Split-type mini multifunctional concrete temperature intelligent on-line monitoring system

Abstract

The invention discloses a split-type mini multifunctional concrete temperature intelligent on-line monitoring system. An encoder chip (3) comprises an IIC storage chip. The IIC storage chip is used for storing serial number information in one-to-one correspondence to temperature sensors. An acquisition system is connected to the two ends of a temperature acquisition resistor (2) through a temperature line and a GND line; and the acquisition system is connected with the IIC storage chip through an IIC frequency line and an IIC data line. Each measurement interface can be expanded, thereby greatly increasing the number of the sensors; the system supports mix-match measurement of thermistor, platinum resistor and copper resistor sensors; each sensor has unique identification, and sensor can be located conveniently after line breaking, thereby effectively improving sensor survival rate, and ensuring no blind point of temperature monitoring; the system can realizes the following functions through software: carrying out automatic alarming when the system exceeds a safety value, carrying out GPS positioning and theft prevention, and realizing spot measurement, subsection cycle measurement and automatic cycle measurement and the like; and the system has reserved auxiliary function interfaces selectively used as needed for environment condition monitoring and external power source and the like, and the effects of convenient realization and plug and play are achieved.

Description

technical field [0001] The invention relates to a detachable mini multifunctional concrete temperature intelligent on-line monitoring system. Background technique [0002] During the solidification process of concrete, heat of hydration is generated, which increases the temperature of the concrete and causes cracks due to deformation, which brings great hidden dangers to the safety of the dam. At present, the monitoring of concrete temperature mainly adopts manual methods: the monitoring methods of manual on-site reading and indoor collation and analysis of data make the real-time performance of temperature monitoring poor, and there are human errors. It is related to the requirement to deliberately adjust the measured concrete temperature value, and it is affected by factors such as the technical level of the personnel and the habit of measuring readings, which cannot show the real condition of the concrete, which brings hidden dangers to the quality and safety of the dam. ...

AI Technical Summary

Problems solved by technology

If the uncertain factors of the installation point (such as the displacement caused by vibration) are not cleaned up during the on-site installation of the sensor, it will directly affect the accuracy of data reading, analysis and results

The existing temperature sensor buried in the concrete cannot be identified and cannot be replaced after an accidental disconnection, which reduces the survival rate of the temperature sensor and also causes blind spots in the temperature monitoring inside the concrete. security risks

[0005] Furthermore, the temperature sensor of the existing concrete temperature monitoring system is buried in the concrete, and it is easy to overlap with the steel bars in the concrete, causing the performance of the temperature sensor to decline or even lose its function, posing a huge safety hazard
