Embodiment
With reference to the accompanying drawings and by embodiments of the invention, technical scheme of the present invention is described in detail.
As shown in Figure 3, the invention provides a kind of area measurement method of ultraviolet-visible pectrophotometer, comprise: S1, one or two boost lines perpendicular to the data source transverse axis are set, described boost line can and can be chosen definite position by cancellation by selected change position; S2, determine the abscissa value of described boost line, this abscissa value comprises the first abscissa value and the second abscissa value.When described boost line is a boost line, determine that by twice the first abscissa value and the second abscissa value can be determined in the position of boost line.When described boost line is two boost lines namely when the first boost line and the second boost line, can determine the first abscissa value and determine the second abscissa value by the second boost line by the first boost line; S3, the abscissa value assignment of described boost line is calculated the district to area and respectively as starting point parameter and terminating point parameter; S4, according to described starting point parameter and the described boost line of the terminating point calculation of parameter area in the zone that data source limits.
As shown in Figure 4, the invention provides a kind of area measuring device of ultraviolet-visible pectrophotometer, comprising: setting device 1, be used at least one boost line perpendicular to the data source transverse axis is set, described boost line can be by selected change position; Really be worth device 2, be used for determining the abscissa value of described boost line, this abscissa value comprises the first abscissa value and the second abscissa value; Valuator device 3 is used for that the abscissa value assignment of described boost line is calculated the district to area and respectively as starting point parameter and terminating point parameter; Area calculation element 4 is used for according to described starting point parameter and the described boost line of the terminating point calculation of parameter area in the zone that data source limits.
For ultra-violet and visible spectrophotometer, the main body of carrying out area measurement is host computer.Need to prove, this host computer can be common computing machine, it can be connected with frequency analyzer by common or special-purpose computer interface, to spectrum analyzer manage, data are processed and data analysis, wherein, common interface is for example the RS232 interface, and special purpose interface is for example the VISA interface, but the embodiment of the present invention is not restricted to this.Before method in carrying out the present invention, host computer obtains data source from data acquisition equipment, and data source is processed on the interface through being presented in data after conversion.Particularly, this computing machine is data source and the viewing area that is presented at data source for the data transformation that ultraviolet-visible pectrophotometer is collected.According to the data type of ultraviolet-visible pectrophotometer collection and user's selection, the data source longitudinal axis can be absorbance, transmitance or energy, and transverse axis can be wavelength or time.This embodiment will be take the spectral measurement of ultraviolet-visible pectrophotometer as example, is absorbance according to the longitudinal axis of data source, and transverse axis is that wavelength describes.
In step S1, boost line and data source that setting device 1 is set are under the same coordinate system, and perpendicular to the data source transverse axis.Boost line can move according to user's operation input apparatus such as mouse, keyboard when selected.Particularly, boost line is selected by user's operating mouse, is converted to removable state from the stationary state of initial position, then through pulling the variation that realizes its position, determines its position until the user cancels to choose when it is dragged to the target location.
In step S2, really be worth device 2 and according to the user, the boost line that pulls cancelled and chosen, determine this abscissa value corresponding to boost line position this moment.Need to have two values of starting point and ending point of curve in the spectroscopic data source due to the measurement of ultraviolet-visible spectrophotometer area, therefore, need to determine the first abscissa value and the second abscissa value with boost line, thereby satisfy the requirement of area measurement.
But because the otherness of the curve of spectrum on each data source and user's operation is random, when the boost line that is pulled is cancelled when choosing, its abscissa value is not probably the abscissa value of point corresponding on data source.Therefore, further, really also comprise judgment means in value device 2, the following substep that is used for execution in step S2: judge whether described boost line forms the point of crossing with data source, if formed abscissa value that this point of crossing is corresponding as the abscissa value of described boost line, if do not form with on data source apart from the nearest corresponding abscissa value of point of this boost line as the abscissa value of described boost line and described boost line is moved to this nearest point.By above-mentioned steps, the present invention has had the user and the target location has been set the function that can automatically revise when makeing mistakes, and having overcome does not have the defective of respective handling measure in this case in the prior art.
