Embodiment Construction

[0025] figure 2 is a block diagram of a multi-channel wireless measurement system with individual sensor interface modules according to the present invention.

[0026] The multi-channel wireless measuring system of the present invention measures structures such as bridges, large facilities and underground pipelines to realize safety assessment and maintenance of structures. The multi-channel wireless measurement system includes various sensors 100 such as strain gage sensors, displacement sensors, load cells, acceleration sensors, speed sensors, noise sensors, and vibration sensors, which are installed in structures such as bridges, large facilities, and underground pipelines to assess and measure the state of the structure. The sensor interface module 200 has a circuit for driving the sensor 100 because the physical quantity of the sensor interface module 200 is different from that of the sensor 100 . The sensor interface module 200 converts the physical quantity of the se...

Abstract

The invention provides a multi-channel wireless measuring system with a separate sensor interface module. A sensor interface module connected to a sensor is detachably coupled to a wireless data logger. The sensor interface module can be used in a multi-channel fashion by constructing a circuit corresponding to each sensor and the sensor interface module can be additionally coupled to the wireless data logger when measuring a structure using a plurality of sensors. The plurality of sensors is connected to one data logger to variously measure the structure.

Description

technical field [0001] The present invention relates to a wireless measurement system that wirelessly receives measured signals from sensors installed in structures such as bridges, large facilities, underground pipelines, etc., and evaluates and measures the structures. More specifically, the present invention relates to a multi-channel wireless measurement system with a separate sensor interface module that can be configured by incorporating sensors (e.g., strain gauge sensors, displacement sensors, load cells, acceleration sensors) , speed sensor, noise sensor and vibration sensor), the sensor interface module of the circuit is separated from the wireless data logger, and the sensor interface module is detachably connected to the signal conditioner of the wireless data logger to measure the structure in a multi-channel manner , and then diagnose and measure the state of the structure. Background technique [0002] Along with construction of new towns, development of indu...
