Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings, not all of them.
Before the technical scheme is elaborated, an application scenario of the technical scheme is introduced to make the technical scheme more clearly understood. In order to guarantee the safety of the vehicle, the vehicle needs to test each grounding point of the vehicle before leaving the factory so as to judge whether the grounding point of the vehicle has potential loop risks of the whole vehicle wire harness when the grounding point of the vehicle becomes loose or falls and other failure conditions occur, and the grounding point with the potential loop risks is detected, so that the potential safety hazard problem of each grounding point is eliminated in the germination stage, and the safety of the vehicle in the using process is improved.
Example one
Fig. 1 is a schematic flow chart of a vehicle abnormality detection method according to an embodiment of the present invention, which is applicable to a situation where whether an abnormality problem of a potential loop exists in a vehicle is detected, and the method may be executed by a vehicle abnormality detection apparatus, where the apparatus may be implemented in the form of software and/or hardware, and the hardware may be an electronic device, such as a mobile terminal or a PC.
As shown in fig. 1, the method includes:
and S110, determining each load and/or controller connected with the current grounding point aiming at each grounding point, and determining the current operation state of each load and/or controller.
When testing potential return circuit risk in the vehicle, mainly when each earthing point of vehicle became invalid, whether still had the current return circuit to whole car pencil and detect. When a grounding point fails, current in the vehicle may flow through the vehicle housing or other nearby grounding points, i.e., when the grounding point fails, a current loop is still present in the line associated with the grounding point. Because the current that can be born by the whole car pencil is limited, when having heavy current to pass in the pencil, the unusual latent return circuit current of vehicle is too big, probably has the condition of circuit spontaneous combustion.
There may be multiple lines associated with each grounding point in the vehicle, and each line is correspondingly connected with a corresponding load or controller, such as a vehicle seat adjuster, a window adjuster, an audio/video player, a vehicle air conditioner, a vehicle controller, and the like. The current grounding point can be understood as a grounding point which is currently detected, and the current operation state can be understood as a state whether each load and/or controller connected with the current grounding point can normally operate or not when the current grounding point fails.
In particular, there are multiple grounding points in a vehicle, and testing of each grounding point in the vehicle is required when testing for potential loop risks of the vehicle. Determining a grounding point which needs to be detected currently, detecting the current grounding point, firstly determining each load and/or controller connected with the current grounding point, and detecting whether each load and/or controller can normally operate currently.
Optionally, the determining, for each grounding point, each load and/or controller connected to the current grounding point, and determining a current operating state of each load and/or controller includes: sending test information to each load and/or controller, and receiving feedback information of each load and/or controller; the test information comprises at least one of message information and pulse information; and determining the running state of each load and/or controller according to the feedback information.
When the operation state of each load and/or controller connected to the current grounding point is detected, a data acquisition instrument, such as a CAN data acquisition instrument, CAN be connected to the bus monitoring port and used for sending test information to each load and/or controller and receiving feedback information of each load and/or controller. The test information can be understood as information sent by the data acquisition instrument to each load and/or controller; the feedback information may be understood as a feedback signal sent by each load and/or controller to the data acquisition instrument, and may be, for example, network message information or pulse information. If the data acquisition instrument can receive the information fed back by each load and/or controller, it indicates that each load and/or controller can still operate normally when the current grounding point fails, that is, when the current grounding point fails, a potential loop is formed between each load and/or controller and other grounding points, and when the potential loop exists in the vehicle, the safety of the vehicle may be affected.
Specifically, in order to test whether each load and/or controller CAN normally operate when the current grounding point of each load and/or controller fails, a CAN data acquisition instrument may be connected to the bus monitoring port, test information may be sent to each load and/or controller by the CAN data acquisition instrument, and the current operating state of each load and/or controller may be determined according to whether feedback information of each load and/or controller CAN be received. Wherein the test information includes at least one of message information and pulse information.
