[0042] Please refer to Figure 1 , Figure 1 is a schematic diagram of an application environment provided by an embodiment of the present application, as Figure 1 indicated, the application environment includes a roadside module 01, a cloud 02, and a target terminal 03.

[0043] Specifically, the roadside module 01 can include a plurality of roadside ends, each of which can be a road end mobile edge computing platform, and each of which can include a roadside sensor, a network communication unit, a processor, a memory, and the like. Specifically, taking a roadside end 04 in the plurality of roadside ends as an example, the roadside end 04 can be configured to obtain position offset data of a plurality of manhole covers in a second target area, the second target area being an area in the first target area corresponding to the roadside end 04; send the position offset data to the cloud 02; receive rainfall data of the first target area sent by the cloud 02; and in the case that the rainfall data meets a preset warning condition, push rainfall warning information to the target terminal 03 in the second target area.

[0044] Specifically, the cloud 02 can be a regional service platform terminal of the first target area, for example, the regional service platform terminal can include a manhole cover management platform terminal, and the cloud 02 can include a network communication unit, a processor, a memory, and the like. Specifically, the cloud 02 can be configured to receive position offset data of a plurality of manhole covers sent by a plurality of roadside ends in the roadside module 01 in the first target area; in the case that it rains in the first target area, perform rainfall analysis based on the position offset data to obtain rainfall data of the first target area; and send the rainfall data to the plurality of roadside ends respectively.

[0045] Specifically, the target terminal 03 can include an entity device such as a smart phone, a computer (such as a desktop computer, a tablet computer, a notebook computer), a digital assistant, a smart voice interaction device (such as a smart speaker), a smart wearable device, a vehicle terminal, and the like, and can also include a software such as a computer program, an applet, and the like running in the entity device. Specifically, the target terminal 03 can be configured to receive the rainfall warning information pushed by the roadside end 04 in the case that the rainfall data meets a preset warning condition.

[0046] In an optional embodiment, the application environment can further include a plurality of manhole cover ends of a plurality of manhole covers respectively, and each of the manhole cover ends can include a sensor, a network communication unit, a processor, a memory, and the like. Specifically, the manhole cover end can collect position offset data of the corresponding manhole cover and send the position offset data to the roadside end corresponding to the manhole cover end.

[0047] A method for pushing information provided by an embodiment of the present application is described below. Figure 2A flowchart of an information pushing method provided in an embodiment of the present application is shown. It should be noted that the present specification provides method operation steps as described in the embodiments or flowcharts, but more or fewer operation steps can be included based on conventional or non-creative labor. The order of steps listed in the embodiments is only one of the many execution orders, and does not represent the only execution order. In actual system or product execution, the method order shown in the embodiments or the drawings can be executed in sequence or in parallel (for example, in a parallel processor or multi-threaded processing environment). Specifically, as shown in Figure 2 The above method can include:

[0048] S201, the target road side terminal obtains position offset data of each manhole cover in the second target area, and the second target area is an area corresponding to the target road side terminal in the first target area, and the target road side terminal is any road side terminal in the first target area.

[0049] In the embodiments of the present specification, the first target area can be a preset geographical range with large traffic flow and large passenger flow. Specifically, the preset geographical range can be set according to actual needs. For example, the geographical range of a certain community, the geographical range of a certain street.

[0050] In the embodiments of the present specification, the first target area can include a plurality of sub-areas, and the second target area is a sub-area corresponding to the target road side terminal in the first target area. Specifically, the sub-area corresponding to the target road side terminal can be a preset radius area range that the target road side terminal can cover. Specifically, the preset radius can be set according to actual needs. For example, the preset radius can be 500 meters.

[0051] In the embodiments of the present specification, the road side terminal can be a road side unit (Road Side Unit). In actual application, the road side terminal is usually deployed at a road intersection.

[0052] In a specific embodiment, the communication module of the road side terminal can include but is not limited to: a PC5 direct communication interface, a cellular network communication interface (uu communication interface), and a fiber communication interface, etc.

[0053] In a specific embodiment, as shown in Figure 3 The above target road side terminal obtaining position offset data of each manhole cover in the second target area can include:

[0054] 1) The target road side terminal receives initial position data and real-time position data sent by each manhole cover in the second target area.

