Description

[Technical Field]

[0001] The present invention relates to a security system, method and computer program. [Background technology]

[0002] There is a known technology for supplying power to an electrical load using a distributed power source, such as a storage battery mounted on a solar power generation device, in addition to AC power supplied from a grid power source. Regarding the technology for supplying power to an electrical load using a distributed power source, there is a known technology that eliminates the need to adjust the voltage, frequency, and phase with the grid power source, thereby reducing the introduction cost and enabling at least a part of the electrical load to operate even if the power supply from the grid power source is stopped (see, for example, Patent Document 1).

[0003] According to this technology, the power supply system includes a DC power supply device and an electrical load. The DC power supply device receives power from an independent power supply that is separate from the power grid and outputs DC power. The electrical load is connected to a first power supply line that receives power from the power grid. The electrical load is also connected to a second power supply line that receives power from the DC power supply device. Therefore, the electrical load includes a power supply unit that can receive power from both the first power supply line and the second power supply line. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-131421 Summary of the Invention [Problem to be solved by the invention]

[0005] When a disaster such as flooding occurs and a power outage occurs, cutting off the supply of AC power from the grid to a building, power is supplied to electrical loads using distributed power sources. However, if the storage battery installed in the solar power generation system is submerged in water, it will no longer be possible to supply power to the electrical loads using the distributed power sources. If a power outage causes AC power to be cut off from the grid power supply and it becomes impossible to supply power to electrical loads using distributed power sources, the security functions of the building will no longer be able to function. An object of the present invention is to provide a security system, method, and program that can maintain the security functions of a building in the event of a disaster. [Means for solving the problem]

[0006] In order to solve the above problem, one embodiment of the present invention is a security system for an apartment building with multiple floors, each floor having multiple compartments corresponding to multiple households occupying the building, and common areas other than the compartments, the security system comprising: a storage battery that stores electricity generated by a distributed power source, the storage battery being installed in one of the common areas on the second floor or higher; a power conditioner that is installed at a height of 30 cm or more above the floor of the first floor of the building and that supplies the electricity stored in the storage battery to electrical loads in the building when power supply from the grid power source is cut off; a communication device that is installed in one of the common areas at a height of 180 cm or more above the floor of the common area on the first floor and that operates using electricity supplied by the power conditioner; and an access point installed in each of the compartments, the access point being installed at a height of 30 cm or more above the floor of the compartment and connected to the communication device via a communication cable wired at a height near the ceiling of the floor on which it is installed.

[0007] In this way, the security system is equipped with a storage battery that stores electricity generated by the distributed power source and a power conditioner that supplies the electricity stored in the storage battery to the electrical loads in the building when power supply from the grid power source is stopped.The storage battery and power conditioner are installed at a height of 30 cm or more above the floor of the first floor of the building, so they will not be submerged even if a disaster such as a flood occurs and the building is flooded several tens of cm above the floor of the first floor.Even in the event of a disaster, the electricity stored in the storage battery can be supplied to the electrical loads in the building, so the security functions of the building can be maintained in the event of a disaster.

[0008] One embodiment of the present invention is a method for an apartment building with multiple floors, each floor having multiple sections corresponding to multiple households occupying the buildings, and common areas other than the sections, the method comprising the steps of: a storage battery installed in one of the common areas on the second floor or higher storing electricity generated by a distributed power source; a power conditioner installed at a height of 30 cm or more from the floor of the first floor of the building supplying the electricity stored in the storage battery to an electrical load included in the building when power supply from the grid power source is stopped; a communication device installed in one of the common areas at a height of 180 cm or more from the floor of the first floor operating with electricity supplied by the power conditioner; and an access point installed in each of the sections at a height of 30 cm or more from the floor of the section communicating with the communication device via a communication cable wired at a height near the ceiling of the floor on which it is installed. The information processing method according to one embodiment of the present invention is essentially the same invention as the security system, except that it is in a different category, and provides similar actions and effects.

