Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Fig. 1 is a schematic view of an application environment of an embodiment of a secondary accident warning method according to the present invention. As shown in fig. 1, road monitoring devices are respectively arranged on two sides of a road guardrail of a motor vehicle lane, and each road monitoring device comprises a monitoring module and a positioning module, wherein the monitoring modules are used for monitoring vehicle information on corresponding road sections. The positioning module is used for positioning the position of the road monitoring device. The monitoring range of the monitoring module is related to the type of monitoring module used. The invention does not limit the types of the monitoring module and the positioning module, for example, the monitoring mode of the monitoring module can be radar monitoring, ultrasonic monitoring and the like, and the positioning mode of the positioning module can be GPRS positioning. And judging whether the road section has an accident or not according to the vehicle information. The road monitoring device is provided with a camera and can acquire videos of corresponding road sections.
When an accident occurs, in order to avoid the occurrence of a secondary accident, the road monitoring device sends an accident alarm signal and acquires images of corresponding road sections so as to analyze the lane where the accident vehicle is located and accident handling information. The road monitoring device comprises a communication module, and can be connected with a road management platform and a third-party map through a wide area communication network so as to broadcast accident information of a corresponding road section. The communication module can also be used for short-range direct communication between road monitoring devices.
When no accident occurs, the accident information broadcast by other road monitoring devices on the same side of the front of the road section is received, and a deceleration warning signal is sent out according to the distance between the accident information and the other road monitoring devices broadcasting the accident information, so that secondary accident early warning is realized.
Fig. 2 is a flowchart of a first embodiment of a secondary accident warning method according to the present invention. As shown in fig. 2, the method comprises the steps of:
step S101: and acquiring the vehicle information on the corresponding road section monitored by the road monitoring device.
In this step, the vehicle information refers to the vehicle travel information on the corresponding link, and includes the position of the vehicle on the link, the vehicle speed, and the like. Vehicle information monitored by a monitoring module of the road monitoring device is processed and analyzed by a processor of the road monitoring device.
Step S102: and judging whether the accident happens to the road section according to the vehicle information, if so, executing step S103, and if not, executing step S104.
In this step, the vehicle information includes the speed of the vehicle, and it is possible to determine whether an accident has occurred in the road section according to the speed of the vehicle.
Step S103: an accident warning signal is issued and accident information is broadcast.
In this step, the presenting mode of the accident warning signal may be a voice warning or an optical signal warning, which is not limited in the present invention.
Step S104: and judging whether accident information broadcasted by other road monitoring devices on the same side in front of the road section is received, if so, executing the step S105, and if not, determining that no accident occurs.
For a specific determination manner in this step, please refer to the specific description in fig. 4, which is not described herein again.
Step S105: the distance between the road segment and other road monitoring devices broadcasting the accident information is calculated.
The distance between the road section and the road monitoring device broadcasting the accident information is determined by the distance between the road monitoring device monitoring the road section and the road monitoring device broadcasting the accident information. The distance may be calculated from the position of the marker on the electronic map.
Step S106: and when the distance is smaller than a preset first preset distance, determining whether the vehicle on the road section is in a normal driving state or not according to the vehicle information on the corresponding road section monitored by the road monitoring device, if so, executing a step S107, and if not, determining that a deceleration warning signal does not need to be sent out.
In this step, the normal driving state refers to a formal state in which the speed is greater than a prescribed minimum speed value for the link. In this embodiment, determining whether the vehicle on the road segment is in the normal driving state further comprises: and judging whether the speed of the vehicle is greater than a preset first threshold value or not, and if so, determining that the vehicle on the road section is in a normal driving state. The preset first threshold value refers to a specified lowest speed value of the road section. For example, the lowest speed of the section is 30Km/h, and when the vehicle speed is greater than 30Km/h, it is determined that the vehicle is in a normal driving state.
Step S107: and sending a deceleration warning signal.
When the distance between the road section and the nearest road monitoring device is smaller than the first preset distance, a vehicle entering the road section may cause a secondary accident, and a deceleration warning signal needs to be sent out. Specifically, when the distance is smaller than a preset first preset distance and is greater than or equal to a second preset distance, the deceleration warning signal is presented in a first expression form, wherein the second preset distance is smaller than the first preset distance; and when the distance is smaller than the second preset distance, enabling the deceleration warning signal to be presented in a second expression form, wherein the first expression form is different from the second expression form.
