Step：
Step 1 determines that step sizes, the step-length, that is, number tape are quick in conjunction with data characteristics and practical interpretation effect
Minimum step when rolling, the physics saltus step limit of data characteristics, that is, real data parameter, determines that step-length is big according to data characteristics
Range is caused, step sizes are determined come final according to practical interpretation effect.
Step 2, in interpretation a period data and currently practical data absolute value of the difference have been displayed, according to absolute value with
The relationship of step-length carries out following handle respectively：
If absolute value is less than or equal to step-length, this period shows real data；
If absolute value is more than step-length, following place was done with currently practical data difference according to the data that have been displayed in a upper period
Reason：If the data that have been displayed in a upper period are less than currently practical data, the data value of this period display is that real data adds step
It is long；If the data that have been displayed in a upper period are more than currently practical data, the data value of this period display is that real data subtracts step
It is long.
The beneficial effects of the invention are as follows：The present invention is shown by the idler wheel characteristic of analog mechanical instrument to rolling number tape
The mode of showing is improved, and data smoothing Processing Algorithm is added, and when data source fluctuation is larger, number tape is rolled in a manner of idler wheel always
Actual numerical value is moved, more intuitive and accurate display data eliminates interpretation influence, and the vision for alleviating pilot significantly is tired
Labor.
Description of the drawings
Fig. 1 is logic chart of the present invention for the simulation idler wheel display methods of airbome liquid crystal display.
Specific implementation mode
The following further describes the specific embodiments of the present invention with reference to the drawings.
Referring to Fig. 1, a kind of simulation idler wheel display methods for airbome liquid crystal display of the invention includes the following steps：
Step 1 determines step sizes according to data characteristics, the minimum step when step-length, that is, number tape fast scroll,
The physics saltus step limit of data characteristics, that is, real data parameter.
Step 2, in interpretation a period data and currently practical data absolute value of the difference have been displayed, according to absolute value with
The relationship of step-length carries out following handle respectively：
If absolute value is less than or equal to step-length, this period shows real data；
If absolute value is more than step-length, following place was done with currently practical data difference according to the data that have been displayed in a upper period
Reason：If the data that have been displayed in a upper period are less than currently practical data, the data value of this period display is that real data adds step
It is long；If the data that have been displayed in a upper period are more than currently practical data, the data value of this period display is that real data subtracts step
It is long.
Step 3 inputs saltus step data to data application simulation idler wheel display methods, when observing number tape fast scroll
Interpretation effect carries out plus-minus amendment to step-length, executes step 2 and step 3 repeatedly, can be rolled with prestissimo with number tape but
It is optimal display result not influence interpretation again, finally determines step sizes.
In the idler wheel of the picture stimulated display machinery instrument of liquid crystal display, and use data processing algorithm simulation idler wheel
Characteristic.Specific implementation is that data smoothing Processing Algorithm (see Fig. 1), the calculation are added on the basis of existing rolling number tape is shown
Data and the size of data to be displayed have been displayed in method by comparing, to control and export actual display data, export every time
Actual value increase and decrease amount does not exceed the step-length of setting, to achieve the effect that number tape smooth rolling.
The minimum step when step-length of the algorithm, i.e. number tape fast scroll comes in combination with data characteristics and practical interpretation
Determine step sizes.
The algorithm has certain lag to show real time data, is added in showing picture cycle refresh function, with existing
The physics saltus step limit of the periodic refresh time≤40ms and real data parameter that show picture calculate, which will not
Influence the operational motion of operating personnel.
When data initialization or yard and meter turn, which can be number to be shown by actual displayed data indirect assignment
According to eliminate the data jump influence that data initialization or yard and meter turn are brought.
When the fluctuation of airbome liquid crystal display picture data source is larger, number carries the effect of smooth rolling, always with rolling
Wheel mode is rolled to actual numerical value, and more intuitive and accurate display data, eliminating interpretation influences.Present invention can apply to airborne
The graphic display picture of liquid crystal display, the graphical display algorithm (such as air speed, height etc.) of certain data digital readers.
Embodiment：
To the digital readout application simulation idler wheel display methods of flying height：
Step 1：Determine step sizes.When object does the movement of falling object on earth, the shadow of acceleration of gravity is considered
It rings, speed is increasing, and when final gravity and frictional force reach balance, object moves with uniform velocity, and considers this limit velocity, greatly
Cause takes 200m/s, i.e. one second 200 meters of height change (aircraft practical flight altitude information can not possibly reach this limiting value), selects picture
Face refreshing frequency is 40ms, i.e., averagely each cycle data variation is 8 meters.
Step 2：In interpretation a period have been displayed height and currently practical height absolute value of the difference, according to absolute value and 8
The size of rice carries out following handle respectively：
If absolute value is less than or equal to 8 meters, this period shows real data；
If absolute value is more than 8 meters, following processing was done with currently practical data difference according to the data that have been displayed in a upper period：
If the data that have been displayed in a upper period are less than currently practical data, the data value of this period display is that real data adds 8 meters；If
The data that have been displayed in a upper period are more than currently practical data, then the data value of this period display is that real data subtracts 8 meter.
Step 3：To altitude information application simulation idler wheel display methods, 0 to 1000 meters of saltus step data, number tape rolling are inputted
Interpretation can be understood when dynamic, but number tape rolling speed is partially slow, is modified to step-length, be revised as 10 meters on the basis of 8 meters, hold
After row step 2 and step 3, number tape rolling speed is accelerated, and can understand interpretation, is modified to step-length, on 10 meters of basis
On be revised as 11 meters, after executing step 2 and step 3, number tape rolling speed is accelerated, but data interpretation is unclear.Repeatedly really
It is final to determine that step sizes are 10 meters after recognizing.
