Description

Technical Field

[0001] This invention relates to the technical field of ozone generators, specifically to a method for calculating the power of an ozone generator to determine the ozone concentration required by a user under the current ambient temperature. Background Technology

[0002] Ozone generation methods include ultraviolet irradiation, electrolysis, radiochemistry, and dielectric barrier discharge. Dielectric barrier discharge involves filling the space between two discharge electrodes with oxygen and covering one or both electrodes with an insulating dielectric. When a sufficiently high alternating voltage is applied between the electrodes, the gas between them breaks down, and the oxygen is converted into ozone during this breakdown process. These discharge electrodes and insulating dielectrics can be planar or coaxial cylindrical.

[0003] Ozone generators are used to produce high-precision, adjustable-concentration oxygen-ozone mixtures. Research indicates that ozone concentration is related to ambient temperature and high-voltage discharge gap; however, existing commercially available products and academic papers lack algorithms that correlate temperature and discharge gap. Current technologies exhibit significant ozone concentration errors at different temperatures. Existing technologies use piecewise functions, simply mapping concentration to power in segments.

[0004] P={(C2-C) / (C2-C1)*P1+(C-C1) / (C2-C1)*P2}

[0005] P: Current power

[0006] C: Current ozone concentration

[0007] C1: Pre-controlled ozone concentration 1

[0008] C2: Pre-controlled ozone concentration 2

[0009] P1: Power corresponding to pre-set ozone concentration 1

[0010] P2: Power corresponding to pre-set ozone concentration 2

[0011] Using piecewise functions results in larger errors.

[0012] Furthermore, existing technologies do not consider the impact of temperature changes; experimental results show that the temperature affects concentration by an error of up to ±10%. This technology incorporates the influence of temperature into the algorithm, ensuring that ozone concentration remains stable under different temperatures. Summary of the Invention

[0013] The purpose of this invention is to provide a method for calculating the ozone generator power required by the user at the current ambient temperature in order to solve the above-mentioned problems. This method fully considers the influence of temperature on the concentration, incorporates the influence of temperature into the algorithm, and can ensure that the ozone concentration remains stable at different temperatures. The quadratic function calculation is closer to the actual situation and has smaller errors.

[0015] An ozone generator is placed in a first preset temperature environment, and the ozone concentration data emitted by it at different power levels are measured. Based on the ozone concentration data at different power levels, the functional relationship between power and ozone concentration at the first temperature is obtained through a least squares iterative algorithm.

[0021] Calculate the preset temperature power weighting value of the two closest preset temperatures selected;

[0022] Based on the power weighted value of the two closest preset temperatures and the corresponding calculated power, the power concentration required by the user at the current ambient temperature is calculated.

[0023] Furthermore, the weighted values ​​of the two closest preset temperatures relative to the current ambient temperature specifically include:

[0024] n1 = (T2 - T) / (T2 - T1)

[0025] n2 = (T - T1) / (T2 - T1)

[0026] Where: n1 is the power weighting value of preset temperature 1, n2 is the power weighting value of preset temperature 2, T1 is the selected preset temperature 1, T2 is the selected preset temperature 2, and T is the current ambient temperature.

[0027] Furthermore, the step of calculating the power concentration required by the user at the current ambient temperature based on the weighted values ​​of the two closest preset temperatures relative to the current ambient temperature and the calculated corresponding power specifically includes:

[0028] P = n1 * P1 + n2 * P2

[0029] Where: P is the power at the current ambient temperature, P1 is the power at the selected preset temperature 1, P2 is the power at the selected preset temperature 2, n1 is the weighted value of the power at preset temperature 1, and n2 is the weighted value of the power at preset temperature 2.

[0030] Furthermore, after calculating the power concentration required by the user at the current ambient temperature based on the preset temperature power weighted value of the two closest preset temperatures and the calculated corresponding power, the method further includes:

[0031] The calculated power required by the user at the current ambient temperature is transmitted to the ozone generator.

[0032] The ozone generator operates based on the power required by the user at the calculated ambient temperature, outputting high-precision ozone.

[0033] The beneficial effects of the present invention are as follows: The method for calculating the ozone generator power required by the user at the current ambient temperature provides an method that uses ambient temperature weighting to correct the relationship between ozone concentration and power, and uses a quadratic function to calculate the relationship between ozone concentration and power.

