[0011] Hereinafter, the embodiments will be described in detail with reference to the drawings. Note that the embodiments described below are all comprehensive or specific examples. The numerical values, shapes, materials, components, component arrangement and connection forms, steps, and order of steps shown in the following embodiments are merely examples and are not intended to limit the present invention. In addition, among the components in the following embodiments, components that are not described in the independent claims will be described as optional components.

[0012] In addition, each drawing is a schematic diagram and is not necessarily a precise illustration. In each drawing, the same reference numerals are used for substantially the same configurations, and duplicated explanations may be omitted or simplified.

[0013] (Embodiment) [composition] The configuration of the construction work support system according to the embodiment will be described below. Fig. 1 is a block diagram showing the functional configuration of the construction work support system according to the embodiment.

[0014] The construction work support system 10 shown in Fig. 1 is a system that can provide information for supporting construction work (hereinafter also referred to as support information) based on the sensing results of sensors equipped in multiple fire alarms 20 installed at a construction site 90. The construction site 90 is a location where a building is in the process of being constructed, and in the following description, the construction site 90 is described as being the interior of a building in the process of being constructed. The building here is, for example, an apartment building, a factory, a research facility, a medical facility, or an accommodation facility, but is not limited to such a building.

[0015] The construction work support system 10 comprises a plurality of fire alarms 20, a repeater 30, a base station 40, a server device 50, a weather information distribution server 60, and an information terminal 70. It is sufficient that the construction work support system 10 comprises at least one fire alarm 20. The construction work support system 10 comprises one repeater 30 for the plurality of fire alarms 20, but the construction work support system 10 may comprise a plurality of repeaters 30 for the plurality of fire alarms 20, for example, a plurality of repeaters 30 in one-to-one correspondence with the plurality of fire alarms 20.

[0016] The fire alarm 20 is temporarily installed at a construction site 90 (specifically, a building under construction, etc.) to detect the occurrence of a fire at the construction site 90 at least until the building is completed. The fire alarm 20 includes a smoke sensor 21, an environmental sensor 22, a communication unit 23, a control unit 24, a storage unit 25, an alarm unit 26, and a housing 27.

[0017] The smoke sensor 21 is a sensor for detecting the occurrence of a fire at the construction site 90. The smoke sensor 21 includes a light-emitting element such as a light-emitting diode, and a light-receiving element such as a photodiode. In the smoke sensor 21, the light emitted by the light-emitting element is scattered by smoke particles and enters the light-receiving element, and the smoke sensor 21 can detect the occurrence of smoke based on the amount of light entering the light-receiving element.

[0018] The fire alarm 20 may include a heat sensor (temperature sensor) instead of the smoke sensor 21 or in addition to the smoke sensor 21. The heat sensor is another example of a sensor for detecting the occurrence of a fire.

[0019] The environmental sensor 22 senses the environment at the construction site 90. Specifically, the environmental sensor 22 is a temperature sensor, a humidity sensor, a dust sensor (in other words, a dust sensor or a particulate concentration sensor), an image sensor (in other words, a camera), a carbon dioxide concentration sensor, or the like. That is, the environmental sensor 22 senses the temperature, humidity, amount of dust generated (generation level), images, carbon dioxide concentration, or the like at the construction site 90. The fire alarm 20 may be equipped with multiple types of environmental sensors 22.

[0020] If the fire alarm 20 is equipped with a smoke sensor 21, the smoke sensor 21 can also sense the level of dust generation at the construction site 90. Since dust subsides in a relatively short period of time after generation, whereas smoke caused by a fire continues to be generated for a relatively long period of time, the control unit 24 can distinguish between smoke and dust by processing the output signal of the smoke sensor 21.

[0021] Furthermore, if the fire alarm 20 is equipped with a heat sensor, it is also possible to sense the temperature of the construction site 90 by the heat sensor. In this manner, the distinction between the sensor for detecting the outbreak of a fire and the environmental sensor 22 is made for the sake of convenience, and it is also possible to sense the environment at the construction site 90 by the sensor for detecting the outbreak of a fire.

