Description

  The present invention relates to a distributed fire alarm system, and in particular, allows a setting data register to easily rewrite setting data of a main repeater or a distributed fire receiver via a transmission line.

  A plurality of main repeaters that monitor and control a plurality of terminal devices connected via signal lines, and a plurality of main repeaters connected to the plurality of main repeaters via transmission lines, and disaster prevention between the plurality of main repeaters A distributed fire alarm system including a distributed fire receiver that transmits and receives information is known (see, for example, Patent Document 1).

  A plurality of main repeaters and distributed fire receivers as host devices are distributed in various places in order to perform fire monitoring over a wide area such as a huge building or a plurality of buildings.

  Multiple main repeaters connect to the main repeater, common setting data common to each host device, such as network data that stores the node number and node type of the host device in correspondence with each other, system data common to the system, etc. Terminal data related to a plurality of terminal devices, the individual individual setting data in the main repeater such as the terminal interlocking table, and the like in the main repeater memory, the distributed fire receiver, the common setting data, The individual setting data of all the main repeaters were stored in the receiver memory.

  In this way, since the distributed fire receiver stores the individual setting data of a plurality of main repeaters in the receiver memory, the main repeater receives the disaster prevention information such as fire information and the terminal address via the transmission line. When it is sent out, the distributed fire receiver receives the disaster prevention information and the terminal address sent from the main repeater, and receives the terminal data corresponding to the terminal address (for example, an optional message such as the setting location). Since it can be read from the machine memory and displayed on the display means together with the disaster prevention information and the terminal address, the administrator can confirm the status of the entire system in detail.

For the main repeater and the main repeater memory and receiver memory of the distributed fire receiver, for example, a memory card which is a readable / writable and nonvolatile storage medium is used.
Japanese Patent Laid-Open No. 5-217088

  When changing various setting data in a conventional distributed fire alarm system, use the setting data register to create setting data for update, store it in the setting data storage unit, and rewrite it to the attached memory card. The memory card is replaced with a memory card of a main repeater or a distributed fire receiver whose setting data is updated.

  For this reason, conventionally, in order to update the setting data, it is necessary to go to the installation site of each host device where the setting data to be updated is used, and to individually replace the memory card.

  An object of this invention is to be able to perform the update operation | work of the setting data of a main repeater or a distributed fire receiver simply.

  The present invention provides a plurality of main repeaters for monitoring and controlling a plurality of terminal devices connected via signal lines, and a plurality of main repeaters connected to the plurality of main repeaters via transmission lines. In a distributed fire alarm system comprising a distributed fire receiver that transmits and receives disaster prevention information, the distributed fire receiver includes a receiver memory that stores setting data of the distributed fire receiver, A receiver LAN interface for receiving setting data for updating the distributed fire receiver via a transmission line; a receiver control unit for rewriting and updating the setting data of the distributed fire receiver stored in the receiver memory; The plurality of main repeaters include a main repeater memory that stores setting data of the main repeater, and a main repeater LAN that receives setting data for updating the main repeater via the transmission line. interface A main relay controller that rewrites and updates the setting data of the main relay stored in the main relay memory, the receiver LAN interface or the main relay LAN interface is the distributed receiver or A setting data register for storing update setting data for the main repeater is connected, and the update setting data is sent to the transmission line.

  The distributed fire receiver and the plurality of main repeaters are all provided with connection ports for connecting the setting data register.

  The plurality of main repeaters include common setting data common to the plurality of main repeaters and distributed fire receivers, terminal data related to a plurality of terminal devices connected to the main repeaters, a terminal link table, etc. Individual setting data individually stored in the main repeater memory, and when sending the disaster prevention information via the transmission line, individual setting data related to the disaster prevention information is stored. The distributed fire receiver is provided with individual setting data sending means for giving and sending, and the common setting data is stored in the receiver memory and sent from the main repeater via the transmission line. It is characterized by comprising individual setting data acquisition and display means for receiving disaster prevention information and individual setting data and displaying them on the display means.

  In the present invention, the setting data register is connected to the receiver or the main repeater LAN interface, and the setting data for updating the main repeater or the distributed fire receiver is sent to the transmission line. The distributed fire receiver or the main repeater, which is each host device, can receive its own update setting data via the LAN and rewrite the setting data. Therefore, when updating the setting data, it is not necessary to go to the installation site of each host device where the setting data to be updated is used, and the updating work is not necessary.

