Further, the fire prevention door D111, the smoke exhauster D112, the shutter D113, and the leaning wall D114 are connected to the smoke prevention control relay D11. With such a configuration, the fire receiver 20 collects information from various sensors and the like installed at various predetermined locations. When the collected information includes fire information, the fire receiver 20 issues a fire alarm and transmits a control command to the smoke-proof control relay D11, etc. Operate to prevent fire spread.

  Here, attention is paid to the ATF sensors (corresponding to C111 to C114 and C121 to C124 in FIG. 1) and the sensor repeater C11 installed in various places. In this case, the fire receiver 20 is provided in the uppermost layer, the sensor repeater C11 is provided in the middle layer, and a plurality of ATF detectors are provided in the lower layer, thus forming a hierarchical structure.

  Further, a plurality of ATF sensors arranged in the lower layer are grouped for each sensor line. In FIG. 1, the case where it is grouped into two sensor lines of C111-C114 and C121-C124 is illustrated.

  The fire receiver 20 according to the present invention is technically characterized in that an abnormality occurrence location can be easily displayed in units of sensor lines drawn from the repeater. Therefore, the technical features of the present application will be described in detail below, taking as an example a hierarchical structure including the sensor repeater C11 and each ATF sensor.

  FIG. 2 is a configuration diagram of the fire receiver according to the first embodiment of the present invention, which is grouped into a top layer fire receiver 20, a middle layer sensor repeater C11, and two sensor lines. A plurality of ATF sensors are provided.

The fire receiver 20 in FIG. 2 includes a control unit 21, a display operation unit 22, a storage unit 23, and a transmission / reception unit 24. The sensor repeater C11 includes a control unit 31, a transmission / reception unit 32, a sensor line L1 transmission / reception unit 33a, and a sensor line L2 transmission / reception unit 33b. Further, the ATF detectors grouped and connected to the sensor line L1 and the sensor line L2 are composed of 30 serial numbers 1 to 30, respectively.

  First, communication between the sensor repeater C11 and each ATF sensor will be described with reference to FIG. 2, and then communication between the fire receiver 20 and the sensor repeater C11 will be described. To do.

[Communication between sensor repeater C11 and each ATF sensor]
Communication during this time is performed by the control unit 31 with each ATF sensor via the sensor line L1 transmission / reception unit 33a and the sensor line L2 transmission / reception unit 33b in the sensor repeater C11. At this time, the control unit 31 performs communication control for each grouped sensor line (that is, for each of the sensor line L1 transmission / reception unit 33a and the sensor line L2 transmission / reception unit 33b).

  In order to collect the status of a plurality of ATF sensors connected to each other, the sensor repeater C11 makes an inquiry to each ATF sensor in the group, with some units as one group. As an inquiry, the sensor repeater C11 transmits a status information request command to return status information to the ATF sensor. The sensor repeater C11 transmits a reference pulse at a predetermined interval by the number of ATF sensors grouped after the transmission of the status information request command.

  On the other hand, in response to the inquiry, each ATF sensor receives the state information by a signal having a predetermined pulse width corresponding to its own state following the reference pulse transmitted by the sensor repeater C11 corresponding to its own address. Return (report) to the sensor repeater C11. By receiving a pulse signal specific to each ATF sensor, the sensor repeater C11 can collect the state of each ATF sensor.

  Here, the detector repeater C11 is in a normal state if the pulse signal of the notification signal from the ATF sensor is, for example, a 2 ms wide pulse signal, and if it is a 4 ms wide pulse signal, the detector repeats a fire. When the sensor to be detected is determined to be in an abnormal state and the output value is in an abnormal state, and there is no pulse signal from the ATF sensor, there is no response in which the ATF sensor is removed or cannot communicate. Judge. The inquiry from the sensor repeater C11 to each ATF sensor may be made periodically by the sensor repeater C11 or in accordance with a command from the fire receiver 20.

The communication during this time is performed by the respective control units 21 and 31 via the respective transmission / reception units 24 and 32.

(1) About a normal communication method The fire receiver 20 is provided in the middle layer and communicates with each terminal device in order to collect state information of each terminal device (see FIG. 1) connected to the signal line SG. As part of this, communication is also performed with the sensor repeater C11. On the other hand, the sensor repeater C11 is connected to a plurality of ATF sensors grouped for each sensor line (see FIG. 1).

