Abstract

The invention discloses a pipeline interior detector ground marking system with a function of Internet of things. The pipeline interior detector ground marking system with the function of Internet ofthings is characterized by comprising a microprocessor, an electromagnetic signal receiving and processing module, a static magnetic field signal receiving and processing module, a beidou / GPS dual-mode positioning time service module, a bluetooth module, an NBIoT module and a storage module. The electromagnetic signal receiving and processing module, the static magnetic field signal receiving andprocessing module, the beidou / GPS dual-mode positioning time service module, the bluetooth module, the NBIoT module and the storage module are connected with the microprocessor. The pipeline interiordetector ground marking system with the function of Internet of things can be applied to pipeline interior detector systems based on the electromagnetic wave principle and the static magnetic field principle at the same time. The signal processing portion adopts a real-time FFT calculation mode, and therefore the pipeline interior detector ground marking system has the higher measurement accuracyand fulfills a function that a transmitter runs to the position under the marking system and is triggered. Due to the utilization of the bluetooth module and the NBIoT module, the pipeline interior detector ground marking system has a function of wireless data communication and the function of Internet of things, and facilitates practical engineering application.

Description

technical field [0001] The invention belongs to the field of in-pipeline detection, and in particular relates to a ground marking system for an in-pipeline detector that is used in conjunction with an in-pipeline detector and has an Internet of Things function, which is applied to long-distance pipeline transportation. Background technique [0002] Compared with other transportation methods, pipeline transportation has unique advantages. With the application of pipeline transportation more and more widely, its safe operation has also attracted people's attention. Regular internal inspection of pipelines is an effective way to ensure pipeline safety. s method. [0003] According to the location of the pipeline inspection equipment, pipeline inspection can be divided into two categories: in-pipeline inspection and out-pipeline inspection. Among them, the in-pipeline detection method can continuously detect hundreds of kilometers of pipelines. It can not only detect internal d...

Problems solved by technology

[0006] 1) Traditional ground marking systems are mostly designed for one type of in-line detector, that is, one set of ground marking systems can only be used with one set of internal detectors, and cannot be mixed with each other;

[0007] 2) The traditional ground marking system mostly uses the serial port mode for data transmission, and the communication rate of the serial port severely limits the data upload rate of the entire system. It can be said that the serial port communication is the speed bottleneck of the data communication environment;

[0008] 3) In the process of pipeline detection, the operator must follow the movement of the detector in the pipeline to observe the working conditions of the ground marking system along the line one by one, so as to confirm whether the detector in the pipeline passes through the marking system. The workload of this work is very heavy Large, waste of human, material and financial resources
