Technical Field

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

Background Art

[0002] In addition to AC power supplied from the utility power supply, a technique for supplying power to an electrical load using a distributed power source such as a storage battery mounted on a photovoltaic power generation device is known. Regarding the technique of supplying power to an electrical load using a distributed power source, it is not necessary to adjust the voltage, frequency, and phase with the utility power supply, enabling a reduction in the introduction cost, and enabling at least a part of the operation of the electrical load even when the power supply from the utility power supply stops (see, for example, Patent Document 1).

[0003] According to this technique, the power supply system includes a DC power supply device and an electrical load. The DC power supply device is supplied with power from an independent power source that is a separate system from the utility power supply and outputs DC power. The electrical load is connected to a first power supply line supplied with power from the utility power supply. Also, the electrical load is connected to a second power supply line supplied with 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.

Summary of the Invention

Problems to be Solved by the Invention

[0005] When a disaster such as a flood occurs and AC power is no longer supplied from the utility power supply to a building due to a power outage, power is supplied to the electrical load using a distributed power source. However, if the storage battery mounted on the photovoltaic power generation device is submerged, it becomes impossible to supply power to the electrical load using the distributed power source. When the AC power supply from the utility grid stops due to a power outage and the distributed power source cannot supply power to the electrical load, the security function of the building will be disabled. An object of the present invention is to provide a security system, method, and program capable of maintaining the security function of a building when a disaster occurs.

Means for Solving the Problems

[0006] (1) To solve the above problems, an embodiment of the present invention includes a storage battery that stores electricity generated by a distributed power source, and a power conditioner that supplies the electricity stored in the storage battery to an electrical load included in a building when power supply from the utility grid stops. The storage battery and the power conditioner are installed at a height of 180 cm or more from the floor of the first floor of the building, and it is a security system.

[0007] According to the security system according to this embodiment, the security system includes a storage battery that stores electricity generated by a distributed power source. An example of the distributed power source is solar power generation. In this case, the storage battery stores the electricity generated by solar power generation. The security system includes a power conditioner that supplies the electricity stored in the storage battery to an electrical load included in a building when power supply from the utility grid stops. The power conditioner supplies the electricity stored in the storage battery to the electrical load when power supply from the utility grid stops due to a power outage or the like. In the security system, the storage battery and the power conditioner are installed at a height of 180 cm or more from the floor of the first floor of the building.

[0008] In this way, the security system includes a storage battery that stores electricity generated by a distributed power source, and a power conditioner that supplies the electricity stored in the storage battery to an electrical load included in a building when power supply from the utility grid stops. Since the storage battery and the power conditioner are installed at a height of 180 cm or more from the floor on the first floor of the building, even if a disaster such as a flood occurs and the first floor of the building is flooded by several tens of centimeters, they will not be submerged. Even when a disaster occurs, since the electricity stored in the storage battery can be supplied to the electrical load included in the building, the security function of the building can be maintained when a disaster occurs.

[0009] (2) In one embodiment of the present invention, in the security system described above, the security system may further include a communication device that operates with electricity supplied by the power conditioner. By configuring in this way, since the communication device can be operated with electricity supplied by the power conditioner, communication with the outside becomes possible. Therefore, the security function of the building can be maintained when a disaster occurs.

[0010] (3) In one embodiment of the present invention, in the security system described above, the communication device may supply power to access points installed at each of a plurality of customers included in the building. By configuring in this way, in the security system, since the communication device can supply power to the access points installed at each of a plurality of customers included in the building, the occupants (customers) can communicate with the outside through the access points. Therefore, the security function of the building can be maintained when a disaster occurs.

[0011] (4) In one embodiment of the present invention, in the security system described above, each of the plurality of access points may be installed at a height of 30 cm or more from the floor on the first floor of the building. By configuring in this way, in the security system, each of the plurality of access points can be installed at a height of 30 cm or more from the floor of the first floor of the building. Even when a flood occurs, if the water level is less than 30 cm from the floor of the first floor of the building, the access point will not be submerged, so that the residents can communicate with the outside through the access point. Therefore, the security function of the building can be maintained when a disaster occurs.

[0012] (5) In one embodiment of the present invention, in the security system described above, the communication device may supply power to a surveillance camera included in the building. By configuring in this way, in the security system, the communication device can supply power to the surveillance camera included in the building, so that it is possible to monitor the inside of the building with the surveillance camera. Therefore, the security function of the building can be maintained when a disaster occurs.

