DETAILED DESCRIPTION

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0021] Currently, the actual application reliability of road construction is not high. Based on this, the embodiment of the present invention provides a method and device for planning construction routes based on visibility assistance, which can be combined with visibility-assisted construction route planning to ensure the application reliability of actual construction.

[0022] To facilitate understanding of this embodiment, a visibility-assisted route planning and construction method disclosed in an embodiment of the present invention is first introduced in detail. This method can be applied to intelligent control devices such as controllers, host computers, and servers.

[0023] Figure 1 A flow chart of a method for planning and constructing a route based on visibility assistance provided by an embodiment of the present invention.

[0024] Reference Figure 1 , the method mainly includes the following steps: Step S102: Obtain observation data collected by each meteorological station in the area to be constructed and the type of each administrative district.

[0025] Based on the current phase of the pending construction area, information about the area can be obtained, such as the measured data of the meteorological stations within the area and the distribution of administrative districts within the area. For example, administrative districts include officially designated regions such as Northeast China, North China, Northwest China, Southwest China, and Southeast China. The pending construction area can be understood as the geographical area where road construction is planned, including highways, bridges, buildings, and stations. It should be noted that, to facilitate road construction, embodiments of the present invention may have access to corresponding observation data in each area.

[0026] Step S104 : dividing the observation area of each weather station based on the data type of the observation data within the first preset range corresponding to the weather station.

[0027] The first preset range of a weather station can be understood as the observation area. Each weather station has a corresponding observation area, and the types of observation areas include visibility observation areas, meteorological element observation areas, and non-visibility observation areas. In other words, the type of observation area corresponding to a weather station can be determined based on the type of observation data collected by the weather station within the first preset range.

[0028] Step S106 : Determine the visibility selection index for the areas with visibility observation and the areas without visibility observation according to the sum of the proportion of the visibility compliance time in each type of administrative district.

[0029] Here, for the two types of observation areas, namely, areas with visibility observation and areas without visibility observation, the visibility selection indexes of these two types can be determined based on the proportion of time that the visibility data of each type of administrative district in the observation area meets the requirements.

[0030] Step S108: determining the visibility selection index of the meteorological element observation area according to the proportion of time periods that meet the preset meteorological standards in each type of administrative district during the historical period.

[0031] Here, for meteorological element observation areas, the selection index of this type of observation area is determined based on the proportion of time that the meteorological data in each type of administrative area meets the preset meteorological standards; among which the preset meteorological standards include relative humidity, wind speed and temperature.

[0032] Step S110 , based on the risk level corresponding to the visibility selection index, the geographical conditions of each observation area and the construction requirements, assist in planning the construction route in the area to be constructed.

[0033] Here, the risk level corresponding to the visibility selection index is used together with the geographical conditions and construction needs of each observation area as planning decision factors for the construction route.

[0034] In a preferred embodiment of actual application, based on the observation data collected by meteorological stations in the area to be planned for construction, the observation area type of each meteorological station within the first preset range can be known, and then according to the visibility / meteorological standards of each observation area type and each administrative district where the observation area is located, the duration for which the visibility / meteorological elements meet the requirements is determined, and then the visibility selection index of each type of observation area is calculated; finally, based on the risk level corresponding to the selection index and the geographical conditions and construction needs of the observation area, the construction route is assisted in planning. This method takes into account the actual application impact of visibility on road construction and can ensure the reliability of road construction decisions.

[0035] In some embodiments, the corresponding relationship of each area to be constructed may be obtained from a third-party platform, database, etc.; illustratively, step S102 includes: Step 1.1: Obtain from a third-party platform the types of administrative districts included in the area to be constructed, the number of weather stations, the latitude and longitude coordinates of each weather station, and the observation data and data type of each weather station.

[0036] Here, based on the geographical scope of the area to be constructed, the number and types of administrative districts included in the area to be constructed, the number and coordinates of weather stations, and the type of observation data that each weather station can collect can be obtained from third-party geographic websites.

[0037] On the basis of the above embodiment, based on the type of observation data collected by each weather station, the type of observation area corresponding to each weather station is determined, specifically including: Step 2.1: Obtain the data type of the observation data collected within a first preset range corresponding to each weather station.

[0038] Among them, the first preset range can be selected from 2KM, 3KM, 5KM, etc.; the data type of the observation data can include visibility observation data and meteorological observation data.

[0039] As an optional embodiment, the first preset ranges corresponding to different weather stations and weather stations in different administrative districts may be different; for example, the first preset range of weather station 1 is 2KM, and the first preset range of weather station 2 is 3KM; for example, the first preset range of weather station 1 in administrative district A is 3KM, and the first preset range of weather station 1 in administrative district B is 2KM.

