Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cable passage external damage prevention, and particularly relates to a road surface environment early warning method and system. BACKGROUND

[0002] With the development of urban construction, the cable ratio of regional distribution network is continuously improved, a large number of excavation construction operations such as road reconstruction and municipal engineering construction are carried out, and cable external damage accidents occur frequently, which causes the public distribution network line to trip, seriously endangers the safety of the power grid, affects the orderly life of all sectors of society, and causes great economic losses.

[0003] In the past, warning stakes are buried above the cable passage to warn the surrounding area and avoid excavation construction. In maintenance and construction, the positions of adjacent warning stakes are far apart, especially many facility maintenance and construction projects are carried out at night, which increases the difficulty of identifying warning stakes, and it is easy to cause the cable to be accidentally damaged during excavation due to position judgment error in the construction process.

[0004] A cable damage prevention online monitoring warning system is disclosed in Chinese Patent No. CN114783320A, which comprises a stand column arranged on the ground on one side of the laid cable, a gateway arranged on the stand column, a warning board provided with a backlight source, a control module, an image monitoring module, a GPS module and a power supply module, the backlight source, the control module, the image monitoring module and the GPS module are coupled with the gateway, and the gateway is connected with the background through a cloud server; a plurality of cover plates are arranged above the laid cable in sequence along the direction of the laid cable, and the cover plates are connected with the control module to form a loop through the metal induction line arranged therebetween, when the cover plates are damaged and the loop is disconnected, the control module and the gateway can send an alarm, on-site images and position information to the background. It can be seen that the system has the following problems: the system has high cost, and the control system needs to push the cable damage to the patrol personnel for timely on-site confirmation, which may cause the cable to be accidentally damaged during construction excavation due to untimely monitoring and judgment.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0058] In addition, in the description of the present application, "a plurality of" means two or more, unless otherwise specified.

[0059] In the past, warning stakes will be buried above the cable channel to warn the surrounding and avoid excavation construction. In maintenance and construction, the positions of adjacent warning stakes are far apart, especially many facility maintenance and construction projects are carried out at night, which increases the difficulty of identifying warning stakes, and it is easy to cause the cable to be damaged accidentally during excavation due to incorrect position judgment.

[0060] In combination with the prior art, the ground on one side of the cable laying is provided with a stand, a gateway is arranged on the stand, a warning sign with a backlight source, a control module, an image monitoring module, a GPS module and a power supply module are arranged, the backlight source, the control module, the image monitoring module and the GPS module are coupled with the gateway, and the gateway is connected with the background through a cloud server; a plurality of cover plates are sequentially arranged above the cable laying in the direction of the cable laying, the cover plates are connected with the control module through the metal induction lines arranged therebetween to form a loop, when the cover plates are damaged to break the loop, the control module and the gateway can send an alarm, on-site images and location information to the background. The problem of cable warning is solved. However, based on the above scheme, the system cost is high, and the control system needs to push the patrol personnel to confirm the site in time when the cable is damaged by external force, which may cause the cable to be damaged accidentally during construction excavation due to the delay of monitoring and judgment.

[0061] Therefore, the technical problem actually solved by the present application is how to improve the accuracy of road surface environment early warning under the premise of maintaining the cost.

[0062] Firstly, based on the cognition difference of the road surface environment in the prior art, the factors affecting the cable ground road surface environment include road construction, road driving and weather, based on the content disclosed in the background art, if the road construction, that is, the direct destruction of the road, can be perceived when the cover plate is damaged, and then an alarm and on-site images or location information are sent through the gateway or communication device; if the road driving or weather factor cannot directly damage the cover plate, it cannot be detected, and additional monitoring methods such as patrol personnel or on-site confirmation methods need to be added, however, road driving and weather factors are difficult to predict in the disclosed scheme of the background art, thus, the proportion of false alarms is large.

[0063] Therefore, in view of the above situation, the above describes three factors, that is, the road construction, road driving and weather conditions.

[0064] For road construction, it can be understood as the destruction of the road, and the destruction of the road will cause vibration, and the nails or warning columns set at the same time will also vibrate synchronously;

[0065] For road driving, the road will also show a vibration state during the process of vehicle passing through the road;

[0066] For weather, the road will also show a vibration state when the rain hits the road;

[0067] The common characteristics of road construction, road driving and weather are vibration, and the parameters related to vibration are amplitude, vibration frequency, amplitude-position curve, amplitude difference, etc.

