Abstract
Description
Technical Field
[0001] This invention relates to the field of information technology, and in particular to a third-party monitoring method for road transport safety management. Background Technology
[0002] Vehicle monitoring is a core component of the daily operations of transportation and logistics companies, directly impacting driving safety, cost control, and compliance management. With the continuous increase in the number of vehicles and the expansion of operational areas, real-time monitoring of vehicle location, status, and behavior has become paramount. Only by accurately and promptly understanding the actual operation of each vehicle within complex road networks can companies effectively prevent accidents, optimize dispatching, and meet regulatory requirements.
[0003] However, existing vehicle monitoring methods have revealed significant shortcomings in practical applications. While most systems can collect vehicle location and speed data, they struggle to closely correlate this data with specific management rules set by the company. This leads to frequent misjudgments regarding behaviors such as vehicles deviating from planned routes, entering restricted areas, or prolonged speeding. Furthermore, once the system issues an alarm, company managers often face the dilemma of incomplete information or insufficient evidence, making it difficult to quickly distinguish between genuine violations and legitimate situations, resulting in frequent false alarms or missed detections. Moreover, when vehicles are in abnormal operating conditions due to maintenance, repairs, or loan, existing systems struggle to clearly record and track the start time and changes in these states, leaving managers facing situations of missing or confused information when querying vehicle history or determining liability.
[0004] These problems are closely interconnected. Because electronic fences have a uniform and fixed shape, they cannot flexibly adapt to the actual management needs of different routes, time periods, or vehicle types. This makes it easy for the system's judgments of boundary crossings and speeding to become disconnected from the company's true intentions. This disconnect directly leads to a surge in the number and quality of alarms, forcing companies to invest significant manpower to verify the authenticity of each alarm. The time-consuming and inconsistent verification process further exacerbates the contradiction between real-time performance and accuracy in the entire monitoring system, making it difficult to promptly identify and isolate abnormal behavior of vehicles in special situations. For example, if a truck that regularly delivers goods in the city is temporarily reassigned to long-distance transport in the suburbs, and the fence rules are not adjusted in time, the frequent boundary crossings will overwhelm valuable verification work. Furthermore, if the truck temporarily stops at an unexpected location due to tire failure, the system cannot mark its special status, nor can management quickly find the cause of this anomaly, ultimately leading to the concealment of safety hazards or unclear division of responsibility.
[0005] Therefore, how to establish a precise matching and rapid response mechanism between multi-source data such as vehicle location and speed and the diversified and dynamic management rules of enterprises, and to form a standardized and transparent verification channel after an alarm is generated, while achieving clear status tracking and traceability of abnormalities for vehicles in special states such as maintenance or borrowing, has become a key issue that urgently needs to be solved in the current field of vehicle monitoring. Summary of the Invention
[0006] This invention provides a third-party monitoring method for road transport safety management, mainly including:
[0007] After logging into the monitoring platform via a browser, users are taken to the homepage, which displays basic data overviews of all vehicles under their jurisdiction, pending tasks, and recent alarm summaries. Following user input, they enter the monitoring center, where the real-time location information of their managed vehicles is displayed on a map, and various abnormal alarm information is received and processed. The monitoring platform allows the creation of electronic fences with various geometric shapes, including circles, rectangles, polygons, lines, and key points. For each electronic fence, entry and exit alarm rules, effective alarm time periods, and speed limits are set, and the electronic fences are assigned and bound to target vehicles. The monitoring platform determines vehicle entry and exit based on vehicle satellite positioning data. The system assigns the status of electronic fences and generates area-based alarms when boundaries are crossed or speed limits are violated; it executes verification and processing procedures for various alarms generated by the monitoring platform, including platform alarms and active safety alarms, and supports enterprise users to appeal the verification results and conduct subsequent reviews; it marks the status of vehicles in special states such as being out of service, under maintenance, scrapped, or suspended from monitoring, and provides abnormal movement records and offline time statistics queries; it pushes announcement documents to subordinate enterprises or initiates safety inspection tasks, requiring enterprises to submit reading receipts or inspection responses; it generates statistical reports on a daily, weekly, monthly, and yearly basis, and supports scheduled automatic or instant push to designated email addresses.
