S102, when the state information meets the triggering condition, determining a subsystem to be adjusted in the system to be monitored and the target acquisition frequency of the subsystem to be adjusted.
In this embodiment, that the state information satisfies the trigger condition means that the state information matches the trigger condition, or the state information is the same as the trigger condition, or the state information includes the trigger condition. In this embodiment, the process of the system monitoring apparatus executing step 102 may specifically be that, when the state information satisfies the trigger condition, the trigger condition list is queried according to the trigger condition, and the subsystem to be adjusted is determined; and determining the target acquisition frequency of the type to which the trigger condition belongs as the target acquisition frequency of the subsystem to be adjusted. And meanwhile, when the state information meets the trigger condition, acquiring the state information of the subsystem to be adjusted from the moment according to the target acquisition frequency. Wherein, the trigger condition list includes: the trigger condition, the type to which the trigger condition belongs, the target acquisition frequency of each type, the subsystem corresponding to the trigger condition, and the state information to be acquired in the subsystem according to the target acquisition frequency are shown in table 1.
Taking the class I trigger condition, and the subsystem to be adjusted is the ACC subsystem as an example, before the trigger condition is satisfied, the frequency of acquiring the state information of the ACC subsystem is 1/1S, when the class I trigger condition appears at 3.5S, the state information is not acquired at 3.5S, the state information of the ACC subsystem is acquired according to 1/1S from 3.5S, and the acquisition time sequence is 1S, 2S, 3S, 3.5S, 4.5S, and 5.5S … ….
Taking class II triggering conditions and an ACC (adaptive control center) subsystem as an example, before the triggering conditions are met, the frequency of acquiring the state information of the ACC subsystem is 1 time/1 s; when a fault occurs at the moment of 3.2s and the class II triggering condition is met, acquiring the state information of the ACC subsystem at the frequency of 50 times/1 s from the moment of 3.2 s; and when the fault is recovered at the time of 5.4s and the class II triggering condition is not met, acquiring the state information of the ACC subsystem at the frequency of 1/1 s from the time of 5.4 s. The collection time sequence is 1s, 2s, 3s, 3.2s (failure time), 3.22s, 3.24s, 3.26s … … 5.34.34 s, 5.36s, 5.38s, 5.40s, 6.40s, and 7.40s … ….
S103, adjusting the initial acquisition frequency of the subsystem to be adjusted to a target acquisition frequency, and acquiring the state information of the subsystem to be adjusted according to the target acquisition frequency.
In this embodiment, for different subsystems in the system to be monitored, the system monitoring device may set different initial acquisition frequencies for the different subsystems according to the importance of the state information of the subsystems. For example, the state information with higher importance, the initial acquisition frequency of the corresponding subsystem may be higher; for state information with lower importance, the initial acquisition frequency of the corresponding subsystem can be lower. Correspondingly, under the condition that different initial acquisition frequencies are set for different subsystems, different target acquisition frequencies can be set for different subsystems according to the state information and the trigger condition.
Further, on the basis of the foregoing embodiment, after step 103, the method may further include: and when the state information of the subsystem to be adjusted does not meet the trigger condition, adjusting the acquisition frequency of the subsystem to be adjusted to the initial acquisition frequency.
Specifically, if the acquisition frequency of the subsystem to be adjusted is adjusted to the target acquisition frequency before, the type I trigger condition is satisfied, and the condition that the trigger condition is not satisfied here means that the type I trigger condition is not satisfied or various types of trigger conditions are not satisfied, that is, when the trigger condition for adjusting the acquisition frequency of the subsystem to be adjusted is not satisfied before, the acquisition frequency of the subsystem to be adjusted is adjusted to the initial acquisition frequency.
The system monitoring method of the embodiment of the invention obtains the state information of the system to be monitored; when the state information meets the triggering condition, determining a subsystem to be adjusted in the system to be monitored and the target acquisition frequency of the subsystem to be adjusted; adjusting the initial acquisition frequency of the subsystem to be adjusted to a target acquisition frequency, and acquiring state information of the subsystem to be adjusted according to the target acquisition frequency, wherein the acquisition frequency is increased when a fault occurs, for example; for example, when the system runs normally, the acquisition frequency is reduced, and the probability of faults and the like is relatively low, so that the storage space occupied by the acquired state information can be effectively reduced, and the acquisition efficiency under the conditions of faults and the like is improved.
Fig. 2 is a schematic flow chart of another system monitoring method according to an embodiment of the present invention, as shown in fig. 2, based on the embodiment shown in fig. 1, the method further includes the following steps:
and S104, aiming at each subsystem in the system to be monitored, when the state information of the subsystem meets the trigger condition, acquiring the target state information acquired when the trigger condition is met.
