[0048] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0049] Reference Figure 1 , Figure 1 It is a structural block diagram of the first embodiment of the electric field monitoring system of the present invention.

[0050] In this embodiment, the electric field monitoring system includes a detection device 10, a digital twin module 20, an electric field monitoring module 30, a detection control module 40 and a ground management module 50, and the digital twin module 20 and the electric field monitoring module 30 are mounted on the detection device 10.

[0051] It should be noted that the digital twin module 20 is used to obtain three-dimensional environmental parameters and send the three-dimensional environmental parameters to the detection control module 40; the electric field monitoring module 30 is used to perform comprehensive electric field measurement on the detection area to obtain target monitoring data, and send the target monitoring data to the detection control module 40; the detection control module 40 is used to send detection instructions to the detection equipment 10, and send the three-dimensional environmental parameters and the target monitoring data to the ground management module 50; the ground management module 50 is used to perform data analysis based on the three-dimensional environmental parameters and the target monitoring data to obtain the electric field monitoring curve; the detection equipment 10 is used to perform flight detection according to the detection instructions, so that the data twin module 20 and the electric field monitoring module 30 can collect data.

[0052] It can be understood that the digital twin module 20 and the electric field monitoring module 30 on the electric field monitoring system are mounted on the detection device 10. The detection device 10 can be a drone or other flying device. The flight of the detection device 10 enables the digital twin module 20 and the electric field monitoring module 30 to measure the surrounding data of the electric field environment.

[0053] In the specific implementation, the digital twin module 20 digitally reconstructs the system structures such as lines and towers in the area to be detected by scanning, and maps the three-dimensional structure of the entity in the digital space, so as to obtain the three-dimensional model parameters of the conductors, towers, insulators, hardware, and channel environment in the area to be detected, and uses the three-dimensional model parameters of the conductors, towers, insulators, hardware, and channel environment in the area to be detected as three-dimensional environmental parameters, and sends the three-dimensional environmental parameters to the detection control module 40.

[0054] It should be noted that the electric field monitoring module 30 can adopt a field mill type electric field monitor. The electric field monitoring module 30 measures the DC synthetic field and the industrial frequency electric field, and realizes the comprehensive measurement of the spatial AC electric field by measuring and calculating the components in the three directions of X, Y, and Z. The field mill rotates to realize the DC synthetic electric field measurement, thereby obtaining the corresponding target monitoring data, and sending the target monitoring data to the detection control module 40.

[0055] It can be understood that the detection control module 40 includes a flight control unit and a wireless communication unit. The flight control unit can send detection instructions to the detection equipment. The wireless communication unit receives the three-dimensional environmental parameters of the digital twin module and the target monitoring data of the electric field monitoring module, and sends the three-dimensional environmental parameters and target monitoring data to the ground management module 50.

[0056] In a specific implementation, the wireless communication unit in the detection control module 40 receives the three-dimensional environmental parameters of the digital twin module 20 and the target monitoring data of the electric field monitoring module 30 , and sends the three-dimensional environmental parameters and the target monitoring data to the ground management module 50 .

[0057] It should be noted that the flight control unit in the detection control module 40 sets the electric field threshold according to the corresponding relationship between the electromagnetic field strength of the area to be detected and the distance to the wire, obtains the preset positioning point of the detection device, and the preset positioning point is pre-set by the ground management module 50. At the same time, the detection height, detection attitude and detection path of the detection device 10 are determined according to the preset positioning point, and the detection instruction is generated according to the detection height, detection attitude and detection path, and the detection instruction is sent to the detection device 10, so that the detection device 10 performs detection according to the detection instruction. At the same time, when the detection device 10 is too close to the wire during the detection process, resulting in the measured electric field value being greater than the threshold, the ground management module 50 determines that the detection device is in a dangerous flight area, and the flight control unit issues a warning to prompt the detection device 10 control personnel to adjust the detection attitude and height of the detection device until the alarm signal disappears, so as to ensure the safe flight of the detection device.

[0058] It is understandable that after receiving the three-dimensional environmental parameters and the target monitoring data, the ground management module 50 performs data analysis on the two to obtain the electric field monitoring curve.

[0059] In a specific implementation, the ground management module 50 converts the digital signal of the target monitoring data into an analog signal through the internal D / A conversion circuit, decompresses and reproduces the analog current signal, and converts it into an electric field value signal through the current and electric field conversion relationship, thereby obtaining each collection point and the first electric field value corresponding to the collection point. The trend analysis unit in the ground management module 50 draws the first electric field distribution curve according to the collection point and the first electric field value corresponding to the collection point, and obtains the electric field distribution trend of the area to be detected.

