Description

  The present invention relates to alternative systems.

  Conventionally, there has been known a disaster prevention receiver that performs a disaster prevention monitoring operation (for example, an operation for monitoring the occurrence of a fire and an operation for alarming a fire) that is an operation related to a fire in a monitoring area (Patent Document 1). In this disaster prevention receiver, the disaster prevention program is recorded in its own recording unit, and the disaster prevention monitoring operation is performed by executing the recorded disaster prevention program.

JP 2006-155291 A

  By the way, in the disaster prevention receiver of patent document 1, the update operation | work of the disaster prevention program currently recorded on the disaster prevention receiver was performed regularly for the purpose of functional enhancement regarding a disaster prevention monitoring operation, etc. However, when this update operation is performed, since it is generally necessary to temporarily stop the disaster prevention monitoring operation, the disaster prevention monitoring operation may not be performed during the update operation.

  The present invention has been made in view of the above problems, and an object thereof is to improve the reliability of disaster prevention for a monitoring area.

  In order to solve the above-described problems and achieve the object, the alternative system according to claim 1 performs the monitoring operation when updating information of a disaster prevention device that performs a monitoring operation that is an operation related to monitoring of a monitoring area. The disaster prevention device is a disaster prevention monitoring operation information storage unit that stores information for disaster prevention monitoring operation that is information for performing the monitoring operation, and the disaster prevention monitoring operation storage unit stores the disaster prevention monitoring information. The disaster prevention side operation means for performing the monitoring operation using the disaster prevention side monitoring operation information, and the alternative system is stored in the disaster prevention side monitoring operation information storage means Alternative-side monitoring operation information storage means for storing alternative-side monitoring operation information, which is information corresponding to the monitoring-operation information, and the disaster prevention-side monitoring operation information stored in the disaster prevention-side monitoring operation information storage means An alternative side detection means for detecting whether the update is in progress, and the alternative side monitoring operation information storage means when the alternative side detection means detects that the disaster prevention side monitoring operation information is being updated Using the substitute side monitoring operation information stored therein, the substitute side operation means performing the monitoring operation in place of the disaster prevention side operation means.

  Further, the alternative system according to claim 2 is the alternative system according to claim 1, wherein the alternative system is a function of a part of the disaster prevention device in which the monitoring operation is replaced by the alternative operation means. It is built into the disaster prevention device.

  Further, the alternative system according to claim 3 is the alternative system according to claim 1, wherein the alternative system is separate from the disaster prevention device in which the monitoring operation is replaced by the alternative side operation means. is there.

  The alternative system according to claim 4 is the alternative system according to claim 3, wherein the disaster prevention device performs at least a first monitoring operation which is an operation for monitoring at least a part of the monitoring area. The first receiver, the disaster prevention monitoring operation information storage means of the first receiver stores information for performing the first monitoring operation as the disaster prevention monitoring operation information, The disaster prevention side operation means of the first receiver uses the disaster prevention side monitoring operation information stored in the disaster prevention side monitoring operation information storage means of the first receiver. The alternative system is a second receiver that performs at least a second monitoring operation that is an operation of monitoring at least another part of the monitoring region, and the second receiver performs the second monitoring operation. For alternative side monitoring operation The information storage means stores information corresponding to the information for performing the first monitoring operation as information for the alternative side monitoring operation, and the alternative side detection means of the second receiver Detecting whether the disaster prevention monitoring operation information stored in the disaster prevention monitoring operation information storage means of the receiver is being updated, and the alternative operation means of the second receiver, When the alternative side detection unit of the second receiver detects that the disaster prevention side monitoring operation information is being updated, the alternative side monitoring operation information storage unit of the second receiver stores the information. The first monitoring operation is performed in place of the disaster prevention operation means of the first receiver using the information for the replacement monitoring operation performed.

  According to the alternative system of claim 1, when it is detected that the information for disaster prevention side monitoring operation is being updated, the alternative side operation means performs the monitoring operation in place of the disaster prevention side operation means, For example, even when the disaster prevention monitoring operation information is being updated, the monitoring operation can be performed using the alternative monitoring operation information that is different from the disaster prevention monitoring operation information to be updated. Therefore, the monitoring area can be constantly monitored, and the reliability of disaster prevention for the monitoring area can be improved.

  According to the alternative system described in claim 2, the monitoring system is constantly monitored using, for example, a single device by incorporating the alternative system as a part of the function of the disaster prevention device whose monitoring operation is replaced. Therefore, it is not necessary to install a dedicated device or the like for substituting for the monitoring operation, and the space in which the disaster prevention device is installed can be saved. In addition, for example, since communication with the above-described dedicated device is not required to replace the monitoring operation, a communication network is not necessary, and thus the cost for replacing the monitoring operation (for example, laying cost, or Operational costs) can be reduced.

  According to the alternative system of the third aspect, the alternative system can be provided at a position separated from the disaster prevention device, for example, by being separate from the disaster prevention device whose monitoring operation is replaced. Therefore, it is possible to prevent an alternate system from being operated by an operator by mistake while updating the information for monitoring operation on the disaster prevention side, and to prevent the alternate system from malfunctioning due to an incorrect operation. Can do.

  According to the alternative system of claim 4, the disaster prevention device is the first receiver and the alternative system is the second receiver, so that, for example, the function of the alternative system is realized using an existing device. Therefore, it is not necessary to install a new device, and the monitoring operation can be replaced at a low cost.

(Configuration-Disaster prevention system-Receiver-Display unit)
The display unit 33 is a display unit that displays various types of information. Although the specific type and configuration of the display unit 33 are arbitrary, for example, the display unit 33 can be configured to include a known flat panel display such as a liquid crystal display or an organic EL display.

(Configuration-Disaster prevention system-Receiver-Sound section)
The acoustic unit 34 is an acoustic unit that outputs an alarm sound. Although the specific kind and structure of the acoustic part 34 are arbitrary, for example, it can comprise with a well-known speaker etc.

