[Industrial application]

 The present invention relates to an entrance / exit monitoring device for monitoring passage of a moving object such as a door / window of a house or an entrance / exit (import door) of an automatic transfer device of a processing / production factory.

[0002]

[Prior Art]

 2. Description of the Related Art Conventionally, various monitoring devices have been devised which are installed at entrances and exits, windows, etc. in order to monitor the exit and movement of elderly people and infants outside the house. For example, an infrared ray monitoring device for passing objects is placed at the entrance / exit, or a transmitter that emits radio waves is carried to the human body to be monitored, such as infants, and a device that receives this radio wave and issues an alarm sound There is a method to generate an alarm by a squelch signal generated in the FM receiver when a moving object with a device is far from the receiver. However, in the case of the infrared monitoring device, an alarm was issued every time all moving objects passed, and it was not possible to monitor a specific person. If a person to be monitored carries a transmitter with the transmitter removed from the body and placed in the vicinity of the receiver, no alarm will be issued, and the person can pass through or leave the room without being detected by the watcher. it can. It is also possible to sew on the kimono or clothes so that the transmitter cannot be easily removed, but in this case the effect will be lost if the person removes the transmitter and removes the transmitter from the body. Also, a method of making the transmitter a pendant type or a presslet type so that it can be attached to the neck or arm so that it cannot be removed, and a method of locking the doorway to confine the person to be monitored are monitored. It is not a preferable system because it will damage the human rights of those who

[0003]

[Problems to be solved by the device]

 When monitoring a wandering elderly person, there is a demand for a device that can monitor in a comfortable environment without damaging the human rights of the person. This invention provides an entrance / exit monitoring device for monitoring exit / exit of an entrance / exit of only a specific moving object without attaching a transmitter or the like to such a human body or a moving object or carrying the same.

[0004]

[Means for Solving the Problems]

 The object of the present invention is to provide a monitoring unit having a detection sensor for detecting the passage of a moving object and outputting a detection signal, and an alarm for receiving the output of the detection signal and outputting an alarm signal for a predetermined time. And an alarm control section having means, and a portable portable section having an alarm blocking signal generating means for outputting an alarm blocking signal capable of interrupting the alarm signal or blocking the generation of the alarm signal. In (1), it is achieved by an entrance / exit monitoring device that activates the alarm means when the signal of the alarm blocking generation means is not received. When a device for transmitting the output of the detection signal from the monitoring unit by radio waves is additionally provided, the wiring between the monitoring unit and the alarm control unit is wireless, and a telephone notification system using a telephone with simple construction. Can be realized. In this way, even after the detection signal is output and the alarm is issued, it is possible to monitor the passing object at the entrance and exit by stopping the alarm signal by the alarm blocking signal from a distant position. In addition, it is possible to interrupt the alarm from an external telephone.

[0005]

[Action]

 In the entrance / exit monitoring device of the present invention, when a moving object such as a person passes through the entrance / exit, the detection element in the monitoring unit detects it and outputs a detection signal. The detection signal received by the alarm control unit installed at a remote location is input to the AND gate. At that time, if the alarm blocking signal is not output from the alarm blocking signal generating means from the portable unit and the alarm blocking signal is not input to the AND gate in the alarm control unit, the alarm circuit timer is activated by the output of the alarm circuit timer. However, a warning sound is generated from a speaker or the like. However, when the alarm blocking signal from the alarm blocking signal generating means by the operation of the mobile unit is received, reproduced and input to the AND gate, the alarm circuit timer does not operate and no alarm sound is generated. .. At this time, the output of the receiver generated by the activation of the alarm blocking generation means and the reset signal operate the timer for the alarm blocking signal to obtain the duration of a certain time, and the reset signal having this duration is It closes the AND gate and works on the reset terminal of the alarm circuit timer to reset it.

