That is, the present invention separately includes an alarm device (vibration and buzzer) that generates vibrations at different vibration cycles between the incoming state and the lost state of the mobile radiotelephone and the battery low state when receiving the incoming signal of the portable wireless mobile phone. The vibration generating signal transmission device for driving the vibration device is configured by mounting as a module inside the battery pack or a portable mobile wireless telephone.

In recent years, with the development of electronic / semiconductor technology and communication technology, consumer demand, and business competition between mobile phone manufacturers and mobile communication providers, development of various low cost, high quality and high performance portable mobile phones has been progressing remarkably. It is true.

Hereinafter, a reception alarm device of a portable mobile radio telephone according to the prior art will be described with reference to the accompanying drawings.

1 is a schematic block diagram of a portable radiotelephone according to the prior art. Referring to FIG. 1, the receiver 10 receives an incoming signal of a portable mobile radiotelephone through an antenna ANT. And, the incoming signal detection unit 20 for detecting whether the incoming signal received from the receiving unit 10 is the incoming signal of the portable mobile radio telephone, and when the incoming signal is detected vibration or bell (melody sound including a buzzer) Mode selection unit 30 is configured to select the vibration mode and the bell mode to notify the incoming call.

In addition, the storage unit 50 storing a plurality of different audio data corresponding to the bell mode, and the signal output from the incoming signal detection unit 20 is detected as the incoming signal of the corresponding portable mobile radio telephone and the mode selection If the mode selected in the unit 30 is a bell mode, one arbitrary audio data stored in the storage unit 50 is read and output, and if the mode selected in the mode selector 30 is a vibration mode, a vibration generation control signal is output. The control part 40 which outputs is comprised.

In addition, the sound generating unit 60 for generating audio sound corresponding to the audio data output from the control unit 40, and the vibration generating unit 70 for generating vibration in accordance with the vibration generating control signal output from the control unit 40 It consists of.

The operation of the alarm device upon reception of the portable mobile radio telephone according to the prior art having such a configuration will be described.

First, when the other party, that is, the caller makes a call and transmits a call signal, the signal is received by the receiving unit 10 through the antenna ANT of the portable mobile radio telephone and then outputs to the incoming signal detecting unit 20.

When the incoming signal detection unit 20 detects whether the call signal (frequency) output from the receiver 10 is the incoming signal signal of the portable mobile radio telephone, the received call signal is the incoming signal of the portable mobile radio telephone. The high signal is transmitted to the control unit 40, and when it is not an incoming signal of the portable mobile radio telephone, the low signal is applied to the control unit 40. In this case, the incoming signal is detected by detecting the ID carried on the carrier frequency received from the receiver 10 and comparing it with a preset unique ID.

If the signal output from the incoming signal detection unit 20 is a low signal, the controller 40 determines that it is not an incoming signal of the portable mobile radio telephone and does not perform any operation, and on the contrary, outputs from the incoming signal detection unit 20. If the signal is a high signal, it is determined that the incoming signal of the portable mobile radio telephone. At this time, the control unit 40 determines whether the mode selected by the mode selection unit 30 is a vibration mode or a bell mode. If the mode selected by the user is the vibration mode, the control unit 40 includes a vibration generating unit ( 70) by outputting a vibration generating control signal to generate a vibration, it is to inform the user that the call is received. Here, the vibration generating unit 7 () is a vibration motor.

However, when the mode selected by the user is a bell mode instead of the vibration mode, the controller 40 reads one audio data (melody data) selected by the user from among a plurality of audio data stored in the storage 50 and generates a sound generator ( 60), the selected melody sound is generated. Here, the sound generator 60 includes an amplifier and a speaker, and the controller 40 includes an A / D converter for converting audio data read from the storage unit 50 into an analog signal. Since the detailed configuration is the same as the configuration and method of the general audio reproducing apparatus, the illustration and detailed description of the drawings are omitted.

However, when the vibration mode is selected, the portable mobile cordless phone is not in close contact with the human body, i.e., the mobile phone is placed at a certain distance, for example, when the portable phone is placed in a bag or deeply worn like a jumper. In the state, there is a problem that the user cannot easily determine this even though the call signal is received and the vibration is generated.

In addition, when the portable mobile radio is placed at a certain distance with the mode selected as the bell mode, a call signal is received and a random ring tone (melody) may not be heard by the user depending on the surrounding conditions. There are also other problems that occur frequently.

