Description

  The present invention relates to an alarm device that detects an intruder from outside and issues an alarm.

  Conventionally, as such an alarm device, the sound data of the opening / closing sound of the hinged door is stored in the storage unit, and when an abnormal sound occurs, the abnormal sound is converted into sound data and the sample data stored in the storage unit by the control unit On the basis of whether or not it is an abnormal sound, if both match, it is possible to notify the communication destination mobile phone registered in advance by the communication unit of the abnormality (for example, patent document) 1).

JP 2002-31860 A (claims, paragraph numbers [0005], [0007], [0009] to [0011], FIG. 1)

  However, in the above prior art, since it is audio data, there is a problem that must be solved, such as being unable to cope with the case where the hinged door is opened slowly so as not to make a noise.

  In view of the problem that cannot be dealt with when the hinged door is slowly opened, the present invention is based on the above-described prior art, and a sound pressure sensor for detecting low-frequency sound accompanying the air flow generated when the hinged door is opened and closed, and a plurality of types of hinged doors The storage means for converting the waveform pattern of the low frequency sound generated in the data into data and storing it in advance and the electrical signal from the sound pressure sensor and the stored data extracted from the storage means are compared and matched, and the detection signal By providing a CPU that outputs a signal and an alarm means that is activated by an output signal from the CPU, the air flow that is always generated when the hinged door is opened and closed can be targeted, so that even when the door is opened slowly, it can be dealt with. Solve the above problems.

In short, the present invention converts the sound pressure sensor for detecting the low frequency sound accompanying the air flow generated when the hinged door is opened and closed, and the waveform pattern of the low frequency sound generated by the multiple types of hinged doors into data and stored in advance. Storage means, a CPU that outputs a detection signal when the electric signal from the sound pressure sensor and the stored data extracted from the storage means match, and an alarm means that operates according to the output signal from the CPU. Therefore, since such an alarm device does not react with other sounds, it can react and issue an alarm even if the hinged door is opened slowly so that the opening and closing sound of the lock, the squeaking sound of the hinge, etc. do not stand.
In addition, it is equipped with an air pressure sensor to detect the weak air vibration that occurs when the air pressure changes when the hinged door is opened and closed, and the electrical signals from both the sound pressure sensor and the air pressure sensor are compared with the stored data to match the two. In such a case, since a detection signal is output from the CPU and the alarm means is activated, it is determined that an intrusion has occurred due to the abnormality detection of both, so that it is difficult to malfunction.

  The alarm device according to claim 1 or 2 is provided with receiving means, wirelessly connecting the receiving means and a magnet sensor installed in each opening, and the receiving means receives the "OFF" signal from the magnet sensor. Then, since a detection signal is output from the CPU and the alarm means is activated, if a magnet sensor is installed in the hinged door that does not easily generate an opening / closing sound, intrusion from the opening can be prevented.

  In many cases, a resident who has returned home is attacked indoors by an intruder who has already sneak in, the intruder returns home and is attacked, or a serious health abnormality occurs in the resident. The alarm device according to claim 2 is provided with receiving means, the remote control for remotely operating the alarm device is provided with an emergency button and means for transmitting the "ON" signal of the emergency button, and means for receiving the "ON" signal of the emergency button When the alarm is received, the alarm means is activated by outputting a detection signal from the CPU, so if the emergency button on the remote control is pressed even if the above situation occurs, the intruder will be repelled by the alarm means or the neighbor will be urgent For example, if it is an automatic communication to the respondent who has designated an arbitrary number of alarm means in advance, if an emergency button is pressed, an emergency alert will be sent to the designated respondent Door can be.

  Because the alarm means is an alarm sound generation means, the intruder, living people and neighbors can hear the warning sound directly, so that the intruder can be surprised and repelled, or the living person and neighbor can be rushed .

Since the alarm means is a communication means that automatically reports to the designated respondent's terminal, it is possible to automatically notify the intrusion alarm and the emergency alert by the emergency button on the remote control by communicating with the designated respondent's terminal, You can receive intrusion / emergency calls wherever you are, and make the alarm device callable by operating buttons on the respondent's terminal, or make it possible to hear only room sounds. You can also.
In addition, it is possible to specify a plurality of designated respondents, set the order of notifications, and provide the communication means with a function that keeps reporting according to the order until there is a reply from the terminal of the respondent. It is also very practical that the emergency alert by the emergency button on the remote control can be confirmed by someone in the designated respondent.

