[0002]

2. Description of the Related Art Conventionally, when investigating whether or not termites are eroding a house, it is common for an investigator to go under the floor or the like at the request of the landlord and conduct a visual inspection. In addition, since a landlord requests a survey after the occurrence of a termite and the discovery of a portion that has already been eroded and decayed, erosion by termites has already progressed at the time of termite survey.

In response to this problem, the present applicant applied for a termite alarm device in Japanese Patent Application No. 6-170134, filed on June 29, 1994. The termite alarm device disclosed in this application has a sensor unit in which a plurality of holes are formed in a member including cellulose, a transmitting element is provided in an opening at one end of the hole, and a receiving element is provided in the other opening, The receiving element comprises a determining unit that detects and outputs the invasion of termites when the output wave from the element is cut off, and an alarm display unit that issues an alarm based on the output from the determining unit.

[0004]

SUMMARY OF THE INVENTION The present application is a further development of the above-mentioned invention, and provides a termite detecting device capable of reliably detecting the invasion of termites and ensuring the detection result of the termite detecting device. An object of the present invention is to provide a termite alarm device that can notify a resident.

[0005]

[SUMMARY OF To this end, the termite detection apparatus according to the present invention, the case having an opening at the lower end, while leaving collision at a predetermined dimension from the opening of the case, a plurality of openings on the lower surface first attractant member formed from the guide hole, this is arranged on top of the first attractant member, and the first hole guide bore communicating with the first, with intersecting the first hole,
A second means provided with a detecting means including a transmitting element and a receiving element;
A detection unit having a hole formed therein, a second attraction member disposed above the detection unit, and a sensor unit configured by a seal member that seals between the case and the first attraction member; A sensor cover for closing the periphery of the sensor section (claim 1).

[0006] Thus, termites are attracted from the soil to the guide hole of the first attracting member buried in the soil at a predetermined depth, and the termites attracted to the first attracting member are moved to the second attracting member. In the process of being attracted by the attraction member, the inspection communicating with the guide hole is performed.
In order to pass through the first hole in the ground, the output wave transmitted from the transmitting element of the detecting means is changed. Therefore, it is detected that a termite has entered. Then, since the first attracting member can be buried in the soil at a predetermined depth, the termites that do not want to dry are easily attracted to the first attracting member. Further, since the case is sealed by sealing the space between the case of the sensor unit and the first attracting member with a sealing member, the humidity can be reduced in a high humidity environment where the termite detection device is disposed. Since it is possible to protect electric components and the like from the ground, it is possible to detect termites for a long time. The output wave is an electromagnetic wave (claim 2),
Alternatively, it is a sound wave (claim 3), and the electromagnetic wave naturally includes a radio wave, light, and the like.

Further, the detection portion is formed of a synthetic resin having a predetermined hardness.
When the termites move from the first attraction member to the second attraction member, the termites surely pass through the first hole, so that the invading termites can be reliably detected.

[0010] Further, by sowing a reference chip around the sensor section (claim 5), the rate of attracting termites can be improved. Further, since the sensor section of the termite detection device is fixed to the soil surface by a plurality of piles mounted on the attracting member (claim 6), it is possible to prevent the sensor section from falling down and tilting. In addition, detection of termites by the sensor unit can be ensured.

Further , the sensor cover has
There is a display unit for displaying the operation status (claim 7).

As described above, by providing the display unit for displaying the operating status of the sensor unit on the sensor cover, it is possible to confirm whether the sensor unit is operating simply by looking under the floor and detect termites. By changing the display of the sensor unit, the position where the termites are generated can be specified.

[0011] In addition, termite alarm device according to the present invention, the minute
A plurality of termite detection devices according to claim 1 scattered;
It aggregates the termite detection signals from the plurality of termite detection device alarm, a relay unit that outputs a termite generation signal, is installed indoors, receives the termite occurrence signal from the relay unit, a voice generation of termites And a visual warning unit for visually displaying the voice warning unit (claim 8).

