BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing a configuration of a fire alarm system 1 including a fire receiver 2 of the present invention. The fire alarm system 1 includes a fire receiver 2, a fire detector 3 connected to the fire receiver 2 and local lines L (L 1, L 2, L 3) and C, and a terminating resistor 4. FIG. 1 shows three district lines.
[0015]
The fire receiver 2 is installed in a disaster prevention center of a building, a management room of an apartment house, or the like, and monitors the entire fire alarm system 1. Although the present embodiment will be described with respect to an example implemented for a P-type receiver, it can also be implemented for an R-type fire receiver having a district window.
[0016]
The fire receiver 2 includes a CPU 11, a ROM 12, a RAM 13, an interface 14 to which a local line is connected, a display unit 15 for displaying various alarms and conditions, an operation unit 16 for executing various operations, and a sound unit 17 for emitting an alarm sound. Consists of
[0017]
The ROM 12 stores various control programs and control data for operating the fire receiver 2, the RAM 13 temporarily stores data and the like, and the CPU 11 stores the control programs and control data in the ROM 12. Therefore, the fire receiver 2 is controlled while using the RAM 13 as a work area.
The detailed description of the display unit 15, the operation unit 16, and the sound unit 17 will be described later.
[0018]
In a district line constituting one district, a plurality of fire detectors 3 are connected in parallel to a common line C and lines L1 (L2, L3). The common line C and the line L1 (L2, L3) are connected to the fire receiver 2 via the interface 14, and a fire signal from the fire detector 3 is transmitted via the line L1 (L2, L3). 2 is output. Further, a terminating resistor 4 for disconnection detection is connected to the terminating ends of the local lines L and C.
[0019]
FIG. 2 is a diagram showing a front view of the fire receiver 2.
The fire receiver 2 is provided with district windows 21, 21... For each district, one district indicator light 22 is provided on each district window 21, and the fire receiver 2 is connected to a terminal device connected to each district line. When a fire signal is input to the area 2, the area indicator light 22 is turned on to notify the occurrence of a fire in that area. In FIG. 2, 20 district windows 21, 21,... Are shown. Each of the district windows 21 is provided with a floor plate 23 indicating the name of the district, such as "1st floor showroom" or "room 201".
[0020]
Further, the district indicator light 22 lights or flashes when the maintenance mode is set, and changes the display mode when the test of the corresponding district line is completed. As a method of changing the display mode, if the district indicator is blinking during maintenance and inspection, the indicator is turned off after the end, and the display color is changed.
[0021]
In addition, the fire receiver 2 is provided with a plurality of display lamp groups 31 for displaying operation states of various functions and an alarm buzzer section 32 for generating an alarm sound.
The indicator light group 31 includes a fire representative light, a power light, a switch warning light, an acoustic stop light, and the like. The alarm buzzer section 32 emits an alarm sound when the fire detector 3 in any of the districts detects a fire.
[0022]
In addition, the fire receiver 2 is provided with a switch group 41 and a district line selection switch 42 for performing various operations.
The switch group 41 includes a sound stop switch, a test switch, a recovery switch, and the like. The district line selection switch 42 is a rotary switch used, for example, when selecting a district line to be tested during maintenance and inspection.
[0023]
In addition, a maintenance switch (not shown) is provided inside the fire receiver 2 to shift the mode to the maintenance and inspection mode and to return to the normal monitoring state from the maintenance and inspection mode. The reason why the maintenance switch is provided inside the fire receiver 2 is to prevent careless operations other than maintenance and inspection.
[0024]
That is, the area indicator light 21 and the indicator light group 31 are the display unit 15, the switch group 41, the rotary switch 42, and the maintenance switch are the operation unit 16, and the alarm buzzer unit 32 is the sound unit 17.
[0025]
Various processes in the fire detector 20 in the maintenance and inspection mode will be described based on a flowchart of the processing in the maintenance and inspection mode shown in FIG.
First, this processing starts from the normal monitoring processing, and it is determined in step S1 whether or not the maintenance inspection mode has been set. In step S1, if it is determined that the maintenance switch (not shown) has been turned on to enter the maintenance inspection mode, the process proceeds to step S2, and the determination in step S1 is repeated as long as it is not necessary.
