Another aerospace product breaks foreign monopoly! Urban underground pipeline has domestic | 'ID card'

A few days ago, the digital signage developed by the Chinese Academy of Aerospace Science and Industry No. 203 broke the monopoly of foreign countries, and its annual output had broken 10,000 sets. This flashlight-sized signer installed electronic identification cards for each pipeline node of each underground pipeline.

Electronic marker

Urban underground pipelines with numerous human bodies are embedded with electronic markers.

There are a variety of underground pipelines, including water, electricity, heat, gas, and five major types of telecommunications fiber. Water, electricity, heat, and gas are just like the human energy supply. They meet the needs of all parties in the city. Communication fibers are like human nerves. The city is responsible for the transmission of various information. Underground pipe network as a hidden project, its maintenance and repair are all too much trouble. Due to changes in the landscape and changes in the ground markings, before the construction of the owner unit, it is difficult to find all the pipelines according to the previous construction drawings. The specific location, which brings great difficulties and risks to the construction of the pipeline.

The electronic marker is installed for the underground pipeline. Since the relative position of the electronic marker and the pipeline is fixed, it rarely changes with the landscape. The electronic marker detector is used to find the position of the electronic marker, and the position of the corresponding pipeline can then be found. It stores all the relevant information about the pipeline, including the material, type, ownership unit, laying time, etc. of the pipeline. With an electronic marker, it means that there is a pipeline ID card and the distribution of underground pipelines is well known. .

Electronic Markers as Passive Devices Facilitate Life Cycle Management of Pipe Networks

The electronic marker is buried in the ground, but there is no power supply. It is identified by radio frequency communication. The chip records the ID number. The ID is the underground pipeline ID and is used as the unique identification code. The electronic marker detector radiates the low frequency electromagnetic field and the marker is located in the electromagnetic field. Through the electromagnetic field, the power supply part is charged, so that the marker obtains energy, and the self-information is transmitted to the detector through the load modulation method.

The 'inconspicuous' electronic marker can be buried underground in municipal construction, and can also be installed on the top of the completed pipeline. The professional pipeline detection company conducts survey on underground pipelines and installs equipment at key nodes. In the pipe plugging, three-way, straight line pipe section 20 meters to 50 meters to install a marker, will not completely undermine the basic situation of the road. It is passive, non-polluting, long-term use, silently arranged in the elbow, valve river Crossover points, road crossing points and other important sites, waiting for the call of the electronic marker detector. In more than 30 years, as long as the electronic marker detector arrives, it will appear and reveal the truth.

Electronic Marker Solve the Most Urgent Problems in Urban Construction in Suzhou

Do not look at the small size of the electronic marker. Not long ago, it played an important role in the urban construction of Suzhou. At that time, the construction of the industrial park was underway. During the heavy rain, the water in the Suzhou Park was serious. Pipelines under construction disappeared in heavy rain. This can smash the on-site construction personnel. If the pipeline cannot be found, the implementation of follow-up projects cannot be carried out. Excavation can easily destroy the newly built pipeline. Once the explosion occurs, it will also cause even greater damage. At this crucial moment, the 203 Institute The on-site implementation personnel of the Smart Pipe Network team started their operations. In the turmoil, the 203 technicians, using the electronic marker, not only quickly and accurately positioned the pipeline, but also displayed the joyous 'drip' sound from the electronic marker detector. The site also displayed more than 20 attribute information of the pipelines from the type, diameter, pressure, flow direction and construction date of the pipeline, which provided strong data support for the subsequent construction. Through 20 minutes of pipeline positioning, Quickly solved the problem that the company could not find the location of various types of pipeline interfaces in the land for a week. It was difficult for construction companies to work for many days. The problem of construction work can be solved successfully.

Create the world's advanced underground pipe network management model

The electronic marker is only one of the dozen core products of the Smart Pipe Network built by 203. 'The goal of our network is to establish a pipe network management model that meets the city's own development positioning and to create a world-class advanced intelligent underground pipe system.' Liu Wei, the project leader, introduced that through the construction of the electronic signage system, the accuracy of underground pipeline data was raised to over 96%, the excavation accident rate was reduced by 45%-50%, and the pipeline maintenance and excavation ground area was reduced by 60%- 65%; Through the construction of the entire pipeline supervision system, the underground pipeline monitoring rate will reach 100%. In the event of an emergency, it will be able to quickly use the constructed emergency treatment system to rationally allocate the information resources of the pipeline management department and the ownership department. Resources and emergency repair resources; The use of intelligent pipeline network planning and analysis platform can realize regional pipeline space analysis, auxiliary functions, etc., and truly build an intelligent platform for planning management and decision-making; Promote pipeline information integrity, accuracy, centralized management, integration of underground pipeline information Resources, establish co-construction and sharing mechanisms, implement unified management.

According to designer Wang Xu, the 203 Institute is a core promotion unit of the “Wisdom Pipeline Network” and has profound technical accumulation and program reserves. The construction of the “Wisdom Pipeline Network” is a sunrise industry. At present, the country has no specific industry standards and norms. All products are tailor-made products based on market demand, satisfying different regions, different usage habits, and the use of different business objects. In the future, the 203 will focus on establishing the brand effect, and at the same time as an industry benchmark, it will fully absorb all industries. Demand, to break through the barriers of the inherent hardware and software systems, to provide users with top-level planning is continuous and effective, promote the implementation of a steady and reliable pipeline network intelligent construction and operation and maintenance programs.
