Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electromagnetic wave monitoring apparatus and an electromagnetic wave monitoring method, and more particularly, to a portable electromagnetic wave monitoring apparatus and an electromagnetic wave monitoring apparatus capable of detecting and reporting the presence or absence of a weak electromagnetic wave without a power supply. It concerns monitoring methods.

[0002]

2. Description of the Related Art Conventionally, in portable radio communication equipment such as a mobile phone, a car phone, a PHS, a pager (registered trademark), etc., reception of a received radio wave or radio wave from its own communication device has been performed. Various methods have been proposed for easily perceiving and detecting oscillation.

For example, the configuration of an electromagnetic wave monitoring apparatus generally known in the past has a configuration as shown in FIGS. 5 and 6, and is specifically understood from the block diagram of FIG. As described above, the high-frequency coupling device 3, the detection device 4, and the display device 5 mainly including the light emitting diode are attached to the tip of the antenna 2 provided in the appropriate wireless device 1, and the light emitting diode is directly detected by the detection output of the detection device 4. Is lit.

A more specific example of the circuit configuration is shown in the circuit diagram of FIG.

That is, as understood from the circuit configuration of FIG. 6, first, a predetermined electromagnetic wave is emitted from the wireless device 1 into the air via the antenna 2 or an incoming electromagnetic wave causes the antenna 2 to resonate. In other words, when the wireless device 1 is transmitting the electromagnetic wave by itself or receiving the electromagnetic wave received by itself, the wireless communication device 1 performs transmission including the antenna by the coupling device 3 described above. The electromagnetic wave flowing through the path 6 is converted into, for example, an AC electric signal, and the AC electric signal is converted by the detection device 4 into a DC electric signal such as a DC or a pulsating current, a DC composed of a pulse, or a DC in which an AC component is superimposed. After being converted to L, which is an example of the predetermined display device 5 by the DC electric signal of the detection device 4.
The ED is emitting light.

However, in the conventional electromagnetic wave monitoring device, another power source is required to make the display device 5 emit light, and in the electromagnetic wave monitoring device having no other power source, Only when a high-output electromagnetic wave was used, the electromagnetic wave monitor could be driven.

That is, in the above-described conventional electromagnetic wave monitoring device, a light emitting diode is used as the normal display device 5, but at least 15 to 35 mW of power is required to light the light emitting diode. Become.

For example, when a red light emitting diode is used, a power of at least 1.5 V and 10 mA is required.
When a blue light emitting diode is used, at least 3.
5V, 10mA power is required.

Therefore, when the high frequency output of the wireless device 1 is small and the minimum power for making the diode emit light cannot be obtained, the diode does not turn on.

Therefore, in this case, as described above, it is necessary to separately mount a battery and a battery, which not only hinders miniaturization and weight reduction of the electromagnetic wave monitor itself, but also complicates the circuit configuration. Therefore, it may cause an increase in cost.

On the other hand, the minimum output of the wireless device for lighting the light emitting diode is required to be 150 to 350 mW when the total efficiency of the coupling device and the detection device is 10%.

For this reason, the conventional electromagnetic wave monitoring method described above can be applied only to a wireless device having a relatively large output, and in many other wireless communication devices, a separate power supply is used. It was necessary to install the equipment.

For example, there are many types of wireless communication devices, which are currently used in various fields. 1. Commercial broadcasting devices such as radio broadcasting and television broadcasting 2. Business radio equipment such as railway radio, aviation radio, police radio, disaster prevention radio, etc. 4. Portable wireless control device such as radio control (registered trademark), wireless remote control, etc. 4 Mobile wireless such as mobile phone, amateur radio, transceiver, etc. There are others. Since the power of the wireless devices 3 and 4 is supplied from a battery, the high-frequency output cannot be increased due to limitations on the available time and the like.

[0014] Their high frequency output is 100
mW or less, a specific low-power wireless remote controller or transceiver is 10 mW or less, and an amateur radio transceiver is a small output with a power of 100 mW or less. Therefore, the output value required for the minimum output of the wireless device for lighting the light emitting diode It is a much smaller value.

There are analog and digital types of mobile phones of about 800 mW, but 10 mW for simple mobile phones such as PHS, and the latest CDMA type uses advanced wireless communication technology to make use of the reception level from base stations. In some cases, the high-frequency output is controlled to 1 mW or less.

