At present, the highway operation control area traffic safety guidance system is mainly laid by manual, which is not standard, not standardized and not accurate. Especially the setting distance and position of signboards, signal lights, warning lights, traffic cones and other highway maintenance safety facilities do not fully meet the requirements of highway maintenance safety operation regulations, resulting in many safety hazards in highway operation site, and even serious traffic accidents. In addition, when the construction personnel lay highway maintenance safety facilities, they cannot truly lay them according to the highway maintenance safety operation regulations because they are not familiar with the regulations, and they cannot achieve safety protection. Therefore, it is necessary to provide a highway operation Internet of Things method.

[0076] like Figures 1 to 10As shown, the present invention provides a highway operation IoT method and system. Leveraging the Internet of Things, satellite positioning technology, and artificial intelligence, the system systematically manages all aspects of the entire highway operation process. In conjunction with the Highway Maintenance Safety Operations Regulations (JTG H30-2015), national standards, and industry standards, the system automatically generates an operation control area layout plan, guides on-site operation layout, verifies the actual layout, and simultaneously manages the safety of the operation and maintenance site. The highway operation IoT method provided by the present invention automatically generates an operation control area layout plan based on the Highway Maintenance Safety Operations Regulations (JTG H30-2015), national standards, and industry standards. Relevant standards include, but are not limited to, the Highway Maintenance Safety Operations Regulations (JTG H30-2015), national standards, industry standards, and so on. When relevant standards and specifications are updated, the layout plan of the present invention will be adjusted accordingly to ensure compliance with the latest relevant standards and specifications. The present invention can be widely applied to scenarios such as highways, bridges and culverts, tunnels, toll plazas, intersections, traffic engineering projects, roadside facilities, and special road sections. The highway operation IoT method of the present invention can be widely used in highway operations in various scenarios such as highway maintenance safety operations, highway construction operations, and highway repair operations.

[0077] The present invention provides a highway operation Internet of Things method, including an information acquisition and analysis step: acquiring detection information and analyzing the detection information; a deployment plan generation step: generating a deployment plan according to the analysis result; a task generation and scheduling step: generating a work task according to the deployment plan to schedule people, vehicles and objects, including personnel, vehicles, equipment, highway maintenance safety facilities, machinery, materials, work tools, etc.; a warehouse outbound management step: performing warehouse outbound management on the dispatched vehicles, equipment, highway maintenance safety facilities, machinery, materials, and work tools; a deployment guidance step: guiding the workers to deploy highway maintenance safety facilities according to the work tasks; a review and verification step: comparing the actual situation of the on-site deployment with the plan for review and verification; a monitoring step: issuing a redeployment prompt for those that do not comply with the plan after the review and verification, taking effect after passing the review and verification, performing safety monitoring on the workers at the work site, and monitoring external intrusions; a recovery and verification step: after completing the work, the highway maintenance safety facilities are recovered and the vehicles and objects are checked for storage; an information external release step: releasing different information at different stages of the highway maintenance operation.

[0078] More specifically, the detection information is obtained through any one or more of deformation monitoring equipment, road pavement defect detection equipment, road traffic facility defect detection equipment, third-party notifications, and manual inspections. The deformation monitoring equipment is deployed on the road and surrounding terrain to sense changes in the conditions at its location. The road pavement defect detection equipment is used to collect road pavement defect information. The road traffic facility defect detection equipment is used to collect defect information on traffic facilities such as guardrails, gantries, and light poles. Third-party notifications include information reported by the public via telephone and information pushed by third parties.

[0079] When analyzing the detection information, the detection information is analyzed in combination with the influencing factors, and the influencing factors include any one or more of the following: road information, traffic volume at the work site, type of work, weather, degree of damage, and material inventory at the diseased part.

[0080] The scheduling of people, vehicles and materials includes the scheduling management of staff, vehicles, equipment, highway maintenance and safety facilities, machinery, materials, and work tools, combined with personnel shifts, etc.

[0081] In the warehousing and outbound management steps, based on the number of personnel, vehicles, equipment, highway maintenance safety facilities, machinery, materials, and operating tools required for the operation, their outbound records and management are made when the operating personnel receive them.

[0082] In the information release step, the detected traffic accident information, natural disaster information and road disease information, the construction time and location information of the operation task, the accident location and the time of the accident are released to the outside through the information release system.

[0083] In the deployment guidance step, the highway maintenance safety facilities are installed with an intelligent monitoring terminal for judging the working status of the highway maintenance safety facilities, and the deployment of the highway maintenance safety facilities is guided according to the set position of the highway maintenance safety facilities in the operation task and the position reported in real time by the highway maintenance safety facilities.