In addition, since all functions are built in the portable mobile radiotelephone and there is no separate loss prevention function, there is a big problem of loss of the portable mobile radiotelephone.

In addition, to some extent, the voltage charged in the battery supplying power to the portable mobile radiotelephone is discharged. To check the state of charge, that is, the amount of charge, the user displays the battery displayed on the liquid crystal display of the portable radiotelephone. There is a troublesome problem of checking the filling amount.

Hereinafter, with reference to the accompanying drawings a preferred embodiment of the alarm device and method of a portable mobile radio telephone according to the present invention will be described in detail.

Figure 2 is a perspective view of the alarm device of the portable mobile radio telephone according to the present invention, Figure 3 is a view showing a detailed block circuit configuration of the alarm device of the portable mobile radio telephone according to the present invention, with reference to Figs. Looking at the configuration of the present invention, the same as the configuration of the mobile mobile phone 100 and the mobile mobile phone 100, the power supply to the mobile phone 100, and informs when the incoming signal is received through the portable wireless phone 100 A battery pack 200 having a built-in transmission device (not shown) for transmitting a vibration for generating a vibration, a vibration for preventing a loss of a phone, and a vibration for notifying a low battery state, and a battery pack 200. It comprises a portable vibration device 300 for receiving the vibration generating signal transmitted from the transmitting device within) and generates vibrations of different periods according to the received vibration generating signal. Here, the transmission device may be mounted inside the battery pack 200 or may be mounted as a module inside the portable mobile radio telephone 100.

This configuration will be described in detail with reference to FIG. 3 (the embodiment in which the transmitter is built in the battery pack). First, the portable mobile radio telephone 100 uses the antenna ANT and the receiver 10 shown in FIG. When the incoming signal is received, the incoming signal detection unit 110 is configured to detect whether the received incoming signal is the incoming signal for the portable mobile radio telephone 100 and output a high or low signal according to the detection result.

The battery pack 200 includes a power supply unit 210 for supplying power to a portable mobile radio telephone 100 and a transmission device inside the battery pack 200, and a portable radio telephone 100 (battery pack) when power is supplied. Generating a primary ID signal for preventing loss, and generating a dependent ID signal for generating incoming vibration in accordance with the incoming signal output from the first incoming signal detection unit 110 of the portable mobile radio telephone 100. A controller 220 which detects a voltage of the supply unit 210 and generates and outputs another dependent ID signal according to the detected voltage, a carrier signal generator 230 which generates a carrier signal when power is supplied, and a controller A carrier signal including a synthesizer 240 for synthesizing each of the ID signals output from the 220 with a carrier signal generated from the carrier signal generator 230, and a carrier signal including each of the ID signals output from the combiner 240. Carrier which transmits wirelessly It consists of a transmitter (250). Here, the controller 220, when the power is supplied from the power supply unit 210, the main ID generating unit 221 for generating a main ID signal for preventing the loss, and the first incoming signal detection unit of the portable mobile radio telephone 100 When the incoming signal is detected by the second incoming signal detection unit 222 and the second incoming signal detection unit 222 that detects the high / low output signal according to the incoming signal detection output from the 110, The first subordinate ID generating unit 224 generates a first subordinate ID information signal for notifying that the incoming call has been received, and the voltage detecting unit outputs a detected voltage detection signal by detecting a voltage for the power supplied from the power supply unit 210. And a second dependent ID information signal indicating a low battery state when the detected voltage is lower than the preset reference voltage by comparing the voltage detection signal output from the voltage detector 223 with the preset reference voltage. 2 dependent ID generation unit 220 It is sex. In this case, the primary ID is a syncronous signal, and the first and second IDs are different coding signals.

And, as shown in Figure 3, the vibration device 300 is a carrier signal receiver 310 for receiving a carrier signal containing each ID signal transmitted from the carrier signal transmitter 250 in the battery pack 200, and the carrier The ID detector 320 detects only each ID signal from the carrier signal received by the signal receiver 310, and the comparator 330 compares each ID signal detected by the ID detector 320 with a predetermined reference ID signal. ) And a vibration control unit 340 for selectively outputting a vibration generation control signal for generating vibrations having different periods according to the signal output from the comparison unit 330, and the vibration control unit 340. It consists of a vibration generating unit 350 for generating a vibration having a period corresponding to the vibration generating control signal output from. Here, the ID detecting unit 30 may include a main ID detecting unit 321 for detecting only the main ID from the carrier signal received by the carrier signal receiving unit 310, and only a first dependent ID from the carrier signal received from the carrier signal receiving unit 310. The first slave ID detector 322 detects the second slave ID detector 321 that detects only the second slave ID from the carrier signal received by the carrier signal receiver 310. The comparison unit 330 compares a main ID detected by the main ID detector 321 with a preset reference main ID, and a first ID detected by the first dependent ID detector 322. The first subordinate ID comparison unit 332 for comparing the subordinate ID with the preset reference first subordinate ID, and the first subordinate ID detected by the second subordinate ID detection unit 323 and the preset reference first subordinate ID are compared. The first subordinate ID comparison unit 333 is configured.

