Description
Technical Field
The application belongs to the field of research on safe driving of automobiles, and particularly relates to a method, a device, electronic equipment and a system for monitoring speed limit of an automobile.
Background
In an actual traffic operation scene, accidents often occur along with high vehicle speed. Therefore, in traffic management, limiting the speed of a driver on some road sections becomes a necessary means for improving traffic safety. In reality, the method for limiting the speed of the driver is to arrange a speed limit sign beside the road and arrange a vibration band on the road, and a common speed limit means is to apply a speed reduction marking line on a specific road section. The marking line utilizes the visual illusion phenomenon generated when a driver sees the marking line in the high-speed driving process, so that the driver subjectively thinks that the speed of the driver is higher and higher or the lane where the driver is located is narrower and narrower, the driver is forced to actively reduce the speed of the driver, and the purpose of safe driving is achieved. However, in practice, these deceleration markings often do not achieve the desired deceleration effect when the driver is familiar with the route being traveled.
The current technology for monitoring vehicle deceleration is mainly realized by devices on a vehicle, and the method limits the vehicle speed by detecting the operation of a driver or an accelerator pedal sensor and the like. Such methods only concern the state of the vehicle or the driver himself, and do not concern differences in driving environment. When the driving environment is different, the result obtained by the monitoring technology becomes absolute and unreliable, and the problems that the applicable scene of the method is single and the use is not flexible are reflected behind the result.

s201, acquiring the current running speed of the vehicle.
According to the embodiment of the application, the current running speed of the vehicle is collected through the speed collector, the running speed of the vehicle is collected by the speed collector and then transmitted to the electronic equipment, and the electronic equipment can obtain the current running speed of the vehicle.
And S202, detecting the speed limit information of the road section.
In an embodiment of the application, after the electronic device obtains the driving speed of the vehicle, the electronic device needs to detect the speed limit information of the road section.
As an implementation manner for detecting the speed limit information of the road section, in the embodiment of the application, environmental data is collected through a sensor, for example, when a vehicle runs on a section of road, images are continuously shot through a camera, the shot images include an image of the speed limit board of the road section and an image not including the speed limit board of the road section, the camera can identify the image including the speed limit board of the road section, the image including the speed limit board of the road section is transmitted to an electronic device through the camera, the electronic device can receive the image including the speed limit board of the road section shot by the camera, further, the speed limit information of the road section in the image of the speed limit board of the road section can be extracted, and then the speed limit information of the road section is detected. If the vehicle runs through the road section, the image shot by the camera only contains the image without the road section speed limit information, the image is not required to be transmitted to the electronic equipment, and the electronic equipment does not detect the road section speed limit information.
As another implementation manner for detecting the speed limit information of the road section, in the embodiment of the application, environmental data is collected by a sensor, for example, when a vehicle runs on a section of road, images are continuously shot by a camera, the shot images include an image of the speed limit board of the road section and an image without the speed limit board of the road section, the camera transmits all the shot images including the image of the speed limit board of the road section and the image without the speed limit board of the road section to an electronic device, the electronic device identifies the image transmitted by the camera, and if the image including the speed limit board of the road section is identified, the speed limit information of the road section in the image of the speed limit board of the road section is extracted, and the speed limit information of the road section is detected. If the vehicle runs through the road section, the electronic equipment cannot recognize the image containing the road section speed limit board, and the road section speed limit information is not detected.
As another implementation way for detecting speed limit information of a road section, in the embodiment of the application, various radar probes on a road can be detected through a vehicle-mounted navigation system or a vehicle-mounted electronic dog, so that the speed limit information of the road section can be directly detected. If the electronic equipment can receive the road section speed limit information transmitted by the vehicle-mounted navigation system or the vehicle-mounted electronic dog, the road section speed limit information is detected, and if the electronic equipment cannot receive the road section speed limit information transmitted by the vehicle-mounted navigation system or the vehicle-mounted electronic dog, the road section speed limit information is not detected.
When the road section speed limit information is detected, the priority of the mode of collecting the environmental data by using the sensor and further detecting the road section speed limit information is higher than that of the mode of directly detecting the road section speed limit information by using the vehicle-mounted navigation system or the vehicle-mounted electronic dog and further detecting the road section speed limit information. That is, when detecting the speed limit information of the road section, the detection may be performed by using a sensor to collect the environmental data, or may be performed by using a car navigation system or a car dongle, and the detection result of the detection by using a sensor to collect the environmental data is preferentially used.
S203, when the speed limit information of the road section is detected, if the driving speed is determined to be greater than the preset first speed and less than or equal to the speed limit value corresponding to the speed limit information of the road section, the speed reduction marking line is identified.
In an embodiment of the application, after the electronic device detects the road section speed limit information, the speed limit value corresponding to the road section speed limit information is extracted, and the acquired vehicle running speed is compared with the road section speed limit value in the detected road section speed limit information.
