Next, specific contents of the embodiment will be described.

(Constitution)
First, the configuration of the optical alarm system according to the present embodiment will be described. FIG. 1 is an overall view showing an optical alarm system according to the present embodiment.

  The light alarm system 900 in FIG. 1 is a disaster prevention system, specifically, an alarm system, and includes, for example, a plurality of light alarms 1 and a light control device 2. The number of optical alarms 1 connected to the light control device 2 is arbitrary, but here, for example, three optical alarms 1 are shown. Further, since the configuration of each of the plurality of optical alarms 1 is similar to each other, one optical alarm 1 will be described as a representative. FIG. 1 illustrates a case in which the light control device 2 is connected to the light alarm device 1. The light control device 2 is connected to the light alarm device 1 based on control from a disaster prevention receiver (not shown). The following describes an example in which various signals are transmitted and controlled.

(Configuration-Optical alarm)
FIG. 2 is a circuit diagram of the optical alarm. The optical alarm device 1 is an alarm device, and specifically, is a device that emits an alarm by outputting a flash light and issues an alarm. For example, a management terminal T1, a power supply terminal T2, a ground terminal T3, a control unit 11, a capacitor 12, a light emitting diode 13, a resistor 14, a first switch 15, a second switch 16, a first diode 17, and a second diode 18.

(Configuration-Optical alarm-Terminal)
The management terminal T1 is a terminal to which an electric signal (electric power) is input when the optical alarm 1 is set to the management mode, for example, a terminal electrically connected to the light control device 2 side. is there. The power supply terminal T2 is, for example, a terminal to which an electric signal (electric power) is input when the optical alarm 1 is set to the non-management mode. As an example, the power supply terminal T2 is electrically connected to the light control device 2 side. Terminal. The ground terminal T3 is, for example, a terminal on the ground side, and is, for example, a terminal electrically connected to the light control device 2 side.

(Configuration-Optical alarm-Control unit)
The control unit 11 is a control unit that controls the optical alarm device 1. Specifically, the control unit 11 includes a CPU, various programs interpreted and executed on the CPU (a basic control program such as an OS, and a specific program activated and specified on the OS). And an internal memory such as a RAM for storing programs and various data. In particular, the program according to the embodiment substantially installs each unit of the control unit 11 by being installed in the optical alarm 1 via an arbitrary recording medium or a network.

  The control unit 11 functions as, for example, an output unit and a determination unit in a functional concept. Specific processing performed by each unit of the control unit 11 will be described later.

(Configuration-Optical alarm-Each element)
The capacitor 12 is a power storage unit that is charged with power. For example, the capacitor 12 is charged with power for causing the light emitting diode 13 to emit light. The light emitting diode 13 is a light emitting unit that emits light, specifically, an LED (Light Emitting Diode), and emits light by the power of the capacitor 12, for example. The resistor 14 is a changing unit that changes the power consumption of the optical alarm 1, and is, for example, an electric resistor. The first switch 15 is first opening / closing means whose opening / closing is controlled by the control unit 11, and is, for example, an opening / closing switch for electrically opening / closing between the management terminal T1 and the resistor 14. The second switch 16 is second opening / closing means whose opening / closing is controlled by the control unit 11, and is, for example, an opening / closing switch for electrically opening / closing between the capacitor 12 and the light emitting diode 13. The first diode 17 is rectifying means for rectifying between the management terminal T1 and the capacitor 12. The second diode 18 is rectifying means for rectifying between the power supply terminal T2 and the capacitor 12.

(Configuration-Light control device)
The light control device 2 in FIG. 1 is an alarm control device. The specific type and configuration of the light control device 2 are arbitrary. For example, the light control device 2 supplies electric power (electric signal) to the light alarm device 1 and has the same control as the control unit 11 of the light alarm device 1. And the like.

(processing)
Next, a control process configured as described above and executed by the light alarm system 900 will be described. FIG. 3 is a flowchart of the control process (steps are abbreviated as “S” in the following description of each process), and FIG. 4 is a diagram exemplifying an electric signal output by the light control device. 1 illustrates an electric signal including a pulse, and FIG. 2B illustrates an electric signal including no pulse. The “control process” is a process that is executed by the optical alarm 1 of the optical alarm system 900, specifically, a process that controls the optical alarm 1. The timing at which this control process is performed is arbitrary. For example, when the control terminal 11 receives an electric signal at the management terminal T1 or the power supply terminal T2 and the power of the electric signal is supplied to the control unit 11, the control unit 11 is started. The execution is started from the point where the execution is started.

