Description

The present invention relates to a disaster prevention system that monitors for abnormalities such as fires by connecting multiple types of terminal devices, such as fire detectors and smoke control devices, to a signal line drawn from a receiver.

In conventional fire alarm systems known as R-type (Record-type), a terminal such as a fire detector with a transmission function and set to a unique address is connected to a signal line drawn from a 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 concentration 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, and a main sound alarm is output. In addition, a fire alert screen is displayed on a display installed in the receiver, and the fire alert screen shows a fire alert message, the location of the fire, the time of the fire, receiver operation guidance, etc., making it possible to operate the screen to take necessary measures against the fire.

In addition, during construction work or regular inspections, the display can be switched to maintenance mode to display a maintenance screen, which allows the user to select a maintenance menu such as testing, terminal equipment status, fault information, history, and property information. The screen displays a terminal information screen showing, for example, a test screen or the status of the terminal equipment corresponding to the maintenance menu selected, allowing the user to check and operate the test of fire detectors and the linked control of smoke control and evacuation equipment.

However, when using the screen display of such conventional receiver displays to test, for example, fire detectors, an inspector is required to check the operation of the receiver when the fire detector issues a test alarm, in addition to the inspector who tests the fire detector on-site. Also, during construction work, in order to check the progress of the work based on the installation status of the fire detectors, it is necessary to go to the location where the receiver is installed and view the terminal information on the display, which is time-consuming and requires a large workload.

One possible solution to this problem would be to display terminal information on the terminal display and operate the screen using a remote graphical user interface (remote GUI) on a mobile terminal such as a tablet, while displaying the screen currently being displayed on the receiver display using the receiver's graphical user interface (GUI) (Patent Document 3).

However, when a tablet device's remote graphical user interface is connected to the receiver's graphical user interface, operations using the receiver's screen are monopolized by the tablet device, and until the tablet device connection is released, the receiver's screen automatically switches in response to operations on the tablet device, making it impossible to operate the receiver screen.

There is also a method in which screen data is created in advance on the tablet and the content displayed on the screen is changed in response to a signal from the receiver, but this method requires that receiver-specific information, such as the section name, be stored on the tablet. If the tablet belongs to the inspector and is not unique to the receiver, there are still issues that must be considered from the perspective of protecting customer information.

The present invention aims to provide a disaster prevention system that enables remote screen operation and screen display on a mobile terminal while maintaining the screen operation and screen display of the receiver.

Equipped with
The terminal screen display unit can display a receiver display content screen and an external receiver display content screen.

In the following explanation, the receiver display content screen may be referred to as the "current screen" and the external receiver display content screen may be referred to as the "hidden screen."

including.

(Avoiding duplication of operation information from mobile devices)
When operation information from a plurality of mobile terminals overlaps, the receiver permits at least one of the pieces of operation information and inhibits the remaining pieces of operation information.

(Basic Effects)
The present invention comprises a screen generation unit that generates a screen, a receiver screen display unit that is provided in the receiver and displays content based on a portion of the screen, and a terminal screen display unit that is provided in the mobile terminal and displays content including a portion of the screen that is not displayed on the receiver screen display unit.Since the screen is generated in the receiver or server, there is no need to generate the screen on a mobile terminal such as a tablet, and therefore it is possible to display information about the receiver without storing receiver-specific information on the mobile terminal.

(The effect of displaying a screen that reproduces the contents displayed on the receiver and another screen on a mobile device)
The portable terminal also includes a receiver display content screen extraction unit which extracts, based on the screen, content including the portion of the screen that is displayed on the receiver screen display unit as a receiver display content screen (current screen), and a receiver external display content screen extraction unit which extracts, based on the screen, content based on the portion of the screen that is not displayed on the receiver screen display unit as a receiver external display content screen (hidden screen).The terminal screen display unit is capable of displaying the receiver display content screen and the receiver external display content screen, so that the receiver display content screen (current screen) and the receiver external display content screen (hidden screen) can be viewed simultaneously on the portable terminal as necessary.

(Effect of two screens)
In addition, the portable terminal is capable of simultaneously displaying the receiver display content screen and the outside receiver display content screen by the terminal screen display unit, so that the hidden screen can be reliably displayed on the display of the portable terminal without being restricted by the current screen.

(Front and back overlapping screens)
In addition, based on a specified screen switching operation, the mobile terminal displays either the receiver display content screen (current screen) or the receiver external display content screen (hidden screen) as the previous screen via the terminal screen display unit. Therefore, even if the screen size of the mobile terminal is approximately the same as that of the receiver, the receiver display content screen (current screen) and the receiver external display content screen (hidden screen) can be displayed clearly by utilizing the screen size as is.

