(2.2) Alarms Each alarm 2 is, for example, a battery-powered fire alarm. However, the alarm 2 is a fire alarm that is electrically connected to an external power source (for example, a commercial power system) and is driven by converting AC power (for example, an effective value of 100 V) supplied from the external power source into a direct current. There may be.

The five alarms 2 are so-called interlocking alarms, and no matter which alarm 2 detects a fire, the five alarms 2 are interlocked with the other alarms 2 (along with the other alarms 2), and the alarm sounds. It is configured to issue an alarm. The alarm device 2 (interlocking source) at the position of the fire source issues an alarm sound such as "View view fire." On the other hand, the other alarm device 2 (interlocking destination) issues an alarm sound so that the position of the fire source can be specified. Here, as an example, any one of the five alarms 2 functions as a master unit, and the other remaining alarms 2 function as slave units. The alarm device 2 of the master unit stores the identification information of the alarm device 2 which is another slave unit. Hereinafter, the alarm device 2 of the master unit may be referred to as a first alarm device 2A, and the alarm device 2 of the slave unit may be referred to as a second alarm device 2B.

It is assumed that the five alarms 2 are installed in each of the three rooms, the corridor, and the ceiling surface of the stairs on the first floor of the facility 200. Here, it is assumed that the facility 200 is divided into a plurality of management areas A0 (see FIG. 3). In the following, for convenience of explanation, it is assumed that the facility 200 is divided into five management areas A0 based on the area where the alarm 2 is installed on the first floor of the facility 200. In other words, the area where the alarm device 2 is not installed (washroom L1 in FIG. 3) is excluded from the management area A0. However, the area where the alarm 2 is not installed may be one management area A0.

Of the five management areas A0, three rooms are called the first management area A1, the second management area A2, and the third management area A3, respectively, and the corridor connected to the entrance L2 is called the fourth management area A4. The stairs are called the fifth management area A5. The first management area A1 is a kitchen and is connected to the self-propelled door L3. The second management area A2 is a bedroom. The third management area A3 is a living room. The first alarm 2A (master unit) is preferably installed at a position where it can communicate with all four second alarms 2B (slave units). As an example, the first alarm 2A is installed in the fifth control area A5, and the four second alarms 2B are installed in the first to fourth control areas A1 to A4, respectively.

The alarm device 2 will be described below with reference to FIG. The second alarm 2B has substantially the same functions as the first alarm 2A, except for some functions. Therefore, the function of the second alarm 2B, which is substantially common to the first alarm 2A, will be omitted as appropriate, and the function of the second alarm 2B, which is different from the function of the first alarm 2A, will be omitted. It may be explained as appropriate without it.

As shown in FIG. 1, each alarm 2 includes a control unit 20, a first communication unit 21, a second communication unit 22, a battery 23, a notification unit E1 (operating light 24 and an acoustic unit 25), and a detection unit 26. Have. However, the second alarm 2B does not have to include the first communication unit 21. The battery 23 is, for example, a lithium battery, and the alarm 2 is operated by the electric power supplied from the battery 23.

The control unit 20 includes, for example, a computer system. A computer system mainly comprises one or more processors and one or more memories as hardware. The function of the control unit 20 is realized by executing a program recorded in one or more memories of a computer system by one or more processors. The program is pre-recorded in one or more memories of the computer system. The program may be provided through a telecommunication line, or may be recorded and provided on a non-temporary recording medium such as a memory card, an optical disk, or a hard disk drive that can be read by a computer system.

The control unit 20 stores the identification information unique to the own machine. In particular, the control unit 20 of the first alarm 2A stores the unique identification information of the four second alarms 2B and the control device 10. The control unit 20 of the second alarm 2B stores the unique identification information of the first alarm 2A.

The control unit 20 controls the first communication unit 21, the second communication unit 22, the notification unit E1, the detection unit 26, and the like. Further, the control unit 20 controls a power supply circuit that generates operating power of various circuits from the DC power of the battery 23.