(Configuration-Disaster prevention system-Receiver-Recording unit)
The recording unit 35 is a recording unit that records a program and various data necessary for the operation of the receiver 3, is a disaster prevention side monitoring operation information storage unit, and is an alternative side monitoring operation information storage unit. Yes, for example, using a known recording device. As this known recording device, for example, a hard disk as an external recording device, a magnetic recording medium such as a magnetic disk, an optical recording medium such as a DVD or a Blu-ray disc, or a flash, ROM, USB memory, or SD card. Such an electric recording medium or any other arbitrary recording medium can be used (the same applies to recording units of other apparatuses described in this specification).

  In the recording unit 35, for example, a receiver ID, normal information, update information, and an update flag are stored.

  Here, the “receiver ID” is information for uniquely identifying the receiver 3. And about such receiver ID, "IDc1" shall be input and stored via the communication part 31 or the operation part 32. FIG.

  The “normal information” is information for operating the receiver 3 at normal time when the normal information itself is not updated. For example, the normal information is information including normal monitoring information and normal additional information. is there. “Normal monitoring information” is information for disaster prevention side monitoring operation that is information for performing a monitoring operation, and is information including, for example, a normal disaster prevention program and device information. The “ordinary disaster prevention program” is a program for performing a monitoring operation, and is a program for performing a normal monitoring operation process described later. “Device information” is information for performing a monitoring operation, and is information for specifying a device associated with the receiver 3. FIG. 2 is a diagram illustrating device information. As shown in FIG. 2, the device information is configured by associating an item “receiver ID”, an item “sensor ID”, an item “speaker ID”, and information corresponding to each item. Yes. Here, the information corresponding to the item “receiver ID” is the above-described receiver ID (“IDc1” in FIG. 2). The information corresponding to the item “sensor ID” is the sensor ID described above (“IDa1” in FIG. 2). Further, the information corresponding to the “speaker ID” is the above-described speaker ID (“IDb1” in FIG. 2) The “normal additional information” is information different from the information for monitoring operation on the disaster prevention side. , A prediction program for performing a prediction operation that is an operation for predicting replacement time of components (for example, a spare battery or a display) of the receiver 3, or a test operation that is an operation for performing an automatic test on the sensor 1. It is information including a test program for performing. Such normal information is input and stored through the communication unit 31 or the operation unit 32, and then, at least a part of the information included in the normal information is corrected or new. In order to add a function or the like, it is assumed that the entire normal information is updated by performing a known update operation in units of the entire normal information at the timing of the new version release.

  Returning to FIG. 1, “update information” is information for operating the receiver 3 at the time of update, which is the time when normal information is updated, for example, information including update monitoring information. . The “update monitoring information” is information on the alternative side monitoring operation that is information corresponding to the normal monitoring information of the normal information stored in the recording unit 35, and includes, for example, the update disaster prevention program and the device information. It is information to include. The “information corresponding to the normal monitoring information” is information that functions in the same manner as the normal monitoring information, and is information for performing a monitoring operation, for example. The “update disaster prevention program” is a program for performing a monitoring operation, and is a program for performing an update monitoring operation process to be described later, and has a content corresponding to the above-described normal disaster prevention program. The “device information” is common to the device information in the normal monitoring information of the normal information. Such update information is input and stored via the communication unit 31 or the operation unit 32.

  The “update flag” is information notified about the update of the normal information, and specifically is information indicating whether or not the normal information is being updated. Then, for this update flag, the control unit 36 stores “update in progress” when a known update operation is being performed, and stores “not updated” when the update operation is not being performed. It shall be.

(Configuration-Disaster prevention system-Receiver-Control unit)
The control unit 36 is a control unit that controls the receiver 3, and specifically, a CPU, various programs that are interpreted and executed on the CPU (a basic control program such as an OS, and a specific function that is activated on the OS And an internal memory such as a RAM for storing the program and various data. In particular, the control program according to the embodiment is substantially installed in the receiver 3 via an arbitrary recording medium or network, so that each unit of the control unit 36 is substantially configured (others described in this specification). The same applies to the control unit of the apparatus).

The control unit 36 includes a disaster prevention side operation unit 361, an alternative side detection unit 362, and an alternative side operation unit 363 in terms of functional concept. The disaster prevention operation unit 361 is a disaster prevention operation unit that performs monitoring operations (for example, an abnormality determination operation, an alarm operation, and a recovery operation) using the normal monitoring information of the normal information stored in the recording unit 35. . The alternative side detection unit 362 is an alternative side detection unit that detects whether or not the normal monitoring information of the normal information stored in the recording unit 35 is being updated. When the alternative side detection unit 362 detects that the normal monitoring information of the normal information is being updated, the alternative side operation unit 363 uses the update monitoring information of the update information stored in the recording unit 35. This is alternative side operation means for performing the monitoring operation in place of the disaster prevention side operation unit 361. The processing performed by each unit of the control unit 36 will be described later. The “recording unit 35”, “alternative side detection unit 362”, and “alternative side operation unit 363” correspond to the alternative system.
It corresponds to.

(processing)
Next, processing executed by the disaster prevention system 100 configured as described above will be described. Specifically, normal monitoring operation processing, update monitoring operation processing, and monitoring operation control processing will be described.

(Processing-Normal monitoring operation processing)
FIG. 3 is a flowchart of the normal monitoring operation process (in the following description of each process, step is abbreviated as “S”). The “normal monitoring operation process” is a process for performing a monitoring operation (for example, an abnormality determination operation, an alarm operation, and a recovery operation). Specifically, the disaster prevention operation unit 361 performs normal operation of the recording unit 35 in FIG. This is a process performed using the normal disaster prevention program for equipment information and device information. For example, the same process as the conventional process can be performed, but here, the process illustrated in FIG. 3 will be described as an example. To do. The normal monitoring operation process is executed during a monitoring operation control process to be described later, and thereafter repeatedly executed until the execution is terminated in the monitoring operation control process.

