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 a wireless device that is connected to an alarm device that notifies a state or a failure state by voice or display, and that performs wireless transmission and reception of information with a plurality of 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 the 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.
JP-A-62-50998

  By the way, the wireless communication between the gas leak alarms using the above-described wireless device is specifically the alarm state from the gas leak alarm that detects the gas leak or its elimination to the other gas leak alarms. However, if this signal is not reliably received by the other party's wireless device, the other gas leak alarm will recognize the gas leak status detected by one gas leak alarm and its elimination. Therefore, it is impossible to notify or end the notification on its own, so that it is necessary to devise measures to prevent such a situation.

  And this problem is not limited to the case of connecting multiple gas leak alarms to each other, but when the alarm status or fault status is detected such as a fire alarm or a security alarm (window sensor, etc.) This is widely applicable when alarm devices that are notified by voice or display are connected and operated using a wireless device.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to connect a plurality of alarm devices that notify the state by voice or display at the time of detection of an alarm state or a failure state to each other via a wireless device. In addition, the alarm state or failure state detected by a certain alarm device can be notified not only by itself but also by other alarm devices through the wireless communication between each alarm device via a wireless device, or the alarm state in the detection source alarm device Or, when the detection of the failure state is completed, the alarm state or failure detected by the other alarm devices may be detected even if the wireless communication between the alarm devices is interrupted in terminating the alarm state or failure state notification in the other alarm devices. An object of the present invention is to provide a wireless device that can reliably notify the wireless device connected to another alarm device of the end of the state.

In order to achieve the above object, the wireless device of the present invention described in claim 1 is a notification signal indicating the contents of the alarm state or failure state when the alarm state or failure state is detected, as shown in the basic configuration diagram of FIG. Is connected to alarm devices 1, 4, 5, and 8 that notify the alarm state or failure state indicated by the notification signal by voice or display , and the alarm devices 1, 4, 5, and 8 output the A wireless device that wirelessly transmits / receives data corresponding to the content indicated by the notification signal to / from other wireless devices, and during input of the notification signal, every predetermined time from the start of input of the notification signal, First transmission means A for wirelessly transmitting start data indicating the start of the alarm state or failure state indicated by the notification signal to a plurality of other wireless devices, and when the input of the notification signal ends, the notification signal indicates Solution of the alarm state or failure state The second transmission means B for wirelessly transmitting the release data indicating to the plurality of other wireless devices, and a second predetermined time longer than the predetermined time from the previous reception of the start data from the other wireless devices. Until the elapse of time, re-reception determination means C for determining whether or not the start data is re-received from another wireless device, and the connection to the other wireless device in response to the start of reception of the start data An interlock notification signal for causing the alarm devices 1, 4, 5, and 8 at the connection destination to notify the alarm devices 1, 4, 5, and 8 regarding the alarm devices 1, 4, 5, and 8 is connected to the alarm device 1, the connection destination. The interlocking notification means D that outputs to 4, 5 and 8 and the other wireless device between the previous reception of the start data from the other wireless device and the elapse of a second predetermined time longer than the predetermined time. If there is no re-reception of the start data, the re-reception determining means C And when the release data is received, it is provided with linked notification end means E for terminating the output of the linked notification signal to the connected alarm devices 1, 4, 5 and 8. And

  According to the wireless device of the present invention described in claim 1, from the first transmission means A of the wireless device to which the alarm devices 1, 4, 5, and 8 that output the notification signal are connected, at the start of output of the notification signal When the start data is output, the link notification means D of the other wireless device that has received the start data outputs a link notification signal to the connected alarm devices 1, 4, 5, and 8 every predetermined time, In the alarm devices 1, 4, 5, and 8 of the output destination, the alarm state or failure state regarding the alarm devices 1, 4, 5, and 8 connected to other wireless devices is notified.

  Then, with the termination of the output of the notification signal, when the release data is output from the second transmission means B of the wireless device to which the alarm devices 1, 4, 5, and 8 that output the ended notification signal are connected, Upon receiving this, the interlocking notification end means E of the other wireless device ends the output of the interlocking notification signal to the connected alarm devices 1, 4, 5 and 8, and the output destination alarm devices 1, 4, 5 , 8, the alarm state or the failure state notification regarding the alarm devices 1, 4, 5, 8 connected to other wireless devices is terminated.

