Description

Technical Field

[0001] This invention relates to the field of highway technology, and in particular to a method and guidance system for identifying and guiding highway construction work zones. Background Technology

[0002] Traffic volume and speed are high on highways, making road construction highly dangerous. Therefore, traffic safety management during road construction is a core aspect of overall construction safety management. Safety management of highway construction work areas is a key focus of construction safety management. Currently, in highway construction work area safety management, there is a general lack of oversight regarding whether the placement of signs and cones complies with the work area zoning requirements of "Road Traffic Signs and Markings Part 4: Work Areas" (GB5768.4). Furthermore, there are no simple and effective technical guidelines for on-site construction personnel to make timely adjustments.

[0003] Currently, there are products and solutions that use equipment positioning information to record the placement of signs and plaques. However, these products and solutions only record positioning information and cannot judge the compliance of the placement, so they still cannot assist on-site construction personnel in carrying out relevant safety management work.

[0004] Therefore, a method and guidance system for identifying and guiding highway construction work zones are needed. Summary of the Invention

[0005] This invention provides a method and guidance system for identifying and guiding road construction work zones on highways, which at least solves the technical problem that existing products and solutions that use equipment positioning information to record the placement of signs and markers cannot determine the conformity of the placement.

[0006] According to one aspect of the present invention, a method for identifying the zoning of highway road construction work areas is provided, comprising:

[0007] After all safety facilities are in place, information on road construction operations is obtained, wherein the safety facilities include safety equipment with positioning function;

[0008] The type of work area is identified based on the road construction operation information;

[0009] The location of equipment in the work area is identified based on the road construction operation information;

[0010] The spacing between safety devices with positioning functions is calculated based on the type of work area and the placement of equipment in the work area.

[0011] The equipment spacing is divided into zones according to the type of work area;

[0012] The results of the partitioning are used to identify potential security risks.

[0013] Optionally, it also includes reminding on-site management personnel to rearrange safety facilities according to the identified safety hazards, until they are placed in accordance with the specifications.

[0014] Optionally, the information on highway construction operations includes: equipment information of safety devices with positioning function, highway name, highway number, type of work area, direction of work area, original speed limit of the road, number of closed lanes, number of borrowed opposite lanes, and distance of median strip opening.

[0015] Optionally, the device spacing is the distance between a first straight line and a second straight line. The first straight line is a straight line perpendicular to the center line of the highway for a safety device with positioning function, and the second straight line is a straight line perpendicular to the center line of the highway for a safety device with positioning function adjacent to the safety device.

[0016] Optionally, during the placement of safety facilities, safety equipment with positioning function may be used to replace at least the starting and ending points of traditional safety facility placement; the positions located in front of and behind the work area; and any position behind the work area.

[0017] Optionally, the location of equipment in the work area can be identified based on the road construction operation information, specifically including:

[0018] Step S31: Obtain the device information of the safety device with positioning function, and convert the latitude and longitude in the device information into planar distance coordinates;

[0019] Step S32: Fit the safety equipment with positioning function with the station number to obtain the fitted station number;

[0020] Step S33: Sort all fitted station numbers;

[0021] Step S34: Determine if there are identical station numbers in the fitted station numbers. If identical station numbers are found, proceed to the next step; otherwise, the process of identifying the placement location of equipment in the work area ends.

[0022] Step S35: Determine if the same station number is the starting station number. If the same station number is not the starting station number, re-acquire the fitted station number and return to step S34. If the same station number is the starting station number, determine if the work area direction is the uphill direction. If the work area direction is the uphill direction, proceed to step S38; otherwise, proceed to step S36. The uphill direction is the direction in which the highway station number value increases; the downhill direction is the direction in which the highway station number value decreases.

[0023] Step S36: Determine whether the same chainage is the end chainage. If the same chainage is not the end chainage, proceed to step S37. If the same chainage is the end chainage, determine whether the direction of the work area is the upward direction. If the direction of the work area is the upward direction, proceed to step S39; otherwise, proceed to step S38.

[0024] Step S37: Determine whether the direction of the work area is upward. If the direction of the work area is upward, proceed to step S39; otherwise, proceed to step S38.

[0025] Step S38: Calculate the distance between each piece of equipment and the station number of the fitted station, arrange all the calculated distances in ascending order in the direction of the work area, and then proceed to step S310.

[0026] Step S39: Calculate the distance between each piece of equipment and the station number of the fitted station, sort all the calculated distances in descending order as the direction of the work area, and then proceed to step S310.

