Detailed Description
Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings, in which various details of the embodiments of the present invention are included to facilitate understanding, and are to be considered 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 is noted that embodiments of the invention 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 dangerous events occur to running vehicles.
Specifically, the vehicle-mounted device for data acquisition can be installed in the vehicle, and in the running process of the vehicle, the vehicle-mounted device can acquire the data in the running process of the vehicle and send the acquired data to the database of the server. The server can call a preset alarm information generation model based on the data of the vehicles in the database, can determine the vehicles with dangerous events and generate corresponding alarm information, and then transmits the generated alarm information to the early warning system. The alarm information may include a vehicle identification, an event type, and an alarm time. The vehicle identifier is the identifier of the vehicle corresponding to the alarm information, the event type represents the type of dangerous event of the vehicle, the alarm time represents the time of sending the data of the vehicle to the database, and the time is equivalent to the time of dangerous event of the vehicle.
In the embodiment of the invention, the vehicle identifier can be a license plate number of the vehicle, and the alarm information can also comprise parameters such as enterprise information of the vehicle, for example, the highest hierarchy of the enterprise of the vehicle. The vehicle is usually driven according to the operation of a driver and an ADAS (Advanced Driving Assistance System ), so the event types may include, in particular, eye closure, telephone call, smoking, yawing, shielding deviation, distraction, pedestrian warning, lane deviation warning, approaching vehicle distance warning, front vehicle collision warning, and the like.
Based on analysis of the occurrence conditions of the vehicle accidents and the vehicle dangerous events, it can be determined that some types of dangerous events have relevance, if the dangerous events corresponding to the relevant event types occur successively for the same vehicle, namely an accident chain is formed, the possibility of the occurrence of the vehicle accidents is higher. For example, when the vehicle is running, the possibility of accident of the vehicle when the driver closes eyes and the vehicle deviates from the succession is increased, so that the association exists between the closing eyes and the early warning of the vehicle deviation, the two can form an accident chain, and the mapping relation between the two 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 of the server.
The embodiment of the invention provides a vehicle running early warning method, which can be executed by an early warning system, as shown in fig. 1, and comprises the following steps:
S101: and receiving the current alarm information, and acquiring a vehicle identifier, an event type and alarm time included in the current alarm information.
The current alarm information represents alarm information currently received by the early warning system and is alarm information of dangerous events in running of the vehicle. In the step, the vehicle identification, event type and alarm time included in the current alarm information are acquired so as to carry out subsequent analysis and early warning.
S102: and positioning the historical alarm information in the corresponding time period based on the alarm time, and judging whether the historical alarm information with the vehicle identification is included or not.
Because the occurrence of the dangerous event corresponding to the associated event type continuously increases the probability of occurrence of an accident during the running of the vehicle, in the embodiment of the invention, whether the occurrence of the dangerous event of the associated event type continuously occurs or not needs to be analyzed based on the historical alarm information and the current alarm information, and in all the steps, the historical alarm information in the corresponding time period is positioned based on the alarm time, namely, the historical alarm information of which the alarm time is in the corresponding time period of the current alarm information is positioned.
Because the related event types correspond to the dangerous events which continuously occur, the occurrence time of the two dangerous events is relatively close, the corresponding time period is determined based on the alarm time of the current alarm information in the step, and then the historical alarm information with the alarm time in the time period is positioned and analyzed to judge whether the dangerous events of the related event types continuously occur or not.
The manner of determining the corresponding time period based on the alarm time may be determined based on the alarm time, and specifically, a preset time period before and/or after the alarm time may be configured to be determined as the time period corresponding to the alarm time. Wherein the value of the preset time period can be set according to the requirement, such as 5 minutes. For example, the preset time period is set to be 5 minutes, and the alarm time of the current alarm information is set to be 1 month and 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: period of time between 59, 1 month and 1 day 23:59 to 1 month and 2 days 00: time period between 04, or 1 month and 1 day 23:56 to 1 month 2 day 00: a time period between 01, etc.
Thus, the required historical alarm information can be positioned based on the time period corresponding to the alarm time, namely, the historical alarm information of which the event type is possibly related to the event type of the current alarm information. 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 positioned, whether the historical alarm information with the vehicle identification is included or not can be judged, namely whether the positioned historical alarm information contains the alarm information with the vehicle identification in the current alarm information or not is judged, so that whether the dangerous event of the related event type continuously occurs in the same vehicle or not is judged.
It should be noted that, the history alarm information includes the vehicle identifier included in the current alarm information, and the history alarm information and the current alarm information are specific to the same vehicle.
S103: if not, based on the first early warning program, sending an early warning message to the corresponding vehicle of the vehicle identifier; if so, acquiring the event type of the historical alarm information with the vehicle identifier, 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 identifier based on the second early warning program, and if not, sending the early warning message to the vehicle corresponding to the vehicle identifier based on the first early warning program.