The operation of the alarm device (an embodiment in which the transmission device is mounted inside the battery pack) of the portable mobile radio telephone according to the present invention having such a configuration will be described.

First, when the battery pack 200 is connected to the portable mobile radio telephone 100 and power is supplied from the power supply unit 210 to each device, the main ID generating unit 211 generates a continuous main ID at a predetermined time interval. Is output to the synthesis unit 240. Here, the main ID is a sync signal.

In addition, when the incoming signal is output from the first incoming signal detection unit 110 of the portable mobile radio telephone 100, the second incoming signal detection unit 212 detects the incoming signal, and when the incoming signal is detected, the detection signal is output to the first signal. The subordinate ID generator 224 outputs the subordinate ID generator 224 to generate the first subordinate ID and output the subordinate ID generator 224 to the synthesizer 240.

At the same time, the voltage detector 223 detects a voltage of the power output from the power supply 210 to detect a low battery state. That is, when the detected voltage value is less than the preset reference voltage value by comparing the detected voltage value with the preset reference voltage value, it is determined as a low battery state and outputs the corresponding signal to the second dependent ID generator 220. Accordingly, the second dependent ID generator 220 generates the second dependent ID according to the signal provided from the voltage detector 223 and outputs the second dependent ID to the combiner 240.

Therefore, the combiner 240 synthesizes the input ID signal and the carrier signal generated by the carrier signal generator 230 and transmits the synthesized signal to the vibrator 300 through the carrier signal transmitter 250.

For example, when the incoming signal is not detected by the second incoming signal detector 222 and the voltage value detected by the voltage detector 223 is greater than the preset reference voltage, the first and second dependent ID signals are not generated. Therefore, only the main ID signal generated by the main ID generator 221 is applied to the combiner 240, synthesized with the carrier signal generated by the carrier signal generator 230, and vibrated through the carrier signal transmitter 250 ( 300). Here, since the main ID signal is continuously generated at a predetermined time interval, the main ID signal is synthesized with the carrier signal and continuously transmitted to the vibrator 300 at a predetermined time interval.

The carrier signal transmitted as described above is received by the carrier signal receiver 310 of the vibrator 300, and the carrier signal including the received main ID signal is output to each of the ID detectors 321, 322, and 333. In this case, the first and second subordinate ID detection units 322 and 333 do not detect the first and second subordinate IDs, and only the operation of the main ID detection unit 321 is performed. That is, only the main ID signal included in the carrier signal is detected.

The detected main ID from which the main ID is detected is output to the main ID comparing unit 331 and compared with the preset reference main ID. When the comparison results are identical, the vibration control unit 340 transmits a corresponding signal to the main ID comparison unit 331. When the output signal is input from the main ID comparison unit 331, the vibration controller 340 determines that the portable mobile radio telephone 100 is located within a predetermined distance from the vibration device 300, and generates the vibration unit 350. It is to keep the vibration free state without driving).

However, even if the carrier signal including only the main ID is transmitted from the transmitter installed in the battery pack 200 or the portable mobile radio telephone 100 as a module, the first and second subordinate ID detection units 322 and 323 as well as the main ID are transmitted. ), There may be a case where the first and second subordinate IDs are respectively detected. If the first and second subordinate IDs are detected, the detected first and second subordinate IDs are compared with the reference ID values preset by the first and second subordinate ID comparison units 332 and 333, respectively. In this case, when the detected first and second subordinate IDs are different from the preset reference ID values, it is determined that the first and second subordinate IDs do not correspond to the first and second subordinate IDs.

