Use the advantages of new radio frequency (RFID) technology and cooperate with geographic information system (GIS) technology to complete the collection and digitization of urban municipal pipeline resource data, and establish a service for the scientific management of urban underground pipeline network, planning and planning, and auxiliary resolution plans. Municipal pipeline resource management system.
The application of RFID in underground pipelines indicates that the management is an important part of the urban infrastructure, and it is an important basic information for urban planning and construction. Urban underground pipelines include water supply, drainage (rainwater, sewage), gas (gas, natural gas, liquefied petroleum gas), telecommunications, electricity, heating, industrial pipelines and other categories. They are burdened with the task of transmitting information or transporting media. The material foundation on which survival and development depend is called the “lifeline” of the city.
The management of urban underground pipelines is the most important part of the construction and management of urban infrastructure equipment. Most of the pipeline network diagrams now use the constructions on the ground as references to locate pipelines. Because of the acceleration of urban construction, the increase in construction and demolition, the expansion of roads and other factors, the change and disappearance of the original reference objects, the quasi-confirmation of the pipeline The position has a great influence. Various raw material pipelines such as water supply, electricity, communication, and gas in the municipal pipeline network are often congested together, and it is often difficult to recognize certain types of pipelines, which puts forward higher requirements for daily maintenance and handling. Traditional metal probes are disturbed by stray currents and geological environment during the operation process, and the exploration power is often unstable. The traditional exploration methods only stay at the stage of confirming the orientation. Regarding the detailed characteristics of the explored pipelines, For example, during the construction period, construction units, pipe materials, etc., also need to consult a lot of drawings and materials, especially for the long-lasting pipelines. It is often difficult to inquire materials, and even the materials are lost, which makes the maintenance of the pipeline difficult.
Based on the above reasons, the new underground pipeline positioning and inspection maintenance system uses RFID as the management method. It is an exploration and data processing system that can satisfy pipeline quasi-confirmation and reflect pipeline practice information from an above-ground non-excavation method. Well deal with the problems encountered in the maintenance and construction of traditional pipelines.
The underground pipeline positioning and inspection system, as a new technique for underground equipment positioning and information recording and query, can effectively improve the maintenance level of the pipeline network and increase the gold content of the underground pipeline network properties. Especially with regard to improving the speed of emergency repairs, the promotion and application of PE pipelines, and the reduction of maintenance costs are of great assistance. To prevent the large-scale excavation of roads in order to find pipelines to face the impact of residents’ lives, it also ensures the accurate identification and safe handling of urban underground pipelines. In addition, it can also establish a resource library for maintenance personnel to maintain and repair underground pipelines.
The underground pipeline positioning and inspection system includes RFID tags, readers and antennas to read the pipeline diameter, pressure, tee, elbow number information, so that the entire underground pipeline can be traced, and the application can complete the navigation and inspection pipeline The function. Obtain a variety of relevant information about underground pipelines, including spatial orientation, scale standards, raw materials, transmission materials, transmission status, corrosion status, location of leaks, size and other health information of the pipeline itself.
Active data collection
RFID tags are embedded in the pipelines, and the characteristic information of some pipeline equipment is stored in the tags, which is convenient for information processing. The tag is waterproof, antimagnetic, high temperature resistant, and has little environmental impact, suitable for harsh environments; passive and touch-free operation, the RFID reader is penetrating and easy to use; it has a fast reading speed and can handle multiple electronic tags together , Efficient and accurate, and the operation process is transparent in real time.
Quick search for accurate confirmation position
Accurately confirm the location of underground equipment, and can quickly find and intelligently read the information of underground equipment, reduce the rate of excavation incidents and reduce costs, improve the power of emergency construction, and effectively maintain the underground equipment.
