目前,用于墙壁防凿洞的探测器种类不少,有灵敏度很高的振动式探测器,但它克服不了库外过汽车或施工等引起的误报警;有国外进口的振动探测器,但它必须在上下振幅达到一定程度才产生动作,而对于凿、钻等破坏均无动于衷。 为达到真正的实用水平,北京开摩微电技术中心根据“固体声频传导”

At present, there are many types of detectors for wall bored holes and vibrating detectors with high sensitivity. However, it can not overcome the false alarms caused by cars or construction outside the library. There are vibration detectors imported from abroad but It must be up and down amplitude to a certain extent before the action, but for chisel, drill and other damage are indifferent. In order to achieve a real practical level, Beijing Kaifu Microelectronics Technology Center under the “solid-state audio conduction”
