The timer 8 counts the time during reception of the first abnormal signal, and outputs a time-up signal after a predetermined time has elapsed. When the reception of the first abnormal signal is interrupted, the time count is reset.

When the CPU (central processing unit) 9 receives the first abnormal signal, it outputs a start signal to the timer 8 and starts the time counting of the timer 8. The start signal is output while receiving the first abnormal signal. When the reception of the first abnormal signal is interrupted or lost, a reset signal is output to the timer 8 and the timer 8 is reset.
Reset and stop. Further, when the first abnormal signal is continuously received for the above-mentioned predetermined time and the time-up signal is received from the timer 8, an alarm signal is output to the surrounding circuit means to perform various alarm processing such as an alarm notification. Do. Also,
When the second abnormal signal is received, regardless of the operation of the timer 8, an alarm signal is immediately output to perform various alarm processing.

As the means of the alarm processing, there are, for example, an alarm indicator 10, an acoustic circuit 11, an external device control circuit 13, and a notification output circuit 14 described below.

The alarm indicator 10 receives the alarm signal and displays an alarm state by blinking the lamp. Sound circuit 11
Receives an alarm signal and emits an alarm sound. The keyboard 12 is used for inputting data necessary for an alarming process and the like, and for processing an alarm display screen (not shown).

The notification output circuit 14 connects an automatic notification device or another receiver for notifying an alarm to the outside via a telephone line, for example, and transfers a notification signal to an external device (not shown).

Further, in the present apparatus, the signal transmission / reception circuits 6 and 7 enable the transmission / reception circuits 6 and 7 to transmit and receive signals between the detection device main body 1a and the receiver 1b in case a plurality of detection device main bodies 1a and ordinary sensors are connected. Has become. For example, a different unique address is assigned to each detection device main body 1a,
An address signal is output from the receiver 1b to each of the detection device main bodies 1a in a time-division manner to poll each of the detection device main bodies 1a and receive the own address signal.
Can output a signal indicating the detection state and return it to the receiver 1b.

Next, the operation of the abnormality detecting device 1 will be described. First, as shown in FIG. 3, when a person is present in a room A in which the detection device main body 1a is installed, when the photoelectric smoke sensor 3 detects smoke of a certain concentration or higher, the human body sensor 2 also detects the presence of a person. Therefore, the CPU 4 determines that both the photoelectric smoke sensor 3 and the human body sensor 2 are in the detection state, and outputs a first abnormal signal to the acoustic device 5 and the receiver 1b. The sound device 5 receives the first abnormal signal and sounds a notification sound to call attention to a person in the room A. Also,
When the receiver 1b receives the first abnormal signal, the timer 8 starts time counting.

Here, in the case of an abnormal state such as a lot of smoke in the room A, the person in the room A notices the notification sound and opens a window or performs an appropriate process such as initial fire elimination. Since the smoke sensor 3 is no longer in the detection state, the first abnormal signal disappears before the timer 8 of the receiver 1b times out, and the timer 8 of the receiver 1b is reset. The alarm indicator lamp 10 stops blinking, and the sound device 5 stops sounding the notification sound.
The same operation as described above is performed even when a temporary false alarm of the photoelectric smoke sensor 3 occurs.

Next, if there is no person in the room A in which the main body 1a of the detection device is installed, or if there is a person lying down or sleeping and cannot respond to the notification sound, the photoelectric smoke Even if the sensor 3 detects smoke of a certain concentration or more, the human body sensor 2 cannot detect the presence of a person because no change in the human body radiation infrared ray occurs in a state where no person is present or in a state where the person does not move. It determines that only the smoke sensor 3 is in the detection state, and outputs a second abnormal signal to the acoustic device 5 and the receiver 1b. The sound device 5 receives the second abnormal signal and emits a notification sound. Also, the receiver 1b
Receives the second abnormal signal and immediately issues an alert, and the person in the room B who notices the alert can rush to the room A and perform an appropriate process.