[0009] One embodiment of the present invention is a computer program that causes a computer in an apartment building with multiple floors, each floor having multiple compartments corresponding to multiple households occupying the floors, and common areas other than the compartments, to execute the following steps: a storage battery installed in one of the common areas on the second floor or higher stores electricity generated by a distributed power source; a power conditioner installed at a height of 30 cm or more above the floor of the first floor of the building supplies the electricity stored in the storage battery to an electrical load in the building when power supply from the grid power source is stopped; a communication device installed in one of the common areas at a height of 180 cm or more above the floor of the first floor common area operates using electricity supplied by the power conditioner; and an access point installed in each of the compartments at a height of 30 cm or more above the floor of the compartments communicates with the communication device via a communication cable wired at a height near the ceiling of the floor on which it is installed. The computer program according to one embodiment of the present invention is essentially the same invention as the security system, except that it is in a different category, and provides similar actions and effects.

[0012] Next, a security system, a method, and a computer program according to the present embodiment will be described with reference to the drawings. The embodiment described below is merely an example, and the present invention is not limited to the following embodiment. In all the drawings for explaining the embodiments, the same reference numerals are used for components having the same functions, and repeated explanations will be omitted. Furthermore, in this application, "based on XX" means "based on at least XX," and includes cases where it is based on other elements in addition to XX. Furthermore, "based on XX" is not limited to cases where XX is used directly, but also includes cases where it is based on XX that has been calculated or processed. "XX" is any element (for example, any information).

[0013] (Embodiment) (Security System) FIG. 1 is a diagram showing an example of the configuration of a security system according to an embodiment of the present invention. In FIG. 1, the security system is installed in a building BU. An example of a building BU is an apartment building, which has multiple floors. As an example, the explanation will continue with a case where the building BU has two floors, a first floor and a second floor. An apartment building is a single building in which multiple households reside, and includes multiple compartments corresponding to the multiple households. Electricity is supplied to each of the multiple compartments, and the supplied electricity is used by consumers.

[0014] An example of building BU includes sections 50-1 to 50-3 and a common area 60-1 on the first floor, and sections 50-4 to 50-6 and a common area 60-2 on the second floor. Each of common areas 60-1 and 60-2 may include a common corridor (an interior corridor, an exterior corridor). Section 50-1 has access point AP-1, and consumer 30-1 uses electricity in section 50-1. Section 50-2 has access point AP-2, and consumer 30-2 uses electricity in section 50-2. Section 50-3 has access point AP-3, and consumer 30-3 uses electricity in section 50-3. Section 50-4 has access point AP-4, and consumer 30-4 uses electricity in section 50-4. Section 50-5 has access point AP-5, and consumer 30-5 uses electricity in section 50-5. Section 50-6 has access point AP-6, and consumer 30-6 uses electricity in section 50-6. Access point AP-1, access point AP-2, and access point AP-3 are installed at a height H012 of 30 cm or more from the floor of the first floor of building BU.

[0015] The security system includes a storage battery 100, a power conditioner 200, and a communication device 300. The storage battery 100 stores electricity generated by a distributed power source. An example of a distributed power source is a photovoltaic power generation system PV. The storage battery 100 stores electricity generated by a solar cell SC. The storage battery 100 is installed at a height H012 that is greater than the height of a person HU, for example, 180 cm or greater, from the floor on the first floor of the building BU. For example, the storage battery 100 is installed in a common area 60-2 on the second floor of the building BU. The storage battery 100 may be installed directly on the floor or on a stand. Below, as an example, the explanation will continue for a case where the storage battery 100 is installed in the common area 60-2 on the second floor of the building BU. By configuring it in this way, even if a disaster such as a flood occurs and the first floor of the building BU is submerged, the storage battery 100 can be prevented from being submerged.

[0016] The power conditioner 200 is connected to the system power supply, the solar cell CE, and the storage battery 100. The power conditioner 200 converts DC electricity into AC electricity. The power conditioner 200 converts the DC power generated by the solar cell SC into AC power, and stores the AC power in the storage battery 100. The power conditioner 200 determines whether or not power is being supplied from the grid power supply. If the power conditioner 200 determines that power is not being supplied from the grid power supply due to a power outage or the like, the power conditioner 200 supplies the electricity stored in the storage battery 100 to the electrical loads included in the building. The power conditioner 200 is installed at a height H012 that is greater than the height of a person HU, for example, 180 cm or more, from the floor of the first floor of the building BU. For example, the power conditioner 200 is installed at a height near the ceiling of the first floor of the building BU. The following description will be given, as an example, of a case where the power conditioner 200 is installed at a height near the ceiling of the first floor of the building BU, for example, at a height of about several centimeters from the ceiling. For example, the power conditioner 200 is attached to the outer wall of the building BU. By configuring it in this manner, even if a disaster such as a flood occurs and the first floor of the building BU is submerged, the power conditioner 200 can be prevented from being submerged.

