Abstract

The Conservation device preventing the pre-register data loss even in the power interruption has the processor (2) controlling the system; the serial-to-parallel data converter (8) converting the registered parallel data to serial format to feed the converted data to the non-volatile memory means (9); the parallel-to-serial data converter (10) converting the saved data to parallel format to provide the converted data to the processor (2). The data conservation device can save the dissipation power because it can keep the pre-register data in off-line power state.

본 발명은 TV수상기, VCR 등의 전자, 전기제품에서 마이컴에 의한 기기제어 동작의 예약(예 : 예약 녹화, 취침시 전원 자동오프, 등등) 데이타를 정전시에도 보존하여 데이타 상실을 방지할 수 있도록 한 예약 데이타 보존장치에 관한 것이다.The present invention can prevent the loss of data by preserving data (reservation recording, automatic power-off at bedtime, etc.) of the device control operation by the microcomputer in electronic and electrical appliances such as TV receivers, VCRs, etc. in case of power failure. It relates to a reservation data storage device.

종래의 예약기능을 갖는 전자, 전기제품에서 예약데이타를 마이컴의 RAM에 저장하므로 상시 스탠-바이 전원이 공급되고 있어야 하며 제 1 도에 도시된 바와 같이 마이컴(1)의 전원단에 순간정전시 예약데이타 보존을 위한 콘덴서(C1) 및 역전류 저지용 다이오드(D1)를 구비하므로서 순간 정전시 전원(B+)이 차단되면 콘덴서(C1)에 충전된 전압으로 일정한 시간동안 임시전원을 공급하고 있다.In electronic and electrical appliances having a conventional reservation function, reservation data is stored in the RAM of the microcomputer, so that standby power must be supplied at all times. As shown in FIG. Since the capacitor C1 for data preservation and the reverse current blocking diode D1 are provided, when the power supply B + is cut off during a momentary power failure, the temporary power is supplied for a predetermined time with the voltage charged to the capacitor C1.

그러나 이와 같은 회로는 순간정전에 대비키 위한 것이므로 정전이 장시간 지속되면 그 기능을 상실하게 되고 따라서 RAM에 저장된 예약데이타가 상실되어 차후에 전원(B+)인가시 재예약을 해야되는 불편이 있고 사용자의 부주의로 전원코드를 콘덴트에서 분리시킨 경우(제품의 이동 또는 청소등을 위하여) 상기 불편을 감수해야 되며 예약데이타 보존을 위해서는 제품에 지속적으로 전원을 공급시켜야 되므로 소비전력이 증가하는 등의 문제점이 초래되었다.However, such a circuit is to be prepared for instantaneous power failure, so if the power failure lasts for a long time, its function will be lost. Therefore, the reservation data stored in the RAM will be lost. When the power cord is separated from the condenser (for moving or cleaning the product), the above inconvenience is to be taken. In order to preserve reservation data, power must be continuously supplied to the product, resulting in increased power consumption. It became.

본 발명은 마이컴을 통한 예약데이타를 직/병렬변환시켜 전원 오프시에도 데이타 유지가 가능한 메모리에 저장시켜두고 예약시간에 예약데이타를 해독하여 해당 기능제어를 수행할 수 있게 하므로서 기기사용에 편리를 기하고 절전을 도모할 수 있도록한 예약데이타 보존장치를 제공하는데 그 목적이 있는 것으로 먼저 제 2 도를 참조하여 본 발명의 구성부터 설명하면 다음과 같다.According to the present invention, the reservation data through the microcomputer can be converted into serial / parallel, and stored in a memory capable of maintaining data even when the power is turned off. The purpose of the present invention is to provide a reservation data storage device capable of achieving power saving. First, the configuration of the present invention will be described with reference to FIG.

즉, 본 발명의 예약데이타 보존장치는 예약 및 그에 따른 기기 기능제어를 수행하는 마이컴(2)과, 기기의 동작상태가 표시되는 표시부(3)와, 온스크린 표시제어를 수행하는 SDO 제어부(4)와, 영상신호가 표시되는 모니터(5)와, 회로전체에 전원을 공급하는 전원부(6)와, 마이컴(2)으로부터의 예약데이터가 저장되고 전원 오프시에도 그 데이타가 유지되는 기억소자를 포함하는 데이타 보존부(7)로 구성된다.That is, the reservation data storage device of the present invention includes a microcomputer 2 for performing reservation and control of the device function according to the present invention, a display unit 3 for displaying the operation state of the device, and an SDO control unit 4 for performing on-screen display control. ), A monitor (5) on which video signals are displayed, a power supply unit (6) for supplying power to the entire circuit, and a memory device for storing reservation data from the microcomputer (2) and retaining the data even when the power is turned off. It consists of the data storage part 7 which contains.

