Description

  The present invention relates to an alarm device that issues an alarm when an environmental value indicating an environmental change exceeds an allowable range.

  2. Description of the Related Art Conventionally, an alarm device that issues an alarm when an abnormality in an indoor environment is detected has been widely used in buildings, underground malls, ordinary houses, and the like. As such an alarm device, an alarm device that performs fire detection or gas detection by detecting smoke, heat, gas, or the like, which is an environmental value representing an environmental change, is generally popular. Also, an alarm device for detecting a human body that detects a suspicious person by providing a human sensor such as an infrared sensor that detects far infrared rays emitted by a human body is also provided.

Such various alarm devices include various detectors for detecting an environmental value, and a sound generator such as a piezoelectric buzzer or a speaker that issues an alarm when the environmental value from the detector exceeds a predetermined value. Prepare. And the alarm device provided with such a detector and a sounding body is housed in a single casing and integrated with the detector and the sounding body. As the alarm device in which the sounding body and the detector are integrally configured as described above, for example, a heat-sensitive fire alarm device (see Patent Document 1) including a heat-sensitive element such as a thermistor as a detector, or a light-emitting element. In addition, a smoke detection type fire alarm (see Patent Document 2) including a smoke detector having a light receiving element as a detector is provided.
JP 09-044769 A JP 2005-352932 A

  However, in the case of an alarm device in which the sounding body and the detection unit are configured integrally, not only a space is required for sufficient sound volume from the sounding body at the time of reporting, but also the environmental value is detected by the detection unit. As possible, the installation position of the sounding body and the detection unit is preferably a position that does not affect each other. Therefore, not only the downsizing of the alarm device is limited, but the fire alarm device and the like in Patent Document 1 and Patent Document 2 have to have a shape in which the sensing portion protrudes.

  In the case of an alarm device in which the sounding body and the detection unit are integrally formed, the alarm device is often installed so that the detection unit is installed at a position where the environmental value can be easily detected. For this reason, depending on the location where the alarm device is installed, there may be a shield or the like, so that the volume of the alarm issued from the sounding body may be reduced, and the effect of alerting the person may be reduced. On the other hand, when an alarm device is constructed with an emphasis on alerting people, the detection efficiency of the environmental value by the detector may decrease.

  In view of such a problem, an object of the present invention is to propose an alarm device excellent in workability and designability by separating the detection unit and the alarm unit and making them separate.

  In order to achieve the above object, the alarm device of the present invention includes a detection unit that measures an environmental value indicating a change in the environment, and an alarm unit that notifies an external alarm, and the environmental value measured by the detection unit. In the alarm device that determines alarm notification by the alarm unit based on the sensor unit, the detection unit controls the environmental value, and the environmental value measured by the sensor unit while controlling the operation of the sensor unit And a first communication unit connected to the first control unit, and the alarm unit is communicatively connected to the notification unit for notifying the alarm and the first communication unit. A second control unit that is connected to the second communication unit and that controls the operation of the notification unit, and that the detection unit and the alarm unit can be installed separately. Features.

  In such an alarm device, a plurality of detection units may communicate with one alarm unit, or a plurality of alarm units may communicate with one detection unit.

  And in the said detection part, the said 1st control part determines the necessity of alerting | reporting of an alarm based on the said environmental value which the said sensor part measured, and the said 1st communication part is the determination by the said 1st control part The result may be transmitted to the alarm unit. That is, since it is possible to determine whether or not alarm notification is required in the detection unit, communication can be performed between the detection unit and the alarm unit only when an alarm is notified.

  In the alarm unit, the second communication unit receives the environmental value measured by the sensor unit transmitted from the detection unit, and the second control unit receives the environmental value received by the second communication unit. The necessity of alarm notification may be determined based on the environmental value.

  The alarm device of the present invention includes a detection unit that measures an environmental value indicating an environmental change, and an alarm unit that notifies an alarm to the outside, and the alarm by the alarm unit based on the environmental value measured by the detection unit In the alarm device that determines the notification, the detection unit and the alarm unit are configured separately and are connected to each other for communication, and the detection unit and the alarm unit communicate with each other to detect the detection. When the environmental value measured by the unit becomes a value that requires alarm notification, the alarm unit notifies the alarm.

  According to the present invention, the detection unit and the alarm unit which are connected to each other by communication are separated from each other, so that each of the detection unit and the alarm unit can be installed at an optimal position. Therefore, when the optimal position for measuring the environmental value to be measured is different from the position where the alarm is easily notified to the householder, the detection unit and the alarm unit can be arranged at each position. Effective measurement and alarm notification. In addition, since each of the detection unit and the alarm unit can be configured with only necessary components, each can be reduced in size, and there is no restriction on the installation location.

A basic configuration of the alarm device of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a schematic diagram showing the configuration of the alarm device of the present invention. FIG. 2 is a block diagram showing an internal configuration of the alarm device shown in FIG.

The alarm device 1 shown in FIG. 1 includes a detection unit 10 that detects smoke, gas, or a human body, and an alarm unit 11 that communicates with the detection unit 10 and performs an alarm notification operation to the outside. The detection unit 10 and the alarm unit 11 include a LAN (Local Area Network) line, a DSL (Digital Subscriber).
Line (Line) line, PLC (Power Line Communications) line or wired line such as optical fiber line may be used for communication, or wireless LAN, Bluetooth, or wireless line such as infrared ray. It is good also as what communicates by.

  And when communication by a wired line is performed between the detection part 10 and the warning part 11, the power supply line for electric power supply is connected between the detection part 10 and the warning part 11, and the detection part 10 And the alarm unit 11 may be mounted with a power supply unit. Further, when communication is performed between the detection unit 10 and the alarm unit 11 via a wireless line, a power supply unit is mounted on each of the detection unit 10 and the alarm unit 11. In addition, in FIG. 1, the alarm device 1 in which the detection unit 10 and the alarm unit 11 perform wireless communication is illustrated.

