[0002] At present, the maintenance and testing work of primary power equipment in converter stations and substations is very numerous and complex. Due to the high voltage level in high-voltage converter stations and substations, the distance between primary equipment and the ground can usually reach 10 to 20 meters. When carrying out maintenance and testing work, staff need to frequently work on different aerial work platforms.

[0003] Due to the complex live conditions of primary equipment in converter stations and substations, some equipment is often out of power while others are live. If the workers working at heights are not familiar with the working environment, they cannot accurately judge the distance between their location and surrounding objects and the live conditions. Supervisors and commanders on the ground are also affected by the line of sight and cannot make judgments. If the workers mistakenly believe that the equipment is not live and accidentally touch live equipment, it will cause serious hazards such as personal injury and large-scale power outages. Or, during the operation, they cannot accurately judge the distance between themselves and the live equipment, and are injured by induced electricity, resulting in discomfort symptoms such as tingling and dizziness, causing major safety hazards.

[0036] The protection system for personnel working in electric fields provided in the embodiments of the present application can be applied to Figure 1 In the application environment shown. Among them, the operating personnel and the operating equipment are working in a high-voltage environment with live equipment. The electric field conditions in the working environment of the operating personnel are complex, and it is impossible to accurately identify the safe range of the operation. The protection system 102 for operating personnel in the live field is set in the personnel working area, or carried by the operating personnel and installed on the safety helmet or work clothes. The protection system 102 for operating personnel in the live field detects the working environment in which the operating personnel are located, determines whether the working environment in which the operating personnel are located is safe based on the detected environmental data, and issues an alarm message when it is determined that the working environment in which the operating personnel are located is unsafe, prompting the operating personnel that the current working environment is dangerous, so as to avoid the operating personnel from being too close to the live equipment and causing an operation safety accident. Specifically, the environmental detection module in the protection system 102 for operating personnel in the live field detects the environmental data of the working environment in which the operating personnel are located, and sends the environmental data to the processing module, and the processing module analyzes the acquired environmental data according to the preset alarm threshold. When the processing module compares the environmental data with the preset alarm threshold, the environmental data includes the electric field strength, the real-time distance between the live equipment and the operator, and the preset alarm threshold includes the preset electric field strength alarm threshold and the preset distance alarm threshold. When the electric field strength is greater than the preset electric field strength alarm threshold, and / or the real-time distance is less than the preset distance alarm threshold, the processing module sends an alarm instruction to the information prompt module. The information prompt module generates an alarm message when it obtains the alarm instruction. The alarm message is used to remind the operator that the current working environment is dangerous, so as to avoid operating safety accidents caused by the operator being too close to the live equipment, and to ensure the safety of the operator in the live field working environment.

[0037] In one embodiment, Figure 2 As shown, a protection system for personnel working in an electric field is provided, including: an environment detection module 202, a processing module 204 and an information prompt module 206, and the environment detection module 202 and the information prompt module 206 are both connected to the processing module 204. The environment detection module 202 is used to detect the environmental data of the working environment of the operator and send it to the processing module 204. The processing module 204 is used to compare the environmental data with the preset alarm threshold. The environmental data includes the electric field strength and the real-time distance between the live equipment and the operator. The preset alarm threshold includes a preset electric field strength alarm threshold and a preset distance alarm threshold. When the electric field strength is greater than the preset electric field strength alarm threshold, and / or the real-time distance is less than the preset distance alarm threshold, an alarm instruction is sent to the information prompt module 206, and the alarm instruction is used to control the information prompt module 206 to alarm. The preset alarm threshold is a user-defined threshold.

[0038] Among them, the environment detection module 202 is a collection module of sensors and related circuits and accessories for detecting the working environment of the operator. Environmental data includes but is not limited to the temperature, humidity, height, electric field strength of the working environment of the operator, and the distance from the surrounding live equipment. The preset alarm threshold is an alarm threshold corresponding to the environmental data and is set manually to ensure the safety of the operator. When the environmental data is greater than the threshold, it indicates that the working environment of the operator cannot guarantee the safety of the operator and needs to be evacuated as soon as possible.