[0084] Operators use handheld devices to view the real-time location of road maintenance and safety facilities and move them to the designated location according to instructions. If there are a large number of road maintenance and safety facilities and the operator cannot distinguish the corresponding location of the road maintenance and safety facilities on the handheld device during the operation, the operator can move one of the road maintenance and safety facilities and use the position movement information provided by the handheld device to determine the specific location of the traffic safety device on the handheld device and guide the road maintenance and safety facility to the designated location.

[0085] In the review and verification step, the position calculation is performed on the set position in the highway maintenance safety facility layout plan and the position reported in real time by the highway maintenance safety facility terminal. If the calculation result is greater than the set error range, the review and verification fails; if the calculation result is less than or equal to the set error range, the review and verification passes.

[0086] The monitoring step includes an electronic fence generation step: obtaining the locations of highway maintenance safety facilities equipped with positioning functions, and generating an electronic fence based on the locations, wherein the electronic fence is bound to the on-site workers wearing positioning terminals; an early warning alarm step: judging the positional relationship between the workers wearing positioning terminals and the electronic fence, and when the workers approach the safety value of the electronic fence, the positioning terminal issues an early warning message, and when the workers leave the area set by the electronic fence, the positioning terminal issues an alarm message; an external intrusion monitoring step: the highway maintenance safety facilities equipped with positioning and status detection enter the monitoring state and monitor external intrusions.

[0087] In the recycling verification step, after the operation is completed, the unique identification on the vehicles, equipment, highway maintenance safety facilities, machinery, materials, and work tools is checked against the records at the time of leaving the warehouse. If the check fails, the operator is prompted to recheck.

[0088] The present invention also provides a maintenance safety operation Internet of Things system, including an information acquisition and analysis module: which obtains detection information and analyzes the detection information; a layout plan generation module: which generates a layout plan according to the analysis results; a task generation and scheduling module: which generates operation tasks according to the layout plan to schedule people, vehicles and objects; a warehouse outgoing management module: which performs warehouse outgoing management on the scheduled vehicles and objects; a layout guidance module: which guides operators to deploy highway maintenance safety facilities according to the operation tasks; a review and verification module: which compares the actual situation of the on-site layout with the plan and conducts review and verification; a monitoring module: which prompts redeployment for those that do not meet the plan after the review, and takes effect after the review and verification is passed, performs safety monitoring of operators at the operation site, and monitors external intrusions that affect the operation; a recovery and verification module: which recovers the highway maintenance safety facilities and verifies the vehicles and objects into the warehouse after the operation is completed; and an information external release module: which releases different information to the outside at different stages of highway operations.

[0089] Furthermore, according to a highway operation IoT method provided by the present invention, Figure 1 and Figure 2 As shown, the following steps are included:

[0090] Step 1: Push the traffic accident, natural disaster and highway disease information detected by the highway maintenance safety facility status monitoring terminal, deformation monitoring device, highway pavement disease detection device and manual inspection to the operation demand acquisition and analysis system and the information external release system.

[0091] Step 2: The operation demand acquisition and analysis system analyzes actual traffic accidents, natural disasters, road diseases and other conditions at the operation site by combining the acquired information with relevant standards, and pushes the analysis results to the layout plan generation system.

[0092] Step 3: The deployment plan generation system generates the parameters of the operation control area, the operation time and location, and the types and quantities of personnel, vehicles, equipment, highway maintenance and safety facilities, machinery, materials, and operation tools required for the operation. This information is then pushed to the operation task generation system and the scheduling system.

[0093] Step 4: The task generation system and the personnel, vehicle, equipment, highway maintenance and safety facilities, machinery, materials, and tool scheduling system generate the task content and schedule personnel, vehicles, equipment, highway maintenance and safety facilities, machinery, materials, and tools. The inbound and outbound management system manages outbound shipments. Simultaneously, the task generation system and the personnel, vehicle, equipment, highway maintenance and safety facilities, machinery, materials, and tool scheduling system generate the task information and push it to the information publishing system.

[0094] Step 5: The workers arrive at the work site and deploy the highway maintenance safety facilities according to the deployment guidance provided by the highway maintenance safety facility on-site deployment guidance system. After the deployment is completed, the deployment compliance review system conducts a standardized review of the actual situation of the on-site deployment.

[0095] Step 6: After the review and inspection is passed, the highway maintenance safety management system will take effect and safety monitoring will be carried out on the workers at the work site.

[0096] Step 7: After the review and inspection is passed, monitor and manage external intrusions that affect safe operations.

[0097] Step 8: After the operation is completed, the vehicles, equipment, road maintenance safety facilities, machinery, materials, work tools, etc. are safely recovered and compared with the models and quantities when they were shipped out in the warehouse management to avoid secondary hazards caused by tools left at the work site.

[0098] Step 9: Develop a maintenance safety operation emergency plan for long-term highway maintenance operations and activate the emergency plan in a timely manner when an emergency occurs.

