Summary of the Invention

Problems to be Solved by the Invention

[0004] In the construction of fire alarm facilities, work may be carried out to connect terminal devices such as fire detectors to a fire receiver. During this construction, there may be cases where remote construction management is required or the workers on the construction site change, and in such cases, there may be a need to remotely know the progress of this work. However, as in the technology described in Patent Document 1, simply transmitting event history data to a server via the Internet and making it browsable cannot remotely grasp the progress of the work of connecting terminal devices to a fire receiver.

[0005] An object of the present invention is to enable remotely grasping the progress of the work of connecting terminal devices to a fire receiver.

Means for Solving the Problems

[0006] One aspect of the present invention provides a remote monitoring system comprising: an acquisition unit that acquires data relating to the work of connecting terminal equipment to a fire alarm receiver via the Internet; a calculation unit that calculates an indicator value relating to the progress of the work using the acquired data; and a display unit that displays the calculated indicator value. [Effects of the Invention]

[0007] According to the present invention, the progress of the work of connecting terminal equipment to a fire alarm receiver can be monitored remotely. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0009] (composition) Figure 1 shows an example configuration of a remote monitoring system 1 according to an embodiment. The remote monitoring system 1 comprises a plurality of fire alarm systems 10, a server device 20, and a remote monitoring device 30. The plurality of fire alarm systems 10, the server device 20, and the remote monitoring device 30 are connected via the Internet 40.

[0010] Multiple fire alarm systems 10 are installed in multiple different properties. Each fire alarm system 10 comprises a fire alarm receiver 11 and multiple terminal devices 12. During the installation of the fire alarm system 10, for example, a circuit 13 is connected to the fire alarm receiver 11, and the terminal devices 12 are connected to this circuit 13. Such installation work is performed not only when a new fire alarm system 10 is installed, but also when terminal devices 12 are added to an existing fire alarm system 10. This connects the fire alarm receiver 11 and the terminal devices 12 via the circuit 13. The installation work is an example of the work to connect the terminal devices 12 according to the present invention to the fire alarm receiver 11. The property is an example of a work site according to the present invention.

[0011] The fire alarm receiver 11 manages and controls the terminal equipment 12. When the fire alarm receiver 11 receives a fire signal from the terminal equipment 12, it outputs an alarm. The terminal equipment 12 is equipment connected to the fire alarm receiver 11 via a line 13. When a fire occurs, the terminal equipment 12 performs actions such as fire detection, reporting, fire prevention / smoke prevention, and notification. Examples of terminal equipment 12 include fire detectors, transmitters, fire doors, and sound devices. Note that the terminal equipment 12 is not limited to the equipment exemplified herein and may be other equipment.

[0012] The fire alarm receiver 11 has a recording medium such as a CompactFlash® card. Receiver data 110 is stored on this recording medium. The receiver data 110 includes a receiver database and history data. The receiver database stores various settings used for the operation of the fire alarm receiver 11 and is used to start up the fire alarm receiver 11. The receiver database includes the number of terminal devices 12 that are scheduled to be connected to the fire alarm receiver 11, the number of terminal devices 12 that are actually connected to the fire alarm receiver 11, and the date and time when the terminal devices 12 were connected to the fire alarm receiver 11.

[0013] The number of terminal devices 12 to be connected to the fire alarm receiver 11 is predetermined, for example, by the operation of the construction manager. More specifically, the receiver database assigns a unique address to each terminal device 12, equal to the number of terminal devices 12 to be connected to the fire alarm receiver 11. Therefore, the total number of addresses for the terminal devices 12 equals the number of terminal devices 12 to be connected to the fire alarm receiver 11.

[0014] The number of terminal devices 12 actually connected to the fire alarm receiver 11 can be obtained, for example, by the fire alarm receiver 11 checking the connection status of the terminal devices 12 through polling. For example, the fire alarm receiver 11 periodically sends a status check signal to terminal devices 12 to which addresses have been assigned in the receiver database. If the fire alarm receiver 11 receives a response from a terminal device 12 in response to this status check signal, it recognizes that the terminal device 12 is connected to the fire alarm receiver 11; if there is no response, it recognizes that the terminal device 12 is not connected to the fire alarm receiver 11. Therefore, the total number of terminal devices 12 that responded to the status check signal is the number of terminal devices 12 actually connected to the fire alarm receiver 11. In other words, the number of terminal devices 12 that did not respond to the status check signal is obtained by subtracting the number of terminal devices 12 that did not respond to the status check signal from the number of terminal devices 12 that are scheduled to be connected to the fire alarm receiver 11. For example, if a status check signal is sent to 60 terminal devices 12 that are to be connected to the fire alarm receiver 11, and 50 terminal devices 12 respond, but 10 terminal devices 12 do not, then the actual number of terminal devices 12 connected to the fire alarm receiver 11 will be 50.