  In the alarm device 1 configured by separating the detection unit 10 and the alarm unit 11 as described above, each of the detection unit 10 and the alarm unit 11 includes an internal configuration as illustrated in FIG. 2. That is, the detection unit 10 transmits and receives signals to communicate with the alarm unit 11 and the sensor unit 100 that measures the environmental value, the first control unit 101 to which the environmental value measured by the sensor unit 100 is given, and the alarm unit 11. And a first communication unit 102 configured by a communication interface.

  When the detection unit 10 detects a fire, the sensor unit 100 is an optical smoke sensing sensor constituted by a light emitting element, a light receiving element and an optical component, or a heat sensing sensor such as a thermistor. The When the detection unit 10 detects the gas amount, the sensor unit 100 measures the gas amount. Further, when the detection unit 10 detects a human body, the sensor unit 100 is configured by an infrared sensor that receives infrared rays emitted from the human body.

  In addition, the alarm unit 11 receives the signal from the detection unit 10 received by the second communication unit 110 and the second communication unit 110 configured by a communication interface for communication connection with the first communication unit 102 of the detection unit 10. A second control unit 111 that determines whether or not an alarm notification operation is necessary, a sound generator 112 that is controlled by the second control unit 111, and a display whose display operation is controlled by the second control unit 111. Unit 113. In the alarm unit 11, the sounding body 112 and the display unit 113 operate as an informing unit for informing the outside of the alarm.

  Note that the sounding body 112 may be constituted by a piezoelectric buzzer that issues a sound by a buzzer sound, or may be constituted by a speaker that reproduces and outputs alarm contents as sound. Further, the display unit 113 may be configured by an LED (Light Emitted Diode) that blinks or lights up, or may be configured by a liquid crystal display that can display alarm contents. Furthermore, not only the sounding body 112 and the display unit 113 but also a vibration motor that vibrates the alarm unit 11 main body may be provided as a part of the notification unit, and the notification operation may be performed by vibration of the alarm unit 11 main body.

  The alarm device 1 provided with the detection unit 10 and the alarm unit 11 separately configured as described above is configured so that when the power is turned on after the detection unit 10 and the alarm unit 11 are installed, the first communication unit 102 and the alarm of the detection unit 10 are alarmed. Communication is performed with the second communication unit 110 of the unit 11 to confirm whether communication is possible with each other. The communication for confirming whether or not communication with each other is possible is performed by the detection unit 10 in each of the following embodiments, but may be performed by the alarm unit 11 as a matter of course. When the detection unit 10 and the alarm unit 11 confirm that they can communicate with each other, the sensor unit 100 measures the environmental value in the detection unit 10. At this time, the sensor unit 100 is controlled by the first control unit 101 to measure the environmental value at every predetermined timing, and an electrical signal based on the environmental value as a measurement result is given to the first control unit 101.

  The necessity of alarm notification is determined based on the measurement result by the sensor unit 100. As described later, the necessity of alarm notification depends on the first control unit 101 of the detection unit 10 or the alarm unit 11 of the alarm unit 11. 2 is determined by one of the control units 111. When the first control unit 101 of the detection unit 10 determines whether the alarm notification is necessary, the determination result by the first control unit 110 is the first determination result of the detection unit 10 when the alarm notification is necessary. It is transmitted from the communication unit 102 to the second communication unit 110 of the alarm unit 11. In addition, when the second control unit 111 of the alarm unit 11 determines whether or not the alarm notification is necessary, every time the sensor unit 100 measures the environmental value, the measurement result by the sensor unit 100 is obtained from the detection unit 10. It is transmitted from the first communication unit 102 to the second communication unit 110 of the alarm unit 11.

  When it is determined that alarm notification is necessary, in the alarm unit 11, the second control unit 111 controls the operation of the notification unit including the sound generator 112 or the display unit 113. As a result, an alarm is issued by the sounding body 112 or an alarm is displayed by the display unit 113, so that the alarm unit 11 notifies the outside of the alarm. Therefore, the alarm unit 11 separated from the detection unit 10 is installed near the householder, so that the alarm can be reliably notified.

  As described above, an embodiment of the alarm device 1 configured by the detection unit 10 and the alarm unit 11 that can be installed separately and communicate with each other will be described with the configuration of FIGS. 1 and 2 as a common configuration. In each of the following embodiments, an alarm device having a one-to-one relationship between the detection unit 10 and the alarm unit 11 will be described as an example, as in the configuration of FIGS. 1 and 2. As shown in FIG. 4, the present invention can be applied even if there are a plurality of detection units 10 and alarm units 11.

<First Embodiment>
The alarm device of 1st Embodiment in this invention is demonstrated with reference to drawings. FIG. 3 is a flowchart showing the operation of the detection unit of the alarm device in the present embodiment, and FIG. 4 is a flowchart showing the operation of the alarm unit of the alarm device in the present embodiment. Note that, as described above, in each of the following embodiments including this embodiment, the alarm device 1 includes the detection unit 10 and the alarm unit 11 as illustrated in FIGS. 1 and 2. That is, in each of the following embodiments including this embodiment, the operation of each of the detection unit 10 and the alarm unit 11 that are characteristic in each embodiment is assumed with reference to the basic configuration described above for the configuration of the alarm device 1. explain.

  In order for each of the detection unit 10 and the alarm unit 11 constituting the alarm device 1 of the present embodiment to be operated as the alarm device 1 after being installed separately as shown in FIG. 1, the detection unit 10 and the alarm unit 11 Each power supply is turned on. The operation of the detection unit 10 and the alarm unit 11 after the power is turned on will be described below with reference to the flowcharts of FIGS.

