Description

  The present invention relates to a portable position information notification device that notifies position information of a device owner.

  Recently, various crime prevention devices have been considered to ensure the safety of children when they go to school, and the security buzzer has been distributed to children from schools as an easy one.

  By the way, recently, there is a service for distributing position information where a child exists to a home by communication means one by one, and a portable position information notification device possessed by children is attracting attention.

  This position information notification device uses, for example, a GPS (Galileo Positioning system) function to identify the position information of the device owner, and uses the communication means such as a mobile phone or a PHS (Personal Handyphone System) for the position information. Use RFID (Radio Frequency Identification) function to notify your home, etc., and install RFID readers at specific locations, such as school gates and school roads, and equipment owners pass through these points. In this way, the position is specified, and this position information is notified to the home or the like using the communication means of the RFID reader.

By the way, such a position information notification device is carried around and naturally has no power supply from the outside, so a power source is required in the device. Patent Document 1 discloses a battery that uses a rechargeable secondary battery or a primary battery such as a manganese dry battery or an alkaline dry battery as a power source for a portable device.

  However, when a primary battery, that is, a dry battery is used as a power source, there is an advantage that it generally has a higher energy density and lasts longer than a secondary battery, and can be used immediately after replacement even if the battery runs out. However, since the dry battery needs to be replaced every time the battery runs out, there arises a problem that the running cost increases.

  On the other hand, using a secondary battery as a power source does not require battery replacement, so the running cost is advantageous, but naturally the secondary battery cannot be used unless it is charged. The battery must be charged each time the battery becomes low. However, in general, nickel-metal hydride storage batteries and lithium ion secondary batteries cannot be rapidly charged and require 1 to 2 hours for charging. For this reason, it takes time to charge, and if it is found that the battery has run out just before going out, charging the power battery will not be in time for the scheduled time, and the device for crime prevention will not be carried. Usability is significantly reduced, such as having to give up.

  Therefore, it is conceivable to increase the capacity of the secondary battery mounted on the device and extend the usable time, but the battery becomes larger and the entire device is larger and heavier, which greatly increases portability. The problem of losing.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a position information notification device which is excellent in usability and can reduce the lining cost.

  The invention according to claim 1 is a position information notification device for notifying the position information of the device main body as the device main body moves to the outside from the wireless communication means, and is provided inside the device main body and is necessary for the operation of the device main body. It is characterized by having a rechargeable battery that can be rapidly charged with a current of 10 C or more, which is used as a power source for supplying a large amount of power.

  According to a second aspect of the present invention, in the first aspect, the apparatus main body includes a GPS receiving unit that receives a GPS signal, and notifies the positional information based on the GPS signal received by the GPS receiving unit. It is a feature.

  A third aspect of the invention is characterized in that, in the first aspect of the invention, the apparatus main body has a communication means using RFID, and the position information is notified by communication with the RFID reader by the communication means.

  According to a fourth aspect of the present invention, in the apparatus according to any one of the first to third aspects, the apparatus main body includes a charging unit, and the charging unit is electrically connectable to an external charging power source. It is characterized by charging a rechargeable battery.

  According to a fifth aspect of the present invention, in the apparatus according to any one of the first to third aspects, the apparatus main body has power generation means for generating electric power by converting kinetic energy corresponding to the movement of the apparatus main body into electric energy. In addition, the rechargeable battery is supplementarily charged with the electric power of the power generation means.

  A sixth aspect of the present invention is characterized in that, in any one of the first to third aspects, the device main body includes a battery remaining amount display means for displaying a remaining battery amount of the rechargeable battery.

  According to the present invention, it is possible to provide a position information notification device that is easy to use and can reduce running costs.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
FIG. 1 shows an external view of a position information notification device applied to a security device according to a first embodiment of the present invention.

  In FIG. 1, reference numeral 1 denotes a position information notification apparatus main body (hereinafter referred to as an apparatus main body). The apparatus main body 1 has a main body case 1a made of a flat rectangular parallelepiped. The main body case 1a has a size enough to fit in a pocket or the like.

  A rechargeable battery 2 is accommodated in a battery chamber (not shown) inside the main body case 1a. The rechargeable battery 2 can be taken in and out of the battery chamber. Details of the rechargeable battery 2 will be described later.