Therefore, in the above-mentioned conventional electromagnetic wave monitoring device, such a weak electromagnetic wave did not operate by the non-power supply system.

However, wireless devices with a high-frequency output of about 100 mW are expected to become smaller in the future, and there is a demand for confirming whether or not a proper wireless device is actually emitting radio waves.

For example, in a hospital or the like, the electromagnetic wave may have an adverse effect on the human body, causing a malfunction of precision electronic equipment, which is a social problem. Has been requested.

[0019]

Although the capacitor is not particularly limited, it is usually desirable to use a capacitor having a large capacity.

Further, a secondary storage battery can be used as the power storage means 7 in the present invention.

FIGS. 19 to 23 show specific examples of the electric storage means 7 which can be used in the electromagnetic wave monitoring device 100 according to the present invention.

That is, FIG. 19 shows an example in which the capacity of the capacitor C4 is large, and the power storage means is combined with the resistor R1 to form a long charging time.

On the other hand, FIG. 20 shows three capacitors (C4 and C4).

The electromagnetic wave monitoring device 10 according to the present invention

Another preferred example of the notifying means 5 in the present invention is a resistor R as shown in FIG.

By using a discharge lamp driven at a low voltage in the present invention, the switch means 8 can be omitted.

Further, as the physical vibration device, a known vibration mechanism which is convenient for the visually impaired or the like and is driven by an electromagnet, an eccentric motor or the like can be used.

As is apparent from the above description, the electromagnetic wave monitoring apparatus 100 according to the present invention does not require any special power supply such as a battery and a battery, and is driven without a power supply.

Further, it is desirable that the electromagnetic wave monitoring device 100 according to the present invention is configured to be small, light, and portable.

On the other hand, since the electromagnetic wave monitoring apparatus 100 according to the present invention detects weak electromagnetic waves and uses them in combination with the boosting means or the N-folding means from the above configuration, it does not need to have a power supply. It is possible to accurately detect the presence of a weak electromagnetic wave of about several microwatts.

Hereinafter, the operation of one embodiment of the electromagnetic wave monitoring apparatus 100 according to the present invention will be described in detail with reference to FIGS.

FIG. 3 is a timing chart showing the operation principle of one embodiment of the electromagnetic wave monitoring apparatus 100 according to the present invention shown in the block diagram of FIG.

That is, in FIG. 2, the coil L1 and the capacitance C
1 is excited by a high-frequency current from the antenna 2 of the wireless device 1 to generate a high-frequency voltage at both ends of the resonance circuit 3.

This high-frequency voltage is converted into a direct current by the detector 4. The detection means 4 in FIG. 2 constitutes a detection means 4 in which a detection function and a voltage doubler function are integrated, and has two capacitors (C2, C3) and two 2 shows a double voltage detector including diodes (D1, D2).

Accordingly, the voltage detected by the double voltage device 4 is twice the voltage of the high frequency signal which is the input electric signal.

This DC voltage, which is often a pulse voltage, charges the capacitor C4 of the storage means 7.

At this time, the voltage change of the capacitor C4 is obtained by the following equation.

First, assuming that the amount of electric charge Q stored in C4 is a flowing current I and the time is t, Q = Ixt (1) When the capacitance of C4 is C, the voltage generated in C4 is V = Q / C (2) From the above equations (1) and (2), V = (Ixt) / C (3) From this equation, it can be seen that the voltage of C4 increases with time.

On the other hand, in the switching device, positive feedback is applied to the common-mode amplifier composed of Q1 and Q2 through R3. Therefore, when Q1 becomes active at least, Q2 is quickly shifted to the cutoff state, and Q1 is rapidly saturated through R4 and R3.

Here, the voltage of C4 is divided by R1, R2 and R3 and applied to the base of Q1.

The voltage value Von of C4 required to activate Q1 is obtained from the following equation.

That is, assuming that the base voltage required to make Q1 active is Vbe1, Q2 is in a saturated state immediately before, so that Vbe1 = Vonｏｎ (R2 ・ R3) / (R1 ・ R2 + R1 ・ R3 + R2 ・ R3) (4) Therefore, Von = Vbe1 · (1 + R1 / R2 + R1 / R3) (5) Accordingly, when the voltage of C4 rises with time and reaches Von, Q1 rapidly shifts to a saturated state and the LED of the display device emits light. Let it.