  The CPU of the control unit 11 in FIG. 2 is electrically connected to the management terminal T1 and the power supply terminal T2 via a known electric circuit including, for example, a regulator circuit and the like. A description will be given below assuming that when an electric signal is supplied to T2, the operation is performed based on the power of the electric signal. In FIG. 2, a known electric circuit including the regulator circuit and the like is not shown for convenience of description. Further, for example, in each terminal of the optical alarm device 1 of FIG. 2, the ground terminal T3 is grounded via the light control device 2, and an electric signal is input from the light control device 2 to the management terminal T1 or the power supply terminal T2. An example will be described. Further, it is assumed that the first switch 15 and the second switch 16 are in an open state as illustrated when the control process is started.

  In SA1 of FIG. 3, the control unit 11 determines whether to set the management mode as its own operation mode. Specifically, for example, as shown by a thin-line arrow in FIG. 2, the control unit 11 controls the voltage of the management terminal T1 (the voltage on the anode side of the first diode 17) and the voltage of the power supply terminal T2. (The voltage on the anode side of the second diode 18) can be monitored. Based on the monitoring result, it is determined which terminal the electric signal is input to, and based on the determination result, It is determined whether to set the management mode as its own operation mode. When the light control device 2 supplies an electric signal to the power supply terminal T2, it is determined that the electric signal has been input to the power supply terminal T2, and it is determined that the management mode is not set as its own operation mode ( (NO in SA1) After setting the non-management mode, the process proceeds to SA4. When the light control device 2 supplies an electric signal to the management terminal T1, it is determined that the electric signal has been input to the management terminal T1, and it is determined that the management mode is set as its own operation mode (SA1). YES), set the management mode, and then proceed to SA2.

  Here, for example, when operating the optical alarm 1 in the non-management mode in the same manner as in the related art, the light control device 2 supplies the electric signal of FIG. 4A or FIG. 4B to the power supply terminal T2. I do. In this case, the control unit 11 of the optical alarm 1 determines that the electric signal has been input to the power supply terminal T2, determines that the management mode is not set as its own operation mode (NO in SA1), Set the management mode. Further, for example, when operating the optical alarm 1 in the management mode, the light control device 2 supplies the electric signal of FIG. 4B to the management terminal T1. In this case, the control unit 11 of the optical alarm device 1 determines that the electric signal has been input to the management terminal T1, determines that the management mode is set as its own operation mode (YES in SA1), and Set.

  In SA2 of FIG. 3, the control unit 11 performs management related to charging of the capacitor 12. More specifically, for example, an operation test is performed with the second switch 16 opened so that the light emitting diode 13 does not emit light. The “operation test” is a test for determining the state of the optical alarm device 1. For example, regarding the charging speed or the maximum charge capacity of the capacitor 12, the optical alarm device 1 is in a normal state or an abnormal state (predetermined state). This is a test for determining whether or not the above condition is satisfied. More specifically, the capacitor 12 is charged by the electric signal of FIG. 4B supplied to the management terminal T1, and a change in the voltage generated in the capacitor 12 with respect to the elapsed time is detected to specify the charging speed of the capacitor 12. Alternatively, the maximum voltage generated in the capacitor 12 is detected, and the maximum charging capacity of the capacitor 12 is specified. A method in which when both are within a predetermined reference range, it is determined to be in a normal state, and when at least one of the specified values is out of the reference range, it is determined to be in an abnormal state. The operation test is performed by determining whether the state is a normal state or an abnormal state. In this case, for example, a case may be assumed in which the operation test is repeatedly performed on the capacitor 12 a plurality of times to make a determination. In this case, it is necessary to repeatedly charge and discharge the capacitor 12. Without repeating, a third switch (not shown) having one end connected between the capacitor 12 and the first diode 17 and the other end connected to the ground terminal T3 in order to repeatedly charge and discharge the capacitor. A configuration may be provided in which the capacitor 12 is charged while the third switch is open, and the capacitor 12 is discharged by closing the third switch. In this case, when the third switch is closed, the management terminal T1 and the ground terminal T3 are prevented from being short-circuited by the optical alarm device 1 by a known method (such as providing an electric resistance at an arbitrary position). You may. Note that the control of the opening and closing of the third switch is also executed by the control unit 11.

