Foundation ditch on-line monitoring system comprehensive data storage transmission device

Abstract

The invention relates to a foundation ditch on-line monitoring system comprehensive data storage transmission device. The foundation ditch on-line monitoring system comprehensive data storage transmission device comprises a core processor U1, a serial port interface U7, a USB interface U6, a CAN bus communication module U8, a CAN bus interface U9, a bluetooth data communication module U4, a 4G data communication module U3, and a 433MHZ data communication module U2. The foundation ditch on-line monitoring system comprehensive data storage transmission device is capable of integrating all the existing foundation ditch monitoring instrument data transmission modes, one-site data format parsing is avoided, all the files are stored in a register directly, so that on-site data reading process issimplified. After test, data is sent to a on-site data terminal for sending to a cloud platform through the 433MHZ data communication module in the foundation ditch on-line monitoring system comprehensive data storage transmission device, or is directly sent to the cloud platform for processing through the 4G module of the foundation ditch on-line monitoring system comprehensive data storage transmission device. The foundation ditch on-line monitoring system comprehensive data storage transmission device is capable of increasing on-site data storage and sending convenience and universality effectively, and increasing on-site working efficiency.

Description

technical field

[0001] The invention relates to the field of foundation pit, slope, bridge and tunnel monitoring, and relates to a comprehensive data storage and transmission device for an online foundation pit monitoring system. Background technique

[0002] At present, the foundation pit monitoring content includes: displacement of the top of the enclosure pile and the top of the slope soil (using instruments include: theodolite, total station, GPS); deep displacement of piles, walls and soil (using instruments including: inclinometer) ; internal force of pile wall (use instruments include: steel stress sensor, frequency meter); water and soil pressure of pile wall (use instruments include: pressure box, pore water pressure probe, frequency meter); vertical displacement of ground surface, surrounding buildings, underground pipelines, etc. (Instruments used include: level gauge); supporting axial force (instruments used include: steel bar stress sensor, displacement meter, ...