  On the upper surface of the main body case 1a, a switch 3 and a battery remaining amount display unit 4 are arranged. The switch 3 constitutes a power switch that supplies the power of the rechargeable battery 2 to the control unit 14 described later. The battery remaining amount display unit 4 displays the discharge state of the rechargeable battery 2. The light emitting body blinks when the remaining charge amount of the rechargeable battery 2 is a predetermined value or less, continues to be lit during charging, and charging is completed. Turns off. For example, an LED is used as the light emitter. In this case, for example, a blue LED may be turned on when the remaining charge amount is equal to or greater than a predetermined value, and a red LED may be turned on when the remaining battery amount falls below a predetermined value.

  An external AC power input terminal 5 is provided on the side surface of one end of the main body case 1a. An AC power source (commercial power source) described later is connected to the external AC power source input terminal 5 as an external charging power source.

  FIG. 2 shows a circuit configuration of the apparatus main body 1. In FIG. 2, the same parts as those in FIG.

  In FIG. 2, reference numeral 2 denotes a rechargeable battery. The rechargeable battery 2 is provided inside the main body case 1 a and is used as a power source necessary for the operation of the apparatus main body 1. As the rechargeable battery 2, a lithium ion secondary battery capable of rapid charging is used in the present embodiment. The lithium ion secondary battery includes a container made of an exterior member made of an aluminum laminate film, a nonaqueous electrolyte housed in the container, and a lithium cobalt oxide in a positive electrode current collector made of aluminum foil housed in the container. A positive electrode carrying a positive electrode layer containing as a positive electrode active substance; and a negative electrode carrying a negative electrode layer containing lithium titanium oxide as negative electrode active substance particles in a negative electrode current collector made of aluminum foil and housed in the container. It has the structure provided.

  Here, the lithium ion secondary battery will be described in more detail. Such a lithium ion secondary battery includes a negative electrode containing lithium titanium oxide as an active substance. As disclosed in Patent Document 2, the lithium titanium oxide which is an active substance is a material capable of inserting and extracting lithium, and insertion / extraction of lithium ions is performed in the vicinity of 1.4 V to 1.7 V / Li. . For this reason, even if this secondary battery is rapidly charged with a large current, safety can be secured without precipitation of lithium as compared with the case where a carbon material is used as a conventional negative electrode active substance. In addition, since expansion and contraction associated with insertion and extraction of lithium can be suppressed, structural destruction of the negative electrode active substance can be suppressed even when rapid charging with 20 C current is repeatedly performed. As a result, a long life can be maintained even when charging and discharging are repeated. Since the nominal capacity of the battery is about 2.4 V, it corresponds to two conventional nickel-metal hydride storage batteries or nickel cadmium storage batteries in series, so that a reduction in use of 50% can be achieved.

  Specifically, it was confirmed that the lithium ion secondary battery assembled by the following method is a fast charge secondary battery that can be charged to about 80% battery capacity by charging at 20 C for 3 minutes. ing. Here, “C” is a unit representing a charge / discharge rate, and a rate that can be calculated in one hour when a constant current charge from full discharge to full charge (or from full charge to full discharge) is calculated is expressed as 1C. In the case of 1/10 hour, it is expressed as 10C. Therefore, for example, 20C charging requires 20 times as much current as 1C charging.

<Production of negative electrode>
The active substance is lithium titanate (Li ₄ Ti ₅ O ₁₂ ) powder having an average particle diameter of 5 μm and a Li storage potential of 1.55 V (vs. Li / Li ⁺ ), and carbon having an average particle diameter of 0.4 μm as a conductive agent. The powder and polyvinylidene fluoride (PVdF) as a binder were blended in a weight ratio of 90: 7: 3, and these were dispersed in an n-methylpyrrolidone (NMP) solvent to prepare a slurry.

  In addition, the laser diffraction type particle size distribution measuring apparatus (Shimadzu Corporation model number SALD-300) was used for the measurement of the particle diameter of an active substance. First, about 0.1 g of a sample was put in a beaker or the like, and then a surfactant and 1 to 2 mL of distilled water were added and stirred sufficiently, and poured into a stirred water tank. The light intensity distribution was measured 64 times at intervals of 2 seconds, the particle size distribution data was analyzed, and the particle size (D50) having a cumulative frequency distribution of 50% was defined as the average particle size.

