Description

  The present invention relates to a sensor including a power-saving information transmission unit and a disaster prevention support system that allows a mobile terminal carried by a fire brigade to acquire position information.

  It is desired to perform various wireless communications using fire detectors installed at various locations in a building of an automatic fire alarm system that can operate for a predetermined period even during a power failure. For example, if a fire detector set to a unique address can send the address and be received by the mobile terminal, it can remotely identify the fire detector set incorrectly. .

  Alternatively, if a history such as fire detector reporting or self-diagnosis is transmitted and received by the mobile terminal, the history information of the sensor can be acquired remotely.

  A mobile terminal carried by a member of a self-defense fire brigade organized by a building subject to fire prevention or a public fire brigade member who arrived at a building where a fire has occurred due to a call is reported from such a fire detector. By making it possible to acquire location information that indicates your location based on the information that is transmitted, even if you cannot obtain a good view in the smoke, you can inform each member of their location Become.

  However, even with the use of the low-power wireless communication technology called Bluetooth Low Energy (hereinafter referred to as BLE), which is the Bluetooth4 extension specification of the short-range wireless communication standard Bluetooth (registered trademark), it consumes several tens of mW of power, especially power saving. Even if it is designed in this way, at least several mW is consumed (Non-patent Document 1). However, the power consumption of the fire detector in the monitored state is extremely small, for example, the current consumption when DC 24 V is applied is 15 to 60 μA (Non-patent Document 2). In other words, the power consumption of the fire detector in the monitoring state is as small as several hundred μW, which is orders of magnitude smaller than BLE. Therefore, the BLE technology, which requires an order of magnitude higher power than the fire detector, is not used as a wireless communication means driven by a common power source with the fire detector. In the first place, automatic fire alarm equipment is not allowed to stop functioning even during a power failure, and must continue to operate. For this purpose, a battery as a standby power source is provided. For example, in Japan, a fire receiver of an automatic fire alarm system connected to a fire detector can maintain a fire alarm state for a predetermined number of lines for 10 minutes after maintaining the monitoring state for one hour even during a power failure. It is stipulated in the “Ministry of Internal Affairs and Communications that establishes technical standards” that a standby power supply (battery) must be provided. For this reason, if the power consumption of the fire detector is greatly increased, the operation at the time of a power failure cannot be guaranteed if the standby power capacity of the fire receiver remains unchanged. In addition, today's fire detectors are generally two-wire systems, and power is supplied from a fire receiver to multiple fire detectors via two signal lines, and the fire receiver and multiple fire detectors are connected. Communication between. If the power consumption of the fire detector is greatly increased, a large voltage drop is caused by the impedance of the signal line, which hinders communication between the fire receiver and the fire detector. For this reason, even if it was going to use BLE technology, the wireless communication means which shares a power supply part with a fire detector could not be provided in a fire detector.

  As a wireless communication technology that saves even more power than BLE technology, RFID tags do not transmit radio waves themselves, but modulate and reflect radio waves from the readout device according to impedance changes, and the readout device that receives this acquires information A backscatter modulation technique is used. However, the communication is generally limited to binary modulation of 1 or 0. In this backscatter modulation, there is a technique that enables multi-level modulation by performing PSK modulation (Phase Shift Keying) on the radio wave reflected toward the reading device. However, it does not attempt to send information to surroundings and let unspecified receiving means acquire information. Bluetooth (registered trademark) and Wi-Fi (registered) that mobile devices such as smartphones and tablet devices generally have Information is not acquired by a communication means based on a communication standard such as a trademark. For example, DQPSK modulation (Differential Quadrature Phase Shift Keying) used in the wireless LAN standard IEEE802.11b is not performed (Patent Document 1).

  On the other hand, some residential fire alarms that can continue to operate for about 10 years with battery power supply have multiple alarms linked by wireless communication. However, wireless communication in this case is performed intermittently, and the amount of information is extremely limited. For example, in Japan, it is based on “Radio Equipment Standards for Radio Stations of Low Power Security Systems” (Radio Industry Association Standard RCR STD-30) defined for radio equipment of low power security systems. Therefore, the amount of information that can be communicated wirelessly with residential fire alarms is extremely limited, and in addition, there are many such as Bluetooth (registered trademark) and Wi-Fi (registered trademark) that mobile terminals such as smartphones and tablet terminals generally have. Information communication was not possible using value modulation.

