An embodiment of the moisture content detection method of the present invention:
wall mold refers to a fungus colony which is parasitic on the surface of a wall body in a flora manner and proliferates in a large quantity by utilizing available carbon sources and nitrogen sources in a wall skin layer (generally referred to as a putty layer and a finish paint layer) under proper temperature and humidity. In humid areas, wall mold is particularly prone to growth due to the high humidity in the air.
The growth of mold on the wall can nourish the monitoring of residents, and the service life of the wall can be shortened. However, at present, only when the wall is bred with mould, the mould can be found and then treated. The breeding of the wall mould cannot be effectively prevented. The most important condition for the breeding of the mildew on the wall body is that the humidity of the wall body meets the breeding condition of the mildew. However, currently, the humidity of the wall body can be judged only by means of visual observation. Therefore, the defects that the judgment result is inaccurate and the humidity of the wall body cannot be described quantitatively exist.
In order to solve the above-mentioned drawbacks, the present embodiment proposes a moisture content detection method applied to a moisture content detection apparatus. Referring to fig. 3, the moisture content sensing apparatus may comprise a control assembly 10, a first electrode 41 and a second electrode 42. The first electrode 41 and the second electrode 42 are embedded in the object to be measured at intervals. The object to be measured may be a ceiling 21, a wall 22 and/or a floor 23 of a building. So that the object to be measured is filled between the first electrode 41 and the second electrode 42. The first electrode 41 and the second electrode 42 thus form a capacitor with a medium filled in between the objects to be measured. In addition, the first electrode 41 and the second electrode 42 are connected to the control assembly 10, so that the control assembly 10 and the first electrode 41 and the second electrode 42 can form a capacitance circuit.
Optionally, a detection unit 30 may be disposed between the first electrode 41 and the second electrode 42 and the control assembly 10. Wherein the detection unit 30 is arranged to detect the capacitance of the capacitance formed by the first electrode 41 and the second electrode 42.
Referring to fig. 2, in an embodiment of the moisture content testing method of the present invention, the moisture content testing method comprises the steps of:
step S10, acquiring a preset detection voltage, and controlling the detection current of the first electrode and the second electrode to be electrified based on the preset detection voltage;
step S20 of detecting a capacitance between the first electrode and the second electrode;
and step S30, determining the current moisture content of the target to be measured according to the capacitance.
In this embodiment, the preset detection voltage may be obtained first. Wherein, the preset detection voltage refers to a voltage amplitude value pre-stored in the storage medium. And after the preset detection voltage is acquired, the preset detection voltage is used as the input voltage of the capacitor formed by the first electrode and the second electrode. To charge the capacitance formed by the first electrode, the object to be measured and the second electrode.
Then, a charging period of the capacitor may be acquired, and a capacitance of the capacitor formed by the first electrode, the object to be measured, and the second electrode may be detected based on the charging period. I.e. the capacitance between the first electrode and the second electrode is detected.
When the capacitance is acquired, the current moisture content of the target to be measured can be determined based on the capacitance.
Specifically, after the above capacitance is acquired, a direct mapping relationship between the prestored capacitance and the moisture content may be acquired. The mapping relationship may be stored in the storage medium in the form of a graph, or may also be stored in the storage medium in the form of a two-dimensional table. Alternatively, the capacitance as a function of moisture content may be fitted. And then the functional relationship is used as the mapping relationship. The current moisture content may then be determined based on the mapping and the capacitance.
The relative dielectric constant of water at room temperature is much higher than that of other materials, the higher the relative dielectric constant is, the more 80. Therefore, the dielectric constant of the insulator increases sharply as the moisture content of the insulator increases. The moisture content of the target to be detected can be detected by utilizing the characteristic. That is, when the moisture content of the target is detected, the target is located between the capacitors formed by the first electrode and the second electrode, and then the moisture content of the target located between the first electrode and the second electrode can be determined according to the capacitance of the capacitors.
Alternatively, in the present embodiment, the steps S10 to S30 may be performed when a preset condition is satisfied.
Specifically, the preset condition includes that the air humidity in the space where the target to be detected is located is greater than a preset humidity; receiving a moisture content detection control instruction; and/or the current time point is a preset moisture content detection time point.
Example 1, the moisture content detecting apparatus is further provided with a humidity detecting sensor so that the ambient humidity in the space where it is located, that is, the air relative humidity can be detected by the humidity detecting sensor. When the air humidity is larger than the preset value, the situation that the humidity of the environment is larger at the current moment is shown, and the phenomenon that the moisture regains when waiting for the measured object such as a wall body and a bottom plate is easily caused. Thus, steps S10-S30 may be performed at this point to determine the moisture content of the wall and/or floor for the user to determine if there is a risk of wall mold growth.
Example 2, the moisture content testing apparatus is further provided with a user interface through which a user may interact with the moisture content testing apparatus. Wherein the user interface detects a function activation button. And when the detection function starting button is triggered, judging that a moisture content detection control instruction is received. Thus, steps S10-S30 are performed to determine the moisture content of the wall and/or the ground.