  In SA3 of FIG. 3, the control unit 11 outputs the result of the management performed in SA2, and ends the process. Specifically, for example, in order to prevent the light emitting diode 13 from emitting light, in a state where the second switch 16 is opened, the result of the operation test of SA2 is transmitted to the optical alarm which is the electrical state of the optical alarm 1. It outputs according to the change in the power consumption of the device 1. More specifically, when it is determined in SA2 that the capacitor 12 is in a normal state, the first switch 15 in FIG. 2 is kept open and the power consumption of the optical alarm 1 is not changed. It outputs that the device 1 is determined to be in a normal state (that is, not determined to be in an abnormal state). When it is determined in SA2 that the optical alarm device 1 is in an abnormal state, the first switch 15 in FIG. 2 is closed to change (increase) the power consumption of the optical alarm device 1. Is output. In such a configuration, by monitoring the power consumption of the optical alarm device 1 on the light control device 2 side in FIG. 1, it is determined that the optical alarm device 1 is in a normal state as a result of the management related to the charging of the capacitor 12. It is possible to determine whether the determination is made or whether the state is abnormal.

  Note that the expressions “do not change the power consumption” and “change the power consumption” actually mean that the power consumption of the optical alarm 1 depends on the operation state of the CPU of the control unit 11 and the like. It is a concept that slightly changes or does not consider this slight change. More specifically, “do not change the power consumption” is a concept corresponding to, for example, not changing the power consumption as much as closing the first switch 15 so that the current flows to the resistor 14 side. The concept of “changing power consumption” is a concept based on a similar viewpoint, and corresponds to, for example, changing the first switch 15 to cause a relatively large change by flowing a current to the resistor 14 side. It is a concept. Then, the light control device 2 in FIG. 1 compares the power consumption of the light alarm device 1 with a predetermined threshold value, and as a result of the management related to the charging of the capacitor 12, the light alarm device 1 is in a normal state. It is possible to determine whether it has been determined that there is a certain condition or an abnormal condition.

  On the other hand, in SA1 of FIG. 3, it is determined that the management mode is not set as its own operation mode (NO in SA1), and in SA4 after setting the non-management mode, the control unit 11 causes the light emitting diode 13 to emit light. Alarm. Specifically, it is arbitrary, and a warning is issued by emitting light using a conventional method. Here, only an outline will be described. For example, when an electric signal including a light emission synchronization signal (a signal for synchronizing the optical alarm 1 from the outside), which is a pulse shown in FIG. 4A, is input to the power supply terminal T2, the timing of the pulse is applied. By closing the second switch 16 for a moment and instantaneously supplying current from the capacitor 12 to the light emitting diode 13, the light emitting diode 13 outputs flash light. Further, when an electric signal that does not include the light emission synchronization signal, which is the pulse of FIG. 4B, is input to the power supply terminal T2, the timing at which the electric signal is input (that is, the electric signal changes from a low level At a predetermined time interval using its own timer, the second switch 16 is momentarily closed to instantaneously apply a current from the capacitor 12 side to the light emitting diode 13 on the basis of the electric signal transmission start timing that changes to a high level). As a result, the flash light is output from the light emitting diode 13. Then, when the transmission of the electric signal from the light control device 2 ends, the output of the flash light ends. Thus, the control process is completed.

(Effects of Embodiment)
As described above, according to the present embodiment, by changing the electrical state of the optical alarm device 1 to output the fact that the predetermined state is an abnormal state, for example, the abnormal state can be determined. It is possible to output. In addition, for example, it is possible to output that an abnormal state has occurred without causing the light alarm device 1 to emit light, so that it is possible to prevent annoyance to a nearby user.

  In addition, by outputting the fact that the optical alarm device 1 is in an abnormal state by changing the power consumption thereof, for example, by grasping the power consumption of the optical alarm device 1, the optical alarm device 1 becomes in an abnormal state. Since it can be grasped, it can be easily grasped that an abnormal state has occurred.