[0013] (6) In one embodiment of the present invention, in the security system described above, the security system may further include a control unit that operates an automatic door with the electricity supplied by the power conditioner. By configuring in this way, the security system can further include a control unit that operates an automatic door with the electricity supplied by the power conditioner, so that the automatic door can be operated. Therefore, the security function of the building can be maintained when a disaster occurs.

[0014] (7) In one embodiment of the present invention, in the security system described above, the security system may further include a main wiring board that supplies power to communication facilities with the electricity supplied by the power conditioner. By configuring in this way, in the security system, the main wiring board can supply power to the communication facilities with the electricity supplied by the power conditioner, so that even when a disaster occurs, the communication facilities can be operated. Therefore, communication with the outside becomes possible. The security function of the building can be maintained when a disaster occurs.

[0015] (8) In one embodiment of the present invention, in the security system described above, the power conditioner may supply power to the TV booster. By configuring in this way, in the security system, the power conditioner can supply power to the TV booster. Since broadcast radio waves can be utilized, it becomes possible to grasp the external situation. Therefore, when a disaster occurs, the security function of the building can be maintained.

[0016] (9) One embodiment of the present invention includes a step of accumulating electricity generated by a distributed power source in a storage battery, and a step of the power conditioner supplying the electricity accumulated in the storage battery to an electrical load included in a building when power supply from the grid power source stops, wherein the storage battery and the power conditioner are installed at a height of 180 cm or more from the floor on the first floor of the building. According to the information processing method according to one embodiment of the present invention, it is substantially the same invention except that the category is different from that of the security system, and has the same operations and effects.

[0017] (10) One embodiment of the present invention is a computer program that causes a computer to execute a step of determining whether power supply from the grid power source has stopped, and a step of supplying the electricity accumulated in a storage battery that accumulates electricity generated by a distributed power source to communication equipment included in a building when it is determined in the determining step that power supply from the grid power source has stopped. By configuring in this way, when power supply from the grid power source stops, the computer of the power conditioner can supply the electricity accumulated in a storage battery that accumulates electricity generated by a distributed power source to communication equipment included in a building, so that communication with the outside becomes possible. Therefore, when a disaster occurs, the security function of the building can be maintained.

Modes for Carrying Out the Invention

[0020] Next, a security system, method, and computer program according to the present embodiment will be described with reference to the drawings. The embodiments described below are merely examples, and the embodiments to which the present invention is applied are not limited to the following embodiments. In all the drawings for explaining the embodiments, those having the same function are denoted by the same reference numerals, and repeated explanations are omitted. In addition, “based on XX” as used in the present application means “based on at least XX”, and includes cases where it is based on another element in addition to XX. Also, “based on XX” is not limited to the case where XX is directly used, and includes cases where it is based on something obtained by performing an operation or processing on XX. “XX” is an arbitrary element (for example, arbitrary information).

[0021] (Embodiment) (Security System) FIG. 1 is a diagram showing a configuration example 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 the building BU is an apartment building, which has a plurality of floors. As an example, the case where the building BU has two floors, the first floor and the second floor, will be continued to be described. The apartment building has a plurality of households living in one building and includes a plurality of compartments corresponding to the plurality of households. Electricity is supplied to each of the plurality of compartments, and the consumer uses the supplied electricity.

[0022] An example of the building BU includes compartments 50-1 to 50-3 and a common area 60-1 on the first floor, and compartments 50-4 to 50-6 and a common area 60-2 on the second floor. Each of the common area 60-1 and the common area 60-2 may include a common corridor (inner corridor, outer corridor). The compartment 50-1 is provided with an access point AP-1, and in the compartment 50-1, the consumer 30-1 uses electricity. The compartment 50-2 is provided with an access point AP-2, and in the compartment 50-2, the consumer 30-2 uses electricity. The compartment 50-3 is provided with an access point AP-3, and in the compartment 50-3, the consumer 30-3 uses electricity. The compartment 50-4 is provided with an access point AP-4, and in the compartment 50-4, the consumer 30-4 uses electricity. The compartment 50-5 is provided with an access point AP-5, and in the compartment 50-5, the consumer 30-5 uses electricity. The compartment 50-6 is provided with an access point AP-6, and in the compartment 50-6, the consumer 30-6 uses electricity. The access point AP-1, the access point AP-2, and the access point AP-3 are installed at a height of 30 cm or more from the floor of the first floor of the building BU.

