Abstract

본 발명은 주로 승용차의 도난을 방지하기 위한 도난 경보시스템에 관한 것으로 최근에 보급되기 시작한 차량용 도난 경보기가 몇가지 문제점을 안고 있으며 가장 큰 문제점은 그 설치를 위하여 반드시 차량의 대쉬 보드(dash board)나 바디에 구멍을 내는 등, 차체의 원상을 훼손시켜야만 한다는 문제의 해결을 위하여 차량에 일체의 손상을 주지않고 설치가능하도록 함에 목적이 있으며, 다른 목적은 다수의 제어기능 및 쎈서의 사용이 가능하도록하여 다기능화 할 수 있도록 함으로써 차량용 도난 경보기의 품질을 고급화할 수 있도록 함에 있고 이러한 목적이 비교적 간결하며 신뢰성이 높은 경제적 구조에 의하여 달성될 수 있도록 함에 있는 것이다.The present invention mainly relates to a burglar alarm system for preventing theft of a passenger car, the vehicle burglar alarm has recently started to spread some problems, the biggest problem is necessarily the dash board or body of the vehicle for installation In order to solve the problem of having to damage the original body of the vehicle, such as making holes in it, the purpose is to be able to install it without any damage to the vehicle, and another purpose is to enable the use of multiple control functions and sensors. In order to improve the quality of car burglar alarms, the objective is to be achieved by a relatively simple and reliable economic structure.

본 발명에서는 이를 위하여 고주파수, 발신에 의한 무선 통신 방식이나 별도의 전선 접속에 의하지 않고 기왕에 설치되어 있는 단한개의 전원선을 이용하여 교신하고, 상기 전원선에 접속된 감지기측과 경보부측에는 각각 다수의 독립된 신호의 수, 발이 가능한 톤인코더와 톤디코더를 접속하여서 된 것이다.In the present invention, the communication using a single power supply line installed in the past without using a high-frequency, outgoing wireless communication method or a separate wire connection, and each of the detector side and the alarm unit connected to the power supply line This is done by connecting the number of independent signals and tone decoders that can be generated and connected.