On the other hand, although the main ID signal and the carrier signal synthesized from the transmission device mounted as a module in the battery pack 200 or the portable mobile radio telephone 100 continuously transmitted to the vibration device 300 at a predetermined time interval, If at least one main ID is not detected by the main ID detecting unit 321 for a predetermined time, the vibration controller 340 determines that the portable mobile radio telephone is located at a predetermined distance or more, and may cause loss of vibration having a predetermined period. The control signal is applied to the vibration generator 350 to control the vibration (first vibration mode).

Here, when only the power is applied, the main ID is generated at a predetermined time interval, synthesized with the carrier signal, transmitted to the vibrator 300 to receive the corresponding main ID signal. Since the distance to the user wearing 300 is located within a certain distance, it is determined that there is no fear of loss of the portable mobile radiotelephone and does not generate vibration (non-vibration mode), on the contrary, the vibration device 300 receives the main ID signal. If it is not detected at least once within a certain time, the distance between the portable mobile telephone and the user, that is, the user wearing the vibrating device, is determined to be separated by a certain distance or more and has a predetermined period of vibration (first vibration mode). By generating a warning to generate a vibration for the user to prevent loss of the portable mobile radio telephone (100). Here, the main ID is not detected can be divided into three categories.

First, when the carrier signal is not received. Second, when the carrier signal is received but there is no main ID signal in the carrier signal. Third, when the carrier signal is received, the main ID signal included in the carrier signal is different from the preset main ID. In case of ID. In this case, when the carrier signal is received but the main ID is different, the carrier signal is a carrier signal transmitted from another portable mobile radio telephone having the same frequency as the carrier signal transmitted from the portable mobile radio telephone 100.

As such, the second incoming signal detection unit is in communication with the transmission device and the vibration device mounted as a module in the battery pack 200 or the portable mobile radio telephone 100 to prevent loss of the portable mobile radio telephone 100. When the incoming signal from the first incoming signal detection unit 110 of the portable mobile radio telephone 100 is detected at 212 and the detected voltage of the battery at the voltage detection unit 223 is equal to or greater than the preset reference voltage value, The second subordinate ID generating unit 225 does not generate the second subordinate ID, and only the first subordinate ID generating unit 224 generates the first subordinate ID and inputs the synthesized unit 240.

Accordingly, the combiner 240 may generate the first slave ID generated by the first slave ID generator 224 and the primary ID signal generated by the primary ID generator 221 to generate a carrier signal generated by the carrier signal generator 230. And synthesized and transmitted to the vibrator 300 through the carrier signal transmitter 250.

In this case, the reason for synthesizing the main ID signals together and transmitting them is that the main ID signals continue to be generated at regular time intervals when only the power is supplied.

The carrier signal including the main ID signal and the first slave ID signal transmitted as described above is received by the carrier signal receiver 310 of the vibration device 300, and the carrier signal including the received main ID and the first slave ID signal is Each ID detection unit 321, 322, 333 is applied.

Therefore, each ID detection unit 323, that is, the main ID detection unit 321 detects only the main ID signal included in the carrier signal and outputs it to the main ID comparison unit 331, and the first dependent ID detection unit 322 transmits the carrier signal. Only the first dependent ID signal included in the signal is detected and output to the first dependent ID comparison unit 332. In this case, since the second subordinate ID is not transmitted, the second subordinate ID detection unit 323 does not detect the second subordinate ID signal.

Subsequently, the main ID comparing unit 331 and the first subordinate ID comparing unit 332 compare the detected main ID and the first subordinate ID with the preconfigured main ID and the first subordinate ID to determine whether they are the same ID signals. Will be judged.

As a result of the determination, when the detected main ID is the same as the preset main ID and the detected first dependent ID is the same as the preset reference first dependent ID, the vibration controller 340 may notify the user that the call is received. The vibration generating control signal for generating a vibration having a period different from the vibration period of the first vibration mode for preventing the loss of a portable mobile radio telephone 100 is output to the vibration generating unit 350. Therefore, the vibration generator 350 generates a vibration at a cycle corresponding to the vibration generation control signal provided from the vibration controller 340 to inform the user that the call is received (second vibration mode).

However, when the primary ID is not detected by the ID detector 320, that is, when the portable mobile radio telephone 100 is separated from the vibrator 300 by a predetermined distance or more and the primary ID signal is not detected, the first subordinate ID is detected. Again, it will not be detected. Here, the main ID is not detected when the carrier signal is not received and when the carrier signal is received but the main ID is not detected. Here, the received carrier signal is a carrier frequency other than the carrier signal transmitted from the corresponding portable mobile radio telephone 100 with the same frequency.

