(processing)
Next, the processing executed by the disaster prevention system 100 and the center device 3 configured in this way will be described. Specifically, the information storage process and the information transmission process will be described.

(Processing-Information storage processing)
FIG. 4 is a flowchart of the information storage process (in the following description of each process, the step is abbreviated as “S”). The "information storage process" is a process for storing disaster prevention information on the receiver side of the recording unit 25 of FIG. 1, and specifically, the receiver 2 and the sensor 1 communicate with each other to receive the information. This is a process for storing disaster prevention information on the aircraft side. The timing for executing this information storage process is arbitrary. For example, the information storage process is assumed to be started after the power of each device of the disaster prevention system 100 is turned on and repeatedly executed at predetermined time intervals. It will be explained after it is started. Here, for example, the information storage process will be described below assuming that the information storage process is repeatedly executed about every 30 seconds.

First, as shown in FIG. 4, in SA1, the acquisition unit 261 of the receiver 2 transmits an information request in order to request information from the sensor 1 in FIG. The specific request to be transmitted is arbitrary, but here, for example, the sensor ID of the sensor connected to the receiver 2 (hereinafter, the connection sensor ID) (here, the connection sensor ID) is sent to the recording unit 25 of the receiver 2. Then, it is assumed that "IDa1") is recorded. Specifically, regarding SA1, the connection sensor ID of the recording unit 25 is acquired, an information request including the acquired connection sensor ID is generated, and the generated information request is transmitted via the communication unit 21. Here, for example, an information request including "IDa1" is generated and transmitted.

Returning to FIG. 4, on the other hand, in SB1, the control unit 14 of the sensor 1 determines whether or not there is a request for information to itself. The specific determination method is arbitrary, but here, for example, after receiving the information request transmitted by SA1 via the communication unit 11, the connection sensor ID of the received information request and its own recording unit. It is compared with the sensor ID of 13 and determined as follows. Specifically, if the two objects to be compared do not match each other, it is determined that there was no request for information to the self (NO in SB1), and there is a request for information to the self. SB1 is repeatedly executed until it is determined that the information has been obtained. Further, when the two objects to be compared match each other, it is determined that there is a request for information to the self (YES in SB1), and the process proceeds to SB2. Here, for example, when an information request including "IDa1" is received, the information request "IDa1" and the recording unit 13 "IDa1" match each other, so that the information is requested to itself. Judge as something.

Returning to FIG. 4, in SB2, the control unit 14 of the sensor 1 acquires the smoke concentration. Specifically, the detection unit 12 of FIG. 1 is operated to acquire the concentration of smoke detected by the detection unit 12. Here, for example, "3.5" is acquired.

Returning to FIG. 4, the control unit 14 of the sensor 1 in SB3 transmits information. The specific information to be transmitted is arbitrary, but here, for example, it is assumed that the sensor 1 of FIG. 1 is provided with a timekeeping means for specifying the time when the smoke concentration is detected by SB2. After specifying the detection time of the smoke concentration based on the timekeeping result of the timekeeping means, the information is transmitted as follows. Specifically, regarding SB3, the sensor ID of its own recording unit 13, the smoke concentration acquired by SB2, and the detection time of the specified smoke concentration are acquired, and the acquired information is transmitted via the communication unit 11. To do. Here, for example, "IDa1", "3.5", and "10:10:00" are acquired and transmitted.

Returning to FIG. 4, on the other hand, in SA2, the acquisition unit 261 of the receiver 2 receives the information. Specifically, the information transmitted by SB3 is received and acquired via the communication unit 21 of FIG. Here, for example, the information of "IDa1", "3.5", and "10:10:00" is received and acquired.

Returning to FIG. 4, in SA3, the acquisition unit 261 of the receiver 2 stores the information. Specifically, the information received by the SA2 is stored as the disaster prevention information on the receiver side of the recording unit 25. Here, for example, "IDa1", "3.5", and "101000" in the uppermost row of FIG. 3 (the uppermost row of the information in which numerical values are specifically shown) are recorded. This ends the information storage process.

