Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a monitoring control system for monitoring and controlling a fire, for example, a storage type receiver, and a status display control method.

[0002]

2. Description of the Related Art Conventionally, a system having a configuration as shown in FIG. 10 is known as a disaster prevention system. Referring to FIG. 10, this disaster prevention system includes a receiver 51 and a receiver 5.
1. Control terminals (sensors) 2a, 2 monitored and controlled by
b,... and controlled terminals (shutters, fire doors, etc.) 3a, 3
b,...

Here, a receiver 51 and control terminals 2a, 2
are connected to the controlled terminals 3a, 3b,... by, for example, a predetermined transmission line (line or wireless).

As such a disaster prevention system, a sensor is used.
(For example, fire detectors) 2a, 2b,..., When analog detectors are used, as the receiver 51, the output level from the analog detectors (for example, when the analog detectors are smoke detectors). The smoke density level), for example, by address polling, based on the output level of the analog type sensor that has been taken, judge abnormalities such as fire and gas leaks, and perform an alarm or display to that effect. Predetermined controlled terminal (for example, smoke prevention terminal)
May be configured to perform the interlocking control on the.

[0005] In such a disaster prevention system, in order to perform an alarm or display of an abnormality such as a fire or a gas leak as described above, or to perform an interlocking control, a single analog sensor is provided inside the receiver 51. It is possible to set a plurality of (multi-stage) thresholds for the output level of.

Specifically, as shown in FIG. 11, a plurality of thresholds are set for the output level from one sensor (or for the smoke density level when the sensor is a smoke sensor). For example, the threshold value TH _{1 of} the alert level, the abnormal alert level
(E.g. fire report level) threshold TH _2, and has become capable of setting a threshold value TH ₃ interlocking paper level. Here, the threshold value TH ₁ of warning levels are not lead to is determined that abnormality such as a fire or gas leak, levels that may be determined that the abnormality such as a fire or gas leak (warning level) Is used to determine whether the output level of the analog sensor has been reached. The threshold TH ₂ abnormality report level is used to determine the level that is determined to be abnormal such as a fire or gas leak the output level of the analog sensor has reached. The threshold TH ₃ interlocking paper level, the output level of the analog sensor has exceeded the level of abnormality such as a fire or gas leak, further, it is determined that it is necessary to interlock control a predetermined controlled device It used to determine reached level, when the output level of the analog sensor has reached the threshold TH ₃ interlocking paper level, as interlocking control operation is performed for a given a controlled terminal Has become.

By the way, when the receiver 51 outputs an abnormal alarm (for example, a fire alarm) when the output level of the analog sensor reaches a threshold value TH ₂ of an abnormal alarm level (for example, a fire alarm level), This can be a false alarm. FIG. 12 is a diagram for explaining this situation.
In the example of FIG. 12, one certain analog sensor, for example after the output level L of 2a has reached the threshold TH ₂ abnormality report level, when immediately drop abnormality report level threshold TH ₂ The following is shown and, in this case, when the output level of the analog sensor has reached the threshold TH ₂ abnormality report level (fire report level), and outputs an abnormality warning as shown (fire alarm), the anomaly alarm It is a misinformation. That is, in such a case, it should not be determined that there is an abnormality such as a fire or gas leak, and no abnormality alarm should be output.

[0008] To avoid the occurrence of such false alarms, the receiver 51, after the output level of the analog sensor has reached the threshold TH ₂ abnormality report level, which is abnormal report level continuously for a predetermined time period when determining whether a state exceeding the threshold value TH _2, in a state where the output level of the analog sensor has exceeded the threshold value TH ₂ of a predetermined time period continues to be abnormal paper level, alarming abnormality (e.g. fire alarm) A so-called accumulator-type receiver that outputs a signal can be used.