[0008] Furthermore, the creation of electronic fences with various geometric shapes, including circles, rectangles, polygons, lines, and key points, and the setting of entry and exit alarm rules, alarm validity periods, and speed limits within each electronic fence, includes: the fence management module displays all created electronic fences grouped by type, and supports viewing details, viewing assigned vehicles, modifying, enabling, disabling, and deleting individual electronic fences; for circular electronic fences, the center point and radius are set using map tools, and entry and exit alarms, alarm validity periods, and speed limits within the area are configured; for rectangular or polygonal electronic fences, the coordinates of each vertex are determined sequentially using a map, and the electronic fence name, entry and exit alarm rules, alarm validity periods, and speed limits within the area are configured; for line or key point electronic fences, a path point sequence or center point radius is set, and multiple coexisting alarm validity periods and corresponding alarm conditions are configured; the configured electronic fences are assigned to target vehicle lists according to region or enterprise, and the assignment status is recorded.
[0009] Furthermore, the monitoring platform determines the vehicle's entry and exit status from the assigned electronic fence based on the vehicle's satellite positioning data, including: acquiring the vehicle's satellite positioning data and calculating the distance between the vehicle's current position and the electronic fence boundary; if the vehicle's current position exceeds the electronic fence boundary or violates the speed limit conditions within the area, an area-based alarm is generated, and the vehicle identifier and alarm time are associated.
[0010] Furthermore, the process for verifying and processing various alarms generated by the monitoring platform, including platform alarms and proactive safety alarms, includes: a real-time alarm list displaying alarm records that have not yet been verified, supporting the sending of reminder messages to alarm vehicles via terminals; an alarm verification module verifying the warning, false alarm, normal, and serious violation levels of platform alarms and proactive safety alarms, recording the verifier and the processing result; if there is a dispute over the verification result, receiving an appeal application submitted by the enterprise, displaying the alarm details associated with the appeal, and having a user with review authority approve or reject the appeal.
[0011] Furthermore, the system marks vehicles in special states such as being out of service, under maintenance, scrapped, or suspended from monitoring, and provides anomaly records and offline duration statistics queries. This includes: the vehicle management module importing vehicle information in batches using templates, and performing outage, maintenance, scrapping, suspended monitoring, and monitoring resumption operations on selected vehicles; the outage vehicle anomaly query module displaying the start and end times, start and end locations, operating mileage, and maximum speed records during the period for vehicles marked as out of service; and the offline reminder module compiling and querying a list of vehicles that have not been online within 24 hours and vehicles that have been offline for more than a set period of time.
[0012] Furthermore, the vehicle management module imports vehicle information in batches through templates and performs operations such as shutdown, maintenance, scrapping, suspension of monitoring, and resumption of monitoring on selected vehicles. This includes: parsing the basic vehicle information in the imported template, including license plate number and vehicle type; applying status markers to selected vehicles and updating the vehicle status field; recording the status change time and operator information; and if the status is shutdown, starting abnormal movement monitoring and capturing location change records.
[0013] Furthermore, the step of pushing announcement documents or initiating security check tasks to subordinate enterprises and requiring enterprises to submit reading receipts or check responses includes: the announcement management module sending text announcements to selected enterprises and setting whether reading receipts are required; the document distribution module pushing attachment files to selected enterprises and recording the enterprise's download status and confirmation of reading status; the security check module issuing check tasks to designated enterprises and requiring enterprises to submit a check situation description or photo / video proof materials within a limited time; receiving reading receipts or check responses submitted by enterprises and recording the submission status.
[0014] Furthermore, the generation of statistical reports on daily, weekly, monthly, and yearly cycles, and the support for scheduled automatic or instant push to specified email addresses, includes: the report center generating daily, weekly, monthly, or annual reports containing alarm counts, online rates, location rates, and trajectory integrity rates based on the selected region, enterprise, and time range; the push management module setting scheduled push email addresses and push times for enterprises; and the instant push module selecting all regions or specified enterprises to immediately send the specified period reports to multiple email addresses, recording the sending status and receiving email addresses in the push log.

