Description
Technical Field
The application belongs to the technical field of intelligent traffic, and particularly relates to a traffic control instruction transmission processing method and device and electronic equipment.
Background
In the field of traffic management, in order to improve the utilization rate of road space, traffic management departments increase the management capacity of road traffic, and the utilization rate of roads is improved by matching with signal control, variable guide lanes and the like.
In the related art, in the implementation of signal control, the control of a signal lamp control system is generally self-adaptive, networked and coordinated between intersections. On the basis, a variable guide road (the lane guide changes between left turning, right turning and straight going) is added, and the lane guide is adjusted through a variable lane control system, so that the utilization rate of the road is improved. In addition, an electronic police system is also involved in traffic management, the electronic police system realizes illegal snapshot function through a video triggering mode, the video triggering mode adopts an image processing and analyzing technology to position and track the vehicle in the video, so that the analysis and judgment of the motion track of the vehicle are realized, various illegal behaviors such as red light running and retrograde driving are judged, and automatic snapshot recording is carried out.
At present, the variable guide road is generally a fixed-time variable road, namely, according to the tidal condition of the road, the traffic direction of the road is adjusted in a fixed time period, so as to increase the traffic capacity of the direction with higher traffic flow pressure. Because the control of the variable lane control system is generally adjusted and changed in a fixed time period, the signal lamp control system and the electronic police system can be adjusted according to a defined time period to adapt to the change of the corresponding driving direction of the variable lane.
However, as the traffic flow is continuously increased and the traffic flow is changed along with the change of factors such as weather, holidays, accidents and the like, the original variable roads in fixed time periods can not meet diversified traffic flows slowly. Thus, as demand continues to increase, adaptive variable lanes are emerging, as well as manual control of variable roads to address traffic ambiguities.
When the self-adaptive variable lane and the manual control variable lane appear, based on the existing signal lamp control system and the electronic police system, the problem is that the signal control system cannot identify the lane which is variable at any time, so that the signal control system acquires inaccurate data, the signal control cycle is disordered, and the signal control system is disordered while the variable lane is changed. For a variable lane which is irregularly changed, the electronic police system can only close the monitoring of the lane in order to reduce the screening workload caused by false snapping.
And with the continuous increase of traffic holding quantity, after the traffic pressure is derived from the continuous increase of the demand of self-adapting or manually controlling the vehicle side lane, the smooth butt joint is carried out on each system, so that the fusion becomes a new practical demand and a new development direction.
The above is only for the purpose of assisting understanding of the technical aspects of the present invention, and does not represent an admission that the above is prior art.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail below. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without making any creative effort, shall fall within the protection scope of the present application.
As described in the background art, as the traffic flow is continuously increased and the traffic flow is changed according to factors such as weather, holidays, accidents, etc., the original fixed time period variable roads have been slowly insufficient for diversified traffic flows. Thus, as demand continues to increase, adaptive variable lanes are emerging, as well as manual control of variable roads to address traffic ambiguities.
When the self-adaptive variable lane and the manual control variable lane appear, based on the existing signal lamp control system and the electronic police system, the problem is that the signal control system cannot identify the lane which is variable at any time, so that the signal control system acquires inaccurate data, the signal control cycle is disordered, and the signal control system is disordered while the variable lane is changed. For a variable lane which is irregularly changed, the electronic police system can only close the monitoring of the lane in order to reduce the screening workload caused by false snapping. In the implementation of traffic control, smooth butt joint is performed on all systems, so that fusion becomes a new practical requirement and development direction.
In view of the above, the application provides a traffic control instruction transmission processing method, which is beneficial to the coordination control of a signal lamp control system and a variable lane control system, and meets the requirements of smooth docking and fusion of the systems.