The detection unit 26 is configured to detect smoke associated with the occurrence of a fire and change the detection amount (for example, voltage value) according to the amount (concentration) of smoke generated. The detection unit 26 is, for example, a photoelectric sensor that detects smoke. As shown in FIG. 1, the detection unit 26 includes a light emitting unit 261 and a light receiving unit 262. The generation of smoke is detected by the light receiving element of the light receiving unit 262 detecting the scattered light generated by reflecting the light emitted from the light emitting element of the light emitting unit 261 by the smoke particles. Of course, the detection unit 26 may be configured by a heat-sensitive type that detects the occurrence of a fire according to the heat accompanying the occurrence of a fire. The control unit 20 compares the detection amount of the detection unit 26 with the threshold value, and if the detection amount exceeds the threshold value, determines that a fire has occurred.

The first communication unit 21 and the second communication unit 22 transmit and receive radio signals using radio waves as a medium. The first communication unit 21 is configured to communicate with the control device 10. The second communication unit 22 is configured to communicate with another alarm device 2. Each of the first communication unit 21 and the second communication unit 22 has an antenna, a transmission circuit, and a reception circuit. The transmission circuit modulates the data input from the control unit 20 into a wireless signal and transmits it via the antenna. The receiving circuit demodulates the radio signal received via the antenna and outputs the demodulated data to the control unit 20.

The first communication unit 21 performs wireless communication in accordance with a specific low power wireless station defined in Japan, and performs wireless communication with the control device 10 using, for example, a radio wave in the 920 MHz band. On the other hand, the second communication unit 22 performs wireless communication in accordance with, for example, the "radio station of the low power security system" stipulated in Article 6, Paragraph 4, Item 3 of the Radio Law Construction Regulations in Japan. For example, radio waves in the frequency band of 426 MHz are used to perform wireless communication with another alarm device 2. That is, the frequency band used for communication with the control device 10 and the frequency band used for communication between the alarm devices 2 are different from each other. The first communication unit 21 and the second communication unit 22 may be configured as one communication unit integrated with each other, or at least a part of the antenna, the transmission circuit, and the reception circuit may be shared. .. The frequency band used in wireless communication is not limited to the above-mentioned 426 MHz band and 920 MHz band, and can be appropriately changed in accordance with the Radio Law or Fire Service Law of each country.

The first alarm device 2A has a first communication unit 21 and a second communication unit 22 in order to function as a master unit that communicates with both the second alarm device 2B and the control device 10. On the other hand, each second alarm 2B that functions as a slave unit does not have a function of communicating with the control device 10. That is, each second alarm 2B does not have the first communication unit 21. In short, each second alarm 2B has only the second communication unit 22 of the first communication unit 21 and the second communication unit 22, does not communicate with the control device 10, and communicates with the first alarm 2A. It differs in what it does. All of the five alarms 2 also have a function of communicating with the control device 10, and each alarm 2 may be set as a master unit or a slave unit by switching with a DIP switch or the like. In this case, the slave unit The alarm device 2 set to may not use the first communication unit 21.

The notification unit E1 is composed of an operating light 24 and an acoustic unit 25. The notification unit E1 has a function of notifying the occurrence of a fire.

The sound unit 25 outputs sound (sound wave). When the control unit 20 determines that a fire has occurred, the sound unit 25 outputs an alarm sound so as to notify the occurrence of the fire. The acoustic unit 25 includes a speaker that converts an electric signal into sound, an acoustic circuit, and the like. The sound unit 25 outputs an alarm sound (for example, a “beep” sound). The audible alarm may include a voice message such as "Fire. Fire." Further, when the control unit 20 determines that a replacement time, a failure, a battery exhaustion, or the like has occurred, the sound unit 25 outputs a sound (notification sound) for notifying the occurrence. The sound unit 25 outputs an alarm sound and a notification sound on a trial basis even during an operation test. The operation test can be performed by pressing the operation button exposed from the housing of the alarm device 2 or pulling the drawstring derived from the housing. If the operation button is pressed during the alarm, the alarm sound output stops.

The operating light 24 has a red LED (Light Emitting Diode) 240 as a light source, a lighting circuit, and the like. The color of the light source of the operating light 24 is not particularly limited and may be other than red. The operation light 24 is turned off during normal operation (when monitoring a fire). When the control unit 20 determines that a fire has occurred, the operation light 24 starts blinking (or lit) at the same time as the alarm sound starts to be issued, and stops when the alarm sound stops issuing. The light emitted from the operating light 24 is led out to the outside of the housing of the alarm device 2 via a translucent operation button. A person (for example, a resident) in the facility 200 can know that the alarm 2 is operating (fire is being detected) by visually recognizing the red operation blinking through the operation button. When the control unit 20 determines that a replacement time, a failure, a dead battery, or the like has occurred, the operation light 24 blinks to notify the resident of the occurrence. Similar to the acoustic unit 25, the operation test of the operation light 24 can be performed by pressing the operation button or pulling the drawstring.

