[0025] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0026] Embodiment 1

[0027] Figure 1 A schematic diagram of a power grid operation safety detection device provided in the first embodiment of the present invention is shown in FIG. Figure 1 As shown, the power grid operation safety detection device 100 includes:

[0028] The safety belt 1 and the control circuit 2, non-contact inductive electricity measuring device 3, inductive electricity strength distinguishing device 4 and sound and light alarm device 5 fixedly connected to the safety belt 1; the non-contact inductive electricity measuring device 3 is electrically connected to the inductive electricity strength distinguishing device 4; the non-contact inductive electricity measuring device 3, inductive electricity strength distinguishing device 4 and sound and light alarm device 5 are all electrically connected to the control circuit 2; the control circuit 2 can control the non-contact inductive electricity measuring device 3, inductive electricity strength distinguishing device 4 and sound and light alarm device 5 to start and stop running, as well as the specific running mode during running. It should be noted that, in Figure 1 In the figure, the connection between two modules or devices (circuits) indicates that there is an electrical connection between the two, and the safety belt 1 is physically connected to the above modules or devices. Among them, the safety belt 1 is the equipment worn by the operator when working at high altitudes; if the above modules or devices are installed on the safety belt 2, the operator can detect the safety situation of the environment in which the safety personnel are located in real time when working or moving.

[0029] The non-contact inductive electricity measuring device is used to detect the induced electricity intensity of the charged body at the operator's location; the induced electricity strength discrimination device is used to output a control signal to the control circuit according to the induced electricity intensity; the control circuit is used to control the operation of the sound and light alarm device according to the control signal.

[0030] Specifically, when the induced electricity intensity is greater than a preset induced electricity intensity threshold, the control signal sent by the induced electricity intensity determination device may include an alarm signal, and the control circuit controls the sound and light alarm device to alarm when receiving the alarm signal.

[0031] Optionally, the non-contact inductive electrical measuring device includes an inductive electrical Hall sensor and a data processing circuit; the data processing circuit is electrically connected to the inductive electrical Hall sensor and the inductive electrical strength determination device; the inductive electrical Hall sensor is used to collect the inductive electrical signal and transmit it to the data processing circuit; the data processing circuit is used to perform data processing on the inductive electrical signal to obtain the inductive electrical strength.

[0032] The induced electric signal can be a voltage signal, and the induced electric intensity can be a voltage intensity. The induced electric signal and induced electric intensity detected here are both the induced electric signal and induced electric intensity of the charged body near the safety belt. When the induced electric Hall sensor (on the safety belt) slowly approaches the high-voltage charged body, when the charged particles (electrons or holes) are confined in the solid material, this deflection leads to the accumulation of positive and negative charges in the direction perpendicular to the current and magnetic field, thereby forming an additional transverse electric field. Under the action of the Lorentz force, the electron flow of I deviates to one side when passing through the Hall semiconductor, causing the sheet to generate a potential difference in the CD direction, which is the so-called Hall voltage. The Hall voltage changes with the change of the magnetic field strength. The stronger the magnetic field, the higher the voltage, and the weaker the magnetic field, the lower the voltage. On the contrary, when the Hall sensor is close to the strong magnetic field of the high-voltage charged body, the stronger the magnetic field, the higher the voltage.

[0033] In an optional embodiment, the power grid operation safety detection device further includes a patch sensor, the patch sensor is electrically connected to the data processing circuit, and the data processing circuit is also connected to the control circuit;

[0034] The patch sensor is used to detect a wearing signal of the safety belt when the safety belt is worn by the operator;

[0035] The data processing circuit is also used to perform data processing on the wearing signal to obtain wearing condition information and send it to the control circuit;

[0036] The control circuit is also used to control the operation of the sound and light alarm device according to the wearing condition information.

[0037] Specifically, the wearing signal may include pressure and temperature. When the safety belt is worn by the operator, the patch sensor can detect the wearing pressure and the temperature from the operator's body. Therefore, the wearing condition of the safety belt by the operator can be determined by detecting the pressure and temperature. When the safety belt is worn improperly (does not meet the wearing standards) or is not worn, the sound and light alarm device can be used to remind the operator to wear the safety belt according to the wearing standards.

[0038] Figure 2 Schematic diagram of the structure of a safety belt and a drainage device, such as Figure 2 As shown, the non-contact inductive electrical measuring device 3 and the patch sensor 6 fixing device are directly installed on the safety belt 1, so that when the operator gradually approaches the high-voltage source, the warning can be issued faster than using the safety belt 1 or storing the anti-high-voltage electric shock voice prompt alarm body close to the body, thereby improving the safety of use. It does not need to be held in the hand or stored close to the body by the user, which is convenient for construction personnel to operate.