[0027] Step S310: Determine whether all equipment with the same station number should be reordered after sorting the fitted station numbers. If all equipment is reordered, the equipment placement location in the work area is identified; otherwise, return to step S34.

[0028] Optionally, the spacing between safety devices with positioning functions is calculated based on the type of the work area and the placement of the equipment in the work area, specifically including:

[0029] Determine whether the work area falls into one of the following four categories: inner side of closed main line, outer side of closed main line without using lanes, outer side of closed main line using the opposite lane, or outer side of closed main line using the same-direction sidewalk. If it falls into one of the four categories, calculate the spacing of the equipment in the main line direction based on the equipment arrangement order and equipment spacing formula. If it does not fall into any of the four categories, arrange the equipment according to the standard signage layout diagram, without calculating the equipment spacing.

[0030] Optionally, the device spacing d ij The calculation formula is:

[0031]

[0032] In the above formula, the distance d between device i and device j in the main line direction is... ij That is, the vectors of station numbers Km and Kn in the plane distance coordinates XOY. The distance is calculated as follows: Km is the starting station of the work area fitted by the equipment, and Kn is the ending station of the work area fitted by the equipment. If all equipment is fitted to the same station Kn, then based on the up and down information of the work area, the up line will take Kn+1 as the ending point, and the down line will take Kn-1 as the ending point. Let x be the vector of device i and device j in the plane distance coordinates XOY. kn y kn Let x represent the station number Kn along the X and Y axes in the XOY coordinate system. km y km Let x be the X and Y values ​​of the station number Km in the XOY coordinate system. j y j The values ​​of the X and y axes of device j in the XOY coordinate system, x i y i Let X and Y be the values ​​of device i in the XOY coordinate plane.

[0038] A work area type partitioning unit, which is used to partition the equipment spacing according to the type of work area;

[0039] The safety hazard identification unit is used to identify safety hazards in the results of the partitioning.

[0040] Optionally, an alarm unit is used to remind on-site management personnel to rearrange safety facilities according to the results of safety hazard identification, until they are arranged in accordance with the specifications.

[0041] According to another aspect of the present invention, a computer-readable storage medium is also provided, the computer-readable storage medium including a stored program, wherein, when the program is executed, it controls the device where the computer-readable storage medium is located to execute the highway road construction operation zoning and identification method described in any one of the above embodiments.

[0042] According to another aspect of the present invention, a processor is also provided, the processor being used to run a program, wherein the program, when running, executes the highway road construction operation zoning and identification method described in any one of the preceding embodiments.

[0043] Compared with existing technologies, the present invention has the following advantages:

[0050] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0051] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0052] Example 1

[0053] According to an embodiment of the present invention, an embodiment of a method for identifying the zoning of highway road construction operations is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0054] like Figure 1 As shown, the method for identifying the zoning of highway construction work areas includes the following steps:

[0055] Step S1: After all safety facilities are placed, obtain information on road construction operations, including safety facilities with positioning functions.

[0056] As an optional embodiment, the information for highway road construction operations includes: equipment information of safety equipment with positioning function, highway name, highway number, type of work area, direction of work area, original speed limit of the road, number of closed lanes, number of borrowed opposite lanes, and distance of median strip opening.

[0057] The equipment information should include at least the following: equipment number, longitude, latitude, highway name, highway number, and direction of travel (up or down).

[0058] As an optional embodiment, during the placement of safety facilities, safety equipment with positioning function is used to replace at least the starting point and ending point of traditional safety facility placement; the position in front of and behind the work area; and any position behind the work area.

[0059] Specifically, such as Figure 3 As shown, when placing cones during road construction work on highways, safety equipment with positioning function is used to replace the traditional safety facilities at the starting and ending points, as well as some cones located in front of and behind the work area. Among the safety facilities located behind the work area, at least one cone is placed between two adjacent safety facilities, with the direction of travel along the highway as the front and the direction of travel against the highway as the rear.

[0060] Among them, safety equipment with positioning function can be cones with positioning function. By combining the positioning information of cones and other safety facilities with the highway construction operation zoning identification method of this invention, the conformity of the placement of cones and other safety facilities can be judged, and the guidance system can prompt on-site management personnel, effectively improving the safety management level of highway construction. The use of safety equipment with positioning function partially replaces traditional equipment, but does not completely replace it, and the traditional equipment can still be used, without wasting resources.

[0061] Step S2: Identify the type of work area based on the road construction operation information.

