Description

  The present invention relates to a street light with an AED storage box.

  In order to save many lives, an automatic external defibrillator (hereinafter referred to as “AED”) is installed in a common space such as a station or public facilities. The AED is usually installed in a storage box. In recent years, AEDs are increasingly installed not only indoors but also outdoors. By the way, although AED operates with a battery, when the ambient temperature of AED is extremely high or low, there exists a possibility that the performance of AED may deteriorate. Therefore, when installing AED outdoors, the storage box provided with the air conditioner is utilized (refer patent document 1).

JP 2012-5661 A

  In the storage box described in Patent Document 1, the air conditioner obtains electric power from an external power source such as a commercial power source. Therefore, the air conditioner stops at the time of a power failure of the external power supply, and the ambient temperature of the AED becomes unstable.

  Then, this invention was created in view of these problems, and makes it a subject to provide the street light with an AED storage box which can perform the stable supply of the electric power to an air conditioner.

  The present invention for solving the above-described problems includes a solar power source for performing solar power generation, a lighting device, an AED storage box, a connection part for connecting an external power source, a battery, and a control for controlling the flow of electricity. The AED storage box includes an air conditioner that adjusts an internal temperature, the battery can be charged from the solar power source and the external power source, and supplies power to the lighting device and the air conditioner. The control device includes a charging control unit that controls charging of the battery, and the charging control unit charges the solar power with priority over the external power. It is a street light with a featured AED storage box.

  According to such a configuration, since power is supplied from the battery to the air conditioner, it is possible to stably supply power to the air conditioner even during a power failure. Therefore, the ambient temperature of the AED can be kept at an appropriate temperature. In addition, since the battery is preferentially charged from the solar power supply during sunshine, the use of external power can be stopped. Therefore, the power cost of external power can be reduced. Furthermore, since the lighting device is provided, when the AED is installed at a position where there is no outdoor illumination, the installation position of the AED can be clearly indicated even at night.

  In the street light with an AED storage box according to the present invention, the charging control unit prioritizes the power supplied from the solar power source over the external power source when the voltage supplied from the solar power source is equal to or higher than a predetermined threshold. It is preferable to charge the battery.

  According to such a configuration, when the supply voltage of the solar power supply is small, the charging efficiency of the battery can be increased by charging from the external power supply.

  In the street light with an AED storage box according to the present invention, the control device includes a power supply control unit that controls power supply from the battery to the lighting device and the air conditioner, and the power supply control unit includes the power supply control unit, When the power supply from the external power supply is stopped, it is preferable to continue the power supply to the lighting device while stopping the power supply to the air conditioner after a lapse of a certain time from the power supply stop.

  According to such a configuration, it is possible to stably supply power to the air conditioner and maintain the ambient temperature of the AED at an appropriate temperature within a certain time even during a power failure. That is, a backup power source for a certain time can be secured. It should be noted that, after a certain period of time has elapsed, priority can be given to the lighting device to avoid a situation where an AED cannot be found at night.

  Furthermore, in the street light with an AED storage box, the power supply control unit resumes power supply to the air conditioner when power supply from the external power source is resumed after power supply is stopped, and charging of the battery is completed. When the power supply from the external power supply is stopped again before, the power supply to the air conditioner is stopped when the time obtained by adding the first power supply stop time and the second power supply stop time exceeds the predetermined time. However, it is preferable to continue power supply to the lighting device.

  According to such a configuration, it is possible to avoid a situation in which when the power failure occurs a plurality of times over a long time, the power of the battery is lost and the lighting device cannot be turned on.

  On the other hand, in the street light with an AED storage box according to the present invention, the control device includes a power supply control unit that controls power supply from the battery to the lighting device and the air conditioner. When the power supply from the external power supply is stopped, it is preferable that the power supply to the lighting device is continued while the power supply to the air conditioner is stopped if the remaining charge of the battery falls below a certain value.