[0022] The communication unit 23 is a communication circuit for the fire alarm device 20 to communicate with the server device 50 via the repeater 30 and the base station 40. The communication unit 23 is, for example, a wireless communication circuit that performs wireless communication with the repeater 30. The communication standard of the communication performed by the communication unit 23 is not particularly limited.

[0023] When the smoke sensor 21 detects the occurrence of a fire, the control unit 24 activates the alarm unit 26 to alert people located at the construction site 90. When the smoke sensor 21 detects the occurrence of a fire, the control unit 24 notifies the user of the information terminal 70 of the occurrence of a fire by transmitting notification information to the server device 50 using the communication unit 23. The control unit 24 is realized, for example, by a microcomputer, but may also be realized by a processor. The functions of the control unit 24 are realized, for example, by the microcomputer or processor constituting the control unit 24 executing a computer program stored in the storage unit 25.

[0024] The storage unit 25 is a storage device that stores computer programs and the like executed by the control unit 24. The storage unit 25 is realized by, for example, a semiconductor memory.

[0025] The notification unit 26 issues a notification to people located at the construction site 90 when a fire is detected by the smoke sensor 21. The notification unit 26 is realized by, for example, at least one of a speaker and a light-emitting element, and issues a notification by at least one of sound and light.

[0026] The housing 27 accommodates the smoke sensor 21, the environmental sensor 22, the communication unit 23, the control unit 24, the storage unit 25, and the notification unit 26. The housing 27 is formed of, for example, a resin material.

[0027] The repeater 30 is a gateway device that enables the fire alarm device 20 to communicate with the base station 40. In other words, the repeater 30 is a device that enables the fire alarm device 20 to communicate with the server device 50 through a mobile communication network. The repeater 30 is temporarily installed, for example, at a construction site 90. The base station 40 is a base station of the mobile communication network, and is located, for example, outside the construction site 90.

[0028] The server device 50 notifies the information terminal 70 of the occurrence of a fire based on the notification information received from the fire alarm 20. The server device 50 also provides information for supporting construction work to the information terminal 70 based on the sensing results of the environmental sensors 22 provided in the multiple fire alarms 20 installed at the construction site 90. The server device 50 includes a communication unit 51, an information processing unit 52, and a storage unit 53.

[0029] The communication unit 51 is a communication circuit for the server device 50 to communicate with the fire alarm 20, the weather information distribution server 60, and the information terminal 70. The communication unit 51 is, for example, a wired communication circuit for performing wired communication, but may also be a wireless communication circuit for performing wireless communication. The communication standard of the communication performed by the communication unit 51 is not particularly limited.

[0030] The information processing unit 52 processes information regarding notification of a fire outbreak and provision of information to support construction work. The information processing unit 52 is realized, for example, by a microcomputer, but may also be realized by a processor. The information processing unit 52 includes an acquisition unit 54 and an output unit 55 as functional components. The functions of the acquisition unit 54 and the output unit 55 are realized, for example, by the microcomputer or processor constituting the information processing unit 52 executing a computer program stored in the storage unit 53.

[0031] The storage unit 53 is a storage device that stores computer programs and the like executed by the information processing unit 52. The storage unit 53 is realized by, for example, a semiconductor memory.

[0032] The weather information distribution server 60 is a cloud server that distributes environmental information indicating the weather, temperature, and humidity of the area to which the construction site 90 belongs (i.e., the weather, temperature, and humidity around the construction site 90) to the server device 50. The weather information distribution server 60 can communicate with the server device 50 via a wide area communication network such as the Internet.

[0033] The information terminal 70 is a portable information terminal such as a personal computer, a tablet terminal, or a smartphone. The information terminal 70 is used by a user to receive a notification of a fire occurring at the construction site 90 and information for supporting the construction work. The user of the information terminal 70 may be a worker working at the construction site 90, or a manager managing the workers. In FIG. 1, the information terminal 70 is located outside the construction site 90, but when the user of the information terminal 70 is a worker, the information terminal 70 is located at the construction site 90.

