Description

  The present invention relates to a disaster prevention warehouse that stores disaster prevention tools.

  As a disaster prevention warehouse, a solar cell panel, a storage battery, and an outdoor lamp are known, and the outdoor lamp receives power from the storage battery at night and is automatically turned on (see, for example, Patent Document 1).

JP 2014-189964 (paragraphs [0019], [0024])

  However, in a conventional disaster prevention warehouse, there may have been a situation in which a storage battery prepared for disaster prevention has expired at the time of a disaster and cannot supply sufficient power.

  This invention is made | formed in view of the said situation, and it aims at provision of the warehouse for disaster prevention which can prevent that the storage battery provided for disaster prevention has expired at the time of a disaster.

  The invention of claim 1 made to achieve the above object comprises a solar battery panel, a storage battery stored in the solar battery panel, and an outdoor lamp that is powered from the storage battery and automatically lit only at night. Deterioration determining means for determining whether or not the voltage drop rate of the storage battery that is feeding power to the outdoor lamp is greater than a predetermined reference value, and the voltage drop rate is more than the reference value. When it is large, it is a disaster prevention warehouse provided with a notifying means for notifying that fact.

  The invention of claim 2 includes a plurality of loads including the outdoor lamp and a load that can receive power from the storage battery during a detection period from when the outdoor lamp is automatically turned on until the determination by the deterioration determining unit is completed. 2. The disaster prevention warehouse according to claim 1, further comprising a time scheduler that limits the load to a constant load including the outdoor light and enables the arbitrary load to receive power from the storage battery after the detection period has elapsed.

  Invention of Claim 3 is provided with the inverter circuit which converts the output voltage of the said storage battery into the alternating voltage of 100 [V], and the outlet socket for connecting arbitrary rechargeable electric equipment to the output of the said inverter circuit, The time scheduler is a warehouse for disaster prevention according to claim 2, wherein the inverter circuit can receive power from the storage battery only for a predetermined period.

  Invention of Claim 4 is provided with the indoor switch provided in the inside of the warehouse for disaster prevention, and the manual switch which can connect the said indoor light to the said storage battery irrespective of the said time scheduler. It is a warehouse for disaster prevention given in any 1 claim.

  According to a fifth aspect of the present invention, a plurality of the reference values are set, and the notification means performs notification by changing the notification mode step by step every time the voltage drop rate exceeds each of the reference values. It is a warehouse for disaster prevention according to any one of the claims.

  The invention according to claim 6 is the disaster prevention warehouse according to any one of claims 1 to 5, wherein the notification means is provided with a notification LED arranged at a position visible from the outside of the disaster prevention warehouse. .

  The invention according to claim 7 is provided with a display unit indicating disaster prevention on an outer surface of the disaster prevention warehouse, and the outdoor lamp is arranged to illuminate the display unit. It is a warehouse for disaster prevention as described in.

  Since the capacity that can be stored decreases when the storage battery deteriorates, the voltage drop rate of the storage battery (that is, the step-down amount per unit time of the output voltage of the storage battery) increases as the deterioration progresses under the same load connected condition. growing. And in the warehouse for disaster prevention of Claim 1, that is alert | reported when the voltage drop rate of the storage battery currently supplying electric power to an outdoor lamp is larger than a reference value. Thereby, replacement | exchange of the storage battery near expiration of a lifetime is promoted, and it can prevent that the storage battery has expired at the time of a disaster.

  In the warehouse for disaster prevention according to claim 2, during a detection period from when the outdoor light is automatically turned on until the determination of the deterioration of the storage battery is completed, the load that can receive power from the storage battery is limited to a certain load including the outdoor light. The Further, after the detection period has elapsed, an arbitrary load can receive power from the storage battery. As a result, the voltage drop rate is detected and determined every day after sunset under the same load condition, and the deterioration state of the storage battery can be accurately determined.

