Abstract
Description
Technical Field
[0001] This invention relates to the field of grounding wire technology, and in particular to a non-contact proximity autonomous early warning device, method and equipment based on electric field induction. Background Technology
[0002] When installing temporary grounding wires for power outage maintenance of overhead distribution lines, a voltage tester is used to check for voltage before the grounding wire is installed. This creates a time interval. If a "reverse power supply" or "power supply" occurs during this time, the workers are at high risk of electric shock and death, posing a safety hazard.
[0003] In existing technology, a voltage detector is installed on a grounding rod to sense the current in the high-voltage power line. When no current is detected, the grounding rod is directly hung on the high-voltage power line using a hook. The real-time voltage detection during the hanging process adopts a non-contact voltage detection principle based on the induction of electric field strength. This principle determines whether there is current in the high-voltage power line by comparing the electric field strength of the current voltage detection line with a fixed electric field strength threshold.
[0004] However, when the electric field strength of the voltage testing line is weak or the voltage detector installed on the grounding rod malfunctions, the existing non-contact voltage testing scheme may falsely report no current, and the accuracy of voltage testing needs to be improved. Summary of the Invention
[0005] This invention provides a non-contact proximity autonomous early warning device, method, and equipment based on electric field induction, which solves the technical problem that the accuracy of existing non-contact voltage detection schemes still needs to be improved.
[0006] The first aspect of the present invention provides a non-contact proximity autonomous early warning device based on electric field induction, comprising a non-contact voltage detection module, a data processing module, and an alarm module connected in series;
[0007] The non-contact voltage detection module is equipped with different electric field strength threshold levels. When the non-contact voltage detection module is close to the line to be tested, it is used to detect the electric field strength of the line to be tested, and when the detected electric field strength is not lower than the electric field strength threshold corresponding to the current electric field strength threshold level, it outputs a high-level signal to the data processing module.
[0008] The data processing module is used to drive the alarm module to output a first warning message based on the high-level signal, so as to warn that the line under test has a risk of being energized at a risk level corresponding to the current electric field strength threshold.

[0011] According to one embodiment of the first aspect of the present invention, the preset electric field strength threshold adjustment program is as follows:
[0012] The highest electric field strength threshold among the different electric field strength threshold levels is taken as the initial electric field strength threshold level.
[0013] Obtain the current electric field strength of the circuit to be tested;
[0014] If the current electric field strength is lower than the electric field strength threshold corresponding to the current electric field strength threshold level, the current electric field strength threshold level is lowered by one level and the previous step is returned until the level adjustment stop condition is met; the level adjustment stop condition is that the detected electric field strength is not lower than the electric field strength threshold corresponding to the current electric field strength threshold level, or the current electric field strength threshold level is the lowest electric field strength threshold level.
[0015] According to one achievable method of the first aspect of the present invention, the data processing module includes an STM32F103 chip;
[0016] The input pins of the STM32F103 chip are connected to the non-contact voltage detection module, and the output pins of the non-contact voltage detection module are connected to the alarm module.
[0017] According to one embodiment of the first aspect of the present invention, the non-contact proximity autonomous early warning device further includes a BeiDou and GPS dual-mode positioning module connected to the data processing module;
[0018] The Beidou and GPS dual-mode positioning module is used to acquire the satellite positioning information of the power line to be tested and send it to the data processing module;
[0019] The data processing module is also used to perform a secondary confirmation operation to confirm whether the line under test carries current. The secondary confirmation operation is as follows: obtaining the corresponding precise positioning data coordinates according to the satellite positioning information, sending the precise positioning data coordinates to the background line management system of the line under test, receiving the power supply data of the precise positioning data coordinates fed back by the background line management system, and, when the power supply data indicates that current is being supplied at the location of the precise positioning data coordinates, driving the alarm module to output a second warning message to warn that the line under test has a risk of being energized.
[0020] According to one achievable method of the first aspect of the present invention, the data processing module is specifically configured to perform the secondary confirmation operation when the risk level is lower than a preset level threshold, or to perform the secondary confirmation operation when the detected electric field strength is lower than the electric field strength threshold corresponding to the current electric field strength threshold level.