(Processing-Information transmission processing)
FIG. 5 is a flowchart of information transmission processing. The "information transmission process" is a process of transmitting the target information, and specifically, a process of transmitting the target information from the receiver 2 to the center device 3. The timing of executing this information transmission process is arbitrary, but for example, it is activated after the power of each device of the disaster prevention system 100 is turned on, and has a longer time interval (for example, 5 times) than the information storage process of FIG. It will be described after the information transmission process of FIG. 5 is started, assuming that the information transmission process is repeatedly executed every 10 times, etc.). Here, for example, it will be described below assuming that the information transmission process is repeatedly executed about every 2 minutes and 30 seconds.

First, as shown in FIG. 5, the detection unit 262 of the receiver 2 in SC1 determines whether or not a predetermined sign regarding disaster prevention has been detected. The specific determination method is arbitrary, but here, for example, the control unit 14 of the sensor 1 in FIG. 1 records the concentration of smoke detected by the detection unit 12 in the same manner as in the conventional case, and the fire in the recording unit 13. When the smoke concentration is less than the fire caution threshold, both the pre-alarm and the alarm signal are not output by repeatedly comparing the caution threshold and the fire judgment threshold at predetermined time (for example, about 30 seconds, etc.). In addition, when the smoke concentration is equal to or higher than the fire caution threshold and lower than the fire judgment threshold, a pre-alarm including its own detector ID is generated and transmitted to the receiver 2, and the smoke concentration is equal to or higher than the fire judgment threshold. In this case, it is assumed that the alarm signal including its own sensor ID is transmitted to the receiver 2, and processing is performed as follows. Specifically, regarding SC1, the detection unit 262 of the receiver 2 monitors the communication unit 21 and receives a pre-alarm within a predetermined time (arbitrary, for example, 30 seconds to 1 minute). It is determined that a predetermined sign has been detected (YES in SC1), and the process proceeds to SC2. Further, when the communication unit 21 is monitored and the pre-alarm is not received within the predetermined time, it is determined that the predetermined sign has not been detected (NO of SC1), and the process proceeds to SC4. Here, for example, when the detection unit 12 of the sensor 1 detects "3.5", the pre-alarm is not transmitted, so that the detection unit 262 of the receiver 2 determines that the sign has not been detected. Further, for example, when the detection unit 12 of the sensor 1 detects "5.6", a pre-alarm is transmitted, so that the detection unit 262 of the receiver 2 determines that the sign is detected.

Returning to FIG. 5, in SC2, the acquisition unit 261 of the receiver 2 acquires the predictive time information. Here, the "predictive time information" is information acquired when a sign is detected. For example, in the disaster prevention information on the receiver side of FIG. 2, a plurality of consecutive sets of detection time information (specifically, Information on the sensor ID, smoke concentration information, and detection time information). The specific acquisition method in SC2 is arbitrary, but here, for example, the information storage process of FIG. 4 is executed about every 30 seconds, and the detection time information of FIG. 2 is every about 30 seconds. Since the information transmission process of FIG. 5 is repeatedly executed about every 2 minutes and 30 seconds, each time the information transmission process is executed, the information storage process of FIG. 4 is performed in 5 sets as an example regarding the detection time information. Considering that each new record is taken into consideration, the latest 5 sets of information regarding the detection time information are acquired as predictive time information. Here, for example, when the information storage process of FIG. 4 is repeatedly executed and all the information indicated by the numerical values in the disaster prevention information on the receiver side of FIG. 2 is recorded, the information of the set of "101030" is recorded. (That is, the information of the set of "IDa1", "3.6", and "101030") The information of the set of "101230" is acquired as the information for the predictive time.

Returning to FIG. 5, the transmission control unit 263 of the receiver 2 in SC3 transmits information. Specifically, the receiver ID of the recording unit 25 of FIG. 1 is acquired, and the acquired receiver ID and the predictive time information acquired by SC2 of FIG. 5 are associated with each other, and the communication unit 21 of FIG. Is transmitted to the center device 3 via. Here, for example, the information of the set of "IDb1" and the set of "101030" in FIG. 2 to the information of the set of "101230" are transmitted in association with each other. On the other hand, the control unit 33 of the center device 3 receives the transmitted information via the communication unit 31, and records the received information in the recording unit 32 as center-side disaster prevention information. Here, for example, the information of the set of "101030" in FIG. 5 (that is, the information of the set of "IDb1", "IDa1", "3.6", and "101030") to the information of the set of "101230" is recorded. To do.

