본 고안은 디지탈 비밀 테이타 시스템을 이용하는 이동을 무선장비에 관한 것으로, 특히 충전단자를 이용하여 데이타 전송 및 배터리 충전을 동시에 하며 과충전 방지에 적닿하도록 한 배터리 충전회로에 관한 것이다.The present invention relates to a wireless device for the movement using a digital secret data system, and more particularly to a battery charging circuit that allows data transmission and battery charging at the same time and in close contact with overcharge protection using a charging terminal.
종래의 배터리 충전회로는 제1도에 도시된 바와같이, 충전전원공급장치(VA)가 충전단자(T1),(T2)에 접속된 무선전화기 본체(1)와, 충전단자(T3)가 전류조정용 가변저항(VR)을 통한 후 스위치(S1)를 다시 통해 충전배터리(VB)의 플러스단자에 접속되고, 그 충전배터리(VB)의 마이너스단자가 충전단자(T4)에 접속된 무선전화가 핸드세트(2)로 구성되어 있다.In the conventional battery charging circuit, as shown in FIG. 1, the main body 1 of the wireless telephone in which the charging power supply VA is connected to the charging terminals T1 and T2, and the charging terminal T3 are currents. The radiotelephone is connected to the positive terminal of the charging battery V B through the switch S1 and then through the adjustable variable resistance VR, and the negative terminal of the charging battery V B is connected to the charging terminal T4.

In this case, the switch S1 is turned on, and the charging current supplied from the charging power supply VA to the charging terminal T1 is transferred to the charging terminal T3, the variable resistor VR and the switch of the handset 2. The charging battery V B is charged through S1), and when the handset 2 is lifted from the main body 1, the switch S1 is turned off to stop charging. A separate overcharge protection circuit is provided to prevent overcharging. There was a defect that had to be controlled for overcharging.
본 고안은 이와같은 종래의 결함을 감안하여, 이동용 무선장비의 핸드세트에 내장된 충전용 배터리를 충전하면서 장비운용상 필요한 비밀테이타를 전송시키도록 하여 별도의 과충전 보호회로가 필요하지 않는 배터리 충전회로를 안출한 것으로, 이를 첨부한 제2도의 본 고안 충전잔자를 이용한 데이타전송 및 과충전이 방지되는 배터리 충전회로를 참조해 상세한 설명하면 다음과 같다.The present invention, in consideration of such a conventional defect, while charging the rechargeable battery built in the handset of the mobile radio equipment to transmit the secret data necessary for the operation of the battery charging circuit that does not require a separate overcharge protection circuit The present invention will be described in detail with reference to the battery charging circuit which prevents data transmission and overcharge using the present invention charging residue attached thereto.
제2도는 본 고안의 충전단자를 이용한 데이타 전송 및 과충전이 방지되는 배터리 충전회로도서, 이에 도시한 바와같이 중앙처리장치(CPU1)의 송신단자(TX1)를 저항(R1)을 통해 저항(R2) 및 트랜지스터(TR1)의 베이스에 접속하고, 중앙처리장치(CPU1)의 송신단자(TX2)를 다이오드(D1)를 통해 트랜지스터(TR2)의 콜렉터에 접속하며, 전원단자(Vcc)를 가변저항(VR1)을 통해 트랜지스터(TR3)의 에미터에 접속함과 아울러 그 전원단자(Vcc)를 저항(R3)을 통해 그 트랜지스터(TR3)의 베이스에 접속하여, 그 접속점을 저항(R4)을 다시 통해 상기 트랜지스터(TR1)의 콜렉터에 접속하며, 상기 트랜지스터(TR3)의 콜렉터를 충전단자(T1)에 접속함과 아울러 다이오드(D2)를 역방향으로 통해 충전단자(T2)에 접속하고, 그 접속점을 저항(R5)을 통해 저항(R6) 및 상기 트랜지스터(TR2)의 베이스에 접속하여 무선전화기 본체(11)를 구성하고, 상기 충전단자(T1)에 접촉되는 충전단자(T3)를 가변저항(VR2)을 통해 중앙처리장치(CPU2)의 수신단자(RX2)에 접속함과 아울러 다이오드(D3), 스위치(S11) 및 충전배터리(VB11)를 통해 그 중앙처리장치(CPU2)의 