  First, as shown in FIG. 3, in SA1, the disaster prevention operation unit 361 determines whether or not the sensor 1 has issued a notification (that is, performs an abnormality determination operation). Although a specific determination method is arbitrary, for example, when the sensor 1 of FIG. 1 determines the occurrence of a fire, it is configured to transmit a notification signal including “IDa1” that is its own sensor ID. It is assumed that the determination is made based on the alarm signal from the sensor 1. Specifically, the disaster prevention operation unit 361 monitors the communication unit 31 and makes a determination based on whether or not a notification signal has been received. If no notification signal has been received, it is determined that no notification has been issued (NO in SA1), and SA1 is repeatedly executed until it is determined that a notification has been issued. Further, when the alarm signal is received, it is determined that the alarm has been issued (YES in SA1), and the process proceeds to SA2. Here, for example, when a notification signal including “IDa1” is received, it is determined that the notification has been issued.

  Returning to FIG. 3, in SA2, the disaster prevention operation unit 361 performs an alarm operation. Although a specific warning method is arbitrary, for example, with reference to the device information of the normal information in the recording unit 35 in FIG. 1, the alarm method is associated with the sensor ID included in the alert signal received at SA1. The speaker ID is identified, and the alarm operation is performed by starting the repeated sound output of the alarm sound to the monitoring area via the speaker device in the hall identified by the identified speaker ID. Here, for example, after specifying “IDb1” in FIG. 2 as the speaker ID, a repeated voice output of an alarm message such as “Sensor has issued” is performed via the speaker device 2 in FIG. Start and perform alarm action.

  Returning to FIG. 3, in SA3, the disaster prevention operation unit 361 determines whether or not to perform a recovery operation. Although a specific determination method is arbitrary, for example, the determination is made based on whether or not a known recovery operation is accepted via the operation unit 32 of FIG. If no recovery operation has been received, it is determined that the operation is not recovered (NO in SA3), and SA3 is repeatedly executed until it is determined that the operation is recovered. If a recovery operation is received, it is determined that the operation will be recovered (YES in SA3), and the process proceeds to SA4. Here, for example, when a recovery operation is received by a user operating through the operation unit 32, it is determined that the user is to be recovered.

  Returning to FIG. 3, in SA4, the disaster prevention operation unit 361 performs a recovery operation. Although a specific recovery operation method is arbitrary, the alarm sound is stopped, and a recovery signal that is a signal for recovering the alarmed sensor 1 is transmitted. Here, for example, the alarm sound from the in-speaker speaker device 2 that started the repeated output at SA2 is stopped, and the sensor ID “IDa1” included in the alarm signal received at SA1 is acquired. The sensor 1 is restored by transmitting a restoration signal including the acquired “IDa1”. This completes one flow of the normal monitoring operation process. In addition, after this one-time flow is completed, the normal monitoring operation process is repeatedly executed until the execution is ended in the monitoring operation control process as described above.

(Processing-Update monitoring operation processing)
The “update monitoring operation process” is a process for performing a monitoring operation (for example, an abnormality determination operation, an alarm operation, and a recovery operation). Specifically, the alternative operation unit 363 updates the recording unit 35 in FIG. This is a process performed using the disaster prevention program for updating information and the device information, for example, a process similar to the normal monitoring operation process. This update monitoring operation process is executed during the monitoring operation control process, which will be described later, similarly to the normal monitoring operation, and thereafter repeatedly executed until the execution is terminated in the monitoring operation control process. It is. Note that this update monitoring operation process is the same as the normal monitoring operation process except for the execution subject of each step and the information to be used, etc., so the reference numerals “SB1” to “SB4” are attached to FIG. Only the outline will be described with reference to FIG.

  As illustrated in FIG. 3, the alternative side operation unit 363 performs SB1 to SB4 in the same manner as SA1 to SA4. This completes one flow of the update monitoring operation process. After this one-time flow is completed, the update monitoring operation process is repeatedly executed until the execution is ended in the monitoring operation control process as described above.

(Processing-Monitoring operation control processing)
FIG. 4 is a flowchart of the monitoring operation control process. The “monitoring operation control process” is a process for controlling a monitoring operation (for example, an abnormality determination operation, an alarm operation, and a recovery operation). Specifically, it is a process executed by the receiver 3 and is normally monitored. This is a process for controlling the start or end of the operation process or the update monitoring operation process. The timing of executing the monitoring operation control process is arbitrary timing. For example, the monitoring operation control process is executed after turning on the power of each device of the disaster prevention system 100 and repeatedly executed after the activation. It will be explained after it is started. Here, for example, a case where an update operation for updating the normal information in the recording unit 35 in FIG. 1 for adding a new function will be described as an example.

  First, as shown in FIG. 4, in SC1, the disaster prevention operation unit 361 starts the normal monitoring operation process. Specifically, the SA1 to SA4 in FIG. 3 are repeatedly executed using the normal disaster prevention program and the device information in the normal information in the recording unit 35 in FIG.

  Returning to FIG. 4, in SC2, the alternative side detection unit 362 determines whether or not the update of the normal information in the recording unit 35 of FIG. 1 has started. Although a specific determination method is arbitrary, for example, the update flag of the recording unit 35 is referred to and the determination is made based on the referred update flag. When the update flag is “not updated”, it is determined that the normal information is not being updated after detecting that the normal information is not being updated (NO in SC2). SC2 is repeatedly executed until it is determined that the normal information update has started. If the update flag is “update in progress”, it is determined that the normal information is being updated after detecting that the normal information is being updated (YES in SC2). Move to SC3. Here, for example, a maintenance person visits the receiver 3 and performs a predetermined operation via the operation unit 32 after inputting update information to the receiver 3 using a predetermined device (for example, a memory stick). Thus, when the update work is started to add a new function, it is determined that the update of the normal information is started.

  Returning to FIG. 4, in SC3, the disaster prevention operation unit 361 ends the normal monitoring operation process. Specifically, the normal monitoring operation process is terminated so that SA1 to SA4 in FIG. 3 are not repeatedly executed. Here, since the normal information in the recording unit 35 in FIG. 1 is being updated and cannot be used, the control unit 36 cannot use the prediction program and the test program in the normal additional information of the normal information. Thus, the prediction operation and the test operation cannot be performed.

