Description

  The present invention relates to an alarm device.

  Conventionally, there has been proposed a communication device that controls blinking of a light emitting unit according to the content of information to be output, and transmits information to be output to an external device by causing the light receiving unit of the external device to receive blinking light. (For example, Patent Documents 1 to 4). Such a communication device reads out internal information and triggers when an instruction signal or the like is input from an external device, or when a predetermined operation is performed on an operation unit of the communication device. Is controlled to blink.

  Further, an alarm device that performs wireless communication using an antenna to output internal information to the outside has been proposed (see Patent Documents 5 to 7). However, in the alarm devices described in Patent Literatures 5 to 7, it is necessary to newly provide a wireless communication unit such as an antenna for wirelessly communicating internal information, and the cost increases due to an increase in the configuration of the wireless communication unit. I will invite you. In view of this, there has been proposed a device in which a communication function using light described in Patent Literatures 1 to 3 is mounted on an alarm device, and the light emitting portion of the alarm device is controlled to blink to output internal information to the outside (Patent Document 8). , 9). In such an alarm device, the light emitting unit is controlled to blink and the internal information is output to the outside, so that not only the wireless communication unit is not necessary, but also the alarm device is originally provided with a light emitting unit for performing an alarm display. Therefore, the internal information can be output to the outside by using the light emitting unit, so that a rise in cost can be suppressed.

  However, the alarms described in Patent Literatures 8 and 9 are configured to read out internal information and control blinking of a light emitting unit by requesting data from a personal computer. Therefore, a configuration for accepting the request (for example, in Patent Documents 8 and 9, for example, the amplifier 50g in FIG. 6) is required. Therefore, as described in Patent Documents 1 to 4, in order to eliminate the above-described configuration, it is conceivable to read out internal information and perform blinking control of the light emitting unit by performing a predetermined operation. Must be performed, leading to an increase in the number of steps for reading the internal information.

  The present invention has been made to solve such a conventional problem, and it is an object of the present invention to eliminate the need to include a configuration for receiving a request signal for reading internal information and blinking a light emitting unit, An object of the present invention is to provide an alarm device capable of suppressing an increase in the number of steps for reading internal information.

Accordingly, there is no need to provide a function of receiving a request signal for reading out the internal information and blinking the light emitting unit, and it is possible to suppress an increase in the number of steps for reading out the internal information. Furthermore, since the flashing control of the light emitting unit is performed during a part of the light emitting period of the light emitting unit in which the light emitting state is changed, the flashing control is lost while the light emitting unit is emitting light, and the alarm device emits light. It is possible to suppress the possibility of giving the user anxiety by performing the blinking control in a state where it should not be performed.

  Further, in the alarm device of the present invention, the blinking timing judging section may determine that the abnormality judging section judges that an abnormality has occurred in the surroundings, or that the malfunction judging section judges that a malfunction has occurred. It is preferable to determine that the blinking control unit performs the blinking control when the state performed for a predetermined time continues.

  According to this alarm device, the blinking timing determination unit determines that the blinking control unit executes the blinking control when the abnormal state or the failure state continues for a predetermined time.

  Hereinafter, the present invention will be described along preferred embodiments. The present invention is not limited to the embodiments described below, and can be appropriately changed without departing from the spirit of the present invention. In addition, in the embodiments described below, some components are not illustrated or described, but the details of the omitted technology are within a range that does not cause inconsistency with the content described below. Needless to say, a well-known or well-known technique is appropriately applied.

  Further, in the following, the alarm device will be described as an example of a gas alarm device (including a CO alarm function) for LP gas or city gas, but is not limited thereto, and may be a fire alarm or a human alarm. Alternatively, it may be of a type combining the functions of two or more alarms (for example, a gas fire alarm). Further, it may be an outlet type alarm device or a battery type alarm device. In addition, the alarm device may have a function of operating in conjunction with another alarm device.

  FIG. 1 is a front view showing an external configuration diagram of a gas alarm device according to an embodiment of the present invention, and FIG. 2 is a configuration diagram showing the inside of the gas alarm device according to an embodiment of the present invention. The gas alarm 1 shown in FIGS. 1 and 2 is a stationary alarm that outputs an alarm indicating that an abnormal state has occurred when an abnormal state such as gas leakage is detected.

  The gas alarm device 1 according to the present embodiment includes a gas sensor (sensor unit) 10, a CPU 20, a ROM 31, a RAM 32, an EEPROM 40, an audio output unit 50, a light emitting unit 60, and the like shown in FIG. The structure is covered by the case 2. On the front side of the resin case 2, for example, the detection unit 3 including the gas sensor 10 therein, the notification unit 4 including the sound output unit 50 for outputting an alarm, and the display unit including the light emitting unit 60 therein. 5 and a stop switch 6 for stopping the alarm at the time of the alarm.