  When the power is turned on after installation (S1), the detection unit 10 confirms that the alarm unit 11 is in a standby state in order to establish communication with the alarm unit 11 connected by a wired line or a wireless line. A signal is generated by the first control unit 101 and transmitted from the first communication unit 102 (S2). Then, the first control unit 101 confirms whether or not there is a response from the alarm unit 11 in the first communication unit 102 (S3), and repeats transmission of a confirmation signal until there is a response from the alarm unit 11. At this time, the communication between the detection unit 10 and the alarm unit 11 is not established until the response from the alarm unit 11 is confirmed, and thus the alarm cannot be notified. Therefore, the power supply to the sensor unit 100 may be stopped, and the environmental value measurement operation by the sensor unit 100 may not be started.

  On the other hand, when the alarm unit 11 is turned on after installation (S11), the alarm unit 11 enters a standby state for receiving a transmission signal from the detection unit 10 (S12), and the second control unit 111 includes the second communication unit 110. The presence / absence of the receiving operation is confirmed (S13). The operation of the second control unit 111 in S12 and S13 is repeated until the second communication unit 110 receives a signal from the detection unit 10. And in the 2nd communication part 110, if the signal transmitted from the 1st communication part 102 of the detection part 10 is received (it is Yes at S13), the 2nd control part 111 will alert | report operation | movement by the transmission signal from the detection part 10. It is determined whether or not the notification request signal is for requesting (S14). At this time, when the second control unit 111 recognizes that the signal received by the second communication unit 110 is a confirmation signal from the alarm unit 10 (No in S14), a response signal to the confirmation signal is transmitted to the second control unit 111. Is generated and transmitted from the second communication unit 110 (S15).

  In this way, the detection unit 10 repeats the operations of S2 and S3 after the power is turned on by S1, thereby transmitting a confirmation signal at every predetermined timing, and the alarm unit 11 performs the operations of S12 to S14 after the power is turned on by S11. By repeating the above, reception of the confirmation signal from the detection unit 10 can be confirmed. Then, the alarm unit 11 returns a response signal to the detection unit 10 in response to the confirmation signal from the detection unit 10 by the operation of S15, so that the detection unit 10 and the alarm unit 11 can communicate with each other. Recognize that. Thereby, communication between the detection part 10 and the warning part 11 is established, and the operation | movement as the alarm device 1 by the detection part 10 and the warning part 11 starts.

  When the communication between the detection unit 10 and the alarm unit 11 is established, the detection unit 10 starts measurement of the environmental value by the sensor unit 100, and the alarm notification based on the measurement value of the sensor unit 100 is started. A determination regarding necessity is made. That is, when the first control unit 101 confirms reception of the response signal from the alarm unit 11 in the first communication unit 102 (Yes in S3), the sensor unit 100 is driven and the environmental value measured by the sensor unit 100 is measured. Is acquired (S4). And if the sensor part 100 gives the measured environmental value to the 1st control part 101 as an electrical signal, power supply will be stopped and the measurement operation | movement will be stopped. In addition, the first control unit 101 to which an electrical signal serving as an environmental value is given from the sensor unit 100 starts time measurement by a timer (not shown) (S5).

  The first control unit 101 that has received the electrical signal that is the environmental value measured by the sensor unit 100 determines whether or not the environmental value has exceeded a threshold value that is an alarm range, and the alarm unit 11 needs to notify the alarm. It is determined whether or not (S6). When the measured environmental value is not in the alarm range and alarm notification is not required (No in S6), the first control unit 101 performs the measurement operation of the sensor unit 100 in S4 according to the time measured by a timer (not shown). It is confirmed whether or not a predetermined time has passed (S7). At this time, when the predetermined time has not elapsed since the measurement operation of the sensor unit 100 (No in S7), the standby state in the detection unit 10 is maintained (S8).

  That is, until the predetermined time elapses, the operations of S7 and S8 are repeated, and in the detection unit 10, only the time confirmation by the first control unit 101 operates (S7). When a predetermined time has elapsed from the measurement operation of the sensor unit 100 by S4 (Yes in S7), the process proceeds to S4, and the environmental value measurement operation by the sensor unit 100 is performed again. Therefore, after the measurement operation by the sensor unit 100 is performed, the operations of the sensor unit 100 and the first communication unit 102 can be stopped until it is confirmed that the measured value reaches the alarm range or elapse of a predetermined time. Therefore, the power supply to the sensor unit 100 and the first communication unit 102 can be stopped until the first control unit 101 confirms that the measured value reaches the alarm range or a predetermined time has elapsed. Further, by repeating the operations of S4 to S8, until the first control unit 101 confirms that the environmental value to be measured is in the alarm range (Yes in S6), the sensor unit 100 is in the environment at every predetermined timing. Performs a value measurement operation.

  As described above, the detection unit 10 performs the environmental value measurement operation and the determination operation regarding the necessity of alarm notification at predetermined timings by the operations of S4 to S8. When the first control unit 101 confirms that the environmental value measured by the sensor unit 100 has reached the alarm range while repeating these operations (Yes in S6), the first control unit 101 detects the alarm. A notification request signal for requesting notification is generated and transmitted from the first communication unit 102 (S9).

  Although not shown in the flowchart of FIG. 3, the detection unit 10 that has transmitted the notification request signal in this way is operated directly on the detection unit 10 or communicates with the alarm unit 11. When the restoration is requested based on the above, the operation is restored, and the operations after S4 are repeated again. Further, when the detection unit 10 is recovered by direct operation, the first communication unit 102 generates an alarm after the first control unit 101 generates a signal for instructing the alarm unit 11 to restore the operation. To the unit 11.

  On the other hand, the alarm unit 11 transmits a response signal from the second communication unit 110 (S15), and even after communication with the detection unit 10 is established, the alarm unit 11 enters a standby state (S12), and transmits a transmission signal from the detection unit 10. The presence or absence of reception is confirmed (S13). In the standby state for confirming whether or not the transmission signal is received, the alarm unit 11 is configured to supply power to the circuit part for performing the signal reception operation by the second communication unit 110, thereby reducing power consumption. Electricity can be achieved. At this time, in the detection unit 10 that operates according to the flowchart of FIG. 3, when the measurement value by the sensor unit 100 is confirmed to be in the alarm range and the notification request signal is transmitted from the first communication unit 102, the alarm unit 11. Receives the notification request signal from the detection unit 10 by the second communication unit 110.