According to the configuration of (1), the radio wave from the outside is modulated and reflected by a small power consumption only for changing the impedance of the transmitter without itself radiating an electromagnetic wave with a large power consumption.

  An embodiment of the present invention will be described with reference to FIGS.

<Overall configuration>
FIG. 1 is a diagram illustrating an example of a configuration of an automatic fire alarm facility and a communication system according to an embodiment of the present invention. The receiver 1 issues an alarm based on an abnormal signal from the sensor 10, and the fire receiver constituting the automatic fire alarm facility is an example of the receiver 1. To the pair of signal lines 2 drawn out from the receiver 1, a plurality of sensors 10 disposed in the building to be fire-protected are connected. The sensor 10 sends an abnormal signal to the receiver 1 via the signal line 2 when detecting an abnormality in the monitoring area, and constitutes an automatic fire alarm facility. A fire detector that sends a fire signal when a fire is detected, and a gas leak detector that sends a gas leak signal when a gas leak is detected are examples of the sensor 10. Here, when the detected physical quantity satisfies a predetermined condition (for example, when the detected temperature exceeds a predetermined temperature), the sensor 10 outputs a predetermined signal indicating the occurrence of an abnormality as an abnormal signal (“alert” ”) Type (referred to as on-off type), or a type that outputs a signal indicating a detected physical quantity (eg, temperature) (referred to as analog type or variable output type). Good. When the sensor 10 is an analog type sensor, the receiver 1 that has received a signal from the sensor 10 receives a signal that satisfies a predetermined condition (for example, exceeds a predetermined reference value). ), It is determined that an abnormality has been detected. Therefore, when the sensor 10 is an analog type sensor, when the sensor 10 outputs a signal satisfying a predetermined condition indicating abnormality detection (for example, a signal exceeding a reference value), the abnormality signal is output. . The receiver 1 supplies power to each sensor 10 via the signal line 2.

  The radio wave transmission device 30 is provided at a position where the radio wave reaches the sensor 10. A plurality of radio wave transmission devices 30 may be installed so that radio waves reach the plurality of sensors 10. That is, the sensor 10 is provided at a position where radio waves from the radio wave transmission device 30 provided outside reach. The radio wave transmission device 30 is an example of an electromagnetic wave radiation unit that radiates an electromagnetic wave. For example, the radio wave transmission device 30 is provided in a monitoring area of the sensor 10 and transmits a carrier wave as a predetermined electromagnetic wave. A carrier wave, that is, a radio wave is indicated by an arrow 31 in FIG. The sensor 10 includes information transmitting means for modulating and reflecting the carrier wave based on stored transmission information and transmitting the modulated carrier wave toward the surroundings. The modulated wave reflected by the sensor 10 is indicated by the arrow 32 in FIG.

  The mobile terminal 20 is a portable terminal that includes a communication unit that receives radio waves modulated by the sensor 10 and obtains transmission information transmitted from the sensor 10. For example, the mobile terminal 20 is a smartphone, a tablet terminal, or a PDA (mobile phone). Information terminal).

<Configuration of sensor 10>
FIG. 2 is a block diagram illustrating an example of the configuration of the sensor 10. The sensor 10 includes a power supply unit 11, an abnormality detection unit 12, a notification unit 13, a storage unit 14, a control unit 15, a modulation unit 16, a transmitter 17, and a communication unit 18.

  The communication unit 18 is a communication unit for the sensor 10 to communicate with the receiver 1. In the present embodiment, description will be made assuming that wired communication with the receiver 1 is performed via the signal line 2. When the sensor 10 is a wireless fire sensor, the communication unit 18 is replaced with wireless communication means.

