Self-power built-in wireless data transmission reinforcement meter for detection

Abstract

The present invention discloses a self-power built-in reinforcement meter sensor for structure detection. The self-power built-in reinforcement meter sensor comprises a protective cover, an inertia generator arranged in the protective cover, a reinforcement meter sensor, an anchor bar, a wireless module and other function modules. The self-power built-in wireless data transmission reinforcement meter is able to realize the self power of the system, measure stress parameters of the reinforcing steel bars in the structure by the reinforcement meter, and transmit measured data to an external receiver through the wireless module; the system is able to perform self power with the structure displacement, the generated electric quantity may be supplied to the system for normal work and may charge a storage battery. According to the invention, the structure design is reasonable, the processing, the manufacture, the installation and the arrangement are convenient, the usage operation is simple, the measured data is real and reliable, and there are not provided wires to influence the measurement data, so that data may be truly and accurately transmitted to a terminal system for data processing, and the problems are effectively solved that the traditional measurement mode depends on the wires and the influences such as signal attenuation, signal interference and the like are brought by the wires.

Description

technical field [0001] The invention relates to a built-in speed sensor, in particular to a built-in wireless data transmission steel bar meter used for structure detection and capable of autonomous power supply. Background technique [0002] Nowadays, with the construction of infrastructure such as transportation, the role of high-pier and long-span structures in economic development is becoming more and more important. The detection of in-service structures has also become an indispensable method and means for judging structural performance. The traditional detection method relies on pre-embedding the steel bar meter and laying the wires to detect the internal conditions of the structure; due to the pre-branching of the wires, it is easy to cause damage to the steel bar meter wires due to factors such as construction during the actual erection of the formwork and concrete pouring, causing damage to the steel bar meter. And because the wire is permanently embedded, in pract...
