Description

Technical Field

[0001] This invention relates to the monitoring of excavator construction, specifically to an excavator construction monitoring system and method based on pipeline protection, belonging to the field of engineering machinery safety control technology. Background Technology

[0002] Pipeline systems, as a core component of infrastructure, encompass more than ten types of critical facilities, including gas supply, power supply, water supply, and communications. They are the "lifeline" for maintaining the normal operation of cities and the daily lives of residents. Under the continuous high-intensity infrastructure construction environment, traditional pipeline protection models generally face systemic risks such as insufficient data integrity, crude detection methods, unclear responsible parties, and delayed emergency response. This leads to frequent pipeline damage accidents, seriously threatening public safety and construction progress.

[0003] Excavation work is a major cause of pipeline damage. Due to the large range of motion and numerous blind spots of excavators, construction without a clear understanding of the precise distribution of underground pipelines can easily damage existing lines. Currently, pipeline detection before construction typically relies on existing drawings combined with manual trenching and coordinate resurveying to develop relocation or protection plans. However, there is a significant disconnect between pipeline identification, plan approval, and on-site construction. The approval process largely relies on paper documents or independent office systems, failing to effectively link with the operating permissions of construction machinery such as excavators. Even before the approval process is complete, excavator operators can still start operations, posing a significant risk of unauthorized construction.

[0004] Although remote vehicle locking technology has been applied in construction machinery, its control logic is relatively simple, mostly used in scenarios such as theft prevention or rental management, and has not yet been deeply integrated with engineering safety management processes involving multi-party confirmation and multi-level approval. Furthermore, traditional monitoring methods struggle to verify in real time whether equipment is operating within designated, identifiable areas. In the event of pipeline damage, there is a lack of complete panoramic images and operational records as evidence for tracing, severely impacting the accuracy and efficiency of post-incident liability determination and accident analysis.

[0005] Therefore, in order to address the above issues, there is an urgent need to develop an excavator construction monitoring system and method based on pipeline protection, so as to achieve deep integration of project approval process and mechanical equipment operation authority, and provide key technical support for achieving safe, efficient and sustainable urban construction. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide an excavator construction monitoring system and method based on pipeline protection. This invention constructs a mandatory linkage mechanism of "no equipment start if process is not completed" and forms a traceable construction safety supervision system through panoramic imaging and full recording of operation behavior. This fundamentally eliminates illegal construction behavior caused by management gaps and significantly improves the level of pipeline protection and construction safety.

[0007] The technical solution adopted to achieve the purpose of this invention is an excavator construction monitoring system based on pipeline protection, which includes: The vehicle-mounted automation module, located in the excavator cab, includes a main controller, an ignition controller, a positioning module, and a monitoring module. The remote data platform is connected to the vehicle automation module via a wireless communication network. It is used to receive pipeline protection schemes, generate electronic fences for construction areas without objections based on the approval results of the pipeline protection schemes, and generate ignition commands. It is also used to receive excavator positioning data sent by the positioning module, verify whether the positioning coordinates are within the electronic fence, and provide feedback to the ignition controller whether the ignition command is valid based on whether the excavator is within the electronic fence.

[0008] In the above technical solution, the main controller is a PLC or an embedded microprocessor; the positioning module is a GPS or Beidou module; and the ignition controller is a relay controlled by the main controller.

[0009] In the above technical solution, the remote data platform includes departmental review ports, process status database, data receiving and processing module, permission verification engine, remote control command issuance module, data storage module and accident information module.

[0010] In the above technical solution, the positioning module is located on the excavator's digging head.

