Description

Electric field sensing output device

The present invention relates to an electric field sensing output device excellent in simplicity, quick report, accuracy, and non-invasiveness for outputting electric field strength or direction for simple and accurate measurement and detection.

A technology or machine that utilizes or accompanies the electric field is widely used. In addition, due to natural phenomena such as static electricity or lightning strikes, strong electric fields can also occur. However, since the electric field cannot be visually recognized, even an expert or a familiar person cannot easily and quickly grasp the target electric field. It is also difficult for users of technology or machines, and those who do not have professional knowledge about electric fields, to understand and imagine the electric field of an object. For example, in a potential therapy device that supplies a high voltage to an insulated human body and uses the biological stimulation generated by the electrical field formed around the human body for treatment, the person to be treated must recognize that an electric field is formed around the human body. difficult.

Conventional methods for measuring the strength or direction of an electric field are mainly classified into the following two. In the first method, a probe using a probe capable of sensing an electric field is known, and a metal probe is connected to a detection system through a metal cable, and a configuration of an electric field measurement device is known. In addition, it is also known to suppress invasion It is related to the technology related to the electric field measuring device of the optical detection system in which the tip end portion of the electro-optical crystal is connected to the optical detection cable with an optical fiber cable (see, for example, Patent Document 1). These techniques involve inserting the tip of the probe into the electric field to perform electric field sensing or measurement. In addition, in the second method, there is known a value obtained by measuring the potential of a point to be a reference, and measuring the difference (voltage) from the reference potential for one point near the measurement object and dividing it by the distance between the two points Set as the electric field method. In addition, a technique related to an electroscope that senses and notifies the formed electric field is known (see, for example, Patent Document 2). This technology determines whether there is an electric field.

In addition, the potential therapy device 200 is chair-shaped as shown in FIG. Applied voltage generator 2004. The subject is seated on a chair, placing the body in the electric field generated between the upper electrode 2001 and the seat electrode 2002, thereby receiving the patient (see, for example, Patent Document 3). Here, the voltage generated by the voltage generator 2004 can be adjusted by a human hand.

However, if the metal probe system is inserted into the electric field, the measured electric field will be disturbed by the probe or the cable, and will be highly invasive. Here, intrusiveness refers to a person whose measured electric field is chaotic due to external factors.

In the technique described in Patent Document 1, although the intrusiveness is reduced, the configuration is complicated and the device is enlarged, so it is difficult to carry and not simple. In addition, in the technique described in Patent Document 2, the presence or absence of an electric field is discriminated, and the person cannot grasp the strength by accurately measuring the electric field.

In addition, the electrodes of the potential therapy device 200 are basically fixed at a certain position, so even if the voltage between the electrodes is constant, it is applied to the body / type of the person to be treated (height, sitting height, weight, obesity, etc.) The intensity of the electric field of each part of the subject will change, and the treatment effect will also be uneven, but so far there is no proper detection means and electric field adjustment means.

For example, FIG. 14 is a conceptual diagram of the measurement experiment of the electric field strength in various parts of the human body caused by the potential treatment device 200. In the potential therapy device 200 used for measurement, the voltage of 4500 V generated by the voltage generator 2004 is input to the upper electrode 2001 and the seat electrode 2002 with a phase shift of 180 degrees, and the lower electrode 2003 is grounded.

Next, using electro-optic crystals such as Bi ₁₂ SiO ₂₀ and photoelectric field sensors using optical fibers, the body surface of the various parts of the human body (head, eyebrows, abdomen, knees, feet) shown in the figure are measured, And the electric field intensity in the place where the isolated surface is about 12 cm. The English letters in the figure indicate the measurement point, A and B are the head, C and D are near the eyebrow, E and F are the abdomen, G and H are the knees, I and J are the feet, A, C, E and G , I is near the body surface, B, D, F, H, J is 12cm away from the body surface.

Here, the measurement axis of the photoelectric field sensor (measurement of the electric field of the component in the same direction as the axis) is set in the direction of the arrow in the figure.

