 100 MB, the available space is 100 MB, and the preset second threshold is 200 MB. At the same time, three write requests are received, namely request A, request B, and request C. The storage requirement of request A is D A = 20 MB, and the first coefficient corresponding to the priority P A is PF(P A ) = 0.2; the storage requirement of request B is D B = 30 MB, and the first coefficient corresponding to the priority P B is PF(PB ) = 0.1; The storage requirement of Request C is D C = 50 MB, priority P C The corresponding first coefficient is PF(P C ) = 0. And according to the available space, the second coefficients are all determined to be 1.

[0038] Through Calculate to obtain ΔS A (t) = 24MB, ΔS B (t) = 33MB, ΔS C (t) = 50MB, according to Calculate to obtain = 207MB. Since is greater than 200MB (i.e., the pre-allocated storage space reaches the preset second threshold), the system uploads the received Request A, Request B, and Request C to the cloud storage network disk for backup through the connected vehicle system according to the preset emergency storage method, and responds to the write requests of Request A and Request B with higher priorities. At the same time, generate fault information according to the preset alarm method and send it to the corresponding management personnel, so as to remind the management personnel to take corresponding measures in time.

[0039] By comparing the pre-allocated storage space with the preset second threshold, when the storage space is insufficient that may occur in high-concurrency write requests, the preset emergency storage method is adopted for alarm and data storage backup, so that critical data is preferentially stored, thereby reducing the risk of data loss. At the same time, by notifying the administrator through the alarm, the administrator can fully understand the status of the storage system and take intervention measures when necessary, improving the manageability and monitorability of the system.

[0040] Step S13: Determine the write method of the write request according to the priority, and determine the data to be written according to the write method and the write request.

[0041] It should be understood that the motor control system needs to control the operation of the motor in real time and accurately to ensure the safety, performance and efficiency of the vehicle. Therefore, key data directly related to the motor state, control instructions, etc. (such as current, voltage, speed, position, etc.) needs to be updated frequently to reflect the latest state of the motor and make adjustments accordingly. At the same time, in the motor control system of electric vehicles, in order to reduce the detection error of key data, multiple sensors are usually used to cooperate to monitor the working state of the same motor. The data collected by each of these sensors needs to be updated and fused frequently to generate more reliable and comprehensive motor state information. Therefore, there is a phenomenon of high-concurrency writing operations for write requests of key data. However, high-concurrency writing operations will significantly increase the load of the storage system, may lead to a decline in storage performance, and then affect the overall response time and real-time performance of the system. At the same time, high-concurrency writing operations may trigger the protection mechanism of the storage system (such as write protection, lock mechanism, etc.), resulting in the system entering an unstable state, thus causing the loss of key data and even triggering a system crash.

[0042] After determining the priority corresponding to the write request, the system adds a priority label at a specific position (such as the head of the write request data packet) of each write request according to the determination result of the priority of the write request and the preset priority label adding method. Exemplarily, the preset number 1 is a high-priority label, and the number 0 is a low-priority label. After receiving a new write request and determining that the priority of the write request is high priority, the system adds the number 1 as the priority label of the write request at the head of the data content of the write request.

[0043] It should be understood that the priority is used to represent the criticality and update frequency of the data content in the write request. In the embodiments of the present application, a real-time writing mechanism (i.e., the first writing method) is adopted for non-critical data, and a cache writing mechanism (i.e., the first writing method) is set for the characteristic of frequent update of critical data.

[0044] By parsing the priority label, the system divides the multiple received write requests into real-time update requests (i.e., non-critical data write requests) and frequent update requests (i.e., critical data write requests), so as to determine the write method corresponding to each write request by querying the mapping table between the preset write request classification result and the write method.

[0045] When the priority is the low priority, the write request is a preset real-time update request, and the write method adopts a preset first write method. The system parses the write request according to the first write method to obtain the target information in the write request, so as to record the target information in a preset working log. The target information includes, but is not limited to, information such as data content, timestamp, and request source. At the same time, format and encode and encrypt the data content to generate the data to be written that meets the requirements of the storage system data format.

[0046] When the priority is the high priority, the write request is a preset frequent update request, and the write method adopts a preset second write method. The system stores the write request in a cache area, so as to reduce the number of writes to the EEPROM. By parsing the data content (i.e., the operation object) in the write request, multiple frequent update requests are classified according to the operation object, so that multiple frequent update requests corresponding to the same operation object are grouped into a set to form a data version set.

[0047] In each data version set, the frequent update requests are sorted according to the timestamp in the write request in the order of receiving time. At the same time, monitor the number of frequent update requests in each data version set.

