Here, in the communication between the local controller (LC) 3 and the transceiver (RCV) 4, the fire detection signal from the fire detection sensor 1 and the control signal to the smoke prevention terminal 2 include the fire detection sensor 1 and Identification information for identifying the smoke prevention terminal 2 is added and transmitted. Reference numeral 6 denotes a display device (CRT) which displays the status of the fire detection sensor 1 and the smoke prevention terminal 2 on a screen according to a signal from a transceiver (RCV) 4. The transceiver (RCV) 4
An interlocking table indicating an interlocking relationship between the fire detection sensor 1 and the smoke prevention terminal 2 is provided therein. When a fire detection signal is input, the interlocking table is searched to find an appropriate smoke prevention terminal 2. Then, a control signal for operating the smoke prevention terminal 2 is selected and sent.

Here, the interlocking table will be described with reference to FIG. What is shown in the figure is an interlocking table A having single interlocking relation data, in which an individual interlocking relation between an individual fire detection sensor 1 and a smoke control terminal 2 to be interlocked when a fire is detected. The type data and the installation location data are registered as identification information of the fire detection sensor 1 and the smoke prevention terminal 2. The installation location data is based on the data of the ridge, floor, and district. The example of registration on the first line is that when the fire detection sensor 1 of the type S1 of the 1st floor and 1st district of one building detects a fire, for example, the smoke detection terminal 2 of the 1st floor and 1st floor of the 1st building is linked. It is controlled. In the example of FIG. 7, six types of such single interlocking relationship data are stored in the interlocking table A.

[0004] When the actual interlocking control is performed using the interlocking table A, first, a fire detection sensor 1 installed near a fire occurrence location in a building transmits a fire detection signal to a local controller (LC) 3. The local controller (LC) 3 adds an identification signal to the fire detection signal and sends it to the transceiver (RCV) 4, where the transmitter / receiver (RCV) 4
Then, upon receiving this signal, the interlocking table A is searched,
After selecting all the smoke control terminals 2 corresponding to the corresponding fire detection sensor 1, a control signal to which identification information of these smoke control terminals 2 is added is transmitted. This control signal is transmitted to each smoke control terminal 2 via the local controller (LC) 3 to execute the interlocking control.

[0005]

However, in the above-described disaster prevention system, the control terminal (fire detection sensor 1) registered in the interlock table A and the controlled terminal (smoke prevention terminal 2) are individually linked. When there are many relationships, there is a problem that it takes much time to create data.

[0006] The present invention has been made in view of the above points, and an object of the present invention is to provide a disaster prevention system in which the number of registrations in an interlocking table is reduced.

According to a fourth aspect of the present invention, in the second aspect, a group type is entered in a control terminal type column of the group interlocking relationship common table.
The interlocking relationship is hierarchically shown.

[0011]

According to the present invention, when a fire detection is generated at a control terminal including a fire detection sensor or the like, an appropriate interlocking control of a controlled terminal such as a smoke prevention terminal is performed. A group interlocking relation common table that stores data indicating a common part of a group having a common relation pattern and a group interlocking relation representative table that stores data indicating a different part are provided, and corresponding data in both tables are added. Thus, each single interlocking relationship is obtained.

Further, the data structure of the group interlocking relation representative table is composed of a group type and a group location, and the data structure of the group interlocking relation common table is composed of a group type, a control terminal type, a control terminal installation location, and a receiving terminal. It consists of the control terminal type and the installation location of the controlled terminal.

Further, each of the tables is realized with the same table configuration by using specific data.

Further, the group relation is hierarchically shown by putting the group type in the column of the control terminal type in the group relation common table.

[0015]

An embodiment of the present invention will be described below with reference to the drawings. Since the basic configuration of the disaster prevention system according to the present invention is the same as that shown in FIG. 6 described as a conventional example, the same portions are denoted by the same reference numerals and description thereof will be omitted. A feature of the present invention is that, in the disaster prevention system shown in FIG. 6, as the table held by the transceiver (RCV) 4, the common data is registered for the combination of the same pattern in the interlocking relationship. Group linkage relationship common table B
And a group interlocking relation representative table C for registering different data.