[0099] Further explanation, such as Figure 4 As shown, the described step 1 includes the following steps:

[0100] Step 1.1: Install smart monitoring terminals on existing road infrastructure (such as guardrails, light poles, and gantries) and bind them to the corresponding smart monitoring terminals through the system. Specifically, staff use a high-precision positioning tablet or other functional terminal to scan the smart monitoring terminal's QR code, record the smart monitoring terminal's high-precision location, and upload it to the backend server.

[0101] Step 1.2: Determine the working status of the highway traffic facilities through the intelligent monitoring terminals installed on the highway traffic facilities.

[0102] Furthermore, Figure 3 As shown in the figure, the intelligent monitoring terminal consists of three main components: an MCU, an accelerometer, and a communication module. The MCU is connected to the communication module and the accelerometer. The accelerometer acquires status information about road traffic facilities and feeds it back to the MCU. The MCU then determines the operating status of the road traffic facilities based on this information and returns the information via the communication module.

[0103] The intelligent highway monitoring terminal uses an accelerometer to record the initialization status of the installed highway traffic equipment, primarily recording acceleration and angle information. Once an acceleration change triggers an interrupt, the MCU uses an algorithm to compare the initialization status with the equipment's initialization status to determine the equipment's motion type and push an alarm to the backend server. The equipment also performs self-tests at regular intervals, checking its battery level, signal level, angle, and other information, and pushes this information to the backend server.

[0104] Step 1.3: Deploy deformation monitoring equipment on special highways and surrounding bridges, culverts, slopes, and other terrain to detect displacement changes at the designated locations. This provides early warning of landslides and landslides, and transmits these warnings to a backend server via the internet.

[0105] Step 1.4: Use the road surface defect detection equipment to complete the real-time acquisition of high-definition road surface images. The acquired road surface images are processed by the image processing software system to generate the defect locations. The road surface defect detection equipment can be loaded onto a specialized vehicle to acquire road surface images.

[0106] Step 1.5: Staff record the disease locations through inspections and manually upload them to the backend server.

[0107] Step 1.6: Obtain testing information through a third party, such as through public telephone reports or third-party push notifications.

[0108] It should be pointed out that the information collection of the present invention is not limited to the above-mentioned method, and collection by other methods also falls within the protection content of the present invention.

[0109] Further explanation, such as Figure 5 As shown, the described step 2 includes the following steps:

[0110] Step 2.1: The operation demand acquisition and analysis system analyzes and classifies the acquired disease information, first analyzing the road information.

[0111] More specifically, the system determines the road level by combining the coordinates of the defect location reported in step 1 with map information, for example, the level may be a highway, a first-class highway, a second-class highway, a third-class highway or a fourth-class highway, a tunnel, a bridge, a culvert, a toll plaza, etc.

[0112] The system uses coordinates combined with map information to determine road conditions, such as lane type, whether the oncoming lane needs to be used, whether it is an interchange entrance or exit, and the final speed limit for that section. Traffic volume Q at the operating point is calculated using nearby LiDAR and cameras. The system also obtains weather information via the internet and sensors located near the highway.

[0113] Step 2.2: Determine the type of operation based on the job content and the time required. If the job content is extensive and the work time exceeds 24 hours, long-term maintenance is required. Conversely, if the job content is small and the work time exceeds 4 hours but less than 24 hours, short-term maintenance is required. If the job content is small and the work time exceeds 30 minutes but less than 4 hours, temporary maintenance is required. If the job content requires continuous movement or the maintenance time is less than 30 minutes, it is defined as mobile maintenance.

[0114] Step 2.3: The system automatically searches for the corresponding operating standards based on the results obtained in steps 2.1 and 2.2.

[0115] More specifically, the Operation Requirements Acquisition and Analysis System includes an Operation Requirements Acquisition Portal, which is used to obtain information on defects and the status of highway traffic facilities. Information channels include deformation monitoring systems, highway traffic facility status monitoring systems, highway pavement defect detection systems, inspection upload systems, highway traffic facility defect detection equipment, and third parties. The Operation Requirements Acquisition Portal acquires location information and defect information. Location information is sent to the Weather Information Module, which retrieves weather information, the Road Recognition Module, the Map Recognition Module, and the Traffic Volume Calculation Module. Defect information is sent to the Operation Type and Operation Complexity Determination Modules, and ultimately, through the Standard Search Module, to the On-site Deployment Guidance and Recommendation Generation Module of the Deployment Plan Generation System.

[0116] More detailed description, such as Figure 11As shown, the application also includes a traffic volume acquisition module: acquiring traffic volume data of the work section, collecting the traffic volume of the section through the camera and radar installed around the work section, and uploading to the traffic volume calculation module in real time. The collected data includes the number of cars passing through the section per unit time and the speed of the cars.

[0117] The traffic volume calculation module of the application calculates the current traffic volume of the section according to the acquired traffic volume data, and finally generates the minimum length of the warning zone in the standard finding module according to the current traffic volume and the historical traffic volume of the section, combined with the design speed of the highway, the grade of the highway and the minimum speed after speed limit.

