Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Road cones have an irreplaceable role in roads, and are usually placed in the middle of roads or in dangerous areas to guide traffic flows for sections such as highway maintenance, law enforcement, road construction, and the like. Traditional way awl needs the road administration personnel to carry out the manual work and puts, and the in-process of putting is very easily collided with the vehicle that traveles in the road, and danger is higher. Along with the development of the technology, intelligent road cone equipment is gradually applied to practical scenes, for example, a movable base is arranged in some intelligent road cone equipment, the movement of the road cone can be realized through wireless remote control, and road administration personnel can remotely control the road cones to a required area without manual placement. Still some intelligence way awl equipment can be realized with the form of robot, and the higher authority is provided with a plurality of way cones, and the road administration personnel reach through operation robot and put the region back and put through the arm and put. The purpose of above-mentioned intelligence way awl equipment is all to let personnel keep away from the road to the risk has been reduced.
With the rapid development of the intelligent transportation field, various related transportation devices are gradually interconnected, for example, a communication module is built in a vehicle, so that the vehicle networking function can be realized, and the vehicle networking device is interconnected with other roadside devices with networking functions. However, in the connection interaction process with the intelligent road cone device, a related interaction mode is still lacked in the prior art, so that the intelligent degree of the intelligent road cone device is low.
In view of the above problems existing in the existing intelligent road cones, an object of the present invention is to provide an interactive method of an intelligent road cone and an intelligent road cone, which are described below by way of embodiments.
To facilitate understanding of the embodiment, first, a detailed description is given to an interaction method of an intelligent road cone disclosed in the embodiment of the present invention, where a flowchart of the method is shown in fig. 1, and the method includes the following steps:
and S101, acquiring position data of the intelligent road cone.
For the intelligent road cone with the built-in positioning chip, the position data can be determined directly through the positioning chip, and the position data can be determined according to the positioning protocols supported by the positioning chip, wherein the protocols comprise: GPS (Global positioning System), QZSS (Quasi-Zenith Satellite System), GLONASS (Global NAVIGATION Satellite SATELLITE SYSTEM, GLONASS Satellite NAVIGATION System), Galileo (Galileo Satellite NAVIGATION System), and beidou Satellite System.
The position data directly acquired by the positioning chip is longitude and latitude data, and the obtained position data can be universal regardless of which type of positioning chip is adopted because the longitude and latitude data are unique and a reference system does not need to be set. For example, in a plurality of intelligent road cones in the same scene, the positioning chips built in one part of the intelligent road cones only support the Beidou satellite chip, and the positioning chips built in the other part of the intelligent road cones only support the GPS chip, but the results obtained by the two types of intelligent road cones can be universal.
For an intelligent road cone without a positioning chip, a uniform reference point needs to be determined, and the relative position data of the intelligent road cone can be obtained according to the position of the reference point. For example, an object with a fixed position and convenient measurement can be selected as a reference point according to the field environment, for example, when a road is constructed, the central point of the area of the road construction can be used as the reference point; roadside poles or trees and the like can also be arranged as reference points.
After the reference point is established, the position data of the intelligent road cone can be determined according to the distance and the direction between the intelligent road cone and the reference point. Since the position data in this case is a relative value, the reference point cannot be changed, otherwise the position data also needs to be changed.
And S102, calculating the distance between the intelligent road cone and the running vehicle in real time according to the position data of the intelligent road cone.
And calculating according to the position data of the intelligent road cone and the position data of the vehicle to obtain the distance between the vehicle and the intelligent road cone. If the intelligent road cone is internally provided with the positioning chip and the vehicle is also internally provided with the positioning chip, the distance between the intelligent road cone and the running vehicle can be obtained by calculating the position data acquired from the positioning chips of the intelligent road cone and the vehicle. The calculation process can be realized in a cloud server, the transmission process to the cloud can be carried out through a built-in related communication module in the intelligent road cone, and data transmission can be realized through the built-in related communication module in a vehicle. The protocol used by the communication module may be implemented by any one of the communication protocols mentioned above, such as DSRC (Dedicated Short Range Communications ), LTE-V (Long Term Evolution-Vehicle, Long Term Evolution traffic Communications), 4G (4th-Generation, fourth Generation Communications), 5G (5th-Generation, fifth Generation Communications), WLAN (Wireless Local Area Network), and bluetooth.