수신단자(RX1) 및 상기 충전단자(T2)에 접촉되는 충전단자(T4)에 접속하여 무선전화기 핸드세트(12)를 구성한 것으로, 이와같이 구성된 본 고안의 작용효과를 상세히 설명하면 다음과 같다.2 is a battery charging circuit diagram to prevent data transmission and overcharging using the charging terminal of the present invention. As shown therein, the transmission terminal TX1 of the central processing unit CPU1 is connected to the resistor R2 through the resistor R1. And the base of the transistor TR1, the transmission terminal TX2 of the central processing unit CPU1 is connected to the collector of the transistor TR2 through the diode D1, and the power supply terminal Vcc is connected to the variable resistor VR1. Is connected to the emitter of the transistor TR3, and the power supply terminal Vcc is connected to the base of the transistor TR3 through the resistor R3, and the connection point is connected again through the resistor R4. The transistor TR1 is connected to the collector, the collector of the transistor TR3 is connected to the charging terminal T1, the diode D2 is connected to the charging terminal T2 through the reverse direction, and the connection point is connected to the resistor ( Through R5 is in contact with the resistor R6 and the base of the transistor TR2 The main body 11 of the wireless telephone, and the charging terminal T3 in contact with the charging terminal T1 is connected to the receiving terminal RX2 of the CPU 2 through a variable resistor VR2. by connecting a diode (D3), the switch (S11) and the reception terminal (RX1) and the charging terminal (T4) in contact with the charging terminal (T2) for charging the battery (V B 11) the central processing unit (CPU2) via When the radiotelephone handset 12 is configured, the operational effects of the present invention configured as described above will be described in detail.
전원단자(Vcc)에 전원이 인가되고, 무선전화기 본체(11)에 무선전화기 핸드세트(12)를 올려놓아 그 본체(11)의 충전단자(T1),(T2)에 에 핸드세트(12)의 충전단자(T3),(T4)가 접촉되면, 이때 스위치(S11)가 온되고, 또한 이때 중앙처리장치(CPU1)의 송신단자(TX1)에서 출력되는 고전위에 의해 트랜지스터(TR1)가 턴온되므로 그의 콜렉터에 저전위가 출력되어 트랜지스터(TR3)가 도통된다. 따라서, 이때 전원단자(Vcc)의 전원이 가변저항(VR1) 및 트랜지스터(TR3)를 통한 후 충전단자(T1),(T3), 가변저항(VR2), 다이오드(D3) 및 스위치(S11)를 다시 통해서 충전배터리(VB11)에 충전된다.Power is applied to the power supply terminal Vcc, and the wireless telephone handset 12 is placed on the cordless telephone main body 11 and the handset 12 is connected to the charging terminals T1 and T2 of the main body 11. When the charging terminals (T3), (T4) of the contact, the switch (S11) is turned on at this time, the transistor TR1 is turned on by the high potential output from the transmission terminal (TX1) of the central processing unit (CPU1). The low potential is output to the collector thereof, and the transistor TR3 is turned on. Therefore, at this time, the power of the power supply terminal Vcc passes through the variable resistor VR1 and the transistor TR3, and then charges the terminals T1, T3, the variable resistor VR2, the diode D3, and the switch S11. The charging battery VB 11 is charged again.