[0039] Specifically, the environment detection module 202 detects the environment data of the working environment of the operator, and sends the environment data to the processing module 204. The processing module 204 processes and analyzes the environment data obtained by the environment detection module 202, and the processing module 204 compares the stored preset alarm threshold with the obtained environment data. When the electric field strength obtained by the processing module 204 is greater than the preset electric field strength alarm threshold, and / or the obtained real-time distance is less than the preset distance alarm threshold, the processing module 204 sends an alarm instruction to the information prompt module 206, and the alarm instruction is used to control the information prompt module 206 to alarm. The information prompt module 206 generates alarm information according to the alarm instruction, and the alarm information is used to remind the operator that the current working environment of the operator is dangerous.

[0040] Furthermore, the information prompt module 206 may provide corresponding information prompts according to the instructions sent by the processing module 204 , where the instructions include but are not limited to alarm instructions, and the information prompts include but are not limited to alarm information.

[0041] In this embodiment, the environment detection module detects the environment data of the working environment of the operator, and sends the environment data to the processing module. The processing module is used to send an alarm instruction to the information prompt module when the environment data is greater than the preset alarm threshold defined by the user, and control the information prompt module to alarm. Thus, the user can set different preset alarm thresholds according to different needs. The processing module controls whether the information prompt device alarms based on the size of the environment data and the preset alarm threshold. When there are adverse factors in the environment where the operator is located, the alarm can be issued in time to remind the operator to pay attention and ensure the safety of the operator when working in an electric field.

[0042] In one embodiment, Figure 3 As shown, the protection system for personnel working in electric fields further includes a monitoring module 302 connected to the processing module 204 . The monitoring module 302 obtains a preset alarm threshold according to a received user instruction and sends the preset alarm threshold to the processing module 204 .

[0043] The user instruction is an instruction input by an operator on the monitoring module 302 , and the user instruction can be processed in the monitoring module 302 to obtain a preset alarm threshold.

[0044] Specifically, the processing module 204 is also connected to the supervision module 302, and the location of the supervision module 302 is set by the supervisor. The supervisor can input user instructions on the supervision module 302, and the supervision module 302 processes the received user instructions to obtain a preset alarm threshold, and sends the preset alarm threshold to the processing module 204, and updates the original preset alarm threshold in the processing module 204. The processing module 204 compares the updated preset alarm threshold with the environmental data obtained from the environmental detection module 202.

[0045] Furthermore, the connection between the processing module 204 and the supervision module 302 may be a wired connection or a wireless connection. When the connection between the processing module 204 and the supervision module 302 is a wireless connection, the communication between the processing module 204 and the supervision module 302 may be a wireless network communication or a local area network communication. For example, it may be a 4G network communication.

[0046] Optionally, the supervision module 302 is set by the supervisor, and the location and method of setting are not unique. In combination with the difference in connection methods and operating equipment, the supervision module 302 can be set in the operating room of the operating equipment or carried by the supervisor. When there are multiple sets of the protection system 102 for workers in live field, the supervision module 302 in each set of the protection system 102 for workers in live field can also be set in a dedicated supervision room to facilitate unified management by supervisors.

[0047] In this embodiment, by setting up the supervision module 302 and remotely adjusting the preset alarm threshold in the processing module 204 through the supervision module 302, it is possible to cope with the changing live working environment, timely update the safety protection data required by the workers, and further ensure the safety of the workers when working in the live field.

[0048] In one embodiment, the processing module 204 is also used to send a remote alarm instruction to the supervision module 302 when the electric field strength is greater than a preset electric field strength alarm threshold and / or the real-time distance is less than a preset distance alarm threshold. The remote alarm instruction is used to control the supervision module 302 to alarm.

[0049] Specifically, the processing module 204 analyzes the environmental data obtained from the environmental detection module 202 according to the preset alarm threshold. When the electric field strength is greater than the preset electric field strength alarm threshold, and / or the real-time distance is less than the preset distance alarm threshold, the processing module 204 not only sends an alarm instruction to the information prompt module 206, but the information prompt module 206 also generates an alarm message when the alarm instruction is obtained, and the alarm message is used to remind the operator. The processing module 204 also sends a remote alarm instruction to the supervision module 302, and the supervision module 302 also generates an alarm message when the remote alarm instruction is obtained. The alarm message is used to remind the supervisor, reminding the operator that the current working environment is dangerous, so as to pay attention to the safety of the operator in a timely manner.

