The signal processing unit 20 has, for example, a computer system having a processor and a memory. Then, when the processor executes the program stored in the memory, the computer system functions as the signal processing unit 20.

The signal processing unit 20 has the functions of the acquisition unit 21 and the precursor determination unit 22 described above, and further has the functions of the notification unit 23 and the processing unit 24.

The acquisition unit 21 via the first communication unit 31 includes a fire detector 1, a smoke detection unit 2, a temperature detection unit 6, a color vision detection unit 7, an odor detection unit 8, and a current abnormality detection unit 9, which are detection units D1.

Further, the acquisition unit 21 acquires the installation location information regarding the installation location from each of the one or more detection units D1, and stores the acquired installation location information in the storage unit 33. The acquisition unit 21 may acquire the installation location information indicating the installation location of the detection unit D1 input by the user using the information terminal 50 or the like from the information terminal 50 via the second communication unit 32.

The precursor determination unit 22 determines the precursor of an abnormal event including at least a fire based on the detection result of the detection unit D1 acquired by the acquisition unit 21. Further, when the precursor determination unit 22 determines the precursor of the abnormal event, the precursor determination unit 22 determines the location where the precursor of the abnormal event occurs based on the installation location information of the detection unit D1 stored in the storage unit 33. The process of determining the precursor of an abnormal event by the precursor determination unit 22 will be described in more detail in "(2.3) Precursor determination process".

The notification unit 23 outputs the determination result of the precursor determination unit 22 to the external system. The external system may include, for example, at least one of an information terminal 50 used by a user who uses the facility 100 and an external server 200 operated by a business operator or the like that provides a service for remotely monitoring the facility 100. Specifically, the notification unit 23 causes the second communication unit 32 to transmit the determination result of the precursor determination unit 22 to the external system (information terminal 50, external server 200, etc.). When the precursor determination unit 22 determines the location where the precursor of the abnormal event occurs, the notification unit 23 transmits the location information regarding the location of the precursor of the abnormal event to the external system (information terminal 50, external server 200, etc.). You may send it.

The processing unit 24 cooperates with the fire detector 1 to perform processing based on the determination result of the precursor determination unit 22. For example, when the precursor determination unit 22 detects the precursor of an abnormal event, the processing unit 24 increases the sensitivity of the fire detector 1 to detect the fire as compared with the case where the precursor of the abnormal event is not detected. , Adjust the sensitivity of the fire detector 1. As a result, when the precursor of the abnormal event is detected, the sensitivity of the fire detector 1 is set to be higher than that when the precursor of the abnormal event is not detected, so that the fire detection omission is reduced. can. Further, when the precursor of the abnormal event is not detected, the sensitivity of the fire detector 1 is set to be lower than that when the precursor of the abnormal event is detected, so that the false detection of the fire can be reduced.

Further, the signal processing unit 20 (control system 10) has a function of cooperating with the fire extinguishing system 60 arranged in the facility 100. When the precursor determination unit 22 detects a precursor of a fire, the signal processing unit 20 (control system 10) causes the fire extinguishing system 60 to perform a fire extinguishing operation. Therefore, the control system 10 can start the fire extinguishing operation at the stage when the precursor determination unit 22 determines that there is a precursor of the fire in the fire extinguishing system 60 that performs the fire extinguishing operation after the fire detector 1 detects the fire. For example, when the precursor determination unit 22 determines that there is a precursor of a fire based on the smoke detection result by the smoke detection unit 2 or the carbon monoxide detection result by the gas detection unit 2, the fire extinguishing system 60 executes a fire extinguishing operation. You may let me. In this way, since the fire extinguishing system 60 extinguishes the fire before the fire detector 1 detects the fire, it is possible to extinguish the fire before the fire detector 1 detects the fire, and the fire detector 1 can extinguish the fire. If the fire can be completely extinguished before the fire is issued, it is possible to eliminate the need for reporting and post-processing to the fire department. When the precursor determination unit 22 detects a precursor of a fire, the signal processing unit (control system 10) may operate a fire door system other than the fire extinguishing system 60 or a disaster prevention system such as a smoke exhaust system to spread the fire. Can be suppressed.

(2.2) Operation Description The operation of the control system 10 of the present embodiment will be described with reference to FIGS. 3 and 4 and the like. The flowchart shown in FIG. 3 is merely an example of the control method according to the present embodiment, and the order of the processes may be changed as appropriate, and the processes may be added or omitted as appropriate.

The detection unit D1 (fire detector 1, smoke detection unit 2, temperature detection unit 6, color vision detection unit 7, odor detection unit 8, and current abnormality detection unit 9) arranged in the facility 100 performs a detection operation at an appropriate timing. Is going. The acquisition unit 21 of the control system 10 performs a process (first process) of acquiring a detection result from the detection unit D1 via the first communication unit 31 (ST1). For example, the acquisition unit 21 may perform a process of acquiring information indicating the detection result from the detection unit D1 every time a certain time elapses, or acquires information indicating the detection result from the detection unit D1 triggered by some event. You may perform the process of doing. Further, the acquisition unit 21 may acquire information indicating the detection result transmitted from the detection unit D1 at an arbitrary timing.

Next, the precursor determination unit 22 performs a process (second process) of determining a precursor of an abnormal event including at least a fire based on the detection result of the detection unit D1 acquired by the acquisition unit 21 (ST2). The judgment process by the precursor determination unit 22 will be described in more detail in "(2.3) precursor determination process".

When the precursor determination unit 22 determines in the second process that there is no precursor of an abnormal event (ST3: No), the control system 10 ends the process.

