[0042] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0043] The electric shock warning method provided in this application embodiment can be applied to, for example... Figure 1The electric shock warning system shown includes a controller 110 and multiple detection devices 120. The controller 110 is installed in a special-operation vehicle, and the detection devices 120 are respectively installed around the vehicle. Each detection device 110 detects the first electric field strength and attitude information of its own location and sends this information to the controller 120. The controller 120 acquires the first electric field strength of each detection device 110, which describes the magnitude and direction of the electric field at the location of each detection device 110, wherein the electric field direction is determined based on the detection device's coordinate system. Based on the position and attitude information of each detection device 110 relative to the controller 120, the controller converts each first electric field strength into a corresponding second electric field strength, wherein the electric field direction in the second electric field strength is based on the controller's coordinate system.

This warning information instructs the operator to refrain from moving in the direction of the electric field in the second electric field strength when the magnitude of the second electric field strength does not meet the preset warning electric field strength. The controller 110 can be a computer device, including but not limited to various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices can include smart speakers, smart TVs, smart air conditioners, smart in-vehicle systems, and projection devices. Portable wearable devices can include smartwatches, smart bracelets, and head-mounted displays. Head-mounted displays can be virtual reality (VR) devices, augmented reality (AR) devices, and smart glasses.

[0044] In one exemplary embodiment, such as Figure 2 As shown, an electric shock warning method is provided for use in the controller of an electric shock warning system. The electric shock warning system includes a controller and multiple detection devices. The controller is installed in a special-operation vehicle, and the multiple detection devices are respectively installed around the special-operation vehicle. This method is applied to... Figure 1 The following steps, 201 to 203, are used as an example of the controller in the example.

[0045] S201, Obtain the first electric field strength of each detection device.

[0046] The first electric field strength is used to describe the electric field strength value and electric field direction at the location of each detection device, wherein the electric field direction is determined based on the coordinate system of the detection device.

[0047] Optionally, the detection device can be an electric field strength detection device that can measure the electric field strength in space.

[0048] In one possible implementation, the detection device can rely on the principle of charge induction, placing a measuring capacitor inside the sensor. The electric field in space causes a change in voltage or charge across the capacitor, which can then be used to calculate the electric field strength.

[0049] In another possible implementation, the detection device may include a probe consisting of a rotatable shielding blade and a fixed sensing blade. The shielding blade can rotate at high speed, causing the exposed area of ​​the sensing blade in the DC electric field to change periodically, thereby generating an alternating induced current signal. The DC electric field strength is determined by detecting this alternating induced current signal.

[0050] Optionally, the electric field strength detection device may include a high-frequency near-field electromagnetic field strength meter, a power frequency (near-field) field strength meter, and a novel microelectromechanical system silicon-based sensor, etc. The embodiments of this application do not limit the type of electric field strength detection device.

[0051] Optionally, the controller can communicate with the electric field strength detection device via wired connection, wireless communication, fiber optic communication, or other communication protocols. After determining the first electric field strength, the electric field strength detection device can send the first electric field strength to the controller. Wired communication can be a direct connection between the electric field strength detection device and the controller via wires or cables, which provides stable transmission and is unaffected by external electromagnetic interference. Wireless communication can include Bluetooth, Wi-Fi, ZigBee, etc., which offer flexible installation and ease of movement. Other communication protocols can include specific communication protocols or interface standards (e.g., RS-232, RS-485, etc.).

[0052] Optionally, each detection device and controller can be powered on synchronously and synchronized. Within one power frequency cycle, the detection device can use the detected maximum electric field strength (AC line) or average electric field strength (DC line) as the first electric field strength and send it to the controller. For example, one power frequency cycle can be 0.2s.

[0053] S202, based on the position and attitude information of each detection device relative to the controller, convert each first electric field intensity into a corresponding second electric field intensity.

[0054] The electric field direction in the second electric field intensity is based on the controller coordinate system.

[0055] Optionally, the absolute position information and attitude information of each detection device and controller can be obtained. Then, the position information of each detection device relative to the controller can be determined based on the absolute position information of each detection device and the controller. Similarly, the attitude information of each detection device relative to the controller can be determined based on the attitude information of each detection device and the controller.

[0056] Optionally, the absolute position information of each detection device and controller can be determined by GPS or other positioning technologies, and the attitude information of each detection device and controller can be determined by an attitude sensor, which may include a gyroscope, magnetic compass, star sensor or infrared earth sensor, etc.

[0057] In one possible implementation, the first electric field strength, the position information and attitude information of each detection device relative to the controller can be input into a preset conversion model to determine the second electric field strength corresponding to each first electric field strength based on the output of the preset conversion model. The preset conversion model can be trained based on historical data.

