BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention, and the manner of achieving them, will be apparent from and elucidated with reference to the embodiments described hereinafter in conjunction with the accompanying drawings.

The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. To fully disclose the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

Hereinafter, the present invention will be described with reference to the drawings for explaining a signal transmission / reception system and a method according to embodiments of the present invention.

FIG. 1 illustrates an exemplary signal transmission and reception system according to an embodiment of the present invention. FIG. 2 illustrates an exemplary transmitter and receiver according to an exemplary embodiment of the present invention. Referring to FIG.

Referring to FIG. 1, the signal transmission / reception system 10 includes a transmitter 100 and a receiver 200.

The transmitter 100 and the receiver 200 of the signal transmission / reception system 10 are preferably operated in a wireless communication manner.

1, the transmitter 100 includes a signal transmitter 110, a response receiver 120, and a controller 130, as shown in FIG.

The signal transmission unit 110 periodically transmits a range check signal to the receiver 200. [ The range check signal is a signal transmitted from the transmitter 100 to the receiver 200. The range check signal varies in size according to the distance between the transmitter 100 and the receiver 200. [

The response receiver 120 receives a response signal from the receiver 200. In this case, the response signal is preferably a signal indicating whether or not a response to the paging signal transmitted from the signal transmitting unit 110 to the receiver 200 is received.

The controller 130 adjusts the output size of the range check signal transmitted from the signal transmitter 110 to the signal receiver 210 of the receiver 200 according to a preset distance or a distance arbitrarily inputted.

For example, when a store employee greatly adjusts the output size of a range check signal transmitted from the transmitter 100 to the receiver 200, the distance at which the transmitter 100 can transmit the range check signal becomes longer If the output size of the range check signal transmitted from the transmitter 100 to the receiver 200 is small, the distance that the transmitter 100 can transmit the range check signal is shortened.

At this time, the controller 130 adjusts the output size of the range check signal according to a preset distance (e.g., 1m, 2m, 3m ... n) through a dial method to adjust the output size of the range check signal, The output size of the range check signal can be adjusted according to the distance arbitrarily input by the user. The controller 130 may adjust the output size of the range check signal through various methods other than the output size adjustment method of the range check signal.

The control unit 130 may store the output size of the range check signal according to the distance, the identification number of each receiver 200, and the call signal transmission period designated for each receiver 200.

1, the receiver 200 includes a signal receiving unit 210, a response transmitting unit 220, and an alarm unit 230.

The receiver 200 may comprise one or more than one.

The signal receiving unit 210 receives the range check signal from the signal transmitting unit 110. The signal receiving unit 210 receives a paging signal from the signal transmitting unit 110.

If the size of the range check signal received by the signal receiver 210 is less than a predetermined size, the alarm unit 230 generates an emergency alarm so that the receiver 200 moves away from the transmitter 100, Thereby preventing it from being lost.

Also, the alarm unit 230 does not generate an emergency alarm if the range check signal is not received within a preset time after receiving the range check signal of a predetermined size or more.

For example, if the receiver 200 is charged in the transmitter 100 and the power supply of the transmitter 100 is interrupted, the receiver 200 can not receive the range check signal from the transmitter 100 In this case, the alarm unit 230 of the receiver 200 does not judge this case as abnormal and does not generate an emergency alarm by determining it as normal.

In addition, the alarm unit 230 generates a paging signal, which is received by the signal receiving unit 210, as a paging alarm.

At this time, the alarm unit 230 can generate emergency alarms and call alarms by distinguishing various sounds such as voice, bell, and vibration

In addition, the alarm unit 230 generates a response signal indicating whether the paging signal received by the signal receiving unit 210 is received.

The response transmission unit 220 transmits the response signal generated by the alarm unit 230 to the response reception unit 120 of the transmitter 100.

The signal transmitter 110 of the transmitter 100 transmits a call signal including an identification number corresponding to the specific key when a specific key is input to the input device. And compares the identification number included in the received paging signal with a predetermined number stored in advance for each receiver, and generates a paging alarm in the alarm unit 230 of the receiver 200 when they match.

For example, when the signal transmission unit 110 of the transmitter 100 transmits a call signal to a plurality of receivers 200, the signal transmission unit 110 inputs a specific key to the input device, To the respective receivers 200, which include identification counters to identify the receivers. The signal transmitter 110 transmits the identification numbers (e.g., 1, 2, 3 ... n) included in the paging signal and the designated numbers (e.g., R1, R2, ... Rn and compares them to generate a paging alarm at the alarm unit 230 of the receiver 200.

