Abstract

The invention discloses a non-inserting acoustic wave type pigging pass indicator monitoring device and method and belongs to the technical field of automation. An acoustic wave sensor contacts with a pipeline and is connected with a signal conversion circuit which is connected with a pigging pass indicator host, an AD converter, a data processing module, a display output module and a data teletransmission module of the pigging pass indicator host are connected mutually. The non-inserting acoustic wave type pigging pass indicator monitoring device has the advantages that compared with a mechanical or electronic pigging pass indicator, the non-inserting acoustic wave type pigging pass indicator has the advantages of being convenient to mount, needless of pipeline tapping and needless of mounting a signal transmitter on a pipe cleaner. The monitoring device is uniform with the mechanical or electronic pigging pass indicator in monitoring result and low in cost.

Description

technical field [0001] The invention relates to a non-insertion acoustic wave pigging indicator monitoring device and a monitoring method, which belong to the technical field of automation. Background technique [0002] At present, the monitoring work of the pigging process mainly adopts mechanical pigging indicator or electronic pigging indicator. Among them, such as figure 1 As shown, the mechanical pigging indicator 2 (2 is the pig, delete) needs to open a hole in the pipeline 1, which is easy to fail and cause gas leakage, and can only be installed on the entry and exit spherical cylinder; the electronic pigging pass The indicator needs to install a signal transmitter after rebuilding the pig, and needs to install a signal receiver along the pigging route, which is expensive. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a non-inserting acoustic wave pigging indicator monitoring device and a ...