  In the disaster prevention warehouse according to claim 3, by providing an inverter circuit that operates by receiving power from the storage battery, any rechargeable electric device that is normally charged by a commercial power source can be charged by the power from the storage battery. . Here, even if charging of the rechargeable electrical device is completed, if the inverter circuit is operating, the inverter circuit itself consumes power, but the time scheduler allows the inverter circuit to receive power from the storage battery. Is limited, and wasteful power consumption can be suppressed.

  Monitoring of deterioration of the storage battery is unnecessary under the situation where a disaster actually occurs, and lighting in the disaster prevention warehouse is necessary when using the disaster prevention warehouse at night. On the other hand, the disaster prevention warehouse of claim 4 is excellent in convenience because it can illuminate the accommodation space by turning on the indoor lamp with a manual switch regardless of the time scheduler.

  According to the warehouse for disaster prevention of claim 5, since the notification mode changes stepwise as the storage battery progresses, battery replacement can be effectively promoted.

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows the appearance of the disaster prevention warehouse 10 of the present embodiment. The main body portion of the disaster prevention warehouse 10 generally has the same structure as that marketed as a so-called “storage”. Specifically, the disaster prevention warehouse 10 has a rectangular parallelepiped shape as a whole, and has two sliding doors 12A and 12A on the front surface. On the outer surfaces of the sliding doors 12A and 12A, a display unit 13 is provided for displaying that the warehouse 10 is for disaster prevention. The sliding doors 12A and 12A are provided with a locking device 12K, but are always unlocked.

  An outdoor lamp 17 is attached to the edge of the disaster prevention warehouse 10 above the sliding doors 12A and 12A at the center in the lateral direction. The outdoor lamp 17 includes an LED as a light source, for example, has a structure that emits light downward, and irradiates the display unit 13 with a part of the light. Thereby, when visually observing the disaster prevention warehouse 10 from a remote position, the display unit 13 can be easily read, and direct light from the outdoor lamp 17 does not enter the eyes of the viewer.

  A solar cell panel 15 (also referred to as a “solar cell module”) is attached to the upper surface of the disaster prevention warehouse 10. The area of the light receiving surface of the solar cell panel 15 is, for example, 1/10 or less compared to the area of the upper surface of the disaster prevention warehouse 10, and is arranged at a position closer to one side surface of the upper surface of the disaster prevention warehouse 10. Further, the solar cell panel 15 is held in a posture capable of receiving sunlight efficiently by the support legs 15K.

  A control box 16 is attached to the side surface of the disaster prevention warehouse 10 that is closer to the solar cell panel 15. Further, one side surface of the control box 16 is a rotating door 16F. In addition, the upper surface of the control box 16 is inclined so as to be lowered toward the one side surface.

  As shown in FIG. 2A, the control box 16 accommodates a charge / discharge controller 20, a storage battery 21, an inverter circuit 22, and a voltage drop rate detection circuit 23. A cable 15 </ b> C (see FIG. 1) extending from the solar cell panel 15 is drawn into the control box 16 and connected to the charge / discharge controller 20.

  As shown in FIG. 2B, an indoor lamp 18 is attached to the front edge of the ceiling surface in the disaster prevention warehouse 10 in the center in the lateral direction, and operation switches 19 and 19 are provided at both ends. Yes. The indoor lamp 18 uses an LED as a light emission source in the same manner as the outdoor lamp 17.

  A relay box 30 is attached to the inner surface of the side wall of the disaster prevention warehouse 10 to which the control box 16 is attached. Further, a harness that passes through a through hole (not shown) formed in the side wall connects the control box 16 and the relay box 30. The charge / discharge controller 20, the storage battery 21, the outdoor lamp 17, the indoor lamp 18, and the like are connected via a terminal block (not shown) provided in the relay box 30 to configure the electric circuit shown in FIG. 3. Hereinafter, this electric circuit will be described in detail.

