Calculating the service time of the magnesium rod 200 according to the ion concentration information;
acquiring the consumed time of the magnesium rod 200;
If the consumed time is longer than the using time, a display instruction is sent to the display panel to control the display panel to display the information of replacing the magnesium rod 200.
The substances in water which are most prone to form scale are calcium and magnesium ions. The calcium and magnesium ions combine with carbonate ions and sulfate ions in water during heating to form a precipitate which is difficult to dissolve in water and adheres to the outer wall of the magnesium rod 200 to form scale.
The calcium and magnesium ion detection electrode is an electrochemical sensor for detecting the concentration of calcium ions and magnesium ions in a water sample, and consists of a sensitive film and a pair of conductive electrodes, and can measure the potential or current in the water sample and calculate the concentration of the calcium ions and the magnesium ions in the water sample according to the measurement result. The sensitive membrane of the calcium-magnesium ion detection electrode is usually composed of a selective membrane capable of selectively recognizing calcium ions and magnesium ions, and can distinguish the calcium ions and the magnesium ions from other ions in the water sample. The conductive electrode of the electrode is used for measuring the potential or current on the sensitive film and transmitting the measurement result to the controller.
By way of example, the calcium and magnesium ion detection electrode calculates the formation time of scale possibly attached to the magnesium rod 200 by detecting the concentration of calcium and magnesium ions in water in the liner 100 and by calculating the size of the concentration of ions, thereby determining the service time of the magnesium rod 200, and if the elapsed time of the magnesium rod 200 is greater than the service time, the controller counts up three times, in this embodiment, when the counted up number is greater than or equal to three, that is, the preset count threshold is three times, the user is prompted to replace the magnesium rod 200, wherein the information that needs to be replaced can be displayed through the display panel.
Because the display area of the display screen arranged on the electric water heater is limited, the magnesium rod can be displayed to be replaced; the APP of the terminal may also display information of detecting the magnesium rod 200 each time, and accumulating the counted time and information, so as to be more convenient for the user to understand the status of the magnesium rod 200, in some embodiments, the electric water heater further includes a profile measuring ring 510 and a stretching assembly 520, see fig. 2, the stretching assembly 520 is connected with the profile measuring ring 510, the profile measuring ring 510 is sleeved on the magnesium rod 200, the profile measuring ring 510 includes a sensor assembly, the sensor assembly is one or more of a capacitive sensor, a resistive sensor, and an optical sensor, and the profile measuring assembly and the stretching assembly 520 are in communication connection with the controller.
The radius of the profile measuring ring 510 is larger than that of the magnesium rod 200, and the thickness of the scale on the magnesium rod 200, which needs to be replaced, can be detected to set the radius of the profile measuring ring 510, so that the profile measuring ring 510 can sense the distribution of the scale. It should be noted that to detect the scale distribution of the magnesium rod 200, the radius of the profile measuring ring 510 is smaller than the minor diameter of the heater 400 and larger than the radius of the magnesium rod 200. That is, the heater 400 is also sleeved outside the profile measuring ring 510.
In some embodiments, the stretching assembly 520 includes a fixing base and a stretching rod, the fixing base is connected with the stretching rod, the fixing base provides stretching support for the stretching rod, and the stretching rod can drive the profile measuring ring 510 to detect the distribution and thickness of the scale according to the instruction of the controller. In order to make the detection of the profile measuring ring 510 more accurate, the radius of the magnesium rod 200 may be measured in advance, so that more accurate thickness information may be obtained.
The capacitance sensor is used for detecting non-electric quantity, such as displacement, pressure, liquid level and the like, has the characteristics of high sensitivity, strong controllability, high precision and the like, and detects the change of an object to be detected by utilizing the change of capacitance.
The resistance sensor is used to convert the change in resistance value into an electrical signal, in which embodiment the resistance sensor can infer its thickness and distribution by measuring the change in resistance value of the scale.
In this embodiment, the optical sensor can infer information such as the shape and thickness of the scale by detecting characteristics such as reflection and absorption of light by the scale.
The controller is configured to:
If the accumulated count is greater than or equal to one time, a start instruction is sent to the stretching assembly 520 to control the stretching assembly 520 to drive the profile measuring ring 510 to move along the magnesium rod 200, and a detection instruction is sent to the sensor assembly to control the sensor assembly to detect thickness information and distribution information of scale on the magnesium rod 200.
Generating a magnesium rod 200 model according to the thickness information and the distribution information;
the magnesium stick 200 model information is transmitted to the display panel to cause the display panel to display the magnesium stick 200 model.
Illustratively, when the accumulated times are more than or equal to 1 time, the stretching rod drives the contour measuring ring 510, and the capacitance sensor, the resistance sensor and the optical sensor on the contour measuring ring 510 detect the distribution and thickness information of the scale on the magnesium rod 200, so as to establish a mathematical model describing the shape and structure of the magnesium rod 200. For example, a cylindrical model may be used to describe the overall shape of the magnesium rod 200 and discrete points may be used to represent the distribution information. Parameters in the mathematical model are correlated to thickness and distribution information measured by the contour measurement ring 510.
The model may also be trained using a large number of samples in advance, and it may be checked whether the model can accurately describe the shape and distribution of the magnesium rod 200 by comparing the model prediction result with the large number of sample data. If errors exist, the mathematical model can be adjusted and optimized to achieve a more accurate description.
After the detection is completed, the magnesium rod 200 model with the scale is displayed on the APP of the user terminal, so that the user can visually check the scale distribution on the magnesium rod 200.
The controller is used for receiving the data of the sensor assembly and continuously controlling the movement of the telescopic assembly according to the data. The controller may employ an automated control system, analyze the sensor data through an algorithm, determine the scale distribution and protrusion, and control the stretching assembly 520 to move up and down to achieve comprehensive detection and measurement of the scale around the magnesium rod 200.