FIGS. 13 (a) and 13 (b) are diagrams for explaining the function of such a storage type receiver. In the accumulation-type receiver, generally, you can set the predetermined time duration after the threshold is reached TH ₂ of the output level abnormality report level (eg fire report level) of analog sensor as storage period T _1, the accumulating period T _{when one} is set, after the output level of the analog sensor has reached the threshold TH ₂ abnormality report level, among the storage period T _1, the threshold power level is abnormal report levels of analog sensor determines whether beyond continued TH _2, in the accumulating period T _1, a condition that the output level of continuing to analog sensor exceeds the threshold value TH ₂ abnormality report level, the accumulating period T Upon completion of step ₁ , it is determined that there is an abnormality (for example, a fire or gas leak), and an abnormality alarm (for example, a fire alarm) is output. Therefore, in the case as shown in FIG. 13 (a), it is not determined that there is an abnormality (for example, a fire), and it is not necessary to generate a false report. Only in the case of FIG.
(E.g., fire or gas leak) and output an abnormal alarm (e.g., fire alarm).

FIG. 14 is a diagram showing a configuration example of a conventional display unit (display panel) provided in such a storage type receiver. In the example of FIG. 14, the display unit 52 of the storage-type receiver includes:
An abnormal light (for example, a fire light) 30 and a first report sensor display portion 31
-1 and a follow-on sensor display portion 31-2 and a light during accumulation
(Representative light) 34.

In the following, for convenience of explanation, it is assumed that the control terminals (sensors) 2a, 2b,... Of this system are of the same type and type, and that the environment used is the same. , Thus, in the example sensor 2a and sensor 2b, the threshold value TH _1, TH _2, TH ₃ are respectively set to the same value, also the accumulation period is set to the same thing, respectively.

Here, the abnormal light (for example, a fire light) 30 is turned on when it is determined that any of the sensors of this system is abnormal (for example, a fire) after the lapse of the accumulation period.

Further, Hatsuho sensor display portion 31-1, in this system, information about the sensor output level has reached the first threshold value TH ₁ of warning level is provided to display the status , display 3 for displaying information for identifying the sensor output level has reached the first threshold value TH ₁ of warning level (e.g., district number of the sensor)
Warning lamp 32 and 2a, the output level of the sensor lights up when in the state exceeding the threshold value TH ₁ of warning level
and b, the output level of the sensor has an abnormality report lamp (e.g. a fire report lamp) 32c which lights when in a state exceeding the threshold value TH ₂ abnormality report level (eg fire report level).

Further, the following information detector display part 31-2 has:
In this system, the output level of information about the next reaches the detector to a threshold value TH ₁ of warning level is provided to display the status, output level then reaches the threshold TH ₁ for warning level Information to identify the sensor
Display 33 for displaying (for example, the district number of this sensor)
a and the output level of this sensor is a warning level threshold T
Warning lamp 33b to light up when a state exceeding the H ₁
When, and a this anomaly report lamp output level of the sensor is lit when a state exceeding the threshold value TH ₂ abnormality report level (eg fire report level) (e.g. a fire report lamp) 33c.

The storage lamp (representative lamp) 34 is designed to be turned on when any of the sensors in the system is in the storage period.

The above-described display control on the display unit 52 (the warning lamps 32b and 33b, the abnormality lamps 32c and 33).
The lighting control of c and the lighting control of the storing lamp 34 are performed by the control unit in the receiver 51 in a manner as shown in FIG.

That is, it is assumed that attention is paid to the warning light 32b and the abnormal light 32c of the initial sensor display portion 31-1, for example.
But if there is to be one that corresponds to a particular sensor, also accumulating period when T ₁ is assumed to be set to a predetermined one, the output level L is warning level from this particular sensor If it does not reach the threshold TH _1, the warning lamp 32b, abnormal paper lamp 32c are both in oFF state.

[0018] Then, the output level L from the particular sensor reaches the threshold TH ₁ of warning levels, warning lamp 32b is turned on. At this time, when the output level L from the particular sensor does not reach the threshold value TH ₂ abnormality report levels, abnormal paper lamp 32c is in the off state.