  According to such a configuration, the remaining charge of the battery can be accurately managed without being affected by the power failure time of the external power supply or the sunshine condition.

  ADVANTAGE OF THE INVENTION According to this invention, the stable supply of the electric power to an air conditioner can be performed.

The solar cell module may be a single-sided light receiving type in which cells are provided on one side of the panel. In this case, it is preferable to incline the solar cell module so that the light receiving surface faces obliquely upward.

  The illumination device 20 includes an LED illumination 21 and an automatic lighting device 22. For the LED illumination 21, for example, a device capable of adjusting light in three stages with power consumption of 9 W is adopted. The LED illumination 21 has a specification for illuminating the lower side, and is arranged so as to project to the front side when the street light 1 with an AED storage box is viewed from the front. The LED illumination 21 is provided below the solar power source 10 and above the AED storage box 30.

  The automatic lighting device 22 detects the brightness of the outside and automatically turns on the illumination when the outside becomes dark and automatically turns off when the outside becomes bright. The brightness of the illumination is adjusted in three stages according to the external brightness. The automatic lighting device 22 is provided so as to protrude to the opposite side of the LED lighting 21 (the back side when the street light 1 with an AED storage box is viewed from the front).

  The AED storage box 30 has a rectangular parallelepiped shape that can store an AED therein, and has a box shape including an opening / closing door 31 on the front surface. The AED storage box 30 is bridged and attached between the adjacent columns 3 and 3. The AED storage box 30 is formed of a plate material obtained by baking and coating an iron plate, and a heat insulating material may be laid inside the box. The AED storage box 30 is installed so that an adult can easily take out the AED, for example, the bottom of the box is about 1200 mm above the ground. The AED storage box 30 includes an air conditioner 33 (see FIG. 2) that adjusts the internal temperature.

  The air conditioner 33 includes a cooling device that cools the inside of the box, a heating device that warms the inside of the box, and a temperature sensor. The cooling device includes a fan, and lowers the temperature in the box by flowing the air in the box while introducing outside air into the box. The fans are provided, for example, at two locations, an upper portion on the back of the box and a lower portion on the front. By providing the fans diagonally, the air in the box flows efficiently. The cooling device operates when the temperature inside the box exceeds 40 ° C, and stops when the temperature inside the box drops to 30 ° C.

  The heating device is made of a silicon rubber heater, and raises the temperature in the box by energizing it. The heating device is activated when the temperature in the box is lower than 10 ° C, and is stopped when the temperature in the box is increased to 20 ° C. In addition, the operation start temperature and stop temperature of the cooling device and the heating device are examples, and can be appropriately changed according to the climate of the area where the street lamp 1 with the AED storage box is installed. The temperature sensor is a bimetal sensor and is installed in a box. A converter 35 is provided in the electric cord 34 for supplying electricity to the air conditioner 33. The converter 35 is a DC / AC converter that converts direct current into alternating current, and converts the direct current power from the battery 40 into alternating current power and flows it to the air conditioner 33.

  An alarm buzzer is attached to the open / close door 31 of the AED storage box 30. The alarm buzzer sounds when the door 31 is opened and stops when the door 31 is closed. As security equipment, a security red light that rotates when the door 31 is opened or a security camera that photographs the front of the AED storage box 30 may be attached. It is preferable that these crime prevention facilities operate with the electric power of the external power source 60.

  An installation location display board (sign board) 36 is provided above the AED storage box 30. The installation location teaching plate 36 is bridged and attached between the adjacent columns 3 and 3 below the lighting device 20. Since the installation location teaching plate 36 is provided at a high position above the AED storage box 30, it can be visually confirmed that the AED is stored even from a distance. In addition, since the installation location teaching plate 36 is provided below the lighting device 20, it can be visually recognized that the AED is stored even at night.

