请参阅图 1-5 所示, 本发明安全操控振动感应报警系统主要包括振动 感应传感装置 1、 数据处理装置 2、 报警输出驱动电路 3和警报装置 4。 本发明可应用于任何需要持续持握操作的设备, 振动感应传感装置 1 安装于该设备的持握部上, 且振动感应传感装置 1布满该持握部, 例如,安 装于汽车、 轮船、 火车、 地铁、 飞机、 起重机或机床等设备的方向盘或操 作手柄上。 振动感应传感装置 1 采用压电薄膜振动传感系统, 可根据安装设备要 求制成各种形态, 例如制成套状、 条状或潜入式,外表面材质可选用橡胶、 皮革、 化纤织物、 天然织物、 碳纤织物、 金属镀膜、 金属导电织物或塑料 等。 振动感应传感装置 1内部设有感应器,感应器可为振动感应器, 材质可 为压电薄膜片。 振动感应传感装置 1 的感应器发出的电信号经检测、 放大 后, 传输给数据处理装置 2。 数据处理装置 2 由开关电路、 单片机等组成, 接收并分析振动感应传 感装置 1 传送的信号, 并根据需要, 在设备的持握部脱离或放松持握时接 通报警输出驱动电路 3。 较佳的, 还可以根据设备情况, 将数据处理装置 2 与设备的自动保护系统控制电路相连接。

传统液压或气压的传感装置受材料的限制很大, 随着时间和使用频率 的增加, 材料老化, 弹力下降, 密封效果降低, 弹性较好的低压液压胶管 的使用寿命一般在 1至 2年, 这些都大大制约了液压、 气压等传导方式的 发展。 而振动传感技术, 以振动传感器 PVDF压电薄膜元件 LDT0-028K及 LDTM-028K, LDT 1-028 为例, 与传统液压或气压传感装置相比有如下优势:
1、 LDT0做为振动传感器, 将压接端子引脚穿过印刷线路板, 焊在 PCB 板另一面的导电图形上, 用电荷放大器检出来自振动台 (振动感应传感装 置) 的输出信号;
2、 LDT0做为柔性开关, 采用电荷放大器获得 "开路" 电压灵敏度,可 测得传感器端部变形所产生的输出, 2麵振动变形足以产生 7V的电压;
3、 LDT0的频率响应, 将 480pF左右的源电容接上一个阻性输入负载, 会呈现高通滤波特性, 用电子噪声源产生宽带信号, 可测出各种负载阻抗 效应并确定 R- C滤波器的- 3dB点;
4、 LDT0不同自由端长度, 用简单固定方式, 可测得不同自由端长度时 的振动灵敏度。 本发明采用微振动传感技术, 灵敏度高, 在操控者不启动机械设备的 情况下, 设备自身微振动信号数据就已经很清晰, 当设备运行时操作者对 操作部位因操作产生的振动足以提供更强的数据; 本发明产品精准度高,且 数据采集中可以采集到非常微弱的信号数据和非常小幅度的数据变化; 体 积小, 只有 1至 2毫米的厚度, 使用方便; 寿命长, 在正常情况下使用可 以达到 7年以上的使用寿命。 以上所述, 仅是本发明的较佳实施例而已, 并非对本发明作任何形式 上的限制, 虽然本发明已以较佳实施例揭露如上, 任何熟悉本专业的技术 人员, 当可利用上述揭示的技术内容作出些许更动或修饰为等同变化的等 效实施例, 均仍属于本发明技术方案的范围内。
