Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire alarm system including a fire receiver and a plurality of terminals connected to the fire receiver, and more particularly to a display mode on a display unit of the fire receiver. is there.

[0002]

2. Description of the Related Art Conventionally, in a fire alarm system using an R-type fire receiver, when a fire occurs and a fire detector issues an alarm, the display location of the fire receiver indicates the location of the fire detector. For example, the management number is displayed such as No. 3 on the second floor of the first building. By displaying the control number in this way, it was convenient for the manager at the disaster prevention center to know where the fire broke out.

[0003]

However, when an equipment engineer who carries out maintenance and inspection of terminals such as fire detectors actually inspects for malfunctions, etc., only the management number displayed on the fire receiver will cause the malfunctioning terminal. I don't know the exact position of
It is necessary to know the address of the terminal (hereinafter, the address of the terminal is called the physical address). Therefore, the physical address was searched for by using the number management table (interlocking table) of the terminal management number and the physical address, but this comparison table is a table for reading the management number from the physical address, and vice versa. It was extremely troublesome and time-consuming. Therefore, the efficiency of maintenance work was very poor.

By the way, inside the fire receiver, the terminal is managed by a physical address, and the physical address is converted into a management number when displaying. Therefore, an object of the present invention is to display a physical address of a terminal on the display unit of the fire receiver to obtain a fire receiver that is convenient for the facility technician performing maintenance work.

[0005]

Therefore, according to the present invention, when a fire receiver to which a plurality of terminals are connected receives an abnormal signal from the terminal, the address of the terminal that has transmitted the abnormal signal is determined. First storage means for storing,
Second storage means for storing a comparison table between the address of each terminal and the management number of the district in which each terminal is installed;
At the display switching means and at the first operation position of the display switching means, the management number of the area is read from the comparison table of the second storage means based on the address stored in the first storage means. A fire alarm facility is provided, which displays and displays the address stored in the first storage means at a second operation position of the display switching means.

According to another aspect of the present invention,
When a fire receiver to which a plurality of terminals are connected receives an abnormal signal from the terminal, first storage means for storing the address of the terminal that has transmitted the abnormal signal, and the address of each terminal Second storage means storing a comparison table with a management number of the area where each terminal is installed, and the address stored in the first storage means is read out, and the second storage means is read based on the address. And a display unit for displaying the read address and the management number of the district from the above-mentioned comparison table of the storage unit.

[0007]

In accordance with the operation position of the display switching means, the display means switches and displays the management number of the district of the terminal such as the relay or fire detector that has sent out the abnormal signal, or the address of the terminal. In this way, the management number or address of the area can be displayed by operating the display switching means, which is very advantageous when performing work such as maintenance and inspection.

According to another aspect, instead of providing the display switching means, the display means displays the management number and address of the area of the terminal together. In this case, the display means may include, for example, a display part for the management number of the district and a display part for the address.
It is very advantageous when performing maintenance and inspection work.

[0009]

The present invention will be described below with reference to the drawings. Figure 1
1 shows a fire alarm system according to an embodiment of the present invention. A plurality of repeaters C1 to Cn are connected to the fire receiver 10 as terminal devices, and each smoke repeater includes various smoke detectors and heat detectors. A sensor or the like is connected.

In the fire receiver 10, the CPU or the microprocessor 11 that controls the entire system has a read-only storage area ROM 1 storing a system program.
And a read-only storage area ROM2 storing a physical address-management number comparison table, and a temporary storage area RA for work.
M1 and storage area RAM2 for temporary storage of physical addresses
And are connected. Further, a display unit 12 for displaying predetermined data is connected via an interface 13, an operation unit 14 is connected via an interface 15, and a display changeover switch for changing over the display on the display unit 12 is further provided. 16 are connected via an interface 17. Transmission / reception to / from the repeaters C1 to Cn is performed via a serial / parallel conversion circuit 18 that converts serial data into parallel data or vice versa, and a transmission / reception circuit 19 that performs transmission or reception. The display changeover switch 1
6 is actually provided on the operation unit 14 or in the housing of the fire receiver 10.