또한, 상기 충전배터리(VB11)의 충전시에 그의 충전전류가 충전단자(T4),(T2)를 통한 후 저항(R5),(R6)에 의해 분압되어 트랜지스터(TR2)의 베이스에 바이어스전압으로 공급되고, 이때 그 트랜지스터(TR2)가 도통되면 중앙처리장치(CPU1)의 송신단자(TX2)에서 다이오드(D1)를 통한 후 상기 트랜지스터(TR2)의 콜렉터에서 에미터로 흐르는 전류로가 형성되므로 그 중앙처리장치(CPU1)에서 그 송신단자(TX2)를 통해 충전상태를 감지하게 된다.In addition, when the charging battery V B 11 is charged, its charging current is divided by the resistors R5 and R6 through the charging terminals T4 and T2 and biased to the base of the transistor TR2. When the transistor TR2 is turned on, a current path flows through the diode D1 at the transmit terminal TX2 of the CPU 1 and then flows from the collector of the transistor TR2 to the emitter. Therefore, the central processing unit CPU1 detects the charging state through the transmission terminal TX2.
따라서, 이때 그 중앙처리장치(CPU1)에서 그의 송신단자(TX1)를 통해 시스템 운용에 필요한 데이타를 트랜지스터(TR1)의 베이스에 전송하여 그 트랜지스터(TR1)의 동작을 단속하면, 그 트랜지스터(TR1)의 동작에 의해 상기 트랜지스터(TR3)의 온,오프가 단속되어 무선전화기 핸드세트(12)내의 중앙처리장치(CPU2)의 시스템 운용에 필요한 데이타를 전송하게 되며, 아울러 배터리(VB11)의 충전도 트랜지스터(TR3)의 온,오프에 의해 단속하게 된다. 이때 배터리(VB11)의 충전특성은 제3도 충전특성 파형도에 도시된 바와같이 충전전류 공급시간(t1)과 충전전류 휴지시간(ti)을 조정하여 과충전이 방지되는데, 충전전류(Ii)의 크기를 조절하여 충전배터리(VB11)의 충전시간조절이 가능하며, 그 충전전류(Ii)의 크기는 제2도의 가변저항(VR1),(VR2)을 조정하여 조절할 수 있으며, 무선전화기 본체(11)에서 핸드세트(12)를 들면 충전이 중지된다.Therefore, at this time, the CPU TR1 transfers data necessary for operating the system to the base of the transistor TR1 through its transmission terminal TX1 to interrupt the operation of the transistor TR1. By the operation of the transistor TR3 on and off is interrupted to transmit data necessary for the system operation of the central processing unit (CPU2) in the wireless telephone handset 12, and also to charge the battery (V B 11) Also, the transistor TR3 is interrupted by turning on and off. At this time, the charging characteristic of the battery V B 11 is prevented from overcharging by adjusting the charging current supply time t1 and the charging current rest time ti as shown in FIG. 3. It is possible to adjust the charging time of the charging battery (V B 11) by adjusting the size of the battery, and the size of the charging current (Ii) can be adjusted by adjusting the variable resistors VR1 and VR2 of FIG. Charging is stopped by lifting the handset 12 from the telephone body 11.
따라서, 무선전화기 본체(11)내의 중앙처리장치(CPU1)의 시스템 운용에 필요한 데이타를 송신하면, 그 데이타를 송신에 의해 토랜지스터(TR3)가 단속되어 송신한 데이타를 핸드세트(12)내의 중앙처리장치(CPU2)가 수신하게 됨과 아울러 충전배터리(VB11)에 충전되는데, 충전전류 공급시간 (t1)과 충전전류 휴지시간(ti)을 조절하여 과충전이 방지된다.Therefore, when data required for the system operation of the central processing unit CPU1 in the radio telephone main body 11 is transmitted, the toristor TR3 is interrupted by the transmission of the data and the transmitted data in the handset 12 is transmitted. The central processing unit (CPU2) is received and also charged in the charging battery (V B 11), by controlling the charging current supply time (t1) and the charging current idle time (ti) to prevent overcharge.
이상에서 상세히 설명한 바와같이 본 고안은 무선전화기 본체에서 시스템 운용에 필요한 데이타를 전송함과 아울러 충전배터리를 충전시키며, 충전전류 공급시간과 충전전류 휴지시간이 조정되어 과충전이 방지되는 효과가 있게 된다.As described in detail above, the present invention transmits data necessary for operating the system from the wireless telephone body, charges the rechargeable battery, and adjusts the charging current supply time and the charging current rest time, thereby preventing overcharge.