  In addition, since all of the distributed fire receiver and the plurality of main repeaters are provided with a connection port for connecting the setting data register, any setting can be made by connecting a setting data register to the connection port of any host device. The setting data of the host device can be updated.

  The plurality of main repeaters include common setting data common to the plurality of main repeaters and distributed fire receivers, terminal data related to a plurality of terminal devices connected to the main repeaters, a terminal link table, etc. The main repeater stores individual individual setting data in the main repeater memory, and the distributed fire receiver stores the common setting data in the receiver memory, It was set as the structure which does not memorize | store the individual setting data of a repeater. At this time, when a plurality of main repeaters send out the disaster prevention information via the transmission line, it sends out individual setting data related to the disaster prevention information, and a distributed fire receiver By receiving the disaster prevention information and individual setting data sent from the main repeater via the transmission line, the distributed fire receiver, as before, has the individual setting data of all the main repeaters stored in the receiver memory. Even if it is the structure which is not memorize | stored, it becomes the structure which can display separately set data on a display means with disaster prevention information similarly to the past. In addition, the memory capacity of the receiver memory can be reduced as compared with the conventional case. In addition, since such an arrangement of individual setting data is used, when updating the setting data of a certain main repeater, in the conventional arrangement of individual setting data, the main repeater and the distributed fire receiver are connected to the transmission line. It is necessary to rewrite and update the individual setting data transferred through the network, but only the main relay unit needs to be rewritten and updated. Each time the individual setting data of each main relay unit is updated, it is distributed. The fire receiver does not need to update the corresponding individual setting data. Thereby, for example, the transfer time of the individual setting data through the transmission line is shortened, and adverse effects such as collision with other disaster prevention information on the transmission line can be reduced.

  The best mode for carrying out the invention is the following examples.

As an example, the main repeater LM # 5 will be described as an example, but the other main repeaters LM have the same configuration. The LAN interface 21 includes a transmission control unit 45, a transmission / reception unit 46, a first-arrival determination retransmission circuit unit 47, and four transmission / reception ports 28A to 28D. The same functions as the configuration of the corresponding LAN interface 11 are provided. Therefore, explanation is omitted.

  Note that a LAN is connected to the transmission / reception ports 28A and 28B, but the other transmission / reception ports 28C and 28D are vacant ports for LAN expansion. The empty ports 28C and 28D are used for connection to the database creation device 60.

  Next, the storage units 14 and 24 of the host devices LM and RE will be described in detail. FIG. 6 is a diagram showing the configuration of the storage unit 14 of the distributed fire receiver RE. As shown in FIG. 6A, the storage unit 14 of the fire receiver RE includes a setting data storage area 16 that uses a nonvolatile storage medium such as a flash memory and a work area 17 that uses a volatile storage medium such as a RAM. And have.

  The setting data storage area 16 includes a local node number storage area 16a for storing the local node number, a network data storage area 16b for storing the node number and node type of the host device connected to the LAN, and each host device in the system. A system data storage area 16c for storing common system data, a terminal data storage area 16d for storing terminal data of terminal equipment connected to the own apparatus via the signal line L, and a terminal data storage area 16d for connecting to the own apparatus via the signal line L A terminal interlocking table storage area 16e for storing a terminal interlocking table of the terminal device. In other words, the set data type includes its own node number, network data, system data, terminal data, and terminal link table. Here, the network data and system data are sent to a plurality of main repeaters LM and distributed fire receivers RE. It is an example of common setting data that is common, and the own node number, terminal data, and terminal link table are examples of individual setting data that are individual to the distributed fire receiver RE.

  Next, as shown in FIG. 6B, in the system data storage area 16c, for example, the property name, the district acoustic sequential ringing time, the district acoustic expansion alarm time, and the storage time automatic change function presence / absence are set. It is remembered. In the district sound sequential ringing time, the ring bell stop ringing when the fire detector S is triggered by turning on the zone bell stop switch (not shown) of the operation unit 13 is ringed again. The ringing stop release time is set and stored, and the district sound expansion warning time is set and stored as the waiting time until the transition from ringing of the floor bell of District Bell B to ringing of all floors. It is set and stored whether or not it is possible to change the setting of the accumulation time from when the fire detector S detects a fire to when it is triggered (fire confirmed) by an input operation from the operation unit 13.

