Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The embodiment of the invention provides a vehicle running early warning system which can be used for early warning scenes when a running vehicle has a dangerous event.
Specifically, the vehicle can be provided with vehicle-mounted equipment for data acquisition, and in the driving process of the vehicle, the vehicle-mounted equipment can acquire the data in the driving process of the vehicle and send the acquired data to a database of the server. The server side can call a preset alarm information generation model based on data of vehicles in the database, can determine vehicles with dangerous events and generate corresponding alarm information, and then transmits the generated alarm information to the early warning system. Vehicle identification, event type and alarm time may be included in the alarm information. The vehicle identification is the identification of the vehicle corresponding to the alarm information, the event type represents the type of the dangerous event of the vehicle, and the alarm time represents the time for sending the data of the vehicle to the database, which is equivalent to the time for the dangerous event of the vehicle.
In the embodiment of the invention, the vehicle identifier may specifically be a license plate number of the vehicle, and the alarm information may further include parameters such as information of an enterprise to which the vehicle belongs, for example, a highest level of the enterprise to which the vehicle belongs. The vehicle is generally operated according to a driver and an ADAS (Advanced Driving Assistance System), so the event types may specifically include eye closing, telephone calling, smoking, yawning, shading deviation, distraction, pedestrian warning, lane deviation warning, vehicle distance too close warning, preceding vehicle collision warning, and the like.
According to the method and the device, based on analysis of the vehicle accident and the occurrence condition of the vehicle dangerous event, the fact that some types of dangerous events have relevance can be determined, and for the same vehicle, if the dangerous events corresponding to the relevant event types occur successively, namely an accident chain is formed, the possibility that the vehicle has the accident is higher. For example, when a vehicle runs, the possibility of an accident of the vehicle when the eyes of a driver are closed and the vehicle deviates from the vehicle, so that the closed eyes and the vehicle deviation early warning have correlation, the closed eyes and the vehicle deviation early warning can form an accident chain, and a mapping relation between the closed eyes and the vehicle deviation early warning can be established in the embodiment of the invention.
It should be noted that, in the embodiment of the present invention, the early warning system may be disposed at the server, or may be disposed independently from the server.
The embodiment of the invention provides a vehicle running early warning method, which can be executed by an early warning system and comprises the following steps of:
s101: and receiving the current alarm information, and acquiring the vehicle identification, the event type and the alarm time included in the current alarm information.
The current alarm information represents the alarm information currently received by the early warning system and is the alarm information of the dangerous event in the driving process of the vehicle. In the step, the vehicle identification, the event type and the alarm time included in the current alarm information are obtained so as to perform subsequent analysis processing and early warning.
S102: and positioning historical alarm information in a corresponding time period based on the alarm time, and judging whether the historical alarm information with the vehicle identification is included.
In the embodiment of the invention, whether the dangerous events of the associated event types occur continuously or not needs to be analyzed based on the historical alarm information and the current alarm information, and the historical alarm information in the corresponding time period is positioned based on the alarm time in all the steps, namely the historical alarm information of which the alarm time is in the time period corresponding to the current alarm information is positioned.
Because the associated event type is corresponding to the continuous occurrence of the dangerous event, which indicates that the occurrence time of the two dangerous events is relatively close, in this step, a corresponding time period is determined based on the alarm time of the current alarm information, and then historical alarm information with the alarm time in the time period is positioned for analysis, so as to determine whether the dangerous event of the associated event type is continuously occurring.
The manner of determining the corresponding time period based on the alarm time may be determined based on the alarm time, and specifically, the determination of the preset time period before and/or after the alarm time as the time period corresponding to the alarm time may be configured. The value of the preset time period can be set according to requirements, such as 5 minutes. For example, the preset time period is set to 5 minutes, the alarm time of the current alarm information is 1 month, 1 day 23: 59, the specific value of the time period corresponding to the alarm time may be determined according to the configuration, and may be: 1 month, 1 day 23: 54 to 1 month, 1 day 23: time period between 59, 1 month, 1 day 23: 59 to 1 month, 2 days 00: 04, or 1 month, 1 day, 23: 56 to 1 month, 2 days 00: the time period between 01, etc.
