Description

Technical Field

[0001] The present invention belongs to the technical field of near-electricity operations, and in particular relates to an inductive anti-electric shock alarm positioning device and method for near-electricity operations. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] The tester is an important instrument for detecting whether the line or equipment is energized before the power grid is inspected. It plays a vital role in preventing the operation team from accidentally entering the energized interval and causing electric shock before taking safety measures. When inspecting or repairing the line, the operator uses the tester to test the power on both sides of the working line and equipment, and takes corresponding safety measures to ensure the safety of the operator.

[0004] However, the existing detection methods still pose certain safety risks when working near electricity:

[0005] (1) For fully insulated lines (equipment) that are shut down for inspection, effective direct electrical testing cannot be performed at the work site.

[0006] (2) Fully insulated lines (equipment) use live indicators to determine whether the equipment is live. The live indicator may fail to indicate the service life, which may lead to the risk of misjudgment.

[0007] (3) If workers go to the wrong interval when transferring to the work site, the supervisor may not be able to find and stop them in time, which may lead to electric shock accidents. Summary of the invention

[0008] In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides an inductive anti-electric shock alarm positioning device and method for near-electrical operations.

[0009] To achieve the above objectives, one or more embodiments of the present invention provide the following technical solutions:

[0010] The first aspect of the present invention provides an inductive anti-electric shock alarm positioning device for near-electric operation, comprising: a near-electric induction module, an alarm module, a positioning module and a main control module; the main control module is electrically connected to the near-electric induction module, the alarm module and the positioning module respectively;

[0011] The near-electric induction module is used to detect the magnetic field signal of the equipment to be repaired and convert it into a voltage signal and transmit it to the main control module; when the voltage value detected by the near-electric induction module exceeds the preset voltage value, the main control module controls the alarm module to send an alarm signal;

[0012] The working range of the operator is set through the main control module, and the positioning module is used to collect the position signal of the operator and transmit it to the main control module; when it is detected that the position of the operator exceeds the set working range, the main control module controls the alarm module to send an alarm signal.

[0013] A second aspect of the present invention provides an inductive anti-electric shock alarm positioning method for near-electricity operation, comprising:

[0014] Detect the magnetic field signal of the equipment to be repaired, and convert the detected magnetic field signal into a voltage signal;

[0015] Determine whether the detected voltage value exceeds the preset voltage value, and if so, issue an alarm signal;

[0016] The maintenance location of the equipment to be repaired is used as the central location to set the working scope of the operator;

[0017] Collect the position signal of the operator to determine whether the operator exceeds the set working range; if exceeded, an alarm signal is issued.

[0018] One or more of the above technical solutions have the following beneficial effects:

[0019] (1) The alarm positioning device provided by the present invention has voltage detection and alarm functions. It uses a near-electric sensor to detect in real time whether the equipment to be inspected is energized. When the real-time monitored voltage value exceeds the voltage alarm threshold, an audible and visual alarm signal is issued to prompt the operator, thereby ensuring the safety of the on-site operators. It solves the problem that the fully insulated equipment to be inspected cannot be effectively tested for electricity at the work site.

[0020] (2) The alarm positioning device provided by the present invention has a positioning function. By setting the working range of the operator, when it is detected that the position of the operator exceeds the set working range, an alarm signal is issued to prompt the operator; thus solving the problem that during the operation, the operator moves to the electrical interval by mistake and the supervisor cannot discover and stop it in time.

[0021] Advantages of additional aspects of the present invention will be given in part in the following description, and in part will become obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The accompanying drawings in the specification, which constitute a part of the present invention, are used to provide a further understanding of the present invention. The exemplary embodiments of the present invention and their descriptions are used to explain the present invention and do not constitute improper limitations on the present invention.

[0023] Figure 1 This is a schematic diagram of a first embodiment of an inductive anti-electric shock alarm positioning device for near-electricity operations.

[0024] Figure 2 This is a flow chart of a method for positioning an inductive anti-electric shock alarm for near-electrical operations according to a second embodiment. DETAILED DESCRIPTION

[0025] Embodiment 1

[0026] like Figure 1 As shown, this embodiment discloses an inductive anti-electric shock alarm positioning device for near-electric operation, comprising: a near-electric induction module, an alarm module, a positioning module and a main control module; the main control module is electrically connected to the near-electric induction module, the alarm module and the positioning module respectively;

[0027] The near-electric induction module is used to detect the magnetic field signal of the charged device and convert it into a voltage signal before transmitting it to the main control module; when the voltage value detected by the near-electric induction module exceeds the preset voltage value, the main control module controls the alarm module to send out an alarm signal;

[0028] The working range of the operator is set through the main control module, and the positioning module is used to collect the position signal of the operator and transmit it to the main control module; when the main control module detects that the position of the operator exceeds the set working range, the control alarm module sends an alarm signal.

[0029] When the maintenance line or equipment suddenly returns to power or the equipment to be inspected is energized, the near-inductive sensor will detect the magnetic field signal of the energized equipment, analyze and judge through the circuit acquisition module, amplify the electrical signal and convert it into a voltage signal for transmission to the main control module; the main control module compares the real-time detected voltage value with the voltage alarm threshold, and sends a control signal to the alarm module when the voltage alarm threshold is exceeded. The alarm module sends an alarm signal and immediately warns the operator to stop his dangerous behavior.