Returning to FIG. 5, in SC4 after determining that the predetermined sign has not been detected (NO in SC1), the acquisition unit 261 acquires the normal time information. Here, the "normal time information" is information to be acquired when no sign is detected. For example, in the disaster prevention information on the receiver side of FIG. 2, the latest 5 sets (specifically, the detection time information) are used. , Sensor ID, smoke concentration information, and detection time information), that is, the amount of information is smaller than the information for predictive time in SC2. The specific acquisition method in SC4 is arbitrary, but here, for example, the information storage process of FIG. 4 acquires the latest (that is, the latest) set of information regarding the detection time information as normal time information.

Returning to FIG. 5, in SC5, the transmission control unit 263 of the receiver 2 transmits information. Specifically, the receiver ID of the recording unit 25 of FIG. 1 is acquired, and the acquired receiver ID and the normal time information acquired by SC4 of FIG. 5 are associated with each other, and the communication unit 21 of FIG. 1 is associated with each other. Is transmitted to the center device 3 via. On the other hand, the control unit 33 of the center device 3 records the disaster prevention information on the center side in the same manner as in the case described in SC3. Then, the control unit 33 of the center device 3 grasps at least the state of the monitoring area (specifically, the smoke concentration) immediately before the fire occurs in real time based on the recorded disaster prevention information on the center side, thereby causing a fire. It predicts the occurrence and outputs a predictive alarm, which is an alarm that notifies that there is a sign of a fire. By outputting the sign alarm in this way, it is possible to carry out fire extinguishing activities before the occurrence of a fire is determined in the monitoring area (that is, before the fire spreads). This ends the information transmission process.

(About the amount of information)
When the information transmission process of FIG. 5 described above is repeatedly executed, the target information is transmitted regardless of whether or not the SC1 has detected a predetermined sign, and in particular, before the SC1 detects the predetermined sign. Sends normal time information (that is, one set of information) on the SC5, and after the SC1 detects a predetermined sign, sends the sign time information (that is, five sets of information) to the SC5. Since the information is transmitted, the amount of information transmitted per unit time before the detection of the predetermined sign is reduced, while the amount of information transmitted after the detection of the predetermined sign is increased by increasing the amount per unit time. The smoke concentration information after the sensor 1 transmits the pre-alarm can be transmitted with high resolution with respect to time, and the transmission amount can be suppressed as a whole. Therefore, the center device 3 manages the disaster prevention system 100 based on the transmitted information, grasps at least the state of the monitoring area immediately before the fire in detail in real time, and determines or predicts the occurrence of the fire. It becomes possible to do.

(Effect of embodiment)
As described above, according to the present embodiment, by transmitting the target information to the center device 3 based on the detection result of the detection unit 262 that detects a predetermined sign related to disaster prevention, for example, in relation to the predetermined sign. Since the target information can be transmitted, the information can be appropriately transmitted in relation to the event. In particular, for example, by increasing the transmission amount of the target information per unit time when a predetermined sign is detected, it is possible to transmit the data immediately before the event occurs in detail.

Further, by acquiring the management information which is the information for managing the disaster prevention system 100 as the target information, for example, the management information can be transmitted to the center device 3, so that the disaster prevention system 100 is on the center device 3 side. Can be managed.

Further, by detecting the sign of a fire in the monitoring area as a predetermined sign, for example, information related to the fire which is an event can be appropriately transmitted to the center device 3, so that the center device 3 can determine the fire. It can be predicted, and it is possible to improve the disaster prevention property against fire in the monitoring area.

Further, the amount of the target information transmitted to the center device 3 per unit time after detecting the predetermined sign is the target information transmitted to the center device 3 before detecting the predetermined sign. By transmitting the target information so as to be larger than the amount per unit time of, for example, while suppressing the transmission amount of the entire target information before and after the sign detection, at least immediately before the event occurs (that is, after the sign detection). Since it is possible to increase the transmission amount of the target information, it is possible to transmit the target information immediately before the event occurs in detail while suppressing the total communication amount of the target information.

Although the embodiments according to the present invention have been described above, the specific configuration and means of the present invention may be arbitrarily modified and improved within the scope of the technical idea of each invention described in the claims. Can be done. Hereinafter, such a modification will be described.