In addition, the body of the subject at this time was 175 cm tall, 68 kg in weight, 20% body fat percentage, and the subsequent body mass index was 22.2.

The experimental results are shown in Table 1.

From this result, it can be seen that the electric field intensity will be greatly changed by the distance from each body part or body surface of the subject. In this experiment, although only one person was treated, it can be easily guessed that When the type is different, the measured electric field strength will change.

Therefore, the object of the present invention is to provide a simple and accurate measurement and output of the electric field strength or direction. The user can easily grasp the electric field strength or direction. Therefore, the electric field sensing output is excellent in simplicity, quick report, accuracy, and non-invasiveness.

(Embodiment 1)

1 to 6 show Embodiment 1 of the present invention. The electric field sensing output device 10 is used to notify the electric field intensity by inserting into the electric field. As shown in FIG. 1, it mainly includes: electrodes 1 ₁ , 1 ₂ , an imaginary grounded current detector 2, and an LED 3 as an output means ₁ ~ 3 ₄ , battery 4 as power source, switch 5, and grip 6.

Electrodes _{11, 12} in FIG. 1 line, as shown in FIG. 2, relative to the plate electrodes disposed substantially parallel with the make, the electrode spacing d, as the electrode area s settings. Embodiment the electrodes _{11, 12} based so as to be the virtual ground type current detector 2, LED3 ₁ ~ 3 _4, the battery 4, and the switch 5 is accommodated is formed in the space in the ₁₂ between the electrodes ₁₁ is set Its size (electrode interval d, electrode area s), shape. In addition, as shown in FIG. 3, the length L of the electrode interval d with respect to the electric field of the measurement object can be regarded as a certain value is very small, for example, the length L is several tens of cm, and is set to several cm or less. Further, the electrode area S with respect to the electric field of the measurement target area S may be regarded as a constant value is very small, for example with respect to the area number s 10cm ^2, is set to several cm ^2. In the electrodes _{11, 12} are connected to lead lines E _1, E _2.

Virtual ground line type current detector 2 shown in Figure 1, is disposed on the electrode _11, a _{2, a} detecting electrode 1, a direct current or alternating current is induced by 1 ₂ to the charge generated by the It consists of a current amplifier and detector with virtual grounding characteristics. An input terminal (not shown) virtual ground type current detector 2 is connected to the lines _{11, 12} are connected to wiring electrodes E _1, E _2. Whereby, after the two virtual ground lines of said switch type current detector 5 is formed to "open" status, and if the electric field sensing means sensing the output electric field standing at 10, the electrodes _{11, 12} lines were induced charges of different polarities , Becomes to detect the current generated at that time. At this time, by the virtual ground characteristics of virtual ground type current detector 2, the electrodes _{11, 12} does not generate a potential difference, the electric field sensing system output device 10 may be considered to operate as a metal plate of thickness d. The imaginary grounded current detector 2 outputs the detected current value to the LEDs 3 ₁ to 3 ₄ side.

Here, the virtual ground characteristic refers to a characteristic of an operational amplifier (Operational Amplifier), and the voltages at the input terminals of the non-inverting input (+) and the inverting input (-) are always equal, that is, they become the same potential. That is, the virtual ground terminal of the input current detector type 2 (non-inverting input (+) and the inverting input (-)) is connected to the lines connected to the electrode _11, the wire E 1 _{2 1 2} E, Therefore, there is no potential difference between the electrodes 1 ₁ and 1 ₂ .

If the electric field measured by the virtual ground type current detector 2 is AC, the actual value of the current is calculated by the following formula. Here, I _rms is the effective value of the current, f is the frequency, ε is the dielectric coefficient, S is the electrode area, and E _rms is the effective value of the electric field strength. That is, the calculated effective value I _rms of the current is proportional to the effective value E _rms of the electric field strength.

In addition, if the electric field measured by the virtual ground current detector 2 is DC, the current value is calculated by the following formula. Here, I is a current value, t is time, ε is a dielectric coefficient, s is an electrode area, and E (t) is an electric field strength. That is, the time integrated value of the calculated current value I is proportional to the electric field strength E (t).

