The following describes an example of the smart home information processing method provided by the present invention, with the control device 100 shown in fig. 1 as an exemplary execution subject.
Referring to fig. 2, fig. 2 is a flowchart of a new energy vehicle fault data processing method according to an embodiment of the present invention, where the new energy vehicle fault data processing method includes the following steps:
step S201, obtaining automobile state data to be processed sent by a front-end detection node;
in the embodiment of the present invention, the front end detection node may be various sensors provided on the new energy vehicle, such as a liquid level sensor for detecting a liquid level of the antifreeze, a current sensor for detecting whether a lamp of the vehicle is faulty, and the like. The front-end detection node may send information such as the aforementioned level of the antifreeze, whether the vehicle lamp is faulty, or not, to the control device as the vehicle state data to be processed.
The front-end detection node can continuously acquire various state information of the automobile and package all the state information to be used as automobile state data to be processed for storage; and the control equipment can acquire the to-be-processed automobile state data stored by the front-end detection node from the front-end detection node at preset time intervals.
Step S202, analyzing the automobile state data to be processed, and counting all intermittent fault data from a first data block of the automobile state data to be processed to obtain an intermittent fault set; the first data block is a preset area for storing fault data with the fault duration time less than a first duration;
step S203, judging whether the accumulated total duration of all intermittent fault data in the intermittent fault set meets a first preset threshold value;
step S204, when the accumulated total duration of all intermittent fault data in the intermittent fault set does not meet the first preset threshold, reading continuous fault data from a second data block of the automobile state data to be processed to obtain a continuous fault set; the second data block is a preset area for storing fault data with the fault duration time being greater than or equal to the first duration; the second data block and the first data block are data blocks with different automobile state data to be processed;
step S205, copying all intermittent fault data in the intermittent fault set to a comprehensive fault set;
step S206, all continuous fault data with the fault duration time smaller than a second time length in the continuous fault set are added to the comprehensive fault set; wherein the second duration is greater than the first duration;
step S207, sending out first fault reminding indication information according to respective fault duration of all fault data in the comprehensive fault set.
In the embodiment of the invention, all fault data can be divided into intermittent fault data and continuous fault data according to the duration of each fault data; for example, with a preset first duration as a boundary, determining fault data with a duration less than the first duration as intermittent fault data, and determining fault data with a duration greater than or equal to the first duration as persistent fault data, so that when the control device analyzes the vehicle state data to be processed, the intermittent fault set and the persistent fault set can be respectively counted according to the first data block and the second data block in the vehicle state data to be processed.
When the accumulated total duration of all intermittent fault data in the intermittent fault set meets the first preset threshold, the control equipment can send out reminding information to remind a user of paying attention to the state of the automobile in time, so that the detection control capability of automobile faults is improved, and the safety and the reliability of the automobile are enhanced.
On the contrary, when the accumulated total duration of all intermittent fault data in the intermittent fault set does not satisfy the first preset threshold, all intermittent fault data in the intermittent fault core network may be copied to the comprehensive fault set, and all continuous fault data with a fault duration less than the second duration are screened from the continuous fault set and added to the comprehensive fault set.
Therefore, the control equipment can send out first fault reminding indication information according to the respective fault duration of all fault data in the comprehensive fault set, so that a user can pay attention to certain faults which do not influence the current driving of the automobile and can maintain the faults in time, and the influence of certain conventional fault problems on the driving of the automobile due to the fact that the faults are not processed in time is avoided.
Wherein, in order to accurately identify the respective intermittent fault data, in some embodiments, step S202 may include the following sub-steps:
step S2021, reading the metadata information of the first data block to obtain a first start identifier and a first end identifier in the first data block; the first start identifier is used for indicating a start address for storing intermittent fault data, the first termination identifier is used for indicating a termination address for storing intermittent fault data, and a start storage address of each intermittent fault data is further stored in metadata information of the first data block;
step S2022, creating a first data directing pointer; wherein the first data direction pointer is used for pointing to a starting storage address of intermittent fault data in the first data block;
step S2023, moving the first data directing pointer from the first start identifier, so that the first data directing pointer sequentially points to start storage addresses of each intermittent fault data in the first data block, and sequentially reading all intermittent fault data stored in the first data block in combination with all start storage addresses pointed by the first data directing pointer until the first end identifier is read; when the intermittent fault data in the first data block are stored, sequentially storing each intermittent fault data according to the storage address of the first data block, and moving the first termination identifier to the storage address where the storage of the intermittent fault data is finished every time one intermittent fault data is stored.