When the distance between the road section and the nearest road monitoring device is smaller than a second preset distance, secondary accidents inevitably occur, in order to distinguish the severity of the deceleration alarm, when the distance is between the second preset distance and the first preset distance, the alarm signal is presented in a first presentation form, and when the distance is smaller than the second preset distance, the alarm signal is presented in a second presentation form. For example, the first expression is an intermittent acousto-optic alarm and the second expression is a persistent acousto-optic alarm. The present invention is not limited to the specific presentation forms of the first expression form and the second expression form.
The embodiment of the invention monitors the vehicle information on the corresponding road section through the road monitoring device, judges whether the road section has an accident according to the vehicle information, sends out an accident alarm signal when the accident occurs, and judges whether the deceleration alarm signal needs to be sent out by judging whether the accident information broadcasted by other road monitoring devices on the same side of the front of the road section is received when the accident does not occur. Therefore, the embodiment of the invention can realize the warning when the road accident occurs, thereby solving the problem that the secondary accident can not be warned.
Fig. 3 is a flowchart of a first embodiment of a method for warning a secondary accident according to the present invention, and compared with the first embodiment, the method for determining whether an accident occurs in the road segment according to the speed of the vehicle according to the embodiment of the present invention includes the following steps as shown in fig. 3:
step S301: and judging whether a vehicle with the speed of zero exists according to the vehicle information, if so, executing step S302, and if not, determining that no accident occurs in the road section.
When there is a vehicle with a speed of zero, an accident may occur, or a congestion may occur, it is further determined whether the accident occurs on the road section through the following steps. When no vehicle with the speed of zero exists, the road section is considered to have no accident.
Step S302: generating a speed report broadcasts the speed report.
The road monitoring devices can communicate with each other through short-distance direct connection. The speed report is used to inform other road monitoring devices that there is a vehicle with zero speed on the road segment. In a specific implementation, the speed report may be broadcast in the form of a data packet, for example, a speed bit is set in the data packet, and when there is a vehicle with a zero speed, the speed bit is set to 1, and when there is no vehicle with a zero speed, the speed bit is set to 0. The present invention is not limited in the form of speed reports.
Step S303: the speed report is broadcast.
Step S304: and judging whether a speed report broadcasted by other road monitoring devices on the same side of the road section is received, if not, executing the step S305, and if so, executing the step S306.
The speed report carries the location identification and direction identification of the road monitoring device broadcasting the speed report. In this step, if a speed report broadcast by other road monitoring devices on the same side of the road section ahead is received, it is determined that the road section is only congested and no accident occurs, and if the speed report is not received, it is determined that the accident occurs on the road section. The step of judging whether the speed report broadcasted by other road monitoring devices on the same side in front of the road section is received or not comprises the following steps as shown in fig. 4:
step S401: when a speed report is received, a direction identification is extracted from the speed report.
The direction identification is used for identifying the position of the road monitoring device on the guardrail, and the direction identifications of the road monitoring devices positioned on the same side of the guardrail are the same. In a specific implementation process, the direction identifier may be identified by a direction identifier flag bit, for example, the flag bit of the direction identifier of the road monitoring device located on one side of the guardrail is set to 1, and the flag bit of the direction identifier of the road monitoring device located on the other side of the guardrail is set to 0. When broadcasting the speed report, the speed report is sent in a set format, for example, in a data packet form, and the data packet includes a flag bit of a direction identifier, so that the road monitoring device receiving the speed report can conveniently judge whether the road monitoring device broadcasting the speed report is positioned on the same side of the guardrail as the road monitoring device according to the flag bit of the direction identifier.
Step S402: and judging whether the extracted direction identifier is the same as the direction identifier of the road monitoring device, if so, executing a step S1043, and if not, determining that the speed report broadcasted by other road monitoring devices on the same side of the front of the road section is not received.
After the road monitoring device extracts the direction identification, the direction identification is compared with the direction identification of the road monitoring device to determine whether the direction identification is consistent with the direction identification of the road monitoring device.
