Description

The present invention relates to a fire alarm system that monitors fires by connecting terminals such as fire detectors and smoke control devices that have unique addresses set to a signal line drawn from a receiver.

Conventionally, in fire alarm systems known as R-type, terminals such as fire detectors with transmission capabilities and unique addresses are connected to signal lines drawn from the receiver, and when a fire is detected, a search command is issued from the receiver based on a fire interrupt from the fire detector to identify the address of the fire detector that triggered the alarm and collect fire data such as smoke density and temperature. If the fire data exceeds a specified fire threshold, it is determined to be a fire, a fire representative light is turned on, a main sound alarm is output, and a fire alarm screen is displayed on the display of the receiver, showing a fire outbreak message, the location of the fire, the time of the fire outbreak, receiver operation guidance, etc.

When installing this type of fire alarm system, work is carried out to connect terminals such as fire detectors and smoke control devices with unique addresses to signal lines drawn from receivers installed in disaster prevention centers, etc., and tests are then conducted on the connected terminals to confirm their operation, with work proceeding in preparation for the final fire inspection.

When installing fire alarm equipment, the receiver is switched to installation and maintenance mode. In installation and maintenance mode, the receiver manages installation terminal information, which indicates whether terminals are connected or not to the signal line, and the results of tests performed on connected terminals. The receiver's display device displays a installation status management screen based on the installation terminal information. The installation status management screen can be viewed by people involved in the construction, such as on-site personnel, subcontractors, and managers, and is used as an important source of information for confirming the construction policy for the fire inspection that is performed after the construction is completed.

However, with this type of fire alarm system, when construction is well underway and nearing completion at a construction site, many people involved in the construction frequently use the receiver to check the terminal information on the receiver screen, which is an information source showing the current status of the construction. This causes congestion in front of the receiver as people wait in line to view the construction status management screen.

For example, on-site personnel can view the construction status management screen to grasp the overall progress of the site and formulate construction policies. Subcontractors can also view the construction status management screen to grasp the status of the work area they are responsible for and to check the status of fire detectors after construction has been completed. Furthermore, construction managers can view the construction status management screen to confirm the on-site schedule and the amount of remaining work, and to ascertain the overall progress of the site.

In addition, construction staff and subcontractors must travel to receivers located far from the construction site to check the construction status management screen, which takes time to travel back and forth.

As such, when installing fire alarm systems, checking the installation status management screen of the receiver, which is the key to on-site management, is a time-consuming and labor-intensive task, placing a heavy burden on those involved in the construction.

The present invention aims to provide a fire alarm system that allows users to simply and easily check the construction status, which indicates the status of the terminal connected to the signal line from the receiver during construction work, without the need to wait in line at the receiver or visit the receiver.

(Basic Effects)
In the present invention, in a fire alarm system that monitors fires by connecting a terminal including a fire detector to a signal line drawn from a receiver, the receiver is provided with a construction terminal management unit that generates and manages construction terminal information showing the construction status of the terminal on the signal line and generates and displays a construction status management screen based on the construction terminal information, and a communication unit that transmits the construction terminal information of the construction terminal management unit to the outside, and a mobile terminal that generates and displays a construction status management screen based on the construction terminal information received by communicating with the communication unit of the receiver is provided, so that construction personnel can easily check the construction status of the terminal by looking at the construction status management screen displayed on the mobile terminal carried by the construction personnel based on the construction terminal information of the receiver without going to the installation location of the receiver and checking the construction status management screen of the receiver, and there is no need to wait in line to view the terminal information on the receiver screen or travel back and forth from a distant construction site to view the receiver screen, eliminating the burden on construction personnel for viewing the construction status of the terminal and making it possible to smoothly and efficiently proceed with construction work for fire inspection.

(Effect of displaying the construction status management screen)
In addition, the construction status management screen and the screen for construction status management are designed to display information indicating terminal not connected, terminal connected, and terminal type corresponding to all or some of the addresses of terminals that can be connected to the signal line, so that the construction status of terminals, including fire detectors, can be easily and reliably checked on the receiver as well as the user's mobile terminal.

(Effect of color-coded display of device status)
In addition, the construction status management screen and the screen for construction status management display all or some of the addresses of terminals that can be connected to signal lines, and displays addresses corresponding to terminals that are not connected and terminals that are not connected in different colors or in different display formats. For example, on the construction status management screen, addresses of terminals that are not connected are displayed in blue, and addresses of terminals that are connected are displayed in red. When looking at the construction status management screen, construction information such as the progress status of terminals such as fire detectors can be confirmed at a glance from the layout of addresses of terminals that are connected and displayed in red.

(Effect of color-coding different types of terminal connections)
In addition, the construction terminal management unit of the receiver stores a construction plan indicating which type of terminal should be connected or not connected to each address of all or some of the addresses of terminals that can be connected to the signal line, and the construction status management screen and the construction status management screen are configured to display the corresponding addresses of the terminal connection in a color-coded manner, so that if a terminal connection different from the construction plan is detected, a predetermined color is displayed to indicate the difference in connection status.For example, in addition to displaying addresses with unconnected terminals in blue and addresses with connected terminals in red, if a terminal of a type different from the construction plan is mistakenly connected among addresses that have been connected to a terminal, the address is displayed in yellow, for example.This allows the construction status management screen to easily check for an incorrect type of terminal connection, and the task of switching to the correct type of terminal connection can be performed efficiently.