  Therefore, after the second control unit 111 confirms that the transmission signal from the detection unit 10 is received by the second communication unit 110 (Yes in S13), the received transmission signal from the detection unit 10 is a notification request signal. Recognize that it exists (Yes in S14). Accordingly, the second control unit 111 recognizes that the alarm notification operation is requested by the detection unit 10, so that the alarm unit 112 and the display unit 113 perform the alarm notification operation. Power supply is started (S16). And this alerting | reporting part is controlled by the 2nd control part 111, and alerting | reporting operation | movement of an alarm starts (S17). That is, an alarm is issued from the sounding body 112 and a display indicating the alarm is made by the display unit 113. In S16, simultaneously with the start of power supply to the notification unit, power supply may be started for the control circuit portion of the notification unit by the second control unit 111.

  Although not shown in the flowchart of FIG. 4, after the alarm unit 11 starts the notification operation by the notification unit in S <b> 17, the alarm unit 11 is directly operated, or the detection unit 10. When the recovery is requested based on the communication with, the operation is recovered, and the operations after S12 are repeated again. When the alarm unit 11 is restored by direct operation, the second control unit 111 generates a signal for instructing the detection unit 10 to restore the operation, and then the second communication unit 110 detects the signal. It may be transmitted to the unit 10.

  Thus, after the communication with the detection unit 10 is established after the power is turned on, the alarm unit 11 is in a standby state until the notification request signal from the detection unit 10 is received, and the power to the circuit portion that performs the alarm notification operation Since the supply can be stopped, the power consumption of the alarm device 1 can be reduced. In addition, after communication is established, not only the signal from the detection unit 10 is not transmitted until the measured value reaches the alarm range, but the alarm unit 11 only needs to confirm reception of the signal from the detection unit 10. In addition, the amount of communication on the communication line between the detection unit 10 and the alarm unit 11 can be reduced.

<Second Embodiment>
An alarm device according to a second embodiment of the present invention will be described with reference to the drawings. FIG. 5 is a flowchart showing the operation of the detection unit of the alarm device in the present embodiment, and FIG. 6 is a flowchart showing the operation of the alarm unit of the alarm device in the present embodiment. In the operation steps shown in FIGS. 5 and 6, the same steps as those shown in the flowcharts of FIGS. 3 and 4 are denoted by the same reference numerals, and detailed description thereof is omitted.

  Unlike the first embodiment, this embodiment differs from the first embodiment in that when communication is established between the detection unit 10 and the alarm unit 11 that are turned on, the detection unit 10 is measured by the sensor unit 100. A measurement value signal representing a value is transmitted, and the alarm unit 11 that has received the measurement value signal determines whether or not alarm notification is necessary. Details of the operation of the alarm device 1 of the present embodiment that operates in this way will be described below with reference to the flowcharts of FIGS. 5 and 6, focusing on the operations different from those of the first embodiment.

  As in the first embodiment, after the power is turned on, the detection unit 10 transmits the confirmation signal generated by the first control unit 101 from the first communication unit 102 to the alarm unit 11 (S1 to S3). On the other hand, when the alarm unit 11 enters a standby state after power-on, the second control unit 111 confirms reception of the transmission signal from the detection unit 10 in the second communication unit 110 (S11 to S13). When the second communication unit 110 receives a transmission signal from the detection unit 10 (Yes in S13), the second control unit 111 determines whether the received signal is a measurement value signal (S111). At this time, when the second communication unit 110 receives the confirmation signal transmitted from the detection unit 10 (No in S111), the response signal generated by the second control unit 111 is sent from the second communication unit 110 to the detection unit 10. Transmit (S15). Thereby, communication between the detection unit 10 and the alarm unit 11 is established.

  When communication between the detection unit 10 and the alarm unit 11 is established, the detection unit 10 is provided with the environmental value measured by the sensor unit 100 to the first control unit 101 as in the first embodiment. The first control unit 101 starts measuring time with a timer (not shown) (S4, S5). And the 1st control part 101 which acquired the electric signal which shows environmental value from the sensor part 100 produces | generates the measured value signal which represents this environmental value, and transmits to the warning part 11 from the 1st communication part 102 (S101). Thereafter, the first control unit 101 confirms whether or not the first communication unit 102 has received a notification confirmation signal indicating that the alarm unit 11 has started the notification operation (S102). At this time, if the first communication unit 102 has not received the notification confirmation signal from the alarm unit 11 (No in S102), the detection unit until the elapse of a predetermined time is confirmed by the measurement result of a timer (not shown). 10 standby states are maintained (S7, S8).

  In addition, in the detection part 10, after communication with the alarm part 11 is established, until the measurement value signal by S101 is transmitted, the power supply to the first communication part 102 is stopped to suppress power consumption. It is good. At this time, the first communication unit 102 that has transmitted the measurement value signal in S101 is operated for a predetermined time to wait for the reception of the notification confirmation signal from the alarm unit 11, and whether or not the notification confirmation signal has been received is determined. Then, the power supply to the first communication unit may be stopped again. In this way, by using a configuration in which power is supplied to the first communication unit 102 only when communication is necessary, the power consumption in the detection unit 10 of the alarm device 1 can be reduced.

  Also in this embodiment, after the detection unit 10 receives the notification confirmation signal by the first communication unit 102 and confirms that the alarm unit 11 has started the notification operation (Yes in S102), it is not illustrated. However, it is restored by the same operation as in the first embodiment. That is, it may be restored by operating the detection unit 10 itself, or may be restored by giving an instruction through communication with the alarm unit 11. Further, when the detection unit 10 itself is operated and recovered, communication with the alarm unit 11 may be performed to give an instruction for recovery to the alarm unit 11.