[0011] Furthermore, the present invention also provides a method for monitoring excavator construction through the above-mentioned system, the method comprising: Based on the pipeline diagram and the actual pipeline conditions obtained on site, a pipeline protection plan is formulated and uploaded to the remote data platform; The pipeline protection plan is approved through the remote data platform. The remote data platform generates an electronic fence for the construction area without objection in the approval results and generates an ignition command; After the excavator's onboard automation module is powered on and connected to the network, it sends the positioning data from the positioning module to a remote data platform. The remote data platform verifies whether the excavation location is within the electronic fence based on the positioning data. If it is, it sends an ignition command to the ignition controller. After receiving the ignition command, the ignition controller sends an ignition command request to the remote data platform. After verification, the remote data platform sends an ignition execution command, and the ignition controller executes the excavator ignition operation. If the location is not within the electronic fence, it sends an ignition command to the ignition controller.

[0012] In the above technical solution, the actual pipeline information obtained on site includes pipeline coordinates, properties, usage status, and historical change data.

[0013] In the above technical solution, generating an electronic fence includes: Obtain the coordinates of the boundary key points of the fenced area and ensure that the coordinate system is consistent with the settings of the RTK device; The coordinates of the key points are transmitted to a remote data platform and connected to form a closed polygonal electronic fence, with the accuracy of the generated electronic fence being at the centimeter level.

[0014] In the above technical solution, if the positioning module is set in the cab, the remote data platform uses the positioning data to draw a circle with the positioning coordinates as the center and the construction radius as the radius as the excavation position, and verifies whether the circle is within the electronic fence; if the positioning module is set on the excavator head, the remote data platform uses the positioning coordinates of the positioning data as the excavation position, and verifies whether the positioning coordinates are within the electronic fence; when the remote data platform verifies that the positioning coordinates are not within the electronic fence, it also includes the step of triggering an audible and visual alarm and starting a countdown; if the positioning coordinates are still outside the electronic fence after the countdown ends, the ignition prohibition command is executed.

[0015] In the above technical solution, sending a non-ignition command to the ignition controller includes physically disconnecting the relay circuit of the remote ignition control device and shutting down the excavator.

[0016] In the above technical solution, the monitoring module continuously collects images from the cab and the surrounding environment of the excavator, and uploads the data to the remote data platform in real time.

[0017] Furthermore, if a pipeline accident occurs during excavator operation, the remote data platform will permanently save the image data corresponding to the time and location of the accident collected by the monitoring module.

[0018] Compared with the prior art, the present invention has the following advantages: 1. This invention achieves a rigid management mechanism of "no equipment start if the process is not completed" by forcibly linking the approval process with the excavator's ignition circuit, thus eliminating the risk of illegal operation without identifying pipelines or approving the construction plan.

[0019] 2. This invention has the ability to continuously monitor and dynamically judge during the construction process. It can identify abnormal behaviors such as illegal movement of excavators in real time, and automatically trigger alarms and remote power cut-off, forming a deeper level of safety protection closed loop.

[0020] 3. This invention integrates positioning information, environmental images, and driver's cab images to construct a traceable evidence chain with multi-source data association, providing a complete basis for accident analysis and effectively supporting post-accident liability determination and process review.

[0021] 4. This invention enables fully automated operation of the entire process from positioning verification and excavator ignition control to construction data recording, without the need for manual intervention, significantly improving the efficiency and reliability of pipeline protection management.

[0022] 5. This invention adopts a platform-based and modular design, decoupling the remote data platform from specific mechanical equipment. Through standardized communication protocols and control interfaces, it can be quickly integrated into various existing engineering management systems and construction machinery, possessing strong engineering adaptability.

[0024] Figure 2 This is a schematic diagram of the structure of the remote data platform of the present invention.

