Description

  The present invention relates to an interphone device and an interphone system.

  Conventionally, an audio signal is transmitted / received via a signal line between an interphone device (door phone slave unit) installed outside the house (for example, an outside entrance) and an interphone device (interphone master unit) installed in the house. By transmitting the video signal output from the imaging device provided in the doorphone slave unit to the interphone master unit via the same signal line, the video of the visitor captured by the imaging device is displayed on the monitor provided in the interphone master unit. However, an intercom system is provided in which a visitor and a resident can make a call (interphone call) using a doorphone slave unit and an interphone master unit, respectively (see, for example, Patent Document 1). In the interphone master unit, a function for recording video transmitted from the door phone slave unit (recording function) and a function for calling by calling another interphone device (interphone secondary master unit) installed in the house (extension call) Functions having various additional functions such as a function for locking and unlocking an electric lock provided on the entrance door (electric lock control function) are also provided. And, in the interphone master unit to which various functions are added in this way, naturally, an operation switch for receiving an operation input corresponding to each function and an operation button for operating the operation switch are necessary. If a dedicated operation switch and operation button corresponding to each function are provided, the size increases. For example, a liquid crystal display with a touch panel is adopted as a monitor for displaying an image. The number of can be reduced.

  On the other hand, accepting operation input using a touch panel takes longer processing time than accepting operation input using a mechanical operation switch such as a tact switch. The time lag until the process is executed is relatively long. Therefore, a specific operation input (for example, a door phone child, for example) is considered in consideration of a case where the feeling of use for the user is reduced when the time lag is long, such as an operation input for responding to a call from the door phone child device. For example, an operation input for responding to a call from a device may be performed using a mechanical operation switch and an operation button. In addition, when there are a plurality of types of such specific operation inputs, in order to share the mechanical operation switches and the operation buttons with the plurality of types of operation inputs, the functions of the operation switches and the operation buttons (contents of the operation inputs) ) May be displayed on the screen of the liquid crystal display. That is, when the operation switch is operated while a character or icon corresponding to the function “A” is displayed on the screen, an operation input corresponding to the function “A” is accepted, and the function “B” When the operation switch is operated while a character or icon corresponding to is displayed on the screen, an operation input corresponding to the function “B” is accepted. If a mechanical operation switch and a touch panel are used in combination, it is possible to prevent a large number of operation button images from being simultaneously displayed for the touch panel and making it difficult to see the video of the visitor.

1 is a system configuration diagram showing an embodiment of the present invention and a block diagram of an intercom master unit. FIG. It is a front view of the intercom main unit same as the above. (A), (b) is explanatory drawing of the screen display of the liquid crystal display in the interphone main unit same as the above.

  Hereinafter, an embodiment in which the technical idea of the present invention is applied to an intercom system for a detached house will be described in detail with reference to the drawings.

  As shown in FIG. 1, the interphone system of the present embodiment includes an interphone master unit M and an interphone sub-master unit M ′ installed in the house, an interphone slave unit S installed outside the house (for example, an outside entrance), An electric lock device L is provided that locks and unlocks the electric lock installed on the entrance door in response to a control signal from the interphone master unit M. In the present embodiment, an interphone master unit (hereinafter abbreviated as “master unit”) 1 is an interphone device according to the present invention.

  Although not shown, the doorphone slave unit S is a microphone, a speaker, and a voice signal output from the microphone, which is encoded and digitally modulated in a relatively low frequency band, and is modulated via a signal line Ls. An audio signal processing unit that digitally demodulates and decodes an audio signal and generates sound from a speaker, an imaging device that has a solid-state imaging device such as a CCD or CMOS, and an optical system such as a lens, and an imaging device A video signal transmission unit that encodes a video signal output from the digital signal and digitally modulates the video signal in a frequency band relatively higher than that of the audio signal, and transmits the modulated video signal via the signal line Ls, and outputs from the audio signal processing unit The audio signal to be transmitted and the video signal output from the video signal transmission unit are frequency-multiplexed and transmitted to the signal line Ls. A demultiplexer for separating audio signals transmitted from the main unit M and the sub-main unit M ′ via the main unit M, a paging signal transmitting unit for transmitting a paging signal via the signal line Ls, and a microcomputer as a main component. A control unit that performs operation control, an operation input reception unit that receives an operation input of the call button 101 and outputs an operation signal to the control unit, and a power supply circuit 16 of the base unit M via a signal line Ls as described later. A power supply unit that creates an operating power supply for each unit with power fed from the box, and a box-shaped container 100 that stores these units and is installed on the wall of the exterior entrance.