  Returning to FIG. 4, in SC4, the alternative side operation unit 363 starts the update monitoring operation process. Specifically, the SB1 to SB4 of FIG. 3 are repeatedly started using the update disaster prevention program and the device information of the update information of the recording unit 35 of FIG.

  Returning to FIG. 4, in SC5, the alternative side detection unit 362 determines whether or not the update of the normal information in the recording unit 35 of FIG. Although a specific determination method is arbitrary, for example, similarly to the case of SC2, the update flag of the recording unit 35 is referred to, and the determination is made based on the referred update flag. If the update flag is “update in progress”, it is determined that the update of the normal information is not completed after detecting that the normal information is being updated (NO in SC5). The SC5 is repeatedly executed until it is determined that the normal information update has been completed. If the update flag is “not updated”, it is determined that the normal information has not been updated, and it is determined that the normal information has been updated (YES in SC5). Transition. Here, for example, when the update work for adding a new function is completed, it is determined that the update of the normal information is completed.

  Returning to FIG. 4, in SC6, the alternative side operation unit 363 ends the update monitoring operation process. Specifically, the update monitoring operation process is terminated so that the repeated execution of SB1 to SB4 in FIG. 3 is not performed.

  Returning to FIG. 4, in SC7, the disaster prevention operation unit 361 starts the normal monitoring operation process. Specifically, similarly to SC1, the repeated execution of SA1 to SA4 in FIG. 3 is started using the normal disaster prevention program for normal information and device information in the recording unit 35 in FIG. Here, since the normal information in the recording unit 35 in FIG. 1 can be used without being updated, the prediction program and the test program in the normal additional information of the normal information can be used. The operation and test operation can be executed. Thus, the monitoring operation control process ends. After this one-time flow is completed, the monitoring operation control process is repeatedly executed as described above. However, in SC1 when repeatedly executed, the process is the same as SC7 in the previous flow. Therefore, it may be omitted.

(About processing examples)
With the above processing, for example, when the normal information of the recording unit 35 in FIG. 1 has not been updated, the monitoring operation in the normal monitoring operation process by the disaster prevention side operation unit 361, the prediction operation by the control unit 36, and A test operation will be performed. Further, for example, when the normal information of the recording unit 35 in FIG. 1 is updated, the prediction operation and the test operation by the control unit 36 are not performed, but the update monitoring operation process by the alternative side operation unit 363 is performed. A monitoring operation will be performed. In other words, it is possible to prevent the monitoring area from being constantly monitored and not monitoring regardless of whether or not the normal information in the recording unit 35 has been updated, so that it is possible to maintain a high level of disaster prevention in the monitoring area. It becomes.

(Effect of Embodiment 1)
As described above, according to the present embodiment, when it is detected that the normal information is being updated, the substitute side operation unit 363 performs the monitoring operation in place of the disaster prevention side operation unit 361, for example, Even when the normal information is being updated, the monitoring operation can be performed using the update information that is different from the normal information to be updated. It is possible to improve the reliability of disaster prevention for the monitoring area.

  In addition, since the alternative system (for example, the recording unit 35, the alternative side detection unit 362, and the alternative side operation unit 363) is incorporated as a part of the function of the receiver 3 that is replaced with the monitoring operation, for example, Since the monitoring area can be constantly monitored using one apparatus, it is not necessary to install a dedicated apparatus or the like for substituting the monitoring operation, and the area where the receiver 3 is installed can be saved. . In addition, for example, since communication with the above-described dedicated device is not required to replace the monitoring operation, a communication network is not necessary, and thus the cost for replacing the monitoring operation (for example, laying cost, or Operational costs) can be reduced.

(Embodiment 2)
Next, a second embodiment will be described. In this embodiment, a case where the alternative system is configured as a separate body from the disaster prevention apparatus whose monitoring operation is replaced will be described. Specifically, a case will be described in which each receiver substitutes for a monitoring operation of a receiver other than itself in a system in which a plurality of receivers are distributed in a monitoring target building.

(Constitution)
First, the configuration of the disaster prevention system according to the present embodiment will be described.

(processing)
Next, processing executed by the disaster prevention system 400 configured as described above will be described. Specifically, the self-monitoring operation process, the other person monitoring operation process, the self-monitoring operation control process, and the other person monitoring operation control process will be described. Note that all of these processes can be executed in the same manner by both the receiver 6 and the receiver 9, but here, for convenience of explanation, the case where the receiver 6 executes these processes. explain.

(Processing-Self-monitoring operation processing)
The “self-monitoring operation process” is a process for performing a monitoring operation (for example, an abnormality determination operation, an alarm operation, and a recovery operation) for the self-monitoring region. This process is performed for the first monitoring area by using the self-use disaster prevention program for the self-use information and the self-use device information in the recording unit 65, for example, the same process as the normal monitoring operation process of the first embodiment. This self-monitoring operation process is executed during a self-monitoring operation control process to be described later, and thereafter repeatedly executed until the execution is terminated in the self-monitoring operation control process. Since this self-monitoring operation process is the same as the normal monitoring operation process of the first embodiment except for the execution subject of each step and the information to be used, reference numerals “SD1” to “SD4” in FIG. And will be described with reference to FIG.

  First, as shown in FIG. 3, in SD1, the disaster prevention operation unit 661 determines whether or not the sensor 4 has issued a notification (that is, performs an abnormality determination operation). Although the specific determination method is arbitrary, for example, it is assumed that it is the same as SA1 of the first embodiment, that is, when the sensor 4 of FIG. It is assumed that a notification signal including “IDa11” is configured to be transmitted, and the determination is based on the notification signal from the sensor 4. Specifically, the disaster prevention operation unit 661 monitors the communication unit 61 and makes a determination based on whether a notification signal is received. If no notification signal is received, it is determined that no notification has been issued (NO in SD1), and SD1 is repeatedly executed until it is determined that a notification has been issued. Further, when a notification signal is received, it is determined that a notification has been issued (YES in SD1), and the process proceeds to SD2. Here, for example, when a report signal including “IDa11” is received, it is determined that a report is issued.