[0055] Specifically, the well lid end can be an intelligent terminal arranged on the well lid. The well lid end can include, but is not limited to, a positioning module, a communication module, a control module, a power supply module, and the like. Specifically, the positioning module can include a sensor, and the communication module can include a PC5 direct communication interface.

[0056] In a specific embodiment, the well lid end can broadcast well lid state information through its own PC5 direct communication interface, and the target road side end can receive the well lid state information broadcast by the well lid end within a preset radius range through its own PC5 direct communication interface.

[0057] Specifically, the well lid state information can include initial position data, real-time position data, well lid identification information, information sending time, and the like.

[0058] In a specific embodiment, when the positioning module of the well lid end confirms that the well lid has been displaced greatly, the control module of the well lid end can broadcast the well lid state information through the PC5 direct communication interface in the communication module.

[0059] 2) The target road side end performs position offset analysis based on the initial position data and the real-time position data to generate position offset data.

[0060] Specifically, the target road side end can obtain offset distance data of each well lid based on the initial position data and the real-time position data of each well lid, and take the offset distance data as the position offset data.

[0061] As can be seen from the above embodiments, the target road side end performs position offset analysis based on the initial position data and the real-time position data transmitted by the plurality of well lid ends to generate position offset data, which can improve the accuracy and real-time performance of the position offset data.

[0062] In an optional embodiment, after the target road side end obtains the position offset data of each well lid in the second target area, the above method can further include:

[0063] In a case where the position offset data of the target well lid meets a preset well lid offset condition, the target road side end pushes well lid offset alarm information for the target well lid to a first target terminal in the second target area, and the target well lid is any well lid in the plurality of well lids in the second target area.

[0064] Specifically, the preset well lid offset condition can be set in combination with the size information of the well lid in actual application.

[0065] In an optional embodiment, the offset risk analysis can also be performed according to the offset distance data of the manhole cover and the size information of the manhole cover to obtain a manhole cover offset risk index. In a case where the manhole cover offset risk index meets a preset manhole cover offset condition, the target roadside end pushes the manhole cover offset alarm information for the target manhole cover to the first target terminal in the second target area. The manhole cover offset risk index can represent the risk degree of the manhole cover offset.

[0066] In an example, in a case where the offset distance data is less than 1 / 8 of the diameter of the manhole cover, the manhole cover offset risk index can be a safe state, in a case where the offset distance data is between 1 / 8 of the diameter of the manhole cover and 1 / 4 of the diameter of the manhole cover, the manhole cover offset risk index can be a mild risk state, in a case where the offset distance data is between 1 / 4 of the diameter of the manhole cover and 1 / 2 of the diameter of the manhole cover, the manhole cover offset risk index can be a moderate risk state, and in a case where the offset distance data is greater than 1 / 2 of the diameter of the manhole cover, the manhole cover offset risk index can be a high risk state. Correspondingly, in a case where the manhole cover offset risk index is the mild risk state or the moderate risk state or the high risk state, the target roadside end pushes the manhole cover offset alarm information for the target manhole cover to the first target terminal in the second target area.

[0067] In the embodiments of the present disclosure, the first target terminal in the second target area can be a vehicle terminal corresponding to a passing vehicle, a mobile terminal corresponding to a passing pedestrian, and a terminal corresponding to a resident in the second target area.

[0068] Specifically, the manhole cover offset alarm information can include but is not limited to a manhole cover offset alarm short message, a mini-program push message, an APP push message, etc. The manhole cover offset alarm information can include the specific position of the offset manhole cover and the manhole cover offset risk index.

[0069] As can be seen from the above embodiments, the target roadside end pushes the manhole cover offset alarm information for the target manhole cover to the first target terminal in the second target area, which can improve the timeliness of the manhole cover offset alarm information push and avoid the safety hazards caused by the manhole cover offset.

[0070] S202, the target roadside end sends the position offset data to the cloud end.

[0071] In a specific embodiment, the target roadside end sends the manhole cover state information to the cloud end. Specifically, the manhole cover state information can include the position offset data, the manhole cover offset risk index, the manhole cover identification information, the information sending time, etc.