Optionally, the determining the operation state of each load and/or controller according to the feedback information includes: if the feedback information of each load and/or controller is received, determining that the running state of each load and/or controller is a normal state; and if the feedback information of each load and/or controller is not received, determining that the running state of each load and/or controller is an abnormal state.
Specifically, if the feedback information of each load and/or controller can be received, it indicates that the current operation state of each load and/or controller is a normal state; if the feedback information of each load and/or controller cannot be received, the operation state of each load and/or controller is in an abnormal state of being incapable of working.
It should be noted that, under normal conditions, when the current ground point is failed, each load and/or controller connected to the current ground point cannot receive the test information sent by the data acquisition instrument, and cannot send feedback information to the data acquisition instrument. Thus, when feedback information is received for each load and/or controller indicating that a potential loop is present near the current ground point, further potential loop risk testing is required to determine the specific location where the potential loop risk is present.
And S120, determining a target load and/or a target controller from the loads and/or the controllers according to the current running state, and detecting current information of the target load and/or the target controller and a connecting line of the grounding point to obtain a detection result corresponding to each connecting line.
The target load and/or target controller may be understood as a load and/or controller that sends a feedback message to the data acquisition instrument.
Specifically, according to the operating state of each load and/or controller, a target load and/or controller may be determined from each load and/or controller, that is, a load and/or controller that sends feedback information to the data acquisition instrument among each load and/or controller may be used as the target load and/or controller. Then, current information in each line connected with each target load and/or the controller is determined to be detected, and whether current exists in each connecting line is determined.
Optionally, the determining, according to the current operating state, a target load and/or a target controller from the loads and/or the controllers, and performing current information detection on the target load and/or the target controller and a connection line of the ground point to obtain a detection result corresponding to each connection line includes: if the running state of each load and/or controller is a normal state, determining a target load and/or a target controller from each load and/or controller based on the load and/or controller identification of each load and/or controller; and detecting current information of the target load and/or the target controller and a connecting line of the grounding point based on a current detector, and obtaining a detection result corresponding to each connecting line.
The load and/or controller identification may be understood as identification information representing each load and/or controller, such as number information or other unique identification information. The current detector may be understood as a device for detecting current information in each line, and may be a high-precision ammeter, a loop current sensor, a current clamp, or the like. The detection result may be understood as a result obtained by detecting current value information of each line, including magnitude information and direction information of the current value.
Specifically, the same grounding point in the vehicle may be connected to a plurality of loads and/or controllers, and if feedback information of each load and/or controller is received, a target load and/or controller is determined from each load and/or controller according to identification information of each load and/or controller of the feedback information. And then, detecting current value information in the connecting lines of the target load and/or the controller and each connecting point based on the current detector, and determining the current value information in each connecting line, wherein the current value information comprises the magnitude and the current direction of the current.
Optionally, the detecting of the current information of the target load and/or the target controller and the connecting line of the grounding point by the current detector to obtain a detection result corresponding to each connecting line includes: determining line identifications corresponding to the connection lines, and calling preset current intervals corresponding to the line identifications from a pre-stored target mapping table according to the line identifications; and obtaining current value information corresponding to the target load and/or the target controller, and comparing the corresponding current value information based on each preset current interval to obtain a comparison result.
The load and/or controller has several corresponding connecting lines connected to different earthing points, controllers, etc. each connecting line is identified for distinguishing connecting lines. The rated carrying current of each connection line is limited, and the target map can be understood as a map for recording the current value ranges of the respective connection lines and the corresponding current values. The predetermined current interval can be understood as a current value range set according to the rated adapting current of different connecting lines.
Specifically, in order to determine a potential loop corresponding to each target load and/or controller capable of normally operating when the current grounding point fails, a connection line corresponding to each target load and/or controller is determined according to each line identifier. And then determining the rated carrying current corresponding to each connecting line according to a prestored target mapping table, comparing the detected current value of the target load and/or the current value of the connecting line corresponding to the controller with the preset current interval in the target mapping table, and determining whether the current value of each connecting line is in the preset current interval according to the comparison result.
And S130, determining an early warning grade and a detection report according to the detection result, and feeding back.