In an embodiment, as shown in fig. 1, the method for processing transmission of traffic control commands includes:
step S110, sensing the change state of lane guidance based on the interaction with a variable lane control system;
as shown in fig. 2, in this embodiment, the method is implemented based on the traffic control instruction transmission processing server (for convenience of description, hereinafter referred to as transmission processing server) in fig. 2;
in this embodiment, the transmission processing server interacts with the lane change control system to sense the changing state of the lane guidance, for example, lane A, B, N is a guidance variable lane, and in this step, the changing state of the lane guidance, specifically, lane A, B, N guidance, is sensed to be changed.
Then, performing step S120, performing validity judgment on the change state of the lane guidance based on a preset rule, and transmitting a preset first instruction to the signal lamp control system when the change of the lane guidance is judged to be valid, so that the signal lamp control system calls and implements a preset control scheme matched with the lane guidance change based on the first instruction;
in an actual scene, the triggering manner of the lane guidance change may be manually operated triggering or automatically triggered (for example, the variable lane control system may be specifically configured, and automatically triggered according to the detected traffic flow change); however, the manual operation may have experimental operation or misoperation, and if the related instructions are directly processed and transmitted, unnecessary traffic control confusion may be caused.
In order to avoid such a situation to a certain extent, in step S120, validity judgment is performed based on a preset rule, and when the judgment is valid, relevant transmission processing is performed, as a specific implementation manner, in this embodiment, validity judgment is performed on a change state of lane guidance based on a preset rule, specifically:
after the transmission processing server senses the lane guide change, when the transmission processing server does not sense other lane guide change operation within a preset time length buffer period (because if the operation is a test or a misoperation, the recovery operation is generally carried out immediately), the change of the lane guide is judged to be effective,
otherwise, the change of the lane guidance is judged to be invalid (for example, the recovery operation is carried out in time), and it is easy to understand that the transmission processing of the relevant instruction is not carried out when the change of the lane guidance is judged to be invalid.
In addition, it should be noted that the current signal lamp control system can receive an instruction from an external system to perform the calling execution of the preset control scheme. According to the technical scheme, the purpose of coordinated control of the signal lamp control system and the variable lane control system can be achieved only by carrying out demand adaptation according to application demands and development documents of the specific signal lamp control system.
According to the technical scheme, the change state of lane guidance is sensed, effectiveness judgment is conducted on the change state of the lane guidance based on the preset rule, when the change of the lane guidance is judged to be effective, the preset first instruction is transmitted to the signal lamp control system, so that the signal lamp control system calls and implements the preset control scheme matched with the lane guidance change based on the first instruction, compared with the prior art, the scheme is beneficial to coordination control of the signal lamp control system and the variable lane control system, and smooth butt joint and fusion requirements of the system are met.
To facilitate understanding of the technical solutions of the present application, the technical solutions of the present application will be described below with reference to another embodiment.
In this embodiment, similarly, step S210 is performed first, and the change state of the lane guidance is sensed based on the interaction with the variable lane control system;
in this embodiment, based on a specific application scenario, there are two ways to realize the state perception of the variable lane, which are described below:
in one scenario, when the variable lane control system is triggered to change the state of the variable lane, the variable lane control system will push a guidance change message to the traffic control instruction transmission processing server, as shown in fig. 3, at this time, the transmission processing server receives the guidance change message pushed by the variable lane control system, and analyzes the guidance change message to obtain the change state of the lane guidance;
in another scenario, the variable lane control system does not have a message pushing capability, and at this time, the traffic control instruction transmission processing server may be specifically configured, as shown in fig. 4, the transmission processing server performs timing scanning on the guidance state description interface of the variable lane control system, and analyzes the scanned information to obtain the change state of the lane guidance.
After the change state of the lane guidance is sensed in the step S210, continuing to perform a step S220, performing validity judgment on the change state of the lane guidance based on a preset rule, and transmitting a preset first instruction to the signal lamp control system when the change of the lane guidance is judged to be valid, so that the signal lamp control system calls and implements a preset control scheme matched with the change of the lane guidance based on the first instruction;
in step S220, the related content of the validity judgment is introduced in the foregoing embodiments, and is not described herein again.