[0015] The date and time when terminal device 12 is connected to fire alarm receiver 11 may be entered, for example, by the operation of the construction manager, or it may be the date and time when the connection is confirmed by the connection status confirmation process described above. The connection history of terminal device 12 can be obtained from the date and time when terminal device 12 is connected to fire alarm receiver 11.

[0016] The history data indicates the history of events that occurred in the terminal device 12 or the fire receiver 11. These events include the occurrence of abnormalities, operations, and test results. That is, the history data includes data indicating the operation history of the fire receiver 11.

[0017] In addition, the fire receiver 11 has a gateway function for relaying communication between the line 13 and the Internet 40. More specifically, the fire receiver 11 has a gateway unit that communicates with the server device 20 via the Internet 40. The fire receiver 11 transmits receiver data 110 and the like to the server device 20 at a predetermined time interval by the gateway unit. The predetermined time interval is, for example, one hour. However, the predetermined time interval is not limited to one hour and may be a time interval such as several hours, one day, or several days.

[0018] More specifically, the fire receiver 11 reads the receiver data 110 from the recording medium at a predetermined time interval. Also, the fire receiver 11 generates input data based on this receiver data 110. The receiver data 110 includes data that is not necessary for generating the output data displayed on the remote monitoring device 30. The input data is obtained by extracting data used for generating the output data displayed on the remote monitoring device 30 from the receiver data 110. The input data includes the number of terminal devices 12 planned to be connected to the fire receiver 11, the number of terminal devices 12 actually connected to the fire receiver 11, the date and time when the terminal device 12 was connected to the fire receiver 11, and data indicating the operation history of the fire receiver 11. The fire receiver 11 converts the data format of the input data into a CSV format or a text format that can be read by the server device 20 and the remote monitoring device 30. Then, the fire receiver 11 transmits the receiver data 110 and the input data to the server device 20.

[0019] The server device 20 centrally manages the receiver data 110 and input data received from the fire receivers 11 of each property and provides them to the remote monitoring device 30. In one example, the server device 20 is a cloud server. In another example, the server device 20 may be an on-premises common server. The server device 20 stores the receiver data 110 and input data received from each fire receiver 11 in the central database 201 stored in the storage unit.

[0020] FIG. 2 is a diagram illustrating the central database 201. In the central database 201, the property ID of the property and the data related to that property are stored in association with each other. The data related to the property includes property information, receiver data 110, input data, and output data. The property ID is information that uniquely identifies the property. The property information is information related to the property and the construction of the property. The property information includes, for example, the property name, the delivery date and the name of the worker for the construction in the property, and the address of the property. The property information is input, for example, by the operation of the construction manager. The receiver data 110 and the input data are received from the fire receiver 11. For example, the receiver data 110 and the input data received from the fire receiver 11 of property A are associated with the property ID of property A. The output data is the data displayed on the remote monitoring device 30. The output data is generated by the remote monitoring device 30 based on the input data. As described above, the fire receiver 11 of each property transmits the receiver data 110 and the input data to the server device 20 at a predetermined time interval. When the server device 20 receives the receiver data 110 and the input data from the fire receiver 11 of each property, it updates the central database 201 based on the received receiver data 110 and input data.

[0021] Figure 3 shows an example configuration of the remote monitoring device 30. The remote monitoring device 30 is installed outside the property and is used by the construction manager to remotely monitor the status of fire alarm systems 10 at multiple properties. This manager remotely manages construction work at multiple properties. The remote monitoring device 30 can view the receiver data 110 of each property's fire alarm receiver 11 stored in the server device 20, but it cannot rewrite this receiver data 110. This is to prevent the construction manager from causing disruptions to on-site operations due to erroneous operation. The remote monitoring device 30 is, for example, a personal computer, a tablet terminal, or a mobile terminal. The remote monitoring device 30 comprises a control unit 31, a storage unit 32, a communication unit 33, an operation unit 34, and a display unit 35. The control unit 31 is connected to the storage unit 32, the communication unit 33, the operation unit 34, and the display unit 35 via a bus.