As such, when the carrier signal is not received for a predetermined time or the carrier signal is received but the main ID is not detected at least once for a predetermined time, the vibration device 300 in the vibration controller 340 is a portable mobile radio telephone 100. It is determined that the distance from the predetermined distance from the vibration generating unit 350 to generate the vibration in the first vibration mode as described above. That is, the vibration for preventing the loss of the portable mobile radio telephone 100.

Meanwhile, the voltage detector 223 continuously checks the low battery state by detecting the voltage of the battery while performing the above operation.

As a result, when the battery voltage is lower than the preset reference voltage and the incoming signal is not detected by the second incoming signal detector 222, the second dependent ID generator 225 generates a second dependent ID to generate the synthesizer 240. Will output At this time as well, the main ID generating unit 221 generates a main ID and outputs it to the combining unit 240.

The combiner 240 synthesizes the input main ID signal and the second dependent ID signal with the carrier signal generated by the carrier signal generator 230 and transmits them through the carrier signal transmitter 250.

The carrier signal including the main ID signal and the second dependent ID signal transmitted in this way is received by the carrier signal receiver 310 of the vibration device 300, and the carrier signal including the received main ID and the second dependent ID signal is Each ID detection unit 321, 322, 333 is applied.

Accordingly, each ID detection unit 323, that is, the main ID detection unit 321 detects only the main ID signal included in the carrier signal and outputs it to the main ID comparison unit 331, and the second dependent ID detection unit 323 transmits the carrier signal. Only the second dependent ID signal included in the signal is detected and output to the second dependent ID comparison unit 333. In this case, since the first dependent ID is not transmitted, the first dependent ID detection unit 322 does not detect the first dependent ID signal.

Subsequently, the main ID comparison unit 331 and the second subordinate ID comparison unit 333 compare the detected main ID and the second subordinate ID with the preconfigured main ID and the second subordinate ID to determine whether they are the same ID signals. Will be judged.

As a result of the determination, when the detected main ID is the same as the preset main ID, and the detected second dependent ID is the same as the preset reference second dependent ID, the vibration controller 340 is currently connected to the portable mobile radio telephone 100. In order to notify the user that the voltage of the battery supplying power is a low battery state, the vibration period of the first vibration mode for preventing the loss of the portable mobile radio telephone 100 described above, and the second vibration mode for notifying that the call is received. The vibration generation control signal for generating vibration in the third vibration mode having a period different from the vibration period is to be output to the vibration generator 350. Therefore, the vibration generator 350 generates a vibration having a period of the third vibration mode corresponding to the vibration generation control signal provided from the vibration controller 340 to inform the user that the current battery state is a low battery state. .

However, when the main ID is not detected by the ID detecting unit 320, that is, when the portable mobile radio telephone 100 is separated from the vibrator 300 by a predetermined distance or more, the main ID signal is not detected and the carrier signal is received. If not, the second dependent ID is also not detected. Therefore, when the main ID corresponding to the portable mobile radio telephone is not detected by the vibrator 300 for a predetermined time, it is determined that the portable mobile radio telephone 100 is separated from the vibrator 300 by a predetermined distance or more. The vibration controller 340 controls the vibration generator 350 to generate vibration in a first vibration mode for preventing loss.

Meanwhile, the case where the incoming signal is detected and the detected voltage is below the preset reference voltage will be described.

First, when the incoming signal is detected by the second incoming signal detector 222 and the voltage detected by the voltage detector 223 is less than or equal to the preset reference voltage, the first and second dependent ID generators 224 and 225 are detected. In FIG. 1, first and second dependent IDs are generated and output to the combining unit 240, respectively. At this time, the main ID generating unit 211 also generates a main ID and outputs it to the combining unit 240. Accordingly, the combiner 240 synthesizes the input primary ID and first and second dependent ID signals with the carrier signal generated by the carrier signal generator 230 to the vibrator 300 through the carrier signal transmitter 250. Will be sent.

The carrier signal including the primary ID and the first and second dependent ID signals transmitted in this way is received by the carrier signal receiver 310 of the vibration device 300 and includes the received primary ID and the first and second dependent ID signals. The carrier signal is applied to each ID detection unit 321, 322, 333.