[0118] According to the current traffic volume and the historical traffic volume of the section, combined with the work time generated according to the work content, the final work time requirement is generated in the standard finding module. For example, for the section with heavy traffic congestion and accident impact, the required work time is short; for the section with many lanes, less traffic flow or less accident, the allowed work time is relatively long.

[0119] The identification of the work site includes: acquiring the design speed of the road, and the identification of the lane information includes: acquiring the number of lanes, the width of the lane and the position of the work lane. It can be acquired by querying in the highway network system.

[0120] The standard finding module includes:

[0121] - acquiring the required work time and road traffic volume information, analyzing the time characteristics of the traffic volume, and generating reasonable work time;

[0122] - acquiring the traffic volume of the road, the design speed of the highway, the grade of the highway and the minimum speed of the speed limit section, calculating the gradual speed reduction interval of the warning zone according to the design speed of the highway, and setting the minimum length of the warning zone;

[0123] - acquiring the minimum speed of the speed limit interval, generating the minimum length of the upstream transition zone and the minimum length of the longitudinal buffer zone;

[0124] - acquiring the number of lanes, the width of the lane and the position of the work lane, and generating the width of the transverse buffer zone;

[0125] - acquiring the work area and work object information, and setting the work zone length;

[0126] - acquiring the work lane position, and setting the large truck parking area;

[0127] - acquiring the work type, and judging according to the time required by the work content;

[0128] - then generate the minimum length of the downstream transition zone and the minimum length of the termination zone.

[0129] The present invention includes a disease and accident perception module for generating operation geographic location information, and the disease and accident perception module includes:

[0130] IoT accident perception module: Sense the occurrence of traffic accidents and natural disasters through IoT devices; IoT devices include monitoring equipment installed on traffic facilities, such as surveillance cameras installed on gantry frames.

[0131] Defect perception module: Obtains road defect information through data collected by defect detection vehicles or through video analysis.

[0132] The information obtained by the IoT accident perception module and the disease perception module is uploaded in real time and analyzed. The final highway maintenance plan is generated based on the severity of the accident, the degree of damage to the road surface, and the material inventory status of the diseased area.

[0133] At the same time, the system retains a manual parameter input entrance, allowing staff to manually input work content. Road hazards discovered by staff during inspections and road hazard information uploaded by drivers can be entered through the manual parameter input entrance.

[0134] The weather information acquisition module obtains the weather information of the road section through the Internet, including real-time weather and weather forecasts. The standard search module receives weather information, makes corresponding adjustments to the operation control area based on different weather factors, and adds corresponding highway maintenance safety facilities according to the standards. At the same time, the system can obtain the actual environmental conditions of the operation site based on the actual on-site environmental monitoring sensors, including temperature, humidity, wind speed and direction, and other information, and feedback to the on-site staff to adjust the layout of the operation site.

[0135] The layout plan generation system includes an on-map operation information generation module, an operation time calculation module and an operation demand calculation module; the on-map operation information generation module generates the geographical location of the operation control area, the corresponding positions of each part of the operation control area, the traffic safety setting positions of each area and the speed limit sign positions of each area; the operation time calculation module generates the ideal start time, operation duration and the latest end time; the operation demand calculation module calculates the number of operating personnel, the number of various highway maintenance safety facilities and the number of operating vehicles.

[0136] The layout plan generation module displays the generated information of each area through a map, generates simpler and more intuitive layout suggestions, and standardizes the start time and the latest end time of the operation based on the calculated ideal operation time and the duration required for the operation. At the same time, based on the operation content and the parameters of the operation control area, it calculates the types and quantities of personnel, vehicles, equipment, highway maintenance safety facilities, machinery, materials, and operation tools required for this operation.

[0137] Further explanation, such asFigure 5 As shown, the described step 3 comprises the following steps:

[0138] Step 3.1: The system automatically generates the job site layout guidance suggestion by analyzing the found content through step 2.1, step 2.2, and step 2.3.

[0139] Specifically, the system calculates the ideal operation time according to the obtained road level and the actual construction area size, real-time traffic volume Q, and historical traffic volume Q, generates the parameters and layout scheme of the maintenance operation control zone according to the obtained weather forecast information during the maintenance operation, including all parameter values of the final speed limit value, warning zone in the maintenance operation control zone, upstream transition zone, longitudinal buffer zone, transverse buffer zone, operation zone, downstream transition zone, termination zone, and large truck parking area, and reasonably increases the parameters of the operation maintenance control zone according to the weather.

[0140] Step 3.2: After the completed layout scheme guidance suggestion is generated, the system matches the corresponding personnel, vehicles, equipment, highway maintenance safety facilities, machinery, materials, and operation tools according to the maintenance operation control zone parameters.