(Effect of screen display by operating a mobile device)
Furthermore, when the mobile terminal receives an operation on the display content displayed on the mobile terminal, it transmits operation information including at least the position information of the operation on the screen. Therefore, there is no need to link operation commands corresponding to icons, buttons, pull-down menus, etc. arranged on the current screen or hidden screen displayed on the display of the mobile terminal. By simply transmitting coordinate information indicating the screen operation position to the receiver, the operation command on the receiver side is activated and the corresponding processing is performed, thereby simplifying the remote screen operation function arranged on the mobile terminal side.

In addition, even if the current screen or hidden screen is operated on the mobile terminal, the receiver screen operation is not monopolized by the mobile terminal, preventing the receiver screen operation, and remote screen operation and screen display on the mobile terminal can be performed in parallel while maintaining the receiver screen operation and screen display.

(Effect of the receiver's screen generator)
In addition, the receiver is equipped with a screen generation unit, and when operation information from the mobile terminal is received, it executes processing based on the operation information and changes the screen, making it possible to remotely control the receiver, such as switching the screen, by operating the hidden screen displayed on the mobile terminal, which includes parts not displayed on the receiver.

(Example of effect based on receiver display content screen and external receiver display content screen)
In addition, the receiver display content screen (current screen) is a normal monitoring screen on which at least a maintenance menu is arranged, and the receiver external display content screen (hidden screen) includes a test screen including at least a test menu generated by screen operation of the maintenance menu on the normal monitoring screen, a test address selection screen on which a selection list of addresses of multiple fire detectors to be tested is arranged, which is generated by screen operation of the test menu on the test screen, a test alarm screen generated by testing a fire detector by screen operation of an address selection on the test address selection screen, and a terminal status screen which displays a list of the status of terminal equipment including at least a fire detector connected to a signal line from the receiver. Therefore, remote screen operation of the receiver screen using a mobile terminal is used, for example, for testing fire detectors performed during construction work or maintenance inspection during operation, and when the mobile terminal is started to be used, the receiver normal monitoring screen is displayed on the mobile terminal, and a test screen and a test address selection screen are displayed as a hidden receiver screen by hierarchical screen operation from the normal monitoring screen, and when a fire detector alarm test is performed in this state, it switches to the test alarm screen, and by remote screen operation of the mobile terminal, fire detector testing can be efficiently performed without having an inspector on the receiver side.

In addition, during the construction work stage, by displaying the terminal status screen as a hidden receiver screen on the mobile terminal of the construction worker, it becomes possible to easily check the connection status of different types of terminals, such as fire detectors and smoke control equipment, to the signal lines from the receiver without having to go to the receiver.

(Effect of avoiding duplication of operation information from mobile devices)
In addition, when operation information from multiple mobile terminals overlaps, the receiver allows at least one of the operation information and suppresses the remaining operation information.Therefore, for example, when multiple inspectors use multiple mobile terminals to operate the remote screen of the receiver to test fire detectors in parallel, confusion caused by overlapping remote screen operations is avoided and remote screen operation of the receiver is possible on a peer-to-peer (one-to-one) basis.

[Disaster Prevention System]
(Outline of fire alarm system)
As shown in FIG. 1, a receiver 10, for example an R type (Record-type) receiver, is installed in a caretaker's room on the first floor of a building in which a fire alarm system is installed, and signal lines 12-1 to 12-3 are pulled out 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, signal line 12-2 is also connected to an addressable transmitter 22 with a transmission function and a unique address set. Furthermore, signal line 12-3 is connected to smoke prevention and exhaust equipment 24, such as fire doors and smoke exhaust devices, via a repeater 16 with a transmission function and a unique address set.

In addition, terminals such as gas leak alarms with transmission functions and unique addresses set, security detectors, and P input terminals (contact input terminals) that transmit contact signals are connected to signal lines 12-1 to 12-3 as necessary, but are not shown in the figure.

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, 256, and terminals including up to 255 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 send 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.

The main CPU 26 is connected to 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 has a reception control unit 52, a screen generation unit 53, and a receiver screen extraction unit 54 as functions realized by executing a program.

The main CPU 26 also stores terminal information regarding 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.