[0068] Based on this, as Figure 1 shown, a road surface environment monitoring system is provided, comprising:

[0069] The acquisition module 10 is configured to acquire the road surface vibration information based on the stud and the subgrade vibration information based on the warning column;

[0070] The judgment module 20 is connected with the acquisition module 10 and is configured to obtain the vibration evaluation value of a single stud, the vibration evaluation value of a single warning column, the amplitude-stud position information, and the warning column amplitude difference value information according to the road surface vibration information and the subgrade vibration information acquired by the acquisition module 10; determine the state of the single stud and the state of the single warning column according to the vibration evaluation value of the single stud and the vibration evaluation value of the single warning column according to the set evaluation standard; obtain the road state information according to the proportion of the studs in different states and the warning columns in different states in the total number of studs and the total number of warning columns respectively; and determine the road surface judgment result according to the amplitude-stud position information and the warning column amplitude difference value information after obtaining the road state information.

[0071] The adjustment module 30 is connected with the judgment module 20 and is configured to adjust the warning parameters of each stud and each warning column according to the road surface judgment result.

[0072] According to the understanding of the present scheme, in the present scheme, the state of the road surface is classified and quantized in multiple levels, specifically:

[0073] The first-level processing classification of the state of the road surface includes: determining the state of the single stud and the state of the single warning column according to the vibration evaluation value of the single stud and the vibration evaluation value of the single warning column according to the set evaluation standard; and obtaining the road state information according to the proportion of the studs in different states and the warning columns in different states in the total number of studs and the total number of warning columns respectively.

[0074] The second-level processing classification of the state of the road surface includes: determining the road surface judgment result according to the amplitude-stud position information and the warning column amplitude difference value information after obtaining the road state information.

[0075] Thus, the state of the road surface is refined and split, thereby facilitating the states of the regional road surface, and the same type of monitoring parameter is used to participate in the judgment condition for the state subdivision of the road surface, which is beneficial to simplify the system / structure in system application.

[0076] In addition, by calculating the vibration evaluation values ​​of a single road spike and a single warning post using the collected roadbed vibration information and road surface vibration information, the state of a single road spike and a single warning post is initially determined. The current road surface state is initially determined based on the proportion of road spikes and warning posts in different states. Furthermore, a judgment module is used to determine the judgment method for abnormal road surface environment based on the distribution of the amplitude-road spike position curve and the amplitude difference. Based on the judgment results, the warning parameters of each road spike and each warning post are adjusted to the corresponding values, so that each judgment condition is quantified, which is conducive to intuitively obtaining the judgment results and improving the timeliness of monitoring.

[0077] The following will illustrate this with specific examples, such as... Figure 2 As shown, road stud 1 is placed on the road surface, warning post 2 is placed beside the road, and cable 3 is placed near the road stud and warning post. In this embodiment, road stud 1 is used to monitor / indicate the condition of the road surface, and warning post 2 is used to monitor / indicate the condition of the roadbed.

[0078] This solution combines data monitored by road spikes and warning posts to comprehensively determine the road surface condition, thereby improving the accuracy of the judgment results.

[0079] Specifically, such as Figure 3 As shown, the judgment module 20 includes:

[0080] The first judgment unit 201 is used to obtain the vibration evaluation value of a single road stud based on the road vibration information collected by the acquisition module 10 and to obtain the vibration evaluation value of a single warning post based on the roadbed vibration information collected by the acquisition module 10.

[0081] When the vibration evaluation value calculated on the current road spike is greater than the set road spike vibration evaluation value, the current road spike is determined to be in a first-level state; when the vibration evaluation value calculated on the current road spike is less than or equal to the set road spike vibration evaluation value, the current road spike is determined to be in a second-level state.

[0082] When the vibration evaluation value calculated for the current warning post is greater than the set vibration evaluation value for the warning post, the current road stud is determined to be in Class I state; when the vibration evaluation value calculated for the current warning post is less than or equal to the set vibration evaluation value for the warning post, the current warning post is determined to be in Class II state.

[0083] Among them, the set vibration evaluation values ​​for road spikes and warning posts are empirical values ​​obtained through multiple test trials.

