Abstract

PURPOSE: A method for displaying time information in a cellular phone is provided to display time information by using an emergency battery and a separate clock counter when a level of a main battery voltage is less than a certain value, thereby always supplying the time information regardless of main battery power. CONSTITUTION: If a level of a main battery voltage is more than a certain level, a main battery power is continuously used to perform various functions(S1,S2). If the level of the main battery voltage is less than the certain value, a system converts the current main battery power into an emergency battery power, and drives an LCD by using the emergency battery power(S3,S4). The system drives an IC for a clock with the emergency battery power, sets a current time in the IC to synchronize with time information transmitted from a base station, and continuously displays a current time on the LCD by using the outputted time information(S5,S6).

Description

휴대폰의 시간정보 표시방법{METHOD FOR DISPLAYING TIME INFORMATION IN A MOBILE PHONE}How to display time information on your phone {METHOD FOR DISPLAYING TIME INFORMATION IN A MOBILE PHONE}

본 발명은 휴대폰에서 시간정보를 표시하는 기술에 관한 것으로, 특히 메인배터리 전압의 레벨이 일정치 이하로 떨어질 때 별도의 배터리와 카운터를 이용하여 계속해서 시간정보를 표시할 수 있도록 한 휴대폰의 시간정보 표시방법에 관한 것이다.The present invention relates to a technology for displaying time information in a mobile phone, and in particular, the time information of a mobile phone that can continuously display time information using a separate battery and counter when the level of the main battery voltage falls below a certain value. It relates to a display method.

근래 들어, 휴대폰의 보급률이 급속히 증가되어 현대인의 생활 필수품으로 자리매김되고 있는 실정에 있다. 이와 같은 휴대폰은 고유의 음성통화 서비스는 물론, 각종 데이터 전송 서비스와 다양한 부가서비스를 제공하므로 기능상 멀티미디어 통신기기라 할 수 있다.In recent years, the penetration rate of mobile phones has been increasing rapidly and is becoming a necessity of modern people. Such a mobile phone can be referred to as a multimedia communication device in terms of its function as it provides not only a unique voice call service but also various data transmission services and various additional services.

일반적으로, CDMA 방식의 휴대폰에서는 실시간으로 기지국으로부터 시간정보를 전송받아 엘씨디와 같은 표시장치에 표시하게 되며, GSM 방식의 휴대폰에서는자체적으로 시간을 카운트하여 표시하도록 되어 있다.In general, in a CDMA mobile phone, time information is received from a base station in real time and displayed on a display device such as an LCD. In a GSM mobile phone, time is counted and displayed on its own.

그러나, 이와 같은 종래의 휴대폰에 있어서는 배터리 전압의 레벨이 일정치 이하로 떨어지면 더 이상 시간정보가 표시되지 않아 현재 시각을 알 수 없는 불편함이 있었다.However, in such a conventional mobile phone, when the level of the battery voltage drops below a certain value, time information is no longer displayed, which makes it difficult to know the current time.

따라서, 본 발명의 목적은 배터리 전압의 레벨이 일정치 이하로 떨어지면 수은전지와 같은 비상용 배터리와 클럭 카운터를 이용하여 계속해서 시간정보를 표시하는 휴대폰의 시간정보 표시방법을 제공함에 있다.Accordingly, an object of the present invention is to provide a time information display method of a mobile phone which continuously displays time information by using an emergency battery such as a mercury cell and a clock counter when the level of the battery voltage drops below a certain value.

도 1은 본 발명에 의한 휴대폰의 시간정보 표시방법의 처리과정을 나타낸 신호 흐름도.1 is a signal flow diagram illustrating a process of a time information display method of a mobile phone according to the present invention.

본 발명에 의한 휴대폰의 시간정보 표시방법은, 메인배터리 전압의 레벨이 일정치 이상인 경우 그 메인 배터리의 전원을 계속 사용하여 현재시간 표시 기능 및 각종 기능을 수행하는 제1과정과; 상기 메인배터리 전압의 레벨이 일정치 이하인 경우 사용전원을 메인배터리에서 비상용 배터리로 절환하여 엘씨디를 구동하는 제2과정과; 현재 시간을 클럭용 집적소자에 셋팅한 후 이로부터 출력되는 시간정보를 이용하여 계속해서 상기 엘씨디에 현재 시간을 표시하는 제3과정으로 이루어지는 것으로, 이와 같이 이루어지는 본 발명의 시간표시 방법의 처리과정을 첨부한 도 1을 참조하여 상세히 설명하면 다음과 같다.The time information display method of the mobile phone according to the present invention includes a first step of performing a current time display function and various functions by continuously using power of the main battery when the level of the main battery voltage is higher than a predetermined value; A second step of switching the power supply from the main battery to the emergency battery when the main battery voltage level is lower than a predetermined value to drive the LCD; And a third process of continuously displaying the current time on the LCD using the time information outputted therefrom after setting the current time in the clock integrated device. A detailed description with reference to the accompanying Figure 1 as follows.

