Description

  The present invention notifies the alarm state or failure state by voice or display when detecting the alarm state or failure state, and also indicates the alarm indicated by the notification signal when the notification signal indicating the content of the alarm state or failure state is input from the outside. The present invention relates to an alarm device that notifies a state or a failure state by voice or display, and a battery-driven wireless device that is connected to the alarm device and wirelessly transmits and receives information to and from other wireless devices.

  For example, in the field of gas leak alarms, conventionally, a plurality of gas leak alarms are connected to each other, and when a gas leak is detected by a gas leak alarm and an alarm is output, Also in this gas leak alarm device, there is known one that outputs an alarm for notifying the detection of gas leak in another gas leak alarm device (for example, Patent Document 1).

The connection between gas leak alarms as described above was generally performed by wired connection, but in recent years, with the increase in the size of houses where gas leak alarms are installed, long-distance wiring has been established. It is conceivable that a wireless connection, which is also used for the connection between the gas meter and the gas leak alarm, is used so that it is not necessary.

  However, since the wireless device used to enable the above-described configuration generally uses an internal battery as a power source, a warning can be given by another gas leak alarm device other than the gas leak alarm device that detects a gas leak. Even if the battery is configured to be able to output, if the battery is in an insufficient state, the alarm is not output in the other gas leak alarm due to the fact that the wireless communication is stopped. It can no longer be achieved.

  That being said, it is not preferable to provide an alarm output function by voice or display such as a gas leak alarm in the radio apparatus itself, because this will increase the cost of the radio apparatus.

A remaining amount detecting means A for detecting the remaining amount of the battery V or a physical amount corresponding to the remaining amount, and a remaining amount of the battery V detected by the remaining amount detecting means A or a physical amount corresponding to the remaining amount. Is a predetermined threshold The remaining amount decrease determining means B for determining whether or not the remaining amount of the battery V has been decreased, and the remaining amount of the battery V detected by the remaining amount detecting means A or a physical quantity corresponding to the remaining amount is decreased to a predetermined threshold value. When the remaining amount decrease determination means B determines that the remaining amount of battery B has been decreased, a remaining amount decrease signal for notifying the state of the remaining amount of the battery V by voice or display is output to the connected alarm devices 1 and 4. And a remaining amount drop notification means C.

To notify by voice or display The remaining amount decrease signal, configured to output to said alarm device 1,4 are connected to.

Furthermore, alarm of the present invention as set forth in claim 3, as described in the basic configuration diagram of FIG. 2, are sent and received information by radio between the other wireless devices 2,3 Noto, voice or It is connected to the battery-driven wireless devices 2 and 3 that do not have an alarm output function by display, and when the alarm state or failure state is detected, the alarm state or failure state is notified by voice or display, and the alarm state or A notification signal indicating the content of the failure state is output to the wireless devices 2 and 3 at the connection destination, and the alarm state or failure indicated by the notification signal when the notification signal is input from the wireless devices 2 and 3 at the connection destination An alarm device for notifying the state by voice or display, and a remaining amount decrease for notifying the remaining state of the drive battery V in the wireless devices 2 and 3 from the connected wireless devices 2 and 3 When the signal is input, the remaining low signal And further comprising a low battery alarm means F for notifying the power low state by voice or display of the driving battery V in the radio devices 2 and 3 of the destination indicated by.

According to the wireless device of the present invention described in claim 1, there is no voice or display alarm output function connected to the alarm devices 1, 4, and wireless information is transmitted to and received from other wireless devices. When the remaining amount of the battery V detected by the remaining amount detecting means A or the physical quantity corresponding to the remaining amount of the wireless device is reduced to a predetermined threshold, the remaining amount lowering determining means B determines that A remaining amount decrease signal for notifying the state of the remaining amount of the battery V by voice or display is output to the connected alarm devices 1 and 4 by the remaining amount decrease notification means C.

  For this reason, the alarm device 1 or 4 connected to the wireless device informs that the remaining amount of the battery V of the wireless device or the physical quantity corresponding to the remaining amount has decreased to a predetermined threshold value by voice or display. Thus, even if the wireless device itself does not have a configuration for notification, it is possible to efficiently recognize the battery voltage drop state of the wireless device.