[0012] With this arrangement, the detecting means detects the termites attracted by the attracting member in the sensor section arranged at a predetermined position under the floor, and the termite detection signals from the plurality of termite detection devices are collected in the relay section. . The termite detection signal collected in the relay unit is sent to the alarm unit as a termite generation signal, and warns the resident of the occurrence of termites by voice in the voice alarm unit and visual display in the visual alarm unit. In this case, the alarm unit is preferably arranged in a prominent place on the floor. However, if a plurality of termite detection devices are directly connected, the wiring becomes complicated and visually unfavorable. (E.g., at a predetermined position under the floor), and each termite detection device can be connected through this relay portion. Therefore, only one wire is required between the relay portion and the alarm portion, so that the visual neatness can be reduced. it can. In addition, the wiring from each termite detection device does not need to be pulled up on the floor, so that wiring under the floor can be easily performed.

[0013]

It is formed by a synthetic resin. Further, a flange portion 64 for fixing the sensor cover 6 to the soil surface is formed on the peripheral wall portion 61 so as to radially extend from a lower end of the peripheral wall portion 61. Further, the flange portion 64 has a bolt 13 ( A hole 65 through which a stake, a screw or the like may be formed is formed.

A cable passage hole 66 into which the connection cable 8 is inserted and fixed is formed at a predetermined position on the peripheral edge of the upper end opening 62 of the peripheral wall portion 61. Further, the cover 63 is provided with a mounting hole 67 in which a light emitting diode 68 for displaying the termite detection by the sensor unit 5 is arranged. The light-emitting diode 68 is illuminated in red simultaneously with the connection to the repeater 3, and is extinguished when the sensor unit 5 detects termites.

Further, the sensor unit 5 of the termite detection device 7
As shown in FIGS. 4 (a), (b), (c) and FIG. 5, a first member formed of a member including cellulose, for example, wood, is formed in a rectangular parallelepiped in a case 51 formed of a synthetic resin. Of the first attracting member 52
Detector 5 disposed on the upper part and formed of synthetic resin
3 and further disposed above the detection unit 53,
And a second attraction member 54 formed of the same material as the attraction member. The detection unit 5
On both sides of the third and second attracting members 54, a first substrate 55 on which the electric circuit shown in FIG. 7 is wired and a second substrate 56 on which the electric circuit shown in FIG. 8 is wired are fixed by screws. Is what it is. Further, a cutout 54b having a predetermined width is formed in the second attracting member 54 so that the foot of the electric component 56b wired to the substrates 55 and 56 projects.

The upper part of the second attracting member 54 is
The first attraction member 52, the detection unit 53 and the second attraction member 54, which are held in contact with a holding frame 57 formed above the inside of the case 51, are held by the holding frame. The upper and lower dimensions are regulated by 57 so that the end of the first attracting member 52 projects from the lower opening 58 of the case 51 by a predetermined value D (about 5 mm in this embodiment). ing. The portion protruding from the case 51 is a portion embedded in the soil of the sensor unit 5. The space between the lower opening 58 of the case 51 and the first attracting member 52 is sealed by a sealing member 59 such as a resin adhesive or silicon. The first attracting member 52 further has a hole 52b into which the stake 12 (shown in FIG. 6) for fixing the sensor unit 5 is inserted.

The first attracting member 52 has a terminus attracting hole 52a penetrating in a vertical direction, and the detecting portion 53 has a first hole communicating with the upper end of the attracting hole 52a. A (vertical hole) 53a and a second hole (horizontal hole) 53b perpendicular to the vertical hole 53a are formed. In this embodiment, one of the substrates 55 is provided in the horizontal hole 53b.
The transmitting element 20 extending from the other end and the receiving element 21 extending from the other substrate 56 are inserted from both ends, and the vertical hole 53 is inserted.
a is sandwiched between them.

The sensor unit 5 of the termite detection device 7 having the above configuration
In the above, the termite is inserted into the attraction hole 5 of the first attraction member 52.
When moving from 2a to the second attracting member 54, the vertical hole 5
3a, and cuts off the output wave transmitted from the transmitting element 20. As a result, since the output wave input to the receiving element 21 changes, the presence of termites can be detected. In addition, since the detection part 53 is made of a synthetic resin, when moving from the first attraction member 52 to the second attraction member 54, it is difficult for a portion other than the vertical hole 53a to pass therethrough. This increases the possibility of passing through 53a, and improves the termite detectability.

Further, the termite detection device 7 is installed under the floor of the house or around the house in the method shown in FIG. First, as shown in FIG.
The stake 12 is cut into a predetermined length, and the stake 12 is inserted into a hole 52 b formed on the bottom surface of the first attracting member 52.