  On the other hand, the alarm unit 11 having established communication with the detection unit 10 confirms reception of the signal by the second communication unit 110 when the measurement value signal is transmitted from the detection unit 10 (Yes in S13). The second control unit 111 recognizes that the received signal is a measurement value signal (Yes in S111). When the measurement value signal received by the second communication unit 110 is given to the second control unit 111, the second control unit 111 supplies power to a circuit portion for determining whether the notification operation is required by the notification unit. The determination operation is started (S112). Then, the second control unit 111 recognizes the environmental value measured by the sensor unit 100 based on the measurement value signal, and determines whether or not the environmental value has reached the warning range, thereby performing the notification operation. The necessity is determined (S113).

  When the environmental value measured by the sensor unit 100 has not reached the alarm range (No in S113), the second control unit 111 performs a determination operation in order to determine that the notification operation by the notification unit is unnecessary. The power supply of the part is stopped, and a transition is made to a standby state for receiving the measurement value signal from the detection unit 10 (S13). On the other hand, when the environmental value measured by the sensor unit 100 has reached the alarm range (Yes in S113), the second control unit 111 performs the sounding body 112 and the display unit 113 in order to perform a notification operation by the notification unit. The power supply to each part for performing the notification operation is started (S16). Then, an alarm notification operation is started by issuing an alarm by the sounding body 112 or displaying an alarm by the display unit 113 (S17).

  Thereafter, the second control unit 111 generates a notification confirmation signal indicating that the alarm notification operation has started, and transmits the notification confirmation signal from the second communication unit 110 to the detection unit 10 (S114). Thereby, the detection part 10 can recognize the start of the alerting | reporting operation | movement in the alarm part 11 by receiving a alerting | reporting confirmation signal as mentioned above. The alarm unit 11 is also restored by the same operation as in the first embodiment, although not shown, after the notification operation is started and the notification confirmation signal is transmitted (S17, S114). That is, it may be restored by operating the alarm unit 11 itself, or may be restored by giving an instruction through communication with the detection unit 10. Further, when the alarm unit 11 itself is operated and recovered, communication with the detection unit 10 may be performed, and a recovery instruction may be given to the detection unit 10.

  As described above, in the present embodiment, since the alarm unit 11 determines whether or not alarm notification is necessary, the detection unit 10 can perform only the environmental value measurement operation. The circuit constituting the control unit 101 can be made small, and the detection unit 10 can be reduced in size and power consumption. Also in the alarm unit 11, the power supply of the circuit components for performing the determination operation is stopped until the measurement value signal is received, so that the power consumption is suppressed.

<Third Embodiment>
The alarm device of the 3rd Embodiment in this invention is demonstrated with reference to drawings. FIG. 7 is a flowchart showing the operation of the detection unit of the alarm device in this embodiment, and FIG. 8 is a flowchart showing the operation of the alarm unit of the alarm device in this embodiment. In the operation steps shown in FIGS. 7 and 8, the same operation steps as those shown in the flowcharts of FIGS. 5 and 6 are denoted by the same reference numerals, and detailed description thereof is omitted.

  Unlike the second embodiment, the present embodiment notifies the alarm after the alarm unit 11 that has received the measurement value signal from the detection unit 10 determines that the measured environmental value has reached the preliminary alarm range. The necessity of alarm notification is determined in a plurality of stages so as to determine the arrival of the alarm area for the purpose. In the detection unit 10, the measurement timing by the sensor unit 100 until the measured environmental value reaches the preliminary alarm range, and the measurement timing by the sensor unit 100 after the measured environmental value reaches the preliminary alarm range To change. Details of the operation of the alarm device 1 of the present embodiment that operates in this manner will be described below with reference to the flowcharts of FIGS. 7 and 8, focusing on the operations different from those of the second embodiment.

  As in the second embodiment, when each of the detection unit 10 and the alarm unit 11 is powered on, the detection unit 10 transmits a confirmation signal to the alarm unit 11 and receives the confirmation signal. Transmits a response signal to the detection unit 10 to establish communication between the detection unit 10 and the alarm unit 11 (S1 to S3 in FIG. 7, S11 to S13, S111, and S15 in FIG. 8). . When the connection between the detection unit 10 and the alarm unit 11 is established, the detection unit 10 initializes the elapsed time measured by a timer (not shown) as the predetermined time T1 in the first control unit 101. (S201). That is, the first control unit 101 sets the elapsed time measured by a timer (not shown) to the predetermined time T1 so that the sensor unit 100 measures the environmental value every predetermined time T1.

  Thereafter, in the detection unit 10, as in the first embodiment, after the sensor unit 100 measures the environmental value and gives it to the first control unit 101, the first control unit 101 performs time measurement using a timer (not shown). And a measurement value signal representing the measured environmental value is transmitted from the first communication unit 102 (S4, S5, S101). Thus, the detection part 10 which transmitted the measured value signal to the alarm part 11 confirms the presence or absence of reception of the transmission signal from the alarm part 11 in the 1st communication part 102 (S202). When the first communication unit 102 does not receive the measurement value signal (No in S202), the standby state of the detection unit 10 is maintained until the elapse of a predetermined time is confirmed by the measurement result of a timer (not shown). (S7, S8).

  In the operation steps of S7 and S8, after the communication with the alarm unit 11 is established, if the elapsed time is set by the predetermined time T1, the passage of the predetermined time T1 is confirmed after the measurement by the sensor unit 100. . As will be described later, when the environmental value measured by the sensor unit 100 reaches the preliminary alarm range, the alarm unit 11 notifies the fact that the elapsed time is a predetermined time T2 (T2 <T1). In the operation steps of S7 and S8, the passage of the predetermined time T2 is confirmed after the measurement by the sensor unit 100.