[0017] As described above, in the security system, the storage battery 100 and the power conditioner 200 are installed at a height of 180 cm or more from the first floor of the building. Even if a disaster such as a flood occurs and the first floor of the building BU is submerged, the storage battery 100 and the power conditioner 200 can be prevented from being submerged. Therefore, even if a power outage occurs due to a disaster such as a flood and the power supply from the grid power source is stopped, the electricity stored in the storage battery 100 can be supplied to the electrical loads included in the building.

[0018] An example of an electric load is a communication device 300. When a power outage occurs, the communication device 300 operates on electricity supplied by the power conditioner 200. The communication device 300 is connected to each of the access points AP-1 to AP-6 via a LAN (Local Area Network). They are connected by a LAN cable. An example of a LAN cable is one that supports PoE (Power over Ethernet). For example, communication device 300 and access point AP-1 are connected by a LAN cable wired at a height near the ceiling of section 50-1 (height near the ceiling on the first floor of building BU), for example, a height of about several centimeters from the ceiling. For example, communication device 300 and access point AP-2 are connected by a LAN cable wired at a height near the ceiling of section 50-2 (height near the ceiling on the first floor of building BU), for example, a height of about several centimeters from the ceiling. For example, communication device 300 and access point AP-3 are connected by a LAN cable wired at a height near the ceiling of section 50-3 (height near the ceiling on the first floor of building BU), for example, a height of about several centimeters from the ceiling. Even if a disaster such as flooding occurs and the area under the floor of the first floor of Building BU is flooded, the LAN cables can be prevented from being submerged. Communication can continue via each of Access Points AP-1 to AP-3, so the security functions of the building can be maintained in the event of a disaster.

[0019] Each of access points AP-1 to AP-6 operates on electricity supplied by communication device 300. Residents (consumers 30-1 to 30-6) in each of sections 50-1 to 50-6 can communicate with the outside world via access point AP-1 to access point AP-6, respectively. For example, residents (consumers 30-1 to 30-6) may communicate via access point AP-1 to access point AP-6 using a wireless communication method such as wireless LAN or LTE (registered trademark). This allows the security functions of the building to be maintained in the event of a disaster.

[0020] (Security system operation) 2 is a flowchart showing an example of the operation of the security system according to this embodiment. In the security system, the storage battery 100 and the power conditioner 200 are installed at a height of 180 cm or more from the first floor of a building, and the access points AP-1, AP-2, and AP-3 are installed at a height H012 of 30 cm or more from the first floor of the building BU. The communication device 300 and each of the access points AP-1 to AP-3 are connected by LAN cables wired at a height of about several centimeters from the ceiling.

[0021] (Step S1-1) In the security system, the power conditioner 200 determines whether or not the power supply from the system power supply has stopped. (Step S2-1) In the security system, when it is determined in step S1-1 that the power supply from the grid power supply has stopped, the power conditioner 200 supplies electricity stored in the storage battery 100 to the communication device 300. (Step S3-1) In the security system, the power conditioner 200 determines whether or not the power supply from the grid power supply has resumed. If the power supply from the grid power supply has not resumed, the process returns to step S2-1. (Step S4-1) If it is determined in step S3-1 that the power supply from the power grid has resumed, the security system supplies electricity from the power grid to the communication device 300. Then, the process returns to step S1-1.

