Further, the ground terminal T3 is, for example, a terminal on the ground side, and as an example, is a terminal electrically connected to the light control device 2 side.

(Configuration - light alarm - control unit)
The control unit 11 is control means for controlling the light alarm device 1, and specifically includes a CPU, various programs interpreted and executed on the CPU (a basic control program such as an OS, and a specified program started on the OS). (including application programs that implement functions), and an internal memory such as a RAM for storing programs and various data. In particular, the program according to the embodiment substantially configures each section of the control section 11 by being installed in the light alarm device 1 via any recording medium or network.

Functionally, the control unit 11 functions as, for example, output means and determination means. Specific processing performed by each section of the control section 11 will be described later.

(Configuration - light alarm - each element)
The capacitor 12 is an electric storage unit that is charged with electric power, and is charged with electric power for causing the light emitting diode 13 to emit light, for example. The light-emitting diode 13 is light-emitting means that emits light, and is specifically an LED (Light Emitting Diode), which emits light by the power of the capacitor 12, for example. A resistor 14 is a changing means for changing the power consumption of the light alarm device 1, and is an electrical resistor, for example. The first switch 15 is a first opening/closing unit whose opening/closing is controlled by the control unit 11, and is an opening/closing switch that electrically opens/closes between the management terminal T1 and the resistor 14, for example. The second switch 16 is a second opening/closing unit whose opening/closing is controlled by the control unit 11 , and is, for example, an opening/closing switch that electrically opens/closes between the capacitor 12 and the light emitting diode 13 .

A 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. It can be configured by including a part and the like.

(process)
Next, control processing executed by the light warning system 900 configured in this manner will be described. FIG. 3 is a flow chart of control processing (steps are abbreviated as “S” in the following description of each processing), and FIG. 4 is a diagram illustrating electrical signals output by the light control device, (a) shows an electrical signal containing pulses, and (b) shows an electrical signal without pulses. The “control process” is roughly a process executed by the light alarm device 1 of the light alarm system 900 , and specifically a process of controlling the light alarm device 1 . Although the timing of executing this control process is arbitrary, for example, when an electric signal is received 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 process is started. It is assumed that the execution is started by pressing the

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. In the following description, it is assumed that when an electric signal is supplied to T2, it is configured to operate based on the power of the electric signal. Note that FIG. 2 does not show known electric circuits including the regulator circuit and the like for convenience of explanation. Further, for example, in each terminal of the light alarm 1 in FIG. 2, the ground terminal T3 is grounded through 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. A case will be described as an example. Also, it is assumed that the first switch 15 and the second switch 16 are in an open state as shown in the drawing when the control process is started.

At SA1 in FIG. 3, the control unit 11 determines whether or not to set the management mode as its own operation mode. Specifically, it is optional, but for example, as indicated by thin arrows in FIG. (the voltage on the anode side of the second diode 18) can be monitored, and based on the monitoring result, it is determined to which terminal the electrical signal is input, and based on the determination result, It determines whether or not to set the management mode as its own operation mode. When the light control device 2 supplies an electrical signal to the power supply terminal T2, it determines that the electrical signal has been input to the power supply terminal T2, and determines that the management mode is not set as its own operation mode ( NO in SA1), set the non-management mode, and proceed to SA4. When the light control device 2 supplies an electrical signal to the management terminal T1, it determines that the electrical signal has been input to the management terminal T1, and determines that the management mode is set as its own operation mode (SA1). YES), after setting the management mode, shift to SA2.