[0022] Determine the target electric field strength threshold from a set of multiple preset electric field strength thresholds, and obtain the target electric field strength threshold corresponding to the target electric field strength threshold.
[0023] Detect the electric field strength of the circuit to be tested;
[0024] The detected electric field strength is compared with the target electric field strength threshold;
[0025] When the detected electric field strength is not lower than the target electric field strength threshold, a first warning message is output to warn that the line under test has a risk of being energized at a risk level corresponding to the target electric field strength threshold.
[0026] According to one achievable embodiment of the second aspect of the invention, the method further includes:

[0030] Receive power supply data from the precise location coordinates fed back by the background line management system;
[0031] When the power supply data indicates that current is being transmitted at the location indicated by the precise positioning data coordinates, a second warning message is output to warn that the power line under inspection is at risk of being energized.
[0032] A third aspect of the present invention provides a non-contact proximity autonomous early warning device based on electric field induction, comprising:

[0045] This invention provides a non-contact proximity autonomous early warning device, method, and equipment based on electric field induction, which addresses the technical problem that the accuracy of existing non-contact voltage detection schemes still needs to be improved.
[0046] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.
[0047] This invention provides a non-contact proximity autonomous early warning device based on electric field induction.
[0048] Please see Figure 1 , Figure 1 The diagram shows a structural connection block diagram of a non-contact proximity autonomous early warning device based on electric field induction provided by an embodiment of the present invention.
[0049] This invention provides a non-contact proximity autonomous early warning device based on electric field induction, comprising a non-contact voltage detection module 1, a data processing module 2, and an alarm module 3 connected together;
[0050] The non-contact voltage testing module 1 is equipped with different electric field strength threshold levels; when the non-contact voltage testing module 1 is close to the line to be tested, it is used to detect the electric field strength of the line to be tested, and when the detected electric field strength is not lower than the electric field strength threshold corresponding to the current electric field strength threshold level, it outputs a high-level signal to the data processing module 2;
[0051] The data processing module 2 is used to drive the alarm module 3 to output a first warning message based on the high-level signal, so as to warn that the line under test has a risk of being energized at a risk level corresponding to the current electric field strength threshold.
[0052] In this embodiment, the non-contact voltage detection module 1 uses the principle of electromagnetic field induction to sense the electric field strength of the circuit. It should be noted that sensing the electric field strength of the circuit based on the principle of electromagnetic field induction is existing technology, and this embodiment does not limit it.
[0053] It should be noted that in this embodiment, the electric field strength threshold for a higher threshold level is greater than the electric field strength threshold for a lower threshold level.
[0054] In practical use, maintenance personnel bring the non-contact proximity autonomous early warning device close to the line to be tested and use the device to detect the electric field strength of the line. If the detected electric field strength is not lower than the electric field strength threshold corresponding to the current electric field strength threshold setting, the maintenance personnel will receive the first warning message. If the first warning message is not received, the maintenance personnel can lower the current electric field strength threshold setting to reduce the device's voltage detection sensitivity and then perform voltage detection on the line again.
[0055] In this embodiment of the invention, the sensitivity of voltage detection can be reduced by adjusting the electric field strength threshold, which helps to avoid the situation where no warning is given due to the weak electric field strength of the circuit to be tested, thereby improving the accuracy of voltage detection.
[0056] In one feasible manner, the non-contact voltage detection module 1 is provided with a range adjustment unit for adjusting the electric field strength threshold range.
[0057] The adjustment modes of the gear adjustment unit include manual adjustment mode and automatic adjustment mode; in the automatic adjustment mode, the gear adjustment unit adjusts the electric field strength threshold gear based on a preset electric field strength threshold gear adjustment program.
[0058] When the adjustment mode of the gear adjustment unit is manual adjustment mode, as a specific implementation, the gear adjustment unit may include a gear adjustment knob, so that maintenance personnel can adjust the gear adjustment knob to set the current electric field strength threshold gear of the device.
[0059] When the adjustment mode of the gear adjustment unit is manual, as another specific implementation, the gear adjustment unit may include an intelligent gear adjuster. This intelligent gear adjuster can set the current electric field strength threshold level of the device by receiving gear adjustment commands input by maintenance personnel. To facilitate the input of these gear adjustment commands by maintenance personnel, the intelligent gear adjuster may be equipped with a corresponding interactive interface or application.
