2. Description of the Related Art Conventionally, detection devices for detecting, for example, floods and forest fires in rivers are generally provided at various places in a river embankment or in a mountain forest. It is configured to detect the water level and the temperature of the mountain and transmit the detection signal by radio or the like, and receive these signals at the management center etc. and collectively collect the water level and the temperature of the mountain I manage it. In such a detection device, a solar cell type power supply device is generally used as a power supply device. Here, according to the solar cell type power supply device, electric charge is generated in the solar cell when sunlight enters the light receiving panel of the solar cell, and the electric charge is stored in the storage battery, thereby charging the storage battery. It is. Then, power is supplied to various devices to be supplied with power by discharging the storage battery.

[0003]

By the way, in such a solar battery type power supply device, the storage battery is charged only when a certain amount of light enters the light receiving panel of the solar battery. Charging efficiency is low. Therefore, in rainy or cloudy weather, the storage battery cannot be sufficiently charged. For this reason, in order to increase the amount of sunlight incident on the light receiving panel of the solar cell as much as possible, the light receiving panel of the solar cell is installed facing upward and in the northern hemisphere with a slight inclination to the south.

However, in such a configuration, since the charging efficiency for the storage battery is low, it can be used only as an auxiliary power source when continuous power supply is required, for example. Is required. It is difficult to use this rechargeable battery for a long period of time, and the rechargeable battery is periodically replaced or additionally charged, and furthermore, the light receiving of the solar battery of the solar battery type power supply device is performed. It is necessary to clean the panel. For example, in the case of a detection device installed in a remote place or in a mountain, maintenance costs increase.

[0005] Such a problem exists not only in the above-mentioned river water level sensor and forest fire sensor, but also in a signal transmission device for transmitting various signals such as an earthquake sensor.

According to the above configuration, when sunlight enters the light receiving panel of the solar cell through the window of the main body, electric charge is generated in the solar cell, and the electric charge is charged in the electric double layer capacitor. Therefore, as compared with conventional storage batteries and other charging batteries, the light-receiving panel of the solar cell is disposed almost vertically, and furthermore, in rainy weather, cloudy weather, and shade.
Even when the amount of light incident on the light receiving panel is reduced, the electric double layer capacitor can be sufficiently charged.

[0010] If the window of the main body for guiding sunlight to the light receiving panel of the solar cell is arranged substantially vertically, accumulation of dust and adhesion of dirt on the outer surface of the window is reduced, so that electric power is reduced. Combined with the long service life of the double-layer capacitor of 20 years or more, a solar cell type power supply device which is almost maintenance free and has a long service life can be obtained. When the outer surface of the window is water-repellent, the accumulation of dust and the adhesion of dirt on the outer surface of the window are further reduced.

The illuminance switch is turned on, and the street light and the like are turned on. As a result, power saving can be realized with respect to the limited electric capacity stored in the electric double layer capacitor. When the illuminance switch determines the surrounding brightness based on the voltage generated in the solar battery, the surrounding brightness can be detected by using the solar battery. It is possible to reduce the cost and reduce the cost with a simple configuration. When the electric double-layer capacitor has a sufficient charge capacity to continuously supply power from the power supply take-out section, continuous operation of various devices connected to the power supply take-out section is performed by the charge capacity of the electric double-layer capacitor.

Shows an embodiment of a solar cell type power supply device of the present invention. 2 and 3, a solar cell type power supply 30
Is composed of a box-shaped main body 311 and a power supply circuit 320 disposed in the main body 311.

The main body 311 is provided with a waterproof structure so that raindrops do not enter the inside, and one side thereof (in the illustrated case,
A translucent window portion 312 is provided on a substantially vertical side surface 311a (front side).
It has. The window 312 is made of a light-transmitting material, preferably a light-transmitting material having weather resistance, and is attached to the window 312 in a liquid-tight manner. Thereby, the internal space of the main body 311 is hermetically sealed.
Further, the window 312 is preferably water-repellent on its outer surface. The main body 311 is provided with a mounting portion 313 projecting from both sides from the side opposite to the window portion 312, and the mounting portion 313 is fixed and held by being attached to, for example, a pillar by screwing or the like. You.

The power supply circuit 320 is described in, for example,
This is a power supply circuit using a solar cell disclosed in Japanese Patent No. 64859, and is configured as shown in FIG.
In FIG. 4, a power supply circuit 320 includes a solar cell 321 and an electric double layer capacitor 3 charged by the solar cell 321.
22, an illuminance switch 323, a constant voltage control circuit 324, and a power supply extracting unit 325. The electric double layer capacitor 322, the illuminance switch 323, and the constant voltage control circuit 324 are connected to a diode 32 for preventing backflow, which will be described later.
6. The charging voltage control circuit 327 is mounted on a circuit board 320a provided in the main body 311.