(Effect of updating device information on mobile devices)
In addition, the mobile terminal stores the construction terminal information received from the receiver and obtains from the receiver the construction terminal information of an address that has changed since the construction terminal information was stored and updates it. Therefore, it is only necessary to send the construction terminal information that has changed from the receiver to the mobile terminal, and communication efficiency can be improved by reducing the amount of communication.

(Effect of displaying terminal information in the same format as the receiver)
In addition, the mobile terminal displays the construction terminal information received from the receiver on a construction status management screen of the same format as the construction status management screen displayed on the receiver, so that the terminal information can be checked efficiently in the same way as if the user went to the receiver and had the construction terminal information displayed on the receiver screen.

(Effect of displaying mobile terminal state information in a format different from that of the receiver)
In addition, the mobile terminal displays the construction terminal information received from the receiver on a construction status management screen that has been processed in a specific format different from the construction status management screen displayed on the receiver.By displaying the construction terminal information in a format different from the receiver screen as necessary, construction terminal information can be displayed in a format that meets the needs of construction personnel who use the mobile terminal to check the construction status, making it easier to check the construction status.

(Effect of displaying terminal information by dividing into periods)
In addition, the mobile terminal displays the construction terminal information received from the receiver on a construction status management screen, divided into specified time periods. This enables construction personnel to, when the construction progress is behind schedule, determine the cause of the delay by displaying a construction status management sub-screen that specifies a specified past period, and work to resolve the delay.

(Effect of displaying the period-based device information display update section)
In addition, on the mobile terminal, when displaying the screen for managing construction status, the display format of items of construction terminal information that have changed within a specified period is different from the display format of items of construction terminal information that have not changed within a specified period, so that it is possible to simply and easily check whether construction is progressing within a specified period.

(Display of terminal information by system division on mobile terminal)
In addition, the mobile terminal displays the construction terminal information received from the receiver on a construction status management screen, separated by system corresponding to the signal line extracted from the receiver. Therefore, by displaying the construction status management screen on the mobile terminal on a daily basis, construction personnel can accurately grasp the progress of the construction and use this information to determine future construction policies and completion prospects.

(Effect of displaying terminal information by dividing the personnel in charge on a mobile device)
In addition, the mobile terminal displays the construction terminal information received from the receiver on a construction status management screen, separated by each person in charge. This allows construction personnel to grasp the current situation relative to the construction schedule and accurately grasp the progress of the construction work they are in charge of by displaying the construction terminal information, such as the construction area, for which they are in charge, on the construction status management screen of the mobile terminal, enabling them to use this information to determine future construction policies and prospects for completion.

(Effect of direct communication between receiver and mobile device)
The communication unit of the receiver sets a communication area in the installation area of the fire alarm equipment, and a mobile terminal located in the communication area obtains terminal information from the terminal management unit of the receiver and displays it on the screen.Therefore, by setting a simple wireless communication environment such as a wireless LAN in the installation area using the communication unit of the receiver, the terminal information can be obtained from the receiver and used on the user's mobile terminal.

(Communication between receiver and mobile device via server)
The mobile terminal obtains terminal information from the receiver's terminal management unit via a server connected via an external network and displays it on the screen.The receiver's communication unit can then use wide-area wireless environments such as mobile phone networks and Wi-Fi to send terminal information to a server on the Internet, and the terminal information from the server can be received and checked on the mobile terminal carried by the user.This means that the terminal information can be obtained and used even in places other than the construction site, without being restricted by location.

(Effect of the distributed system construction status management screen)
In addition, one or more relay panels are connected to the receiver via a network line, a terminal including a fire detector and an interlocking device is connected to a signal line drawn from the relay panel, construction terminal information showing the construction status of the terminal for the signal line is stored in the relay panel, and when a fire is detected in the relay panel, a distributed system is configured in which the receiver is notified and a fire alarm is output, and the construction terminal management unit generates and displays a construction status management screen of the relay panel based on the construction terminal information stored in the relay panel, and transmits the construction terminal information of the relay panel to a mobile terminal by a communication unit, and the mobile terminal communicates with the communication unit of the receiver and performs construction status management based on the construction terminal information of the relay panel received from the construction terminal management unit. Since a screen for managing the construction status is generated and displayed, construction personnel such as on-site personnel, subcontractors, and construction managers can easily check the construction status of the terminal at the relay panel by looking at the construction status management screen displayed on the mobile terminal carried by the construction personnel based on the construction terminal information of the relay panel, without having to go to the location where the receiver is installed and check the terminal information on the construction status management screen of the relay panel. This eliminates the need to wait in line to view the terminal information on the receiver screen or to travel back and forth from a distant construction site to view the receiver screen, eliminating the burden on construction personnel for viewing the construction status on the relay panel and making it possible to smoothly and efficiently proceed with construction work leading up to fire inspections.

(Effect of sending screen information from the construction status management screen)
In another embodiment of the present invention, in a fire alarm system that monitors fires by connecting a terminal including a fire detector to a signal line drawn from a receiver, the receiver is provided with a construction terminal management unit that generates and manages predetermined construction terminal information indicating the construction status of the terminal on the signal line and generates and displays a construction status management screen based on the construction terminal information, and a communication unit that transmits screen information of the construction status management screen displayed by the construction terminal management unit to the outside. A mobile terminal is provided that displays a copy screen of the construction status management screen based on the screen information received by communicating with the communication unit of the receiver. Therefore, by transmitting the construction status management screen displayed on the receiver to the mobile terminal as a copy screen and displaying it, processing on the mobile terminal side can be simplified compared to sending the construction terminal information generated and managed by the receiver to the mobile terminal to generate and display the construction status management screen. For example, the construction status management screen can be easily checked on a mobile terminal such as a smartphone or tablet terminal.