Means the output means is disposed, a _2, a display device for outputting the electric field strength by the corresponding virtual ground's current type current detector 2 is detected, for example, include a LED or a liquid crystal comprising an electrode _11, or The person who outputs (transmits) the electric field strength corresponding to the detected current as data to the external display device. In the first embodiment, the output means are LEDs 3 ₁ to 3 ₄ , which are arranged between the electrodes 1 ₁ and 12 as shown in FIG. ₂ and correspond to the current detected by the virtual ground type current detector 2 The electric field strength is output to outsiders. In this embodiment _1, LED3 1 ~ 3 ₄ 4 arranged in line ₁₁ is disposed at one end side of the electrode _12. Specifically, for example, if the current value detected by the imaginary ground type current detector 2 is zero, any LEDs 3 ₁ to 3 ₄ do not light, and the current detected by the imaginary ground type current detector 2 When the value is greater than zero, the number of LED3 ₁ ~ 3 ₄ lights will increase or decrease according to the current value, that is, the electric field strength. In other words, according to the number of LEDs 3 ₁ to 3 ₄ lighting, the presence or absence of the electric field or the detected electric field intensity can be recognized. Here, FIG. 2 shows a state in which only LED3 _{1 is} turned on, and LED3 ₂ to 3 _{4 are} not turned on (turned off).

Cell lines 4 shown in Figure 2, is disposed in the electrode 1 _1, 1 _2, the virtual ground type of current detector 2 and LED3 ₁ ~ 3 ₄ by supplying electric power, for example, is constituted by a coin type battery.

2 based switch 5, is disposed in the electrode 1 _1, 1 _2, the electric field sensing output apparatus 10 is inserted before the electric field of the object is set to "open" status, set to "closed" end use status. In addition to the measurement, the switch 5 is set to the "closed" state, thereby preventing damage caused by an overcurrent caused by a non-formed electric field such as a virtual ground type current detector 2 or LEDs 3 ₁ to 3 ₄ . The switch 5 can be opened and closed by the user and linked with the power switch.

The grip portion 6 constituting the lines to the insulator plate, is disposed on the lower electrode _12, the electrode ₁₂ is greater than, outwardly projecting side.

If the electric field sensing output device 10 configured as shown above, for example, as shown in FIG. 3, is left in the electric field formed by the electrodes 100 ₁ and 100 ₂ , it is detected that the electrodes 1 ₁ and ₁₂ are sensed The electric current generated by the electric charge is notified of the electric field strength by the lighting of LEDs 3 ₁ to 3 ₄ . Here, the electrodes 100 ₁ and 100 ₂ are each constituted by a flat plate, and are arranged such that the two electrodes 100 ₁ and 100 ₂ form a predetermined angle. An electric field in the direction of the arrow in the figure is formed between the two electrodes 100 ₁ and 100 ₂ .

Next, the usage method and function of the electric field sensing output device 10 configured as described above will be described.

The method of measuring the electric field strength will be described for the case where the direction of the electric field of the measurement object is known. Here, as shown in FIG. 3, it is assumed that the direction of the electric field (arrow direction in the figure) formed by the electrodes 100 ₁ and 100 ₂ is known.

First, by the user, the switch 5 of the electric field sensing output device 10 is formed into the "on" state. Next, the electric field sensing output device 10 is inserted into the electric field with the user gripping the grip 6. In this case, the electric field sensing system output device 10 shown in FIG. 3, the electrodes _{11, 12} in opposite direction of electric field perpendicular manner as provided. At this time, the electrodes _{11, 12} lines were induced charges, current detection by the current detector virtual ground type, LED3 ₁ ~ 3 ₄ according to the magnitude of the current lighting. Next, according to the user, the electric field intensity is confirmed by the number of lights of LEDs 3 ₁ to 3 ₄ .

Next, a method of determining the direction of the electric field will be described for the case where the direction of the electric field of the measurement object is unknown. Here, as shown in FIG. 3, it is assumed that the direction of the electric field formed by the electrodes 100 ₁ and 100 ₂ is unknown.