If a button of the alarm blocking signal generating means is pressed within a predetermined time of the alarm blocking signal generating means, for example, within 10 seconds before the time when the passage of the moving object is sensed, a timer for the alarm blocking signal The alarm signal does not sound because the reset signal maintained at does not pass the sensing signal to the AND gate. In this way, when a watcher, a nurse, or a moving object that is not monitored passes through the entrance / exit, the alarm can be stopped by operating the transmitter of the person to send an alarm blocking signal. Also, if the detection element senses that a moving object has passed and the alarm starts to sound, pressing the button on the mobile unit resets the timer for the alarm circuit by the alarm blocking signal, so the alarm is interrupted. Without the need to attach a transmitter to a moving object monitored by this means, it is possible to automatically monitor the state in which an old man or an infant goes in and out of a room. In addition, even if an illegal intruder who does not have a mobile unit passes through the doorway, an alarm will sound, which will serve as security.

【Example】

 1 is an explanatory view arranged in the entrance / exit monitoring device according to the present invention, FIG. 2 is a time chart of a detection signal, an alarm blocking signal and an alarm generation, FIG. 3 is the same time chart as FIG. 2 of another embodiment, and FIG. FIG. 5 is a schematic view of a transmitter of an embodiment arranged in the entrance / exit monitoring device of the present invention, and FIG. 5 is a schematic layout of an entrance / exit monitoring device of the embodiment of the present invention. Reference numeral 1 is a monitoring unit composed of a detection element 3 for detecting passage of an object including an infrared sensor or an ultrasonic sensor, and a transmitter A14 for transmitting a detection signal of the detection element 3, such as a window or a door. It is located in the vicinity. Reference numeral 2 denotes a mobile unit provided with an alarm blocking signal generator 4 and a transmitter B15, which is carried by a moving object on the monitoring side such as a watcher or a caregiver, or placed at a remote location from the watcher 1. I am doing it. The transmitter A14 in the monitoring unit 1 and the transmitter B15 in the mobile unit 2 generally use radio waves in the UHF band. Reference numeral 5 is an alarm blocking signal timer which operates in response to the output signal of the receiver B17 provided in the alarm control unit 13 which receives the signal from the transmitter B15, and extends the duration of the received alarm blocking signal.

Reference numeral 6 designates a logical product gate A in the alarm control unit 13 for inputting the sensing signal demodulated by the receiver A 16 which receives the sensing signal from the transmitter A 14, and the alarm blocking signal timer 5 The logical product of the alarm blocking signal output from the receiver and the sensing signal demodulated by the receiver A16 is obtained. Reference numeral 7 is an alarm circuit timer that keeps the signal to the alarm circuit for a certain period of time. Reference numeral 8 is an alarm circuit, 9 is a notification circuit timer, and 10 is a reset set type flip-flop (hereinafter referred to as RSFF), which transmits a signal to the AND gate B11. Reference numeral 12 is a multi-function telephone which receives an output signal from the AND gate B to make a telephone call for a notification.

Next, the operation of the entrance / exit monitoring device of the present invention will be described. When a moving object passes through the entrance / exit where the monitoring unit 1 is installed, the detection element 3 of the monitoring unit 1 is activated and the transmitter A14 transmits a radio wave transmitting a sensing signal. This detection signal is received by the receiver A16 of the alarm control unit 13, demodulated and input to the AND gate A6. At this time, if the alarm blocking signal has not been separately received by the receiver B17, the gate is open, so the alarm circuit timer 7 is triggered by the output from the AND gate A6. Then, the alarm circuit 8 is activated for a certain time (for example, about 20 seconds), and an alarm sound is generated to notify the passing of the moving object. However, with such a monitoring device, the alarm sounds even when the person being monitored passes by not only the elderly and infants to be monitored. Therefore, the mobile unit 2 is attached to an object other than a moving object to be monitored or a person to be monitored, and the push button of the alarm blocking signal generator 4 is operated when passing through the entrance / exit where the monitoring unit 1 is installed. .. The radio signal of the transmitter B15 transmitted at that time is received by the receiver B17 and demodulated into an alarm blocking signal. This signal triggers the alarm blocking signal timer 5.