[Fire alarm system]
(Outline of fire alarm system)
Fig. 1 is an explanatory diagram showing an embodiment of a fire alarm system in which construction management information is displayed on a screen by a receiver. As shown in Fig. 1, in a fire alarm system in which construction work has been completed and the system is in operation, for example, an R-type receiver 10 is installed in a manager's room on the first floor of the building in which the fire alarm system is installed, and signal lines 12-1 to 12-3 are drawn from the receiver 10 to the alert area in separate systems.

Multiple analog fire detectors 14 with transmission capabilities and unique addresses are connected to the signal line 12-1, and an on-off fire detector 18 and a transmitter 20 are connected to a detector line 17 drawn from a repeater 16 with transmission capabilities and unique addresses.

In addition to connecting multiple analog fire detectors 14, an addressable transmitter 22 with a transmission function and a unique address is connected to the signal line 12-2. Furthermore, a smoke control device 24 is connected to the signal line 12-3 via a repeater 16 with a transmission function and a unique address.

Here, the maximum number of addresses set for terminal devices such as analog fire detectors 14 and repeaters 16 connected to signal lines 12-1 to 12-3 is, for example, 255, and terminal devices including a maximum of 255 analog fire detectors 14 can be connected to signal line 12. Note that in the following explanation, when there is no need to distinguish between signal lines 12-1 to 12-3, they may be referred to as signal line 12.

(Receiver functional configuration)
The receiver 10 is provided with a main CPU 26 and a plurality of sub-CPU boards 28-1 to 28-3, and the sub-CPU boards 28-1 to 28-3 are provided with sub-CPUs 30-1 to 30-3 and transmission sections 32-1 to 32-3.

The main CPU 26 and the sub-CPUs 30-1 to 30-3 are connected by a serial transfer bus 34 and transmit and receive data between them. In the following explanation, when there is no need to distinguish between the sub-CPUs 30-1 to 30-3 and the transmission units 32-1 to 32-3, they may be referred to as the sub-CPU 30 and the transmission unit 32.

Connected to the main CPU 26 are a display 36 with a touch panel using a liquid crystal display panel or the like, a display unit 38 equipped with representative lights for fire, gas leaks, and faults, LED indicator lights, etc., an operation unit 40 equipped with a switch for switching between construction and maintenance mode and fire monitoring mode and various switches required for fire monitoring, an audio alarm unit 42 equipped with a speaker, and a reporting unit 44.

The main CPU 26 is also provided with a USB port (not shown), which allows data to be read and written by inserting a portable USB memory.

The main CPU 26 is provided with a fire monitoring control unit 48 and a construction terminal management unit 50 as functions realized by executing a program. The construction terminal management unit 50 functions when the receiver 10 is switched to construction and maintenance mode in conjunction with construction work for the fire alarm system. The fire monitoring control unit 48 also functions during operation when the receiver 10 is switched to fire monitoring mode after construction work for the fire alarm system is completed.

The main CPU 26 also stores construction terminal information 52 related to terminals such as the analog fire detector 14 used for construction terminal management, the repeater 16 to which the on-off fire detector 18 is connected, the addressable transmitter 22, and the repeater 16 to which the smoke control device 24 is connected.

The construction terminal information 52 stored in the main CPU 26 is created by the manufacturer, such as a factory, during the construction stage of the fire alarm system, stored in a USB memory and set in the USB port of the receiver 10, and when the receiver 10 is switched to construction and maintenance mode by a specified operation, the information is read from the USB memory and stored as construction terminal information 52 in the non-volatile memory of the main CPU 26.

Figure 2 is an explanatory diagram showing an example of construction terminal information stored in the receiver. As shown in Figure 2, construction terminal information 52 is divided by system, address, type, line, building, floor, and area, and area names such as "1st floor lobby" and "1st floor 1st conference room east" are stored as display messages that are arbitrary numbers, followed by link destinations such as "1-111", "1-112", and "1-113", which are combinations of system and address, as link destination device information. Construction terminal information 52 also stores construction-related information indicating terminal unconnected, terminal connected, terminal test results, etc., associated with the construction work being carried out.

The construction terminal information 52 stored in the main CPU 26 is used as is as terminal information for displaying the fire area and for linkage control when the construction work for the fire alarm system is completed, the receiver 10 is switched to fire monitoring mode, and the fire monitoring control unit 48 is functioning.

(Fire monitoring and control of receiver)
After the installation of the fire alarm system is completed and the receiver 10 is switched to the fire monitoring mode, the fire monitoring control during operation is as follows.

Taking the example of sub-CPU 30-1 on sub-CPU board 28-1, sub-CPU 30-1 performs fire monitoring control by instructing transmission unit 32-1 to send and receive signals with analog fire detector 14 according to a specified communication protocol.

During normal monitoring, the fire monitoring control by the sub-CPU 30-1 periodically instructs the transmission unit 32-1 to transmit a broadcast batch AD conversion signal including a batch AD conversion command, and the analog fire detector 14 that receives this batch AD conversion signal detects and retains the smoke concentration or temperature as sensor data. Next, the sub-CPU 30-1 transmits a call signal including a polling command that sequentially specifies the terminal addresses.