(About the problem to be solved and the effect of the invention)
First, the problem to be solved by the invention and the effect of the invention are not limited to the above-mentioned contents, and may differ depending on the implementation environment and the details of the configuration of the invention, and only a part of the above-mentioned problems. May be resolved or only some of the above effects may be achieved.

(About distribution and integration)
Further, the above-described configuration is a functional concept, and does not necessarily have to be physically configured as shown in the figure. That is, the specific form of dispersion or integration of each part is not limited to that shown in the figure, and all or a part thereof can be functionally or physically dispersed or integrated in any unit. The term "system" in the present application is not limited to a system composed of a plurality of devices, but includes a system composed of a single device. Further, the "device" in the present application is not limited to a device composed of a single device, but includes a device composed of a plurality of devices. For example, the functions of the acquisition unit 261 and the detection unit 262 of the receiver 2 and the transmission control unit 263 are provided in a device of the disaster prevention system 100 other than the receiver 2 (for example, a disaster prevention display device (not shown)). The device may be configured as a transmission system, or the functions of the acquisition unit 261 and the detection unit 262 of the receiver 2 and the transmission control unit 263 may be provided by a device other than the disaster prevention system 100 (for example, a stationary computer device). Alternatively, it may be provided in a mobile terminal such as a smartphone) to configure the device as a transmission system.

(About information storage processing)
Further, in the above embodiment, the case where the receiver 2 transmits the information request in the SA1 of FIG. 4 to acquire and store the information from the sensor 1 has been described, but the present invention is not limited to this. For example, the sensor 1 may be configured to automatically transmit information at an arbitrary timing, and the receiver 2 may receive and store the transmitted information. The arbitrary timing may be the timing for each arbitrarily set time (for example, 10 seconds to 30 seconds, etc.), or as described in SC1 of FIG. 5, the control unit 14 of the sensor 1 is conventionally used. Similarly to the above, the timing may be set to compare the concentration of smoke detected by the detection unit 12 with the fire caution threshold value and the fire determination threshold value of the recording unit 13.

(Processing by sensor)
Further, in the process of the control unit 14 of the sensor 1 described in SC1 of FIG. 5 of the above implementation, the concentration of smoke detected by the detection unit 12 is compared with the fire caution threshold value and the fire judgment threshold value of the recording unit 13. The process to be performed may be repeated every 5 to 10 seconds, for example, by narrowing the repetition interval so that the pre-alarm is output even when the smoke concentration rises sharply. Further, regarding this process, the pre-alarm may be configured to continue to output until the smoke concentration becomes less than the fire caution threshold, or after the smoke concentration becomes less than the fire caution threshold for a predetermined time (for example, The output may be continued until 2 minutes to 5 minutes, etc. have passed.

(About information transmission processing (1))
Further, in SC1 of FIG. 5 of the above-described embodiment, a case where a predetermined sign is determined based on whether or not a pre-alarm is received has been described, but the present invention is not limited to this. For example, the determination may be made in consideration of the alarm signal in addition to the pre-alarm. Specifically, when a pre-alarm or a warning signal is received, it is determined that a predetermined sign has been detected, and when both a pre-alarm and a warning signal are not received, a predetermined sign is detected. It may be determined that the signal is not provided. When configured in this way, the "predetermined sign" may be regarded as a sign of a fire or a sign of the spread of a fire. With this configuration, it is possible to transmit information until the smoke concentration continues to increase and the fire is determined, and information after the fire is determined with high time resolution.

(About information transmission processing (2))
Further, with respect to SC1 of FIG. 5, when the pre-alarm is continuously detected for a predetermined time (for example, 2 minutes or the like), it may be determined that a predetermined sign has been detected. With this configuration, it is possible to prevent the amount of information transmitted from increasing when a factor other than a fire (for example, steam temporarily generated during cooking) is erroneously detected as fire smoke. That is, it is possible to transmit information that actually leads to a fire with high time resolution.

