코드없는 무선전화기에 있어서, 베이스의 송신단은, 안테나로 부터 전력증폭부(1) RF여파부(2)및 주자수 3체기(3)를 경유하여 종속접속되는, FM변조단(4)에 접속되어 입력되는 데이타 신호에 따라 일정한 주파수를 생성하는 모뎀(20)과, B+단자로부터DIP스위치(6)및 스위치SW1을 경유하는 접속되는 동시에 상기 주파수 3체배기(3)의 동작을 제어할 수 있도록 접속되어 상기 DIP스위치(6)의 상태에 따라 그에 해당하는 데이타를 저장하고 이를 상기 모뎀(20)에 저장하는 동시에 상기 스위치SW1의 on,off에 따라 상기 주파수 3체배기를 구동할 수 있는 신호를 출력하는 마이크로 컴퓨터제어부(5)로 구성되고, 핸드셋의 수신단은, 안테나로 부터 RF여파부(2'), RF증폭부(7), 혼합부(8)및 중간여파기(10)를 경유하며 종속접속되는 복조부(11)에 접속되어, 입력되는 신호외의 주파수를 차단하는 데이타 여파기(13)와, 상기 데이타 여파기로부터 접속되어 입력되는 데이타신호를 디지탈신호로 변환하는 모뎀(20')과, 상기 모뎀(20')으로 부터 그리고 B+단자로 부터 DIP스위치부(6')를 경유하여 접속되어 상기 DIP스위치부(6')의 데이타와 상기 모뎀(20')로 부터 출력되는 데이타를 비교하여, 그에 접속된 LED표시부(16)및 부저(15)를 동작시키는 마이크로 프로세서 제어부(5')로 구성하여, 그로 인하여 베이스측으로 부터 핸드셋이 송수신 가능거리를 이탈할 시 이를 인지할 수 있는 것을 특징으로 하는 코드없는 무선핸드셋의 통달거리 초과경보회로.In a cordless telephone, the base transmitter is connected to the FM modulator 4, which is cascaded from the antenna via the power amplifier 1, the RF filter 2 and the number of runners 3. And a modem 20 for generating a constant frequency in accordance with the input data signal, and connected via the DIP switch 6 and the switch SW 1 from the B + terminal to simultaneously control the operation of the triplex multiplier 3. Connected to store the corresponding data according to the state of the DIP switch 6 and to store the data to the modem 20 and at the same time to drive the frequency triplex according to the on and off of the switch SW 1 It consists of a microcomputer control unit 5 for outputting, and the receiving end of the handset is dependent from the antenna via the RF filter unit 2 ', the RF amplifier unit 7, the mixing unit 8 and the intermediate filter 10. Frequency other than the input signal which is connected to the demodulation section 11 to be connected A data filter 13 for blocking the number, a modem 20 'for converting a data signal connected and input from the data filter into a digital signal, and a DIP switch section from the modem 20' and from the B + terminal. The data of the DIP switch 6 'and the data output from the modem 20' are connected via 6 ', and the LED display 16 and the buzzer 15 connected thereto are operated. And a microprocessor controller (5 '), so that the handset can recognize when the handset deviates from the transmit / receive distance from the base side. 코드없는 무선핸드셋의 통달거리 초과경보회로의 제어방법에 있어서, 베이스의 송신단은, 시작신호로부터 핸드셋이 베이스로부터 이탈되었는지의 여부를 판단하고 DIP스위치부(6)의 데이타를 저장하는 단계와, 상기 단계로부터 주파수 3체배기를 동작시키고 버퍼에 저장된 데이타를 모뎀에 하나씩 출력하는 단계와, 상기 단계로 부터 출력이 예를 들어 5번 되었는지를 판단하고 일정시간 상기 주파수 3체배기를 off시키고 다시 시작단계로 복귀되는 단계와, 핸드셋의 수신단은, 시작신호로부터 버퍼에 DIP스위치부(6')의 데이타를 저장하고 베이스측으로부터 데이타가 입력되었는지의 여부를 판단하는단계와, 데이타 입력여부판별에 따라일정시간 경과 후 다시 데이타 입력여부를 판별하여 부저 및 LED를 구동시키는 단계와, 데이타 입력 여부판별에 따라 입력된 데이타를 버퍼에 저장하고 데이타가 예를 들어 5번 들어왔는지의 여부를 판단하는 단계와, 상기 단계로부터 입력된 데이타의 상기 DIP스위치부(6')의 데이타를 비교하여 동일한지의 여부를 판단하는 단계와, 상기 단계의 판별에 따라 시작단계로 복귀하거나, 일정시간 경과 후에 다시 데이타가 입력되었는지의 판별에 따라 부저 및 LED를 구동하는 단계로 이루어진 것을 특징으로 하는 코드없이 무선핸드셋의 통달거리 초과경보회로의 제어방법.In the control method of the communication distance over-alarm circuit of a cordless wireless handset, the base transmitting end judges whether the handset is separated from the base from the start signal, and stores the data of the DIP switch unit 6; Operating the frequency triplex from the step and outputting the data stored in the buffer to the modem one by one; judging whether the output has been five times from the step, and turning off the frequency triplex for a certain time and returning to the start step again. And the step of storing the data of the DIP switch unit 6 'in the buffer from the start signal and determining whether or not data has been input from the base side, and a predetermined time elapses according to whether data is input or not. After determining whether data is input again, driving the buzzer and LED, and determining whether data is input Storing the inputted data in a buffer and determining whether or not the data came in, for example, five times, and comparing the data of the DIP switch unit 6 'of the data input from the step to determine whether or not it is the same. And a step of driving the buzzer and the LED according to the determination of whether the data is input again after a predetermined time or after the predetermined time has elapsed. Control method of the circuit. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