The triggered alarm blocking signal timer 5 converts the alarm blocking signal into a signal that lasts for 10 seconds, during which it operates to close the AND gate A6 so that the sensing signal can trigger the alarm circuit timer 7. Absent. When the alarm circuit timer 7 has already been triggered by the sensing signal and its output has been turned on, the output of the alarm blocking signal timer 5 resets the alarm circuit timer 7, so that the alarm circuit 8 stops issuing the alarm. In this way the watcher can pass through the doorway without sounding an alarm. 2 and 3 show timing charts of the sensing signal, the alarm blocking signal, and the alarm. For 0 to 30 seconds in the time chart of FIG. 2, the moving object to be monitored passes through the entrance and exit, and the detection signal from the detection element 3 is transmitted, but the alarm blocking signal from the mobile unit 2 is the alarm control unit. Since it is not received at 13, the alarm is issued from the alarm circuit for the specified 20 seconds. Next, after 30 seconds have elapsed in the time chart of FIG. 2, after the detection signal has appeared, the alarm blocking signal is output from the alarm blocking signal generator 4 of the mobile unit 2, and the alarm signal is generated. Is less than the prescribed 20 seconds. Therefore, the alarm is interrupted by the alarm blocking signal.

The tom chart in FIG. 3 shows a state in which a family member or the like who is monitoring an old person or an infant passes through the doorway for 0 to 20 seconds without sounding an alarm. After the alarm blocking signal generated by pressing the send button 21 of No. 4 is transmitted from the transmitter B15 and demodulated by the receiver B17, the alarm blocking signal timer 5 extends the duration and closes the AND gate A6. Therefore, the sensing signal generated within 10 seconds cannot pass through the AND gate A6 and the alarm does not sound. After 20 seconds in Fig. 3, the alarm blocking signal appears, but the detection signal passing through the AND gate A 6 after the extended alarm blocking signal was cut off because the passage at the entrance did not finish within 10 seconds. In this embodiment, the alarm circuit timer 7 is triggered to cause the alarm circuit 8 to generate an alarm.

When it is desired to cancel the alarm, the transmission button 21 of the alarm blocking signal generator 4 may be pressed again. In order to avoid false alarms caused by slow passage through the entrance / exit, there is a method to make the alarm blocking signal timer 5 longer than 10 seconds, but if this duration is long, the housekeeper The unprotected state of the entrance and exit that occurs after the exit of the car will prolong, and the alarm circuit will not operate even if an old man or infant being monitored passes by. When a moving object to be monitored, that is, an elderly person or an infant passes through an entrance / exit, it is possible to add more complete monitoring by adding a function to call nearby relatives and cooperators by telephone. The notification in this case is realized, for example, by using the multi-function telephone 12 having a function capable of auto dialing by contact input. However, the time of notification is set not when the alarm signal appears, but when the alarm blocking signal does not appear even after the appropriate notification waiting time by the notification circuit timer 9.

If the waiting time for notification made by the notification circuit timer 9 is too long, the meaning of emergency notification is lost. However, if it is too short, when an old person to be monitored passes and the alarm sounds, even if the family member notices and interrupts the alarm, the multifunctional telephone 12 automatically notifies the person, and it causes trouble to external cooperators. Will be hung. The sensing signal from the monitoring unit 1 is received by the receiver A16 in a state where the alarm blocking signal from the portable unit 2 is not transmitted, and the notification circuit timer 9 and the RSFF 10 are triggered by the output from the AND gate A6. The notification circuit timer 9 is a timer for determining a notification waiting time and generates a pulse signal having a width of 1 second after 15 seconds. The RSFF 10 is set by the output of the AND gate A6 and is reset by the output of the alarm blocking signal timer 5. The alarm blocking signal is output by the flip-flop. Reset on falling. Therefore, if both the notification circuit timer 9 and the RSFF 10 are triggered by the output of the AND gate A6 and the RSFF 10 is not reset by the output of the alarm blocking signal timer 5 for 15 seconds, it is considered that there is no alarm blocking signal. Then, the multi-functional telephone 12 is used to notify the neighboring collaborators.

