Description

Technical Field

[0001] This invention relates to the field of underground cable pipeline protection technology, and in particular to a cable pipeline anti-mis-digation identification system based on laser marking and electronic data. Background Technology

[0002] In the construction and subsequent maintenance of municipal pipeline projects such as power and telecommunications, it is crucial to accurately identify the ownership, voltage level, and laying time of underground cable pipelines. Currently, the identification of cable protection pipes (such as MPP pipes, CPVC pipes, PE pipes, etc.) mainly adopts traditional methods such as spraying text, hanging nameplates, or relying on as-built drawings, but the pipe body itself lacks permanent, machine-readable identification marks.

[0003] The existing technology has the following drawbacks: First, the markings are easily damaged: the sprayed markings are easily blurred due to construction friction, soil corrosion and ultraviolet aging; the hanging nameplates may fall off or be damaged during the laying or backfilling process.

[0004] Second, information isolation: the identification information is disconnected from the back-end database, and maintenance personnel cannot quickly and accurately obtain the complete attributes of the cable (such as its customer, real-time status, and precise coordinates) on site.

[0005] Third, the positioning is rough: it can only locate the general area and cannot accurately locate the specific pipe, which can easily lead to misjudgment, especially when multiple pipes are laid in parallel.

[0006] Fourth, difficulty in tracing: Once an accident occurs, such as the wrong cable being dug due to unclear identification of the problematic line, it is difficult to quickly trace the original data, construction party and acceptance information when the pipeline was laid, resulting in unclear determination of responsibility and huge losses.

[0007] In view of this, it is particularly important to provide a comprehensive identification system that is integrated with the pipe material, durable, machine-readable, and can be linked with electronic data systems to achieve accurate identification of cable pipelines, prevention of accidental excavation, and rapid traceability. Summary of the Invention

[0008] The purpose of this invention is to address the problems of existing cable protection pipe marking methods being easily damaged, having limited information, being inconvenient to query, and having inaccurate positioning, which leads to the high risk of accidental excavation and damage to major cables during construction and maintenance. Therefore, this invention proposes a cable pipeline anti-accidental excavation identification system based on laser marking and electronic data.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: A cable pipeline anti-mis-digation identification system based on laser marking and electronic data includes a cable protection pipe, electronic data identification points, and a mobile terminal. The outer wall of the cable protection pipe is pre-embedded with a permanent laser-engraved QR code. The electronic data identification points are set at key nodes along the cable path and have built-in RFID or NFC chips. The mobile terminal is a smartphone or dedicated PDA used by construction or maintenance personnel. The mobile terminal has a mini-program or APP installed and can scan the laser-engraved QR code and read the electronic data identification points, and interact with a cloud database.

[0010] As a further description of the above technical solution: The cable protection pipe is made of one of the following materials: MPP, CPVC, PE, or BWFRP.

[0011] As a further description of the above technical solution: The cable protection pipe has an identification area for carrying laser-engraved QR codes every 1 to 1.5 meters along the axial direction of its outer wall.

[0012] As a further description of the above technical solution: The laser-engraved QR code uses laser engraving technology to directly etch the QR code onto the marking area of ​​the cable protection pipe. The laser engraving parameters are adjusted according to the pipe material to ensure that the laser engraving is clear, of appropriate depth, and does not damage the strength of the pipe itself.

[0013] As a further description of the above technical solution: The electronic data identification points are equipped with RFID or NFC chips that are corrosion-resistant and weather-resistant. They store summary key information related to the pipeline section.

[0014] As a further description of the above technical solution: The key nodes of the cable route are utility poles, manholes, junction boxes, or branch boxes.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. This invention provides dual protection from road section overview to precise identification of individual pipes, which greatly reduces the risk of accidental excavation caused by unclear markings and unknown information, and achieves the function of preventing accidental excavation and accidents, avoiding major economic losses and safety accidents.

[0016] 2. In this invention, the label is durable and long-lasting. The laser-engraved QR code is integrated with the pipe material, making it wear-resistant, corrosion-resistant, and anti-aging. Its service life matches that of the pipe material itself, overcoming the shortcomings of traditional spraying and nameplates that are easily damaged.