The solar cell 321 has a well-known structure, and generates electric power when light such as sunlight or illumination light enters the light receiving panel 321a as shown in FIG. As shown in FIGS. 2 and 3, the solar cell 321 is disposed substantially vertically along the inside of the window 312 of the main body 311 with the light receiving panel 321a facing outward.
This solar cell 321 is preferably connected to the signal transmission device 11.
It is desirable to dispose the light receiving panel upward at the top of the main body.

The electric double layer capacitor 322 is constituted by, for example, contacting two different phases of activated carbon and an organic solvent, and is capable of accumulating electrification in the same manner as a capacitor without the transfer of electrons accompanying a chemical reaction. Is charged. Therefore, the electric double layer capacitor 322 can be charged even with a small current, and
One light-receiving panel 321a is disposed substantially vertically, and is charged by the solar cell 321 even when the sunlight such as rainy weather, cloudy weather, or shade is weak and the incident solar energy is relatively low. Therefore, the electric double layer capacitor 322 is charged during the daytime regardless of the magnitude of the output current of the solar cell regardless of weather such as fine weather, rainy weather, and cloudy weather.

In the case shown in the figure, between the solar cell 321 and the electric double layer capacitor 322, a diode 326 for preventing backflow and the solar cell 321 are connected to the electric double layer capacitor 3.
Charge voltage control circuit 3 for controlling the charge voltage to 22
27 are connected. This charging voltage control circuit 327
When the charging voltage from the solar cell 321 to the electric double layer capacitor 322 reaches the overcharge voltage of the electric double layer capacitor 322, the output of the solar cell 321 is cut off to prevent the electric double layer capacitor 322 from being destroyed.

The illuminance switch 323 has a switch circuit connected between the electric double layer capacitor 322 and the constant voltage control circuit 324. In this case, as shown in FIG. The switch circuit is turned on when the power generation voltage of the solar cell 321 is equal to or lower than a predetermined level, and is turned off when the generated voltage exceeds the predetermined level.

The constant voltage control circuit 324 has a known configuration, and holds the output voltage from the electric double layer capacitor 322 at a predetermined voltage. The power take-out section 32
5 is provided so as to be exposed on the upper surface of the main body 311 as shown in FIGS.
The output voltage from the electric double layer capacitor 322 is applied via the.

Here, the above-described electric double layer capacitor 3
The capacity of 22 is selected as a capacity sufficient to drive various devices connected to the power supply extraction unit 325. For example,
When various devices connected to the power supply take-out unit 325 are continuously driven, the capacity of the electric double layer capacitor 322 is selected to a capacity corresponding thereto. In addition, the solar cell 321
Is selected to be a sufficient capacity for charging the electric double layer capacitor 322 necessary.

Next, the management center 20 receives a radio wave from each of the signal transmission devices 11 installed at various locations, and detects a fire on the basis of a detection signal received and demodulated by the receiving unit 21. And a management unit 22 for performing management.

The receiving section 21 receives radio waves from each of the signal transmission devices 11, extracts an identification signal and an identification signal by demodulation, forms a set of the identification signal and the identification signal, and sends the set to the management section 22.
Based on the identification signal and the detection signal from the reception unit 21, the management unit 22 determines whether or not there is a wildfire, for example, at the position of each signal transmission device 10 on the map displayed on the screen based on the detection signal. , For example, a green display when there is no wildfire, a red display when a wildfire has occurred, and a warning sound or warning display when a wildfire has occurred. Have been.

The forest fire detection device 10 according to the present invention is configured as described above and operates as follows. First, in the daytime, sunlight enters the light receiving panel 321 a of the solar cell 321 through the window 312 of the main body 311, power is generated by the solar cell 321, and current flows through the backflow prevention diode 326 and the charging voltage control circuit 327. Through the electric double layer capacitor 322. Thereby, the electric double layer capacitor 322 is charged.

