Device for wirelessly measuring whole-age humidity of concrete panel and using method

Abstract

The invention provides a device for wirelessly measuring the whole-age humidity of a concrete panel and a use method. The device is characterized in that the device comprises an acquisition device, arelay routing device, and a receiving terminal device, wherein the acquisition device comprises a waterproof shell, and an acquisition circuit board and a battery which are arranged in the waterproofshell; a humidity sensor, an acquisition circuit, a wireless module and a power supply module which are connected in sequence are integrated on the acquisition circuit board; the power supply module is connected with the battery; a probe of the humidity sensor extends out of the waterproof shell, and the extending part of the probe is covered with an e-PTFE film and is in water-tight connection with the waterproof shell through an organic silicon sealant; the relay routing device comprises a wireless gain module and a routing module; and the receiving terminal device comprises a wireless receiving module. The device is ingenious in design, high in precision and good in stability, can monitor the internal humidity of the concrete panel for a long time in a high-humidity environment, and isnot easily disturbed by external conditions.

Description

technical field [0001] The invention belongs to the technical field of concrete monitoring, sensing and control, and in particular relates to a wireless monitoring device with a waterproof function for the humidity of concrete panels in all ages and a use method thereof. Background technique [0002] Humidity shrinkage causes early cracking of cement concrete pavement, and humidity warping is an important part of cement concrete pavement warping, which affects the support state of pavement and the performance of service period under vehicle load. The whole-age humidity monitoring of concrete pavement has been paid more and more attention. Traditional humidity monitoring systems are mostly used in factories, workshops, environmental fields, etc. For the high-humidity environment (95%~100%) inside the cement concrete pavement early stage, it is easy to cause short-circuit failure of the humidity sensor. However, for high-precision monitoring Humidity again cannot completely s...

AI Technical Summary

Problems solved by technology

Traditional humidity monitoring systems are mostly used in factories, workshops, environmental fields, etc. For the high-humidity environment (95%~100%) inside the cement concrete pavement early stage, it is easy to cause short-circuit failure of the humidity sensor. However, for high-precision monitoring Humidity does not completely seal the sensor

Several experimental studies have shown that conventional humidity sensors have a low survival rate when monitoring the humidity inside concrete

[0003] In addition, during the construction of cement concrete pavement, the traditional wired transmission equipment reduces the flexibility of the monitoring system and the convenience of construction due to the laying of a large number of cables. Mutual interference occurs, especially when there are many measuring points, the wiring will be more complicated and the cost will be higher