The required historical alarm information, namely the historical alarm information with the event type possibly associated with the event type of the current alarm information, can be positioned based on the time period corresponding to the alarm time. In the embodiment of the invention, the historical alarm information can be stored in the database, and each historical alarm information comprises the alarm time, so that the historical alarm information can be positioned. After the historical alarm information is located, whether the historical alarm information with the vehicle identifier is included or not can be judged, namely whether the alarm information including the vehicle identifier in the current alarm information exists in the located historical alarm information or not is judged, so that whether dangerous events of related event types continuously occur in the same vehicle or not is judged.
It should be noted that the historical alarm information includes a vehicle identifier included in the current alarm information, which indicates that the historical alarm information and the current alarm information are for the same vehicle.
S103: if not, sending an early warning message to the vehicle corresponding to the vehicle identification based on the first early warning program; if so, acquiring the event type of the historical alarm information with the vehicle identification, judging whether the event type of the historical alarm information and the event type of the current alarm information have a mapping relation, if so, sending an early warning message to the vehicle corresponding to the vehicle identification based on a second early warning program, and if not, sending the early warning message to the vehicle corresponding to the vehicle identification based on a first early warning program.
If not, it is indicated that the located historical information does not include the vehicle identifier in the current alarm information, that is, no alarm information for the vehicle corresponding to the current alarm information occurs in the time period corresponding to the alarm time of the current alarm information, and a situation that dangerous events of associated event types continuously occur does not occur, so that it can be determined that the dangerous event corresponding to the current alarm information is an independent event, and an early warning message can be sent to the vehicle corresponding to the vehicle identifier based on the first early warning program. If yes, it is indicated that alarm information including a vehicle identifier in the current alarm information exists in the located historical information, that is, alarm information for a vehicle corresponding to the current alarm information exists in a time period corresponding to the alarm time of the current alarm information, that is, it is indicated that a scene in which dangerous events of associated event types may occur continuously for the vehicle corresponding to the current alarm information is possible, so that in this step, an event type of the historical alarm information having the vehicle identifier can be obtained to determine whether the event type of the historical alarm information and the event type of the current alarm information have a mapping relationship, and further determine whether dangerous events of the associated event types occur continuously for the vehicle corresponding to the current alarm information.
It should be noted that, because there may be a plurality of pieces of history alarm information with vehicle identifiers in the current alarm information in the located history alarm information, at this time, the history alarm information with the alarm time closest to the alarm time of the current alarm information may be determined as the target alarm information, so as to analyze whether the event type of the target alarm information is associated with the event type of the current alarm information. The process of obtaining the event type of the history alarm information with the vehicle identifier in this step may specifically be performed as follows: and acquiring the alarm time of each piece of historical alarm information with the vehicle identification to determine the target alarm information closest to the alarm time of the current alarm information, and further acquiring the event type of the target alarm information.
In the process of judging whether the event type of the historical alarm information and the event type of the current alarm information have the mapping relation, if so, the event type of the historical alarm information is related to the event type of the current alarm information, namely, for the vehicle corresponding to the current alarm information, dangerous events of the related event types continuously occur, and the probability of accidents occurring during vehicle running is improved, so that an early warning message can be sent to the vehicle corresponding to the vehicle identification based on a second early warning program; if not, the event type of the historical alarm information is not associated with the event type of the current alarm information, namely, for the vehicle corresponding to the current alarm information, the dangerous event of the associated event type does not continuously occur, at this moment, the dangerous event corresponding to the current alarm information can be taken as an independent event, namely, the early warning message can be sent to the vehicle corresponding to the vehicle identifier based on the first early warning program.
It should be noted that, in the embodiment of the present invention, the second warning program and the first warning program are both preset, and since the probability of an accident occurring during vehicle driving is increased when a dangerous event of a related event type continuously occurs, the warning level of the second warning program is usually higher than that of the first warning program, for example, the second warning program may be set to contact a driver for warning through a telephone, and the first warning program may be set to send a message to the driver for warning.