[0019] Then, the output level L from the particular sensor reaches the threshold TH ₂ abnormality report levels, abnormal paper lamp 32c is turned on. At this time, after the output level has reached the threshold TH ₂ abnormality report level, if not completed the accumulating period T ₁ (if it is during the storage period), accumulated during lamp 34 is turned on in , when completing the accumulation period T ₁ is accumulated in the lamp 34 is turned off, the abnormality lamp 30 is turned on.

As described above, in this storage type receiver, for example, the lighting of the abnormality notification lamp 32c and the lighting of the storage lamp 34 are performed by:
The operator knows that it is during the accumulation period T ₁ , and turns on the abnormal information light 32 c, turns off the accumulation lamp 34, and turns off the abnormal light 30.
In the lighting, the operator can know the completion of the accumulation period T _1.

[0021]

However, in such a conventional storage-type receiver, for example, the first-report sensor completes the storage period and is determined to be abnormal (for example, a fire). The follow-up detector is at the abnormal report level (fire report level)
If it exceeds the threshold value TH ₂ at the state during the accumulation period,
The display 52 displays an abnormal light (fire light) 3 as shown in FIG.
0 lights up, and the warning light 32b and the abnormality warning light (fire warning light) 32c of the first report sensor display section 31-1 are lit, and the warning report of the subsequent report sensor display section 31-2. The light 33b and the abnormal light (fire light) 33c are turned on, and the
(Representative light) 34 is turned on.

In this case, when the abnormal light (fire light) 30 is turned on, either the first report sensor or the subsequent report sensor becomes abnormal (fire).
It is found that the status is determined to be
By turning on the (representative light) 34, it can be seen that either the first report sensor or the subsequent report sensor is in a state during the accumulation period.
From this display alone, there is a drawback that it is not possible to determine which of the first report sensor and the subsequent report sensor is abnormal (fire) and which one is in the accumulation period.

According to the present invention, when one of the plurality of sensors is determined to be abnormal (for example, a fire) and one of the plurality of sensors is in a state during the accumulation period, which sensor is abnormal
(E.g., fire), it is possible to clearly understand which sensor is in the accumulation period, and in this case, the configuration of the display unit is compared to the conventional one. It is an object of the present invention to provide a monitoring control system, a storage type receiver and a status display control method which can be made smaller.

[0024]

In order to achieve the above object, according to the first, second, third, sixth, and eighth aspects of the present invention, the storage type receiver has an output level. A state relating to a certain analog sensor exceeding the abnormality report level can be displayed so that the analog sensor can be specified.
When a predetermined period is set as the accumulation period from the time when the output level of the analog sensor exceeds the abnormality report level, the one display unit includes:
When the output level of a certain analog sensor exceeds the abnormality report level during the accumulation period and when the accumulation period is completed, a display that can be distinguished from each other is made as a status display regarding the analog sensor. You. As a result, when one of the plurality of sensors is determined to be abnormal (for example, a fire) and one of the sensors is in the state during the accumulation period, which sensor is determined to be abnormal (for example, a fire) In this state, the operator can clearly know which sensor is in the state during the accumulation period.

Also, in this case, one display means can be provided with a function for clearly identifying whether or not the data is being stored. Thus, there is no need to separately provide a storage lamp, and the configuration of the display unit of the storage type receiver can be made smaller than in the past.

According to the fourth, fifth and seventh aspects of the present invention, a predetermined period from the time when the output level of the analog sensor exceeds the abnormal alarm level can be set as the first accumulation period. A storage type receiver which can set a predetermined period as a second storage period from the time when the output level of the analog sensor exceeds the warning level, wherein the output level of the storage type receiver is First display means capable of identifiably displaying the status of one analog sensor that has exceeded an abnormal alarm level, and one analog sensor whose output level has exceeded an alert level Second display means capable of displaying a state relating to the sensor so that the analog sensor can be specified; and wherein the first display means has an output level of the analog sensor indicating an abnormality report level. Beyond When the first accumulation period is during the accumulation period and when the first accumulation period is completed, a display that can be distinguished from each other is made as a status display relating to the analog sensor, and the second display means includes: When the output level of the analog sensor exceeds the warning level in the second accumulation period and when the second accumulation period is completed, the display that can be distinguished from each other is related to the analog sensor. This is performed as a status display. Thus, when both the first accumulation period and the second accumulation period are set, the first
The display means and the second display means can display a more detailed state, and the operator can grasp the state of the sensor in more detail.