  The alarm device according to the present invention mainly includes a device main body 1 and a plurality of magnet sensors 2, 2a... Wirelessly connected to the device main body 1.

As shown in FIGS. 1 and 2, the apparatus main body 1 includes a sound pressure sensor 3 for detecting a low frequency sound (18 Hz or more) accompanying an air flow generated when the hinged door D is opened and closed, and preferably the sound pressure sensor. 3 and the air pressure sensor 4 for detecting the weak air vibration (18 Hz or less) generated by the air pressure change at the time of opening and closing the hinged door D. The sound pressure sensor 3 or the sound pressure sensor 3 and the air pressure sensor 4 are provided. When the sound and air vibration electrical signals detected by both are input to the CPU 5 and compared with the data stored in the storage means 6, it is determined that an abnormality has been detected, a detection signal is output, and the alarm means 7 is activated. I have to.
The outputs from the sound pressure sensor 3 and the air pressure sensor 4 are preferably amplified by the amplifying means 15 and 16 and output to the CPU 5.

In the magnet sensors 2, 2a, as shown in FIG. 1, when the sensor main body and the transmission device are set as a pair and both are arranged close to each other and the sensor main body is separated from the transmission device, the transmission device is “OFF”. It is configured to transmit a signal, and there is a type that is installed in a hinged door like the magnet sensor 2 in FIG. 1, or a type that is installed in both sliding doors like the magnet sensors 2a and 2b in FIG. Especially in the latter case, if a transmitter is installed at the central part of the inner door and a sensor body is installed at the opposite position of the inner door on the outer door, one magnet sensor can be used for one opening. become.
Further, the apparatus main body 1 is provided with a receiving means 8 such as an “OFF” signal of the magnet sensors 2, 2a, etc., and the signal received by the receiving means 8 is input to the CPU 5, and a detection signal is output from the CPU 5 and an alarm means is provided. 7 is activated.
That is, the change detected by the sound pressure sensor 3 and the air pressure sensor 4 is converted into an electrical signal, and when the frequency, waveform pattern, etc. match the stored data, it is determined that an abnormality has been detected and an alarm is executed. .

The device main body 1 has an “all warning mode” in which both the sensors 3 and 4 and the magnet sensors 2, 2a... On the device main body 1 side are warned, a “partial warning mode” in which only the magnet sensors 2, 2a. The warning mode can be changed like a “release mode” for releasing the warning in both the main body 1 and the magnet sensors 2, 2a.
The remote controller 9 for remotely operating the apparatus main body 1 includes an emergency button 10 in addition to the alarm mode switching button 10 and also includes a transmission signal 12 for a switching signal by the switching button 10 and an emergency signal by the emergency button 11. When the switch body 10 and the emergency button 11 are pressed and the signal transmitted from the transmission means 12 is received by the apparatus body 1, the alarm mode of the apparatus body 1 is changed or the alarm means 7 is activated.

In the alarm means 7, the alarm sound generating means 13, or the terminals AT1, AT2 ... of the intrusion alert recipients AP1, AP2 ... or the terminals ET1, ET2 ... of the emergency alert recipients EP1, EP2 ... In the former case, an alarm sound is generated by the alarm sound generating means 13 after the abnormality is detected, and in the latter case, after the abnormality is detected, the intrusion alarm respondent AP1 is detected from the apparatus body 1 after the abnormality is detected. , AP2... Or emergency alert respondents EP1, EP2..., ET1, ET2,... .., Or emergency alarm respondents EP1, EP2..., Terminals ET1, AT2... ET1, ET2. .
It is preferable that the alarm means 7 is composed of both the alarm sound generating means 13 and the communication means 14.

Next, the operation of the alarm device according to the present invention will be described.
Both the “main alert mode” that guards with both the device body 1 and the magnet sensors 2, 2a, “partial alert mode” that guards only with the magnet sensors 2, 2a, and both the device body 1 and the magnet sensors 2, 2a… The warning mode can be changed like "Release mode" to cancel the warning at the home, so that the warning mode when you are away is set to "All warning mode", and the warning mode when you are at home is "Partial warning mode" or "Cancel" For example, when going to the toilet during sleep, the hinged door D is opened and closed with certainty, so the main unit is set to the “partial warning mode” and the main function (abnormality detection function using the sound pressure sensor 3 and the air pressure sensor 4). However, if only the magnet sensors 2, 2a,... Installed and wirelessly connected to each opening are in the “ON” state, safety can be ensured by eliminating the risk of external intrusion.
The remote control 9 can be used to remotely change the “all warning mode”, “partial warning mode”, and “cancellation mode”, and press the switch button 10 before opening the hinged door D when returning home. Can be shifted from “all warning mode” to “release mode”.