In the embodiment of the present invention, when the front-end detection node stores intermittent failure data, a storage start address of first intermittent failure data may be recorded in metadata information of a first data block as a first start identifier, where the first start identifier is a start storage address of all intermittent failure data stored in the first data block; in addition, every time one intermittent fault data is stored, the front-end detection node can also store the initial storage address of the corresponding intermittent fault data in the metadata information; and, every time the front-end detection node finishes storing one intermittent fault data, the front-end detection node may further record a first termination identifier in the first data block, where the first termination identifier may indicate a termination address where the intermittent fault data is stored, that is, a termination address where the last intermittent fault data is stored in the first data block.
In this way, when the control device analyzes the vehicle status data to be processed, the control device can read the metadata information of the first data block, thereby obtaining a first starting identifier, a first terminating identifier and a starting storage address of each intermittent fault data recorded by the front-end detection node, and creating a first data directing pointer, moving the first data directing pointer from the first start identifier, so that the first data directing pointer points to the starting memory address of each intermittent fault data in the first data block in turn, and sequentially reading all intermittent fault data stored in the first data block in combination with all initial storage addresses pointed by the first data guide pointer until the first termination identifier is read, all intermittent fault data held in the first data block is thus obtained, thereby ensuring the integrity of each intermittent fault data.
Additionally, to accurately identify the respective persistent fault data, in some embodiments, step S204 may include the following sub-steps:
step S2041, reading metadata information of the second data block to obtain a second start identifier and a second end identifier in the second data block; the second start identifier is used for indicating a start address for storing persistent failure data, the second end identifier is used for indicating an end address for storing persistent failure data, and a start storage address of each persistent failure data is further stored in the metadata information of the second data block;
step S2042, a second data guide pointer is created; wherein the second data direction pointer is used for pointing to a starting storage address of persistent fault data in the second data block;
step S2043, moving the second data directing pointer from the second start identifier, so that the second data directing pointer sequentially points to the start storage address of each persistent failure data in the second data block, and sequentially reading all persistent failure data stored in the second data block in combination with all the start storage addresses pointed by the first data directing pointer until the second end identifier is read; when the continuous fault data in the second data block are stored, sequentially storing each continuous fault data according to the storage address of the second data block, and moving the second termination identifier to the storage address where storing the continuous fault data is finished every time one continuous fault data is stored.
In the embodiment of the present invention, a reading manner of the continuous fault data may be a reading manner similar to the reading manner of the intermittent fault data provided in the embodiment of the present invention, and details of the embodiment of the present invention are not repeated herein.
In addition, the implementation manner provided by the embodiment of the invention mainly uses various intermittent fault data of the automobile as objects to send out the first fault reminding indication information, so that a user can pay attention to various faults with short duration on the automobile.
For each continuous fault data detected by the front-end detection node, the embodiment of the invention can also send out second fault reminding indication information aiming at each continuous single battle data, so that a user can pay attention to each fault which lasts for a long time on the automobile.
Therefore, in some embodiments, the new energy vehicle fault data processing method provided by the embodiments of the present invention may further include the following steps:
step S208, receiving an automobile fault indication;
step S209, using the maximum storage address corresponding to the second data block as the initial read address in all the persistent failure data added to the comprehensive failure set;
step S210, responding to the automobile fault indication, and moving the second data guide pointer from the initial reading address to read continuous fault data until the continuous fault data meeting the set termination condition is read; the set termination condition is that the read continuous fault data reaches a third time length;
and step S211, sending out second fault reminding indication information according to the respective fault duration of the read continuous fault data.
In the embodiment of the invention, a user can send an automobile fault indication through some terminal control devices or touch control terminal devices, so as to acquire the continuous fault problem of the new energy automobile.
After receiving the automobile fault indication, the control device may add all the continuous fault data in the comprehensive fault set, use the maximum storage address corresponding to the second data block as an initial read address, and in response to the automobile fault indication, move the second data guide pointer from the initial read address to read the continuous fault data until the continuous fault data meeting the set termination condition is read, so as to send out second fault prompt indication information according to the respective fault durations of the read continuous fault data, for example, display the fault type and the fault start-stop time of each continuous fault data on a display screen of the new energy automobile, so that a user can know the continuous fault problems on the new energy automobile to a certain extent.