In this case, both the first accumulation period and the second accumulation period can be set, or only the first accumulation period can be set, or only the second accumulation period can be set. If only the first accumulation period is set, or if only the second accumulation period is set, it is determined to be abnormal (to output an abnormality alarm).
Whether to start the accumulation period from the time when the output level reaches the threshold value of the abnormality report level or from the time when it reaches the threshold value of the alert level can be switched as needed.

According to the ninth aspect of the present invention, the start time of the accumulation period for judging an abnormality (for outputting an abnormality alarm) is determined when the output level of the sensor reaches the threshold value of the alert level. The processing can be performed from the beginning.

[0029]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing a configuration example of a monitoring control system according to the present invention. Referring to FIG. 1, the monitoring control system (for example, a disaster prevention system) includes a receiver 1,
A terminal group (control terminals (for example, fire detectors) 2a, 2b, ...) and controlled terminals (for example, shutters, fire doors, etc.) 3a, 3b, ... that are monitored and controlled by the receiver 1.

Here, the receiver 1 and the terminal group (the control terminal 2
a, 2b,..., controlled terminals 3a, 3b,...) are connected, for example, by a predetermined transmission path (line, wireless, or the like).

As such a monitoring and control system, when, for example, analog sensors are used for the sensors (for example, fire detectors) 2a, 2b,...
Similarly to the receiver 51 of the disaster prevention system of (1), the output level from the analog sensor (for example, if the analog sensor is a smoke sensor, the smoke density level) is acquired by, for example, address polling, and the acquired analog Based on the output level from the sensor, it judges abnormalities such as fires and gas leaks, and issues warnings and displays to that effect, and performs interlocking control for predetermined controlled terminals (for example, smoke prevention terminals). Can be performed.

In such a monitoring and control system (for example, a disaster prevention system), an alarm or display of an abnormality such as a fire or a gas leak as described above or interlocking control is performed. For the output level from one analog sensor, a plurality of (multi-stage) thresholds similar to those shown in FIG.
H ₁ , a threshold value of an abnormal information level (for example, a fire information level) TH ₂ ,
The threshold TH ₃ of the interlocking report level has to be set.

FIG. 2 is a diagram showing a specific example of this monitoring control system. Referring to FIG. 2, a receiver 1 of the monitoring and control system includes a C that controls the entire monitoring and control system.
, A PU 16, a ROM 16 in which a control program of the CPU 15 is stored, a RAM 17 used as a work area of the CPU 15, a display / operation unit 19, control terminals 2 a, 2 b,..., Controlled terminals 3 a, 3 b,. And an interface unit 18 functioning as an interface (for example, a transmission interface).

In FIG. 2, the display / operation unit 1 of the receiver 1
As 9, for example, display means such as a touch panel type liquid crystal display (LCD) or CRT display, and input means such as a keyboard and a mouse can be used.

By the way, in the present invention, in order to prevent the occurrence of false alarms, the receiver 1, after the output level of the analog sensor has reached the threshold TH ₂ abnormality report level,
It is determined whether a state exceeding the threshold value TH ₂ abnormality report level continuously for a predetermined period of time, in a state in which the output level exceeds the threshold value TH ₂ of a predetermined time period continues to be abnormal report level of the analog type sensor In such a case, a so-called storage-type receiver that outputs an abnormal alarm (for example, a fire alarm) is used.