  In addition, by determining whether or not an abnormal state has occurred, for example, it is possible to reliably output that an abnormal state has occurred.

[Modification to Embodiment]
As described above, the embodiments according to the present invention have been described. However, specific configurations and means of the present invention may be arbitrarily modified and improved within the technical idea of each invention described in the claims. Can be. Hereinafter, such modified examples will be described.

(About problems to be solved and effects of the invention)
First, the problems to be solved by the invention and the effects of the invention are not limited to the contents described above, and may differ depending on the implementation environment and details of the configuration of the invention. May be solved, or only a part of the effects described above may be achieved.

(About distribution and integration)
Further, the above-described configuration is conceptual in function, and does not necessarily need to be physically configured as illustrated. That is, the specific form of distribution and integration of each unit is not limited to the illustrated one, and all or a part thereof can be functionally or physically distributed or integrated in an arbitrary unit. Further, the “device” in the present application is not limited to a device configured by a single device, but includes a device configured by a plurality of devices.

(About the management mode setting)
Further, in the above-described embodiment, when an electric signal is input to the management terminal T1 in SA1 of FIG. 3, the optical alarm 1 is set to the management mode, and the electric signal is input to the power supply terminal T2. In this case, the case where the optical alarm 1 is set to the non-management mode in the above case has been described.

  For example, when an electric signal is input to the power supply terminal T2 and the electric signal includes a command for setting the management mode, the optical alarm 1 is set to the management mode. May be set to the non-management mode when an electric signal is input to the device and the electric signal does not include a command for setting the management mode. In this case, the management terminal T1 becomes unnecessary, so that the management terminal T1 may be omitted.

  Further, for example, the electric signal of FIG. 4B is input to the power supply terminal T2, and an arbitrary signal (for example, a positive single pulse or a burst signal) is set to the management mode at the management terminal T1. Is input as the management mode setting signal, the optical alarm 1 is set to the management mode, while the electric signal of FIG. 4B is input to the power supply terminal T2, and the management is performed to the management terminal T1. When the mode setting signal is not input, the optical alarm 1 may be set to the non-management mode.

(Management related to charging (Part 1))
Further, in the above-described embodiment, the case where the operation test related to the charging of the capacitor 12 is performed in SA2 of FIG. 3 has been described. However, instead of or together with the operation test, the optical alarm 1 is in the normal state. Alternatively, another determination may be made to determine whether the state is abnormal or abnormal. For example, when the control unit 11 has a function of detecting an unintended short circuit or disconnection at an arbitrary position in the electric circuit of the optical alarm device 1 and then detects the short circuit or the disconnection, an abnormal state occurs. May be performed, and when the short circuit or disconnection is not detected, a process of determining that the state is a normal state may be performed. Further, for example, similarly, a process of determining whether any other element of the optical alarm device 1 is in a normal state or an abnormal state may be performed.

(Management related to charging (Part 2))
Further, in the above embodiment, the case where the operation test is performed without emitting light in SA2 of FIG. 3 is exemplified. However, the present invention is not limited to this, and the light emitting diode 13 emits light by opening and closing the second switch 16 appropriately. An operation test may be performed.

(About output of information (1))
Further, in the above-described embodiment, the case where the power consumption of the optical alarm 1 is increased to output that the optical alarm 1 is in an abnormal state in SA3 of FIG. 3 is described, but the invention is not limited thereto. Instead, the fact that the optical alarm 1 is in an abnormal state may be output by reducing the power consumption of the optical alarm 1. In this case, specifically, the power consumption of the optical alarm 1 may be reduced by keeping the first switch 15 always closed and opening the first switch 15 when an abnormal state is determined. .

(About output of information (part 2))
Further, in the above-described embodiment, the plurality of optical alarm devices 1 of FIG. 1 are configured such that the amount of power consumption to be changed is different from each other, so that the optical alarm device 1 determined to be in an abnormal state can be uniquely identified. May be. In this case, each optical alarm 1 may be realized by making the resistance value of the resistor 14 different. In one optical alarm device 1, a plurality of resistors such as a resistor 14 are provided, and the resistance values of the plurality of resistors are made different from each other. Then, instead of the switch 15, a switch circuit such as a switch group or a relay circuit is provided. Is provided, and the control unit 11 controls the switching circuit, thereby switching the resistance electrically connected to the management terminal T1 among the plurality of resistances, and changing the power consumption of the optical alarm 1 in multiple stages. Accordingly, a plurality of predetermined states different from each other (for example, a normal state and an abnormal state, or a first abnormal state corresponding to a loss of capacity of a capacitor, a second abnormal state corresponding to a short circuit of a circuit, and disconnection of a circuit) (A third abnormal state).

