These problems result in existing mineral detection methods being inefficient, costly, and unable to meet the demand for rapid and accurate mineral detection. Summary of the Invention

[0004] In view of this, this application provides a method, apparatus, electronic device and storage medium for rapid mineral detection with a predetermined interference threshold, which can improve the efficiency and accuracy of mineral detection and reduce the cost of mineral detection.

[0011] In one possible implementation, if it is determined that the mineral exists in the area to be detected, determining the type of the mineral includes: detecting whether a target interference threshold interval exists among a plurality of interference threshold intervals, wherein the target interference value is within the target interference threshold interval; if the target interference threshold interval is detected, determining that the mineral exists in the area to be detected, and taking the sample mineral type corresponding to the target interference threshold interval as the type of the mineral.

[0029] Broadcast signal receiving equipment: used to receive the original broadcast signal from broadcast satellites as well as the broadcast signal after interference from underground mineral deposits. This equipment can be a common satellite signal receiving antenna, with high sensitivity and wide bandwidth reception capability, capable of accurately capturing the broadcast signal and its changes after interference.

[0030] Please refer to Figure 1 , Figure 1 This is a flowchart illustrating the steps of an embodiment of the rapid mineral detection method with a predetermined interference threshold according to this application. The order of the steps in this flowchart can be changed, and some steps can be omitted, depending on different requirements. The rapid mineral detection method with a predetermined interference threshold of this application can be applied to rapid mineral detection devices with predetermined interference thresholds, but is not limited thereto, and the embodiments of this application do not limit this application.

[0031] The specific process of this embodiment is as follows: Figure 1 As shown, it includes the following steps:

[0032] Step 101: Receive the first wireless signal and the second wireless signal, wherein the first wireless signal is the original signal sent by the signal transmitting device, and the second wireless signal is the signal after the original signal has been interfered with by the area to be detected.

[0033] In some embodiments, the signal transmitting device is a satellite, and the original signal is a broadcast signal transmitted by the satellite. Broadcast signals have the characteristics of wide coverage, stable signal, and easy reception. By setting the original signal to a broadcast signal, the accuracy of the first and second characteristic physical quantities calculated subsequently based on the first and second wireless signals can be improved, thereby improving the accuracy of the target interference value calculated using the first and second characteristic physical quantities, and further improving the accuracy of determining whether minerals exist in the area to be detected using the target interference value.

[0034] In some embodiments, the mineral rapid detection device with a predetermined interference threshold includes a broadcast signal receiving device, through which a first wireless signal and a second wireless signal are received.

[0035] To facilitate understanding, the following will be combined with... Figure 2 This embodiment provides a detailed explanation of how the first and second wireless signals are received:

[0036] Please refer to Figure 2This is a schematic diagram illustrating an application scenario for signal reception provided in this application embodiment. A broadcast signal receiving device is placed in the area to be detected in the mine, and the direction and angle of the antenna are adjusted to enable it to receive a clear broadcast signal. The broadcast signal receiving device simultaneously receives a first wireless signal and a second wireless signal, and converts them into electrical signals.

[0037] Step 102: Extract features from the first wireless signal and the second wireless signal respectively to obtain the first feature physical quantity of the first wireless signal and the second feature physical quantity of the second wireless signal.

[0038] In some embodiments, the first characteristic physical quantity includes: the first average signal strength, the first average frequency offset, the first average phase change, and the first average signal bandwidth of the first wireless signal; the second characteristic physical quantity includes: the second average signal strength, the second average frequency offset, the second average phase change, and the second average signal bandwidth of the second wireless signal.

[0039] Specifically, the rapid mineral detection device with a predetermined interference threshold includes a signal processing module, which in turn includes a signal analysis circuit. The broadcast signal receiving device in the aforementioned steps converts both the first and second wireless signals into electrical signals, and then sends the converted electrical signals to the signal processing module. The signal analysis circuit of the signal processing module extracts characteristic physical quantities of the electrical signals, such as frequency, amplitude, and phase.

[0040] In some embodiments, before the signal processing module extracts features from the first and second wireless signals, it also performs filtering on the first and second wireless signals to remove noise interference, thereby further improving the accuracy of the subsequently calculated target interference value.

[0041] Step 103: Calculate the target interference value based on the first characteristic physical quantity and the second characteristic physical quantity. The target interference value is used to characterize the degree of influence of the area to be detected on the original signal.

[0042] In some embodiments, the target interference value can be calculated by: calculating a first difference between the first average signal strength and the second average signal strength, a second difference between the first average frequency offset and the second average frequency offset, a third difference between the first average phase change and the second average phase change, and a fourth difference between the first average signal bandwidth and the second average signal bandwidth; and calculating the target interference value based on the first difference, the second difference, the third difference, and the fourth difference.

