Abstract

The real-time multichannel gas flow monitoring method for gas-filled cable includes connecting the gas output of inflator, the gas passage of electronic flow meter and the gas inlets of the gas-filled cables; connecting the electronic flow meter electrically to the inflator and setting two platinum thermal resistors into each of the inflating gas passage; measuring the temperature difference of each platinum thermal resistor, amplifying the temperature difference signal, A / D converting, treating and calculating in the micro controller to obtain flow rate data; displaying and transmitting the flow rate data to the upper computer for real-time monitoring. The present invention can realize the remote monitoring and maintenance on cables.

Description

technical field [0001] The invention relates to a gas flow monitoring method, in particular to real-time monitoring of multi-channel gas flow of an inflatable cable, and belongs to the technical field of telecommunications. Background technique [0002] When the inflator inflates the cable, it is necessary to measure and track the gas flow of each cable, and judge whether the cable is leaking according to the flow rate, and perform maintenance. [0003] As far as the applicant knows, in the prior art, the maintenance of the inflator and cables is generally unattended, without digital processing of the inflation flow data of the cables, and the cables cannot be remotely monitored and maintained. Therefore, the real-time monitoring method of the multi-channel gas flow of the inflatable cable will be an important technical topic worthy of research. Contents of the invention [0004] The purpose of the present invention is to provide a real-time monitoring method for multi-ch...