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

At SA2 in FIG. 3, the control unit 11 manages charging of the capacitor 12. FIG. Specifically, although it is optional, for example, the 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 to determine the state of the light alarm device 1. For example, regarding the charging speed or maximum charge capacity of the capacitor 12, the light alarm device 1 is in a normal state or an abnormal state (predetermined state). Specifically, the capacitor 12 is charged by the electric signal shown in FIG. 4B supplied to the management terminal T1, and the 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 developed across capacitor 12 may be detected to identify the maximum charge capacity of capacitor 12, and any method (e.g., A method of determining that the state is normal when both are within a predetermined reference range, and determining that the state is abnormal when at least one of the specified values is outside the reference range. etc.), an operation test is performed by determining whether the state is normal or abnormal. Here, for example, it is assumed that the capacitor 12 may be repeatedly subjected to an operation test a plurality of times for determination. In this case, the capacitor 12 needs to be charged and discharged repeatedly. In order to repeatedly charge and discharge the capacitor without causing a voltage drop, 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 is provided. may be provided to charge the capacitor 12 with the third switch open and to discharge the capacitor 12 with the third switch closed. In this case, when the third switch is closed, a known method (providing an electrical resistance at an arbitrary location, etc.) is used so that the management terminal T1 and the ground terminal T3 are not short-circuited by the light alarm device 1. may It should be noted that control of opening and closing of the third switch here is also executed by the control unit 11 .

At SA3 in FIG. 3, the control unit 11 outputs the result of the management performed at SA2, and then terminates the process. Specifically, it is arbitrary, but for example, the result of the operation test of SA2 is detected in the state where the second switch 16 is opened so that the light emitting diode 13 does not emit light. It outputs according to the change in the power consumption of the device 1. More specifically, when it is determined in SA2 that the state is normal, the light alarm for the capacitor 12 is suppressed by maintaining the open state of the first switch 15 in FIG. It outputs that the device 1 has been determined to be in a normal state (that is, it has not been determined to be in an abnormal state). If SA2 determines that the light alarm 1 is in an abnormal state, the first switch 15 in FIG. Output that it is determined to be In this configuration, by monitoring the power consumption of the light alarm 1 on the side of the light control device 2 shown in FIG. It is possible to grasp whether it has been determined or determined to be in an abnormal state.

Regarding the expressions "does not change the power consumption" and "changes the power consumption", in fact, the power consumption of the light alarm 1 depends on the operating conditions of the CPU of the control unit 11. It is a concept that either changes slightly or does not take into account this slight change. Specifically, "does not change the power consumption" is a concept corresponding to, for example, not changing the power consumption as much as when closing the first switch 15 so that the current also flows to the resistor 14 side. In addition, "to change the power consumption" is a concept based on the same point of view. For example, by closing the first switch 15, the current also flows to the resistor 14 side, which corresponds to a relatively large change. It is a concept. On the side of the light control device 2 in FIG. 1, by comparing the power consumption of the light alarm device 1 with a predetermined threshold value, it is determined that the light alarm device 1 is in a normal state as a result of management relating to charging of the capacitor 12. It is possible to grasp whether it is determined that there is an abnormal state or that it is determined to be in an abnormal state.

On the other hand, in SA1 of FIG. 3, it is determined that the management mode is not set as the self 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 optional, and a conventional method is used to emit light to give an alarm, and only the outline will be described here. For example, when an electrical signal containing a light emission synchronization signal (a signal for synchronizing the light alarm 1 from the outside), which is a pulse in FIG. Flash light is output from the light emitting diode 13 by momentarily closing the second switch 16 and instantaneously supplying current from the capacitor 12 side to the light emitting diode 13 . Further, when an electrical signal that does not include the light emission synchronization signal, which is the pulse of FIG. The second switch 16 is momentarily closed at predetermined time intervals using its own timer, and current is momentarily supplied to the light emitting diode 13 from the capacitor 12 side. A flash light is output from the light emitting diode 13 by supplying the light directly. When the transmission of the electrical signal from the light control device 2 ends, the output of the flash light ends. This completes the control process.

(Effect of Embodiment)
As described above, according to the present embodiment, by changing the electrical state of the light alarm device 1 and outputting that an abnormal state has occurred, which is a predetermined state, for example, an abnormal state has occurred. can be output. Further, for example, it is possible to output that an abnormal state has occurred without causing the light alarm device 1 to emit light, so it is possible to prevent users in the vicinity from being annoyed.