[0050] Furthermore, the processing module 204 will not only send a remote alarm command to the monitoring module 302, but also transmit the environmental data obtained from the environmental detection module 202 to the monitoring module 302. The monitoring module 302 obtains the environmental data of the working environment of the operator in real time and monitors the safety of the operator in real time.

[0051] In this embodiment, the processing module 204 sends remote alarm information and real-time environmental data to the monitoring module 302, so that the supervisor can timely understand the working environment of the operator through the monitoring module 302, so as to supervise the safe operation process of the operator.

[0052] In one embodiment, Figure 4 As shown, the supervision module 302 includes a signal transmission unit 402, a supervision processor 404 and a supervision interaction unit 406. The signal transmission unit 402 and the supervision interaction unit 406 are both connected to the supervision processor 404, and the signal transmission unit 402 is connected to the processing module 204. The signal transmission unit 402 is used to receive a remote alarm instruction from the processing module 204 and send it to the supervision processor 404. The supervision processor 404 is used to control the supervision interaction unit 406 to alarm according to the remote alarm instruction. The supervision interaction unit 406 is used to receive a user instruction and send it to the supervision processor 404. The supervision processor 404 is used to obtain a preset alarm threshold according to the user instruction and send it to the processing module 204 through the signal transmission unit 402.

[0053] Specifically, the supervision module 302 is used to receive the remote alarm instruction sent by the processing module 204, and is also used to obtain the preset alarm threshold according to the received user instruction, and send it to the processing module 204. When the supervision module 302 receives the remote alarm instruction sent by the processing module 204, the processing module 204 sends the remote alarm instruction to the supervision processor 404 through the signal transmission unit 402. After receiving the remote alarm instruction, the supervision processor 404 controls the supervision interaction unit 406 to generate alarm information according to the remote alarm instruction. The supervision module 302 can generate a preset alarm threshold according to the received user instruction and send it to the processing module 204. Specifically, the supervision interaction unit 406 obtains the user instruction input by the supervisor and transmits it to the supervision processor 404. The supervision processor 404 processes the user instruction to obtain the preset alarm threshold, and sends the preset alarm threshold to the processing module 204 through the signal transmission unit 402.

[0054] Furthermore, the supervision module 302 is used to receive the remote alarm instruction sent by the processing module 204, and is also used to receive the environmental data sent by the processing module and obtained from the environmental detection module 202. Specifically, the processing module 204 sends the environmental data to the supervision processor 404 through the signal transmission unit 402, and the supervision processor 404 receives the environmental data and transmits it to the supervision interaction unit 406.

[0055] Optionally, the supervisory interaction unit 406 includes an input device and a display device, both of which are connected to the supervisory processor 404, the input device is used for supervisors to input user instructions, and the display device is used to display remote alarm instructions and environmental data.

[0056] Exemplarily, the display device of the supervisory interaction unit 406 is used to form a visually visible picture, and may be a display screen, a projection device, or a virtual reality imaging device. The display screen may be a liquid crystal display screen or an electronic ink display screen, and the input device of the supervisory interaction unit 406 may be a touch layer covered on the display screen, or a key, trackball, or touchpad provided on the supervisory interaction unit 406, or an external keyboard, touchpad, or mouse, etc.

[0057] In this embodiment, the processing module 204 sends the environmental data and the remote alarm instruction to the supervision processor 404 through the signal transmission unit 402, and transmits it to the supervision interaction unit 406 for display; the supervision interaction unit 406 obtains the user instruction input by the supervisor, and transmits the user instruction to the supervision processor 404. After processing the user instruction, the supervision processor 404 obtains the preset alarm threshold, and transmits the preset alarm threshold to the processing module 204 through the signal transmission unit 402. Through the two-way communication between the processing module 204 and the supervision module 302, the real-time safety monitoring and adaptive adjustment of the operating personnel are realized.