[0084] And the vibration evaluation value of the single stud, the vibration evaluation value of the single warning column, the amplitude-stud position information and the warning column amplitude difference information are obtained based on the road surface vibration information and the roadbed vibration information collected by the collection module 10, which is beneficial to quantitatively calculate the state of the road surface and facilitate condition judgment.

[0085] Therefore, the definition formula is defined, and specifically, the acquisition mode of the vibration evaluation value of the single stud satisfies β is the stud evaluation coefficient, a1 is the stud amplitude data contained in the road surface vibration information, b1 is the stud vibration frequency data contained in the road surface vibration information, and t1 is the stud vibration time length data contained in the road surface vibration information;

[0086] The acquisition mode of the vibration evaluation value of the single warning column satisfies γ is the warning column evaluation coefficient, a2 is the warning column amplitude data contained in the roadbed vibration information, b2 is the warning column vibration frequency data contained in the roadbed vibration information, and t2 is the warning column vibration time length data contained in the roadbed vibration information.

[0087] The purpose is to obtain two quantifiable parameters based on the amplitude collected by the second vibration sensor, the vibration frequency collected by the second vibration sensor and the vibration time length collected by the second vibration sensor, which is beneficial to condition judgment.

[0088] Specifically, the evaluation coefficient γ is used to make the value of the quantifiable parameter obtained in a range area conducive to judgment, for example, the vibration evaluation value of the stud is in the value range of 1-100.

[0089] An exemplary example is used to illustrate as follows:

[0090] Taking a road section with a preset length of 100 m as an example, 10 studs and 10 warning columns are arranged at equal intervals on the road section, and at a certain moment, the parameters of the stud vibration evaluation value D monitored by the above-mentioned 10 studs and the warning column vibration evaluation value J monitored by the 10 warning columns are shown in Table 1:

[0091] Table 1

[0092]

[0093]

[0094] Combined with the set stud vibration evaluation value 8.50 and the set stud evaluation value 12.50, according to the monitoring results, the states of the single stud and the single warning column are shown in Table 2:

[0095] Table 2

[0096]

[0097] In this embodiment, asFigure 3 As shown, the judging module 20 further comprises:

[0098] The second judging unit 202 is configured to obtain road state information according to the proportion of the different state of the studs and the different state of the warning columns in the total number of the studs and the total number of the warning columns.

[0099] When the proportion of the studs in the first state in the total number of the studs is greater than the set stud preset proportion and the proportion of the warning columns in the first state in the total number of the warning columns is greater than the set warning column preset proportion, it is determined that the road surface environment is in a first abnormal state.

[0100] When the proportion of the studs in the first state in the total number of the studs is greater than the set stud preset proportion and the proportion of the warning columns in the first state in the total number of the warning columns is less than or equal to the set warning column preset proportion, it is determined that the road surface environment is in a second abnormal state.

[0101] When the proportion of the studs in the first state in the total number of the studs is less than or equal to the set stud preset proportion and the proportion of the warning columns in the first state in the total number of the warning columns is greater than the set warning column preset proportion, it is determined that the road surface environment is in a third abnormal state.

[0102] When the proportion of the studs in the first state in the total number of the studs is less than or equal to the set stud preset proportion and the proportion of the warning columns in the first state in the total number of the warning columns is less than or equal to the set warning column preset proportion, it is determined that the road surface environment is in a normal state.

[0103] First of all, it needs to be understood that the set stud preset proportion and the set warning column preset proportion are included in the second judging unit 202, and the purpose is to set rules to plan the state of the road surface into four categories in combination with the studs in the first state or the second state and the warning columns in the first state or the second state.

[0104] First of all, the condition of the normal state is defined, that is, the proportion of the studs in the first state in the total number of the studs is less than or equal to the set stud preset proportion and the proportion of the warning columns in the first state in the total number of the warning columns is less than or equal to the set warning column preset proportion.

[0105] The condition of the absolute abnormality of the road is defined, that is, when the proportion of the studs in the first state in the total number of the studs is greater than the set stud preset proportion and the proportion of the warning columns in the first state in the total number of the warning columns is greater than the set warning column preset proportion, it is determined that the road surface environment is in a first abnormal state, which indicates that construction occurs around the road surface.

[0106] In addition, the second abnormal state and the third abnormal state refined can be used to refer to the abnormality of the road surface caused by the oncoming vehicle or the abnormality of the road surface caused by the weather.