(Reception control)
The reception control during operation of the receiver 10 is as follows. Taking the sub-CPU 30-1 of the sub-CPU board 28-1 as an example, the sub-CPU 30-1 instructs the transmission unit 32-1 to transmit and receive signals to and from the analog fire detector 14 in accordance with a specific communication protocol, thereby performing fire monitoring.

The downstream signal from the transmission unit 32-1 to the analog fire detector 14 is transmitted in voltage mode. This voltage mode signal is transmitted as a voltage pulse that changes the line voltage of the signal line 12-1 between, for example, 18 volts and 30 volts.

In contrast, the upstream signal from the analog fire detector 14 to the transmission unit 32-1 is transmitted in current mode. In this current mode, a signal current flows through the signal line 12-1 at the timing of bit 1 of the transmission data, and the upstream signal is transmitted to the receiver 10 as a so-called current pulse train.

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 has detected the fire, then sends an intra-group search command signal to identify the address of the analog fire detector 14 that has detected the fire, centrally collects analog data from the sensor, and sends it to the main CPU 26 via the serial transfer bus 34.

The reception control unit 52 of the main CPU 26 compares the analog data received from the sub-CPU 30-1 with a predetermined fire determination level (fire threshold), 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 the occurrence of a fire from the speaker of the sound alarm unit 42, displays a fire alert screen on the display 36 including the location of the fire based on the address of the sensor that detected the fire, and further outputs a fire alert signal to the outside via the alert transmission unit 44 to perform predetermined alert 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 device 24 that is the interlocking destination based on the interlocking information set in advance when the reception control unit 52 of the main CPU 26 judges a fire to have occurred.

[Receiver and tablet device screen operations]
(Receiver screen operation section)
A screen generating unit 53 provided in the main CPU 26 of the receiver 10 generates a predetermined screen to be displayed on the display 36. In addition, a receiver screen extracting unit 54 extracts a part of the screen generated by the screen generating unit 53 and displays it.

The screen generation unit 53 generates a relatively large screen, for example, an x coordinate of 1920 x y coordinate of 1080. Of this, the receiver screen extraction unit 54 extracts the area in the range of x coordinate: 0 to 720 and y coordinate: 0 to 480 as the screen to be displayed on the receiver's display 36, which functions as the receiver screen display unit.

The screen generated by the screen generation unit 53 includes display content such as icons and characters, as well as operation elements such as buttons and pull-down menus, and their respective layouts. Each operation element is linked to an operation command corresponding to an operation function.

The receiver 10 has a graphical user interface (GUI), and for example, the display 36 has a touch panel function, and when an operation part on the screen is touched, for example, this touch operation is detected, and a predetermined screen display or processing operation is performed by executing an operation command linked to the touched operation part.

A transmission adapter 45 is connected to the main CPU 26 of the receiver 10, a transmission line 46 is extended from the transmission adapter 45 to the security area, and an access point 48 is connected to the transmission line 46, forming a wireless LAN (wireless local area network) in the monitored area.

In the monitoring area that forms the wireless LAN communication area, for example, there is a tablet terminal 50 carried by a tester who tests an analog fire detector 14, and the receiver 10 and the tablet terminal 50 are connected to each other via a wireless LAN between the access point 48 and a wired LAN via a transmission line 46 from a transmission adapter 45, making it possible to send and receive the necessary information.

(Remote screen operation on tablet devices)
As shown in FIG. 2 , the tablet terminal 50 includes a CPU 57 , a communication unit 58 connected to an antenna 58 a , a display 60 with a touch panel using a liquid crystal display panel or the like, a display unit 62 , and an operation unit 64 .

The CPU 57 is provided with a terminal control unit 66 and a terminal screen extraction unit 68 as functions realized by executing a program. The terminal control unit 66 performs control according to any application program installed on the tablet terminal 50.

The terminal screen extraction unit 68 extracts all areas of the screen received from the receiver 10, for example, x coordinate 1920 x y coordinate 1080, as a screen to be displayed on the terminal display 60, thereby displaying content that includes both content to be displayed on the receiver 10 and content that is not displayed on the receiver 10.

The terminal screen extraction unit 68 extracts an area in the range of x coordinates: 0 to 720 and y coordinates: 0 to 480 from the screen received from the receiver 10, for example, x coordinate 1920 x y coordinate 1080, to create a receiver display content screen that includes the content to be displayed on the receiver 10, and extracts an area in the range of x coordinates: 800 to 1520 and y coordinates: 500 to 980 to create an external receiver display content screen that contains content not to be displayed on the receiver 10, and displays the receiver display content screen and the external receiver display content screen on the display 60 by using different screen arrangements, superimposing the screens, etc.

