본 발명은 무선전화기의 자동통화방법에 관한 것으로서 특히, 무선전화기의 휴대장치를 고정장치에서 들어올리면 자동적으로 통화모드로 전환되고 고정장치에 얹어 놓으면 자동적으로 대기 모드로 전환되어 자동통확 가능토록 한 것이다.The present invention relates to an automatic call method for a wireless telephone, and in particular, when the portable device of the wireless telephone is lifted from the fixed device, the mobile phone is automatically switched to the call mode, and when placed on the fixed device, the mobile phone is automatically switched to the standby mode to enable automatic communication. .

종래의 무선전화기는 제1도에서와 같이 안테나(12)를 통한 무선신호를 수신하는 수신증폭부(1a)와 중간 주파증폭부(1b) 및 오디오증폭부(1c)로 구성된 수신부(1)와, 또한 안테나(12)를 통해 무선신호를 송출하는 송신출력부(2a), 변조부(2b) 및 마이크(13) 신호를 증폭하는 마이크증폭부(2c)로 구성된 송신부(2)와, 상기 송신부(2)의 전력을 제어하는 전력제어부(8)와, 모든 제어로직을 수행하는 중앙처리장치(이하 CPU라 약칭함)(3)와, 키신호입력을 위한 키입력부(G)와, 모드선택을 위한 통화/대기스위치입력부(7)와, 자동대기/통화상태를 판단하기 위한 충전검출부(5) 및 충전부(4)로 구성되어 고정장치(10)에 설치된 고정장치충전부(9)에 장착되도록 구성되어져 있다.Conventional radiotelephones include a receiver 1 comprising a reception amplifier 1a, an intermediate frequency amplifier 1b, and an audio amplifier 1c for receiving a radio signal through the antenna 12 as shown in FIG. And a transmitter 2 comprising a transmitter output section 2a for transmitting a radio signal through the antenna 12, a modulator 2b, and a microphone amplifier 2c for amplifying the microphone 13 signal, and the transmitter A power control section 8 for controlling the power of (2), a central processing unit (hereinafter referred to as CPU) (3) for performing all control logic, a key input section (G) for key signal input, and mode selection Call / standby switch input unit 7 for, and the charge detection unit (5) and the charging unit (4) for determining the automatic standby / call state to be mounted on the fixed device charging unit (9) installed in the fixed device (10) It is composed.

이와같이 구성된 종래의 무선전화기의 자동통화 및 자동대기 기능은 제2도에 나타낸 바와같이 통화/대기스위치 입력부(7)가 통화위치에 있는 상태에서는 총전부(4)와, 충전검출부(5)의 전력제어부(8)가 동작하게 되는데 이때 고정장치 충전부(9)에 휴대장치의 충전부(4)와 충전검출부(5)가 놓여지면 충전검출부(5)에 밧데리 전원(BT)인 소정치(3, 6)볼트의 전원이 인가되어 CPU(3)는 통화/대기스위치 입력부(7)의 위치를 해독하여 만일 통화위치에 있으면 CPU(3)에서는 그의 출력포트(O2)를 통해 송신부(2)에 대기 제어코드를 송출하므로 대기상태가 된다.The automatic call and auto standby function of the conventional radiotelephone configured as described above has the power of the total power section 4 and the charge detection section 5 when the call / standby switch input section 7 is in the call position as shown in FIG. The control unit 8 is operated. At this time, when the charging unit 4 and the charging detection unit 5 of the portable device are placed in the charging unit 9, the predetermined value (3, 6), which is a battery power source BT, is applied to the charging detection unit 5. When the power of the bolt is applied, the CPU 3 decodes the position of the call / standby switch input unit 7 and if it is in the call position, the CPU 3 waits for the transmission unit 2 through its output port O 2 . The control code is sent to make it stand by.

한편, 휴대장치를 고정장치에서 들게되면 충전부(4)와 충전검출부(5)가 고정장치 충전부(7)에서 분리되어 충전검출부(5)에는 소정치 이하(0볼트)의 전원이 인가되어 이때 CPU(3)에서는 그의 출력포트(O2)를 통해 송신부(2)에 통화제어코드를 송출하므로 통화상태가 된다. 만일 통화/대기스위치 이력부(7)가 대기위치에 있으면 그 동작은 수행되지 않는다.On the other hand, when the portable device is lifted from the fixing device, the charging unit 4 and the charging detection unit 5 are separated from the charging unit charging unit 7, and the charging detection unit 5 is supplied with a power of less than a predetermined value (0 volts). In (3), the call control code is sent to the transmitting unit 2 through its output port O 2 , and the call state is established. If the call / wait switch history section 7 is in the standby position, the operation is not performed.