The fire receiver 20 can collect state information of the terminal device with each terminal device such as the sensor repeater C11 by the following three methods.
(Method 1) Point polling The fire receiver 20 sends a status information request command to the terminal devices as a group, in order to collect the status of a plurality of connected terminal devices including the sensor repeater C11. Send. On the other hand, each terminal device measures the timing according to its own address in response to the status information request command, and reports the status information to the fire receiver 20. The fire receiver 20 repeatedly performs communication with such a group and collects status information of all terminal devices.

  Here, the status information of the sensor repeater C11 includes the status information of the sensor repeater C11 itself, and all the ATF sensors connected to the sensor line are normal or an abnormal ATF. Contains information on whether a sensor is present.

  The fire receiver 20 designates an individual address assigned to each ATF sensor, and repeatedly inquires each ATF sensor for each ATF sensor via the sensor relay C11. Then, each ATF sensor may measure the timing according to its own address in response to the inquiry, and report the status information to the fire receiver 20 via the sensor relay C11.

(Method 2) Selecting The fire receiver 20 designates an address corresponding to a desired terminal device and transmits a predetermined control command to control the terminal device, or transmits status information or the like to the desired terminal device. Request commands can be sent to collect status information from individual terminal devices. The terminal device to which the address is specified notifies the fire receiver 20 of the control result or the requested status information in response to the control command.

(Method 3) System polling The fire receiver 20 can control each terminal device by transmitting a common control command to all the terminal devices. Here, as control commands by system polling, for example, a fire recovery command (command to restore the sensor or repeater that output a fire signal to a normal monitoring state), a district sound stop command (a ringing district bell) Command to stop).

(2) Collection of information on occurrence of abnormality The fire receiver 20 has information on the state of occurrence of abnormality in the state information of the sensor repeater C11 collected by point polling (there is an ATF sensor in which an abnormality has occurred). Is included, the abnormal state information request (selecting) is transmitted to the transmitter relay C11 of the transmission source, and the serial number of the abnormal ATF sensor and the abnormal information ( Collect no response, abnormal output value, etc.).

  In this way, the fire receiver 20 has a plurality of ATF detectors connected to each detector (detector repeater C11 in FIG. 2) via a repeater (corresponding to the detector repeater C11 in FIG. 1). Status information) can be acquired.

  As described above, the fire receiver 20 according to the present invention is technically characterized in that an abnormality occurrence place is displayed in an easily understandable manner in units of sensor lines. Then, next, the screen displayed on the display operation part 22 of the fire receiver 20 is demonstrated concretely.

  First, a specific screen layout will be described. 3 and 4 are diagrams showing an example of a screen layout displayed on the display operation unit of the fire receiver according to Embodiment 1 of the present invention. Here, the case where the notification display of 30 ATF detectors of serial numbers 01 to 30 connected to the detector line L1 is performed based on the configuration shown in FIG. 2 is illustrated.

  FIG. 3 shows a screen layout displayed when the “serial number” button is operated when an abnormality occurs in the ATF sensor. The “monitor line abnormality” sub-screen (corresponding to the first sub-screen) shown in the upper part of FIG. 3 displays the address information and the sensor line information of the repeater that has reported the abnormality occurrence state, and for display switching. A “sequential number” button (corresponding to a first switching button) is displayed as a button.

  Then, when the “sequence number” button is pressed, a sub screen (corresponding to the second sub screen) of the “sequence number list” in the lower row is displayed. In this “sequential number list”, the serial numbers of ATF sensors that have been “no response” and the serial numbers of ATF sensors that have been notified of “abnormal output value” are listed.

  Furthermore, a “detail” button (corresponding to a second switching button) and a “delete” button are provided at the upper right of the “sequence number list” window. When the “Erase” button is pressed, the “Sequential Number List” sub-screen disappears. On the other hand, when the “detail” button is pressed, the detailed information of the ATF sensor that has reported “no response” or “abnormal output value” as shown in FIG. 4 (corresponding to the third sub-screen) Is displayed. As shown in FIG. 4, by displaying the detailed message corresponding to the serial number, the operator can easily grasp the place where the abnormality has occurred.