In addition, by outputting an abnormal state by changing the power consumption of the light alarm device 1, for example, by grasping the power consumption of the light alarm device 1, the light alarm device 1 becomes an abnormal state. Therefore, it is possible to easily grasp that an abnormal state has occurred.

Further, 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]
Although the embodiments according to the present invention have been described above, the specific configuration and means of the present invention can be arbitrarily modified and improved within the scope of the technical ideas of each invention described in the claims. can be done. Such modifications will be described below.

(Problem to be solved and effect of 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 details of the implementation environment and configuration of the invention. or only part of the effects described above.

(Regarding decentralization and integration)
Moreover, the configuration described above is functionally conceptual, and does not necessarily have to be physically configured as illustrated. That is, the specific form of distribution or integration of each part is not limited to the illustrated one, and all or part of them can be functionally or physically distributed or integrated in arbitrary units. In addition, the term "device" in the present application is not limited to one configured by a single device, but includes one configured by a plurality of devices.

(Regarding management mode settings)
Further, in the above embodiment, in SA1 of FIG. 3, when an electrical signal is input to the management terminal T1, the light alarm 1 is set to the management mode, and an electrical signal is input to the power supply terminal T2. Although the light alarm device 1 is set to the non-management mode in such a case, it may be changed arbitrarily.

For example, when an electric signal is input to the power supply terminal T2 and the electric signal includes a command to set the management mode, the light alarm 1 is set to the management mode, while the power supply terminal T2 is set to the management mode. and the electrical signal does not include a command to set the management mode, the non-management mode may be set. In this case, since the management terminal T1 becomes unnecessary, the management terminal T1 may be omitted.

Further, for example, the electric signal shown in FIG. 4B is input to the power supply terminal T2, and an arbitrary signal (eg, positive single pulse, burst signal, etc.) is input to the management terminal T1 to set the management mode. is input as a management mode setting signal, the light alarm 1 is set to the management mode, while the electrical signal of FIG. 4B is input to the power supply terminal T2, and the management terminal T1 The optical alarm device 1 may be set to the non-management mode when the mode setting signal is not input.

(Regarding charging management (Part 1))
Further, in the above-described embodiment, in SA2 of FIG. 3, the case where the operation test regarding charging of the capacitor 12 is performed has been described. Other determinations may be made to determine whether or not the state is in an abnormal state. For example, the control unit 11 is provided with a function to detect an unintended short circuit, disconnection, or the like at any point in the electric circuit of the light alarm 1, and an abnormal state occurs when the short circuit, disconnection, or the like is detected. If the short circuit or disconnection is not detected, it may be determined that the state is normal. Further, for example, the process of determining whether other arbitrary elements of the light alarm device 1 are in a normal state or an abnormal state may be similarly performed.

(Regarding charging management (Part 2))
In the above-described embodiment, SA2 in FIG. 3 exemplifies the case where the operation test is performed without emitting light. However, the present invention is not limited to this. A performance test may be performed.

(Information output (part 1))
Further, in the above embodiment, the case where the power consumption of the light alarm device 1 is increased to output that the light alarm device 1 is in an abnormal state has been described in SA3 of FIG. Alternatively, by reducing the power consumption of the optical alarm device 1, it is possible to output that the optical alarm device 1 is in an abnormal state. In this case, specifically, the power consumption of the light alarm device 1 may be reduced by keeping the first switch 15 closed at all times and opening the first switch 15 when an abnormal state is determined. .

(Information output (part 2))
In the above-described embodiment, by varying the amount of power consumption to be changed in the plurality of light alarms 1 of FIG. 1, the light alarm 1 determined to be in an abnormal state can be uniquely identified. You may In this case, it may be realized by making the resistance value of the resistor 14 different in each optical alarm device 1 . Further, in one light alarm 1, a plurality of resistors such as the resistor 14 are provided, and the resistance values of the plurality of resistors are made different from each other. is provided, and the control unit 11 controls the switching circuit to switch the resistor electrically connected to the management terminal T1 among the plurality of resistors, thereby changing the power consumption of the light alarm 1 in multiple stages. , corresponding to a number of mutually different predetermined states (for example, normal state and abnormal state, or a first abnormal state corresponding to capacity loss of a capacitor, a second abnormal state corresponding to a short circuit, and a disconnection of a circuit). It may be configured to output a third abnormal state, etc.).