[0072] Specifically, the cloud end can perform deduplication processing on the manhole cover state information based on the manhole cover identification information and the information sending time to obtain a plurality of manhole cover state information corresponding to the plurality of manhole covers in the first area.

[0073] S203, in the case of rainfall in the first target area, the cloud analyzes rainfall based on the position offset data of the manhole covers sent by the plurality of roadside terminals, and obtains rainfall data of the first target area.

[0074] In an optional embodiment, as shown in Figure 3 The cloud analyzes rainfall based on the position offset data of the manhole covers sent by the plurality of roadside terminals, and obtains rainfall data of the first target area can include:

[0075] S301, the cloud analyzes the manhole cover offset based on the position offset data, and determines the manhole cover offset proportion data and the manhole cover average offset distance in the first target area.

[0076] Specifically, the manhole cover offset proportion data can represent the offset situation of the manhole cover in the first target area. For example, the manhole cover offset proportion data can include: manhole cover offset rate, specifically, manhole cover offset rate = 1 - manhole cover safety rate, manhole cover safety rate = number of manhole covers in the first target area whose offset danger index indicates a safe state / total number of manhole covers in the first target area.

[0077] Specifically, the manhole cover average offset distance = sum of offset distance data of each manhole cover in the first target area / total number of manhole covers.

[0078] S302, the cloud inputs the manhole cover offset proportion data and the manhole cover average offset distance into a rainfall prediction model to predict rainfall, and obtains rainfall data.

[0079] Specifically, the present inventors obtain a large amount of sample manhole cover offset proportion data, sample manhole cover average offset distance and sample rainfall data in a certain street on rainy days, and analyze the correlation of the above three kinds of data.

[0080] (1) First, use chart analysis method (line chart / scatter plot) to visualize the data.

[0081] (a) Use double-axis line chart, where the main axis is sample manhole cover offset proportion data and sample manhole cover average offset distance, and the secondary axis is sample rainfall data. The horizontal axis is the date of rainfall. Through the line chart, it can be found that the changes and trends of sample manhole cover offset proportion data, sample manhole cover average offset distance and sample rainfall data are roughly the same. From the regularity, the extreme values of sample manhole cover offset proportion data, sample manhole cover average offset distance and sample rainfall data appear on the same day. From the details, the short-term trend changes of sample manhole cover offset proportion data, sample manhole cover average offset distance and sample rainfall data are basically consistent.

[0082] (b) Using scatter plots, the time dimension is removed, and only the sample well lid offset ratio data and the sample rainfall data, the sample well lid offset ratio data and the sample rainfall data are focused on. We will take the sample well lid offset ratio data and the sample well lid average offset distance as the x horizontal coordinate, and the sample rainfall data as the y vertical coordinate. From the distribution of data points, it can be found that the independent variable x and the dependent variable y have the same trend, when the sample well lid offset ratio data and the sample well lid average offset distance increase, the sample rainfall data also increases.

[0083] (2) Then quantitatively judge the relationship between the sample well lid offset ratio data and the sample rainfall data, and the relationship between the sample well lid offset ratio data and the sample rainfall data.

[0084] (a) After calculating the covariance between the sample well lid offset ratio data, the sample well lid average offset distance and the sample rainfall data, the inventor gets a large positive value, so it can be explained that the relationship between the sample well lid offset ratio data and the sample rainfall data, and the relationship between the sample well lid offset ratio data and the sample rainfall data is positively correlated. The sample rainfall data increases with the increase of the sample well lid offset ratio data and the sample well lid average offset distance.

[0085] (b) The covariance and standard deviation of the sample well lid offset ratio data and the sample well lid average offset distance respectively with the sample rainfall data are calculated, and the correlation coefficient value is greater than 0 and very close to 1, which indicates that the two variables are positively correlated, and the two variables are highly correlated.

[0086] (3) On the basis of proving the correlation between the sample well lid offset ratio data, the sample well lid average offset distance and the sample rainfall data, the relationship between the sample well lid offset ratio data, the sample well lid average offset distance and the sample rainfall data is converted into a rainfall prediction model, and the future rainfall is predicted through the rainfall prediction model.