The tablet terminal 50 has a graphical user interface (GUI), and the display 60, for example, has a touch panel function, and when an operation part on the screen is touched, for example, this touch operation is detected, and a predetermined screen display or processing operation is performed by executing an operation command linked to the touched operation part. The basic principle is that the screen of the receiver 10 can be remotely operated by, for example, touching operation parts such as icons, buttons, pull-down menus, etc. arranged on the displayed screen.

In addition, because the tablet terminal 50 displays an area that is not displayed on the receiver, by performing operations in that area, it is possible to remotely operate the screen of the receiver 10 from the tablet terminal 50 while maintaining the screen display of the receiver 10. This realizes a remote graphical user interface function unique to this embodiment, in which remote screen operation of the tablet terminal 50 does not monopolize the screen operation of the receiver 10 and cause it to switch automatically, or prevent screen operation on the receiver 10, making it possible to simultaneously operate the screen of the receiver 10 itself and remotely operate the screen of the receiver 10 from the tablet terminal 50.

(Receiver and tablet device screen operation functions)
FIG. 3 is an explanatory diagram showing a functional configuration of screen operation for remotely operating the screen of the receiver using a tablet terminal.

As shown in FIG. 3, the screen operation function on the receiver 10 side is composed of a receiver control unit 52, a screen generation unit 53, a receiver screen extraction unit 54, an operation input reception unit (GUI) 51, and a screen storage unit 55, and the screen generation unit 53 is connected to the receiver control unit 52. Note that the communication unit 56 indicates the communication system of the wired LAN and wireless LAN composed of the transmission adapter 45, the transmission line 46, and the access point 48 shown in FIG. 1.

The screen generation unit 53 generates a screen based on a control command from the receiver control unit 52. The screen format is stored in the screen storage unit 55, and the screen generation unit 53 generates a screen in which various information, such as the location of the fire, has been added to the screen format to be displayed.

The receiver screen extraction unit 54 extracts a predetermined area from the screen generated by the screen generation unit 53 as the receiver screen to be displayed on the receiver's display, and displays it on the display 36.

The operation input reception unit 51 is, for example, a touch panel, and acquires operation information including operation coordinate information for operations on the receiver display 36. The operation information is transmitted to the receiver control unit 52, and the receiver control unit 52 changes the screen via the screen generation unit 53 based on the operations.

The screen memory unit 55 stores and manages, for example, a normal monitoring screen 70, a fire alarm screen 72, a maintenance screen 74, a test management screen 76, a test address selection screen 78, a test alarm screen 80, and a terminal status screen 82 as screen formats.

Operation elements such as icons, buttons, and pull-down menus are arranged as necessary on the normal monitoring screen 70, fire alarm screen 72, maintenance screen 74, test management screen 76, test address selection screen 78, test alarm screen 80, and terminal status screen 82, and each operation element is linked to an operation command that executes the corresponding operation content. For example, when an operation element is touched, the linked operation command is executed, and for example, the next operation screen created hierarchically is displayed or a control operation is performed.

On the other hand, the remote screen operation function on the tablet terminal 50 side is composed of a communication unit 58, a terminal control unit 66, a terminal screen extraction unit 68, and a terminal operation input reception unit (GUI) 69, and the communication unit 58 is connected to the terminal control unit 66. In addition, the terminal screen extraction unit 68 is provided with the functions of a receiver display content screen extraction unit 68a and an outside-receiver display content extraction unit 68b.

Based on the screen generated by the receiver 10, the receiver display content screen extraction unit 68a extracts the content of the screen including the portion to be displayed on the display 36 as the current screen that becomes the receiver display content screen, and displays it on the display 60.

The receiver external display content screen extraction unit 68b extracts content based on the portion of the screen generated by the receiver 10 that is not to be displayed on the display 36 as a hidden screen that becomes the receiver external display content screen, and displays it on the display 60.

In the following explanation, the functions of the receiver display content screen extraction unit 68a and the receiver external display content extraction unit 68b will be collectively explained as the functions of the terminal screen extraction unit 68.

The terminal screen extraction unit 68 is executed by the CPU 57 of the tablet terminal 50, and when there is no communication connection to the receiver 10, the receiver display content screen and the receiver external display content screen are not displayed. When there is a communication connection to the receiver 10, the receiver display content screen and the receiver external display content screen are displayed.

Operational elements such as icons, buttons, and pull-down menus are displayed on the receiver display content screen and the external receiver display content screen, but there is no link to the corresponding operation commands and these are simply display parts.