(Information output (Part 3))
Further, in the above embodiment, SA3 in FIG. 3 describes a case where information is output according to a change in power consumption of the light alarm device 1, which is the electrical state of the light alarm device 1. However, the present invention is not limited to this. . FIG. 5 is a circuit diagram of another optical alarm. The optical alarm 3 of FIG. 5 is obtained by omitting the first switch 15 and the resistor 14 from the optical alarm 1 of FIG. 2 and adding a switch 32 and a diode 33 . Then, as in the light alarm device 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 controller 31 opens and closes the switch 32. , the power supply terminal T2 and the ground terminal T3 may be electrically opened and closed to output information. Specifically, when the light alarm 1 is determined to be in a normal state, the switch 32 is opened, and when the light alarm 1 is determined to be in an abnormal state, the switch 32 is opened. may be output with the closed. In this case, when the light control device 2 acquires information, a negative voltage is applied to the power supply terminal T2, and a current is supplied from the ground terminal T3 side to the power supply terminal T2 via the diode 33 and the switch 32. Information specifying whether the light alarm device 1 is in a normal state or an abnormal state may be obtained by determining whether or not the light alarm device 1 is in a normal state or an abnormal state. In the case of such a configuration, by electrically opening and closing between a plurality of terminals of the light alarm device 3, by outputting that an abnormal state, which is a predetermined state, has occurred, the terminals of the light alarm device 3 are output, for example. By applying a voltage to , it is possible to grasp that a predetermined state has been reached. Therefore, it is possible to easily grasp that a predetermined state has been reached.

(About indicator light)
Also, the light alarm may be provided with an indicator lamp for indicating an abnormal state. The indicator lamp 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 be provided with an indicator light, and may light up the indicator light when receiving a signal outputting that any of the light alarm devices connected thereto is in an abnormal state. Alternatively, the signal may be output to a fire receiver (disaster prevention receiver) to which the light control device is connected.

Conventionally, when a fire receiver or light control device detects an abnormality in a light alarm, an administrator identifies the light alarm in which the abnormality has occurred, but multiple light alarms are connected to one light control device. Since the light control device does not know which light alarm is abnormal when the light alarm is detected, it may be difficult to identify the light alarm. In addition, conventionally, even if each light alarm has a unique address and an output to the light control device identifies the light alarm in which an abnormality has occurred, it is difficult to confirm the address of the installed light alarm. After all, there was a possibility that it would be difficult to grasp which light alarm device is the light alarm device. On the other hand, in the present application, when identifying the light alarm in which an abnormality has occurred, the indicator lamp of the light alarm in an abnormal state performs a display operation, so that it is easy to identify the light alarm in which an abnormality has occurred. becomes.

(About the light control device)
Further, as described in the above embodiment, when the light control device 2 starts supplying the electric signal (power) shown in FIG. 4B to the management terminal T1 shown in FIG. It may be configured such that the supply of the electric signal is automatically terminated after (for example, 30 seconds to 1 minute). In this case, the control unit of the light control device 2 may use its own timer to output an electric signal until the predetermined time recorded in its own recording unit is reached. good. With this configuration, the light control device 2 supplies power to the light alarm device 1 only for a predetermined period of time, for example, so that power can be supplied only when necessary, so power is wasted. It is possible to prevent Further, for example, since the power supply can be automatically stopped, it is possible to omit the operation of stopping the power supply. It should be noted that the light control device 2 may be configured to start or end the power supply by manual operation by the user.

(About features)
Moreover, the features of the embodiment and the features of the modifications may be combined arbitrarily. For example, by adding the diode 33 and the switch 32 in FIG. 5 to the light alarm device 1 in FIG. It may be configured to output