Next, an aluminum foil (purity: 99.99%) having a thickness of 10 μm was applied to the negative electrode current collector, dried, and then pressed to prepare a negative electrode having an electrode density of 2.4 g / cm ³ .

<Preparation of positive electrode>
Lithium cobalt oxide (LiCoO ₂ ) as an active substance, graphite powder as a conductive material, and polyvinylidene fluoride (PVdF) as a binder are blended in a weight ratio of 87: 8: 5, and these are mixed with n -A slurry was prepared by dispersing in a methylpyrrolidone (NMP) solvent. The slurry was applied to an aluminum foil (purity 99.99%) having a thickness of 15 μm, dried, and pressed to prepare a positive electrode having an electrode density of 3.5 g / cm ³ .

<Assembly of secondary battery>
As a forming material for the container (exterior member), an aluminum-containing laminate film having a thickness of 0.1 mm was prepared. The aluminum layer of this aluminum-containing laminate film had a thickness of about 0.03 mm. Polypropylene was used as the resin for reinforcing the aluminum layer. A container (exterior member) was obtained by laminating the laminate film by heat sealing.

  Next, a positive electrode terminal was electrically connected to the positive electrode, and a negative electrode terminal was electrically connected to the negative electrode. A separator made of a polyethylene porous film having a thickness of 12 μm was coated in close contact with the positive electrode. The positive electrode covered with the separator was overlapped with the negative electrode so as to face each other, and these were wound in a spiral shape to produce an electrode group. This electrode group was pressed into a flat shape. An electrode group formed into a flat shape was inserted into a container (exterior member).

LiBF ₄ , which is a lithium salt, is dissolved in an organic solvent in which ethylene carbonate (EC) and γ-butyllactone (GBL) are mixed at a volume ratio (EC: GBL) of 1: 2 to obtain a liquid. A non-aqueous electrolyte obtained by preparing a non-aqueous electrolyte was poured into the container and sealed by heat sealing of the aluminum laminate film opening with the positive and negative terminals exposed to the outside. Assembled.

  FIGS. 3A and 3B are external views of the lithium ion secondary battery assembled in this manner. For example, a rectangular battery body 211 having an outer diameter of 5.5 × 30 × 50 mm is shown in FIGS. The positive electrode terminal 212 and the negative electrode terminal 213 are led out from one end of the battery main body 211, respectively. Such a secondary battery has a full charge voltage of 2.8 V, a constant current constant voltage charge at 228 mA-2.8 V, and a capacity of about 450 mAh when discharged to 2.0 V with a 450 mA constant current discharge. is there. The secondary battery can be rapidly charged with a current of 10 C or more. Here, as described above, 1 C represents a current value that can be calculated in one hour when a constant current charge is performed from the discharge state to the charge, and corresponds to 450 mA in the above-described secondary battery. Therefore, being able to charge quickly with a current of 10 C or more means that it can be charged with a current (450 × 10) mA 10 times that of 1C. As a result, when a 4.5A-2.8V constant current / constant voltage charge (10C charge) is performed from a discharged state (discharged to 2.0V by 450 mA continuous discharge), 80% (360 mAh) or more within 5 minutes. In the case of 9A-2.8V constant current constant voltage charging (20C charging), 80% or more of capacity can be charged within 3 minutes. During this rapid charging, problems such as abnormal heat generation do not occur. That is, the secondary battery here can be rapidly charged, which is difficult with conventional nickel metal hydride storage batteries or lithium ion batteries.