For the first warning program, risk levels may also be classified based on event types in the embodiment of the present invention, for example, a call, a smoke, and a blocking deviation are set as high risk level events, yawning and distractions are set as medium risk level events, eyes are closed, pedestrian lane deviation warning is performed, and a vehicle distance is too close to a low risk level event, and corresponding warning programs are set for each risk level. So when early warning is carried out based on first early warning program, can judge the risk level that the event type of current alarm information corresponds earlier, and then early warning is carried out with the early warning program that this risk level corresponds, specifically can carry out: and determining a target risk level corresponding to the event type of the current alarm information based on the corresponding relation between the preset event type and the risk level, and sending an early warning message to the vehicle corresponding to the vehicle identification by using an early warning program based on the target risk level.
For the second early warning program, in the embodiment of the invention, different early warning programs can be set based on the number of the alarm information with the vehicle identifier in the current alarm information in the historical alarm information or the frequency of the occurrence of the alarm information. For example, the embodiment of the present invention may set two frequency thresholds
(
Is less than
) To divide three frequency intervals, which are greater than or equal to 0 and less than
Is greater than or equal to
And is less than
Greater than or equal to
And corresponding early warning programs are set for each frequency interval, so that after the associated event program early warning is determined, the occurrence frequency of the warning information with the vehicle identification included by the current warning information in the historical warning information can be further calculated and positioned, and the corresponding early warning programs are determined to carry out early warning by combining with the frequency threshold. The frequency threshold may be determined based on the frequency of occurrence of historical alarm information, and typically the frequency threshold should not be less than e,
wherein, KaIndicating the average number of alarm messages received per hour in a predetermined period of time, DcRepresenting the total number of vehicles traveling within a preset time period,if the total number of the running vehicles in the preset time period varies, the maximum value and the minimum value of the total number of the running vehicles in the time period can be taken to calculate the average value of the running vehicles, so that the total number of the running vehicles is determined.
For another example, the embodiment of the present invention may set two quantity thresholds to partition each quantity interval, and set a corresponding early warning program for each quantity interval, so after determining that the early warning is based on the correlated event program, the quantity of alarm information with the vehicle identifier in the current alarm information in the historical alarm information can be further calculated and located, and then the corresponding early warning program is determined to perform early warning in combination with the quantity interval, which may be specifically implemented as: the method comprises the steps of calculating the information quantity of alarm information with vehicle identification in historical alarm information, determining a target quantity interval to which the information quantity belongs based on a preset quantity interval, and sending early warning information to a vehicle corresponding to the vehicle identification based on an early warning program corresponding to the target quantity interval.
It should be noted that, in the embodiment of the present invention, a risk level may also be set for each associated event type, for example, associated event types formed by combining four event types, such as smoke extraction, call making, front vehicle collision, and lane offset, in pairs correspond to the same risk level, and associated event types formed by combining the other event types in pairs correspond to the same risk level. And corresponding quantity intervals and early warning programs corresponding to the quantity intervals can be set for each risk level respectively. Therefore, when the early warning is carried out based on the second early warning program, the risk grade of the associated event type can be determined firstly, the information quantity of the warning information with the vehicle identification in the historical warning information is calculated, the target quantity interval corresponding to the risk grade is inquired based on the information quantity, and the early warning message is sent to the vehicle corresponding to the vehicle identification based on the early warning program corresponding to the target quantity interval.
Because some dangerous events have relevance, and the continuous occurrence of the relevant dangerous events generally brings great harm to the safety of vehicle driving, in the embodiment of the invention, a mapping relation is preset based on the event type of the dangerous events, and whether the dangerous events corresponding to the current alarm information are independent events or the dangerous events having the relevance continuously occur can be judged based on the mapping relation, so that the early warning can be performed based on the corresponding early warning program, and the accuracy of the early warning is improved.
In order to facilitate determination of continuous occurrence of dangerous events of associated event types and early warning as soon as possible, in the embodiment of the present invention, an associated event type having a large influence on the safety of vehicle driving may be screened from event types having an association relationship, and the associated two event types are respectively stored in different type sets, and the event types included in the two type sets are different from each other. Therefore, whether the event types have relevance can be determined directly based on whether the sets to which the event types belong are the same, and the efficiency of data processing is improved.
The following describes a method for determining whether there is a mapping relationship in step S103 in the embodiment of the present invention with reference to the system architecture shown in fig. 1. As shown in fig. 2, the method includes:
s201: and judging whether the event type of the historical alarm information and the event type of the current alarm information belong to the same type set.