When the analog fire detector 14 receives a call signal with an address that matches its own address, it transmits a response signal including the analog data of the sensor it is holding at that time to the transmission unit 32-1. In addition, when the analog fire detector 14 detects that the analog data of the sensor has reached a predetermined fire pre-level that is lower than the predetermined fire judgment level, it transmits a fire interrupt signal to the transmission unit 32-1.

When the sub-CPU 30-1 receives a fire interrupt signal via the transmission unit 32-1, it sends a group search command signal to identify the group that includes the analog fire detector 14 that is detecting the fire, then identifies the address of the analog fire detector 14 that is detecting the fire, centrally collects the analog data of the sensor, and transmits it to the main CPU 26 via the serial transfer bus 34.

The main CPU 26 compares the analog data received from the sub-CPU 30-1 with a predetermined fire determination level, and when the analog data reaches the fire determination level, it determines that there is a fire, turns on the fire representative light on the display unit 38, outputs a predetermined main sound alarm indicating a fire from the speaker of the sound alarm unit 42, displays fire alarm information including the location of the fire based on the address of the sensor where the fire was detected on the display 36, and further outputs a fire alarm signal to the outside via the alarm transmission unit 44 to perform predetermined alarm transmission control, etc.

The fire monitoring control by the sub-CPU 30-2 and transmission unit 32-2 provided on the sub-CPU board 28-2 is the same as that of the sub-CPU board 28-1 described above. In addition, the sub-CPU 30-3 and transmission unit 32-3 provided on the sub-CPU board 28-3 perform interlocking control of the smoke control equipment 24 based on the interlocking destination of the construction terminal information 52 shown in Figure 2 when a fire is detected by the main CPU 26.

[Fire alarm system installation]
(Configuration of fire alarm system at the time of installation)
The construction work for the fire alarm system shown in FIG. 1 involves first installing the receiver 10 in a caretaker's room or the like, and then wiring work for pulling and laying the signal lines 12-1 to 12-3 from the receiver 10 toward the security zone.

Next, construction work is performed to connect terminals such as the analog fire detector 14, the repeater 16 connected to the on-off fire detector 18, the addressable transmitter 22, and the repeater 16 connected to the smoke control device 24 to the signal lines 12-1 to 12-3 drawn from the receiver 10. After the connections are connected, tests are performed to confirm that they are working properly, and when all construction work is completed, a fire inspection is performed. If this is passed, the receiver 10 is switched to fire monitoring mode to start operation and enter fire monitoring control. Note that construction work and tests may be performed by switching to fire monitoring mode during construction.

The construction terminal management unit 50, which functions in the construction maintenance mode, generates and manages construction terminal information 52 indicating the construction status of terminals such as analog fire detectors 14, repeaters 16 connected to on-off fire detectors 18, addressable transmitters 22, and smoke control devices 24 for the signal lines 12-1 to 12-3, and also generates a construction status management screen based on the construction terminal information 52 and controls its display on the display 36.

The main CPU 26 is also provided with a wireless LAN communication unit 46 that functions as a communication unit that transmits the construction terminal information 52 generated and managed by the construction terminal management unit 50 to the outside. The wireless LAN communication unit 46 can use a small interface conversion device known as a Wi-Fi (registered trademark) dongle that is inserted into the USB port of the main CPU 26.

The wireless LAN communication unit 46 functions as an interface conversion adapter, and converts between signals conforming to the USB communication protocol and signals conforming to the wireless LAN communication protocol. For example, the wireless LAN communication unit 46 converts between signals conforming to the USB 2.0 or USB 3.0 standard and signals by wireless LAN communication conforming to IEEE 802.11 based on an Ethernet (registered trademark) wireless network, and forms a wireless LAN communication area in the installation area of the fire alarm system.

A portable terminal 54 is provided in correspondence with the wireless LAN communication unit 46 of the receiver 10 and carried by the construction personnel who are carrying out the construction work of the fire alarm system. The portable terminal 54 is connected to the wireless LAN communication unit 46 of the receiver 10 for communication, and generates and displays a construction status management sub-screen based on the construction terminal information 52 received from the construction terminal management unit 50.

(Mobile device)
3 is an explanatory diagram showing an embodiment of a mobile terminal that receives construction management information from a receiver and displays it on a screen. The mobile terminal 54 is composed of a terminal CPU 62, a communication unit 64 connected to an antenna 66, a display 68 with a touch panel using a liquid crystal display panel or the like, and an operation display unit 70.

The terminal CPU 62 is provided with the functions of a terminal control unit 72 that are realized by executing a program. In addition, the memory of the terminal CPU 62 stores construction terminal information 74 received from the receiver 10.

The communication unit 64 transmits and receives signals via wireless LAN communication conforming to IEEE 802.11, which is based on a wireless network using Ethernet (registered trademark), the same as the wireless LAN communication unit 46 of the receiver 10.

The terminal control unit 72 instructs the communication unit 64 via screen operations on the operation display unit 70 or the display 68 to communicate with the wireless LAN communication unit 46 of the receiver 10, receives the construction terminal information 52 generated and managed by the construction terminal management unit 50 of the receiver 10, and stores it in memory as terminal management information 74.

When the terminal control unit 72 first connects to the wireless LAN communication unit 46 of the receiver 10 and receives construction terminal information from the construction terminal management unit 50, it stores the information in memory as is, and then obtains construction terminal information for addresses that have changed from the construction terminal management unit 50 and controls updating of the construction terminal information 74 in the memory. The receiver 10 then transmits the construction terminal information that has changed to the mobile terminal 54, thereby reducing the amount of communication and improving communication efficiency.

