RFID underground markers are applied to Liuxi River crossing pipes

With the expansion of urban scale and the advancement of building construction, various pipelines supporting production and life are no longer suitable for laying on the surface. Considering the safety and reliability brought by burying pipelines underground, the Urban Planning Bureau is burying more and more pipelines underground. Although pipelines are no longer affected by ground and space buildings and harsh climate, it also brings new problems: how to accurately find underground pipelines.

Due to the limitations of urban underground space resources, contradictions have become increasingly prominent. First of all, it is common for the same line to run in parallel, and various types of pipelines are often buried in parallel along a single path. Secondly, according to the urban line management model, due to unclear on-site markings and the influence of the channel environment, the location of the problem point cannot be confirmed, causing the road to be accidentally dug and opened, making the troubleshooting efficiency low, and also causing negative social impacts.

       In order to change the above phenomenon, combined with the actual situation of Guangzhou City, the electronic identification technology of RFID + underground identification detector is used to solve and improve the current problems. At the same time, it changes the traditional mode of underground pipeline management and realizes the electronicization and informatization of operation management.

       The picture shows Fudi Street, Liuxi River, Baiyun District, Guangzhou City. A sewage pressure pipeline is buried. Starting from Fudi Street, the water passes through Liuxi River and ends at Jiannan Huancun Road. It is 600 meters long and has a total of 20 buried pipelines. Underground electronic markers.

       A sewage pressure pipeline is buried, starting from Helong 5th Road to Liuxi River, with a total length of 630 meters, and a total of 22 underground electronic markers are buried. The application of the RFID + underground identification detector system can effectively improve the efficiency of maintenance. Workers can quickly search for the location of pipelines, saving a lot of time for maintenance and emergency repairs.

       RFID electronic tags (radio frequency identification) have been widely used at home and abroad. It is a relatively mature identification technology and is widely used in electric power, chemical industry, steel, and cement where there are many large equipment, a large number of supporting auxiliary machines, a wide distribution range, and complex installation locations. The application is particularly common among enterprises.

       Through electronic identification technology based on RFID, the digital and information management of underground pipelines can be realized, as well as the supervision of the inspection rate of operators, the standardization process of operation management, the standardization and standardization of operation management terminology description, and the change of urban pipeline management. traditional model.

       The underground pipeline electronic identification system consists of two parts. One part is the research on electronic tags RFID, which ultimately realizes wireless data transmission and unlimited read/write functions and installs the electronic tags on the corresponding underground pipelines; the other part is the research on handheld terminal equipment. , using the wireless collection function to obtain on-site device information and maintain business data at the same time. The collected data is uploaded through the wireless communication network or office LAN, which avoids secondary maintenance of the data, reduces the workload, and avoids missed or mistaken recordings.

       The application of electronic identification technology based on radio frequency identification (RFID) in pipeline management can realize the rapid positioning of path channel information, effectively improve the level of backend digital and information management; realize the precise positioning of the opening of the well during fault repair, and improve the efficiency of fault repair; Standardize the pipeline management standardization process. The application of this system realizes data sharing between on-site data and information systems, which will greatly reduce the workload of maintenance personnel, improve daily work efficiency, and provide guarantee for safe line operation.