[0034] The information terminal 70 includes a display unit 71 that displays an image (display screen). The display unit 71 is realized by a display panel such as a liquid crystal panel or an organic EL panel.

[0035] [Fire outbreak warning] First, a description will be given of the operation of notifying the occurrence of a fire in the construction work support system 10. Fig. 2 is a sequence diagram of the operation of notifying the occurrence of a fire in the construction work support system 10.

[0036] When the smoke sensor 21 of the fire alarm 20 detects the occurrence of a fire (S11), the control unit 24 activates the notification unit 26 to notify the occurrence of a fire to workers located at the construction site 90 (S12). The notification to the workers is performed by at least one of sound and light.

[0037] In addition, control unit 24 uses communication unit 23 to transmit the notification information to server device 50 (S13). Although not shown in detail in FIG. 2, the notification information is transmitted to server device 50 via relay 30 and base station 40.

[0038] The communication unit 51 of the server device 50 receives the notification information. The output unit 55 uses the communication unit 51 to output (transmit) the received notification information to the information terminal 70 that has been registered in advance (S14).

[0039] The information terminal 70 receives the notification information, and based on the received notification information, displays a notification screen for notifying that a fire has broken out at the construction site 90 on the display unit 71 provided in the information terminal 70 (S15). Fig. 3 is a diagram showing an example of the notification screen. In addition to displaying the notification screen, the information terminal 70 may output a notification sound for notifying that a fire has broken out at the construction site 90 from a speaker (not shown) provided in the information terminal 70.

[0040] The storage unit 53 of the server device 50 stores information associating the identification information of the fire alarm 20 with information relating to the installation location of the fire alarm 20. If the information relating to the installation location includes the name of a building under construction at the construction site 90, the name of the building in which the fire occurred can be displayed on the notification screen as shown in Fig. 3. Although not shown, if the information relating to the installation location includes information regarding the floor on which the fire alarm 20 is installed and the area (district) to which the construction site 90 belongs, the floor on which the fire occurred and the area in which the fire occurred can be displayed on the notification screen.

[0041] Furthermore, if the information regarding the installation location includes information indicating the coordinates (e.g., latitude and longitude) of the construction site 90, it is possible to display a map on the notification screen and then indicate the location of the fire on the map. In this case, for example, at least one of the server device 50 and the information terminal 70 communicates with a server device (not shown) that manages map information, thereby acquiring map information for displaying the map on the notification screen.

[0042] In this way, by temporarily installing a fire alarm 20 at the construction site 90, the construction work support system 10 can notify workers located at the construction site 90 of the occurrence of a fire at the construction site 90 and also notify the user of the information terminal 70.

[0043] [Providing comfort information based on environmental information] The construction work support system 10 can provide information for supporting construction work to the user of the information terminal 70 by utilizing the mechanism of the above-mentioned fire occurrence notification operation. The information for supporting construction work is, for example, comfort information indicating whether the environment of the construction site 90 is suitable for work (whether the environment is comfortable for workers). The operation of providing such comfort information will be described below. Fig. 4 is a sequence diagram of the operation of providing comfort information.

[0044] The control unit 24 of the fire alarm 20 uses the communication unit 23 to transmit environmental information sensed by the environmental sensor 22 to the server device 50 (S21). Although not shown in detail in Fig. 4, the environmental information is transmitted to the server device 50 via the repeater 30 and the base station 40. Also, although not shown in detail in Fig. 4, the transmission of the environmental information from the fire alarm 20 to the server device 50 is performed periodically, for example, at predetermined time intervals.

[0045] The environmental information may be sensed by a sensor for detecting a fire (the smoke sensor 21 or the heat sensor) and transmitted to the server device 50. As described above, the smoke sensor 21 can sense the generation of dust, and the heat sensor can sense the temperature.