[0022] The control unit 31 controls various parts of the remote monitoring device 30 and performs various processes. The control unit 31 includes a processor such as a CPU. The storage unit 32 stores programs for realizing the functions of the remote monitoring device 30 and various data. The storage unit 32 includes memory such as ROM and RAM, and storage such as an HDD and SSD. The communication unit 33 communicates with the server device 20 via the internet 40. The communication unit 33 includes a network adapter, for example. The operation unit 34 is used to operate the remote monitoring device 30. The operation unit 34 includes a keyboard and mouse, for example. The display unit 35 displays various information. The display unit 35 includes a liquid crystal display, for example.

[0023] The control unit 31 functions as an acquisition unit 311, a calculation unit 312, a transmission unit 313, and a display control unit 314. These functions are realized by the control unit 31 executing a program stored in the storage unit 32 to perform calculations or control each part of the remote monitoring device 30. At least some of the functions of the control unit 31 may be realized by hardware modules such as electronic circuits.

[0024] The acquisition unit 311 acquires property information and input data for each property from the server device 20. Property information includes, for example, the property name, delivery date, worker, and address. Input data includes, for example, the number of terminal devices 12 that are scheduled to be connected to the fire alarm receiver 11, the number of terminal devices 12 that are actually connected to the fire alarm receiver 11, the date and time when the terminal devices 12 were connected to the fire alarm receiver 11, and data indicating the operation history of the fire alarm receiver 11. The input data is an example of data related to the operation of connecting terminal devices 12 to the fire alarm receiver 11 according to the present invention.

[0025] The calculation unit 312 uses the input data acquired by the acquisition unit 311 to calculate indicator values ​​related to the progress of construction work for each project. The indicator values ​​are values ​​used to quantitatively evaluate the progress of construction work. The indicator values ​​are used by construction managers to grasp the progress of construction work and to review deadline management and personnel allocation. The indicator values ​​related to the progress of construction work include the connection rate of terminal equipment 12 to the fire alarm receiver 11, the number of terminal equipment 12 newly connected to the fire alarm receiver 11 per unit time in the target time, the difference between the actual construction progress at the present time and the construction schedule, and the current construction delay rate.

[0026] The connection rate of terminal devices 12 to the fire alarm receiver 11 is the ratio of the number of terminal devices 12 actually connected to the fire alarm receiver 11 to the number of terminal devices 12 that are scheduled to be connected to the fire alarm receiver 11. The number of terminal devices 12 that are scheduled to be connected to the fire alarm receiver 11 and the number of terminal devices 12 that are actually connected to the fire alarm receiver 11 are included in the input data. The calculation unit 312 calculates the connection rate of terminal devices 12 to the fire alarm receiver 11 using the following formula (1). Terminal device connection rate = Number of terminal devices actually connected ÷ Number of terminal devices scheduled to connect × 100 ... (1)

[0027] The number of terminal devices 12 newly connected to the fire alarm receiver 11 per unit time during the target period is the average number of terminal devices 12 newly connected to the fire alarm receiver 11 per unit time during the target period. The target period may be set, for example, by the operation of the construction manager, or it may be set automatically without the operation of the construction manager. The target period may be, for example, several hours to several months. The number of terminal devices 12 newly connected during the target period is obtained by counting the number of terminal devices 12 whose connection to the fire alarm receiver 11 in the input data falls within the target period. The calculation unit 312 calculates the number of terminal devices 12 newly connected to the fire alarm receiver 11 per unit time during the target period using the following formula (2). The number of newly connected terminal devices per unit of time during the target period = Number of newly connected terminal devices during the target period ÷ Target period ... (2)

[0028] Furthermore, by dividing the period from the start of construction to the present into time intervals and sequentially setting these intervals as the target times in the above-mentioned formula (2), a history of the number of terminal devices 12 newly connected to the fire alarm receiver 11 per unit time from the start of construction to the present can be obtained.