[0058] In another possible implementation, a correction matrix can be constructed based on the position and attitude information of each detection device relative to the controller, and then each first electric field intensity can be converted into a corresponding second electric field intensity based on the correction matrix.

[0059] S203, generate electric shock warning information based on each second electric field strength and a preset electric field strength threshold.

[0060] Among them, the electric shock warning information is used to instruct operators to refrain from moving in the direction of the electric field in each of the second electric field intensities when the electric field intensity value does not meet the preset electric field intensity threshold.

[0061] Optionally, the preset electric field strength threshold can be determined by the operator according to the power regulations and preset in the controller. The preset electric field strength threshold can be adjusted according to the working environment to ensure work safety.

[0062] Optionally, if the electric field strength value of at least one second electric field strength is greater than or equal to a preset electric field strength threshold, or if the interpolation between the electric field strength value of at least one second electric field strength and the preset electric field strength threshold is less than or equal to a preset difference, then an electric shock warning message is generated.

[0063] Optionally, the electric shock warning information may include the second electric field strength and the location information of the controller.

[0064] The aforementioned electric shock warning method involves placing a controller inside a special-operation vehicle and multiple detection devices positioned around the vehicle. The method acquires the first electric field strength of each detection device, which describes the electric field strength value and direction at the device's location (the direction is determined based on the device's coordinate system). Then, based on the position and attitude information of each detection device relative to the controller, the first electric field strength is converted into a corresponding second electric field strength, where the direction is based on the controller's coordinate system. Finally, electric shock warning information is generated based on the second electric field strengths and a preset electric field strength threshold. This warning information instructs operators to refrain from moving in the direction of the electric field in any of the second electric field strengths when the electric field strength value does not meet the preset threshold. This method provides electric shock warnings by detecting electric field strength and offers operators possible movement directions when there is a risk of electric shock, thus avoiding safety hazards during operations and improving operational safety.

[0065] In one exemplary embodiment, such as Figure 3 As shown, optionally, based on the position and attitude information of each detection device relative to the controller, each first electric field intensity is converted into a corresponding second electric field intensity, including steps 301 to 302. Wherein:

[0066] S301, Generate a correction matrix for each detection device based on the position and attitude information of each detection device relative to the controller.

[0067] The correction matrix is ​​used to describe the change relationship from the detection device coordinate system to the controller coordinate system.

[0068] Optionally, in three-dimensional space, the correction matrix may include a rotation matrix and a translation vector, wherein the rotation matrix is ​​a 3×3 orthogonal matrix and the translation vector is a 3×1 vector.

[0069] Optionally, the included angle can be determined based on the attitude information of a detection device relative to the controller, and then the corresponding direction cosine can be determined. The direction cosine is the three direction cosines of the coordinate axes of the controller coordinate system relative to the coordinate system of the detection device. The calculated direction cosine is used to construct the rotation matrix; the translation vector is determined based on the position information of the detection device relative to the controller.

[0070] S302, determine each second electric field intensity based on the product of each correction matrix and the first electric field intensity.

[0071] Optional, such as Figure 4The diagram shows the positions of the detection device and the controller. Phases A, B, and C can represent the three phases of a power transmission line. In long-distance three-phase power transmission, the three phases (A, B, and C) are separated, and there are three common distributions: horizontal arrangement, triangular arrangement, and vertical arrangement. This application does not limit this arrangement and can be based on B1. Determine the second electric field strength, where, B1 represents the position information of the detection device relative to the controller, and B1 is the correction matrix. The first electric field strength is given.

[0072] The above method generates a correction matrix for each detection device based on the position and attitude information of each detection device relative to the controller. The second electric field intensity is determined by multiplying each correction matrix with the first electric field intensity. This yields the second electric field intensity based on the controller coordinate system. In this way, the electric field direction based on the second electric field intensity can output the direction in which the operator is prohibited from moving when there is a risk of electric shock, thereby improving work safety.

[0073] In one exemplary embodiment, such as Figure 5 As shown, optionally, the preset electric field strength threshold includes a warning electric field strength value and an air breakdown field strength value. Electric shock warning information is generated based on each second electric field strength and the preset electric field strength threshold, including the following steps 501 to 502. Wherein:

[0074] S501, obtain the warning electric field strength value and the air breakdown field strength value.

[0075] Optionally, the warning electric field strength value can be a safety threshold for the electric field strength set under specific conditions to ensure the safety of operators and the normal operation of equipment; the air breakdown field strength value can be a critical value, when the electric field strength in the air reaches this critical value, air molecules are ionized and a conductive path is formed. Determining the air breakdown field strength value can prevent power transmission lines and equipment from sending discharge phenomena.