그러나 이러한 종래의 무선전화기는 정전시 고정장치(10)의 충전부에 전원 공급이 없을때에도 고정장치(10)에 휴대장치가 얹어져 있는 상태에서는 휴대장치를 들어올리는 것과 마찬가지로 통화모드로 되기 때문에 불필요한 전파를 송출하는 경우가 발생하고 또한 통화/대기스위치 입력부의 위치에 따라 자동 통화기능이 선택되어지는 문제점이 발생되었다.However, such a conventional radiotelephone has an unnecessary propagation because it is in a call mode similar to lifting a portable device in a state in which the portable device is placed on the fixed device 10 even when there is no power supply to the charging unit of the fixed device 10 during a power failure. There was a problem that the call and the automatic call function is selected depending on the position of the call / standby switch input.

본 발명은 이러한 종래의 문제점을 해소시키는 방법을 제안하는 것으로서, 무선전화기의 통화/대기모드스위치 선택 상태에 관계없이 고정장치에 재치되는 휴대장치의 충전상태를 CPU에서 감지하여 그의 출력상태에 따라 송신부 및 수신부의 동작을 제어하여 정전시에는 통화모드 전환을 방지하는 동시에 고정장치로 부터 휴대장치를 들게 되면 자동적으로 통화가 이루어지도록 한 것으로, 이를 첨부된 도면에 의해 상세히 설명하면 다음과 같다.The present invention proposes a method for solving such a conventional problem, and the CPU detects the charging state of the portable device mounted on the fixed device regardless of the call / standby mode switch selection state of the wireless telephone and transmits the signal according to its output state. And by controlling the operation of the receiver to prevent the switching of the call mode in the event of a power failure, the call is made automatically when the portable device is lifted from the fixed device, which will be described in detail by the accompanying drawings as follows.

제3도는 본 발명에 따른 무선전화기의 블록구성도로서, 안테나(12)를 통화 무선신호를 수신하는 수신증폭부(1a) 중간주파증폭부(1b) 및 오디오증폭부(1c)로 구성된 수신부(1)와, 안테나(12)를 통해 무선신호를 송출하는 송신출력부(2a), 변조부(2b) 및 마이크(13) 신호를 증폭하는 마이크증폭부(2c)로 구성된 송신부(2)와, 상기 송신부(2)의 전력공급을 제어하는 전력제어부(8)와, 모든 제어로직을 수행하는 CPU(3)와, 키 신호입력을 위한 키입력부(6)와, 자동대기/통화상태를 판단하기 위한 충전검출부(5) 및 충전부(4)로 구성되어 고정장치(10)에 설치된 고정장치 충전부(9)에 장착되도록 구성되어져 있다.3 is a block diagram of a radiotelephone according to the present invention, wherein the antenna 12 includes a receiving unit 1a, an intermediate frequency amplifier 1b, and an audio amplifier 1c for receiving a radio signal for a call ( 1), a transmission unit 2 composed of a transmission output unit 2a for transmitting a radio signal through the antenna 12, a modulation unit 2b, and a microphone amplifier 2c for amplifying the microphone 13 signal, Determining the power control unit 8 for controlling the power supply of the transmitter 2, the CPU 3 performing all control logic, the key input unit 6 for key signal input, and the automatic standby / call state It is configured to be mounted on the fixing device charging unit 9 installed in the fixing device 10 is composed of a charging detection unit 5 and the charging unit 4 for.

이와같이 구성되는 본 발명에 따른 무선전화기와 관련된 자동통화방법은 휴대장치의 충전부가 고정장치의 충전부에 놓여져 있는가를 휴대장치내의 중앙처리장치에서 검출하여 들려진 상태에서 충전검출부의 전압이 소정치 이하이면 전력제어부를 구동시켜 송신부에 전원을 공급하는 동시에 통화제어코드를 송출한후 통화인지 코드를 입력받아 통화모드를 수행하는 통화모드 처리과정과, 휴대장치가 고정장치에 놓여지고 통화중인 상태에서 충전검출부의 전압이 소정치이면 상기 중앙처리장치에서는 송신부에 대기제어코드를 송출하는 동시에 전력제어부의 구동을 차단시켜 정전시 자동통화기능을 방지하도록 대기모드를 수행하는 대기모드 처리과정으로 이루어진다.The automatic call method related to the radiotelephone according to the present invention configured as described above is performed by detecting whether the charging unit of the portable device is placed in the charging unit of the fixed device. The call mode processing process of performing a call mode by receiving a call recognition code after transmitting a call control code while supplying power to a transmitter by driving a control unit; If the voltage is a predetermined value, the central processing unit sends a standby control code to the transmitter and at the same time shuts off the operation of the power controller to perform a standby mode processing to perform the standby mode to prevent the automatic call function in case of power failure.