[0017] 3. In this invention, the information capacity is large and real-time. By linking to the cloud database through QR codes, massive amounts of information can be stored and updated, such as coordinates, customers, cable parameters, construction files, or maintenance history, which are no longer isolated and outdated static information.

[0018] 4. In this invention, the positioning is precise. By combining the road segment positioning of electronic markers and the individual identification of pipe QR codes, centimeter-level accurate positioning can be achieved, which is particularly suitable for complex pipe laying projects with multiple pipes running side by side.

[0019] 5. In this invention, construction and maintenance are convenient. All data entry, query and update operations can be completed using ordinary smartphones and mini programs without the need to carry special and complicated equipment, which reduces the threshold and cost of use.

[0020] 6. This invention improves management efficiency and traceability, realizes full life-cycle digital management of cable pipeline assets, and allows accident responsibility to be clearly traced back to the source of laying, thereby improving the modernization level of municipal facility management.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-3This invention provides a technical solution: a cable pipeline anti-mis-digation identification system based on laser marking and electronic data, including a cable protection pipe 1, an electronic data identification point 2, and a mobile terminal 3. The outer wall of the cable protection pipe 1 is pre-fabricated with a permanent laser-engraved QR code 1a. The electronic data identification point 2 is set at key nodes of the cable path and has a built-in RFID or NFC chip. The mobile terminal 3 is a smartphone or dedicated PDA used by construction or maintenance personnel. The mobile terminal 3 has a mini-program or APP installed. The mobile terminal 3 can scan the laser-engraved QR code 1a and read the electronic data identification point 2, and interact with a cloud database.

[0025] Specifically, such as Figure 1 and Figure 2 As shown, the cable protection pipe 1 is made of one of the following materials: MPP (modified polypropylene), CPVC (chlorinated polyvinyl chloride), PE (polyethylene), or BWFRP (glass fiber reinforced plastic), which gives the cable protection pipe 1 characteristics such as high temperature resistance, corrosion resistance, and impact resistance.

[0026] Specifically, such as Figure 1 and Figure 2 As shown, a marking area for carrying a laser-engraved QR code 1a is provided every 1 to 1.5 meters along the axial direction of the outer wall of the cable protection pipe 1. This marking area can be visually indicated by slight grooves or different colored coatings.

[0027] Meanwhile, the laser-engraved QR code 1a uses laser engraving technology to directly etch the QR code onto the marking area of ​​the cable protection pipe 1. The laser engraving working parameters (such as power, speed, and frequency) are adjusted according to the pipe material (MPP, CPVC, PE, BWFRP) to ensure that the laser engraving is clear, the depth is appropriate (e.g., 0.1-0.3mm), and does not damage the strength of the pipe itself.

[0028] Among them, the QR code information of laser-engraved QR code 1a is a unique code, which can be used as a key to associate the detailed file of this section of pipe in the background database.

[0029] Specifically, such as Figure 1 and Figure 2 As shown, the key nodes of the cable path are utility poles, manholes, junction boxes or branch boxes. In actual use, the above-mentioned centralized or other intermediate cable equipment can be selected as key nodes. In this application, utility poles are preferred as key nodes of the cable path. The electronic data identification point 2 is fixedly installed in the starting pole, ending pole or manhole between two adjacent utility poles (the pole distance is usually 50-60 meters, but the maintenance interval can be reduced to 5-6 meters for key nodes).

[0030] Among them, the built-in RFID or NFC chip of the electronic data identification point 2 is a corrosion-resistant and weather-resistant RFID tag or NFC chip module. It stores summary key information related to the pipeline section, such as: road section number, pipeline direction, number of cable protection pipes contained, or emergency contact person, etc.

[0031] Interactive Function: On-site personnel first use mobile terminal 3 to read electronic data marker 2. The mini-program automatically locates the road segment and can load a detailed list of all pipelines in that segment from the cloud. Then, by scanning the laser-engraved QR code 1a on any cable protection pipe 1, they can accurately match and retrieve all the data of that pipe from the list.