It should be noted that the moisture content detection control instruction may also be sent to the moisture content detection device by other means, for example, by using a mobile control terminal connected to the moisture content detection device, sending the moisture content detection control instruction to the moisture content detection device, and so on. This allows the moisture content to be detected remotely when the user is not resident in the building for a long period of time.
Example 3, the moisture content may be set to be detected at a timing. Wherein the timing interval can be customized by a user. Alternatively, the moisture content detection may be scheduled, for example, setting a detection time point or the like. So that when the current time point is the preset moisture content detection time point, the steps S10-S30 are performed to determine the moisture content of the wall and/or the ground.
Optionally, after determining the current moisture content of the target to be measured according to the capacitance, the current moisture content may be output. Wherein the step of outputting the current moisture content comprises at least one of:
firstly, displaying the current moisture content in a display device;
specifically, the moisture content detection device is provided with a user interface, and the user interface comprises a display screen. After determining the current moisture content, the current moisture content may be displayed in a display screen in the form of a numerical value or a graph.
Secondly, the current moisture content is sent to a target terminal, so that the current moisture content is displayed through the target terminal;
specifically, the current moisture content may be sent to a target terminal, where the target terminal may be a terminal connected to the moisture content detection device through a local area network or the internet. For example, the mobile terminal may be a mobile terminal such as a mobile phone, a tablet computer, and a notebook computer, or may be a network terminal such as a PC and a server.
And thirdly, when the current moisture content is larger than the preset moisture content, outputting alarm information of overlarge moisture content.
Specifically, the preset moisture content may be set by a user, or the minimum moisture content prone to mildew may be set as the preset moisture content by a producer based on empirical data. And judging the size relation between the current moisture content and the preset moisture content after the current moisture content is obtained. And when the current moisture content is larger than the preset moisture content, judging that the current target to be detected is easy to breed the wall body mould, and outputting alarm information with overlarge moisture content. The outputting of the warning information with excessive moisture content may include displaying a prompt text and/or a pattern, controlling a preset indicator light, and turning on or off the preset warning mode. Or output an alarm prompt voice.
Alternatively, in an application scenario, since in current buildings, water pipes are typically buried in walls. When the water pipe is broken due to aging or other factors. Water leakage can result. Thus, the moisture content of the wall or the ground around the water pipe can also be detected. And the moisture content of the wall or ground surrounding the non-water pipe. And judging that the water pipe leaks water when the difference between the moisture content of the wall body around the water pipe or the ground and the moisture content of the wall body around the non-water pipe or the ground is larger than a preset difference water. Or when the moisture content of the wall body around the water pipe or the ground is larger than a preset threshold value, judging that the water pipe leaks water. The specific values of the preset difference and the preset threshold are not specifically limited in this embodiment, and may be set by user according to an empirical value.
It should be noted that, in some application scenarios, the factors that cause the water content of the wall and/or the ground to increase further include untimely drainage of the drainage pipe, leakage of the water pipe, and/or seeping of water into the wall when water is used. And the increase speed and the increase amount that wall body and/or ground water content that different factors lead to increase are different, consequently, can be according to empirical data, set up the drain pipe drainage untimely, water pipe breakage leak and/or when using water ponding infiltration wall body corresponding water content increase speed threshold value and water content threshold value to according to the contrast result between the water content increase speed that detects in time and the water content increase speed threshold value, and/or the contrast result between water content threshold value and the current water content that detects, confirm to lead to the great factor of wall body and/or ground water content.
Optionally, referring to fig. 4, in an embodiment, after the step S30, the method further includes:
and step S40, when the current moisture content is larger than the preset moisture content, sending a starting instruction to the wall body and/or floor drying device to control the wall body and/or floor drying device to start.
Specifically, the target to be detected is a wall body and/or a ground, the moisture content detection device is in communication connection with a wall body and/or a ground drying device, and after the step of determining the current moisture content of the target to be detected according to the capacitance, when the current moisture content is larger than a preset moisture content, a starting instruction is sent to the wall body and/or the ground drying device to control the wall body and/or the ground drying device to start. The wall body and/or floor drying device can be closed after running for a preset time, or can be closed when the current moisture content is smaller than the preset moisture content, or can be manually closed by a user.
In the technical scheme disclosed in this embodiment, a preset detection voltage is obtained, the detection current where the first electrode and the second electrode are located is controlled to be electrified based on the preset detection voltage, the capacitance between the first electrode and the second electrode is detected, and the current moisture content of the target to be detected is determined according to the capacitance. Because the moisture content of the target to be measured can be accurately determined, the accuracy of the moisture content judgment result is improved, and the effect of quantitatively describing the wall humidity is realized.
Furthermore, an embodiment of the present invention also provides a moisture content detecting apparatus, where the moisture content detecting apparatus includes a memory, a processor, and a moisture content detecting program stored on the memory and executable on the processor, and the moisture content detecting program, when executed by the processor, implements the steps of the moisture content detecting method according to each of the above embodiments.