[0026]
In step S2, it is determined whether or not an unmaintained inspection area line exists at the time of the previous maintenance and inspection. If it is determined that the district line counter is 0 and there is no unmaintained inspection district line, the process proceeds to step S3, where the district indicator lamps 22 corresponding to all the set district lines are blinked, Is set, and the process proceeds to step S5.
If it is determined that the area line counter is not 0 and there is an unmaintained inspection area line, the process proceeds to step S4, where the unmaintained inspection area line data in the buffer of the RAM 13 is read, and the area indicator light 22 of the corresponding area line flashes. Then, a district line counter for the corresponding district line is set, and the routine goes to step S5.
[0027]
In step S5, a process is performed to determine whether the maintenance and inspection mode has been released. If the maintenance and inspection mode has not been released, the process proceeds to step S6. In step S6, it is determined whether or not the maintenance inspection test for a certain area line has been executed (is completed). If it is determined that the execution has been performed, the process proceeds to step S7.
[0028]
In step S7, a process is performed to determine whether or not the tested local line has already been tested. If it is determined that the test has not been completed, the process proceeds to step S8.
In step S8, the district indicator corresponding to the district line for which the test has been completed is turned off, the termination processing for decrementing the district line counter is performed, and the process returns to step S5, where another district line is selected by the district line selection switch 42. The determinations in step S5 and step S6 are repeated until the test is executed.
If it is determined in step S7 that the test has been completed, the process returns to step S5, and the determination in steps S5 and S6 is repeated in the same manner.
[0029]
If it is determined in step S5 that the maintenance switch has been turned off and the maintenance inspection mode has been released, the process proceeds to step S9. In step S9, when the maintenance mode is canceled, it is determined whether or not the unmaintained area circuit remains, and it is determined that the area line counter is not 0 and the unmaintained area circuit remains. For example, the process proceeds to step S10, where the process of writing the data of the unmaintained inspection area line to the buffer of the RAM 13 is performed, the test is terminated, and the process returns to the normal monitoring process. In step S9, if it is determined that the area circuit counter is 0 and no untested area circuit remains, test end processing is performed and the processing returns to the normal monitoring processing.
[0030]
That is, when the fire receiver enters the maintenance / inspection mode, if there is no unmaintained / inspection area line, all the area indicator lights are turned on or flashed. Then, a test is performed for each area line, and the area indicator corresponding to the area line for which the test has been completed is turned off.
[0031]
Therefore, at the time of maintenance, all the district indicator lights are turned on or flashing, so that it is clear that maintenance is being performed. In addition, since the display form of the district indicator light is changed from lit or blinking to off for the district line for which maintenance and inspection has been completed, the district line for which maintenance has been completed and the district line for which maintenance has not been performed can be easily identified.
[0032]
Also, if the maintenance / inspection mode is terminated in a state where an unmaintained inspection area line is present, data relating to the unmaintained / inspection area line is written to the buffer of the RAM 13 and data is read from the buffer when the mode is switched to the maintenance / inspection mode again. If an unmaintained inspection area line exists, the area line 22 corresponding to the area line is blinked to indicate the area line for which maintenance and inspection has not been performed. You can collectively check the area lines that were not affected.
[0033]
【The invention's effect】
According to the first or second aspect of the present invention, it is possible to easily identify a maintenance-checked district line and a non-maintenance check district line based on the display state of the district indicator light, and there are a plurality of non-maintenance check district lines. In such cases, they can be checked all at once. Further, since the display state of the district indicator light changes at the end of the maintenance and inspection, it is possible to easily confirm the district line on which the test was performed.
[0034]
According to the third aspect of the present invention, even when the maintenance and inspection are stopped halfway, by reentering the maintenance and inspection mode, it is possible to grasp that there is a district line for which the maintenance and inspection has not been completed, and to perform the maintenance and inspection in the middle. Even if it ends, the work can be continued.
[0035]
According to the fourth aspect of the present invention, when the maintenance and inspection mode is set, it is easy to grasp that all the area lines are to be subjected to maintenance and inspection.