At this time, the electric charge stored in C4 becomes LE
Since the voltage is discharged through D and Q1, the voltage of C4 decreases,
When the voltage reaches a certain voltage Voff, Q1 rapidly becomes inactive and Q2 becomes saturated.

Immediately before this, since Q2 is in the cutoff state, V2
Off is as follows: Voff = Vbe1 · (1 + R1 / R2 + R3 · R4 / (R2 · (R3 + R4))) (6) As can be seen from equations (5) and (6), Von always takes a value higher than Voff.

Therefore, as can be seen from the timing chart of FIG. 3, the voltage of the capacitor C4 repeatedly changes between Von and Voff.

In the meantime, the LED connected to Q1 repeats blinking because Q1 repeatedly performs the saturation and cutoff states.

However, a specific voltage (L
Von must be set to a voltage higher than Vled since it does not light unless it is higher than Vled (determined by the type of ED).

The voltage Vc of the capacitor C4 is Vle
Voff is set to a voltage slightly higher than Vled because it does not fall below d.

As is clear from the timing chart of FIG. 4, the time Toff during which C4 is charged is calculated from the equation (3) assuming that the charging current is Ichg. Toff = C.Von / Ichg (7) That is, (7) The equation is a time when the initial voltage of C4 starts from 0 volt, and means a delay time from when the radio wave transmission is started to when the LED is first turned on.

The voltage of C4 once reaches Von and the LED is turned on is Voff, so that Toff in the normal state is turned off.
Is Toff = C · (Von−Voff) / Ichg (8) Also, when the LED is lit, the current flowing through the LED is Idis. Ton = C · (Von−Voff) / Idis (9) , And the LED blinks in a cycle of Toff + Ton time.

As can be seen from the above equation, the time of Toff is inversely proportional to the charging current Ichg. Since this Ichg is proportional to the high-frequency current detected by the coupling device, it increases as the high-frequency output of the wireless device increases, and decreases as the high-frequency output decreases, so that the magnitude and fluctuation of the high-frequency output can be confirmed by the blinking speed of the LED.

As is clear from the above description, the electromagnetic wave monitoring method according to the present invention converts, for example, a weak electromagnetic wave flowing through the transmission line 6 into an electric signal via the coupling means 3 and then detects the electric signal. The output is increased at the same time as the detection using the means 4, and the electric signal with the increased output is temporarily stored in the power storage means 7, and when the voltage of the power storage means 7 reaches a predetermined voltage, the switch is turned on. This is an electromagnetic wave monitoring method configured to drive the notification means 5 via the means 8.

[0093] In the electromagnetic wave monitoring method according to the present invention, it is desirable that the notification means 5 is configured to be driven without a power supply.

Further, in the electromagnetic wave monitoring method according to the present invention, the electric signal output from the coupling means 3 is a voltage, and the detection means 4 detects the voltage signal of the coupling means 3 and simultaneously outputs N. It is also preferable to be configured to generate a doubled output signal.

It is preferable that the transmission line 6 used in the electromagnetic wave monitoring method according to the present invention includes the antenna 2, and the notifying means 5 is provided for transmitting light, voice, sound wave, and physical vibration. It is desirable to display the presence or absence of the electromagnetic wave by using any one as a medium.

It is preferable that the switch means 8 used in the electromagnetic wave monitoring method according to the present invention has a function of intermittently driving the notification means 5.

Further, it is desirable that the switch means 8 be configured to drive the notification means 5 in response to the state of charge of the power storage means 7.

Next, another specific example of the electromagnetic wave monitor device 100 according to the present invention will be described with reference to FIGS.

That is, FIG. 30 is a block diagram showing another specific example of the electromagnetic wave monitoring device 100 according to the present invention. The difference from the configuration of FIG. 2 is that the detection means 4 and the power storage means 7 or An N-fold voltage detecting means shown in FIG. 11, in this case, a quadrupling voltage detecting means 32 is further inserted between the switch means 8 and the switch means 8.