  The power supply unit 11 is a power supply unit that receives power via the signal line 2 and supplies power for driving itself. The power supply unit 11 can receive power supply from the signal line 2 for a predetermined time even during a power failure. For example, in an automatic fire alarm system, the receiver 1 is equipped with a storage battery that can maintain an alarm operation for a predetermined number of lines for 10 minutes after being monitored for 1 hour as a standby power supply. By receiving, the power supply unit 11 can supply power to each unit of the sensor 10 during the power outage. When the sensor 10 is a wireless fire sensor, for example, the power supply unit 11 can be a battery power source. In this case, the wireless fire detector can be driven without replacing the battery power source for 10 years, for example.

  The abnormality sensing unit 12 is sensing means for sensing an abnormality in the monitoring area. The fire detector of the fire detector and the gas leak detector of the gas leak detector are examples of the abnormality detector 12.

  The reporting unit 13 is a control unit for transmitting an abnormal signal that transmits an abnormal signal from the communication unit 18 to the receiver 1 when the abnormality detecting unit 12 detects an abnormality. A functional configuration that shares a control unit such as a CPU with the control unit 15 described later may be used, or a control unit different from the control unit 15 may be used.

  The memory | storage part 14 is a memory | storage means to memorize | store the information transmitted toward the circumference | surroundings from the transmitter 17 mentioned later as transmission information. The transmission information can be arbitrarily set. For example, the transmission information is a unique identifier for each sensor 10, and is an address or a serial number for transmission in the automatic fire alarm facility. The storage unit 14 is appropriately configured by a storage unit such as a RAM, a ROM, a flash memory, or the like according to stored transmission information.

  The control unit 15 is control means for sending a control signal for transmitting the transmission information read from the storage unit 14 to the modulation unit 16 described later. For example, when the alarm unit 13 transmits an abnormal signal, or at a predetermined timing such as a predetermined cycle, control is performed so that transmission information is transmitted from the transmitter 17. The control unit 15 may have a functional configuration sharing a control unit such as a CPU together with the reporting unit 13, or may be a control unit different from the reporting unit 13.

  The modulation unit 16 is a modulation unit that changes impedance based on a control signal from the control unit 15, and gives impedance change to the transmitter 17 described later. For example, an impedance change is given to the transmitter 17 by switching the impedance element connected to the transmitter 17 with a switching element. If an electric field control type semiconductor element such as a MOS-FET is used as the switching element, it is possible to modulate radio waves that have arrived from the outside without consuming electric power. In reality, there is a small amount of power consumption due to the charge consumption associated with switching, but much less power is required than the power for transmitting radio waves.

  The transmitter 17 is a transmitter that is connected to the modulator 16 and modulates and reflects an external electromagnetic wave based on a change in impedance. For example, an antenna that modulates and reflects an external carrier wave, that is, a radio wave based on the change in impedance is an example. The transmitter 17 reflects the radio wave from the radio wave transmitter 30 so as to be modulated based on a change in impedance, transmits the modulated radio wave to the surroundings, and receives it to acquire transmission information.

<Operation>
The control unit 15 of the sensor 10 reads the transmission information from the storage unit 14 and sends a control signal to the modulation unit 16 so as to modulate the radio wave received from the radio wave transmission device 30 with the transmission information. Based on the control signal, the modulation unit 16 to which the transmitter 17 is connected modulates the transmission information to be placed on the radio wave reflected by the transmitter 17 by changing the impedance. That is, the control unit 15, the modulation unit 16, and the transmitter 17 constitute an information transmission unit. Then, the mobile terminal 20 in the vicinity of the sensor 10 receives the modulated radio wave from the information transmission means and acquires the transmission information. For example, when the transmission information is the address of the sensor 10, the transmission information acquired by the mobile terminal 20 is displayed on the display unit, whereby the sensor 10 with an erroneous address set can be found. . Further, for example, when the transmission information is the manufacturing number of the sensor 10, by displaying the transmission information acquired by the mobile terminal 20 on the display unit, the manufacturing number of the sensor 10 can be known. The history can be checked.

