  Here, as shown in FIG. 2, a plurality of infrared sensors 2 are provided in the toilet, for example, near the floor so as to face the plurality of infrared projectors 7, and when the person P enters the toilet, infrared rays from the infrared projector 7 are provided. Is detected by the person's P foot or the like and the amount of received infrared light is reduced, so that the presence of the person P is detected and sent to the controller 6, and the pyroelectric sensor 3 is installed in the toilet as shown in FIG. For example, provided on the ceiling, when the person P enters the toilet, the movement of the person P is detected by a change in infrared rays from the person P and sent to the controller.

  Further, as shown in FIG. 2, the microphone 4 is provided, for example, together with the speaker 5 on the sink 8 in the toilet, for example, and inputs the voice uttered by the person P in the toilet, The signal is converted into a signal and sent to the controller 6. The speaker 5 receives an electrical signal corresponding to the voice that asks the person P to utter and act, and outputs based on information stored in the memory or the like in advance by the controller 6. The signal is converted into a voice, and a voice that asks the person P for voice and action is output.

  The controller 6 is composed of, for example, a normal microcomputer and is housed in, for example, a case 9 for housing a speaker 5 on the sink 8 in the toilet, for example, as shown in FIG. The sensor 2, the pyroelectric sensor 3, the microphone 4 and the speaker 5 are connected, and as shown in FIG. 1, for example, connected to a transmitter 10 housed together in the case 9, and further, for example, from a commercial power supply Is connected to a power supply circuit (not shown).

  The transmitter 10 includes, for example, a receiver 11 that receives a radio signal from another security sensor (not shown) such as an open / close sensor that detects opening / closing of a window or a door and notifies the fact by radio waves, and the receiver is connected to the security sensor. The controller 6 outputs to the receiver 11 of the other security system 13 including the wireless telephone 12 for notifying a fixed telephone, a mobile telephone or the like via a wireless telephone line when the radio signal is received. The emergency situation occurrence signal described later is transmitted wirelessly, and the emergency situation occurrence signal received by the receiver 11 is fixed by the radio telephone 12 via the radio telephone line as in the case of receiving the radio signal from the security sensor. Report to phone or mobile phone.

  In the closed emergency detection system 1 of this embodiment, the controller 6 operates according to the procedure shown in FIG. 3 based on a program given in advance. That is, here, first, in step S1, whether or not the person P exists in the toilet is detected by the infrared sensor 2, and if it is determined from the output signal of the infrared sensor 2 that the person P does not exist in the toilet, step From S2, the process returns to step S1. On the other hand, if it is determined from the output signal of the infrared sensor 2 that the person P is present in the toilet, the process proceeds from step S2 to step S3.

  In step S3, the pyroelectric sensor 3 detects whether or not the person P is moving in the toilet, and if it is determined from the output signal of the pyroelectric sensor 3 that the person P in the toilet is moving, step S4. From step S4, if it is determined from the output signal of the pyroelectric sensor 3 that the person P in the toilet is not moving, the process proceeds from step S4 to step S5. In step S5, the person P exists and Since the person P has not moved, it is determined by a software timer in the controller 6 whether or not a predetermined time has elapsed since the first time in step S5, and a predetermined time such as 1 minute set in advance has elapsed. If not, the process returns to step S1 and repeats the above detection. On the other hand, if the predetermined time has passed with the person P present and no movement, there is a possibility of an emergency situation. Since proceeds from step S5 to step S6.

  In step S6, the controller 6 outputs a voice requesting voice and action to the person P through the speaker 5, and in the subsequent step S7, when the person P in the toilet generates a voice through the microphone 4, the voice is heard. And the pyroelectric sensor 3 detects whether the person P is moving in the toilet.

  Next, in step S8, a software timer in the controller 6 determines whether or not a predetermined time and another predetermined time have passed since the output of the voice for requesting the utterance and action to the person P in step S6. If the set predetermined time such as 10 seconds has not elapsed, the process returns to step S7 to repeat the voice input and detection, while the microphone 4 inputs the voice of the person P in the toilet and the pyroelectric sensor 3 If the predetermined time has passed while detecting whether or not the person P is moving in the toilet, the process proceeds from step S8 to step S9.

  In step S9, it is determined whether or not there is an input of the voice uttered by the person P or the movement of the person P, and there is an input of the voice uttered by the person P or the movement of the person P. In that case, it is determined that no emergency has occurred in the person P, and the process returns to step S1. Note that whether or not a voice uttered by the person P has been input can be determined, for example, by detecting a sound in a frequency band corresponding to the voice of the person through a bandpass filter. On the other hand, if there is no input of the voice uttered by the person P and no movement of the person P, it is determined that an emergency situation has occurred and the process proceeds to step S10, and the transmitter 10 is notified that the emergency situation has occurred.