If no, 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 appears in the time period corresponding to the alarm time of the current alarm information, that is, the situation that the dangerous event of the related event type continuously occurs does not appear, so that it can be determined that the dangerous event corresponding to the current alarm information is an independent event, and then an early warning message can be sent to the vehicle corresponding to the vehicle identifier based on the first early warning program. If so, indicating that the located historical information has alarm information comprising the vehicle identifier in the current alarm information, namely, indicating that the alarm information of the vehicle corresponding to the current alarm information exists in the time period corresponding to the alarm time of the current alarm information, namely, indicating that the scene that the dangerous event of the related event type possibly occurs continuously for the vehicle corresponding to the current alarm information, so that the event type of the historical alarm information with the vehicle identifier can be obtained in the step to judge whether the event type of the historical alarm information and the event type of the current alarm information have a mapping relation or not, and further judging whether the dangerous event of the related event type continuously occurs for the vehicle corresponding to the current alarm information or not.
It should be noted that, since there may be a plurality of history alarm information having the vehicle identifier in the current alarm information in the located history alarm information, at this time, the history alarm information having 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 acquiring the event type of the history warning information with the vehicle identification in this step may be specifically performed as: the alarm time of each historical alarm information with the vehicle identification is acquired to determine the target alarm information closest to the alarm time of the current alarm information, and then the event type of the target alarm information is acquired.
In the process of judging whether the event type of the historical alarm information and the event type of the current alarm information have a mapping relation or not, if so, the event type of the historical alarm information is related to the event type of the current alarm information, namely, for a vehicle corresponding to the current alarm information, dangerous events of the related event type continuously occur, the probability of occurrence of accidents during vehicle driving is improved, and therefore, early warning information can be sent to a vehicle corresponding to a vehicle identifier based on a second early warning program; if not, the event type of the historical alarm information and the event type of the current alarm information are not associated, namely, for the vehicle corresponding to the current alarm information, the dangerous event of the associated event type does not continuously occur, at the moment, the dangerous event corresponding to the current alarm information can be used 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, both the second warning program and the first warning program are preset, and because the probability of an accident occurring when a dangerous event of an associated event type continuously occurs is increased, the warning level of the second warning program is generally higher than that of the first warning program, for example, the second warning program may be set to contact the driver to perform warning through a phone, and the first warning program may be set to send information to the driver to perform warning.
For the first early warning program, in the embodiment of the invention, risk levels can be further classified based on event types, for example, calling, smoking and shielding offset are set as high risk level events, yawning and distraction are carried out as medium risk level events, eye closure, pedestrian lane offset early warning and vehicle distance approaching are carried out as low risk level events, and corresponding early warning programs are set for each risk level. Therefore, when the early warning is performed based on the first early warning program, the risk level corresponding to the event type of the current alarm information can be judged first, and then the early warning is performed by the early warning program corresponding to the risk level, and the method can be specifically implemented as follows: and determining a target risk level corresponding to the event type of the current alarm information based on a corresponding relation between the preset event type and the risk level, and sending an early warning message to a vehicle corresponding to the vehicle identifier based on an early warning program of 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 warning information with the vehicle identification in the current warning information or the occurrence frequency of the warning information in the positioning history warning information. For example, two frequency thresholds may be set in embodiments of the present invention(/>Less than->) To divide three frequency intervals, which are more than or equal to 0 and less than +.>Greater than or equal to->And is less than->Greater than or equal to%>And setting corresponding early warning programs for each frequency interval, so that after early warning based on the associated event program is determined, the occurrence frequency of the warning information with the vehicle identification included in the current warning information in the historical warning information can be further calculated and positioned, and the corresponding early warning programs are determined to perform early warning by combining the frequency threshold. The frequency threshold can be determined based on the occurrence frequency of the historical alarm information, and is not smaller than epsilon and epsilon>Wherein K is a Represents the average number of alarm information received per hour in a preset time period, D c Representing the total number of the running vehicles in the preset time period, if the total number of the running vehicles in the preset time period is changed, the average value of the running vehicles can be calculated by taking the maximum value and the minimum value of the total number of the running vehicles in the preset time period, so that the total number of the running vehicles can be determined.
For another example, in the embodiment of the present invention, two number thresholds may be set to divide each number interval, and corresponding pre-warning programs are set for each number interval, so after determining that pre-warning based on the associated event program, the number of warning information with the vehicle identifier in the current warning information in the history warning information may be further calculated and located, and then the corresponding pre-warning program is determined to perform pre-warning in combination with the number interval, which may be specifically performed as follows: and calculating the information quantity of the alarm information with the vehicle identification in the historical alarm information, determining a target quantity section to which the information quantity belongs based on a preset quantity section, and sending an early warning message to the vehicle corresponding to the vehicle identification based on an early warning program corresponding to the target quantity section.