[0032] Specifically, such as Figure 1-3 As shown, the data association and management process (mini-program / app function): Laying Period (Data Entry): Before pipeline laying, use a mobile terminal 3 to scan the laser-engraved QR code 1a on the cable protection pipe 1, and simultaneously enter or automatically obtain (via the terminal's GPS) the precise latitude and longitude, burial depth, laying date, construction team, and cable attributes (voltage level, customer, line name, etc.) of the pipeline laying. This data is uploaded to the cloud database and permanently bound to the laser-engraved QR code 1a. At the same time, this pipeline information is associated with the electronic data identification point 2 of its location.

[0033] Maintenance / Repair Period (Data Query): a. Road Section Overview: Upon arrival at the site, personnel will first read the electronic data marker point 2 at the utility pole to quickly understand the pipeline layout of the road section.

[0034] b. Precise identification: At the point where excavation or maintenance is required, scan the laser-engraved QR code 1a on the exposed or excavated cable protection pipe 1.

[0035] c. Information retrieval: The mini-program immediately retrieves full-dimensional information about the pipeline from the cloud (including the location information at the time of laying, which can be used to compare with the current device's GPS positioning) and issues audio and visual prompts (such as "Important customer trunk line, excavation is strictly prohibited!" or "Communication optical cable, handle with care").

[0036] d. Data update: After maintenance, the maintenance record can be updated by scanning the laser-engraved QR code 1a.

[0037] Example 1: Application in MPP power protection pipe Pipe material: Orange-red MPP power pipe (standard type) with an outer diameter of 110mm and a wall thickness of 6mm is selected, with a length of 6 meters / piece.

[0038] Laser marking: On the outer wall of the pipe, a flat surface is selected every 1.2 meters as the marking area. Using a fiber laser marking machine, with the power set to 20W and the scanning speed at 800mm / s, a 10mm×10mm QR code is marked in this area. After marking, the QR code is clear and has a slight concave feel to the touch.

[0039] Electronic Identification Points: A waterproof and tamper-proof UHF RFID tag is installed on the utility poles at the beginning and end of the MPP pipe laying path.

[0040] Data Operation: During installation, workers use a mobile app to scan RFID tags and bind them to the "10kV Industrial Park Branch Line #3 to #4 pole" section. Then, they scan the QR code on each MPP pipe and enter the information: "Cable voltage 10kV, Customer: XX Data Center, Laying depth 1.2 meters, Coordinates: (XXX, YYY)". During maintenance, personnel read the RFID tags on the poles to obtain the section information, and then scan the QR code on any MPP pipe to confirm its customer as an "Important Data Center." Careful operation is required.

[0041] Example 2: Application in BWFRP cable protection conduit (for cable mounting on poles) Pipe material: BWFRP pipe with an outer diameter of 200mm is selected for protective sleeves on cable poles.

[0042] Laser engraving: Since the surface of BWFRP is made of resin glass fiber, the laser parameters are adjusted (such as reducing power and increasing the number of scans) to engrave a total of 4 QR codes at both ends and the middle of the pipe, ensuring that at least one QR code is easy to scan after installation.

[0043] Electronic Identification Point: An NFC chip is installed under the crossarm of the utility pole.

[0044] Data Operation: Before pole installation, scan the NFC chip and the laser-engraved QR code 1a on the cable protection tube 1 to bind them, and enter the information: "Function: Cable pole protection, Line: XX main line, Installation height: 8 meters from the ground". During pole maintenance, scanning the NFC chip or the laser-engraved QR code 1a on the cable protection tube 1 can quickly confirm the attributes of the cable inside the protection tube.

[0045] Example 3: Application in PE cable protection pipes (for municipal pipeline installation) Pipe material: 200mm outer diameter, SDR17 series (nominal pressure 1.0Mpa) black PE pipe with blue stripes on the pipe body.

[0046] Laser engraving: Engrave the QR code 1a in the black area next to the blue bar for better contrast. Set the spacing to 1 meter.

[0047] Electronic Identification Points: Moisture-proof NFC tags are installed on the inner wall of each manhole in municipal pipeline projects.

[0048] Data Operation: During installation, data is associated on a per-well basis. The manhole cover is opened, the NFC tag inside the manhole is read, and then the laser-engraved QR code 1a of all PE pipes placed in that manhole is scanned, thus classifying them for management by that manhole. This enables "pipe locating by manhole," precisely pinpointing each pipe.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
