首先， 对本发明的起重机的安全监控装置的基本构成方式进行说明。 根据本发明 的原理， 本起重机的安全监控装置包括： 测距单元， 其对起重机的周围环境进行检测， 该测距单元根据检测到的设定目标 （比如， 人） 而生成相应的距离信息， 并将该距离 信息输出， 此时， 测距单元输出的信息为目标与测距单元之间的距离； 处理单元， 其 与测距单元通信连接以接收来自测距单元的距离信息， 并且与起重机的主控制器通信 连接以读取主控制器中的当前作业参数信息， 处理单元根据上述距离信息和当前作业 参数信息确定目标是否处于起重机的作业范围内， 并生成相应的输出信号； 以及报警 单元， 其与处理单元通信连接以接收来自处理单元的输出信号， 该报警单元响应于接 收到的输出信号而执行预定的操作 （例如， 发出音频报警信号）。 通过上述这种安全监控装置， 能够实现主动实时的安全监控。 安全监控装置的测 距单元能够自动地实时检测是否有人进入了危险区域内（作业半径范围内）， 并将距离 信息传送给处理单元； 处理单元一方面接收距离信息， 同时还从起重机的主控制器处 读取相关的作业信息， 并根据预先编好的算法对两种信息进行处理， 进而输出相应的 控制信号， 以控制报警单元的操作。 由此， 能够实时检测作业半径内是否有人员出现， 并及时发出警报， 以提醒现场人员远离危险的作业区域。 根据本发明， 测距单元可以布置在起重机附近的地点或者安装至起重机上的任何 适当位置处， 只要便于对作业范围内的人员进行检测即可。 例如， 可以布置在起重机 的周围， 或者安装至起重机的回转机构、 吊臂、 控制室等。 处理单元和报警单元的布 置位置也十分灵活， 可以布置在起重机的任何适当位置处， 甚至可以作为远程操作单 元而与起重机分离地设置。 并且， 测距单元的数目和类型也可以根据操作需要而进行 适当的选择， 这些将在下面结合具体实例进行说明。 具体地， 图 1中示出了根据本发明一个实施方式的安全监控装置的原理框图。 该 安全监控装置主要包括： 测距单元、 处理单元、 蜂鸣器、 LED警示灯和外部警示声讯 器。 在所示的原理图中， 蜂鸣器、 LED警示灯和外部警示声讯器构成了上述的报警单 元， 测距单元通过一个单独的电源模块与处理单元相连， 电源模块用于为整个安全监 控装置供电。 在其他实施方式中， 安全监控装置也可以与起重机的主控制器共用一个 电源。 图 2 中示出了根据本发明一个实施方式的安全监控装置布置在起重机上的示意 图， 其中仅示出了起重机的局部。 在图 2 所示的实例中， 测距单元附接至起重机 10 的回转机构 11，具体包括相对于起重机 10的吊臂 12的纵轴线 A对称布置的一对测距 传感器 1、 3， 如图 2所示， 这一对测距传感器 1、 3与回转机构 11的回转中心的连线 均相对于纵轴线 A成预定角度 α。 该预定角度 α的范围可以任意选取， 只要保证形成
的检测区域能够完全覆盖吊臂 12前方的区域即可。 由此， 这对测距传感器 1、 3能够 随着回转机构 11的回转运动在其间的 2α角度范围进行检测，其主要对吊臂 12前方区 域的作业半径进行重点监测。 进一步优选地， 测距单元可以包括布置在回转机构 11 周围的多个测距传感器， 这样无论回转机构 11转动到什么位置（即无论吊臂指向什么 位置）， 都能够在 360°的范围内进行目标检测。 此外， 需要说明的是， 图 2的实施方 式中的一对测距传感器 1、 3并非必须对称地布置， 也可以根据实际操作需要对两个测 距传感器 1、 3的角度进行调整。 具体地， 测距单元可以选自多种类型的测距传感器， 例如： 红外测距传感器、 激 光测距传感器、 超声波测距传感器或雷达测距传感器等。 进一步地， 在采用测距传感器的情况下， 安全监控装置的处理单元 2可以具有将 从主控制器 4中读取的当前作业参数信息转换成相应的作业半径的计算模块 （图中未 示出）。