[0058] When workers are working in an electric field, detecting the electric field strength of the working environment in which the workers are located is the most basic element to ensure the safety of the workers. Figure 5 As shown, the environment detection module 202 includes an electric field strength sensor 502, and the electric field strength sensor 502 is connected to the processing module 204. The preset alarm threshold includes a preset electric field strength alarm threshold. The electric field strength sensor 502 is used to detect the electric field strength of the working environment of the operator and send it to the processing module 204. The processing module 204 is used to send an alarm instruction to the information prompt module 206 when the electric field strength is greater than the preset electric field strength alarm threshold.

[0059] Specifically, the electric field strength sensor 502 detects the electric field strength of the working environment of the operator and sends it to the processing module 204. The processing module 204 processes and analyzes the electric field strength according to the preset electric field strength alarm threshold. When the electric field strength is greater than the preset electric field strength alarm threshold, the processing module 204 sends an alarm instruction to the information prompt module 206.

[0060] Furthermore, the connection between the electric field strength sensor 502 and the processing module 204 can be connected via an RS485 bus. When the electric field worker protection system also includes a monitoring module 302, the processing module 204 also sends the electric field strength to the monitoring module 302, and the monitoring module 302 is used to obtain a preset electric field strength alarm threshold according to a user instruction and send it to the processing module 204.

[0061] In this embodiment, by setting up the electric field strength sensor 502, the electric field strength of the working environment of the operator can be detected, and the electric field strength can be analyzed and processed by the protection system for operators in electric fields to achieve safety protection for operators in electric fields.

[0062] In one embodiment, Figure 6 As shown, the environment detection module 202 also includes a distance sensor 602, and the distance sensor 602 is connected to the processing module 204. The preset alarm threshold includes a preset distance alarm threshold. The distance sensor 602 is used to detect the real-time distance between the live equipment in the working environment of the operator and the operator, and send it to the processing module 204. The processing module 204 is used to send an alarm instruction to the information prompt module 206 when the real-time distance is less than the preset distance alarm threshold.

[0063] Specifically, the distance sensor 602 and the processing module 204 can be connected via an RS485 bus. The real-time distance between the live equipment in the working environment of the operator and the operator is detected and sent to the processing module 204. The processing module 204 processes and analyzes the real-time distance according to the preset distance alarm threshold. When the real-time distance is less than the preset distance alarm threshold, the processing module 204 sends an alarm instruction to the information prompt module 206.

[0064] Furthermore, when the protection system for personnel working in electric fields also includes a monitoring module 302 , the processing module 204 also sends the real-time distance to the monitoring module 302 , and the monitoring module 302 is used to obtain a preset distance alarm threshold according to user instructions and send it to the processing module 204 .

[0065] In this embodiment, by setting a distance sensor 602 on the basis of setting the electric field strength sensor 502, the electric field strength of the working environment of the operator and the real-time distance between the live equipment and the operator can be detected. By analyzing and processing the electric field strength and real-time distance by the protection system for operators in live fields, comprehensive safety protection for operators in live fields can be achieved.

[0066] The choice of the distance sensor is not exclusive. In one embodiment, the distance sensor includes a laser distance sensor and / or a millimeter wave distance sensor.

[0067] Among them, laser ranging sensors are sensors that use the high directivity, high monochromaticity and high brightness of lasers to achieve non-contact long-distance measurement. Millimeter wave ranging sensors are sensors that use wavelengths in the millimeter range to send signals, use non-contact technology to detect objects, and provide information on the distance, speed, and angle of objects.

[0068] Specifically, when the distance sensor is a laser ranging sensor, the laser ranging sensor can accurately measure the real-time distance between the live equipment in the working environment of the operator and the operator, and send the real-time distance to the processing module 204, and the processing module 204 processes and analyzes the real-time distance according to the preset distance alarm threshold. When the distance sensor is a millimeter wave ranging sensor, the millimeter wave ranging sensor can measure the real-time distance between the live equipment in the working environment of the operator and the operator, and can also measure the relative movement between the operator and the live equipment, and send the real-time distance and relative movement to the processing module 204, and the processing module 204 processes and analyzes the real-time distance according to the preset distance alarm threshold. When the protection system 102 for workers in live field also includes a supervision module 302, the processing module 204 also sends the real-time distance and relative movement to the supervision module 302.