Next, as shown in (b), the sensor section 5 to which the pile 12 is mounted is embedded at a predetermined depth (about 5 mm in this embodiment) from the soil surface 4 so as to bury the sensor section 5 under the floor. And the sensor unit 5 as shown in FIG.
Sow quotes around. In addition, in this embodiment, what was used was a chip obtained by cutting wood.
Any substance that emits the odor of the termites, for example, the odor of cellulose may be used.

Then, as shown in (d), the sensor part 5 is covered with the peripheral wall part 61 of the case 6 and is fixed to the ground by fixing bolts 13. Further, as shown in (e), a cable passage hole 66 formed in the upper end edge portion of the peripheral wall portion 61.

This is a jig for attaching the connection cable 9 to the cable passage hole 66.

Next, as shown in (f), the light emitting diode 68 is mounted in the mounting hole 67 formed in the cover 63, and finally the cover 63 is fitted into the peripheral wall 61 to mount the termite detecting device 7 thereon. Is to be completed.

Further, as shown in FIG. 1, the termite detecting devices 7 installed in the above-described manner are connected to the repeater 3 fixed at a predetermined position below the floor with screws or the like, as shown in FIG. Connected. The repeater 3 is further connected to the alarm device 2 via a connection cable 8. Then, the power adapter 10 connects the alarm device 2 and a household power outlet to complete the installation of the termite alarm device 1.

In the termite alarm device 1 installed as described above, the electric circuit wired to one substrate 55 of the sensor unit 5 of the termite detection device 7 is as shown in FIG. A power supply voltage of 12 V is supplied to the circuit from the alarm device 2 via the connection cable 8, the repeater 3, and the connection cable 9, and further via an electric circuit arranged on the other substrate 56 shown in FIG. An output wave (in this embodiment, infrared light) is output from the transmitting element 20 extending from one side of the horizontal hole 53b. In addition, the light emitting element 20 includes:
In this embodiment, an infrared light emitting diode (for example, TLN-103) is used.

The output wave of the infrared light emitting diode 20 is received by the receiving element 21 arranged on the opposite side of the horizontal hole 53b. As the receiving element 21, a phototransistor (for example, TPS-612) is used. FIG.
In the electric circuit wired to the substrate 56 on the other side, the collector side of the phototransistor 21 is input to a NOR GATE IC101.
As the NOR gate IC, for example, 14002 is used.

When no termite is present, the gate of the phototransistor 21 is always in a state of receiving light.
Since 1 is in a conductive state, the collector voltage of the phototransistor 21 becomes L, and therefore, the input side of the NOR gate IC 101 becomes L, so that the output side is usually H. When the output of the NOR gate IC 101 becomes H, the transistor 102 is turned on, and the red light emitting diode 68 is turned on.
The light emitting diode 68 is F336HD. Further, an RN1007 is used for a portion of the circuit included in the transistor 102, which is surrounded by a dashed-dotted line.

In the above-mentioned state, if termites enter the vertical hole 53a and the output wave of the light emitting diode 20 is cut off, the base input of the phototransistor 21 opposite to the light emitting diode 20 is lost. Then, the conduction of the phototransistor 21 is released, and a voltage is generated on the collector side of the phototransistor 21. Accordingly, at least one terminal on the input side of the NOR gate IC 101 becomes H, and the output signal of the NOR gate IC 101 changes from H to L.

As a result, the base voltage of the transistor C102 also changes from H to L, and the conduction of the transistor 102 is cut off, so that the red light emitting diode 68 is turned off. This makes it possible to specify the position of the termite detection device 7 where the termites have occurred.

Since the gate voltage of the transistor 103 also becomes L, the conduction of the transistor 103 is released and the collector terminal changes from L to H. Then, the phototransistor (for example, TLP521) 104 becomes conductive, and the voltage of the sensor signal line S1 of the connection cable 9 changes from H to L. As a result, the detection of termite is transmitted by the output signal from the termite detection device 7 on the sensor signal line S1 changing from H to L.

Signals (H → L) from the sensor unit 5 of the termite detection device 7 arranged under the floor are sent to the repeater 3 via the sensor signal lines S1 (S11, S12, S13, S14) of the connection cable 9. Sent. The electric circuit in the repeater 3 is shown in FIGS. 9 and 10, and for convenience of the drawing, the connector P3
ＰP6.

