[Diagram 2] 1 is a diagram illustrating a configuration of a disaster prevention wireless receiving adapter according to a first embodiment. [Diagram 3] FIG. 11 is a diagram for explaining the configuration of a microcomputer writing adapter according to a second embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] The following description will be made with reference to the drawings regarding the disaster prevention light lighting device, the disaster prevention light, and the disaster prevention light system according to each embodiment. The same or corresponding components are designated by the same reference numerals, and the description may be omitted.

[0010] Embodiment 1 FIG. 1 is a diagram illustrating the configuration of a disaster prevention light 100 according to the first embodiment. The disaster prevention light 100 of this embodiment is a flashing emergency light with emergency sound. However, the disaster prevention light 100 is not limited to this and may be another type of disaster prevention light. The disaster prevention light 100 includes a disaster prevention light lighting device 50 and a light source 7. The light source 7 is, for example, a light-emitting element such as an LED.

[0011] Disaster prevention light lighting device 50 rectifies AC power supplied from commercial power source 1 using diode bridge 2, and insulates and reduces the voltage using flyback circuit 3. This reduced-voltage power is supplied to charging circuit 4, which charges rechargeable battery 5. Power is supplied from rechargeable battery 5 to power supply circuit 8, which supplies power to each circuit such as microcomputer 9. Microcomputer 9 is also called a microcomputer. Microcomputer 9 controls flyback circuit 3, charging circuit 4, flashing circuit 6, power supply circuit 8, and audio LSI 10.

[0012] The microcomputer 9 charges the rechargeable battery 5 during normal use, and in an emergency, receives power from the rechargeable battery 5 and drives the light source 7 to blink using the blinking circuit 6. The blinking circuit 6 corresponds to a lighting circuit that lights the light source 7 using the power from the rechargeable battery 5.

[0013] Furthermore, in an emergency, the microcomputer 9 activates an audio LSI (Large Scale Integration circuit) 10 and emits a guiding sound from a speaker 13a via an audio amplifier 12a. The audio amplifier 12a is connected to the audio LSI 10 or a write terminal 14f of a communication connector 14 (described later) by a switch 11. When the audio amplifier 12a is connected to the audio LSI 10, the guiding sound is output from the speaker 13a.

[0014] The communication connector 14 is a connector for the microcomputer 9 to communicate with an external device. The communication connector 14 is provided so as to be connectable to an external device. The communication connector 14 has a power terminal 14a, a ground terminal 14b, a transmission terminal 14c, a reception terminal 14d, a reset terminal 14e, and a write terminal 14f. The transmission terminal 14c and the reception terminal 14d are terminals for performing communication, for example, by serial communication. The reset terminal 14e is a terminal for resetting the microcomputer 9. The write terminal 14f is a terminal for writing a program or the like to the microcomputer 9.

[0015] The communication connector 14 is, for example, a connector provided on the same board as the microcomputer 9. By connecting various adapters, which are external devices, to the communication connector 14, it is possible to add functions to the disaster prevention light 100.

[0016] For example, by connecting an external device to the communication connector 14, writing can be performed to the microcomputer 9 through the write terminal 14f. In addition to writing to the microcomputer 9 through the write terminal 14f, the disaster prevention light lighting device 50 may be capable of transmitting or receiving data through the write terminal 14f. In other words, the write terminal 14f can be used as a terminal for data transfer except when writing to the microcomputer. The disaster prevention light lighting device 50 may be capable of outputting data received through the write terminal 14f to the outside. Data is output to the outside by, for example, the speaker 13a.

[0017] Fig. 2 is a diagram for explaining the configuration of the disaster prevention wireless receiving adapter 101 according to the first embodiment. An example will be explained with reference to Fig. 2 in which the external device connected to the communication connector 14 is the disaster prevention wireless receiving adapter 101. The disaster prevention light 100 and the external device are collectively referred to as a disaster prevention light system.

[0018] The disaster prevention wireless receiving adapter 101 includes a communication connector 15, a microcomputer 16, an antenna 17, a disaster prevention wireless receiving circuit 18, and a switch 19. The communication connector 15 is connected to the communication connector 14.

[0019] The communication connector 15 has a power terminal 15a, a ground terminal 15b, a transmission terminal 15c, a reception terminal 15d, a reset terminal 15e, and a write terminal 15f. When the communication connector 15 and the communication connector 14 are connected, the power terminal 15a is connected to the power terminal 14a, the ground terminal 15b is connected to the ground terminal 14b, the reset terminal 15e is connected to the reset terminal 14e, and the write terminal 15f is connected to the write terminal 14f. The transmission terminal 15c is connected to the reception terminal 14d, and the reception terminal 15d is connected to the transmission terminal 14c.

[0020] The microcomputer 16 operates by receiving power from the power circuit 8 of the disaster prevention light lighting device 50 via the power terminals 14a, 15a of the communication connectors 14, 15. A write terminal 15f of the communication connector 15 is connected to the microcomputer 16 or a disaster prevention radio receiving circuit 18 via a switch 19. The antenna 17 receives the disaster prevention radio signal. The disaster prevention radio signal is also called a municipal disaster prevention administrative radio signal.

