In formula, MiDetermined by following formula：
In formula, D is the distance that outer mast 32 enters horizontal slide rail 31, and i is from 31 top of horizontal slide rail to middle pressure
The sequence number of sensor, x1iFor i-th pressure transducer of upper wall, x2iFor i-th pressure transducer of lower wall, d is equidistantly to set
The distance between pressure transducer put, d1For the 1st pressure transducer apart from 31 top of horizontal slide rail distance, d2For external door
Distance of 1st roller on 32 top of frame to centre apart from 32 top of outer mast, MiFor the corresponding judgement of i-th pressure transducer
Value.
Generally, if measured into the distance of horizontal slide rail 31 to outer mast 32 by pressure transducer
Words, not only need to count the data of each pressure transducer, in addition it is also necessary to contrast data two-by-two, such one
Come, the time of consuming and resource are a lot；In addition, outer mast 32 is when horizontal slide rail 31 are slipped into, and when just slipping into, outer mast
32 top is resisted against the upper wall of 31 transverse concave groove of horizontal slide rail, and after a segment distance is slipped into, the top of outer mast 32 is resisted against
The lower wall of 31 transverse concave groove of horizontal slide rail, so, the upper wall and lower wall stress of 31 transverse concave groove of horizontal slide rail is indefinite, it is difficult to
Determine the top of outer mast 32 can be resisted against which part of the transverse concave groove, this just brings very big to range measurement work
Puzzlement.
Its concrete thought is：By the pressure transducer of same sequence number with the adjacent difference for needing pressure transducer divided by difference
The absolute value of value, by difference be converted on the occasion of and negative value；Again by Jia one after will be on the occasion of judgment value be converted into, if now divided by two
The pressure value of the pressure transducer of same sequence number is higher than adjacent pressure value sum, then its judgment value is 1, if the pressure of same sequence number
The pressure value of sensor is less than adjacent pressure value sum, then its judgment value is 0；Then using the judgment value as the pressure for corresponding to sequence number
The factor of the force transducer to 31 top distance of horizontal slide rail, so as to eliminate the pressure transducer that judgment value is 0, (i.e. roller is not at this
Pressure transducer at position) corresponding distance, each roller is obtained to the distance on 31 top of horizontal slide rail；In remaining distance
Middle to select that maximum, which is the distance that outer mast 32 enters horizontal slide rail 31.
Have the beneficial effect that：By the upper wall at same position is added with the pressure value of the pressure transducer of lower wall, eliminate
The problem that roller does not know to bring to measurement against upper wall or lower wall；By by the pressure transducer and adjacent bit at same position
The pressure of the pressure transducer at the place of putting is processed, and eliminates the error number that individual pressure sensors failure or external interference are brought
According to；Judgement is converted to by the pressure difference value by the pressure transducer at same position with the pressure transducer of adjacent position
Value, eliminates pressure transducer of the roller not at the position, so draws rapidly judged result by way of calculating, not only
Avoid it is numerous and diverse compare one by one, improve judgement speed, and simply, it is convenient；By selecting in the distance of each roller
The distance of horizontal slide rail 31 is entered after that maximum process as outer mast 32, the mechanical problem of pressure transducer can be eliminated
The error for causing.As such, it is possible to actual range is directly obtained by computing formula, and it is simple and convenient, calculate quick, and take system
Resource is few.
