Problems solved by technology

[0010] Aiming at the deficiencies of the prior art, the present invention provides an outdoor online monitoring tension sensor, which is powered by solar cells, has the characteristics of waterproof, anti-collision, low power consumption, etc., and can be installed on ropes and cables to realize long-term online monitoring functions The advantage of providing data support for the operation and health online monitoring of railways, electric power, bridges, and highways solves the problem that the existing side pressure tension sensors need to rely on external power sources when they work, and their protection characteristics are poor. The working method is handheld The method can not be applied to occasions where long-term real-time monitoring of tension is required outdoors

Abstract

The invention relates to the technical field of mechanical sensors, and discloses an outdoor online monitoring tension sensor which comprises a hollow cylinder structure composed of an upper shell and a lower shell, the upper shell and the lower shell are mutually clamped, the top of the upper shell is fixedly connected with a solar cell panel, and the top of the solar cell panel is fixedly connected with a tension sensor. A pressure sensor used for monitoring the stress state of the rope is arranged in the middle of the interior of the lower shell. The device is powered by a solar cell, can work outdoors for a long time, has a good protection characteristic, is filled with waterproof glue, is internally provided with a drainage hole, can tolerate a rainfall environment for a long time, is provided with a wireless module, and can send data obtained by testing to a terminal through a wireless communication protocol for online real-time monitoring. According to the outdoor online monitoring tension sensor, the fixing points at the two ends of the shell are ingeniously utilized, the three-point lateral pressure measuring principle of the fixing points at the two ends of the shell and the measuring points of the pressure sensor is formed, the structure is small and exquisite, and installation is convenient.

Description

technical field [0001] The invention relates to the technical field of mechanical sensors, in particular to an outdoor online monitoring tension sensor. Background technique [0002] In the fields of railways, electric power, bridges, highways, mines, etc., it is often necessary to lay steel cables, ropes, and cables outdoors for long distances for structural load bearing, structural reinforcement, or signal transmission. The tension of these ropes is the most critical for construction. A drastic change in the tension of the rope will often cause adverse effects on the system, so the measurement of the tension of the rope is particularly critical. Most of the tension measuring instruments currently on the market are hand-held devices, which can only meet the needs of regular tension testing. Due to the influence of weather and natural disasters, the ropes working outdoors are prone to damage and failure, which affects the normal operation of railways, electricity, bridges, ...