First, in FIG. 9, the sensor signal line S1
When at least one of (S11, S12, S13, S14) changes from H to L, the phototransistor 105 at a position corresponding to the changed signal line becomes conductive.

Thus, the phototransistor 105
Changes from H to L, so that the output of the first Schmitt trigger IC 106a is H, and
The output side of the Schmitt trigger IC 106b becomes L. As a result, at least one of the terminals of the connectors P3 to P6 changes from H to L by termite detection. Incidentally, for example, 14584 is used as the Schmitt trigger IC.

In FIG. 10, the connectors P3 and P4 are connected to input terminals B1 and B2 of a monostable multivibrator IC 107, and the connectors P5 and P6 are input terminals B1 and B of a monostable multivibrator IC 108.
2 is connected. As a result, when at least one of the voltages at the terminals P3 to P6 changes from H to L, an output signal having a pulse width set by the CR circuit 134 is output from the output terminals Q1 and Q2 corresponding to the input terminals B1 and B2. You.
This signal is output to the input terminal of the OR (OR) IC 109. As the OR IC 109, for example, 1407
2 are used.

Thus, one of the termite detection devices 7
More specifically, when a termite enters one of the vertical holes 53a of the sensor unit 5, one of the signals on the input side of the OR IC 109 changes from L to H, and the OR I
The output side of C109 changes from L to H. As a result, the transistor 110 conducts, and the voltage of the sensor signal line S of the connection cable 8 changes from H to L.

As shown in FIG. 1 and FIG. 2, the alarm device 2 outputs a visual alarm section comprising a number display section 40 for displaying the number of termites and a lead lamp section 41, and a sound for warning the detection of termites. A circuit having an audio alarm unit including a speaker 132 and controlling them is shown in FIGS. Note that the electric circuits of the alarm device 2 shown in FIGS. 11 to 16 also have connectors P7, P8, P9, P
10, P11 is used for division.

The phototransistor 111 connected from the repeater 3 by the sensor signal line S of the connection cable 8
Is turned on when the voltage of the sensor signal line S changes from H to L. Thus, the output side of the circuit 135 in which three Schmitt trigger ICs are connected in series is
The voltage on the collector side of the transistor 111 is changed from H to L
Changes from L to H. This output signal H is output on the one hand to the audio control circuit shown in FIG. 14 via the connector P11 and to the circuit shown in FIG. 11 via the connectors P7 and P8.

In FIG. 12, reference numeral 112 denotes a reset switch. When the reset switch 112 is turned on, the output side of the Schmitt trigger IC 112 (14584) changes from L to H, and the signal changed from L to H is
Counter IC 139 (FIG. 13), IC 124 (FIG. 15) via flip-flop IC 113, connector P9,
And an audio output circuit (FIG. 16).

In FIG. 12, a signal H generated on the collector side of the transistor 111 is input to the clock terminal (Ck) of the flip-flop IC 113 via the connector P8. Detecting the rising of the signal on the collector side from L to H,
The output of the output terminal Q of the flop IC 113 changes from L to H, and the output of the output terminal Q changes from H to L.

Normally, when termites are not detected, the output of the output terminal Q bar is H, so that the transistor 115
Is turned on and the green light emitting diode (VRPG5645) 1
37 lights up. However, when termites are detected and the clock terminal (Ck) changes from L to H, the output of the output terminal Q changes to H and the transistor 114 conducts,
Since the red light emitting diode 136 emits light and the output of the Q bar becomes L at the same time, the green light emitting diode 137 is turned off.

Accordingly, the green light emitting diode 137 constituting the lead lamp section 41 is detected by the termite detection.
Is turned off, and instead, the red light emitting diode 136 (VRPG5645) which also forms the lead lamp section 41 is turned on, so that the detection of termites can be displayed in the lead lamp section 41 as well.

In FIG. 13, the output of the connector P7, which changes from L to H when a termite is detected, is input to an AND gate IC (eg, 14081) 116. The output of the AND gate 138 and the output of the Schmitt trigger IC 117 are input to another input side of the AND gate IC 116. Normally, the output of this Schmitt trigger IC 117 is a counter IC
139 (for example, 14518) becomes L only when all the outputs become H.