The early warning level may be understood as a risk level corresponding to each connection line of the target load and/or the controller, and may include a low risk, a medium risk, and a high risk. The detection report can be understood as a report generated based on the detection result of each connection line, and includes information such as the magnitude, direction, and early warning level of the current value of each connection line.
Specifically, the current value information in each connecting line of the target load and/or the controller is detected, the current value information in each connecting line can be obtained, then the current value in each connecting line is compared with a preset current interval, and the early warning grade corresponding to each connecting line can be determined. And generating a detection report based on each piece of information in the detection result, and feeding each detection report back to the client to be displayed for the user.
Optionally, the determining and feeding back the early warning level and the detection report according to the detection result includes: according to the comparison result, if the current value information corresponding to the target load and/or the target controller belongs to a preset current value interval, the early warning level of a connecting line of the target load and/or the target controller and the grounding point is in medium risk; according to the comparison result, if the current value information corresponding to the target load and/or the target controller is larger than a preset current value interval, the early warning level of a connecting line of the target load and/or the target controller and the grounding point is in medium risk; and determining a detection report corresponding to the target load and/or the target controller and a connection line of the grounding point based on the early warning grade, and feeding back.
Specifically, if the current value of the target load and/or the current value of the connection line between the controller and the connection point is within a preset current range, the early warning level corresponding to the connection line is determined as the medium risk. It shows that, although the target load and/or the controller forms a potential loop with the current grounding point when the current grounding point fails, the current value in the loop is within the preset current interval, and thus the safety of the vehicle is not greatly affected. Correspondingly, the early warning grade of the connecting line is determined as the intermediate risk, and the early warning grade can be used for prompting the potential loop in the connecting line for workers, and the workers further judge whether the potential loop problem of the line needs to be processed or not.
And if the current value in the connecting line is larger than the preset current interval, determining the early warning level corresponding to the corresponding connecting line as high risk. It is shown that, when the current grounding point of the target load and/or the controller fails, the target load and/or the controller forms a potential loop through other grounding points, and a large current value is formed in the connection line, which greatly affects the safety of the vehicle. Accordingly, the warning level of the connection line is determined to be a high risk, and a potential loop problem of the connection line needs to be immediately handled by a worker.
And then generating a corresponding detection report based on the detection result, and feeding the detection report back to the client, so that a worker can determine whether the potential loop problem in the vehicle needs to be processed or not through the detection report.
Optionally, if the operating state of each load and/or controller connected to the current ground point is an abnormal state, the early warning level of the connection line between each load and/or controller connected to the current ground point and the current ground point is low.
Specifically, after the data acquisition instrument sends the test information to each load and/or controller, if the feedback information of each load and/or controller is not received, it indicates that each load and/or controller does not form a potential loop through a nearby grounding point when the current grounding point fails. In this case, no potential circuit problems are present in the vehicle, and the risk level of the connection between the respective load and/or controller and the current connection point is determined as low risk.
And similarly, based on the detection result, generating a corresponding detection report according to the detection result so as to feed back the detection report to the staff for the staff to refer.
According to the technical scheme of the embodiment, each load and/or controller connected with the current grounding point is determined aiming at each grounding point, the current running state of each load and/or controller is determined, test information is sent to each load and/or controller under the condition that the current grounding point is invalid, and the running state of each load and/or controller is determined according to whether each load and/or controller feeds back information to the data acquisition instrument or not. And determining a target load and/or a target controller from the loads and/or the controllers according to the current operation state, detecting current information of the target load and/or the target controller and a connecting line of the grounding point to obtain a detection result corresponding to each connecting line, taking each load and/or controller with feedback information as the target load and/or the controller, detecting the current information of the connecting line between the target load and/or the controller and the grounding point to obtain the current value of each connecting line, and comparing the current value of each connecting line with a preset current interval. And determining the early warning grade and the detection report according to the detection result, feeding back, determining the early warning grade of each connecting line according to whether the current value in each connecting line exceeds a preset current interval, generating a corresponding detection report based on the detection result, and feeding back to the client so as to provide reference for workers. The problem of when detecting the potential return circuit in the vehicle based on the manual work, have detection efficiency low and probably appear missing the detection, or detection accuracy is not high is solved, the automatic quick and accurate effect of detecting the potential return circuit risk in the vehicle has been realized.