(About information transmission processing (3))
In addition, contrary to "(Information transmission processing (2))", if information on the case where a factor other than fire is erroneously detected as fire smoke is particularly required, a pre-alarm is set for a predetermined time ( For example, when the detection is continued for 2 minutes or more, the execution interval of the information storage process in FIG. 4 is narrowed so that the receiver 2 stores the information at intervals of, for example, 5 seconds to 10 seconds. It may be configured to transmit all the information stored at narrow intervals to the center device 3.

(About information transmission processing (4))
Further, in the above embodiment, the case where the information transmitted per unit time is changed based on whether or not a predetermined sign is detected has been described, but the present invention is not limited to this. For example, the information may not be transmitted until a predetermined sign is detected, and the transmission of the information may be started when the predetermined sign is detected. Specifically, SC4 and SC5 may be omitted in FIG. 5, and SC1 may be configured to execute SC1 again after determining NO. With such a configuration, for example, by starting the transmission of the target information when a predetermined sign is detected, it is possible to start the transmission of the target information immediately before the event occurs.

(About communication network)
Further, for at least a part of the communication network between the receiver 2 and the center device 3 of FIG. 1 of the above embodiment, a new communication network other than the existing communication network of the user (for example, the customer) having the receiver 2 is used. A user (for example, a trader) on the center device 3 side may lay a communication network, and communication between the receiver 2 and the center device 3 may be performed using the newly laid communication network.

(About storage of target information)
Further, in the above embodiment, the case where the sensor ID, the receiver ID, the smoke concentration information, and the detection time information are transmitted to the center device 3 as the target information has been described, but the present invention is not limited to this. For example, any information among the information exemplified in the definition of "target information" (for example, appearance image information, current value information, etc.) is configured to be transmitted from the disaster prevention system 100 side to the center device 3 side. May be good.

Then, in the case of transmitting the appearance image information, the appearance of the receiver 2 is imaged using a mobile terminal such as a smartphone, and then the image captured by the mobile terminal is indirectly transmitted via the receiver 2. Alternatively, it may be configured to transmit directly to the center device 3 without going through the receiver 2. When configured in this way, the mobile terminal may also be regarded as an element of the transmission system.

Further, in the current value information, the receiver 2 accesses an electric device for power supply (for example, a breaker device or the like), acquires the current value of the power supply supplied to the receiver 2, and acquires the acquired current. The value information may be configured to be transmitted to the center device 3 as current value information. With such a configuration, it is possible for the center device 3 side to grasp an abnormality of the power supply supplied to the receiver 2 (for example, supply of overcurrent).

(About sending target information)
Further, in the above embodiment, the case where the time resolution of the information to be transmitted is changed based on the detection result of a predetermined sign has been described, but the present invention is not limited to this. For example, the number of items of information to be transmitted may be changed based on the detection result of a predetermined sign. Specifically, the number of information items transmitted at one time when a predetermined sign is detected is larger than the number of information items transmitted at one time when a predetermined sign is not detected. It may be configured to be, or vice versa. For example, various information such as display contents, operations, alarms, and settings of the receiver 2 may be transmitted. As a result, it becomes possible for the center device 3 side to grasp what kind of response has been taken by the receiver 2, including the behavior of the operator. Further, it may be arranged in the disaster prevention system 100, display the same as that of the receiver 2, and transmit the information of the sub-display panel that accepts the operation.

(Change of information update frequency)
Further, in the above embodiment, the amount of information transmitted by the disaster prevention system 100 is changed, but the communication frequency of the disaster prevention system 100 may be changed. For example, when the disaster prevention system 100 detects a predetermined sign, the disaster prevention system 100 transmits the sign detection to the center device 3, and the center device 3 narrows the communication interval with respect to the disaster prevention system 100 that has received the sign detection. Good.

(Change in the amount of information per unit time)
Further, in the above embodiment, the amount of information per unit time at the time of detecting a sign is increased, but when a plurality of disaster prevention systems such as the disaster prevention system 100 are provided, any of the disaster prevention systems is used for the sign. When is detected, the amount of information per unit time from the disaster prevention system that does not detect the sign may be reduced. For example, when a sign is detected by a predetermined disaster prevention system (hereinafter referred to as "disaster prevention system A"), the disaster prevention system A transmits the sign detection to the center device 3, and the center device 3 sends the sign detection to all the disaster prevention systems. , A disaster prevention system that sends a sign detection by one of the disaster prevention systems and receives a sign detection by one of the disaster prevention systems that does not detect a sign by itself (that is, among multiple disaster prevention systems) Disaster prevention systems other than the disaster prevention system A) may reduce the amount of information per unit time. With such a configuration, the amount of communication between the center device 3 and the plurality of disaster prevention systems can be kept constant, so that the possibility of problems such as congestion can be reduced.

