Building construction information monitoring system based on Internet of Things

Abstract

The invention discloses a building construction information monitoring system based on the Internet of Things. The building construction information monitoring system comprises a signal sampling module and a separation calibration module, the signal sampling module samples output signals of signal acquisition equipment in the building construction information monitoring system by using a signal sampler J1 of which the model is DAM-3056AH; the separation and calibration module receives signals output by the signal sampling module; the separation and calibration module detects abnormal signals by using a triode Q2, a triode Q3 and a capacitor C5; abnormal high-level signals in the signals are detected by using cut-off voltages of the triode Q2 and the triode Q3; a diode D7 is designed in onepath to detect signals; a signal is fed back to the inverting input end of the operational amplifier AR3; and the operational amplifier AR3 adjusts two paths of output signals to the inverting inputend of the operational amplifier AR4 by utilizing feedback signals of the diode D7, so that the signal receiving accuracy of the building construction information monitoring system terminal and the signal receiving of the building construction information monitoring system terminal are ensured, and the response is made in time.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a building construction information monitoring system based on the Internet of Things. Background technique [0002] The Internet of Things is an important part of the new generation of information technology, and it is also an important development stage in the "informatization" era. The combination of building construction and the Internet of Things has improved the management efficiency of building construction status data. At the same time, building construction data needs to be real-time based on the construction status. Monitoring to avoid data deviation during building construction, but building construction monitoring needs to transmit a large amount of data information in real time, and the accuracy of data must be ensured, especially in the middle of construction, data signals need to ensure real-time and accuracy, and ensure data accuracy However, when t...