That is, the receiver 1 of the present invention also
(a), when it reaches the threshold TH ₂ of (b) to have a function as a storage-type receiver, as shown, the output level of the analog type sensor abnormality report level (eg fire report level) To a predetermined period from the accumulation period (hereinafter referred to as the first accumulation period)
It can be set as T _1, when the first accumulation period T ₁ is set, after the output level of the analog sensor has reached the threshold TH ₂ abnormality report level, the first accumulation period T
In _1, the output level of the analog type sensor, it is determined whether or exceeds continuously the threshold TH ₂ abnormality report level, in the accumulating period T _1, continue to output level abnormality report levels of analog sensor on condition that exceeds the threshold value TH _2,
At the completion to the accumulation time T _1, it is determined that an abnormality (e.g. fire and gas leak, etc.), and outputs an abnormality warning (eg fire alarm). Therefore, in the case of FIG.
(E.g., fire or gas leak), no false alarm is required, and only in the case of FIG. 13 (b), an abnormality (e.g., fire or gas leak) is determined and an abnormal alarm (e.g., fire alarm) Can be output.

Further, in the present embodiment, the accumulation type receiver 1 is provided with a predetermined period from the point in time when the output level of the analog type sensor reaches a threshold value TH ₂ of an abnormal alarm level (for example, a fire alarm level). In addition to the function that can be set as _one accumulation period T ₁ , or a predetermined period from when the output level of the analog sensor reaches a threshold value TH ₂ of an abnormal alarm level (for example, a fire alarm level), the first accumulation period instead of configurable features as the period T _1, equipped with configurable features a predetermined time period from the time when the output level has reached the threshold TH ₁ for warning level of the analog type sensor as the second accumulation period T ₂ May be.

In FIG. 3, the accumulation type receiver 1 stores the first accumulation time for a predetermined period from the time when the output level of the analog type sensor reaches a threshold value TH ₂ of an abnormal alarm level (for example, a fire alarm level). In addition to the function that can be set as the period T _1, there is a function that can set a predetermined period as the second accumulation period T ₂ from the time when the output level of the analog sensor reaches the warning level threshold TH ₁ . Configuration example and when the first accumulation period T ₁ and the second accumulation period T ₂ and is shown. In this case, the first accumulation period T ₁ and the second accumulation period T ₂
Can be set independently of each other.

For example, when both the first accumulation period T ₁ and the second accumulation period T ₂ are set, the receiver 1 determines when the output level of the sensor reaches the warning level threshold TH _1. up to the second accumulation period T ₂ and in storage from, also be processed from the time when the output level of the sensor has reached the threshold TH ₂ abnormality report level to the first accumulation period T ₁ as in storage Can be. In this case, for example, the processing can be performed by giving priority to the first accumulation period T ₁ over the second accumulation period T ₂ , and even during the second accumulation period T ₂ , When T ₁ is completed, at which time, a condition that the output level of the first accumulation period T detector continuously in ₁ exceeds the threshold value TH ₂ abnormality report level, it is determined as abnormal,
An abnormal alarm is output. In this case, the second accumulation period T ₂ are, as described later, and controls the display of the warning lamp in greater detail, it is used to perform a status display detector in greater detail.

More specifically, for example, the first accumulation period T
₁ 20 seconds, to the second accumulation period T ₂ may be set to 20 seconds, or the first accumulation period T ₁ to 20 seconds,
The second accumulation period T ₂ may be set to 50 seconds.
However, at the time of actual control, when the first accumulation period T ₁ is passed, if the second accumulation period T ₂ is as ongoing, for example, as shown in FIG. 4, the first accumulation after the elapse of the period T _1, it is assumed that the second accumulation period T ₂ may be terminated.

Further, for example, it is also possible to set only the first accumulation period T ₁ and not set the second accumulation period T ₂ (set to “0”). In this case, the beginning of the accumulation period (for outputting an abnormality alarm) that for determining an abnormality, the output level of the detector can be from the time the threshold is reached TH ₂ abnormality report level . That is, in this case, the receiver 1 is adapted to perform the process from the time when the output level of the sensor has reached the threshold TH ₂ abnormality report level to the first accumulation period T ₁ as in storage . Specifically, from the time when the output level of the sensor has reached the threshold TH ₂ abnormality report level, the T ₁ first accumulation time and counting, in the accumulation period T ₁ of the first, the output level of the detector when exceeding the threshold value TH ₂ abnormality report levels continued, in the first time of the completion of the accumulation period T ₁ (time lapse), it is determined that an abnormality, and outputs an abnormality warning.