This method fully considers the influence of temperature on concentration, incorporates the influence of temperature into the algorithm, and ensures that the ozone concentration remains stable at different temperatures. The quadratic function calculation is closer to the actual situation and has smaller errors.

[0053] Specifically, the weighted values ​​of the two closest preset temperatures relative to the current ambient temperature, as calculated, include:

[0054] n1 = (T2 - T) / (T2 - T1)

[0055] n2 = (T - T1) / (T2 - T1)

[0056] Where: n1 is the power weighting value of preset temperature 1, n2 is the power weighting value of preset temperature 2, T1 is the selected preset temperature 1, T2 is the selected preset temperature 2, and T is the current ambient temperature.

[0057] Specifically, the step of calculating the power concentration required by the user at the current ambient temperature based on the weighted values ​​of the two closest preset temperatures relative to the current ambient temperature and the calculated corresponding power includes:

[0058] P = nl*Pl + n2*P2

[0059] Where: P is the power at the current ambient temperature, P1 is the power at the selected preset temperature 1, P2 is the power at the selected preset temperature 2, n1 is the weighted value of the power at preset temperature 1, and n2 is the weighted value of the power at preset temperature 2.

[0060] In one embodiment of the present invention, after step S7, which calculates the power concentration required by the user at the current ambient temperature based on the power weighted value of the two closest preset temperatures and the calculated corresponding power, the method further includes:

[0061] S9. The calculated power required by the user at the current ambient temperature is transmitted to the ozone generator;

[0062] S10: The ozone generator operates based on the power required by the user at the calculated concentration under the current ambient temperature, outputting high-precision ozone.

[0063] Specifically, refer to Figure 2 As shown, this application uses a first preset temperature of 10°C, a second preset temperature of 21°C, and a third preset temperature of 35°C as examples for illustration. Since the power and ozone concentration are quadratic at the same temperature.

[0064] P = a1C 2 +a2C+a3

[0065] P: Output power, i.e., duty cycle during operation.

[0066] C: Ozone concentration

[0067] a1: Quadratic proportionality coefficient

[0068] a2: One-time issuance ratio coefficient

[0069] a3: Constant term of the quadratic function

[0070] By obtaining the values ​​of a1, a2, and a3 at a specific temperature, the functional relationship between power and concentration at the current temperature can be determined.

[0071] An ozone generator was placed at 10°C, and ozone concentration data were measured at different power levels (duty cycles of 5%, 15%, 25%, 35%, 45%, 55%, and 63%). The least squares iterative algorithm was used to calculate a1, a2, and a3.

[0072] An ozone generator was placed at 21°C, and ozone concentration data were measured at different power levels (duty cycles of 5%, 15%, 25%, 35%, 45%, 55%, and 63%). The least squares iterative algorithm was used to calculate a1, a2, and a3.

[0073] An ozone generator was placed at 35°C, and ozone concentration data were measured at different power levels (duty cycles of 5%, 15%, 25%, 35%, 45%, 55%, and 63%). The least squares iterative algorithm was used to calculate a1, a2, and a3.

[0074] Record a1, a2, and a3 at temperatures of 10℃, 21℃, and 35℃.

[0075] Place the ozone generator in a normal environment, and the user inputs the desired ozone concentration.

[0076] Ambient temperature is collected using a temperature sensor. The ambient temperature is compared with preset temperatures (10℃, 21℃, 35℃). The two preset temperatures closest to the ambient temperature are selected, and the formula P = a1C is applied to the preset temperatures. 2 The function +a2C+a3 is used to calculate the corresponding power P1 and P2.

[0077] The power corresponding to the current temperature is calculated using the following formula:

[0078] P = n1 * P1 + n2 * P2

[0079] P: Power at the current temperature

[0080] P1: Preset temperature and power

[0081] P2: Preset temperature, power

[0082] n1: Preset temperature and power weighting value

[0083] n2: Preset temperature + power weighting value

[0084] The formula for calculating the weighted value is as follows:

[0085] n1 = (T2 - T) / (T2 - T1)

[0086] n2 = (T - T1) / (T2 - T1)

[0087] T1: Preset temperature 1

[0088] T2: Preset temperature 2

[0089] T: Current temperature

[0090] The system calculates a weighted average of the ambient temperature and the preset temperature. Using the weighted average and the corresponding power, it calculates the power required by the user at the current ambient temperature and outputs the power to the ozone generator. The ozone generator then outputs high-precision ozone.
