Description

  The present invention relates to a door phone device that accommodates unexpected and suspicious visitors.

  As shown in FIG. 7, the conventional door phone device 101 is composed of two devices, a door phone terminal 102 and a response terminal 103 arranged in the house. FIG. 7 is a schematic configuration diagram of a conventional door phone device. The door phone terminal 102 includes a camera 121 that shoots a visitor and outputs an image signal representing the image, a call switch 122 that is operated by the visitor, and a speaker 123 that informs the visitor of voice from the home. And a microphone 124 for transmitting the voice of the visitor to the house.

  The camera 121 is connected to the image display unit 131 in the response terminal 103, and the image signal from the camera 121 is processed by the image display unit 131, and the visitor's face is displayed on the monitor. In addition, the response terminal 103 is provided with a sound signal generator 132 that generates a call signal in response to an operation of the call switch 122, amplified by the amplifier 133 and output from the speaker 134. Furthermore, the response terminal 103 is provided with a handset 136 connected to the speaker 123 and microphone 124 of the door phone terminal 102 via the amplifier 135 in order to make a call in response to the ringing tone, and respond to the ringing tone. Accordingly, when the respondent picks up the handset 136, a communication circuit is formed between the door phone terminal 102 and the response terminal 103, and the camera 121 and the image display unit 131 are activated.

  However, in this conventional door phone device 101, when a call is made, the person in the house picks up the handset 136 and actually talks, and does not perform operations such as operating the camera 121 and the image display unit 131. The person who operated the call switch 122 could not be confirmed.

  Therefore, as shown in FIG. 8, a person database 142 storing image data related to a person who may operate the call switch 122 of the door phone terminal 102 and image data of the person who operated the call switch 122 are captured. And a person authentication door phone apparatus that includes an image recognition unit that compares image data stored in the person database 142 with each other (see Patent Document 1). FIG. 8 is a schematic configuration diagram of a conventional person authentication door phone apparatus.

  According to the door phone device 101, when the call switch 122 is operated, the control unit 143 operates the camera 121, the image display unit 131, the image recognition unit 141, and the person database 142, and the image recognition unit 141 transmits from the camera 121. The obtained image data of the operator is collated with each data stored in the person database 142. When the image data of this person is accumulated in the person database 142 as a result of collation of both image data, a paging sound peculiar to the person suitable for the correspondence of this person is read from the ringing sound database 144 and output from the speaker 134. To do. At this time, if the image data of the person is not accumulated, for example, a general ringing tone is generated depending on the setting relating to whether or not the ringing tone is generated.

  Whether or not to register the image data of the person is determined based on the result of person confirmation. When it is necessary to register, this image data is registered in the person database 142, and the data of the caller's ringing sound most suitable for the person is registered in the ringing sound database 144. It is also possible to update an image in the person database.

However, the doorphone device 101 of FIG. 8 described above (Patent Document 1) has a restriction on the number of persons that can be estimated by the memory capacity of the ringing sound database 144 and the like, and when changing the calling method, the doorphone terminal 102 is used. I had to redesign. For this reason, after the person authentication of the response terminal 103, the person authentication result information is transmitted to an external connection terminal device having a memory having a large capacity via another interface, for example, a cordless telephone master unit, and the visitor is displayed with the received image. A technique for identifying and performing personal authentication notification processing and transmitting predetermined ringing tone information to a selected calling device such as a cordless telephone cordless handset has been proposed. (Refer to Patent Document 2).
Japanese Patent No. 32509797 JP 2000-287196 A

  As described above, the person authentication door phone device of (Patent Document 1) takes in the image data of the person who operated the call switch 122 and collates it with the image data stored in the person database 142. It is possible to know who the operator is and to be able to respond to an appropriate operator for this operator.

  However, it is merely a notification that there was a visitor to a person who is suitable for handling the person who operated the call switch 122, and it cannot be said that the person authentication is sufficiently useful. It was. In addition, the number of people that can be estimated by the memory capacity is limited, leaving problems in terms of practicality.

  In this regard, the door phone device of (Patent Document 2) can store a personal authentication notification processing program and ringing tone information in an external connection terminal device via an interface. Although the technology was improved, it could not be said that the person authentication was useful enough. Basically, similar to the above-described conventional technique, the notification is made only to the most suitable person for the operator.

  Recently, local communities are not always safe as usual, and self-defense is required in each household. For example, if there is no response when calling on the door phone device, it will be a problem that it will be mistaken for absence and an unexpected situation will occur, and it is not limited to the above-described person authentication, but the function of the door phone device will be further enhanced. There is a need to improve.

  One example of such a case is a trouble with a visitor in front of the gate. In such a case, this alone causes trouble for the entire neighborhood, and if a person in the house directly meets and responds, the noise may further increase. In such a case, a door phone device having a function of suppressing this is expected.