If the intelligent road cone device or the vehicle does not have the networking function and the positioning function, the distance calculation between the intelligent road cone and the vehicle can be realized by other auxiliary devices deployed in the road. For example, the vehicle can be subjected to pattern recognition through the bayonet camera, the distance between the vehicle and the bayonet camera is obtained by applying a related distance measurement algorithm, and the distance between the vehicle and the intelligent road cone can be calculated by combining the position data of the intelligent road cone. The speed of the running vehicle can be measured through the speed measuring radar, and the track of the running vehicle is predicted by combining the position of a radar speed measuring point and the speed of the running vehicle passing through the speed measuring point, so that corresponding position data is obtained.
And S103, when the distance between the intelligent road cone and the vehicle does not meet a preset threshold value, moving the intelligent road cone to enable the distance between the intelligent road cone and the vehicle to meet a preset threshold value relation.
The setting of threshold value need to combine specific use scene can confirm, for example when the accident takes place, need put intelligent way awl to required position to reach the protection scene of the accident, prevent the purpose of secondary collision. After the intelligent road cones are placed at the moment, the intelligent road cones are moved by combining the positions of surrounding vehicles so as to protect the accident site to the maximum extent. If an accident occurs in the expressway, the intelligent road cone can automatically move to about 150 meters according to the distance data between the intelligent road cone and the subsequent vehicles after being initially placed, and can be used as a warning board; if the accident happens in the urban road, the intelligent road cone moves to a proper position according to the distance of surrounding vehicles, and the influence on other vehicles is reduced as far as possible under the condition that the accident scene is not influenced.
The movement of the intelligent road cone also comprises passive movement, and the scene is often generated in the process of first placing of the intelligent road cone. When the intelligent road cone is implemented specifically, the intelligent road cone usually needs a road administration worker to substitute the road cone into a road to be placed, and the road cone is placed initially through manual work. Because the intelligent road cones are movable, usually road administration personnel intensively place the intelligent road cones in a specific area, and then the intelligent road cones move according to a preset threshold value relation. And when the distance between the intelligent road cone and the vehicle meets the preset threshold value relationship, stopping moving the roadblock, and then still keeping the real-time judgment of the distance between the intelligent road cone and the vehicle. In the process, the threshold value can be changed under the influence of actual conditions, and when the threshold value is changed, the intelligent roadblock moves along with the threshold value and moves to the position meeting the threshold value relation.
In the interaction method of the energy road cone, the intelligent road cone interacts with other road equipment through the built-in related communication module, and analysis and judgment are carried out on vehicles running in the road, so that the placement of the intelligent road cone is finally realized, the interaction mode of the intelligent road cone and an intelligent traffic network is increased, and the intelligent degree of the intelligent road cone equipment is improved.
As shown in fig. 2, in some embodiments, if neither the vehicle nor the intelligent road cone can be networked or located, the step S102 further includes:
in step S201, position data of a traveling vehicle is acquired by a road monitoring device.
The road monitoring equipment in the step can be any one of a bayonet camera, a speed measuring radar, infrared detection equipment, tail gas detection and the like. The bayonet camera can acquire the position information of the vehicle by snapshotting the running vehicle and combining the position of the bayonet camera; the speed measuring radar can measure the speed of the vehicle to obtain the speed of the vehicle, and the subsequent running of the vehicle can be predicted by combining the speed measuring radar with the bayonet camera; the infrared detection device is usually used for detecting the flow of the vehicle, and the vehicle can count when passing through the infrared detection device, so that the position information of the vehicle can be directly obtained through the deployed position of the infrared detection device; exhaust gas detection is usually provided in a particular area of a road, and when a vehicle travels to the area, an exhaust gas emission result is directly given by an exhaust gas detection device, so that the position information of the vehicle can also be obtained from the position information of the area.