[0030] During the on-site survey, the positioning distance data of the work site is detected (it can be set according to the actual situation on site, such as the radius of the work site is not more than 5 meters). When the operator exceeds the 5-meter range, an alarm is issued immediately to remind him that he has exceeded the working range.

[0031] The working range of the operator is set through the main control module, including: taking the maintenance location of the equipment to be repaired as the center position, and setting the working range radius of the operator according to the center position.

[0032] Determine whether the operator exceeds the set working range, including: when the distance between the current position of the operator and the center position exceeds the set working range radius, the operator is deemed to have exceeded the set working range; otherwise, the operator is deemed to have not exceeded the set working range.

[0033] The main control module refreshes the location information at a fixed frequency. When the distance between the operator's position and the center position exceeds the set working radius, it is considered to have triggered the alarm threshold, and the main control module controls the alarm module to send out an alarm signal. When within the working range, the main control module monitors the operator's position information in real time through the positioning module, and will not trigger the alarm threshold or send out an alarm signal.

[0034] As a further technical solution, the alarm module is an audible and visual alarm device, including an LED lamp and a loudspeaker; the LED lamp is used to emit light of different colors, and the loudspeaker is used to emit different sound signals.

[0035] Specifically: when the voltage value detected by the proximity induction module exceeds the preset voltage value, the main control module sends a signal to control the sound and light alarm module to send out a sound and light alarm signal; for example, the LED light is controlled to flash red, and the speaker is controlled to send out a warning sound: "There is electricity, danger";

[0036] When the detected operator exceeds the set working range, the main control module sends a signal to control the sound and light alarm module to send out a sound and light alarm signal, for example, controlling the LED light to flash yellow light and controlling the speaker to send out a warning sound: "You have exceeded the working range."

[0037] As a further technical solution, the near-electric induction module is an electromagnetic induction sensor, which is a device that converts a magnetic signal into an electrical signal.

[0038] When the object being measured moves or changes, the physical quantity will affect the strength or direction of the magnetic field where the sensor is located, thereby changing the parameters of the electromagnetic induction circuit in the sensor and finally converting it into an electrical signal output. Electromagnetic induction sensors have the advantages of high sensitivity, fast response speed, and no need to contact the object being measured; by using electromagnetic induction sensors, it is possible to detect that the equipment to be repaired has electricity in the first place, thus ensuring the safety of the operators.

[0039] During power outage line inspection (or emergency repair), each member of the work team wears an induction alarm device, turns on the device before work, sets the voltage alarm threshold according to the working line voltage level, and self-checks whether the alarm device is working properly; if it is working normally, the LED alarm light flashes and the buzzer or speaker alarms; during the on-site survey before work, use a wristband for positioning.

[0040] As a further technical solution, a remote control terminal is also included, and the main control module and the remote control terminal exchange data through a communication module; the communication module includes a WiFi module, a Bluetooth module and / or a USB module.

[0041] The main control module can transmit the collected location information of the operating personnel to the remote control terminal, which can be a computer, mobile phone or other device; the management personnel can check the location information uploaded by the alarm device through the display page.

[0042] As a further technical solution, a power module is also included. The power module is electrically connected to the proximity sensing module, the alarm module, the positioning module, the communication module and the main control module, and the power module is used to provide power for each module.

[0043] As a further technical solution, it also includes a housing, a power module, a proximity induction module, an alarm module, a positioning module, a communication module and a main control module are all arranged inside the housing, and a device switch and a charging interface are provided on the housing;

[0044] By setting up the shell, the device has super waterproof and anti-interference performance; the alarm device can be charged through the charging interface.

[0045] As a further technical solution, by arranging structures such as silicone wristbands and elastic straps at both ends of the shell, the device can be worn on the wrist or arm of the operator as a wristband or armband, making it convenient for the operator to carry.

[0046] In the power grid line inspection or emergency repair work, the widespread use of inductive anti-electric shock alarm devices not only makes up for the shortcoming of not being able to conduct full-process electrical testing on fully insulated equipment in actual work, but also effectively prevents operators from mistakenly entering the live interval and arbitrarily expanding the scope of work to cause electric shock accidents. Through the widespread application of inductive anti-electric shock alarm devices, the safety of power grid operation and the safety management of personnel construction will be highly improved, which will bring immeasurable economic and social benefits to the company and society.

[0050] Determine whether the detected voltage value exceeds the preset voltage value, and if so, issue an alarm signal;

[0051] The maintenance location of the equipment to be repaired is used as the central location to set the working scope of the operator;

[0052] Collect the position signal of the operator to determine whether the operator exceeds the set working range; if exceeded, an alarm signal is issued;

[0053] Among them, judging whether the operator exceeds the set working scope includes:

[0054] When the distance between the operator's current position and the center position exceeds the set working range radius, the operator is deemed to be beyond the set working range; otherwise, the operator is deemed to have not exceeded the set working range.

[0055] Those skilled in the art should understand that the modules or steps of the present invention described above can be implemented by a general-purpose computer device, or alternatively, they can be implemented by a program code executable by a computing device, so that they can be stored in a storage device and executed by the computing device, or they can be made into individual integrated circuit modules, or multiple modules or steps therein can be made into a single integrated circuit module for implementation. The present invention is not limited to any specific combination of hardware and software.

[0056] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