[0141] Step 3.3: The system pushes the complete job site layout scheme guidance suggestion to the dispatch management of personnel, vehicles, equipment, highway maintenance safety facilities, machinery, materials, and operation tools, and generates the maintenance operation dispatch management.

[0142] Further explanation, as shown in Figure 6 The described step 4 comprises the following steps:

[0143] Step 4.1: After the job site layout scheme guidance suggestion is obtained by the operation task generation system and the dispatch management system of personnel, vehicles, equipment, highway maintenance safety facilities, machinery, materials, and operation tools, the number of personnel, vehicles, equipment, highway maintenance safety facilities, machinery, materials, and operation tools generated in step 3.2 is combined with the personnel shift for related dispatch. The on-site layout guidance suggestion considers multiple dimensions such as operation control zone parameters, operation time suggestion, operation location, operation personnel, vehicle quantity, highway maintenance safety facilities, and material quantity.

[0144] More optimally, the system is provided with an approval module, and the number of personnel, vehicles, equipment, highway maintenance safety facilities, machinery, materials, and operation tools can be dispatched after the job site layout scheme guidance suggestion passes through the approval module. If the job site layout scheme guidance suggestion does not pass the approval, the scheme needs to be re-quantified to generate the job site layout scheme guidance suggestion.

[0145] Step 4.2: The inventory management system for personnel, vehicles, equipment, highway maintenance safety facilities, machinery, materials, and operating tools records the inventory when the operating personnel receive them according to the quantity required for the operation.

[0146] More preferably, the number of personnel, vehicles, equipment, highway maintenance safety facilities, machinery, materials, and work tools shipped out should be greater than or equal to the number required in the maintenance work site layout plan guidance recommendations (the maintenance work system automatically calculates the required number of various materials and tools). For example, if the number of Facility A required in the work site layout plan guidance recommendations is 100, then the number of Facility A shipped out should preferably be greater than or equal to 100. If the number of Facility A in stock is less than 100, the operator will be prompted to replenish Facility A until the number of Facility A available for shipment reaches the specified number.

[0147] Step 4.3: The system extracts the construction start time and location from the task and pushes them to the information release system. Specifically, the information release system pushes the task information to various distribution channels (such as variable traffic information signs, traffic broadcasts, online media, information service platforms, and map providers), prompting drivers to avoid obstacles and plan their routes as early as possible.

[0148] Further explanation, such as Figure 7 As shown, the described step 5 includes the following steps:

[0149] Step 5.1: The operator arrives at the work site according to the work task information obtained in step 4.1.

[0150] Specifically, the system plans the departure time and route for the staff according to the work location and work time in the task. The staff takes a work vehicle equipped with a satellite high-precision vehicle monitoring terminal and follows the navigation prompts to arrive at the work site. After arriving at the work site, the vehicle is parked in the vehicle parking area in the layout plan.

[0151] Step 5.2: The operating personnel begin to deploy highway maintenance safety facilities according to the deployment plan guided by the highway maintenance safety operation system.

[0152] Specifically, the operating personnel hold a mobile device with the highway maintenance safety management system APP installed. The APP contains the current highway maintenance safety deployment plan and records of the number of personnel, vehicles, equipment, highway maintenance safety facilities, machinery, materials, and operating tools. According to the deployment plan guided by the highway maintenance safety operation system, different types of highway maintenance safety facilities equipped with intelligent monitoring terminals are deployed. After the deployment is completed, the system compares the high-precision location reported by the highway maintenance safety facility monitoring terminal through the deployment compliance review system, and calculates the location by using the high-precision location information and the location information in the deployment recommendation. Different types of highway maintenance safety facilities have different allowable deployment errors. Distances within the preset range are considered passed, and distances outside the preset range are considered failed. The system will remind the staff of points that do not meet the deployment specifications. After receiving the reminder, the staff will re-deploy the non-standard deployment points, and the system will review again until they meet the regulations and standards. That is to say, if the current actual layout does not meet the set layout requirements, corrective guidance will be given for the part that does not meet the layout requirements. Specifically, the operating personnel can be guided to adjust the corresponding highway maintenance safety facilities until the actual layout meets the set requirements.

[0153] To elaborate further, the review of the layout of highway maintenance safety facilities includes the following steps:

[0154] Step 5.2.1: Receive the location information uploaded by the deployed highway maintenance and safety facilities and compare it with the location information in the deployment plan. The positioning device installed on the highway maintenance and safety facilities sends their respective location information, which is received by the system and displayed on the map. The specific location of each highway maintenance and safety facility is compared with the preset location in the deployment plan. The positioning device can be a Beidou positioning device, Bluetooth positioning, WiFi positioning, or UWB positioning. If the deployment location of the highway maintenance and safety facility coincides with the location in the deployment plan or the error is within the required accuracy range, the deployment of the highway maintenance and safety facility is deemed qualified; if it exceeds the required accuracy range, the deployment of the highway maintenance and safety facility is deemed unqualified.