First, by the user, the switch 5 of the electric field sensing output device 10 is formed in the "on" state, and the electric field sensing output device 10 is inserted into the electric field in the state where the grip 6 is gripped. In this case, the output direction of the electric field sensing device 10, for example, FIGS. 3 to 5 were changed as shown, is adjudged to be lit up to fix the electrode at the LED3 ₁ ~ 3 _{4 1 1,} 1 ₂ in the direction orthogonal to the form The direction is the direction of the electric field.

Specifically, when the electric field sensing output device 10 is formed in a direction shown in FIG. 3, the electrodes _{11, 12} on the induced charge polarity different from the power line becomes the maximum, thus the generated electric current becomes maximum, 4 LEDs 3 ₁ ~ 3 ₄ are illuminated. When an electric field sensing if output device 10 is formed as the direction shown in FIG. 4, the electrodes _{11, 12} on the different polarity charges induced by the inclination of the power line is reduced, and therefore the generated current based sensing field ratio The case where the measurement output device 10 is formed in the direction shown in FIG. 3 is smaller, and one LED ₃₁ is turned on. If the output field sensing device 10 is formed in the direction shown in FIG. 5, electrodes _{11, 12} due to the electric field with the same direction, thus not induced charge, so that any LED3 ₁ ~ 3 ₄ none is lit. As shown above, if the direction of the electric field sensing output device 10 is formed as shown in FIG. 3, it can be seen that the LEDs 3 ₁ to 3 ₄ are turned on at most, and the maximum electric field strength is recognized, so the recognized and current electrodes The directions of 1 ₁ and 1 ₂ are perpendicular to each other as the direction of the electric field. In addition, the direction at right angles to the direction of the electric field sensing output device 10 in FIG. 5 may be recognized as the electric field direction.

The field sensing device 10 output lines shown in Figure 3, if the electric field is opposite the direction of the electrodes _{11, 12} become disposed for perpendicular manner, the electric field becomes relatively constant value is regarded as the object distance is the distance d Since it is small, the electric field formed by the electrodes 100 ₁ and 100 ₂ does not cause confusion. That is, the intrusion becomes extremely small. Further, as shown, even in the case where the electrodes _{11, 12} in a manner opposite field direction having a predetermined angle is provided for, not disturbed by the electric field has four electrodes _{1001, 1002} are formed The whole situation. At this time, the intrusiveness becomes greater than the case where the direction of the electric field sensing output device 10 is formed as shown in FIG. 3.

As shown above, only the electric field sensing output device 10 is inserted into the electric field, and the current generated at the electrodes 1 ₁ and 1 ₂ is detected by the virtual ground type current detector 2 and the LED 3 ₁ to 3 ₄ The number of lights on can be instantly measured and notified of the electric field strength, so it is excellent in simplicity and quick reportability. In addition, the space in the electrode by a flat plate of _{11, 12} relative to the assigned formed accommodated: virtual ground type current detector 2, LED3 ₁ ~ 3 _4, the battery 4, and a switch 5, even if the electric field The sensor output device 10 is inserted into the electric field, and the measured electric field will not be disturbed, and is excellent in accuracy and non-invasiveness. Accordingly, the electrode _{11, 12} can be accommodated to the size of the virtual ground type current detector 2, LED3 ₁ ~ 3 _4, the battery 4, and the size of the switch 5. That is, the electric field sensing output device 10 can be inserted into a pocket, or mounted on clothes, or formed in a size that can be carried at any time, or miniaturized to a size that can be mounted on a fingertip.

In addition, the number of lights on the LEDs 3 ₁ to 3 ₄ can recognize the electric field intensity proportional to the detected current, so the electric field can be measured with high accuracy and displayed with high accuracy, so the electric field intensity can be grasped with high accuracy.

In addition, in the target electric field, the direction of the electric field sensing output device 10 is changed to measure the electric field intensity, and the number of lights of the LEDs 3 ₁ to 3 ₄ is compared, whereby the direction of the electric field can be recognized.