이와같이 이루어진 본 발명의 자동통화방법은 휴대장치에 장착되어있는 충전부(4) 및 충전검출부(5)와, 이에 연관되어 동작하는 자동통화기능에 대한 CPU(3)의 제어동작은 제4도에 놓여져 있는가를 검출하여 놓여져 있을때는 충전검출부(5)의 전압이 그 자체 밧데리 용량에 따라 소정치(3, 6볼트)가 인가되어 있다가 충전부(4)가 고정장치 충전부(9)에서 분리되면 충전검출부(5)의 전압이 소정치 이하(0볼트)가 인가되어 CPU(3)는 그 전압을 감지하여 전력제어부(8)를 구동시키며 그의 출력포트(O2)를 통해 통화제어코드를 송신부(2) 및 안테나(12)를 통해 고정장치(10)로 송출한다. 이에 수신부(1)를 통해 CPU(3)가 고정장치(10)로부터 통화인지코드를 받아 통화모드로 제어하게 된다.In the automatic call method according to the present invention, the charging part 4 and the charging detection part 5 mounted on the portable apparatus, and the control operation of the CPU 3 for the automatic call function operating in association therewith are placed in FIG. When it is detected and placed, the predetermined value (3, 6 volts) is applied according to the battery capacity of the charge detecting unit 5, and when the charging unit 4 is separated from the fixing unit charging unit 9, the charge detecting unit ( below the predetermined value, the voltage of 5) (0 volt) is applied to CPU (3) is sikimyeo driving power control unit 8 detects the voltage its output port (O 2), the call control code transmission unit (2) through And it is sent to the fixing device 10 through the antenna 12. Accordingly, the CPU 3 receives the call recognition code from the fixing device 10 through the receiver 1 to control the call mode.

한편, 충전부(4)가 고정장치(10)의 고정장치충전부(9)로부터 분리된 상태에서 통화모드에 있을 때에는 충전검출부(5)의 전압이 0볼트 상태이었다가 이후에 충전부(4)가 고정장치 충전부(9)에 놓여지면 충전검출부(5)의 전압은 소정치(3, 6볼트)로 상승되며 이때 CPU(3)는 그 전압을 감지하여 전력제어부(8)의 구동을 차단시키며 그의 출력포트(O2)를 통한 대기 제어코드를 송신부(2) 및 안테나(12)를 통해 송출하고 대기모드로 되돌아 가도록 제어하게 된다. 즉, 무선전화기의 고정장치에 인가되는 전원이 정전등으로 인가하여 차단되었을 경우에 휴대장치를 고정장치로 부터 들어올렸을 경우와 마찬가지로 오인식하여 통화모드로 전환되는 것을 방지할 수가 있고 반드시 휴대장치를 고정장치에서 들어올렸을 경우에만 자동통화가 이루어지도록 한 것이다.On the other hand, when the charging unit 4 is in the call mode in a state where the charging unit 4 is separated from the fixing unit charging unit 9 of the fixing unit 10, the voltage of the charging detecting unit 5 is 0 volts, and then the charging unit 4 is fixed. When placed in the device charging section 9, the voltage of the charging detection section 5 rises to a predetermined value (3, 6 volts), at which time the CPU 3 senses the voltage and cuts off the driving of the power control section 8 and outputs it. The standby control code through the port O 2 is transmitted through the transmitter 2 and the antenna 12 to control to return to the standby mode. That is, when the power applied to the fixed device of the radiotelephone is cut off due to a power failure or the like, when the portable device is lifted from the fixed device, the mobile device can be misrecognized and switched to the call mode. Automatic calls only occur when lifted from the device.

이상에서와 같이 본 발명은 무선전화기에 공급되는 전원이 정전되거나 또는 고정장치 전원이 오프되었을 때 CPU에서는 그 통화모드에 관계없이 휴대장치가 통화상태로 가는 것을 방지할 수 있게 되어 유·무선전화기의 이중효과를 얻을 수 있으며, 또한 별도의 버튼조작이나 스위치 조작에 의해서 통화 및 대기상태가 제어되는 것이 아니라 휴대장치를 고정장치의 충전기로부터 분리함으로써 통화모드를 수행할 수가 있으므로 그 사용이 매우 편리한 효과를 제공할 수 있다.As described above, the present invention can prevent the portable device from going into a call state regardless of the call mode of the CPU when the power supplied to the wireless telephone is interrupted or the power of the fixed device is turned off. The dual effect can be obtained, and the call and standby state can not be controlled by separate button operation or switch operation, but the call mode can be performed by separating the portable device from the charger of the fixed device. Can provide.