[0046] The communication unit 51 of the server device 50 receives the environmental information. The acquisition unit 54 acquires the environmental information received by the communication unit 51 (S22), and the output unit 55 judges whether or not the construction site 90 is an environment suitable for work based on the acquired environmental information (S23). FIG. 5 is a diagram showing an example of a criterion for judging whether or not the construction site 90 is an environment suitable for work. Note that, while FIG. 5 shows an example of a criterion for a case where the judgment is made in three stages, the judgment may be made in two stages, or may be made in four or more stages in detail. The threshold value used for the judgment is also an example, and is not particularly limited.

[0047] 5(a), for example, when the environmental information indicates the temperature of the construction site 90, the output unit 55 determines that the construction site 90 is an uncomfortable environment unsuitable for work when the temperature is 30° C. or higher, and determines that the construction site 90 is an ordinary environment when the temperature is higher than 20° C. and lower than 30° C. The output unit 55 determines that the construction site 90 is a comfortable environment suitable for work when the temperature is 20° C. or lower.

[0048] 5(b), when the environmental information indicates the humidity of the construction site 90, the output unit 55 determines that the construction site 90 is an uncomfortable environment unsuitable for work when the humidity is 60% or higher, and determines that the construction site 90 is an ordinary environment when the humidity is higher than 40% and lower than 60%. When the humidity is 40% or lower, the output unit 55 determines that the construction site 90 is a comfortable environment suitable for work.

[0049] 5(c), when the environmental information indicates the dust generation level (amount of generation) at the construction site 90, the output unit 55 determines that the construction site 90 is an uncomfortable environment unsuitable for work when the dust generation level is high, and determines that the construction site 90 is an ordinary environment when the dust generation level is medium. When the dust generation level is low, the output unit 55 determines that the construction site 90 is a comfortable environment suitable for work.

[0050] Next, the output unit 55 outputs (transmits) comfort information indicating the determination result to the information terminal 70 using the communication unit 51 (S24). The information terminal 70 receives the comfort information, and displays a display screen indicating the comfort of the construction site 90 on the display unit 71 provided in the information terminal 70 based on the received comfort information (S25). Fig. 6 is a diagram showing an example of a display screen indicating the comfort of the construction site 90.

[0051] In this way, the construction work support system 10 can provide comfort information indicating whether the environment of the construction site 90 is suitable for work to the user of the information terminal 70 by utilizing the mechanism of the fire occurrence notification operation. Since the environment of the construction site 90 is generally worse than the environment inside the building after the building is completed, the comfort information at the construction site 90 can be said to be very useful information.

[0052] The output unit 55 may output comfort information based on multiple types of environmental information (such as temperature and humidity). For example, the output unit 55 calculates a first evaluation value, which indicates a higher value as the environment is worse, based on the first environmental information, and calculates a second evaluation value, which indicates a higher value as the environment is worse, based on the second environmental information. The output unit 55 can determine whether the construction site 90 is an uncomfortable environment, a normal environment, or a comfortable environment by comparing a comprehensive evaluation value obtained by adding up the first evaluation value and the second evaluation value with a predetermined threshold value.

[0053] [Providing comfort information based on dirt information] In the above-described operation of providing comfort information, the fire alarm 20 may transmit dirt information of the smoke sensor 21 instead of environmental information to the server device 50. For example, the control unit 24 of the fire alarm 20 may use the communication unit 23 to determine the dirt level of the smoke sensor 21, and transmit the dirt information indicating the dirt level to the server device 50 in step S21.

[0054] As described above, in the smoke sensor 21, the light emitted by the light-emitting element is scattered by smoke particles and enters the light-receiving element. When dirt occurs, the amount of light entering the light-receiving element in a state where no smoke is generated gradually increases. In other words, the base value of the voltage output from the light-receiving element increases. The control unit 24 can determine the dirt level based on the base value. The dirt level is classified into three stages, for example, high level (high base value and much dirt), medium level, and low level (low base value and little dirt), but may be classified into two stages or may be classified into four or more stages.

[0055] In this way, when dirt information is transmitted from the fire alarm 20 to the server device 50, in step S22, the acquisition unit 54 acquires the dirt information received by the communication unit 51, and in step S23, the output unit 55 determines whether or not the construction site 90 is an environment suitable for work based on the acquired dirt information.