[0040] Step 2.2: Determine whether the data type contains visibility observation data or meteorological element observation data.

[0041] Here, the type of the observation area is determined based on whether the observation data collected by each weather station within the first preset range contains visibility observation data or meteorological element observation data.

[0042] Step 2.3: If visibility observation data exists, the first preset range corresponding to the weather station is determined as the visibility observation area.

[0043] If visibility observation data exists, the subsequent steps may evaluate the visibility level of the observation area based on the visibility observation data.

[0044] Step 2.4: If only meteorological element observation data exists, the first preset range corresponding to the meteorological station is determined as the meteorological element observation area.

[0045] Among them, if there is no visibility observation data but there is meteorological element observation data, the subsequent steps can estimate the visibility level of the observation area based on the meteorological observation data.

[0046] Step 2.5: If there is no visibility observation data and meteorological element observation data, the first preset range corresponding to the meteorological station is determined as a non-visibility observation area.

[0047] If there is no visibility observation data, the subsequent steps may estimate the visibility level of the observation area based on the visibility observation data collected by the satellite.

[0048] In practical applications, for the visibility observation area and the non-visibility observation area, step S106 can calculate the visibility selection index through the following steps, specifically including: Step 3.1: Based on the visibility assessment standards corresponding to each type of administrative district, the visibility observation data collected by the meteorological station for the visibility observation area is evaluated to determine the occurrence duration of each visibility level in the preset historical time range.

[0049] Here, the visibility observation area belongs to at least one administrative district, and the visibility assessment standard corresponding to the visibility observation area is determined based on the type of each administrative district; each type of administrative district (northeast, southwest, etc.) may correspond to different visibility assessment standards; if the visibility observation area spans multiple administrative districts of different types, the visibility level of the visibility observation data collected in the visibility observation area and the frequency and duration of each visibility level are evaluated based on the various judgment standards of each administrative district type.

[0050] Step 3.2: Based on the proportion of the sum of the durations of each visibility level in the preset historical time range, determine the visibility selection index for the visibility observation area. This is specifically achieved through the following formula:

[0051] in, iRepresents low visibility level (Level 1 means visibility is less than 2000m; Level 2 means visibility is less than 1000m; Level 3 means visibility is less than 500m; Level 4 means visibility is less than 200m); is the frequency of occurrence of visibility level i (hours / year), and t is the number of hours corresponding to the preset historical time range; the numerator here is used to represent the sum of the occurrence durations of each visibility level, and the denominator is the number of hours corresponding to the preset historical time range, which can be 1 year, 2 years, 3 years, etc.; if the preset historical time range is 1 year, then t=8760.

[0052] or, In step 3.3, according to the visibility assessment standard corresponding to each type of administrative area, the visibility observation data collected by the satellite for the area without visibility observation is evaluated to determine the occurrence duration of each visibility level in the preset historical time range.

[0053] Here, the meteorological station in the no-visibility observation area can neither collect visibility observation data nor meteorological observation data, so the selection index of the observation area can be evaluated based on the visibility observation data collected by the satellite for the observation area; each no-visibility observation area belongs to at least one administrative district, and the visibility assessment standard corresponding to the no-visibility observation area is determined based on the type of each administrative district; similar to the above embodiment, each type of administrative district may correspond to different visibility assessment standards; if the no-visibility observation area spans multiple administrative districts of different types, the visibility level of the visibility observation data collected by the satellite from the no-visibility observation area and the frequency and duration of each visibility level are evaluated according to the judgment standard corresponding to each administrative district type.

[0054] Step 3.4: Determine the visibility selection index for the area without visibility observation based on the proportion of the sum of the duration of each visibility level in the preset historical time range. This is specifically achieved through the following formula:

[0055] in, i Represents low visibility level (Level 1 means visibility is less than 2000m; Level 2 means visibility is less than 1000m; Level 3 means visibility is less than 500m; Level 4 means visibility is less than 200m); is the frequency of occurrence of visibility level i (hours / year), and t is the number of hours corresponding to the preset historical time range; the numerator here is used to represent the sum of the occurrence durations of each visibility level, and the denominator is the number of hours corresponding to the preset historical time range, which can be 1 year, 2 years, 3 years, etc.; if the preset historical time range is 1 year, then t=8760.

[0056] As an optional embodiment, to ensure the accuracy of the assessment of the non-visibility observation area, before step 3.3, the method of the embodiment of the present invention further includes: Step 4.1, based on the visibility observation data sent by the meteorological station in the visibility observation area within the second preset range and received by the meteorological station in the non-visibility observation area, correct the visibility observation data collected by the satellite.