The third sensing device 33 also wirelessly communicates with the control device 10 by using, for example, a radio wave in the 920 MHz band.

The third sensing device 33 operates in a standby mode with low power consumption when the power is off (non-operating). When the power is turned on (operated) in response to a user operation on the remote controller (may be the control device 10), the third sensing device 33 operates in the sensing mode while executing the air cleaning control. When the control device 10 receives the sensing signal from the third sensing device 33, the control device 10 stores the sensing information (type, concentration, etc.) of the substance contained in the air in the storage unit 15. The user may be able to browse the sensing information through the display unit D1 of the control device 10.

By the way, as described above, the battery-powered first sensing device 31 intermittently activates sensing at 10-minute intervals in order to suppress power consumption during normal times. However, when the first sensing device 31 receives an activation signal from the control device 10 during operation in the standby mode, the first sensing device 31 activates sensing.

The second and third sensing devices 32 and 33 operate in the standby mode with low power consumption when not in operation. However, when the second and third sensing devices 32 and 33 receive the activation signal from the control device 10 during the operation in the standby mode, the second and third sensing devices 32 and 33 activate the sensing (air conditioning control and cleaning control may not be performed). When the second and third sensing devices 32 and 33 receive the start signal from the control device 10 during operation, they execute sensing in the same manner as in the normal state while performing air conditioning control and cleaning control.

When sensing is activated by receiving an activation signal, the sensing execution interval in each sensing device 3 may be the same predetermined interval as the sensing that is spontaneously executed in normal times. That is, when a fire (disaster) is detected by the alarm device 2, the control device 10 may match the timing of receiving the sensing signal with a predetermined interval. In this case, the load (for example, power consumption) on the sensing device 3 side can be suppressed.

However, in the battery-powered first sensing device 31, the predetermined interval is relatively long. Therefore, the sensing execution interval after receiving the activation signal may be switched to an interval shorter than a predetermined interval at the normal time. In other words, the sensing device 3 may voluntarily execute sensing at predetermined intervals, and may execute sensing at regular intervals shorter than the predetermined intervals if specific conditions are satisfied. When a fire is detected by the alarm device 2, the control device 10 may match the timing of receiving the sensing signal at regular intervals. In this case, the sensing signal contains information about the results of sensing performed at regular intervals. The specific condition is, for example, that a start-up signal has been received.

(2.5) Accuracy of Fire Detection Here, the control unit C1 of the control device 10 (control system 1) has an output processing unit 12 and a setting unit 13 as shown in FIG. That is, the control unit C1 has a function as an output processing unit 12 and a function as a setting unit 13. In other words, the control system 1 includes an output processing unit 12 and a setting unit 13.

The output processing unit 12 outputs the accuracy of the alarm device 2 for fire detection from the detection status of the alarm device 2 and the sensing status of the sensing device 3 based on the device signal received by the reception unit 141 in a identifiable form. It is configured to do. Here, the output processing unit 12 outputs the accuracy of the alarm device 2 with respect to the fire detection in a form that can be specified based on the sensing signal received from the sensing device 3 by activating the sensing. In the following, information that can specify the accuracy of fire detection may be referred to as "specific information".

The "form in which accuracy can be specified" referred to in the present disclosure may be any form in which a user (for example, a resident) can estimate the accuracy for fire detection to some extent by obtaining specific information. The "form in which accuracy can be specified" may include, for example, the following first and second forms. Here, the output processing unit 12 outputs specific information in both the first form and the second form, but only one of the forms may be used.

The first form is a form in which the sensing result of the sensing device 3 is directly notified. The first form may be, for example, a form in which the sensing result of the sensing device 3 is graphed and notified. Specifically, the output processing unit 12 sets the time elapsed for a specific physical quantity sensed by the sensing device 3 in real time, starting from the time when the detection signal from the alarm device 2 is received (may be a little before). The accompanying changes may be graphed and output as specific information. When an image pickup device such as a camera is included in the plurality of sensing devices 3, the first form may be a form of notifying an image (which may be a moving image or a still image) as a sensing result of the sensing device 3.