  The power supply voltage (DC voltage) from the base unit M to the doorphone slave unit S is relative to reduce power consumption of the system when the doorphone slave unit S is not in a call state or a monitor state (described later). In a call state or a monitor state, the state is relatively high. Hereinafter, a state where the power supply voltage is low is referred to as a standby power supply state, and a state where the power supply voltage is high is referred to as an operation power supply state. In the intercom S, when the standby power supply state is set, the microcomputer of the control unit waits for an operation signal to be output from the operation input reception unit in the standby state, and the call button 101 is operated to operate the operation input reception unit. When the operation signal is output from the control unit, the control unit controls the call signal transmission unit to transmit the call signal to the base unit M by lowering the line voltage of the signal line Ls to a voltage lower than the standby power supply state. To do. Then, when the base unit M that has received the calling signal shifts the power supply voltage from the standby power supply state to the operation power supply state, the microcomputer of the control unit returns from the standby state to the normal state, and activates the imaging device and the video signal transmission unit. The video signal is transmitted to the main unit M via the signal line Ls and the audio signal processing unit is activated to enable transmission / reception of the audio signal, that is, a state where a call can be made. In addition, as will be described later, when the power supply voltage is shifted from the standby power supply state to the operation power supply state by accepting an operation input for setting the doorphone slave unit S in the monitor state in the master unit M, the microcomputer of the control unit normally changes from the standby state. After returning to the state, the imaging device and the video signal transmission unit are activated and the video signal is transmitted to the parent device M via the signal line Ls, whereby the image captured by the imaging device of the doorphone slave unit S is monitored by the parent device M. It can be done.

  On the other hand, the base unit M encodes the audio signal output from the microphone 2 and the speaker 3 and the microphone 2 and digitally modulates the audio signal in a relatively low frequency band, and transmits the modulated audio signal via the signal line Ls. A communication circuit 4 that digitally demodulates and decodes the sound and sounds the sound from the speaker 3, a liquid crystal display 5, and a demodulator 6 that digitally demodulates and decodes the modulated video signal transmitted via the signal line Ls; An image processing unit 7 for displaying the video signal demodulated by the demodulating unit 6 on the liquid crystal display 5 and performing image processing for displaying a guidance display and an operation button image, which will be described later, superimposed on the video signal; Memory 8 that stores data such as operation button images and alarm sounds, and voice that reads and expands data such as alarm sounds stored in memory 8 An interface (I) that transmits signals between the control unit 9, the touch panel 10 disposed in front of the screen of the liquid crystal display 5, the operation switch 11 including a mechanical switch such as a tact switch, and the electric lock device L. / F) unit 12, an antenna 13 and a radio circuit 14 for transmitting and receiving a radio signal using radio waves as a medium, a power source unit 15 for generating an operating power source for each unit from a commercial power source AC, and a DC power source generated by the power source unit 15 Is supplied to the door phone slave unit S via the signal line Ls, the control unit 1 that controls each part using the CPU as a main component, and the housing 17 that houses these parts.

  The housing 17 of the base unit M is formed in a flat rectangular box shape as shown in FIG. 2, and the screen 5a of the liquid crystal display 5 is exposed at the upper center of the front surface. In addition, a touch panel 10 is disposed on the screen 5 a of the liquid crystal display 5. Further, an antenna 13 protrudes from the left side surface of the housing 17. Furthermore, an operation button 18 for pressing the operation switch 11 is provided on the upper front of the housing 17 on the right side of the screen 5a.

  Here, although not shown in FIG. 1, the intercom system according to the present embodiment detects fire in the house and transmits fire detection information with a radio signal using radio waves as a medium when a fire is detected. A fire sensor, a security sensor that detects opening / closing of a window, breakage of a window glass, and the like, and transmits abnormality detection information with a radio signal using radio waves as a medium when these abnormalities are detected are also provided. In the base unit M, when the radio signal transmitted from the fire detector or the security sensor is received by the antenna 13 and the radio circuit 14, the control unit 1 controls the audio processing unit 9 to cause the speaker 3 to generate a fire. In addition to sounding a warning sound to notify or a warning sound to notify the invasion of a suspicious person, the image processing unit 7 is controlled to display on the liquid crystal display 5 a mark to notify the occurrence of a fire or the intrusion of a suspicious person.

  Further, a secondary master unit M ′ is connected to the call circuit 4 via a communication line Ld, and the master unit M and the secondary master unit M ′ or the door phone slave unit S and the secondary master unit M are connected via the communication line Ld. Audio and video can be exchanged with '. The secondary master unit M 'basically has the same configuration as that of the master unit M except that the antenna 13 and the radio circuit 14 are not provided, and therefore, detailed illustration and description thereof are omitted.

  As described above, when the call signal transmitted from the doorphone slave unit S is received, the control unit 1 of the base unit M controls the power feeding circuit 16 to change the power supply voltage to the doorphone slave unit S from the standby power supply state to the operation power supply. At the same time, the voice processing unit 9 is controlled to make a ringing tone from the speaker 3. On the other hand, in the doorphone slave unit S, the microcomputer of the control unit returns from the standby state to the normal state, activates the imaging device and the video signal transmission unit, and transmits the video signal to the master unit M via the signal line Ls and also the audio signal. Start the processing unit. In the master unit M, the video signal transmitted from the doorphone slave unit S is demodulated by the demodulator 6 and image-processed as necessary by the image processor 7 to display the video of the visitor H on the liquid crystal display 5 ( (See FIG. 3 (a)). When the resident who hears the ringing tone views the video of the visitor H displayed on the screen 5a of the liquid crystal display 5 and presses the operation button 18, the operation switch 11 is turned on and an operation input for starting a call is made. Is received by the control unit 1. When the control unit 1 accepts an operation input for starting a call, the call unit 4 is activated and a call can be made between the visitor and the resident by exchanging audio signals with the doorphone slave unit S via the signal line Ls. It becomes.