[0087] In a specific embodiment, the rainfall prediction model can be a multiple regression model. Specifically, an initial multiple regression model is created, the sample data (independent variable: sample well lid offset ratio data and sample well lid average offset distance, dependent variable: sample rainfall data) is imported into the model, and the predicted rainfall data corresponding to the sample well lid offset ratio data and the sample well lid average offset distance is calculated; the predicted rainfall data is compared with the sample rainfall data, so as to judge whether the multiple regression analysis result is accurate, and to improve the initial multiple regression model to obtain a target multiple regression model, and the target multiple regression model is used as the rainfall prediction model.

[0088] Therefore, the rain amount data obtained by inputting the cover offset proportion data and the cover average offset distance into the rain amount prediction model for rain amount prediction can include: inputting the cover offset proportion data and the cover average offset distance into a target multiple regression model for rain amount prediction to obtain rain amount data.

[0089] As can be seen from the above embodiments, inputting the cover offset proportion data and the cover average offset distance into the multiple regression model for rain amount prediction to obtain rain amount data can improve the accuracy of rain amount prediction in a small range.

[0090] In another optional embodiment, as shown in Figure 4 After the cloud performs cover offset analysis based on the location offset data to determine the cover offset proportion data and the cover average offset distance in the first target area, the method further includes:

[0091] S303, the cloud obtains preset proportion error data and preset distance error data.

[0092] In actual application, in addition to rain, other factors such as large vehicles also affect the cover offset, therefore, it is necessary to avoid the influence of large vehicles and other factors on the cover offset.

[0093] In a specific embodiment, the preset proportion error data and the preset distance error data can be obtained based on sample cover offset proportion data and sample cover average offset distance in non-rainy days.

[0094] Specifically, a large amount of sample cover offset proportion data and sample cover average offset distance in non-rainy days are obtained, and the preset proportion error data and the preset distance error data are calculated (the preset proportion error data = cumulative sum of sample cover offset proportion data in non-rainy days / sample quantity, and the preset distance error data = cumulative sum of sample cover average offset distance in non-rainy days / sample quantity).

[0095] S304, the cloud performs data correction on the cover offset proportion data based on the preset proportion error data to obtain offset proportion correction data.

[0096] Specifically, the cover offset proportion data is subtracted by the preset proportion error data to obtain the offset proportion correction data.

[0097] S305, the cloud performs data correction on the cover average offset distance based on the preset distance error data to obtain offset distance correction data.

[0098] Specifically, the cover average offset distance is subtracted by the preset distance error data to obtain the offset distance correction data.

[0099] In step S306, the cloud inputs the offset ratio correction data and the offset distance correction data into a rainfall prediction model to perform rainfall prediction and obtain rainfall data.

[0100] Specifically, the offset ratio correction data and the offset distance correction data are input into the target multiple regression model to perform rainfall prediction and obtain rainfall data.

[0101] As can be seen from the above embodiments, data correction is used to avoid the influence of other factors such as large vehicles on the deviation of the manhole cover, thereby improving the accuracy of rainfall prediction.

[0102] S204: The cloud sends rainfall data to the target roadside end.

[0103] S205: When the rainfall data meets the preset warning condition, the target roadside terminal pushes rainfall warning information to the first target terminal in the second target area.

[0104] Specifically, the rainfall warning information may include but is not limited to: rainfall warning text messages, mini-program push messages, APP push messages, etc. The rainfall warning information may include the specific location of the offset manhole cover.

[0105] In an optional embodiment, after performing rainfall analysis based on the position offset data in the cloud to obtain rainfall data for the first target area, the method may further include:

[0106] When the rainfall data meets the preset warning conditions, the cloud pushes rainfall warning information to the first target terminal in the first target area.

[0107] In the embodiment of the present specification, the first target terminal in the first target area may be a vehicle-mounted terminal corresponding to a passing vehicle, a mobile terminal corresponding to a passing pedestrian, or a terminal corresponding to a resident in the first target area.

[0108] It can be seen from the above embodiments that when the rainfall data meets the preset warning conditions, the target roadside end or the cloud pushes rainfall warning information to the first target terminal in the second target area, which can improve the pertinence and timeliness of the rainfall warning information push.

