Detailed Description
The technical solutions of the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application, and although exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the application to those skilled in the art.
In various embodiments of the present invention, it should be understood that the sequence numbers of the following processes do not mean the order of execution, and the order of execution of the processes should be determined by the functions and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.
The signal processing method, the device, the electronic equipment and the vehicle provided by the embodiment of the application are described in detail through specific embodiments and application scenes thereof with reference to the accompanying drawings.
Referring to fig. 2, fig. 2 is a flowchart illustrating steps of a signal processing method according to an exemplary embodiment:
Step 101, acquiring the number of signals of the abnormal event to be triggered and the data length of each signal.
In the embodiment of the invention, the Internet of vehicles collects and transmits a large number of signals with low sampling frequency requirements to the cloud for limited CAN network resources, bandwidth resources and cloud data storage resources, wherein the data transmission channel not only transmits normal data but also transmits and reports data of an abnormal event, the signals in the CAN are fixedly arranged in the prior art, each signal is required to be transmitted in a high-frequency mode, so that the Internet of vehicles CAN collect the corresponding signals when the abnormal event occurs, but the mode wastes the bandwidth and flow of data transmission very much, therefore, the signals are grouped based on the abnormal event in the embodiment of the invention, and the signals are collected after the abnormal event occurs, thereby saving resources. In order to group the signals based on the abnormal events, the number of the signals of the abnormal events to be triggered and the data length of each signal need to be acquired first, so that the total data storage space occupied by the signals of each abnormal event can be determined conveniently according to the information.
Step 102, grouping the data storage spaces of the controller area network identifier according to a preset size to obtain a plurality of grouped data storage spaces.
In the embodiment of the invention, in order to realize the data transmission of a plurality of events by using a small amount of CAN transmission resources, the data storage spaces of the controller area network identifiers are grouped according to the preset size to obtain a plurality of grouped data storage spaces, so that when the subsequent abnormal events are stored according to the grouped data storage spaces, the data storage space of one controller area network identifier CAN store a plurality of abnormal events for the abnormal event with smaller occupied space. The preset size may be set according to one frame CANFD (data length of 64 bytes is a group), or may be set according to other manners, which are not limited herein.
Step 103, distributing a packet data storage space for the signals of the abnormal events to be triggered based on the number of the signals of the abnormal events to be triggered and the data length of each signal, wherein a preset space is distributed in the packet data storage space for adding event identification of the abnormal events to be triggered.
In the embodiment of the invention, the total data storage space occupied by the signals of the to-be-triggered abnormal events is determined through the number of the signals of the to-be-triggered abnormal events and the data length of each signal, then the grouping space which is larger than or equal to the total data storage space is selected from the grouping data storage space, and the grouping data storage space is allocated for the signals of the to-be-triggered abnormal events, wherein, in order to normally identify the abnormal events later, a preset space is allocated in the grouping data storage space for adding event identifications of the to-be-triggered abnormal events, for example, as shown in fig. 3, different abnormal events are stored in the controller local area network identification-1, and the signal arrangement of each abnormal event is different. It is therefore necessary to confirm the event data in the current transmission channel by adding the event identification ID at the beginning position of position byte 1 in the controller area network identification-1. For example, when the event representation ID is 1, data of the abnormal event 1 is transmitted, and the signal arrangement from byte 2 is all data signals belonging to the abnormal event 1. The event identification ID may be placed at any position of the controller lan identification, so long as in the process of data analysis, signal analysis can be performed according to the analysis rule of the event response by judging the event identification ID.
It should be noted that, in the embodiment of the present invention, besides allocating occupied data storage space for an abnormal event to be triggered, a flag bit is set, because the abnormal event does not occur at any time, so that a signal of the abnormal event exists at any time, and only after the abnormal event is triggered, a corresponding signal is filled in a pre-allocated space, so that subsequent acquisition and transmission are facilitated, and the triggering of the abnormal event needs to be determined.
Determining a plurality of abnormal events to be triggered through historical data and expert knowledge of the Internet of vehicles;
Setting a condition-triggered judgment logic and a mark bit for marking event triggering for each abnormal event to be triggered in advance;
Under the condition that the abnormal event is triggered through the judging logic triggered by the condition, controlling the flag bit triggered by the marked event, wherein the flag bit is used for indicating that the abnormal event is triggered;
And under the condition that the abnormal event is not triggered through the judgment logic triggered by the condition, the zone bit for controlling the occurrence of the marked event is in a default initial state.
The above condition triggering judgment logic and the Flag bit triggered by the marked event are set for each abnormal event to be triggered, so the Flag bit identification corresponding to each abnormal event to be triggered is in one-to-one correspondence, as shown in fig. 4, by way of example, the Flag bit set for the abnormal event 1 is Flag1, the Flag bit set for the abnormal event 2 is Flag2, the Flag bit set for the abnormal event n is Flag n, when it is determined that the abnormal event 1 meets the triggering condition, flag1 is set, and then if it is determined that the data of the abnormal event 1 has been sent, the Flag1 is controlled to restore the initial state, and correspondingly, the abnormal event 2 and the abnormal event n also determine the state transformation of the Flag bit according to the mode of the abnormal event 1.