Attached Figure Description
[0017] Figure 1 This is a flowchart of a third-party monitoring method for road transport safety management according to the present invention. Detailed Implementation
[0018] The technical solutions of the embodiments of the present invention will be clearly and thoroughly described below with reference to the accompanying drawings. The described embodiments are merely some embodiments of the present invention.
[0019] like Figure 1 This embodiment of a third-party monitoring method for road transport safety management may specifically include:
[0020] S1. After logging into the third-party monitoring platform through a browser, the user enters the homepage, which displays the basic data overview of all vehicles under the current user's jurisdiction, the list of pending matters, and the summary information of recent alarms.
[0021] The user enters the monitoring center, which displays the real-time location information of the vehicles under its jurisdiction on a map and receives and processes various abnormal alarm information. Preferably, a web browser is used.
[0022] S2 creates electronic fences with various geometric shapes, including circles, rectangles, polygons, lines, and key points, in the monitoring platform. It sets entry and exit alarm rules, multiple coexisting alarm effective time periods, and speed limit conditions within the area for each electronic fence, and then assigns the created electronic fences to target vehicles.
[0023] S3, the third-party monitoring platform determines the vehicle's entry and exit status from the assigned electronic fence in real time based on the vehicle's satellite positioning data, and generates corresponding area-type alarms when the vehicle crosses the boundary or violates the speed limit.
[0024] S4. For various alarms generated by third-party monitoring platforms, including regional platform alarms and proactive security alarms, the platform executes a unified verification process and records the verification results. The verification process supports enterprise users to appeal the verification results and allows users with review authority to approve or reject them.
[0025] Specifically, a unified verification process is implemented for all types of alarms generated by third-party monitoring platforms, generating and storing the verification results. Furthermore, users can appeal any verification result, which triggers a review sub-process. This review sub-process is handled by users with review permissions, who either approve the appeal (i.e., correct the original verification result) or reject the appeal (i.e., maintain the original verification result). The processing result is recorded and stored in association with the original alarm and verification result. If the appeal is approved, the status is automatically updated, and subsequent operations, such as deactivating false alarms, may be initiated as appropriate.
[0026] S5, the monitoring platform marks the status of vehicles in special operating states such as shutdown, maintenance, scrapping, and suspension of monitoring, records and provides abnormal records of the vehicles during the special state and offline duration statistics query function.
[0027] For example, when a vehicle enters a special operating state, such as being out of service, under maintenance, scrapped, or having its monitoring suspended, the platform activates a special state identifier for the vehicle and records the start time, type, and triggering reason of this state. Throughout the entire period the special state identifier is active, the platform receives and stores various types of vehicle data, including but not limited to: GNSS positioning data, GAN bus data, and onboard equipment communication status, forming a complete data chain for that period. The platform provides a dedicated query interface for this period, allowing users to query:
[0028] Abnormal activity record: Based on the data chain during the period, the platform can trace back and display all key events of the vehicle during this period, such as unauthorized movement, engine start, etc., and the time when they occurred.
[0029] Offline duration statistics: The platform analyzes the communication logs of the vehicle-mounted equipment during this period, accurately calculates the total duration of communication interruption and the last online time, and can generate an offline duration distribution map.
[0030] S6, the monitoring platform pushes announcement documents to the enterprises under its jurisdiction or initiates security check tasks, and requires the enterprises to submit reading receipts or check response materials within a limited time.
[0031] Specifically, the monitoring platform can push announcement documents to the terminals of the enterprises under its jurisdiction or create and initiate a security check task. For announcements, it can be set whether enterprises are required to submit a read receipt within a specified time period; for documents, it needs to record the download status and confirmation of read status; for security check tasks, it requires the receiving enterprises to submit check response materials containing specified content such as on-site photos, videos, inspection records, etc. within the task period.
[0032] Furthermore, the platform monitors the feedback status of each announcement or task in real time, records whether it is submitted on time and whether the submitted content meets the requirements, and marks and warns cases of failure to submit on time or submission that is not up to standard.
[0033] S7 generates statistical reports on a daily, weekly, monthly, and yearly basis, and supports scheduled automatic or instant push to a specified email address.
[0034] Specifically, it generates statistical reports based on the jurisdiction and specified time period, including multiple indicators such as alarm count, online rate, location rate, and trajectory integrity rate, and supports scheduled automatic push or instant push to specified email addresses.
