"Management mode" is a mode for managing the light alarm, more specifically, a mode for managing the power storage means, for example, a mode set during maintenance. This is a mode in which an operation test for charging the storage means or a deterioration prevention mode for charging the storage means is performed. "Non-management mode" is a mode different from the management mode, specifically, a mode that does not manage the light alarm, for example, a mode that is set at normal times other than during maintenance. , a mode in which the light emitting means is caused to emit light.

Further, the "first signal form" is a signal form for setting the light alarm to the non-management mode, for example, a signal form that defines the timing at which the light emitting means emits light. It is a signal form that defines the timing of each light emission of the light emitting means that emits light. Further, the "second signal form" is a signal form for setting the light alarm to the management mode. For example, it is a signal form different from the first signal form. It is a signal form to be performed. In addition, the "test operation" refers to the operation test itself for testing the operation of an arbitrary element of the light alarm (for example, electricity storage means), or preparation for the operation test (waiting for the operation test, etc.) It is a concept that includes Further, the "third signal form" is a signal form for setting the light alarm to the non-management mode. is a signal format that does not specify the timing of emitting light, and more specifically, a signal format that does not specify the timing of each light emission of the light emitting means that repeatedly emits light. It is a signal form different from the signal form of . It should be noted that, for each signal form here, one type may be defined for each, or a plurality of types may be defined for each. In particular, the "third signal form" may be interpreted as any signal form other than the first and second signal forms. When a modified signal form is obtained, the modified signal form may be the third signal form.

Further, the "third management process" is, for example, a process of electrically connecting the storage means and the discharge means to each other when performing an operation test of the storage means when the management mode is set. . Note that the "discharging means" is a means for discharging the power stored in the storage means when performing an operation test of the storage means, and is a concept including, for example, electrical resistance for discharging.

Further, the "fourth management process" is, for example, when the power receiving means receives an electric signal for setting the management mode, and when the electric signal is a signal for performing an operation test of the power storage means, the power storage means It is a concept that includes means for conducting operation tests of The "electrical signal to be set in the management mode" is, for example, an electric signal in the "second signal form" or a dedicated terminal for receiving an electric signal for conducting an operation test of the storage means. In this case, it is a concept corresponding to an electric signal received by the dedicated terminal (that is, power (electrical signal) received by the first terminal among the plurality of terminals described above) and the like.

In the following embodiments, a case where the "storage means" is a capacitor and the "management means" performs the first management process, the third management process, and the fourth management process will be exemplified. , and the case where the "management means" performs the second management process will be described in a modified example.

[Specific contents of the embodiment]
Next, specific contents of the embodiment will be described.

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

The optical alarm system 900 of FIG. 1 is a disaster prevention system, and includes, for example, a plurality of optical alarms 1 and an optical control device 2 . Although the number of light alarm devices 1 connected to the light control device 2 is arbitrary, here, for example, three light alarm devices 1 are illustrated. Also, since the configuration of each of the plurality of light alarm devices 1 is the same, one light alarm device 1 will be described as a representative. Further, FIG. 1 illustrates a case where the light control device 2 is connected to the light alarm 1, and the light control device 2 is controlled by the light alarm 1 based on the control from the disaster prevention receiver (not shown). will be described by exemplifying a case where various signals are transmitted to and controlled. In addition, unless otherwise specified, the light control device 2 can have the same configuration as the conventional one, so detailed description of the light control device 2 itself will be omitted.

(Configuration - light alarm)
FIG. 2 is a circuit diagram of the light alarm. The light alarm device 1 is a device that emits light to give an alarm. A second switch 16 , a first diode 17 , a second diode 18 , a third switch 191 and a discharge resistor 192 are provided.

