本实用新型的工作原理是：电路中的R1~R3、C1、C2构成桥式检测电路。芯片IC1、发光二极管D2和单向晶闸管Q1组成报警控制电路。发光二极管D2作为报警指示灯，IC2、R5、R6、V1、V2组成声响放大电路。C3～C5均为抗干扰电容。当电缆信号线A正常时，ICl第2脚电位高于第3脚，输出低电平，单向晶闸管Q1截止，发光二极管D2不导通，报警电路失电不工作。当电缆信号线A被盗窃者弄断或者遇到自然灾害导致的断裂时，芯片IC1的第3脚电位高于第2脚电位，因此第1脚输出高电平，发光二极管D1导通，同时单向晶闸管Q1导通。从而使得报警电路得电工作，喇叭B发出响亮的报警声音，形成声光报警。 The working principle of the utility model is: R1~R3, C1 and C2 in the circuit form a bridge detection circuit. Chip IC1, light-emitting diode D2 and one-way thyristor Q1 form an alarm control circuit. Light-emitting diode D2 is used as an alarm indicator light, and IC2, R5, R6, V1, V2 form a sound amplifier circuit. C3 ~ C5 are anti-interference capacitors. When the cable signal line A is normal, the potential of the second pin of ICl is higher than that of the third pin, the output is low level, the one-way thyristor Q1 is cut off, the light-emitting diode D2 is not conducting, and the alarm circuit does not work when it loses power. When the cable signal line A is broken by a thief or broken by a natural disaster, the potential of pin 3 of the chip IC1 is higher than that of pin 2, so pin 1 outputs a high level, and the light-emitting diode D1 is turned on, and at the same time The one-way thyristor Q1 is turned on. As a result, the alarm circuit is energized to work, and the loudspeaker B emits a loud alarm sound, forming an audible and visual alarm.
