An object of the present invention is to provide an interphone in which a contactless card reader is built in the interphone.
A contactless card reader is built in an interphone.

Description

Detailed description of the invention

  The present invention relates to an interphone used for a gate opening / closing unlocking monitoring system.

Conventionally, for example, Japanese Patent Application Laid-Open No. 2005-21595 has proposed a school building security system that can ensure safety in a school with a simple configuration, and this security system is provided with a monitoring facility provided at a gate serving as an entrance to a school and a predetermined facility in the school. A centralized monitoring facility provided at a position, the monitoring facility includes an interphone with a surveillance camera and an electric lock that can be locked and unlocked, and the centralized surveillance facility includes a display and an interphone device that display images taken by the surveillance camera Speaker, microphone, and storage server that stores images taken by the camera, and a remote open / close switch that remotely locks and unlocks the electric lock. Information on the storage server can be viewed from an external computer via the Internet. The school building security system is described.

  As described in [0015] of the above publication, the interphone according to the present invention can be used as an external switch for an electric lock even if an ID card, a card key, or the like necessary for a visitor to school to open the electric lock. Alternatively, the key portion may be constituted by a numeric keypad and locked / unlocked by pressing a predetermined number. Further, it is described that a fingerprint collation type may be used.

  However, the locking / unlocking part that can be placed at the gate such as a double door is particularly susceptible to an impact at the time of opening and closing, and the switch (sensing switch) of such a card may be damaged by the impact.

  In addition, since the card reader is located at the gate and away from the interphone, the unlocking operation using the card and the conversation with the manager using the interphone cannot be performed simultaneously.

Problems that the device tries to solve

  It is a technical problem to provide an interphone in which a contactless card reader is built in an interphone.

Means to solve the problem

  The invention of claim 1 provides an interphone incorporating a contactless card reader.

  In this device, when the impact at the time of opening and closing is applied to the locking / unlocking part, such a switch (sensing switch) such as a card is not likely to be damaged by the impact, and the card reader position is on the interphone. The unlocking operation using the card and the conversation with the manager using the interphone can be performed simultaneously.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view of an interphone 1 according to the present invention. The interphone 1 includes a non-contact card reader 2 microphone 3, a speaker 4, a call button 5, and an operation lamp 6 on the front.

  FIG. 2 shows a gate opening / closing unlocking monitoring system, wherein an electromagnetic electric lock 7 is provided on the gate A, and an interphone 1 is provided outside the gate pillar 8. A monitoring camera 9 is installed at a position for monitoring the vicinity of the gate A.

  Reference numeral 11 denotes a plurality of monitoring facilities provided in the school building, which will be described in detail with reference to FIG. 3. The monitoring facility 11 includes a monitor TV 12 that displays the image of the monitoring camera 9, an unlock button 16, a continuous gate button 17, and a buzzer stop button 18. An unlocking display lamp 20, an opening display lamp 21, a closing display lamp 22, a continuous opening display lamp 23, and the like are provided.

  FIG. 3 is a system diagram of the gate opening / closing unlocking monitoring system. The interphone 1 with a built-in non-contact card reader unlocks the electromagnetic electric key 7 with a non-contact card. The relay BOX 8 incorporates an unlock button 24 so that the electromagnetic electric key 7 can be unlocked from the inside.

  The surveillance camera 9 projects the situation around the gate on the monitor television 12 as an image. The gate sensor 10 changes the relay board 15 by opening and closing the gate and turns on the lamp of the gate display 21. The monitor TV 12 captures the video from the surveillance camera 9. The power supply device 13 supplies power to the surveillance camera 9, the contactless card reader built-in interphone 1, the electromagnetic electric key 7 timer board 14, the relay board 15 and the like.

  The timer board 14 sets a buzzer imlag. The relay board 15 controls each operation of the unlocking button 16, the continuous opening button 17, the buzzer stop button 18, the buzzer 19, the unlocking display 20, the opening display 21, the closing display 22, the continuous opening display 23, and the like. The interphone master unit 25 can communicate with the interphone 1 with built-in contactless card reader.

Effect of device

  As described above, the present invention provides an interphone with a built-in non-contact card reader, and the card switch (sensing switch) may be damaged by the impact when the locking / unlocking part is subjected to an impact during opening and closing. In addition, since the card reader is located at the interphone, there is an effect that the unlocking operation by the card and the conversation with the administrator by the interphone can be performed simultaneously.