[0056] 5(d), when the dirt level indicated by the dirt information is high, the output unit 55 determines that the construction site 90 is an uncomfortable environment unsuitable for work, and when the dirt level indicated by the dirt information is medium, the output unit 55 determines that the construction site 90 is an ordinary environment. When the dirt level indicated by the dirt information is low, the output unit 55 determines that the construction site 90 is a comfortable environment suitable for work.

[0057] In this way, the construction work support system 10 can provide the user of the information terminal 70 with comfort information indicating whether the environment of the construction site 90 is suitable for work, based on the dirt information.

[0058] The output unit 55 may output the comfort information based on both the environmental information and the dirt information. For example, the output unit 55 calculates an environmental evaluation value that indicates a higher value the worse the environment is based on the environmental information, and calculates a dirt evaluation value that indicates a higher value the more dirty the environment is based on the dirt information. The output unit 55 can determine whether the construction site 90 is an uncomfortable environment, a normal environment, or a comfortable environment by comparing a total evaluation value obtained by adding up the environmental evaluation value and the dirt evaluation value with a predetermined threshold value.

[0059] [Providing information about heat stroke] In the above-mentioned operation of providing comfort information, the output unit 55 of the server device 50 judges whether the construction site 90 is an environment suitable for work or not, but may also judge the risk of heat stroke. FIG. 7 is a diagram showing an example of a judgment criterion for judging the risk of heat stroke. Note that FIG. 7 shows an example of a judgment criterion when the judgment is made in three stages, but the judgment may be made in two stages, or may be made in four or more stages in detail. The threshold value used for the judgment is also an example, and is not particularly limited.

[0060] 7(a), for example, when the environmental information indicates the temperature of the construction site 90, the output unit 55 determines that the construction site 90 is an environment with a high risk of heat stroke if the temperature is 35° C. or higher, and determines that the construction site 90 is an environment with a normal risk of heat stroke if the temperature is higher than 28° C. and lower than 35° C. The output unit 55 determines that the construction site 90 is an environment with a low risk of heat stroke if the temperature is 28° C. or lower.

[0061] 7(b), when the environmental information indicates the humidity of the construction site 90, the output unit 55 determines that the construction site 90 is an environment with a high risk of heat stroke when the humidity is 65% or higher, and determines that the construction site 90 is an environment with a normal risk of heat stroke when the humidity is higher than 40% and lower than 65%. The output unit 55 determines that the construction site 90 is an environment with a low risk of heat stroke when the humidity is 40% or lower.

[0062] Furthermore, the communication unit 51 of the server device 50 may receive environmental information indicating the weather in the area to which the construction site 90 belongs from the weather information distribution server 60 instead of the fire alarm 20, and the acquisition unit 54 may acquire the environmental information indicating the weather. In this case, the environmental information is, for example, information indicating the weather in the area to which the construction site 90 belongs.

[0063] 7(c), when the weather in the area to which the construction site 90 belongs is sunny, the output unit 55 determines that the construction site 90 is in an environment with a high risk of heatstroke, and when the weather in the area to which the construction site 90 belongs is cloudy, the output unit 55 determines that the construction site 90 is in an environment with a normal risk of heatstroke. When the weather in the area to which the construction site 90 belongs is rainy, the output unit 55 determines that the construction site 90 is in an environment with a low risk of heatstroke.

[0064] In this way, when the risk of heat stroke is determined in step S23, in step S24, the output unit 55 outputs (transmits) heat stroke information, and in step S25, a display screen indicating the risk of heat stroke is displayed on the display unit 71 of the information terminal 70. Fig. 8 is a diagram showing an example of a display screen indicating the risk of heat stroke.

[0065] In this way, the construction work support system 10 can provide the user of the information terminal 70 with heat stroke information indicating whether or not the environment of the construction site 90 is an environment with a high risk of heat stroke, based on the environmental information.