The second form is a form in which the control unit C1 determines the accuracy based on the sensing result of the sensing device 3 and notifies the determination result. As shown in FIG. 1, the output processing unit 12 of the present embodiment has a determination unit 120 for determining the accuracy of the alarm device 2 for fire detection, and outputs the determination result by the determination unit 120. In other words, the output processing unit 12 has a function as a determination unit 120. The determination unit 120 analyzes the sensing result and evaluates the accuracy of fire detection. The determination unit 120 may, for example, digitize the evaluation result (for example, a percentage) and output it as specific information. The determination unit 120 may analyze the sensing result and evaluate the accuracy based on, for example, the trained model generated by machine learning.

Specific information is notified by screen display. For example, the output processing unit 12 displays specific information among the display unit D1 of the control device 10, the display unit of the information terminal 4 carried by the resident, and the display unit of the television receiver (smart TV) that can connect to the Internet. Have at least one output to the screen. However, the specific information may be notified by voice output. The output processing unit 12 may output specific information from at least one of the speaker of the control device 10, the speaker of the information terminal 4, and the speaker of the smart TV.

FIG. 4 shows how the specific information is notified by the screen display from the information terminal 4. In the example of FIG. 4, the fact that a fire has been detected, the location where the fire has occurred, and the reliability of the detection (30% in the illustrated example) are notified. That is, in FIG. 4, the specific information is output as the "reliability" in the second form. The method of displaying the reliability is not particularly limited. For example, the result of evaluation in five stages may be notified, or may be notified in a pie chart and color-coded. In addition, the factor that lowers the reliability (the reason why it was evaluated as 30%) may be notified. Further, in the example of FIG. 4, "25 ° C.", which is the sensing result of the first sensing device 31, is also notified, that is, the specific information is output even in the first form.

The setting unit 13 sets the sensing device 3 so as to be included in the device group X1. That is, for example, when the control device 10 is newly introduced, or when one or a plurality of electric devices managed by the control device 10 are newly introduced, the electric device is transferred to the device group X1 as the sensing device 3 by the setting unit 13. It is possible to register to be included.

The setting unit 13 also sets the alarm device 2 so that it is included in the device group X1. That is, when the alarm device 2 is newly introduced or added, the setting unit 13 can register the alarm device 2 so as to be included in the device group X1. The control unit C1 stores the setting information regarding the device group X1 in the storage unit 15.

Regarding the setting information related to the device group X1, new registration, change, deletion, etc. are possible by operating the user interface. The "user interface" referred to in the present disclosure corresponds to any one of a touch panel type display unit D1, an operation button attached to the side of the display unit D1, and an information terminal 4, but is not particularly limited.

The storage unit 15 may store in advance image information for outputting the floor plan of the facility 200 as an image on the display unit D1. The image information is not limited to the floor plan (plan view) of the facility 200, and may be image information related to the three-dimensional view of the facility 200. The image information may be downloaded from an external server 5 managed by a house maker or the like of the facility 200.

In the present embodiment, the device group X1 includes a plurality of sensing devices 3. Then, the setting unit 13 sets the plurality of sensing devices 3 so as to be classified into one or a plurality of groups G0 (see FIG. 3) according to predetermined group conditions. Here, it is assumed that the predetermined group conditions include information regarding the installation position of each sensing device 3.

Specifically, the setting unit 13 sets, for example, the sensing device 3 installed in the first management area A1 so as to be classified into the first group G1. Further, the setting unit 13 sets the sensing device 3 installed in the second management area A2 so as to be classified into the second group G2. Further, the setting unit 13 sets the sensing device 3 installed in the third management area A3 so as to be classified into the third group G3. In short, the setting unit 13 classifies the group G0 with the management area A0 in which each sensing device 3 is installed as a unit of the installation position.

Further, in the present embodiment, the device group X1 includes a plurality of alarm devices 2. The setting unit 13 sets each of the plurality of groups G0 to include at least one alarm device 2 among the plurality of alarm devices 2. The setting unit 13 sets the second alarm 2B installed in the first management area A1 so as to be included in the first group G1. Further, the setting unit 13 sets the second alarm 2B installed in the second management area A2 so as to be included in the second group G2. Further, the setting unit 13 sets the second alarm 2B installed in the third management area A3 so as to be included in the third group G3.