[0022] In the above-described embodiment, the building BU has two floors, a first floor and a second floor, but the present invention is not limited to this example. For example, the building BU may have three or more floors. In the above-described embodiment, the storage battery 100 and the power conditioner 200 are installed at a height of 180 cm or more from the first floor of a building, but this is not limiting. For example, they may be installed at a height above the water level expected in the event of a flood, for example, 30 cm or more from the floor of each of the first floor sections 50-1 to 50-3. In the above-described embodiment, the case where the communication device 300 supplies electricity stored in the storage battery 100 to each of the access points AP-1 to AP-6 has been described, but this is not limiting. For example, the storage battery 100 may supply power to each of the access points AP-1 to AP-6. In the above-described embodiment, the security system may further include at least one of a fire alarm, a smart lock, a burglar prevention sensor, an intercom, an emergency light, and an emergency outlet. In this case, when the power supply from the grid power supply is stopped, the power conditioner 200 may supply electricity stored in the storage battery 100 to at least one of the fire alarm, the smart lock, the burglar prevention sensor, the intercom, the emergency light, and the emergency outlet included in the building BU.

[0023] The security system according to this embodiment includes a storage battery 100 that stores electricity generated by a distributed power source, and a power conditioner 200 that supplies the electricity stored in the storage battery 100 to an electrical load included in the building BU when power supply from the grid power source is stopped. The storage battery 100 and the power conditioner 200 are installed at a height of 180 cm or more from the first floor of the building BU. With this configuration, the security system includes a storage battery 100 that stores electricity generated by the distributed power source, and a power conditioner that supplies the electricity stored in the storage battery 100 to electrical loads included in the building BU when power supply from the grid power source is stopped. Because the storage battery 100 and the power conditioner 200 are installed at a height of 180 cm or more above the first floor of the building BU, they will not be submerged even if a disaster such as a flood occurs and the building BU is submerged several tens of cm above the first floor. Even in the event of a disaster, the electricity stored in the storage battery 100 can be supplied to electrical loads included in the building, so the security functions of the building BU can be maintained in the event of a disaster.

[0024] The security system further includes a communication device 300 that operates on electricity supplied by the power conditioner 200. With this configuration, the communication equipment can be operated using electricity supplied by the power conditioner 200, enabling communication with the outside world. This allows the security functions of the building to be maintained in the event of a disaster. In the security system, the communication device 300 supplies power to each of the access points AP-1 to AP-6 installed in each of a plurality of customers included in the building BU. With this configuration, in the security system, communication device 300 can supply power to each of access points AP-1 to AP-6 installed in each of multiple consumers included in building BU, allowing residents to communicate with the outside world via each of access points AP-1 to AP-6. This makes it possible to maintain the security functions of the building in the event of a disaster.

[0025] In the security system, each of the multiple access points AP-1 to AP-6 is installed at a height of 30 cm or more from the first floor of the building BU. With this configuration, each of the multiple access points in the security system can be installed at a height of 30 cm or more above the first floor of the building. Even in the event of flooding, as long as the water level is less than 30 cm above the first floor of the building, the access points will not be submerged, allowing residents to communicate with the outside world through the access points. This allows the building's security functions to be maintained in the event of a disaster.

[0026] (Modification 1 of the embodiment) 3 is a diagram showing an example of the configuration of a security system according to Modification 1 of the embodiment. The security system differs from the security system according to the embodiment in that it includes a surveillance camera CA, an automatic door AD, a control unit 400, and an access point AP-A. An example of a surveillance camera CA is installed at the entrance of a building BU and monitors people entering and exiting the building BU. The surveillance camera CA is connected to a communication device 300. The communication device 300 supplies power to the surveillance camera CA. The communication device 300 acquires either or both of images and videos captured by the surveillance camera CA and stores the acquired images and videos. The communication device 300 may transmit either or both of the acquired images and videos to a surveillance server (not shown). In the security system, the communication device 300 can supply power to the surveillance camera CA, making it possible for the surveillance camera CA to monitor the inside of a building.

[0027] An example of the automatic door AD is installed at the entrance of the building BU. The automatic door AD is connected to the control unit 400. The control unit 400 operates using electricity supplied by the power conditioner 200 and controls the automatic door AD. For example, the automatic door may be kept closed to prevent people from entering the building BU from outside. An example of access point AP-A is installed in common area 60-1 of building BU. In the security system, access point AP-A is installed at a predetermined height from the first floor of building BU. For example, access point AP-A may be installed at a height of approximately 10 cm to 50 cm from the first floor of building BU. Access point AP-A notifies a management server (not shown) that it is available for use. With this configuration, in the security system, access point AP-A can be installed at a predetermined height above the first floor of the building. In the event of flooding, the management server monitors whether access point AP-A is available. If access point AP-A becomes unavailable, it can be determined that the water level has reached a predetermined height above the first floor of the building.