[0023] 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 the distributed power source is a solar 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 higher than the height of the person HU, for example, at a height of 180 cm or more, H012 or more, from the floor on the first floor of the building BU. For example, the storage battery 100 is installed in the common area 60-2 on the second floor of the building BU. The storage battery 100 may be directly installed on the floor or installed on a pedestal. Hereinafter, as an example, the case where the storage battery 100 is installed in the common area 60-2 on the second floor of the building BU will be continued to be described. By configuring in this way, even if a disaster such as a flood occurs and the first floor part of the building BU is flooded, it is possible to prevent the storage battery 100 from being flooded.

[0024] The power conditioner 200 is connected to the utility power supply, the solar cell CE, and the storage battery 100. The power conditioner 200 converts direct current electricity into alternating current electricity. The power conditioner 200 converts the direct current power generated by the solar cell SC into alternating current power, and stores the converted alternating current power in the storage battery 100. The power conditioner 200 determines whether or not it is being powered from the utility power supply. When the power conditioner 200 determines that it is not being powered from the utility power supply due to a power outage or the like, it 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 higher than the height of the person HU, for example, at a height of 180 cm or more, H012 or more, from the floor on the first floor of the building BU. For example, the power conditioner 200 is installed at a height near the ceiling on the first floor of the building BU. Hereinafter, as an example, the case where the power conditioner 200 is installed at a height near the ceiling on the first floor of the building BU, for example, at a height of about several centimeters from the ceiling, will be continued to be described. For example, the power conditioner 200 is attached to the outer wall of the building BU. By configuring in this way, even if a disaster such as a flood occurs and the first floor part of the building BU is flooded, it is possible to prevent the power conditioner 200 from being flooded.

[0025] 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 floor on the first floor of the building. Even if a disaster such as a flood occurs and the first floor part of the building BU is flooded, it is possible to prevent the storage battery 100 and the power conditioner 200 from being flooded. Therefore, even if a power outage occurs due to a disaster such as a flood and the power supply from the utility power source stops, the electricity stored in the storage battery 100 can be supplied to the electrical loads included in the building.

[0026] An example of the electrical load is the communication device 300. The communication device 300 operates on electricity supplied by the power conditioner 200 when a power outage occurs. The communication device 300 is connected to each of the access points AP-1 to AP-6 by a LAN (Local Area Network) cable. An example of the LAN cable is one compatible with Power over Ethernet (PoE) power supply. For example, the communication device 300 and the access point AP-1 are connected by a LAN cable wired at a height near the ceiling of section 50-1 (the height near the ceiling on the first floor of the building BU), for example, at a height of about several centimeters from the ceiling. For example, the communication device 300 and the access point AP-2 are connected by a LAN cable wired at a height near the ceiling of section 50-2 (the height near the ceiling on the first floor of the building BU), for example, at a height of about several centimeters from the ceiling. For example, the communication device 300 and the access point AP-3 are connected by a LAN cable wired at a height near the ceiling of section 50-3 (the height near the ceiling on the first floor of the building BU), for example, at a height of about several centimeters from the ceiling. Even if a disaster such as a flood occurs and the underfloor part on the first floor of the building BU is flooded, it is possible to prevent the LAN cable from being flooded. Since communication via each of the access points AP-1 to AP-3 can be continued, the security function of the building can be maintained when a disaster occurs.

[0027] Each of the access points AP-1 to AP-6 operates electrically powered by the communication device 300. Each resident (customer 30-1 to customer 30-6) in each of the sections 50-1 to 50-6 can communicate with the outside through each of the access points AP-1 to AP-6, respectively. For example, the residents (customers 30-1 to 30-6) may communicate via wireless communication methods such as wireless LAN and LTE (registered trademark) through each of the access points AP-1 to AP-6. Therefore, the security function of the building can be maintained in case of a disaster.

[0028] (Operation of the security system) FIG. 2 is a flowchart showing an example of the operation of the security system according to the present 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 floor on the first floor of the building, and the access points AP-1, AP-2, and AP-3 are installed at a height of 30 cm or more, H012, from the floor on 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 a LAN cable wired at a height of about several centimeters from the ceiling.

[0029] (Step S1-1) In the security system, the power conditioner 200 determines whether the power supply from the utility power has stopped. (Step S2-1) In the security system, when the power conditioner 200 determines in step S1-1 that the power supply from the utility power has stopped, the power conditioner 200 supplies the 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 the power supply from the utility power has resumed. If the power supply from the utility power has not resumed, the process returns to step S2-1. (Step S4-1) When it is determined in step S3-1 that the power supply from the utility power supply has resumed, the security system supplies the electricity from the utility power supply to the communication device 300. Then, the process returns to step S1-1.

