Description

  The present invention relates to a fire receiver having a LAN connection function.

Conventionally, a fire alarm system in which fire receivers are connected to each other via a LAN shares the fire detection information of the fire receiver among the fire receivers connected via the LAN. In addition, in conventional fire alarm systems, controlled devices such as district sound and smoke control devices that are linked to fire detectors that detect fire as multiple terminal devices connected to a fire receiver. Were connected to the same fire receiver, and the linkage was performed on a receiver-by-receiver basis.

  However, in recent years, buildings have become larger and more complex, and when a plurality of fire receivers are installed to configure equipment, for example, if buildings are divided into buildings, fire monitoring is performed in each building. In many cases, conventional fire alarm systems share fire detection information with all fire receivers connected to the LAN. As a result, there was a problem that the other building where no fire had occurred could be inadvertently confused.

  In addition, when a building is enlarged, it may be connected to different fire receivers, such as a smoke outlet, a smoke exhaust fan, and a series of fire doors. Since the controlled devices are linked in units of fire receivers, there is a problem in that the controlled devices cannot be linked to fire detectors between different fire receivers.

  The present invention has been made to solve such problems, and can share information among a plurality of fire receivers connected by a LAN for each group, and different fire receivers. It is an object to provide a fire receiver capable of interlocking a controlled device to fire detectors between the two.

In addition, the fire receiver according to the present invention is a fire receiver in which a fire detector and a plurality of controlled devices that are controlled in conjunction with the fire detector are connected to each other. LAN connection interface, zone information set for each of the fire detector and its own controlled device, and a common zone set for linking with other fire receiver controlled devices Based on the zone information stored in the storage means, the controlled device linked to the same zone is activated and the common zone information when there is a notification from the storage means storing the information and the fire detector means for sending on the LAN and on the basis of the common zone information transmitted from other fire receivers via said LAN, to start the self-controlled devices that are set to the same common zone It is intended and a stage.

  As described above, according to the present invention, information on the interlocking relationship between the fire detector and the controlled device and the interlocking relationship between the fire detector and the controlled device of the other fire receiver is stored in the storage means, When there is a report from the sensor, based on the information stored in the storage means, the start information of the controlled device to be interlocked is output, and the start information to the controlled device of other fire receivers is displayed on the LAN. When the activation information sent from other fire receivers via LAN is received, the controlled device specified by the activation information is activated, so the fire between different fire receivers This has the effect that the controlled device can be linked to the sensor alert.

  First, an outline of the present invention will be described. In the present invention, a plurality of fire receivers that monitor and control a plurality of terminal devices (fire detectors, controlled devices such as district sound / smoke-proof devices) are connected and installed via a LAN (local area network). In the fire alarm system, each fire receiver on the same LAN is assigned a group number so that each fire receiver operates so as to share only information within the same group.

  Furthermore, it is possible to set a specific special group as the group number, and the fire receiver to which the special group is assigned captures all the information of each fire receiver connected to the same LAN regardless of the group number. Yes.

  As a result, the building becomes larger and more complex, and multiple fire receivers are installed to configure the equipment so that even if the building is divided into buildings, each fire can be distinguished from one building to another. By assigning a group number to the receiver, it is possible to easily classify. The same thing can be done even if there is an owner by dividing one building, and information can be shared within each stake.

  Even in buildings that are divided into buildings, there are many cases where a fire prevention center is provided to monitor fire information collectively. The fire information for each building is not required in each building, but all fire information needs to be collected in the disaster prevention center. For the function of only sharing fire information within the group number, a fire receiver is installed in the disaster prevention center. In that case, a specific special group is set up to enable centralized monitoring of the entire building.

  In addition, the present invention is installed by connecting a plurality of fire receivers that monitor and control a plurality of terminal devices (controlled devices such as fire detectors and district sound / smoke prevention devices) via a LAN (local area network). In the fire alarm system, when the fire detector is triggered, the controlled device in the zone within the same fire receiver that is set to the fire receiver is activated, and at the same time, the common fire alarm is set to the fire detector that triggered the fire. Flow zone information on the LAN so that other fire receivers recognize the common zone as activation information from the information on the LAN and activate the controlled device set in its own common zone. Yes.