[0025] Figure 3 This is a flowchart of the excavator construction monitoring method based on pipeline protection according to the present invention. Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 1 As shown, the excavator construction monitoring system based on pipeline protection of this invention includes an on-board automation module and a remote data platform. The on-board automation module is integrated into the excavator cab and mainly includes a main controller, a 5G network module, an ignition controller, a positioning module, and a monitoring module. The main controller is connected to the 5G network module, ignition controller, monitoring module, and positioning module via signals. The main controller, as the core of the system, is implemented using a PLC or embedded microprocessor. The 5G network module is used to establish a real-time communication connection with the remote data platform. The ignition controller is connected in series to the excavator's original ignition circuit and receives commands from the main controller to physically switch the circuit on and off. The positioning module uses a GPS / BeiDou dual-mode receiver to continuously acquire the excavator's positioning coordinates. The monitoring module consists of a surround-view camera group, a camera inside the cab, and a data storage and compression unit, used to collect images of the excavator's surrounding environment and the driver's operating behavior, and to perform local storage and compression processing.

[0028] The positioning module of this invention can be installed inside the driver's cab. To obtain the accurate digging position of the excavator head, a circle drawn with the positioning coordinates of the positioning module as the center and the construction radius as the radius is used as the digging position. As a preferred embodiment, the positioning module can be installed on the excavator head, in which case the positioning coordinates of the positioning module are the digging position.

[0029] This invention employs an integrated "sensing-communication-control" architecture, enabling bidirectional data interaction between the vehicle-mounted terminal and a remote data platform via a 5G network. The main controller coordinates real-time location information collection, electronic fence verification, and ignition command judgment, forming a closed-loop control logic. The monitoring module continuously records multiple video feeds along with their corresponding time and location information during equipment operation, constructing a traceable digital archive of construction work, providing comprehensive data support for pipeline protection and accident tracing.

[0030] like Figure 2 As shown, the remote data platform of this invention serves as the "decision and control center" of the pipeline protection construction monitoring system. This platform comprises departmental review ports, a process status database, a data receiving and processing module, an access control engine, a remote control command issuance module, a data storage module, and an accident information storage module.

[0031] The platform employs a hybrid architecture combining client / server (C / S) and browser / server (B / S) architectures. Engineering managers approve pipeline exploration and relocation plans online through the approval portal (B / S), with process status recorded in the database in real time. The vehicle automation module (C / S client) maintains a persistent connection with the data receiving module via a 5G network, continuously uploading location data, images, and ignition requests. The core authorization engine proactively queries the process status database, compares vehicle coordinates with approved geofences, and generates either a "permit ignition" or "prohibit and remotely shut down" command, which is then executed by the remote control command issuing module. All monitoring data is categorized and stored in the data storage module, forming a traceable chain of evidence. After an accident, the accident information storage module can quickly retrieve and locate relevant evidence based on multiple keywords such as time and coordinates, enabling efficient post-accident analysis.

[0032] like Figure 3 As shown, the above-mentioned excavator construction monitoring system based on pipeline protection implements the following steps for excavator construction monitoring: Step S1: Upon arrival at the site, the project manager, based on the relevant pipeline diagrams provided in the tender documents, organizes design, construction, supervision, and relevant departments of the airport company to thoroughly verify the existing pipeline as-built documentation within the project scope, conduct on-site pipeline surveys, and thoroughly ascertain the pipeline coordinates, nature, usage status, and historical changes. Simultaneously, the construction team, based on the comprehensive briefing and the actual pipeline conditions on site, prepares a specific pipeline exploration and excavation plan, forming a pipeline protection (relocation) plan. This plan includes pipeline exploration and protection measures, emergency measures, a risk and hazard investigation list, and a safety assessment report. Then, step S2 is executed.

[0033] Step S2: The construction party submits the pipeline protection (or relocation) plan to the supervisor. The supervisor reviews the plan and submits it to the Engineering Management Department of the Infrastructure Department for review through the remote data platform. After the review is approved, it is submitted to the regional management department for approval through the remote data platform. After approval, it is submitted to the Safety Management Department for filing through the data platform. All the above review / approval operations are carried out through the review ports of the respective departments on the remote data platform. The review ports of each department obtain the data to be reviewed / approved from the process status database. After completion, step S3 is executed.