By adopting such a configuration, when the DC voltage output from the detecting means 4 is a pulse voltage or a pulsating voltage, the N-fold voltage detecting means 32 is inserted in series to increase the sensitivity. It is possible to further improve.

Also, by employing the circuit configuration of FIG. 30, the detection voltage which is eight times as high as the input voltage by the detection means 4 using the eight times voltage detection means 4 is further applied to the four times voltage. By passing through the detection means, a voltage corresponding to 8 × 2 = 16 times voltage detection is obtained.

In this case, the number of diodes is only 8 + 4 = 12. In the case where 16-fold voltage rectification is obtained by the conventional method, 16 diodes are necessary. Therefore, it is possible to omit four diodes. This contributes to cost reduction, miniaturization, and weight reduction.

FIG. 31 (A), FIG. 31 (B), FIG.
(C), FIG. 31 (D), and FIG. 31 (E) show output voltage waveforms at points A, C, D, and B in the circuit configuration of FIG. 30, respectively. , The input voltage at point A is doubled.

In the quadruple voltage detecting means 32 in FIG. 30, since the waveforms at the points A and C are the same, the capacitor C1 and the diode D0 can be omitted.

The quadruple voltage detecting means in FIG.
Generally, when an AC is used for the input, an output voltage four times as high as the input voltage is obtained, but when a DC is used as the input, an output voltage twice as high as the input voltage is obtained. Is something that can be done.

On the other hand, since the equivalent capacitance of the diode used in the detecting means 4 becomes a load of the coupling means 3,
The 16-fold voltage rectification in the conventional manner will significantly reduce the efficiency of the coupling means at high frequencies.

In order to improve the disadvantage, as another specific example, it is desirable to further insert a suitable boosting means between the switch means 8 and the display means 5 in the above specific example.

The structure of another specific example of the present invention will be described below with reference to FIGS.

In other words, in the specific example shown below, as shown in FIG. 32, the input minute voltage is boosted to a predetermined value by using the detection means 4 which also serves as the first boosting means. After that, the DC voltage stored in the power storage means 7 is temporarily stored in the power storage means 7, and then the DC voltage charged in the power storage means 7 is converted into an appropriate AC wave component using the first switch means 8. And the voltage boosted by the stored voltage boosting means 40 is supplied to the notifying means 5 directly or via the second switch means 41. .

In this embodiment, the inductor means 25
Is composed of at least two coils, and the first switch means 8
The primary coil and the secondary coil are connected such that the pulse voltage input to the primary coil is boosted to a desired magnification through the second coil.
It is desirable to adjust the number of turns of the next coil.

Further, the N-fold voltage rectifying means 23, the second power storage means 24, and the second switch means 4 in the present embodiment.
The configuration of No. 1 is the same as above.

The discharge lamp 31 is desirably connected to both ends of one coil of the inductor means 25.

That is, this embodiment is characterized in that the storage voltage step-up means 40 is constituted only by the inductor means 25, and the inductor means 25 is N times larger than the above-described embodiments. The pressure detection means 23, the power storage means 24 and the second switch means 41 are also used.

Therefore, in this embodiment, the circuit configuration is simplified, and miniaturization, high speed, and efficiency can be achieved.

On the other hand, FIG. 36 shows a configuration according to a fourth embodiment which is an improvement of the third embodiment. In FIG. 36, the switch means 8 connected to the power storage means 7 and the switch means A diode 26 and a capacitor 2 are connected to both ends of one coil constituting the inductor means 25 connected to the inductor 8.

That is, in the present embodiment, the voltage charged in the power storage means 7 is intermittently driven to drive the switch means 8 so that the storage voltage boosting means 40 comprises one coil. It is configured to discharge at a stretch via the inductor means 25 and to make the discharge lamp 31 as the notification means 5 blink intermittently.

Accordingly, in this embodiment, the circuit configuration is simplified, and miniaturization, high speed, and efficiency can be achieved.

Next, another embodiment of the present invention will be described in detail with reference to the drawings.

That is, the above-described specific example of the present invention relates to an electromagnetic wave monitoring device and an electromagnetic wave monitoring method having the above-described configuration. For example, the electromagnetic wave monitoring device is used for an antenna of a portable communication device or the like. It was used by attaching to the tip.