When the normal monitoring screen 70, which is the current screen of the receiver 10, is displayed on the display 60 and an operation part such as an operation button is touched, the terminal operation input reception part (GUI) 69 detects coordinate information indicating the screen operation position of the touched operation part and transmits this as operation information to the receiver 10.

When the screen generation unit 53 of the receiver 10 receives coordinate information (operation information) indicating the screen operation position of the touched operation part from the tablet terminal 50, it determines that an operation of the corresponding coordinate on the screen has been received based on this coordinate information, and executes the operation command linked to the operation part.

The receiver 10 changes the receiver screen, and the communication unit 56 of the receiver 10 transmits screen information to the tablet terminal 50 at any time, and the terminal screen extraction unit 68 of the tablet terminal 50 changes the receiver display content screen.

Of the screens generated by the screen generation unit 53 of the receiver 10, the area corresponding to the external receiver display content screen is normally blank, and the display content can be selected. By performing a specified screen call operation on the external receiver display content screen of the tablet terminal 50, the specified content is drawn in the area corresponding to the external receiver display content screen based on the screen format stored in the screen memory unit 55, and is displayed on the external receiver display content screen of the tablet terminal 50.

When any operation part on the newly displayed external receiver display content screen on the tablet terminal 50 is touched, coordinate information (operation information) indicating the screen position of the touched operation part is detected and transmitted to the receiver 10, just as in the case of the receiver display content screen, and the screen generation unit 53 of the receiver 10 determines the screen operation of the operation part arranged on the hidden screen based on the received coordinate information, executes the operation command linked to the operation part, generates another hidden screen corresponding to the operation part, transmits it to the tablet terminal 50, and displays it together with the currently displayed receiver display content screen of the receiver 10.

Here, transmitting (sending) a screen from the receiver 10 to the tablet terminal 50 means reading out screen data stored in the display memory of the receiver 10 corresponding to the display format of the display 36 in order to display it on the display 60, and transmitting it to the tablet terminal 50. Note that if the display formats used by the receiver 10 and the tablet terminal 50 differ, the tablet terminal 50 will convert it to its own display format.

[Receiver display screen]
The normal monitoring screen 70, fire alert screen 72, maintenance screen 74, test management screen 76, test address selection screen 78, test alert screen 80, and terminal status screen 82 stored in the screen memory unit 55 of the receiver 10 in Figure 3 will be explained as follows.

(Normal monitoring screen)
4A shows an example of a normal monitoring screen. The normal monitoring screen 70 is a screen displayed during operation of the fire alarm system, and following the status display of "normal operation", there are an operation button 70a for "disconnecting device startup/stopping transmission of information", an operation button 70b for "stopping area sound", and an operation button 70c for "maintenance (construction)".

(Fire alarm screen)
4B shows an example of a fire alert screen. The fire alert screen 72 displays "Fire" as a title 72a, followed by fire information 72b showing the location of the fire, and a fire response message 72c followed by a fire confirmation button 72d, a non-fire confirmation button 72e, and an overall view button 72f showing the location of the fire.

(Maintenance screen)
Fig. 5(A) shows an example of a maintenance screen. When the operation button 70c of the normal monitoring screen 70 shown in Fig. 4(A) is touched, the maintenance screen 74 of Fig. 5(A) is switched to and displayed. The maintenance screen 74 has a test button 74a, a terminal status button 74b, a fault information button 74c, a history button 74d, and a property information button 74e, and further has a return button 74f.

(Exam management screen)
Fig. 5(B) shows an example of a test management screen. When a test button 74a on the maintenance screen 74 shown in Fig. 5(A) is touched, the test management screen 76 shown in Fig. 5(B) is displayed. On the test management screen 76, following a test message 76a, an address selection button 76b, a district name selection button 76c, and a map selection button 76d are arranged, making it possible to select a fire detector to be tested from the address, district name, or map.

(Test address selection screen)
Fig. 6A shows an example of a test address selection screen. When the address selection button 76b on the test management screen 76 shown in Fig. 5B is clicked, the test address selection screen 78 of Fig. 6A is displayed.

The test address selection screen 78 displays a test message 78a followed by a test address selection list 78b. The test address selection list 78b has the items Selection, Address, Type, and Test Result. Addresses 001 and 002 have already been tested with the test results being "normal." Next, address 003 will be tested. By touching the radio button to select, the color of the list column changes as shown by the shaded area, indicating that the test address has been selected.