[0060] In manual adjustment mode, if the first warning message is not received, maintenance personnel can manually lower the current electric field strength threshold to reduce the voltage detection sensitivity of the device, and then perform voltage detection on the line again.
[0061] In a specific implementation, the gear adjustment unit may include a mode switching button, thereby switching the adjustment mode based on the mode switching button. Alternatively, the gear adjustment unit may receive an adjustment mode switching command through an interactive interface or application, thereby adjusting to the corresponding adjustment mode based on the adjustment mode switching command.
[0062] In one feasible approach, the preset electric field strength threshold adjustment program is as follows:
[0063] The highest electric field strength threshold among the different electric field strength threshold levels is taken as the initial electric field strength threshold level.
[0064] Obtain the current electric field strength of the circuit to be tested;
[0065] If the current electric field strength is lower than the electric field strength threshold corresponding to the current electric field strength threshold level, the current electric field strength threshold level is lowered by one level and the previous step is returned until the level adjustment stop condition is met; the level adjustment stop condition is that the detected electric field strength is not lower than the electric field strength threshold corresponding to the current electric field strength threshold level, or the current electric field strength threshold level is the lowest electric field strength threshold level.
[0066] The preset electric field strength threshold adjustment program enables the device to intelligently adjust the electric field strength threshold in descending order when testing the line under test. This allows the device to determine whether the line under test is at risk of being energized based on the electric field strength threshold corresponding to different threshold levels, thus achieving intelligent adjustment of the device's voltage detection sensitivity.
[0067] It should be noted that when setting the electric field strength threshold adjustment program, in addition to lowering the current electric field strength threshold by one level, other adjustment step values can also be set. For example, if the obtained current electric field strength is lower than the electric field strength threshold corresponding to the current electric field strength threshold, the current electric field strength threshold will be lowered by two levels.
[0068] In one feasible implementation, the data processing module 2 includes an STM32F103 chip;
[0069] The input pin of the STM32F103 chip is connected to the non-contact voltage detection module 1, and the output pin of the non-contact voltage detection module 1 is connected to the alarm module 3.
[0070] In one feasible way, Figure 1 Based on the device shown, such as Figure 2 As shown, the non-contact near-electric autonomous early warning device also includes a Beidou and GPS dual-mode positioning module 4 connected to the data processing module 2;
[0071] The Beidou and GPS dual-mode positioning module 4 is used to acquire the satellite positioning information of the power line to be tested and send it to the data processing module 2;
[0072] The data processing module 2 is also used to perform a secondary confirmation operation to confirm whether the line under test carries current. The secondary confirmation operation is as follows: obtaining the corresponding precise positioning data coordinates according to the satellite positioning information, sending the precise positioning data coordinates to the background line management system of the line under test, receiving the power supply data of the precise positioning data coordinates fed back by the background line management system, and, when the power supply data indicates that current is being supplied at the position of the precise positioning data coordinates, driving the alarm module 3 to output a second warning message to warn that the line under test has a risk of being energized.
[0073] Specifically, the Beidou and GPS dual-mode positioning module 4 acquires satellite positioning information through a satellite antenna and connects to the data processing module 2 through the first serial port interface. The data processing module 2 transmits the satellite positioning information to the precise positioning service platform through the second serial port interface. After calculation, the precise positioning service platform returns the precise positioning location data coordinates, which include both horizontal and vertical precise positioning location data coordinates.
[0074] It should be noted that the precise positioning service platform and the back-end route management system are existing platform systems, and this embodiment does not limit them.
[0075] In the first usage mode, when the alarm module 3 outputs the first warning message and the second warning message, it can be determined that the circuit to be tested carries current; when the alarm module 3 only outputs the first warning message or the second warning message, it can be determined that the circuit to be tested may carry current; when the alarm module 3 does not output the first warning message or the second warning message, it can be determined that the circuit to be tested does not carry current.
