방범·방재경보기.Crime prevention and disaster prevention alarm.

2. 발명이 해결하려고 하는 기술적 과제2. Technical Challenges to be Solved by the Invention

본 발명에서는 전압출력형 센서로부터 수신되는 신호에서 정상 및 이상상태 뿐만아니라 전송선로의 단선상태까지 감지하는 회로를 구현한다.In the present invention, a circuit for detecting not only normal and abnormal states but also disconnection states of transmission lines in a signal received from a voltage output type sensor is implemented.

3. 발명의 해결방법의 요지3. The point of the solution of the invention

본 발명의 센서접속회로는 센서로부터 전송선로를 통하여 들어오는 신호가 3가지 레벨상태를 나타내게 하고 각 레벨 상태에 따라 이상감지부에서는 센서의 이상 유무를 감지하고 단선감지부에서는 전송선로의 단선을 감지한다. 또한 시험신호입력부를 두어 시험자가 임의로 센서 수신기능 및 전송선로 단선 체크기능을 테스트한다.In the sensor connection circuit of the present invention, a signal coming from a sensor through a transmission line is displayed at three levels, and the abnormality sensing unit senses an abnormality of the sensor according to each level state and detects a disconnection of a transmission line at the sensing line unit . In addition, a test signal input unit is provided so that the tester can arbitrarily test the sensor receiving function and the transmission line check function.
