Bridge construction monitoring system based on Internet of Things

Abstract

The invention discloses a bridge construction monitoring system based on the Internet of Things. The system comprises a signal sampling module and a phase-shifting comparison module, the signal sampling module samples node signals in a bridge construction monitoring system by using a signal sampler J1 of which the model is DAM-3056AH; the phase-shifting comparison module receives signals output bythe signal sampling module in two paths; an operational amplifier AR2, a diode D4 and a diode D5 are used for forming a peak detection circuit for screening peak signals in one path of signals; a phase shift circuit composed of an operational amplifier AR4, a resistor R4 and a capacitor C3 is used for carrying out phase shift on the two paths of signals to eliminate signal peaks. An operational amplifier AR3 is used for comparing the two paths of signals; and finally, an operational amplifier AR6, a capacitor C1 and a capacitor C2 are used to form a noise reduction circuit to perform noise reduction adjustment on the signal. The output signal of the operational amplifier AR6 is sent to a bridge construction monitoring system terminal through the signal emitter E1, and a node signal in thebridge construction monitoring system can be sampled and adjusted and converted into a correction trigger signal of the bridge construction monitoring system terminal.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a bridge construction 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 "informationization" era. The combination of bridge construction and the Internet of Things has improved the management efficiency of bridge construction status data. At the same time, bridge construction data needs to be real-time based on the construction status. Monitoring to avoid data deviation during bridge construction, but bridge 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. However, bridge construction has For high-frequency equipment, t...