[0060] It should be noted that the ground management module 50 constructs a three-dimensional model of the tower line space and a channel environment entity model of the area to be detected by inputting three-dimensional environmental parameters into the electric field simulation calculation model, sets electric field calculation boundary conditions, loads operating voltage, sets the initial value of ion flow density, calculates the industrial frequency electric field and DC synthetic field through the finite element method, and draws the electric field distribution values ​​at sensitive points such as specific observation paths and houses under the lines. Sensitive points such as specific observation paths and houses under the lines are environmental points, and the electric field distribution values ​​corresponding to the environmental points are the second electric field values. A second electric field curve is drawn according to the environmental points and the second electric field values ​​corresponding to the environmental points, and an electric field monitoring curve is obtained according to the first electric field curve and the second electric field curve.

[0061] It is understandable that the detection device 10 can be a drone or other flying equipment, and this embodiment does not limit this. The support rod of the detection device adopts a silicone rubber umbrella skirt outer sheath, with three umbrella skirts in the middle to achieve accurate measurement under high humidity conditions. The support rod shaft is connected to the motor rotation shaft to achieve flexible adjustment of the rotation direction. The rotating structure is used to adjust the direction of the probe to ensure that the electric field measurement result is consistent with the maximum value direction. The electric field monitoring module is symmetrically arranged at the end of the support rod, and the center of the device is spaced 2m apart. By adjusting the detection path of the detection device 10, the electric field measurement of a section of the offline space in the area to be detected can be achieved.

[0062] In the specific implementation, Figure 2 The figure shows the overall structure of the electric field monitoring system. The electric field monitoring module and the digital twin module are mounted on the detection equipment. The electric field monitoring module sends the target monitoring data to the wireless communication unit in the detection control module. The digital twin module sends the three-dimensional environmental parameters to the wireless communication unit. The flight control unit in the detection control module issues detection instructions to the detection equipment. At the same time, the wireless communication unit sends the target monitoring data and three-dimensional environmental parameters to the ground management module, so that the ground management module can complete the data monitoring of the electric field environment.

[0063] In this embodiment, the electric field monitoring system includes a detection device, a digital twin module, an electric field monitoring module, a detection control module and a ground management module, wherein the digital twin module and the electric field monitoring module are mounted on the detection device; the digital twin module is used to obtain three-dimensional environmental parameters and send the three-dimensional environmental parameters to the detection control module; the electric field monitoring module is used to perform comprehensive electric field measurement on the detection area to obtain target monitoring data, and send the target monitoring data to the detection control module; the detection control module is used to send detection instructions to the detection device, and send the three-dimensional environmental parameters and the target monitoring data to the ground management module; the ground management module is used to perform data analysis based on the three-dimensional environmental parameters and the target monitoring data to obtain an electric field monitoring curve; the detection device is used to perform flight detection according to the detection instructions, so that the data twin module and the electric field monitoring module can collect data. The detection control module issues detection instructions, and the detection equipment performs flight detection based on the detection instructions, enabling the digital twin module and electric field monitoring module on the detection equipment to obtain corresponding parameters and data. The parameters and data are processed through the ground management module to obtain the electric field monitoring curve corresponding to the electric field environment. This reduces labor intensity while improving monitoring efficiency, realizes all-round monitoring of the electric field environment, and improves the accuracy of monitoring data.

[0064] Reference Figure 3 , Figure 3 1 is a structural block diagram of a second embodiment of an electric field monitoring system of the present invention. Based on the above first embodiment, the second embodiment of the electric field monitoring system of the present invention is proposed.

[0065] In this embodiment, the electric field monitoring module 30 is also used to perform comprehensive electric field measurement on the detection area to obtain initial monitoring data; perform data conversion on the initial monitoring data to obtain target monitoring data, and send the target monitoring data to the detection control module.

[0066] It should be noted that the electric field measurement module 30 can adopt a field mill type electric field monitor, and the electric field monitoring module measures the DC synthetic field and the industrial frequency electric field, and measures the components in the three directions of X, Y, and Z to obtain initial monitoring data.

[0067] It is understandable that the charge data or voltage data corresponding to the initial monitoring data is converted and analyzed to obtain the target monitoring data corresponding to the initial monitoring data, and the target monitoring data is sent to the detection control module 40 .