[0039] In an optional embodiment, the induced electricity strength discrimination device includes a single chip microcomputer and a data discrimination circuit, the single chip microcomputer is electrically connected to the non-contact inductive electricity measuring device and the data discrimination circuit, and the data discrimination circuit is also electrically connected to the control circuit;

[0040] The non-contact inductive electrical measuring device is used to detect the induced electrical intensity and send the induced electrical intensity to the data discrimination circuit through the single-chip microcomputer; the data discrimination circuit is used to send a control signal to the control circuit when the induced electrical intensity is greater than a preset induced electrical intensity threshold.

[0041] In an optional embodiment, a microcontroller is also included, such as Figure 3 As shown, Figure 3 It is a partial structural diagram of a microcontroller, wherein the microcontroller includes an ultrasonic ranging module 21, a wireless receiving module 22, a main control module 23 and a voice broadcasting module 24.

[0042] The safety belt is also connected to a telescopic support rod, the length of which is proportional to the distance between the operator and the charged object, and the length of which is controlled by the main control module;

[0043] The ultrasonic distance measuring module is used to measure the distance signal from the charged object to the operator and send it to the main control module through the wireless receiving module; the main control module is used to process the distance signal to obtain the actual distance between the detection operator and the charged object and obtain the safe distance of the charged object; based on the safe distance and the actual distance, the length of the telescopic support rod is adjusted and the voice broadcast module is controlled to operate. Combined with the ultrasonic distance measuring module, the safe distance from the charged object can be accurately measured, and combined with the voice broadcast module, the safe distance from the charged object can be warned in advance.

[0044] The telescopic support rod is the support rod of the safety belt. The telescopic support rod is retractable, so the height of the safety belt can be adjusted by adjusting the length of the support rod, that is, the distance between the operator and the charged object can be adjusted. When the actual distance between the operator and the charged object is less than the safe distance or approaches the safe distance, the main control module can control the voice broadcast module to issue a voice warning to remind the operator to adjust the current position and increase vigilance, and automatically control the length of the telescopic support rod to keep the operator away from the charged object.

[0045] In an optional example, the operator is working at high altitude, and the high-voltage live object is located above the operator. When the telescopic support rod is extended, the operator is away from the live object. When the telescopic support rod is shortened, the operator is close to the live object. When the actual distance between the operator and the live object is less than the safe distance or approaches the safe distance, the main control module controls the extension of the telescopic support rod to keep the operator away from the live object, avoid the operator getting close to the high-voltage live object and get injured, and ensure the safety of the operator. Specifically, when the power supply of the power module is turned on, the induction detection module detects that the induced voltage exceeds the preset value, or the measured value of the ultrasonic ranging module during the measurement is less than the preset value (7m), indicating that the preset safety distance has been exceeded, and the height of the telescopic support rod needs to be adjusted to meet the safety operation requirements. The main control module will send a control signal to make the voice broadcast module send a voice alarm, and at the same time, the illegal operation information of the on-site illegal operator monitored will be transmitted to the safe operation monitoring platform and the guardian's smartphone terminal in real time.

[0046] In an optional embodiment, if Figure 3 As shown, the microcontroller also includes an environment compensation module 25 electrically connected to the main control module 21. The environment compensation module is used to obtain environmental information in the working environment, determine a compensation signal of the distance signal of the ultrasonic ranging module based on the environmental information, and send the compensation signal to the main control module; the main control module is also used to compensate the distance signal according to the compensation signal.

[0047] The ultrasonic ranging range is around the operating radius centered on the operator. Due to the influence of environmental factors such as ambient temperature and humidity, an environmental compensation module is needed to compensate and dynamically adjust the signal to adapt to the influence of errors caused by environmental factors, so as to achieve ranging accuracy. The programmable module can adjust the ranging range according to the on-site conditions to adapt to the use conditions of different voltage levels.

[0048] In an optional embodiment, if Figure 3 As shown, the microcontroller also includes a drainage device 26 connected to the main control module 23. Figure 2 As shown, the drainage device 26 includes a drainage detection module 261 and a drainage protection module 262, and the drainage protection module 262 includes a drainage wire.

[0049] One end of the drainage wire is connected to the safety belt, and the other end is grounded. The resistance of the drainage wire is less than the preset human body resistance; the drainage detection module is connected in series to the drainage protection module; the drainage detection module is also connected to the main control module; the drainage detection module is used to detect the leakage data passing through the drainage protection module and send it to the main control module; the main control module is used to control the operation of the voice broadcast module when receiving the leakage data.