  The terminal data storage area 16d corresponds to the terminal address AD of the terminal device connected to the own device via the signal line L, and as the terminal data of the terminal device, for example, a smoke detector, a heat detector, a district The type (ID) of the terminal device such as a bell, smoke prevention device, the sensitivity level (KL) that is the fire detection threshold of the fire detector S, and the time from when the fire detector S detects fire (fire confirmation) An option message (OP message) for setting and storing the storage time, the building floor number, the installation location name of the terminal device, and the like are stored.

  In the terminal link table storage area 16e, as a terminal link table of a terminal device connected to the own device via the signal line L, the terminal of the link destination terminal device corresponds to the terminal address AD of the link source terminal device. Address AD is stored. As a result, the activation-destination terminal device can be controlled to start by the operation of the linkage-source terminal device.

  FIG. 7 is a diagram showing the configuration of the storage unit 24 of the main repeater LM. As an example, the main repeater LM # 5 will be described as an example, but the other main repeaters LM have the same configuration. .

  The storage unit 24 of the # 5 main repeater LM has the same configuration as the storage unit 14 of the fire receiver RE, and as shown in FIG. 7A, a setting using a nonvolatile storage medium such as a flash memory is used. It has a data storage area 26 and a work area 27 in which a volatile storage medium such as a RAM is used. The setting data storage area 26 includes a local node number storage area 26a for storing the local node number, a network data storage area 26b for storing the node number and node type of the host device connected to the LAN, and each host in the system. A system data storage area 26c for storing system data common to devices, a terminal data storage area 26d for storing terminal data of terminal devices connected to the own device via a signal line L, and a signal line L to the own device A terminal interlocking table storage area 26e for storing a terminal interlocking table of connected terminal devices is provided.

  The own node number storage area 26a, the terminal data storage area 26d, and the terminal link table storage area 26e are different from the contents of the corresponding storage areas 16a, 16d, and 16e of the fire receiver RE, and are related to the own machine. However, the network data storage area 26b and the system data storage area 26c are the same as the contents of the corresponding storage areas 16b and 16c of the fire receiver RE. In other words, the set data type includes its own node number, network data, system data, terminal data, and terminal link table. Here, the network data and system data are sent to a plurality of main repeaters LM and distributed fire receivers RE. It is an example of common setting data that is common, and the own node number, terminal data, and terminal link table are examples of individual setting data that are individual to the main relay LM. The system data, terminal data, and terminal link table are similar in configuration to the storage unit 14 of the fire receiver RE as shown in FIG. Is omitted.

  In the distributed fire alarm system configured as described above, for example, when the main relay LM # 5 detects a state change (for example, fire detection) of its own terminal device AD1, the main relay LM # 5 The state information (fire information) of the terminal device whose state has changed is given its own node number # 5, the terminal address AD of the terminal device whose state has changed, and the terminal data (type ID, sensitivity level KL, storage time) When the fire receiver RE receives the status information via the LAN, the fire receiver RE sends the status information to the node number #, the terminal address AD, and the terminal. The data is stored in the work area 17 together with the data, and further displayed on the display unit 12. Thus, even if the fire receiver RE is configured not to store the individual setting data (for example, terminal data) of all the main repeaters LM in the setting data storage unit 16, the fire receiver RE is individually provided together with the disaster prevention information as in the past. The configuration data can be displayed on the display unit 12, and the administrator can confirm in detail the state change in the system.

  In addition, when the fire receiver RE actively acquires and displays the individual setting data (for example, when checking the setting data) except when the state of the terminal device changes as described above, the fire receiver RE Can also request and acquire the individual setting data stored in the setting data storage unit 26 of the main relay LM from the main relay LM.

  By the way, in the distributed fire alarm system configured as described above, the settings stored in the setting data storage units 16 and 26 of the fire receiver RE and the main relay LM using the database creation device 60 of FIG. Data can be rewritten and updated.

  FIG. 8 is a block diagram showing the configuration of the database creation device. In FIG. 8, reference numeral 60 denotes a database creation apparatus as an example of a setting data register, which is constituted by a general-purpose personal computer or the like and has a slot SL2 in which a memory card MC1 can be freely attached, an input unit 61, a display unit 62, and a database creation. It is a control unit that controls the entire apparatus, and is a database creation unit 63 that is an example of setting data transfer means, and a storage unit 64 that is an example of a setting data storage unit, which is composed of a hard disk, etc., a fire receiver RE, and a main The connector 65 is an example of a connection port that is attached to and detached from the ports 18 and 28 of the relay LM.

