[0022] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0024] Example 1

[0025] According to an embodiment of the present invention, an embodiment of a method for monitoring electromagnetic leakage is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0026] Figure 1 FIG. 1 is a flow chart of a method for monitoring electromagnetic leakage according to an embodiment of the present invention. Figure 1 As shown, the method includes the following steps:

[0027] Step S102, obtaining a target temperature value set of a target location area of ​​the wireless charging system;

[0028] Step S104, sending the target temperature value set to the cloud platform for processing to obtain a processing result;

[0029] Step S106, receiving the processing result returned by the cloud platform;

[0030] Step S108: determining the electromagnetic leakage status of the wireless charging system based on the above processing result.

[0031] In an embodiment of the present invention, the executor of the electromagnetic leakage monitoring method of the above-mentioned steps S102 to S108 is an electromagnetic leakage monitoring system, which uses the above-mentioned system to obtain a target temperature value set of the target location area of ​​the wireless charging system; sends the above-mentioned target temperature value set to a cloud platform for processing to obtain a processing result; receives the above-mentioned processing result returned by the above-mentioned cloud platform; and determines the electromagnetic leakage situation of the above-mentioned wireless charging system based on the above-mentioned processing result.

[0032] As an optional embodiment, Figure 2The overall structure of the electromagnetic leakage monitoring system shown in the figure mainly includes: temperature probes, a temperature acquisition gateway, and a cloud platform. At locations 1-8 in the figure, a magnetic field meter can be used to measure the temperature at each location, while high-precision non-ferrous temperature sensors can also be used to measure the temperature at each location to establish a relationship between magnetic field leakage and temperature sensing. In actual application scenarios, only iron-cased temperature probes need to be installed at locations 1-8. The iron casing absorbs electromagnetic leakage, causing eddy currents to rise in the temperature probe casing. The built-in temperature sensor senses the temperature, sends it to the temperature acquisition gateway, and transmits it to the cloud platform. The electromagnetic leakage value can be inferred from the temperature measurement and the relationship between magnetic field leakage and temperature sensing.

[0033] In the embodiment of the present invention, the temperature is measured by an iron sensor using the eddy current heating principle, and electromagnetic leakage is calculated conversely. This is an indirect measurement method, that is, the temperature is measured and the electromagnetic leakage is calculated.

[0034] In an optional embodiment, the above-mentioned acquisition of the target temperature value set of the target position area of ​​the wireless charging system includes: setting a plurality of temperature probes in the above-mentioned target position area of ​​the above-mentioned wireless charging system, wherein each of the above-mentioned plurality of temperature probes is separated by a first preset distance; using the above-mentioned plurality of temperature probes to acquire a plurality of initial temperature values, wherein each of the above-mentioned plurality of initial temperature values ​​corresponds to one of the above-mentioned temperature probes; and determining the above-mentioned target temperature value set based on the above-mentioned plurality of initial temperature values.

[0035] As an optional embodiment, Figure 3 The temperature probe installation diagram shown in the figure shows that temperature probes are installed at locations 1, 2, 3, 4, 5, 6, 7, and 8, respectively, rather than electromagnetic testing equipment. This is mainly because electromagnetic testing equipment is expensive and not feasible for large-scale application. The aforementioned temperature probes are used to obtain initial temperature values ​​at multiple locations to construct the target temperature value set.

[0036] In an optional embodiment, before sending the above-mentioned target temperature value set to the cloud platform for processing and obtaining the processing results, the above-mentioned method also includes: setting a plurality of magnetic field meters in the above-mentioned target position area of ​​the above-mentioned wireless charging system, wherein each of the above-mentioned plurality of magnetic field meters is separated by a second preset distance; using the above-mentioned plurality of magnetic field meters to obtain a plurality of initial magnetic field leakage values, wherein each of the above-mentioned plurality of initial magnetic field leakage values ​​corresponds to one of the above-mentioned magnetic field meters; based on the above-mentioned initial magnetic field leakage values, determining a first relationship, wherein the above-mentioned first relationship is used to characterize the relationship between electromagnetic leakage and distance.

[0037] As an optional embodiment, Figure 4The schematic diagram of the magnetic field meter installation position is shown. By setting up multiple magnetic field meters in the target location area in the laboratory and measuring the electromagnetic leakage energy, it can be seen that the closer the distance to the primary coil, the more serious the electromagnetic leakage. The energy corresponding to the electromagnetic leakage can be calculated according to the following formula:

[0038]

[0039] Where σ is the conductivity of the core material (9.93×10 6 Meohm), f is the power frequency 85Khz, d is the thickness of the laminate (2cm), and Bm is the amplitude of the magnetic induction intensity.

[0040] In an optional embodiment, the target temperature value set is sent to a cloud platform for processing to obtain a processing result, including: determining a second relationship based on the first relationship and the target temperature value set, wherein the second relationship is used to characterize the relationship between electromagnetic leakage and temperature; determining a temperature rise value using a third relationship and the second relationship, wherein the third relationship is used to characterize the relationship between the material of the temperature probe and the temperature; and determining whether the temperature rise value is greater than a preset threshold to obtain the processing result.

[0041] As an alternative embodiment, if the primary transformer and secondary transformer are installed on the parking garage frame, with a distance of no more than 3cm, the magnetic field strength will exceed 50uT. This will cause eddy current power loss of up to 500w. However, not all of this power loss will be converted into temperature rise. The conversion rate can be tested experimentally, and after multiple measurements, it can be taken as 5%, resulting in a temperature rise exceeding 45°C. The second relationship mentioned above is as follows:

[0042] Q = n*Pe (n is based on experimental test conversion efficiency)

[0043] It should be noted that due to different actual conditions at the primary and secondary sides of each wireless charging, the value of n may vary greatly, but the value of n can be determined through multiple experiments.

[0044] As an optional embodiment, the iron housing is used to absorb electromagnetic leakage, causing eddy current temperature rise in the temperature probe housing. The built-in temperature sensor senses the temperature, sends it to the temperature acquisition gateway, and transmits it to the cloud platform. The electromagnetic leakage value is inferred from the temperature measurement. The calculation process is as shown in the third relationship above:

[0045]

[0046] Where c is the specific heat capacity, Q is the thermal energy, m is the mass, and ΔT is the temperature rise. The temperature rise can be calculated using the third equation, and the electromagnetic leakage value can be calculated by combining the first and second equations above.

[0047] In an optional embodiment, determining the electromagnetic leakage of the wireless charging system based on the processing result includes: if the temperature rise value is greater than the preset threshold, determining that electromagnetic leakage occurs in the target location area.

[0048] In an embodiment of the present application, the eddy current heating of electromagnetic radiation is indirectly measured by a temperature sensor in an iron casing, and the electromagnetic leakage intensity is reversely deduced from the eddy current heating. This can qualitatively analyze the intensity of wireless leakage in the stereo garage to a certain extent. Expensive magnetic field metering equipment is not required, but the electromagnetic leakage intensity is indirectly monitored by temperature measuring equipment.