[0109] In a specific embodiment, Figure 5 As shown, after receiving, on the cloud side, the position offset data of the plurality of manhole covers sent by the plurality of roadside terminals in the first target area, the method may further include:

[0110] S206: The cloud performs maintenance priority analysis based on the position offset data to obtain maintenance priority data of the offset manhole covers among the multiple manhole covers.

[0111] Specifically, the cloud can set thresholds of the manhole cover safety rate, the manhole cover mild danger rate, the manhole cover moderate danger rate, and the manhole cover high danger rate corresponding to different rainfall data. The thresholds are obtained from experience values of cities in different periods, the same region, and the same rainfall, or from experience values of cities in the same period, different regions, and the same rainfall. Once the manhole cover safety rate is greatly different from the threshold, or the ratio between the manhole cover mild danger rate, the manhole cover moderate danger rate, and the manhole cover high danger rate is greatly different from the corresponding threshold in a certain period, it is determined that the manhole cover in the region has aging problems and needs comprehensive maintenance.

[0112] Specifically, the manhole cover safety rate = the number of manhole covers in the first target region with the safe state indicated by the manhole cover offset danger index / the total number of manhole covers in the first target region, the manhole cover mild danger rate = the number of manhole covers in the first target region with the mild danger state indicated by the manhole cover offset danger index / the total number of manhole covers in the first target region, the manhole cover moderate danger rate = the number of manhole covers in the first target region with the moderate danger state indicated by the manhole cover offset danger index / the total number of manhole covers in the first target region, and the manhole cover high danger rate = the number of manhole covers in the first target region with the high danger state indicated by the manhole cover offset danger index / the total number of manhole covers in the first target region.

[0113] In a specific embodiment, after the cloud receives the manhole cover state information, the maintenance priority of the manhole cover is determined according to the danger degree. Specifically, the maintenance priority of the manhole cover in the high danger state is the highest, the maintenance priority of the manhole cover in the moderate danger state is the second, and the maintenance priority of the manhole cover in the low danger state is the lowest.

[0114] S207, the cloud pushes the maintenance notification information of the offset manhole cover to the second target terminal based on the maintenance priority data.

[0115] Specifically, the second target terminal can be a mobile terminal corresponding to a maintenance personnel.

[0116] Specifically, the maintenance notification information can include but is not limited to: manhole cover maintenance notification short message, applet push message, APP push message, etc. The maintenance notification information can include the identification information, the specific position, the manhole cover offset danger index, the maintenance priority, and the maintenance task corresponding to the maintenance priority of the offset manhole cover.

[0117] In an optional embodiment, the cloud detects the manhole cover state in real time during the maintenance personnel going to and performing the maintenance task, and updates the priority of the manhole cover to be maintained and the maintenance task of the maintenance personnel according to the manhole cover identification. Specifically, the cloud first determines whether there is a newly added dangerous state manhole cover (including a light dangerous state manhole cover, a medium dangerous state manhole cover and a high dangerous state manhole cover); if there is no newly added dangerous manhole cover, it is determined whether there is a change in the dangerous state of the manhole cover; if there is no change in the dangerous state of the manhole cover, no new maintenance task is issued; if there is a change in the dangerous state of the manhole cover, it is determined whether there is an idle maintenance personnel; if there is an idle maintenance personnel, the maintenance task is issued to the idle maintenance personnel according to the maintenance priority, for example, two maintenance personnel are assigned to the high dangerous state manhole cover, and one maintenance personnel is assigned to the medium dangerous state manhole cover, if the number of idle maintenance personnel cannot meet the number requirement, the idle maintenance personnel is preferentially dispatched to the place with high maintenance priority; if there is no idle maintenance personnel, no new maintenance task is issued. In addition, if there is a newly added dangerous state manhole cover, the maintenance task is re-planned and issued to the maintenance personnel who has not started the maintenance operation (on the way to perform the task) and the idle maintenance personnel (if there is an idle maintenance personnel) according to the principle of maintenance priority, the shortest distance between the maintenance personnel and the manhole cover to be maintained, and the maintenance personnel who is performing the maintenance task continues to perform the current maintenance operation.

