  Hereinafter, embodiments of a fire receiver according to the present invention will be described with reference to the drawings. FIG. 1 is a system configuration diagram showing a preferred embodiment of a fire receiver according to the present invention. The fire receiver FA includes a plurality of terminal devices such as a fire detector connected via a signal line SG. The fire receiver FA and each terminal device are, for example, a high level voltage (V1H) and a low level. Communication is performed by a pulse signal of a combination of level voltage (V1L). Each terminal device is assigned a unique address AD, and the fire receiver FA can identify each terminal device by this address AD.

  Examples of terminal equipment connected to the fire receiver FA include a photoelectric analog sensor SE11, a thermal analog sensor SE12, an addressable transmitter SE13, and the like. The photoelectric analog sensor SE11 is a kind of smoke sensor, and transmits the detected smoke analog value to the fire receiver FA. The thermal analog sensor SE12 is a kind of thermal sensor, and transmits an analog value of the detected ambient temperature to the fire receiver FA. The addressable transmitter SE13 is a so-called fire transmitter, and includes a push button that is manually operated by a person who finds the fire, and transmits a fire signal to the fire receiver FA when the push button is turned on.

  In addition, a controlled device is connected to the signal line SG via various repeaters that are terminal devices. In FIG. 1, for example, a district bell relay B11 is connected to the signal line SG, and four district bells B111 to B114 are connected to the district bell relay B11. And each district bell B111-B114 outputs the sound for alerting | reporting a fire according to the control signal from fire receiver FA. The signal line SG is connected to a smoke prevention control repeater D11. The smoke prevention control repeater D11 is connected to a fire prevention door D111 as a smoke prevention device, a smoke exhauster D112, a shutter D113, and A sagging wall D114 is connected. The terminal devices connected to these signal lines SG communicate with the fire receiver FA via the signal lines SG and are supplied with power via the signal lines SG.

The fire receiver FA collects terminal device status information or controls the terminal device and the like by the following three methods of point polling, selecting, and system polling with each terminal device.
(1-1) Point polling The fire receiver FA transmits a status information request command to a terminal device by collecting several units as one 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 AD in response to the status information request command, and reports the status information to the fire receiver FA. The fire receiver FA repeatedly communicates with such a group and collects status information of all terminal devices.

(1-2) Selecting The fire receiver FA designates an address AD corresponding to a desired terminal device and transmits a predetermined control command to control the terminal device or state information to the desired terminal device. Etc., and collects status information from individual terminal devices. In response to the control command, the terminal device designated with the address AD reports the control result to the fire receiver FA or reports the requested status information.

(1-3) System Polling The fire receiver FA transmits a common control command to all terminal devices and controls each terminal device. As control commands by system polling, for example, a fire recovery command (command to restore a sensor or a relay that outputs a fire signal to a normal monitoring state), a district sound stop command (a ring bell relay B11 that is ringing) Command to stop).

(2) Collection of information on occurrence of abnormality The fire receiver FA stores the storage unit 3 when the state information collected by point polling from a terminal device such as the photoelectric analog sensor SE11 includes fire information. The control device is operated by transmitting a control signal by selecting to the smoke prevention control repeater D11 corresponding to the terminal device that transmitted the fire information in accordance with the database stored in. In addition, when a status information request command is transmitted by point polling to a terminal device registered in the database stored in the storage unit 3 of the fire receiver FA, a terminal device that does not respond to the status information request command If it exists, a message indicating no response is displayed on the display operation unit 2 as will be described later.

  FIG. 2 is a functional block diagram showing an example of the fire receiver FA of FIG. The fire receiver FA includes a display operation unit 2, a storage unit 3, a data extraction unit 4, and a display control unit 5. The operation control unit 1 controls the operation of the fire receiver FA, and performs the above-described various polling to each terminal device via the transmission / reception unit 7, collects the status of each terminal device, and performs tests, etc. The various operations are performed. The operation control unit 1 has a function of storing the state of each terminal device collected by various polling in the storage unit 3.