[0057] It should be noted that if a visibility observation area or a meteorological element observation area exists near a non-visibility observation area, the visibility observation data collected by the satellite for the non-visibility observation area can be corrected based on the visibility observation data collected by the meteorological station in the visibility observation area or the meteorological element observation data collected by the meteorological station in the meteorological element observation area to ensure the accuracy of the visibility observation data collected by the satellite. The second preset range is larger than the first preset range and can be selected from 5km, 10km, etc.

[0058] On this basis, for the meteorological element observation area, step S108 can calculate the visibility selection index through the following steps, specifically including: Step 5.1: Evaluate the meteorological element observation data collected by the meteorological station for the meteorological element observation area based on the preset meteorological standards corresponding to each type of administrative district, and determine the duration of low visibility during the historical period. Each meteorological element observation area belongs to at least one administrative district, and the preset meteorological standards corresponding to the meteorological element observation area are determined based on the type of administrative district. Similar to the previous embodiment, the preset meteorological standards for different types of administrative districts are different, as shown in Table 1 below: Table 1 Range of high-frequency low-visibility conditions in each study area

[0059] Among them, the duration of meeting the preset meteorological standards is used as the duration of low visibility; that is, when the administrative area, relative humidity, wind speed and temperature in Table 1 are simultaneously met, the low visibility that meets the preset meteorological standards is determined; the historical period is pre-set and can generally be set according to actual conditions. The embodiment of the present invention takes a historical period of 10 years as an example for explanation. As shown in Table 1, the duration of low visibility in the past 10 years can be determined.

[0060] Step 5.2: Calculate the proportion of low visibility duration in the historical period and determine the average value used to represent the total number of low visibility hours in a year. The specific formula is as follows:

[0061] in, It is the average of the total number of hours of low visibility in the weather station's historical period, such as the past 10 years. It is the total number of hours in a year when the relative humidity, wind speed and temperature at the weather station simultaneously meet the prone conditions, that is, the prone hours of low visibility / the duration of low visibility.

[0062] Step 5.3: If the average value is greater than or equal to the preset low visibility duration, determine the visibility selection index for the meteorological element observation area based on a first fitting relationship. The fitting relationship is a curve that is determined in advance using visibility observation data and meteorological element observation data collected by meteorological stations in a preset administrative area during a historical period, and is used to represent the relationship between the visibility selection index and the average value of the total number of hours of low visibility prone years during the historical period. This fitting relationship is divided, based on the preset low visibility duration, into a first fitting relationship when the average value is greater than or equal to the preset low visibility duration, and a second fitting relationship when the average value is less than the preset low visibility duration. It should be noted that the preset administrative region can be understood as all administrative regions in the country, or the administrative region to which the current meteorological element observation area belongs; as an optional embodiment, the meteorological element observation area is based on the target administrative region to which it belongs, and selects the first fitting relationship and the second fitting relationship fitted by the visibility observation data and meteorological element observation data collected by the meteorological station in the target administrative region during the historical period to realize the determination of the visibility selection index of the meteorological element observation area.

[0063] Here, the preset low visibility duration may be 500 hours. If the average value calculated in the above embodiment is greater than or equal to the preset low visibility duration, the visibility selection index of the meteorological element observation area may be calculated using the following formula:

[0064] Among them, I is the visibility selection index.

[0065] In step 5.4, if the average value is less than the preset low visibility duration, the second fitting relationship is used to determine the visibility selection index of the meteorological element observation area. Specifically, the visibility selection index of the meteorological element observation area can be calculated using the following formula:

[0066] Among them, I is the visibility selection index.

[0067] In some embodiments, based on the visibility selection index calculated in the above embodiments, auxiliary planning of construction routes can be implemented according to S110, specifically including: Step 6.1: If the visibility selection index corresponds to a low risk level, then based on the geographical conditions and construction needs of each low risk level observation area, control each low risk level observation area to participate in the planning of the construction route in the area to be constructed.

[0068] If I<3.0, the observation area belongs to the low-risk (I) level and the visibility is relatively good. At this time, the geographical conditions and construction needs of the observation area can be combined to make planning decisions on the construction routes in the area to be constructed.

[0069] In step 6.2, if the visibility selection index corresponds to a medium risk level and the visibility is relatively average, then based on the geographical conditions and construction needs of each medium risk level observation area, it is again determined whether to control each medium risk level observation area to participate in the planning of the construction route in the area to be constructed.

[0070] If 5.0>I≥3.0, the observation area belongs to the medium risk (II) level; at this time, further judgment is made based on the visibility / low visibility risk forecast system, and then based on the risk satisfaction results combined with the geographical conditions and construction needs of the observation area, planning decisions on construction routes in the area to be constructed are made.