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, an associated event type formed by combining four event types of smoking, calling, collision with a preceding vehicle, and lane shifting in pairs corresponds to the same risk level, and associated event types formed by combining the other event types in pairs corresponds to the same risk level. And corresponding number intervals and pre-warning programs corresponding to the number intervals can be set for each risk level. When the early warning is carried out based on the second early warning program, the risk level of the related event type can be determined, the information quantity of the warning information with the vehicle identification in the historical warning information is calculated, and then the target quantity interval corresponding to the risk level is queried based on the information quantity, so that 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 of the relevance among some dangerous events, the continuous occurrence of the relevant dangerous events usually brings great harm to the safety of the vehicle running, so in the embodiment of the invention, the mapping relation is preset based on the event type of the dangerous events, and whether the dangerous event corresponding to the current alarm information is an independent event or the dangerous event with the relevance continuously occurs can be judged based on the mapping relation, so that the early warning can be carried out based on the corresponding early warning program, and the early warning accuracy is improved.
In order to determine the situation that dangerous events of the associated event types continuously occur so as to early warn as soon as possible, the embodiment of the invention can screen the associated event types with great influence on the safety of vehicle running from the event types with the association relationship, store the two associated event types into different type sets respectively, and enable the event types included in the two type sets to be different from each other. Therefore, whether the event types have relevance or not can be determined directly based on whether the event type belongs to the same set or not, and the efficiency of data processing is improved.
The method for determining whether there is a mapping relationship in step S103 in the embodiment of the present invention is specifically described below with reference to the system architecture shown in fig. 1. As shown in fig. 2, the method includes:
S201: 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 invention, the type sets are preset and can comprise two or more type sets, the event types in each type set have no 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 first, 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 current alarm information and the event type of the current alarm information do not have relevance can be directly determined; if both do not belong to the same set of types, it may be further necessary to determine if both have an association.
In the embodiment of the invention, the event types may include eye closure, phone call, smoking, yawning, shielding deviation, distraction, pedestrian early warning, lane deviation early warning, approaching vehicle distance early warning, front vehicle collision early warning, and the like. Wherein, the closing of eyes, making telephone calls, smoking, making yawns, shielding deviation and distraction are event types that are usually dangerous events that a vehicle driver can take, pedestrian pre-warning, lane departure pre-warning, vehicle distance approaching pre-warning, front vehicle collision pre-warning and the like are event types which are usually ADAS (advanced automatic analysis system) prompting dangerous events.
The specific content of the event corresponding to each event type can know that the occurrence of the dangerous event by the driver usually causes the ADAS to prompt the occurrence of the dangerous event, so that in the embodiment of the invention, the eye closure, the call making, the smoking, the yawning, the shielding deviation and the attention scattering can be divided into one type set, namely, the driver dangerous event type set, or the DMS (Driver Status Monitor, driver state monitoring) dangerous event type set, the pedestrian early warning, the lane deviation early warning, the vehicle distance approaching early warning and the front vehicle collision early warning are divided into one type set, namely, the ADAS dangerous event type set, and a directed association relation is established between the two sets, namely, the two associated event types are that the event types in the driver dangerous event type set point to the event types in the ADAS dangerous event type set, namely, the dangerous event with the associated event types is set, namely, the continuous occurrence of the dangerous event is indicated as the associated event type: the event types of the dangerous events which occur first in the continuously occurring dangerous events belong to a driver dangerous event type set, and the event types of the dangerous events which occur later belong to an ADAS dangerous event type set. Therefore, in the embodiment of the invention, if the event type in the current alarm information belongs to the driver dangerous event type set, the situation that the dangerous event of the related event type continuously occurs is indicated; if the event type in the current alarm information is the set of dangerous event types belonging to the driver, the alarm information that the event type belongs to the set of dangerous event types of the driver possibly exists in the historical alarm information is indicated, that is, the situation that the dangerous events of the related event types continuously occur possibly occurs. Fig. 3 is a schematic diagram illustrating a preset association relationship between event types in an embodiment of the present invention.
Therefore, when the step is executed, which type set the event type of the current alarm information belongs to can be judged first, and if the event type of the current alarm information belongs to the driver dangerous event type set, an early warning message can be sent to a vehicle corresponding to the vehicle identifier directly based on the first early warning program; if the event type of the current alarm information belongs to the ADAS dangerous event type set, 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 or not.
S202: if yes, 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 have no relevance, the event type of the historical alarm information and the event type of the current alarm information can be determined to have no mapping relation.
S203: if not, based on a preset mapping relation table, judging whether the event type of the historical alarm information and the event type of the current alarm information have a mapping relation or not.
If not, the event type of the historical alarm information and the event type of the current alarm information are not the same type set, and the event type of the historical alarm information and the event type of the current alarm information are possibly associated, and whether the event type of the historical alarm information and the event type of the current alarm information have a mapping relation or not is judged based on a preset mapping relation table, namely whether the event type of the historical alarm information and the event type of the current alarm information have the mapping relation or not is determined by inquiring the mapping relation table.
In the embodiment of the invention, the associated event types with great influence on the safety of the vehicle running can be screened out from the event types with the association relationship, the two associated event types are respectively stored into different type sets, and the event types included in the two type sets are mutually different. Therefore, whether the event types have relevance or not can be determined directly based on whether the event type belongs to the same set or not, and the efficiency of data processing is improved.