When the precursor determination unit 22 determines in the second process that there is a precursor of an abnormal event (ST3: Yes), the notification unit 23 of the control system 10 uses the external system (information terminal 50 and the outside) via the second communication unit 32. A notification process for outputting the determination result of the precursor determination unit 22 to the server 200) is performed (ST4). When the precursor determination unit 22 determines the location where the precursor has occurred, the notification unit 23 determines that the external system has a precursor of an abnormal event via the second communication unit 32. It suffices to output the occurrence place information about the occurrence place where the precursor occurred.

Further, when the signal processing unit 20 of the control system 10 determines that the precursor determination unit 22 has a precursor of a fire, the signal processing unit 20 operates the fire extinguishing system 60 to cause the fire extinguishing system 60 to execute the fire extinguishing process (ST5).

The control system 10 repeatedly executes the processes ST1 to ST5, determines the presence or absence of a precursor of an abnormal event at the facility 100, and if it is determined that there is a precursor, the determination result of the precursor of the abnormal event is determined by the external system (information terminal). It can be output to 50 and an external server 200, etc.).

Here, the information terminal 50 that has received the determination result of the precursor of the abnormal event from the control system 10 performs a process of notifying the user who uses the information terminal 50 of the determination result of the precursor of the abnormal event. As a result, the user of the information terminal 50 can predict the occurrence of the abnormal event at a stage before the occurrence of the abnormal event based on the determination result of the precursor of the abnormal event, and the abnormal event that will occur in the future can be predicted. It will be possible to take prompt action against it.

(2.3) Precursor determination process The precursor determination unit 22 determines whether or not a precursor of an abnormal event including at least a fire has occurred based on the detection result of the detection unit D1.

Here, a process in which the precursor determination unit 22 determines the precursor of a fire based on the detection result of the fire-related event by the detection unit D1 will be described.

The precursor determination unit 22 has, for example, a condition that the temperature detected by the temperature detection unit 6 exceeds the reference value, a condition that the concentration of smoke detected by the smoke detection unit 2 exceeds the first reference concentration, and an odor detection unit 8. If at least one of the conditions that the concentration of the odor component detected by the above exceeds the second reference concentration is satisfied, it is determined that there is a sign of fire. Further, the precursor determination unit 22 may determine that there is a precursor of a fire when the current abnormality detection unit 9 detects an abnormality of the current flowing through the electric device 90.

When the precursor determination unit 22 determines that there is a precursor of an abnormal event based on the detection result by the detection unit D1, the precursor determination unit 22 determines the location where the precursor of the abnormal event occurs based on the installation location information stored in the storage unit 33. do. Here, since the notification unit 23 outputs the determination result that there is a precursor of the abnormal event and the occurrence location information indicating the occurrence location of the precursor of the abnormal event to the external system, the user of the external system has the precursor of the abnormal event. It is possible to grasp the place where it occurred. Therefore, the user of the external system can quickly respond to the precursor of the abnormal event.

Further, the precursor determination unit 22 may determine the precursor of an abnormal event based on the transition of the detection result of the detection unit D1. For example, the precursor determination unit 22 states that a precursor of an abnormal event (fire) has occurred when the temperature detected by the temperature detection unit 6 is equal to or higher than the reference value T1 (see FIG. 4) for a predetermined duration of DT1 or longer. to decide. In this way, the precursor determination unit 22 determines the precursor of an abnormal event based on the transition of the detection result of the detection unit D1, and if the detection result of the detection unit D1 temporarily exceeds the reference value, an abnormality occurs. Since it is not determined that it is a precursor of an event, the possibility of erroneously detecting a precursor of an abnormal event can be reduced. The precursor determination unit 22 also determines that the detection result of the detection unit D1 other than the temperature detection unit 6 has a precursor of an abnormal event based on the transition of the detection result of the detection unit D1 other than the temperature detection unit 6. However, false detection of precursors of abnormal events can be reduced.

Here, the precursor determination unit 22 may change the method of determining the precursor of an abnormal event based on the detection result in each of the plurality of detection units D1. For example, when the acquisition unit 21 acquires the detection result from the plurality of temperature detection units 6, the precursor determination unit 22 changes the reference value T1 or the duration DT1 in each of the plurality of temperature detection units 6. The temperature detection unit 6 installed in the kitchen of the facility 100 sets the reference value T1 higher and the duration DT1 shorter than the temperature detection unit 6 installed in the space without fire. As a result, the possibility that the precursor determination unit 22 erroneously determines that the temperature rise due to the heat of the cooking utensil is a precursor of a fire can be reduced, and when the temperature detected by the temperature detection unit 5 becomes the reference value T1 or higher, By determining that a sign of fire has occurred in a short period of time, it is possible to take prompt action.

Further, the acquisition unit 21 has acquired the color discrimination results of the plurality of temperature sensitive elements 71 from the color vision detection unit 7, and the precursor determination unit 22 has acquired the color discrimination results of the plurality of temperature sensitive elements 71 by the color vision detection unit 7. Based on the above, the temperature at the installation location of the plurality of temperature sensitive elements 71 is obtained. Here, if the air conditioning system that controls the air conditioning of the space in which the plurality of temperature sensing elements 71 are installed is operating normally, the temperature determined from the colors of the plurality of temperature sensing elements 71 is set in the air conditioning system. It becomes almost the same as the temperature. The precursor determination unit 22 compares the temperature determined from the colors of the plurality of temperature sensitive elements 71 with the set temperature of the air conditioning system, and if the difference between the two exceeds a predetermined error range, the difference from the set temperature is large. It is judged that some kind of abnormal event is occurring in the air conditioning system in a large place. In this way, the precursor determination unit 22 determines the installation location where the precursor of the abnormal event has occurred based on the color discrimination result of the plurality of temperature sensitive elements 71 by the color vision detection unit 7, so that the precursor determination unit 22 can be used as a precursor of the abnormal event. You can take prompt action against it.
