The structure information storage unit 109 is a unit that stores information about the building structure of a building to which the disaster prevention system 1a is applied, and holds the structure information 109a of the building and the installation information 109b about the disaster prevention drive device.

The structural information 109a of the building is information on the range and height of each room inside the building, the positions of walls and doors, and is created based on the architectural drawing or a CAD system data file into which the architectural drawing is input. To be done. An example of a procedure for creating the structure information 109a will be described with reference to FIGS. First, divide the entire building into zones. FIG. 5 is an example of a plan view showing the structure of each floor of the building. For example, as shown in this figure, the interior of the building is divided into areas on each floor, such as an office A, an office B on the fourth floor, a corridor, a conference room, and a toilet.

Next, a predetermined position of the building is defined as a reference point Po, and the three-dimensional space forming each area is defined by the coordinates of the vertices of each area and the shape of each area represented by the reference point Po as the origin. Specify and register. For example, the southeastern end of the ground on the first floor is set as the reference point Po, and the conference room 8 shown in FIG.
From the position of each one of the vertices and the position of the reference point Po, the coordinates of each vertex when the reference point Po is the origin are obtained. This state is shown in FIG.

Based on the coordinates thus obtained,
Each area is defined as a three-dimensional space. An example of the area defined in this way is shown in FIG. This figure shows a case where a 4-story building is divided into areas for each floor, and each area is defined by the coordinates of eight vertices. For example, eight vertices (0, 0, Z2) , (X1,
0, Z2), (0, Y1, Z2), (X1, Y1, Z
2), (0, 0, Z3), (X1, 0, Z3), (0,
The space surrounded by (Y1, Z3) and (X1, Y1, Z3) is defined as the second floor.

On the other hand, the disaster prevention device installation information 109b is information relating to the mounting positions of the disaster prevention drive devices 121 to 12n and their affected areas. For example, for the alarm bell on the 4th floor, it is information on the attached coordinate position and the entire 4th floor, which is the audible range of the ringing sound, and for the sprinkler of the office B, the coordinate position and the extinguishable range. It is the information of the office B and the conference room.

The position information storage means 108 stores the sensor installation information 1 regarding the mounting positions of the sensor devices 111 to 11n.
08a is retained. This sensor installation information 108a
Is composed of the mounting position of the sensor device and the area in the building to which the mounting position belongs. Sensor device 111 to
The attachment position of 11n is represented as a coordinate position from the reference point Po, similar to the position information stored in the structure information storage unit 109. In addition, the sensor devices 111 to 11
The area in the building to which n belongs is the structure information storage means 10.
It can be specified by comparing the coordinates of the vertices of each area held in 9 with the position information of the sensor devices 111 to 11n and examining the area surrounding the sensor devices 111 to 11n by all the vertices.

For example, with respect to the smoke sensor in the conference room on the 4th floor, the x-coordinate, y-coordinate and z-coordinate of the position where it is attached and the area in the building called the "4th floor conference room" are stored and held. . The position information collecting unit 105 inquires of the sensor devices 111 to 11n about the mounting position by the communication unit 100 and collects the position information.
The position information thus obtained and the structure information storage means 1
Based on the structure information 109a of the building held in 09, the installation information 108a regarding the sensor device is created.

The interlocking table creating means 106 creates a disaster prevention equipment interlocking table according to a predetermined interlocking rule based on the information held in the position information storing means 108 and the structure information storing means 109. The interlocking rule is based on the sensor device 11
1 to 11n and the disaster prevention drive devices 121 to 12n are interlocked with each other, a general rule is predetermined for each type of sensor device, and when there is a interlocking rule specific to the application target of the disaster prevention system. Is a rule formed by adding this specific rule.

For example, as an interlocking rule for a smoke sensor, when a fire is detected, all alarm bells in the building are rung, and the exhaust ducts on the floor where the sensor device is installed and on the floor immediately above are activated, The rule can be used to close the fire door in the area where the sensor device is installed and activate the sprinkler in that area. According to this rule, the interlocking table creating means 106 determines the disaster prevention drive devices 121 to 12n to be interlocked for each of the sensor devices 111 to 11n installed in the building, and automatically creates the disaster prevention device interlocking table 102a. Interlocking table storage means 1
02 is stored. That is, the interlocking rule is set for each sensor device 11
1 to 11n and individual sensor devices 111 to 11
The disaster prevention device interlocking table that specifically identifies the disaster prevention drive devices 121 to 12n interlocked with n is created.

Therefore, when the building structure information 109a and the disaster prevention device installation information 109b are created and stored in the structure information storage means 109, the disaster prevention device interlocking table is automatically created after the installation of the sensor device. You can Further, even if the mounting position of the sensor device is changed or the sensor device is added, the disaster prevention device interlocking table can be automatically updated.

The map data creating means 107 creates map data 104a to be displayed on the display device D based on the information held in the position information storing means 108 and the structure information storing means 109, and stores it in the map data storing means 104. Store. This map data 104a is the structure information storage means 10
9, a plan view of the building including the disaster prevention drive devices 121 to 12n is created, and based on the information of the position information storage means 108, the sensor devices 111 to 1 are added to the plan view.
It is created by displaying 1n symbols at their respective installation positions.

Therefore, when the building structure information 109a and the disaster prevention device installation information 109b are created and stored in the structure information storage means 109, the disaster prevention display map data is automatically created after the installation of the sensor device. be able to. Further, even if the mounting position of the sensor device is changed or the sensor device is added, the disaster prevention display map data can be automatically updated.

Further, in such a disaster prevention system 1a, since each sensor device 111 to 11n can be identified by its position information, it is not necessary to set an address when constructing the sensor device. That is, since the same type of sensor device is not attached to the same position more than once, if the central processing unit can acquire the type and attachment position of the sensor device that is sending the detection signal, the sensor device can be identified by the address. No need to identify. Therefore, unlike the conventional disaster prevention system, it is not necessary to set the address when mounting the sensor device, and whether or not the correct address is set for each sensor device is tested on a trial basis. There is no need to detect and confirm.

It is removable. When mounting the sensor device 11b, the mounting operator connects the output terminal of the position measuring device 25 to the position information input terminal T of the sensor device 11 '. Therefore, the position information measured by the position measuring device 25 is input to the sensor device 11b, and is temporarily stored in the position information storage means 24.
Stored in. After that, the installation worker is
The position measuring device 25 is removed from b, and the installation work is completed.

The position information held in the position information storage means 24 in this manner is used as the communication means 20 of the sensor device 11b.
Is sent to the central controller 10a when a request is received from the central controller 10a. Therefore, even if the sensor devices 111 to 11n are not provided with the position detection means 22, each sensor device can obtain the position information by connecting the position measuring device 25, and thus the central control device 10a can obtain the position information. The position information of the sensor devices 111 to 11n can be collected. That is, the disaster prevention device interlocking table and the disaster prevention display map can be automatically created based on this position information.
