Description

Technical Field

[0001] This invention relates to the technical field of warning and guidance for highways and road traffic, and in particular to a suspended convoy highway or road sign system and control method. Background Technology

[0002] Ordinary roads and expressways, as the most efficient road systems, carry the majority of daily travel. Due to the large number of vehicles on these roads, vehicle breakdowns or traffic accidents are inevitable, affecting normal traffic flow. Road maintenance may also close some lanes, causing them to become impassable. It's necessary to provide warnings to following vehicles, reminding them to quickly move to other open lanes to guide traffic and prevent congestion or secondary accidents caused by vehicles blindly driving. Current technology involves placing multiple traffic cones in a curved line to close impassable lanes and guide traffic to open lanes. However, this operation requires personnel to move into the middle of the road, which carries certain risks. Furthermore, the warning cones are easily spotted by vehicles, and drivers at a distance are unlikely to see them early, limiting their judgment time. Summary of the Invention

[0003] In order to solve the problems mentioned in the background art, optimize and improve the guidance efficiency of roads and ensure the smooth operation of roads, this invention proposes a suspended convoy highway or road signage system and control method.

[0004] The technical solution adopted in this invention is: a suspended convoy highway or road sign system, comprising N suspended sign devices arranged sequentially on the upper part of the road surface, characterized in that: the suspended sign device includes two vertically standing legs on both sides and a crossbeam at the top, the two legs and the crossbeam forming a "door" shaped frame, a sign is suspended on the crossbeam, and a lateral movement mechanism is provided inside the crossbeam, the lateral movement mechanism drives the sign to move laterally under the crossbeam to change the suspension position; N≥3, the sign below the N suspended sign devices are arranged in a staggered manner to form a guide line.

[0005] Preferably, the suspension indicator is equipped with a communication module, a control module, and a motor drive module for network information transmission. The lateral movement mechanism is driven by a servo motor or a stepper motor. Each suspension indicator has an operation panel or a QR code on its external support leg. Power is supplied via wires to the power lines along the road or on both sides of the road, or to the power cables on the highway. Alternatively, an interface can be reserved for power supply from vehicles on the road.

[0006] Preferably, the communication module includes a network communication unit and a near-field communication Bluetooth unit. The communication unit is used for remote network control, and the Bluetooth unit is used for on-site control by connecting to a mobile phone.

[0007] Preferably, the traversing mechanism is connected to a manual operating device.

[0008] Preferably, the outriggers of the suspension indicator are fixedly connected to the road surface by fasteners, or the lower ends of the two outriggers of the suspension indicator are provided with several wheels.

[0009] A control method for a suspended train-type highway or road signage system as described above includes the following steps:

[0010] 1) Start

[0011] When a parking problem occurs on the road, the indicator system is activated, causing the sign located near the parking location to move to one side of the location, which is the first sign.

[0012] 2) The second sign's movement

[0013] Based on the position of the first sign after it has been moved, the position of the sign closest to the oncoming traffic direction is moved to a position that is laterally L2 away from the first sign, with the direction of deviation being the direction of travel on the road closer to the parking position;

[0014] 3) The following action of the nth sign

[0015] Based on the position of the (n-1)th sign after it has been moved, the position of the sign closest to the oncoming traffic direction is moved to a position that is laterally offset from the first sign by a distance Ln, with the offset direction being the direction of traffic on the road closer to the parking position; Ln>Ln-1,2<n≤N;

[0016] 4) Repeat step 3) until the size of Ln is greater than or equal to the width of the road surface occupied by the parking position. Through steps 1)-4), the signs are evenly arranged along the direction of traffic, and the signs are gradually staggered laterally to form a guide line, making it easier for later vehicles to see them early and prepare to change lanes.

[0017] Preferably, the suspension indicator is equipped with a communication module for network transmission of information, a control module, and a motor drive module. The lateral movement mechanism is driven by a servo motor or a stepper motor to move laterally. An operation panel or a QR code is provided on the outside of the support leg of each suspension indicator.

[0018] Steps 1)-4) are for remote control;

[0019] Highway and road management personnel can remotely control vehicles via the network after discovering parking problems through roadside video surveillance systems or alarms.

[0020] Alternatively, steps 1)-4) are for on-site control.

[0021] Once a person in the parking position notices a parking problem, they can take control on-site via the operation panel on the suspension system. The operation panel has corresponding options set, and the control module has corresponding control programs set.

[0022] Alternatively, on-site control can be achieved by scanning a QR code and connecting to the network via a mobile app; the mobile phone sends control options to the control module, which then sets the corresponding control program. Both remote and on-site control eliminate the need for operators to go to the road surface, offering greater safety than simply placing traffic cones.

[0023] Preferably, the communication module includes a network communication unit and a near-field communication Bluetooth unit. The mobile phone Bluetooth unit is paired and connected with the Bluetooth unit of the hanging indicator, and the mobile phone program realizes the on-site control of steps 1) to 4).