[0062] As an optional embodiment, the types of work areas include: closing the inner side of the main line, closing the outer side of the main line without borrowing lanes, closing the outer side of the main line with borrowing the opposite lane, closing the outer side of the main line with borrowing the same-direction temporary road, ramps, and other types (middle lane of the main line, acceleration lane entrance, deceleration lane entrance, adjacent lane of the acceleration lane, adjacent lane of the deceleration lane, and special work areas requiring traffic engineering demonstration).

[0063] Step S3: Identify the location of equipment in the work area based on the road construction operation information.

[0064] As an optional embodiment, such as Figure 2 As shown, step S3 specifically includes:

[0065] Step S31: Obtain the device information of the safety device with positioning function, and convert the latitude and longitude in the device information into planar distance coordinates (x, y), with the conversion rule being that every 0.000001° corresponds to 0.111m;

[0066] Step S32: Fit the safety equipment with positioning function with the station number to obtain the fitted station number;

[0067] Step S33: Sort all fitted station numbers;

[0068] Specifically, determine whether the work area direction is the uphill direction. If so, sort the fitted station numbers in ascending order; otherwise, sort them in descending order. The uphill direction is the direction in which the highway station numbers increase, and the downhill direction is the direction in which the highway station numbers decrease.

[0069] Step S34: Determine if there are identical station numbers in the fitted station numbers. If identical station numbers are found, proceed to the next step; otherwise, the process of identifying the placement location of equipment in the work area ends.

[0070] Step S35: Determine if the same station number is the starting station number. If the same station number is not the starting station number, then re-acquire the fitted station number and return to step S34. If the same station number is the starting station number, then determine if the working area direction is the upward direction. If the working area direction is the upward direction, proceed to step S38; otherwise, proceed to step S36.

[0071] Step S36: Determine whether the same chainage is the end chainage. If the same chainage is not the end chainage, proceed to step S37. If the same chainage is the end chainage, determine whether the direction of the work area is the upward direction. If the direction of the work area is the upward direction, proceed to step S39; otherwise, proceed to step S38.

[0072] Step S37: Determine whether the direction of the work area is upward. If the direction of the work area is upward, proceed to step S39; otherwise, proceed to step S38.

[0073] Step S38: Calculate the distance between each piece of equipment and the station number of the fitted station, arrange all the calculated distances in ascending order in the direction of the work area, and then proceed to step S310.

[0074] Step S39: Calculate the distance between each piece of equipment and the station number of the fitted station, sort all the calculated distances in descending order as the direction of the work area, and then proceed to step S310.

[0075] Step S310: Determine whether all equipment with the same station number should be reordered after sorting the fitted station numbers. If all equipment is reordered, the equipment placement location in the work area is identified; otherwise, return to step S34.

[0076] Step S4: Calculate the equipment spacing of safety equipment with positioning function based on the type of work area and the placement of equipment in the work area.

[0077] The equipment spacing is the distance between the first straight line and the second straight line. The first straight line is a straight line perpendicular to the center line of the highway for a safety device with positioning function, and the second straight line is a straight line perpendicular to the center line of the highway for a safety device with positioning function adjacent to the safety device.

[0078] As an optional embodiment, the equipment spacing of the safety equipment with positioning function is calculated based on the type of work area and the placement of equipment in the work area, specifically including:

[0079] Determine whether the work area falls into one of the following four categories: inner side of closed main line, outer side of closed main line without using lanes, outer side of closed main line using the opposite lane, or outer side of closed main line using the same-direction sidewalk. If it falls into one of the four categories, calculate the spacing of the equipment in the main line direction based on the equipment arrangement order and equipment spacing formula. If it does not fall into any of the four categories, arrange the equipment according to the standard signage layout diagram, without calculating the equipment spacing.

[0080] Specifically, such as Figure 3 As shown, the distance d between device i and device j in the main line direction ij That is, the direction of the vector from station Km to station Kn. The distance is calculated as follows: Km is the starting station number of the work area fitted by the equipment, and Kn is the ending station number fitted by the equipment. If all equipment is fitted to the same station number Kn, then based on the up and down information of the work area, the up line takes Kn+1 as the ending point, and the down line takes Kn-1 as the ending point.