  Returning to FIG. 3, in SD2, the disaster prevention operation unit 661 performs an alarm operation. Although the specific alarm method is arbitrary, for example, it is assumed that it is the same as SA2 in the first embodiment, that is, with reference to the self-device information of the self-use information in the recording unit 35 in FIG. The speaker ID associated with the sensor ID included in the received alert signal is specified, and the alarm sound is repeatedly output to the monitoring area through the in-speaker speaker device identified by the specified speaker ID. To start alarm action. Here, for example, after specifying “IDb11” in FIG. 6 as the speaker ID, repeated voice output of an alarm message such as “Sensor has issued” is performed through the speaker device 5 in FIG. Start and perform alarm action.

  Returning to FIG. 3, in SD <b> 3, the disaster prevention operation unit 661 determines whether to perform a recovery operation. Although the specific determination method is arbitrary, for example, it is assumed that it is the same as SA3 of the first embodiment, that is, the determination is based on whether or not a known restoration operation is accepted via the operation unit 62 of FIG. To do. If a recovery operation has not been received, it is determined that the operation is not recovered (NO in SD3), and SD3 is repeatedly executed until it is determined that the operation is recovered. If a recovery operation is accepted, it is determined that the operation will be recovered (YES in SD3), and the process proceeds to SD4. Here, for example, when a recovery operation is accepted by a user operating through the operation unit 62, it is determined that the recovery is to be performed.

  Returning to FIG. 3, in SD4, the disaster prevention operation unit 661 performs a recovery operation. Although a specific recovery operation method is arbitrary, for example, the same operation as SA4 of the first embodiment is performed, the alarm sound is stopped, and the recovery is a signal for recovering the sensor 4 that has issued the alarm. Send a signal. Here, for example, the alarm sound from the in-speaker speaker device 5 that started to output repeatedly at SD2 is stopped, and the sensor ID “IDa11” included in the alarm signal received at SD1 is acquired. The sensor 4 is restored by transmitting a restoration signal including the acquired “IDa11”. This completes one flow of the self-monitoring operation process. After this one-time flow is completed, the self-monitoring operation process is repeatedly executed until the execution is terminated in the self-monitoring operation control process as described above.

(Processing-others monitoring operation processing)
The “other person monitoring operation process” is a process for performing a monitoring operation (for example, an abnormality determination operation, an alarm operation, and a recovery operation) for the other person's monitoring area. 5 is a process to be performed on the second monitoring area using the disaster prevention program for the other person and the device information for the other person, and is similar to the normal monitoring operation process of the first embodiment, for example. It is processing. The other person monitoring operation process is executed during the other person monitoring action control process described later, and thereafter repeatedly executed until the execution is terminated in the other person monitoring action control process. . This other person monitoring operation process is the same as the normal monitoring operation process of the first embodiment except for the execution subject of each step, information to be used, and the like. Therefore, “SE1” to “SE4” in FIG. A description will be given with reference to FIG.

  First, as shown in FIG. 3, in SE1, the alternative side operation unit 663 determines whether or not the sensor 7 has issued a notification (that is, performs an abnormality determination operation). Although the specific determination method is arbitrary, for example, the first monitoring area side disaster prevention system 400A and the second monitoring area side disaster prevention system 400B are assumed to be the same as SD1 in view of being able to communicate with each other. That is, when the sensor 7 in FIG. 5 determines the occurrence of a fire, it is assumed that the sensor 7 is configured to transmit an alarm signal including “IDa21” which is its own sensor ID. The determination is made based on the notification signal. Specifically, the alternative operation unit 663 monitors the communication unit 61 and makes a determination based on whether or not a notification signal has been received. If no notification signal has been received, it is determined that no notification has been issued (NO in SE1), and SE1 is repeatedly executed until it is determined that a notification has been issued. Further, when a notification signal is received, it is determined that a notification has been issued (YES in SE1), and the process proceeds to SE2. Here, for example, when a notification signal including “IDa21” is received, it is determined that the notification has been issued.

  Returning to FIG. 3, in SE2, the alternative side operation unit 663 performs an alarm operation. Although the specific warning method is arbitrary, for example, the first monitoring area side disaster prevention system 400A and the second monitoring area side disaster prevention system 400B are assumed to be the same as SD2 in view of being able to communicate with each other. That is, the speaker ID associated with the sensor ID included in the notification signal received in SE1 is identified with reference to the other device information for the other information in the recording unit 35 of FIG. Then, through the speaker device in the hall identified by the specified speaker ID, repeated alarm sound output to the monitoring area is started and an alarm operation is performed. Here, for example, after specifying “IDb21” in FIG. 7 as the speaker ID, a repeated voice output of an alarm message such as “Sensor has issued” is performed via the speaker device 8 in FIG. Start and perform alarm action.

  Returning to FIG. 3, in SE3, the alternative side operation unit 663 determines whether or not to perform the recovery operation. Although a specific determination method is arbitrary, for example, it is assumed that it is the same as that of SD3, that is, a determination is made based on whether or not a known recovery operation is accepted via the operation unit 62 of FIG. If no recovery operation has been received, it is determined that the operation is not recovered (NO in SE3), and SE3 is repeatedly executed until it is determined that the operation is recovered. If a recovery operation is accepted, it is determined that the operation will be recovered (YES in SE3), and the process proceeds to SE4.

  Returning to FIG. 3, in SE4, the alternative side operation unit 663 performs a recovery operation. The specific recovery operation method is arbitrary, but it is assumed that the first monitoring area side disaster prevention system 400A and the second monitoring area side disaster prevention system 400B can communicate with each other in the same manner as SD4, That is, the alarm sound is stopped, and a restoration signal which is a signal for restoring the alarmed sensor 7 is transmitted. Here, for example, the alarm sound from the in-speaker speaker device 7 that started the repeated output in SE2 is stopped, and the sensor ID “IDa21” included in the alarm signal received in SE1 is acquired. Then, the sensor 7 is recovered by transmitting a recovery signal including the acquired “IDa21”. Thus, the one-time flow of the other person monitoring operation process is completed. After this one-time flow is completed, the other person monitoring operation process is repeatedly executed until the execution is ended in the other person monitoring operation control process as described above.