  Also, a predetermined time that is the output time of the next start data from the reception of the start data output last time from the first transmission means A of the wireless device to which the alarm devices 1, 4, 5, and 8 that output the notification signal are connected. If the next start data is not received again before the second predetermined time elapses after the reception of the previously output start data further after the elapse of time, the other wireless device is also informed Termination means E terminates the output of the interlock notification signal to the connected alarm devices 1, 4, 5, and 8 and is connected to other wireless devices in the output alarm devices 1, 4, 5, and 8. That is, the alarm state or failure state notification regarding the alarm devices 1, 4, 5, and 8 is terminated.

  Therefore, the wireless communication between the wireless device from which the start data is output and the other wireless device is hindered, and the release data output from the second transmission means B of the wireless device from which the start data is output cannot be received. However, since the next start data is not received, the alarms 1, 4, 5, and 8 of the connection destinations connected by the output of the interlock notification signal by the interlock notification means D are connected to other wireless devices. The notification of the alarm state or failure state regarding the alarm devices 1, 4, 5, and 8 can be surely terminated without continuing unnecessarily.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 2 is a block diagram showing an embodiment of an automatic linkage system in which the present invention is applied to mutually connect gas leak alarms wirelessly, and FIG. 3 shows a configuration example of a wireless device in the automatic linkage system of FIG. It is a block diagram.

  The automatic cooperation system of the present embodiment shown in FIG. 2 includes gas leak alarms 1, 4, 5, and 8 (corresponding to alarms in claims) and gas leak alarms 1, 4, 5, and 8, respectively. And connected wireless devices 2, 3, 6, and 7. The gas leak alarms 1, 4, 5, and 8 and the wireless devices 2, 3, 6, and 7 are installed at different locations in one building, and the wireless devices 2, 3, 6, and 7 perform wireless communication with each other. Thus, the alarm mutual notification operation is performed.

  Gas leak alarms 1, 4, 5, and 8 are conventionally known in which gas is detected by a sensor that detects a component of city gas or propane gas, and an alarm signal (corresponding to a notification signal in claims) is generated and output. While detecting a gas leak, it has a function to notify the gas leak by sound (alarm sound, alarm message) and a function to output an alarm signal to notify the outside that a gas leak has been detected. Built-in.

  The sound alarm function of the gas leak alarms 1, 4, 5, and 8 is not limited to the case where it detects a gas leak or a fire, but from the outside via the wireless devices 2, 3, 6, and 7. It can also be activated by an input signal (alarm notification signal based on an alarm signal output from gas leak alarms 1, 4, 5, 8 connected to other wireless devices 2, 3, 6, 7). it can.

  As shown in FIG. 3, the wireless devices 2, 3, 6, and 7 are abbreviated as a communication high-frequency circuit unit RF, a modulation / demodulation processing digital processing circuit unit DP, and a control microcomputer unit (hereinafter referred to as “microcomputer unit”). ) Integrated circuit LSI in which μCOM is integrated into one chip, port Pio to which gas leak alarms 1, 4, 5, and 8 are respectively connected, a non-volatile memory NVM, and an antenna connected to a communication high-frequency circuit unit RF The A / D converter CONV and the nonvolatile memory NVM are connected to the microcomputer unit μCOM.

  In the nonvolatile memory NVM, self-identification information used by the wireless devices 2, 3, 6, and 7 in wireless communication with the outside is registered in advance.

  In the microcomputer unit μCOM, the processes shown in the flowcharts of FIGS. 4 to 6 are executed in accordance with a control program stored in an internal ROM (not shown).

  First, it is confirmed whether or not the alarm signal from the gas leak alarm 1, 4, 5 and 8 has started to be input to the port Pio (step S1). If the input has not started (N in step S1) ), The process proceeds to step S7 to be described later, and when the input is started (Y in step S1), alarm generation data (corresponding to the start data in the claims) indicating the generation of the alarm state is stored in the nonvolatile memory NVM. Along with the registered self-identification information, the modulation / demodulation processing digital processing circuit unit DP modulates the signal and wirelessly transmits it three times from the communication high frequency circuit unit RF to the antenna AT (step S3). After the alarm output flag F1 provided in the RAM (not shown) is set to “1” (step S5), the process proceeds to step S7.