[0029] The difference between the current actual construction progress and the construction schedule is the difference between the number of terminal devices 12 currently connected to the fire alarm receiver 11 and the number of terminal devices 12 currently planned to be connected to the fire alarm receiver 11. The number of terminal devices 12 currently connected to the fire alarm receiver 11 is the number of terminal devices 12 currently connected to the fire alarm receiver 11 included in the input data. The number of terminal devices 12 currently planned to be connected to the fire alarm receiver 11 is obtained, for example, by calculating the number of terminal devices 12 currently planned to be connected to the fire alarm receiver 11 per unit time based on the final number of terminal devices 12 planned to be connected to the fire alarm receiver 11 and the deadline, and then multiplying the number of terminal devices 12 currently planned to be connected to the fire alarm receiver 11 per unit time by the time from the start of construction to the present. The final number of terminal devices 12 planned to be connected to the fire alarm receiver 11 is the number of terminal devices 12 currently planned to be connected to the fire alarm receiver 11 included in the input data. The deadline is included in the property information. The calculation unit 312 calculates the difference between the current actual construction progress and the construction schedule using the following formula (3). The difference between the actual construction progress at this point and the planned construction progress = the number of terminal devices currently connected - the number of terminal devices that are planned to be connected at this point... (3)

[0030] If the difference between the current actual construction progress and the planned construction is a positive value, it indicates that the number of terminal devices 12 currently connected to the fire alarm receiver 11 is greater than the number of terminal devices 12 currently planned to be connected to the fire alarm receiver 11. On the other hand, if the difference between the current actual construction progress and the planned construction is a negative value, it indicates that the number of terminal devices 12 currently connected to the fire alarm receiver 11 is less than the number of terminal devices 12 currently planned to be connected to the fire alarm receiver 11.

[0031] The current construction delay rate is the ratio of the difference between the current actual construction progress and the planned construction progress to the number of terminal devices 12 that are currently scheduled to be connected to the fire alarm receiver 11. The calculation unit 312 calculates the current construction delay rate using the following formula (4). Current construction delay rate = Difference between current construction progress and planned construction progress ÷ Number of terminal devices that are scheduled to be connected at this time × 100 ... (4)

[0032] A positive construction delay rate indicates that there are no delays in the construction. Conversely, a negative construction delay rate indicates that there are delays in the construction. When the construction delay rate is negative, a larger absolute value indicates a greater delay.

[0033] The transmission unit 313 sends the index value calculated by the calculation unit 312 as output data to the server device 20. The output data sent to the server device 20 is stored in the central database 201 in association with the corresponding property ID.

[0034] The display control unit 314 generates a construction management screen 350 based on the property information and input data acquired by the acquisition unit 311 and the index values ​​calculated by the calculation unit 312, and displays it on the display unit 35. The construction management screen 350 visualizes the status of construction at each property. The construction management screen 350 displays the progress and delay status of construction at each property. More specifically, the construction management screen 350 displays the connection rate of terminal equipment 12 at each property to the fire alarm receiver 11, the number of terminal equipment 12 newly connected to the fire alarm receiver 11 per unit time during the target period, the difference between the actual construction progress at the present time and the construction schedule, and the current construction delay rate, either numerically or graphically. In addition, the construction management screen 350 displays index values ​​related to the progress of construction at multiple properties in a single row for easy comparison.

[0035] (operation) Figure 4 is a flowchart showing an example of the operation of the remote monitoring device 30. This operation is initiated, for example, when a construction manager uses the operation unit 34 to display the construction management screen 350.

[0036] In step S11, the acquisition unit 311 acquires property information and input data for all properties stored in the central database 201 from the server device 20. For example, if property information and input data for properties A to F are stored in the central database 201, the acquisition unit 311 receives property information and input data for properties A to F from the server device 20 by sending a request to the server device 20 to acquire property information and input data for all properties. The input data for each property includes the number of terminal devices 12 that are scheduled to be connected to the fire alarm receiver 11, the number of terminal devices 12 that are actually connected to the fire alarm receiver 11, the date and time when the terminal devices 12 were connected to the fire alarm receiver 11, and data indicating the operation history of the fire alarm receiver 11.