  On the other hand, in the alarm unit 11, when the second control unit 111 confirms that the transmission signal from the detection unit 10 received by the second communication unit 110 is a measurement value signal (Yes in S111), the second control unit 111. Starts a determination operation based on the environmental value confirmed from the measurement value signal (S112). Then, the second control unit 111 confirms whether or not the determination operation using the measurement value signal is the main determination for determining whether or not the alarm area is reached (S211). At this time, when it is not the determination operation by this determination (No in S211), the second control unit 111 confirms whether or not the environmental value confirmed from the measurement value signal has reached the preliminary alarm range (S212). For example, when the environmental value is the smoke amount, the second control unit 111 determines that the preliminary warning area has been reached when the smoke amount represented by the measurement value signal exceeds the threshold Th1, and the measurement value signal It is determined that the warning area has been reached when the amount of smoke that has appeared exceeds a threshold Th2 (Th2> Th1).

  And if the 2nd control part 111 confirms that the environmental value confirmed from the measured value signal reached | attained the preliminary warning area (Yes in S212), in order to make the measurement timing of the environmental value in the detection part 10 into a short time. Is generated and transmitted from the second communication unit 110 (S213). At this time, the second control unit 111 sets a flag for storing that the determination operation for the measurement value signal received from the next time is performed by the main determination when the preliminary alarm range is reached. In response to the time change instruction signal transmitted in the operation step of S213, the detection unit 10 changes the elapsed time measured by a timer (not shown) from the predetermined time T1 to the predetermined time T2. After transmitting this time change instruction signal, the alarm unit 11 is in a standby state until it receives a measurement value signal from the detection unit 10 (S12). Even when the environmental value confirmed from the measurement value signal does not reach the preliminary alarm range (No in S212), the alarm unit 11 is in a standby state until receiving the measurement value signal from the detection unit 10 ( S12).

  By operating in this way, until the environmental value reaches the preliminary alarm range, the detection unit 10 transmits a measurement value signal based on the environmental value measured every predetermined time T1 to the alarm unit 11, and the alarm unit 11 confirms whether or not the preliminary warning area has been reached. When the environmental value reaches the preliminary alarm range, a time change instruction signal for changing the environmental value measurement timing to a short time is transmitted from the alarm unit 11 to the detection unit 10. When the environmental value reaches the preliminary alarm range, the alarm unit 11 transmits a time change instruction signal and also reports by the sounding body 112 or by the display unit 113 to indicate that the preliminary alarm range has been reached. It is good also as what displays and notifies a preliminary alarm outside.

  When the alarm unit 11 transmits a time change instruction signal for changing the predetermined time T1 to the predetermined time T2, the detection unit 10 causes the first communication unit 102 to perform a signal reception operation (Yes in STEP 202). ), The first control unit 101 confirms the type of signal received by the first communication unit 102 (S203, S204). At this time, since the first control unit 101 confirms that the time change instruction signal has been received (No in S203, Yes in S204), the elapsed time for determining the measurement timing by the sensor unit 100 is changed by the time change instruction signal. Is changed to the predetermined time T2 instructed (S205). Thereafter, the standby state is maintained until the changed predetermined time T2 after the environmental value is measured by the sensor unit 100 (S7, S8).

  As described above, the detection unit 10 receives the time change instruction signal, so that the first control unit 101 changes the elapsed time for determining the measurement timing to the predetermined time T2 shorter than the predetermined time T1, and this predetermined time. The environmental value is measured by the sensor unit 100 every T2. Therefore, the measurement value signal transmitted from the detection unit 10 is transmitted to the alarm unit 11 every predetermined time T2. At this time, in the alarm unit 11, when the second communication unit 110 receives the measurement value signal (Yes in S13, Yes in S111), the second control unit 111 prepares the determination operation, and the current determination operation is the main determination. (Yes in S112 and S211). Therefore, as in the second embodiment, the second control unit 111 determines whether or not the environmental value based on the measurement value signal has reached the alarm range (S113).

  When the environmental value measured by the sensor unit 100 has not reached the alarm range (No in S113), in the present embodiment, the second control unit 111 further determines that the environmental value based on the measurement value signal is outside the preliminary alarm range. Whether or not it is necessary to return from the main determination to the determination in the preliminary alarm range (preliminary determination) is determined (S214). For example, as described above, when the environmental value is the smoke amount and the threshold values in the preliminary determination and the main determination are Th1 and Th2, the second control unit 111 determines that the smoke amount represented by the measurement value signal is the threshold Th1. When the value is lower, it is determined that it is necessary to return from the main determination to the preliminary determination.

  Then, when the second control unit 111 determines that it is necessary to return to the preliminary determination (Yes in S214), the second control unit 111 generates a return instruction signal indicating that the preliminary determination is returned. Then, the data is transmitted from the second communication unit 110 to the detection unit 10 (S215). Thereafter, the alarm unit 11 enters a standby state in order to receive the measurement value signal from the detection unit 10 (S12). At this time, the second control unit 111 resets a flag indicating that the main determination is performed, and stores that the preliminary determination is performed. The return instruction signal transmitted from the second communication unit 110 to the detection unit 10 includes a command to change the elapsed time for determining the environmental value measurement timing to a predetermined time T1 longer than the predetermined time T2. In addition, when the environmental value based on the measurement value signal remains in the preliminary alarm range and it is necessary to make this determination continuously (No in S214), the alarm unit 11 outputs the measurement value signal from the detection unit 10. A standby state is entered for reception (S12).

  On the other hand, when the alarm unit 11 transmits the return instruction signal in the operation step of S215, the detection unit 10 confirms that the signal received by the first control unit 101 by the first communication unit 102 is the return instruction signal. (Yes in S202, No in S203, No in S204). Accordingly, the first control unit 101 confirms that the alarm unit 11 has determined that the environmental value is out of the preliminary alarm range, and in accordance with the command included in the received return instruction signal, the first control unit 101 determines the environmental value measurement timing. Is changed from the predetermined time T2 to the predetermined time T1 (S206). Thereafter, the standby state is maintained until the changed predetermined time T1 after the environmental value is measured by the sensor unit 100 (S7, S8).

