Description

  The present invention relates to a fire receiver, and more particularly to a fire receiver capable of storing change history information when various setting contents are changed at a site where the fire receiver is installed.

  The fire receiver is connected to various sensors installed at various predetermined locations via signal lines, and can collect information on each sensor. As such a fire receiver, it is known that a storage medium (memory card) in which various setting data such as interlocking information is stored in a database is used. This memory card is readable and writable and non-volatile.

  When performing various settings on a conventional fire receiver, first, a dedicated tool (database creation device) is used to create various setting data and write them to a memory card. Then, by removing the memory card that has been written from the dedicated tool and inserting it into the fire receiver, new contents are set in the fire receiver.

  In addition, when changing the setting data according to each installation environment, the desired data can be changed directly on the fire receiver with the memory card inserted. It is written in the memory card. Furthermore, there is also a fire receiver provided with an upload request notification means for requesting the user to upload the changed setting contents to the database on the database creation device side when the setting contents in the memory card are changed. (For example, refer to Patent Document 1).

  According to such a fire receiver of Patent Document 1, the setting can be changed immediately without using a dedicated tool on site. Furthermore, the latest data can be uploaded to the database creation device side by removing the memory card from the fire receiver and inserting it into the database creation device in response to the upload request. As a result, the setting content of the database (first database) provided in the memory card and the setting content of the database (second database) provided in the database creation device can be quickly matched. .

Further, the fire prevention door D111, the smoke exhauster D112, the shutter D113, and the leaning wall D114 are connected to the smoke prevention control relay D11. With such a configuration, the fire receiver 20 collects information from various sensors and the like installed at various predetermined locations.

  The database creation device 30 is a dedicated tool for creating various setting data used by the fire receiver 20. Various setting data created by the database creation device 30 is written to the memory card 40. Then, the new contents are set in the fire receiver 20 by inserting the memory card 40 that has been written into the fire receiver 20.

  When the fire receiver 20 in the present invention rewrites the data in the memory card 40 on the fire receiver 20 side, the change history content is stored in the memory card 40 and displayed as necessary. This is a technical feature. Therefore, the technical features of the present application will be described in detail below based on the drawings and flowcharts.

  FIG. 2 is a configuration diagram of the fire receiver according to Embodiment 1 of the present invention. The fire receiver 20 in FIG. 2 includes fire information processing means 21, transmission / reception control means 22, database changing means 23, input / output control means 24, display operation unit 25, and change history information registering means 26. Further, the memory card 40 is connected to the input / output control means 24 by being inserted into a slot (not shown) provided in the fire receiver 20 so that the contents can be read and written. The printer 50 also has a configuration that can be connected to the input / output control means 24. The input / output control means 24 is provided with a dip switch SW1 that is operated when the memory card 40 is attached to or detached from a slot (not shown).

  The fire information processing means 21 processes information collected from various sensors as shown in FIG. 1 via the signal line SG. Further, the database changing unit 23 rewrites various setting data in the memory card 40 in accordance with the contents of the change operation by the display operation unit 25. These functions are provided in existing fire receivers.

  On the other hand, the storage of the change history content, which is a technical feature of the present invention, is realized by the change history information registration means 26. Therefore, the operation of the change history information registration unit 26 will be described in detail along a series of operational flows.

When the fire receiver 20 reads various setting data and then changes a part of the setting data on the fire receiver 20 side, a series of operations for leaving the change history is performed by the following steps (first step to first step). 4 steps).
[First step]
Various setting data created by the database creation device 30 is stored in a storage unit in the database creation device 30 as a master database. The master database in the database creation device 30 corresponds to a second database.

[Second step]
In order to deploy various setting data created by the database creation device 30 to a desired fire receiver 20, a memory card 40 is inserted into the database creation device 30, and various setting data is copied as an operation database into the memory card 40. To do. The operation database in the memory card 40 corresponds to the first database.

[Third step]
On the fire receiver 20 side, after the memory card 40 is inserted and various setting data are read, the first operation in the memory card 40 is performed based on the operation from the display operation unit 25 of the fire receiver 20 as necessary. Change part of the contents of the database according to the installation location.

At this time, the change history information registration unit 26 creates change history information associated with the setting change and stores it in the memory card 40. Moreover, since the content of the first database in the memory card 40 is changed, there is a deviation from the content of the second database. Therefore, the content of the first database after the change in the memory card 40 is created as a database. An upload request for urging to synchronize by overwriting the second database in the apparatus is displayed.
[Fourth step]
In order to rewrite the master database, the memory card 40 storing the latest various setting data after the change is removed from the fire receiver 20, inserted into the database creation device 30, uploaded, and the contents of the second database Is overwritten with the contents of the first database. At the same time, the change history information is also uploaded to the storage unit of the database creation device 30.

  An example of a detailed procedure of the second step to the fourth step in the series of operations described above will be described using a flowchart. FIG. 3 is a flowchart showing a flow of a series of processes of the fire receiver according to Embodiment 1 of the present invention. The operator changes various setting data by operating the display operation unit 25 of the fire receiver 20 on the site side (step S301). At this time, in order to prevent the setting data from being easily changed, a password input may be required when changing a specific setting content.

  Next, the changed setting data is recorded in the memory card 40 by the database changing means 23, whereby the contents of the first database are rewritten (step S302).

  Next, the change history information registration unit 26 creates change history information corresponding to the rewrite content in step S302 and stores it in the memory card 40 (step S303).

  Next, the database changing unit 23 displays an upload request for urging to synchronize the contents of the first database after the change in the memory card 40 by overwriting the second database in the database creation apparatus 30. It is displayed on the operation unit 25 (step S304).

