优选地, 上述实施例中, 命令发送单元 1 可为一种遥控装置, 所述遥 控装置与支腿控制器 2通过有线或无线方式进行连接。 例如: 所述命令发 送单元包括遥控装置和遥控接收器, 所述遥控装置与所述遥控接收器可通 过有线或无线方式连接, 所述遥控接收器与所述支腿控制器可通过有线或 无线方式连接。
需要说明的是, 在该技术方案中, 采用有线连接的方式, 有利于提高 信号传输的稳定性; 采用无线连接的方式, 有利于进一步远离工程机械, 而不必受到线缆等的长度的限制, 从而避免在支腿 4 的运动过程中打到操 作人员, 提升操作的安全性。
进一步来讲, 如图 3所示的遥控装置 10, 该遥控装置 10上设置有命令 接收装置, 所述命令接收装置配置为根据所接收到的动作指示生成所述支 腿控制命令。 例如, 命令接收装置感应动作指示, 并根据所述动作指示生 成支腿控制命令。 本实施例中, 所述动作指示可为预设的操作动作。
例如: 在该技术方案中, 这里的命令接收装置可以为物理按键、 操作 杆、 语音接收识别装置、 图像采集识别装置、 触摸屏、 键盘等多种形式中 的任意一种或多种, 以便于用户的命令输入。
上述实施例中, 所述命令接收装置包括动作指示输入器件, 每个动作 指示输入器件对应于至少两个支腿设置, 并配置为根据输入的动作指示生 成相应的支腿控制命令。 其中, 所述支腿控制命令中包含有用于确定与被
控制支腿相对应电磁阀的支腿信息。
例如: 这里, 可以设置于所述命令接收装置上的按钮作为动作指示输 入器件。 在上述任一技术方案中, 命令接收装置包括多个按钮 102, 每个按 钮 102对应于多个支腿; 在感应到针对指定按钮 102的操作动作时, 生成 相应的支腿控制命令; 支腿控制命令中包含有支腿信息, 支腿控制器 2根 据支腿信息确定对应的电磁阀 3 ,以控制对应于指定按钮 102的多个支腿 4。
在该技术方案中, 在遥控装置 10上设置多个按钮 102, 并为每个按钮 102预设置对应的功能,比如某个按钮 102对应于图 1所示的工程机械的第 三支腿 43和第四支腿 44的展开, 则当用户按下该按钮 102后, 将对上述 两个支腿进行展开操作。 通过对发送的支腿控制命令的辨识, 以便区分出 不同的功能按钮, 并确保准确地控制相应的支腿 4。
优选地, 上述各实施例中, 所述命令接收装置包括两个动作指示输入 器件, 所述动作指示输入器件与处于同侧的支腿对应设置。
例如: 此处, 所述动作指示输入器件以按钮为例, 在上述任一技术方 案中,命令接收装置包括两个按钮,每个按钮对应于处于同侧的多个支腿 4。
在该技术方案中, 通过安装支腿 4所处位置的不同, 将支腿 4分为两 组, 便于适应不同的工况。
在上述任一技术方案中, 在多个按钮 102 同时感应到操作动作时, 生 成针对所有支腿 4的支腿控制命令。
在该技术方案中,每个按钮 102可以分别控制多个支腿 4, 比如某一侧 的支腿 4,而多个按钮 102同时进行操作时,可以对所有的支腿 4进行控制, 从而实现同步操作。
根据本发明的又一方面, 还提出了一种工程机械, 包括如上述的任一 技术方案中所述的支腿控制系统。
上述所实施例中, 所述工程机械包括臂架装置和多个支腿。 其中, 所
述命令发送单元与所述臂架装置连接, 所述命令发送单元设置有用于在所 述臂架装置和所述支腿控制器之间进行切换控制的切换装置。
例如: 所述工程机械包括臂架装置和多个支腿, 如两腿、 三腿、 四腿 不等; 命令发送单元为臂架遥控器, 该臂架遥控器上设置有上述的功能按 钮 102, 还可以设置有如图 3所示的切换装置 104, 当切换装置 104处于第 一状态位时, 臂架遥控器根据感应到的操作动作, 向臂架装置发送臂架控 制命令, 当切换装置 104处于第二状态位时, 臂架遥控器根据感应到的操 作动作, 向相应的多个支腿 4发送支腿控制命令。
在该技术方案中, 可以在同一个遥控装置 10上实现对臂架或支腿 4的 控制, 实现了多个功能的集成, 可以在不改变现有装置的基础上, 实现多 功能的复用, 节省设计和开发成本。
如图 4所示, 在进行支腿控制时, 信号的传输过程如下:
用户通过遥控装置 10对工程机械上的支腿 4进行控制, 其中, 该遥控 装置 10与工程机械为无线连接。 遥控装置 10在用户控制下, 向工程机械 上设置的遥控接收器 20发送遥控信号, 进一步来讲, 这里的遥控信号可以 为红外信号、 蓝牙信号、 无线局域网络信号等。
遥控接收器 20将接收到的遥控信号转发至支腿控制器 2, 该遥控信号 中包含由支腿控制命令, 则支腿控制器 2将对该支腿控制命令进行分析, 判断出需要控制的对象及操作方式, 比如需要使左侧的两个支腿 4 同时进 行展开操作。
每个支腿通过电磁阀 3进行控制其动作, 而支腿控制器 2连接至所有 的电磁阀 3 , 当接收到遥控信号后, 生成对应的动作指令, 并发送至需要进 行控制的支腿 4对应的电磁阀 3。
进一步来讲, 这里的电磁阀 3可以为比例电磁阀, 则遥控装置 10发出 的遥控信号中可以包含有速度信号, 从而支腿控制器 2发出的动作指令中
也可以包含有对应的速度指令, 以通过调节所述比例电磁阀的阀芯的位移 量, 来控制阀门开度, 并最终实现对支腿 4的动作速度的控制。
综上所示, 本发明的技术方案中, 由于采用无线遥控的方式, 使得支 腿在进行动作时, 不会打到操作人员, 提升了操作的安全性; 同时, 通过 对多个支腿的同步控制, 可以提高工作效率, 并且避免了由于单个支腿支 撑而导致工程机械失去平衡, 甚至发生倾翻事故。
以上所述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。