  FIG. 3 is a block diagram showing a first embodiment of an automatic linkage system in which the present invention is applied to mutually connect gas leak alarms wirelessly, and FIG. 4 is a configuration example of a wireless unit in the automatic linkage system of FIG. FIG.

  The automatic cooperation system of this embodiment shown in FIG. 3 includes gas leak alarms 1 and 4 (corresponding to the alarms in the claims) and wireless units 2 and 3 connected to the gas leak alarms 1 and 4 respectively. (Corresponding to the wireless device in the claims). The gas leak alarms 1 and 4 and the wireless units 2 and 3 are installed at different locations in one building, and the wireless units 2 and 3 perform wireless communication with each other to perform a mutual alarm operation.

  The gas leak alarms 1 and 4 are conventionally known ones that generate gas and output an alarm signal (corresponding to a notification signal in claims) by detecting gas by a sensor that detects components of city gas and propane gas. Incorporates a function to notify by sound (alarm sound, alarm message) at the time of detection.

  Note that the sound notification function of the gas leak alarms 1 and 4 is not limited to the case where it detects a gas leak or a fire, but also a signal input from the outside via the wireless units 2 and 3 (other wireless The alarm can also be activated by an alarm notification signal based on an alarm signal output from the gas leak alarms 1 and 4 connected to the units 2 and 3.

  The main part of the specific processing performed by the microcomputer (not shown) included in the gas leak alarm 1, 4 that performs the above operation is as shown in the flowchart of FIG.

  First, it is confirmed whether or not a gas leakage state has been detected (step S1). If it is detected (Y in step S1), the fact that the gas leakage has been detected is notified by voice output (step S3), and the gas leakage is detected. Is generated and output to the port Pio of the connected wireless units 2 and 3 (step S5), the process returns to step S1.

  On the other hand, when the gas leak state is not detected (N in step S1), it is confirmed whether or not an alarm signal is input from the connected wireless units 2 and 3 via the port Pio (step S7). If it is input (Y in step S7), it is notified by voice output that the other gas leak alarms 1 and 4 have detected the gas leak (step S9), and then the process returns to step S1.

  If no alarm signal is input from the connected wireless units 2 and 3 via the port Pio in step S7 (N), the remaining wireless units 2 and 3 via the port Pio remain. It is confirmed whether or not an amount reduction signal has been input (step S11). If not input (N in step S11), the process returns to step S1.

  On the other hand, when the remaining amount decrease signal is input from the connected wireless units 2 and 3 (Y in step S11), the input remaining amount decrease signal is the battery V of the connected wireless units 2 and 3. It is confirmed whether or not this indicates a voltage drop state (step S13).

  If it indicates a voltage drop state of the battery V in the connection-destination wireless units 2 and 3 (Y in step S13), a voice indicating that the voltage of the battery V is in a drop state in the connection-destination wireless units 2 and 3 is given. After notifying by the output (step S15), the process returns to step S1, and indicates a voltage drop state of the battery V in the other wireless units 2 and 3 different from the connected wireless units 2 and 3 ( In step S13, N), after notifying by voice output that the voltage of the battery V is in a lowered state in the wireless units 2 and 3 other than the connection destination (step S17), the process returns to step S1.

  As is clear from the above description, in the gas leak alarms 1 and 4 of this embodiment, steps S11 to S15 in the flowchart of FIG. Step S11, step S13, and step S17 in FIG. 5 are processes corresponding to the second battery remaining amount lowering notification means G in the claims.

  As shown in FIG. 4, the radio units 2 and 3 include a communication high-frequency circuit unit RF, a modulation / demodulation processing digital processing circuit unit DP, and a control microcomputer unit (hereinafter abbreviated as “microcomputer unit”) μCOM. One-chip integrated circuit LSI, a port Pio to which gas leak alarms 1 and 4 are connected, a non-volatile memory NVM, an antenna AT connected to the communication high-frequency circuit unit RF, and a battery V as a power source And an A / D converter CONV for A / D converting the voltage of the battery V, and the A / D converter CONV and the nonvolatile memory NVM are connected to the microcomputer unit μCOM.

