With equally spaced pressure transducer is installed on lower wall, the pressure transducer of upper wall and lower wall correspondence position is at horizontal level
Projection overlaps (i.e. the pressure transducer of correspondence position is positioned on same vertical curve).
So, at outer mast 32 through out-of-date, described pressure transducer can produce the pressure of correspondence, so that it is determined that outer mast 32
The distance inserted.
Being provided with multiple roller on outer mast 32, described outer mast 32 passes through the described roller horizontal stroke at described horizontal slide rail 31
Slide in groove.
Multiple pressure transducers and a controller connect, and described controller reads the pressure data of pressure transducer, and counts
Calculate outer mast 32 and enter the distance of horizontal slide rail 31.
Outer mast 32 enters the computing formula of the distance of horizontal slide rail 31:
In formula, following formula determine:
In formula, enter the distance of horizontal slide rail 31 for outer mast 32, pass for the pressure from horizontal slide rail 31 top to centre
The sequence number of sensor, for the pressure transducer of upper wall, for the pressure transducer of lower wall, the pressure for spaced set passes
Distance between sensor, is the distance on the 1st pressure transducer distance horizontal slide rail 31 top, for outer mast 32 top to middle
The distance on the 1st roller distance outer mast 32 top, be the judgment value that the pressure transducer is corresponding.
Generally, if outer mast 32 being entered what the distance of horizontal slide rail 31 measured by pressure transducer
Words, not only need to add up the data of each pressure transducer, in addition it is also necessary to contrast data two-by-two, such one
Coming, time and the resource of consuming are a lot；It addition, outer mast 32 is slipping into horizontal slide rail 31 when, when just slipping into, outer mast
The top of 32 is resisted against the upper wall of horizontal slide rail 31 transverse concave groove, and after slipping into a segment distance, the top of outer mast 32 is resisted against
The lower wall of horizontal slide rail 31 transverse concave groove, so, upper wall and the lower wall stress of horizontal slide rail 31 transverse concave groove are indefinite, are difficult to
Determining the top of outer mast 32 can be resisted against which part of described transverse concave groove, this just brings the biggest to range measurement work
Puzzlement.
Its concrete thought is: need the difference of pressure transducer divided by difference by the pressure transducer of same sequence number with adjacent
Value absolute value, difference is converted on the occasion of and negative value；Again by will be on the occasion of being converted into judgment value divided by two after adding one, if now
The force value of the pressure transducer of same sequence number is higher than adjacent force value sum, then its judgment value is 1, if the pressure of same sequence number
The force value of sensor is less than adjacent force value sum, then its judgment value is 0；Then using this judgment value as the pressure of corresponding sequence number
Force transducer is to the factor of horizontal slide rail 31 top distance, thus (i.e. roller is not at this to eliminate the pressure transducer that judgment value is 0
The pressure transducer of position) corresponding distance, obtain each roller distance to horizontal slide rail 31 top；In remaining distance
Middle selecting maximum that, it is the distance that outer mast 32 enters horizontal slide rail 31.
Have the beneficial effect that by the force value of the pressure transducer of the upper wall at same position and lower wall is added, eliminate
Roller is against the uncertain problem brought to measurement of upper wall or lower wall；By by the pressure transducer at same position and adjacent bit
The pressure of the pressure transducer at the place of putting processes, and eliminates individual pressure sensors fault or error number that external interference is brought
According to；By the pressure difference value of the pressure transducer at same position Yu the pressure transducer of adjacent position being converted to judgement
Value, eliminates roller not at the pressure transducer of this position, so draws rapidly judged result, not only by the way of calculating
Numerous and diverse the comparing one by one avoided, improves judgement speed, and simply, facilitates；By selecting in the distance of each roller
Enter the distance of horizontal slide rail 31 after that maximum process as outer mast 32, the mechanical problem of pressure transducer can be eliminated
The error caused.As such, it is possible to directly obtain actual range by computing formula, simple and convenient, calculate quickly, and take system
Resource is few.