At this time, since the solar cells 321 are arranged almost vertically, the amount of light incident on the light receiving panel 321a is relatively low, or the solar energy is relatively low due to rain, cloudy or shade. Even in this case, the electric charge generated in the solar cell 321 is
, The charging efficiency of the electric double layer capacitor 322 is high. Therefore, even in rainy weather, cloudy weather, or shade, sufficient charge in the daytime can be obtained by the electric double layer capacitor 3.
22. At this time, since a relatively high voltage is applied to the illuminance switch 323 from the solar cell 321, the switch circuit of the illuminance switch 323 is off, and power is supplied from the electric double layer capacitor 322 via the constant voltage control circuit 23. Is not done.

On the other hand, since no sunlight or the like enters the solar cell 321 at night, power is not generated by the solar cell 321. At this time, even if a current flows from the electric double layer capacitor 322 to the solar cell 321, the current is blocked by the backflow prevention diode 25. On the other hand, illuminance switch 3
In the power supply unit 23, a voltage lower than a predetermined level is applied from the solar cell 321 and the switch circuit is turned on, and the power supply unit 325 from the electric double layer capacitor 322 via the illuminance switch 323 and further via the constant voltage control circuit 324. Output to the outside.

As described above, the discharge voltage applied from the power supply circuit 320 to the power supply take-out section 325 is maintained at a predetermined voltage by the constant voltage control circuit 324. The amplifier 13 and the transmission unit 14 operate in a stable state.

Normally, that is, when a forest fire has not occurred, the signal transmission device 11 causes the temperature sensor 12 to output an L level detection signal. Therefore, the transmission unit 14 modulates the identification signal and the L-level detection signal and transmits the modulated signal as radio waves. In response, the reception unit 21 of the management center 20 receives and demodulates the identification signal and the L-level detection signal from the transmission unit 14 of the signal transmission device 11, and sends out the demodulated signal to the management unit 22. Accordingly, the management unit 22 determines which signal transmission device 11 is the detection signal from the identification signal, and determines that the detection signal from the signal transmission device 11 is at the L level, that is, that no forest fire has occurred. I do. In this case, the display of the presence / absence of a forest fire on the screen of the management unit 22 remains green.

Here, when a forest fire occurs near a certain signal transmission device 11, the temperature in the vicinity increases. Then, the signal transmission device 11 outputs an H-level detection signal when the temperature sensor 12 detects a temperature equal to or higher than a predetermined temperature. As a result, the transmission unit 14 modulates the identification signal and the H-level detection signal and transmits them as radio waves. In response to this, the reception unit 21 of the management center 20 receives and discriminates the identification signal and the H-level detection signal from the transmission unit 14 of the signal transmission device 11, and sends the demodulated signal to the management unit 22.

Accordingly, the management unit 22 determines which signal transmission device 11 is the detection signal from the identification signal, and determines that the detection signal from the signal transmission device 11 is at the H level.
That is, it is determined that a forest fire has occurred. Then, the management unit 22 changes the position of the signal transmission device 11 on the map displayed on the screen to a red display indicating that a forest fire has occurred, and performs a warning sound or a warning display by a warning device (not shown). . Thereby, the staff of the management center 20 can know the occurrence of the forest fire by the warning sound or the warning display, and easily grasp the location of the occurrence of the forest fire by looking at the display on the screen of the management unit 22. Can be. Note that the management unit 22 may be configured to transmit or transmit a signal indicating that a forest fire has occurred to another department, for example, a fire department.

As described above, according to the forest fire detection device 10 according to the embodiment of the present invention, the generated forest fire is detected by the temperature sensor 12 of the signal transmission device 11 installed in each place, and the detected signal is sent to the management center 20. By transmitting the information by radio waves or the like, it is possible to reliably and quickly find out. At that time, since the solar battery type power supply device 30 is composed of the solar battery 321 and the electric double layer capacitor 322, the battery can be charged sufficiently even in rainy weather or in the shade as compared with the conventional battery for charging. it can. Further, the main body 3 that guides sunlight to the light receiving panel 321a of the solar cell 321
The eleventh window 312 is disposed substantially vertically, and preferably, the outer surface of the window 312 is water-repellent, thereby preventing dust and the like from accumulating on the outer surface of the window 312 and adhering dirt. Therefore, cleaning of the outer surface of the window 312 is almost unnecessary. Therefore, coupled with the long life of the electric double layer capacitor 322, it is possible to obtain the solar cell type power supply device 30 which is almost maintenance free and has a long life.