In the abnormality detecting device 1, as described above, the first or second abnormality signal is generated based on the presence or absence of the detection by the human body sensor 2, and appropriate abnormality processing can be performed. That is, when there is a person who can deal with the abnormality in the room A where the abnormality has occurred, the photoelectric smoke sensor 3 serving as the abnormality detection sensor detects the abnormality of the smoke, and the CPU 4 generates the first abnormality signal. Immediate alerts and lamps can alert the people in the area, and appropriate measures such as opening windows and clearing out early fires can be taken before abnormal conditions become too late. In addition, the person in the room B where the receiver 1b is installed can take a timer if the person in the room A in the abnormal state takes appropriate measures or the abnormal state is resolved within a predetermined time due to a temporary false alarm or the like. 8 is reset and the receiver 1b does not issue an alarm, so that it is not necessary to go to the room A where the abnormal state has occurred, so that efficient monitoring can be performed.

If the abnormal condition is not resolved within a predetermined time, the person in the room B rushes to the room A where the abnormal condition has occurred before the abnormal condition becomes severe and it is not too late to perform an appropriate process. You can do it.

Further, even if the CPU 4 generates the second abnormal signal because there is no person who can deal with the abnormality in the room A where the abnormal state has occurred, the person who notices the alarming process of the receiver 1b. Can immediately go to room A and take appropriate measures before the abnormal condition becomes severe and it is too late.

Also, because a person in room A is sleeping,
Even when the CPU 4 generates the second abnormal signal, the sound device 5 immediately emits a notification sound when the photoelectric smoke sensor 3 serving as the abnormal detection sensor detects the abnormality of the smoke. There are also effects such as enabling appropriate treatment. Note that the human body sensor 2 of the present embodiment is of a type that detects a change in radiated infrared rays of the human body, which occurs when a person moves as described above, detects the presence of the human body, and outputs a detection signal. In some cases, it may be difficult to detect a person with little movement, such as a falling person or a sleeping person, depending on the sensitivity, etc. If the sensitive human body sensor 2 that can be reliably detected is used, the CPU 4 generates a first abnormal signal, and performs the above-described processing when the first abnormal signal is generated.

In this embodiment, the abnormality detection sensor is the photoelectric smoke sensor 3, but for example, as shown in FIG. 4, a C sensor for detecting carbon monoxide gas which is a harmful gas to the human body.
The sensor may be an O sensor 3a, a sensor for detecting various fire factors such as a heat sensor or a flame sensor, or a sensor for detecting harmful gases other than carbon monoxide gas.
In these cases, the other configurations, operations, and the effects corresponding thereto are the same as those of the present embodiment (FIGS. 1 to 3).

The timer 8 does not need to have a time lag between the operation of the audio device 5 and the notification of the receiver 1a, and the human body sensor 2 can emit the signal of the receiver 1b at the same time as the audio device 5. May be displayed on the receiver 1b. In that case, the person who has seen the information on the presence or absence of the person on the receiver 1b can rush to room A as necessary.

Further, the timer 8 is provided on the main body 1a of the detecting device, and when the first abnormal signal is generated, the timer 8 is started and the first abnormal signal is not output to the receiver 1b. Outputs a second abnormal signal to the receiver 1b when the timer 8 has timed out for a predetermined time,
You may make it the receiver 1b perform an immediate alert process with respect to this 2nd abnormal signal.

When the second abnormal signal is generated, the person in the room B notices the alarm and there is almost no time difference because, for example, the detection device main body 1a and the receiver 1b are installed close to each other. In a case where it is possible to rush to the room A, the sound may be emitted only from the receiver 1b without the sound device 5 being sounded. Further, the human body sensor 2, the photoelectric smoke detector 3, the CPU 4, the sound device 5,
And the like need not be provided integrally. In addition, human body detection sensors,
The abnormality detection sensor, the processing unit, the notifying unit, and the like are not limited to those in the above embodiment as long as the effects of the present application can be achieved.