It is determined that there is occurrence), and a warning message is output from the speaker 3 by voice guidance. However, it is considered relatively infrequent to exceed the threshold value three times or more in both sound pressure and vibration. In the present embodiment, the user can set a threshold value of sound pressure and vibration from the input unit. Therefore, instead of detecting both sound pressure and vibration, when either one of them exceeds the threshold value three times or more within a predetermined time, it is set that noise has occurred in front of the intercom 1 You can also. Further, even if the number of times that the threshold value is exceeded for both sound pressure and vibration is counted, for example, the set number of times of the sound pressure level is set to 3 times or more, but the set number of times that the vibration level exceeds the threshold value is set to 1 or more. The number of times can be set separately for both. In the present embodiment, the user can set the sensitivity of the sound pressure and the vibration sensor. When the sensitivity is detected by two sensors, the threshold of the vibration level is detected more than the threshold when the vibration level is detected alone.

  Therefore, in the first embodiment of the present invention, the operation (processing procedure) from when the door phone device detects a person who seems to be a visitor by the human sensor 12 to output a warning message and automatically call the police. . FIG. 4 is a flowchart of the operation of the door phone device in the first embodiment of the present invention, FIG. 5 is a second flowchart of the operation of the door phone device in the first embodiment of the present invention, and FIG. 6 is the first embodiment of the present invention. It is a 3rd flowchart of operation | movement of the door phone apparatus in FIG.

  The flowchart of FIG. 4 determines noise (such as noise) based on sound pressure and vibration. In FIG. 4, the human sensor 12 waits until a person who seems to be a visitor is detected (step 1). When this is detected, the camera 2 of the doorphone slave unit 1 is activated (step 2). In this step 2, the face information of the visitor photographed or imaged by the camera 2 is collated by the collating means 39c, and when it is determined that the person is a specific person, the input unit 45 can be set to operate the following steps. Is possible. Subsequently, the counter 14 is reset (step 3). Within one minute from the above detection, the sound pressure level of the sound detected by the microphone 4 is detected by the amplifier 27, and it is determined whether or not the predetermined value is exceeded (step 4). If not, return to step1.

When the sound pressure level exceeds a predetermined value within the predetermined time, 1 is added to the count number N ₁ of the counter 14 (step 5). As a result, it is determined whether the count number N ₁ has become three times or more within a predetermined time (step 6). If N ₁ within the predetermined time is smaller than 2 times, the process returns to step 4, and if the count number N ₁ is 3 times or more, the counter 14 is reset again (step 7).

Next, it is determined whether or not the vibration detected by the vibration detection sensor 13 exceeds a predetermined value within the same predetermined time (step 8). The vibration detection sensor 13 detects not only the vibration of the slave unit body but also the vibration of hitting or shaking the gate. If not, return to step1. When the vibration level exceeds a predetermined value, 1 is added to the count number N ₂ of the counter 14 (step 9). As a result, it is determined whether the count number N ₂ has become three times or more (step 10). When N ₂ is smaller than 3, the process returns to step 8, and when the count number N ₂ is 3 or more, the level determination means 24a notifies the main control section 39 of the doorphone master unit 6, whereby the voice guidance means 39a For example, a warning message such as “I will contact the police” in the response message section 47a is taken out and automatically output from the speaker 3 of the door phone slave unit 1 (step 11). The total of the vibration count and the noise count may be used as a reference for sending the response message.

  Thereafter, the timer unit 48 measures a predetermined time, for example, 10 minutes (step 12). At this time, whether or not there is a person in a region detectable by the human sensor 12 is determined by using the human sensor 12. The determination means 24a determines (step 13). For example, this determination can be made by detecting with a pyroelectric sensor or the like (step 13). In step 13, when it is determined that no person exists, the process returns to step 1, and when it is determined that a person exists, the automatic calling means 39b automatically calls the police (step 14).

  By the way, as described above, it is relatively rare that the threshold value is exceeded three times or more in both sound pressure and vibration. Therefore, instead of detecting both the sound pressure level and the vibration level, it can be determined that noise has occurred in front of the intercom 1 when either of the two exceeds the threshold value three times or more.

  Therefore, when it is determined that the noise is caused only when the sound pressure level exceeds three times, the determination is made from step 21 to step 30 as shown in the flowchart of FIG. This corresponds to the one obtained by removing step 10 from step 7 in FIG. Since the contents of step 1 to step 6 and step 11 to step 14 are the same as the contents of step 21 to step 30, description thereof is omitted because it is redundant. Similarly, when it is determined that there is noise only when the vibration level exceeds three times, determination is made at each step from step 41 to step 50 as shown in the flowchart of FIG. This corresponds to the one obtained by removing step 6 from step 3 in FIG. Since the contents of step 1 to step 2 and step 7 to step 14 are the same as the contents of step 41 to step 50, the detailed description is omitted as in the description of FIG.

Further, when changing the count number N, for example, the setting value of the sound pressure level count number N ₁ can be set to 3 times, and the setting value of the noise level count number N ₂ can be set to 2 times. . In addition, when lowering the threshold value of the vibration level below the threshold value when detecting alone, it is necessary to set it in the level determination means 24a of the door phone slave unit control unit 24.

  As described above, in the door phone device according to the first embodiment, when there is a noise (noise, vibration) in front of the door phone slave unit, this noise can be suppressed by sending a warning message first. When you do not leave, you can automatically make an emergency report to the police, so you can secure the safety of the neighborhood.

  The present invention can be applied to a door phone device that can suppress noise when there is noise in front of the door phone slave unit.