Further, only the second accumulation period T ₂ is set,
Not set first accumulation period T ₁ (set to "0") may be. In this case, the beginning of the accumulation period (for outputting an abnormality alarm) that for determining an abnormality, the output level of the detector can be from the time the threshold is reached TH ₁ of warning level . That is, in this case,
Receiver 1, the output level of the sensor is adapted to carry out the processing from the time the threshold is reached TH ₁ of warning level to a second accumulation period T ₂ as in storage. Specifically, from the time when the output level of the sensor has reached the threshold TH ₁ for warning level, the second accumulated counts a time T _2, in the second accumulation period T _2, sensor output level when but exceeding the threshold value TH ₁ of warning levels continued, the second accumulation period T ₂
Upon completion (elapsed time) of the above, it is determined that an abnormality has occurred, and an abnormality alarm is output.

As described above, according to the present invention, only one of the first accumulation period T ₁ and the second accumulation period T ₂ can be arbitrarily selected, and the concept (expression) of accumulation becomes necessary. It can be switched appropriately as needed.

Also, neither the first accumulation period T ₁ nor the second accumulation period T ₂ can be set (both are set to “0”).

FIG. 5 is a diagram showing an example of the configuration of the display / operation unit 19, particularly the display unit (display panel), provided in the storage type receiver 1 of the present invention. In the example of FIG.
(Especially the display unit) include an abnormal light (for example, a fire light) 20, an initial report sensor display portion 21-1, and a subsequent report sensor display portion 21-1.

In the following, for convenience of explanation, it is assumed that the control terminals (sensors) 2a, 2b,... Of this system are of the same type and type, and that the environment used is the same. , Thus, in the example sensor 2a and sensor 2b, the threshold value TH _1, TH _2, TH ₃ are respectively set to the same value, also the accumulation period is set to the same thing, respectively.

Here, the abnormal light (for example, a fire light) 20 is turned on when it is determined that any of the sensors of this system is abnormal (for example, a fire) after the lapse of the accumulation period.

[0048] Further, Hatsuho sensor display portion 21-1, in this system, information about the sensor output level has reached the first threshold value TH ₁ of warning level is provided to display the status , display 2 for displaying the information for identifying the sensor output level has reached the first threshold value TH ₁ of warning level (e.g., district number of the sensor)
2a and a warning lamp 22b that the output level of the sensor flashes or lights up when in the state exceeding the threshold value TH ₁ of warning level, the output level of the detector is abnormal report level (eg fire report level and a flashing or lighting an abnormal report lamp (e.g. a fire report lamp) 22c when in the state exceeding the threshold value TH ₂₎ of.

Further, the following information sensor display part 21-2 is
In this system, the output level of information about the next reaches the detector to a threshold value TH ₁ of warning level is provided to display the status, output level then reaches the threshold TH ₁ for warning level Information to identify the sensor
(For example, the area number of this sensor)
a and the output level of this sensor is a warning level threshold T
A warning lamp 23b flashing or lit when a state exceeding the H _1, or blinks when in the state in which the output level of the sensor exceeds the threshold value TH ₂ abnormality report level (eg fire report level) An abnormal light (for example, a fire light) 23c to be turned on is provided.

In this case, the above-described display control on the display unit 19 (that is, the warning lights 22b and 23b, the abnormal light 2
The blinking and lighting control of 2c and 23c are performed by the control unit in the receiver 1, that is, the CPU 15, in a manner as shown in FIG.

That is, it is assumed that attention is paid to the warning light 22b and the abnormal light 22c of the initial sensor display portion 21-1, for example.
Is assumed to correspond to a specific sensor, and both the first accumulation period T ₁ and the second accumulation period T ₂ are set to predetermined ones. The output level L from a specific sensor is equal to the warning level threshold TH.
_When the number has not reached ₁ , both the warning light 22b and the abnormal light 22c are in an extinguished state.