또한 상기 데이타 보존부(7)는 제 3 도에 도시된 바와 같이, 마이컴(2)에서 출력되는 예약데이타를 병렬데이타로 변환하여 기억수단(9)에 공급하는 직렬-병렬 변환부(8)와, 병렬데이타로 변환 공급된 예약데이타를 저장하는 기억수단(9)와 기억수단(9)에서 출력되는 예약데이타를 직렬데이타로 변환하여 마이컴(2)에 공급하는 병렬-직렬변환부(10)로 구성되고 상기 직렬-병렬변환부(8)는 마이컴(2)으로부터 클록 및 스트로브신호(CLOCK, STROBE) 제어를 받아 데이타 스프트를 수행하는 시프트 레지스터(11, 12, 13)로 구성된다.As shown in FIG. 3, the data storage section 7 includes a serial-parallel conversion section 8 for converting the reserved data output from the microcomputer 2 into parallel data and supplying the data to the storage means 9; To the parallel-serial conversion section 10 which converts the reservation data supplied to the parallel data and the reservation data output from the storage means 9 into serial data and supplies it to the microcomputer 2. The serial-to-parallel converter 8 is composed of shift registers 11, 12, and 13 which perform data shifting under the control of the clock and strobe signals CLOCK and STROBE from the microcomputer 2.

이와 같이 구성된 본 발명 장치에 의한 예약데이타 보존동작을 제 2 도 및 제 3 도를 참조하여 설명하면, 사용자가 도시생략된 통상의 키이조작부 또는 리모콘을 이용하여 예약기능을 수행시킴에 따라 마이컴(2)에서 해당기능에 대응되는 예약데이타를 출력하여 직렬-병렬변환부(8)에 공급하는 한편 표시부(3) 또는 OSD 제어부(4)를 통해 모니터(5)에 현재 키이조작상태와 예약정보를 표시해준다.Referring to Figs. 2 and 3, the reservation data storage operation by the apparatus of the present invention configured as described above will be described with reference to Figs. 2 and 3. As a user performs a reservation function using a conventional key operation unit or a remote controller as shown in Fig. ) Outputs the reservation data corresponding to the corresponding function and supplies it to the serial-parallel conversion section 8 and displays the current key operation status and reservation information on the monitor 5 through the display section 3 or the OSD control section 4. Do it.

직렬-병렬변환부(8)에 공급된 예약데이타는 클록신호(CLOCK) 및 스트로브신호(STROBE)가 인가되는 시프트 레지스터(11, 12, 13)를 거쳐서 병렬데이타(A0~A8)로 변환되고 마이컴(2)의 라이트 인에이블(WRITE ENABLE) 제어에 의하여 기억수단(9)에 저장된다.The reserved data supplied to the serial-parallel conversion section 8 is converted into parallel data A0 to A8 via the shift registers 11, 12 and 13 to which the clock signal CLOCK and the strobe signal STROBE are applied. It is stored in the storage means 9 by the write enable control of (2).

여기서 기억수단(9)은 전원오프시에도 데이타 유지가 가능한 EPROM등의 기억소자로 채용한다. 따라서 기억수단(9)에 저장된 데이타는 전원(VCC) 공급이 중단되어도 유지 가능하므로 기억수단(9)에 저장된 예약데이타는 반영구적이며 상실될 우려가 없다.The storage means 9 is employed as a storage element such as an EPROM capable of retaining data even when the power is turned off. Therefore, the data stored in the storage means 9 can be maintained even when the power supply (VCC) is interrupted, so the reserved data stored in the storage means 9 is semi-permanent and there is no fear of loss.

한편 마이컴(2)이 예약 기능수행을 위하여 예약데이타를 해독하고자 하는 경우에는 기억수단(9)에 출력인에니블(OUT ENABLE) 제어를 하여 기 저장된 예약데이타(D0-D8)를 출력시키고 출력된 예약데이타는 병렬-직렬변환부(10)에서 마이컴(2)의 제어에 따라 직렬데이타로 변환되어 마이컴(2)에 입력(DATA IN)되므로서 예약기능을 실행하게 된다.On the other hand, when the microcomputer 2 wants to decode the reservation data for performing the reservation function, the memory device 9 outputs the ENABLE control to output the pre-stored reservation data (D0-D8). The reservation data is converted into serial data under the control of the microcomputer 2 in the parallel-serial conversion unit 10 and input to the microcomputer 2 to execute the reservation function.

이상에서 설명한 바와 같이 본 발명에 의하면 예약기능을 갖는 전자, 전기제품에서 전원오프시에도 예약데이타가 보존되므로 예약기능 수행에 신뢰를 기할 수 있고 종래와 같이 예약데이타 보존을 위해 상시 전원을 공급할 필요가 없으므로 소비전력의 절약을 도모할 수 있는 효과가 있다.As described above, according to the present invention, since reservation data is preserved even when the power is turned off in electronic and electrical appliances having a reservation function, it is possible to trust the performance of the reservation function and it is necessary to supply power at all times for preservation of reservation data as in the prior art. Therefore, there is an effect that can save power consumption.