[0076] As a second usage method, when the risk level of the liveness risk in the first warning message output by the alarm module 3 is higher than the preset risk level threshold, or when the alarm module 3 outputs the first warning message and the second warning message, it can be determined that the circuit to be tested carries current; when the risk level of the liveness risk in the first warning message output by the alarm module 3 is not higher than the preset risk level threshold, but the alarm module 3 also outputs the second warning message, it can be determined that the circuit to be tested may carry current; when the alarm module 3 only outputs the first warning message or the second warning message, it can be determined that the circuit to be tested may carry current; when the alarm module 3 does not output the first warning message or the second warning message, it can be determined that the circuit to be tested does not carry current.
[0077] It should be noted that the above usage method can be determined according to the actual voltage testing requirements, and any of the above usage methods can also be adjusted according to the actual voltage testing requirements.
[0078] In this embodiment, based on the power supply data of the precise positioning coordinates fed back by the background line management system, it is determined again whether the line to be tested carries current. This can avoid the situation where the line to be tested carries current but no warning or false alarm is given due to the failure of the non-contact power testing module 1, which is beneficial to improving the accuracy of power testing.
[0079] In one feasible manner, the data processing module 2 is specifically used to perform the secondary confirmation operation when the risk level is lower than a preset level threshold, or to perform the secondary confirmation operation when the detected electric field strength is lower than the electric field strength threshold corresponding to the current electric field strength threshold level.
[0080] In this embodiment, a trigger restriction is set for performing the secondary confirmation operation, which can be applied to the second usage method described above. This trigger restriction reduces the workload of the data processing module 2 and avoids unnecessary secondary confirmation operations on the voltage testing results.
[0081] In one feasible implementation, the alarm module 3 is an audible and visual warning device. This device can output a first warning message and / or a second warning message using flashing blue and red lights and voice broadcasting.
[0082] It should be noted that the alarm module 3 can also be other existing devices that can be used to indicate whether there is a risk of energization in the voltage testing circuit.
[0083] Furthermore, the non-contact proximity autonomous early warning device based on electric field induction may also include a battery power management module to enable power supply and power management for the remaining modules of the device.
[0084] Furthermore, the non-contact proximity autonomous early warning device based on electric field induction may also include a communication module to enable communication between the other modules of the device and communication between the other modules of the device and external entities (including the precise positioning service platform and the background line management system).
[0085] To facilitate voltage testing by maintenance personnel using the device described in this application, the non-contact voltage testing module 1 can be installed at the grounding clamp. Furthermore, the grounding clamp can be connected to an insulating rod. The length of the insulating rod can be adjusted by extending or retracting it to meet the needs of hanging / removing the grounding wire over a greater distance, allowing maintenance personnel to perform the hanging / removing operation without climbing.

[0087] Please see Figure 3 , Figure 3 A flowchart of a non-contact proximity autonomous early warning method based on electric field induction provided by an embodiment of the present invention is shown.
[0088] The present invention provides a non-contact proximity autonomous early warning method based on electric field induction, comprising steps S1-S4.
[0089] Step S1: Determine the target electric field strength threshold from a set of multiple preset electric field strength thresholds, and obtain the target electric field strength threshold corresponding to the target electric field strength threshold.
[0090] Step S2: Detect the electric field strength of the circuit to be tested;
[0091] Step S3: Compare the detected electric field strength with the target electric field strength threshold;
[0092] Step S4: When the detected electric field strength is not lower than the target electric field strength threshold, output the first warning message to warn that the line under test has a risk of being energized at a risk level corresponding to the target electric field strength threshold.
[0093] The method for determining the target electric field strength threshold from multiple preset electric field strength thresholds can be found in the description of the manual adjustment mode and automatic adjustment mode in the above-described embodiment of the non-contact proximity autonomous early warning device based on electric field induction, which will not be repeated here.

[0095] Step S5: Obtain the satellite positioning information of the power line to be tested;
[0096] Step S6: Obtain the corresponding precise positioning location data coordinates based on the satellite positioning information;
[0097] Step S7: Send the precise location data coordinates to the background line management system of the power line to be tested;
[0098] Step S8: Receive power transmission data of the precise location coordinates fed back by the background line management system;
[0099] Step S9: When the power supply data indicates that current is being transmitted at the location indicated by the precise positioning data coordinates, a second warning message is output to warn that the power line under test is at risk of being energized.
[0100] Specifically, step S5 can be performed when the risk level is lower than a preset level threshold, or step S5 can be performed when the detected electric field strength is lower than the target electric field strength threshold.