  Thereby, in the detection unit 10, when the return instruction signal is received from the alarm unit 11, the sensor unit 100 measures the environmental value every predetermined time T1, and the measurement value signal based on the environmental value is transmitted to the first communication unit 102. Send more. In the alarm unit 11 that has transmitted the return instruction signal, the second communication unit 110 receives the measurement value signal transmitted from the detection unit 10 every predetermined time T1, and in the operation step of S212, the environment based on the measurement value signal is received. The second control unit 111 determines whether or not the value has reached the preliminary alarm range.

  Further, when the alarm unit 11 confirms that the environmental value measured by the sensor unit 100 has reached the alarm range (Yes in S113), as in the second embodiment, the alarm unit 11 sends information to each unit for performing the notification operation. After the power supply is started, an alarm notification operation is started by issuing an alarm by the sounding body 112 or displaying an alarm by the display unit 113 (S16, S17). Thereafter, the alarm unit 11 transmits a notification confirmation signal to the detection unit 10 (S114), and the detection unit 10 receives the notification confirmation signal from the alarm unit 11 and recognizes the start of the notification operation in the alarm unit 11. (Yes in S202, Yes in S203). Also in the present embodiment, after the notification operation in the alarm unit 11 is started, each of the detection unit 10 and the alarm unit 11 is restored by the same operation as in the first and second embodiments.

  In this embodiment, the alarm unit 11 performs both the preliminary determination and the main determination. However, after the preliminary determination is performed by the detection unit 10, only the main determination may be performed by the alarm unit 11. . That is, when communication is established between the detection unit 10 and the alarm unit 11, in the detection unit 10, the first control unit 101 determines that the environmental value measured by the sensor unit 100 is a preliminary alarm every predetermined time T1. A preliminary determination is made as to whether or not the zone has been reached. Then, when it is confirmed from the result of the preliminary determination that the environmental value has reached the preliminary warning range, a measurement value signal based on the environmental value measured by the sensor unit 100 is transmitted from the first communication unit 102 at every predetermined time T2. It is transmitted to the alarm unit 11. Therefore, the alarm unit 11 performs a main determination to determine whether or not the environmental value based on the received measurement value signal has reached the alarm range, and performs an alarm notification operation when confirming that the alarm range has been reached. Furthermore, the detection unit 10 may perform both the preliminary determination and the main determination.

  In each of the above-described embodiments, the number of times the alarm area has been reached for the determination by the first control unit 101 in S6 (see FIG. 3) and the determination by the second control unit 111 in S113 (see FIGS. 6 and 8). The alarm area may be reached only after a predetermined number of consecutive times, and it may be determined that an alarm notification operation is necessary. That is, it is determined that an alarm notification operation is necessary only when the detection unit 10 continuously measures an environmental value exceeding a threshold value that is an alarm range for a predetermined number of times, and the alarm unit 11 performs an alarm notification operation. I do. Furthermore, in the third embodiment, the determination by the second control unit 111 in S214 may be made to return to the preliminary determination only when the number of times of going out of the preliminary alarm range continues for a predetermined number of times.

  In each of the above-described embodiments, the relationship between the detection unit 10 and the alarm unit 11 constituting the alarm device 1 is assumed to be a one-to-one relationship as in the basic configuration illustrated in FIGS. 1 and 2. The relationship between the unit 10 and the alarm unit 11 may be a one-to-multiple relationship or a multiple-to-one relationship. And in the alarm device in which the detection unit 10 and the alarm unit 11 have a one-to-multiple relationship or a multiple-to-one relationship, the communication operation between the detection unit 10 and the alarm unit 11, For the control operation in each of the alarm units 11, the operations described in the first to third embodiments can be applied. Therefore, in the following first to third embodiments, the configuration of the alarm device and the outline of the communication operation in which the detection unit 10 and the alarm unit 11 have a one-to-multiple relationship or a multiple-to-one relationship will be described.

  An embodiment having the configuration shown in FIG. 9 will be described as a first embodiment other than the alarm device having the basic configuration shown in FIG. As shown in FIG. 9, the alarm device 1 a according to the present embodiment includes one detection unit 10 and a plurality of alarm units 11 that communicate with the detection unit 10. And each internal structure of this detection part 10 and the some alarm part 11 is an internal structure similar to the detection part 10 and the alarm part 11 which are shown in FIG. Is connected to a wired or wireless communication line.

  As described in the first to third embodiments, the alarm device 1a having such a configuration transmits a confirmation signal from the detection unit 10 when each of the detection unit 10 and the alarm unit 11 is powered on. At the same time, a response signal is transmitted from each of the plurality of alarm units 11, thereby establishing communication between the detection unit 10 and the alarm unit 11. Even after communication with one or more alarm units 11 is established, the detection unit 10 performs measurement by the sensor unit 100 and transmits a confirmation signal at the same time, so that the detection unit 10 can enter the communication network. Communication with the alarm unit 11 newly installed can be established.

  In addition, the alarm unit 11 transmits a confirmation signal to request the establishment of communication to the detection unit 10, and the detection unit 10 transmits a response signal to the alarm unit 11, thereby permitting establishment of communication. It may be given to the alarm unit 11. Note that the configuration in which the detection unit 10 transmits a response signal and establishes communication after transmitting a confirmation signal from the alarm unit 11 can also be applied to the above-described first to third embodiments.