When the signal from the connector P7 changes to H, the output of the AND gate IC 116 changes from L to H, and the counter IC 139 counts the number of changes from L to H. It is. This counted number is a 7-segment decoder (eg,
5022) is output to a numeral display circuit composed of 118 and 119 and 7-segment display (NKG261PB) 120 and 121, and the number of termites detected is displayed on the numeral display section 40. When the number of termites detected exceeds 99, the output of the Schmitt trigger IC 117 becomes L
Therefore, the output side of the AND gate 116 is always L
And the counting by the counter IC 139 is stopped.

FIGS. 14 to 16 show circuits of the audio section. First, in FIG. 14, a signal detecting termite is input from the circuit shown in FIG. 11 to the base terminal of the transistor 122 via the connector P11, and the base terminal of the transistor 122 becomes H.

As a result, the transistor 122 is turned on, and the base voltage of the transistor 123 is dropped by the turning on of the transistor 122. The transistor 123 is turned on to output the output voltage Vcc. This output voltage Vcc is supplied to each unit in FIGS. 15 and 16, and the audio unit starts operating. From the above, the audio unit starts operating in response to a signal that detects termites.

In FIG. 15, when the output voltage Vcc is supplied, the customer IC 124 starts operating,
A predetermined clock is output to the first counter IC 126. As a result, the first counter IC 126 outputs a binary number to the ROM 127, and the second counter IC 125 operates to output the upper 3 bits when the lower 11 bits are exceeded, and outputs a total of 14-bit output signals to the ROM 127. Output to The ROM 127 is, for example, a UV-EPROM 2
7C256, the programmed digital signal is
Output according to a 4-bit binary number. Then, the digital signal serving as the audio signal output from the ROM 127 is converted into an analog signal by the D / A converter 128,
Further, the custom IC 1 shown in FIG.
29 and is converted into a predetermined audio signal.

The audio signal is input to an audio power amplifier (for example, TA7368P) 131 and amplified, and a pair of N-channel power MOSFET 1
The signal is output to the speaker 132 via the switch 33.
As a result, when termites are detected, the ROM
The sound of the content stored in the speaker 127, for example, "A termite has occurred" can be played from the speaker.

On the other hand, a reset signal (RST) generated by pressing the reset switch 112 is supplied to the counter I via the IC 112 shown in FIG.
C125, 126 are input to the counter ICs 125, 1
26 is returned to the initial value. On the other hand, the reset signal is input to the base terminal of the transistor 130 shown in FIG.

As a result, since the base voltage of the transistor 130 increases from L to H,
Is released, and the collector voltage of the transistor 130 becomes L. As a result, the audio power amplifier I
Since the gate voltage of the N-channel power MOSFET 133 arranged between the C 131 and the speaker 132 becomes L and the conduction is cut off, the sound flowing from the speaker 132 is stopped.

With the above configuration, when each sensor unit 5 detects the invasion of termites, first, the light emitting diode 68 mounted on the case 6 of the termite detection device 7 is turned off, and the lead lamp unit 41 of the alarm device 2 is turned off. Changes from green to red. Further, the number of signals that have detected the invasion of the termites is displayed on the display unit 40.
It flows from 32 and informs the residents of the occurrence of termites. When the resident recognizes the occurrence of termites, the resident can reset the alarm by pressing the reset switch 112.

In the above embodiment, the detecting unit 53 that transmits infrared rays is used as the transmitting element 20.
A device that generates visible light, radio waves , and sound waves may be used, and the receiving device 21 corresponding to the transmitting device 20 may be used. In other words, it is only necessary to have a transmitting source for transmitting a predetermined output and a receiving unit for receiving the output, and to detect a change in the receiving unit caused by termites blocking what is generated from the generating source. Things. Further, like a sonar, an output wave may be generated at a constant interval from a transmission source, and a reflected wave of the output wave may be received by a receiving unit to detect a change in a emitted wave due to invasion of a termite or the like. Things.

In the above embodiment, the attraction member is disclosed as being made of wood such as pine containing cellulose, but may be made of hardened pulp, or may be made of a substance having a smell preferred by termites. It may be formed. Further, the attracting member has a humidity that termites prefer.

A transmitting device for transmitting sound waves in a frequency band preferred by termites may be attached to the attracting member, and the transmitting device itself may be used as the attracting means.
