Problems solved by technology

However, in the development process of the overall controller, the cost of real vehicle testing is very high
Moreover, because the central controller of the first test will have many defects such as software and hardware, if the central controller is directly assembled in the construction machinery equipment, it will not be convenient for the initial debugging of the central controller on the one hand, and on the other hand, the control Serious defects of the device will also lead to damage to construction machinery and equipment or safety accidents, resulting in unnecessary losses
Therefore, under normal circumstances, it is not suitable to directly install the central controller in the construction machinery equipment

Embodiment Construction

[0022] Please also refer to figure 1 and figure 2 The power matching control simulation test system of the truck crane of the present invention includes simulation equipment, simulation monitoring computer, central controller and monitoring equipment.

[0023] The simulation device simulates the powertrain of the truck crane and produces output information. The power transmission system of the truck crane includes the engine, the metering pump, the main control valve, the hydraulic cylinder and the hydraulic motor. The engine drives the quantitative pump to output hydraulic oil, and the hydraulic oil reaches the hydraulic cylinder or hydraulic motor through the main control valve to drive the load.

[0024] The simulation equipment specifically includes the power transmission model of the truck crane, a real-time processor, an analog IO (Input-Output, input-output) module, a digital IO module, a high-frequency signal module, a communication module and a signal conditioning ...

Abstract

The invention discloses a power matching controlling simulation testing system of an automobile crane. The power matching controlling simulation testing system of the automobile crane comprises simulated equipment, a central control unit and monitoring equipment. The simulated equipment is used for simulating a power transmission system of the automobile crane and output information is produced. The central control unit is used for obtaining the output information. A matching revolving speed of a motor is calculated by the output information, thus the revolving speed of the motor of the simulated equipment is adjusted to the matching revolving speed. The output information and the matching revolving speed are displayed and a parameter and an algorithm of the central control unit are modified through the monitoring equipment. The power matching controlling simulation testing system of the automobile crane has the advantages of being saving in cost, convenient to adjust and the like.

Description

technical field [0001] The invention relates to construction machinery equipment, in particular to a power matching control simulation test system of a truck crane. Background technique [0002] With the increasing awareness of global environmental protection and the decreasing oil resources, the major manufacturers of construction machinery and equipment all over the world regard electronic energy saving and control technology as the main direction of the development of construction machinery technology. [0003] The central controller used in construction machinery and equipment is relatively complex, so that the central controller needs to be repeatedly debugged in the development to finally achieve the expected control function. However, in the development process of the overall controller, the real vehicle test cost is very high. Moreover, because the central controller of the first test will have many defects such as software and hardware, if the central controller is...