  The external power source 60 (see FIG. 2) is a commercial power source in this embodiment. The external power source 60 is not limited to a commercial power source, and may be a power source using a private generator, for example. The connection part for connecting the external power supply 60 is an outdoor outlet 61 formed on the back surface of the second storage box 41 described later. The outdoor outlet 61 is connected to an electric wire wired in the ground. An electric cord 62 connected to the control device 50 is inserted into the outdoor outlet 61. The electric cord 62 is provided with a converter 63. The converter 63 is an AC / DC converter that converts alternating current into direct current, and converts alternating current power from the external power source 60 into direct current power and flows it to the battery 40.

  The battery 40 (see FIG. 2) is electrically connected to the solar power supply 10 and the external power supply 60 via the control device 50, and can be charged from the solar power supply 10 and the external power supply 60. The battery 40 is electrically connected to the lighting device 20 and the air conditioner 33 of the AED storage box 30 via the control device 50, and can supply power to the lighting device 20 and the air conditioner 33. The battery 40 is stored in the second storage box 41 together with the control device 50 (see FIG. 2).

  The battery 40 is provided with an indicator lamp 45. The indicator lamp 45 is activated when the external power supply 60 fails. The indicator lamp 45 is lit according to the remaining amount of the battery 40. When the remaining amount of the battery 40 is large and both the air conditioner 33 and the lighting device 20 are operable, the indicator lamp 45 is lit in green. When the remaining amount is small and only the lighting device 20 can be operated, the light turns red. In addition, when the illuminating device 20 cannot also operate | move, red blinks.

  The second storage box 41 is attached between the adjacent columns 3 and 3 below the AED storage box 30. The second storage box 41 has a rectangular parallelepiped shape in which the battery 40 and the control device 50 can be stored, and has a box shape with an opening / closing door 43 on the front surface. A peep hole is formed in the open / close door 43 so that the indicator lamp 45 of the battery 40 can be seen from the outside.

  As shown in FIG. 2, the control device 50 includes a charge control unit 51 and a power supply control unit 52, and controls the electric flow of the battery 40. The charging control unit 51 is a part that controls charging of the battery 40. The charging control unit 51 performs charging so that the charging amount of the battery 40 is always fully charged in a normal time when no power failure occurs. In addition, it is not always full charge, but when the charge amount of the battery 40 becomes a certain value or less, the electric supply may be started and the battery 40 may be charged to full charge.

  When the supply voltage from the solar power supply 10 is equal to or higher than a predetermined threshold, the charge control unit 51 performs control to charge the battery with priority given to the power supplied from the solar power supply 10 over the external power supply 60. Specifically, the charge control unit 51 includes a comparison unit, a determination unit, and a data storage unit. The comparison unit receives the supply voltage value of the solar power supply 10 and compares it with a threshold value input in advance. The threshold is an amount of electric power (voltage value) that can efficiently charge the battery 40, and can be set as appropriate. In the present embodiment, the threshold value is set smaller than the amount of power of the external power source 60, and the energy saving effect by using the solar power source 10 is prioritized over the charging efficiency of the external power source 60. The comparison unit transmits to the determination unit whether the supply voltage from the solar power supply 10 is larger or smaller than the threshold value. The determination unit selects either the solar power source 10 or the external power source 60 in accordance with a signal from the comparison unit, and switches a branch switch (not shown) for the wires between the solar power source 10, the external power source 60, and the battery 40. Send a signal.

  Note that the threshold power amount may be set to the same value as the supply voltage of the external power supply 60, and the battery 40 may be charged by selecting the higher one of the solar power supply 10 and the external power supply 60. In this case, the battery 40 can be charged more efficiently.