In addition, in the state of holding the holding portion 6 made of an insulator having a low dielectric constant, the electric field sensing output device 10 can be taken out and put in the electric field for measurement, so it is simple and non-invasive. different.

The electric field sensing output device 10 having the effects shown above can generate an electric field, measure the electric field intensity in a device that uses the electric field, or grasp the distribution of the electric field. Specifically, for example, it is possible to measure the strength of the electric field or grasp the distribution of the electric field during treatment, life, or work under the use of a medical device including a medical device that generates a high electric field or a potential treatment device or an operation. In addition, it is possible to measure the intensity of the electric field in a plastic molded article or an object containing powder that is excessively charged with static electricity, or to grasp the distribution of the electric field. At this time, as shown in Fig. 6, the possibility of electric shock may be set to "danger level", "warning level", etc. according to the measured electric field strength. If the electric field strength is above a predetermined value, it may also be output Alarm sound to inform.

In particular, by detecting a state where the user's human body is excessively charged with static electricity, it is possible to grasp the danger of thunder or static shock pain.

Furthermore, since the electric field sensing output device 10 is of a card type, for example, it can be inserted into a user's pocket or installed in clothes, so it can be easily carried. Therefore, the electric field sensing output device 10 can often be carried to easily measure the electric field at any time. That is, even for treatment, life, and work under the use of a medical device or a treatment device that generates a high electric field, the electric field can be easily measured at any time, so the convenience is further improved.

(Embodiment 6)

FIG. 11 is a block diagram showing a schematic configuration of Embodiment 6 of the present invention. The electric field adjustment system 70 is roughly divided into a potential treatment device 71 and an electric field sensing output device 72.

The potential treatment device 71 is configured to include a receiving means 711 and a voltage adjustment means (adjustment means) 712 in the conventional potential treatment device 200.

The receiving means 711 is a device for receiving signals and transmitting them to the voltage adjusting means 712 using communication methods such as infrared, sound wave, electric wave or wired communication. The receiving means 711 receives the signal transmitted by the electric field sensing output device 72, converts the content (current value) into an electric signal, and sends it to the voltage adjusting means 712.

The voltage adjusting means 712 adjusts the voltage generated by the voltage generator 2004 according to the current value received by the receiving means 711.

The voltage adjustment means 712 has: a memory function, a calculation function, an input function, and a control function.

The memory function is composed of a memory device such as a flash memory. In the sixth embodiment, in particular, a predetermined electric field value and past The information of the subject's physique / physique (height, sitting height, weight, obesity, etc.), and the voltage intensity (adjusted value) applied at that time.

In addition, after the treatment, information about the physique / physique of the subject and the adjusted voltage intensity are memorized.

In addition, the input function is an information processing device such as a notebook personal computer, or a portable terminal such as a smartphone, which is used to input the information of the physique / body of the subject to the memory function before the start of treatment.

The computing function is a device formed by a central processing unit (Central Processing Unit; CPU). The calculation function is to obtain the electric field strength from the current value received from the receiving means 711 according to Formula 1 or Formula 2, that is, the effective value of the electric field strength E _rms or the electric field strength E (t). Next, the strength of the electric field and the predetermined electric field value memorized by the memory function are compared to determine whether there is a difference. Then, if there is a difference, a voltage adjustment instruction is issued to the control function in such a way as to adjust the voltage to make the difference disappear. Here, to make the difference disappear does not necessarily mean that the two are completely consistent, but also included in the error range preset and memorized by the memory function. In addition, before the start of the treatment, it is searched whether the memory of the treated person whose physical shape / type is similar to or the same as the entered person / physique is in the memory function, if there is, refer to the voltage applied to the treated Intensity, and for the control function, the voltage adjustment instruction is issued in a manner adjusted to the voltage intensity.

The control function is a circuit that controls the voltage generator 2004 based on the voltage adjustment instruction sent by the arithmetic function. Here, if there is no voltage adjustment instruction from the calculation function (for example, when the memory function does not have a memory similar to or consistent with the physical / physical shape of the subject), the The voltage generator 2004 is controlled by the set voltage setting method.

