Problems solved by technology

If the displacement suddenly accelerates and changes within the time interval between two measurements, the existing pull-rope displacement sensor will not be able to collect the change of the crack in time, and will not be able to report to the police in time, resulting in serious loss of personnel and property

Abstract

The invention discloses a self-triggering type wide-range displacement sensor. The self-triggering type wide-range displacement sensor comprises a multiturn potentiometer (1) and a thread spool (5) and further comprises a rotary encoder (2) and a transmission gear set (7), wherein the multiturn potentiometer (1) is coaxially connected with the thread spool (5), and the transmission gear set (7) comprises a driving gear and a driven gear. The driving gear is coaxially connected with the thread spool (5), the driven gear is coaxially connected with the rotary encoder (2), the rotary encoder (2) is connected with a data collecting and transmitting circuit (3) and is used for triggering the starting of the data collecting and transmitting circuit (3), the rotation of the thread spool (5) can drive the multiturn potentiometer (1) and the driving gear to rotate synchronously, and the rotation of the driven gear can drive the rotary encoder (2) to rotate synchronously. The self-triggering type wide-range displacement sensor can collect variable quantity caused when the displacement changes suddenly, the measuring precision is high, and the self-triggering type wide-range displacement sensor can be suitable for the field work environment.

Description

technical field [0001] The invention relates to a displacement sensor, in particular to a large-range displacement sensor with a trigger function. Background technique [0002] Drawstring displacement sensor, also known as drawstring sensor, is a new type of simple length displacement sensor with a wide range of uses, with compact structure, long measurement stroke, small installation space, high measurement accuracy, good reliability, long life and easy maintenance. Less advantages. In addition, the pull rope displacement sensor is easy to install and use, suitable for many dangerous applications, and widely used in measurement fields. [0003] The function of the drawstring displacement sensor is to convert the mechanical movement into an electrical signal that can be measured, recorded or transmitted. The pull-cord position sensor consists of a stretchable stainless steel wire wound around a hub which is connected to a precision rotary sensor which can be an incremental...