  Thus, the information transmitting means of the sensor 10 modulates and reflects the radio wave from the radio wave transmitting device 30, and the sensor 10 itself does not transmit the radio wave. As described above, by giving an impedance change to the transmitter 17 by the switching operation of the electric field control type switching element, it is possible to modulate an external radio wave with a slight power consumption of about several tens of μW. Therefore, transmission information can be transmitted with extremely small power of about several tens of μW, and the above-mentioned information transmitting means can be transmitted with a slight increase in power consumption even with a sensor having a very small power consumption of several hundred μW in a monitoring state. Can be provided. And since the information transmission means can be driven using the power supply unit 11 that supplies all the power that drives itself from the power supplied via the signal line 2, the above information transmission means is connected to the sensor 10. Can be built in. As a result, information can be transmitted even during a power failure.

<Modification>
The embodiment described above can be modified as follows. Moreover, you may combine these modifications.

[Modification 1]
In the embodiment described above, the transmission information may always be transmitted from the sensor 10 or may be transmitted from the sensor 10 at a predetermined period. Moreover, you may make it transmit based on the instruction | command from the receiver 1. FIG. For example, the sensor 10 receives a command from the receiver 1 via the signal line 2. At this time, the sensor 10 receives a command from the receiver 1 via the communication unit 18. For example, at the time of inspection, it is instructed to transmit self-diagnosis information or setting information from the fire receiver 1 to the detector 10 based on the operation of the operator, and this information is acquired by the mobile terminal 20 carried by the inspector. May be. Also, for example, in the event of a fire, the receiver 1 is instructed to send fire information and a beacon to the sensor 10, and the fire information and beacons are acquired by the mobile terminal 20 carried by the fire brigade, and the acquired fire information is The fire information is displayed on the display unit of the acquired mobile terminal 20 or the mobile terminal 20 that has acquired the beacon acquires the position information from the support server 40 based on the identifier included in the beacon, and the acquired position information is You may make it display on the display part of the mobile terminal 20. FIG. Further, the radio wave transmission device 30 includes a communication unit that communicates with the outside via the communication line 60, and is operated so as to operate only when sending information is transmitted from the sensor 10 based on a command from the outside, for example, reception You may control to operate | move based on the instruction | command from the machine 1. FIG. In this case, the receiver 1 and the center terminal 50 to be described later may be provided with communication means for issuing a command to the radio wave transmission device 30 via the communication line 60, or the command to the support server 40. The support server 40 that includes a communication unit for emitting the command and that receives the command may issue the command to the radio wave transmission device 30. By comprising in this way, the useless power consumption in the said building can be suppressed by stopping the radio wave transmitter 30 when it is unnecessary.

[Modification 2]
In the above-described embodiment, the radio wave reflected by the transmitter 17 has a plurality of data values (for example, 4 values = 2 bits) by a plurality of (for example, 4) patterns shifted by a predetermined phase difference (for example, 90 °). ), Phase shift keying may be performed. For example, the modulation unit 16 performs phase shift keying (for example, DQPSK modulation) by changing the impedance based on the control signal transmitted from the control unit 15. At this time, the control unit 15 sends a plurality of (for example, four) rectangular waves giving a plurality of data values based on the transmission information read from the storage unit 14 to the modulation unit 16 as control signals. This is demodulated by the mobile terminal 20 in the vicinity of the sensor 10 (specifically, the wireless LAN communication unit of the mobile terminal 20) to acquire the transmission information (for example, conforming to IEEE802.11b).

  With this configuration, it is possible to multi-value modulate the information transmission from the sensor 10. For example, DQPSK modulation used in the wireless LAN standard IEEE802.11b can be supported by performing QPSK modulation with four rectangular waves whose phases are shifted by π / 2. Therefore, information can be acquired by wireless transmission to a communication means that is typically provided in a smartphone or tablet terminal as the mobile terminal 20.

  Note that multi-level modulation is not limited to the above, and may be adapted to, for example, Bluetooth (registered trademark), and similarly, wireless transmission is performed to a communication means that is normally provided in a smartphone or tablet terminal as the mobile terminal 20. Information can be acquired.

[Modification 3]
In the embodiment described above, the sensor 10 transmits the transmission information at a timing different from that of the other sensors 10 based on its own unique value (address, identifier, serial number, etc.). Means may be provided. With this configuration, the sensors 10 transmit information at different timings, so that the mobile terminal 20 does not receive information from the plurality of sensors 10 at the same time, and interference can be prevented.

[Modification 4]