(Test notification screen)
Fig. 6(B) shows an example of the test alarm screen. When a fire detector is tested based on the operation of the test address selection screen 78 shown in Fig. 6(A), a test alarm screen 80 shown in Fig. 6(B) is displayed based on the fire signal from the test fire detector.

In addition to the title 80a "There is a fire," the test alert screen 80 displays a test alert 80b, and indicates the test alert location using fire information 80c. This is followed by a test response message 80d and a test confirmation button 80e.

Here, to test a fire detector by operating the test address selection screen 78 in FIG. 6(A), the receiver 10 shown in FIG. 1 sends a test signal specifying the address for which the test command was received, for example to signal line 12-1, and a simulated fire alarm operation is performed in the analog fire detector 14 with a matching address connected to signal line 12-1, and a test alarm signal is sent to the receiver 10.

In addition to testing fire detectors using test signals from the receiver 10, there is also a scorching test, which is performed by actually introducing smoke into the fire detector using a test tool. During the scorching test, the normal monitoring screen 70 of the receiver 10 is switched to a test alert screen 80 when the fire detector issues a test alert, and on the tablet terminal 50, the normal monitoring screen 70, which is the current screen of the receiver 10, is switched to the test alert screen 80 when the test alert is issued. This allows the test alert operation of the receiver 10 for the scorching test to be confirmed using the remote screen operation function of the tablet terminal 50, even if a separate tester is not present at the receiver 10.

(Device status screen)
Fig. 7 shows an example of a terminal status screen for a fire detector, etc. When the terminal status button 74b on the maintenance screen 74 shown in Fig. 5(A) is touched, a terminal status screen 82 shown in Fig. 7 is displayed. The terminal display screen 82 displays a terminal designation section 82a and a terminal status list 82b.

In the terminal designation section 82a, there are arranged radio buttons for designating terminals or terminal status such as fire alarm, smoke control, interlocking, terminal failure, etc. Here, the fire alarm and smoke control radio buttons are operated by touch, and in response, information showing the terminal status of the fire detectors and fire doors is displayed in the terminal status list 82b, for example in address order, and any parts not displayed can be displayed by scrolling, allowing the status of the required terminal device to be confirmed.

Note that the normal monitoring screen 70, fire alarm screen 72, maintenance screen 74, test management screen 76, test address selection screen 78, test alarm screen 80, and terminal status screen 82 are just examples, and many other screens are generated and prepared for use in fire monitoring, maintenance inspections, etc.

[Tablet device screen layout]
FIG. 8 is an explanatory diagram showing the screen layout of a tablet terminal, and FIG. 9 is an explanatory diagram showing the screen layout of the tablet terminal subsequent to FIG.

Figure 8 (A) shows an embodiment of the screen layout of a current screen 84 and a hidden screen 86 displayed on the display 60 of a tablet terminal 50, where a hidden screen 86 received by remotely operating the screen of the receiver 10 is placed in the free space of the current screen 84 that is the same as the current screen 84 currently displayed on the receiver 10 and displayed on the display 60. This screen layout is effective when the screen size of the display 60 of the tablet terminal 50 is sufficiently large compared to the display 36 of the receiver 10.

In FIG. 8(B), the screen of the display 60 of the tablet device 50 is divided into two screens, left and right, with the current screen 84 located on one side and the hidden screen 86 located on the other. This allows the hidden screen 86 to be reliably displayed without being obstructed by the current screen 84.

In FIG. 8(C), a current screen 84 and a hidden screen 86 are arranged on the screen of the display 60 of the tablet terminal 50, overlapping partially from front to back, and when the hidden screen 86 located in the back is touched, the hidden screen 86 becomes the front screen. This makes it possible to display the current screen 84 and hidden screen 86 by making full use of the screen size, even if the screen sizes of the receiver 10 and the tablet terminal 50 are approximately the same.

In FIG. 9(A), the screen of the display 60 of the tablet terminal 50 is divided into four screens, one of which is used as a current screen 84, and the remaining three are used as hidden screens 86. This allows the hidden screens displayed hierarchically to be viewed as a whole, and allows easy operation of the higher-level hidden screen without having to switch screens from a lower-level hidden screen to a higher-level hidden screen.

Figure 9 (B) shows another example of a dual-screen display, in which a current screen 84 is placed in a small area, for example in the upper left corner, of the display 60 of the tablet device 50, and a hidden screen 86 is placed in the remaining large area, allowing the hidden screen 86 to be displayed as the main screen.

