Description

  The present invention relates to a highly functional door phone device capable of stopping an electrical device in a house when all members of the house go out.

  As shown in FIG. 9, 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. 9 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. The response terminal 103 is provided with a ringing tone signal generator 132 that generates a ringing signal in response to an operation of the ringing switch 122, and is amplified by the amplifier 133 to output a ringing tone 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. 10, 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. 10 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. 10 described above (Patent Document 1) has restrictions on the number of people 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 sufficient capacity via another interface, for example, a cordless telephone master unit, and the visitor is displayed with the received image. A technique has been proposed in which identification processing is performed, notification processing for personal authentication is performed, and predetermined ringing tone information is transmitted to a selected calling device, for example, a cordless telephone cordless handset. Information such as a ringing tone is stored in the memory of the external connection terminal device (see Patent Document 2).
Japanese Patent No. 32509797 JP 2000-287196 A

However, as recorded as H16, 01, 20, 15, 32, no response, it was found that he visited at 15:32 on January 20, 2004 and did not respond. These are automatically recorded by the response history recording means 39b. Also, 38b ₁₆ by pressing the corresponding reject keys in the input keyboard 11, a rejection flag is set in the reject portion 38b _2, are set in the reject portion 38b ₂ by the response prohibiting setting means 39c. These pieces of information are all related to the name of the person who has performed image authentication, and the visit history area 7c and the rejection flag 38b ₁₆ of the display unit 7 shown in FIG. 1B are displayed in the warning area 7b using a template.

Next, FIG. 5 (b) shows the personal information section for the constituent persons in the home, 38b ₁₇ is the home member history in which both going out and returning home are recorded, and 38b ₃ is counted up by the counter section 37b. It is a count value that stores a flag to indicate. For example, in the in-house member history 38b ₁₇ , the father's H17, 02, 01, 08, 10, going out, face authentication is determined by the camera 2 to go out by the camera 2 at 8:10 on February 1, 2005. At this time, it is shown that the father is working with face recognition as the first person to go out. The day after that, my son Taro went out to go to school at 8:30, and his mother went out at 13:00 in the afternoon. Thus the counter portion 37b is counted everyone going out, and stores the flag of all go to the count value 38b _3. Therefore, when this flag is stored, the electrical equipment in the house is turned off by the absence control execution means 39h and each electrical equipment control means of the doorphone master unit 6.

  Next, on February 2, 2005, his son Taro went to school earlier than his father at 8: 1, and was face-identified as the first person to go out. Thus, since the first person who goes out of the house performs the image authentication by the face, it is not necessary to perform the image authentication for all the persons thereafter, and the number of persons going out can be counted by the sensing sensor 12. If the back view is image-authenticated for everyone, there may be a misjudgment in some cases. However, since the first person reliably authenticates the image and the remaining number is counted by the sensor sensor 12, the misjudgment of the first person is The subsequent processing is also simplified. And the determination precision by the going-out determination part 37a can be improved in consideration of the information from the power sensor 62 and the weight sensor 63.

  Here, the connection state between the door phone device of the first embodiment and the household electric appliances, the power sensor, and the weight sensor will be described. FIG. 6 is an explanatory diagram illustrating a connection state between the door phone device, the home electrical device, and each sensor according to Embodiment 1 of the present invention. In FIG. 6, 60 is a television controlled by the doorphone master unit 6, and 61 is a lighting fixture similarly controlled by the doorphone master unit 6. When the number of electrical devices controlled by the door phone master unit 6 increases, the number of connection terminals 53 increases, wiring becomes complicated, and when physical installation becomes difficult, a wireless communication I / F unit (not shown) is installed. It is preferable to configure and control the wireless LAN.

  Also, 62 is a power sensor that can detect the amount of power used in the house, and 63 is a weight sensor that can measure changes in the building weight. The detected information on the amount of power used and the weight of the building detected in these steps is input to the intercom base unit 6, and it is determined whether or not each exceeds a predetermined threshold value. Normally, only one of them needs to be installed. The information of each sensor is considered in order to determine the start of control of each electric device. However, when it is detected that the detection amount exceeds the threshold value in each sensor, the absence control execution means 39h On the condition that the authentication unit 37 succeeds in authentication and the counter unit 37b counts up, information from each sensor is added to determine whether to start the electric device control.

  As described above, in the door phone device according to Embodiment 1 of the present invention, when there is a visitor, the visitor is specified by image authentication, and in addition to the name, company name, telephone number, etc., the related information such as visit history information Since the information is displayed on the door phone master unit, you can prevent troubles by seeing this display, or you can obtain influential information of this visitor before actually visiting the visitor, Visitors can be handled easily and quickly.