[0028] (Security system operation) FIG. 4 is a flowchart showing an example of the operation of the security system according to the first modification of the embodiment. (Step S1-2) In the security system, the power conditioner 200 determines whether or not the power supply from the system power supply has stopped. (Step S2-2) In the security system, when it is determined in step S1-2 that the power supply from the grid power supply has stopped, the power conditioner 200 supplies electricity stored in the storage battery 100 to the communication device 300. (Step S3-2) In the security system, a power conditioner 200 supplies electricity stored in a storage battery 100 to a surveillance camera CA.

[0029] (Step S4-2) In the security system, the power conditioner 200 supplies electricity stored in the storage battery 100 to the control unit 400. (Step S5-2) In the security system, the control unit 400 operates the automatic door AD. (Step S6-2) In the security system, the power conditioner 200 determines whether or not the power supply from the grid power supply has resumed. If the power supply from the grid power supply has not resumed, the process returns to step S2-2. (Step S7-2) If it is determined in step S6-2 that the power supply from the power grid has resumed, the security system supplies electricity from the power grid to the communication device 300. Then, the process returns to step S1-2.

[0030] In the first modification of the embodiment, the security system is described as having one access point AP-A installed at a predetermined height from the floor of the building BU, but this is not limiting. For example, the security system may be configured to have multiple access points AP-A. In this case, the security system has multiple access points AP-A installed at different heights from the floor of the building BU, and in the event of flood damage, the management server monitors whether each of the multiple access points AP-A is available for use. By configuring it in this way, if one of the multiple access points AP-A becomes unusable, it is possible to determine whether the water level has reached a height above the first floor of the building by identifying the height at which the unusable access point AP-A is installed. According to the security system of the first modification of the embodiment, the communication device 300 supplies power to the surveillance camera CA included in the building BU. With this configuration, in the security system, the communication device 300 can supply power to the surveillance camera CA included in the building BU, allowing the surveillance camera CA to monitor the inside of the building BU. This makes it possible to maintain the security function of the building BU in the event of a disaster.

[0031] The security system further includes a control unit 400 that operates the automatic door AD using electricity supplied by the power conditioner 200. With this configuration, the security system can further include a control unit 400 that operates the automatic door AD using electricity supplied by the power conditioner 200, thereby enabling the automatic door AD to be operated. This allows the security functions of the building BU to be maintained in the event of a disaster.

[0032] (Modification 2 of the embodiment) 5 is a diagram showing an example of the configuration of a security system according to Modification 2 of the embodiment. The security system differs from the security system according to the embodiment in that it includes a main distribution board 500. The main distribution board 500 is a concentrator that accommodates and centrally manages all communication lines leading to the outside. All telephone lines, optical fiber lines, and subscriber lines such as CATV that connect the inside and outside of the building are routed through the main distribution board 500 to each room and each floor. An example of the main distribution board 500 is installed at a height H012 that is greater than the height of a person HU, for example, 180 cm or more, from the floor on the first floor of the building BU. For example, the main distribution board 500 is installed in the common area 60-2 on the second floor of the building BU. The main distribution board 500 may be installed directly on the floor or on a stand. Below, as an example, the explanation will continue for the case where the main distribution board 500 is installed in the common area 60-2 on the second floor of the building BU. By configuring it in this way, even if a disaster such as a flood occurs and the first floor of the building BU is submerged, the main distribution board 500 can be prevented from being submerged.

[0033] (Security system operation) FIG. 6 is a flowchart showing an example of the operation of the security system according to the second modification of the embodiment. (Step S1-3) In the security system, the power conditioner 200 determines whether or not the power supply from the system power supply has stopped. (Step S2-3) In the security system, the power conditioner 200 supplies electricity stored in the storage battery 100 to the communication device 300 when it is determined in step S1-3 that the power supply from the grid power supply has stopped.