(About information output (part 3))
Further, in the above-described embodiment, the case where information is output at SA3 in FIG. 3 according to a change in power consumption of the optical alarm 1 that is an electrical state of the optical alarm 1 has been described, but the present invention is not limited to this. . FIG. 5 is a circuit diagram of another optical alarm. The optical alarm 3 in FIG. 5 differs from the optical alarm 1 in FIG. 2 in that the switch 32 and the diode 33 are added after the first switch 15 and the resistor 14 are omitted. Then, as in the optical alarm 3 of FIG. 5, for example, a switch 32 and a diode 33 are provided between the power supply terminal T2 and the ground terminal T3, and the control unit 31 opens and closes the switch 32. Alternatively, information may be output by electrically opening and closing the power supply terminal T2 and the ground terminal T3. More specifically, when it is determined that the optical alarm 1 is in a normal state, the switch 32 is opened, and when it is determined that the optical alarm 1 is in an abnormal state, the switch 32 is opened. May be output in a closed state. In this case, when acquiring information, the light control device 2 applies a negative voltage to the power supply terminal T2, and supplies a current to the power supply terminal T2 from the ground terminal T3 via the diode 33 and the switch 32. By determining whether or not the alarm is performed, information that specifies whether the optical alarm 1 is in a normal state or in an abnormal state may be acquired. In the case of such a configuration, by electrically opening and closing a plurality of terminals of the optical alarm 3 to output an abnormal state which is a predetermined state, for example, the terminal of the optical alarm 3 is output. Since it is possible to grasp that a predetermined state has been attained by applying a voltage thereto, it is possible to easily grasp that a predetermined state has been attained.

(About indicator lights)
Further, the optical alarm may be provided with an indicator light for displaying an abnormal state. The indicator light may be displayed when an abnormality is detected, or may be displayed when a predetermined signal is input from the light control device.

  Further, the light control device may include an indicator light, and may turn on the indicator light when receiving a signal indicating that any of the optical alarms connected thereto is in an abnormal state. Also, a signal may be output to a fire receiver (disaster prevention receiver) to which the light control device is connected.

  Conventionally, an administrator who knows the occurrence of an abnormality in a light alarm device using a fire receiver or a light control device identifies the abnormal light alarm device, but multiple light alarm devices are connected to one light control device. In such a case, since the light control device does not know which light alarm device is abnormal, it may be difficult to specify the light alarm device. Also, conventionally, even if each optical alarm has a unique address, and it is output to the light control device to identify the optical alarm in which an abnormality has occurred, it is difficult to confirm the address of the installed optical alarm, Again, it may be difficult to determine which optical alarm is the optical alarm. On the other hand, in the present application, when specifying the optical alarm device in which the abnormality has occurred, the indicator lamp of the optical alarm device in the abnormal state performs the display operation, thereby easily specifying the optical alarm device in which the abnormality has occurred. It becomes.

The supply of the electric signal may be automatically terminated after (for example, 30 seconds to 1 minute). In this case, the control unit of the light control device 2 may be configured to output an electric signal using its own timer until a predetermined time recorded in its own recording unit is reached. Good. In such a configuration, the light control device 2 supplies power to the optical alarm device 1 only for a predetermined time, so that power can be supplied only when necessary, for example, so that power is wasted. Can be prevented. Further, for example, since the power supply can be automatically stopped, the operation of stopping the power supply can be omitted. The power supply by the light control device 2 may be started or terminated by a manual operation by the user.

(About features)
Further, the features of the embodiment and the features of the modified examples may be arbitrarily combined. For example, by adding the diode 33 and the switch 32 of FIG. 5 to the optical alarm 1 of FIG. 2 to change the power consumption and opening and closing the terminals, an abnormal state is detected. You may comprise so that it may output.
