Wireless inclinometer monitoring system based on FLEX bending sensing and 3D printing technologies

Abstract

The invention discloses a wireless inclinometer monitoring system based on FLEX bending sensing and 3D printing technologies. The monitoring system comprises package housings for manufacturing a wireless inclination monitoring instrument by a 3D printing technique, rotary link hinges arranged between the package housings, hinging bolts connecting the two adjacent package housings, sensor sliding wheels, sensors, an inclinometer tube, a wireless transmitter and a data acquisition and analysis terminal of the sensor. On the basis of a linear relationship between an indication number and a bending angle of a bending sensor, bending angles of all points inside a monitoring slope are overlapped; and the bluetooth wireless transmitter transmit data in real time to realize real-time monitoring of horizontal displacement of all monitoring points. On the basis of combination of the 3D printing technique, the FLEX bending sensor, and the bluetooth wireless transmission technique, the tedious operation process of the device is simplified; and assembling is carried out simply by 3F printing one-time moulding. Besides, with the FLEX bending sensor, great convenience is provided for wireless real-time monitoring of the slope.

Description

Technical field [0001] The present invention relates to a wireless inclinometer monitoring system based on FLEX bending sensing and 3D printing technology. The monitoring system is mainly used for wireless real-time measurement of slope deformation of soils at different depths in geotechnical engineering, belonging to bending Application of sensing technology, 3D printing technology, and wireless transmission technology in the field of intelligent geotechnical monitoring. Background technique [0002] At this stage, our country's slope engineering mainly guarantees the safety and stability of the slope through reliable design, while foreign countries have achieved real-time monitoring of dangerous slopes. As rock and soil mechanics is still in the developing stage, many theories are not perfect, and still need practice and time to test. Only through design to solve, there is a certain degree of uncertainty. Moreover, slope damage has great destructive power. Once it occurs, it w...

Problems solved by technology

Since rock and soil mechanics is still in the development stage, many theories are not yet perfect, and it still needs practice and time to test. Only through design to solve, there is a certain degree of uncertainty

Moreover, the slope damage has great destructive power. Once it occurs, it will cause huge loss of life and property, and greatly threaten the normal life of the people near the slope.

[0003] At present, the existing inclinometers in slope monitoring all have some points to be improved: such as the inclinometer provided by the patent No. CN201903347U connected with the cable and the inclinometer probe, the optical fiber inclinometer provided by the patent No. CN204902782U, etc. The instrument has the problems of complicated installation and use, and is easy to be broken and damaged after long-term use; another example is the slope GPS measuring point monitor provided by the patent number CN205138480U, which is expensive and difficult to popularize, and the slope displacement response is slow, and it will displace in the deep, accurate There is also a total station monitoring, which requires manual monitoring and has certain requirements for weather conditions, so it is difficult to implement long-term real-time monitoring
