Dam long-term wireless temperature measurement system

Abstract

The invention discloses a dam long-term wireless temperature measurement system, which comprises a long-term temperature measurement hardware system, a data real-time acquisition, transmission and processing cloud platform system and a real-time query and analysis mobile and desktop interaction interface, and is characterized in that the long-term temperature measurement hardware system comprisesa concrete temperature sensor and a long-term temperature measurement cabinet, the concrete temperature sensor is arranged in a concrete bin, and a multi-channel wireless temperature measuring instrument is arranged in the long-term temperature measuring cabinet; the long-term temperature measuring cabinet is used for wirelessly transmitting temperature data acquired by the concrete temperature sensor to the data real-time acquisition, transmission and processing cloud platform system, and the data real-time acquisition, transmission and processing cloud platform system is used for acquiring,transmitting and processing the temperature data acquired by the concrete temperature sensor in real time, and wirelessly transmitting temperature data and processing results acquired by the concretetemperature sensor to the real-time query and analysis mobile and desktop interaction interface for display.

Description

technical field [0001] The invention relates to the field of real-time online temperature measurement of mass concrete, in particular to a long-term wireless temperature measurement system for a dam. Background technique [0002] The construction of extra-high arch dams or large-scale gravity dams has the characteristics of large warehouse surface area, complicated pouring process, difficult internal heat dissipation, and difficult maximum temperature control, which are prone to temperature cracks. These temperature cracks are easy to expand into deep cracks or even penetrating cracks under the action of external factors, endangering the safety of the dam body. Therefore, the temperature control and crack prevention of mass concrete is one of the most critical scientific and engineering issues during the construction of concrete dams. From the perspective of the mechanism of mass concrete temperature cracking, there are two main reasons: one is that the internal temperature...

AI Technical Summary

Problems solved by technology

[0005] (1) Traditional concrete dam monitoring only targets part of the dam section;

[0006] (2) Traditional temperature monitoring usually adopts manual on-site measurement and manual recording;

[0007] (3) The existing technology adopts the wired network mode, and the site layout and construction are difficult, and a large number of cables need to be used;

[0008] (4) The service life of the temperature measuring system in the prior art is short, and the life cycle from concrete pouring to the end of grouting is only a small part of the life cycle, and the original investment value of the temperature monitoring equipment cannot be fully utilized