[0081] Equipment spacing d ij The calculation formula is:

[0082]

[0083] In the above formula, the distance d between device i and device j in the main line direction is... ij That is, the vectors of station numbers Km and Kn in the plane distance coordinates XOY. The distance is calculated as follows: Km is the starting station of the work area fitted by the equipment, and Kn is the ending station of the work area fitted by the equipment. If all equipment is fitted to the same station Kn, then based on the up and down information of the work area, the up line will take Kn+1 as the ending point, and the down line will take Kn-1 as the ending point. Let x be the vector of device i and device j in the plane distance coordinates XOY. kn y kn Let x represent the station number Kn along the X and Y axes in the XOY coordinate system. km y km Let x be the X and Y values ​​of the station number Km in the XOY coordinate system. j y j The values ​​of the X and y axes of device j in the XOY coordinate system, x i y i Let X and Y be the values ​​of device i in the XOY coordinate plane.

[0084] Step S5: Divide the equipment spacing into zones according to the type of work area.

[0085] As an optional embodiment, step S5 specifically includes: inserting the device distance calculated in step S4 into the corresponding data structure in step S1, and identifying the lengths of the corresponding S warning area, Ls upstream transition area, H buffer, G working area, Lx downstream transition area, and Z termination area.

[0086] Step S6: Identify security risks in the partitioning results.

[0087] As an optional embodiment, based on the lengths of the S warning zone, Ls upstream transition zone, H buffer zone, G working zone, Lx downstream transition zone, and Z termination zone identified in step S4, and in conjunction with the "Road Traffic Signs and Markings Part 4: Working Zones" (GB5768.4), areas whose lengths do not meet the specifications are identified, thereby identifying places with potential safety hazards.

[0088] As an optional embodiment, it also includes step S7, reminding on-site management personnel to rearrange the safety facilities through safety hazard identification until they are placed in accordance with the specifications.

[0089] Example 2

[0090] According to another aspect of the present invention, a highway road construction work zone identification and guidance system is also provided. This system applies the above-described highway road construction work zone identification and guidance method. The highway road construction work zone identification and guidance system includes:

[0091] The road construction operation information unit is used to acquire road construction operation information. Safety facilities include safety equipment with positioning functions. Information on highway road construction operations includes: equipment information for safety equipment with positioning functions, highway name, highway number, type of work area, direction of work area, original speed limit, number of closed lanes, number of borrowed opposite lanes, and median strip opening distance. Equipment information must at least include: equipment number, longitude, latitude, highway name, highway number, and direction of travel (up or down).

[0092] The work area type identification unit is used to identify the type of work area based on road construction work information. The types of work areas include: closed inner side of the main line, closed outer side of the main line without borrowing lanes, closed outer side of the main line borrowing the opposite lane, closed outer side of the main line borrowing the same-direction temporary road, ramps, and other types (middle lane of the main line, acceleration lane entrance, deceleration lane entrance, adjacent lane of the acceleration lane, adjacent lane of the deceleration lane, and special work areas requiring traffic engineering demonstration).

[0093] The equipment placement location identification unit in the work area is used to identify the placement location of equipment in the work area based on road construction operation information;

[0094] The equipment spacing calculation unit is used to calculate the equipment spacing of safety equipment with positioning function based on the type of work area and the placement of equipment in the work area.

[0095] The work area type partitioning unit is used to partition the equipment spacing according to the type of work area;

[0096] The safety hazard identification unit is used to identify safety hazards in the results of the partitioning.

[0097] As an optional embodiment, the highway construction site zoning identification and guidance system also includes an alarm unit, which is used to remind on-site management personnel to rearrange safety facilities according to the safety hazard identification results until they are placed in accordance with the specifications.

[0098] The alarm unit can remotely alert on-site management personnel via mini-programs, apps, or web pages.

[0099] As an optional embodiment, the highway road construction operation zone identification and guidance system also includes a road construction operation information input unit, which is used by on-site management personnel to input road construction operation information and provide it to the road construction operation information unit. The road construction operation information input unit can input information remotely via mini-programs, apps, or web pages.

[0100] As an optional embodiment, such as Figure 2 As shown, the equipment placement location identification unit in the work area identifies the specific placement locations of equipment in the work area based on road construction operation information, including:

[0101] Step S31: Obtain the device information of the safety device with positioning function, and convert the latitude and longitude in the device information into planar distance coordinates (x, y), with the conversion rule being that every 0.000001° corresponds to 0.111m;

[0102] Step S32: Fit the safety equipment with positioning function with the station number to obtain the fitted station number;

[0103] Step S33: Sort all fitted station numbers;

[0104] Specifically, determine whether the direction of the work area is upward. If so, sort the fitted station numbers in ascending order; otherwise, sort the fitted station numbers in descending order.