[0024] Preferably, the lateral movement mechanism is connected to a manual operating device located on the outriggers. When a person in the parking position notices a parking problem, they can use the manual operating device to complete steps 1) to 4). The manual operating device is mounted on the outriggers on both sides, allowing the operator to perform the operation from the roadside, ensuring high safety.

[0025] This invention provides a suspended troop-type highway or road signage system and control method. The system consists of several suspended signage devices arranged in a troop-type guidance system on the highway. Near locations where road occupancy occurs, multiple signs on the suspended signage devices are sequentially adjusted in the direction of oncoming vehicles, forming guide lines. These signs are suspended high in the air, allowing oncoming vehicles ample time to change lanes and avoid risks. Furthermore, the system can be controlled remotely or on-site at the roadside, eliminating the need to enter the middle of the road. Operation is risk-free for the operator, ensuring excellent safety. Attached Figure Description

[0037] Example 1: See Figure 1-7 The figure shows a suspended convoy highway or road sign system, including N suspended sign devices arranged sequentially on the road surface. Each suspended sign device includes two vertically standing legs on both sides and a crossbeam at the top. The two legs and the crossbeam form a "gate" shaped frame. Signs are suspended on the crossbeam. A lateral movement mechanism is provided inside the crossbeam. The lateral movement mechanism drives the sign to move laterally under the crossbeam to change the suspension position. N≥3, and the signs under the N suspended sign devices are arranged in a staggered manner to form guide lines.

[0038] The aforementioned suspension indicator is equipped with a communication module, a control module, and a motor drive module for network information transmission. The lateral movement mechanism is driven by a servo motor or a stepper motor. Each suspension indicator has an operation panel or a QR code on its external support leg. Power is supplied via wires to the power lines along the highway or on both sides of the road, or to the power cables on the expressway. Alternatively, a 12V socket can be provided to utilize the power from vehicles on site.

[0039] The communication module includes a network-connected communication unit and a near-field communication Bluetooth unit. The communication unit is used for remote network control, and the Bluetooth unit is used for on-site control via a mobile phone.

[0040] The suspended indicator device is driven by a motor and can be controlled by an operating panel on the outriggers. Alternatively, it can be remotely controlled by traffic management personnel via a network connection control module, or by connecting to a mobile phone via scanning a QR code on-site, or by connecting to a mobile phone via a Bluetooth module on-site.

[0041] Since all N suspended indicator devices in the system are networked, they can transmit signals to each other via the network and form a combined queue for guidance.

[0042] The traversing mechanism includes a drive wire rope system, a slide rail under the crossbeam, and a traversing trolley. The traversing trolley has rollers at its lower part that cooperate with the slide rail. A warning sign is suspended below the traversing trolley. The wire rope system includes two layers of wire rope arranged in a U-shape and connected in a closed manner, and steering wheels at various turning positions of the wire rope. A portion of the horizontally arranged wire rope is located inside the crossbeam, while the vertically arranged wire ropes on both sides are located inside the outriggers on both sides. The lower layer of wire rope inside the crossbeam is fixedly connected to the traversing trolley. A drive motor is connected to the axle of one of the steering wheels. The drive motor is installed inside the outrigger and connected to the adjacent steering wheel via the drive wire rope. This steering wheel is a double-grooved wheel; one groove holds the drive wire rope, and the other groove holds the wire rope that drives the trolley.

[0043] The lateral movement mechanism is connected to a manual operation device.

[0044] The lower ends of the steering wheel axles of the vertically arranged steel wire ropes on both sides extend outside the outriggers and are equipped with operating handles. The operating handles are used for emergency operation when there is no power supply. Normally, they are driven by a motor and connected to the power supply system of the highway and both sides of the road. Interfaces and cables are reserved for direct connection to the power supply on the vehicle.

[0045] Two slide rails, each with a right-angled cross-section, are symmetrically arranged on both sides of the lower part of the crossbeam. The width of the traverse trolley matches the distance between the inner sides of the two slide rails, providing auxiliary guidance for the trolley's movement and preventing it from veering left and right. Rollers are located on both sides of the trolley, on the upper surface of the slide rails. An upward-protruding track bar is located on the upper surface of the slide rails, inside the rollers. This track bar guides the rollers and prevents them from detaching from the track.

[0046] The outrigger includes a base plate, an outer column, and two symmetrically arranged inner columns. The sides of the outer and inner columns are covered with a shell. The space enclosed by the two inner and outer columns forms the sign housing cavity. This cavity is used to conceal the sign when not in use, making it invisible from the road surface.

[0047] The outer column has a rectangular cross-section, and all the steering wheels are installed inside the outer column. The steering wheel axles are supported at both ends on the sides of the outer column. Two through holes are provided at the upper end of the outer column for the transverse passage of the wire rope. Installing the wire rope and steering wheels inside the column and beam as much as possible provides a certain degree of protection for the wire rope system.