In addition, the terminal control unit 72 displays on the display 68 a construction status management sub-screen that is the same as the construction status management screen displayed on the receiver 10 based on the construction terminal information 74 received from the receiver 10 and stored, but it may also display a construction status management sub-screen that has been subjected to a specified processing different from the construction status management screen displayed on the receiver 10.

For example, the terminal control unit 72 can display a construction status management sub-screen that divides the construction terminal information 74 into a predetermined period of time, a construction status management sub-screen that divides the construction terminal information 74 into systems corresponding to the signal lines 12-1 to 12-3 drawn from the receiver 10, or ...

By displaying the construction status management sub-screen processed in this way on the mobile terminal 54, a construction status management sub-screen tailored to the needs of construction personnel who use the mobile terminal 54 to check the construction status is displayed, making it easier to check the construction status.

[Construction status management screen]
Figure 4 is an explanatory diagram showing the construction status management screen before terminal connection work, Figure 5 is an explanatory diagram showing the construction status management screen following Figure 4, Figure 6 is an explanatory diagram showing the construction status management screen following terminal connection work, and Figure 7 is an explanatory diagram showing the construction status management screen following Figure 6.

Note that Figures 4 to 7 show the construction status management screen displayed on the display 36 of the receiver 10, but if the construction status management sub-screen displayed on the display 68 of the mobile terminal 54 has the same display format, it will be the same as the construction status management screen of the receiver 10. Therefore, the following explanation of the construction status management screen of the receiver 10 will also explain the construction status management sub-screen of the mobile terminal 54.

(Initial screen before terminal connection work)
As shown in Fig. 4, a construction status management screen 76-1 (including a construction status management sub-screen for the mobile terminal 54) displayed on the display 36 of the receiver 10 before the start of terminal connection work has a terminal address display section 78, in which a binary address map arranged in rows and columns is displayed if the maximum number of addresses for the signal line 12 shown in Fig. 1 is 255 addresses. Here, Fig. 5 shows a case where the terminal address display section 78 in Fig. 4 is scrolled up to the maximum address of 255.

The binary address map of the terminal address display section 78 shown in Figures 4 and 5 shows column addresses 000 to 250 divided into 10 address units in two columns, and row addresses 0 to 9 divided into 1 address units in the row direction. At the address positions of addresses 001 to 255 determined by the column addresses and row addresses, the symbol "Not yet" is displayed, indicating that a terminal is scheduled to be connected based on the construction terminal information 52 in Figure 2, indicating that the terminal is not yet connected.

For example, in the terminal address display section 78 of FIG. 4, addresses 001, 002, 011-014, 016-018, 021-029, ... are marked with the symbol "not connected" to indicate that the terminal is not connected.

The construction status management screen 76-1 also has operation buttons used to operate the screen, such as a list button 80, a details button 82, an open yesterday button 84, an open today button 86, and a calendar selection button 88. Here, the list button 80 is used to cause the terminal address display section 78 to display the entire address shown in the figure. The details button 82 is used to cause the terminal address display section 78 to display detailed terminal information by narrowing down the address range.

The construction status management screen 76-1 also has a Yesterday Open button 84, Today Open button 86, and Calendar selection button 88, which are used to specify the period of the construction status to be displayed on the terminal address display section 78, and are used to select and display yesterday's construction status, today's construction status, or the construction status for a date selected from the calendar.

In addition, the construction status management screen 76-1 has operation buttons for displaying the terminal status such as sensitivity and faults, but these are not shown in the figure. The operation buttons of the construction status management screen 76-1 are the same as those of the other construction status management screens 76-2.

For example, terminal construction is carried out on the signal line 12 drawn from the receiver 10 in Fig. 1 to connect the analog fire detector 14, the repeater 16 to which the on-off fire detector 18 is connected, the addressable transmitter 22, the smoke control device 24, etc., and when, for example, the today's opening button 86 is operated in conjunction with this terminal construction, construction status management screens 76-3 and 76-4 shown in Fig. 6 and Fig. 7 are displayed on the display 36 of the receiver 10 (including the construction status management sub-screen displayed on the display 68 of the mobile terminal 54). Note that Fig. 7 shows a screen in which the terminal address display section 78 in Fig. 6 is scrolled up to the maximum address of 255.

In the construction status management screen 76-3 in FIG. 6, when terminal connection work for analog fire detectors 14 and the like is performed, the sub-CPU 30 instructs the transmission unit 32 to send a call signal, and the terminal type is detected by receiving a call response signal to the call signal, and then a type call signal is sent based on the terminal connection address, and the terminal type is detected. Therefore, the code "not connected" for the address where the terminal connection and terminal type are detected is displayed as the codes "transmitter", "smoke", "heat", "on", "gas", etc., which indicate the terminal connection and type. Here, "transmitter" indicates the transmitter, "smoke" indicates the smoke detector, "heat" indicates the heat detector, "on" indicates the general-purpose digital input terminal, and "gas" indicates the gas leak alarm.