And S202, calculating the distance between the intelligent road cone and the running vehicle in real time according to the position data of the intelligent road cone and the position data of the vehicle.
After the position data of the vehicle is acquired, the distance between the intelligent road cone and the running vehicle can be obtained through a corresponding calculation method by combining the position data of the intelligent road side.
For example, the position data of the intelligent road cone is acquired and determined according to a bayonet camera, a speed measuring radar, an infrared detection device, tail gas detection and the like selected by the road detection device, for example, when the road detection device selects the bayonet camera, the position of the intelligent road cone is determined according to the reference point which is the position of the bayonet camera; similarly, the speed measuring radar, the infrared detection equipment, the tail gas detection equipment and the like all use the positions of the respective equipment as reference points.
In some embodiments, the road monitoring device comprises a plurality of road bayonet cameras, as shown in fig. 3.
The distance between the intelligent road cone and the running vehicle can be calculated by the following formula:
in the above formula, d is the distance between the intelligent road cone and the running vehicle; c is the distance between the vehicle and the first road bayonet camera; s is the distance between the first road bayonet camera and the second road bayonet camera; l represents the distance between the intelligent road cone and the second road bayonet camera.
After the distance between the intelligent road cone and the running vehicle is obtained, as shown in fig. 4, the step of moving the intelligent road cone so that the distance between the intelligent road cone and the vehicle meets a preset threshold relationship includes:
in step S401, speed information of the vehicle is acquired.
The speed of the vehicle is calculated using the following equation:
in the above equation, v is a velocity value of the vehicle; t is tT-1The moment when the vehicle passes through the first road bayonet camera; t is tTThe moment when the vehicle passes through the second road bayonet camera; and S is the distance between the first road bayonet camera and the second road bayonet camera.
And S402, calculating the time of the vehicle reaching the intelligent road cone according to the speed information of the vehicle and the distance between the intelligent road cone and the vehicle.
After the acquired distance between the intelligent road cone and the vehicle and the speed of the vehicle are obtained, the time when the vehicle reaches the intelligent road cone can be roughly calculated, so that the value of the time can be referred to for setting the threshold value. The time when the vehicle reaches the intelligent road cone is rough time, and the measured vehicle cannot be guaranteed to run at a constant speed, so that the setting range of the threshold value can be set to be a wider numerical value.
And S403, controlling the road cone to move according to the time when the vehicle reaches the intelligent road cone.
As shown in fig. 5, the process of controlling the intelligent road cone to move includes:
and step S41, obtaining a preliminary placement scheme of the intelligent road cone according to the placement scene of the intelligent road cone.
For example, in a scene such as road construction, an intelligent road cone needs to be placed around a construction area, as shown in fig. 6, the length of the construction area is m meters, and for the convenience of observing running vehicles, a preliminary scheme for placing the road cones is trapezoidal placement. The sides of the trapezoids may guide the vehicle away from the work area.
And step S42, when the intelligent road cone is placed for the first time, preferentially placing the intelligent road cone in which the vehicle arrives at the placement area earlier according to the driving direction of the vehicle.
When intelligent way awl was put for the first time, at first according to the vehicle direction of travel, the intelligent way awl of putting the region is put earlier to the preferred vehicle of putting. Since the vehicle is placed for the first time, the construction area is still exposed to the running vehicle, and therefore the vehicle is placed on the side where the vehicle arrives first.
And step S43, when the intelligent road cone moves subsequently, preferentially placing the intelligent road cone of which the vehicle arrives at the placing area later according to the driving direction of the vehicle.
Along with the construction, the working condition of the road is gradually improved, and at the moment, the x area in the construction process is evaluated to judge whether the construction is finished or not. If the construction is finished, the intelligent road cones that the vehicles arrive at the placing areas later are preferentially placed according to the driving directions of the vehicles, and then the intelligent road cones that the vehicles arrive at the placing areas earlier are placed, so that the influence of the movement of the intelligent road cones on the vehicles is reduced as much as possible.
If the intelligent road cone side reaching the placement area later from the vehicle is not constructed continuously, only the road cone closer to the vehicle is moved until the construction is finished.