[0107] Since the second abnormal state and the third abnormal state can represent that construction occurs on the road surface / surroundings or that weather causes driving abnormality.

[0108] As an example, in combination with Table 2 described above, the states of the studs and the warning columns in Table 2 are counted, the proportion of the studs in the first level state is 60%, and the proportion of the warning columns in the first level state is 70%, the proportion of the studs in the first level state is greater than the first level preset proportion 50% set in the determination module, and the proportion of the warning columns in the first level state is greater than the first level preset proportion 50% set in the determination module, that is, it is determined that construction occurs on the road surface / surroundings.

[0109] The vibration evaluation value of the stud is combined and compared with the vibration evaluation value of the warning column, which indicates that the road is determined based on the states of each stud and each warning column. Since the judgment condition is relatively single, the state of the road surface / surroundings cannot be refined,

[0110] Therefore, based on the above, the judgment conditions of the second abnormal state and the third abnormal state are distinguished. For the road surface / surroundings construction and weather causes driving abnormality in the second abnormal state, the amplitude-stud position information condition is added to further distinguish them. Similarly, for the road surface / surroundings construction and weather causes driving abnormality in the third abnormal state, the warning column amplitude difference information condition is added to further distinguish them. Specifically, the determination module 20 further comprises:

[0111] A third determination unit 203, which is configured to determine the road surface determination result by combining the amplitude-stud position information when the road state information indicates that the road surface environment is in the second abnormal state, and determine the road surface determination result by combining the warning column amplitude difference information when the road state information indicates that the road surface environment is in the third abnormal state.

[0112] When the amplitude-stud position curve indicated in the amplitude-stud position information is normally distributed or when the current warning column amplitude difference indicated in the warning column amplitude difference information is greater than the preset amplitude difference, it is determined that the road surface environment is the first determination result. As an example, the first determination result indicates that construction occurs on the road surface / surroundings.

[0113] When the amplitude-stud position curve indicated in the amplitude-stud position information is uniformly distributed or when the current warning column amplitude difference indicated in the warning column amplitude difference information is less than or equal to the preset warning column amplitude difference, it is determined that the road surface environment is the second determination result. As an example, the second determination result indicates that weather causes driving abnormality.

[0114] Therefore, the determination result of the road surface environment in the present scheme is as follows: Figure 3Display.

[0115] After the result judgment is met, how to adjust the indicating state of the stud and the warning column, such as Figure 3 In combination Figure 4 As shown, the judgment module 20 further comprises:

[0116] The fourth judgment unit 204 is configured to, when the road surface environment is the first judgment result, obtain a construction grade evaluation value according to the amplitudes of the single stud and the single warning column contained in the road surface vibration information and the roadbed vibration information collected by the collection module 10.

[0117] When it is judged that the current construction grade evaluation value is less than the first preset construction grade evaluation value, the first construction state information is outputted.

[0118] When it is judged that the current construction grade evaluation value is greater than or equal to the first preset construction grade evaluation value and less than the second preset construction grade evaluation value, the second construction state information is outputted.

[0119] When it is judged that the current construction grade evaluation value is greater than or equal to the second preset construction grade evaluation value, the third construction state information is outputted.

[0120] The first preset construction grade evaluation value and the second preset construction grade evaluation value are experience values after multiple tests. If only the first preset construction grade evaluation value is set, the construction state information outputted is only two kinds, which can only meet the output of the construction state of yes / no and cannot meet the judgment of the construction degree on site.

[0121] Therefore, in combination with the first adjustment unit 301 in the adjustment module 30, the first adjustment unit 301 is configured to adjust the operating parameters of the warning column and the stud according to the received first construction state information, the second construction state information and the third construction state information.

[0122] The first adjustment unit 301 controls to close each stud and turn on each warning column to the constant light mode when the first construction state information outputted by the fourth judgment unit 204 is received.

[0123] The first adjustment unit 301 controls each stud to the constant light mode and turns on each warning column to the flashing mode when the second construction state information outputted by the fourth judgment unit 204 is received.

[0124] The first adjustment unit 301 controls each stud to the constant light mode and turns on each warning column to the flashing mode at a set frequency when the third construction state information outputted by the fourth judgment unit 204 is received.

[0125] This indicates the construction intensity of the road surface environment.