In order to reduce the hardware overhead of the control device in reporting the fault information, in some embodiments, step S210 may include the following sub-steps:
step S2101, moving the second data directing pointer to sequentially read each continuous failure data from the second data block and count the accumulated duration of the read continuous failure data until the last continuous failure data stored in the second data block is read;
step S2102 of continuously determining whether the accumulated time length of the read continuous failure data reaches the third time length; when yes, step S2103 is performed; when no, step S2104 is performed;
step S2103, when the accumulated time length of the read continuous fault data reaches the third time length, sending out second fault reminding indication information according to the respective read fault time lengths of the continuous fault data;
step S2104, when the accumulated time length of the read continuous fault data does not reach the third time length until the last continuous fault data is read, continuing to move the second data directing pointer to reversely read each continuous fault data stored in the second data block from the starting read address until the accumulated time length of the read continuous fault data reaches the third time length, and sending second fault reminding indication information according to the read respective fault time lengths of the continuous fault data.
In the embodiment of the invention, the continuous fault data in the continuous fault set are continuously read until the accumulated time of all the read continuous fault data reaches the third time, so that the continuous fault data can be reported in batches, and the hardware consumption of the control equipment is reduced.
In addition, when the step of sending out the first failure warning indication information is implemented, in some embodiments, the step S207 may include the following sub-steps:
step S2071, dividing a first fault data set and a second fault data set from the comprehensive fault set according to the fault type of each fault data; wherein the first failure data set includes at least two first type failures and the second failure data set includes at least two second type failures equal in number to the number of failures of the first failure data set;
in the embodiment of the invention, the fault types corresponding to all the fault data can be configured in advance, for example, all the fault data can be divided into slight faults and serious faults according to the driving safety influence degree on the new energy automobile, for example, the slight faults can be fuse breakage, insufficient refrigerating fluid, battery pack line falling and the like, and the serious faults can be power switch breakage, motor burnout and the like.
In this manner, in performing step S2071, all fault data belonging to a major fault may be classified as a first type fault into a first fault data set, and all fault data belonging to a minor fault may be classified as a second type fault into a second fault data set.
When the first failure data set and the second failure data set are divided, failure data of the same data can be divided in the first failure data set and the second failure data set, and a one-to-one correspondence relationship can be established for the failure data therein, for example, the failure data in the first failure data set and the data in the second failure data set can be sequentially established in a sequence from small to large according to the failure duration.
Step S2072, determining a fault duration level and a comparison fault level corresponding to each first type fault based on the fault duration corresponding to each first type fault and the fault duration corresponding to each second type fault; wherein the fault duration level is a ratio of a fault duration of each of the first type faults to a fault duration of a first type fault having a longest corresponding fault duration in the first fault data set, and the comparison fault level is a ratio of a fault duration of each of the first type faults to a fault duration of a second type fault corresponding to the first type fault in the second fault data set;
in the embodiment of the present invention, a ratio between the time length of each first type fault and the time length of the first type fault corresponding to the fault time length in the first fault data set may be determined, so as to obtain the fault time length level corresponding to each first type fault; in addition, the time length of the first type fault in the first fault data set is compared with the time length of the second type fault corresponding to the second fault data set, so that the comparison fault level of each first type fault is obtained.
Step S2073, determining the first type faults with the relative ratio meeting a second preset threshold value in the first fault data set as target fault data according to the relative ratio between the fault duration level and the comparison fault level corresponding to each first type fault;
in the embodiment of the present invention, after the fault duration level and the comparison fault level corresponding to each first type fault are obtained, a ratio may be made between the fault duration level and the comparison fault level corresponding to each first type fault, a relative ratio between the fault duration level and the comparison fault level corresponding to each first type fault is obtained, and the first type fault whose corresponding ratio satisfies a second preset threshold is determined as the target fault data according to the relative ratio of each first type fault.
Step S2074, for each fault index, based on at least two fault index parameter intervals of the fault index, counting the ratio of the fault data included in each fault index parameter interval in the target fault data;
in the embodiment of the present invention, a plurality of fault indicators may be preset, such as the above-mentioned fault duration, fault duration level, comparison fault level, and the like, and at least two fault indicator parameter sections preset for each fault indicator are used to count a ratio of fault data included in each fault indicator parameter section in the target fault data with respect to all the first type faults.
Step S2075, determining the contribution value of each fault index to the target fault data according to the ratio of the fault data included in each fault index parameter interval in the target fault data;
in the embodiment of the present invention, the ratio of the fault data included in each fault index parameter interval may be directly used as the contribution value of each fault index to the target fault data.
