The invention relates to the field of engineering machinery, in particular to a locking control method, device and system for a crane and the crane, and the locking control method comprises the following steps: judging whether the crane is in a state needing to be locked or not; when the crane needs to be locked, whether the crane is running or not is judged, if the crane is in a non-running state, a locking instruction is sent to the engine, and engine starting is limited to achieve locking; the method for judging whether the crane needs to be locked or not comprises the steps that the service life of the crane and a random dynamic password generated by a control unit are obtained; acquiring a machine locking password generated according to the random dynamic password and the service life; and the control unit verifies the locking password and judges whether the crane is in a state needing to be locked or not according to the service life. By means of the method, remote machine locking and unlocking can be rapidly achieved.
本发明涉及工程机械领域,尤其涉及一种起重机用锁机控制方法、装置系统和起重机,所述锁机控制方法包括以下步骤:判断起重机是否处于需要锁机的状态;当起重机需要锁机时,判断起重机是否正在运转,如果起重机处于非运转状态,向发动机发送锁机指令,限制发动机启动实现锁机;判断起重机是否处于需要锁机的状态的方法包括:获取起重机使用期限,以及控制单元生成的随机动态密码;获取根据随机动态密码和使用期限生成的锁机密码;控制单元对锁机密码进行验证,并根据使用期限判断起重机是否处于需要锁机的状态。本发明所述方法可快速实现远程锁机及解锁。