[0066] The output unit 55 may output heat stroke information based on multiple types of environmental information (such as temperature and humidity). For example, the output unit 55 calculates a first evaluation value based on the first environmental information, the higher the risk of heat stroke, and calculates a second evaluation value based on the second environmental information, the higher the risk of heat stroke. The output unit 55 can determine whether the construction site 90 is an environment with a high risk of heat stroke, an average environment, or an environment with a low risk of heat stroke by comparing a comprehensive evaluation value obtained by adding up the first evaluation value and the second evaluation value with a predetermined threshold value.

[0067] Furthermore, the output unit 55 may transmit alert information to the information terminal 70, which prompts workers to take measures against heat stroke, such as taking a break, when a situation in which the risk of heat stroke is determined to be high continues for a certain period of time or more. In other words, the output unit 55 may output information that prompts workers (people) to stop working when a state in which the construction site 90 is unsuitable for work continues for a certain period of time or more. The certain period of time is, for example, about 30 minutes to 1 hour, and may be appropriately determined empirically or experimentally by the designer or manager of the construction work support system 10.

[0068] [Providing false information] In the above operation of providing comfort information, the output unit 55 of the server device 50 judges whether the construction site 90 is an environment suitable for work or not, but may also judge the likelihood of false alarms from the fire alarm 20. FIG. 9 is a diagram showing an example of a judgment criterion for judging the likelihood of false alarms. Note that, while FIG. 9 shows an example of a judgment criterion when the judgment is made in three stages, the judgment may be made in two stages, or may be made in four or more stages in detail. The threshold values ​​used for the judgment are also merely an example, and are not particularly limited.

[0069] 9(a), for example, when the acquisition unit 54 acquires dirt information, the output unit 55 determines that the construction site 90 is an environment where a false alarm is likely to occur if the dirt level indicated by the dirt information is high, and determines that the construction site 90 is an environment where a false alarm is likely to occur if the dirt level indicated by the dirt information is medium. The output unit 55 determines that the construction site 90 is an environment where a false alarm is unlikely to occur if the dirt level indicated by the dirt information is low.

[0070] 9(b), when the acquisition unit 54 acquires environmental information indicating the dust generation level, the output unit 55 determines that the construction site 90 is an environment in which false alarms are likely to occur if the dust generation level is high, and determines that the construction site 90 is an environment in which false alarms are likely to occur if the dust generation level is medium. When the dust generation level is low, the output unit 55 determines that the construction site 90 is an environment in which false alarms are unlikely to occur.

[0071] In this way, when the likelihood of a false alarm occurring of the fire alarm 20 is determined in step S23, the output unit 55 outputs (transmits) false alarm information in step S24. As a result, in step S25, a display screen indicating the likelihood of a false alarm occurring is displayed on the display unit 71 of the information terminal 70. Fig. 10 is a diagram showing an example of a display screen indicating the likelihood of a false alarm occurring.

[0072] 10, the display screen may include a message encouraging the user to manually change the settings of the fire alarm 20 (changing the threshold for the smoke sensor 21). The display screen may also display a button for instructing the user to change the threshold so that the user can easily change the threshold. If the contamination information indicates a high contamination level, the display screen may also include a message encouraging maintenance of the fire alarm 20. Maintenance of the fire alarm 20 includes replacement of the fire alarm 20, replacement of parts (batteries, etc.) of the fire alarm 20, inspection of the fire alarm 20, etc.

[0073] The display screen may display detailed information about devices that are likely to cause false alarms. The detailed information includes information such as the device name and information about the location where the device is installed. Devices that are likely to cause false alarms include not only the fire alarm 20 that transmitted the environmental information in step S21, but also other devices (such as other fire alarms 20) installed in the vicinity (same area).

[0074] For example, if detailed information about the devices is stored (managed) in the memory unit 53 of the server device 50, the information processing unit 52 can determine that the fire alarm 20 that transmitted environmental information in step S21 and the devices installed within a specified range around it are devices that are prone to generating false alarms, and display detailed information about the devices that are considered to be prone to generating false alarms on the display screen.