  In step S7, whether the alarm generation data from the other radio devices 2, 3, 6, 7 has been received by the antenna AT or the communication high-frequency circuit unit RF and demodulated by the modulation / demodulation processing digital processing circuit unit DP is input. If not input (N in Step S7), the process proceeds to Step S19 described later. If input (Y in Step S7), the identification information input together with the alarm occurrence data is stored in the RAM. (Step S9), it is checked whether or not the alarm notification signal output flag F3 provided in the RAM is “0” (step S11).

  If the alarm notification signal output flag F3 is not “0” (N in step S11), the process proceeds to step S19. If it is “0” (Y in step S11), the alarm notification signal output flag F3 is set to “1”. (Step S13), it is confirmed whether or not the alarm output flag F1 in the RAM is “0” (step S15). If it is not “0” (N in step S15), the process proceeds to step S19. .

  On the other hand, if the alarm output flag F1 is “0” (Y in step S15), the gas leak alarm 1 connected to the other wireless devices 2, 3, 6, and 7 at other locations in the same building. , 4, 5, 8, an alarm notification signal for notifying the gas leak alarm devices 1, 4, 5, 8 connected to the port Pio by sound output (interlocking in claims) (Corresponding to a notification signal) is generated and output from the port Pio to the gas leak alarms 1, 4, 5, and 8 is started (step S17), and then the process proceeds to step S19.

  In step S19, as shown in the flowchart of FIG. 5, alarm cancellation data from the other radio apparatuses 2, 3, 6, and 7 is received by the antenna AT or the communication high-frequency circuit unit RF, and the modulation / demodulation processing digital processing circuit unit It is confirmed whether or not the signal has been demodulated and input by the DP. If it has been input (Y in step S19), the process proceeds to step S25 described later. If it has not been input (N in step S19), in step S7. It is confirmed whether or not 4 minutes have elapsed since the alarm generation data was input from the other confirmed wireless devices 2, 3, 6, and 7 (step S21).

  If 4 minutes have elapsed from the input of the alarm generation data (Y in step S21), the process proceeds to step S25, and if 4 minutes have not elapsed (N in step S21), the alarm output flag F1 in the RAM is “0”. ”(Step S23), if it is“ 0 ”(Y in step S23), the process returns to step S1, and if it is not“ 0 ”(N in step S23), a step described later Proceed to S37.

  In step S25, the identification information input together with the alarm release data from the other wireless devices 2, 3, 6 and 7 in step S19, or the identification information input together with the alarm generation data after 4 minutes from the input in step S21. Information is deleted from the alarm management area in the RAM, and it is confirmed whether or not any identification information is written in the alarm management area in the RAM (step S27).

  When even one piece of identification information is written in the alarm management area (Y in step S27), it is confirmed whether or not the alarm output flag F1 in the RAM is “0” (step S29). If it is (Y in Step S29), the process returns to Step S1, and if it is not “0” (N in Step S29), the process proceeds to Step S37.

  On the other hand, if no identification information is written in the alarm management area (N in Step S27), the alarm notification signal output flag F3 in the RAM is set to “0” (Step S31), and the alarm output in the RAM is set. It is confirmed whether or not the flag F1 is “0” (step S33). If it is “0” (Y in step S33), the gas leak alarms 1, 4, 5, are output from the port Pio of the alarm notification signal. 8 is finished (step S35), the process returns to step S1, and if it is not “0” (N in step S33), the process proceeds to step S37.

  In step S37, as shown in the flowchart of FIG. 6, it is confirmed whether or not the alarm signal from the gas leak alarms 1, 4, 5, and 8 is continuously input to the port Pio, and the input is continued. If not (N in step S37), the alarm cancellation data indicating the cancellation of the alarm state (corresponding to the cancellation data in the claims) is added to the modulation / demodulation processing digital together with its own identification information registered in the nonvolatile memory NVM. Modulated by the processing circuit unit DP and wirelessly transmitted three times from the communication high-frequency circuit unit RF to the antenna AT (step S39), the RAM alarm output flag F1 is set to “0” (step S41), It is confirmed whether or not the alarm notification signal outputting flag F3 in the RAM is “0” (step S43).

  If the alarm notification signal output flag F3 is “0” (Y in step S43), the process returns to step S1, and if it is not “0” (N in step S43), the alarm notification signal (linked in the claims) (Corresponding to a notification signal) is generated and output from the port Pio to the gas leak alarms 1, 4, 5, 8 is started (step S45), and then the process returns to step S1.

