Description

  The present invention relates to a fire alarm facility, and more particularly to a fire indicator.

  An address is assigned to a terminal device such as a sensor or a repeater, and the fire receiver has a fire alarm facility that transmits information based on the address of the terminal device and collects information on a fire or failure (for example, see Patent Document 1). ).

  In addition, when a signal related to disaster prevention such as a fire or failure is received at the receiver, the fire receiver reads the data of the ridge / floor / district representing the district name corresponding to the signal from the ROM and transmits it to the fire indicator. However, the fire indicator has received and displayed the data (for example, see Patent Document 2).

  As described above, the user using the building can easily determine the location where the abnormality such as a fire has occurred from the district name displayed on the fire display device other than the fire receiver.

JP-A-8-255294 JP-A-6-96376

  The display with the district name is easy for the user to understand. However, if multiple terminal devices are installed in one district, the fire indicator can be used when any installed terminal device emits a signal. The same district name is displayed on the screen, and the partition name is changed if the partition to which the terminal device belongs is changed due to reasons such as the partition being changed. In order to do this, even if a fire indicator was installed near the terminal device that emitted the signal, it was necessary to go to the fire receiver for confirmation.

  The present invention has been made to solve the above-described problems, and the fire display device includes display switching means for displaying either or both of the district name data and the address data. In normal use, the area data (building area) is displayed on the fire indicator, so the user can easily identify the location of the fire, and the address data is displayed on the fire indicator during maintenance. Therefore, it is an object of the present invention to be able to easily determine the installation location of the terminal device that is maintained by the maintenance worker at a location other than the fire receiver.

A fire alarm facility according to the present invention includes a plurality of terminal devices each assigned an address, a fire receiver that performs signal transmission based on the addresses with the plurality of terminal devices, and a signal transmitted from the fire receiver. In a fire alarm facility consisting of a fire indicator that performs display based on the fire alarm, when a fire or failure signal is received from a terminal device, the fire device is a unique number that does not overlap the terminal device and changes transmission and fire receiver display operation unit which displays a district name of potential overlap and changes corresponding to the address and the address is not to be, at least address and district name of the terminal device to the fire indicators comprising a transmitting unit for displaying machine for fire indicators includes a display unit, address Suma other area name transmitted from the fire receiver in the display unit, or both addresses and district name Those having a display switching means for Shimesuru.

  Because the fire indicator has display switching means for displaying either or both of the district name data and address data, the district data (building floor district) can be displayed with the fire indicator during normal use. Because it is displayed, the user can easily determine the location of the fire, etc., and during maintenance, the address data is displayed on the fire indicator. The installation location can be easily identified.

  When the user and the maintenance worker confirm the terminal device together, the user and the maintenance worker can easily determine the installation location of the terminal device by displaying both.

  In addition, since the district name data and address data are sent from the fire receiver to the fire indicator, it is not necessary to set the district name data in the fire indicator storage section of the fire indicator, so the district name data can be changed by changing the partition. All you have to do is change the fire receiver data.

  In addition, since only the address data of the terminal device received from the fire receiver is transmitted and the district name data corresponding to the address data is read from the fire indicator storage unit by the fire indicator, the fire receiver and the fire indicator are The communication load can be reduced.

  In addition, even if the maintenance worker forgets to return the display, the fire indicator automatically returns to the district name data display after a predetermined time has elapsed, so that the user is not confused.

(Communication operation between fire receiver and terminal device)
Communication performed between the fire receiver FA and the terminal device will be described.
The terminal device is set with an address that is a unique number that does not overlap. The fire receiver FA identifies a terminal device by its address and performs communication.

  In FIG. 1, the numeral part of the reference numeral attached to the terminal device indicates the address number. For example, address 1 is set for the photoelectric analog sensor AD1, and address 10 is set for the thermal analog sensor AD10. Is set.