  Between the positive and negative electrodes of the solar cell panel 15, the storage battery 21, the outdoor lamp 17, the indoor lamp 18, and the inverter circuit 22 as “a plurality of loads” according to the present invention are connected in parallel via the charge / discharge controller 20. It is connected. In other words, a plurality of loads such as the outdoor lamp 17 are connected in parallel between the positive and negative electrodes of the solar battery panel 15 and the storage battery 21 as a power source. And when the output voltage of the solar cell panel 15 is higher than the storage battery 21, the output voltage of the solar cell panel 15 is applied to each load, and conversely, when the output voltage of the storage battery 21 is higher than the solar cell panel 15. The output voltage of the storage battery 21 is applied to each load. That is, at night, the output voltage of the storage battery 21 is applied to each load. The negative electrodes of the solar cell panel 15 and the storage battery 21 are connected to the ground.

  A switch is connected in series with each load between the positive and negative electrodes of the solar cell panel 15 and the storage battery 21. Specifically, a timer switch 25 is provided corresponding to the indoor light 18, an outdoor light switch 29 built in the charge / discharge controller 20 is provided corresponding to the outdoor light 17, and a time corresponding to the inverter circuit 22 is provided. A built-in switch 26S1 of the scheduler 26 is provided. The timer switch 25 is normally in an off state, and when any one of the pair of operation switches 19 and 19 in the disaster prevention warehouse 10 is manually operated, the timer switch 25 takes a predetermined time (for example, 3 minutes). The on state is maintained and the power is turned off after a predetermined time. The timer switch 25 consumes electric power when it is in an on state, and becomes a load on the solar battery panel 15 and the storage battery 21.

  The time scheduler 26 has a plurality of built-in switches 26S2, 26S3,... In addition to the built-in switch 26S1, and each built-in switch 26S1 according to a predetermined time schedule in a time zone excluding a detection period to be described later. , 26S2, 26S3,. As a result, any load can be conductively connected to the solar cell panel 15 and the storage battery 21 or disconnected. Therefore, the time scheduler 26 includes a microcomputer (not shown), for example, and always consumes power. In this respect, the time scheduler 26 also becomes a load on the solar cell panel 15 and the storage battery 21.

  The inverter circuit 22 has a general circuit configuration in which a plurality of FETs are switched by, for example, a microcomputer to convert direct current into alternating current. The output of the inverter circuit 22 is connected to an outlet 31 provided in the relay box 30. The outlet 31 is connected with, for example, a plug that extends from a rechargeable wireless communication device 27 (corresponding to the “rechargeable electrical device” of the present invention) that is necessary in the event of a disaster. Here, even when a load such as the wireless communication device 27 is not connected to the outlet 31, the inverter circuit 22 consumes power because the FET is turned on and off. In view of this, the time scheduler 26 limits the time for operating the inverter circuit 22 to a certain time (for example, 2 hours).

  The charge / discharge controller 20 includes a microcomputer 20M and a power amount detection circuit 28 that detects a power generation amount P1 of the solar battery panel 15. Then, the microcomputer 20M executes, for example, the lighting control program PG1 shown in FIG. 4 at a predetermined cycle (for example, 10 minutes), and performs on / off control of the outdoor light switch 29 based on the detection result of the electric energy detection circuit 28.

  That is, when the lighting control program PG1 is executed, it is first checked whether FLG1 is “1” (S10). Here, if FLG1 is not “1” (NO in S10), it means that the outdoor lamp 17 is not lit, and in this case, the power generation amount P1 of the solar cell panel 15 is the first threshold value. It is checked whether or not K1 or less (S11). If the power generation amount P1 of the solar panel 15 is equal to or less than the first threshold value K1 (YES in S11), it is determined that it is night, the outdoor light switch 29 is turned on, and the outdoor light 17 is turned on (S12). , FLG1 is set to “1” (S13), and then the lighting control program PG1 is exited. On the other hand, if the power generation amount P1 of the solar battery panel 15 is not less than or equal to the first threshold value K1 (NO in S11), it is determined that it is not night, and the lighting control program PG1 is immediately exited.