  As a result, even if the building is enlarged and connected to different fire receivers, such as a smoke outlet, smoke exhaust fan, and a series of fire doors, it is possible to set up the controlled device that is linked when the fire detector is triggered. Set a common zone number for controlling equipment connected to a different fire receiver than the corresponding fire receiver, and the relevant fire receiver transmits the common zone number as information on the LAN and sends it to the LAN. All the connected fire receivers receive the common zone number as information, and it becomes possible to activate the controlled device in which the common zone number is set in each fire receiver. At this time, even if there are a large number of devices that are activated via the LAN, it is simple because only the common zone number is sent as information on the LAN.

  Next, details of this embodiment will be described. FIG. 1 is a block diagram showing a configuration of a fire receiver according to an embodiment of the present invention. In the figure, 1 is a fire receiver body, 10 is a terminal interface to which a plurality of terminal devices such as fire detectors and controlled devices are connected via a signal line L, and 11 is a LAN for connecting to other fire receivers. Interface, 12 is a display unit, 13 is an operation unit, 14 is a storage unit that stores various setting information including a receiver number, a group number, and a linkage table described later, and 15 is a control unit that controls the entire fire receiver. . AD indicates the address (AD1, AD2,...) Set in each terminal. In FIG. 1, AD1, AD2, AD15, and AD16 represent fire detectors, and AD3 and AD17 are districts. The sound device, AD45, is a smoke prevention device, and the district sound device and the smoke prevention device are controlled devices.

  In FIG. 1, seven terminal devices are connected to the fire receiver 1, but up to 510 terminal devices, for example, can be connected to the fire receiver 1. The terminal devices are grouped according to zones. For example, the terminal devices with addresses AD1, AD2, and AD3 are zone 1 (Z1), the terminal devices with AD15, AD16, and AD17 are zone 7 (Z7), and AD45. The terminal device is set to zone 12 (Z12), and the terminal device in each zone is linked.

  Also, Z12 is set as a zone to be linked to the terminal device of AD1, and the terminal device of Z12 is activated when the fire detector of AD1 is triggered. For example, when the fire detector of AD1 is triggered, Z1 and Z12 are set as AD1 interlocking data, so the fire receiver 1 controls the activation of the terminal device of Z1 and the terminal device of Z12, The AD3 area sound device and the AD45 smoke prevention device are activated, and the district ringing and smoke prevention control are performed.

  In addition, each terminal device can set a common zone (IP zone) as a zone for linking with a terminal device connected to another fire receiver. For example, the terminal device of Z12 AD45 is called IP1. A zone is set, and a zone called IP2 is set in the terminal devices of AD15, AD16, and AD17 of Z7.

  The settings of these zones are stored in the storage unit 14 as data of an interlocking table as shown in FIG. This linkage table is set by being input from the operation unit 13 or transferred from an external personal computer or the like.

  And the fire receiver as shown in FIG. 1 is connected by LAN as shown in FIG. 3, and the fire alarm system is comprised. In FIG. 3, the fire receiver of FIG. 1 shows the fire receiver of # 5, and the fire receivers of # 1 to # 4 are configured as shown in FIG. 1 except for the terminal device address and various zone settings. It is the same as the receiver. The LAN is, for example, a LAN using the RS485 standard. As shown in FIG. 3, the fire receivers 1 may be connected in a loop as shown in FIG. Just connect.

  In addition, the fire receivers 1 connected to the LAN can be grouped by setting a group number. The fire receivers 1 and # 3 have GR1 (group 1) as # 4, The fire receiver # 5 is set to GR2 (group 2). Furthermore, GR0 (group 0) as a special group is set for the fire receiver # 1. Note that # 1 to # 5 of each fire receiver 1 are receiver numbers for distinguishing each other on the LAN.

  Next, the operation of this embodiment will be described. First, for example, when the fire detector of AD1 of the # 5 fire receiver 1 issues a report, the # 5 fire receiver 1 outputs the information to the LAN together with the group number. And each other fire receiver is based on the information from the # 5 fire receiver 1 on the LAN, the fire receiver of the same group as the # 5 fire receiver 1, here, # 2 of GR2 For example, “# 5-AD1 Fire” is displayed on the display unit 12 of the fire receiver.