The voltage adjustment means 712 repeats the above process until the difference between the electric field strength and the predetermined electric field value disappears.

Next, the electric field sensing output device 72 will be described.

The electric field sensing output device 72 of the sixth embodiment is different from the electric field sensing output device 10 of the first embodiment in that the output means is the signal sending part (transmitting means) 721 instead of the LEDs 3 ₁ to 3 ₄ . Other components are marked with the same symbols and their description is omitted.

The transmitting unit 721 is used to transmit signals to the receiving means 711 using infrared, sonic, radio or wired communication and other communication methods, and is composed of an infrared light emitting unit or the like that emits signals.

That is, if the electric field sensing output device 72 senses the electric field, the signal transmitting unit 721 will send a signal to the receiving means 711 according to a signal that varies according to the electric field intensity.

Next, the operation of the sixth embodiment and the electric field adjustment method will be described based on FIGS. 12 and 13.

The switch 5 of the electric field sensing output device 72 is formed into an open state, and the electric field sensing output device 72 is left at a position of 0 to dozens of centimeters away from each part of the body such as the head, wrist, chest, etc. of the subject (Step S1).

Next, with the input function of the potential therapy device 71, the physical / physical information (height, sitting height, weight, obesity, etc.) of the subject is memorized in the memory function (step S2).

Make the person to be treated sit on the potential treatment device 200, and make the potential treatment The device 71 is activated, and a voltage is applied between the electrodes by the voltage generator 2004 (step S3).

The arithmetic function of the voltage adjustment means 712 of the potential therapy device 71 retrieves whether there is physical / physical data similar to or consistent with the physical / physical information of the subject input to the memory function (step S4). The voltage adjustment instruction is issued to the control function by adjusting the voltage to the value of the voltage intensity stored in the memory function (step S5). On the other hand, if it does not exist, a voltage adjustment instruction is issued by applying a set voltage (step S6).

In steps S5 and S6, the voltage generator 2004 receiving the voltage adjustment instruction adjusts the voltage and applies the voltage according to the instruction.

The electric field sensing output device 72 senses the electric field applied to the body of the subject.

The signal sending part 721 of the electric field sensing output device 72 sends out a signal corresponding to the magnitude of the current.

The potential treatment device 71 receives the signal by the receiving means 711 (step S7), and measures the electric field strength by the arithmetic function of the voltage adjusting means 712 (step S8). Next, by the control function of the voltage adjustment means 712, it is determined whether there is a difference between the electric field strength and the predetermined electric field value memorized by the memory function of the voltage adjustment means 712 (step S9), and if there is a difference, it disappears (same , Or within a predetermined error range), the voltage generated by the voltage generator 2004 is adjusted (step S10).

If there is no difference between the electric field strength and the predetermined electric field value by voltage adjustment, the voltage adjustment means 712 stops the voltage adjustment, and the voltage The generator 2004 applies a regulated voltage.

If the treatment is performed at a desired time, the potential treatment device 71 is stopped (steps S11 and S12), and the switch 5 of the electric field sensing output device 72 is turned off. At this time, the physical / physical information of the subject and the adjusted voltage intensity are memorized in the memory function (step S13).

According to the sixth embodiment, regardless of the difference in the physique / type of the subject, the electric field applied to the human body can always be maintained at a predetermined intensity, so that a stable therapeutic effect can be obtained among the subjects of different physique / body type .

Next, the electric field sensing output device 72 is installed on the upper electrode 2001, and the upper electrode 2001 is moved up and down, thereby adjusting the distance between the electric field sensing output device 72 and the subject, thereby adjusting the electric field intensity. Here, the movement of the upper electrode 2001 may be automatic or manual, but if it is automatically performed, the position control is performed in conjunction with the calculation function, and the changed position of the upper electrode 2001 will be adjusted to the body of the subject / The body shape information or the adjusted voltage is memorized in the memory means, so that the efficiency of electric field adjustment can be achieved.