  The rechargeable battery 2 is provided with a monitoring protection circuit 6 as monitoring protection means. The monitoring protection circuit 6 monitors the state of the rechargeable battery 2 and stops charging / discharging of the rechargeable battery 2 by driving a switch (not shown) according to the monitoring result. In this case, the monitoring protection circuit 6 monitors overcharge, overdischarge and overcurrent of the rechargeable battery 2. When the charging voltage of the rechargeable battery 2 is in a predetermined value range, charging / discharging of the rechargeable battery 2 is allowed. When the charging voltage of the rechargeable battery 2 exceeds a predetermined value, it is determined that the battery is overcharged and the switch (not shown) ) Is released to stop the charging of the rechargeable battery 2, and when the charging voltage of the rechargeable battery 2 falls below a predetermined value, it is determined that the battery is overdischarged and the switch (not shown) is opened to open the rechargeable battery 2. Stop the discharge. Further, when the discharge current of the rechargeable battery 2 or the charge current exceeds a predetermined value, it is determined as an overcurrent and the switch (not shown) is opened to stop the discharge of the rechargeable battery 2. This prevents the rechargeable battery 2 from being overcharged and generating gas due to the decomposition of the electrolyte, increasing the pressure inside the battery and preventing leakage, and the rechargeable battery 2 from being overdischarged. This prevents the battery performance from deteriorating. Such a monitoring protection circuit 6 is modularized and connected to the rechargeable battery 2. Note that the monitoring protection circuit 6 may monitor at least one of overcharge, overdischarge, and overcurrent of the rechargeable battery 2.

  A charge control unit 7 is connected to the rechargeable battery 2 as a charging means. The charging control unit 7 charges the rechargeable battery 2 and is connected to the external AC power input terminal 5 described above. In this case, the AC adapter 8 is electrically connected to the external AC power supply input terminal 5 as an external charging power supply. The AC adapter 8 has an AC / DC converter 9. The AC / DC converter 9 converts AC power of a 100 V AC power source (commercial power source) 10 into DC power, and this DC power is supplied to the charging control unit 7 via the external AC power source input terminal 5. 2 is supplied as charging power.

  A built-in power generation unit 11 is connected to the charge control unit 7 as power generation means. As shown in FIG. 4, the built-in power generation unit 11 includes a cylindrical member 111 made of an insulating material. The coil 112 is wound around the outer peripheral surface of the cylindrical member 111, and is permanent along the hollow portion of the coil 112. It has a power generation mechanism in which the magnet 113 is movably arranged. In this power generation mechanism, when the entire cylindrical member 111 is swung, the permanent magnet 113 reciprocates in the directions of the arrows a and b along the hollow portion of the coil 112, whereby the magnetic flux passing through the coil 112 changes, and the coil An electromotive force is generated at 112.

  The output of the built-in power generation unit 11 (electromotive force of the coil 112) is supplied to the charging control unit 7 as charging power for the rechargeable battery 2. In this case, the polarity of the electric power output from the built-in power generation unit 11 is reversed depending on the moving direction of the permanent magnet 113 that moves through the hollow portion of the coil 112, that is, the direction indicated by the arrow a or b. For this reason, the output power of the built-in power generation unit 11 is converted into DC power through the rectifier circuit 71 and supplied to the charge control unit 7. This rectifier circuit 71 uses what is integrated in the charging control unit 7.

  The amount of power generated by the built-in power generation unit 11 is not so large, and an amount sufficient to cover the power required by the entire apparatus main body 1 cannot be obtained, but the rechargeable battery 2 can be used little by little during use of the apparatus. Thus, there is an effect that it is possible to extend the use time until the rechargeable battery 2 runs out of battery.

  The built-in power generation unit 11 may be configured as shown in FIG. In this case, the power generation mechanism integrally has a rotating gear 122 on the central shaft 121 a of the fan-shaped rotating weight 121, and transmits the rotation of the rotating gear 122 to the rotor 124 via the speed increasing gear 123. The rotor 124 is composed of a high-performance permanent magnet. A stator 126 around which a coil 125 is wound is disposed around the rotor 124. In such a power generation mechanism, when the rotating weight 121 rotates in the direction of the arrow c in the figure, this rotation is transmitted to the rotor 124 via the rotating gear 122 and the speed increasing gear 123, and the rotor 124 rotates to rotate the stator 126. The passing magnetic flux changes, and an electromotive force is generated in the coil 125. Even with the configuration described above, the same effect as described in FIG. 4 can be obtained.

