Problems solved by technology

[0004] However, the above-mentioned speed regulation method can only adjust the gear speed, that is, fast and slow, and cannot continuously adjust the speed. The application scenarios are limited and it is difficult to meet all needs; at the same time, there will be very large shaking during the switching process , affecting the construction and operation of operators

Embodiment

[0028] Example: Reference Figure 1-4 , a flexible control system for the movement of a mobile lifting platform, including a rotary switch, a platform IO module, a main controller, and an engine ECU.

[0029] Rotary switch: used to convert mechanical rotational displacement into an output signal of current change. During operation, the staff manually drives the knob switch according to actual needs. The output current signal of the rotary switch gradually increases from the initial position to the end position.

[0030] Platform IO module: used to obtain and judge the output signal of the rotary switch and generate communication signals; the platform IO module judges the position of the rotary switch according to the output signal of the rotary switch, and transmits the position information of the rotary switch to the main controller.

[0031] Main controller: used to respond to the communication signal of the platform IO module and generate an output signal; different posit...

Embodiment 2

[0041] Embodiment 2, refer to figure 1, a mobile lifting platform action flexible control system, compared with embodiment 1, increases the human-computer interaction interface, the human-computer interaction interface is connected with the main controller through the data line, and can display the working status of all solenoid valves and engines At the same time, the human-computer interaction interface can also be manually edited, so that the main controller can generate output signals for controlling the engine ECU and the action execution valve group after responding to the instructions of the human-computer interaction interface. The human-computer interface can control the I of each solenoid valve or engine throttle min , I max , N min , N max Make numerical edits. The human-computer interaction interface is specifically a display screen.

[0042] The implementation principle of the above-mentioned embodiment is as follows: the current value of the knob switch is u...

Abstract

The invention relates to a flexible control system for the movement of a mobile lifting platform, which is applied in the technical field of flexible control of hydraulic circuits. And judge the output signal of the knob switch and generate a communication signal; the main controller: used to respond to the communication signal of the platform IO module and generate an output signal; engine ECU: used to generate and control the engine throttle with the output signal of the main controller as the input signal The output signal of the action execution valve group: it is used to generate the output signal to control the size of the valve with the output signal of the main controller as the input signal. The present invention has the advantages of realizing stepless and continuous speed change of all actions, thereby better adapting to different working environments and improving the safety of the work.

Description

technical field [0001] The invention relates to the technical field of flexible control of hydraulic circuits, and more specifically, it relates to a flexible control system for the movement of a mobile lifting platform. Background technique [0002] The mobile lifting platform can walk quickly and slowly under different working conditions, and can continuously complete up and down, forward, backward, and turn signal work on the convenient operation platform in the air. There are many types of classification, among which the straight crank arm lifting platform has a large operating range and a wide range of operating heights. [0003] When the working platform is ready-made, the speed needs to be adjusted according to the demand, for example, it needs to reach the vicinity of the construction site quickly, and slowly adjust to the best position. The execution of the action depends on the hydraulic cylinder controlled by the engine or the action execution valve. The existing...