The construction status management screens 76-3, 76-4 and the like shown in FIG. 6 and FIG. 7, which can be displayed on the display 36 of the receiver 10, are connected to the communication unit 46 of the receiver 10 by the operation of the mobile terminal 54 carried by the construction personnel shown in FIG. 1. By receiving the construction terminal information 52 generated and managed by the construction terminal management unit 50 at that time, the same screen is displayed as a construction status management sub-screen on the display 68 of the mobile terminal 54. The construction personnel can easily check the construction status of the terminal by viewing the construction status management sub-screens same as the construction status management screens 76-1, 76-2 displayed on the mobile terminal 54 as necessary. This eliminates the need to wait in line to view the terminal information on the receiver screen or to travel back and forth from a distant construction cost site to view the receiver screen, thereby eliminating the burden on the construction personnel to view the construction status on the terminal and enabling the construction work for the fire inspection to proceed smoothly and efficiently.

"Construction terminal management control"
FIG. 8 is a flow chart showing the construction management control by the receiver, which is a control operation by the construction terminal management section 50 provided in the receiver 10 in FIG.

As shown in FIG. 8, when the receiver 10 is switched to construction maintenance mode by a specified operation and started up, the construction terminal management unit 50 reads the construction terminal information 52 shown in FIG. 2 from, for example, a USB memory connected to the USB port of the main CPU 26, stores it in memory, and then generates, for example, the construction status management screen 76-1 in FIG. 4, which serves as the initial screen before the start of terminal construction, and displays it on the display 36.

Then, the construction terminal management unit 50, in response to a control instruction to the sub-CPU 30, operates each transmission unit 32 to repeatedly perform terminal call control by transmitting a batch AD conversion signal and a call signal with sequentially specified addresses to the signal line 12.

In response to this terminal call control, when the construction terminal management unit 50 determines in step S4 that the sub-CPU 30 has received a call response signal, it proceeds to step S5, detects the terminal connection of the terminal address that sent the call response signal, and updates the terminal not connected to the terminal connected for the corresponding address in the construction terminal information 52.

Then, the construction terminal management unit 50 instructs the sub-CPU 30 to send a type request signal specifying the address where the terminal connection was detected from the transmission unit 32 to the signal line 12, detects the terminal type of the address where the terminal connection was detected from the response signal, and updates the terminal type of the corresponding address in the construction terminal information 52.

Then, based on the construction terminal information 52 updated to the terminal connection detected in step S5 and the terminal type detected in step S6, the construction terminal management unit 50 generates a construction status management screen 76-3, for example, as shown in FIG. 6, to which a code indicating the newly detected terminal connection and terminal type is added in step S7, and displays the screen on the display 36.

If the terminal type detected by sending the type request signal in step S6 does not match the terminal type in the construction terminal information 52, the construction terminal management unit 50 determines that a type error has occurred and displays a fault message on the construction status management screen indicating that a terminal of an incorrect type has been connected.

Next, when the construction terminal management unit 50 determines in step S8 that the mobile terminal 54 has been connected to the wireless LAN communication unit 46, the process proceeds to step S9, where the construction terminal management unit 50 reads out the construction terminal information 52 from the memory that it has generated and managed, and transmits the information to the mobile terminal 54. The construction terminal management unit 50 then returns to step S3, and repeats the processes from S3 to S9.

[Display control of construction status management screen using mobile terminal]
FIG. 9 is a flow chart showing the display control of the construction status management sub-screen on the mobile terminal, which corresponds to the control operation of the terminal control unit 72 shown in FIG.

As shown in FIG. 9, when a construction worker wants to check the construction status, he or she activates the mobile terminal 54 he or she is carrying, and the terminal control unit 72 connects to the receiver 10 for communication in step S11, and requests the transmission of construction terminal information in step S12, thereby receiving the construction terminal information 52 generated and managed by the construction terminal management unit 50 of the receiver 10 and storing it in memory as construction terminal information 74.

Then, the terminal control unit 72 generates a construction status management sub-screen, for example the same as the construction status management screen 76-3 shown in FIG. 6, based on the construction terminal information 74 stored in memory, displays it on the display 68, and in step S14, disconnects the communication connection with the receiver 10.

Next, if there is a screen operation on, for example, the construction status monitoring sub-screen displayed on the display 68, the terminal control unit 72 generates and displays a construction status management sub-screen corresponding to this screen operation. For example, in response to a button operation on the construction status management sub-screen that is the same as the yesterday open button 84, today open button 86, or calendar selection button 88 on the construction status management screen 76-3, the terminal control unit 72 generates a construction status management sub-screen for the day specified by the button operation and displays it on the display 68.

Then, in step S16, the terminal control unit 72 determines whether or not there is a communication connection timing set at a predetermined cycle, and if so, returns to step S11 and repeats the processing of steps S11 to S16.

If the terminal control unit 72 does not determine the communication connection timing in step S16, it proceeds to step S17, if the stop operation is not determined, it repeats the process from step S15, and if the stop operation is determined, it ends the operation.

[Another embodiment of the construction status management screen]
Figure 10 is an explanatory diagram showing the display format of the construction status management screen using an address map, Figure 11 is an explanatory diagram showing the construction status management screen using the address map before terminal connection work, and Figure 12 is an explanatory diagram showing the construction status management screen using the address map following terminal connection work.

Note that Figures 10 to 12 show the construction status management screen displayed on the display 36 of the receiver 10, but if the construction status management sub-screen displayed on the display 68 of the mobile terminal 54 has the same display format, it will be the same as the construction status management screen of the receiver 10. Therefore, the following explanation of the construction status management screen of the receiver 10 will also explain the construction status management sub-screen of the mobile terminal 54.

(Display format of construction status management screen)
As shown in Fig. 10, the display format of the construction status management screen 100-1 of this embodiment is such that the addresses 001 to 129 of the addresses 001 to 255 per signal line 12 shown in Fig. 1 are displayed as an address map arranged in rows and columns of 10 addresses in the terminal address display section 102. The remaining addresses 130 to 255 can be displayed by scrolling the terminal address display section 102 as shown in Fig. 11.