并且， 处理单元 2还具有将计算出的作业半径与来自测距单元的距离信息相比 较的比较模块（图中未示出）， 该比较模块根据比较结果生成相应的输出信号， 以便控 制报警单元的操作。 更具体地， 处理单元 2读取的当前作业参数信息可以包括： 起重机吊臂的角度、 起重机吊臂的伸出长度等。 通过这些参数信息， 计算模块可以计算出相应的作业半径 信息。 优选地， 如图 1的框图中所示， 本发明的安全监控装置的报警单元包括设置在起 重机 10的控制室 13中的蜂鸣器和警示灯 （图中未示出） 以及设置在控制室外部的声 讯警示器 5。 通过控制室 13 内部的蜂鸣器和警示灯， 控制室 13 内的操作人员可以及 时获知有人进入了危险作业区域内， 从而调整吊臂 12的操作， 以避免发生事故； 与此 同时，控制室 13外部的声讯警示器 5则可以提醒操进入危险区域的人员及时原理该作 业区域。 由此， 能够同时提醒起重机的操作人员和外部人员， 提醒双方注意， 从而更 好地防范事故的发生。 在一个实施方式中， 上述的蜂鸣器、 警示灯和处理单元 2可以集成在一起， 构成 一个共同的操作单元。 并且， 进一步地， 处理单元 2还可以与起重机 10的主控制器 4 集成在一起。 下面， 对安全监控装置的操作方式进行简要说明， 其中安全监控装置以距离信息 为比较对象进行监控。
如果有人、 车辆等进入测距单元的感应范围内时， 测距单元向处理单元发出检测 信息（如所测得的距离数据），处理单元则立即读取起重机主机控制器中的工况参数 (如 吊臂的角度、长度等），并通过处理单元内部的计算模块计算出此时起重机的作业半径， 进而通过比较模块比较测得的距离数据和计算出的作业半径， 如果所测距离小于作业 半径， 则启动报警单元进行报警， 比如启动内置的蜂鸣器、 LED警示灯和外部警示声 讯器， 由此起到自动安全警示的作用。 由上述说明可以看出， 本发明的安全监控装置可以通过感应检测和数据对比的方 法， 能实时确定起重机不同工况下的吊臂的作业半径， 并且能及时发现起重机不同工 况作业时作业半径内是否有人或者车辆等出现， 从而能对试图进入起重机吊臂作业半 径内的人、 车辆起很好的安全警示作用。 并且， 本安全监控装置的结构简单， 安装方 便， 制造成本低， 具有良好的应用价值和广泛的适用性。 此外， 根据本发明的原理， 还提供了包括上述安全监控装置的起重机。 当然， 需 要说明的是， 本发明的安全监控装置不仅能应用于起重机， 也可以适用于其他类似的 大型工程设备， 例如： 混凝土泵车、 高空作业车、 消防车。 本发明的安全监控装置例 如可以装在设备的作业臂上。 同时， 根据本发明的原理， 还提供了一种起重机的安全监控方法， 其包括以下步 骤： a) 通过测距单元对起重机 10的周围空间进行检测， 并根据检测到的设定目标来 生成相应的距离信息， 进而将距离信息输出； b) 通过与测距单元以及起重机 10的主控制器 4通信连接的处理单元 2接收来自 测距单元的距离信息， 并从主控制器 4读取起重机 10的当前作业参数信息，进而比较 检测信息与当前作业参数信息， 以确定物理是否处于起重机 10的作业范围内， 随后根 据比较结果生成相应的输出信号； 以及 c) 通过与处理单元 2通信连接的报警单元来接收来自处理单元 2的输出信号， 并 响应于该输出信号而执行预定的操作。 进一步地， 根据本发明的起重机安全监控方法， 其中， 在步骤 b)中， 处理单元 2 在比较检测信息与当前作业参数信息之前， 将当前作业参数信息转换成相应的作业半 径； 处理单元在将当前作业参数信息转换成作业半径之后， 将距离信息与该作业半径 进行比较， 其中， 在目标与测距单元之间的距离小于或等于作业半径的情况下， 处理 单元输出报警信号。
以上仅为本发明的优选实施例而已， 并不用于限制本发明， 对于本领域的技术人 员来说， 本发明可以有各种更改和变化。 凡在本发明的精神和原则之内所作的任何修 改、 等同替换、 改进等， 均应包含在本发明的保护范围之内。