  Thus, when communication is established between the detection unit 10 and the plurality of alarm units 11, either the notification request signal or the measurement value signal is simultaneously transmitted from the detection unit 10 to the plurality of alarm units 11. The Therefore, when a notification request signal is transmitted from the detection unit 10, a plurality of alarm units 11 having different installation positions simultaneously receive the notification request signal and start a notification operation at the same time. When a measurement value signal is transmitted from the detection unit 10, a plurality of alarm units 11 having different installation positions simultaneously receive the measurement value signal and determine whether a notification operation is necessary. At this time, since the alarm unit 11 determines whether or not the notification operation is necessary, the threshold value serving as the alarm area can be set to a different value depending on the installation position. Therefore, when the measurement value signal is transmitted from the detection unit 10, only the alarm unit 11 that has determined that the notification operation is necessary starts the notification operation.

  As a second embodiment, an embodiment having the configuration shown in FIG. 10 will be described. As shown in FIG. 10, unlike the alarm device 1a of the first embodiment shown in FIG. 9, the alarm device 1b of the present embodiment has a configuration in which only the alarm portion 11a can communicate with the detection portion 10, and a plurality of other alarm devices. The unit 11b communicates with the alarm unit 11a. In addition, each internal structure of the detection part 10 and alarm part 11a, 11b is an internal structure similar to the detection part 10 and alarm part 11 shown in FIG. 2, and between the detection part 10 and the alarm part 11 is shown. A wired or wireless communication line is connected.

  In the alarm device 1b having such a configuration, measurement of an environmental value by the sensor unit 100 is started in the detection unit 10 after communication is established between the detection unit 10 and the alarm unit 11a. At this time, the confirmation signal may be transmitted from the detection unit 10 to establish communication, or as described in the first embodiment, the confirmation signal is transmitted from the alarm unit 11a to establish communication. Also good.

  A communication network is also established between the alarm unit 11a and the alarm unit 11b. When a confirmation signal is transmitted from the alarm unit 11a to the alarm unit 11b and a response signal is received from the alarm unit 11b, communication is performed. The alarm unit 11a may recognize the alarm unit 11b that has joined the network. Conversely, when the alarm unit 11b participating in the communication network constructed by the alarm unit 11a transmits a confirmation signal to the alarm unit 11a and the alarm unit 11b receives a response signal from the alarm unit 11a, the alarm unit 11a Communication may be established with the alarm unit 11b.

  In this way, in the alarm device 1b of the present embodiment, communication is established between the detection unit 10 and the alarm unit 11a, and communication is established between the alarm unit 11a and the plurality of alarm units 11b. It will be. Therefore, unlike the first embodiment, the notification request signal or the measurement value signal from the detection unit 10 is transmitted only to the alarm unit 11a. When the detection unit 10 transmits the notification request signal to the alarm unit 11a, the alarm unit 11a that has received the notification request signal starts the notification operation and simultaneously transmits the notification request signal to the plurality of alarm units 11b. Send. Thereby, when the notification request signal is transmitted from the detection unit 10, the alarm unit 11a and the plurality of alarm units 11b can start the notification operation almost simultaneously.

  On the other hand, when the detection unit 10 transmits the measurement value signal to the alarm unit 11a, the alarm unit 11a determines whether the notification operation is necessary. When the warning unit 11a determines that the notification operation is necessary, the second control unit 111 generates a notification request signal, and the second communication unit 110 generates the notification request signal from the plurality of alarm units 11b. Send to. When this notification request signal is transmitted to the alarm unit 11b, the alarm unit 11a starts a notification operation by the notification unit. Each of the plurality of alarm units 11b that has received the notification request signal from the alarm unit 11a by the second communication unit 110 also starts the notification operation by the notification unit. Thereby, since it can be set as the structure which determines the necessity of alerting | reporting operation only by the alarm part 11a, the low power consumption of the alarm part 11b can be achieved.

  Furthermore, as Example 3, an example with the configuration shown in FIG. 11 will be described. As shown in FIG. 11, the alarm device 1 c of this embodiment includes a plurality of detection units 10 and a single alarm unit 11 that communicates with the plurality of detection units 10. And each internal structure of the some detection part 10 and the warning part 11 is the internal structure similar to the detection part 10 and the warning part 11 shown in FIG. A wired or wireless communication line is connected.

  In the alarm device 1c having such a configuration, after communication is established between the plurality of detection units 10 and the alarm unit 11, measurement of environmental values by the sensor unit 100 is started in each of the plurality of detection units 10. . At this time, communication may be established by transmitting a confirmation signal from the detection unit 10, or communication may be established by transmitting a confirmation signal from the alarm unit 11 as described in the first embodiment. Also good. In addition, each of the plurality of detection units 10 measures the environmental value by the sensor unit 100 in order from the communication with the alarm device 11 established.

  And the alarm part 11 can prevent the collision of the signal transmitted from the several detection part 10 by managing the transmission timing of the notification request signal or measurement value signal transmitted from each of the several detection part 10 . In order to prevent collision of transmission signals from the plurality of detection units 10, the alarm unit 11 may transmit a signal permitting measurement of the environmental value to each of the detection units 10 with which communication has been established. Good. That is, the measurement timing of each of the plurality of detection units 10 is managed by one alarm unit 11. Thereby, not only the notification request signal or the measurement value signal transmitted from each of the plurality of detection units 10 can be prevented from colliding, but the alarm unit 11 can grasp the detection unit 10 that has transmitted the signal.

  In the present embodiment, it is preferable that the detection unit 10 determines whether or not the alarm notification is necessary, and the notification request signal is transmitted from the detection unit 10 to the alarm unit 11 as in the first embodiment. By performing the control operation of the first embodiment, the alarm unit 11 can be configured to perform many operations only when receiving the notification request signal. That is, until the notification request signal is received, the alarm unit 11 can be set in a standby state, so that the power consumption can be reduced. Further, when the alarm notification operation is started by the alarm unit 11, it is preferable to notify which detection unit 10 the measurement result is.

  The present invention is also applicable to a fire alarm device that notifies a fire alarm by detecting smoke or heat, a gas sensor alarm device that notifies a gas alarm, and a human body detection alarm device that detects a human body. Can do.