  At this time, the fire receivers 1 and # 3 are groups of GR1 and are different from the fire receiver 1 of # 5. Therefore, in the fire receivers 1 and # 3, the display unit 12 Is not displayed. The # 1 fire receiver 1 in which GR0 is set operates as a special fire receiver that accepts all groups of information to be received without distinction, and the # 1 fire receiver 1 is also “# 5-AD1 Fire”. Is displayed.

  In addition, each fire receiver 1 outputs the fire information together with the group number to the LAN, and determines whether or not the display is necessary from the group number of the received information, but uses the receiver number instead of the group number. Also good. In other words, instead of the group number, each fire receiver 1 is set with the receiver number of the fire receiver to be handled in the same group, and fire information with the receiver number is stored in the LAN (the receiver number is in the information). Each fire receiver 1 may output and display the receiver number if it is set by determining the receiver number from the received information. At this time, each fire receiver 1 does not need to use a group number when outputting information to the LAN. The necessity of display can be distinguished using the necessary receiver number as fire information.

  Each terminal device is controlled to operate in conjunction with an interlocking table such as that shown in FIG. 2 stored in the storage unit 14 in the connected fire receiver 1. The table recognizes the group of each terminal device and performs interlocking control between the terminal devices.

  For example, when the fire detector of AD1 of # 5 fire receiver 1 is in alarm, as shown in FIG. 2, Z1 and Z12 are set as AD1 interlocking data. The terminal device of Z1 and the terminal device of Z12 are activated and controlled via the signal line L, the AD3 area sound device and the AD45 smoke prevention device are activated, and the district ringing and smoke prevention control are performed. As shown in FIG. 2, since a zone is set for each terminal device address, the area of the device to issue and the area of the activated device do not need to be the same. Further, zones other than the Z1,... IP zones are set for each fire receiver 1, and there is no function for linking to different receivers.

  In addition, in the setting of the linkage table of each fire receiver 1, linkage information between the receivers is set as an IP zone. In FIG. 2, the fire detector of AD1 of the fire receiver # 5 has , IP1 is set, IP1 is set for the smoke-proof device of AD45, and IP2 is set similarly in the range of Z7.

  For example, when the smoke evacuation device is a fire door, the fire doors are activated all at once, so as shown in FIG. 3, each fire door # 2-AD95, # 3-AD35, # 4-AD45, # 5 -When IP1 is set in AD45 and the fire detector of AD1 of # 5 fire receiver 1 issues a warning, # 5 fire receiver 1 Then, activation control of the terminal device of Z1 and the terminal device of Z12 is performed via the signal line L, and the AD3 area sound device and the anti-smoke device of AD45 are activated, and activation information of IP1 is transmitted on the LAN.

  When the fire receiver 1 connected to the LAN receives the activation information of IP1, each fire receiver controls the IP1 device in an interlocked manner. Therefore, IP1 is set in the # 2 fire receiver 1. Similarly, the AD95 smoke evacuation device is activated. Similarly, the # 3 fire receiver 1 activates the AD35 smoke evacuation device to which IP1 is set, and the # 4 fire receiver 1 is set to IP1. Activate the AD45 smoke evacuation device.

  In addition, it is necessary to recover after the fire is extinguished for the smoke-proof device with IP1 activated in this way, but the range of GR2 is determined by the recovery operation not shown in detail for the fire receiver 1 of # 5. Each terminal device is restored at once. Based on this restoration operation, information on restoration of IP1 is sent to the LAN. And each fire receiver 1 responds similarly to the case of starting, and the activated smoke prevention apparatus can each be restored.

  In addition, when recovery points are taken into account, even in a fire receiver in a different group, if activation control is performed using the IP zone, that fact can be displayed. In that case, the system status of each fire receiver Since the smoke-proof device is activated in terms of display, it is preferable to display the factor and activation contents on the display unit because the state and the display coincide. And by displaying on the display part of a fire receiver, even if recovery operation is not performed in the fire receiver used as a factor, it is possible to perform recovery operation of the smoke-proof device individually.