In the above configuration, when an analog or normal type fire detector, gas leak detector, fire door, smoke evacuator, or other terminal causes an abnormal situation such as a fire alarm, failure, dropout, or wire breakage, The physical address of the terminal that has detected the abnormality transmitted via any of the relays is stored in the storage area RAM2. Since the display changeover switch 16 is normally off, based on the physical address stored in the storage area RAM2, the area (building,
(Floor, number) is calculated from the comparison table stored in the storage area ROM2, and the calculated district is displayed on the display unit 12 as the terminal management number together with the terminal status information.
An example of the comparison table stored in the storage area ROM2 is shown in FIG.

[0012] The fire alarm of the fire detector will be specifically described below as an example. In Fig. 3A, one building 21 out of several buildings is shown. Reference numeral 21 denotes a building from the first basement floor to the fourth floor, for example. FIG. 3B shows a plan view of the second floor of one building 21, and the second floor of the building 21 is divided into areas 1 to 4. And in the area of No. 4, four fire detectors a, b,
c and d are shown installed.

Assuming now that a fire has occurred in the area No. 4 on the second floor of one building, the display section 12 displays the display "No. 4 on the second floor of one building" as shown in FIG. 3C. It is performed as a number display. Although this display shows the approximate position of the fire detector that detected the fire, it is not known which of the four fire detectors a, b, c, and d detected the fire.

When the display changeover switch 16 is turned on, the management number display displayed on the display section 12 is erased,
The physical address such as "1118" of the specific fire detector stored in the storage area RAM2 is D in FIG.
It is displayed as shown in. In this way, when the display changeover switch 16 is pressed, the physical address of the fire detector that has operated is displayed, so that which fire detector has operated can be known. This is particularly advantageous in identifying the location of the fire detector during a failure or test rather than during a fire.

FIG. 4 is a flow chart showing the operation of the fire receiver 10 in the fire alarm system shown in FIG. 1. If there is no abnormal signal from the terminal, there is no need to display it (step 102). N), there is no change in the display changeover switch 16 (N in step 114), and even if there is a change in the display changeover switch 16, no display is made at this point (N in step 116), so the flow is It loops back and is in a standby state without taking any action.

When the abnormal signal from the terminal is first received and the physical address of the terminal is stored in the storage area RAM2, the display is required only at the first reception (Y in step 102), and the display is switched. If the switch 16 is off (N in step 104), the storage area RA
Based on the physical address of M2, the management number is read from the comparison table of the storage area ROM2 (step 106) and displayed on the display unit 12 (step 108). If the display changeover switch 16 is turned on (Y in step 104), the physical address of the storage area RAM 2 is read (step 110) and displayed on the display unit 12 as it is (step 112).

When an abnormal signal from the same terminal is received from the second time onward, it is judged that the display is not necessary because it has already been displayed (N in step 102), and the display changeover switch 16
If there is no change (N in step 114), step 1
The contents displayed in 08 or 112 are continuously displayed.

If there is a change in the display changeover switch 16 (Y in step 114), it has already been displayed (Y in step 116), and the process advances to the next step, and the change is caused by the changeover of the display changeover switch 16 from OFF to ON. And whether it is currently on (Y in step 118), or whether it is due to switching from on to off and currently off (N at step 118), and is due to change in switching from off to on. If so (Y in step 118), the area display is erased (step 122), the corresponding physical address is read from the storage area RAM2 (step 124), and displayed (step 126).

If the change is from on to off (N in step 118), the display of the physical address is erased (step 130), and based on the physical address of the storage area RAM2, the comparison table of the storage area ROM2 is displayed. The management number is read (step 132) and displayed (step 134).

In the above embodiment, it is also possible to provide a management number display section and a physical address display section without providing the display change-over switch 16 and display both the management number and the physical address. is there.

[0021]

As described above, according to the present invention, the fire receiver is provided with the display changeover switch so that the control number of the terminal and the physical address of the terminal can be changed over and displayed. Instead of setting up, the terminal management number and the physical address of the terminal are displayed together, so the troublesome work of reading the physical address of the terminal from the reference table when performing maintenance of the terminal is not required. ,
This has the effect of reducing maintenance work time and improving work efficiency.