  In step S37, if the alarm signal from the gas leak alarms 1, 4, 5, 8 continues to be input to the port Pio (Y), 3 minutes from the transmission of the alarm occurrence data in step S3. It is confirmed whether or not it has elapsed (step S47). If it has not elapsed (N in step S47), the process returns to step S7, and if it has elapsed (Y in step S47), an alarm indicating the occurrence of an alarm state The generated data (corresponding to the start data in the claims) is modulated by the modulation / demodulation processing digital processing circuit section DP together with its own identification information registered in the nonvolatile memory NVM, and the communication high frequency circuit section RF or antenna After the wireless transmission is repeated three times from the AT (step S49), the process returns to step S7.

  As is clear from the above description, in the wireless devices 2, 3, 6, and 7 of the present embodiment, steps S1 and S3 in the flowchart of FIG. 4 and steps S37, S47 in the flowchart of FIG. Step S49 is processing corresponding to the first transmission means A in the claims, and steps S37 and S39 in FIG. 6 are processing corresponding to the second transmission means B in the claims. It has become.

  Further, in the wireless devices 2, 3, 6, and 7 of the present embodiment, step S21 in the flowchart of FIG. 5 is processing corresponding to the re-reception determination means C in the claims, and in FIG. Step S7, Step S17, and Step S45 in FIG. 6 are processing corresponding to the interlocking notification means D in the claims, and further, Step S19, Step S21, and Step S35 in FIG. However, the processing corresponds to the interlocking notification ending 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 each of the gas leak alarms 1, 4, 5, and 8, the alarm output by voice or the like is started by itself, and an alarm signal for notifying the detection of the alarm state is sent to the wireless device. 2, 3, 6 and 7.

  Then, in the wireless devices 2, 3, 6, and 7 to which alarm signals are input from the connected gas leak alarm devices 1, 4, 5, and 8, alarm generation data indicating the occurrence of an alarm state is transmitted to the wireless devices 2 and 2. It is repeatedly transmitted three times by wireless communication together with the identification information of 3, 6, and 7.

  In the other wireless devices 2, 3, 6, and 7 that have received the alarm occurrence data transmitted repeatedly three times, other than the gas leak alarm devices 1, 4, 5, and 8 that detected the current alarm state The alarm state is not yet detected in the gas leak alarms 1, 4, 5, and 8, and the alarm signal accompanying the detection of the alarm condition is received from the gas leak alarms 1, 4, 5, and 8 connected to itself. If it is not input, the output of the alarm notification signal to the gas leak alarms 1, 4, 5, and 8 connected to itself is started, and the connected gas leak alarm 1, In 4, 5 and 8, the notification operation using the voice notification function of the alarm state generated in the other gas leak alarm devices 1, 4, 5 and 8 is started.

  Then, in the wireless devices 2, 3, 6, and 7 that repeatedly transmitted the alarm generation data three times by wireless communication, the alarm signal input from the gas leak alarm devices 1, 4, 5, and 8 connected to the wireless devices continues. During this period, the alarm generation data is repeatedly transmitted three times by wireless communication every 3 minutes.

  Moreover, when the alarm state detected in each gas leak alarm 1, 4, 5, and 8 ends, the alarm output by the voice etc. performed by itself is terminated, and an alarm for notifying the detection of the alarm state The output of the signal to the wireless devices 2, 3, 6, and 7 is terminated.

  Then, in the wireless devices 2, 3, 6, and 7 where the input of the alarm signal from the connected gas leak alarm devices 1, 4, 5, and 8 is finished, the alarm release data indicating the release of the alarm state is the wireless device. It is repeatedly transmitted three times by wireless communication together with the identification information of 2, 3, 6, and 7.

  In the other wireless devices 2, 3, 6, and 7 that have received the alarm release data, the other gas leak alarm devices 1, 4 other than the gas leak alarm devices 1, 4, 5, and 8 that have detected the alarm state this time. , 5, 8, if the alarm state is still detected, the output of the alarm notification signal to the gas leak alarm devices 1, 4, 5, 8 connected to itself is continued, and the connected gas leak alarm device 1 4, 4, 5, 8, the notification operation using the voice notification function of the alarm state generated in the other gas leak alarm devices 1, 4, 5, 8 is continued.