And S105, marking the target state information according to the type of the trigger condition and/or the trigger condition.
In this embodiment, in the first implementation scenario, the system monitoring apparatus may set a flag for each piece of data in the target status information, so as to distinguish the data. In a second implementation scenario, the system monitoring device may add markers before and after the target status information to distinguish. Correspondingly, the process of the system monitoring apparatus to execute step 105 may specifically be that, according to the type of the trigger condition and/or the trigger condition, a start mark is added before the target state information; an end marker is added after the target state information.
In this embodiment, different flags may be set for different status information that satisfies the trigger condition; different marks can be set for different trigger conditions; different flags can also be set for different subsystems to be adjusted. When setting the flag, the flag may be set with reference to any one or more of the following parameters: the state information meeting the triggering condition, the triggering condition and the subsystem to be adjusted.
And S106, storing the marked target state information.
In this embodiment, in a first implementation scenario, for each subsystem in a system to be monitored, a system monitoring device may acquire state information acquired according to an initial acquisition frequency of the subsystem, mark target state information according to the target state information acquired according to a target acquisition frequency, combine the marked target state information and the state information acquired according to the initial acquisition frequency, sort the target state information according to time, and locally store and/or report the combined state information to a cloud, thereby facilitating subsequent retrieval.
In this embodiment, in a second implementation scenario, for each subsystem in the system to be monitored, the system monitoring apparatus may acquire target state information acquired when the state information of the subsystem meets a trigger condition, and store the target state information in the first storage location and/or report the target state information to the third storage location in the cloud; when the state information of the subsystem does not meet the triggering condition, the state information of the subsystem is stored to the second storage position and/or reported to the fourth storage position of the cloud end, and storage is distinguished, so that subsequent calling is facilitated.
Under the condition that the system monitoring device locally stores and reports the acquired state information to the cloud, the system monitoring device can firstly store the state information and then periodically report the stored state information to the cloud; and/or when the stored state information meets a threshold value, reporting to the cloud.
In addition, it should be noted that the frequency of reporting the stored state information to the cloud end by the system monitoring device may be adjusted according to whether the state information meets the trigger condition. For example, when the status information satisfies the class II trigger condition, the reporting frequency is adjusted to 50 times/1 s.
For each subsystem, the process of acquiring and storing the state information by the system monitoring device can be specifically that when the state information of the subsystem does not meet the trigger condition, the state information of the subsystem is acquired and stored according to the initial acquisition frequency; when the subsystem state information meets various trigger conditions, adding an initial mark after the stored state information, and starting to acquire and store the target state information of the subsystem according to the target acquisition frequency by taking the time point when the state information meets the I-type trigger conditions as a starting point; and when the target state information does not meet various trigger conditions, adding an end mark after the target state information is stored, and then starting to acquire and store the state information of the subsystem according to the initial acquisition frequency by taking the time point at which the target state information does not meet the I-type trigger conditions as a starting point.
If the vehicle is powered off within 30s after the state information meets the class III triggering condition, the system monitoring device can store the 30s state information before the time point when the state information meets the class III triggering condition until the state information of the vehicle powered off is all stored.
The system monitoring method of the embodiment of the invention obtains the state information of the system to be monitored; when the state information meets the triggering condition, determining a subsystem to be adjusted in the system to be monitored and the target acquisition frequency of the subsystem to be adjusted; adjusting the initial acquisition frequency of the subsystem to be adjusted to a target acquisition frequency, and acquiring state information of the subsystem to be adjusted according to the target acquisition frequency, wherein the acquisition frequency is increased when a fault occurs, for example; for example, when the system operates normally, the acquisition frequency is reduced, and the probability of faults and the like is relatively low, so that the storage space occupied by the acquired state information can be effectively reduced, in addition, when the state information is stored, the target state information acquired according to the target acquisition frequency is firstly marked and then stored, so that when the state information is called, the corresponding state information can be directly acquired according to the mark, and the analysis efficiency of faults and the like is improved.

Correspondingly, under the condition that different initial acquisition frequencies are set for different subsystems, different target acquisition frequencies can be set for different subsystems according to the state information and the trigger condition.
Further, on the basis of the above embodiment, the adjusting module 33 is further configured to adjust the acquisition frequency of the subsystem to be adjusted to the initial acquisition frequency when the state information of the subsystem to be adjusted does not satisfy the trigger condition.
Specifically, if the acquisition frequency of the subsystem to be adjusted is adjusted to the target acquisition frequency before, the type I trigger condition is satisfied, and the condition that the trigger condition is not satisfied here means that the type I trigger condition is not satisfied or various types of trigger conditions are not satisfied, that is, when the trigger condition for adjusting the acquisition frequency of the subsystem to be adjusted is not satisfied before, the acquisition frequency of the subsystem to be adjusted is adjusted to the initial acquisition frequency.