[0048] When the number of write requests temporarily stored in a certain data version set reaches a preset first threshold, stop storing frequent update requests in the data version set, and according to the sorting order of the timestamps, obtain the write request with the latest receiving time (i.e., the latest write request) in the data version set, so as to determine the data in the write request as the data to be written.

[0049] Exemplarily, in a vehicle motor detection experiment, the EEPROM system receives multiple high-priority write requests transmitted by multiple sensors. The system classifies multiple write requests into 4 different data version sets according to the different operation objects in the write requests, and sorts the write requests in the data version sets according to the timestamps in each write request in the order of receiving time. When the number of write requests in the data version set corresponding to the rotational speed (hereinafter collectively referred to as the rotational speed data version set) reaches 10, stop inputting newly received rotational speed write requests into the current rotational speed data version set, and at the same time generate a new cycle of rotational speed data version set for continuing to store newly received rotational speed write requests. At the same time, select the latest rotational speed write request from the current rotational speed data version set according to the sorting of the write requests, and determine the rotational speed write request as the data to be written.

[0050] In an alternative embodiment, to implement the storage update of the data version set in the cache area, the method further includes: obtaining multiple data version sets of the same operation object according to the operation object, sorting the data version sets according to the chronological order of the generation time of the data version sets, and simultaneously monitoring the residence time of the data version sets in the cache area in real time through a preset timer. When the duration counted by the timer is equal to a preset duration threshold, the earliest generated data version set is deleted according to the sorting order of the data version sets, so as to release the cache space and ensure that the newer data version sets are retained.

[0051] In an alternative embodiment, to ensure the accuracy of the data to be written, the write requests in the data version set are verified before determining the data to be written, so as to avoid data being tampered with or damaged. Calculate the hash value of each frequently updated request classified according to the operation object according to a strong hash algorithm (such as SHA-256 or a later version of the SHA algorithm), and append the calculated hash value to the front or back of the original frequently updated request to form a new data packet, so as to write the data packet with the hash value into the data version set. When the latest write request is selected, recalculate the hash value in the data packet corresponding to the latest write request, and compare the recalculated hash value with the hash value in the data packet. When the two match, the data has not been tampered with or damaged, and the latest write request is determined as the data to be written; if they do not match, the data may have problems, and a preset error handling measure is taken to reselect the latest write request (for example, obtaining the second-to-last frequently updated request in the sorting as the latest write request).

[0052] Step S14: Determine the storage location of the write request according to the priority.

[0053] It should be understood that critical data will be allocated to the more stable and frequently written first storage area. The first storage area has a higher write rate and lower latency, and has strong durability, suitable for processing data with high-frequency updates. Non-critical data can be stored in the second storage area that is not frequently updated. The second storage area has a lower write frequency and relatively poor storage durability, but is sufficient to meet the storage requirements of data with a low update frequency.

[0054] According to the priority, it can be determined whether the data (i.e., the operation object) to be modified by the write request is critical data, so as to determine the storage location of the data content in the write request. When the write request is a high-priority write request, the data in the write request is critical data, and the write request is confirmed to be stored in the first storage area; when the write request is a low-priority write request, the data in the write request is non-critical data, and the write request is confirmed to be stored in the second storage area.

[0055] Allocating storage locations according to the priority of write requests enables the system to flexibly adapt to different data storage requirements.

[0056] Step S15: Store the data to be written according to the storage location and the first storage space.

[0057] Store the data to be written into the previously allocated storage location according to the calculated size of the first storage space. After the storage operation is completed, update the status information of the storage area. The status information includes, but is not limited to, used space and available space, etc. At the same time, the system will also record the log information of the storage operation for subsequent data management and troubleshooting.

[0058] This application is applied to the field of storage management technology. It determines the priorities of multiple received write requests through a preset data priority classification method, calculates the first storage space for each write request according to a preset dynamic storage calculation formula and the priority, determines the write method for each write request based on the priority to extract the data to be written in each write request, and determines the storage location of the write request based on the priority, so as to store the data to be written according to the storage location and the first storage space. This application classifies the priorities of multiple received write requests, calculates the first storage space for each write request according to the priority, realizes the dynamic allocation of storage space, ensures the reasonable utilization of storage space and avoids the waste of storage resources. At the same time, determines the write method of the write request according to the priority, classifies multiple write requests and generates a data version set, and sorts according to the time stamp to ensure the version control and update order of the data, so as to avoid data chaos and conflicts caused by high-concurrency write operations.