  During normal daytime, the supply voltage from the solar power supply 10 is larger than the threshold value (and is larger than the voltage value of the supply power from the external power supply 60), so the battery 40 is charged with the supply power from the solar power supply 10. (See FIG. 3A). In FIG. 3, the flow of electricity is indicated by a bold line. At the time of sunrise or sunset, the supply voltage from the solar power supply 10 is smaller than the supply voltage of the external power supply 60. By charging with the power supplied from the power supply 10, consumption of power supplied from the external power supply 60 is suppressed to save electricity costs. Since there is no power supplied from the solar power supply 10 at night during normal times, the battery 40 is charged with the power supplied from the external power supply 60 (see FIG. 3B). Note that, in the daytime at the time of a power failure, the determination unit receives a power failure occurrence signal from the converter 63 and charges the battery 40 with the power supplied from the solar power source 10.

  The power supply control unit 52 controls power supply from the battery to the lighting device 20 and the air conditioner 33 during a power failure. When the power supply from the external power supply 60 is stopped due to a power failure or the like, the power supply control unit 52 performs control to continue power supply to the lighting device 20 while stopping power supply to the air conditioner 33 after a certain period of time has elapsed since the power supply was stopped. Do. Specifically, the power supply control unit 52 includes a timer unit, a determination unit, and a data storage unit. When a power failure occurs, the timer unit receives a power failure occurrence signal from the converter 63 and starts counting the power failure time. When the power failure time exceeds a certain time, the timer unit transmits a signal that the time has elapsed to the determination unit. The predetermined time is input to the data storage unit. The fixed time is set to 24 hours in summer and 12 hours in winter, for example. The summer season is set to April to September including summer, and the winter season is set to October to March including winter. The time setting and season setting can be changed as appropriate according to the climate of the installation area. For example, in an extremely cold region, it is preferable to shorten the winter setting time or lengthen the winter period.

  When the determination unit receives a signal indicating that the power failure time has passed a certain time, the determination unit transmits a signal for continuing power supply to the lighting device 20 while stopping power supply to the air conditioner 33. In this way, by supplying power only to the lighting device 20 after a certain amount of power failure time has elapsed, it is possible to avoid as much as possible the situation that the lighting device 20 is not turned on at night and the installation position of the AED is not found. can do. That is, in the present embodiment, priority is given to the discovery of the AED over the prevention of the performance degradation of the AED due to the temperature change. In the daytime, even when the external power supply 60 is out of power, the battery 40 is charged to some extent by the power supply from the solar power supply 10, so the power supply time to the lighting device 20 can be extended. In addition, when the power failure time exceeds the set time in the daytime period, the lighting device 20 is automatically turned off by the automatic lighting device 22, and therefore when the power supply to the air conditioner 33 is stopped, the battery 40 Almost no electricity is consumed. When the power failure time exceeds the set time in the night time zone, the lighting device 20 consumes the power of the battery 40, but the power supply to the air conditioner 33 is stopped ((b in FIG. 4). )), So power consumption is small. Also in FIG. 4, the flow of electricity is indicated by a bold line. In addition, before the power failure time elapses for a certain time, power is supplied from the battery 40 to both the lighting device 20 and the air conditioner 33 (see FIG. 4A).

  When power supply from the external power supply 60 is restored at night, the determination unit receives a power supply restoration signal from the converter 63 and transmits a signal for resuming power supply to the air conditioner 33. Then, power is supplied until the battery 40 is fully charged. If the power supply is restored in the daytime and the voltage of the power supplied from the solar power supply 10 is larger than the voltage of the power supplied from the external power supply 60, the power supply from the external power supply 60 is not performed, and the solar power supply 10 Continue to prioritize the power supply.

  When the power supply from the external power supply 60 is stopped again before the charging of the battery 40 is completed (before full charge) after the power supply of the external power supply 60 is restored, the power supply control unit 52 performs the first power supply. When the time obtained by adding the stop time and the second power supply stop time exceeds a set time (fixed time), control is performed so that power supply to the lighting device 20 is continued while power supply to the air conditioner 33 is stopped. It is configured. That is, the timer unit adds the power failure time until the battery 40 is fully charged, and determines whether or not the total power failure time exceeds the set time. In other words, when the battery 40 is fully charged, the power failure time is reset, and when a power failure occurs again, the power failure time starts counting from zero.