In the embodiment of the present invention, the type set is preset, and may include two or more type sets, where event types in each type set do not have relevance, and the event types with relevance belong to different type sets. Therefore, when the step is executed, whether the event type of the historical alarm information and the event type of the current alarm information belong to the same type set or not can be judged, and if the event type of the historical alarm information and the event type of the current alarm information belong to the same type set, the event type of the historical alarm information and the event type of the current alarm information can be directly determined to have no relevance; if the two types do not belong to the same type set, further judgment on whether the two types have relevance may be needed.
It should be noted that, in the embodiment of the present invention, the event types may specifically include eye closing, call making, smoking, yawning, occlusion deviation, distraction, pedestrian warning, lane deviation warning, vehicle distance too close warning, front vehicle collision warning, and the like. The vehicle driver can be used for carrying out accident types of dangerous events, such as eye closing, telephone calling, smoking, yawning, shielding deviation and attention dispersion, and the accident types of dangerous events, such as pedestrian early warning, lane deviation early warning, vehicle distance over-approach early warning and front vehicle collision early warning, which are usually ADAS prompts.
As known from the specific content of the event corresponding to each event type, when a driver has a dangerous event, the driver usually causes ADAS to prompt the driver of the dangerous event, therefore, the embodiment of the invention can divide the eye closing, the telephone calling, the smoking, the yawning, the occlusion deviation and the attention distraction into a type set, namely a Driver dangerous event type set, or a Driver Status Monitor (DMS) dangerous event type set, and divides pedestrian early warning, lane deviation early warning, vehicle distance over-approach early warning and front vehicle collision early warning into a type set, namely the ADAS dangerous event type set, and establishing a directed incidence relation between the two sets, namely, two associated event types, for the event type in the driver risk event type set to point to the event type in the ADAS risk event type set, that is, setting the continuous occurrence of the risk event of the associated event type means: the type of the dangerous event which occurs first in the dangerous events which occur continuously belongs to the driver dangerous event type set, and the type of the dangerous event which occurs later belongs to the ADAS dangerous event type set. Therefore, in the embodiment of the invention, if the event type in the current alarm information belongs to the set of the dangerous event types of the driver, the situation that the dangerous events of the associated event types continuously occur is not shown; if the event type in the current alarm information belongs to the set of the driver dangerous event types, the situation that the alarm information with the event type belonging to the set of the driver dangerous event types possibly exists in the historical alarm information, namely the situation that dangerous events of the associated event types are possibly generated continuously is explained. Fig. 3 is a schematic diagram illustrating a preset association relationship between event types according to an embodiment of the present invention.
Therefore, when the step is executed, the type set to which the event type of the current alarm information belongs can be judged firstly, and if the event type of the current alarm information belongs to the driver dangerous event type set, the early warning message can be directly sent to the vehicle corresponding to the vehicle identifier based on the first early warning program; if the event type of the current alarm information belongs to the set of ADAS dangerous event types, it is further required to determine whether the event type of the historical alarm information and the event type of the current alarm information belong to the same set of types.
S202: if so, determining that the event type of the historical alarm information and the event type of the current alarm information do not have a mapping relation.
If the event type of the historical alarm information and the event type of the current alarm information belong to the same type set, and the event type of the historical alarm information and the event type of the current alarm information do not have correlation, it can be determined that the event type of the historical alarm information and the event type of the current alarm information do not have a mapping relation.
S203: if not, judging whether the event type of the historical alarm information and the event type of the current alarm information have a mapping relation based on a preset mapping relation table.
If not, it is determined that the event type of the historical alarm information and the event type of the current alarm information do not belong to the same type set, and the event types may have relevance, whether the event type of the historical alarm information and the event type of the current alarm information have a mapping relationship needs to be determined based on a preset mapping relationship table, that is, whether the event type of the historical alarm information and the event type of the current alarm information have a mapping relationship is determined by querying the mapping relationship table.
According to the embodiment of the invention, the associated event types with large influence on the driving safety of the vehicle can be screened from the event types with the association relation, the two associated event types are respectively stored into different type sets, and the event types included in the two type sets are different from each other. Therefore, whether the event types have relevance can be determined directly based on whether the sets to which the event types belong are the same, and the efficiency of data processing is improved.