  In this embodiment, the abnormality display of the “sequence number list” of the ATF sensor is performed in units of sensor lines, but the abnormality display may be performed in units of a plurality of sensor lines or repeaters. In that case, the address information of the repeater that has reported the error occurrence status is displayed on the “monitor line abnormality” sub-screen (first sub-screen), and the “sequence number list” sub-screen (second sub-screen) The number of the ATF sensor that was “no response” and the sequence number of the ATF sensor that was “abnormal output value” for all or all of the sensor lines of the repeater The detailed message corresponding to the sensor line and the serial number is displayed in the detailed information (third sub-screen).

  Also, when the “Serial number” button is pressed on the “Monitor line error” sub-screen (first sub-screen), the “Sequential number list” sub-screen (second sub-screen) is not displayed, and detailed information is displayed. (Third sub-screen) may be displayed.

  Next, data serving as a base for performing the display as shown in FIGS. 3 and 4 will be described.

The standard database and the additional database can be aggregated as one database.

  FIG. 5 is an explanatory diagram of a standard database included in the fire receiver according to Embodiment 1 of the present invention. “Address” in the leftmost column indicates address information of each terminal device. The sensor repeater C11 shown in FIG. This address is a unique number assigned so that the sensor or repeater to be communicated can be specified when the fire receiver communicates with the sensor or repeater.

  The “line” in the second column from the left indicates the sensor line that each repeater has. The sensor lines L1 and L2 shown in FIG. 2 correspond to the lines 01 and 02 corresponding to the address 11. This line number is a number assigned to the sensor line for connecting a plurality of ATF sensors to the repeater, and is used to identify which sensor line has a fire / abnormality. .

  “Option message” in the third column from the left indicates message information corresponding to each address or sensor line. The “option message” corresponds to data such as a place name that is displayed so that the place of occurrence can be easily understood together with address information and line number information when various displays are performed.

  Further, the rightmost column “serial number” is a registration result of the connected ATF sensor, and indicates that the serial number ATF sensor displayed as ◯ is connected. By registering the serial number of the ATF sensor that is actually connected, the connection state of the lower layer can be specified for each sensor line of the repeater.

  The operator sets data in this standard database according to the configuration of each terminal device connected to the fire receiver and each ATF sensor connected to each repeater. The serial number list shown in FIG. 3 can be displayed based on the setting data of the standard database.

  Next, FIG. 6 is an explanatory diagram of an additional database that the fire receiver according to Embodiment 1 of the present invention has. The “address” in the leftmost column and the “line” in the second column from the left are the same as those in FIG. “Serial number” in the third column from the left indicates the serial number of the ATF sensor connected to each sensor line, and corresponds to the serial number in FIG.

  Further, “Option message” in the rightmost column indicates message information to be displayed corresponding to each serial number. The operator sets data in this additional database according to the installation location of each sensor. Based on the setting data of the additional database, detailed display corresponding to each serial number shown in FIG. 4 is possible. As described above, an option message for the address / line of the standard database and the serial number of the ATF sensor is set on the additional database.

  Therefore, by providing the standard database and the additional database, message information such as the installation location can be displayed together with the serial number (address number) of the ATF sensor. As a result, it is possible to display the location of the abnormality in an easy-to-understand manner for each sensor line. Furthermore, when message information such as the location of the ATF sensor is not required, an additional database is not required, and the capacity of the storage unit can be reduced.

  Further, when message information corresponding to each sensor is not registered in the additional database, the control unit 21 may prohibit switching to detailed information (third sub-screen) for displaying the message information. it can. As a method of prohibiting switching, the button for switching to detailed information (third sub-screen) may not react even if the button is operated, or the button operation is prohibited by a color different from other buttons. May be displayed, or the button may not be displayed. Furthermore, by making it possible to edit data on the standard database or the additional database from the display operation unit 22, message information and the like can be easily edited on site.

  As described above, according to the first embodiment, when displaying an abnormal sensor in units of sensor lines, message information uniquely assigned to each sensor can be displayed together. It is possible to obtain a fire receiver that can easily display an abnormality occurrence place in units of sensor lines.