[0068] In a specific implementation, the charge data or voltage data in the initial monitoring data is converted into current data, and the current data is amplified by 2.43 times through a signal amplifier to obtain the first monitoring data. An active bandpass filter is used to perform bandpass filtering on the first monitoring data to eliminate stray and interference signals outside the preset frequency range to obtain the second monitoring data. At the same time, the interference anomaly and temperature drift in the second monitoring data are eliminated by the reset circuit, and the effective distinction between the power frequency component and the DC component and the direct conversion of the input and output signals are achieved, and the second monitoring data is output after the analog-to-digital conversion is achieved through the 12-bit A / D conversion circuit. In order to eliminate the interference source of the signal acquisition circuit, the control circuit is shielded and isolated by switching the photoelectric coupler, and the target monitoring data is obtained after the second monitoring data is compressed, and the target monitoring data is sent to the detection control module 40. The preset method refers to the processing method of the reset circuit and the 12-bit A / D conversion circuit.

[0069] The electric field monitoring module in this embodiment is also used to perform comprehensive electric field measurement on the detection area to obtain initial monitoring data; perform data conversion on the initial monitoring data to obtain target monitoring data, and send the target monitoring data to the detection control module. By analyzing and processing the initial monitoring data, accurate target monitoring data is obtained, which is conducive to subsequent electric field distribution trend analysis based on the target monitoring data.

[0070] Reference Figure 4 , Figure 4 This is a flow chart of a first embodiment of a control method for an electric field monitoring system according to the present invention. The control method for an electric field monitoring system includes:

[0071] Step S10: The digital twin module obtains three-dimensional environmental parameters and sends the three-dimensional environmental parameters to the detection control module.

[0072] It should be noted that the executor of this embodiment is the electric field monitoring system.

The detection equipment can be a drone or other flying equipment. The flight of the detection equipment enables the digital twin module and the electric field monitoring module to measure the surrounding data of the electric field environment. The digital twin module obtains the three-dimensional environmental parameters of the area to be detected, and sends the three-dimensional environmental parameters to the detection control module. The electric field monitoring module obtains the target monitoring data of the area to be detected, and sends the target monitoring data to the detection control module. The detection control module sends the detection instruction to the detection equipment, and at the same time sends the target monitoring data and the three-dimensional environmental parameters to the ground management module. The ground management module draws the electric field monitoring curve according to the target monitoring data and the three-dimensional environmental parameters.

[0073] It can be understood that the digital twin module digitally reconstructs the system structures such as lines and towers in the area to be detected by scanning, and maps the three-dimensional structure of the entity in the digital space, thereby obtaining the three-dimensional model parameters of the wires, towers, insulators, hardware, and channel environment in the area to be detected, and uses the three-dimensional model parameters of the wires, towers, insulators, hardware, and channel environment in the area to be detected as three-dimensional environmental parameters, and sends the three-dimensional environmental parameters to the detection control module.

[0075] It should be noted that the electric field monitoring module can adopt a field mill electric field monitor. The electric field monitoring module measures the DC synthetic field and the industrial frequency electric field. By measuring and calculating the components in the three directions of X, Y, and Z, the comprehensive measurement of the spatial AC electric field is realized.

The flight control unit can send detection instructions to the detection equipment. The wireless communication unit receives the three-dimensional environmental parameters of the digital twin module and the target monitoring data of the electric field monitoring module, and sends the three-dimensional environmental parameters and target monitoring data to the ground management module.

[0078] It can be understood that in order to obtain accurate detection instructions according to the environment of the area to be detected, the detection control module further sends the detection instructions to the detection device, including: obtaining a preset positioning point; determining the detection height, detection posture and detection path according to the preset positioning point; generating the detection instruction according to the detection height, detection posture and detection path, and sending the detection instruction to the detection device.

At the same time, the detection height, detection attitude and detection path of the detection device are determined according to the preset positioning point, and the detection instruction is generated according to the detection height, detection attitude and detection path, and the detection instruction is sent to the detection device so that the detection device performs detection according to the detection instruction. At the same time, when the detection device is too close to the wire during the detection process, resulting in the measured electric field value being greater than the threshold, the ground management module determines that the detection device is in a dangerous flight area, and the flight control unit issues a warning to prompt the detection device control personnel to adjust the detection attitude and height of the detection device until the alarm signal disappears, so as to ensure the safe flight of the detection device.