  The stop switch 6 functions as a check switch when no alarm is issued. That is, if the stop switch 6 is operated when no alarm is issued, the inspection operation of the gas alarm device 1 is performed. In addition, when the gas alarm device 1 is linked to another gas alarm device 1, an interlock check operation may be performed by operating the stop switch 6 in the other gas alarm device 1. .

  When there is a gas to be detected in the surroundings, the gas sensor 10 outputs a signal corresponding to the concentration (an example of a signal corresponding to the surrounding environment). The gas sensor 10 is configured by a sensor of a semiconductor type, a contact combustion type or the like. In addition to the above-described sensor, the gas sensor 10 also has a sensor unit that outputs a signal corresponding to the concentration of the surrounding carbon monoxide (an example of a signal corresponding to the surrounding environment).

  The CPU 20 controls the entire gas alarm device 1. The CPU 20 is connected with a ROM 31 and a RAM 32. The ROM 31 is a read-only memory that stores an operation program and the like. The RAM 32 is a readable and writable memory having a work area required for processing operations of the CPU 20. By executing the program stored in the ROM 31, the CPU 20 causes the abnormality determining unit 21, the failure determining unit 22, the flash control unit 23, and the flash timing determining unit 24 to function.

  The EEPROM 40 is a non-volatile memory and stores history data of the gas alarm device 1 and the like. Specifically, the EEPROM 40 stores, for example, a gas sensor voltage, a CO concentration, an ambient temperature, a battery voltage, a gas concentration at the time of alarm, a CO concentration at the time of alarm, an alarm start time, an alarm continuation time, a failure occurrence time, a failure location, and a determination value at the time of failure determination. And information such as inspection results.

  The abnormality determining unit 21 determines whether a high concentration abnormality of carbon monoxide (example of abnormality) such as gas leakage (an example of abnormality) or incomplete combustion has occurred in the surroundings based on a signal from the gas sensor 10. It is. The abnormality determination unit 21 determines that a gas leak or a high concentration abnormality of carbon monoxide has occurred when a gas having a predetermined concentration or more is detected based on a signal from the gas sensor 10. Further, when the abnormality determination unit 21 determines that a gas leak or a high concentration abnormality of carbon monoxide has occurred, the abnormality determination unit 21 transmits a signal to that effect to the audio output unit 50 and the light emitting unit 60.

  The audio output unit 50 is configured by a speaker and a buzzer. When the abnormality determination unit 21 determines that a gas leak or a high concentration abnormality of carbon monoxide has occurred, an alarm is output to notify the occurrence of the abnormality. Things. The light emitting unit 60 is for notifying the state of the gas alarm device 1 and includes a power light emitting unit 61, a CO light emitting unit 62, and a gas light emitting unit 63 in the present embodiment. The power emitting section 61 emits light when the operating power of the gas alarm device 1 is supplied. The CO light emitting unit 62 emits light or blinks when the abnormality determination unit 21 determines that a high concentration abnormality of carbon monoxide has occurred. The gas light emitting section 63 emits light or blinks when the abnormality determining section 21 determines that gas leakage has occurred. In the present embodiment, each of the light emitting units 61 to 63 is configured by a semiconductor light emitting element.

  The failure determination unit 22 determines whether a failure has occurred in the gas alarm device 1. The failure here means a state in which the gas alarm device 1 must not be used. Accordingly, not only a failure in which no sound is output from the sound output unit 50 and a failure in which the light emitting unit 60 does not emit light, but also a determination that the expiration date of the gas alarm device 1 has expired is determined as a failure. The failure determination unit 22 detects a failure of the audio output unit 50 or the light emitting unit 60 from a voltage state when the audio output unit 50 or the light emitting unit 60 is energized, for example. Further, the failure determination unit 22 determines that the failure has expired, for example, when the value of the internal counter exceeds the expiration date (for example, 5 years) of the gas alarm device 1. Further, the failure determination unit 22 determines that a failure has occurred, for example, when the battery voltage of the battery-operated gas alarm device 1 has fallen below a predetermined voltage. Note that the failure determination target and the failure detection method are not limited to those described above, and a known or other known method may be employed.