  Such interlocking by the zone setting between the fire receivers is used not only for smoke prevention equipment but also for the function of the district sound. When it is desired to make the ringing of the fire receiver 1 of Z7 at Z7, IP2 is set to the fire receiver 1 of # 5 in the same manner as Z7. The fire receiver 1 outputs IP2 activation information on the LAN, and the # 5 fire receiver 1 controls activation of the set terminal device of the AD 17 based on the IP2 activation information.

  As shown in FIG. 2, as with the zones of Z1,..., The IP zone is set for the address of each terminal device, so the zone of each fire receiver 1 and the IP zone must be the same. There is no. The IP zone for linking between fire receivers can be set for each fire receiver, and the IP zone output side and input side can be set individually, so management is possible even when changes are made. Easy.

  In addition, you may set the information of the zone regarding the interlock | linkage set in each fire receiver 1 with each terminal apparatus with an IP zone. That is, for example, taking the fire door as described above as an example, Z1 and IP1 are set as zones in the fire detector of AD1 of the fire receiver # 5 and the fire door of AD45, and the fire detector of AD1 The fire receiver 1 of # 5 outputs Z12 via the signal line L by the notification, determines that the AD45 fire door itself is in its own zone, and starts up, and outputs IP1 to the LAN. When each fire receiver 1 receives IP1 from the LAN, it outputs IP1 to each signal line L, and the IP1 is set as the terminal device of each part. Each fire door starts upon receiving IP1.

  At this time, in the above embodiment, there is an advantage that data for interlocking is collectively set in the storage unit 14, but it is necessary to set information regarding the interlocking in each fire receiver 1 by this modification. In addition, the capacity of the storage unit 14 is reduced, and the control unit 15 may save time and effort for addressing from the IP zone.

  In this embodiment, in the fire alarm system in which a plurality of fire receivers are connected by a LAN, each fire receiver is divided into groups, and fire information is shared only between the groups. Even when multiple fire receivers are used in a large building, it is possible to share fire information that does not cause confusion, and fire receivers set as a special group are all fire receivers. Since the fire information from is shared, centralized monitoring can be performed easily.

  In addition, the zone setting in the fire receiver for the address of the terminal device and the common IP zone between different fire receivers are stored in each fire receiver as a linked table, and based on the information in the linked table, In response to the fire detector's notification, it performs the linked operation process in the zone within the fire receiver, and sends the activation information of the IP zone on the LAN, and the same IP zone connected to other fire receivers. Since the terminal device is operated, it becomes possible to link the controlled device with respect to the fire detector reporting between different fire receivers.

  In this embodiment, as shown in FIG. 2, seven zone settings can be set for the address of each terminal device, but seven or more zone settings may be set. . In this embodiment, the LAN is configured by a LAN using the RS485 standard. However, each fire receiver can receive information from other fire receivers, and is the same for all other fire receivers. Any LAN that can transmit information may be used.

  Further, as another embodiment different from the above, different special groups will be described. Assuming that the receiver number and group number of each fire receiver 1 connected to the LAN are the same, GR0 is set in the above embodiment. Although it was a special group that accepts all groups of information received via the LAN as a special group, in other embodiments, conversely, all groups received information received via the LAN. Special group.

  The operation when the GR0 is set as another special group will be described. In FIG. 3, for example, when the fire detector of the AD1 of the fire receiver 1 of # 1 is notified, the fire receiver 1 of # 1 The information is output to the LAN together with GR0. The other fire receivers display, for example, “# 1-AD1 Fire” on the display units 12 of all the fire receivers 1 based on the information from the # 1 fire receiver 1 on the LAN. To do. At this time, the fire receivers # 2 to # 5 have different groups, and display is not performed if they are normal groups. However, if it is a special group, it is displayed on the display unit 12 as in the same group.

  There is also a demand for such operation to share the fire information in the main part of equipment such as electric equipment and elevator equipment, for example, even in buildings that are divided into buildings. In that case, it is possible to set a special group for the fire receivers that monitor a specific range, and to display the fire information output from the fire receivers of the special group via the LAN on all fire receivers. It is possible. It should be noted that the special group number 0 in the other embodiments can be mixed and distinguished from the special group in the one embodiment by using a different number such as 100.