[0069] Furthermore, the distance sensor is a laser distance sensor and a millimeter wave distance sensor, which are combined to measure the real-time distance and relative movement between the live equipment in the working environment of the operator and the operator.

[0070] Optionally, the number of distance sensors is not limited and can be any number of one or more.

[0071] In this embodiment, the distance sensor can be a laser distance sensor, which has a wide measurement range and high accuracy, and can obtain accurate real-time distances from live equipment. The distance sensor can also be a millimeter wave distance sensor, which can measure the relative motion between the operator and the live equipment while measuring the distance. The processing module can also predict the distance between the operator and the live equipment by analyzing the relative motion. By using different distance sensors, the real-time distance between the live equipment in the working environment of the operator and the operator can be accurately measured, fully ensuring the safety of the operator.

[0072] In one embodiment, Figure 7 As shown, the protection system 102 for workers working in electric fields also includes a first power module 702 and a second power module 704 . The first power module 702 is connected to the distance sensor 602 , the second power module 704 is connected to the electric field strength sensor 502 , and the processing module 204 is connected to the first power module 702 or the second power module 704 .

[0073] Specifically, the electric field strength sensor 502 and the distance sensor 602 are powered respectively, the second power supply module 704 is connected to the electric field strength sensor 502, and is used to power the electric field strength sensor 502; the first power supply module 702 is connected to the distance sensor 602, and is used to power the distance sensor 602. The processing module 204 can be connected to the first power supply module 702 and powered by the first power supply module 702; it can also be connected to the second power supply module 704 and powered by the second power supply module 704.

[0074] Furthermore, because the installation conditions for the distance sensor 602 may be more demanding, in order to more accurately measure the real-time distance, it is necessary to maintain the installation flexibility of the distance sensor 602. Therefore, it can be configured that the processing module 204 and the electric field strength sensor 502 are powered by the second power module 704, and the distance sensor 602 is powered by the first power module 702 alone, so as to ensure that the distance sensor 602 can work continuously and stably.

[0075] The battery selection of the first power module 702 and the second power module 704 is not limited. For example, the first power module 702 may be a 12V lithium battery, and the second power module 704 may be a 3V lithium battery.

[0076] In this embodiment, by powering the electric field strength sensor 502 and the distance sensor 602 separately, the safety protection is not in place when one sensor fails or is low on power, and the safety hazard of inadequate detection caused by low power is solved.

[0077] In one embodiment, Figure 8 As shown, the protection system 102 for personnel working in electric fields further includes a cloud server 802 . The cloud server 802 is connected to the processing module 204 . The processing module 204 is also used to send environmental data to the cloud server 802 .

[0078] Specifically, the processing module 204 sends the environmental data acquired by the environmental detection module 202 to the cloud server 802. The cloud server 802 stores the environmental data so that when the terminal device queries the environmental data, the corresponding environmental data can be called at any time and sent to the terminal device.

[0079] Optionally, the connection between the cloud server 802 and the processing module 204 can be a 4G communication connection, and the terminal device can directly query the cloud server 802 when querying the environmental data, or can connect to the cloud server 802 through a small program or APP (third-party application) to query. The terminal device includes but is not limited to an Internet of Things device, a computer device, and a smart phone device.

[0080] In this embodiment, the environmental data obtained by the environmental detection module 202 is sent to the cloud server 802 through the processing module 204, so that the environmental data can be viewed remotely, which is beneficial for other personnel to view the environmental data of the working environment of the operators, and the historical environmental data can be viewed and analyzed, further ensuring the safety of the operators working in the electric field.

[0081] According to the different structures of the information prompt module 206, the information prompting method is not unique, and the prompting method includes but is not limited to one or more of sound, light, graphics, and text. In one embodiment, the information prompt module 206 includes at least one of an audible and visual alarm and a vibration alarm.