[0037] In step S12, the calculation unit 312 uses the input data acquired in step S11 to calculate indicator values ​​related to the progress of construction for each property. The indicator values ​​related to the progress of construction include the connection rate of terminal devices 12 to the fire alarm receiver 11, the number of terminal devices 12 newly connected to the fire alarm receiver 11 per unit time during the target period, the difference between the actual construction progress at the present time and the construction schedule, and the current construction delay rate. For example, the calculation unit 312 calculates the connection rate of terminal devices 12 to the fire alarm receiver 11 for each of properties A to F using the formula (1) described above. The calculation unit 312 calculates the number of terminal devices 12 newly connected to the fire alarm receiver 11 per unit time during the target period for each of properties A to F using the formula (2) described above. The calculation unit 312 calculates the difference between the actual construction progress at the present time and the construction schedule for each of properties A to F using the formula (3) described above. The calculation unit 312 calculates the current construction delay rate for each of properties A to F using the formula (4) described above.

[0038] In step S13, the transmission unit 313 transmits the indicator values ​​regarding the progress of construction for each property, calculated in step S12, to the server device 20 as output data. When the server device 20 receives the output data from the remote monitoring device 30, it stores the received output data in the central database 201, associating it with the corresponding property ID. For example, as shown in Figure 2, the server device 20 stores the output data for property A in the central database 201, associating it with the property ID of property A, and stores the output data for property B in the central database 201, associating it with the property ID of property B.

[0039] In step S14, the display control unit 314 generates a construction management screen 350 based on the property information and input data acquired in step S11 and the indicator value related to the progress of the work calculated in step S12, and displays it on the display unit 35.

[0040] Figure 5 shows an example of the display of the construction management screen 350. On this construction management screen 350, information regarding construction projects A to F is arranged vertically. The information regarding construction projects includes the project name, deadline, worker name, address, information indicating the progress of the construction, information indicating the progress of the construction per unit time, information indicating the delay status of the construction, and information indicating the need for additional workers. The information regarding construction projects A to F can be rearranged according to the order of the information indicating the deadline, worker name, address, or need for additional workers, depending on the operation of the construction manager.

[0041] The property name, delivery date, worker name, and address are included in the property information. Information indicating the progress of the construction includes the connection rate of terminal devices 12 to the fire alarm receiver 11 calculated in step S12, the number of terminal devices 12 that are scheduled to be connected to the fire alarm receiver 11 included in the input data, and the number of terminal devices 12 that are actually connected to the fire alarm receiver 11.

[0042] For example, in property A, if there are 7 terminal devices 12 that are scheduled to be connected to the fire alarm receiver 11, and 0 terminal devices 12 are actually connected to the fire alarm receiver 11, the connection rate of terminal devices 12 to the fire alarm receiver 11 will be 0%. In this case, the information showing the progress of the construction in property A will include "Connection 0%" to indicate that the connection rate is 0%, a bar graph showing the connection rate as "0%", and "0 / 7" to indicate that there are 7 terminal devices 12 that are scheduled to be connected to the fire alarm receiver 11, and 0 terminal devices 12 are actually connected to the fire alarm receiver 11.

[0043] The information showing the progress of the work per unit time includes a bar graph showing the history of the number of terminal devices 12 newly connected to the fire alarm receiver 11 per unit time, which is obtained from the number of terminal devices 12 newly connected to the fire alarm receiver 11 per unit time during the target time calculated in step S12. The horizontal axis of this bar graph represents time, and the vertical axis represents the cumulative number of connected terminal devices 12. In addition, the two dashed lines provided horizontally along the vertical axis represent the total number of terminal devices 12 to be connected (upper dashed line) and the number of terminal devices 12 to be connected at the present time (lower dashed line). For example, if 15 new terminal devices 12 are connected to the fire alarm receiver 11 in the 3 hours from 13:00 to 16:00 on a certain day in property B, and the unit time is 1 hour, then the number of terminal devices 12 newly connected to the fire alarm receiver 11 per unit time during these 3 hours is 5. In this case, the information showing the progress of the work in property B includes a bar graph showing that the cumulative number of terminal devices 12 increases by 5 per hour from 13:00 to 16:00 on a certain day.