[0052] Then, the output level L from the particular sensor is when in the second during the accumulation period T ₂ reached the threshold value TH ₁ of warning level warning lamp 22b blinks.
At this time, the output level L from this specific sensor is
If the has not reached the threshold value TH ₂ abnormality report level,
Abnormal paper lamp 22c is in the off state, the output level L is first during the storage period T ₁ reaches the threshold value TH ₂ abnormality report levels, abnormal paper lamp 22c becomes blinking.

Next, when the second accumulation period T ₂ is completed, and when the second accumulation period T ₂ has elapsed, the output level from the specific sensor during the second accumulation period T _{2 is set.} when L was exceeded continuously threshold TH ₁ for warning level warning lamp 22b is turned on. At this time, when not yet the first accumulation period T ₁ is completed, the abnormality report lamp 22c is in the blinking state.

Next, the first accumulation period T ₁ is completed, and when the first accumulation period T ₁ has elapsed, the output level L from the specific sensor during the first accumulation period T _1. If the was over continuing the threshold TH ₂ abnormality report levels, abnormal paper lamp 22c is turned on. At this time, the abnormal lamp 20 is also turned on.

FIG. 7 is a diagram for explaining the monitoring result of the specific sensor represented by the extinguishing, blinking, and lighting states of the warning light 22b and the abnormal light 22c corresponding to the specific sensor. is there. Referring to FIG. 7, the warning light 22b,
When none of the abnormality lamps 22c is off, the output level of this specific sensor is equal to the warning level threshold TH.
_It has not reached ₁ , indicating that it is normal. Further, when the warning lamp 22b is in the blinking state represents that the output level of the particular sensor is in the second during the accumulation period T ₂ reached the threshold value TH ₁ of warning levels. When the warning light 22b is in the lighting state,
The output level of this particular sensor is the alert level threshold T
Among the H ₁ second accumulation period T _2, or exceeds continuously, or indicates that the second set of the accumulating period T ₂ is not. Further, when an abnormality report lamp 22c is in the blinking state represents that the output level of the particular sensor is in the first during the storage period ₁ reached the threshold value TH ₂ abnormality report level. Further, when an abnormality report lamp 22c is in the lighting state, in the accumulating period T ₁ output level is the threshold value TH ₁ abnormality report levels first for this particular sensor, or either exceeded continuously, the first accumulation it represents that it has not been set for the period T _1.

FIG. 8 shows a comparison between the state display control method of the abnormal lamp in the receiver of the present invention and the state display control method of the abnormal lamp and the storing lamp in the conventional receiver. Referring to FIG. 8, in the storage-type receiver 1 of the present invention, the output level of a specific sensor is set to a threshold value T of the abnormality report level

When the abnormality notification lamp 22c is turned on, it is possible to know the completion of the _first accumulation period T1.

[0057] In contrast, in the conventional accumulation type receiver, the output level of a specific sensor serving as the first accumulation period ₁ medium reached the threshold value TH ₂ abnormality report levels, abnormal paper lamp 32c
, Immediately turned on in, therefore, the operator, or by abnormal paper lamp 32c, which is the first in the accumulation period T _1, it is impossible to know whether the completed first accumulation period T _1. Therefore, conventionally, when the output level is first during the storage period T ₁ is to light accumulation during lamp 34 with lit abnormal paper lamp 32c, also completes the first accumulation period T _1, the abnormality Although the notification lamp 32c is turned on, the storage lamp 34 is turned off, and the operator is informed that the _first storage period T1 is being performed by turning on the abnormality notification lamp 32c and the storage lamp 34, Further, the operator is informed that the _first accumulation period T1 has been completed by turning on the abnormality notification lamp 32c and turning off the accumulation lamp 34.

However, as described above, in the conventional storage-type receiver, for example, the initial-report sensor is in a state where the accumulation period has ended and is determined to be abnormal (for example, a fire), and the subsequent-report sensor is determined to be abnormal. exceeds the threshold value TH ₂ abnormality report level (fire report level) but in any state during the accumulation period, as shown in FIG. 16, the abnormality report lamp Hatsuho sensor display portion 31-1