The construction status management screen 100-1 also has operation buttons used to operate the screen, such as a list button 80, a details button 82, an open yesterday button 84, an open today button 86, and a calendar selection button 88, in the same way as the construction status management screen 76-1 in FIG. 4.

(Initial screen before terminal connection work)
When the receiver 10 in Figure 1 is started up in a state in which it has been switched to construction maintenance mode by a specified operation, the construction status management screen 100-2 shown in Figure 11 is displayed as the initial screen on the display 36 of the receiver 10 based on the construction terminal information 52 stored in memory by the construction terminal management unit 50 (including the construction status management sub-screen displayed on the display 68 of the mobile terminal 54).

The construction status management screen 100-2 displayed as the initial screen shows addresses to which terminals are scheduled to be connected based on the construction terminal information 52 in the terminal address display section 102 as terminal unconnected addresses 110 with a sandy background color of, for example, blue. For example, the terminal unconnected addresses 110 in the terminal address display section 102 are addresses 001, 002, 011-014, 016-018, 021-029, etc., shown with a sandy blue background color.

(Device connection screen)
When terminal construction is carried out to connect an analog fire detector 14, a repeater 16 to which an on-off fire detector 18 is connected, an addressable transmitter 22, a smoke control device 24, etc. to the signal line 12 pulled out from the receiver 10 in Figure 1, for example, a construction status management screen 100-3 shown in Figure 12 is displayed on the display 36 of the receiver 10 or the display 68 of the mobile terminal 54 (including a construction status management sub-screen displayed on the display 68 of the mobile terminal 54).

In the terminal address display section 102 of the construction status management screen 100-3, the terminal connection address 112 is displayed with diagonal lines, for example with a red background color, for the terminal address for which the terminal connection and type have been detected. For example, the addresses 001, 002, 011 to 013, 030 to 036, ... are displayed with diagonal lines and a red background color as the terminal connection addresses 112 in the terminal address display section 102.

In addition, if a type error is detected in which the terminal type detected for the address that has become a terminal connection is different from the terminal type in the construction terminal information 52 in Figure 1, the type error address 114 is displayed, for example, with a yellow background, as shown in addresses 047 to 049 where the type error occurred.

In this way, the terminal address display section 102 displays an address map with color-coded indications of terminal not connected, terminal connected, and type error. This allows the construction status to be intuitively understood, such as terminal not connected, terminal connected, and terminal with type error, not only when the construction status management screen 100-3 is displayed on the display 36 of the receiver 10, but also when a construction worker displays the same construction status management sub-screen on the display 68 of the mobile terminal 54, by looking at the color-coded indication with blue, red, and yellow backgrounds in the terminal address display section 102 of the construction status management screen 100-3.

In addition, by viewing the construction terminal management sub-screen, which is the same as the construction status management screen 100-3 during construction work, on the mobile terminal 54 as needed by construction personnel, the construction status of the terminal can be easily and reliably confirmed, eliminating the need to wait in line to view terminal information on the receiver screen or to travel back and forth to view the receiver screen from a distant construction site. This eliminates the burden on construction personnel to view the construction status of the terminal and enables construction work in preparation for fire inspection to proceed smoothly and efficiently.

(Color-coded screen displayed by staff)
Fig. 13 is an explanatory diagram showing a construction status management screen using an address map in which the persons in charge are color-coded. Note that Fig. 13 shows the construction status management screen displayed on the display 36 of the receiver 10, but if the construction status management sub-screen displayed on the display 68 of the mobile terminal 54 has the same display format, it will be the same as the construction status management screen of the receiver 10. Therefore, the following explanation of the construction status management screen of the receiver 10 will also explain the construction status management sub-screen of the mobile terminal 54.

As shown in FIG. 13, during terminal connection work, if the person in charge button 106 is operated to open a dialogue (not shown) and a specific person in charge is selected from the dialogue, the terminal connection address of the selected person in charge is displayed in the terminal address display section 102 as the construction status management screen 100-4, for example, as the person in charge terminal connection address 116, which is indicated by a sandy diagonal line, for example, with a purple background color set.

By displaying the person in charge's terminal connection address 116 in a color-coded manner according to the person in charge's selection, the construction manager can easily and readily grasp the progress of the construction work by the person in charge of the cooperating company, etc., and use this information to manage the entire construction work.

[Communication connection via server]
FIG. 14 is an explanatory diagram showing an embodiment of a fire alarm system in which construction management information is transmitted from a receiver to a mobile terminal via a server.

As shown in FIG. 14, the fire alarm system of this embodiment is characterized in that the communication connection between the wireless router 47 installed in the receiver 10 and the mobile terminal 54 carried by the construction personnel in the construction area is established via a wide area wireless communication network 56, which serves as an external network, and a server 60 connected to the Internet 58.

The wireless router 47 functions as an interface conversion adapter, converting between signals conforming to the USB 2.0 or USB 3.0 standard, for example, and signals for wireless LAN communication conforming to IEEE 802.11, which is based on an Ethernet (registered trademark) wireless network.

In this wireless LAN communication, the wireless router 47 functions as a wireless LAN station, and establishes a communication connection with a wide area wireless communication network 56 such as WiFi (registered trademark) that functions as an access point to transmit and receive packet signals, and establishes communication connections with a server 60 on the Internet 58 and with mobile terminals 54 carried by construction personnel in the construction area to transmit and receive packet signals. Note that a mobile phone network may be used as the wide area wireless communication network 56.

