Problems solved by technology

Thin cables are wound side by side when they are unwound or retrieved from the cylindrical reel. Since the settlement needs to be converted by the formula, the circumference of the cylindrical reel needs to be fixed, and when the measurement depth is deep enough, the required cable length will also be Longer, the guide wheel and the cable may also slide relative to each other, making the measurement error larger

Embodiment 1

[0051] Such as figure 1 As shown, this embodiment provides a fully automatic high-precision layered sedimentation instrument, including a transmission device, a limit device, a control circuit, a grating speed sensor, a grating measuring ruler 1, a conductor probe 2, a sedimentation tube 3 and a magnetic sedimentation ring 4 , and; wherein, the grating measuring ruler 1 is connected with the transmission device, sinks into the settling tube 3 through the limit device and is connected with the conductor probe 2; the limit device is detachably installed at the end of the settling tube 3, for ensuring that the grating measuring The ruler 1 passes but the conductor probe 2 cannot pass, so that the conductor probe 2 is lowered from the same position every time; the magnetic settling ring 4 is set on the settling tube 3; the control circuit is electrically connected with the transmission device and the conductor probe 2, and the grating speed sensor is set On the limit device and ar...

Embodiment 2

[0078] Such as Image 6 As shown, this embodiment provides a control method for a fully automatic high-precision layered sedimentation instrument, including the following steps:

[0079] S1: The control circuit receives the measurement start command input by the user, and controls the transmission device to start working. The transmission device drives the grating measuring ruler 1 to drive the conductor probe 2 to be lowered from the limit device in the settling tube 3 at a certain speed.

[0080] Among them, before step S1, it is necessary to drill layered settling holes, then set the magnetic settling ring 4 on the settling tube 3, use the limit pipe collar to limit the magnetic settling ring 4 to the preset position, and start measuring the specified time period Before (as 1 month), the settling pipe 3 is lowered and buried in the soil, and the length of 10-20 cm is reserved above the ground.

[0081] Wherein, the embedding work of the settling pipe 3 is completed before ...

Abstract

The invention discloses a fully automatic high-precision layered sedimentation instrument and its control method. The layered sedimentation instrument includes a transmission device, a limit device, a control circuit, a grating speed sensor, a grating measuring ruler, a conductor probe, a sedimentation tube and a magnetic sedimentation device. ring; through the grating speed sensor and grating measuring ruler, measure the instantaneous speed of the conductor probe lowered in real time, and record the moment when the conductor probe passes through the magnetic settling ring under the action of electromagnetic induction to generate an induced current in real time, and automatically calculate each magnetic settling through the control circuit The depth of the ring, fully automatic determination of the position of the magnetic settling ring, makes the measurement of the position of the magnetic settling ring more accurate, and the use of a grating speed sensor and a grating ruler to measure the instantaneous speed of the conductor probe lowering can reduce the measurement error.

Description

technical field [0001] The invention relates to the technical field of civil engineering instrument monitoring, and more specifically, to a fully automatic high-precision layered settlement instrument and a control method thereof. Background technique [0002] At present, the general layered settlement monitoring mainly adopts the electromagnetic layered settlement instrument. According to the principle of electromagnetic induction, the magnetic settlement ring is placed at a specific position on the settlement tube through the drill hole. When the electromagnetic probe passes through the magnetic ring, the monitoring The instrument sends out an audible and visual alarm, and then manually reads the reading of the soft ruler. This kind of monitoring instrument is easy to use and is suitable for various field environments, but there is no fixed device on the wire reel, and generally at least two people are required to operate it, and one person will put it down and the other p...