In step S220, as shown in fig. 3 and 4, in this embodiment, the signal lamp control system invokes and implements a preset control scheme matching the lane guidance change based on the first instruction, including:
according to the first instruction, the signal machine in the signal lamp control system triggers and executes the preset lane phase lock to change lane guidance (referring to fig. 2, the actual guidance sign corresponding to the variable lane changes).
As can be easily understood by those skilled in the art, in the application scenario of the present application, as shown in fig. 2, there are generally four sections at the intersection, and each section may be provided with a variable lane, so that a corresponding lane phase lock of the signal should be set for each variable lane, and after the corresponding phase lock is triggered, a corresponding signal operation scheme is made.
Furthermore, in this embodiment, the signal lamp control system calls and implements a preset control scheme matching the lane guide change based on the first instruction, further comprising,
the signal machine in the signal lamp control system calls and implements a preset operation scheme (such as a control operation scheme required by the operation change of the red and green signal lamps shown in figure 2) matched with the lane guidance change according to the first instruction.
In addition, as shown in fig. 2 to 4, the technical solution of the present embodiment, for the electronic police system, further includes,
and when the change of the lane guidance is judged to be effective, transmitting a preset second instruction to the electronic police system so that the electronic police system calls and implements a preset snapshot scheme matched with the lane guidance change based on the second instruction.
In this embodiment, the electronic police system calls and implements a preset snapshot scheme matched with the current lane guidance change based on the second instruction, specifically:
and the electronic police front-end camera or the electronic police central control server (not shown in the figure 2) calls and implements a preset snapshot scheme matched with the lane guide change based on the second instruction.
It should be noted that, the electronic police system in the market at present is only a function of capturing an illegal action and a bayonet because of a single working mode, and lacks an open external system docking function. In order to realize the technical scheme of the application, the electronic police system needs to have the function of receiving the external instruction and the capability of providing a multi-plan mechanism.
In the early development process of the intelligent transportation industry, each manufacturer considers the upgrade optimization and the perfection of the system of the manufacturer and mainly makes a product of the manufacturer. However, with the development trend of science and technology, each system is no longer an independent system, and especially for the intelligent transportation industry, the equipment and the system on the road must be capable of linkage coordination to meet the current traffic demand. According to the trend, the fusion and coordination of three systems of an electric alarm, a signal and a variable lane are just about to be faced at present, and the operation of the intersection can be stable.
The technical scheme of the application mainly solves the problem that the national intelligent traffic market is about to face at present, namely how to realize the integration of an electronic police system, a signal control system, a variable lane system and three systems. Different from single data fusion, the fusion of the three systems can be perfectly operated only by mutually coordinating and butting the external field hardware and the central system.
At present, no direct coordination mode can be achieved among three systems in the market, and the technical scheme of the application essentially provides a coordination method among the three systems, and solves the problem of integration of the three systems through a traffic control instruction transmission processing system of the implementation method.
In one embodiment, the present application provides a traffic control instruction transmission processing apparatus, including:
the sensing module is used for sensing the change state of lane guidance based on interaction with the variable lane control system;
and the judging and processing module is used for judging the effectiveness of the change state of the lane guide based on a preset rule, and transmitting a preset first instruction to the signal lamp control system when the change of the lane guide is judged to be effective, so that the signal lamp control system calls and implements a preset control scheme matched with the lane guide change based on the first instruction.
With regard to the traffic control instruction transmission processing device in the above-described related embodiment, the specific manner in which each module performs the operation has been described in detail in the embodiment related to the method, and will not be described in detail here.
Fig. 5 is a schematic structural diagram of an electronic device according to an embodiment of the present application, and as shown in fig. 5, the electronic device 400 includes:
a memory 401 having an executable program stored thereon;
a processor 402 for executing the executable program in the memory 401 to implement the steps of the above method.
With respect to the electronic device 400 in the above embodiment, the specific manner of executing the program in the memory 401 by the processor 402 thereof has been described in detail in the embodiment related to the method, and will not be elaborated herein.
The above description is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