[0035] S21. Create various geometric shapes of electronic fences, set rules, and then assign them to target vehicles. This includes: the fence management module displays all created electronic fences grouped by type and supports operations such as viewing details, viewing the list of assigned vehicles, modifying rules, enabling, disabling, and deleting individual electronic fences. S22. For circular electronic fences, use map tools to set the center point coordinates and radius value, and configure entry and exit alarms, multiple coexisting alarm validity periods, and speed limits within the area.
[0036] S23, for rectangular or polygonal electronic fences, determines the coordinates of each vertex sequentially through a map, and configures the electronic fence name, entry and exit alarm rules, multiple coexisting alarm effective time periods, and speed limit values within the area.
[0037] S24, for line electronic fences or key point electronic fences, set the path point sequence or center point and radius, and configure multiple coexisting alarm effective time periods and the alarm conditions corresponding to each time period.
[0038] S31, the monitoring platform determines the status of the vehicle entering or leaving the assigned electronic fence based on the vehicle's satellite positioning data, including: acquiring the vehicle's satellite positioning data and calculating the distance between the vehicle's current position and the boundary of the electronic fence.
[0039] S32: If the vehicle's current location exceeds the electronic fence boundary or violates the speed limit conditions within the area, an area-based alarm will be generated, and the vehicle identification number and alarm time will be associated with it.
[0040] S41 executes verification and processing procedures for various alarms, including: displaying a real-time alarm list of alarm records that have not yet been verified and supporting the sending of immediate or scheduled reminder messages to alarm vehicles via driver terminals or enterprise terminals.
[0041] S42, the alarm processing module verifies regional platform alarms and active security alarms at different levels, such as early warning, false alarm, normal, and serious violation, and records the verifier, verification time, and final processing result.
[0042] S43, the appeal management module receives appeal applications submitted by enterprise users, displays the alarm details, verification records and related evidence associated with the appeal, and allows users with review authority to approve or reject the appeal and record the review results.
[0043] S51 allows for status marking and querying of vehicles in special operating states, including: the vehicle management module supports batch import of basic vehicle information via templates, and performs operations such as shutdown, maintenance, scrapping, suspension of monitoring, resumption of monitoring, or batch deletion on selected vehicles.
[0044] Specifically, the vehicle management module imports vehicle information in batches using templates and performs operations such as shutdown, maintenance, scrapping, suspension of monitoring, and resumption of monitoring on selected vehicles. This includes parsing the basic vehicle information from the imported template, including license plate number and vehicle type. It applies status markers to selected vehicles, updates the vehicle status field, and records the status change time and operator information. If the status is "shutdown," it initiates anomaly monitoring to capture location change records.
[0045] S52, the vehicle outage status query module displays the start and end times, start and end locations, operating mileage, and maximum speed during the period for vehicles marked as out of service.
[0046] S53, the offline reminder module compiles and queries a list of vehicles that have not been online in the last 24 hours and a list of vehicles whose cumulative offline time exceeds a set threshold.
[0047] S61 pushes announcement documents to the enterprises under its jurisdiction or initiates security check tasks, including: the announcement management module sends text announcements to enterprises within the selected scope and sets whether to require mandatory reading receipts.
[0048] S62, the file distribution module pushes attachment files to selected enterprises and records whether the enterprises have downloaded and confirmed reading them.
[0049] S63, the security check module issues check tasks to designated companies and requires them to submit a statement of the check or supporting materials such as photos and videos within a specified time.
[0050] S71 generates statistical reports and supports push notifications, including: the report center generates statistical reports on a daily, weekly, monthly, or yearly basis according to the selected region, county, enterprise, and time range. Specifically, it generates daily, weekly, monthly, or annual reports that include alarm counts, online rate, location rate, and trajectory integrity rate.
[0051] S72, the push management module allows one or more enterprises to set the scheduled email address and push time for daily, weekly, monthly and annual reports.
[0052] The S73 instant push module supports selecting all regions or specific enterprises to immediately send statistical reports for a specified period to one or more email addresses and record the sending status and receiving email addresses in the push log.