[0043] Specifically, a first weight corresponding to the average signal strength, a second weight corresponding to the average frequency offset, a third weight corresponding to the average phase change, and a fourth weight corresponding to the average signal bandwidth are determined, wherein the sum of the first weight, the second weight, the third weight, and the fourth weight is equal to 1; the first product of the first weight and the first difference, the second product of the second weight and the second difference, the third product of the third weight and the third difference, and the fourth product of the fourth weight and the fourth difference are calculated respectively; the sum of the first product, the second product, the third product, and the fourth product is taken as the target interference value.

[0044] To facilitate understanding, the following is a detailed explanation of how the target interference value is calculated in this embodiment:

[0045] 1. Assume that the average first signal strength of the received first wireless signal is St=50dBm, the average first frequency offset is Ft=10Hz, the average first phase change is Pt=30°, and the average first signal bandwidth is Bt=20kHz; the average second signal strength of the received second wireless signal is Sr=60dBm, the average second frequency offset is Fr=2Hz, the average second phase change is Pr=10°, and the average second signal bandwidth is Br=15kHz.

[0046] 2. Calculate the differences of each characteristic physical quantity: signal strength difference ΔS = |50−60| = 10dBm; frequency offset difference ΔF = |10−2| = 8Hz; phase change difference ΔP = |30−10| = 20°; signal bandwidth difference ΔB = |20−15| = 5kHz.

[0047] 3. Set weights: the first weight for signal strength is wS=0.3, the second weight for frequency offset is wF=0.3, the third weight for phase change is wP=0.2, and the fourth weight for signal bandwidth is wB=0.2.

[0048] It is worth noting that, since different minerals have different degrees of influence on each characteristic physical quantity, this embodiment can set different first weights, second weights, third weights and fourth weights according to different mineral types.

[0049] 4. Calculate the target interference value T: T = 0.3 × 10 + 0.3 × 8 + 0.2 × 20 + 0.2 × 5 = 10.4.

[0050] It should also be noted that this embodiment illustrates the calculation of target interference value by difference calculation. In practical applications, target interference value can also be calculated by ratio calculation or other methods. The appropriate calculation method can be selected according to different signal characteristics.

[0051] Step 104: Determine whether there are minerals in the area to be detected based on the target interference value, and if it is determined that there are minerals in the area to be detected, determine the type of minerals.

[0052] The method for determining whether minerals exist in the area to be detected based on the target interference value is described in detail in subsequent embodiments, and will not be repeated here to avoid repetition.

[0053] Compared with related technologies, the embodiments of this application have at least the following advantages: Since the first wireless signal is the original signal transmitted by the signal transmitting device, and the second wireless signal is the signal after the original signal has been interfered with by the area to be detected, by extracting features from the first and second wireless signals respectively to obtain the first and second characteristic physical quantities, and then calculating the target interference value using the first and second characteristic physical quantities, the degree of influence of the area to be detected on the original signal can be characterized. Furthermore, since the degree of influence varies depending on the type of mineral in the area to be detected, that is, when different types of minerals exist in the area to be detected, the received second wireless signal is different, and the second characteristic physical quantity calculated based on the second wireless signal is different. Therefore, the presence of minerals in the area to be detected can be determined based on the magnitude of the target interference value, and the type of mineral can be determined based on the magnitude of the target interference value. The aforementioned rapid mineral detection method with a predetermined interference threshold eliminates the need for complex field surveys, sampling, and analysis. Simply receiving the first and second wireless signals and performing basic signal processing yields results quickly, significantly improving detection efficiency. Furthermore, the target interference value accurately identifies the type of mineral deposit, reducing interference from topography and geological conditions and enhancing the accuracy of mineral detection. Moreover, this rapid mineral detection method with a predetermined interference threshold can be implemented using existing signal receiving and transmitting equipment, eliminating the need for expensive specialized geophysical exploration equipment and reducing both equipment and detection costs. Simultaneously, it reduces manpower and fieldwork time, further lowering costs.

[0054] Please refer to Figure 3 , Figure 3 This is a flowchart illustrating the steps of an embodiment of the rapid mineral detection method with a predetermined interference threshold according to this application. The order of the steps in this flowchart can be changed, and some steps can be omitted, depending on different requirements. This rapid mineral detection method with a predetermined interference threshold can be applied to the aforementioned rapid mineral detection device with a predetermined interference threshold, but is not limited thereto, and the embodiments of this application do not limit it in this regard.

[0055] This embodiment is a detailed description of the foregoing embodiments, mainly illustrating how to determine whether minerals exist within the area to be detected based on target interference values, and how to determine the type of minerals when their presence is confirmed. This method further ensures the accuracy of mineral detection.