(Configuration - light alarm - terminal)
The management terminal T1 is the above-described power receiving means, and is a first terminal. Specifically, power is supplied by an electric signal. is a terminal to which an electrical signal is input to, and for example, a terminal electrically connected to the light control device 2 side. The power supply terminal T2 is the power receiving means described above and is a second terminal. Specifically, power is supplied by an electric signal. It is a terminal to which an electric signal is input when the light control device 2 is to be switched on, and for example, a terminal electrically connected to the light control device 2 side. 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, for example, as the above-described management means or power supply terminal confirmation 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 for emitting light, and is specifically an LED, which emits light by the power of the capacitor 12, for example. The 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 . The state in which the second switch 16 is open corresponds to electrically disconnecting the capacitor 12 and the light emitting diode 13 from each other, and the state in which the second switch 16 is closed corresponds to the state in which the capacitor 12 and the light emitting diode 13 are electrically disconnected. This corresponds to electrically connecting the light emitting diodes 13 to each other. 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 . The third switch 191 is switching means for switching the connection destination of one end of the capacitor 12. For example, the one end is electrically connected to the first contact 193 on the first diode 17 side, or the one end is used for discharging. It is electrically connected to the second contact 194 on the resistor 192 side. The discharge resistor 192 is the discharge means described above, and is, for example, an electrical resistor. With such a configuration, the discharge test of the capacitor 12 can be performed while maintaining the power supply to the control unit 11 from the outside and keeping the voltage supplied to the control unit 11 unchanged.

(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. Further, when the control process is started, the first switch 15 and the second switch 16 are in an open state as shown in the drawing, and the third switch 191 is in the open state of the capacitor 12 as shown in the drawing. Assume that one end is connected to the first contact 193 .

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, in the same manner as in the conventional art, when the light alarm device 1 is operated in the non-management mode at the time of fire or the like, the light control device 2 connects the power supply terminal T2 to the power supply terminal T2 shown in FIG. providing the electrical signal of b); 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 during maintenance, the light control device 2 supplies the electrical signal shown in 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, an operation test regarding charging of the capacitor 12 is performed with the second switch 16 opened so that the light emitting diode 13 does not emit light, for example. Specifically, the capacitor 12 is charged by the electrical signal shown in FIG. or by detecting the maximum voltage generated in the capacitor 12 to specify the maximum charging capacity of the capacitor 12, and any method (for example, A method of judging that the specified value is normal if both of the specified values are within a predetermined reference range, and that it is abnormal if at least one of the specified values is outside the reference range. etc.) to determine whether it is normal or not. Here, for example, it is assumed that the capacitor 12 may be repeatedly tested for operation 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 the discharge, the control unit 11 switches the third switch 19 to connect one end of the capacitor 12 to the second contact 194 to discharge or discharge the capacitor 12 . is connected to the first contact 193 for charging. Also, by monitoring the voltage on the first contact side of the capacitor 12, it becomes possible to determine the discharge speed when connected to the discharge resistor 192 with a known resistance value, and estimate the capacity of the capacitor from the discharge speed. It becomes possible to detect the capacity abnormality of the capacitor.

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. Specifically, when it is determined to be normal in SA2, the capacitor 12 is normal by keeping the first switch 15 in FIG. Output that it was determined to be a thing. If SA2 determines that the capacitor 12 is not normal, the first switch 15 in FIG. Output. In this configuration, by monitoring the power consumption of the light alarm device 1 on the side of the light control device 2 shown in FIG. It is possible to comprehend.

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, current also flows to the resistor 14 side, which corresponds to a relatively large change. It is a concept. Then, 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 whether the charging of the capacitor 12 is normal as a result of management. It is possible to grasp whether or not

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, when the management mode is set, the capacitor 12 and the light emitting diode 13 are electrically disconnected (disconnected) from each other, thereby preventing light emission. When the non-management mode is set, the capacitor 12 and the light emitting diode 13 are electrically connected (connected state) to each other, and are controlled to emit light. Therefore, for example, it is possible to manage without emitting light. That is, for example, since the light alarm can be managed without misleading the user, the degree of freedom in the timing of management increases, making it possible to provide an easy-to-manage light alarm. In particular, by electrically connecting or disconnecting the capacitor 12 and the light emitting diode 13, light emission control and non-light emission control are performed. A voltage can be applied to the storage means without delay, and deterioration of the capacitor 12 can be prevented.

