KR200334398Y1 - The wireless calling system used as electronic wall clock - Google Patents

Abstract

The present invention wirelessly transmits an outgoing signal having a unique ID code from the transmitter and the transmitter for informing the location of the sender, and after receiving it, process it in the control unit and display the sender's unique number on the indicator so that the number of the transmitter can be known. The present invention relates to a radio calling system that operates for the purpose of a wall clock while the receiver is not receiving data from the transmitter in a radio calling system including the receiver.

Each transmitter modulates the ID registered in advance by the control unit and transmits it wirelessly, and the receiver receives the demodulation and processes it by the control unit to display the ID of the transmitter on the display surface of the receiver to identify the calling transmitter. At the service location, the service can be quickly responded to, and when the reception is waiting, the clock can be operated to provide time information to the people at the installation site to maximize the service.

Description

The wireless calling system used as electronic wall clock

The present invention relates to a wireless call system for businesses using the outgoing signal of the radio frequency combined with a wall clock, and wirelessly capable of promptly recognizing a customer's call at a business that provides services such as various businesses and government offices and providing a faster service to the customer. The present invention relates to a call transmitting / receiving system combining an electronic wall clock and a wireless wireless calling system for a business using frequency outgoing signals.

In the past, many customers have to raise their hands or call the operator loudly in order to receive the service at the place of service. As a result, if the operator does not recognize the call of the customer while damaging the surrounding customers, the customer has to inconvenience the call to the operator repeatedly. In order to cope with this, a radio transceiver has been developed and used since 10 years ago, but there are many places where a clock is provided to inform the time of service, which is not good for the aesthetics of the wall and additional expenses are used.

The present invention is to solve the above-mentioned shortcomings, timely recognition of the call of the customer in a place that provides a variety of services, such as restaurants, restaurants, banks, public offices, and can provide a better service to the customer The purpose of the present invention is to provide a wireless call system for an electronic wall clock / combination business that also functions as an electronic wall clock.

Commercial wall clock combined calling system 10, 20 using a radio frequency transmission signal according to the present invention for achieving the object as described above is provided with a unique ID code for informing the location of the customer from the transmitter 20 One outgoing signal is wirelessly transmitted, and the receiving and converting unit converts it to be processed by the control unit 42 after receiving it, and a control for recognizing and informing the location of the called customer by analyzing the outgoing signal through the circuit. And a position display unit for outputting a signal, a position display unit for outputting a message for notifying a location of a customer called by the control unit, and an audio generation and amplification unit 43 for notifying that information has been received on the display unit. It is done.

Here, the transmitter is installed on a wall, a table, an office, etc. in proximity to the customer for service, and configured to display a unique ID code for indicating the location of the customer, and the location display unit 47 is for informing the location of the customer. A speaker for outputting a predetermined sound and an FMD (16) for visually notifying the position of the customer. The FMD 16 of the display unit is displayed for a preset time when there is information (transmitter ID) transmitted from the transmitter 20, and after the set time has passed, the control unit 42 switches to the clock mode to operate the electronic clock. do.

The function keys of the present system include a volume 12 for adjusting the sound of the speaker, a power switch 11, a group setting switch 14 for adjusting a combination of a transmitter, and a clock mode setting button for setting a clock function (13). ).

According to the present invention, a business that provides various services such as a restaurant, a hotel, a restaurant, and the like can recognize a customer's call in a timely manner without harming other customers, and can provide a better service. A service that informs many people of the time can be done while protecting the beauty of the walls.