  And the low frequency sound (18 Hz or more) accompanying the air flow generated when the intruder opens the door D is detected by the sound pressure sensor 3 and output as an electrical signal, and the output from the sound pressure sensor 3 is amplified. Amplifying by means 15 and outputting to CPU 5, and opening the hinged door D causes room air to be slightly sucked and discharged outside the room, and the air pressure inside the room changes to give a predetermined frequency (10 to 0) in the room. .1 nHz) is generated, and this vibration is detected by the air pressure sensor 4 and converted into an electrical signal for output. The output from the air pressure sensor 4 is amplified by the amplifying means 16 and output to the CPU 5 for storage. Compared with the data, it is determined that the two match, and the alarm means 7 is activated, but if they do not match, the alarm means 7 is not activated.

Since the communication means 14 is provided in the apparatus main body 1, the telephone numbers of a plurality of respondents are registered in advance, and preferably the emergency alarms are notified by the intrusion alarm respondents AP1, AP2,. It is also possible to divide and register them as those of the persons EP1, EP2,..., And provide the apparatus body 1 with the above-mentioned telephone number auto-dial function to automatically notify after the abnormality is confirmed.
For example, after confirming the abnormality by the sensors 3 and 4, it is set so that a plurality of designated intrusion alert recipients AP 1, AP 2... If the signal is not returned, the third and subsequent respondents AP3... Are notified in order until the confirmation signal is returned to the next secondary respondent AP2, and the confirmation signal is also sent from the final respondent APn. If is not replied, the primary respondent AP1 is notified again and the above steps are repeated.
In particular, in the “all warning mode”, a warning sound is generated by the warning sound generation means 13 after the abnormality is confirmed, and if the confirmation signal is not returned from the respondents AP1, AP2,. You may make it ring.
Even if the reporters AP1, AP2,... Make the terminals AT1, AT2,... In a call state and hear an alarm, if the confirmation signal is not returned, the reporters are notified to the next reporter.

In addition, there are many cases where a resident who has returned home is attacked indoors by an intruder who has been sneaking in, an intruder returns home and is attacked, or serious health abnormalities occur in the resident. If the emergency button 11 of the remote control 9 is enabled so that the function of the main body 1 can be selected as “all warning mode”, “partial warning mode” or “release mode”, the device main body 1 even if it is “release mode” The alarm sound will sound to repel intruders and inform neighbors, and if they are not registered, notify emergency alerts to registered emergency alert respondents EP1, EP2 ... Is also possible.
The reporting method may be the same as the reporting method for the intrusion alarm.

The communication means 14 of the apparatus main body 1 has a function equivalent to that of an ordinary fixed telephone, and connects the modular jack MJ on the residential side and the apparatus main body 1, and connects the fixed telephone FT and the apparatus main body 1 to connect the fixed telephone FT Are connected to the modular jack MJ via the apparatus main body 1, respectively, and the apparatus main body 1 is connected to the storage communication network W. In the case of an intrusion alarm or emergency alarm, a message from the apparatus main body 1 is sent. After confirmation, the confirmation signal of the notification is returned to the apparatus body 1 by operating the buttons of the terminals AT1, AT2,..., ET1, ET2,. Or making the apparatus main body 1 in a communicable state or listening to room sounds on the apparatus main body 1.
In addition to the above functions, the current alarm mode of the apparatus main body 1 is confirmed, the alarm mode of the apparatus main body 1 is changed, or an alarm sound is sounded when the apparatus main body 1 is in the “release mode”. Remote operation is also possible.
That is, the CPU 5 on the apparatus body 1 side determines the operation to be performed by electronic sound when the buttons of the terminals AT1, AT2,..., ET1, ET2,. Then, the operation to be performed is executed.
However, the above description is based on the premise that the apparatus main body 1 is connected to the modular jack MJ. When the apparatus main body 1 is not connected, the alarm sound is set to sound for a predetermined time each time the intrusion is confirmed.

  In addition, in FIG. 1, there are three intrusion alert respondents AP1, AP2,... And emergency alert respondents EP1, EP2,..., But the number of persons is not limited to this. Any number of people is acceptable as long as it is within that number.