Figure 9 (C) is an example of an expanded display of the current screen, where the current screen 84 is placed in most of the screen of the display 60 of the tablet terminal 50, for example an area that occupies 90% vertically and horizontally, and the remaining narrow areas at the bottom and right edge can be used to display an expanded view of content that is not displayed on the receiver screen.

[Screen operation control behavior]
FIG. 10 is an explanatory diagram showing the control operation of screen operation by the receiver and the tablet terminal, and FIG. 11 and FIG. 12 are explanatory diagrams subsequent to FIG. 10 showing the control operation of screen operation by the receiver and the tablet terminal.

As shown in FIG. 10, the receiver 10 secures an area (drawing area) of, for example, x coordinate (0-1920) x y coordinate (0-1080) in memory as a display screen memory area 88, within which an area of, for example, x coordinate (0-720) x y coordinate (0-480) is set as a current screen memory area 90, and an area of, for example, x coordinate (800-1520) x y coordinate (500-980) is set as a hidden screen memory area 92, with the normal monitoring screen 70 stored in the current screen memory area 90, while the hidden screen memory area 92 is a blank screen 71 on which only an appropriate mark, for example, a cursor 94, is placed.

At this time, the normal monitoring screen 70 stored in the screen memory area 90 is extracted and displayed on the display 36 of the receiver 10. When the tablet terminal 50 is turned on with the receiver 10 in this screen display state and a communication connection with the receiver 10 is established by a specified operation, the normal monitoring screen 70 and blank screen 71 stored in the receiver 10 are transmitted to the tablet terminal 50, and if, for example, a two-screen display is set on the display 60 of the tablet terminal 50 as shown in FIG. 8(C) where the two screens are shifted forward and backward and overlap each other, the normal monitoring screen 70 is extracted and displayed as the current screen 84, and the blank screen 71 is extracted and displayed as the hidden screen 86.

Next, by clicking on the blank screen 71 to make it the previous screen, and then clicking the cursor 94, a dialogue 96 opens for selecting, for example, a hidden screen. The dialogue 96 lists a selection menu of various screens stored in the screen storage unit 55 of the receiver 10 shown in FIG. 3. When, for example, "Maintenance scene" is selected in the dialogue 96, a hidden screen display request specifying the maintenance screen is sent to the receiver 10 in process 98.

When the receiver 10 receives a hidden screen display request specifying a maintenance screen from the tablet terminal 50 in process 100, it generates a maintenance screen 74 and stores it in the hidden screen memory area 92, and in process 102, based on periodic screen update processing, transmits information about the entire screen including the maintenance screen 74 to the tablet terminal 50, and the tablet terminal 50 extracts and displays the received maintenance screen 74 on the hidden screen 86 of the display 60.

Next, when the test button on the maintenance screen 74 is touched on the tablet terminal 50, processing 104 detects the touch operation of the test button and transmits coordinate information indicating the screen operation position to the receiver 10.

In process 106, the receiver 10 receives coordinate information from the tablet terminal 50, and as shown in FIG. 11, detects the screen operation position in the maintenance screen 74 stored in the hidden screen memory unit 92, generates a hidden screen such as a test management screen 76 and stores it in the hidden screen memory area 92, transmits the test management screen 76 to the tablet terminal 50, and the tablet terminal 50 extracts and displays the received test management screen 76 on the hidden screen 86 of the display 60.

Next, when the address selection button on the test management screen 76 is touched on the tablet terminal 50, processing 110 detects the touch operation of the address selection button and transmits coordinate information indicating the screen operation position to the receiver 10.

In process 112, the receiver 10 receives coordinate information from the tablet terminal 50, detects the screen operation position in the test management screen 76 stored in the hidden screen memory unit 92, generates, for example, a test address selection screen 78 and stores it in the hidden screen memory area 92, and in process 113, based on periodic screen update processing, transmits information about the entire screen including the test address selection screen 78 to the tablet terminal 50, and the tablet terminal 50 extracts and displays the received test address selection screen 78 on the hidden screen 86 of the display 60.

Next, when the test address on the test address selection screen 78 is touched on the tablet terminal 50, coordinate information indicating the screen operation position of the test address selected in process 114 is transmitted to the receiver 10.

The receiver 10 receives coordinate information from the tablet terminal 50 in process 116, detects the test address in process 118, and transmits a test signal specifying the address of the fire detector to perform a remote test of the fire detector. In process 120, it receives a fire signal from the fire detector that has issued a test alert in this remote test of the fire detector, generates a test alert screen 80 and stores it in the hidden screen memory area 92, and transmits the information of the entire screen including the test alert screen 80 to the tablet terminal 50 in process 122 of FIG. 12 based on periodic screen update processing, and the tablet terminal 50 extracts and displays the received test alert screen 80 on the hidden screen 86 of the display 60.