[0075] When it is determined that there are multiple devices that are likely to generate false alarms, the multiple devices may be displayed in a list on the display screen. In this case, the order of the list display may be rearranged by device type.

[0076] Furthermore, if the information on the installation location includes information indicating the coordinates (e.g., latitude and longitude) of the installation location of the device, a map can be displayed on the display screen, and the location of the device that is considered to be prone to false reports can be shown on the map. In this case, for example, at least one of the server device 50 and the information terminal 70 communicates with a server device (not shown) that manages map information, thereby acquiring map information for displaying the map on the display screen.

[0077] In this way, the construction work support system 10 can provide the user of the information terminal 70 with false alarm information indicating whether the environment of the construction site 90 is an environment in which false alarms from the fire alarm 20 are likely to occur, based on environmental information or dirt information.

[0078] When the output unit 55 determines that the construction site 90 is an environment in which false alarms are likely to occur, it may use the communication unit 51 to output (transmit) threshold change command information to the fire alarm 20, thereby commanding the fire alarm 20 to change the threshold for the smoke sensor 21. The fire alarm 20 that receives the threshold change command information changes the threshold so that an alarm of a fire is less likely to occur. In other words, the server device 50 can suppress the occurrence of false alarms.

[0079] Furthermore, when a situation in which the construction site 90 is determined to be an environment in which false alarms are likely to occur continues for a certain period of time or more, the output unit 55 may cause the fire alarm 20 to perform an operation test by outputting (transmitting) a command to cause the fire alarm 20 to perform an operation test. The certain period of time is, for example, a period of several days to one week, but may be appropriately determined empirically or experimentally by the designer or manager of the construction work support system 10.

[0080] [Provision of maintenance information] The output unit 55 may output information related to the maintenance of the equipment installed at the construction site 90. Specifically, the information related to the maintenance is information indicating the replacement time of the equipment or consumables attached to the equipment, or information indicating the time to perform maintenance work or inspection work on the equipment. The equipment here is, for example, a fire alarm 20, but may also be an environmental sensor 61 (various sensors exemplified as the environmental sensor 61) or other equipment installed at the construction site 90.

[0081] For example, in the above-mentioned operation of providing comfort information, the output unit 55 judges the dust generation level based on the environmental information. For example, the output unit 55 accumulates the time during which the dust generation level is judged to be medium or high, and when the accumulated time reaches a predetermined value, the output unit 55 outputs (transmits) information related to maintenance to the information terminal 70 using the communication unit 51. The predetermined value is determined in advance based on the type of device and the contents of maintenance, and is stored in the storage unit 53.

[0082] The information terminal 70 receives the information regarding maintenance, and based on the received information regarding maintenance, displays a display screen indicating the maintenance timing on the display unit 71 provided in the information terminal 70. Fig. 11 is a diagram showing an example of the display screen indicating the maintenance timing.

[0083] In the example of Fig. 11, the display screen shows the future maintenance date, but if it is determined that immediate maintenance is required (if the maintenance date has passed), a message such as "Maintenance is required now" is displayed. Also, if a notification is received that it is time to replace a device or a device consumable, a message such as "Device replacement is required in one month" is displayed on the display screen.

[0084] The display screen may display detailed information about the device requiring maintenance, including at least one of the device name and information about the location where the device is installed.

[0085] For example, if the memory unit 53 of the server device 50 stores information that associates the identification information of a fire alarm 20 with detailed information of an appliance for which the need for maintenance is managed by the fire alarm 20, it is possible to display detailed information of the appliance requiring maintenance on the display screen.

[0086] Furthermore, when the need for maintenance of multiple devices is managed by the fire alarm 20, the multiple devices may be displayed in a list on the display screen. In this case, the order of the list display may be rearranged according to the type of device. Furthermore, when the predetermined value for the above-mentioned accumulated time differs for each device, the time when maintenance is required differs for each device. In such a case, the order of the list display may be rearranged according to the time when maintenance is required.