  Note that a plurality of (for example, 1 to 12 systems) transmission / reception units 7 are provided in the fire receiver FA, and a plurality of terminal devices are connected to each transmission / reception unit 7 via signal lines SG. Further, the operation control unit 1 is connected to another fire receiver FA via the network connection unit 6, and data can be transmitted to and from the other fire receiver FA via the network NW. Furthermore, the fire receiver FA is connected with a plurality of display devices 10 including LED display devices, LCD display devices, and the like for notifying a fire or the like.

  The display operation unit 2 includes, for example, a touch panel. The display operation unit 2 has a function as a display unit that displays various types of information, and also functions as an operation unit that allows an operator to select a predetermined switch (command button) by touching the screen. Have. Accordingly, a predetermined screen is displayed on the display operation unit 2 and a predetermined selection signal is output to the operation control unit 1 when the operator touches the panel. The display of the display operation unit 2 is controlled by the display control unit 5.

  The storage unit 3 stores a terminal database DB that stores various data related to terminal devices. FIG. 3 is a diagram illustrating an example of the data structure of the terminal database DB stored in the storage unit 3. The terminal database DB can be registered / updated by an external database creation device 15. The terminal database DB of FIG. 3 stores the address AD of each terminal device connected to the fire receiver FA and the terminal device type KI (hereinafter also referred to as type KI) in association with each other. More specifically, the terminal database stores “system”, “address number AD”, “terminal device type KI”, “serial number”, “type of controlled device”, and “installation location SP”.

  The “system” indicates which of the plurality of transmission / reception units 7 is a terminal device connected to the transmission / reception unit 7. The “address AD” is a number assigned to each terminal device so that the fire receiver FA can identify which terminal device is used when the transmitter / receiver 7 communicates with each terminal device via the signal line SG. It is. The “terminal device type KI” means the type of each terminal device that can directly communicate with the fire receiver FA via the signal line SG. In FIG. 3, the terminal device type KI is illustrated as being stored with an actual name, but the type code corresponding to each type is assigned and the terminal device is classified and managed by the assigned type code. Also good.

  "Serial number" corresponds to the smoke-proof device (each control line to which the device is connected) in order to specify which of a plurality of controlled devices connected to one repeater is controlled. It is a number assigned. For example, serial numbers 1 to 4 are assigned to each of the fire door D111, the smoke evacuator D112, the shutter D113, and the leaning wall D114 connected to the smoke evacuation control repeater D11. The “type of controlled device” corresponds to a type condition for specifying the type of a plurality of controlled devices, and means a type of fire door, smoke exhaust, shutter, leaning wall, etc., for example. The “installation location SP” is information indicating a location where the terminal device is installed, and indicates, for example, “first floor A”, “first floor B”, “first floor corridor”, and the like.

  The data extraction unit 4 in FIG. 2 displays the terminal device of the type KI related to the function of the selected fire receiver FA when the function is selected from the plurality of functions of the fire receiver FA. Is extracted from The display control unit 5 displays the address AD and type KI extracted by the data extraction unit 4 as a terminal device control switch 31 described later. Hereinafter, the operations of the data extraction unit 4 and the display control unit 5 will be described with reference to the screens displayed on the display operation unit 2 shown in FIGS.

  First, the display control unit 5 displays a function selection window 20 for selecting the function of the fire receiver FA on the display operation unit 2. FIG. 4 is a schematic diagram showing an example of a function selection window displayed on the display operation unit 2 of FIG. The function selection window 20 displays a list of a plurality of function selection switches 21A to 21H, and the operator can select any one of the function selection switches 21A to 21H. Examples of the function of the fire receiver FA include functions such as a fire test and terminal control. The "Fire Test" function sends a fire control command from the fire receiver FA to a fire detector such as the photoelectric analog sensor SE11 or the thermal analog sensor SE12, and the fire detector detects the fire normally. This is a function to test whether it is possible. Further, the “terminal control” function is a function for operating a connected controlled device by transmitting a control command from the fire receiver FA to the smoke prevention repeater D11. If the “end” switch displayed on the screen is operated, the display of the function selection window 20 can be ended and the screen can be returned to the upper layer screen.

