Embodiment

[0027] When the original connection method cannot realize the signal transmission due to the transformation and replacement of the steel tower, disconnect the signal between the operation platform and the plate at the bottom of the river. Then connect the signal terminal of the winch of the control console to the port of the underwater plate, and connect it to the signal ground port of the console as the ground terminal of the signal. Then connect the signal line on the auxiliary cable, and connect the connecting signal line on the auxiliary cable to the signal terminal of the console as the integrated signal input terminal. After that, connect the output line of the lead fish LZX-1 signal tube to the front end of the insulator of the auxiliary cable, so that the integrated underwater signal is transmitted to the signal terminal of the console through the auxiliary cable. And connect the two ends of the lead fish suspension cable insulator at the same time, remove the insulati...

Abstract

The invention discloses a solution for the failure of the comprehensive signal transmission of a hydrological cableway. The solution for the failure of the comprehensive signal transmission of a hydrological cableway comprises the following steps: the signal input end of a control console and the input end of a river bottom pole plate are disconnected; the input end of a river bottom pole plate ofthe original control console is connected to a cableway winch; the signal input end of the control console is connected to an auxiliary cable; the output line of an LZX-1 signal tube of an elliptic-type weight is connected to the front end of an insulator of the auxiliary cable; the connection mode of an insulator of an elliptic-type weight suspension cable is changed; and a knife switch is arranged. By altering the equipment connection mode and constructing a new signal transmission circuit, the invention conveniently solves the problem that signals are lost and comprehensive signals fail tobe transmitted back because the potential difference between both ends cannot meet the requirement of signal transmission due to over-low ground resistance caused by the alteration or replacement ofa steel tower.

Description

technical field [0001] The invention relates to the technical field of cableway speed measurement, in particular to a solution to the failure of hydrological cableway integrated signal transmission. Background technique [0002] The hydrological cableway system is the most important test method for hydrological tests. After a series of technical updates of the friction clutch system, electromagnetic clutch system, and the frequency conversion semi-automatic cableway system used until now, the technology is becoming more and more mature, and the use and control are more convenient and accurate. The signal system has also been upgraded from the initial electric bell double signal (river bottom, flow velocity) to carrier-type three-signal (water surface, river bottom, flow velocity) signal tube, and the signal transmission method has also been upgraded from DC current signal mode to carrier voltage mode. Reliability has been greatly improved. However, the problem of poor sign...