  The fire receiver FA communicates with each terminal device in order to collect state information of each terminal device (see FIG. 1) connected to the signal line SG.

  The fire receiver FA can collect state information of the terminal device and control the terminal device and the like by the following three methods with each terminal device.

(1) Point polling The fire receiver FA transmits a status information request command to a terminal device by collecting several units as a group in order to collect the status of a plurality of connected terminal devices. 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 FA. The fire receiver FA repeatedly performs communication with such a group at predetermined intervals, and collects status information of all terminal devices.

(2) Selecting The fire receiver FA designates an address corresponding to a desired terminal device and transmits a predetermined control command to control the terminal device, or requests status information from the desired terminal device. Commands can be sent and status information can be collected from individual terminal devices. In response to the control command, the terminal device to which the address is designated reports the control result to the fire receiver FA or reports the requested status information.

(3) System polling The fire receiver FA 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 (for ringing district sound) Command for stopping the repeaters AD19 to AD24).

(Communication operation between fire receiver and fire indicator)
Communication performed between the fire receiver FA and the fire indicator DP will be described.

  The fire receiver FA communicates with the fire indicator in order to collect state information of the fire indicator DP (see FIG. 1) connected to the signal line DG.

  The fire receiver FA collects the status information of the fire indicator DP with the fire indicator DP by the following two methods, or controls the fire indicator DP to display it. Can do.

(1) Polling The fire receiver FA transmits a status information request command to the fire display DP in order to collect the status of the fire display DP. On the other hand, the fire display device DP reports the state information to the fire receiver FA in response to the state information request command.

(2) Transfer control command When the fire receiver FA receives state information such as a fire from the terminal device, the fire receiver FA transmits a transfer control command to the fire display DP. The fire display device DP that has received the transfer control command displays according to the transfer control command and notifies a fire or the like.

(Operation of fire alarm equipment)
An example of the operation of the fire alarm facility will be described.
First, photoelectric analog sensors AD1-9 connected as terminal devices detect smoke, thermal analog sensors AD10-15 detect heat, or addressable transmitters AD16-18 detect push button on. Then, the information is transmitted as status information to the fire receiver FA via the signal line SG.

  The fire receiver FA collects state information transmitted from the photoelectric analog detectors AD1 to 9, the thermal analog detectors AD10 to 15 and the addressable transmitters AD16 to 18, and fire information is included in the collected state information. When (detection information exceeding a predetermined threshold or button-on detection information) is included, a control signal is transmitted to the district acoustic repeaters AD19 to AD24 to cause the district bell B to ring. Then, a transmission control signal is transmitted to the fire indicator DP to display the location of the fire.

  Here, the operation of the fire alarm system will be described in more detail by taking as an example the case where the photoelectric analog sensor AD2 detects a fire.

  The photoelectric analog sensor AD2 reports the status information at a timing corresponding to the address 2 that is its own address set in the terminal device storage unit 18, for the point polling of the fire receiver FA. When the fire receiver FA confirms the collected state information and detects that the photoelectric analog sensor AD2 exceeds a predetermined threshold value, it determines that a fire has occurred at the address 2. In order to notify the fire, the fire receiver FA receives fire data from the 1st and 1st floor, 1st district, which is the district name data corresponding to the address 2, and the message data arbitrarily set to display the district name in an easy-to-understand manner. The information is read from the machine storage unit 13, and the address, district name, and message of the terminal device where the fire has occurred are displayed on the fire receiver display operation unit 12.

  In addition to notifying the fire by display, the fire indicator FA reads the address of the district acoustic repeater installed in the same area as the address 2 from the fire receiver storage unit 13, and sends it to the district acoustic repeater AD19. Send a control command to ring the district bell by selecting and ring the district bell. When the address of the other district acoustic repeater other than the district acoustic repeater AD19 is set in the fire receiver storage unit 13 for the purpose of notifying the fire to the upper and lower floors, A control command is also sent to the district sound repeater by selecting.