  The blinking control unit 23 controls blinking of the light emitting unit 60 according to information output to the outside. The blink control unit 23 selects information to be output from the information stored in the EEPROM 40, and controls the light emitting unit 60 to blink according to the content of the selected information. Further, the blinking control unit 23 selects one of the power emitting unit 61, the CO light emitting unit 62, and the gas light emitting unit 63 as the light emitting unit 60 to be controlled to blink, and controls the selected light emitting units 61 to 63 to blink. Let it. In particular, in the present embodiment, the blinking control unit 23 causes each of the light emitting units 61 to 63 to blink at a frequency of 50 Hz or more at which a person cannot recognize blinking.

  The blink timing determining section 24 determines whether or not the blink control section 23 executes the blink control. The flashing timing determination unit 24 is provided when the abnormality determination unit 21 determines that an abnormality has occurred in the surrounding area, or when the failure determination unit 22 determines that a failure has occurred, It is determined that the flash control is to be executed by 23. The blink control section 23 controls the light emitting sections 61 to 63 to blink when the blink timing determining section 24 determines to execute the blink control.

  More specifically, the blinking timing judging section 24 determines whether the abnormality judging section 21 has judged that an abnormality has occurred in the surroundings or the malfunction judging section 22 has judged that a malfunction has occurred for a predetermined time. When the light emission is continued, the light emitting units 61 to 63 are controlled to blink.

  Further, the blinking control unit 23 outputs information regarding the abnormality during the light emission period of the light emitting units 61 to 63 in which the abnormality determination unit 21 determines that an abnormality has occurred in the surroundings and the light emission state is changed. The flashing control of the light emitting units 61 to 63 is performed according to the information on the abnormality. More specifically, when the abnormality determining unit 21 determines that an abnormality has occurred in the surroundings, the light emitting state of one of the light emitting units 61 to 63 is changed. For example, one or more of the light emitting units 61 to 63 shifts from a light-off state to a light-emitting state, or shifts from a light-off state to a blinking state. Alternatively, one or more of the light emitting units 61 to 63 shifts from the lighting state to the blinking state, or shifts from the blinking state to the light emitting state. The blinking control unit 23 performs blinking control during the light emitting periods of the light emitting units 61 to 63 in which the light emitting state changes. As a result, the blinking control is confused with the light emission at the time of the alarm. Further, the blinking control unit 23 outputs information on the abnormality (at least one of the gas concentration at the time of alarm, the CO concentration at the time of alarm, the alarm start time, and the alarm continuation time) because the abnormality is occurring. Thus, the light emitting units 61 to 63 are controlled to blink.

  Similarly, during the light emission period of the light emitting units 61 to 63 in which the failure state is determined by the failure determination unit 22 and the light emission state is changed, the blinking control unit 23 outputs the failure information in order to output information on the failure. Of the light emitting units 61 to 63 in accordance with the information on That is, when the failure determination unit 22 determines that a failure has occurred, the light emitting state of one of the light emitting units 61 to 63 is changed. For example, one or more of the light emitting units 61 to 63 shifts from a light-off state to a light-emitting state, or shifts from a light-off state to a blinking state. Alternatively, one or more of the light emitting units 61 to 63 shifts from the lighting state to the blinking state, or shifts from the blinking state to the light emitting state. The blinking control unit 23 performs blinking control during the light emitting periods of the light emitting units 61 to 63 in which the light emitting state changes. As a result, the blinking control is confused with the light emission at the time of failure. Further, since the blinking control unit 23 is in failure, the light emitting unit outputs information on the failure (at least one of a failure occurrence time, a failure location, and a determination value at the time of failure determination in the present embodiment). 61 to 63 are controlled to blink.

  FIG. 3 is a schematic diagram showing a receiving device that receives information from the gas alarm device 1 shown in FIG. As shown in FIG. 3, the receiving device 100 includes a receiver 110 and an external device 120. The receiver 110 is, for example, a stick-shaped receiving unit, and has a light receiving unit that receives light from the light emitting units 61 to 63. An operator or the like brings the light receiving unit of the receiver 110 close to the light emitting units 61 to 63 of the gas alarm unit 1 that are controlled to blink. Thereby, the receiver 110 receives the optical signal corresponding to the information from the gas alarm device 1 and inputs the information transmitted from the gas alarm device 1 by demodulating the optical signal. The external device 120 is a device connected to the receiver 110 via a cable, and stores and displays information input by the receiver 110.