[0155] Step 5.2.2: Calculate the distance between the location of the highway maintenance and safety facilities and the location information in the layout plan. Set different tolerance ranges for different highway maintenance and safety facilities based on the error accuracy specified in national standards. Determine whether all highway maintenance and safety facilities are deployed outside of these tolerance ranges. Declare any facilities that do not meet these tolerances as unqualified. For example, the required placement accuracy for safety cones and lighting equipment differs, with safety cones typically requiring higher accuracy than lighting equipment. The national standards for each accuracy setting refer to the latest valid version.

[0156] Step 5.2.3: For the highway maintenance safety facilities that are not qualified for layout, a reminder is sent to the workers to guide them to perform secondary layout. The system sends the position information of the highway maintenance safety facilities that are not qualified for layout to the workers, reminding the workers to go to the site to perform secondary layout.

[0157] When the number of laid highway maintenance safety facilities exceeds or is less than the number of the scheme, i.e., there is missing layout or repeated layout, the missing position is reminded to the workers, reminding the workers to go to the site to check whether it is missing layout or the positioning device of the highway maintenance safety facility is malfunctioning, so as to perform secondary layout or replace the damaged highway maintenance safety facility.

[0158] When the layout site is unqualified, the system shows the position comparison result to the operation management personnel, and the system sends a secondary layout requirement to the site personnel.

[0159] Further description, the described step 6 includes the following steps:

[0160] Step 6.1: After the review, the highway maintenance safety management system takes effect, and the workers start to perform maintenance work. The position accuracy reported by the ordinary positioning terminal is usually 5-10 meters, which cannot meet the demand of highway operation. The system performs high-precision electronic fence drawing according to the high-precision position reported by the highway maintenance safety facility installed with high-precision positioning terminal at the operation site. After obtaining the high-precision point position, the system connects the point position into a polygon according to the algorithm, and draws a vector surface according to the polygon. As shown in the following figure, Figure 8 The system generates two-level electronic fences (one level is close to remind, and the other level is to alarm) according to the drawn vector surface, and the electronic fences are bound to the workers wearing satellite high-precision personnel positioning terminals. Once the electronic fence alarm is triggered, the system sends an alarm to the satellite high-precision personnel positioning terminal, prompting the worker to return to the operation area, and also sends it to the background server management end, so that the back-end manager can further pay attention to the maintenance operation site and personnel safety.

[0161] Usually, the vector surface drawn by the polygon is equivalent to the operation work surface, but there are also cases where the drawn vector surface is greater or less than the operation work surface. In the embodiment of the present application, the implementation mode of generating a vector surface and then generating an electronic fence is adopted. However, other ways of generating an electronic fence based on the point position of the highway maintenance safety facility also belong to the protection scope of the present application.

[0162] In further detail, the method of generating an electronic fence based on the position of an object of the present invention obtains the coordinates of a marker and generates a virtual electronic fence based on the coordinate position. The obtained coordinates include: generating through multiple markers arranged around the working area, or using markers moving around the working area, and the system regularly samples the coordinate information with a timestamp. Specifically, it includes:

[0163] Obtaining coordinates step: obtaining the coordinate position of the marker used to indicate the working area and uploading it to the server; specifically, the obtaining coordinates step includes: obtaining the coordinates of the marker in real time through a positioning device installed on the marker, the positioning device can be a satellite positioning device such as a Beidou positioning device or a GPS positioning device, and can also be through short-range communication technologies such as Bluetooth, WIFI, and UWB. The positioning device is installed in the marker. When laying out the marker, according to the on-site working conditions, a suitable working area is selected, and markers are placed at the edge of the working area. For example, during road construction, it is necessary to arrange markers at the outer edge of the working area to form a virtual electronic fence, and the internal space of the electronic fence is the working area. The positioning device uploads its own position to the server in real time, and the positioning device uploads its own position information to the server in real time through a mobile communication network or a local area network. The positioning device is provided with, for example, a 4G communication module for real-time networking to upload position information, and can also obtain position information through local calculation or a local area network.

[0164] The work area is indicated by an area surrounded by multiple markers, or by an area surrounded by a trajectory formed by a single marker moving around the periphery of the work area, as shown below.

[0165] The step of generating an electronic fence: generating an electronic fence in the server according to the coordinate position of the marker. Specifically, when a plurality of markers are used to surround an area to indicate the working area, the step of generating an electronic fence includes:

[0166] Display all acquired positioning coordinates on the map; place a circle of markers at the edge of the work area, and the area surrounded by the markers is the work area. Prompt the operator to click on the coordinate point on the map, and generate the corresponding vector graphics based on the coordinate point selected by the operator; refer to Figure 12 The specific operations are as follows: a boundary line is formed according to the operator clicking the first and second points on the map; a triangle is generated according to the operator clicking the third point; the final polygon is generated according to the operator's click order, and the corresponding vector graphics are generated.