For example, as shown in FIG. 38, the electromagnetic wave monitoring device 100 described above is attached to the tip of the antenna 2 connected to the portable communication device 1 via the feeding point 9 to monitor the electromagnetic wave. Therefore, the electromagnetic wave monitor device is electrically (statically or electromagnetically) coupled to the electromagnetic wave monitor device at the tip of the antenna, and the operation principal of the electromagnetic wave monitor device in such an embodiment is In addition, a part or more of the electromagnetic wave monitor device 100 emits electromagnetic waves of a certain degree or more into the air, thereby operating the internal display device.

In this specific example, for example, when the portable communication device is located far from the base station, the received radio wave is weak. When the portable communication device is placed close to the base station, the received radio wave is strong, so the antenna of the portable communication device should be stored in the housing. This operation is performed to attenuate the receiving sensitivity appropriately.

For example, as shown in FIG. 38, the electromagnetic wave monitoring apparatus 100 described above is attached to the tip of the antenna 2 connected to the portable communication device 52 via the feeding point 9 to monitor the electromagnetic wave. Therefore, the electromagnetic wave monitor device is electrically (statically or electromagnetically) coupled to the electromagnetic wave monitor device at the tip of the antenna, and the operation principle of the electromagnetic wave monitor device in such an embodiment is as follows. In addition, a part or more of the electromagnetic wave monitor device 100 emits electromagnetic waves of a certain degree or more into the air, thereby operating the internal display device.

Now, taking a mobile phone as an example of a portable communication device as an example, the most recent wireless communication system is a CD.
As typified by MA, the transmission power of a terminal device increases or decreases according to a command from the base station so that the reception intensity at the base station is always constant.

More specifically, in a place far from the base station, or in a place where the condition of the radio wave is poor, such as in a valley of a building or inside a building, the reception level is specified because the radio wave does not sufficiently reach the base station. Instead, the terminal issues a command to the terminal to increase the transmission power.

On the other hand, in a place where the radio wave condition is good such as a place close to the base station or a place with good visibility to the base station, the reception level at the base station becomes larger than a prescribed value.
Since this affects communication with other terminals, the terminal issues a command to reduce transmission power.

As can be understood from the above, the transmission power from the terminal equipment becomes extremely small depending on the environment. In the above-described electromagnetic wave monitoring device of the embodiment of the present invention, in the above-mentioned new communication system, In some cases, it is conceivable that the electromagnetic wave monitoring device may not be able to obtain enough power to drive a display device.

Therefore, in the electromagnetic wave monitoring device and the electromagnetic wave monitoring method according to the specific example of the present invention described above, even if a new communication system in such portable communication equipment is used, At the same time, it is necessary to create a state in which the compatibility between the antenna and the electromagnetic wave monitor circuit can be more easily achieved.

Therefore, in another aspect of the present invention, in the new communication system, it is possible to solve the above-described problem and to create a state in which the antenna and the electromagnetic wave monitor circuit can be more easily matched. It aims to realize a portable communication device that can be used.

The basic structure and the principle of the portable communication device of this embodiment according to the present invention are as shown in FIGS. 39 and 40. Specifically, the housing unit 50, the antenna unit 2, and the housing unit A receiving / transmitting circuit unit 51 including a power supply incorporated in the housing 50;
0 is a portable communication device 52 including the antenna unit 2 and a power supply unit 9 which can be electrically connected to the antenna unit 2, wherein the antenna unit 2 is a conductive communication device covered with an insulator 53. One end portion 56 of the antenna section 2 is electrically insulated from the conductive core member 54 and is electrically connected to the power supply section 9 to hold the antenna 9. A first conductive holding member 55 is provided, and the other end 58 of the antenna unit 2 is electrically connected to the conductive core member 54, electrically connected to the power supply unit 9, and The second conductive holding member 59 for holding the antenna 2 is provided, and the end 56 of the antenna 2 where the first conductive core member 54 is provided is described in any of the above specific examples. The installed electromagnetic wave monitor device 100 The first terminal section 60 of the electromagnetic wave monitor device 100 is connected to the end 56 of the conductive core member 54 of the antenna section 2, while the electromagnetic wave monitor apparatus 100 is connected to the first terminal section 60. Another terminal 61 of the device 100 is a portable communication device 52 connected to the first conductive holding member 55.