[0087] Furthermore, if the information on the installation location includes information indicating the coordinates (e.g., latitude and longitude) of the installation location of the device, a map can be displayed on the display screen and the location of the device requiring maintenance can be indicated on the map. In this case, for example, at least one of the server device 50 and the information terminal 70 communicates with a server device (not shown) that manages map information to obtain map information for displaying the map on the display screen.

[0088] The output unit 55 may output information related to maintenance using the result of the dirt level determination based on the dirt information instead of the result of the dust generation level determination based on the environmental information. In this case, the output unit 55, for example, accumulates the time during which the dirt level is determined to be medium or high, and outputs (transmits) the information related to maintenance to the information terminal 70 using the communication unit 51 when the accumulated time reaches a predetermined value.

[0089] Furthermore, the output unit 55 may output information related to maintenance using a combination of the determination result of the dust generation level based on the environmental information and the determination result of the dirt level based on the dirt information. The output unit 55, for example, accumulates a first time during which the dust generation level is determined to be medium or high, and a second time during which the dirt level is determined to be medium or high, and outputs (transmits) the information related to maintenance to the information terminal 70 using the communication unit 51 when the accumulated time reaches a predetermined value.

[0090] In this way, the construction work support system 10 can provide the user of the information terminal 70 with information regarding the maintenance of the equipment installed at the construction site 90 based on at least one of the environmental information and the dirt information.

[0091] In addition to the dust generation level, the environmental information for outputting the maintenance-related information may also include temperature, humidity, or weather. This is because, in general, equipment is more likely to deteriorate in a hot and humid environment, leading to an increased failure rate. Therefore, the output unit 55 may accumulate the time during which the temperature, humidity, and weather satisfy certain conditions that are considered to promote the deterioration of the equipment, and output (transmit) the maintenance-related information to the information terminal 70 using the communication unit 51 when the accumulated time reaches a certain value.

[0092] [Variations] The functional configuration of the construction work support system 10 described in the above embodiment is an example. For example, if the communication unit 23 of the fire alarm 20 is a communication circuit that can communicate with the base station 40 without the repeater 30, the construction work support system 10 does not need to include the repeater 30. FIG. 12 is a block diagram showing the functional configuration of the construction work support system 10 that does not include the repeater 30.

[0093] Furthermore, in the above embodiment, the acquisition unit 54 acquired environmental information from a sensor equipped in the fire alarm 20 or from the weather information distribution server 60, but the acquisition unit 54 may also acquire environmental information from a sensor set up at the construction site 90 that is not equipped in the fire alarm 20, or may acquire environmental information from a server other than the weather information distribution server 60.

[0094] Furthermore, in the above embodiment, the comfort information, heat stroke information, and false alarm information are output regardless of whether the judgment result is good or bad, but they may be output only when the judgment result indicates a bad state. For example, the comfort information is output only when the construction site 90 is judged to be an uncomfortable environment, and may not be output when the construction site 90 is judged to be a normal environment or a comfortable environment. As a result, the display unit 71 of the information terminal 70 displays a display screen indicating that the construction site 90 is an uncomfortable environment only when the construction site 90 is judged to be an uncomfortable environment.

[0095] Furthermore, in the above embodiment, when the server device 50 determines, based on the environmental information, that the construction site 90 is an environment in which false alarms are likely to occur, the server device 50 changes the threshold value for the output signal of the smoke sensor 21 of the fire alarm 20. In other words, the algorithm for detecting a fire using the smoke sensor 21 is changed. The server device 50 may also change detection algorithms using other sensors based on the environmental information.

[0096] For example, when a security sensor that issues an alarm when it detects infrared rays emitted from an intruder's body at night or the like is installed at the construction site 90, the server device 50 may change the detection algorithm using the security sensor based on the environmental information. For example, when the environmental information indicates that the temperature at the construction site is 30°C to 40°C, which is close to human body temperature, it becomes difficult for the security sensor to detect an intruder, so the server device 50 may change the detection algorithm using the security sensor so that the intruder is easily detected.