(Processing-Self-monitoring operation control processing)
FIG. 9 is a flowchart of the self-monitoring operation control process. The “self-monitoring operation control process” is a process for controlling a monitoring operation (for example, an abnormality determination operation, an alarm operation, and a recovery operation) for the self-monitoring area, and specifically, the receiver 6 that is itself. Is a process for controlling the start or end of the self-monitoring operation process and requesting the start or end of the other-person monitoring operation process by the receiver 9 as another party as necessary. The timing for executing this self-monitoring operation control process is arbitrary timing. For example, the self-monitoring operation control is assumed to be started after turning on the power of each device of the disaster prevention system 400 and repeatedly executed after the startup. A description will be given after the processing is started (the same applies to other person monitoring operation processing described later). Here, for example, a case where an update operation for updating the self-use information of the self-recording unit 65 in FIG. 5 for adding a new function will be described as an example.

  First, as shown in FIG. 9, in SF1, the disaster prevention operation unit 661 starts a self-monitoring operation process. Specifically, the execution of repetition of SD1 to SD4 in FIG. 3 is started using the self-use disaster prevention program of the self-use information and the self-use device information in the recording unit 65 in FIG.

  Returning to FIG. 9, in SF2, the control unit 66 determines whether or not the update of the self-use information of the self-recording unit 65 of FIG. 5 has started. Although the specific determination method is arbitrary, for example, referring to the flag information of the recording unit 65, referring to the update status information corresponding to “IDc11” that is the receiver ID of FIG. The determination is made based on the update state information. If the update status information is “not updated”, it is determined that the update of the self-use information is not started after detecting that the self-use information is not being updated (in SF2). NO), SF2 is repeatedly executed until it is determined that the update of the self-use information is started. If the update status information is “update in progress”, it is determined that the update of the self-use information is started after detecting that the self-use information is being updated (SF2 YES), the process proceeds to SF3. Here, for example, when an update operation is started to add a new function, it is determined that the update of the self-use information is started.

  Returning to FIG. 9, in SF3, the disaster prevention operation unit 661 ends the self-monitoring operation process. Specifically, the self-monitoring operation process is terminated so that the repeated execution of SD1 to SD4 in FIG. 3 is not performed. Here, since the self-use information of the recording unit 65 in FIG. 5 is being updated and cannot be used, the control unit 66 cannot use the prediction program and the test program in the self-addition information of the self-use information. Thus, the prediction operation and the test operation cannot be performed.

  Returning to FIG. 9, in SF4, the control unit 66 transmits a monitoring start request signal. Here, the “monitoring start request signal” is a signal for requesting the other person to start the other person monitoring operation process. Although a specific transmission method for SF4 is arbitrary, for example, a monitoring start request signal including “IDc11” that is the own receiver ID and “IDc21” that is the other party's receiver ID is generated and generated. The monitoring start request signal is transmitted to the receiver 9 as the other party via the communication unit 61 in FIG. On the other hand, the control unit 96 of the receiver 9 that is the other party receives a monitoring start request signal including “IDc21” that is its own receiver ID (for the receiver 9) via the communication unit 91. After identifying “IDc11” which is the receiver ID of the other party (for the receiver 9) in the received monitoring start request signal, the update state information corresponding to the identified “IDc11” in the flag information of the recording unit 95 "Update in progress" is stored and updated.

  Returning to FIG. 9, in SF5, the control unit 66 determines whether or not the update of the self-use information of the recording unit 65 of FIG. Although the specific determination method is arbitrary, for example, referring to the flag information of the recording unit 65, referring to the update status information corresponding to “IDc11” that is the receiver ID of FIG. The determination is made based on the update state information. When the update status information is “update in progress”, it is determined that the update of the self-use information is not completed after detecting that the self-use information is being updated (SF5). NO), and SF5 is repeatedly executed until it is determined that the update of the self-use information is completed. If the update status information is “not updated”, it is determined that the update of the self-use information is completed after detecting that the self-use information is not being updated (YES in SF5). To SF6. Here, for example, when the update work for adding a new function is completed, it is determined that the update of the self-use information is completed.

  Returning to FIG. 9, in SF6, the disaster prevention operation unit 661 starts the self-monitoring operation process. Specifically, similarly to SF1, the execution of repetition of SD1 to SD4 in FIG. 3 is started using the self-use disaster prevention program for self-use information and the self-use device information in the recording unit 65 in FIG. Here, since the self-use information of the recording unit 65 in FIG. 5 can be used without being updated, the prediction program and the test program in the self-addition information of the self-use information can be used. The operation and test operation can be executed.

  Returning to FIG. 9, in SF7, the control unit 66 transmits a monitoring end request signal. Here, the “monitoring end request signal” is a signal for requesting the other party to end the other person monitoring operation process. Although a specific transmission method for SF7 is arbitrary, for example, in the same manner as SF4, a monitoring end request signal including “IDc11” that is its own receiver ID and “IDc21” that is the other party's receiver ID And the generated monitoring end request signal is transmitted to the receiver 9 as the other party via the communication unit 61 in FIG. On the other hand, the control unit 96 of the receiver 9 which is the other party receives the monitoring end request signal including “IDc21” which is its receiver ID (for the receiver 9) via the communication unit 91. Then, after specifying “IDc11” which is the receiver ID of the other party (for the receiver 9) in the received monitoring end request signal, the update state information corresponding to the specified “IDc11” in the flag information of the recording unit 95 "Update not performed" is stored and updated. This completes the self-monitoring operation control process.