Other than this, the configuration and functions are the same as those of the embodiment in Figure 1, so the same reference numerals are used and the description is omitted.

In this way, the receiver 10 and the mobile terminal 54 are connected by communication via the server 60, which is connected by communication via the wide area wireless communication network 56 and the Internet 58. The construction terminal information 52 is received from the receiver 10 by way of the server 60, and the construction status management sub-screen is displayed. The display of the construction status management sub-screen on the mobile terminal 54 can be displayed and checked not only at the construction site, but also by construction companies and the like that are far from the construction site. This makes it possible to grasp the construction status of the fire alarm system on a wide area basis, and to efficiently proceed with the construction work.

[Data change in a distributed system consisting of receivers and relay panels]
FIG. 15 is an explanatory diagram showing an embodiment of a fire alarm system in which the construction status of a relay panel is displayed on a screen by a receiver.

When the facility to be monitored is large, for example divided into multiple buildings, a relay panel 120 is installed for each building, for example, with respect to a receiver 10 installed in a disaster prevention center, as shown in FIG. 15, and the receivers 10 and the relay panel 120 are connected for communication by a network line 126 such as Ethernet (registered trademark).

The receiver 10 is the same as that shown in FIG. 1, whereas the relay panel 120 is configured with the exception of the receiver 10 in FIG. 1, excluding the operation and display functions including the display 36, display unit 38, operation unit 40 and audio alarm unit 42. Other than that, it is basically the same as the receiver 10, and terminal devices including the analog fire detector 14 are connected to the transmission line 122 drawn out to the alert area in the same way as the receiver 10, and furthermore, construction terminal information 124 is stored for each relay panel 120.

The receiver 10 is provided with the function of a construction terminal management unit 50, which, like the embodiment of FIG. 1, generates and displays a construction status management screen based on its own construction terminal information 52 and can display a construction status management sub-screen by communicating with a mobile terminal 54. In addition, based on the operation of checking the construction status of the relay panel 120 in the receiver 10, a data transfer request is made to the specified relay panel 120 via a network line 126 to obtain the construction terminal information 124 of the relay panel 120, and based on the construction terminal information 124 generated and managed by the relay panel 120, a construction status management screen for the relay panel 120 is generated and displayed, and further, a construction status management sub-screen for the relay panel 120 can be displayed by communicating with a mobile terminal 54.

Therefore, construction personnel such as on-site personnel, subcontractors, and construction managers can easily check the construction status of the terminal on the relay panel 120 by looking at the construction status management sub-screen displayed on the mobile terminal carried by the construction personnel based on the construction terminal information 124 of the relay panel 120, without having to go to the installation site of the receiver 10 to check the terminal information on the construction status management screen of the relay panel 120. This eliminates the need to wait in line to check the construction status of the relay panel 120 on the receiver screen or to travel back and forth from a distant construction cost site to view the receiver screen, eliminating the burden on construction personnel to check the construction status of the terminal on the relay panel 120 and making it possible to smoothly and efficiently proceed with construction work in preparation for fire inspection.

[Send screen information from the construction status management screen]
In another embodiment of the present invention, a mobile terminal carried by a construction worker may communicate with a communication unit of the receiver to receive screen information of the construction status screen displayed by the construction terminal management unit of the receiver, and display a copy of the construction status management screen received from the construction terminal management unit as a construction status management sub-screen. In this case, the receiver transmits the construction status management screen generated at that time to the mobile terminal at a predetermined period and/or each time there is a change in the terminal information, and stores it therein.

The mobile terminal therefore stores and holds the construction status management screen generated by the receiver as a history screen, and can display a construction status management sub-screen such as yesterday, today, or a selected calendar date by selecting a period as necessary. In addition, by continuously reading and displaying the construction status management screen history screen for a specified period, the construction status management sub-screen can be displayed by playing slides.

In this way, by sending the construction status management screen displayed on the receiver to the mobile terminal as a copy screen and displaying it as a construction status management sub-screen, processing on the mobile terminal side can be simplified compared to sending the construction terminal information generated and managed by the receiver to the mobile terminal to generate and display the construction status management sub-screen. For example, it becomes possible to easily display and check the construction status management sub-screen on a smartphone, tablet terminal, etc.

[Modifications of the present invention]
(P-type receiver)
The above embodiment takes as an example a fire alarm system in which an R-type fire detector is connected via a signal line from an R-type receiver, but in the case of a fire alarm system in which an addressable fire detector with a transmission function is connected and an address is set on the detector line drawn from a P-type receiver, the construction terminal information generated and managed by the construction terminal management section of the receiver can be sent to the mobile terminal of a person involved in the construction to display the construction status management sub-screen.

(Display of the processing screen on a mobile device)
In the above embodiment, an example is given of a case where screen processing similar to that of the receiver's construction status management screen is performed on a mobile terminal, but it is also possible to perform screen processing specific to the mobile terminal so that the construction status management sub-screen is displayed on the mobile terminal.

(others)
On the construction status management screen, the connection status of each address is displayed with symbols such as "Not yet", "Smoke", "Heat", "On", "Gas", etc., but it is also possible to display it using appropriate symbols such as alphabets or specified pictograms.

The present invention also includes appropriate modifications that do not impair its objectives and advantages, and is not limited by the numerical values shown in the above embodiments.