[0082] Specifically, the information prompt module 206 is used to receive the alarm instruction sent by the processing module 204 when the environmental data is greater than the preset alarm threshold, and the alarm instruction is used to control the information prompt module 206 to alarm. The alarm method is not unique, and it can serve as an information prompt. When the information prompt module 206 adopts an audible and visual alarm, the processing module 204 sends an alarm instruction to the audible and visual alarm, and the audible and visual alarm uses at least one of an indicator light and a loudspeaker to provide information prompts, and issues an alarm to make the operator aware of the danger of the working environment in which he is located, avoid electric shock and ensure the safety of the operation. When the information prompt module 206 adopts a vibration alarm, the processing module 204 sends an alarm instruction to the vibration alarm, and the vibration alarm issues an alarm through its own vibration, so that the operator is aware of the danger of the working environment in which he is located, avoid electric shock and ensure the safety of the operation. The information prompt module 206 can also use an audible and visual alarm and a vibration alarm at the same time, and issue an alarm through an indicator light, a loudspeaker and a vibration touch.

[0083] Furthermore, the information prompt module 206 also includes a display device, which is connected to the processing module 204 and is used to form a visually visible picture and display the environmental data sent to the display device by the processing unit 204. Exemplarily, the display device can be a display screen, a projection device, or a virtual reality imaging device. The display screen can be a liquid crystal display screen or an electronic ink display screen.

[0084] Furthermore, the display device included in the information prompt module 206 is also used to generate an alarm signal according to the alarm instruction, including but not limited to representing the alarm information through patterns, texts, colors, symbols and other indicators through the display screen in the display device.

[0085] In this embodiment, by setting up a variety of information prompt modules 206, using different alarms or display devices to receive the alarm instructions sent by the processing module 204, and the alarm instructions control the alarm or display device to alarm, it is possible to inform the operating personnel of the dangerous working environment through various and comprehensive alarm prompts, thereby ensuring the operating safety of the operating personnel.

[0086] In order to better understand the above scheme, combined with Figure 1 The application scenario shown is explained in detail below in conjunction with a specific embodiment.

[0087] The structure of the protection system for personnel working in electric fields is as follows: Fig. 9As shown, the protection system for personnel working with electric fields includes an environment detection module, a processing module, an information prompt module, a supervision module, a first power module, a second power module and a cloud server. Among them, the environment detection module includes an electric field strength sensor and a distance sensor, wherein the electric field strength sensor is a power frequency electric field sensor, and the distance sensor is a laser ranging sensor. The information prompt module is an audible and visual alarm, the first power module is a 12V lithium battery, and the second power module is a 3V lithium battery. The laser ranging sensor and the power frequency electric field sensor are connected to the processing module via the RS485 bus respectively. In this embodiment, the processing module is a host computer, and the host computer includes a 4G communication interface, a processor, an RS485 interface and a power input port. The 4G communication interface is connected to the cloud server and the supervision system, and the RS485 interface is connected to the laser ranging sensor and the power frequency electric field sensor. The power access port is used to connect the power supply. The host computer is provided with an audible and visual alarm as an information prompt module, wherein the laser ranging sensor and the host computer are jointly powered by a 12V lithium battery, and the power frequency electric field sensor is powered by a 3V lithium battery alone. The host computer is also connected to the monitoring module and the cloud server through the 4G communication interface. The cloud server is used to interact with the applets or apps of other terminal devices to receive alarm information and view environmental data.

[0088] During use, the operator carries the electric field operator protection system with him when performing high-altitude electric field operations, and installs the laser distance sensor and the power frequency electric field sensor on the safety helmet or work clothes. The electric field operator protection system measures the surrounding environment through the laser distance sensor and the power frequency electric field sensor, obtains the electric field strength and real-time distance, and sends the electric field strength and real-time distance to the host computer through the RS485 bus. The host computer compares and analyzes the electric field strength and real-time distance according to the preset alarm threshold, and uploads the electric field strength and real-time distance to the supervision module and cloud server through 4G communication, so that supervisors and other personnel can check the electric field strength of the working environment of the operator and the real-time distance from the energized equipment in time.