[0034] (Step S3-3) In the security system, the power conditioner 200 supplies electricity stored in the storage battery 100 to the main distribution board 500. (Step S4-3) In the security system, the power conditioner 200 determines whether or not the power supply from the grid power supply has resumed. If the power supply from the grid power supply has not resumed, the process returns to step S2-3. (Step S5-3) If it is determined in step S4-3 that the power supply from the power grid has resumed, the security system supplies electricity from the power grid to the communication device 300. Then, the process returns to step S1-3.

[0035] In the second modification of the embodiment described above, the main distribution board 500 is installed at a height of 180 cm or more from the first floor of the building, but this is not limiting. For example, the main distribution board 500 may be installed at a height above the expected water level in the event of a flood, for example, 30 cm or more from the floor of each of the first floor sections 50-1 to 50-3. In the second modification of the embodiment described above, the case where the communication device 300 and the main distribution board 500 are separate devices has been described, but the present invention is not limited to this example. For example, the communication device 300 may be housed within the main distribution board 500. In the second modification of the above-described embodiment, a TV booster may be installed in the main distribution board 500. A TV booster is a high-frequency amplifier compatible with terrestrial waves (UHF) and satellite waves (BSCS) used for television reception. The TV booster compensates for distribution loss and cable loss, maintains signal strength within recommended levels, and prevents degradation of signal quality beyond the installation point. The power conditioner 200 supplies power to the TV booster installed in the main distribution board 500. This configuration ensures reception of broadcast radio waves. According to the security system according to the second modification of the embodiment, the security system according to the embodiment may further include a main distribution board 500 that supplies electricity supplied by the power conditioner 200 to the communication equipment. With this configuration, in the security system, the main distribution board 500 can supply power to the communication equipment using electricity supplied by the power conditioner 200, so even in the event of a disaster, the communication equipment can be operated using electricity supplied by the power conditioner 200, enabling communication with the outside world. This allows the security functions of the building to be maintained in the event of a disaster.

[0036] In a security system, the power conditioner 200 may power a TV booster. With this configuration, the power conditioner 200 in the security system can supply power to a TV booster. The use of broadcast radio waves makes it possible to grasp the external situation. This allows the building's security functions to be maintained in the event of a disaster.

[0037] The above describes the embodiments and their modifications. However, these embodiments and their modifications are presented as examples and are not intended to limit the scope of the invention. These embodiments and their modifications can be embodied in various other forms, and various omissions, substitutions, modifications, and combinations can be made without departing from the spirit of the invention. For example, Modification 1 of Embodiment 1 and Modification 2 of Embodiment 1 can be combined. These embodiments and their modifications are intended to fall within the scope and spirit of the invention, as well as the scope of the invention and its equivalents as set forth in the claims.

[0038] As mentioned above, the above-described power conditioner 200 is realized by including a computer. In this case, a program for realizing the functions of each functional block is recorded on a computer-readable recording medium. The program recorded on this recording medium may be read into a computer system and executed by a CPU to realize the functions. The "computer system" here includes an OS (Operating System) and hardware such as peripheral devices. Furthermore, "computer-readable recording media" refers to portable media such as flexible disks, optical magnetic disks, ROMs, CD-ROMs, etc. "Computer-readable recording media" also includes storage devices such as hard disks built into computer systems.

[0039] Furthermore, the term "computer-readable recording medium" may include a medium that dynamically stores a program for a short period of time, such as a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line. Furthermore, the "computer-readable recording medium" may also include something that stores a program for a certain period of time, such as volatile memory within a computer system that is a server or client. The program may be for realizing part of the above-described functions, or may be capable of realizing the above-described functions in combination with a program already stored in the computer system. The program may be implemented using a programmable logic device, such as a field programmable gate array (FPGA).

[0040] The above-described power conditioner 200 has an internal computer. Each process of the above-described power conditioner 200 is stored in the form of a program on a computer-readable recording medium, and the computer reads and executes the program to perform the above-described process. Here, the computer-readable recording medium refers to a magnetic disk, a magneto-optical disk, a CD-ROM, a DVD-ROM, a semiconductor memory, or the like. Alternatively, the computer program may be distributed to a computer via a communication line, and the computer that receives the program may execute the program. The program may also be for realizing part of the above-mentioned functions. Furthermore, the above-mentioned functions may be realized in combination with a program already recorded in the computer system, that is, a so-called differential file (differential program).