[0167] There may be deviations between the vector graphics and the actual working area. When the working area is a regular shape, by placing markers at the turning points of the working area, the vector image is the same as the working area. When the working area is an irregular area, such as an arc area, or there is a working area where it is not convenient to place markers, the vector image and the actual working area do not completely overlap, and there is a case where the vector image is larger or smaller than the actual working area.

[0168] An electronic fence is generated based on the vector graphics. In this embodiment, a two-level electronic fence is generated: the first level is an approach warning, and the second level is a departure warning. When a person wearing a positioning terminal approaches or leaves the electronic fence, the system will issue an alarm. Workers within the electronic fence area are monitored for safety, reminding them not to leave the work area; other people outside the electronic fence are monitored for safety, reminding them not to approach the work area.

[0169] The electronic fence in this embodiment can be directly formed by the area surrounded by the position coordinates of the marker, or a vector graphic can be first generated from the marker coordinates, and then the electronic fence can be generated from the vector graphic.

[0170] When the area surrounded by a single marker movement trajectory is used to indicate the working area, the marker after turning on the positioning terminal will move according to the boundary of the fence. Figure 13 The steps for generating an electronic fence include: displaying the acquired positioning coordinates containing time information on a map; an operator moving a marker along the edge of the work area at a predetermined speed; the system collecting the marker's location information at a set frequency and recording the collection time, generating timestamped location information. The positioning points are then connected in chronological order, forming a trajectory on the map. The first and last positioning points are then connected to form a closed vector graphic. The higher the frequency of system collection, the more closely the generated vector image overlaps with the work area. The electronic fence is generated based on the vector graphic formed by the trajectory of the positioning points.

[0171] Modify the electronic fence steps: Decompose the generated vector graphics into multiple sub-blocks according to the positioning points, such as Figure 14 As shown, according to the sub-block selected by the operator, an electronic fence is generated for the area corresponding to the selected sub-block. When the operation in the block 1 area is completed, the operator can deselect block 1 in the server. At this time, the system generates an electronic fence for the area formed by blocks 2-6.

[0172] Step 6.2: After the layout is completed, the highway maintenance safety facility with the intelligent monitoring terminal constitutes a local area network in the maintenance operation area. The high-precision positioning terminal worn on the operation personnel reports the position information to the electronic fence system in real time. Correspondingly, the electronic fence system feeds back to the high-precision positioning terminal set on the operation personnel and the regional manager of the maintenance operation, which is convenient for on-site management.

[0173] Further explanation, after the review inspection is passed, the external intrusion is monitored and managed.

[0174] Step 7.1: After starting the operation, specifically, the intelligent positioning terminal of the highway maintenance safety facility enters the safety monitoring state. Once the acceleration sensor inside the terminal detects a collision, it immediately broadcasts through the local area network communication module.

[0175] Step 7.2: The alarm adopts multiple ways, which can alarm through the intelligent monitoring terminal worn by personnel, can provide on-site layout of high-power sound and light electric alarm equipment, and can provide operator network alarm to prevent the omission of maintenance site problems.

[0176] Step 7.3: The highway maintenance safety facility adopts a self-organizing network form to constitute a local area network in the maintenance operation area. Once the alarm is triggered, the information is notified to the staff wearing the intelligent monitoring terminal through sound, vibration, etc., to speed up the alarm transmission time and notify the on-site operation personnel to the safe area as soon as possible.

[0177] Step 7.4: The construction site is provided with a high-power sound and light electric alarm device of a local area network. When the highway maintenance safety facility encounters external intrusion alarm information, it can simultaneously issue sound, light and electric information alarm, which is suitable for all-weather operation warning and reminding in daytime and night, reminding the on-site workers to quickly evacuate to the safe area;

[0178] Step 7.5: At the same time, the highway maintenance safety facility synchronously and quickly pushes the on-site accident information to the background server management end through 4G and other means, and synchronously alarms the back-end manager. The server retrieves the camera deployed near the work site according to the accident position in the first time, captures the accident site, and traces the source.

[0179] Step 7.6: The back-end manager supports the scene in the first time.

[0180] Further explanation, as shown in Figure 10 The described step 8 includes the following steps:

[0181] Step 8.1: After the operation is completed, the operation personnel report the operation completion message through the system, and the highway maintenance safety management system releases the electronic fence relationship, releases the device task, and releases the device alarm information.

[0182] Step 8.2: After the operation is completed, the operator reports the completion of the operation through the system. After receiving the message, the system triggers the highway maintenance safety facility safety recovery system to guide the operator to recover vehicles, equipment, highway maintenance safety facilities, machinery, materials, work tools, etc.

