An infrared transmitter 103 having a waveform generator 102 and a signal synthesizer 101 for deforming and emitting the waveform;

TV 수상기의 전원의 온/오프를 판별하기 위한 전류 검출부(105)와 시청자의 근접 여부를 검출하기 위하여 초음파를 생성하는 송신 증폭 정형부(107) 및 이를 송수신하기 위한 초음파 송수신 센서(108)와 입력 신호를 증폭하기 위한 수신증폭 정형부(107)와 현재 상황을 출력하기 위한 LED 표시장치(109), 경보용 부저(111) 및 증폭부(110), 검출거리 출력부(112)와 사용자가 감지거리 제한 입력부(115)와 지연시간 설정부(116), 제어설정부(117)를 조작하여 설정치를 가지는 주제어 장치(100)와 외부 기억 장치부(114)로 이루어 진다.Input with a current detector 105 for determining whether the power of the TV receiver is on or off and a transmission amplification shaping unit 107 for generating ultrasonic waves for detecting proximity of a viewer and an ultrasonic transceiving sensor 108 for transmitting and receiving them. Receive amplification shaping unit 107 for amplifying the signal, LED display unit 109 for outputting the current situation, alarm buzzer 111 and amplifying unit 110, detection distance output unit 112 and the user senses The main controller 100 and the external memory unit 114 having a set value are operated by operating the distance limit input unit 115, the delay time setting unit 116, and the control setting unit 117.

이하, 상기와 같이 이루어지는 본 발명의 작용을 상세히 설명하기로 한다.Hereinafter, the operation of the present invention made as described above will be described in detail.

본 발명은 TV수상기의 적외선 리모콘을 동작하여 온/오프 신호를 발생시켜 본 장치의 적외선 수신부(104)를 통하여 외부 메모리부(114)에 저장하고, 저장된 온/오프 신호를 적외선 송신부(103)를 통하여 출력하여 TV전원의 온/오프를 제어 한다.The present invention generates an on / off signal by operating an infrared remote controller of a TV receiver, and stores the on / off signal in the external memory unit 114 through the infrared receiver 104 of the apparatus, and stores the stored on / off signal in the infrared transmitter 103. It outputs through to control TV power on / off.

TV 온/오프를 제어하기 위해선 시청자가 TV 수상기로의 근접여부를 측정하기 위하여 주제어 장치(100)에서 송신 증폭 정형부(107)를 통하여 방사 압력을 높여 일정주기로 초음파 송수신 센서(108)를 통하여 초음파를 방사하고 근접 시청자에게 반사되어 돌아온 초음파를 다시 초음파 송수신 센서(108)로 인입하여 수신증폭 정형부(106)에서 미약한 초음파를 증폭하여 일정 레벨이상으로 입력되는 신호를 주제어 장치(100)에서 판단하여 송신시의 시간과 수신시의 시간차를 구하여 이를 거리로 환산하고 사전에 감지거리 제한부(117)를 통하여 입력된 수치와 비교하여 이보다 긴 경우에는 그 값을 버리고 수치가 짧은 경우에는 검출거리 표시부(112),LED표시장치(109)및 경고용 부저(111)를 통하여 경고 한다.In order to control the TV on / off, the viewer increases the radiation pressure through the transmission amplification shaping unit 107 in the main controller 100 to measure the proximity to the TV receiver. Radiates and returns the ultrasonic waves reflected back to the near viewer to the ultrasonic transceiving sensor 108 to amplify the weak ultrasonic waves in the reception amplifier shaping unit 106 to determine a signal input at a predetermined level or more by the main controller 100. To calculate the time difference between the time of transmission and the time of reception, convert it to distance, compare it with the value input through the sensing distance limiter 117 in advance, and if it is longer than this, discard the value, and if the value is short, the detection distance display part 112, the LED display device 109 and the warning buzzer 111 to warn.

또한 전류 검출기(105)를 통하여 TV의 온/오프 여부를 판단하여 TV가 온 되었을 경우에만 시청자의 근접 시청여부를 판단하여 TV 전원을 적외선 송신부(103)를 통하여 제어한다.In addition, the current detector 105 determines whether the TV is on or off, and determines whether the viewer is in close proximity when the TV is turned on, and controls the TV power supply through the infrared transmitter 103.

이어, 첨부된 도2는 본 발명의 실시예에 따른 TV수상기의 근접 시청 제한 장치를 설명하기 위한 흐름도로서, 먼저 초기 상태를 입력받기 위해서 TV수상기의 리모콘 온/오프 SW 동작시켜(201) 수신 장치에서 온/오프 SW 신호를 입력받아(202) 온/오프 입력 신호를 메모리에 저장(203),기억(204)시키고, 시청자가 초기에 경고 모드 설정을 하기 위하여 경고 할 감지 거리를 메모리에 저장하고(206) 시청자가 입력받은 거리 내에서 어느 시간 만큼 있을시 경고 할 지연 시간을 입력받아(207) 메모리에 저장하여(208) 초기화를 마친다.Next, FIG. 2 is a flowchart illustrating an apparatus for limiting proximity viewing of a TV receiver according to an embodiment of the present invention. First, in order to receive an initial state, a remote control on / off SW operation of a TV receiver is performed (201). Receives the on / off SW signal from 202 and stores the on / off input signal in the memory (203) and memory (204), and stores the sensing distance in the memory to alert the viewer to set the warning mode initially. In step 206, the viewer receives a delay time for warning when there is a certain time within the input distance (207) and stores in the memory (208) to complete the initialization.