A control method using a telephone line can be performed by a conventionally known method. In this system, it can be easily realized that the alarm circuit is reset or the alarm is stopped from the notified telephone destination. In the above-mentioned embodiment, the infrared sensor is used as the passage detecting element 3 for detecting the passage of the moving object through the entrance / exit, but it can be realized by replacing with a heat ray sensor, an ultrasonic sensor or a foot switch. Although the UHF band radio frequency is used for the portable alarm blocking signal generator 4, another radio frequency band may be used. Further, in the embodiment, the method of wirelessly transmitting the signal of the alarm blocking signal generator 4 to the receiver B17 has been described, but when the person to be monitored is always near the main body with the alarm control unit or the telephone, the transmitter B15 is used. The receiver B17 can be eliminated and the alarm blocking signal generator 4 and the alarm blocking signal timer 5 can be directly connected by a wire or the like.

As another embodiment of the present invention, a pendant type portable transmitter for hanging on a neck or the like and a monitoring device are shown in FIG. A push button 21 is provided on the transmission pendant 20 of the mobile unit 2, and the alarm blocking signal generator 4 and the transmitter B15 are incorporated therein. On the other hand, a device incorporating the alarm control unit 13 and the monitoring unit 1 is shown, which includes a detection element 23 which is an infrared sensor, an alarm control circuit 24 such as a logical product gate A, and a reception unit 22 which receives signals from a transmitter B15. A speaker 25 for emitting an alarm sound, an alarm sound changeover switch 27 and a battery 26 are provided. The entrance / exit monitoring device of the present invention can be constructed by arranging such a device at the entrance / exit.

FIG. 5 shows an embodiment of the system of the entrance / exit monitoring device of the present invention. An entrance / exit sensor is arranged above the entrance door on the entrance side. The entrance / exit sensor 31 has a built-in detection element 3 and a transmitter A14, an antenna, and a release button 32 connected thereto. An alarm control unit 33 having a built-in receiver for receiving a detection signal and an alarm blocking signal and an alarm member is arranged between the reception room and connected to the telephone 34 by an electric wire or the like. On the other hand, in the cooking chamber, there is installed a portable section 35 having a built-in alarm blocking signal generator and transmitter. When an elderly person or the like goes out of the entrance / exit, the entrance / exit sensor is activated to generate an alarm. In the cooking room, a family member can operate the mobile unit 35 to output an alarm blocking signal to interrupt the alarm and trace the alarm to bring the old man back. When the family goes out, the alarm can be stopped by operating the carrier section 35 or the release button 32 at the entrance / exit. In addition, when an old man or the like passes through the doorway while the family is away, the alarm control unit 33 can automatically contact an external facility or the like via the telephone 34.

In the above-described embodiment, the embodiment has been described in which the watcher or the like carries the mobile unit and the alarm blocking signal is generated by the operation (push button, etc.) of the mobile unit. By incorporating a transmitter that emits radio waves and detecting the radio waves at or near the entrance monitoring section to generate an alarm blocking signal, the operation at the time of passage can be omitted. A resonance tag is used instead of the transmitter of the mobile unit, a resonance tag sensor is installed at the entrance and exit, and the output is used to open and close the AND gate A to prevent an alarm when passing. It goes without saying that it can be omitted. Further, a method of disposing the sensing signal blocking means near the entrance and exit so as not to give an alarm by being operated by a watcher or a caregiver is shown in the embodiment of FIG. In this case, it is necessary to arrange it so that it will never be detected by the old people being monitored.

[0018]

[Effect of the device]

 Although it needs to be monitored, this device is positioned as a method suitable for the demand to create a free atmosphere with the maximum flexibility. For example, when observing an old man with a wandering habit, if you lock it up in a room, you can save labor, but from the standpoint of being monitored, you want to be as natural as possible. By implementing this invention, it is possible to monitor the exit from the room without forcing the person to be monitored to carry a monitoring transmitter and the like, and without being noticed by the person himself.
