摩托车被盗一直困扰着骑车族,安装报警器能有效地防止被盗。市售的报警器价格比较昂贵而且报警灵敏度不是过高就是太低,实在让人不放心。笔者几经尝试终于制作成功了一个报警器,可靠性高、误报率低,其核心部分采用了天津特新电子厂生产的ND-1振动位移传感器。它是一种集振动和位移检测于一体的全方位固态控制器件,传感部分采用先进的固态加速检测器件,既对振动有很高的灵敏度,又对声音信号抑制,具有很强的抗干扰性,而且器件工作在固态检测方式故不存在机械疲劳、灵敏度降低、温度影响
Stolen motorcycle has been bothering cyclists, the installation of the alarm can effectively prevent theft. The alarm is more expensive and commercially available alarm sensitivity is not too high or too low, it really makes you feel at ease. After several attempts to finally make a success of an alarm, high reliability, low false alarm rate, the core part of the use of the Tianjin special new electronics factory production ND-1 vibration displacement sensor. It is a set of vibration and displacement detection in one of the all-solid-state control device, the sensing part of the advanced solid-state acceleration detection device, both high sensitivity to vibration, but also the voice signal suppression, with strong anti-interference Sex, and the device is working in the solid state detection method so there is no mechanical fatigue, lower sensitivity, temperature effects