Neither the vehicle nor the intelligent road cone in the above embodiment can be networked or located, so before step S102, it is necessary to determine whether the vehicle and the intelligent road cone can be networked, as shown in fig. 7, including the following steps:
and step S701, judging whether the vehicles are networked.
Whether the vehicles can be networked or not depends on the configuration of the vehicles, and the method for judging whether the vehicles are networked or not can acquire vehicle networking information through the control center. The control center is deployed at the cloud end and used for collecting and planning road condition information. Because intelligence way awl also need carry out data interaction according to control center, consequently judge whether the vehicle is networked and can acquire through control center.
And step S702, connecting the intelligent road cone with the vehicle.
If the vehicle is connected with the control center through the network, the intelligent road cone can be connected with the vehicle through the control center, and data transmission between the intelligent road cone and the vehicle is achieved.
After the intelligent road cone is connected with the vehicle, the step of calculating the distance between the intelligent road cone and the running vehicle in real time according to the position data of the intelligent road cone is shown in fig. 8, and comprises the following steps:
and step S801, connecting the intelligent road cone with an on-board unit in the vehicle.
The vehicle-mounted unit in the vehicle is used for collecting data of the vehicle, sending the data to the control center through the wireless network, and connecting the control center with the intelligent road cone, so that a data transmission channel between the intelligent road cone and the vehicle is opened, and data interaction between the intelligent road cone and the vehicle is realized.
In step S802, speed data and position data of the vehicle are acquired from the on-board unit.
The vehicle-mounted unit contains various data of the vehicle, wherein the data include speed data and position data of the vehicle, the speed data of the vehicle can be read through a speed module of the vehicle, and the position data can be acquired according to a positioning chip built in the vehicle-mounted unit.
And step S803, calculating the position data of the intelligent road cone in real time according to the speed data and the position data of the vehicle to obtain the distance between the intelligent road cone and the running vehicle.
Because the position data of the intelligent road cone is obtained, and the speed data and the position data of the vehicle are obtained through calculation in the step S802, the distance between the intelligent road cone and the running vehicle can be conveniently calculated through the opened data transmission channel. Because the vehicle is in the driving process, the distance between the intelligent road cone and the vehicle can be calculated in real time through a data transmission channel realized through networking.
In the above embodiment, the interaction method of the intelligent road cone is described in terms of whether the intelligent road cone and the vehicle are networked, and it can be seen that the intelligent road cone in the method interacts with other road devices through the built-in related communication module, and analyzes and judges the vehicle running on the road, so that the placement of the intelligent road cone is finally realized, the interaction mode of the intelligent road cone and the intelligent traffic network is increased, and the intelligent degree of the intelligent road cone device is improved.
Corresponding to the embodiment of the above-mentioned intelligent road cone interaction method, the intelligent road cone described with reference to fig. 9 includes:
A control module 903 is arranged in the road cone body 901, and the control module 903 is used for communication and positioning; when the control module 903 receives the interactive instruction, the intelligent road cone executes the method mentioned in the first aspect. A positioning module 904 and a communication module 905 in the control module 903. The positioning module 904 supports GNSS, the communication module 905 supports LTE-V/DSRC/3G/4G, and is compatible with a 5G module, so that information interaction with a cloud center and an On-board Unit (OBU) of an intelligent network automobile can be realized.
In some embodiments, the intelligent road cone body 901 further includes a warning light 906 and a switch module 907. When the intelligent road cone is interacted, the warning lamp 906 can be controlled to send out an obstacle avoidance signal through the switch module 907, and the vehicle is guided to decelerate.
A power wheel 911 and a steering wheel 912 are arranged below the road cone body 901, and the power wheel 911 and the steering wheel 912 are operated to move through an instruction provided by a processing module 909 of the movable base 902, so that the intelligent road cone is finally moved to a specified position.
According to information such as the location of intelligence way awl, portable base 902 carries out the information interaction with the cloud center, and the safety distance with being close the vehicle is discerned and is prejudged before putting the way awl based on the cloud center, assesses the safe risk of putting to the maximize reduces the way awl and puts the influence to highway surface traffic.