  Next, the database changing unit 23 checks whether or not the memory card 40 has been removed for uploading (step S305). For example, the database changing means 23 can confirm this state by reading that the dip switch SW1 has been turned ON by the operator when removing the card.

  The database changing unit 23 continues displaying the upload request in step S304 until it can be confirmed that the memory card 40 has been removed. On the other hand, if it is confirmed in step S305 that the memory card 40 has been removed, the database changing unit 23 deletes the upload request display (step S306).

  Next, the operator inserts the removed memory card 40 into the database creation device 30 and copies the contents of the first database to the second database (step S307). As a result, the contents of the first database, which is the latest setting data after the change, are uploaded to the second database serving as the master. At the same time, the change history information is also uploaded to the storage unit of the database creation device 30.

  Next, the operator returns the memory card 40 to the fire receiver 20 and turns off the dip switch SW1 (step S308). Next, the change history information registration unit 26 determines that the change history information in the memory card 40 has already been uploaded to the database creation unit because SW1 is turned off, and can erase the change history information ( Step S309).

  It is not necessary to erase all of the change history information, and depending on the capacity of the memory card, if the change history information exceeds the predetermined capacity, the old data is stored so that it falls within the predetermined capacity. It is also possible to delete only. Alternatively, instead of the determination by SW1, for example, the latest 100 data may be saved as a history and always deleted sequentially from the oldest one.

  As described above, whenever the contents of the first database in the memory card 40 are rewritten on the site side, the change history information is stored in the memory card 40. The change history information can be displayed on the display operation unit 25 provided in the fire receiver 20 as necessary. As a result, it becomes possible to easily return the setting data by referring to the past data or to set new data based on the past history according to the actual operation status.

  As an example, if the setting data is changed by multiple adjustments at the site so that false alarms do not occur with a sensor installed in a kitchen, etc., if you keep the change history at that time, the next time you adjust Can be used as a reference. Even if a false alarm occurs, if the alarm is not set from the beginning, the alarm will be delayed accordingly. Therefore, by referring to past history data, it is possible to obtain optimum setting data for each installation environment at the site.

  In addition, when the data adjustment is completed and the change history information is uploaded to the database creation device 30 at the same time as the new setting data, the change history information is deleted when the memory card 40 is returned to the receiver. It is possible to prevent the memory capacity from overflowing.

Next, specific examples of various setting data stored in the database and specific examples of the change history information will be described.
As setting data regarding various sensors, for example, the following three types of setting data can be considered.
[Setting data 1] Attention level, fire level, failure level threshold of the sensor The fire information processing means 21 in the fire receiver 20 is compared with the analog value periodically notified from each analog sensor. This is a predetermined value for determining whether to issue an alarm.

[Setting data 2] Alarm state duration time When the fire information processing means 21 in the fire receiver 20 compares the analog value periodically notified from each analog sensor with the threshold level and performs each alarm. This is a predetermined time for giving an alarm for the first time when an alarm value is continued for a certain period of time or longer without immediately giving an alarm.

[Setting data 3] Option message When the fire information processing means 21 in the fire receiver 20 performs each alarm, the location displayed on the display operation unit 25 together with the sensor number so that the alarm occurrence location can be easily understood. Name data.

  The threshold of setting data 1 and the duration of setting data 2 vary depending on the installation environment of each sensor. In such a case, in addition to the function of easily changing the setting data of the fire receiver on the site side, the function of accumulating the change history information as appropriate and displaying it as necessary becomes important. By utilizing this change history information, the setting data can be narrowed down to the optimum value on the site side or returned to the previous data according to the installation environment at each site.

  Next, details of the change history information will be described. FIG. 4 is a diagram showing an example of the change history information in the first embodiment of the present invention. In FIG. 4, as the contents of the change history information, six items of NO, change date, change contents (changed setting data name), data before change, data after change, and address are illustrated.

  Such change history information can be displayed on the display operation unit 25 as necessary. For example, when the operator changes and adjusts the attention level of the same sensor as NO3, NO5, and NO6 in the change history information, a warning information is frequently generated at 4.6% / m, so that NO6 is 5. Change to 7% / m, warnings will not be generated, change to 5.0% / m with NO5, warnings will occur frequently, change to 5.3% / m with NO3 However, if a warning is occasionally generated, the setting can be changed to an optimum value next time, for example, by setting it to 5.5% / m.

  As described above, according to the first embodiment, when the contents of various setting data in the operation database of the fire receiver are changed on the site side, the change history information of the changed various setting contents is stored in a nonvolatile memory. You can register on the media. As a result, the change history information can be read, viewed, and managed by a general-purpose personal computer or the like.

  Furthermore, when the contents of various setting data in the operation database are changed, an upload request can be notified to the user. As a result, the changed operation database can be uploaded to the master database provided in the database creation device, so that the master side can be rewritten with the latest data.

  Furthermore, the changed setting data name, the setting data before the change of the changed setting content, and the setting data after the change are registered as the change history information of the changed various setting data. As a result, it can be confirmed how the contents of the changed setting data have changed. As the change history information of various setting data, for each changed setting data, the setting data before the change and the setting data after the change are registered for the first time, and only the setting data after the change is registered after the second time. Even if it does, it can be confirmed how the content of the setting data has changed.

  Furthermore, when the contents of various setting data in the operation database are changed, when the upload to the master database provided in the database creation device is completed, the change history information is also uploaded to the master storage unit at the same time. The change history information of the storage medium can be erased. As a result, it is possible to prevent the memory capacity from overflowing and reliably store the latest change history information.

  Further, the change history information can be displayed on the display / operation unit, or can be printed by connecting a printer, so that the change history can be easily viewed and managed.