  In the nonvolatile memory NVM, the self-identification information used by the wireless units 2 and 3 in the wireless communication with the outside, and the pulse waveform pattern of the alarm signal output from the gas leak alarms 1 and 4 are indicated by this. A table that associates alarm contents (for example, gas leakage, fire occurrence, etc.) is registered in advance.

  Then, in the microcomputer unit μCOM, according to the control program stored in the internal ROM (not shown), the battery remaining amount notification process (step S19) and the communication process (step S21) shown in the flowchart of the main routine of FIG. And are executed repeatedly.

  Among these, in the battery remaining amount notification process in step S19, as shown in the flowchart of the subroutine of FIG. 7, the voltage level of the battery V is determined from the digital value of the voltage of the battery V input via the A / D converter CONV. Is detected (step S19a), and it is confirmed whether or not the detected voltage level is lowered to a predetermined threshold (step S19b).

  If the detected voltage level of the battery V has not decreased to a predetermined threshold value (N in step S19b), the battery remaining amount notification process is terminated, and the process proceeds to the communication process of step S21 in the flowchart of FIG. .

  On the other hand, when the detected voltage level of the battery V has dropped to a predetermined threshold (Y in step S19b), the fact that the voltage of the battery V is in a lowered state is connected to the port Pio. The gas leak alarms 1 and 4 generate a remaining amount decrease signal for notification by voice output, and output the signal from the port Pio to the gas leak alarms 1 and 4 (step S19c), and the content of the generated remaining amount decrease signal The remaining amount data indicating that the voltage of the battery V is in a lowered state is modulated by the modulation / demodulation processing digital processing circuit DP together with its own identification information registered in the nonvolatile memory NVM for communication. After wireless transmission from the high-frequency circuit unit RF or the antenna AT (step S19d), the battery remaining amount notification process is terminated, and the communication process of step S21 in the flowchart of FIG. Row.

  In the communication process of step S21, as shown in the flowchart of the subroutine of FIG. 8, it is confirmed whether or not the alarm signal from the gas leak alarms 1 and 4 is input to the port Pio (step S21a). (Y in step S21a), referring to the table registered in the non-volatile memory NVM, discriminates the alarm content generated from the pulse waveform pattern of the input alarm signal (step S21b).

  Then, the alarm generation data indicating the alarm content of the determined alarm signal is modulated by the modulation / demodulation processing digital processing circuit DP together with its own identification information registered in the nonvolatile memory NVM, and the communication high-frequency circuit unit RF to After wireless transmission from the antenna AT (step S21c), the communication process is terminated, and the process proceeds to the battery remaining amount notification process of step S19 in the flowchart of FIG.

  On the other hand, when the alarm signal from the gas leak alarms 1 and 4 is not input to the port Pio in step S21a (N), the alarm generation data from the other radio units 2 and 3 are transmitted from the antennas AT to AT. It is confirmed whether it has been received by the communication high-frequency circuit unit RF and demodulated by the modulation / demodulation processing digital processing circuit unit DP (step S21d).

  When alarm generation data from other wireless units 2 and 3 is input (Y in step S21d), the alarm state indicated in the alarm generation data is the other wireless unit at another location in the same building. Generating an alarm notification signal for notifying the occurrence of gas leak alarms 1 and 4 connected to ports 2 and 3 by voice output in the gas leak alarms 1 and 4 connected to the port Pio; After outputting from the port Pio to the gas leak alarms 1 and 4 (step S21e), the communication process is terminated, and the process proceeds to the battery remaining amount notification process of step S19 in the flowchart of FIG.