상기 초기 설정 모드 입력 과정 후 동작에 대해서 설명하기로 한다.Operation after the initial setting mode input process will be described.

전류 검출기를 통하여 TV 수상기의 온/오프 여부를 검출하여 검출될 경우에만(209) 40Khz의 주파수를 주제어 장치(100)에서 발생시켜(210) 기 설정된 시간마다 송신증폭 정형부에(107)에서 출력을 증폭시켜 초음파 송수신 센서(108)을 통하여 방사하고 주제어 장치(100)내의 내부 타이머를 동작시키고 방사된 파형이 시청자에게 맞고 되돌아온 초음파의 수신 여부를 검출한다.(213)Only when it is detected by detecting whether the TV receiver is turned on or off through a current detector (209), a frequency of 40 kHz is generated in the main controller 100 (210) and outputted from the transmission amplification shaping unit 107 every predetermined time. By amplifying and radiating through the ultrasonic transceiving sensor 108 and operating an internal timer in the main control device 100, the radiated waveform hits the viewer and detects whether or not the ultrasonic wave is returned.

검출되지 않은 경우에는 다시 주제어 장치(100)에서 40Khz의 주파수를 생성하여 위 과정을 반복하고 검출된 경우에는 타이머의 시간을 정지시켜 초음파의 수신 시간을 검출한다.(214) 위 과정을 통하여 타이머의 정지시간과 시작시간을 구하여 동작시간을 구하고(215) 이를 초음파 속도에 따른 검출거리로 환산하여(216) 초기화 동작 과정중 입력받은 감지거리와 비교하여(217) 측정거리가 길 경우에는 다시 주파수 발생시점(210)으로 돌아가고 짧을 경우에는 주의 경고음을 경보용 부저(111)을 통하여 발생시키며 동작 시간을 누적하여 기입력된 지연시간(207)과 비교하여 시청자가 TV 수상기앞에 지연시간 보다 오래 앉아 있는 경우(210) 기 입력된 TV 수상기의 온/오프 신호를(202) IR송신부(103)를 통하여 재생하여 TV의 전원을 차단한다(220). 차단 여부는 전류 검출기(105)를 통하여 다시 한번 확인 한다(221).If not detected, the main controller 100 again generates a frequency of 40 KHz and repeats the above process, and if detected, stops the timer time and detects the reception time of the ultrasonic wave. (214) The operation time is obtained by obtaining the stop time and the start time (215), and converted into the detection distance according to the ultrasonic speed (216). The frequency is generated again when the measurement distance is long compared with the detection distance input during the initialization operation (217). If the return to the time point 210 is short, the warning beep is generated through the alarm buzzer 111, and the viewer is sitting longer than the delay time in front of the TV set in comparison with the delay time 207 inputted by accumulating the operation time. The power source of the TV is cut off by reproducing the on / off signal of the TV receiver inputted through the IR transmitter 103 (202). The blocking is again checked through the current detector 105 (221).

본 발명은 상기의 과정을 통하여 시청자가 근접거리에서 시청하는 것을 제한할 수 있다.According to the present invention, the viewer can restrict viewing at close range.

이상에서 설명한 바와 같이 본 발명은 시청자와 TV 수상기와의 거리를 송수신 겸용 초음파 센서를 사용하여 측정하고 이를 측정거리와 기입력된 감지거리와 비교하여 감지된 거리가 짧고 기 입력된 지연시간보다 긴 경우를 검출하기 위한 주제어장치를 구비하고 있으며 시청자에게 경보음을 통하여 경고할 수 있는 출력장치와 시청자가 재차 반복적으로 근접거리에서 검출될 경우 TV리모콘의 온/오프 적외선 신호를 대신하여 온/오프 신호를 재생하는 IR 송신부를 통하여 TV 수상기의 전원을 제어하는 장치를 제공하여 시청 위치를 감지거리보다 멀게끔 유도하여 TV수상기의 근접 시청을 제한하여 TV수상기에서 발생되는 유해 전자파와 시청자의 시력저하를 방지하는데 효과가 있다.As described above, the present invention measures the distance between the viewer and the TV receiver using an ultrasonic sensor for both transmission and reception, and compares it with the measured distance and the input detection distance, and the detected distance is shorter than the input delay time. Equipped with a main control device for detecting the signal, and an output device that can warn the viewer through an alarm sound and on / off signal in place of the on / off infrared signal of the TV remote control when the viewer is repeatedly detected in close proximity. Provides a device that controls the power of the TV receiver through a reproducing IR transmitter to induce the viewing position farther than the sensing distance, thereby limiting near-viewing of the TV receiver to prevent harmful electromagnetic waves generated by the TV receiver and deterioration of the viewer's vision. It works.