  Further, the built-in power generation unit 11 may be configured as shown in FIG. In this case, the power generation mechanism includes a cylindrical member 131 made of an insulating material, piezoelectric elements 132 and 133 are provided at both opening ends of the cylindrical member 131, and a moving member 134 is disposed in a hollow portion of the cylindrical member 131. Yes. In such a power generation mechanism, when the entire cylindrical member 131 is swung, the moving member 134 reciprocates along the hollow portion of the cylindrical member 131 in the directions indicated by the arrows d and e and collides with the piezoelectric elements 132 and 133. The piezoelectric elements 132 and 133 are deformed by this collision, thereby generating an electromotive force. Even with the configuration described above, the same effect as described in FIG. 4 can be obtained.

  Such a built-in power generation unit 11 generates electric power by converting kinetic energy corresponding to the movement of the apparatus main body 1 into electric energy, and even if it is provided in the apparatus main body 1, both size and weight are problematic. As long as it is not necessary, a configuration other than the configuration described above can be applied.

  Returning to FIG. 2, the control unit 14 is connected to the rechargeable battery 2 via the switch 3. The control unit 14 controls the entire apparatus main body 1, and is connected to the battery remaining amount display unit 4, the GPS reception unit 15, the alarm generation unit 16, and the communication unit 17 as a communication unit. The GPS receiver 15 receives a GPS signal from a GPS satellite and outputs position information of the device main body 1 (device owner). The alarm generating unit 16 is composed of, for example, a security buzzer, and generates an alarm sound and outputs alarm operation information by an emergency operation of the device owner. The communication unit 17 includes a communication unit such as a mobile phone or a PHS, and transmits notification information generated by the control unit 14 to the monitoring center 18. The monitoring center 18 distributes position information to the home of the device owner by the notification information, and requests an emergency response from various directions by the emergency notification information. In addition, since the communication means of a mobile telephone or PHS is a well-known thing, detailed description here is abbreviate | omitted.

  The control unit 14 includes a notification information generation unit 141 and a battery remaining amount monitoring unit 142. The notification information generation unit 141 generates notification information based on the position information input from the GPS receiver 15 and the alarm operation information output from the alarm generator 16. In this case, the notification information generation unit 141 generates notification information, for example, at regular intervals based on the position information input from the GPS reception unit 15 and outputs the notification information to the communication unit 17, and the alarm operation information from the alarm generation unit 16. Is input, emergency notification information is immediately generated using the position information from the GPS receiver 15 at this time, and is output to the communication unit 17. The battery remaining amount monitoring means 142 monitors the discharge state of the rechargeable battery 2, and when the remaining charge amount falls below a predetermined value, the light emitter of the remaining battery amount display unit 4 blinks and continues to be lit during charging. Goes off.

  Next, the operation of the embodiment configured as described above will be described.

  First, the device owner connects the AC adapter 8 to the external AC power input terminal 5 of the device body 1 when the light emitter of the battery remaining amount display unit 4 is blinking. Then, DC power is supplied from the AC power source 10 to the charging control unit 7 via the AC / DC converter 9, and the rechargeable battery 2 is charged to full charge. Thereafter, it is confirmed that the rechargeable battery 2 is fully charged because the light emitter of the battery remaining amount display unit 4 is turned off. When the full charge of the rechargeable battery 2 is confirmed, the AC adapter 8 is disconnected from the external AC power input terminal 5.

  In this state, the apparatus main body 1 is carried in a pocket or the like with the switch 3 turned on. The GPS receiver 15 receives a GPS signal from a GPS satellite and outputs position information of the device main body 1 (device owner). The position information from the GPS receiving unit 15 is input to the control unit 14, and notification information is generated and output to the communication unit 17 by the notification information generation unit 141 of the control unit 14 at regular intervals, for example. Accordingly, notification information is transmitted from the communication unit 17 to the monitoring center 18, and the position information is notified from the monitoring center 18 to the home of the device owner.

  On the other hand, when the alarm operation information is output together with the alarm sound from the alarm generation unit 16 by the emergency operation of the device owner, the notification information generating unit 141 of the control unit 14 obtains the position information from the GPS reception unit 15 at this time. The emergency notification information is immediately generated and output to the communication unit 17. Thereby, the emergency notification information is notified from the communication unit 17 to the monitoring center 18 together with the position information, and the monitoring center 18 requests an emergency response to each area.

