Description

Apparatus and Method for measuring Moisture Vaporization Amount of Road}

The present invention relates to a road moisture evaporation measurer and measurement method, and more particularly, to a road moisture evaporation measurer and measurement method for effectively measuring the moisture evaporation of a concrete surface during road pavement construction.

Since concrete used in road pavement construction may crack under the influence of temperature and humidity during construction work, it is necessary to manage and inspect to increase strength by maintaining a uniform drying speed.

In the existing road pavement work, inspection of the concrete surface was usually performed through visual observation. However, in the case of visual observation, there is a disadvantage in that the measured value is different according to the individual difference of the measurer, and effective moisture management is not achieved due to the subjectivity of the measurer.

In addition, the method of checking by observing with the naked eye is not only less efficient, but also requires a measurer to visit the site from time to time, and it is difficult to quickly take action to prevent moisture on the concrete surface from evaporating according to the site situation in real time.

Here, the housing 100 may be formed of a tubular member extending in a longitudinal direction of one axis and having a cross section in a width direction of any one of a circular shape, an elliptical shape, and a polygonal shape.

It may include a second temperature and humidity sensor 220 disposed apart from each other by a set distance to detect temperature and humidity and a gas sensor 230 disposed at the inlet 110 of the housing 100 to detect gas.

In addition, the second temperature and humidity sensors 220 are configured as a pair and may be disposed facing each other on the opposite side (inside the inside) of the inlet 110 of the housing 100 . For example, the second temperature and humidity sensor 220 includes a first inner sensor 221 and a second inner sensor disposed facing each other in a middle portion of the housing 100 based on a cross section of the housing 100 in the width direction. (222).

Here, the magnetic body 310 may include at least one of a permanent magnet and an electromagnet. The blowing unit 300 may include a fan capable of blowing air in both directions in a forward direction (a direction drawn into the housing) and a reverse direction (a direction drawn out of the housing).

For example, the communication unit 430 may transmit the moisture evaporation amount to the user's portable terminal and provide it to the user, or may receive the user's set input value and transmit it to the central processing unit 410 .

The infrared temperature measuring unit 500 may measure the temperature by radiating infrared rays to the surface 30 of the target object 20 .

At this time, the infrared emissivity may vary depending on what material is present on the surface 30 of the target object 20 . Here, since the emissivity of infrared rays varies on the surface 30 depending on the target object 20, the emissivity may be set by reflecting the correction coefficient in order to compensate for the emissivity that varies.

For example, when there is water on the surface 30 of the target object 20, before measuring the amount of water evaporation, the central processing unit 410 determines the infrared emissivity using an infrared sensor, and The amount of water evaporation can be measured by reflecting the presence of water. Alternatively, in the case where only concrete is present on the surface 30 of the object 20, the central processing unit 410 determines the infrared emissivity using an infrared sensor before measuring the amount of moisture evaporation, and only concrete is present on the surface 30. It is possible to measure the amount of moisture evaporation by reflecting the present state. Alternatively, when there is a film curing agent on the surface 30 of the object 20, the central processing unit 410 determines the infrared emissivity using an infrared sensor before measuring the amount of moisture evaporation, and the concrete is applied to the surface 30.