  In addition, when a person in the house is image-authenticated like a family and it is determined that the person is going out, the counter unit counts the number of outing persons counted by adding 1, and the count reaches a predetermined value. When it is determined that all of them have gone out, it is possible to automatically stop the electric devices in the house or control them to the power saving mode.

(Embodiment 2)
The door phone apparatus according to Embodiment 2 of the present invention performs person authentication by voice. The door phone device of the second embodiment is different from the door phone device of the first embodiment that performs image authentication in that voice authentication is performed, and the other configurations are the same. FIG. 7 is a block configuration diagram of the door phone master unit of the door phone device according to Embodiment 2 of the present invention, and FIG. 8A is a block diagram of the control function means of the door phone master unit of the door phone device according to Embodiment 2 of the present invention. FIG.8 (b) is a block diagram of the database part in Embodiment 2 of this invention. The door phone device according to the second embodiment and the door phone device according to the first embodiment have basically the same configuration, and the same reference numerals indicate the same configuration.

  In FIG. 7, reference numeral 49 denotes an audio signal input from the microphone 4 of the door phone slave unit 1 and encoded, or an audio signal from the microphone 9 is encoded and the audio authentication unit 50 (to be described later) performs spectrum analysis and the like. It is an A / D / D / A conversion unit that passes it as digital data and then decodes it and outputs it to the audio processing unit 40 or the speaker 8. Reference numeral 50 denotes a voice authentication unit that samples a digital voice signal output from the A / D / D / A conversion unit 49 and extracts a feature point to authenticate a person.

  As is well known, human voiceprints differ from person to person, and specific voice segments input from microphones 4 and 9, for example, “who”, “sorry”, “who ’s calling” "Is it home? (Question)" is converted into a digital signal, the characteristic parameters of each individual are extracted from the analysis of the spectrum, etc., and the characteristic parameters of the acquired voice data stored in advance are compared. The distance between the two feature spaces is measured, and if they are within a predetermined range, it is estimated that they are the same person. It is preferable to store data in advance using feature points of acquired data as parameters.

  In this case, the voice authentication unit 50 can estimate whether or not the person is the same person by cutting out a specific voice section and comparing the parameters. Therefore, a comparison with a large number of people can be performed immediately. Similar to the image of the first embodiment, the acquired voice data stored in the database unit 38 can be easily updated by pressing the update key in the input keyboard 11. In addition, as a method used for extracting and comparing feature points of voice authentication, there are many methods such as a method using a fast Fourier transform (FTT) and a line spectrum pair (LSP) recently. It is good to use.

  In FIG. 8A, reference numeral 39i denotes voice data updating means that is executed when it is desired to update the acquired voice data stored in the database unit 38 to the latest voice data. As already described, it can be updated by pressing the voice update key in the input keyboard 11. In addition, by pressing and holding the voice update key, an automatic setting function can be provided. In this case, if there is a visit, the voice data can be automatically updated.

  In FIG. 8B, reference numeral 38d denotes a voice data part stored in the database part 38 in association with acquired voice data, a feature parameter of the voice data, and a name thereof. The contents of the personal information part 38b corresponding to this are the same as those in the first embodiment, and the description thereof is omitted.

  Incidentally, in the second embodiment, the voice authentication unit 50 is provided, and the voice data update unit 39i and the voice data unit 38d are provided. However, this includes the image authentication unit 37 of the first embodiment, the image data update unit 39d, The image data unit 38a cannot be provided side by side, and it is also preferable to improve both by providing both at the same time. In this case, for example, after image authentication by the image authentication unit 37, voice authentication by the voice authentication unit 50 is performed, and it is estimated that the person is the same person only when the distance on the feature space is within a predetermined threshold. Become. The reverse is also possible.

  As described above, the door phone device according to the second embodiment has the same effect as the door phone device according to the second embodiment when the environmental condition for taking an image changes, and the possibility that the authentication may be hindered by an accessory such as glasses. However, voice is resistant to these environmental conditions and can be authenticated relatively easily than image authentication.

  Then, when the person in the house is image-authenticated like a family and it is determined that the person is going out, the counter unit counts by adding 1 to the number of outing persons counted, and the count reaches a predetermined value. When it is determined that all of them have gone out, it is possible to automatically stop the electric devices in the house or control them to the power saving mode.

  INDUSTRIAL APPLICABILITY The present invention can be applied to a highly functional door phone device that can stop an electrical device in a house when all of the persons go out.