[0030] In the above-described embodiment, the case where the building BU has two floors, the first floor and the second floor, has been described, 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 case where the storage battery 100 and the power conditioner 200 are installed at a height of 180 cm or more from the floor of the first floor of the building has been described, but the present invention is not limited to this example. For example, it may be 30 cm or more from the floor of each of the sections 50-1 to 50-3 on the first floor, that is, above the water level assumed in the event of a flood. In the above-described embodiment, the case where the communication device 300 supplies the electricity stored in the storage battery 100 to each of the access points AP-1 to AP-6 has been described, but the present invention is not limited to this example. For example, the storage battery 100 may supply the electricity 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 security sensor, an intercom, an emergency light, and an emergency outlet. In this case, when the power supply from the utility power supply stops, the power conditioner 200 may supply the electricity stored in the storage battery 100 to at least one of the fire alarm, the smart lock, the security sensor, the intercom, the emergency light, and the emergency outlet included in the building BU.

[0031] According to the security system according to the present embodiment, the security system includes a storage battery 100 that stores the electricity generated by the distributed power source, and a power conditioner 200 that supplies the electricity stored in the storage battery 100 to the electrical loads included in the building BU when the power supply from the utility power supply stops. The storage battery 100 and the power conditioner 200 are installed at a height of 180 cm or more from the floor of the first floor of the building BU. By configuring in this way, the security system includes a storage battery 100 that stores electricity generated by distributed power sources, and a power conditioner that supplies the electricity stored in the storage battery 100 to electrical loads included in the building BU when the power supply from the utility grid stops. Since the storage battery 100 and the power conditioner 200 are installed at a height of 180 cm or more from the floor on the first floor of the building BU, even when a disaster such as a flood occurs and the first floor of the building BU is flooded by several tens of centimeters, they will not be submerged. Even when a disaster occurs, since the electricity stored in the storage battery 100 can be supplied to the electrical loads included in the building, the security function of the building BU can be maintained when a disaster occurs.

[0032] The security system further includes a communication device 300 that operates with the electricity supplied by the power conditioner 200. By configuring in this way, since the communication device can be operated with the electricity supplied by the power conditioner 200, communication with the outside becomes possible. Therefore, the security function of the building can be maintained when a disaster occurs. 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. By configuring in this way, in the security system, since the communication device 300 can supply 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, the residents can communicate with the outside through each of the access points AP-1 to AP-6. Therefore, the security function of the building can be maintained when a disaster occurs.

[0033] In the security system, each of the plurality of access points AP-1 to AP-6 is installed at a height of 30 cm or more from the floor on the first floor of the building BU. By configuring it in this way, in the security system, each of the plurality of access points can be installed at a height of 30 cm or more from the floor of the first floor of the building. Even when a flood occurs, if the water level is less than 30 cm from the floor of the first floor of the building, the access point will not be submerged, so that the occupants can communicate with the outside through the access point. Therefore, the security function of the building can be maintained when a disaster occurs.

[0034] (Modification Example 1 of the Embodiment) FIG. 3 is a diagram showing a configuration example of a security system according to Modification Example 1 of the embodiment. The security system is different 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 in the security system according to the embodiment. An example of the surveillance camera CA is installed at the entrance and exit of the building BU and monitors the people entering and leaving the building BU. The surveillance camera CA is connected to the communication device 300. The communication device 300 supplies power to the surveillance camera CA. The communication device 300 acquires either one or both of the images and videos captured by the surveillance camera CA and stores either one or both of the acquired images and videos. The communication device 300 may transmit either one or both of the acquired images and videos to a surveillance server (not shown). In the security system, since the communication device 300 can supply power to the surveillance camera CA, it is possible to monitor the inside of the building with the surveillance camera CA.

[0035] An example of the automatic door AD is installed at the entrance and exit of the building BU. The automatic door AD is connected to the control unit 400. The control unit 400 operates with the electricity supplied by the power conditioner 200 and controls the automatic door AD. For example, the automatic door may be kept closed so that people do not intrude into the building BU from the outside. An example of the access point AP-A is installed in the common area 60-1 of the building BU. In the security system, the access point AP-A is installed at a predetermined height from the floor on the first floor of the building BU. For example, the access point AP-A may be installed at a height of about 10 cm to 50 cm from the floor on the first floor of the building BU. The access point AP-A notifies a management server (not shown) that it is available for use. By configuring in this way, in the security system, the access point AP-A can be installed at a predetermined height from the floor of the building. When a flood occurs, the management server monitors whether the access point AP-A is available for use. If the access point AP-A becomes unavailable, it can be determined that the water level has reached a predetermined height from the floor on the first floor of the building.

[0036] (Operation of the security system) FIG. 4 is a flowchart showing an example of the operation of the security system according to Modification 1 of the embodiment. (Step S1-2) In the security system, the power conditioner 200 determines whether the power supply from the utility power has stopped. (Step S2-2) In the security system, when the power conditioner 200 determines in step S1-2 that the power supply from the utility power has stopped, the power conditioner 200 supplies the electricity stored in the storage battery 100 to the communication device 300. (Step S3-2) In the security system, the power conditioner 200 supplies the electricity stored in the storage battery 100 to the surveillance camera CA.

[0037] (Step S4-2) In the security system, the power conditioner 200 supplies the 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 the power supply from the utility power supply has resumed. If the power supply from the utility power supply has not resumed, the process returns to step S2-2. (Step S7-2) When the security system determines in step S6-2 that the power supply from the utility power supply has resumed, the security system supplies power from the utility power supply to the communication device 300. Then, the process returns to step S1-2.

[0038] In Modification Example 1 of the embodiment, the case where the security system includes one access point AP-A installed at a predetermined height from the floor of the building BU has been described, but the present invention is not limited to this example. For example, the security system may include a plurality of access points AP-A. In this case, the security system includes a plurality of access points AP-A installed at different heights from the floor of the building BU, and when a flood occurs, the management server monitors whether each of the plurality of access points AP-A is available. By configuring in this way, if any one of the plurality of access points AP-A becomes unusable, by specifying the height at which the unusable access point AP-A is installed, it is possible to grasp whether the water level has reached a certain height from the floor of the first floor of the building. According to the security system according to Modification Example 1 of the embodiment, in the security system according to the embodiment, the communication device 300 supplies power to the surveillance camera CA included in the building BU. By configuring in this way, in the security system, since the communication device 300 can supply power to the surveillance camera CA included in the building BU, it is possible to monitor the inside of the building BU with the surveillance camera CA. Therefore, the security function of the building BU can be maintained when a disaster occurs.

[0039] The security system further includes a control unit 400 that operates the automatic door AD with the 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 with electricity supplied by the power conditioner 200, and can therefore operate the automatic door AD. This makes it possible to maintain the security function of the building BU in the event of a disaster.

[0040] (Modification 2 of the embodiment) 5 is a diagram showing a configuration example 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 a main distribution board 500 is provided in addition to the security system according to the embodiment. The main distribution board 500 is a concentrator that houses 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 wiring board 500 is installed at a height H012, for example, 180 cm or more, from the floor of the first floor of the building BU, which is higher than the height of a person HU. For example, the main wiring board 500 is installed in the common area 60-2 on the second floor of the building BU. The main wiring board 500 may be installed directly on the floor or on a stand. Below, as an example, the case where the main wiring board 500 is installed in the common area 60-2 on the second floor of the building BU will be described. By configuring in this way, even if a disaster such as a flood occurs and the first floor of the building BU is submerged, the main wiring board 500 can be prevented from being submerged.

[0041] (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 power grid has stopped. (Step S2-3) In the security system, when the power conditioner 200 determines that the power supply from the utility power supply has stopped in step S1-3, it supplies the electricity stored in the storage battery 100 to the communication device 300.

[0042] (Step S3-3) In the security system, the power conditioner 200 supplies the 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 the power supply from the utility power supply has resumed. If the power supply from the utility power supply has not resumed, it returns to step S2-3. (Step S5-3) When the security system determines that the power supply from the utility power supply has resumed in step S4-3, it supplies the electricity from the utility power supply to the communication device 300. Then, it returns to step S1-3.

[0043] In Modification Example 2 of the above-described embodiment, the case where the main distribution board 500 is installed at a height of 180 cm or more from the floor on the first floor of the building has been described, but the present invention is not limited to this example. For example, it may be 30 cm or more from each floor of Section 50-1 to Section 50-3 on the first floor, which is above the water level assumed in the event of a flood. In Modification Example 2 of the above-described embodiment, 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 in the main distribution board 500. In Modification Example 2 of the above-described embodiment, a TV booster may be installed in the main distribution board 500. The TV booster is a high-frequency amplifier corresponding to terrestrial waves (UHF) or satellite waves (BSCS) used in television reception. The TV booster compensates for distribution loss and cable loss, maintains the signal strength within the recommended level value, and prevents deterioration of the signal quality after the installation location.