[0056] The specific process of this embodiment is as follows: Figure 3 As shown, it includes the following steps:

[0057] Step 201: Receive a first wireless signal and a second wireless signal, wherein the first wireless signal is the original signal sent by the signal transmitting device, and the second wireless signal is the signal after the original signal has been interfered with by the area to be detected.

[0058] Step 202: Extract features from the first wireless signal and the second wireless signal respectively to obtain the first feature physical quantity of the first wireless signal and the second feature physical quantity of the second wireless signal.

[0059] Step 203: Calculate the target interference value based on the first characteristic physical quantity and the second characteristic physical quantity. The target interference value is used to characterize the degree of influence of the area to be detected on the original signal.

[0060] Steps 201 to 203 in this embodiment are similar to steps 101 to 103 in the previous embodiment. To avoid repetition, they will not be described again here.

[0061] Step 204: Compare the target interference value with multiple preset interference threshold ranges, determine whether there are minerals in the area to be detected based on the comparison results, and determine the type of minerals if minerals are found in the area to be detected.

[0062] Specifically, the interference threshold range is used to characterize the degree of influence of the sample region containing minerals on the original signal. Different types of sample minerals in the sample region correspond to different interference threshold ranges.

[0063] In some embodiments, the interference threshold range can be determined as follows:

[0064] 1. Conduct signal acquisition in multiple standard test areas where the target mineral (such as iron ore) is known to exist and in reference areas where iron ore is not present. Acquire signals multiple times in each area and record characteristic physical quantities such as signal strength, frequency shift, phase change, and signal bandwidth.

[0065] 2. Calculate the average value of each characteristic physical quantity in the standard test area and the reference area.

[0066] 3. Calculate the difference between the average values ​​of each characteristic physical quantity, set different weights for the characteristic physical quantities according to the degree of influence of different minerals on the characteristic physical quantities, and calculate the interference threshold range corresponding to different minerals.

[0067] In some embodiments, it is detected whether a target interference threshold interval exists among multiple interference threshold intervals, and the target interference value is within the target interference threshold interval; if the existence of a target interference threshold interval is detected, it is determined that there are minerals in the area to be detected, and the sample mineral type corresponding to the target interference threshold interval is taken as the mineral type.

[0068] It is worth noting that if multiple target interference threshold intervals are calculated, meaning the target interference value falls within multiple interference threshold intervals, it indicates the presence of multiple types of minerals in the area to be detected. If no target interference threshold interval exists, it is determined that no minerals exist in the area to be detected.

[0069] Compared with related technologies, the embodiments of this application have at least the following advantages: Since the first wireless signal is the original signal transmitted by the signal transmitting device, and the second wireless signal is the signal after the original signal has been interfered with by the area to be detected, by extracting features from the first and second wireless signals respectively to obtain the first and second characteristic physical quantities, and then calculating the target interference value using the first and second characteristic physical quantities, the degree of influence of the area to be detected on the original signal can be characterized. Furthermore, since the degree of influence varies depending on the type of mineral in the area to be detected, that is, when different types of minerals exist in the area to be detected, the received second wireless signal is different, and the second characteristic physical quantity calculated based on the second wireless signal is different. Therefore, the presence of minerals in the area to be detected can be determined based on the magnitude of the target interference value, and the type of mineral can be determined based on the magnitude of the target interference value. The aforementioned rapid mineral detection method with a predetermined interference threshold eliminates the need for complex field surveys, sampling, and analysis. Simply receiving the first and second wireless signals and performing basic signal processing yields results quickly, significantly improving detection efficiency. Furthermore, the target interference value accurately identifies the type of mineral deposit, reducing interference from topography and geological conditions and enhancing the accuracy of mineral detection. Moreover, this rapid mineral detection method with a predetermined interference threshold can be implemented using existing signal receiving and transmitting equipment, eliminating the need for expensive specialized geophysical exploration equipment and reducing both equipment and detection costs. Simultaneously, it reduces manpower and fieldwork time, further lowering costs.

The target interference value is used to characterize the degree of influence of the area to be detected on the original signal. The degree of influence varies depending on the type of mineral in the area to be detected.

[0075] The determination module 404 is used to determine whether there are minerals in the area to be detected based on the target interference value, and if it is determined that there are minerals in the area to be detected, to determine the type of minerals.

[0076] In some embodiments, the mineral rapid detection device 40 with a predetermined interference threshold may further include a display module and a storage module. The determination module 404 stores the determination result in the storage module and simultaneously sends the result to the display module for display. The storage module also stores the received signal data and the calculated target interference value for convenient subsequent data analysis and query. The display module presents the detection results in intuitive text and chart formats, such as "Iron ore present" and "No target mineral deposit found," for easy viewing and recording by operators.