[0048] The horizontally arranged steel wire ropes located on the outer side pass through the inside of the crossbeam.

[0049] The lower surface of the traverse trolley body is provided with two symmetrically arranged clamps, which are arranged perpendicular to the crossbeam. The upper end of the suspended warning sign is provided with a horizontal end plate, which is clamped in the clamps. This way, when the sign is subjected to oncoming wind, the end plate can provide higher strength support and ensure the stability of the sign. The two ends of the end plate can be inserted into the gap between the two clamps and the lower surface of the trolley body. The middle of the end plate is vertically connected to the suspension rod, and the lower end of the suspension rod is the sign. The suspension rod adopts a multi-section telescopic structure, which can adjust the suspension height of the sign.

[0050] The two sides of the crossbeam are connected to the sides of the two slide rails by housings.

[0051] One of the outriggers has a toolbox at its lower part, and the operating handle is located inside the toolbox. The outrigger of the suspension indicator is fixedly connected to the road surface by fasteners.

[0052] Example 2: A control method for a suspended train-type highway or road signage system described in the preceding technical solutions and Example 1, comprising the following steps:

[0053] 1) Start

[0054] When a parking problem occurs on the road, the indicator system is activated, causing the sign located near the parking location to move to one side of the location, which is the first sign.

[0055] 2) The second sign's movement

[0056] Based on the position of the first sign after it has been moved, the position of the sign closest to the oncoming traffic direction is moved to a position that is laterally L2 away from the first sign, with the direction of deviation being the direction of travel on the road closer to the parking position;

[0057] 3) The following action of the nth sign

[0058] Based on the position of the (n-1)th sign after it has been moved, the position of the sign closest to the oncoming traffic direction is moved to a position that is laterally offset from the first sign by a distance Ln, with the offset direction being the direction of traffic on the road closer to the parking position; Ln>Ln-1,2<n≤N;

[0059] 4) Repeat step 3) until the size of Ln is greater than or equal to the width of the road surface occupied by the parking position.

[0060] By achieving a uniform arrangement along the driving direction through steps 1)-4), the signs are gradually staggered laterally, forming a guiding line that allows following vehicles to see them early and prepare to change lanes.

[0061] When the suspension indicator is equipped with a communication module, control module, and motor drive module for transmitting information via the network, the lateral movement mechanism is driven to move laterally by a servo motor or a stepper motor, and an operation panel or a QR code is provided on the outside of the support leg of each suspension indicator.

[0062] Steps 1)-4) are for remote control;

[0063] Highway and road management personnel can remotely control vehicles via the network after discovering parking problems through roadside video surveillance systems or alarms.

[0064] Alternatively, steps 1)-4) are for on-site control.

[0065] Once a person in the parking position notices a parking problem, they can take control on-site via the operation panel on the suspension system. The operation panel has corresponding options set, and the control module has corresponding control programs set.

[0066] Alternatively, on-site control can be achieved by scanning a QR code and connecting to the network via a mobile app; the mobile phone sends control options to the control module, which then sets the corresponding control program. Both remote and on-site control eliminate the need for operators to go to the road surface, offering greater safety than simply placing traffic cones.

[0067] When the communication module includes a network communication unit and a near-field communication Bluetooth unit, the mobile phone Bluetooth unit is paired and connected with the Bluetooth unit of the hanging indicator device, and the mobile phone program implements the on-site control of steps 1) to 4).

[0068] The lateral movement mechanism is connected to a manual operating device located on the outriggers. When the system is without power, a person in the parking position can manually operate the device to complete steps 1) to 4) after noticing a parking problem. The manual operating device is installed on the outriggers on both sides, allowing the operator to perform the operation from the roadside when there is no power supply, ensuring high safety.

[0069] Example 3: See Figure 8-9 Example 3 is basically the same as Example 1, and the similarities will not be repeated. The difference is that the lower ends of the two support legs of the suspension indicator in Example 3 are provided with several traveling wheels. When a road problem occurs and the lane is occupied, if there is no system near the occupied location, the road management personnel can remotely activate N suspension indicator devices in the system, start their traveling wheels to travel along the inner edge of the highway and road guardrail towards the location of the problem. After reaching the destination, they line up at equal intervals, and after adjusting them one by one according to the control method in Example 2, the system enters the prompting working state.

[0070] For the edges of highways and roads, grooved tracks that match the width of the walking wheel can be installed. The lower half of the walking wheel is inserted into the grooved track to move, which makes the walking direction more stable.

[0071] In the above embodiments one, two, and three, the accuracy of manually adjusting the position of the suspended sign can be solved. The surface of the crossbeam is marked with a mark corresponding to the center of the lane. Adjusting the suspended sign to the position corresponding to the mark ensures that the center line of the lane corresponding to the sign is maintained. In this embodiment, the mark is a number. Furthermore, in order to reduce the wind resistance of the sign, the non-patterned area inside the sign can be made into an empty or perforated structure.