[0089] When the host computer compares and analyzes the preset alarm threshold, electric field strength and real-time distance, after collecting the electric field strength (V / m) sent by the power frequency electric field sensor, the host computer compares it with the preset electric field strength alarm threshold. If the preset electric field strength alarm threshold is exceeded, it means that the equipment in front is energized or the distance to the energized equipment is too close, then an alarm command is immediately sent to the sound and light alarm, triggering the sound and light alarm to generate an alarm signal to alert the operator. The host computer also sends a remote alarm command to the supervision module to inform the supervisor in time. In addition, the host computer will also transmit the electric field strength data and alarm command to the cloud server for recording, so that other personnel can view it later. The operator stops the operation after receiving the alarm information. If the electric field strength does not exceed the preset electric field strength alarm threshold, the real-time distance (m) value sent by the collected laser ranging sensor is compared with the preset distance alarm threshold. If the measured real-time distance is less than the preset distance alarm threshold, an alarm command is sent to the sound and light alarm, triggering the sound and light alarm to generate an alarm signal to alert the operator. The host computer also sends a remote alarm command to the supervision module to inform the supervisor in time. The host computer will also transmit the real-time distance data and alarm command to the cloud server for recording so that other personnel can view it later. The operator stops working after receiving the alarm information. If the electric field strength of the working environment where the operator is located and the real-time distance between the operator and the live equipment meet the corresponding preset alarm thresholds, the operator can work normally. At the same time, the power frequency electric field sensor and the laser ranging sensor use 120 milliseconds (ms) as a test cycle to continuously measure the surrounding working environment of the operator, and transmit the electric field strength and real-time distance data to the host computer in real time. The host computer uploads it to the supervision module and the cloud server through 4G network communication. The supervisor can monitor the working environment of the operator in real time through the supervision module, and the supervisor can update the preset alarm threshold in the host computer through the supervision module to deal with the changing working environment and ensure the safety of the operator. The cloud server stores the electric field strength and real-time distance data, which is convenient for mobile devices to download real-time data from the cloud server and analyze and query the operation activity history of the operator.

[0090] In one embodiment, the supervision module is set in a mobile phone. The supervisor updates the preset alarm threshold in the host computer through the supervision module in the mobile phone and performs protection for personnel working in the electric field. The process is as follows: Fig.10 shown.

[0091] The supervisor selects the preset alarm threshold according to the safe working distance and the electric field strength threshold of the working environment specified in the power work safety regulations. The supervisor sets the preset alarm threshold through the mobile phone, which includes the preset electric field strength alarm threshold and the preset distance alarm threshold. The mobile phone communicates with the host computer and transmits the preset alarm threshold to the host computer so that the host computer updates the preset alarm threshold. The host computer obtains the electric field strength and real-time distance detected by the environment detection module. First, the electric field strength is compared with the preset electric field strength alarm threshold. If the electric field strength is within the preset electric field strength alarm threshold, the real-time distance is compared with the preset distance alarm threshold. If the electric field strength is not within the preset electric field strength alarm threshold, it is judged that the working environment of the operator is dangerous, and the host computer sends an alarm command to control the sound and light alarm to alarm, and the operator should immediately stop working and leave the current working environment. The host computer will also send remote alarm commands to the mobile phone to facilitate supervisors to monitor the working environment of the operator. If the electric field strength is within the preset electric field strength alarm threshold, and the real-time distance is within the preset distance alarm threshold, the working environment of the operator is judged to be safe, and the host computer uploads the electric field strength and real-time distance to the mobile phone, so that the supervisor can monitor in real time through the mobile phone. If the electric field strength is within the preset electric field strength alarm threshold, but the real-time distance is not within the preset distance alarm threshold, the working environment of the operator is judged to be dangerous, and the host computer sends an alarm command to control the sound and light alarm to alarm, and the operator should immediately stop working and leave the current working environment. The host computer will also send remote alarm commands to the mobile phone to facilitate supervisors to monitor the working environment of the operator.

[0092] In this embodiment, workers carry a protection system for workers in electric fields with them when performing high-altitude operations in electric fields. The protection system for workers in electric fields accurately determines whether the working environment is less than the safe working distance required by the regulations, identifies whether the surrounding equipment is energized, and transmits relevant information to the mobile phones of ground supervisors, making it convenient for supervisors to monitor remotely and effectively reducing the risks of high-altitude operations in electric fields.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