  FIG. 4 is a flowchart illustrating a control method of the gas alarm device 1 according to the present embodiment. As shown in FIG. 4, first, the blinking timing determination unit 24 determines whether an abnormality is currently occurring, that is, whether a warning is currently being issued (S1). If it is determined that the alarm is being performed (S1: YES), the blink timing determination unit 24 determines whether the state of the alarm determined in step S1 has continued for a first predetermined time (S2). When it is determined that the light emission has been continued (S2: YES), the blink control unit 23 controls the light emitting unit 60 to blink (S3). At this time, the blinking control unit 23 controls the blinking of the light emitting unit 60 so as to output information on the current abnormality (that is, the content of the alarm). Further, a blinking control is executed so as to be mixed with the emission of the alarm. Thereafter, the processing shifts to step S4.

  If it is determined that the alarm is not being performed (S1: NO), or if it is determined that the state of the alarm is not being continued for the first predetermined time (S2: NO), the process proceeds to step S4.

  In step S4, the flicker timing determination unit 24 determines whether or not a failure is currently occurring (S4). If it is determined that the failure is occurring (S4: YES), the blink timing determination unit 24 determines that the failure state determined in step S4 is the same as the second predetermined time (the first predetermined time may be the same). It may be different) (S5). If it is determined that the light emission has continued (S5: YES), the blink control unit 23 controls the light emitting unit 60 to blink (S6). At this time, the blinking control unit 23 controls the blinking of the light emitting unit 60 so as to output information on the current failure. Further, blinking control is executed so as to be mixed with the emission of the failure notification. Thereafter, the processing shifts to step S7.

  Further, when it is determined that there is no failure (S4: NO), or when it is determined that the failure state has not continued for the second predetermined time (S5: NO), the process proceeds to step S7.

  In step S7, the blink timing determining unit 24 determines whether the inspection is being performed (S7). That is, the blink timing determination unit 24 determines whether the stop switch 6 is operated and the inspection operation is being performed. When the gas alarm device 1 is linked to another gas alarm device 1, in addition to the above, it is determined whether an interlock check operation is being performed.

  When it is determined that the inspection is being performed (S7: YES), the blinking control unit 23 controls the light emitting unit 60 to blink (S8). At this time, the blinking control unit 23 controls the blinking of the light emitting unit 60 so as to output information on the current check (check result). Further, blinking control is executed so as to be mixed with the light emission of the light emitting unit 60 that emits light at the time of inspection. Thereafter, the processing shifts to step S1.

  In step S7, it may be determined whether an initial check is automatically performed when the gas alarm device 1 is installed. The process shown in FIG. 4 is repeatedly executed at all times or at specified intervals until the gas alarm device 1 becomes inoperable such as when the power is turned off.

  FIG. 5 is a first timing chart showing a control state of the gas alarm device 1 according to the present embodiment, in which (a) shows a state where there is no alarm and no failure, and (b) shows a state at the time of gas leak alarm. Is shown. As shown in FIG. 5A, when there is no alarm and no failure, when the power supply is normal, the power light emitting unit 61 is in a lighting state, and the CO light emitting unit 62 and the gas light emitting unit 63 are in a non-lighting state. When gas leaks from such a state, the gas light emitting section 63 is controlled to blink as shown in FIG. That is, the gas light emitting section 63 is determined to have an abnormality, and the light emitting state is changed. Specifically, the CPU 20 controls the gas light emitting section 63 to blink at a cycle of 2 Hz. Further, in the present embodiment, during the light emission period of the gas light emitting unit 63 in the 2 Hz cycle, the blink control unit 23 controls the gas light emitting unit 63 to blink at a cycle of 50 Hz or more in order to output information on abnormality (gas leak).

  FIG. 6 is a second timing chart showing a control state of the gas alarm device 1 according to the present embodiment, where (a) shows a state where there is no alarm and no failure, and (b) shows a state when the gas sensor 10 has a failure. Is shown. The state shown in FIG. 6A is the same as that shown in FIG. As shown in FIG. 6B, when a failure occurs in the gas sensor 10, the power light emitting unit 61 is controlled to blink, and the CO light emitting unit 62 is controlled to be turned on. That is, the power emitting unit 61 and the CO emitting unit 62 are determined to have a failure, and the light emitting state is changed. Specifically, the CPU 20 controls the gas light emitting section 63 to blink at a cycle of 2 Hz. Further, in the present embodiment, the blinking control unit 23 controls the blinking of the power supply light emitting unit 61 at a cycle of 50 Hz or more in order to output information on a failure (failure of the gas sensor 10) during the light emission period of the power supply light emitting unit 61 at a cycle of 2 Hz. Alternatively, the blinking control unit 23 controls the blinking of the CO light emitting unit 62 at a cycle of 50 Hz or more during the light emitting period of the CO light emitting unit 62 in order to output information on the failure (failure of the gas sensor 10).

