Embedded wireless concrete strength detector

Abstract

The invention discloses a pre-embedded wireless concrete strength detector, and the detector comprises a pre-embedded concrete strength detection node, a pre-embedded concrete strength detection gateway, a server and a client; the pre-embedded concrete strength detection node comprises a control module, a communication module, a temperature sensor, a metal detection sensor and a power supply module; the embedded concrete strength detection gateway comprises a communication module, a control module and a power supply module, and the embedded concrete strength detection node is connected with anexternal temperature sensor. The embedded wireless concrete strength detection is adopted to prevent damage to the surface structure of the concrete and detect the internal temperature of the concrete, the maturity of the concrete is measured by analyzing the change of the internal temperature of the concrete, and the strength of the concrete is calculated according to the maturity of the concrete, and the collected and calculated data is backed up in real time and uploaded to a server so as to facilitate later data check.

Description

technical field [0001] The invention relates to a strength detector, in particular to a pre-embedded wireless concrete strength detector, which belongs to the technical field of concrete detection equipment. Background technique [0002] With the continuous progress of the times, concrete, as the main construction material, is widely used in modern engineering, but in the process of engineering construction, due to the lack of concrete strength, frequent accidents occur, which not only affects the quality of construction, but also brings people's normal life. Life brings certain hazards. In the pouring process of large-area concrete, the internal temperature rise caused by the heat of hydration has a great impact on its life and quality. The existing temperature detection methods are ultrasonic rebound method, core drilling method, and pre-embedded method. The defect of ultrasonic rebound method can only measure the surface layer strength of concrete, and the internal situa...

[0002] With the continuous progress of the times, concrete, as the main construction material, is widely used in modern engineering, but in the process of engineering construction, due to the lack of concrete strength, frequent accidents occur, which not only affects the quality of construction, but also brings people's normal life. life brings certain hazards

In the pouring process of large-area concrete, the internal temperature rise caused by the heat of hydration has a great impact on its life and quality.

The existing temperature detection methods are ultrasonic rebound method, core drilling method, and pre-embedded method. The defect of ultrasonic rebound method can only measure the surface layer strength of concrete, and the internal situation of concrete cannot be known.

Disadvantages of the core drilling method The cost of detecting concrete is high and time-consuming, and the local damage to the concrete damages the surface integrity of the concrete. The existing pre-embedding method will pre-embed a temperature sensor before pouring the concrete. Leaving a wire out is inconvenient to use, the labor cost is high, and the strength of concrete cannot be calculated
