Description

Technical Field

[0001] The invention relates to the technical field of electrical safety against electric shock, and in particular to a wearable device for contactless measurement of step voltage. Background Art

[0002] Step voltage electric shock is an electric shock accident that occurs when a person stands within 8 meters outdoors and within 4 meters indoors from the landing point of a high-voltage wire or a live conductor. When a person stands on a ground short-circuit loop with a distance of 0.8 meters between his feet, the voltage that the person is subjected to is called step voltage. When a person is subjected to step voltage, the current flows along the person's lower body, from the feet through the legs and crotch to the feet and the ground to form a path.

[0003] During electrical operations, when the step voltage reaches 40-50V, there will be a risk of electric shock. In particular, the step voltage can cause people to fall and increase the electric shock voltage on the human body, and may even cause death by electric shock. People cannot detect whether they have entered the step voltage danger zone, and people often mistakenly enter the zone, resulting in electric shock accidents. Summary of the invention

DETAILED DESCRIPTION

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Example 1, reference Figure 1 to Figure 2 , which is the first embodiment of the present invention, and provides a wearable device for contactless step voltage measurement, comprising an external component 100, including a sole 101, a connection pad 101a provided at one end of the sole 101, and a heel 101b provided at one end of the sole 101; and,

[0028] The connection assembly 200 includes a circuit board 201 disposed above the sole 101 and a computing chip 201a disposed above the circuit board 201; and,

[0029] The sensing component 300 includes a sensing pad 301 disposed at one end of the connecting pad 101a; and

[0030] The driving assembly 400 includes a power management board 401 disposed above the heel 101b and a connection chip 401a disposed above the power management board 401; and,

[0031] The warning component 500 includes a warning indicator light 501a disposed above the connection pad 101a.

[0032] The external component 100 further includes a charging port 102 disposed at one end of the heel 101b and a toe cap 103 disposed above the connection pad 101a.

[0033] The charging interface 102 is electrically connected to the power management board 401 .

[0034] The connection pad 101a provided at the front of the sole 101 and the flexible multi-turn high-sensitivity induction coil 301a are used for intelligent sensing and measuring the electromagnetic field strength of the ground.

[0035] A high-sensitivity induction coil 301a is provided through the connection pad 101a for intelligently sensing and measuring the electromagnetic field strength of the ground.

[0036] Usage process: Set a high-sensitivity induction coil 301a through the connection pad 101a. When the wearable device detects that the electromagnetic intensity of the ground exceeds a threshold, the induction coil 301a will electromagnetically transmit the signal to the warning component 500. At this time, the alarm indicator 501a outside the warning component 500 will receive the signal, and the alarm indicator 501a will emit a red light to alarm, thereby reminding electrical personnel to stay away from this area to prevent them from electric shock accidents.

[0037] Example 2, reference Figure 1 to Figure 2 , which is the second embodiment of the present invention, provides a wearable device for contactless step voltage measurement, which includes a connection component 200 and also includes a first connection cable 202 arranged at one end of a circuit board 201 and a second connection cable 203 arranged at one end of the circuit board 201.

[0038] The sensing component 300 further includes a sensing coil 301 a disposed above the sensing pad 301 . The sensing coil 301 a is connected to the second connecting cable 203 .

[0039] The induction coil 301a is in a ring shape.

[0040] The driving assembly 400 further includes a connecting battery 401b disposed above the power management board 401. A connecting wire is disposed at one end of the power management board 401, a driving member 402 is disposed at one end of the connecting wire, and a sensing sensor 403 is disposed at the other end of the connecting wire. The connecting wire is electrically connected to the circuit board 201.

[0041] The circuit board 201 at one end of the sole 101 is used to control the operation of each module circuit, control the alarm and detection circuit, data transmission and logic operation, and transmit the information of the two safety shoes through Bluetooth; the operation chip 201a is used for data processing and storage, calculating the electromagnetic induction intensity value, and logically calculating the step voltage value. At the same time, it sends control signals to other modules.

[0042] Among them, the driving component 402 senses the vibration and pace rhythm of human walking, and the intelligent logic judges the state of the person leaving the ground with one foot. When the walking vibration or pace rhythm is sensed, the driving component 402 is started. When the walking vibration or pace rhythm cannot be sensed for a period of time, the driving component 402 is logically operated and judged with the induction strength of the single shoe and / or the step voltage value. When a certain condition is met, such as the induction voltage values ​​of both safety shoes cannot be detected at the same time, the driving component 402 is automatically turned off. When the person puts his feet together in the dangerous area, any safety shoe can still monitor a large electromagnetic induction intensity, and the safety shoe does not turn off and continues to alarm. If one foot is suspended off the ground for a long time and the electromagnetic strength of the ground cannot be sensed, the intelligent judgment turns off the alarm.

[0043] The front and rear soles 101 communicate in real time via Bluetooth, and the induced voltage difference between the two connection pads 101a is calculated through the circuit board 201 and the computing chip 201a inside the sole 101. A connecting battery 401b is provided inside the heel 101b for powering the safety shoes.

[0044] Usage process: When electrical personnel step into a dangerous area with high voltage intensity, the induction coil 301a under the connection pad 101a will sense the voltage. After the induction coil 301a senses the voltage, the induction coil 301a will transmit the signal to the circuit board 201 and the computing chip 201a through the second connecting cable 203. After the circuit board 201 and the computing chip 201a calculate, the circuit board 201 and the computing chip 201a will drive the driving member 402 to vibrate, thereby performing a vibration alarm to warn the electrical personnel to stay away from the dangerous area.

[0045] Example 3, reference Figure 1 to Figure 2 , which is the third embodiment of the present invention, and this embodiment provides a wearable device for non-contact measurement of step voltage, which includes a warning component 500 and also includes a control cable 501 arranged at one end of the shoe toe 103, the control cable 501 is electrically connected to the induction coil 301a, the control cable 501 is connected to the alarm indicator light 501a, and a fixed steel plate 502 is provided at one end of the shoe toe 103.

[0046] Among them, the vibration alarm through the warning component 500 and the driving component 402 includes multiple alarm indicator lights 501a and vibration motors. The alarm indicator lights 501a are located on the toe and are connected to the control circuit of the toe 103 through the alarm indicator lights 501a. The driving component 402 is located in the middle of the sole 101, and the vibration is transmitted to the human body through the touch of the sole.

[0047] The warning indicator light 501 a is evenly laid on one end of the control cable 501 .

[0048] Among them, when the personnel evacuate the dangerous area, the electromagnetic field strength and step voltage of both feet are detected to be lower than the threshold, the alarm indicator 501a and the driving element 402 stop flashing and vibrating alarms, indicating that they have entered the safe area. When the personnel continue to enter the dangerous area, the step voltage is detected to be continuously higher than the safety voltage of 36V, and the safety shoes increase the flash intensity and vibration alarm frequency; when the personnel put their feet together in the dangerous area, although the step voltage is detected to be very small, a single safety shoe can still monitor a large electromagnetic field strength, and the LED red light continues to be on to alarm.

[0049] Usage process: When the induction coil 301a senses a high-intensity voltage and transmits it to the circuit board 201, after the circuit board 201 performs calculations, the circuit board 201 will also transmit the signal to the first connecting cable 202 and energize the first connecting cable 202. The first connecting cable 202 then transmits the power to the control cable 501. After the control cable 501 is energized, the multiple alarm indicator lights 501a connected to the control cable 501 will emit a constant light alarm, thereby alerting electrical personnel to ensure that they stay away from dangerous areas.
