DE202008016438U1 - Electronic device for the automatic acoustic welcome and farewell of visitors of buildings (sales areas) in one device, possibly with external notification of entering into other rooms - Google Patents

Abstract

Electronic device for automatic acoustic greeting (acoustic welcome text or reference to specific circumstances or special promotions) and which when leaving a farewell or Acknowledgment text by means of two electronically stored digital texts possibly also with music of visitors to buildings or retail space, characterized in that the device In a device between entering and the object leaving people can distinguish and depending on the direction various texts acoustically reproduced.

Description

To the The state of the art is dealt with under points 0008 to 0010.

Device with the following features.

at Detecting a movement towards the entrance but behind the entrance The building is accompanied by an acoustic welcome message or reference to specific circumstances or promotions and when leaving a farewell or thanksgiving text by means of two electronically stored digital texts possibly also with Music, which are changeable.

The Device allows the welcome and Approval by means of a device.

The two directional sensors (motion sensors) ( 1 ) are directed approximately 90 degrees to each other obliquely toward the ground and deep the motion pulse which of an amplifier circuit / filtering ( 2 ) and to the optocoupler ( 3 ) for activating the digital sound module associated with the movement ( 4 ) is forwarded. This pulse is indicated by a light emitting diode (LED). Likewise, this motion impulse of ( 2 ) a timer ( 5 ), which has a kind of feedback ( 11 ) both amplifier circuits ( 2 ) Locks a certain freely adjustable time to prevent false activations and multiple activations with several briefly detected movements. The activation of the locking and holding the lock during the lock time is signaled by a light emitting diode (LED).

When activating a sound module ( 4 ) is also simultaneously via a transistor stage (T) of the NF amplifier ( 7 ), which amplifies the sound signal with the stored text or music and to the loudspeaker ( 8th ). For each direction there is a separate circuit, the amplifier ( 7 ), Power supply ( 9 ) and the speaker ( 8th ) respectively. ( 8a switchable) is used by both directional circuits.

The sound modules each have their own microphone ( 6 ) with the help of the text or music can be stored. The memory contents are also retained in the absence of power.

In order to switch the device on and off during the operating times (opening times), an upstream circuit of a timer ( 10 ) in front of the power supply ( 9 ) of the device possible.

The motion sensors ( 1 ) are directed approximately 90 degrees against each other diagonally towards the ground. It is also possible instead of the motion sensors ( 1 ) the device to an electric door opening system ( 12 ) to couple with the two motion sensors contained therein, so that when you open the door from the outside of the Bergrüßungstext and door opening from inside the adoption or Thanksgiving text is done.

In order to prevent visitors from entering or even leaving the room in other rooms (office, warehouse or similar) acoustically (or optically possible, also wirelessly via radio ( 14 )) can be a switchable speaker ( 8a ) are installed. It is also possible the output of the optocoupler ( 3 ) for the entry and by means of an activated by this transmission circuit ( 13 ) report the message via Piper or similar to the reception staff.

The Device can also be used as visitor detector (bell) be used.

The Device becomes over the entrance but room side (inside) Installed.

State of the art

It there already exists a device called a pass-through detector, which only works in one direction and sideways beside the Entrance can be attached and when entering the room one Text activated, but also when leaving the room the same Text activates what is perceived as not optimal and thoughtful.

There is already a doormat with voice output (speech mat) DE 20108002U1 which emits these acoustic signals or text when loaded by a person. Another disadvantage is the usability in one direction and the mechanical wear of the mat and its sensor (reduced durability). Likewise, the power supply may prove difficult (cables on the floor).

It exist a multiplicity of visitor alarm systems (shop bell), which different sounds (melodies) and by door contact or motion sensors are controlled.
