[0080] In embodiment 1 step (1), it is determined that the launch point and the collection point of the wall inner surface of the space to be detected are selected as follows:

[0081] (1) In order to ensure the effectiveness and accuracy of the air humidity, wall humidity, and rock-soil humidity in the space to be tested, the layout of the emission points and collection points was optimized by grid. The width of an underground wall is 1000 cm, The height is 400 cm, and the preferred width and height of each area are 100 cm and 100 cm respectively, then each wall surface of the space to be tested is divided into 1000 / 100×400 / 100=40 areas;

[0085] According to the relationship between the electric field intensity and the current density of the steady current field, Ohm's law is satisfied, and its differential form formula is:

[0086] E. i =ρJ i

[0087] E. i is the electric field intensity vector; J i is the current density vector; i=1,2. ρ is the resistivity.

[0088] Extend the formula to a two-component formula:

[0089]

[0090] Further, calculate the current component of the underground wall:

[0091] Let the power supply electrode A i The radius r Ai =(x Ai ,y Ai ), then the current density component formula at any field point M on the full plane (vector radius is r=(x,y)) is:

Abstract

The invention discloses an underground space humidity calculation method and application thereof in an electronic anti-seepage system of the Internet of Things, and belongs to the technical field of dehumidification anti-seepage control. In order to solve the problem that humidity collection of existing equipment is not accurate, anisotropic response characteristics of an underground wall and rock soil are studied, the moisture content and humidity values of the underground wall and the rock soil are calculated through a resistivity method, and therefore comprehensive and accurate spatial distribution of humidity of a rock soil layer and concrete is obtained. A traditional humidity measurement method can only measure the surface humidity of a wall body, but the resistivity of a space body of the wall body and outer rock soil can be measured based on a resistivity method, so that the moisture content and the humidity value are obtained. The method is applied to an electronic anti-seepage system of the internet of things, so that underground walls and rock soil are detected, more accurate moisture content and humidity values are obtained, the voltage value of anti-seepage equipment can be modified in time to dehumidify the walls, and the humidity of the space in a basement is more effectively reduced.

Description

technical field [0001] The invention belongs to the field of moisture-proof and dehumidification of underground buildings, and in particular relates to a method and system for calculating humidity in an underground space based on resistivity. Background technique [0002] Electro-osmosis anti-seepage dehumidification is an anti-seepage dehumidification and anti-mildew technology, which is mainly used in waterproof, anti-seepage, moisture-proof and dehumidification fields in underground projects, tunnels, power stations, reservoir dams, military industries, construction and other projects. This technology breaks the traditional concept of waterproofing, "using water to control water". According to the principle of electroosmosis, it develops a new type of anti-seepage, moisture-proof and mildew-proof technology through a series of low-voltage multi-pulse positive and negative charges. It can completely and permanently solve the structural problems. Leaking damp and mold probl...
