Railway grouting remote monitoring device based on Internet of Things technology

Abstract

The invention discloses a railway grouting remote monitoring device based on the Internet of Things technology. The railway grouting remote monitoring device comprises a box body, a detection circuitarranged in the box body and a plurality of interfaces which are arranged on the box body, used for being externally connected with a pressure sensor, a flow sensor, a density sensor, a lifting sensorand a camera and connected with the detection circuit; and the detection circuit comprises a central controller U14, an ADC converter U11, a first differential four-channel digital control analog switch U9, a second differential four-channel digital control analog switch U10, a first signal acquisition circuit, a second signal acquisition circuit, a third signal acquisition circuit, a fourth signal acquisition circuit, a fifth signal acquisition circuit, a sixth signal acquisition circuit, a seventh signal acquisition circuit, an eighth signal acquisition circuit, a video interface chip U13,a communication chip U16 and a power supply circuit. According to the scheme, and the device has the advantages of simple structure, complete acquired signals and the like.

Description

technical field [0001] The invention relates to the technical field of railway grouting detection, in particular to a remote monitoring device for railway grouting based on Internet of Things technology. Background technique [0002] Cement grouting is one of the main methods of railway subgrade karst treatment. Cement slurry is injected into rock mass, soil or structural buildings to cement it into a relatively solid, relatively dense and less permeable whole. Cement grouting can improve the ground conditions of the foundation and treat the foundation of the building to meet the requirements of anti-seepage and reinforcement. But grouting is a concealed project, and its construction quality and effect cannot be evaluated intuitively. It can only be analyzed and evaluated with the help of inspection hole data and grouting construction process record data. In the prior art, the measurement and recording of these data are all done manually, the accuracy of the data will be af...