  In addition, the fire receiver FA sends a transfer control signal from the fire indicator transceiver 15 to the fire indicator DP in order to notify the fire at the fire indicator DP at the same time as the fire receiver FA. The transfer control signal includes address 2 which is address information where the fire is occurring, one building, first floor, first district and message data which are district name data.

  When the fire display device DP receives the transmission control signal by the fire display device transmitting / receiving unit 23, the fire display device display operation unit 21 displays the district name “1 building 1st floor 1 district” and the terminal device as shown in FIG. "Photoelectric analog sensor" and a message "XXX restaurant" are displayed to notify the fire.

  As described above, the user can recognize the fire occurrence location with the fire receiver FA, and also can recognize the fire occurrence location with the fire indicator DP.

  Next, FIG. 4 shows a notification of failure in the fire display device display operation unit 21 of the fire display device DP when a failure occurs in the photoelectric analog sensor AD2. The method for notifying the fire indicator DP of the failure is almost the same as the method for notifying the fire described above.

  The fire receiver FA confirms the status information of the terminal device collected by point polling. When the photoelectric analog detector AD2 detects failure information, the fire receiver FA sends the district name data and message data corresponding to the address 2 to the fire receiver. Reading from the storage unit 13 and displaying the failure of the photoelectric analog sensor AD2 on the fire receiver display / operation unit 12 and transmitting a transfer control signal including address information, district name data and message data to the fire display DP .

  When the fire display device DP receives the transfer control signal transmitted from the fire receiver FA, the fire display device DP displays the district name, the type of terminal device, and a message to notify the failure of the photoelectric analog sensor AD2. The user who finds out the notification of the failure contacts the maintenance company to have the failure repaired.

  Here, looking at the failure indication displayed on the fire indicator DP, the name of the district where the failure has occurred can be seen from the “1 building, 1st floor, 1 district” which is easy to understand for the user. When a person identifies a malfunctioning terminal device, the photoelectric analog sensor AD1 and the photoelectric analog sensor AD2 are installed as in the example of FIG. 1, and therefore, the same type is installed in the same area. Therefore, it is impossible to determine which photoelectric analog sensor is faulty.

  Moreover, even if only one photoelectric analog sensor is installed in the same area, the building blueprint describing where the terminal device is installed is, for example, FIG. As shown, the photoelectric analog sensor AD2 is indicated by an address instead of a district name. In addition to the fact that the same district name can be set for a plurality of terminal devices, for example, as shown in FIG. 5B, when the tenant is switched and the section is changed, the district name of the photoelectric analog sensor AD2 is changed. In contrast to the possibility of change, the fire receiver FA manages the terminal device based on an address that is a unique number that does not overlap, so the address set in the terminal device is changed. Because there is no.

  Accordingly, when the maintenance worker repairs the failure, the display changeover switch 24 provided in the fire indicator display operation unit 21 of the fire indicator DP is used to check the address of the terminal device in which the failure has occurred. To operate. When the display changeover switch 24 is operated, the fire indicator DP displays the name of the area of the faulty terminal device from FIG. 4 according to the address data transmitted from the fire receiver FA as shown in FIG. Switch to display.

  As a result, the maintenance worker can know the address of the terminal device in which the failure has occurred in the fire indicator DP, and knows the installation location of the failed terminal device from the equipment diagram of FIG. Equipment can be repaired quickly.

  Furthermore, when the display changeover switch 24 is operated again, the fire indicator DP switches the display from the display of FIG. 6 to display both the district name and the address as shown in FIG. In this way, displaying both the district name and the address is convenient for the user and the maintenance worker to go to the place where the failure has occurred together and identify the terminal device that has failed.

  In addition, the fire indicator DP displays the district name (Fig. 4) after a certain period of time has elapsed since switching to the address display (Fig. 6) or the district name display and the address display (Fig. 7). A function to return is provided, and even if you forget to switch to the display with the district name after the repair of the failure is completed, the display automatically returns to the display with the district name.