[0034] Step S3: The remote data platform generates a centimeter-level precision electronic fence based on the approval opinions of the regional management department. Specifically, if there are no objections, an electronic fence covering the entire construction area is generated; if there are objections for some areas, an electronic fence is generated for the undisputed construction areas (to prevent delays in the construction period). Simultaneously, after the safety management department approves the filing, the remote data platform generates an ignition command and then executes step S4.

[0035] In this embodiment, the specific process of generating the electronic fence is as follows: 1. Obtain the coordinates of key boundary points of the fenced area. Ensure that the coordinate system is consistent with the settings of the RTK (Real-Time Dynamic Carrier Phase Differential) device.

[0036] 2. Import these coordinate points into the remote data platform and connect them to form a closed polygonal electronic fence.

[0037] Electronic fence operation: 3. When the excavator head approaches or touches the boundary of the electronic fence, the vehicle automation module will issue a strong alarm in the form of sound and light to remind the operator, or remotely control the engine to shut down.

[0038] Step S4: After the excavator attempts to start, the on-board automation module is powered on and connected to the network. It sends a verification request to the data receiving and processing module of the remote data platform through the 5G network module, and then executes step S5.

[0039] Step S5: The positioning module acquires real-time positioning data and sends it to the data receiving and processing module of the remote data platform via the 5G network. The remote data platform's permission verification engine verifies whether the location is within the electronic fence based on the positioning data. If it is not within the electronic fence, the remote control command sending module sends a command to the positioning module to execute step S6. If it is within the electronic fence, the remote control command sending module sends a command to the ignition controller to execute step S8.

[0040] The present invention provides a method for a remote data platform to verify whether the excavation location is within the electronic fence based on the positioning data, depending on the installation location of the positioning module: If the positioning module is installed inside the driver's cab, the remote data platform uses the positioning data to draw a circle with the positioning coordinates as the center and the construction radius as the radius, as the excavation location, and verifies whether the circle is within the electronic fence. If the positioning module is installed on the excavator head, the remote data platform uses the positioning coordinates from the positioning data as the excavation location, and verifies whether the positioning coordinates are within the electronic fence. In step S6, the positioning module issues an audible and visual alarm and starts a 30-second countdown. After the countdown ends, step S7 is executed.

[0041] Step S7: The positioning module acquires real-time positioning data and sends it to the remote data platform. The remote data platform verifies whether the excavation location is within the electronic fence based on the positioning data. If it is not within the electronic fence, proceed to step S9; if it is within the electronic fence, proceed to step S8.

[0042] Step S8: The ignition controller sends an ignition command request to the remote data platform. If the remote data platform responds that ignition is possible, proceed to step S10. If the remote data platform responds that ignition is not possible, proceed to step S9. In step S9, the ignition controller's relay physically disconnects the circuit, shutting down the excavator, and then step S4 is executed.

[0043] Step S10: The excavator is officially started, the monitoring module is powered on and begins to collect images, the data is cached in a loop in the local storage card, and the image data is uploaded to the remote data platform in real time through the 5G network. Then, step S11 is executed.

[0044] The remote data platform determines the real-time position of the excavator head based on the real-time positioning data obtained by the positioning module. When the excavator head's position (excavation location) approaches or touches the boundary of the electronic fence, the vehicle automation module will issue a strong alarm in the form of sound and light to remind the operator, or remotely control the engine to shut down.

[0045] Step S11: The remote data platform data storage module classifies and operates according to whether a pipeline accident has occurred during construction. If an accident occurs, step S12 is executed; if no accident occurs, step S13 is executed.

[0046] Step S12: Based on the submitted pipeline accident time and location, the remote data platform uses the multi-condition composite query fast retrieval function to automatically locate relevant images and store them permanently in the accident analysis module of the platform for easy subsequent tracing and cause review of the accident. Then, step S13 is executed.

[0047] In step S13, the remote data platform categorizes and stores data such as images, time, and coordinates according to the project. After project acceptance, the data is archived and saved, and automatically deleted after one year.