FIG. 3 shows an example of an image of the floor plan of the facility 200 that can be displayed on the display unit D1 or the information terminal 4 or the like. For example, the user (resident, builder, etc.) touches a predetermined area while looking at the image of the floor plan displayed on the display unit D1 or the information terminal 4, and the sensing device 3 and the alarm device 2 are set as a device group. It may be possible to register so as to be included in X1. In particular, the user may be able to register in which management area A0 the sensing device 3 and the alarm device 2 are installed, respectively, while viewing the image.

When the setting unit 13 receives an operation input for designating the installation position of the sensing device 3 and the alarm device 2 through the user interface in this way, the setting unit 13 classifies each device into group G0 according to the operation input and uses it as group information. It is stored in the storage unit 15.

By providing the setting unit 13, the sensing device 3 can be appropriately selected according to the environment or request in which the control system 1 is introduced.

In the example of FIG. 3, the square marks "1" to "3" indicate the first sensing device 31 to the third sensing device 33, respectively. In the example of FIG. 3, the alarm device 2 (slave unit) and one each of the first sensing device 31 to the third sensing device 33 belong to the first group G1. One each of the alarm device 2 (slave unit), the first sensing device 31, and the second sensing device 32 belongs to the second group G2. One alarm device 2 (slave unit) and one second sensing device 32 belong to the third group G3.

When the detection signal is actually received from the alarm device 2, the output processing unit 12 acquires the identification information of the alarm device 2 which is the fire detection source (fire source) from the received detection signal. The output processing unit 12 identifies the group G0 to which the alarm device 2, which is the detection source of the fire, belongs from among the plurality of groups G0. The output processing unit 12 outputs the accuracy for fire detection in a form that can be specified based on the sensing status of the sensing device 3 belonging to the specified group G0.

(2.6) Operation explanation [Operation example 1: False alarm of alarm]
Hereinafter, the operation of the disaster prevention system 100 will be described with reference to FIG. In the following, as an example, it is assumed that the second alarm 2B installed in the first control area A1 (kitchen) detects a fire while the resident of the facility 200 is out. However, there is a possibility that a fire has not actually occurred and it is a false alarm. Examples of causes of false alarms include intrusion of dust, steam, etc. into the alarm device 2, and aged deterioration of the alarm device 2.

The alarm device 2 (second alarm device 2B) installed in the first management area A1 detects a fire (step S1). The alarm device 2 issues an alarm sound (step S2) and transmits an alarm signal (interlocking signal) to the first alarm device 2A, which is a master unit (step S3). When the first alarm device 2A receives the alarm signal from the alarm device 2, the first alarm device 2A also issues an alarm sound to the other alarm device 2, and also transmits the alarm signal to the other alarm devices 2 to link the alarm sound. Step S4). Further, the first alarm device 2A transmits a detection signal to the control device 10 (step S5).

When the control device 10 receives the detection signal, the control device 10 identifies the group G0 to which the fire alarm 2 belongs (step S6). Here, the control device 10 identifies that the group G0 of the alarm device 2 at the fire source is the first group G1. The control device 10 transmits an activation signal to the three sensing devices 3 belonging to the first group G1 using radio waves in the 920 MHz band (step S7). Here, it is assumed that the start signal is transmitted only to the sensing device 3 belonging to the first group G1, but the start signal may be transmitted by broadcasting without specifying the group G0. That is, the control device 10 may simultaneously transmit the activation signal to all the sensing devices 3 in the facility 200.

Each sensing device 3 of the first group G1 activates sensing when it receives an activation signal (step S8). Here, each sensing device 3 executes sensing at a fixed interval (for example, 1 minute interval) shorter than a predetermined interval (for example, 10 minutes or 5 minutes) at a normal time, and controls the sensing signal each time. (Step S9).

When the sensing result (detection amount) received from each sensing device 3 reaches a certain number of samples, the control device 10 evaluates the accuracy of fire detection (step S10). If the fire detection is a false alarm, it is highly possible that the sensing results (temperature) of the first and second sensing devices 31 and 32 indicate room temperature (for example, 25 ° C.). If the fire detection is a false alarm, it is unlikely that the sensing result (type and concentration of the substance in the air) of the third sensing device 33 indicates the presence of the substance caused by the fire smoke generated by the fire.