Accordingly, each ID detecting unit 323, that is, the main ID detecting unit 321 detects only the main ID signal included in the carrier signal and outputs the same to the main ID comparing unit 331, and the first dependent ID detecting unit 322 transmits the carrier signal. Only the first dependent ID signal included in the signal is detected and output to the first dependent ID comparison unit 332. In addition, the second subordinate ID detecting unit 323 detects the second subordinate ID signal included in the carrier signal and outputs the second subordinate ID comparing unit 333.

Subsequently, in the main ID comparison unit 331 and the first and second subordinate ID comparison units 332 and 333, the detected main ID and the first and second subordinate IDs are set in advance. The comparison is performed to determine whether the ID signals are the same.

As a result of the determination, when the detected main ID is the same as the preset main ID and the detected first and second dependent IDs are the same as the preset reference first and second dependent IDs, the vibration controller 340 is configured to receive the current call. At the same time, it is determined that the voltage of the battery currently supplying power to the portable mobile radio telephone 100 is in a low battery state to notify the user of the first, the vibration generating unit 350 in a second vibration mode for notifying that the call is received. After a predetermined time, or when the user turns on the phone, the vibration generator 350 is sequentially switched to a third vibration mode for notifying that the battery power of the portable mobile wireless telephone 100 is low. Will be driven. That is, when the main ID and the first and second dependent IDs are detected at the same time, after driving the vibration generator 350 in the second vibration mode corresponding to the first dependent ID according to the priority, the third vibration is thus performed. The vibration generating unit 350 is driven in the mode.

However, when the main ID is not detected by the ID detecting unit 320, that is, the portable mobile radio telephone 100 is separated from the vibrator 300 by a predetermined distance or more, the main ID signal is not detected at least once for a predetermined time. Otherwise, when the carrier signal is not received, the first and second subordinate IDs are also not detected. Therefore, the vibration controller 340 is to control the vibration generator 350 in the first vibration mode for preventing the loss to generate vibration. Here, the main ID generated from the main ID generating unit 221, the first and second subordinate ID generating units 224 and 225 of the transmission device mounted on the portable mobile radio telephone 100 or the battery pack 200, The first and second subordinate IDs are the same as the main ID and first and second subordinate IDs set in the main ID comparison unit 331 and the first and second subordinate ID comparison units 332 and 333 of the vibrator 300. ID.

As a result, the above-mentioned first vibration mode is a vibration mode for the loss prevention of the portable mobile radiotelephone, the second vibration mode is a vibration mode for notifying that the call is received, and the third vibration mode is a vibration for informing the low battery state. Mode.

An alarm method of a portable mobile radio telephone according to the present invention corresponding to such an operation will be described step by step with reference to FIG. 4.

4A and 4B are diagrams illustrating a flowchart of an alarm method of a portable mobile radio telephone according to the present invention.

First, the battery pack 200 is mounted on the portable mobile radio telephone 100 to determine whether power is supplied (S101). As a result of determination, when the power is supplied, the portable mobile radio telephone 100 continuously generates main ID information (sink signal) for preventing a loss at a predetermined time interval (S102), and at the same time, the incoming signal is detected and the battery voltage In operation S104, it is determined whether the checked battery voltage is less than or equal to the preset reference voltage (S104 and S105).

As a result of the comparison determination, when the incoming signal is detected, the first dependent ID information is generated (S106), and the generated first dependent ID information and the main ID information are combined with a carrier signal having an arbitrary frequency and transmitted to the vibrator 300. (S107). In addition, when the checked battery voltage is lower than the preset reference voltage value, second dependent ID information is generated (S109), and the generated second dependent ID information and the main ID information are combined with the carrier signal and transmitted to the vibrator 300. (S110). That is, when only the incoming signal is detected, only the main ID information and the first dependent ID information are combined with the carrier signal, and the incoming signal is not detected. When the checked battery voltage is less than or equal to the preset reference voltage, the main ID information and the second dependent ID information are transmitted. Only the ID information is combined with the carrier signal and transmitted. On the other hand, when the incoming signal is also detected and the checked battery voltage is less than the set reference voltage, the main ID information and the first and second dependent ID information are combined with the carrier signal and transmitted to the vibrator 300.

However, when the incoming signal is not detected and the checked battery voltage is detected above the preset reference voltage, when the power is supplied, only the main ID information that is continuously generated at a predetermined time interval is synthesized with the carrier signal to vibrate the device 300. To transmit (S109).

