Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent transportation, and particularly relates to a rapid passing control system and method for highway toll stations. Background Art

[0002] The statements in this part only provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] As the entrances and exits of highways and urban expressways, toll stations are responsible for collecting vehicle tolls and guiding traffic flow. However, with the rapid increase in the number of vehicles, toll stations often become congested during peak hours, seriously affecting traffic efficiency and road safety. The reasons for congestion mainly include vehicle concentration, low toll collection efficiency, unreasonable lane allocation, backward technical means, and insufficient emergency handling capabilities; the lane allocation of some toll stations is not flexible enough to be dynamically adjusted according to the actual traffic flow, resulting in congestion in some lanes while other lanes are idle; there is a lack of effective technical means to monitor and predict traffic flow in real time, and no countermeasures can be taken in advance; in the face of emergencies such as vehicle breakdowns and traffic accidents, the emergency handling capabilities of toll stations are insufficient, further exacerbating congestion. The congestion at toll stations not only reduces the road passing efficiency, increases the commuting time, but also may lead to traffic accidents, causing adverse effects on safety and the environment. Summary of the Invention

[0004] In view of the above problems, the present invention provides a rapid passing control system and method for highway toll stations, which can change the driving direction of lanes according to the real-time traffic flow characteristics on the road section, improving the road utilization rate and passing capacity.

[0005] To achieve the above object, the present invention is realized by the following technical solutions:

[0006] In a first aspect, the present invention provides a rapid passing control system for highway toll stations, including: a traffic volume detection device and a diversion device; the diversion device consists of a control unit and a diversion conversion device; the traffic volume detection device is used to count the traffic volume of each lane; and transmit the counted traffic volume data to the control unit, and the control unit performs data processing and decision-making, and sends control instructions to the diversion conversion device;

[0007] The diversion conversion device consists of an alarm, a servo motor, a driving wheel, a lane indication sign, a rotatable column, and a diversion conversion guardrail; the lane indication sign is arranged on the top of the diversion conversion guardrail, the servo motor is arranged at one end of the diversion conversion guardrail, and the rotatable column is arranged at the other end of the diversion conversion guardrail; a driving wheel is arranged below the servo motor, and an alarm is arranged above the servo motor;

[0008] The traffic volume detection device, the alarm, the servo motor and the lane indication sign are all connected to the control unit.

[0009] Furthermore, the control unit includes a power supply module, a servo controller, a servo driver, a remote control module and a warning and pre-warning module: the power supply module is respectively connected to the servo controller, the servo driver, the remote control module and the warning and pre-warning module, and provides power.

[0010] Furthermore, the remote control module includes an automatic remote control and a manual remote control. The automatic remote control establishes wireless communication with the traffic volume detection device; both the automatic remote control and the manual remote control are connected to the servo controller, and are used to provide traffic volume data information for the servo controller. The servo controller is respectively connected to the servo driver and the warning and pre-warning module.

[0011] Furthermore, the servo driver is connected to the servo motor and sends control instructions to make the servo motor work.

[0012] Furthermore, the warning and pre-warning module includes a plurality of induction lamp contactors and alarm contactors; the alarm contactor is connected to the alarm and is used to control the alarm to work; the induction lamp contactor is connected to the lane indication sign.

[0013] Furthermore, the driving wheel is a rotating wheel that can rotate 360°. The driving wheel controls the direction and provides driving force through the servo motor; a driven wheel is arranged in the middle of the lower part of the diversion conversion guardrail to provide a supporting effect for the diversion conversion guardrail.

[0014] Furthermore, the lower end of the rotatable column is fixed on the ground, and the diversion conversion guardrail is rotatably connected to the rotatable column.

[0015] In a second aspect, the present invention also provides a control method for a fast-pass control system of a highway toll station, including:

[0016] S1. System initialization, and the traffic volume detection device is in a detection state;

[0017] S2. Determine whether the signal source is the automatic remote control or the manual remote control;

[0018] S3. If the signal source is the manual remote control, the alarm of the toll station diversion device and the lane indication sign work. At the same time, the servo driver acts according to the set instructions of the servo controller, drives the diversion conversion guardrail to rotate, and completes the lane conversion;

[0019] S4. If the signal source is an automatic remote control, the servo controller determines the abnormal conditions, such as whether the conversion conditions are met, based on the driving environment detected by the traffic volume detection device and the traffic volume detection signal.

[0020] If the conditions are met, the alarm of the toll station diversion device and the lane indication signs operate. At the same time, the servo driver acts according to the set instructions of the servo controller, driving the diversion conversion guardrail to rotate to complete the lane conversion.

[0021] If the conditions are not met, the toll station diversion device remains in the detection state, and the diversion conversion guardrail does not rotate.

[0022] S5. When the abnormal conditions end, the toll station diversion device resets its actions, the alarm and the lane indication signs are turned off, and the diversion conversion guardrail is reset.

[0023] Furthermore, the conversion conditions are as follows:

[0024] When the traffic volume of a certain lane is detected to be lower than the set threshold, that lane will be closed to reduce resource waste.

[0025] When the driving environment monitoring device detects that the road surface is slippery or there is an accident, the affected lane will be closed.

[0026] During the traffic peak period, when there is a significant difference in the traffic volume in two directions, the system will change the oncoming lane to a tidal lane through the toll station diversion device.

[0027] Furthermore, the significant difference conditions are as follows:

[0028] When L 1 / n 1 >L 2 / n 2 , one lane is added at the entrance and one lane is reduced at the exit;

[0029] When L 1 / (n 1 +1)>L 2 / (n 2 -1), one more lane is added at the entrance and one more lane is reduced at the exit;

[0030] Among them, L 1 is the number of inbound vehicles, L 2 is the number of outbound vehicles, n 1 is the number of inbound lanes, and n 2 is the number of outbound lanes.

[0031] Compared with the prior art, the advantages and positive effects of the present invention are:

[0032] Beneficial effects of the present invention

[0033] The control system provided by the present invention can change the driving direction of lanes according to the real-time traffic flow characteristics on the road section, and can change the oncoming lanes into tidal lanes. For example, during the traffic peak period, when there are significant differences in the traffic volumes in two directions, lane adjustment is carried out, effectively improving the utilization efficiency of road resources and alleviating traffic congestion. By counting the traffic volumes of each lane through traffic volume detection devices, the control unit flexibly changes the driving direction of the lanes according to data processing and decision-making, solving the problem that the lane allocation of some toll stations is not flexible enough and cannot be dynamically adjusted according to the actual traffic volume, and avoiding the situation where some lanes are congested while other lanes are idle.

[0034] The control method of the present invention can, when the driving environment monitoring device discovers that the road surface is slippery or an accident occurs on the road, timely close the affected lanes, avoiding the further aggravation of traffic chaos caused by emergencies, and enhancing the emergency handling ability of the toll station in the face of emergencies. An automatic remote controller is set up to establish wireless communication with the traffic volume detection device, and it can automatically judge whether the conversion conditions are met and perform lane conversion according to the detected driving environment and traffic volume detection signals, realizing intelligent traffic management and reducing manual intervention. When the traffic volume of a certain lane is detected to be lower than the set threshold, that lane is closed, avoiding the ineffective occupation and waste of resources.
