본 발명은 개인 물품분실 경보장치 및 물품관리장치에 관한 것으로, 더욱 상세히는 일정 형태를 갖는 RF 태그를 부착한 물품이 신호수신 및 경보발생수단으로부터 설정거리이상 멀어지면 경보음 또는 진동 및 문자정보를 발생함과 동시에 관리하고자 하는 물품들의 목록이 나타나도록 한 물품분실 경보 및 물품관리 장치에 관한 것이다.The present invention relates to a personal goods loss alarm device and an article management device, and more particularly, when an article with an RF tag having a certain shape is far from a signal receiving and alarm generating means more than a set distance from the alarm sound or vibration and text information. The present invention relates to an item loss alarm and an article management device which displays a list of items to be managed at the same time.

기존의 분실방지기는 개인이 소지하기에는 부피가 크고 한 물품에 대한 분실방지 기능만을 갖고 있어 물품이 다수일 경우 개개의 물품에 따른 그 만큼의 분실방지기가 필요하므로, 이로인해 개인이 휴대하기에 불편할 뿐 아니라 가격이 비싸고 사용상 제한적이어서 분실방지기로서 실용성과 실용성에 문제가 있었고 사용자 개인이 소지하고 휴대할 수 있는 물품관리 장치는 현재 개발되어 있지 못한 실정이다.Existing loss prevention device is bulky for individuals and has loss prevention function for only one item, so if there are many items, it is necessary to prevent loss for each item. In addition, the price is expensive and limited in use, there is a problem in the practicality and practicality as a loss prevention device, and the item management device that can be carried and carried by the individual user has not been developed at present.

일반적으로, 물품의 분실은 소유자의 실수에 의하거나 도난으로 인한 경우가대부분이다. 이런 경우, 소유주는 대개 물품이 분실된 시점으로부터 소정시간이 경과되어 뒤늦게 물품의 분실사실을 알게 되므로, 물품을 되찾기 어렵게 된다. 또한 사회활동에 있어도 관리대상 물품들에 대해 점검하는데 있어서도 상당한 고충을 겪고 있다.In general, the loss of goods is most likely due to the owner's mistake or theft. In this case, the owner usually finds out that the goods are lost after a predetermined time elapses from the time when the goods are lost, making it difficult to recover the goods. There are also significant difficulties in checking the items to be managed in social activities.

이에, 본 발명은 물품이 소유자의 신호수신 및 경보발생수단으로부터 소정거리 이상 멀어지면 경보가 즉각 발생되도록 하여 물품의 분실을 방지하는데 도움을 줄 수 있고, 또 다양한 개인소지 물품들을 수시로 간편하게 체크할 수 있는 물품분실방지 및 물품관리를 제공하는 데에 그 목적이 있다.Thus, the present invention can help to prevent the loss of the goods by immediately causing the alarm to occur immediately when the article is more than a predetermined distance from the signal receiving and alarm generating means of the owner, and also can easily check a variety of personal possession items from time to time The purpose is to provide for the prevention of loss of goods and the management of goods.

이때, 태그(200)는 도 3 내지 도 5에 도시된 바와 같이, 도체(210)를 나선형으로 형성하고 그 양종단(211,212)을 나선형으로 형성된 부분(213)보다 다소 넓게 형성하여 이 도체(210)의 양종단(211,212)이 유전체(220)를 사이로 하여 서로 대향되게 접어서 제작한 것이다.3 to 5, the tag 200 is formed in a spiral shape, and both ends 211 and 212 of the tag 210 are formed slightly wider than the spirally formed portion 213. Both ends (211,212) of the) is produced by folding the dielectric 220 to face each other.

상기와 같이 구성된 태그(200)에서, 도체(210)의 양종단(211,212)은 유전체(220)에 의해 소정 거리만큼 이격되어 있는 바, 그 이격된 거리는 그에 상응하는 정전용량을 가진 캐패시터(Capacitor) 특성을 나타내게 되며, 도체(210)중 나선형으로 형성된 부위(213)는 인덕터(Inductor)의 특성을 나타낸다.In the tag 200 configured as described above, both ends 211 and 212 of the conductor 210 are spaced apart by a predetermined distance by the dielectric 220, and the spaced distance is a capacitor having a corresponding capacitance. The helical portion 213 formed in the conductor 210 represents the characteristic of the inductor.

이에 따라, 신호발생수단(100)을 지닌 RF 태그(200)는 전체적으로 LC직렬공진회로를 형성하며, 이 LC직렬공진회로는 특정한 대역의 주파수에서 공진하는 특성을 나타낸다.Accordingly, the RF tag 200 having the signal generating means 100 forms an LC series resonant circuit as a whole, and this LC series resonant circuit exhibits a characteristic of resonating at a frequency of a specific band.