[0021] When the disaster prevention radio receiving circuit 18 receives a disaster prevention radio signal via the antenna 17, the microcomputer 16 notifies the microcomputer 9 of the disaster prevention light 100 that the disaster prevention radio signal has been received, via communication via the transmission terminal 15c and the reception terminal 14d.

[0022] When disaster prevention radio broadcasting is possible, the microcomputer 9 of the disaster prevention light 100 notifies the microcomputer 16 of the disaster prevention radio receiving adapter 101 via the transmission terminal 14c that broadcasting is possible, and switches the switch 11 to the write terminal 14f side.

[0023] The microcomputer 16 of the disaster prevention radio receiving adapter 101, which has been notified that broadcasting is possible, switches the switch 19 to the output side of the disaster prevention radio receiving circuit 18. As a result, with the disaster prevention radio receiving circuit 18 and the write terminal 15f connected, the disaster prevention radio is transmitted to the disaster prevention light lighting device 50 via the write terminals 15f and 14f.

[0024] When the disaster prevention light lighting device 50 receives a disaster prevention radio signal from the disaster prevention radio receiving adapter 101 via the communication connector 14, the device outputs the received disaster prevention radio signal from the speaker 13a. The disaster prevention radio signal is broadcast from the speaker 13a via the write terminal 14f and the audio amplifier 12a.

[0025] In this way, when the microcomputer 9 is notified that a disaster prevention radio signal has been received from the disaster prevention radio receiving adapter 101 via the receiving terminal 14d, it operates the switch 11 to output the disaster prevention radio signal from the speaker 13a. The switch 11 switches the information to be output from the speaker 13a between the guiding sound and the disaster prevention radio signal.

[0026] In the disaster light lighting device 50 and the disaster light 100 according to this embodiment, functions can be added by connecting an external device to the communication connector 14. In this case, since there is no need to replace the disaster light 100 itself, the cost of adding functions can be suppressed. Also, the disaster light 100 can be prevented from becoming larger. Also, in this embodiment, it is sufficient to connect an external device to the communication connector 14 as necessary. Therefore, it is possible to prevent unnecessary costs from being incurred by users who do not need to add functions.

[0027] Furthermore, when incorporating a function for broadcasting disaster prevention radio signals into a disaster prevention light lighting device, it is necessary to set the frequency of the corresponding area for each device. In contrast, in this embodiment, a disaster prevention radio receiving adapter 101 that matches the frequency of the corresponding area can be connected to the disaster prevention light 100 as necessary. Therefore, the disaster prevention light 100 can be added with the function of receiving and broadcasting municipal disaster prevention administrative radio signals at the minimum necessary cost.

[0028] The control of the disaster prevention light 100 and the disaster prevention radio receiving adapter 101 for outputting the disaster prevention radio signal described in this embodiment is an example, and is not limited to the above. The disaster prevention radio receiving adapter 101 only needs to be able to receive the disaster prevention radio signal and transmit it from the communication connector 15. The disaster prevention light lighting device 50 only needs to be able to receive the disaster prevention radio signal from an external device via the communication connector 14 and output it from the speaker 13a.

[0029] Furthermore, the configuration of the disaster prevention light 100 is not limited to that shown in Fig. 1. For example, in the present embodiment, the lighting circuit is described as an example of a flashing circuit 6 that flashes the light source 7 with power from the rechargeable battery 5 in an emergency. However, the lighting circuit is not limited to this and may be any circuit that at least lights the light source 7 with power from the rechargeable battery 5 in an emergency.

[0030] In this embodiment, an example has been described in which the content received by the disaster prevention wireless receiving adapter 101 is output from the speaker 13a, but it is also possible to send an audio signal in the opposite direction from the disaster prevention light 100 using the same path. For example, a microphone amplifier 12b and a microphone 13b may be provided in the disaster prevention light 100, and audio from the microphone amplifier 12b and microphone 13b may be sent to the disaster prevention wireless receiving adapter 101 via the write terminal 14f using a path in the opposite direction to the output from the audio amplifier 12a and speaker 13a. In this way, data may be sent from the disaster prevention light lighting device 50 via the write terminal 14f.

[0031] In the present embodiment, an example has been described in which the disaster prevention radio signal received from the disaster prevention radio receiving adapter 101 is output from the speaker 13a. As a modified example, the disaster prevention radio receiving adapter 101 may receive a voice signal based on the user's speech by wireless communication, and transmit the received voice signal from the communication connector 15 to the disaster prevention light lighting device 50. The disaster prevention light lighting device 50 receives the voice signal via the write terminal 14f and outputs it from the speaker 13a. As described above, the disaster prevention light lighting device 50 may be provided with a microphone 13b, and the disaster prevention radio receiving adapter 101 may further have a transceiver function for transmitting voice from the microphone 13b. This enables two-way conversation between the disaster prevention light 100 and the wireless communication destination of the disaster prevention radio receiving adapter 101.