[0044] Information indicating the construction delay status includes the difference between the actual construction progress at the present time and the planned construction time, calculated in step S12, and the current construction delay rate. For example, if the number of terminal devices 12 actually connected to the fire alarm receiver 11 at the present time in property B is 285, and the number of terminal devices 12 that are scheduled to be connected to the fire alarm receiver 11 at the present time is 300, then the difference between the actual construction progress at the present time and the planned construction time is -15, and the current construction delay rate is -5%. In this case, the information indicating the construction delay status in property A includes the delay rate of "-5%" and the difference of "-15".

[0045] Furthermore, the background color of the construction information for each property may be changed depending on the construction delay rate for that property. For example, if the construction delay rate is between -5% and 20%, the background color may be changed to yellow, and if the construction delay rate is between -20% and 100%, the background color may be changed to red.

[0046] Information indicating the need to increase the number of workers includes "Yes" indicating that an increase in workers is necessary, "No" indicating that an increase in workers is not necessary, and the number of workers needed if an increase is required. The need to increase the number of workers is determined according to the delay rate of the construction work described above. The correspondence between the need to increase the number of workers and the delay rate of the construction work is predetermined. For example, if the delay rate of the construction work is between -5% and -20%, one additional worker is needed, and if the current delay rate of the construction work is between -20% and -100%, two additional workers are needed. This correspondence is predetermined, and a table showing this correspondence is stored in the storage unit 32 in advance. According to this table, if the delay rate of the construction work for property B is -5%, one additional worker is needed, so the information indicating the need to increase the number of workers includes "Yes" indicating that an increase in workers is necessary, and "+1 person" indicating that one additional worker is needed. On the other hand, if the construction delay rate for property C is +13% (progressing ahead of schedule), there is no need to increase the workforce, so the information indicating the need to increase the workforce includes "None," which indicates that no additional workforce is needed.

[0047] The construction management screen 350 displays, in a vertical order, the indicator values ​​related to the progress of construction for projects A to F, namely the connection rate of terminal equipment 12 to the fire alarm receiver 11, the number of terminal equipment 12 newly connected to the fire alarm receiver 11 per unit time during the target period, the difference between the actual construction progress at the present time and the construction schedule, and the current construction delay rate. Therefore, by looking at this construction management screen 350, the construction manager can easily compare the progress and delay status of construction for projects A to F. For example, as shown in Figure 5, if project B requires one additional worker, while project C does not require an additional worker and is not experiencing any construction delays, the construction manager can easily make decisions regarding personnel changes, such as transferring one worker from project C to project B.

[0048] The central database 201 of the server device 20 is updated each time receiver data 110 and input data are transmitted from the fire alarm receiver 11 of each property at predetermined time intervals. When the central database 201 is updated, the processes in steps S11 to S14 described above are performed, and the construction management screen 350 is also updated. This update of the construction management screen 350 may be performed in response to an operation by the construction manager, or it may be performed automatically without an operation by the construction manager.

[0049] Figure 6 shows an example of updating the construction management screen 350. In Figure 6, only the information showing the progress of the construction of property A, which is included in the construction management screen 350 shown in Figure 5, is displayed, and the illustration of other information is omitted. Here, we will explain using the example of a case in property A where a total of 7 terminal devices 12, consisting of 5 fire detectors and 2 fire doors, are connected in the new construction of the fire alarm system 10. The number of terminal devices 12 that are scheduled to be connected to the fire receiver 11 in the new construction is 7. At the start of construction, the number of terminal devices 12 actually connected to the fire receiver 11 is 0, so the connection rate of terminal devices 12 to the fire receiver 11 is 0%. In this case, the information showing the progress of the construction of property A includes "Connection 0%" to indicate that the connection rate is 0%, a bar graph showing the connection rate of "0%", and "0 / 7" to indicate that the number of terminal devices 12 that are scheduled to be connected to the fire receiver 11 is 7, and the number of terminal devices 12 actually connected to the fire receiver 11 is 0.