상기 신호수신 및 경보발생수단(300)은 도 6의 (a)(a)에 도시된 바와 같이, 신호발신수단(100)을 지닌 RF 태그(200)로부터 송출된 RF 신호를 수신받는 수신부(310)와; 이 수신부(310)를 통해 수신된 RF 신호에서 반송파를 제거하여 신호파를 검출하는 복조부(320)와; 이 복조부에서 검출된 신호파를 소정레벨로 증폭하는 증폭부(330)와; 이 증폭부(330)에서 증폭된 신호파의 전류치를 검출하여 검출된 전류치에 따라 경보기를 발생하기 위한 제어신호를 출력하는 신호레벨검출부(340)　및, 상기 신호레벨검출부(340)로부터 출력된 제어신호에 따라 경보음을 발생하거나 경보표시를 행하는 경보부(350)로 구성된다.The signal receiving and alarm generating means 300, as shown in (a) (a) of Figure 6, the receiving unit 310 for receiving the RF signal transmitted from the RF tag 200 having a signal transmitting means 100 )Wow; A demodulator 320 which removes a carrier from the RF signal received through the receiver 310 and detects a signal wave; An amplifier 330 for amplifying the signal wave detected by the demodulator to a predetermined level; A signal level detector 340 for detecting a current value of the signal wave amplified by the amplifier 330 and outputting a control signal for generating an alarm in accordance with the detected current value, and a control output from the signal level detector 340.

상기 전원공급수단(400)은 일예로, 배터리가 될 수 있으며, 이용자가 작동스위치(500)를 조작함에 따라 신호발신수단(100)과 신호수신 및 경보발생수단(300)으로 전원을 인가한다.The power supply means 400 may be, for example, a battery, and applies power to the signal transmitting means 100 and the signal receiving and alarm generating means 300 as the user operates the operation switch 500.

상기한 바와 같이 구성된 본 고안 장치의 동작　예를 도 1내지 도 6을 참조하여 상세히 설명하기로 한다.An operation example of the device of the present invention configured as described above will be described in detail with reference to FIGS. 1 to 6.

먼저, 분실하기 쉬운 물품이나 귀중품 등에 태그(200)를 부착하여 둔다.First, the tag 200 is attached to articles or valuables that are easy to lose.

이때, 수신기에 지정번호가 등록되고, 송신거리가 설정된 태그(200)가 부착되는 각종 물품(일예로, 노트북 컴퓨터, 휴대폰, 지갑 등)은 신호파수신 및 경보발생수단(300)과의 설정거리내에서는 물품관리목록 대상이며, 설정된 거리 밖에 있을시는 분실방지 경보 대상이 되어야 한다.At this time, a specified number is registered in the receiver, and various items (for example, notebook computers, mobile phones, wallets, etc.) to which the tag 200 with a transmission distance is attached are set a distance from the signal wave receiving and alarm generating means 300. It is subject to the goods management list within, and should be the object of loss prevention alarm when it is outside the set distance.

다음, 이용자가 RF 태그(200)의 작동스위치(500)를 온시키면 전원공급수단(400)으로부터 신호발신수단(100)으로 전원이 공급되고, 역시 신호수신 및 경보발생기(300)의 작동스위치(500)를 온시키면 전원공급수단(400)으로부터 신호수신 및 경보발생수단(300)으로 전원이 공급된다.Next, when the user turns on the operation switch 500 of the RF tag 200, power is supplied from the power supply means 400 to the signal transmission means 100, and also the operation switch of the signal reception and alarm generator 300 ( When the 500 is turned on, power is supplied from the power supply means 400 to the signal receiving and alarm generating means 300.

이와같이 전원공급수단(400)으로부터 전원이 공급된 RF 태그(200)내 신호발생수단(100)의 신호파발생부(110)에서는 신호파가 발생되고 반송파발생부(120)에서는 반송파가 각각 발생된다.As such, signal waves are generated in the signal wave generator 110 of the signal generator 100 in the RF tag 200 supplied with power from the power supply means 400, and carriers are generated in the carrier generator 120, respectively.

상기 신호파발생부(110)에서 발생된 신호파는 일정한 진폭 및 주파수를 갖으며, 변조부(130)에서 반송파발생부(120)로부터 입력된 반송파에 실려 RF 신호로 변조된다.　　The signal wave generated by the signal wave generator 110 has a constant amplitude and frequency, and is modulated into an RF signal on a carrier input from the carrier generator 120 in the modulator 130.

여기서, 변조부(130)에 의해 변조되는 RF 신호는 태그(200)의 LC직렬공진회로에 의해 공진할 수 있는 주파수대역을 갖는데, 이 공진주파수는 하기의 수학식1에 의해 구해질 수 있다.Here, the RF signal modulated by the modulator 130 has a frequency band that can be resonated by the LC series resonant circuit of the tag 200. This resonance frequency can be obtained by Equation 1 below.