[0183] Step 8.3: After recovery is complete, the vehicles, equipment, road maintenance and safety facilities, machinery, materials, and tools are put into storage. Specifically, the unique identifiers on the vehicles, equipment, road maintenance and safety facilities, machinery, materials, and tools are checked against the records at the time of departure. If the verification fails, the operator is prompted to recheck to prevent vehicles, equipment, road maintenance and safety facilities, machinery, materials, and tools from being left on site and causing secondary hazards. The system then inventories the remaining materials and calculates the materials consumed during this operation. In other words, by comparing and analyzing the vehicles, equipment, road maintenance and safety facilities, machinery, materials, and tools at the time of entry, they are all put into storage in a timely manner to prevent omissions during recovery.

[0184] Step 8.4: After completing the verification of vehicles, equipment, highway maintenance safety facilities, machinery, materials, and work tools, the staff will leave the maintenance work site and publish the work completion information.

[0185] It is further explained that the above are process specifications for routine highway maintenance safety operations. In actual processes, emergency plans for long-term maintenance operations and temporary emergency maintenance plans are also added.

[0186] It should be noted that the highway maintenance safety facilities described in the present invention not only refer to conventionally known highway maintenance safety facilities, such as the construction signs, construction distance signs, construction length signs, etc. in the "Highway Maintenance Safety Operation Regulations" (JTGH30-2015), but all other facilities that play a role in prompting, warning, and controlling safety are within the scope of protection of the present invention, especially the preferred and modified schemes based on the exemplary description of the present invention are also within the scope of protection of the present invention!

Calculate the distance between the location information of highway maintenance and safety facilities and the location information in the layout plan, set different error ranges for different highway maintenance and safety facilities, determine whether the layout of all highway maintenance and safety facilities exceeds the error range, and issue a layout failure prompt for highway maintenance and safety facilities that exceed the error range; For unqualified road maintenance safety facilities, the location information of the unqualified road maintenance safety facilities will be sent to the operators, reminding them to go to the location for secondary deployment; The monitoring module includes: Generate an electronic fence based on the location of the object. The coordinates of the markers are obtained and a virtual electronic fence is generated based on the coordinate position. The obtained coordinates include: generating through multiple markers around the working area, or using markers to move around the working area. The system regularly samples the coordinate information with timestamps, including: Coordinate acquisition module: The coordinates of the markers are acquired in real time through the positioning device installed on the markers. When laying out the markers, the markers are placed at the edge of the work area according to the on-site work conditions, thereby forming a virtual electronic fence. The space inside the electronic fence is the work area. The positioning device uploads its own position to the server in real time through the mobile communication network or local area network. The positioning device uploads its own position information to the server in real time. The work area is indicated by the area surrounded by multiple markers, or by the area surrounded by the trajectory formed by a single marker moving around the periphery of the work area. Generate electronic fence module: Generate electronic fence in the server according to the coordinate position of the marker. When the area surrounded by multiple markers is used to indicate the working area, the module includes: Display all acquired positioning coordinates on a map; place a circle of markers at the edge of the work area, and the area enclosed by the markers is the work area. Prompt the operator to click on the coordinate points on the map. The operator clicks on the first and second points on the map to form a boundary line; the operator clicks on the third point to generate a triangle; the final polygon is generated according to the order of the operator's clicks, and the corresponding vector graphics are generated; When the work area is regular in shape, markers are placed at the inflection points of the work area. In this case, the vector image is the same as the work area. When the work area is irregular, or there is a work area that is not convenient for placing markers, the vector image does not completely overlap with the actual work area. In some cases, the vector image may be larger or smaller than the actual work area. Generate an electronic fence based on vector graphics. When a person wearing a positioning terminal approaches or leaves the electronic fence, an alarm will be issued. The safety of workers in the electronic fence area will be monitored, and workers will be reminded not to leave the work area. The safety of other people outside the electronic fence will also be monitored, and other people will be reminded not to approach the work area. The electronic fence can be directly formed by the area enclosed by the position coordinates of the marker, or a vector graphic can be generated from the marker coordinates, and then the electronic fence can be generated from the vector graphic; When the area surrounded by the movement trajectory of a single marker is used to indicate the working area, the marker after the positioning terminal is turned on is moved according to the boundary of the fence. The module for generating the electronic fence includes: displaying the obtained positioning coordinates containing time information on a map; the operator moves the marker along the edge of the working area at a certain speed, collects the position information of the marker at a set frequency, and records the collection time to obtain position information with a timestamp; connects the positioning points according to the time sequence, connects the multiple positioning points into a trajectory on the map, connects the first and last two positioning points to form a closed vector graphic; and generates the electronic fence according to the vector graphic formed by the positioning point trajectory; Modify the electronic fence module: decompose the generated vector graphics into multiple sub-blocks according to the positioning points, and generate an electronic fence for the area corresponding to the sub-block selected by the operator.