[0076] Optionally, the warning electric field strength value and the air breakdown field strength value can be obtained by: obtaining the voltage level of each transmission line in the working environment, and determining the warning electric field strength value based on each voltage level and the corresponding safety distance; obtaining the air pressure in the working environment, and determining the air breakdown field strength value based on the air pressure.

[0077] Optionally, the correspondence between voltage levels and safe distances during operator operations can be determined according to power regulations, as shown in Table 1. The correspondence between voltage levels and safe distances during lifting operations in special operation vehicles can be shown in Table 2. The corresponding candidate warning electric field strength value can be determined based on the quotient of voltage level and safe distance. Then, the warning electric field strength value can be determined based on the distance between the special operation vehicle and the transmission line.

[0078] Table 1

[0079]

[0080] Table 2

[0081]

[0082] Optionally, when the air pressure in the working environment is standard atmospheric pressure (i.e., temperature is 20 degrees, pressure is 101325 Pa and absolute humidity is 11 g / m^3), the air breakdown field strength is 30 kV / cm. When the air pressure is greater than or equal to one-tenth of the standard atmospheric pressure, the air breakdown field strength E can be approximately estimated by the following formula: E / p = 30 V / km T0rr, where p is the air pressure and the unit is Torr, which is millimeters of mercury.

[0083] S502, if any electric field strength value among the second electric field strengths is greater than or equal to the warning electric field strength value, or if any electric field strength value among the second electric field strengths is greater than or equal to the air breakdown field strength value, then an electric shock warning message is generated based on the second electric field strength.

[0084] Optionally, if any electric field strength value in the second electric field strength is greater than or equal to the warning electric field strength value or the air breakdown field strength value, the electric field direction of the second electric field strength shall be regarded as the prohibited movement direction. If there are multiple electric field strength values ​​of the second electric field strength that are greater than or equal to the warning electric field strength value or the air breakdown field strength value, the electric field directions of the multiple second electric field strengths shall all be regarded as the prohibited movement directions.

[0085] The above method obtains the warning electric field strength value and the air breakdown field strength value. If any electric field strength value among the second electric field strengths is greater than or equal to the warning electric field strength value, or if any electric field strength value among the second electric field strengths is greater than or equal to the air breakdown field strength value, then electric shock warning information is generated based on the second electric field strength. This method can accurately generate electric shock warning information based on the second electric field strength, thus avoiding safety hazards during the operation process.

[0086] In one exemplary embodiment, optionally, the electric shock warning method further includes:

[0087] The electric shock warning information is output to the operator in a preset alarm mode, which includes communication alarm, sound and light alarm or voice alarm.

[0088] Optionally, after generating the electric shock warning information, the warning information can be output to the operator so that the operator can adjust their position according to the warning information to avoid electric shock.

[0089] Optionally, communication alarms may involve sending SMS messages, emails, or push notifications to the operator's pre-set terminal devices; audible and visual alarms may involve outputting electric shock warning information on the controller's screen and alerting the operator through changes in the light on the screen and a buzzer sound from the controller; voice alarms may involve the controller broadcasting electric shock warning information, or the controller sending the electric shock warning information to the operator's terminal so that the terminal can broadcast the electric shock warning information.

[0090] By outputting electric shock warning information to operators in a preset alarm manner, the above-mentioned method can promptly remind operators when there is a risk of electric shock, avoid safety hazards during operation, and improve work safety.

[0091] As an optional implementation method, such as Figure 6 As shown, the electric shock warning method provided in this application embodiment may include the following specific steps:

[0092] S601, obtain the first electric field strength of each detection device.

[0094] S602, generate a correction matrix for each detection device based on the position and attitude information of each detection device relative to the controller.

[0095] The correction matrix is ​​used to describe the transformation relationship from the detection device coordinate system to the controller coordinate system.

[0097] The electric field direction in the second electric field intensity is based on the controller coordinate system.

[0099] S605: Obtain the air pressure of the working environment and determine the air breakdown field strength value based on the air pressure.

[0100] S606, if any electric field strength value among the second electric field strengths is greater than or equal to the warning electric field strength value, or if any electric field strength value among the second electric field strengths is greater than or equal to the air breakdown field strength value, then an electric shock warning message is generated based on the second electric field strength.

[0101] Among them, the electric shock warning information is used to instruct operators to refrain from moving in the direction of the electric field in each of the second electric field intensities when the electric field intensity value does not meet the preset electric field intensity threshold.

[0102] S607 outputs electric shock warning information to the operator in a preset alarm mode.

[0103] Preset alarm methods include communication alarms, audible and visual alarms, or voice alarms.