[0118] As can be seen from the above embodiments, the cloud analyzes the maintenance priority based on the position offset data, obtains the maintenance priority data of the offset manhole cover among the plurality of manhole covers, and pushes the maintenance notification information for the offset manhole cover to the terminal corresponding to the maintenance personnel based on the maintenance priority data, which can improve the timeliness and rationality of the maintenance task notification issuance.

[0119] As can be seen from the above embodiments of the present specification, the roadside end can collect the manhole cover offset data within a preset radius, by setting the roadside end at a plurality of intersections in the target area, the position offset data of each of the plurality of manhole covers in the first target area can be obtained, and the rainfall data of the target area can be obtained based on the position offset data, which improves the accuracy of rainfall prediction in a small range. In addition, in the case that the rainfall data meets the preset warning condition, the rainfall warning information can be pushed to the target terminal in the area corresponding to the roadside end through any roadside end, which improves the pertinence and timeliness of the rainfall warning push, and ensures the safety of people's travel. In addition, the roadside end, the target terminal and the manhole end can communicate through the PC5 direct communication interface. Since the V2X communication (PC5 direct communication) is not affected by the cellular mobile communication network, the SIM card traffic and the operator service condition, there is no need to worry about the problems of cellular mobile network communication quality, Internet of Things card traffic exhaustion and operator suspension of service. Based on the V2X communication between the roadside end and the target terminal, the target terminal corresponding motor vehicle, pedestrian and non-motor vehicle can be timely warned, and safety accidents caused by heavy rainfall and manhole displacement can be avoided.

[0146] 1) receive initial position data and real-time position data sent by each of a plurality of manhole cover ends in the second target area;

[0147] 2) perform position offset analysis based on the initial position data and the real-time position data to generate the position offset data.

[0148] The specific refinement steps of the embodiment of the information push method from the target road side end can be referred to the embodiment of the interactive side information push method, which will not be described here.

[0149] The embodiments of the present application also provide an information push system for implementing Figure 2 the method. The system embodiments correspond to the foregoing method embodiments and can implement all the contents of the foregoing method embodiments. For ease of reading, the system embodiments only briefly describe the contents of the foregoing method embodiments, and do not describe the details of the method embodiments one by one. As Figure 8 shown in the method, the system includes a target manhole cover end, a target road side end, a cloud end, and a first target terminal, wherein:

[0150] The target manhole cover end can be used to collect position offset data of the corresponding manhole cover and send the position offset data to a target road side end corresponding to the manhole cover end, wherein the target manhole cover end can be any manhole cover end of a plurality of manhole cover ends corresponding to the target road side end.

[0151] The target road side end can be used to obtain position offset data of a plurality of manhole covers in a second target area, wherein the second target area is an area corresponding to the target road side end in the first target area, and the target road side end is any road side end of a plurality of road side ends in the first target area; send the position offset data to the cloud; receive rainfall data of the first target area sent by the cloud; and push rainfall warning information to a first target terminal in the second target area if the rainfall data meets a preset warning condition.

Specifically, since V2X communication (PC5 direct communication) is not affected by the cellular mobile communication network, SIM card traffic, and operator service, there is no need to worry about the problems of cellular mobile network communication quality, Internet of Things card traffic exhaustion, and operator suspension of service. Based on the V2X communication between the RSU and the OBU, timely warnings can be given to motor vehicles, pedestrians, and non-motor vehicles to avoid safety accidents caused by the displacement and opening of manhole covers. For example, when a nearby vehicle is driving in the vicinity of a manhole cover, the vehicle-end OBU will receive the manhole cover status information sent by the manhole cover-end of the manhole cover. After the vehicle-end OBU analyzes the manhole cover status information, the driver is reminded by the in-vehicle voice reminder device, such as: the manhole cover in the front road section is displaced, please pull over and park, and avoid driving after confirming the position of the manhole cover. After receiving and analyzing the manhole cover status information sent by the manhole cover-end, the road side device RSU will remind through the road side broadcast device, such as: the manhole cover in the front road section is displaced, pedestrians and non-motor vehicles should avoid. The RSU will also upload the manhole cover status information to the cloud through the uu communication interface, so that the maintenance personnel can maintain the lost manhole cover on site, and the traffic management department can timely go to the scene for traffic management to avoid traffic dangers.