  The remaining battery level monitoring unit 142 monitors the remaining battery level of the rechargeable battery 2. When the remaining battery level drops below a predetermined value, the light emitter of the remaining battery level display unit 4 is blinked. When the device owner confirms the display of the battery remaining amount display unit 4, for example, when he / she goes home, the AC adapter 8 is inserted into the external AC power input terminal 5 to charge the rechargeable battery 2 to full charge again. Prepare for the next use.

  Therefore, in this case, the rechargeable battery 2 is used as the power source of the position information notification device, and the AC adapter 8 can be connected to the apparatus main body 1 so that the rechargeable battery 2 is fully charged. Enabled use. Further, as the rechargeable battery 2 to be incorporated, a lithium ion secondary battery that can be rapidly charged with a current of 10 C or more is used. Thereby, since the rechargeable battery 2 can be rapidly charged for a very short time of about several minutes, for example, when a battery exhaustion is found just before going out, a case where a conventional normal secondary battery is mounted, When this was charged, it took a long time to charge, and there were cases where it was not in time for the scheduled time. Even in such a case, if the AC adapter 8 was used, an AC power source (commercial power source) was used. ) Can be quickly charged in a short time, so that the inconvenience of giving up carrying can be avoided and the usability as a position information notification device can be improved. Furthermore, since the rechargeable battery 2 is used, it is not necessary to replace the battery when the battery runs out, so that the running cost can be reduced.

  Further, since the rechargeable battery 2 can be frequently charged, it is possible to use the rechargeable battery 2 having a small battery capacity, and it is possible to reduce the cost and reduce the size of the portable device. These can be realized by using the rechargeable battery 2 capable of rapid charging.

  Further, the built-in power generation unit 11 is arranged inside the apparatus main body 1 by utilizing the usage characteristics of the position information notification apparatus, and when the apparatus owner moves, the apparatus main body 1 is vibrated so that the built-in power generation Electric power is generated in the part 11 and the rechargeable battery 2 is supplementarily charged with the generated power. Thereby, since the rechargeable battery 2 can be supplementarily charged little by little during use of the apparatus, the usable time until the rechargeable battery 2 runs out can be extended.

  Furthermore, the apparatus main body 1 is provided with a battery remaining amount display unit 4 for displaying the discharge state of the rechargeable battery 2, and the discharge state of the rechargeable battery 2 can be confirmed at a glance. It can be avoided in advance that the remaining battery level becomes zero and the device becomes unusable.

In this case, the apparatus main body 1 has the following configuration instead of the GPS receiving unit 15, the notification information generating unit 141, and the communication unit 17 described above.

  The control unit 14 includes personal information storage means 143 that stores personal information for identifying the device owner. The personal information stored in the personal information storage unit 143 can be rewritten for each device owner. In addition, an RFID communication unit 21 is connected to the control unit 14. The RFID communication unit 21 transmits the personal information stored in the personal information storage unit 143 to the outside.

  On the other hand, an RFID reader 22 is disposed with respect to the apparatus main body 1. For example, a plurality of RFID readers 22 are installed at various locations on a school gate or school road. The RFID reader 22 reads the personal information transmitted from the RFID communication unit 21, identifies the device owner from the personal information, and installs the RFID reader 22 at the device owner's home or the like by communication means (not shown). As position information.

  In this way, the apparatus main body 1 is also carried in a pocket or the like with the switch 3 turned on. When the device owner passes near the RFID reader 22 installed at each school gate or school road, personal information transmitted from the RFID communication unit 21 is read by the RFID reader 22, and the device is read from the personal information. The owner is identified. Thereby, the installation location of the RFID reader 22 is notified as position information to the home of the identified device owner.

  Therefore, even in this way, the same effect as in the first embodiment can be obtained.

  In addition, this invention is not limited to the said embodiment, In the implementation stage, it can change variously in the range which does not change the summary. For example, in the above-described embodiment, the position information notification device having an independent configuration has been described. However, the position information notification device may be integrated into a mobile phone or a PHS. In this case, the rechargeable battery 2 may be used not only as a position information notification device but also as a power source for a mobile phone or a PHS.