(About the use of target information)
Further, in the above embodiment, the case where the state of the monitoring area is grasped on the center device 3 side by using the transmitted target information has been described, but the present invention is not limited to this. For example, even if any information among the information exemplified in the definition of "target information" is used to specify a replacement part for failure countermeasures for each device of the disaster prevention system 100 on the center device 3 side. You may instruct maintenance or operation, or you may modify the program for determining the occurrence of a fire in the sensor 1.

(About the transmission control unit with transmission start function)
Further, instead of the transmission control unit 263 of the above embodiment, or in addition to the transmission control unit 263, a transmission control unit with a transmission start function may be provided in the control unit 26 of the receiver 2. Here, the "transmission control unit with transmission start function" is a means for transmitting the target information acquired by the acquisition means to the center device based on the detection result of the detection means. For example, the detection means is a predetermined sign. When the transmission of the target information is started when the detection means is detected, and when the detection means detects the sign after starting the transmission of the target information regardless of whether or not the detection means has detected a predetermined sign, per unit time. It is a concept including one that changes (for example, increases or decreases) the amount of target information transmitted to. At least a part of the functions of the transmission control unit with the transmission start function may be implemented in the transmission control unit 263.

(About features)
Further, the features of the above-described embodiment and the features of the modified example may be arbitrarily combined.

(Additional note)
The transmission system of Appendix 1 is a center device that collects the target information of the disaster prevention system, which is information about the disaster prevention system in the monitoring area, and is different from the disaster prevention system. It is a transmission system that transmits to the device, and the acquisition means for acquiring the target information, the detection means for detecting a predetermined sign related to disaster prevention, and the target information acquired by the acquisition means are related to the detection result of the detection means. The transmission control means for transmitting to the center device, the transmission control means for changing the transmission mode of the target information based on the detection result of the detection means.

In the transmission system described in Appendix 1, the acquisition means acquires management information, which is information for managing the disaster prevention system on the center device side, as the target information.

In the transmission system according to Appendix 1 or 2, the detection means detects a sign of fire in the monitoring area as the predetermined sign.

The transmission system of Supplementary note 4 is the transmission system according to any one of Supplementary note 1 to 3, wherein the transmission control means transmits to the center device after the detection means detects the predetermined sign. The amount of the target information to be generated per unit time is greater than the amount of the target information transmitted to the center device per unit time before the detection means detects the predetermined sign. The target information acquired by the acquisition means is transmitted to the center device.

(Effect of appendix)
According to the transmission system described in Appendix 1, the target information is transmitted to the center device based on the detection result of the detection means for detecting a predetermined sign related to disaster prevention, so that, for example, the target information is related to the predetermined sign. Can be sent, so information related to the event can be sent appropriately. In particular, for example, by increasing the transmission amount of the target information per unit time when a predetermined sign is detected, it is possible to transmit the data immediately before the event occurs in detail.

According to the transmission system described in Appendix 2, by acquiring the management information, which is the information for managing the disaster prevention system, as the target information, for example, the management information can be transmitted to the center device. It becomes possible to manage the disaster prevention system on the device side.

According to the transmission system described in Appendix 3, by detecting the sign of a fire in the monitoring area as a predetermined sign, for example, information related to the fire that is an event can be appropriately transmitted to the center device. It is possible to judge and predict a fire on the side, and it is possible to improve the disaster prevention property against a fire in the monitoring area.

According to the transmission system described in Appendix 4, the amount of target information transmitted to the center device per unit time after detecting the predetermined sign is the center device before the predetermined sign is detected. By transmitting the target information so as to be larger than the amount of the target information transmitted per unit time, for example, while suppressing the transmission amount of the entire target information before and after the sign detection, at least immediately before the event occurs. Since the transmission amount (that is, after the sign is detected) can be increased, it is possible to transmit the target information immediately before the event occurrence in detail while suppressing the total communication amount of the target information.