In addition, the signal transmitter 110 transmits the paging signal to each receiver 20, transmits the paging signal at a random period, stops the transmission of the paging signal when a response signal is received, and the alarm unit 230, The receiver 200 compares the identification number included in the received paging signal with a predetermined number stored in advance for each receiver 200 to generate a response signal for the paging signal, And transmits the generated response signal to the transmitter 100.

For example, when the signal transmitter 110 of the transmitter 100 transmits a paging signal to the signal receiver 210 of each receiver 200, the transmitter 100 uses the same frequency (or short channel) There is a problem that an interference occurs in a paging signal transmitted from the transmitter 100 to each receiver 100 or a paging signal is not transmitted to the receiver 200 when the paging signal is transmitted to each receiver 200. [

In addition, when the receiver 200 generates a response signal and transmits the response signal to the transmitter 100, when each receiver 200 transmits a response signal to the transmitter 100 using the same frequency (or short channel) There is a problem that interference occurs in a response signal transmitted from each receiver 200 to the transmitter 100 or a response signal is not transmitted to the transmitter 100. [

Therefore, in order to prevent such a problem, the signal transmitter 110 of the transmitter 200 transmits the paging signal to the signal receiver 210 of each receiver 200 at a random period. In addition, the signal transmitter 110 may transmit a paging signal to the receiver 200 at random intervals, using different frequencies (or multiple channels), or with different transmission times to prevent interference and loss of signals .

At this time, when the transmission signal unit 110 of the transmitter 100 transmits a paging signal to the signal receiving unit 210 of the receiver 200, the alarm unit 230 of the receiver 200 receives the paging signal (For example, R1, R2, R3 ... Rn) previously stored for each receiver 200 and the identification numbers (for example, 1, 2, 3 ... n) And generates a response signal to the paging signal. The receiver 200 may transmit a response signal from the response transmitter 220 to the response receiver 120 of the transmitter 100 when a response signal is generated in the alarm unit 230. Here, when a response signal is received in the response receiver 120 of the transmitter 100, the transmitter 100 stops transmitting a paging signal to be transmitted to the receiver 200, . ≪ / RTI >

3 is a flowchart illustrating a method of transmitting and receiving a range check signal according to an embodiment of the present invention.

3, the signal transmitting unit 110 of the transmitter 200 periodically transmits a range check signal to the signal receiving unit 210 of the receiver 200 (Step S110).

Then, the signal receiving unit 210 of the receiver 200 receives the range check signal from the signal transmitting unit 110 (step S120).

Then, the alarm unit 230 of the receiver 200 determines whether the range check signal received by the signal receiver 210 is abnormal (step S130).

At this time, if the size of the range check signal received in the signal receiving unit 210 is less than a preset size, the range check signal is determined as an abnormal signal and the alarm unit 230 generates an emergency alarm (step S140).

On the other hand, when the size of the received range check signal is equal to or larger than a predetermined size, an emergency alarm is not generated. If the receiver 200 does not receive the range check signal within a predetermined time after receiving the range check signal of a predetermined size or larger from the transmitter 100, the receiver 200 transmits the range check signal Is determined as a normal signal and does not generate an alarm.

4 is a flowchart illustrating a method for transmitting and receiving a paging signal according to an embodiment of the present invention.

4, the signal transmitting unit 110 of the transmitter 200 first transmits a paging signal to the signal receiving unit 210 of the receiver 200 (step S210).

Then, the signal receiving unit 210 of the receiver 200 receives the paging signal from the signal transmitting unit 110 (step S220).

Next, the alarm unit 230 of the receiver 200 compares the call signal received by the signal receiver 210 with a designated number preset for each receiver 200 (step S230).

The alarm unit 230 of the receiver 200 receives an identification number (e.g., 1, 2, 3, ..., n) included in the received call signal and a predetermined number : R1, R2, R3 ... Rn), and generates a call alarm when they match (step S240).

Then, the alarm unit 230 generates a response signal to the paging signal, and the response transmission unit 220 transmits a response signal to the response reception unit 120 of the transmitter 100 (step S250).

Then, when the response receiver 120 of the transmitter 100 receives the response signal from the receiver 200, it stops transmitting the call signal (step S260).

Then, the receiver 200 does not generate a paging alarm at the alarm unit 230 of the receiver 200 (step S270) if a paging signal is not received from the transmitter 100. FIG.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