(Processing-Other person monitoring operation control processing)
FIG. 10 is a flowchart of the other person monitoring operation control process. The “other person monitoring operation control process” is a process for controlling a monitoring operation (for example, an abnormality determination operation, an alarm operation, and a recovery operation) for the other person's monitoring area. This is a process in which the machine 6 controls the start or end of the other person's monitoring operation process. Here, for example, a case where update work for updating the self-use information of the recording unit 95 of the receiver 9 which is another of FIG.

  First, as shown in FIG. 10, in SG1, the alternative side detection unit 662 determines whether or not the update of the self-use information of the recording unit 95 of the receiver 9, which is the other party of FIG. Although the specific determination method is arbitrary, for example, referring to the flag information of the recording unit 65, referring to the update status information corresponding to “IDc21” that is the receiver ID of the other person in FIG. The determination is made based on the updated status information. When the update status information is “not updated”, it is determined that the update of the other person's own information is not started after detecting that the own information is not being updated (SG1 NO), SG2 is repeatedly executed until it is determined that the update of the other person's own information has started. If the update status information is “update in progress”, it is determined that the update of the other person's self-use information is started after detecting that the self-use information is being updated (SG1). YES), the process proceeds to SG2. Here, for example, when an update operation is started in the receiver 9 due to the addition of a new function, it is determined that the update of the other person's own information has been started.

  Returning to FIG. 10, in SG2, the alternative side operation unit 663 starts the other person monitoring operation process. Specifically, the execution of SE <b> 1 to SE <b> 4 in FIG. 3 is started using the disaster prevention program for the other person and the equipment information for the other person in the recording unit 65 in FIG. 5.

  Returning to FIG. 10, in SG3, the alternative side detection unit 662 determines whether or not the update of the self-use information of the recording unit 95 of the receiver 9 which is the other of FIG. Although the specific determination method is arbitrary, for example, referring to the flag information of the recording unit 65, referring to the update status information corresponding to “IDc21” that is the receiver ID of the other person in FIG. The determination is made based on the updated status information. When the update status information is “update in progress”, it is determined that the update of the other person's self-use information has not been completed after detecting that the self-use information is being updated ( SG3 is repeatedly executed until it is determined that the update of the other person's own information has been completed. If the update status information is “not updated”, it is determined that the update of the other person's own information has been completed after detecting that the own information is not being updated (YES in SG3). ), Move to SG4. Here, for example, when the update operation at the receiver 9 is completed, it is determined that the update of the other person's own information has been completed.

  Returning to FIG. 10, in SG4, the alternative side operation unit 663 terminates the other person monitoring operation process. Specifically, the other person monitoring operation process is terminated so that the repeated execution of SE1 to SE4 in FIG. 3 is not performed. This completes the other person's monitoring operation control process.

(About processing examples)
Regarding the above processing, a processing example by the receiver 6 and the receiver 9 of FIG. 5 will be described. As described above, each of the receiver 6 and the receiver 9 executes each process, and in particular, the self-monitoring operation control process and the other-person monitoring operation control process are performed in parallel. Here, for example, the self-monitoring operation control process performed by the receiver 6 and the other person monitoring operation control process performed by the receiver 9 will be mainly described.

  FIG. 11 is a flowchart illustrating a processing example of the self-monitoring operation control process and the other-person monitoring operation control process. In FIG. 11, the self-monitoring operation control process by the receiver 6 is indicated by reference signs “SH1” to “SH7”, and the other person monitoring operation control process by the receiver 9 is indicated by reference signs “SI1” to “SI1”. SI4 ". Since the details of each process are as described above, for example, after the receiver 6 starts the self-monitoring operation process, the self-information update operation of the receiver 6 in FIG. 5 is performed to add a new function. After starting, after an elapse of a predetermined time (for example, 1 to 2 hours, etc.), an example of processing in the case of ending the updating work is described only with an outline while referring to each processing of FIG. 9 or FIG. explain. Further, since the processing entity on the receiver 6 side has been specifically shown and described above, only the processing entity on the receiver 9 side will be specifically shown and described.

  As shown in FIG. 11, first, the receiver 6 starts a self-monitoring operation (SH1, SF1 in FIG. 9). Thereafter, when the update operation of the self-use information of the receiver 6 in FIG. 5 is started, the receiver 6 determines that the update of the self-use information is started (SH2, YES in SF2 in FIG. 9). ) After the self-monitoring operation process is completed (SH3, SF3 in FIG. 9), a monitoring start request signal is transmitted (SH4, SF4 in FIG. 9). On the other hand, after that, the alternative side detection unit 962 of the receiver 9 detects that the self-use information of the receiver 6 is being updated and determines that the update of the self-use information of the other party has started. (SI1, YES in SG1 in FIG. 10). Then, the alternative operation unit 963 of the receiver 9 starts the other person monitoring operation process (SI2, SG2 in FIG. 10). Thereafter, when the update operation of the self-use information of the receiver 6 is completed, the receiver 6 determines that the update of the self-use information is completed (SH5, YES in SF5 of FIG. 9), and self-monitoring. After the operation process is started (SH6, SF6 in FIG. 9), a monitoring end request signal is transmitted (SH7, SF7 in FIG. 9). On the other hand, after that, the alternative side detection unit 962 of the receiver 9 detects that the self information of the receiver 6 is not being updated, and determines that the update of the self information of the other party has been completed ( SI3, YES in SG3 in FIG. Then, the alternative side operation unit 963 of the receiver 9 ends the other person monitoring operation process (SI4, SG4 in FIG. 10).

  Thus, for the first monitoring area, for example, when the self-information of the receiver 6 in FIG. 5 is not updated, the monitoring operation by the self-monitoring operation process of the receiver 6 and the prediction operation and test are performed. On the other hand, for example, when the self-use information of the receiver 6 is updated, the prediction operation and the test operation are not performed, but monitoring by the other person monitoring operation process of the receiver 9 is performed. Operation will be performed. Although the second monitoring area is not specifically illustrated, for example, when the self-information of the receiver 9 in FIG. 5 is not updated, monitoring by the self-monitoring operation process of the receiver 9 is performed. For example, when the self-information of the receiver 9 is updated, the prediction operation and the test operation are not performed, but the receiver 6 The monitoring operation by the other person monitoring operation process is performed. As described above, in the first monitoring area and the second monitoring area, regardless of whether the self-use information of the receiver 6 and the receiver 9 has been updated, the monitoring operation is always performed and no monitoring is prevented. Therefore, it is possible to maintain the disaster prevention performance of the entire monitoring area at a high level.