Further, when it is confirmed that power is supplied from the management terminal T1, the management mode is set, and when it is confirmed that the power is supplied from the power supply terminal T2, the non-management mode is set. Since signal interference can be prevented, it is possible to appropriately set the managed mode or the non-managed mode.

Further, by providing the discharge resistor 192 to the power receiving means and the signal receiving means, for example, the capacitor 12 can be charged and discharged, and the operation test of the capacitor 12 can be performed.

[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 electrical signal is input to the management terminal T1, the light alarm 1 is set to the non-management mode, and when an electrical signal is input to the power supply terminal T2, the light alarm 1 is set to the management mode. can be set to

(Regarding charging management)
Further, in the above embodiment, the case where the operation test regarding charging of the capacitor 12 is performed at SA2 in FIG. Specifically, the deterioration prevention is arbitrary, but for example, the capacitor 12 may be charged or discharged one or more times by operating the third switch 191 described in SA2. In this case, the processing of SA3 may be omitted, or the fact that the processing of SA2 has ended may be output at SA3 due to the change in the power consumption of the light alarm device 1 . When configured in this way, by preventing deterioration related to charging of the capacitor 12, for example, when an alarm is issued, the light alarm device 1 can be managed so as to operate normally, thereby improving disaster prevention. becomes possible. This deterioration prevention may be performed together with the operation test.

(About information output)
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 control device 2 acquires information, a negative voltage is applied to the power supply terminal T2, and a current flows from the ground terminal T3 side to the power supply terminal T2 via the diode 33 and the switch 32. The information may be acquired by determining whether or not the information is supplied. Further, for example, a speaker is provided in the light alarm device 3 to output information by voice from the speaker, or a wireless or wired communication function is provided and information is output using the communication function. good too.

(Regarding the second management process (part 1))
Also, the control unit 11 of the above embodiment may be configured to execute the second management process. 6A and 6B are diagrams illustrating electrical signals output by the light control device, where (a) illustrates the electrical signal in the first signal form, and (b) and (c) illustrate the second signal form. FIG. 11 illustrates an electrical signal in a signal form, and (d) illustrates an electrical signal in a third signal form. Note that FIG. 6(b) exemplifies an electrical signal in a signal form that only sets the management mode and does not perform an operation test regarding charging of the capacitor 12, and FIG. 6(c). illustrates an electrical signal in the form of a signal to set the management mode and to perform an operational test on the charging of the capacitor 12. FIG. Then, the light control device 2 of FIG. 1 appropriately inputs the electric signals of (a) to (d) of FIG. 6 to the management terminal T1 (that is, one power receiving means) of FIG. do.

Then, after the control unit 11 in FIG. 2 is configured to function as the above-described management means and electrical signal confirmation means, the control unit 11 can use any method (characteristics of the signal form (e.g., amplitude, period, pulse Width, etc.), the signal form of the electrical signal input via the management terminal T1 is confirmed, the operation mode is set based on the confirmed signal form, and the set operation mode is selected. It may be configured to perform corresponding control.

For example, when confirming the first signal form or the third signal form as the signal form of the electrical signal input via the management terminal T1, after setting the non-management mode, SA4 in FIG. A similar control is performed to cause the light emitting diode 13 to emit light. In particular, when confirming the first signal form shown in FIG. 6(a), the second switch 16 is momentarily closed at the pulse timing in the same manner as the electrical signal shown in FIG. 4(a) to emit light. Flash light is output from the diode 13 . That is, in this case, the light emitting diode 13 is caused to emit light according to the signal form of the electrical signal shown in FIG. 4(a). Further, when the third signal form shown in FIG. 6(d) is confirmed, the light emitting diode 13 is detected at predetermined time intervals using its own timer in the same manner as the electric signal shown in FIG. 4(b). to output flash light.