  Here, the control unit 1 of the base unit M displays an image as shown in FIG. 3A on the screen 5a of the liquid crystal display 5 from when the call signal is received to when the operation input for starting the call is received. . That is, the video (visitor H and background) captured by the imaging device of the doorphone slave unit S is displayed on the entire screen 5a, and three types of operation button images B1, B2, and B3 are displayed at the lower end of the screen 5a. In addition, a guidance display “call>” is displayed in the center of the right end of the screen 5a (next to the left of the operation button 18). This guidance display (“call>”) is for informing the user (resident) of the function assigned to the mechanical operation switch 11 in the current situation, and is the situation shown in FIG. In the situation of being called from the door phone slave unit S), an operation input for starting a call is accepted. That is, in the present embodiment, the operation switch 11 and the control unit 1 constitute a first operation input accepting unit.

  The operation button images B1, B2, and B3 each have a shape in which the characters “unlock”, “room call”, and “zoom” are surrounded by a square frame. In the control unit 1 of the base unit M, the position (contact position) where the resident touches the screen 5a is acquired from the touch panel 10, and the contact position is the display position of any one of the operation button images B1 to B3, for example, the operation button image. If it coincides with the display position of B1, an operation input for unlocking the electric lock device L is accepted, and if it coincides with the display position of the operation button image B2, an operation input for calling the secondary master unit M ′ is received. If the display position of the operation button image B3 coincides with the reception, an operation input for enlarging the video imaged by the imaging device is received. When the control unit 1 receives an operation input corresponding to the operation button image B1, the control unit 1 transmits an unlock command from the I / F unit 12 to cause the electric lock device L to unlock the electric lock, and displays the operation button image B2. When a corresponding operation input is received, a call signal is transmitted to the secondary master unit M ′ via the communication line Ld. When an operation input corresponding to the operation button image B3 is received, the image processing unit 7 is controlled to be imaged by the imaging device. The image processing for enlarging a part of the video (for example, the center) to the size of the screen 5a is performed. In other words, in the present embodiment, the touch panel 10 constitutes a contact position detection unit, and the control unit 1 constitutes a second operation input receiving unit.

  On the other hand, after accepting an operation input for starting a call, the control unit 1 of the base unit M displays an image as shown in FIG. 3B on the screen 5 a of the liquid crystal display 5. That is, the video imaged by the imaging device of the doorphone slave unit S is displayed on the entire screen 5a, and four types of operation button images B0, B1, B2, and B3 are superimposed and displayed on the lower end portion of the screen 5a. . The operation button image B0 has a shape in which the characters “record” are surrounded by a square frame. If the contact position acquired from the touch panel 10 matches the display position of the operation button image B0, the control unit 1 of the master unit M accepts an operation input for recording a video imaged by the imaging device, and the operation input Is received, the image processing unit 7 is controlled to compress the video imaged by the imaging device and store it in the memory 8. In the image of FIG. 3B, the guidance display corresponding to the operation switch 11 is not displayed, and no operation input is made in the control unit 1 even if the operation switch 11 (operation button 18) is operated in this situation. Not accepted.

  Here, in a situation where the operation button images B1 to B3 and the guidance display (“call>”) are displayed on the screen 5a at the same time as shown in FIG. That is, there is a possibility that the user (resident) mistakenly touches the position of the guidance display in the screen 5a when performing an operation input for starting a call. Therefore, in the present embodiment, the user (resident) displays the guidance display by making the shape of the operation button images B1 to B3 (square frame and character) different from the shape of the guidance display (character and> symbol). Although the possibility of erroneously recognizing the operation button image is reduced, the possibility that the user (resident) erroneously recognizes the guidance display as the operation button image and touches the position of the guidance display in the screen 5a is not zero. .

  Therefore, in the present embodiment, the contact position detected by the contact position detecting means (touch panel 10) is displayed as at least a guidance display ("call>" in FIG. 3A) on the screen 5a of the display means (liquid crystal display 5). When the second operation input accepting means (control unit 1) matches the area (the area surrounded by the broken line a in FIG. 3A), the operation input corresponding to the guidance display (call in FIG. 3A) Start operation input) is accepted. That is, when a user (resident) who misrecognizes the guidance display as an operation button image touches the operation area, an operation input corresponding to the guidance display, for example, an operation input for starting a call is received by the control unit 1 and serves as a control means. The same process as when the control unit 1 receives an operation input for starting a call by operating the operation button 18 (operation switch 11), in this case, the process for starting a call is executed. Therefore, it is possible to provide an intercom apparatus (interphone master unit M) and an interphone system that are improved in usability as compared with a case where an operation input for starting a call is accepted only by the operation button 18 (operation switch 11).