Therefore, by using this solar cell type power supply device 30 in a place where there is no commercial power supply or in various places such as a mountain, an uninhabited island, etc. It is possible to drive a relay antenna of a telephone or a PHS. At that time, maintenance is almost unnecessary for the solar battery type power supply device 30, and maintenance and management become easy. In this case, the temperature sensor 12 is used as the detection sensor. However, the present invention is not limited to this, and another type of detection sensor, for example, a water level sensor can be provided near the embankment of the river. In the case of this water level sensor, the water level of the river can be detected by the water level sensor and transmitted to the remote management center 20. Thereby, the water level of the river can be managed collectively by the management center. Further, a security sensor in a so-called security system can be used as the detection sensor.

FIG. 5 shows an emergency warning device for nursing care to which a second embodiment of the signal transmission device according to the present invention is applied. In FIG. 5, the emergency care alarm device 40 is provided with an emergency switch 41 instead of the temperature sensor 12 in the forest fire detection device 10 of FIG. 1, except that an alarm device 42 is connected to the amplifier 13. Since the configuration is substantially the same as that of the wildfire detection device shown in FIG. 1, the same components are denoted by the same reference numerals and description thereof will be omitted.

Normally, that is, when there is no abnormality in the care recipient, the signal transmission device 11 outputs an L-level detection signal because the emergency switch 41 is not operated. Therefore, the transmission unit 14 modulates the identification signal and the L-level detection signal and transmits the modulated signal as radio waves. In response, the receiving unit 21 of the management center 20 sends the signal transmission device 1
The receiving unit 14 receives and discriminates the identification signal and the L-level detection signal from the first transmission unit 14 and transmits the demodulated signal to the management unit 22. Thereby, the management unit 22 determines which signal transmission device 1
It is determined whether the detection signal is from the signal transmission device 1 or not, and the detection signal from the signal transmission device 11 is at the L level, that is, it is determined that no abnormality has occurred in the care recipient. In this case, the management unit 2
The display of the presence / absence of the abnormality on the screen 2 remains green.

Here, when an abnormality occurs in the care receiver, the care receiver operates the emergency switch 41 of the signal transmission device 11, whereby the alarm signal from the emergency switch 41 is amplified by the amplifier 13, and It is input to the transmission unit 14 and the alarm device 42. Thereby, the alarm device 42
Performs a warning sound or a warning display, and the transmitting unit 14 modulates the identification signal and the H-level warning signal and transmits them as radio waves. In response, the receiving unit 21 of the management center 20 receives and demodulates the identification signal and the H-level detection signal from the transmitting unit 14 of the signal transmission device 11, and
To send to.

Therefore, the management unit 22 determines which signal transmission device 11 is the detection signal from the identification signal, and determines that the detection signal from the signal transmission device 11 is at the H level.
That is, it is determined that the care target person has an abnormality.
Then, the management unit 22 changes the position of the signal transmission device 11 on the map displayed on the screen to a red display indicating that a care recipient abnormality has occurred, and displays a warning sound or a warning display by a warning device (not shown). Perform Thus, the staff of the management center 20 can know the occurrence of the abnormality of the care recipient by the warning sound or the warning display, and can easily see the display of the location of the care recipient's home on the screen of the management unit 22. Can be grasped. Note that the management unit 22 may be configured to transmit or transmit a signal indicating a request for emergency dispatch of the care recipient to another department, for example, a hospital or a fire department.

Thus, according to the emergency warning device for nursing care 40 according to the embodiment of the present invention, the solar cell type power supply device 3
Since 0 is composed of the solar cell 321 and the electric double-layer capacitor 322, it is possible to perform sufficient charging even in rainy weather, cloudy weather, and shade as compared with a conventional charging battery. Therefore, since the life of the electric double layer capacitor 322 is long, it is possible to obtain the solar battery type power supply device 10 which is almost maintenance-free and has a long life. In particular, even if the care recipient's home is in a power outage or the like, the signal transmission device 11 can always be operated by the solar cell type power supply device 30. Can notify the care recipient of the occurrence of an abnormality, and even if the management center 20 cannot receive an alarm signal due to a failure of the transmission unit 14 or the management center 20 or the like, a warning sound or warning is given to the surroundings by the alarm device 42. The display can reliably inform the care recipient of the occurrence of an abnormality.

FIG. 6 shows a position information transmission apparatus to which a third embodiment of the signal transmission apparatus according to the present invention is applied.

Therefore, the same reference numerals are given to the same components, and the description thereof will be omitted.

In the position information transmission device 50 shown in FIG. 6, the signal transmission device 11 is carried by a dementia patient, for example.
The position information detection device 51 is configured to sequentially acquire position information by, for example, GPS and output the obtained information as a detection signal. The position information detecting device 51 is, for example, a PHS
