Emergency braking method for construction machinery
The invention relates to an emergency braking method for engineering machinery, the engineering machinery comprises a generator, at least one motor and a main controller, the generator, the motor and the main controller are connected in series on a current loop, and the main controller is configured to receive an operation instruction from a user and provide corresponding excitation current for the generator based on the operation instruction. The current loop is configured to generate armature current on the engineering machinery, the motor is configured to drive the engineering machinery to execute corresponding operation on the basis of the armature current generated by the generator, and the method comprises the following steps: judging whether an emergency braking request is received or not on the basis of an operation instruction from a user; and upon receiving an emergency braking request, applying a reverse excitation current opposite to the current excitation current to the generator to force the at least one electric motor to decelerate.
本发明涉及一种用于工程机械的紧急制动方法，所述工程机械包括串联连接在电流回路上的发电机、至少一个电动机以及主控制器，所述主控制器配置为接收来自用户的操作指令并基于该操作指令向所述发电机提供相应的励磁电流，以激励所述发电机在所述电流回路上产生电枢电流，所述至少一个电动机配置为基于由所述发电机产生的电枢电流驱动所述工程机械执行相应的操作，其中，该方法包括如下步骤：基于来自用户的操作指令判断是否接收到紧急制动请求；和在接收到紧急制动请求的情况下，向所述发电机施加与当前励磁电流方向相反的反向励磁电流，以迫使所述至少一个电动机减速。