  On the other hand, if the alarm state is not detected in other gas leak alarm devices 1, 4, 5, and 8 other than the gas leak alarm devices 1, 4, 5, and 8 for which the detection of the alarm state has been completed this time, it is connected to itself. The output of the alarm notification signal to the gas leak alarm devices 1, 4, 5, and 8 is terminated, and the other gas leak alarm devices 1 that have been performed in the connected gas leak alarm devices 1, 4, 5, and 8 are performed. , 4, 5 and 8, the notification operation using the voice notification function in the alarm state is terminated.

  Even if the alarm release data is not received, it is transmitted every 3 minutes from the radio devices 2, 3, 6, 7 connected to the gas leak alarms 1, 4, 5, 8 that have detected the alarm state. If the alarm occurrence data that should have been received is not received again within 4 minutes from the previous reception, the other wireless devices 2, 3, 6, 7 that received the alarm occurrence data 4 minutes ago received the alarm release data. Similarly to the case, the other gas leak alarm devices 1, 4, 5, 8 other than the gas leak alarm devices 1, 4, 5, 8 connected to the radio devices 2, 3, 6, 7 of the alarm generation data transmission source. If the alarm state is not detected at 8, the output of the alarm notification signal to the gas leak alarms 1, 4, 5, 8 connected to itself is terminated, and the connected gas leak alarms 1, 4, 5 are connected. , 8 occurred in other gas leak alarms 1, 4, 5, 8 Informing operation using the voice notification function of the alarm state is terminated.

  Incidentally, the transmission function of the wireless devices 2, 3, 6 and 7 in this embodiment is a signal that triggers the transmission (for example, an alarm from the gas leak alarms 1, 4, 5, and 8 that triggers transmission of alarm generation data). Signal) is input to the microcomputer μCOM.

  In addition, the reception function of the wireless devices 2, 3, 6, and 7 in this embodiment is turned on for a short time every fixed period, and at that time, received data (for example, from other wireless devices 2, 3, 6, and 7) If alarm generation data or alarm release data) is not detected, it is immediately turned off, and the ON state is continued until reception is completed only when reception data is detected.

  Further, in the wireless devices 2, 3, 6, and 7 of the present embodiment, the port Pio that connects the gas leak alarms 1, 4, 5, and 8 is an input / output port. , 4, 5, 8, the input interface (not shown) is set in the sleep state, and the signal output from the gas leak alarms 1, 4, 5, 8 is output (not shown). The interface is put into a sleep state.

  By operating the transmission function and the reception function of the wireless devices 2, 3, 6, and 7 and the input / output interface associated with the port Pio as described above, the wireless devices 2, 3, 6, and 7 are used as power sources. Consumption of a battery (not shown) can be suppressed as much as possible.

  As described above, according to the automatic linkage system of the present embodiment, the alarm signal output starts from the radio devices 2, 3, 6, and 7 to which the gas leak alarm devices 1, 4, 5, and 8 that output the alarm signal are connected. The alarm generation data is output every 3 minutes from the hour, and in the other wireless devices 2, 3, 6, and 7 that have received the alarm generation data, the next alarm generation data is received even if 4 minutes have elapsed since the reception of the previous alarm generation data. If not received, the same processing is performed as when alarm release data is received from the radio devices 2, 3, 6 and 7 that are the transmission sources of the alarm occurrence data.

  For this reason, a failure occurs in the communication state between the respective radio devices 2, 3, 6, and 7, and the radio devices 2, 3 to which the gas leak alarm devices 1, 4, 5, and 8 that have finished outputting the alarm signal are connected. , 6 and 7 even when the alarm release data cannot be received, the alarm state notification operation for the gas leak alarms 1, 4, 5 and 8 connected to the other wireless devices 2, 3, 6 and 7 Can be prevented from continuing unnecessarily.

  In this embodiment, the case where there are four sets of gas leak alarms 1, 4, 5, and 8 and wireless devices 2, 3, 6, and 7 connected thereto has been described. And when there are two or more sets of wireless devices connected thereto, the present invention can be widely applied.

  Moreover, the alarm device connected to the radio devices 2, 3, 6, and 7 to which the present invention is applied is not limited to the gas leak gas leak alarm device 1, 4, 5, and 8 shown in the above-described embodiment, For example, an alarm signal that is output when an alarm condition occurs, such as a fire alarm or a window sensor, or a malfunction of an internal circuit or sensor is detected periodically and the alarm signal is transmitted to a wireless device (external). It may be an alarm device that outputs.

  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.