[0050] Next, when five fire detectors are connected to the fire receiver 11, the number of terminal devices 12 actually connected to the fire receiver 11 becomes five, resulting in a connection rate of 71% for terminal devices 12 to the fire receiver 11. In this case, the information showing the progress of the construction of property A includes "Connection 71%" indicating a connection rate of 71%, a bar graph showing the connection rate of "71%", and "5 / 7" indicating that there are seven terminal devices 12 planned to be connected to the fire receiver 11, and five terminal devices 12 are actually connected to the fire receiver 11. Next, when two fire doors are connected to the fire receiver 11, the number of terminal devices 12 actually connected to the fire receiver 11 becomes seven, resulting in a connection rate of 100% for terminal devices 12 to the fire receiver 11. In this case, the information showing the progress of the construction of property A includes "100% connection," indicating that the connection rate is 100%, a bar graph showing the connection rate of "100%", and "7 / 7," indicating that there are 7 terminal devices 12 that are scheduled to be connected to the fire alarm receiver 11, and that there are 7 terminal devices 12 that are actually connected to the fire alarm receiver 11. With this, the new construction is completed.

[0051] Next, let's consider a scenario where, after the completion of the new construction, an additional fire detector is added due to a change in the layout of property A. In this case, the receiver data 110 of the fire alarm receiver 11 of property A is rewritten, and the number of terminal devices 12 to be connected to the fire alarm receiver 11 changes from 7 to 8. As a result of this change, the number of terminal devices 12 to be connected to the fire alarm receiver 11 becomes 8, and the number of terminal devices 12 actually connected to the fire alarm receiver 11 becomes 7, so the connection rate of terminal devices 12 to the fire alarm receiver 11 becomes 88%. When one fire detector is connected to the fire alarm receiver 11 during the additional construction, the number of terminal devices 12 actually connected to the fire alarm receiver 11 becomes 8, so the connection rate of terminal devices 12 to the fire alarm receiver 11 becomes 100% again. In this case, the information showing the progress of the construction on property A includes "100% connection," indicating a 100% connection rate, a bar graph showing the 100% connection rate, and "8 / 8," indicating that there are 8 terminal devices 12 planned to be connected to the fire alarm receiver 11, and 8 terminal devices 12 are actually connected to the fire alarm receiver 11. This completes the expansion work.

[0052] Information showing the progress of construction for projects other than Project A, included in the construction management screen 350, is updated in accordance with updates to the central database 201, just like the information showing the progress of construction for Project A. In addition, information showing the progress of construction per unit time for each project, information showing the status of construction delays, and information showing the need to increase the number of workers, included in the construction management screen 350, are also updated in accordance with updates to the central database 201, just like the information showing the progress of construction.

[0053] According to the embodiment described above, the construction management screen 350 displayed on the remote monitoring device 30 includes indicator values ​​related to the progress of the construction. Therefore, the progress and delay status of the construction connecting the terminal equipment 12 to the fire alarm receiver 11 can be grasped remotely without having to go to the installation site of the fire alarm receiver 11. This allows the construction manager to grasp the progress of the construction and give appropriate instructions to the workers, even when, for example, the workers change midway through the construction due to construction delays or personnel reductions, and it is not possible to hand over or communicate between the workers. Furthermore, since the construction management screen 350 is updated in accordance with updates to the central database 201, the progress and delay status of the construction can be monitored remotely in near real-time.

[0054] Furthermore, the construction management screen 350 displays indicator values ​​related to the progress of construction for multiple projects side by side, making it easy to compare the progress and delay status of construction across multiple projects. In addition, since the progress management of construction for multiple projects is centralized, appropriate personnel allocation can be made according to the progress and delay status of construction, such as by transferring workers between projects. This helps prevent delays in the construction period due to personnel shortages.

[0055] (modified version) The present invention is not limited to the embodiments described above. The embodiments described above are examples and may be implemented in the following modified forms, or in combination of two or more of the following modified forms.

[0056] In the embodiment described above, in the example shown in Figure 5, the construction management screen 350 contains information on construction projects A to F, but it may also contain information on construction projects for only one selected project from these projects. In this case, information on construction projects for other projects will be hidden. According to this modification, when a construction manager manages only the construction of one of several projects, it is possible to prevent this manager from viewing information on construction projects for other projects.

[0057] In the embodiment described above, the remote monitoring device 30 may acquire and display receiver data 110 contained in the central database 201. This allows the construction manager to view the latest receiver data 110 without having to go to the installation site of the fire alarm receiver 11. Furthermore, since the receiver data 110 includes historical data, if there is a malfunction in the fire alarm receiver 11, for example, the construction manager can analyze the historical data remotely without having to go to the installation site of the fire alarm receiver 11 and investigate the cause of the malfunction.
