Referring to fig. 1, fig. 1 is a schematic diagram of a system of an electrically driven aerial work vehicle control system 10 according to an embodiment of the present disclosure. In the embodiment of the application, the control system 10 of the electrically-driven overhead working truck can improve the operation coordination of each component structure of the electrically-driven overhead working truck during operation, reduce the hard collision and impact of the moving machine body, prolong the service life of the overhead working truck, and improve the operation comfort and safety guarantee coefficient of operators. The electrically-driven overhead working truck generally comprises a boom structure, a rotary table structure, a working platform and a bearing truck body, wherein the rotary table structure is arranged on the bearing truck body, the boom structure is arranged on the rotary table structure, and the working platform is arranged on the boom structure. The bearing vehicle body can drive the arm support structure, the rotary table structure and the operation platform to move, the arm support structure can be used for driving the operation platform to move to a specified operation height and/or a specified operation position, and the rotary table structure can be used for driving the rotary table structure and the operation platform to rotate.

In the present embodiment, the electrically-driven aerial lift truck control system 10 includes a main control unit 110, a platform control unit 120, a turntable control unit 130, and a travel control unit 140. The platform control unit 120 is configured to control an operating condition of the boom structure, so as to ensure that the operation platform can normally implement an operation task; the turntable control unit 130 is used for controlling the operation condition of the turntable structure; the running control unit 140 is used for controlling the running condition of the carrier vehicle body; the main control unit 110 is configured to control respective operations of the stage control unit 120, the turntable control unit 130, and the travel control unit 140.

In this embodiment, the main control unit 110 is electrically connected to the platform control unit 120, and is configured to respond to a target boom action input by an operator, generate an operation instruction corresponding to the target boom action, and send the operation instruction to the platform control unit 120, so that the platform control unit 120 controls the boom structure of the electrically-driven aerial work platform according to the operation instruction to drive the operation platform to move in an acceleration/deceleration manner smoothly until the boom structure completes the target boom action.

When the platform control unit 120 starts to control the boom structure to execute the target boom action, the boom structure may be controlled to drive the operation platform to move smoothly and at an accelerated speed, so that the boom structure may not be subjected to a large hard collision and impact before and after executing the target boom action, and when the boom structure is about to complete the target boom action, the platform control unit 120 may also control the boom structure to drive the operation platform to move smoothly and at a decelerated speed, so that the boom structure may not be subjected to a large hard collision and impact when completing the target boom action.

Optionally, referring to fig. 2, fig. 2 is one of the schematic component diagrams of the platform control unit 120 in fig. 1. In this embodiment, the platform control unit 120 may include a platform controller 121, a platform proportional valve 122, and a plurality of operation direction switch valves 123, where the boom structure is formed by connecting a plurality of operation arms in series, and at least one operation direction switch valve 123 is disposed at a connection joint between two adjacent operation arms, where the operation direction switch valve 123 is used to adjust an operation direction of the boom structure, and the platform proportional valve 122 is used to adjust an operation amplitude of the boom structure.

The platform controller 121 is electrically connected to each of the operation direction switch valves 123, and is configured to control each of the operation direction switch valves 123 related to the target boom motion to be opened or closed.

The platform controller 121 is electrically connected to the platform proportional valve 122, and is configured to smoothly adjust the duty ratio of the platform proportional valve 122 according to the real-time current of the platform proportional valve 122 and the target output current corresponding to the target boom motion included in the operation instruction until the real-time current of the platform proportional valve 122 is consistent with the target output current.

When the boom structure needs to start executing the target boom action, the platform controller 121 controls each operation direction switch valve 123 related to the target boom action to open, and then smoothly increases the duty ratio of the platform proportional valve 122 according to the real-time current of the platform proportional valve 122 and the target output current included in the operation instruction, so that the boom structure gradually tends to the target boom action until the real-time current of the platform proportional valve 122 is consistent with the target output current.

When the boom structure and the target boom act in a consistent manner, the platform controller 121 also starts to smoothly decrease the duty ratio of the platform proportional valve 122 until the duty ratio is adjusted to a minimum value (here, the minimum value of the duty ratio usually causes the real-time current of the platform proportional valve 122 to be smaller than the minimum acting current of the platform proportional valve 122), and then controls each operation direction switch valve 123 related to the target boom act to close, so that the boom structure is maintained in the state of the target boom act.

The first timing duration corresponding to the first timer 124 may be set to be in a range of 50ms to 200ms, so as to play a role of buffering between the switching valve control operation and the proportional valve control operation.

In this embodiment, the main control unit 110 is electrically connected to the turntable control unit 130, and is configured to respond to a target turntable action input by an operator, generate a rotation instruction corresponding to the target turntable action, and send the rotation instruction to the turntable control unit 130, so that the turntable control unit 130 controls the turntable structure of the electrically-driven overhead working truck to smoothly rotate at an increased speed or a decreased speed according to the rotation instruction until the turntable structure completes the target turntable action.

When the turntable control unit 130 starts to control the turntable structure to execute the target turntable action, the turntable structure can be controlled to smoothly accelerate and rotate, so that the turntable structure is not subjected to large hard collision and impact before and after the target turntable action is executed, and when the turntable structure is about to complete the target turntable action, the turntable control unit 130 can also control the turntable structure to smoothly decelerate and rotate, so that the turntable structure is not subjected to large hard collision and impact when the target turntable action is completed.

The turntable controller 131 is electrically connected to each of the rotation direction switch valves 133, and is configured to control each of the rotation direction switch valves 133 related to the target turntable operation to be turned on or off.

The turntable controller 131 is electrically connected to the turntable proportional valve 132, and is configured to smoothly adjust the duty ratio of the turntable proportional valve 132 according to the real-time current of the turntable proportional valve 132 and the target output current included in the rotation instruction until the real-time current of the turntable proportional valve 132 is consistent with the target output current.

When the turntable structure needs to start to execute a target turntable action, the turntable controller 131 controls the rotation direction switch valve 133 related to the target turntable action to be opened, and then smoothly increases the duty ratio of the turntable proportional valve 132 according to the real-time current of the turntable proportional valve 132 and the target output current included in the rotation instruction, so that the turntable structure gradually tends to the target turntable action until the real-time current of the turntable proportional valve 132 is consistent with the target output current.

When the turntable structure is consistent with the target turntable motion, the turntable controller 131 also starts to smoothly decrease the duty ratio of the turntable proportional valve 132 until the duty ratio is adjusted to a minimum value (where the minimum value of the duty ratio usually causes the real-time current of the turntable proportional valve 132 to be smaller than the minimum motion current of the turntable proportional valve 132), and then controls the rotation direction switch valve 133 related to the target turntable motion to close, so that the turntable structure is maintained in the target turntable motion state.

The second timing duration corresponding to the second timer 134 may be set to be in a range of 50ms to 200ms, so as to play a role of buffering between the on-off valve control operation and the proportional valve control operation.
