Further, described unload put region, scoop up region, transit domain distinguishes display with gradient color mode or line segment partitioning scheme in display plane, described optimal region, rationally region, hazardous location distinguish display with gradient color mode or line segment partitioning scheme in display plane.
Further, described graphics mode can be any planar graphs such as circle, rectangle, star, triangle, for representing the corresponding point in system of axes of the coordinate of luffing angle and roll angle composition intuitively, i.e. pallet fork attitude and residing attitude region thereof.
As another technical scheme, the present invention also provides a kind of forklift truck pallet fork display device for gestures, and for realizing display according to above-mentioned display method provided by the invention, described read out instrument comprises:
Data input pin, for introducing luffing angle data and the roll angle data of pallet fork;
Display module, puts region for unloading with gradient color mode or the display of line segment partitioning scheme, scoops up region, transit domain and optimal region, rationally region, hazardous location, and demonstrates pallet fork attitude and residing attitude region thereof in planar graph mode;
Alarm unit, reports to the police for one or more the combination of uploading in form with sound, light, word, icon, network when pallet fork attitude is in hazardous location.
Compared to prior art, described forklift truck pallet fork attitude display method of the present invention and read out instrument demonstrate pallet fork attitude and residing attitude region thereof in planar graph mode, thus carry out loading and unloading auxiliary and operation guide in real time, realize security alarm, improve operating efficiency and safety.

Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
Fig. 1 is the schematic diagram of the forklift truck pallet fork attitude display method according to the embodiment of the present invention, and as shown in Figure 1, this forklift truck pallet fork attitude display method comprises:
In the display plane of read out instrument, define orthogonal luffing angle coordinate axle Y and roll angle coordinate axle X, form plane right-angle coordinate; According to being applicable to discharging, shovel material, pallet fork luffing angle variation range that haul three kinds of working conditions are corresponding respectively, in the Y-axis direction, by pallet fork luffing angle
regional planning for unload put region,
regional planning for scoop up region,
regional planning be transit domain; According to there is the hazard level corresponding pallet fork roll angle scope of tumbling under each working condition, in the X-axis direction, by pallet fork roll angle
regional planning be optimal region,
with
regional planning be reasonable region,
with
regional planning be hazardous location; Read out instrument obtains the luffing angle of pallet fork
and roll angle
composition coordinate
, in system of axes, show the point that this coordinate is corresponding to graphically, such as, in Fig. 1 A point.
Further, described unload put region, scoop up region, transit domain distinguishes display with gradient color mode or line segment partitioning scheme in display plane, described optimal region, rationally region, hazardous location distinguish display with gradient color mode or line segment partitioning scheme in display plane, such as respectively described in Fig. 1 interregionally to split with line segment.