Step S403: it is determined that the road monitoring device broadcasting the speed report is on the same side of the road as itself.
If the extracted direction identification is the same as the direction identification of the road monitoring device itself, then it is determined that the road monitoring device broadcasting the speed report is on the same side of the road as itself.
Step S404: the vehicle direction of travel for the road segment is determined.
The road monitoring devices can communicate with each other through short-distance direct connection. In this step, the driving direction of the road section can be determined according to the sequence of the information of the same vehicle monitored by the adjacent road monitoring devices.
In some embodiments, when the road monitoring device is installed, the driving direction of the road segment may be previously stored in the road monitoring device according to the road segment monitored by the road monitoring device.
Step S405: an electronic map containing the road is obtained and a location identification is extracted from the speed report.
The location identifier is used to identify a specific location of the road monitoring device. The road monitoring device comprises a positioning module for positioning the position of the road monitoring device. The present invention does not specifically limit the positioning mode of the positioning module, for example, GPRS positioning. According to the position of the road monitoring device, an electronic map of the road on which the road section monitored by the road monitoring device is located can be obtained. The electronic map may be stored in the road monitoring device in advance, or may be acquired from a road management platform or a third-party map connected to the road monitoring device.
Step S406: and positioning the self position of the road monitoring device and the broadcast position corresponding to the position identification in the electronic map.
In this step, the broadcast location refers to the location of the road monitoring device broadcasting the speed report, and the location may be presented in the form of coordinates or may be presented by specific geographical location information, such as longitude and latitude. The road monitoring device positions the self position through the positioning module and positions the broadcast position according to the position identification. When the self position and the broadcast position are located in the electronic map, the position can be marked by a special point, for example, an asterisk mark is used, and the position can also be marked by a letter, and the invention is not limited by the locating mode.
Step S407: directions from the location of the road monitoring device itself to the broadcast location are constructed.
And determining the direction from the self position to the broadcast position according to the self position and the broadcast position positioned in the electronic map.
Step S408: and judging whether the direction from the self position to the broadcast position is the same as the vehicle running direction or not, if so, executing step S409, and if not, executing step S410.
Step S409: it is determined that the speed report is broadcast from other road monitoring devices ahead of the road segment.
When the direction from the self position to the broadcast position is the same as the vehicle driving direction, the speed report is determined to be broadcast from other road monitoring devices in front of the road section.
Step S410: it is determined that the speed report is broadcast from other road monitoring devices behind the road segment.
Step S305: and determining that the accident happens to the road section.
Step S306: and determining that no accident occurs on the road section.
When the road monitoring device monitors that the vehicle speed of the corresponding road section is zero, a speed report is generated and broadcasted, whether an accident happens to the current road is judged according to whether the speed report broadcasted by other road monitoring devices on the same side in the front is received, an accident early warning is sent out when the accident happens, and a deceleration early warning is sent out when the accident happens to the front road section, so that secondary accident early warning is realized, and the occurrence of secondary accidents is avoided.

As shown in fig. 5, this embodiment is different from the first embodiment in that the road monitoring device includes a camera, and when there is a vehicle with a zero speed, after generating the speed report and before broadcasting the speed report, the present embodiment further includes the following steps:
step S501: and acquiring images of corresponding road sections monitored by the road monitoring device.
In this step, the image of the corresponding road section monitored by the road monitoring device includes the position of the vehicle on the corresponding road section on the road section.
Step S502: based on the image, a lane in which a vehicle with a speed of zero is present is analyzed.
And determining the lane where the vehicle is located according to the position of the vehicle with the zero speed on the road section.
Step S503: and packaging the lane information obtained by analysis into a speed report.
In this step, the speed report may be broadcast in the form of a data packet. In the data weight protection corresponding to the speed report, a lane marker can be set to distinguish the lane where the vehicle is located.
According to the embodiment of the invention, the images on the corresponding road sections monitored by the road monitoring device are collected, the lane where the vehicle with the speed of zero is located is analyzed, and the information is packaged in the speed report, so that the road monitoring device can conveniently broadcast the lane where the accident vehicle is located to prompt other vehicles to change lanes for driving, and the traffic efficiency is improved.