Further, for example, when the second signal form is confirmed as the signal form of the electric signal input via the management terminal T1, the light emitting diode 13 is not caused to emit light after setting the management mode. In particular, when the second signal form shown in FIG. 6(b) is confirmed, the processing described in SA2 of FIG. 3 is not performed. Also, when the second signal form shown in (c) of FIG. 6 is confirmed, the same processing as SA2 and SA3 in FIG. 3 is performed. In this configuration, when the electrical signal is in the first signal form, the non-management mode is set, the light emitting diode 13 is caused to emit light according to the electrical signal, and when the electrical signal is in the second signal form, When the management mode is set and the electrical signal is in the third signal form, the non-management mode is set and the light-emitting diode 13 is caused to emit light at a predetermined timing. Since more than one of the three signal forms can be input and controlled, the number of terminals used to operate the light alarm 1 can be reduced. Further, for example, in order to set the management mode, by using an electrical signal in the second signal format, which is different from the first signal format and the third signal format, the voltage is applied to the capacitor 12 in a state in which no light is emitted. can be applied, and deterioration of the capacitor 12 can be prevented.

(Regarding the second management process (part 2))
In addition, although the case of inputting an electric signal to the management terminal T1 was illustrated in "Regarding the second management process (part 1)", the second management process is executed by inputting an electric signal to the power supply terminal T2. Alternatively, an electrical signal may be input to the management terminal T1 and the power supply terminal T2 to execute the second management process.

(Regarding the second management process (Part 3))
As a method for the control unit 11 to confirm the signal form of the electric signal input via the management terminal T1, for example, the following method may be used. For example, a first determination criterion (for example, a criterion related to amplitude, period, pulse width, etc.) that is a reference condition for determining that the signal is in the first signal form, and a criterion for determining whether or not it is in the second signal form It is assumed that the second criterion (for example, criteria related to amplitude, period, pulse width, etc.) which is a condition is recorded in the memory of the control unit 11, and this criterion is acquired and input via the management terminal T1. If the electrical signal meets the first criterion, it is determined (confirmed) that it is in the first signal format. If it is determined (confirmed) that it is in the second signal format, and on the other hand, if the electrical signal input via the management terminal T1 does not satisfy both the first determination criterion and the second determination criterion, the third signal format is determined. You can judge (confirm) that it is. When configured in this way, the main function of the light alarm 1 is to emit light. Even if the signal is disturbed during transmission, it is possible to perform the optical alarm, which is the main function.

If the signal is for testing, an operation test of the storage means is performed.

(Effect of Supplementary Note)
According to the light alarm device described in appendix 1, when the management mode is set, the power storage means and the light emitting means are electrically disconnected from each other to control so as not to emit light, and the non-management mode is set. When the mode is set, the storage means and the light emitting means are electrically connected to each other, and by performing control so as to emit light, for example, it is possible to manage without emitting light. That is, for example, since the light alarm can be managed without misleading the user, the degree of freedom in the timing of management increases, making it possible to provide an easy-to-manage light alarm. In particular, by electrically connecting or disconnecting the electricity storage means and the light emitting means, light emission control and non-light emission control are performed. A voltage can be applied to the storage means, and deterioration of the storage means can be prevented.

According to the light alarm device described in Supplementary Note 2, when it is confirmed that power is supplied from the first terminal, it is set to the management mode, and when it is confirmed that power is supplied from the second terminal, non-management By setting the mode, for example, it is possible to prevent signal interference at the terminal, so it is possible to appropriately set the management mode or the non-management mode.

According to the light alarm device described in Supplementary Note 3, when the electrical signal is in the first signal form, the non-management mode is set, the light emitting means is caused to emit light according to the electrical signal, and the electrical signal is in the second signal form , the management mode is set, and when the electrical signal is in the third signal form, the non-management mode is set and the light emitting means is caused to emit light at a predetermined timing, for example, for one terminal Since a plurality of the first to third signal forms can be input and controlled, it is possible to reduce the number of terminals used to operate the light alarm. Further, for example, in order to set the management mode, by using an electric signal in the second signal form, which is different from the first signal form and the third signal form, voltage is applied to the storage means in a state in which light is not emitted. can be applied, and deterioration of the storage means can be prevented. In addition, the main function of the light alarm is to emit light. If none of the control signal forms apply, it can be regarded as the third signal form, and even if the signal form is disturbed during transmission, it is possible to perform the main function of light alarm. becomes.