FIG. 1 is a diagram showing an example of a group linkage relationship common table B and a group linkage relationship representative table C according to an embodiment of the present invention. Now, consider a case where the same interlocking relationship as the interlocking relationship shown in the interlocking table A of FIG. 7 is registered. In the six single interlocking relationships, the interlocking relationship in the first to third rows (referred to as GROUP1) and the interlocking relationship in the fourth to sixth rows (referred to as GROUP2) have the same pattern. That is, GROUP 1 and GROUP 2 differ only in the floor where the fire detection sensors S1 and S2 as the control terminals and the damper as the controlled terminal are installed by one floor, and the other identification information is the same. Therefore, as shown in FIG. 1A, a group interlocking relationship common table B is registered as a common pattern of GROUPs 1 and 2, and as the different data, GROUP is used as shown in FIG.
Two rows of data for each of 1 and 2 are registered as a group association relation representative table C. The interlocking table A shown in FIG. 7 is automatically created from the two tables B and C. That is, the interlocking relationship of GROUP1 is determined by adding together data of buildings corresponding to GROUP1 in the group interlocking relationship common table B and group interlocking relationship representative table C, floors, and districts. Is created, and the interlocking relationship of GROUP2 is such that the data of buildings corresponding to GROUP2 of the group interlocking relationship common table B and the group interlocking relationship representative table C, the floors, and the districts are added together. As a result, the interlocking relationship of the fourth to sixth rows of the interlocking table A is created.

According to this embodiment, when registering the interlocking relationship, conventionally, (the number of common parts in the pattern) × (the number of patterns) (six rows in the case of the interlocking table A in FIG. 7)
Need to be registered, only the number of (the number of common parts in the pattern) + (the number of patterns) needs to be registered (five rows in FIG. 1). Therefore, the more the number of registrations in the same pattern is, the more efficient it becomes.

It should be noted that interlocking relationships that do not belong to the GROUP of the same pattern may be individually registered in the interlocking table A as single interlocking relationship data.

The single interlocking relation data is shown in FIG.
As shown in, the control terminal type and its installation location, and the controlled terminal type and its installation location,
As shown in FIG. 2B, if a group type column is further provided, the table configuration becomes the same as that of the group interlocking relationship common table B. Then, if specific data having a meaning of invalid (may be blank) is entered in this group type column, the interlocking table A for registering single interlocking relation data with the same table configuration as the group interlocking relation common table B is created. Can be configured.

Further, a group interlocking relation representative table C
As shown in FIG. 3A, is composed of data of a group type and a group location, and the group location is composed of data of a building, a floor, and a district. On the other hand, in comparison with the table configuration of the group interlocking relationship common table B, when looking at the data configuration excluding the group type, the controlled terminal type, and the installation location, there is a difference between the control terminal and the group. They are equal in the sense that they are shown. Therefore, specific data (may be blank) for invalidating the columns of the group type, the controlled terminal type, and its installation location in the same data configuration as the group interlocking relationship common table B is entered in each of the columns. As shown in (b), the group interlocking relation representative table C can be configured.

As described above, the interlocking table A indicating the single interlocking relation data, the group interlocking relation common table B, and the group interlocking relation representative table C can be realized by one table configuration.

As shown in FIG. 4, if a group type other than the control terminal type can be entered in the control terminal type column in the group interlocking relation common table B, the grouping is used. The interlocking relationship can be performed hierarchically as shown in FIG. In the example shown in FIG. 4, the group interlocking relationship common table B whose group type is indicated by GROUP2 is composed of two single interlocking relationship data and the GROUP interlocking relationship data whose group type is indicated by GROUP3. .

In the above embodiment, an example was described in which the fire detection sensor 1 was used as the control terminal, and the smoke prevention terminal 2 was used as the controlled terminal. However, the smoke prevention terminal 2 is the control terminal. A signal from the smoke control terminal 2 may control another smoke control terminal 2 as a controlled terminal.

[0024]

As described above, according to the first aspect of the present invention, when a control terminal including a fire detection sensor generates a fire detection, an appropriate control of a controlled terminal such as a smoke prevention terminal is performed. In a disaster prevention system such as that described above, there is provided a group interlocking relation common table that stores data indicating a common part of a group having a common interlocking pattern, and a group interlocking relation representative table that stores data indicating a different part. Since each single interlocking relationship is obtained by adding each corresponding data in the table, a disaster prevention system in which the number of registrations in the interlocking table is reduced can be provided. According to the second aspect of the present invention, the data structure of the group interlocking relation representative table includes a group type and a group location, and the data structure of the group interlocking relation common table includes a group type and a control terminal type. Since it is configured with the installation location of the control terminal, the type of the controlled terminal, and the installation location of the controlled terminal, a disaster prevention system with a reduced number of registrations in the interlocking table can be provided.

According to the third aspect of the present invention, since each of the tables has the same table configuration, the memory capacity for storing each table can be reduced.

Further, according to the fourth aspect of the present invention, the interlocking relationship is hierarchically shown by putting the group type in the control terminal type column of the group interlocking relationship common table. The memory capacity to be stored can be further reduced.