  For example, when one function selection switch 21A of the display operation unit 2 is selected by the operator, the data extraction unit 4 extracts terminal devices matching the type KI related to the selected function from the terminal database DB. . At this time, the function of the fire receiver FA as shown in the function selection switches 21A to 21H and the type KI of the terminal device related to the function are stored in the data extraction unit 4 in association with each other. When the predetermined function selection switch 21A is selected, the data extraction unit 4 extracts the address AD, the type KI, and the installation location SP of the terminal device that matches the type KI related to the selected function from the terminal database DB. It is like that. Then, the display control unit 5 switches the display of the display operation unit 2 from the function selection window 20 to the terminal device list window 30, and displays the terminal device address AD and the type KI extracted by the data extraction unit 4. The device control switch 31 is displayed as a list on the display operation unit 2.

  5A and 5B are schematic diagrams illustrating an example of the terminal device list window 30 displayed on the display operation unit 2. 5A and 5B exemplify the case where the system is indicated in addition to the address AD in the format of “system-address number”. For example, the number “01-001” is written on the terminal device having the address number 001 of the system 1.

  FIG. 5A shows a terminal device list window 30 when the “fire test” switch 21A is selected in the function selection window 20 of FIG. The terminal device list window 30 of FIG. 5A displays a list of terminal device control switches 31 of terminal devices related to the “fire test” switch 21A connected to a predetermined system (for example, the initial system 1). Here, the display control unit 5 displays a list of a plurality of terminal devices extracted by the data extraction unit 4 in the order of addresses AD. Normally, terminal devices with addresses AD close to each other tend to be installed in close locations, so that by arranging in order of address AD, the operator can install terminal devices installed in close locations based on the terminal device list window 30. Can be operated continuously. When performing the fire test, the terminal device control switch 31 of the address AD where the fire test is to be performed is operated from among the terminal device control switches 31 displayed in a list. Then, the fire receiver FA transmits a fire test control command to the fire detector at the operated address AD, and causes the fire detector to perform the fire test.

  A plurality of system selection switches 32 for switching systems are arranged in the right area of the terminal device list window 30. And when an operator selects the system | strain selection switch 32, among the several terminal devices connected to a different system | strain, the terminal device control switch 31 regarding the terminal device corresponding to the selected system | strain will be displayed as a list. Become. Further, a “next switch” and a “previous switch” for scrolling the page are provided at the lower right of the terminal device list window 30. When the next switch is selected, the terminal device control switch 31 having a larger address AD number is provided. Will be listed. The page may be scrolled by another method such as a scroll bar.

  The display control unit 5 in FIG. 2 has a function of causing the display operation unit 2 to display the terminal device control switch 31 by changing the display mode according to the state (status) of each terminal device. Specifically, the display control unit 5 is color-coded according to the state and is displayed on the display operation unit 2. For example, when the display control unit 5 is activated and controlled, yellow (in FIGS. 5A and 5B, The terminal device control switch 31 is colored blue (represented by a lattice pattern in FIGS. 5A and 5B) when an abnormality that cannot be blocked or controlled has occurred.

  In FIG. 5A, the terminal device control switch 31 that is not colored is indicating the address of a fire detector that is operating normally but has not been subjected to a fire test. The “01-002 thermal analog sensor” marked in yellow indicates that the terminal device has been fire tested. This indicates that an abnormality that cannot be controlled has occurred in the terminal device with the address AD of “01-016” that is marked in blue.

  Further, in FIG. 5B, “01-050-4 dripping wall” indicated by yellow indicates that the controlled device has already been controlled. On the other hand, the terminal devices with addresses AD of “01-054-1”, “01-054-2”, “01-054-3”, and “01-054-4” that are marked in blue can be controlled. This indicates that an error that cannot be made has occurred. When there is an address AD to which no abnormal terminal device is connected, the display control unit 5 may not display the terminal device control switch 31 of the address AD. Only the “address number” may be written or the terminal device control switch 31 that is all blank may be displayed. Alternatively, the terminal device control switch 31 of the address AD may not be displayed or the blank terminal device control switch 31 may be displayed.