The control device 10 mutually evaluates the accuracy from the sensing results of these three sensing devices 3. The control device 10 may weight the type of the sensing device 3 and evaluate the accuracy. The control device 10 may evaluate the accuracy based on the product number information of the sensing device 3 and the alarm device 2 in consideration of aging deterioration. When the control device 10 simultaneously transmits the start signal to all the sensing devices 3 in the facility 200, the control device 10 may mutually evaluate the accuracy from the sensing results of all the sensing devices 3.

The control device 10 transmits a notification signal including the fact that a fire has been detected, the location of the fire source, and specific information (reliability, indoor temperature, indoor substance concentration, etc.) to the information terminal 4 (step S11). When the information terminal 4 receives the notification signal, the information terminal 4 notifies the information included in the notification signal on the screen (step S12). After that, the control device 10 continues to update the specific information notified from the information terminal 4 in real time, for example, for a certain period of time. When the control device 10 receives a specific operation input by the user interface (may be an application for "existence" described later), the control device 10 simultaneously transmits a signal so as to return each sensing device 3 to a normal operation.

Further, the control device 10 may transmit the notification signal to the external server 5 in addition to the information terminal 4. The external server 5 stores specific information included in the notification signals received from the control devices 10 of a large number of facilities 200, the location of the facility 200, the location where the fire is detected, the time zone at the time of detection, the season, the weather, and the like. You may. The information stored in the external server 5 may be used to analyze factors that are likely to cause false alarms.

[Operation example 2: Alarm error]
The disaster prevention system 100 may operate so as to deal with the false alarm of the alarm device 2 as follows.

The control device 10 may be configured to receive an operation input for applying for "at home" or "absent (going out)" via the user interface. The control device 10 may execute the monitoring mode by accepting an application for "absence" from the resident when the resident goes out. When the control device 10 starts the monitoring mode, the control device 10 simultaneously transmits an activation signal to all the sensing devices 3 in the facility 200.

Each sensing device 3 in the facility 200 activates sensing when it receives an activation signal. However, each sensing device 3 executes sensing at the same interval as a predetermined interval (for example, 10 minutes or 5 minutes) at a normal time, and transmits a sensing signal to the control device 10 each time.

The control device 10 evaluates the accuracy of the alarm device 2 for fire detection from the detection status of the alarm device 2 and the sensing status of the sensing device 3. That is, the control device 10 monitors the sensing status of the sensing device 3 even if the detection signal is not received from the alarm device 2. When the control device 10 evaluates that the possibility that a fire has occurred is not zero when the sensing result of the sensing device 3 exceeds a certain threshold value, a false alarm is reported even if the detection signal is not received from the alarm device 2. The possibility of the above, the temperature in the room, the concentration of substances in the room, and the like are transmitted to the information terminal 4.

When the resident returns home and accepts the application for "resident", the control device 10 simultaneously transmits a signal so as to return each sensing device 3 to the normal operation, and cancels the monitoring mode.

[advantage]
As described above, in the present embodiment, the output processing unit 12 outputs the accuracy of fire detection in a form that can be specified. As a result, the user (for example, a resident) can obtain in a form that can identify that there is a possibility of false alarm or false alarm regarding the detection of fire. Therefore, it is possible to improve measures related to the reliability of detection of the alarm device 2.

Further, since the control system 1 (control device 10) activates the sensing to the sensing device 3 by using the reception of the detection signal as a trigger, the reliability of the specific information is improved. Further, in the present embodiment, since the sensing result is obtained at a constant interval shorter than a predetermined interval, the reliability of the specific information is improved. Further, in the present embodiment, the setting unit 13 sets the plurality of sensing devices 3 and the alarm device 2 so as to be classified into one or a plurality of groups G0 according to predetermined group conditions (here, information on the installation position is included). Therefore, the reliability of specific information is improved.

In particular, the output processing unit 12 can specify the group G0 to which the alarm device 2 which is the detection source of the fire belongs, and can specify the accuracy for the detection of the fire based on the sensing status of the sensing device 3 belonging to the specified group G0. Output in various forms. Therefore, the possibility that the sensing status of the less relevant sensing device 3 is used is reduced, and the reliability of the specific information is further improved.