  On the other hand, when alarm generation data from the other wireless units 2 and 3 is not input (N in step S21d), the remaining amount reduction data from the other wireless units 2 and 3 is transmitted from the antenna AT to the communication high-frequency circuit. It is confirmed whether it is received by the unit RF and demodulated and input by the digital processing circuit unit DP for modulation / demodulation processing (step S21f). If not input (N in step S21f), the communication processing is terminated. Then, the process proceeds to a battery remaining amount notification process in step S19 in the flowchart of FIG.

  On the other hand, when remaining amount reduction data is input from the other wireless units 2 and 3 (Y in step S21f), the other wireless units 2 and 3 installed in other locations in the same building The gas leakage alarms 1 and 4 connected to the port Pio generate a remaining amount lowering signal to notify the fact that the voltage of the battery V is in a lowered state, and the gas leakage alarm is output from the port Pio. After output to the devices 1 and 4 (step S21g), the communication process is terminated, and the process proceeds to the battery remaining amount notification process of step S19 in the flowchart of FIG.

  As is apparent from the above description, in the wireless units 2 and 3 of the present embodiment, step S19a in the flowchart of FIG. 7 is processing corresponding to the remaining amount detection means A in the claims. Step S19b is a process corresponding to the remaining amount decrease determining means B in the claims, and step S19c in FIG. 7 is a process corresponding to the remaining amount decrease notifying means C in the claims. It has become.

  Further, in the wireless units 2 and 3 of the present embodiment, step S19d in FIG. 7 is a process corresponding to the remaining amount reduction data transmitting means D in the claims, and step S21f in FIG. This is processing corresponding to the remaining amount data receiving means E in the claims.

  Next, the operation (action) of the automatic linkage system of the present embodiment configured as described above will be described.

  First, when an alarm state is detected in the gas leak alarms 1 and 4, an alarm is output by voice or the like, and an alarm signal having a different pulse waveform pattern is generated depending on the detected alarm state. Is output.

  Then, in the wireless units 2 and 3 to which the alarm signal is input from the port Pio, alarm generation data indicating the alarm content indicated by the pulse waveform pattern of the alarm signal is transmitted by wireless communication.

  In the other wireless units 2 and 3 that have received this alarm generation data, an alarm notification signal is output to the gas leak alarms 1 and 4 connected to the radio unit 2 and 3 and the alarm state is detected. In the gas leak alarms 1 and 4 installed in the same building as 1 and 4, the alarm state notification operation generated in the other gas leak alarms 1 and 4 is performed using the voice notification function.

  Further, when the voltage of the battery V drops to a predetermined threshold value in the wireless units 2 and 3, the gas leak alarms 1 and 4 connected to the wireless units 2 and 3 connect to the wireless unit 2 connected to itself. , 3 that the battery V is in a low voltage state is performed using the voice notification function, and also in the other gas leak alarms 1, 4 connected to the other wireless units 2, 3, In the other wireless units 2 and 3 that are not connected to the wireless units 2 and 3, a notification operation that the battery V is in a voltage drop state is performed using the voice notification function.

  As described above, according to the automatic linkage system of the present embodiment, the wireless units 2 and 3 themselves can be connected to the wireless units 2 and 3 without the voice notification function. It is possible to make a notification using the voice notification function of the gas leak alarms 1 and 4 connected to.

  The configuration for notifying the voltage drop state is also omitted in the gas leak alarms 1 and 4 connected to the other wireless units 2 and 3 other than the wireless units 2 and 3 in which the voltage of the battery V is lowered. However, if this configuration is provided, the voltage drop of the battery V in the wireless units 2 and 3 installed in other places, even in places other than the place where the wireless units 2 and 3 in which the voltage of the battery V has dropped is provided. It is advantageous because the state can be grasped.

  Moreover, the alarm device connected to the wireless device to which the present invention is applied outputs an alarm signal when an alarm state occurs, such as the gas leak alarm devices 1 and 4 and the fire alarm device described in the above-described embodiment. For example, an alarm device that periodically detects a failure state of an internal circuit or sensor and outputs a notification signal to the wireless device (external) may be used.

  And the alarm status or failure status notification performed by the alarm device may be not only by voice but also by display or the like, and even such an alarm device can be an application target of the present invention. Needless to say.
