Pipeline inspection mesh ad hoc network solutionPipeline inspection mesh ad hoc network solutionoverviewAccording to the Central Intelligence Agency's "Yearbook of Facts Around the World". China's increasing length of natural gas pipelines; In 2018, it has increased to 76,000 km, which is twice as high as in 2010. The modern natural gas industry was developed on the basis of the city gas industry in the 19th century, and the process of gradually replacing city gas with natural gas was the process. Subsequently, natural gas fields were discovered one after another in various countries around the world, and the discovery of natural gas fields was the beginning of the modern natural gas industry in various countries, and natural gas gradually replaced artificial gas in cities. Natural gas pipelines can be divided into three categories: gas gathering pipelines (from the wellhead to the purification plant), gas transmission trunk lines (the purification plant exports to the city gate station or factory), and gas distribution pipelines (from the city gate station to the user). According to the data of China's National Bureau of Statistics, the production of artificial gas, the length of pipelines and the population of gas users within the city limits are declining year by year, and the length of pipelines and the population of liquefied petroleum gas are also declining year by year. The length of natural gas pipelines, the amount of gas supplied and the population of natural gas users are increasing year by year. With the increase of natural gas city pipelines year by year, the daily inspection and operation and maintenance of natural gas pipelines is also extremely large. Therefore, how to improve the efficiency of inspection, timely find pipeline damage points, and implement pipeline maintenance have also become issues of concern to relevant departments. Background descriptionChina's vast territory, complex terrain, oil and gas pipelines through highways, rivers, deserts, farmland, long lines, wide coverage, special geographical environment, through inspection to timely grasp the operation of the pipeline network and changes in the surrounding environment, to find pipeline defects and potential safety hazards, is the basis for ensuring the safe operation of the oil and gas pipeline network. However, the current situation of oil and gas pipeline inspection is mainly based on manual operation and inspection, which brings many potential safety hazards and difficulties to the current inspection of oil and gas pipelines. Heavy maintenance tasks of the pipeline network: Long-distance oil and gas pipelines often require "short, flat and fast" inspections, with short measurement cycles, heavy tasks and strict requirements; there are many weak links in the structure of the pipeline network itself, and it is easy to accelerate the aging of the pipeline due to the impact of the surrounding environment, such as untimely inspection and maintenance. Traditional manual inspection is not comprehensive: the pipeline covers a wide area, the geographical environment is complex, and it passes through uninhabited areas such as deserts, Gobi, forests, mountains, etc., and sometimes cannot be reached by personnel and measuring instruments. Secondary disasters are prone to occur in high-consequence areas: It is difficult to carry out high-frequency inspections for places that may affect hospitals, markets, schools and other places where it is difficult to evacuate people, as well as pipelines with flammable and explosive places such as chemical plants, gas stations, and oil depots, and sudden risks can only be responded to. Geological disasters are prone to occur in dangerous areas: most of the pipelines are distributed in the wild, especially in dangerous areas, it is difficult to achieve inspection management and supervision, and it is difficult to prevent and control natural and geological disasters, and the investigation of potential safety hazards is not timely. Pipeline leakage is highly hidden: Traditional oil and gas leakage detection relies on artificial sense of smell, ground instruments, surface vegetation observation and analysis, etc., which has limitations, and the danger is high if the inspection is not timely. Frequent oil theft: The complexity and concealment of pipeline distribution lead to illegal oil theft, which not only brings damage to pipelines, but also causes safety accidents caused by oil and gas leakage. Analysis of the current situationThe terrain is complex Inspections in mountainous areas are high-risk, and there are blind spots in areas that cannot be reached by manual field inspections. Manual inspections are inefficient There are many new projects, long patrol distance, large workload, low efficiency and high cost of walking inspection. Failure to respond to emergencies in a timely manner When an emergency occurs, personnel cannot quickly reach the designated place, and the emergency response efficiency is low. Lack of staff The operation and maintenance management departments of oil and gas pipelines generally have a phenomenon of attrition, serious aging of personnel, and high management costs. solutionANYMESH ad hoc network radio limit coverage point-to-point maximum communication distance of 160 kilometers, system bandwidth up to 100M, to achieve voice, video, image, message, positioning and other information real-time processing capabilities, and with the existing digital ultra-short wave, satellite communications to achieve horizontal integration and connectivity. The scheme design is as follows:
As shown in the figure above, the design of the entire consumer rescue command and communication scheme is divided into two parts. The airborne node part of the ad hoc network: the airborne node equipment of the ad hoc network carried by the UAV in the air and the individual soldier carrying node equipment of the ad hoc network can also be interconnected through mesh networking, and the communication distance from the general UAV to the ground detection personnel can reach more than 10-20KM. The main command center part: the emergency communication vehicle can build a communication link with the command center through 4G/5G and nearby communication base stations or through satellite signals. Equipment introduction
自组网机载台
In order to meet the application requirements of UAV swarm communication networking with limited load weight, Beijing Wanlantuo Communication Technology Co., Ltd. has developed the ANYMESH-SDR-A3 MIMO thin airborne mesh ad hoc network radio using OFDM technology and mobile ad hoc network technology, which can build a wireless IP mesh network temporarily, dynamically and quickly without relying on any basic communication facilities, with self-organization, self-recovery, high anti-indestructibility, and support multi-hop transmission of multimedia services such as data and video.

MESH Ad Hoc Network Portable Emergency Command Box Ad Hoc Network Three-screen Dispatching Console In aerospace, coal mine, energy and military industry, public security, government and enterprise, emergency rescue, field operation and command and dispatch and other industries, computers are required to collect and process data on site, and sometimes face huge computing and high-definition split-screen display viewing and processing, as well as the uncertainty of the work location, and also require strong outdoor endurance. Ordinary laptops don't have dustproof, drop-proof, and high-intensity handling.
Summary of the programThe deployment and application of the fully autonomous UAV inspection system not only greatly reduces the potential safety hazards and difficulties caused by manual inspection, but also significantly improves the inspection efficiency and precision of oil pipelines. Whether it is a regular survey of oil and gas pipelines, or an emergency inspection and handling of sudden accidents, especially in high-consequence areas that need to be strengthened, the system can achieve 7*24 hours of uninterrupted day and night protection. With the fully autonomous, visualized and intelligent inspection system solution, it has opened up a new path to solve the pain points and difficulties of oil and gas pipeline inspection, and promoted the intelligent management and upgrading of oil and gas pipelines, so as to achieve the overall optimization of safety, cost and efficiency.