  On the other hand, when it is first checked whether FLG1 is “1” (S10), if FLG1 is “1” (YES in S10), the outdoor lamp 17 is lit. In this case, it is determined whether or not the power generation amount P1 of the solar cell panel 15 is equal to or greater than the second threshold value K2 (S14). If the power generation amount P1 of the solar battery panel 15 is equal to or greater than the second threshold value K2 (YES in S14), it is determined that the day is dawning, the outdoor light switch 29 is turned off, and the outdoor light 17 is turned off ( S15), FLG1 is reset to "0" (S16), and the lighting control program PG1 is exited. On the other hand, if the power generation amount P1 of the solar battery panel 15 is not greater than or equal to the second threshold value K2 (NO in S14), it is determined that the day has not dawned, and the lighting control program PG1 is immediately exited.

  Thereby, the outdoor lamp 17 receives power from the storage battery 21 only at night and is automatically turned on. Note that the second threshold value K2 is set to be larger than the first threshold value K1, thereby preventing the outdoor light switch 29 from being frequently switched on and off at sunset and sunrise.

  As shown in FIG. 3, a voltage drop rate detection circuit 23 is connected in the middle of the conductive line from the storage battery 21 to the outdoor lamp 17. The voltage drop rate detection circuit 23 includes a voltage detection circuit and a microcomputer (not shown) and a three-color LED 24. As shown in FIGS. 1 and 2, the three-color LED 24 is attached to a surface of the control box 16 facing the front of the disaster prevention warehouse 10.

  The microcomputer executes the deterioration determination program PG2 shown in FIG. 5 by using the outdoor light switch 29 as a trigger. When the deterioration determination program PG2 is executed, the output voltage of the storage battery 21 is detected as the first voltage E1 (S20), then a timer is started (S21), and the timer determines a certain time T1 (for example, 1 hour). When the time is measured (YES in S22), the output voltage of the storage battery 21 is detected as the second voltage E2 (S23). And from these 1st voltage E1, 2nd voltage E2, and fixed time T1, the amount of fall of the output voltage of storage battery 21 per unit time is computed as voltage drop rate R1 (= (E1-E2) / T1) ( S24).

  If the voltage drop rate R1 is less than the first reference value X1 (YES in S25), the three-color LED 24 is lit in green (S27), and the voltage drop rate R1 is greater than or equal to the first reference value X1 and the second reference value. If less than X2 (NO in S25, NO in S26), the three-color LED 24 is lit yellow (S28), and if the voltage drop rate R1 is equal to or greater than the second reference value X2 (NO in S25, YES in S26) The three-color LED 24 is lit red (S29), and the process exits from the deterioration determination program PG2. That is, the timer switch 25 determines the voltage drop rate of the storage battery 21 every day after the outdoor lamp 17 is turned on until a certain time T1 (for example, 1 hour) elapses, and the determination result is displayed. Notification is made using the three-color LED 24.

  In the present embodiment, the microcomputer when executing steps S20 to S26 of the deterioration determination program PG2 in the timer switch 25 corresponds to the deterioration determination means according to the present invention, and steps S27 to S27 of the deterioration determination program PG2. The microcomputer and the three-color LED 24 when executing S29 correspond to the notification means according to the present invention. The period from when the outdoor lamp 17 is lit until the determination by the timer switch 25 is completed corresponds to the above-described detection period.

  This completes the description of the configuration of the disaster prevention warehouse 10 of the present embodiment. The disaster prevention warehouse 10 is installed in an evacuation area from disasters such as earthquakes and floods, and accommodates and uses disaster prevention equipment such as helmets, first aid kits, cold protection equipment, radios and emergency foods. And the operation | movement which produces electric power with the solar cell panel 15 in the daytime, charges the storage battery 21, and lights the outdoor lamp 17 by the storage battery 21 at night is repeated every day.