메인배터리 전압의 레벨을 소정 주기로 체크하여 일정치(Vref) 즉, 단말기를 정상적으로 구동하는데 필요한 레벨 이상인 것으로 판명되면 그 메인 배터리의 전원을 계속 사용하여 각종 기능을 수행한다.(S1,S2)When the level of the main battery voltage is checked at predetermined intervals and found to be higher than a predetermined value (Vref), that is, the level required for driving the terminal normally, the main battery power is continuously used to perform various functions.

이때에는 기지국으로부터 전송되어 오는 실시간 시간정보를 이용하여 엘씨디에 현재 시간 정보를 표시하게 된다.At this time, the current time information is displayed on the LCD using real time time information transmitted from the base station.

이후, 일정 시간이 경과되어 상기 메인배터리 전압의 레벨 체크 결과 일정치(Vref) 이하로 판명되면, 이때부터 수은전지와 같은 비상용 배터리를 사용하여 다음과 같이 시간정보를 표시하게 된다.Subsequently, when a predetermined time elapses and the main battery voltage is checked to be below a predetermined value (Vref), time information is displayed as follows using an emergency battery such as a mercury battery.

즉, 현재 사용전원을 메인배터리에서 비상용 배터리로 절환하고, 그 비상용 배터리 전원을 이용하여 엘씨디를 구동한다.(S3,S4)That is, the current power supply is switched from the main battery to the emergency battery, and the LCD is driven using the emergency battery power (S3, S4).

또한, 상기 비상용 배터리 전원으로 클럭용 집적소자를 구동시키고, 현재 시간을 그 클럭용 집적소자에 셋팅하여 기지국에서 전송되는 시간정보와 동기시킨 후 이로부터 출력되는 시간정보를 이용하여 계속해서 상기 엘씨디에 현재 시간을 표시하게 된다.(S5,S6)In addition, the clock integrated device is driven by the emergency battery power, and the current time is set in the clock integrated device to synchronize with the time information transmitted from the base station, and then the time information outputted therefrom is continuously used. The current time is displayed (S5, S6).

상기 클럭용 집적소자는 상기 수은전지와 같은 비상용 배터리의 전원을 사용하는 것을 감안하여, 저소비전력형으로 설계하였다.The clock integrated device is designed in a low power consumption type in consideration of using a power source of an emergency battery such as a mercury battery.

상기 설명에서는 휴대 단말기가 CDMA 방식인 것을 예로한 것이며, GSM 방식의 단말기인 경우에도 동일한 원리가 적용된다.In the above description, the portable terminal is a CDMA system as an example, and the same principle applies to a GSM terminal.

단, 메인배터리 전압의 레벨이 일정치일정치(Vref) 이상인 경우에는 자체 발진신호 및 카운터를 이용하여 현재 시간 정보를 생성해서 엘씨디에 표시하다가, 메인배터리 전압의 레벨이 일정치일정치(Vref) 이하로 떨어지면 상기와 같이 현재 시간을 클럭용 집적소자에 셋팅하여 계속해서 이로부터 현재 시간 정보가 제공되고, 이 시간정보를 이용하여 상기 엘씨디에 현재 시간을 표시하는 것이 다른 점이다.However, if the level of the main battery voltage is higher than the predetermined constant value (Vref), the current time information is generated and displayed on the LCD by using the self-oscillation signal and the counter, and the level of the main battery voltage is constant. If it falls below, the current time is set in the clock integrated device as described above, and the current time information is continuously provided therefrom, and the current time is displayed on the LCD using this time information.

이상에서 상세히 설명한 바와 같이 본 발명은 메인배터리 전압의 레벨이 일정치 이하로 떨어지면 수은전지와 같은 비상용 배터리와 별도의 클럭 카운터를 이용하여 시간정보를 표시함으로써, 메인배터리 전원에 관계없이 항상 시간정보를 제공할 수 있는 효과가 있다.As described in detail above, the present invention displays time information using an emergency battery such as a mercury cell and a separate clock counter when the level of the main battery voltage falls below a predetermined value, thereby always displaying time information regardless of the main battery power supply. There is an effect that can be provided.
