The horizontal slide rail 31 is divided into transverse concave groove, the upper wall of the transverse concave groove with 32 slide contact part of outer mast
With equidistant pressure sensor is installed on lower wall, the pressure sensor of upper wall and lower wall corresponding position is in horizontal position
Projection is overlapped (i.e. the pressure sensor of corresponding position is located on same vertical line).
In this way, when outer mast 32 passes through, the pressure sensor can generate corresponding pressure, so that it is determined that outer mast 32
The distance of insertion.
Multiple idler wheels are provided on outer mast 32, the outer mast 32 passes through the idler wheel in the cross of the horizontal slide rail 31
It is slided into groove.
Multiple pressure sensors are connect with a controller, and the controller reads the pressure data of pressure sensor, and counts
Calculate the distance that outer mast 32 enters horizontal slide rail 31.
Outer mast 32 enters the calculation formula of the distance D of horizontal slide rail 31 are as follows:
In formula, MiIt is determined 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 intermediate pressure
The serial number of sensor, x1iFor i-th of pressure sensor of upper wall, x2iFor i-th of pressure sensor of lower wall, d is equidistantly to set
The distance between pressure sensor set, d1For the 1st distance of the pressure sensor apart from 31 top of horizontal slide rail, d2For external door
1st idler wheel distance apart from outer mast 32 top of 32 top of frame to centre, MiFor the corresponding judgement of i-th of pressure sensor
Value.
Under normal circumstances, if measured by the distance that pressure sensor enters horizontal slide rail 31 to outer mast 32
Words, not only need the data to each pressure sensor to count, it is also necessary to be compared two-by-two to data, such one
Come, there are many time of consuming and resource；In addition, outer mast 32 is when sliding into horizontal slide rail 31, and in rigid slide into, outer mast
32 top is resisted against the upper wall of 31 transverse concave groove of horizontal slide rail, and after sliding into a distance, 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 are indefinite, are difficult
Determine the top of outer mast 32 can be resisted against which part of the transverse concave groove, this just brings to range measurement work very big
Puzzlement.
Its concrete thought are as follows: by the pressure sensor and the adjacent difference for needing pressure sensor of same serial number divided by difference
Difference is converted positive value and negative value by the absolute value of value；Again by will be on the occasion of being converted into judgment value, if at this time divided by two after adding one
The pressure value of the pressure sensor of same serial number is higher than the sum of adjacent pressure value, then its judgment value is 1, if the pressure of same serial number
The pressure value of sensor is lower than the sum of adjacent pressure value, then its judgment value is 0；Then using the judgment value as the pressure of corresponding serial number
Force snesor is to the factor of 31 top distance of horizontal slide rail, to eliminate the pressure sensor that judgment value is 0, (i.e. idler wheel is not at this
Pressure sensor at position) corresponding distance, obtain each idler wheel to 31 top of horizontal slide rail distance；In remaining distance
It is middle selection it is maximum that, for outer mast 32 enter horizontal slide rail 31 distance.
It has the beneficial effect that by the way that the upper wall at same position to be added with the pressure value of the pressure sensor of lower wall, eliminates
Idler wheel does not know the problem of bringing to measurement against upper wall or lower wall；By by the pressure sensor and adjacent bit at same position
The pressure of the pressure sensor at the place of setting is handled, to eliminate individual pressure sensors failure or external interference bring error number
According to；By the way that the pressure difference value of the pressure sensor of pressure sensor and adjacent position at same position is converted to judgement
Value, to eliminate the pressure sensor of idler wheel not at this location, obtains rapidly judging result, not only by way of calculating in this way
Avoid it is many and diverse compare one by one, improve judgement speed, and simple, it is convenient；By being selected in the distance of each idler wheel
The distance for entering horizontal slide rail 31 after that maximum processing as outer mast 32, can eliminate the mechanical problem of pressure sensor
Caused by error.In this way, actual range can be directly obtained by calculation formula, and it is simple and convenient, it calculates quickly, and occupy system
Resource is few.