[0050] Once the operator touches a charged object, the patch sensor on the safety belt will detect the current flowing through the human body, and if the voltage exceeds the safety value, the drainage device will automatically start the protection function. Since the operator touches the charged object, current will flow through the human body. The wire resistance of the drainage device is smaller than that of the human body, and the resistance to current is small. The current will be diverted from the drainage device first and drained to the ground through the rear tail rope wire of the safety belt. At the same time, the drainage device of the safety belt is connected in series with a current detection device. Once current flows, a current signal will be detected and the detected current signal will be sent to the safety supervision operation monitoring platform in time. At the same time, the safety belt will also activate the alarm device to remind the operator that he has touched the charged object and to evacuate the live operation area in time to prevent the operator from being electrocuted.

[0051] On the one hand, even if the power grid operator accidentally touches the charged object, the drainage device can be quickly activated to quickly lead the current into the ground to prevent the risk of electric shock, effectively improving the safety of on-site power grid operations and ensuring the safety of on-site operators. On the other hand, usually when the operator touches the charged object without wearing insulating gloves, the drainage detection module will detect leakage data. At this time, the main control module on the safety belt will control the voice broadcast module to issue an early warning message, and at the same time, the information of the operator's illegal operation will be promptly fed back to the safe operation monitoring platform. After receiving the information fed back by the intelligent main control module, the safe operation monitoring platform will promptly remind the operator to wear insulating gloves when working.

[0052] In addition, wearable sensing devices can be embedded in insulating gloves. Only when the workers put on the insulating gloves and their hands sense the wearable sensing devices, the information of putting on the gloves is transmitted to the main control module or control circuit in the smart safety belt. The main control module or control circuit then transmits the workers' standardized operations to the safe operation monitoring platform. At the same time, the safety belt can also be embedded with a camera to collect images of visual operations, and further identify whether the workers are wearing insulating gloves. This can double-judge whether the workers are working in a standardized manner to improve the safety of operations.

[0053] Optionally, voltage and current detection sensors can be set inside the drainage device to detect the voltage levels and currents of different leakages and adjust the cross-sectional area of ​​the drainage device. The larger the leakage current, the larger the cross-sectional area of ​​the drainage device will be adjusted, thereby reducing the maximum resistance of the drainage device and reducing the resistance to drainage, thereby improving the efficiency of leakage drainage.

[0054] In an optional embodiment, the main control module is also connected to a safe operation monitoring platform, and the main control module is also used to upload the leakage data to the safe operation monitoring platform when it is received. The safe operation monitoring platform can collect and analyze the leakage data to optimize the power grid operation safety detection device and monitor the safety of the operators in real time.

[0055] In an optional embodiment, it also includes a host fixedly connected to the safety belt, the host is equipped with a main power switch and a power module, and the control circuit, the non-contact inductive electricity measuring device, the inductive electricity strength judgment device and the sound and light alarm device are all connected to the power module in the host. The power supply of the device connected to the host can be turned on or off by the main power switch of the host. Optionally, the power grid operation safety detection device also includes an energy storage module connected to the power module, the energy storage module is connected to the solar photovoltaic panel, and the solar energy is converted into electrical energy through the solar photovoltaic panel and stored in the energy storage module, and the energy storage module supplies power to the power module.

[0056] In an optional embodiment, the sound and light alarm device includes a sound and light alarm circuit, an LED lamp and a voice module, the LED lamp is installed on the outer surface of the host, and the sound and light alarm circuit and the voice module are both installed in the inner cavity of the host.

[0057] In another optional embodiment, the non-contact induction electricity measuring device further includes a display screen, so that the operator can visually obtain the current induction electricity information and know the voltage intensity at the current location.

[0058] The inductive electricity detection device for the power grid operation safety belt of the present invention has the following advantages: the alarm device of the present invention is worn on the safety belt by the maintenance personnel and carried with them. When the maintenance personnel approach the electrical equipment, the non-contact inductive electricity measuring device begins to detect the inductive electricity carried by the shell of the electrical equipment, and the inductive electricity strength discrimination device analyzes and discriminates the measured inductive electricity value. If the value is greater than the preset intensity value, the sound and light alarm device will issue a corresponding alarm to remind the maintenance personnel, thereby achieving the purpose of avoiding personal injury. The present invention has a simple structure and is safe and reliable to use, avoiding the risk of electric shock for power grid operators. The height detection device has an extremely small height measurement error. The non-contact power grid operation safety belt is compact and light, and is easy to disassemble and carry.

[0059] Optionally, the power grid operation safety detection device also includes a watch, which is worn on the operator's wrist and can detect the operator's heart rate, blood pressure and other human body data to prevent the operator from having a high heart rate or high blood pressure due to climbing.
