detailed description

Below in conjunction with specific embodiment and accompanying drawing, further elaborate the utility model.

The entrances and exits of expressways are generally arranged as a plurality of side-by-side lanes, and the multiple lanes are divided into left and right groups, the right lane is the entrance, and the left lane is the exit. The traffic flow at the entrance and exit of the expressway is unbalanced at different time points. In some time periods, the traffic flow at the entrance is large, and the traffic flow at the exit is small; The side-by-side lanes are fixedly grouped, some lanes are fixedly set as exits, and some lanes are used as vehicle entrances, and the utilization rate of different intersections fluctuates up and down in different time periods, which is a waste of highway resources.

In the prior art, a display screen is hung above each lane of the expressway, and which lanes are determined as the exit or entrance of the vehicle as required, and displayed on the display screen, and a fence is manually placed between the exit lane and the entrance lane. Separate the two lanes and guide the vehicles on both sides to the correct lane, but this method is slow in response, cannot reclassify and adjust the lanes in time according to the road conditions, and the operation is complicated.

The utility model provides a tidal variable lane control device, the device includes a control circuit, the traffic flow signal detection circuit in the control circuit is connected with a traffic flow sensor and a signal processing circuit, and the signal processing circuit is connected with a lane change control circuit , the lane change control loop is connected to the executive mechanism, and the executive mechanism includes a movable fence, a gantry, a two-way display indicating device, a lane change information board, and a ground vehicle indicating device.

The traffic flow signal detection circuit in the utility model is used to detect the traffic flow at the entrance and exit through the traffic flow sensor, and then transmit the detected traffic flow signal to the signal processing circuit for processing, and then pass through the executive mechanism connected to the lane change control circuit , to control the movement of the movable fence.

The device used for lane allocation in the utility model is a movable fence, and there are two movable fences, and the two movable fences are symmetrically arranged in the middle of the road on both sides of the expressway gantry, and the movable fence is parallel to Lane settings. As shown in Figure 6, the movable fence in this technical solution includes a lifting rod equipped with a lifting fence, one end of the lifting rod is arranged on the rotating table through a pin shaft, and an electric push rod is also provided at the pin shaft end of the lifting rod, In order to realize the lifting of the lifting rod, the lower end of the turntable is fixed on the turn bearing through the turn shaft, and a driven bevel gear is arranged between the turn stand and the turn shaft, and the driven bevel gear has a driving bevel gear on the side Driven by a motor to realize the rotation of the lifting rod.

When the signal processing circuit determines the optimal entrance and exit distribution method according to the traffic flow, the lifting poles of the movable fences on both sides of the lane rise, and then turn a certain angle and then descend to connect the main road isolation belt with the isolation fence between the lanes , the movable fence redistributes the lanes and plays a role in guiding the vehicles so that the vehicles can drive into the correct entrance or exit.

In order to remind the driver of the vehicle to choose the correct lane, a lane change information board connected to the signal processing circuit is set up at a certain distance from the expressway to the lane. The information board is used to display the specific allocation method of the lane ahead, which is convenient for the driver to choose in advance right lane. The lane change information board described in this embodiment is an LED display.

A gantry crane is arranged above the lane, and a two-way display and indicating device connected to the signal processing circuit is suspended below the gantry crane, and the two-way display and indicating device is arranged above each lane. The two-way display indicating device is used to display to both sides of the lane whether the lane is used for vehicle entry or exit. In this embodiment, the two-way display indicating device is a display panel with LED lights on both sides.

In order to further remind the vehicle driver to select the correct lane as the exit or entrance, a ground vehicle indication device connected to the signal processing circuit is provided on the road surface of the expressway in front of each lane, which is used to further remind the vehicle driver of the current driving position. The lane corresponding to the lane is used for vehicle entry or vehicle exit. In this embodiment, several arrow-shaped LED indicator lights embedded in the ground are used as the vehicle driving indicator on the ground, and the direction of the arrow marks the direction in which the vehicle can travel.

When the signal processing loop controls the redistribution of the lanes by the movable fence, the signal processing loop simultaneously sends signals to the lane change information board, the two-way display indicating device and the ground vehicle indicating device, so that they can display the information that matches the state of each exit and entrance. Prompt information.

As shown in Figure 2, when there are more vehicles entering the expressway during the rush hour in the morning than leaving the expressway, the traffic flow signal detection loop transmits the traffic flow information to the signal processing loop, and the signal processing loop analyzes the traffic flow information and converts The six lanes shown in Figure 2 are divided into two groups, of which the four lanes on the right are entrances and the two lanes on the left are exits. At this time, the signal processing loop transmits the grouping information of the lanes to the lane change control loop. After receiving the lane grouping information sent by the signal processing loop, the lane change control loop controls the movement of the movable fence to separate the two groups of lanes. Simultaneously, the lane change controller controls the two-way display indicating device on the gantry to display whether the passage is an entrance or an exit, so as to prompt the vehicle driver. At this time, the lane change controller controls the information displayed on the lane change information board to make further adjustments, so as to remind the vehicle driver to choose the correct lane to travel. Simultaneously, the lane change control loop also controls the ground vehicle indication device on the road ahead of each channel to change the display information, and correctly reflect whether the lane is an exit or an entrance.

As shown in Figure 3, when the number of vehicles entering the expressway is less than the number of vehicles leaving the expressway, the traffic flow signal detection loop transmits the traffic flow information to the signal processing loop, and the signal processing loop analyzes the traffic flow information, as shown in Figure 3 The six lanes shown are divided into two groups, where the two lanes on the right are entrances and the four lanes on the left are exits. At this time, the signal processing loop transmits the grouping information of the lanes to the lane change control loop. After the lane change control loop receives the lane grouping information sent by the signal processing loop, it controls the lifting rod of the movable fence to rise, rotate at a certain angle, and then descend. , to realize the recurring division of lanes. At the same time, the lane change controller controls the two-way display indicating device, the information on the lane change information board and the ground vehicle indicating device to change the colored information to guide the vehicle driver to choose the correct lane to drive.

When the number of entering vehicles and leaving vehicles at the entrance and exit of the expressway is close, the method shown in Figure 4 is used to divide the lanes into two groups evenly.

The movable fence adopted in this technical solution adopts the process of raising, rotating and descending to realize the division of the lane, and its purpose is to realize the movement of the fence. Other types of movement methods in the prior art can also realize the movement of the fence, and should be considered within the scope of protection of this patent.
