Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an abnormality detection system capable of detecting an abnormal situation that has occurred in a room occupant and informing an outdoor person of the situation.

[0002]

2. Description of the Related Art Conventionally, when an elderly person or an unhealthy person is alone in a closed room such as a bathroom, if a physical abnormality or the like occurs, an alarm is provided by the person entering the room. There has been a simple alarm system that notifies an abnormal situation to a person living outside the room by operating a switch.

[0003]

However, with the above-mentioned conventional alarm system alone, if the occupant cannot leave the room by himself due to an abnormal situation and cannot move in the room, the alarm system cannot be operated, and the outdoor system cannot be operated. There is a possibility that the situation may worsen without being able to inform the cohabitants etc. of the abnormal situation. An object of the present invention is to solve the above-described problems, and to notify an abnormal situation to a roommate outside the room even if an abnormal situation such as a physical abnormality occurs in the room and the person cannot move in the room. An object of the present invention is to provide an abnormality detection device and an abnormality detection system that can ensure the safety of a room occupant.

[0004]

A first feature of the present invention relating to an abnormality detecting device for achieving this object is as described in claim 1 of the claims. A motion sensor that can detect motion and send a motion detection signal,
Alarm control means for receiving the moving object detection signal from the moving object sensor, starting a predetermined alarm control, transmitting an alarm generation command signal after the transmission of the moving object detection signal is interrupted for a predetermined time, and the alarm generation command signal And a reset switch capable of terminating the alarm control in order to deactivate the transmission function of the above.

According to a second feature configuration, as described in claim 2 of the claims, in addition to the first feature configuration, the alarm control means controls the alarm generation command signal to a predetermined value. The point is that the transmission of the second alarm generation command signal is started when the transmission is continued for more than the time.

A third feature of the present invention relating to the abnormality detection system for achieving this object is, in addition to the first feature described above, as described in claim 3 of the claims. Alarm means for receiving the alarm generation command signal from the alarm control means provided in the first characteristic configuration and generating an alarm.

According to a fourth aspect of the present invention, as described in claim 4 of the claims, in addition to the above-mentioned second aspect, the alarm control provided in the second aspect is provided. Alarm means for receiving the alarm generation command signal from the means and generating an alarm, and second alarm means for receiving the second alarm generation command signal from the alarm control means and generating an alarm. The second warning means is provided at a different place from the warning means.

According to a fifth feature of the present invention, in addition to the third or fourth feature of the invention, a lighting switch for turning on / off the indoor lighting is provided as described in claim 5 of the claims. The point is that the reset switch operates in conjunction with the OFF operation.

According to a sixth aspect of the present invention, in addition to the fifth aspect, the moving object sensor is linked to the on / off state of the lighting switch as described in claim 6 of the claims. Alternatively, at least one of the power sources of the alarm control means is turned on and off.

The operation will be described below. According to the first characteristic configuration, when an occupant enters the room, the movement is detected by the moving body sensor, the presence of the occupant is confirmed, and a predetermined alarm control is started. Once started,
Monitoring the presence or absence of a moving object detection signal transmitted by the moving object sensor, after the transmission of the moving object detection signal is interrupted, starts timekeeping, and receives the moving object detection signal before the interruption time reaches a predetermined time, The timer is reset after the end of the timekeeping, and if the transmission of the moving object detection signal is interrupted again, the timekeeping is restarted. An alarm device capable of receiving a signal emits, for example, an alarm sound, and by hearing the alarm sound by a third party, since the resident stays in the room for a predetermined time or more,
The above-mentioned occupant senses that the occupant is in a state where he / she cannot move and is unable to seek rescue due to some abnormal situation, and the occupant can be rescued, and the occupant can be safe. It is. By the way, since the moving body sensor originally detects a moving body and does not actively detect a stationary state, the moving person may leave the room and not detect the moving body, or may be in a truly stationary state and move the moving body. Since it is not known whether or not the alarm is detected, there is a possibility that the alarm generation command signal is transmitted when the occupant leaves the room. Calls can be prevented. Even if the reset switch is operated, the alarm control is only forcibly terminated, and the moving object sensor and the alarm control means are not turned off. The alarm control can be started again by the detection by the moving body sensor. As a result, by providing the reset switch, the moving body sensor can be positively used as a stationary sensor, the reliability of the abnormality detection device can be increased, and it can be put to practical use with a simple configuration. The alarm device capable of receiving the alarm generation command signal may simply generate an alarm sound as described above, may generate an alarm message or an alarm light, or may be an independent alarm device. Alternatively, an existing home security system or the like may be used.

According to the second characteristic configuration, even if the alarm generation command signal is continuously transmitted for a predetermined time or more, the transmission function of the alarm generation command signal is not deactivated by the reset switch. The transmission is not stopped, it is determined that the abnormal situation in the room has not been detected by a third party, another alarm can be generated, and the probability that the abnormal situation is detected can be increased, The reliability of the abnormality detection system can be improved. Here, even if the same alarm device that receives the alarm generation command signal receives the second alarm generation command signal and generates another alarm, the another alarm device generates the second alarm generation signal. Even if the command signal is received and generated, any function can be expected as long as it complements the warning generated by receiving the warning command signal.

According to the third characteristic configuration, the alarm means receives the alarm generation command signal transmitted from the abnormality detecting device according to the first characteristic configuration, and generates an alarm such as an alarm sound. An abnormal situation can be notified to a third party near the alarm means.

[0013] According to the fourth aspect, even if the alarm means of the third aspect is not able to notify a third party of an abnormal situation, the alarm means is located in a different place from the alarm means. A second alarm unit configured to output the second alarm generation command signal transmitted from the abnormality detection device having the second characteristic configuration to the second alarm unit.
By receiving the alarm means and generating an alarm such as an alarm sound, it is possible to make a third party in the vicinity of the second alarm means aware of an abnormal situation, and as a result, As a result, the accuracy of detecting an abnormal situation increases, and the reliability of the abnormality detection system can be improved.

According to the fifth characteristic configuration, an on / off state of the lighting device by the lighting switch is taken out at an arbitrary position between the lighting switch and the lighting device, and the resetting is performed in conjunction with the off operation. By activating the switch, the intended function can be exerted without necessarily providing the operation unit of the reset switch by the occupant at a position operable by the occupant, and the first or second feature described above. The degree of freedom in designing the abnormality detection device by the configuration is improved, the cost of the device can be reduced, and the work for installing the device can be simplified.

According to the sixth characteristic configuration, when the indoor lighting device is in the off state, at least one of the moving object sensor and the alarm control means is turned off, and the intended function is not exhibited. When the room is turned off and not in use, the moving body sensor detects movement of a person other than a person for some reason and starts the alarm control, and thereafter the cause disappears and an alarm can be prevented from being erroneously generated. The reliability of the detection system can be improved. Specifically, when the moving object sensor is turned off in the off state of the lighting device,
When the alarm control is not started and the alarm control unit is turned off in the off state of the lighting device, the alarm control unit does not transmit the alarm generation command signal regardless of the moving object detection signal. It is. Further, when the alarm control unit is turned off in the off state of the lighting device, the alarm control unit is turned off, so that the function of transmitting the alarm generation command signal is naturally inactivated, and the alarm control is also forcibly performed. It ends in.