Further, because there are a plurality of abnormal events, and the occurrence of the abnormal events is uncontrolled, a plurality of abnormal events may occur simultaneously, but the data transmission channel can only transmit data of one event at a time, and the integrity of the transmitted data is guaranteed once, then the priority of event transmission needs to be judged, so that the data of the event with high priority is transmitted in advance. When the position of the marker of the abnormal event is determined, assigning a predefined target value as a priority value of the abnormal event; when the flag bit of the abnormal event is not set, the target Value is assigned to 0, wherein the target Value can be identified by Value, and the method specifically comprises the following steps:
Presetting a priority score for each abnormal event to be triggered;
Acquiring event identifications of each abnormal event to be triggered, binding priority scores with the event identifications of the corresponding abnormal events to be triggered, and generating a priority score assignment table;
Under the condition that the marker bit of the abnormal event is in a default initial state, the target value of the abnormal event is assigned to 0;
Under the condition that a first abnormal event with a flag bit is detected, acquiring an event identifier of the first abnormal event;
Retrieving in a priority score assignment table through the event identification of the first abnormal event to obtain a first priority score bound with the event identification of the first abnormal event;
the target value of the first abnormal event is assigned as a first priority score.
And 104, acquiring an event identifier of the target abnormal event and a controller local area network identifier under the condition that the data transmission channel is detected to be idle and the target abnormal event is triggered.
When the data transmission channel is idle, the preemption arbitration module works, wherein the preemption arbitration module can be triggered when the abnormal event is determined to be triggered (the flag bit is set), the event identification of the target abnormal event and the controller local area network identification are sent to the preemption arbitration module at the moment, signal data of the target abnormal event to be transmitted can be conveniently found out according to the event identification and the controller local area network identification, but the flag bit only triggers the preemption arbitration module to store information into the preemption arbitration module, and only when the data transmission channel is idle, the preemption arbitration module storing the event identification of the target abnormal event and the controller local area network identification starts to work, and the preemption data transmission channel specifically comprises:
Under the condition that the triggering of the target abnormal event is detected, acquiring an event identifier of the target abnormal event and a controller local area network identifier;
the event identification of the target abnormal event and the controller local area network identification are sent to a downstream preemption arbitration module;
And under the condition that the data transmission channel is detected to be idle, controlling the preemption arbitration module to work.
It should be noted that, since the data transmission channel can only transmit data of one event at a time, and the integrity of the transmitted data is ensured at a time, it is necessary to determine the priority of event transmission, so that the data of the event with high priority is transmitted in advance, therefore, after the preemption arbitration module preempting the data transmission channel, it is also necessary to determine the number of the abnormal events existing in the preemption arbitration module, if only one event has no need of determining the priority, it is necessary to directly obtain the event identifier and the controller local area network identifier of the abnormal event, so that the abnormal event preempting the data transmission channel, if more than one event has need of determining the priority, it is necessary to select the abnormal event with the highest priority as the target abnormal event to be transmitted, and obtain the event identifier and the controller local area network identifier of the target abnormal event, and the specific implementation steps include:
under the condition that the data transmission channel is detected to be idle, acquiring the number of the first abnormal events and a first priority score assigned by the first abnormal events;
Under the condition that the number of the first abnormal events is equal to 1, determining the first abnormal events as target abnormal events, and acquiring event identifications and controller local area network identifications of the target abnormal events;
Under the condition that the number of the first abnormal events is larger than 1, the first priority scores are ranked in the order from large to small;
determining the priority order of the first abnormal event according to the sequencing result;
And selecting the first abnormal event with the highest priority from the priority sequence as a target abnormal event, and acquiring an event identifier of the target abnormal event and a controller local area network identifier.
When the data transmission channel is idle, the preemption arbitration module works, if the number of the first abnormal events is greater than 1 at this time, a maximum value is required to be judged (the larger the set rule is, the higher the priority is indicated), and as shown in fig. 5, for example, the data transmission channel is idle and the preemption arbitration modules are triggered by the abnormal events 1,2 and n, at this time, the preemption arbitration module judges the target values 1,2 and n, and the current idle channel resource is given to the event with the highest priority in the triggering of the current abnormal event.
Step 105, obtaining the data signal of the target abnormal event through the event identification of the target abnormal event and the controller area network identification, and controlling the data signal of the target abnormal event to occupy the data transmission channel in the idle state.
After the event identification of the target abnormal event and the controller local area network identification are acquired in the embodiment of the invention, the data signal of the corresponding target abnormal event can be searched according to the information, the information is transmitted through the data transmission channel, and when the data transmission channel starts to transmit data, the preemption arbitration module is controlled to stop working, so that the integrity of the transmitted data is ensured, the abnormal event currently occupying the data transmission channel can be ensured to complete the data transmission, and the preemption arbitration module can continue working after the data transmission channel is idle again, and the method comprises the following specific steps:
Controlling the preemption arbitration module to stop working;