In this specific example, FIG. 39 shows an example in which the antenna section 2 is housed in the housing section 50, in which the radio wave is strong.

In this state, the first conductive holding member 55 provided at the distal end portion 56 of the antenna section 2 is connected to the feeding section 9 via washer means 57 having appropriate conductivity, and The second conductive holding member 59 provided at the lower end 58 of the second communication device 52 is in an open state, and when radio waves are received, the portable communication device 52
Is to perform an operation to reduce the transmission power so that the reception intensity at the base station becomes constant. However, a return current as shown by an arrow A in FIG. 39 is formed, and the return current is generated by the antenna unit. Electromagnetic wave monitoring device 10 connected to the tip of 2
0, it is possible to drive the display device of the electromagnetic wave monitor device. On the other hand, as shown in FIG. The second conductive holding member 59 provided at the lower end portion 58 of the section 2 is electrically connected to the power supply section 9, and as a result, a current flows as indicated by an arrow B. Since the current was small, it was impossible to drive the display device of the electromagnetic wave monitor device 100.

Therefore, in another specific example of the present invention,
This configuration employs a configuration as shown in FIG.

That is, in FIG. 41, the housing unit 50, the antenna unit 2, a receiving / transmitting circuit unit 51 including a power supply built in the housing unit 50, and connected to the receiving / transmitting circuit unit 51, A portable communication device 52 including the antenna unit 2 provided in a part of the unit 50 and a power supply unit 9 that can be electrically connected, and the antenna unit 2 is covered with an insulator 53.

4 and a first conductive holding member 55 that is electrically connected to the power feeding unit 9 and holds the antenna unit 2. The first conductive holding member 55 is provided at the other end 58 of the antenna unit 2. Is provided with a second conductive holding member 59 that is electrically connected to the conductive core member 54, is electrically connected to the power supply unit 9, and holds the antenna. The part 9 shows a portable communication device 52 having an electromagnetic wave monitoring device with which the external conductor 10 provided with the electromagnetic wave monitoring device 100 according to any one of claims 1 to 35 is abutted.

However, since the external conductor 10 is connected between the feeding point 9 and the antenna unit 2, the power P ′ is
Will be consumed.

Therefore, the power P supplied to the antenna
Since P = Pt−P ′, the reception strength of the base station is reduced by P ′, so that the terminal is instructed to increase the transmission power further.

Therefore, if the power supply point 9 and the electromagnetic wave monitor 100 according to the present invention are coupled in the middle of the antenna section 2, it is possible to extract extra power by P '.

As a result, the circuit of the electromagnetic wave monitor is simplified and the cost is reduced.

Further, the display device in the electromagnetic wave monitor device can incorporate a device having a high function, thereby increasing the commercial value.

In the conventional method, similarly, at the time of storage,
Although the power supplied increases due to a substantial decrease in the efficiency of the antenna,
Since the electromagnetic wave monitoring device is not located between the feeding point 9 and the antenna, the power corresponding to P ′ is wasted, and no high-frequency current flows through the electromagnetic wave monitoring unit 100 as shown in FIG.

On the other hand, in the specific example shown in FIG. 41, one end of the external conductor 10 formed separately from the antenna section 2 is connected from the feeding point 9 of the radio apparatus to the antenna section 2.

Further, in this specific example, it is possible to arrange a light emitting device on a part or all of the conductor 10 in addition to the display means of the electromagnetic wave monitoring device.

In particular, since the portion corresponding to the substantial antenna in such a state is only the circuit portion of the electromagnetic wave monitoring device, the efficiency of the antenna is reduced, and a considerable amount of power is supplied to the electromagnetic wave monitoring portion. become.

Thus, the circuit of the electromagnetic wave monitor is simplified and the cost is reduced.

Further, a device having a high function can be incorporated by the display device in the electromagnetic wave monitor device, and the commercial value can be enhanced.

Also, in the conventional method, similarly, at the time of storage,

It is desirable to adopt a configuration that comes close to

For example, a conductor 10 having a predetermined length and a small width is attached to a part of the antenna part 2, and a part thereof is bent and dropped downward along the side wall part of the housing. It is also preferable to configure in such a manner.