상기 변조부(130)에서 변조된 RF신호는 증폭부(140)에서 소정의 증폭률로 증폭된 다음 송신부(150)를 매개로 안테나를 통해 공중으로 발신된다.The RF signal modulated by the modulator 130 is amplified by the amplifier 140 at a predetermined amplification rate, and then transmitted to the air through the antenna through the transmitter 150.

상기 신호파발신수단(100)에서 발신된 RF 신호는 물품에 부착된 태그(200)를 거쳐 신호수신 및 경보발생수단(300)으로 수신되고, 신호수신 및 경보발생수단(300)으로 수신된　RF 신호는 수신부(310)를 통해 복조부(320)로 인가되며, 복조부(320)에서 반송파가 제거된 신호파로 복조된다.The RF signal transmitted from the signal wave transmitting means 100 is received by the signal receiving and alarm generating means 300 via the tag 200 attached to the article, and received by the signal receiving and alarm generating means 300. The signal is applied to the demodulator 320 through the receiver 310, and demodulated to a signal wave from which the carrier is removed from the demodulator 320.

상기 복조부(320)에서 복조된 신호파는 증폭부(330)에서 증폭된 다음 신호레벨검출부(340)로　인가되었는데，이때 신호레벨검출부(340)에서는 증폭부(330)로부터 입력된 신호파의 전류치를 검출하여 검출된 전류치에 따라 경보신호를 발생하기 위한 제어신호를 경보부(350)로 인가한다.The signal wave demodulated by the demodulator 320 is amplified by the amplifier 330 and then applied to the signal level detector 340. At this time, the signal level detector 340 receives the current value of the signal wave input from the amplifier 330. The control signal for generating an alarm signal according to the detected current value is applied to the alarm unit 350.

이와같은 태그(200)가 부착된 물품이 신호파발신수단(100)과 신호수신 및 경보발생수단(300)의 사이에 소정 거리이내에 위치하는 경우에는 신호발신수단(100)으로부터 발신된 RF 신호가 태그(200)의 LC공진회로에 의해 공진함에 따라 신호레벨검출부(340)에 의해 검출되는 전류치가 선형적으로 낮아지는 특성을 나타낸다.When the article with the tag 200 is located within a predetermined distance between the signal wave transmitting means 100 and the signal receiving and alarm generating means 300, the RF signal transmitted from the signal transmitting means 100 is Resonance by the LC resonant circuit of the tag 200 exhibits a characteristic that the current value detected by the signal level detector 340 is linearly lowered.

이에 반해, 신호파발신수단(100)과 신호수신　및 경보발생수단(300)의　사이에 소정거리이내에 태그(200)가 부착된 물품이 위치하지 않은 경우에는 신호발신수단(100)으로부터 발신된 RF 신호가 공진하지 않음에 따라 신호레벨검출부(340)에 의해 검출되는 전류치는 태그(200)가 부착된 물품이 신호수신　및 경보발생수단(300)과의 설정된 거리내에 있는 경우에 비해 높은 수치를 나타낸다.In contrast, when the article with the tag 200 is not located within a predetermined distance between the signal wave transmitting means 100 and the signal receiving and alarm generating means 300, the RF transmitted from the signal transmitting means 100 is transmitted. As the signal does not resonate, the current value detected by the signal level detection unit 340 is higher than the case where the article with the tag 200 is within a set distance from the signal reception and alarm generating means 300. .

따라서, 신호레벨검출부(340)는 신호파의 전류치가 소정치 미만일 경우에는 신호를 출력하지 않는 반면, 신호파의 전류치가 소정치 이상이면 경보를 발생하기 위한 제어신호를 출력하도록 설정되어 있다.Therefore, the signal level detection unit 340 is configured not to output a signal when the current value of the signal wave is less than the predetermined value, and to output a control signal for generating an alarm when the current value of the signal wave is more than the predetermined value.

이에 따라, RF 태그(200)가 부착된 물품이 수신 및 경보발생기와 설정거리 내에 있을 경우에는 경보가 발생되지 않은 것에 반해, 태그(200)가 부착된 물품이 수신 및 경보발생기(300)로부터 설정거리이상 벗어나게 되면 경보가 발생되어 이용자가 해당 물품의 분실상태를 신속하게 인지할 수 있게 된다.Accordingly, when the article with the RF tag 200 is within the set distance from the reception and alarm generator, the alarm is not generated, whereas the article with the tag 200 is set from the reception and alarm generator 300. If the distance is more than an alarm is generated so that the user can quickly recognize the lost state of the goods.

한편, 이용자가 태그(200)가 부착된 물품을 수신 및 경보발생기(300)로부터 설정거리 밖으로 놓을 경우에는 수신 및 경보발생부에 있는 기능키를 작동하거나 작동스위치(500)를 오프시킴으로써, 경보가 발생되는 것을 방지 할 수 있다.On the other hand, when the user puts the article with the tag 200 out of the set distance from the receiving and alarm generator 300, by operating the function key in the receiving and alarm generating unit or by turning off the operation switch 500, It can be prevented from occurring.