  In addition, although the display switching of the fire indicator DP in the case of a failure notification has been described, by operating the display changeover switch 24 also in the case of a fire notification, the address display or the district name and address display is similarly performed. It is also possible to switch to.

  As described above, since the fire display device has a display switching means for displaying either or both of the district name data and the address data, the fire display device uses the district data (building) during normal use. Floor area), the user can easily determine the location of the fire, etc., and during maintenance, the address data is displayed on the fire indicator, so maintenance workers can perform maintenance at locations other than the fire receiver. The installation location of the terminal device to be performed can be easily identified.

  When the user and the maintenance worker confirm the terminal device together, the user and the maintenance worker can easily determine the installation location of the terminal device by displaying both.

  In addition, since the district name data and address data are sent from the fire receiver to the fire indicator, there is no need to set the district name data in the fire indicator storage section of the fire indicator, so the partition (district) can be changed. When changing the district name data, you only need to change the fire receiver data.

  In addition, even if the maintenance worker forgets to return the display, the fire indicator automatically returns to the district name data display after a predetermined time has elapsed, so that the user is not confused.

Embodiment 2
In the first embodiment described above, an example is shown in which the fire receiver transmits the district name data, address data, and message data of the terminal device in which a fire has occurred or has failed to the fire display device. In the second embodiment, an example in which only the address data of a terminal device in which a fire has occurred or failed is transmitted from the fire receiver to the fire display device will be described, focusing on the case where a photoelectric analog sensor AD2 failure has occurred. In the second embodiment, differences from the first embodiment will be mainly described, and the same or corresponding components as those in the first embodiment are denoted by the same reference numerals.

  In addition to the fact that the fire indicator storage unit of the first embodiment stores the program for operating the fire indicator control unit, the fire indicator storage unit of the fire indicator of the present embodiment 2 Stores district name data and message data indicating in which district the terminal device is installed.

  The fire receiver FA confirms the status information of the terminal device collected by point polling. When the photoelectric analog detector AD2 detects failure information, the fire receiver FA sends the district name data and message data corresponding to the address 2 to the fire receiver. The information is read from the storage unit 13, the failure of the photoelectric analog sensor AD <b> 2 is displayed on the fire receiver display / operation unit 12, and a transmission control signal including address data is transmitted to the fire display unit DP.

  When the fire indicator DP receives the transfer control signal transmitted from the fire receiver FA, the fire indicator DP reads out the district name data and message data corresponding to the received address data from the fire indicator storage unit 22, as shown in FIG. The district name and message are displayed on the fire indicator display / operation unit 21 to notify the failure of the photoelectric analog sensor AD2. The user who finds the failure contacts the maintenance company to have the failure repaired.

  When repairing the failure, the maintenance operator operates the display changeover switch 24 of the fire indicator DP in order to check the address of the terminal device in which the failure has occurred. When the display changeover switch 24 is operated, the fire display device DP displays the address name as shown in FIG. 6 according to the address data transmitted from the fire receiver from FIG. Switch to.

  As a result, the maintenance worker can know the address of the terminal device in which the failure has occurred in the fire indicator DP, and knows the installation location of the failed terminal device from the equipment diagram of FIG. Equipment can be repaired quickly.

  As described above, since the fire indicator has a display switching means for displaying either or both of the district name data and the address data, the district data ( The building floor area) is displayed, so the user can easily identify the location of the fire, etc., and during maintenance, the address data is displayed on the fire indicator, so maintenance workers can also perform maintenance at locations other than the fire receiver. It is possible to easily determine the installation location of the terminal device that performs the operation.

  In addition, since only the address data of the terminal device received from the fire receiver is transmitted and the district name data corresponding to the address data is read from the fire indicator storage unit by the fire indicator, the fire receiver and the fire indicator are The communication load can be reduced.