  According to the control as described above, even when a power failure occurs three or more times before the battery 40 is fully charged, each power failure time is added and compared with the set time. By controlling in this way, the remaining charge of the battery 40 is prevented from becoming lower than the minimum value (remaining charge enough to use the lighting device 20 for a predetermined number of days) even if a plurality of power outages occur. Can do.

  In the present embodiment, it is set that charging is completed with full charge, but the present invention is not limited to this. For example, the state in which the remaining charge of the battery 40 is 90% may be set as the time when charging is completed at the time of a power failure. In this case, the power failure time is reset when the remaining charge is 90%, but the battery 40 is charged until the amount of charge reaches 100%.

  According to the street light 1 with an AED storage box configured as described above, since power is supplied from the charged battery 40 to the lighting device 20 and the air conditioner 33, the power to the air conditioner 33 is maintained even during a power failure. Stable supply. In other words, it can be said that the street light 1 with an AED storage box has a power failure backup function for 24 hours in summer and 12 hours in winter. Therefore, even if a power failure occurs, the ambient temperature of the AED in the AED storage box 30 can be kept at an appropriate temperature for a certain time. This can prevent performance degradation due to the ambient temperature of the AED. In particular, since the gel of the electrode pad can be prevented from freezing at low temperatures, the electrode pad can be brought into close contact with the skin of the person to be rescued. Moreover, since the performance degradation of the battery of AED at the time of high temperature or low temperature can be prevented, the AED can be operated in a suitable state.

  Furthermore, in the present embodiment, since the battery 40 is always controlled to be fully charged by the power supply control unit 52, it is possible to secure as much back-up time as possible during a power failure.

  Moreover, since the battery 40 can be charged from the solar power supply 10 during sunshine, the use of power from the external power supply 60 can be stopped. In particular, since the solar power supply 10 preferentially charges the battery 40 during sunshine, the use of power from the external power supply 60 can be stopped as much as possible. Therefore, energy saving and saving of electricity bill can be achieved greatly. In addition, since the external power source 60 is used at night, it is possible to use night power that is inexpensive.

  Further, since the lighting device 20 is provided, the AED installation position can be clearly indicated even at night when the AED is installed at a position without outdoor illumination, serving as a street light. Moreover, it is easy to perform a lifesaving treatment at night by the light of the lighting device 20. Since the illumination device 20 is the LED illumination 21, power consumption can be reduced.

  In addition, when power supply from the external power supply 60 is stopped, the power supply control unit 52 performs control to continue power supply to the lighting device 20 while stopping power supply to the air conditioner 33 after a certain time has elapsed since the power supply stop. Since it is comprised in this way, if it is within a fixed time also at the time of a power failure, the stable supply of electric power to the air conditioner 33 can be performed, and the ambient temperature of AED can be kept at appropriate temperature. After a certain period of time has passed, priority can be given to the power supply to the lighting device 20 to avoid a situation in which an AED cannot be found at night. Furthermore, since the illumination apparatus 20 uses the LED illumination 21, it can perform illumination for a long time with low power consumption.

  As mentioned above, although the form for implementing this invention was demonstrated, this invention is not the meaning limited to the said embodiment, A design change is possible suitably in the range which does not deviate from the meaning of this invention. For example, in the embodiment, the power supply control unit 52 counts the power outage time from the start of the power outage and stops the power supply to the air conditioner 33 with the power outage time as a reference, but is not limited thereto. Absent. The remaining charge (voltage value) of the battery 40 may be detected and managed, and power supply to the air conditioner 33 may be stopped when the remaining charge becomes a certain value or less. The remaining charge is preferably set to a value that allows the lighting device 20 to operate for a certain time (for example, about two days). According to such a configuration, the power supply to the air conditioner 33 can be made as long as possible as compared with the above-described embodiment, so that a decrease in the performance of the AED can be suppressed as much as possible.