[0105] Step S34: Determine if there are identical station numbers in the fitted station numbers. If identical station numbers are found, proceed to the next step; otherwise, the process of identifying the placement location of equipment in the work area ends.

[0106] Step S35: Determine if the same station number is the starting station number. If the same station number is not the starting station number, then re-acquire the fitted station number and return to step S34. If the same station number is the starting station number, then determine if the working area direction is the upward direction. If the working area direction is the upward direction, proceed to step S38; otherwise, proceed to step S36.

[0107] Step S36: Determine whether the same chainage is the end chainage. If the same chainage is not the end chainage, proceed to step S37. If the same chainage is the end chainage, determine whether the direction of the work area is the upward direction. If the direction of the work area is the upward direction, proceed to step S39; otherwise, proceed to step S38.

[0108] Step S37: Determine whether the direction of the work area is upward. If the direction of the work area is upward, proceed to step S39; otherwise, proceed to step S38.

[0109] Step S38: Calculate the distance between each piece of equipment and the station number of the fitted station, arrange all the calculated distances in ascending order in the direction of the work area, and then proceed to step S310.

[0110] Step S39: Calculate the distance between each piece of equipment and the station number of the fitted station, sort all the calculated distances in descending order as the direction of the work area, and then proceed to step S310.

[0111] Step S310: Determine whether all equipment with the same station number should be reordered after sorting the fitted station numbers. If all equipment is reordered, the equipment placement location in the work area is identified; otherwise, return to step S34.

[0112] Step S4: Calculate the equipment spacing of safety equipment with positioning function based on the type of work area and the placement of equipment in the work area.

[0113] The equipment spacing is the distance between the first straight line and the second straight line. The first straight line is a straight line perpendicular to the center line of the highway for a safety device with positioning function, and the second straight line is a straight line perpendicular to the center line of the highway for a safety device with positioning function adjacent to the safety device.

[0114] As an optional embodiment, the equipment spacing calculation unit calculates the equipment spacing of safety equipment with positioning function based on the type of work area and the placement of equipment in the work area, specifically including:

[0115] Determine whether the work area falls into one of the following four categories: inner side of closed main line, outer side of closed main line without using lanes, outer side of closed main line using the opposite lane, or outer side of closed main line using the same-direction sidewalk. If it falls into one of the four categories, calculate the spacing of the equipment in the main line direction based on the equipment arrangement order and equipment spacing formula. If it does not fall into any of the four categories, arrange the equipment according to the standard signage layout diagram, without calculating the equipment spacing.

[0116] Specifically, such as Figure 3 As shown, the distance d between device i and device j in the main line direction ij That is, the direction of the vector from station Km to station Kn. The distance is calculated as follows: Km is the starting station number of the work area fitted by the equipment, and Kn is the ending station number fitted by the equipment. If all equipment is fitted to the same station number Kn, then based on the up and down information of the work area, the up line takes Kn+1 as the ending point, and the down line takes Kn-1 as the ending point.

[0117] Equipment spacing d ij The calculation formula is:

[0118]

[0119] In the above formula, the distance d between device i and device j in the main line direction is... ij That is, the vectors of station numbers Km and Kn in the plane distance coordinates XOY. The distance is calculated as follows: Km is the starting station of the work area fitted by the equipment, and Kn is the ending station of the work area fitted by the equipment. If all equipment is fitted to the same station Kn, then based on the up and down information of the work area, the up line will take Kn+1 as the ending point, and the down line will take Kn-1 as the ending point. Let x be the vector of device i and device j in the plane distance coordinates XOY. kn y kn Let x represent the station number Kn along the X and Y axes in the XOY coordinate system. km y km Let x be the X and Y values ​​of the station number Km in the XOY coordinate system. j y j The values ​​of the X and y axes of device j in the XOY coordinate system, x i y i Let X and Y be the values ​​of device i in the XOY coordinate plane.

[0120] As an optional embodiment, the type partitioning unit of the work area specifically includes: inserting the distance between devices calculated by the device spacing calculation unit into the corresponding type of data structure in step S1, and identifying the lengths of the corresponding S warning area, Ls upstream transition area, H buffer, G work area, Lx downstream transition area, and Z termination area.

[0121] As an optional embodiment, based on the lengths of the S warning zone, Ls upstream transition zone, H buffer zone, G work zone, Lx downstream transition zone, and Z termination zone identified by the type partitioning unit of the work area, and combined with the "Road Traffic Signs and Markings Part 4: Work Zones" (GB5768.4), areas whose lengths do not meet the specifications are identified, thereby identifying places with potential safety hazards.
