Embodiment

As shown in Figure 1, system is made up of analog machine functional unit, sensor, single-chip microcomputer, Programmable Logic Controller (being made up of mainboard, mainboard electrical equipment processing unit, storage unit) and display.After the action of operator's console is collected signal by sensor, pass to single-chip microcomputer through the signal data line, by usb data line input Programmable Logic Controller, Programmable Logic Controller is presented at operational motion on the screen by display through after the signal Processing after the single-chip microcomputer deal with data.

As shown in Figure 2, operator's console comprises worktable 18, be installed in swing arm/lifting fork operating grip 10, scraper bowl/door frame operating grip 9 on the worktable 18, bearing circle 16 and connecting rod 17, shift handle 15, parking brake 14, clutch 13, brake 12, throttle 11, sensor-based system 6 is installed in its underpart, each sensor 6 is transferred to one stage signal processing single chip 4 by data line 5, pass to second signal by USB interface 3 after signal is handled through single-chip microcomputer 4 and handle Programmable Logic Controller 2, handle the back through Programmable Logic Controller and pass to display 1 demonstration by the VGA19 data line.

System software comprises shovel loader, fork truck two systems of cover simulation function software, carries out the operation and the study of selective loading machine and forklift simulation problem by button.

The operation system of software of this simulator comprises simulated operation chamber interior and two kinds of operations of simulated operation outdoor field-of-view mode.

Single-chip microcomputer 4 also can be connected with Programmable Logic Controller 2 by other data-interface.

System also can not use Programmable Logic Controller 2, by realize the function of Programmable Logic Controller 2 on single-chip microcomputer 4.

After opening the simulator main power switch, start Programmable Logic Controller and graphic display system, the motion picture when making the shovel loader of gathering arrangement or fork truck work is presented on the screen synchronously.

When simulator bearing circle 16 clockwise, rotate counterclockwise, the angle that the sensor-based system 6 below the bearing circle rotates according to the simulator bearing circle, at this moment sensor-based system 6 can produce different resistance, passes to single-chip microcomputer 4 thereby have corresponding electric current by data line 5.After single-chip microcomputer 4 carries out the one-level processing with signal, pass to Programmable Logic Controller 2 again by USB connecting line 3, shovel loader, forklift operator simulation softward are housed in the Programmable Logic Controller 2, the one stage signal that the direction that the operation simulation program passes over according to single-chip microcomputer 4 is rotated is carried out virtual rotation, and pass to display system 1 by VGA data line 19, and in display system 1, show, displayed content is consistent with simulation bearing circle rotational angle.

When pin was stepped on clutch coupling 13, the sensors 6 below clutch coupling 13 passed to 4 one signals of single-chip microcomputer and cut off the actuating signal that running gear control lever and respective sensor 6 pass over.After shift operating grip 15 is finished the shift action, loosen the clutch 13 shutoff signals are removed, the primary signal that single-chip microcomputer 4 will pass over according to new gear passes to Programmable Logic Controller 2 again and handles, thereby display 1 shows corresponding different working modes, reaches truly purpose intuitively.

In simulated operating procedure, load and other actions when needing brake when running into, step on brake 12 at this moment corresponding sensor-based systems 6 and can transmit signal to single-chip microcomputer 4, single-chip microcomputer 4 can be made the signal that cuts off walking, stops through Programmable Logic Controller 2 processing back display devices on display 1 equally and carries out other actions.

After the simulation system simulated engine was flame-out, system sent the shutting engine down simulated sound, and at this moment we pull down parking brake 14 according to safety instruction and pass to single-chip microcomputer 4 by corresponding sensor 6, and single-chip microcomputer 4 is finished the everything signal by operation.

When needs carrying fork/when lifting big arm, manipulation bar 10 upwards, the action of operating rod 10 is converted to electronic signal by sensor-based system 6 and passes to single-chip microcomputer 4 and carry out signal Processing, passes to Programmable Logic Controller by the usb data line and carries out showing synchronously on display system after the Image Information Processing.As accelerating carrying fork/lift big arm speed, depress throttle 11, its speed can be according to the variation on the size generation speed of throttle 11.

When fall to pitching/when falling big arm, manipulation bar 10 is downward, the action of operating rod 10 is converted to electronic signal by sensor 6 and passes to single-chip microcomputer 4 and carry out signal Processing, passes to Programmable Logic Controller by the usb data line and carries out picture information and handle the back and show synchronously on display system.As the fork of will accelerating to fall/fall the speed of big arm, only need operating rod 10 downward strokes are strengthened, its speed can be according to the variation on the stroke size generation speed.

Other move handles as mentioned above, and institute's respective operations action real simulation physical device operation duty is reproduced the authenticity of operation by the visual field directly perceived that display is broad.
