Problems solved by technology
[0004] In the tracking and positioning of pigs, the performance of the magnetic field transmitter is directly related to the safety of the pipeline. Among them, the signal strength and attenuation characteristics of the magnetic field transmitter are the most critical technical indicators. If the signal strength of the magnetic field transmitter is not enough and If the pig runs too fast, the magnetic signal receiver will not be able to receive the signal from the magnetic field transmitter, resulting in the pig being lost. At this time, if the pig is stuck, the position of the pig cannot be located. Therefore, it is very important to quantitatively test the signal strength and attenuation characteristics of the magnetic field transmitter. However, there is no such indicator so far. The method and equipment for quantitative testing make it urgently necessary to carry out a method and equipment for quantitative testing of this indicator

Description
technical field [0001] The invention relates to the field of pig positioning and tracking, in particular to a signal strength detection device for a magnetic field transmitter for tracking and positioning of a pig. Background technique [0002] The existing pig tracking and positioning products mainly use the principles of acoustics, machinery, radioactivity, electromagnetic and permanent magnetism to track and locate the pigs. Since the technology of electromagnetic tracking and positioning equipment is gradually mature, it has the advantage of high positioning accuracy. application mainstream. [0003] The existing electromagnetic tracking and positioning equipment usually consists of two parts: magnetic field emission and magnetic signal reception. The magnetic field transmitter is installed on the pig, and while moving with the pig, it emits electromagnetic signals for tracking and positioning. Outside the pipeline, it receives signals from inside the pipeline to identi...