(Effect of Embodiment 2)
As described above, according to the present embodiment, an alternative system (for example, the recording unit 95, the alternative side detection unit 962, and the alternative side operation unit 963 of the receiver 9) replaces the monitoring operation with a disaster prevention device (for example, reception). By being separate from the machine 6), for example, an alternative system (for example, the receiver 9) can be provided at a position away from the disaster prevention device (for example, the receiver 6). It is possible to prevent an operator from operating the substitute system (for example, the receiver 9) by mistake during the update operation of the self-use information, and the substitute system (for example, the receiver 9) is erroneously operated by the incorrect operation. It can prevent operating.

  In addition, since the disaster prevention device is the first receiver (for example, the receiver 6) and the alternative system is the second receiver (for example, the receiver 9), for example, the alternative system using an existing device. Therefore, it is not necessary to install a new device, and the monitoring operation can be replaced at low cost and low cost.

For example, at least one of the operations exemplified in the definition of the monitoring operation, or a known monitoring operation not specifically exemplified may be performed.

(About alternative system)
In the first embodiment, the case where the update information is stored in the receiver 3 and the alternative side detection unit 362 and the alternative side operation unit 363 are provided in the receiver 3 has been described. However, the present invention is not limited to this. For example, a replacement device that can communicate with each device of the disaster prevention system 100 in FIG. 1 is newly installed separately from the receiver 3, and update information is stored in the installed replacement device. Alternatively, the alternative side detection unit 362 and the alternative side operation unit 363 may be provided so that the alternative device substitutes for the monitoring operation.

(About update information)
Further, in the first embodiment, for the update information of the recording unit 35 in FIG. 1, at least the normal information is received by the receiver 3 at a predetermined timing (for example, a constant interval time or a predetermined time). Some information may be generated and stored by copying.

(About disaster prevention system (1))
Moreover, in Embodiment 2, although the case where the 1st monitoring area side disaster prevention system 400A and the 2nd monitoring area side disaster prevention system 400B monitor the monitoring area of the mutually same monitoring object building was demonstrated, it does not restrict to this. Absent. For example, the first monitoring area side disaster prevention system 400A monitors the monitoring area of the first monitoring target building, and the second monitoring area side disaster prevention system 400B is a second monitoring object that is a building different from the first monitoring target building. You may comprise so that the monitoring area | region of a building may be monitored. That is, you may comprise so that each of these disaster prevention systems may monitor the monitoring area | region of the monitoring object building which mutually differs.

(About disaster prevention system (2))
In the second embodiment, the disaster prevention system 400 is provided with two disaster prevention systems (specifically, the first monitoring area side disaster prevention system 400A and the second monitoring area side disaster prevention system 400B), Although the case where the monitoring operation is replaced between the systems has been described, the present invention is not limited to this. For example, three or more disaster prevention systems may be provided, and the monitoring operation may be substituted between each system.

(About disaster prevention system (3))
In FIG. 5 of the second embodiment, a communication control switch (communication control means) is provided on a communication line that enables the first monitoring area side disaster prevention system 400A and the second monitoring area side disaster prevention system 400B to communicate with each other. When communication between disaster prevention systems is necessary, the communication control switch is turned on to enable communication, and when communication between disaster prevention systems is necessary, the communication control switch is turned off. Communication may be disabled. The communication control switch may be configured to be turned on / off by the control unit of the receiver of each system.

  In addition, in the device line (for example, in the example of FIG. 5, the communication line connecting the first monitoring area side disaster prevention system 400A side and the second monitoring area side disaster prevention system 400B side) identifies the line near the receiver. You may provide the repeater which has the function to do. In order for the device to receive control from a receiver other than the connected receiver (that is, in the example of FIG. 5, the receiver 6 of the first monitoring area side disaster prevention system 400A to which the sensor 4 and the like belong). The receiver identification information (receiver ID) and the line number connected to the line for identifying the relevant line) (in order to be controlled by the receiver 9 of the second monitoring area side disaster prevention system 400B). In addition, an address in the line for specifying a device in the line is required. And if it is connected without a repeater, it is necessary to store the information on the device side as well, but current devices only have addresses within the line, so if you try to apply the system, Changes are required. However, adopting a repeater, storing the receiver identification information and the line number as the line identification information in the repeater, and when receiving the signal from the receiver, if the line identification information matches the signal, By specifying the address in the transmission and transmitting the signal from the device, including the line identification information, it is transmitted in the communication line, so that the device can receive multiple addresses while storing only the addresses in the line as usual. It becomes possible to communicate with the machine.

(About update)
Further, for example, an update request signal may be transmitted to another receiver at the start of the update, and the update may be started when a signal indicating that the preparation for the other person monitoring operation process is completed from the other receiver. Further, for example, the update may not be started while the receiver is in an alarm operation. Further, for example, until the recovery operation is performed when the alarm operation is started during the update monitoring operation process, the update monitoring operation process may be continued without shifting to the normal monitoring operation process even if the update is completed.

(About monitoring operation)
In addition, for example, “monitoring operation” by an alternative system receives an alarm signal from a sensor, sounds a local sound device corresponding to the alarm sensor, activates a smoke control device, and displays an alarm on the receiver itself.・ It is defined that the main function such as alarm sound is activated, and the operation as a “special operation” that is a disaster prevention operation other than the operation by the above main function when the “monitoring operation” by the alternative system is performed Test functions, guidance messages such as operation explanations, special functions that execute fire simulations, etc. may be configured to be inoperable, but if there is no problem with the capacity of the recording unit on the alternative system side (that is, A part or all of the special function may be operable during the alternative operation (when there is sufficient free space in the recording unit).