When the carrier signal including each transmitted ID information is received by the vibrator 300 (S111), after detecting each ID information included in the received carrier signal, that is, primary ID and first and second dependent ID information, In operation S112, it is checked whether the same ID information is received by comparing the detected ID information with each preset unique ID information.

As a result of the check, it is determined whether the main ID information is detected at least once within a predetermined time period (S113). If the main ID information is not detected, the portable mobile wireless telephone and the vibration device 300 are determined to have a predetermined distance or more. It is determined that there is a risk of losing the portable mobile radio telephone because it is separated from the vibration generating unit 350 in the first vibration mode having a certain period to generate a vibration (S114).

On the other hand, if the main ID is detected at least once within a predetermined time in step S113, it is determined whether all of the first and second dependent ID information is detected (S115).

As a result of the determination, when both the first and second subordinate IDs are not detected, it is determined whether the first dependent ID information is detected (S116). When the first subordinate ID is detected, that is, the main ID information and the first subordinate ID information. If is detected to drive the vibration generator 350 in the second vibration mode to inform the user that the incoming call to generate a vibration (S117).

In addition, when both the first and second dependent IDs are not detected in step S115, it is determined whether only the second dependent ID is detected (S118). When the second dependent ID information is detected, that is, the first dependent ID information is detected. If only the main ID information and the second dependent ID information are detected, the vibration generating unit (3) may be used as a third vibration mode for informing the user that the state of the battery currently installed in the portable mobile radio telephone 100 is a low battery state. 350 to drive the vibration.

On the other hand, when both the first and second subordinate IDs are not detected, the telephone is not in the incoming state, the battery state is a high battery state, and the portable mobile radio telephone 100 is located within a certain distance from the vibrator 300. It is determined that there is no risk of loss to maintain a vibration-free mode that does not generate any vibration (S 120).

When the main ID and the first and second subordinate IDs are detected at the same time in step S115, the phone is also called and the battery state is determined to be a low battery state, and vibration is first generated in the above-described second vibration mode according to a preset priority. When the vibration is generated through the unit 350 and the second vibration mode operation is completed, the vibration is generated by driving the vibration generator 350 in the third vibration mode (S121). The three vibration modes are vibration modes with different periods. That is, according to whether the primary ID and the first and second dependent ID information are detected, vibrations having different periods are generated so that the user can easily distinguish the anti-lost vibration, the incoming call vibration, and the low battery state vibration.

As a result, the alarm device and method of the portable mobile radio telephone according to the present invention generate a main ID for preventing the loss of the portable mobile radio telephone 100 at the same time while being continuously supplied at a predetermined time interval and incoming calls. When the incoming signal is detected by detecting the signal and the low battery state, or when the low battery state is detected, each of the first and second subordinate IDs corresponding thereto is generated and transmitted to the vibrator 300 together with the carrier signal.

When the carrier signal is transmitted in this way, each ID information signal received and received is detected. When the main ID is not detected at least once within a predetermined time, a first vibration is generated to prevent loss of the phone. 1 When the dependent ID information is detected, it is determined that the call is received and generates a second vibration for notifying the user that the call has been received.If the primary ID and the second dependent ID information are detected, the current battery state is determined to be a low battery state. The third vibration is generated to notify the user.

In addition, when both the primary ID and the first and second dependent ID information are detected at the same time, it is determined that the call is received and the battery state is a low battery state. First, the above-described second vibration is generated and then the third vibration is generated. At the same time, the phone is called and the user is informed that the battery is low. However, when only the main ID is detected, the mobile phone 100 is located within a certain distance from the vibrator so that there is no loss of the phone, no incoming or outgoing calls are made, and vibration is generated because the current state of the battery is determined as a high battery state. It will not be done.

The alarm device and method of the portable mobile radio telephone according to the present invention as described above are provided with a separate vibration device, to prevent the loss of the module to the battery pack or the portable mobile radio within the module, and to detect the incoming and low battery status And a transmission device for synthesizing the ID signal and the carrier signal according to the detection result and transmitting them to the vibration device. The vibration device is adapted to the carrier signal transmitted from the transmission device mounted as a module in a battery pack or a portable mobile radio telephone. According to the detection result of each ID information signal included, loss prevention vibration, incoming signal vibration and low battery state vibration having different periods can be generated, thereby preventing the loss of the portable mobile radio telephone in advance. Makes it easy to see if a call has been received. Without having to check while looking at a portable mobile radio, it has a great effect that can be easily confirmed by the vibration of the vibration device.