Then, the confirmation button or back button on the test alert screen 80 is selected by touching the tablet terminal 50, and coordinate information indicating the screen operation position of the selected confirmation button or back button in process 124 is sent to the receiver 10, and the process returns to process 112, and the same process is repeated as desired.

In addition, if the receiver 10 determines that there is a fire during testing, the receiver 10 and the tablet terminal 50 display a fire alert screen 72 on the current screen 84, and the test work can be stopped to deal with the fire, for example.

Figure 13 is a time chart showing the control operations of screen operation by the receiver and tablet terminal. As shown in Figure 13, during operation, the receiver 10 generates and stores a normal monitoring screen in the current screen memory area in step S1, generates and stores a blank screen with a cursor in the hidden screen memory area in step S2, and extracts and displays the normal monitoring screen stored in the current screen memory area on the display 36 in step S3.

In this state, when the tablet terminal 50 makes a communication connection request to the receiver 10 through a predetermined operation in step S4, the receiver 10 transmits the normal monitoring screen and a blank screen to the tablet terminal 50 in step S5, and the tablet terminal 50 extracts and displays the normal monitoring screen as the current screen on the display 60 in step S6, and extracts and displays the blank screen with the cursor as the hidden screen.

Next, when a specific operation is performed on the blank screen on the tablet terminal 50, for example, by clicking the cursor to open a dialog box and request the display of the hidden screen that is to be displayed, the operation requesting the display of the hidden screen is determined in step S7, and a request to display the hidden screen is sent to the receiver 10 in step S8.

When the receiver 10 receives a hidden screen display request from the tablet terminal 50, in step S9 it generates the requested hidden screen and stores it in the hidden screen storage area, and also transmits the information of the entire screen to the tablet terminal 50, and in step S10 the tablet terminal 50 extracts and displays the hidden screen received from the receiver 10 on the display 60.

Next, when the tablet terminal 50 determines in step S11 that a screen operation has been performed by touching any operation part arranged on the hidden screen of the displayed receiver 10, in step S12 it detects coordinate information (operation information) indicating the operation position of the touched operation part and transmits it to the receiver 10.

In step S13, the receiver 10 determines the screen operation of the operation part specified by the coordinate information for the hidden screen stored in the hidden screen memory area based on the coordinate information (operation information) received from the tablet terminal 50, generates a hidden screen corresponding to the screen operation, stores it in the hidden screen memory area, and transmits it to the tablet terminal 50, and in step S14, the tablet terminal 50 extracts and displays the new hidden screen received on the hidden screen of the display 60.

Then, by operating the hidden screen on the tablet device 50 as necessary, the receiver 10 generates and transmits a new hidden screen corresponding to the screen operation, thereby repeating the remote display and operation of the hidden screen.

[Avoiding overlapping remote screen operations]
In this embodiment, when screen operation requests (operation information) from multiple tablet terminals 50 to the receiver 10, i.e., when communication connections from multiple tablet terminals 50 overlap, the receiver 10 permits one of the screen operation requests (operation information) and suppresses the remaining screen operation requests (operation information). This makes it possible to avoid confusion due to overlapping remote screen operations when remotely operating the screen of the receiver 10 using multiple tablet terminals 50, and enables remote screen operation of the receiver 10 on a peer-to-peer (one-to-one) basis.

Priorities may be set in advance for remote screen operation requests (operation information) from multiple tablet terminals 50, and requests with higher priorities may be permitted. In addition, the receiver 10 may be provided with a function for generating a virtual receiver screen extraction unit 54, so that remote screen operation requests from multiple tablet terminals can be accepted and processed in parallel.

[Screen generation by server]
In the above embodiment, as shown in FIG. 1, a screen generation unit 53 is provided in the receiver 10 to generate a specific screen required for fire monitoring of the fire alarm system, and the screen is displayed on the receiver 10 and the tablet terminal 50. However, the receiver 10 may be communicatively connected to an external support server via a communication network such as the Internet, a screen generation unit 53 may be provided in the support server to generate a specific screen required for fire monitoring of the fire alarm system, the generated screen may be transmitted to the receiver 10 and displayed on the receiver screen extraction unit 54, and the screen may also be transmitted from the receiver 10 to the tablet terminal 50 for display.