  The database creation device 60 includes a storage unit 64 as a setting data storage unit that stores update setting data of the main relay LM or the distributed fire receiver RE, and update setting data stored in the setting data storage unit 64 And a database creation unit 63 as setting data transfer means for individually specifying and transferring to the main repeater LM or the distributed fire receiver RE via the transmission line, and the main repeater LM or It is an example of the setting data registration device comprised so that the setting data of the distributed fire receiver RE could be rewritten.

  Next, rewriting / updating work of setting data of the fire receiver RE and the main relay LM will be described. First, the worker inserts the memory card MC1 into the slot SL2, inputs data via the input unit 61, and based on the data input from the input unit 61, the database creation unit 63 sends setting data for updating. Create and write to the memory card MC1 and the storage unit 64.

  Then, the worker connects the connector 65 to any one of the ports 18 and 28 (the empty ports 18C and 18B in FIG. 3 and the empty ports 28C and 28D in FIG. 5) of the fire receiver RE and the main relay LM. For example, the connector 65 is connected to the empty port 18C (input / output port a) of the fire receiver RE. Then, the node number # of the host device whose setting data is to be updated and the setting data type (for example, terminal data) that is desired to be updated are input via the input unit 61, and the node number # specified by the input unit 61 is set. The setting data for updating the data type is taken out from the storage unit 64 by the database creation device 63, assigned the node number # and the setting data type, and transferred to the transmission / reception port 18 </ b> C of the LAN interface 11 through the connector 65.

  In the fire receiver RE (# 1), when the update setting data signal is input to the input / output port a of the transmission / reception port 18C, the transmission / reception port 18C outputs the signal from the output port c to the first-arrival determination retransmission circuit unit 37. To do. Then, the first-arrival determination retransmission circuit unit 37 closes the input port b of the transmission / reception port 18C, closes the output ports c of the other transmission / reception ports 18A to 18B and 18D for a predetermined time, and changes from the open input port b to another transmission / reception port 18A. The update setting data signal is output to .about.18B and 18D. The other transmission / reception ports 18A to 18B output the input update setting data signal from the input / output port a to the LAN.

  The update setting data signal is notified to the control unit 15 via the transmission control unit 35 and the transmission / reception unit 36. If the node number # is assigned, the control unit 15 takes in the received setting data type setting data and rewrites and updates the setting data type setting data stored in the setting data storage unit 16. To do.

  On the other hand, the # 2 and # 5 main repeaters connected to the fire receiver via LAN have the update setting data signal input to the input / output port a of one transmission / reception port 28 of the LAN interface 21. Similar to the operation of RE (# 1), an update setting data signal is output from the input / output port a of the other transmission / reception port 28 to the LAN. In addition, the setting data signal for update is notified to the control unit 25 via the transmission control unit 45 and the transmission / reception unit 46, and the control unit 25 receives the received setting data when its own node number # is given. The setting data of the type is taken in, and the setting data of the setting data type stored in the setting data storage unit 26 is rewritten and updated.

  In this way, each host device takes in the update setting data signal and sends it to the adjacent host device connected via the LAN, so that each host device can update the update setting data. The signal can be received and rewritten and updated as necessary.

  In addition, the database creation device 60 individually designates each host device LM and RE by individually specifying the node number # of the host device whose setting data is to be updated and the setting data type which is desired to be updated. Since replacement updating can be performed, when the setting data stored in each host device is different, the updating operation can be performed in a detailed manner.

  By the way, since common setting data (for example, system data, etc.) is common among all the host devices, when updating the common setting data, all of the plurality of main repeaters LM and the distributed fire receiver RE are updated by an operator. The common setting data of all the host devices LM and RE can be updated by designating and transferring the node number # of the node (specifying the common node number # 0 meaning the designation of all the node numbers #) However, if there is a node device that is not updated, data cannot be matched, which causes a problem in system operation.

  In order to cope with this, for example, the fire receiver RE sends a SUM value request signal of the common setting data to each main repeater LM periodically or when the common setting data is updated. Each main repeater LM that has received the SUM value request signal calculates and sends out the SUM value of the common setting data, is received by the fire receiver RE, and matches the SUM value of the common setting data in the fire receiver RE1. If they do not match, it is possible to check the consistency of the common setting data by displaying an abnormal indication to that effect.