(3) Modified Example The above embodiment is only one of various embodiments of the present disclosure. The above-described embodiment can be changed in various ways depending on the design and the like as long as the object of the present disclosure can be achieved. The control system 1 according to the above embodiment may be embodied by a processing method, a computer program, a non-temporary recording medium on which a computer program is recorded, or the like. The processing method includes a receiving step and an output processing step. In the reception step, the device signal is received from the device group X1. The device group X1 includes an alarm device 2 for detecting the occurrence of a fire and a sensing device 3 other than the alarm device 2 for sensing a specific physical quantity. In the output processing step, the accuracy of the alarm 2 for fire detection is output in a identifiable form from the detection status of the alarm device 2 and the sensing status of the sensing device 3 based on the device signal received in the reception step. ..

The following is a list of modified examples of the above embodiment. The modifications described below can be applied in combination as appropriate. Hereinafter, the above embodiment may be referred to as a “basic example”.

The control system 1 (control device 10) in the present disclosure includes a computer system. The main configuration of a computer system is a processor and memory as hardware. The function as the control system 1 in the present disclosure is realized by the processor executing the program recorded in the memory of the computer system. The program may be pre-recorded in the memory of the computer system, may be provided through a telecommunication line, and may be recorded on a non-temporary recording medium such as a memory card, optical disk, hard disk drive, etc. that can be read by the computer system. May be provided. A processor in a computer system is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or a large scale integrated circuit (LSI). The integrated circuit such as an IC or LSI referred to here has a different name depending on the degree of integration, and includes an integrated circuit called a system LSI, VLSI (Very Large Scale Integration), or ULSI (Ultra Large Scale Integration). Further, an FPGA (Field-Programmable Gate Array) programmed after the LSI is manufactured, or a logical device capable of reconfiguring the junction relationship inside the LSI or reconfiguring the circuit partition inside the LSI should also be adopted as a processor. Can be done. A plurality of electronic circuits may be integrated on one chip, or may be distributed on a plurality of chips. The plurality of chips may be integrated in one device, or may be distributed in a plurality of devices. The computer system referred to here includes a microcontroller having one or more processors and one or more memories. Therefore, the microcontroller is also composed of one or more electronic circuits including a semiconductor integrated circuit or a large-scale integrated circuit.

Further, it is not an essential configuration for the control system 1 that a plurality of functions in the control system 1 are integrated in one housing. The components of the control system 1 may be distributed in a plurality of housings. On the contrary, a plurality of functions in the control system 1 may be integrated in one housing. Further, at least a part of the functions of the control system 1, for example, a part of the functions of the control system 1 may be realized by a cloud (cloud computing) or the like.

In the basic example, with respect to the setting unit 13, the predetermined group condition includes information on the installation position of each sensing device 3 (management area A0 in the basic example). That is, in the basic example, the sensing devices 3 are grouped based on their installation positions. However, the predetermined group conditions may include information about the type of sensing device 3. For example, the first sensing device 31 and the second sensing device 32 that perform sensing related to temperature and humidity may be the first group, and the third sensing device 33 that performs sensing related to substances in the air may be the second group. In particular, in the basic example, the explanation is based on the assumption that the disaster is a fire, but depending on the type of disaster (for example, the occurrence of a gas leak), the sensing result regarding temperature and humidity may not be necessary. In this case, the control device 10 may transmit an activation signal to the sensing device 3 belonging to the second group.

In the basic example, when the control device 10 receives the detection signal from the first alarm device 2A, the control device 10 transmits the activation signal to the sensing device 3. However, transmission of the activation signal from the control device 10 is not essential. For example, the sensing device 3 may receive the detection signal directly from the first alarm device 2A. When the sensing device 3 receives the detection signal from the first alarm device 2A, the sensing device 3 may activate sensing and transmit the sensing signal to the control device 10. Further, in this case, the above-mentioned "specific condition" is that the detection signal is received from the first alarm device 2A. Both the sensing device 3 and the first alarm device 2A are devices that communicate using radio waves in the 920 MHz band, and a configuration for directly transmitting and receiving detection signals can be easily realized.