[0071] Step 6.3: If the risk level corresponding to the visibility selection index of the observation area is high risk, control the planning and installation of traffic safety guidance devices in the observation area.

[0072] If I ≥ 5.0, the observation area belongs to the high-risk (III) level and the visibility is relatively poor. At this time, visibility observation equipment, visibility / low visibility risk forecasting systems or traffic safety induction devices can be added, and the observation area cannot be selected for construction route planning.

[0073] The embodiment of the present invention makes full use of the measured data of existing meteorological stations. According to the distribution of meteorological stations along the highway, it determines three types of areas: areas with visibility observation, areas without visibility observation but with basic element observation areas of conventional meteorological stations, and areas with neither visibility observation nor basic element observation areas of conventional meteorological stations. Each observation area calculates its own visibility selection index, which can realize the evaluation of the low visibility level at any point / road section across the country; at the same time, the low visibility selection level is determined according to the size of the index, and it assists in road construction route planning or recommends the layout location of low visibility driving safety intelligent guidance.

[0074] In some embodiments, as Figure 2 As shown, an embodiment of the present invention provides a device for assisting in planning a construction route based on visibility, comprising: The acquisition module obtains the observation data collected by each meteorological station in the area to be constructed and the type of each administrative district; a division module, based on the data type of the observation data within the first preset range corresponding to the weather station, dividing the observation area where each weather station is located; wherein the observation area includes a visibility observation area, a meteorological element observation area, and a non-visibility observation area; The first determination module determines the visibility selection index of the visibility observation area and the visibility non-observation area based on the sum of the proportion of the visibility standard duration in each type of administrative area; The second determination module determines the visibility selection index for the meteorological element observation area based on the proportion of time that each type of administrative area meets preset meteorological standards during the historical period; wherein the preset meteorological standards include relative humidity, wind speed and temperature; The planning module assists in planning the construction route in the area to be constructed based on the risk level corresponding to the visibility selection index, the geographical conditions and construction needs of each observation area.

[0075] Furthermore, the first determination module is specifically used to determine the occurrence duration of each visibility level in a preset historical time range based on the visibility observation data collected by the standard assessment meteorological station corresponding to each type of administrative district in the visibility observation area for the visibility observation area; determine the visibility selection index of the visibility observation area based on the proportion of the sum of the occurrence durations of the visibility levels in the preset historical time range; or determine the occurrence duration of each visibility level in a preset historical time range based on the visibility observation data collected by the standard assessment satellite corresponding to each type of administrative district in the non-visibility observation area for the non-visibility observation area; determine the visibility selection index of the non-visibility observation area based on the proportion of the sum of the occurrence durations of the visibility levels in the preset historical time range.

[0076] Furthermore, before the step of determining the occurrence duration of each visibility level in a preset historical time range by evaluating the visibility observation data collected by the satellite for the area without visibility observation according to the standard corresponding to each type of administrative district in the area without visibility observation, the device is also used to correct the visibility observation data collected by the satellite based on the visibility observation data sent by the meteorological station in the area with visibility observation within a second preset range received by the meteorological station in the area without visibility observation; wherein the second preset range is larger than the first preset range.

[0077] Furthermore, the first determination module is specifically used to evaluate the meteorological element observation data collected by the meteorological station for the meteorological element observation area according to the preset meteorological standards corresponding to each type of administrative district in the meteorological element observation area, and determine the duration of low visibility in the historical period; wherein, the duration that meets the preset meteorological standards is used as the duration of low visibility; calculate the proportion of the duration of low visibility in the historical period, and determine the average value for characterizing the total number of hours in a year prone to low visibility; if the average value is greater than or equal to the preset low visibility duration, the visibility selection index of the meteorological element observation area is determined by a first fitting relationship; if the average value is less than the preset low visibility duration, the visibility selection index of the meteorological element observation area is determined by a second fitting relationship; wherein, the fitting relationship is a curve determined by the visibility observation data and meteorological element observation data collected by the meteorological station in the preset administrative district in the historical period, which is used to characterize the relationship between the visibility selection index and the average value in the historical period; the fitting relationship includes the first fitting relationship and the second fitting relationship.

[0078] Furthermore, the planning module is specifically used to, if the visibility selection index corresponds to a low risk level, control each observation area of the low risk level to participate in the planning of the construction route in the area to be constructed based on the geographical conditions and construction needs of each observation area of the low risk level; if the visibility selection index corresponds to a medium risk level, then based on the geographical conditions and construction needs of each observation area of the medium risk level, again determine whether to control each observation area of the medium risk level to participate in the planning of the construction route in the area to be constructed.