  Here, as shown in FIG. 6, the transition of the output voltage of the storage battery 21 for one day is shown. The output voltage of the storage battery 21 is lowest before sunrise, and gradually increases after charging by the solar battery panel 15 is started after sunrise. It should be noted that, even during the day, the voltage drop rate detection circuit 23, the time scheduler 26, and the electric device connected to the solar cell panel 15 are operated by the time scheduler 26, but the solar cell panel is compared with the power consumption thereof. Since the power generation amount by 15 is large, the storage battery 21 is charged. Then, the charging of the storage battery 21 is completed during the day, and the output voltage of the storage battery 21 becomes constant. Further, when the sun goes down, the outdoor lamp 17 is turned on, and the power of the storage battery 21 is consumed.

  Here, when the storage battery 21 deteriorates, the capacity that can be stored decreases. Under the condition that the same load is connected, when the deterioration progresses, the voltage drop rate R1 of the storage battery 21 increases as shown by the broken line in FIG. Become. On the other hand, in the disaster prevention warehouse 10 of the present embodiment, only a limited load consisting of the outdoor lamp 17, the voltage drop rate detection circuit 23, and the time scheduler 26 is provided every day for a certain detection period after sunset. The storage battery 21 is limited so that it can receive power, and the voltage drop rate detection circuit 23 detects the voltage drop rate of the storage battery 21 during the detection period, and the three-color LED 24 is displayed in a color corresponding to the magnitude of the voltage drop rate. Make it emit light.

  Thereby, the administrator of the disaster prevention warehouse 10 can visually recognize the three-color LED 24 from the outside of the disaster prevention warehouse 10 and confirm the deterioration state of the storage battery 21. Specifically, when the three-color LED 24 is lit in green, the voltage drop rate R1 is less than the first reference value X1, and it can be determined that the deterioration of the storage battery 21 has not progressed. In addition, when the three-color LED 24 is lit yellow, the voltage drop rate R1 is equal to or higher than the first reference value X1 and lower than the second reference value X2, and the storage battery 21 has been deteriorated, but there is a delay. You are prompted to prepare for battery replacement. Further, when the three-color LED 24 is lit in red, the voltage drop rate R1 is equal to or higher than the second reference value X2, and the storage battery 21 is almost out of service life, so that the storage battery 21 is promptly replaced.

  Thus, according to the warehouse 10 for disaster prevention of this embodiment, replacement | exchange of the storage battery 21 with near end of life is promoted, and it can prevent that the storage battery 21 has expired at the time of a disaster. Moreover, since the notification mode changes step by step as the storage battery 21 deteriorates, battery replacement can be effectively promoted. Further, since the voltage drop rate R1 is detected and determined every day after sunset under the same load condition, it is possible to accurately determine the deterioration state of the storage battery 21. Furthermore, since the three-color LED 24 for notifying the deterioration of the storage battery 21 is arranged at a position that can be visually recognized from the outside of the disaster prevention warehouse 10, the deterioration of the storage battery 21 can be easily performed without opening the disaster prevention warehouse 10 one by one. Can be confirmed. In addition, since the inverter circuit 22 that operates by receiving power from the storage battery 21 is provided, normally any rechargeable electric device that is charged by a commercial power source can be charged by the power from the storage battery 21.

  In the situation where a disaster actually occurs, it is not necessary to monitor the deterioration of the storage battery 21. When the disaster prevention warehouse 10 is used at night, lighting in the disaster prevention warehouse 10 is required. On the other hand, the disaster prevention warehouse 10 is excellent in convenience because the indoor lamp 18 can be turned on by manual operation of the operation switch 19 regardless of the time scheduler 26 and the interior of the disaster prevention warehouse 10 can be illuminated.