Example two
In a specific example, in order to detect whether or not a potential loop exists in the vehicle, as shown in fig. 2, a plurality of grounding points exist in the vehicle, and a grounding point that needs to be detected at the present time (i.e., a present grounding point) is first determined for each grounding point. The current grounding point is removed, and a current sensing instrument (namely, a current detector) is installed, wherein the current sensing instrument can comprise instruments such as a high-precision ammeter, a ring current sensor, a current clamp and the like. Then, a CAN data collector (i.e., a data collector) is connected to the bus monitoring port.
In the testing process, network message information (namely, testing information) is sent to each load and/or controller through the CAN data acquisition instrument, and feedback information of each load and/or controller is received through the CAN data acquisition instrument. The operation state of each load and/or controller CAN be determined according to whether each load and/or controller feeds back information to the CAN data acquisition instrument. And determining each load and/or controller of the feedback information as a target load and/or controller, and then detecting current value information in a connecting line between the target load and/or controller and the grounding point based on the current detector. After current value information in each connecting circuit is obtained based on a current detector, corresponding normal ground harness design indexes (namely, a preset current interval) are determined from a target mapping table based on circuit identification, and if the current value in the connecting circuit is in the preset current interval, an early warning grade corresponding to the connecting circuit is determined to be at an intermediate risk. And if the current value in the connecting line exceeds a preset current interval, determining the early warning level corresponding to the connecting line as high risk.
It should be noted that if the feedback information of each load and/or controller is not received, it indicates that each load and/or controller does not form a potential loop through another grounding point when the current grounding point fails, and the early warning level of each load and/or controller may be determined as a low risk.
Then, a corresponding test report is generated based on the test results in each connection line, see fig. 3, and fed back to the operator. In the detection report, a ground point at which an abnormality occurs in the vehicle may be included, and taking G48 bond point (i.e., the current ground point) as an example, each load and/or controller connected to the current ground point includes a left front threshold usher lamp, a right front seat adjustment switch, a seat environment controller, a driver seat ventilation motor, a left front seat heater, a right front door controller, a right front door lock motor, a right side outside rear view mirror, and a right side atmosphere lamp controller. When the G48 bonding point fails, the left front threshold welcome lamp forms a potential loop through the panoramic image shell, and current flow information of each connecting line is included in the detection report. Based on the detection report, the staff can determine the abnormal connecting line, perform detailed detection on the abnormal connecting line, and locate the abnormal grounding point for further processing, such as replacement or maintenance.
According to the technical scheme of the embodiment, each load and/or controller connected with the current grounding point is determined aiming at each grounding point, the current running state of each load and/or controller is determined, test information is sent to each load and/or controller under the condition that the current grounding point is invalid, and the running state of each load and/or controller is determined according to whether each load and/or controller feeds back information to the data acquisition instrument or not. And determining a target load and/or a target controller from the loads and/or the controllers according to the current operation state, detecting current information of the target load and/or the target controller and a connecting line of the grounding point to obtain a detection result corresponding to each connecting line, taking each load and/or controller with feedback information as the target load and/or the controller, detecting the current information of the connecting line between the target load and/or the controller and the grounding point to obtain the current value of each connecting line, and comparing the current value of each connecting line with a preset current interval. And determining the early warning grade and the detection report according to the detection result, feeding back, determining the early warning grade of each connecting line according to whether the current value in each connecting line exceeds a preset current interval, generating a corresponding detection report based on the detection result, and feeding back to the client so as to provide reference for workers. The problem that when a potential loop in a vehicle is detected manually, detection efficiency is low, detection is possibly missed, or detection accuracy is low is solved, and the effect of automatically, quickly and accurately detecting the potential loop risk in the vehicle is achieved.