  Alternatively, when the common setting data is updated, the host device LM, RE sends the SUM value request signal of the common setting data to the other host devices LM, RE, and receives the SUM value request signal. The other host devices LM and RE calculate and send the SUM value of the common setting data, and the host devices LM and RE with the updated common setting data receive and receive the common setting data in the host devices LM and RE. It is determined whether or not the SUM value matches. If not, the common setting data is sent to the other host devices LM and RE that do not match, and the other host devices LM and RE that do not match are transmitted. The common setting data can be automatically matched by receiving and updating the common setting data.

  Further, if the SUM values do not match, the SUM value having the largest number of matches between the SUM value of the distributed fire receiver RE and the SUM value of each main repeater LM is set as a normal SUM value, and the distribution having the SUM value A host device such as a fire receiver RE can also send normal common setting data to other host devices with an abnormal SUM value, rewrite and update them, and automatically match them. .

  The confirmation of the SUM value of these common setting data may be confirmed individually for each type of common setting data, that is, for each network data and system data, or may be confirmed as a whole.

  According to the above embodiment, a plurality of main repeaters LM that monitor and control a plurality of terminal devices connected via the signal line L, and the plurality of main repeaters LM are connected via a LAN as a transmission line. The distributed fire receiver RE includes a distributed fire receiver RE that transmits and receives disaster prevention information to and from the plurality of main repeaters LM. The distributed fire receiver RE includes the distributed fire receiver RE. A storage unit 14 (setting data storage area 16) as a receiver memory for storing setting data of the RE, and a receiver LAN interface 11 for receiving setting data for updating the distributed fire receiver RE via the transmission line; A receiver control unit 15 that rewrites and updates the setting data of the distributed fire receiver RE stored in the receiver memory 14, and the plurality of main repeaters LM are configured to set the main repeater LM. De A storage unit 24 (setting data storage area 26) as a main relay memory for storing data, a main relay LAN interface 21 for receiving setting data for updating the main relay LM via the transmission line, A main repeater control unit 25 that rewrites and updates the setting data of the main repeater stored in the main repeater memory 24. The receiver LAN interface 11 or the main repeater LAN interface 21 is configured to receive the distributed reception. Since the database creation device 60 as a setting data register for storing the setting data for update of the machine RE or the main relay LM is connected and sends the setting data for update to the transmission line, the LAN interface 11 or 21 If the setting data register 60 is connected, the setting data can be updated. When the setting data is updated, the update is performed. Each host device LM Thai setting data is used, went up to the installation site of the RE, it is not necessary to perform the update operation, update work is simple.

  In addition, since the distributed fire receiver RE and the plurality of main repeaters LM are all provided with ports 18 and 28 as connection ports for connecting the setting data register 60, connection ports of any of the host devices LM and RE. The connection port 65 of the setting data registration device 60 can be connected to 18 and 28 to update the setting data of arbitrary host devices LM and RE.

  The plurality of main repeaters LM include network data or system data as common setting data common to the plurality of main repeaters LM and the distributed fire receiver RE, and a plurality of terminals connected to the main repeater LM. The terminal data relating to the device, the individual individual setting data such as the terminal linkage table in the main repeater LM are stored in the main repeater memory 24, and the disaster prevention information is transmitted when the disaster prevention information is transmitted via the transmission line. A control unit 24 is provided as individual setting data sending means for giving and sending individual setting data related to information. The distributed fire receiver RE stores the common setting data in the receiver memory 14 and transmits it. As individual setting data acquisition and display means for receiving disaster prevention information and individual setting data sent from the main relay LM via a line and displaying them on the display unit 12 as display means Since the control unit 15 is provided, even in the conventional configuration, the distributed fire receiver RE does not store the individual setting data of all the main repeaters LM in the receiver memory 14 as in the conventional case. The individual setting data can be displayed on the display unit 12 together with the information. And the memory amount of the receiver memory 14 can be reduced compared with the past. In addition, since the arrangement configuration of the individual setting data is set as described above, when the setting data of a certain main repeater LM is updated, in the conventional arrangement of the individual setting data, the main repeater LM and the distributed fire receiver RE are updated. However, only the main repeater LM needs to be rewritten and updated, and the individual setting data of each main repeater LM is updated. Each time, the distributed fire receiver RE does not need to update the corresponding individual setting data. Thereby, for example, the transfer time of the individual setting data through the transmission line is shortened, and adverse effects such as collision with other disaster prevention information on the transmission line can be reduced.