Thus, by coloring the terminal device control switch 31 displayed in a list and displaying the status, the operator can grasp the status of a plurality of terminal devices at a glance, thereby improving work efficiency. it can. In addition, by displaying the terminal device in which the abnormality has occurred so that the display state of the terminal device control switch 31 is different, the operator does not attempt to access the terminal device that cannot be controlled due to the abnormality. Since it is possible to specify that an abnormality has occurred and the terminal device in which the abnormality has occurred, it is possible to improve work efficiency. Furthermore, since the terminal device control switch 31 whose operation has been confirmed and the terminal device control switch 31 before the operation confirmation are displayed in different modes, the controlled terminal device can be easily identified. Can also be prevented from operating the same terminal.
In addition, the terminal AD control switch 31 of the address AD in which an abnormality that cannot be controlled has occurred or the controlled address AD may be displayed or not displayed. When the display operation unit 2 is set not to display the terminal device control switch 31 of the controlled address AD, the display control unit 5 selects a controlled terminal device among the terminal devices extracted by the data extraction unit 4. The excluded terminal device control switch 31 is displayed in a list on the display operation unit 2.

  5A and 5B, the display control unit 5 illustrates the case where the address AD and the type KI are displayed on the terminal device control switch 31, but as shown in FIG. You may display on the terminal device control switch 31 with AD and classification KI. As a result, it is easier to understand where the terminal device is installed than the display of only the address AD, and it is possible to instantly understand where the abnormality is occurring.

  Next, the display control method of the fire receiver FA will be described with reference to FIGS. First, the display control unit 5 displays a function selection window 20 in which a plurality of pieces of function information are arranged as function selection switches 21A to 21H on the display operation unit 2 (see FIG. 4). When the operator selects one function selection switch (for example, the fire test switch 21A), the terminal device (for example, photoelectric type) that matches the type KI associated with the function selected from the terminal database DB in the data extraction unit 4 Terminal devices related to fire (analog sensor, thermal analog sensor, addressable transmitter, etc.) are extracted from the terminal database DB. Thereafter, the terminal device control switch 31 displaying the terminal device address AD and the type KI extracted by the display control unit 5 is displayed in a list on the display operation unit 2 (see FIGS. 5A, 5B, and 6). In particular, each terminal device control switch 31 is displayed in a state colored according to the state (status).

  When a specific terminal device control switch 31 is selected by the operator, a control command is transmitted from the fire receiver FA to the terminal device at the address AD of the terminal device control switch 31, and the terminal device that has received the control command is Operate.

  According to the above-described embodiment, by displaying a list of controllable terminal devices by simply selecting each function selection switch 31, it is possible to control by a simple operation, and thus workability when performing maintenance, construction, or the like. Can be improved. In addition, since the list is displayed in the order of address AD, even if the operator does not know the exact address AD of the terminal device to be operated, the previous and next addresses AD and the type KI of the terminal device are displayed. Therefore, it is possible to easily find a terminal device to be operated and to improve operability.

  The embodiment of the present invention is not limited to the above embodiment. For example, in FIG. 2, a case where a display operation unit (touch panel) 2 in which a display unit and an operation unit are integrally provided is illustrated, but the display unit and the operation unit are provided separately. Also good. For example, the display unit consists of a liquid crystal panel, etc., and the operation unit consists of a mouse, mouse pad, keyboard, etc., and the operator operates the operation unit while watching the display on the display unit and selects various switches. There may be.

  Moreover, in the said embodiment, although the terminal device list window 30 has illustrated about the case where the terminal device connected to the signal line SG is displayed, for example, other fire receptions connected to the display 10 or the network NW The machine FA may be displayed as a list of terminal devices. When the worker selects a specific fire receiver FA, detailed information on the fire receiver FA may be displayed.

  Further, in FIGS. 5A, 5B, and 6, the case where the background color of the terminal device control switch 31 is changed is illustrated as an example of changing the display mode. However, the characters displayed on the terminal device control switch 31 are illustrated. The color of the display may be changed, or the switch may be shaded, or the display method such as blinking may be changed.
