BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improvement of a display controller in a disaster prevention system.

[0002]

2. Description of the Related Art Conventionally, there are a plurality of types of receivers for disaster prevention systems, which are used properly depending on the number of lines to be managed, the scale of a building, and the like. Therefore, it is necessary to prepare a ROM board in the display controller according to its type and capacity, and to change the storage means on the ROM board, and also to change the reading program of the storage means. It was complicated and complicated.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an RO in a display controller is provided.
Mount multiple ROMs on the M board, and receive from these ROMs .
The purpose is to facilitate connection with the receiver by selecting and using the one that is suitable for the system scale managed by the receiver.

[0004]

In order to achieve the above object, the present invention according to claim 1 proposes a display necessary for an abnormality occurrence by receiving an alarm signal from a plurality of sensors on the receiver side. In a disaster prevention display system in which information is systematically displayed by a display device, a display controller is interposed between the receiver and the display device at the time of occurrence of an abnormality, and the display controller has a system scale managed by the receiver. A plurality of ROMs having different capacities and storing data managed by the receiver, selection switching means for selecting the plurality of ROMs, and display when an abnormality occurs And a signal processing unit for controlling display of information. Claim 2
According to the present invention, the selection switching means is a jumper setting section.

[0005]

According to the first aspect of the present invention, in the disaster prevention display system, the notification signal is received from the plurality of sensors at the receiver side and the display information necessary for the occurrence of an abnormality is systematically displayed by the display device. It is interposed the display controller between the receiver and when abnormality occurs in the display device, the display con
Multiple ROMs are prepared for the Troller with different capacities according to the system scale managed by the receiver.
Each of these ROMs stores data managed by the receiver. Then, the selection switching means selects the ROM according to the system scale managed by the receiver . Then, the signal processing unit controls the display device to select the selected RO.
Since displaying the display information at the time of abnormality occurrence by M, depending on the size of the disaster display system, the display controller
The data setting can be easily switched. According to the second aspect of the present invention, since the selection switching means is the jumper setting section, the ROM switching selection can be easily performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the disaster prevention information system according to the present invention will be described below with reference to the drawings. FIG.
FIG. 3 is a block diagram of a disaster prevention display system.

In the figure, the disaster prevention display system is shown as a detector K.
If, for example, a fire occurs in the room in which the sensor is installed, the sensor K detects and sends an alarm signal to the receiver J. Then, the receiver J becomes the display controller H.
Signal to the input port 4 of. In the display controller,
Necessary information is sent to a plurality of display devices from the output ports 5a, 5b and 5c, and the display device (CRT) displays the necessary information.

FIG. 2 is a configuration block diagram of the display controller H. The display controller H is composed of a CPU board A, a mother board B, a monitor display board C, and the like. FIG. 3 is an external perspective view of the display controller. In FIG. 3, a CPU board A, a monitor display substrate C, a power supply terminal 30, a power switch 31, and a fuse 32 are provided on the surface.

In FIG. 2, a CPU board A has a signal processing unit 1, data ROMs 2a and 2b as storage means,
2c, a jumper setting unit 3 as a selection switching unit (claim 2), and an input port 4 and output ports 5a, 5b, 5c via an RS232C interface. The signal processing unit 1 is a CPU 1 that processes signals.
a, a program ROM 1b that stores a program for operating the display controller, a program RAM 1c that stores the state of each sensor by an alarm signal sent from the receiver, and the like. The data ROMs 2a, 2b, 2c are input with data of all lines of automatic fire alarm, gas, smoke control which are managed by the receiver, and the contents of the data are the installation locations of devices such as detectors. (Building, floor, district), equipment type, equipment name, etc. Incidentally, interlocking data between devices may be stored. This interlocking data is a corresponding operation of another device when a certain sensor detects an abnormality. This data ROM2
The capacities of a, 2b, and 2c differ depending on the scale of the system managed by the receiver, and the jumper setting unit 3 is configured to perform jumper connection (short circuit) according to the size of the scale. . FIG. 5 shows this state. The CPU board A has an appearance as shown in FIG. 4, in which 10 is a power supply terminal, 4 is an input port from a receiver, 5a, 5b, and 5c are output ports to a display device. , 11 are data ROMs 2a, 2b, 2c
ROM board for mounting etc., 3 is a jumper setting section, 1
Reference numeral 2 is a connector for connecting to the motherboard B.

The mother board B in FIG. 2 is a wiring board for connecting the CPU board A and the monitor display board C.

The monitor display board C in FIG. 2 comprises a switch (not shown), an LED display section, and a connector for connecting to a mother board. This monitor display board C is
This is for conducting a connection inspection of the display controller H.

Next, the operation of one embodiment of the display controller in the disaster prevention display system according to the present invention will be described. The address lines on the data bus of the display controller are from A1 to A23, among which A22, A2
The capacity of the data ROMs 2a, 2b, and 2c can be selected by setting whether the address lines 1 and A20 are valid or invalid. For example, the data ROM 2a
In order to use, it is effective to short the jumper pin connected to the data ROM 2a. In this way, data ROMs having different capacities can be selected according to the scale of the disaster prevention display system.
Will be standardized. Also, this data ROM2
A program that can read a, 2b, and 2c is resident in the program ROM 1b of the signal processing unit 1, and which of the ROMs 2a, 2b, and 2c is short-circuited is read by a jumper wire, and the operation of the display controller H is performed by this program. Processing.

In this embodiment, as the selection switching means,
Although the jumper setting unit described in claim 2 is used, the jumper setting unit is not limited to this, and other selection switching may be performed.

[0014]

According to the present invention, the display controller has a plurality of storage means, and by switching the storage means by the selection switching means, it is possible to cope with disaster prevention display systems of different scales.