The system monitoring device of the embodiment of the invention acquires the state information of the system to be monitored; when the state information meets the triggering condition, determining a subsystem to be adjusted in the system to be monitored and the target acquisition frequency of the subsystem to be adjusted; adjusting the initial acquisition frequency of the subsystem to be adjusted to a target acquisition frequency, and acquiring state information of the subsystem to be adjusted according to the target acquisition frequency, wherein the acquisition frequency is increased when a fault occurs, for example; for example, when the system runs normally, the acquisition frequency is reduced, and the probability of faults and the like is relatively low, so that the storage space occupied by the acquired state information can be effectively reduced, and the acquisition efficiency under the conditions of faults and the like is improved.
With reference to fig. 4, on the basis of the embodiment shown in fig. 3, the apparatus may further include: and the storage module 34 is configured to store the acquired state information of the system to be monitored.
The storage module 34 may include: an acquisition unit 341, a marking unit 342, and a storage unit 343.
The acquiring unit 341 is configured to, for each subsystem in the system to be monitored, acquire target state information acquired when the state information of the subsystem meets a trigger condition;
a marking unit 342, configured to mark the target state information according to a type of the trigger condition and/or the trigger condition;
a storage unit 343 configured to store the marked target state information;
the storage unit 343 is further configured to directly store the acquired state information of the subsystem when the state information of the subsystem does not meet the trigger condition.
In this embodiment, in the first implementation scenario, the system monitoring apparatus may set a flag for each piece of data in the target status information, so as to distinguish the data. In a second implementation scenario, the system monitoring device may add markers before and after the target status information to distinguish. Correspondingly, the marking unit 342 may be specifically configured to add a start mark before the target state information according to the type of the trigger condition and/or the trigger condition; an end marker is added after the target state information.
In this embodiment, different flags may be set for different status information that satisfies the trigger condition; different marks can be set for different trigger conditions; different flags can also be set for different subsystems to be adjusted. When setting the flag, the flag may be set with reference to any one or more of the following parameters: the state information meeting the triggering condition, the triggering condition and the subsystem to be adjusted.
In this embodiment, in a first implementation scenario, for each subsystem in a system to be monitored, a system monitoring device may acquire state information acquired according to an initial acquisition frequency of the subsystem, mark target state information according to the target state information acquired according to a target acquisition frequency, combine the marked target state information and the state information acquired according to the initial acquisition frequency, sort the target state information according to time, and locally store and/or report the combined state information to a cloud, thereby facilitating subsequent retrieval.
In this embodiment, in a second implementation scenario, for each subsystem in the system to be monitored, the system monitoring apparatus may acquire target state information acquired when the state information of the subsystem meets a trigger condition, and store the target state information in the first storage location and/or report the target state information to the third storage location in the cloud; when the state information of the subsystem does not meet the triggering condition, the state information of the subsystem is stored to the second storage position and/or reported to the fourth storage position of the cloud end, and storage is distinguished, so that subsequent calling is facilitated.
Under the condition that the system monitoring device locally stores and reports the acquired state information to the cloud, the system monitoring device can firstly store the state information and then periodically report the stored state information to the cloud; and/or when the stored state information meets a threshold value, reporting to the cloud.
In addition, it should be noted that the frequency of reporting the stored state information to the cloud end by the system monitoring device may be adjusted according to whether the state information meets the trigger condition. For example, when the status information satisfies the class II trigger condition, the reporting frequency is adjusted to 50 times/1 s.
For each subsystem, the process of acquiring and storing the state information by the system monitoring device can be specifically that when the state information of the subsystem does not meet the trigger condition, the state information of the subsystem is acquired and stored according to the initial acquisition frequency; when the subsystem state information meets various trigger conditions, adding an initial mark after the stored state information, and starting to acquire and store the target state information of the subsystem according to the target acquisition frequency by taking the time point when the state information meets the I-type trigger conditions as a starting point; and when the target state information does not meet various trigger conditions, adding an end mark after the target state information is stored, and then starting to acquire and store the state information of the subsystem according to the initial acquisition frequency by taking the time point at which the target state information does not meet the I-type trigger conditions as a starting point.
If the vehicle is powered off within 30s after the state information meets the class III triggering condition, the system monitoring device can store the 30s state information before the time point when the state information meets the class III triggering condition until the state information of the vehicle powered off is all stored.
Further, with reference to fig. 5, on the basis of the embodiment shown in fig. 3 or fig. 4, the apparatus may further include: the reporting module 35 is configured to report the acquired state information of the system to be monitored to a cloud; or after the collected state information of the system to be monitored is stored, reporting the stored state information to the cloud.
