Abstract: front page image
(EN)The present invention relates to an obstacle detecting device using a prescaler and a detecting method. The obstacle detecting device of the present invention includes: a sensor strip having a varying capacitance value according to the proximity of an obstacle; an RF oscillator connected to the sensor strip; a prescaler for dividing an oscillation frequency of the RF oscillator by a set ratio; and a Micro Controller Unit (MCU) for controlling the operation of the RF oscillator and receiving a divided signal from the prescaler. Since an obstacle detecting device according to the present invention does not include a local oscillator, a mixer, a PLL, and a loop filter, its configuration is simple, product price is lowered, and malfunction possibility is drastically reduced. Moreover, since the proximity of an object is determined by calculating a reference frequency in each set period while an RF oscillator operates, the RF oscillator does not need to be tuned, thereby drastically increasing product productivity.
(FR)L'invention concerne un dispositif de détection d'obstacle qui utilise un pré-échelonneur, ainsi qu'un procédé de détection. Le dispositif de détection d'obstacle comprend : une bande de détection possédant une valeur de capacitance variable en fonction de la proximité d'un obstacle ; un oscillateur RF connecté à la bande de détection ; un pré-échelonneur afin de diviser la fréquence d'oscillation de l'oscillateur RF selon un rapport prédéfini ; et une micro-unité de commande (MCU) afin de commander le fonctionnement de l'oscillateur RF et de recevoir un signal divisé du pré-échelonneur. Etant donné que le dispositif de détection d'obstacle de la présente invention ne comprend pas d'oscillateur local, de mélangeur, de boucle d'asservissement de phase ni de filtre de boucle, sa configuration est simple, le coût de production est réduit, et les risques de panne sont drastiquement réduits. En outre, étant donné que la proximité d'un objet est déterminée en calculant une fréquence de référence dans chaque période prédéfinie pendant le fonctionnement de l'oscillateur RF, ce dernier n'a pas besoin d'être ajusté, ce qui accroît fortement la productivité du produit.
(KO)본 발명은 프리스케일러를 이용한 장애물 감지장치 및 감지방법을 개시한다. 본 발명의 장애물 감지장치는 장애물의 근접여부에 따라 정전용량값이 달라지는 센서스트립; 상기 센서스트립에 연결된 RF발진기; 상기 RF발진기의 발진주파수를 설정비율로 분주하는 프리스케일러(prescaler); 상기 RF발진기의 동작을 제어하며, 상기 프리스케일러에서 분주된 신호가 입력되는 마이크로컨트롤러유닛(MCU)을 포함한다. 본 발명에 따른 장애물 감지장치는 로컬발진기, 믹서, PLL, 루프필터 등을 사용하지 않으므로 구성이 간단하여 제품단가를 낮출 수 있고 제품의 오작동 가능성을 크게 줄일 수 있다. 또한 RF발진기가 동작하는 동안 기준주파수를 설정 주기마다 산출하여 장애물 근접여부를 판단하므로 RF발진기를 튜닝하지 않고도 사용할 수 있어 제품 생산성을 크게 높일 수 있다.