  FIG. 7 is a timing chart showing a control state of the gas alarm device 1 according to the modification, in which (a) shows a state where there is no alarm and no failure, (b) shows a state at the time of gas leak alarm, and (c). ) Indicates the state at the time of expiration failure. In the modification shown in FIG. 7A, the light emitting section 60 is configured by one light emitting element. Such a light emitting element can be switched between three states: a light-off state, a dark lighting state, and a bright lighting state.

When there is no alarm or failure in the light emitting unit 60, the light emitting unit 60 is in a dark lighting state as shown in FIG. Then, when a gas leak occurs, as shown in FIG. 7B, the light emitting unit 60 repeats the dark lighting state and the bright lighting state at a period of 3.6 Hz. At this time, the blinking control unit 23 controls the blinking of the light-emitting unit 60 at a cycle of 50 Hz or more during the light-emitting period of the light-emitting unit 60 (either in a darkly lit state or in a brightly-lit state) in order to output information on a gas leakage abnormality. The blinking control may repeat the dark lighting state and the light-off state at a cycle of 50 Hz or more as shown by reference numeral 60c , or may change the bright lighting state and the light-off state at a period of 50 Hz or more as shown by reference numeral 60a. The light-on state and the dark-on state may be repeated at a cycle of 50 Hz or more, as indicated by reference numeral 60b . That is, the blinking control is not limited to the case of repeating lighting and extinguishing, but includes a concept of repeating a state in which brightness is different.

  Further, when the expiration date has occurred, as shown in FIG. 7C, the light emitting unit 60 repeats the dark lighting state of 2 seconds and the light-off state of 1 second. At this time, during the light emitting period (dark lighting state) of the light emitting unit 60, the blinking control unit 23 controls the light emitting unit 60 to blink at a cycle of 50 Hz or more in order to output information on the expiration failure.

  Although the details of the blinking control at the time of gas leakage, the failure of the gas sensor 10, and the failure of the expiration date have been described above with reference to FIGS. 5 to 7, the same applies to other abnormalities and failures. The blinking control during the inspection operation is the same as that shown in FIGS.

  As described above, according to the gas alarm device 1 according to the present embodiment, since the flash alarm timing determination unit 24 that determines that the flash control unit 23 performs the flash control at the time of occurrence of an abnormality or a failure is provided, There is no need to transmit a signal or operate the gas alarm device 1, and the gas alarm device 1 controls the light emitting unit 60 to blink on and off according to its own judgment. Therefore, there is no need to provide a function of receiving a request signal for reading out the internal information and blinking the light emitting unit 60, and it is possible to suppress an increase in the number of steps for reading out the internal information.

  In addition, the blinking timing determination unit 24 determines that the blinking control unit 23 executes the blinking control when the abnormal state or the failure state continues for a predetermined time. , The blinking control can be executed in the case of a certain abnormal state or failure state in which the abnormal state or failure state continues for a predetermined time.

  In addition, since the flashing control of the light emitting unit 60 is performed during the light emitting period of the light emitting unit 60 in which the light emitting state is changed when it is determined that an abnormality has occurred in the surroundings, the flashing control is performed while the light emitting unit 60 emits light. Can be confused, and the possibility of giving anxiety to the user by performing blinking control in a state where the gas alarm device 1 should not emit light can be suppressed. Further, since the blinking control of the light emitting unit 60 according to this information is performed so as to output information regarding the abnormality, the details of the abnormality can be output to the outside when the gas alarm device 1 is alerting the abnormality, The details of the abnormality can be output to the outside.

  In addition, since the blinking control of the light emitting unit 60 is performed during the light emitting period of the light emitting unit 60 in which the failure is determined to have occurred and the light emitting state is changed, the blinking control is mistaken while the light emitting unit 60 emits light. As a result, it is possible to suppress the possibility of giving the user anxiety by performing the blinking control when the gas alarm device 1 should not emit light. Further, since the blinking control of the light emitting unit 60 according to this information is performed to output information regarding the failure, when the gas alarm device 1 has failed, the content of the failure can be output to the outside, and Details can be output externally.

  As described above, the present invention has been described based on the embodiments. However, the present invention is not limited to the above-described embodiments, and may be modified without departing from the spirit of the present invention. May be combined.

  For example, in the above embodiment, the light emitting units 60, 61, 62, and 63 are configured by light emitting elements, but are not limited thereto, and are not limited to light emitting elements as long as they can emit light. For this reason, the light-emitting unit 60 may be a backlight of a liquid crystal display or another object.