When the electronic equipment determines that the driving speed is greater than the preset first speed and less than or equal to the speed limit information of the road section, the electronic equipment also needs to identify the speed reduction marking line to judge whether the vehicle needs to be decelerated.
It should be noted that the preset first speed is a speed at which the vehicle runs safely, and the preset first speed in the embodiment of the present application may be set to 25 to 35km/h, preferably 30km/h, that is, when the speed of the vehicle is maintained at 30km/h or less, the vehicle can run safely without being decelerated regardless of whether the vehicle runs at a railroad crossing, a sharp turn, a narrow road, a narrow bridge, or runs at a rush hour, commute, school, etc.
And S204, when the deceleration marked line is identified, controlling the vehicle to decelerate.
According to the embodiment of the application, when the driving speed is greater than the preset first speed and less than or equal to the speed limit information of the road section, the speed reduction marked line needs to be identified.
As an implementation manner of recognizing the speed reduction marking, the embodiment of the application collects the environmental data through the sensor, specifically, when the vehicle runs on a section of road, the camera continuously shoots images, the shot images include the image of the speed reduction marking and the image without the speed reduction marking, the camera can recognize the image including the speed reduction marking, the camera transmits the image including the speed reduction marking to the electronic device, and the electronic device can receive the image including the road speed limit plate shot by the camera, so that the speed reduction marking can be recognized. If the vehicle runs on the road section, the image shot by the camera only contains the image without the speed reduction marking, the image is not required to be transmitted to the electronic equipment, and the electronic equipment does not recognize the speed reduction marking.
As another implementation manner of identifying the deceleration marked line, in the embodiment of the application, the sensor is used for acquiring the environment data, specifically, when the vehicle runs on a section of road, the camera is used for shooting an image, the shot image comprises an image of the deceleration marked line and an image without the deceleration marked line, the camera transmits all the shot images comprising the deceleration marked line and the image without the deceleration marked line to the electronic device, the electronic device identifies the image transmitted by the camera, and if the image comprising the deceleration marked line is identified, the deceleration marked line is identified. If the vehicle runs through the road section, the electronic equipment cannot recognize the image containing the speed reduction marked line, and the speed reduction marked line is not recognized.
When the electronic equipment identifies the deceleration marked line, the vehicle is controlled to decelerate. Illustratively, when the electronic equipment identifies the speed reduction marked line, the electronic equipment controls the alarm to send out a speed reduction alarm signal, controls the vehicle to decelerate at a speed reduction ratio of 20%, and decelerates the vehicle speed to a preset first speed.
And S205, if the deceleration marked line is not identified, controlling the vehicle to continuously run at the current running speed.
On the premise that the driving speed is greater than the preset first speed and less than or equal to the speed limit information of the road section, if the electronic equipment does not recognize the speed reduction marking line, it is proved that the vehicle does not need to be decelerated when driving on the road section, and the electronic equipment controls the vehicle to continuously drive at the current driving speed.
And S206, when the road section speed limit information is detected, if the running speed is determined to be less than or equal to the preset first speed, controlling the vehicle to continue running at the current running speed.
In the embodiment of the application, on the premise that the electronic device detects the speed limit information of the road section, the electronic device compares the running speed with the preset first speed, and if the running speed is determined to be less than or equal to the preset first speed, it is proved that the vehicle does not need to be decelerated when running on the road section, and the electronic device controls the vehicle to continue running at the current running speed. The specific meaning of the preset first speed is already described in S203, and is not described herein.
And S207, when the road section speed limit information is detected, if the running speed is determined to be greater than the road section speed limit information, controlling the vehicle to decelerate.
In the embodiment of the application, on the premise that the electronic device detects the speed limit information of the road section, the electronic device compares the driving speed with the speed limit value corresponding to the speed limit information of the road section, if the electronic device determines that the driving speed is greater than the speed limit information of the road section, it is proved that the speed of the vehicle needs to be reduced when the vehicle drives on the road section, and the electronic device controls the alarm to send out speed reduction alarm information and controls the vehicle to reduce the speed to be below the speed limit value corresponding to the speed limit information of the road section.
And S208, when the speed limit information of the road section is not detected, identifying the speed reduction marked line.

In the embodiment of the application, on the premise that the electronic device identifies the speed reduction marking line, the running speed is compared with the preset second speed, if the running speed is greater than the preset second speed, it is proved that the vehicle needs to be decelerated when running on the road section, and the electronic device controls the vehicle to decelerate to be below the preset second speed.
It should be noted that the preset second speed is preset in the electronic device, and the preset second speed may be determined according to the speed limit values of different regions and different road sections. The determination may be made according to the forty-fifth regulation of the regulations on the implementation of the traffic safety laws of the people's republic of China, and the forty-fifth regulation of the regulations on the implementation of the traffic safety laws of the people's republic of China: the motor vehicle can not exceed the speed indicated by the speed limit sign and the marking line when running on the road, and can not exceed the following highest running speed when running on the road without the speed limit sign and the marking line:
