The light emitted by the device 1 is usually an electromagnetic wave having a wavelength that can be visually recognized by a person (that is, visible light), but may include electromagnetic waves other than visible light, such as infrared rays and radio waves.

As a modified example of the above configuration, the disaster prevention system may include, for example, a set of one or more devices 1, a contactless power feeder 2, and an emergency alert information receiving device 4 (hereinafter, referred to as an emergency alert device group). ) May be provided in two or more sets (Modification 1). In Modification 1, two or more emergency alert device groups are arranged, for example, in a building such as a house or in a room such as an office building.

As another modification, the disaster prevention system may not include the emergency alert information receiving device 4 (Modification 2). In the second modification, each of the one or more devices 1 receives the emergency alert information transmitted from the emergency alert information transmitter 3.

Moreover, as another modification, the disaster prevention system may include two or more non-contact power feeders 2 (Modification 3). In Modified Example 3, the two or more devices 1 and the two or more non-contact power feeders 2 correspond one-to-one, and each of the two or more devices 1 is connected to the non-contact power feeder 2 corresponding to the device 1. Receive power.

Further, as still another modification, the disaster prevention system may not include the contactless power feeder 2 (Modification 4). In the modified example 4, each of the two or more devices 1 includes, for example, a battery, and operates with electric power from the battery. Alternatively, when the article is an electric device, each of the two or more devices 1 may be operated by being supplied with electric power from the electric device to which the device 1 is attached.

Further, as another modification, each of two or more devices 1 capable of receiving power from the contactless power feeder 2 may include a battery (Modification 5). In Modified Example 5, each device 1 operates by using one or more kinds of power supplied from the contactless power feeder 2 or battery power.

In addition, in each of this embodiment and each of Modifications 1 to 5, the number of the non-contact power feeders 2 may be two or more. In such a case, each of the two or more non-contact power feeders 2 may perform non-contact power feeding to the one or two or more devices 1. In other words, one device 1 may receive power from each of two or more contactless power feeders 2. Alternatively, for example, the number of devices 1 is two or more, and the devices 1 and the non-contact power feeders 2 have a one-to-one correspondence, and one device supplies power only from one corresponding non-contact power feeder 2. You can accept it.

Further, the number of emergency alert information receiving devices 4 may be two or more. Further, the one or more non-contact power feeders 2 may perform the non-contact power feeding also to the one or more emergency warning information receiving devices 4.

Next, detailed operation will be described. The emergency alert information receiving device 4 can communicate with one or more of the devices 1 by using a short-range wireless communication such as Bluetooth (registered trademark) or Zigbee (registered trademark). Alternatively, the emergency alert information receiving device 4 may communicate with one or more devices 1 via a network such as a wireless LAN, or may broadcast to one or more devices 1.

Each of the one or more devices 1 is, for example, a small electronic device having an IC chip. Note that the small size is a size that can be attached to an article, and is usually smaller than the article, but may be the same or substantially the same size as the article, or may be larger than the article. The device 1 of this type is, for example, an IC tag, an IC card, or the like, but the type thereof does not matter. The device 1 is attached to an article and performs operations such as receiving emergency alert information or signals, and generating sound, light, or vibration in response to receipt of emergency alert information or the like. The articles, attachments, and generating operations will be described later.

The non-contact power feeder 2 performs non-contact power feeding to, for example, one or more devices 1. The non-contact power supply is a method of supplying electric power in a non-contact manner without using a metal contact or a connector. For the non-contact power feeding, for example, a radio wave transmission/reception type is suitable. The radio wave transmission/reception type is a method of converting electric power into radio waves and transmitting/receiving. The maximum distance at which wireless power transmission and reception can be performed in a non-contact manner is, for example, several meters to 10 meters, but may be more than 10 meters, and the numerical value is not limited. Note that radio wave transmission/reception type non-contact power supply is a known technique, and a detailed description thereof will be omitted.

However, the non-contact power feeding method may be a magnetic field resonance type or an electromagnetic induction type having a shorter power feeding possible distance, and its type is not limited. Note that the electromagnetic induction type power supply possible distance is, for example, about 10 mm, but may be more than 10 mm.

Therefore, for example, it is preferable that the radio wave transmission/reception-type non-contact power feeder 2 is provided in an area where radio waves for non-contact power feeding can reach, such as a home or an office building. Then, a device 1 of a radio wave transmission/reception type that receives electric power is attached to each of one or more articles placed at appropriate positions within the area, and operates by receiving electric power from the contactless power feeder 2.

Alternatively, a magnetic resonance type or electromagnetic induction type non-contact charger 2 is provided in a storage device such as a shelf, and one or more items are stored in the storage device, and one of the one or more items is stored. In addition, a device 1 of a type that receives power supply by a magnetic field resonance type or an electromagnetic induction type may be attached.

However, the contactless power feeder 2 is not essential. For example, the device 1 may include a battery and operate with the power from the battery. The battery may be, for example, a one-time-use primary battery or a secondary battery that can be charged and used repeatedly. The secondary battery may be charged with electric power from the contactless power feeder 2, for example.

The emergency alert information transmitter 3 transmits the emergency alert information to each of the one or more devices 1 and the emergency alert information receiver 4. The emergency alert information is information related to the emergency alert. The emergency alert is, for example, information that prompts immediate warning regarding a disaster that has occurred or is expected to occur. The disaster is, for example, a natural disaster such as an earthquake, a tsunami, or heavy rain, an emergency disaster such as a missile launch, and the type thereof is not limited.

The emergency alert information may be, for example, a signal indicating that an emergency alert has been issued, information for identifying the type of the issued emergency alert, or a voice signal of a predetermined alert sound. The audio signal is, for example, an electric signal corresponding to the waveform of the alarm sound, but may be considered as a sound wave of the alarm sound. In the latter case, the device 1 also has a microphone that converts sound waves into electrical signals. In addition, the emergency alert information may include detailed information about the details of the disaster that is the target of the emergency alert, and the content and the expression format are not limited. The detailed information is, for example, information on the scale, occurrence time, place, etc. of the disaster, but may be any information related to the details of the disaster.

The emergency alert information is, for example, J alert, L alert (registered trademark), emergency alert broadcast, or the like, but may be a fire alert signal, and its type is not limited.

The emergency alert information receiving device 4 receives the emergency alert information and transmits a signal to each of the one or more devices 1 in response to the receipt of the emergency alert information. The emergency alert information receiving device 4 may or may not output the received emergency alert information.

The signal is a signal that can be received by one or more of the devices 1 unless the power is off. The signal is, for example, a start signal. The activation signal is a signal for activating one or more devices 1. The activation means that the device 1 receives an emergency alert information from the emergency alert information transmitter 3 (hereinafter referred to as an emergency alert information receiving operation) and an operation that generates one or more of sound, light or vibration (hereinafter referred to as It can be said that it is a state in which such an operation can be performed from a state in which the generation operation) cannot be performed. However, the signal may be a signal that can be received by one or more devices 1, and that the device 1 that has received the signal is in a state in which the emergency alert information receiving operation and the generating operation can be performed as a result. So long as it doesn't matter. In the following, the signal will be described as an activation signal.

The state in which neither the emergency alert information receiving operation nor the generating operation can be performed is, for example, a shutdown state or a standby state (also referred to as a sleep state or a hibernation state). It can be said that the shutdown state is, for example, a state in which the power of the device 1 is off and only the operation of the power button can be accepted.

It can be said that the standby state is a state in which neither the emergency alert information receiving operation nor the generating operation can be performed, but the operation of receiving the activation signal (activation signal receiving operation) can be performed.

On the other hand, a state in which various operations including the emergency alert information receiving operation and the generating operation (hereinafter, normal operation) can be performed is called a normal state in the present embodiment.

The activation by the power button may be, for example, the activation from the shutdown state or the activation from the standby state, whereas the activation by the activation signal is usually the activation from the standby state.

Therefore, it can be said that the activation signal in the present embodiment is a signal for returning the IC chip 13 of the device 1 in the standby state to the normal state. The activation signal includes, for example, a device identifier and an activation command. The activation command is an instruction to instruct the device 1 to activate.

The device identifier is information that identifies the device 1. The device identifier is, for example, a MAC address or an IP address, but may be an ID, or any information that can identify the device 1. The device identifier included in the activation signal is a device identifier of the device 1 that should receive the activation signal, and may be, for example, a destination (that is, an address) of the activation signal.

However, the activation signal may not have the device identifier. That is, the activation signal may be broadcast to all the one or more devices 1.

The start signal to be broadcast may be, for example, a radio wave modulated with a predetermined waveform such as a PPM signal or a PWM signal, or infrared light that blinks in a predetermined pattern, regardless of its type or data structure. ..

However, the emergency alert information receiving device 4 is not essential. For example, each of the one or more devices 1 may have a function of receiving the emergency alert information, be in a normal state at all times, and be able to receive the emergency alert information from the emergency alert information transmitter 3.

Therefore, the minimum configuration of the disaster prevention system is one device 1 and the emergency alert information transmission device 3.

Alternatively, the emergency alert information transmitting device 3 may be a broadcasting device of a broadcasting station such as a television or a radio, and its type or location is not limited.

The emergency alert information receiving device 4 is realized using, for example, a mobile terminal, a wireless LAN access point, a television, a radio, or the like. The mobile terminal is, for example, a smartphone, a tablet terminal, a mobile phone, or the like, but the type thereof does not matter. Alternatively, the emergency alert information receiving device 4 may be implemented by a receiver dedicated to emergency alert information, or may be implemented by a server, a PC, or the like that is always connected to a network or the like.

It is preferable that the storage unit 130 stores, for example, two or more types of emergency alert identification information corresponding to two or more types of emergency alert information such as a J alert and a fire alarm signal.

The storage unit 130 also stores, for example, a flag indicating the state of the IC chip 13. The flag changes, for example, between "normal" indicating a normal state and "standby" indicating a standby state. The control of the flag is performed by the processing unit 132 described later, for example.

The receiving unit 131 receives one or more types of signals from the emergency alert information or the activation signal. For example, the receiving unit 131 receives the activation signal transmitted from the emergency alert information receiving device 4 that has received the emergency alert information in the standby state, and in the normal state, the emergency alert information transmitted from the emergency alert information transmitting device 3. To receive.

In the second modification lacking the emergency alert information receiving device 4, the receiving unit 131 receives the emergency alert information transmitted from the emergency alert information transmitting device 3. That is, for example, the IC chip 13 in Modification 2 does not transition to the standby state and always operates in the normal state even when no information is received for a predetermined time or longer, and the receiving unit 131 The emergency alert information transmitted from the emergency alert information transmitter 3 can be received.

The processing unit 132 performs various kinds of processing. The various types of processing are, for example, various types of determination described in the flowchart of FIG. 3 and control of the state of the IC chip 13 (for example, switching of the above-mentioned flags).

Further, the second storage unit 40 stores, for example, one or more device identifiers corresponding to one or more devices 1 configuring the disaster prevention system, and a start command. The second storage unit 40 also stores, for example, one or more emergency alert identification information. Further, the second storage unit 40 may store the above-mentioned signal identification information.

The emergency alert information receiver 41 receives the emergency alert information transmitted from the emergency alert information transmitter 3.

The second processing unit 42 performs various kinds of processing. The various processes include, for example, determining whether the emergency alert information receiving unit 41 has received the emergency alert information. The determination is made using, for example, one or more emergency alert identification information stored in the second storage unit 40.

The signal transmitter 43 transmits an activation signal to each of the one or more devices 1 in response to the emergency alert information receiver 41 receiving the emergency alert information. The signal transmission unit 43 may transmit the activation signal using the signal identification information stored in the second storage unit 40, for example.

The signal transmission unit 43 transmits an activation signal to each of the one or more devices 1 by using short-range wireless communication such as Bluetooth. Alternatively, the signal transmission unit 43 may transmit the activation signal to each of the one or more devices 1 via a network such as a wireless LAN.

Alternatively, the signal transmission unit 43 may broadcast the activation signal by radio waves to all the one or more devices 1. Alternatively, the signal transmission unit 43 may send an activation signal by infrared rays, which is used in a remote controller such as a television or an air conditioner, to one or more devices 1.

Alternatively, the signal transmitting unit 43 may transmit the activation signal to one or more devices 1 corresponding to the type of emergency alert information received by the emergency alert information receiving unit 41. Specifically, for example, the correspondence information is stored in the second storage unit 40. Correspondence information is a set of pairs of emergency alert identification information and device identifiers. The pair of the emergency alert identification information and the device identifier is, for example, the pair of the emergency alert identification information “J alert” and the device identifier “helmet”, the emergency alert identification information “fire notification signal” and the device identifier “fire extinguisher”. It may be a pair of.

The signal transmitting unit 43 identifies the type of emergency alert information received by the emergency alert information receiving unit 41 using the correspondence information stored in the second storage unit 40, and responds to the identified type of emergency alert information. A start signal is sent to one or more devices 1. For example, the signal transmission unit 43 transmits an activation signal to the device 1 attached to the helmet when a J alert is received, and is attached to a fire extinguisher when a fire notification signal is received. The activation signal may be transmitted to the existing device 1.

For the storage unit 130 and the second storage unit 40, for example, a nonvolatile recording medium such as a hard disk or a flash memory is suitable, but a volatile recording medium such as a RAM can also be realized.

The process of storing information in the storage unit 130 or the like does not matter. For example, the information may be stored in the storage unit 130 or the like via a recording medium, or the information transmitted via the network or the communication line may be stored in the storage unit 130 or the like. Alternatively, the information input via the input unit may be stored in the storage unit 130 or the like. The input means may be anything such as a keyboard, a mouse, a touch panel, etc.

The receiving unit 131 and the emergency alert information receiving unit 41 are normally realized by wired or wireless communication means (for example, a communication module such as NIC (Network interface controller) or modem), but a means for receiving broadcast (for example, , A broadcast receiving module).

The processing unit 132 and the second processing unit 42 can be usually realized by an MPU, a memory, or the like. The processing procedure of the processing unit 132 and the like is usually realized by software, and the software is recorded in a recording medium such as a ROM. However, the processing procedure may be realized by hardware (dedicated circuit).

The output unit 133 may or may not be considered to include an output unit such as a light emitting element or a speaker. The output unit 133 can be realized by the driver software of the output means or by the output means and the driver software thereof.

The signal transmission unit 43 is usually realized by a wired or wireless communication means, but may be realized by a broadcasting means (for example, a broadcasting module).

Next, the operation of the disaster prevention system will be described with reference to the flowchart of FIG. FIG. 3 is a flowchart illustrating an example of the operation of the device 1. In this flowchart, the device 1 has a function of receiving the emergency alert information from the emergency alert information transmitting device 3 and can receive the emergency alert information, and a signal from the emergency alert information receiving device 4. This is the operation when the state transitions to and from the standby state in which only reception is possible.

(Step S301) The processing unit 132 determines whether or not the state of the IC chip 13 is the standby state. If the state of the IC chip 13 is the standby state, the process proceeds to step S302, and if it is not the standby state, the process proceeds to step S305.

(Step S302) The processing unit 132 determines whether or not the receiving unit 131 has received the activation signal. When the receiving unit 131 receives the activation signal, the process proceeds to step S303, and when not received, the process returns to step S301.

(Step S303) The processing unit 132 returns the state of the IC chip 13 from the standby state to the normal state.

(Step S304) The output unit 133 generates one or more of sound, light, or vibration through one or more output means of the speaker, the light emitting element, or the vibrator. Then, it returns to step S301.

(Step S305) The processing unit 132 determines whether the state of the IC chip 13 is the normal state. If the state of the IC chip 13 is the normal state, the process proceeds to step S306, and if not, the process returns to step S301.

(Step S306) The processing unit 132 determines whether or not the receiving unit 131 has received the emergency alert information. When the receiving unit 131 receives the emergency alert information, the process proceeds to step S307, and when not received, the process proceeds to step S308.

(Step S307) The output unit 133 causes the speaker or the light emitting element to generate one or more of sound, light, or vibration through one or more output means of the vibrator. Then, it returns to step S301.

(Step S308) The processing unit 132 determines whether or not the state in which the receiving unit 131 does not receive any information (hereinafter, the non-receiving state) has continued for a predetermined time or more.

For example, the processing unit 132 performs the operation of resetting and starting the timer in response to the information received by the receiving unit 131. Along with this, the processing unit 132 also performs an operation of determining whether or not the value of the timer reaches or exceeds the threshold value, and when the value of the timer reaches or exceeds the threshold value, It is determined that the non-reception state has continued for a predetermined time or longer.

If the no-reception state continues for a predetermined time or more, the process proceeds to step S309, and if not, the process returns to step S301.

(Step S309) The processing unit 132 shifts the state of the IC chip 13 from the normal state to the standby state. Then, it returns to step S301.

In step S304 and step S307, the elapsed time from the start of the output of the sound or the like is measured, and the output of the sound or the like is stopped when the elapsed time reaches a predetermined time. You may return to S301.

Alternatively, for example, the device 1 may be provided with a reset button, the following step S304a may be added after step S304, and the following step S307a may be added after step S307.

(Step S304a) The processing unit 132 determines whether or not the reset button has been pressed. When the reset button is pressed, the process returns to step S301, and when not pressed, the process returns to step S304.

(Step S307a) The processing unit 132 determines whether or not the reset button has been pressed. If the reset button has been pressed, the process returns to step S301, and if it has not been pressed, the process returns to step S307.

Further, the device 1 has a function of receiving the emergency alert information from the emergency alert information transmitting device 3 and can always receive the emergency alert information (that is, between the normal state and the standby state). If there is no state transition), steps S301 to S305, S308 and S309 are omitted in the flowchart of FIG. This flowchart is composed of two steps S306 and S307. If NO in step S306, the process returns to step S306. After step S307, the process returns to step S306.

Although the device 1 does not have a function of receiving the emergency alert information from the emergency alert information transmitting device 3, it can always receive the signal from the emergency alert information receiving device 4 (that is, no state transition is made). In the case where a sound or the like is simply emitted in response to the reception of the signal), steps S301, S303, S305 to S309 are omitted in the flowchart of FIG. This flowchart is composed of two steps S302 and S304. If NO in step S302, the process returns to step S302, and if YES in step S302, the process proceeds to step S304. After step S304, the process returns to step S302.

Moreover, in the flowchart of FIG. 3, step S304 may be omitted. That is, the emergency alert information is transmitted twice or more, and at the time when the receiving unit 131 receives the signal transmitted from the emergency alert receiving device 4 according to the first emergency alert information, the IC chip 13 returns to the normal state. However, the output unit 133 may not output the sound or the like, and may output the sound or the like when the next emergency alert information is received.

Further, in the flowchart of FIG. 3, the process is started in response to the power-on of the device 1 or the activation of the program, and the process is ended by the power-off or the interrupt of the process end. However, the trigger for starting or ending the process does not matter.

One of the two or more devices 1 operates by using the electric power supplied from the contactless power feeder 2 and the electric power of the battery together. A secondary battery is suitable as the battery in this aspect. Electric power supplied from the contactless power supply 2 is stored in a battery that is a secondary battery, and the IC chip 13 operates with the electric power discharged from the battery. According to this aspect, even if the power supply from the contactless power feeder 2 is temporarily interrupted due to, for example, a power failure or an obstacle, the IC chip 13 operates using the power stored in the battery at that time. Therefore, the reliability of the device 1 is enhanced.

The other one of the two or more devices 1 normally operates with the electric power supplied from the contactless power supply 2, and when the power supply from the contactless power supply 2 is interrupted or insufficient, the battery is removed from the battery.