[0032] The above-mentioned modifications can be appropriately applied to the disaster prevention light lighting device, disaster prevention light, and disaster prevention light system according to the following embodiments. Note that the disaster prevention light lighting device, disaster prevention light, and disaster prevention light system according to the following embodiments have many points in common with the first embodiment, so the differences from the first embodiment will be mainly described.

[0033] Embodiment 2 3 is a diagram for explaining the configuration of a microcomputer writing adapter 102 according to the second embodiment. The microcomputer writing adapter 102 is an external device connected to the communication connector 14 of the disaster prevention light lighting device 50. The microcomputer writing adapter 102 has a communication connector 20 connected to the communication connector 14, and a USB (Universal Serial Bus) connector 22 for communicating with an external terminal device. The terminal device is, for example, a personal computer 24. The terminal device may be a tablet, a smartphone, or the like.

[0034] The communication connector 20 has a power terminal 20a, a ground terminal 20b, a transmission terminal 20c, a reception terminal 20d, a reset terminal 20e, and a write terminal 20f. When the communication connector 20 and the communication connector 14 are connected, the power terminal 20a is connected to the power terminal 14a, the ground terminal 20b is connected to the ground terminal 14b, the reset terminal 20e is connected to the reset terminal 14e, and the write terminal 20f is connected to the write terminal 14f. The transmission terminal 20c is connected to the reception terminal 14d, and the reception terminal 20d is connected to the transmission terminal 14c.

[0035] The USB connector 22 is connected to a USB connector of a personal computer 24 via a USB cable 23. A signal received from the personal computer 24 is converted by the USB interface circuit 21 and transmitted from the communication connector 20 to the disaster prevention light lighting device 50.

[0036] The power supply terminal 20a and the ground terminal 20b may receive power from the USB interface circuit 21 or from the disaster prevention light 100.

[0037] Let us assume that the communication connector 20 of the microcomputer writing adapter 102 is connected to the communication connector 14 of the disaster prevention light 100, and a microcomputer writing program is started on the personal computer 24. As a result, new software is written to the microcomputer 9 of the disaster prevention light 100 via the reset terminal 14e and write terminal 14f of the communication connector 14. In this way, the microcomputer writing adapter 102 is an external device for writing to the microcomputer 9 via the write terminal 14f. By connecting the microcomputer writing adapter 102 to the communication connector 14, a function for writing to the microcomputer 9 can be added.

[0038] Furthermore, by connecting the microcomputer writing adapter 102 to the disaster prevention radio receiving adapter 101 of the first embodiment, software can be written to the microcomputer 16 of the disaster prevention radio receiving adapter 101. For example, the frequency used by the disaster prevention radio receiving circuit 18 can be written to the microcomputer 16 of the disaster prevention radio receiving adapter 101. In other words, the frequency of the disaster prevention radio may be written to the communication connector 15 of the disaster prevention radio receiving adapter 101 by connecting the personal computer 24 to the microcomputer writing adapter 102.

[0039] By making it possible to write the frequency of the disaster prevention radio to the microcomputer 16 of the disaster prevention radio receiving adapter 101 in this way, one adapter can be used to accommodate disaster prevention radios with different frequencies for each city, ward, town, and village. If the area in which the disaster prevention radio receiving adapter 101 will be used is known in advance, the frequency of the disaster prevention radio can be written to the microcomputer 16 at the time of shipment from the factory. The frequency of the disaster prevention radio may also be written from the disaster prevention light lighting device 50 via the communication connector 15.

[0040] In addition to the above-mentioned writing function, by starting a communication program on the personal computer 24, the microcomputer writing adapter 102 can communicate with the microcomputer 9 of the disaster prevention light 100. In other words, communication can be performed between the personal computer 24 and the microcomputer 9 of the disaster prevention light 100 via the microcomputer writing adapter 102. For this communication function, the reset terminal 20e and the writing terminal 20f are not used, but the transmission terminal 20c and the reception terminal 20d are used.

[0041] This communication makes it possible to read information stored in the microcomputer 9. The microcomputer writing adapter 102 acquires information stored in the microcomputer 9 via the transmitting terminal 14c and the receiving terminal 20d. The acquired information includes information about the operation of the disaster prevention light 100, the usage status of the rechargeable battery 5, inspection results, etc. This allows the user to check when to replace consumables such as the rechargeable battery 5, whether the appliance is malfunctioning, etc. In this way, by connecting the microcomputer writing adapter 102 to the communication connector 14, a function for reading internal information of the disaster prevention light 100 can be added.

[0042] In the present embodiment, an example has been described in which writing to and reading from a microcomputer are possible using the microcomputer writing adapter 102. However, the present invention is not limited to this, and it is sufficient that the microcomputer writing adapter 102 is capable of at least one of writing to and reading from a microcomputer.

[0043] The technical features described in each embodiment may be used in appropriate combination.