And this step both can only be revised the abscissa value of the boost line that is pulled, and also can correspondingly upgrade the abscissa value of another boost line.
Particularly, setting device 1 arranges two boost lines i.e. the first boost line and the second boost line, and the abscissa value that is provided with two boost line initial positions lays respectively at 1/3rd places and 2/3rds places of transverse axis coordinate in whole viewing area coordinate system for example.Point on data source is what disperse, this 1/3rd place and 2/3rds places might not be the abscissa value of the point on data source so, in this case, above-mentioned substep according to judgment means, when pulling wherein a boost line and determining its abscissa value, the initial position of a mobile other boost line is about to that this other boost line moves to point nearest on data source and with the abscissa value of this point correspondence abscissa value as initial position.Take on transverse axis as example as the time, when the scope of this data source is 0 to 12 second, initial position is separately positioned on the first boost line and the second boost line 4 seconds and located in 8 seconds, if the sampling interval of this data source is 3 seconds, the horizontal ordinate that is the point of data source is respectively 0,3,6,9,12 second, and the first boost line and the second boost line initial position separately was not the abscissa value of the point on data source in 4 seconds and 8 seconds.Be the position of 5 seconds when the user pulls the first boost line and drags it to abscissa value, judgment means is judged, the first boost line horizontal ordinate be 5 seconds the position not and data source form the point of crossing, therefore the first boost line is revised, it is modified on data source abscissa value from its nearest point, namely made into 6 seconds, namely the first boost line can stop to locate by 6 seconds.Because the abscissa value of the initial position of the second boost line 2 is 8 seconds, the abscissa value of the point on neither data source, so judgment means is also revised it, the second boost line is moved and will stop on the data source from its nearest point, namely abscissa value is the position of 9 seconds.
In step S3, valuator device 3 calculates district according to starting point parameter and terminating point parameter and assignment to area with the abscissa value of boost line.Starting point parameter due to area in calculating should be less than terminating point parameter, so should compare the size of the first and second abscissa value with the first abscissa value of boost line and the second abscissa value and starting point parameter and terminating point parameter matching the time.Further, valuator device 3 comprises comparison means, the following substep that is used for execution in step S3: the size between more described the first abscissa value and described the second abscissa value, abscissa value less in is both calculated the starting point parameter in district as area, larger abscissa value is calculated the terminating point parameter in district as area.Could after the user utilizes boost line to limit the zone of measuring area, can rationally calculate like this.
Embodiment one
At least one boost line that in the present invention, setting device 1 arranges is two boost lines, is respectively the first boost line 100 and the second boost line 200, and, the first corresponding the first abscissa value of boost line 100; The second corresponding the second abscissa value of boost line 200.The user moves to after can choosing respectively regardless of order ground the first boost line 100 or the second boost line 200 to cancel behind target location separately and chooses when setting the surface area that will measure, thereby has determined the start-stop border of the segment of curve that intercepts.
For example shown in Figure 5, demonstrate the curve of this measurement in data source viewing area on the right.In step S1, create the first boost line 100 and the second boost line 200 according to the present embodiment, it is the first horizontal ordinate of initial position and 1/3rd places and 2/3rds places that the second abscissa value is respectively transverse axis coordinate in the coordinate system of whole viewing area separately, wavelength value corresponding to the first abscissa value of initial position is 500 nanometers, and wavelength value corresponding to the second abscissa value of initial position is 600 nanometers.The user chooses the first boost line 100 by clicking the mouse, pull the first boost line 100 and cancel and choose by discharging mouse behind the target location.
After the user discharges mouse, judgment means judges whether the first boost line 100 forms the point of crossing with data source, if formed abscissa value that this point of crossing is corresponding as the first abscissa value, if do not form will the nearest corresponding abscissa value of point of distance the first boost line 100 move to this nearest point as the first abscissa value and with the first boost line 100 on data source.At this moment, because the initial position of the second boost line 200 can form the point of crossing with data source, so the second boost line 200 is to keep motionless in the process that pulls the first boost line 100.
Then discharge mouse after another target location is chosen and be dragged to the second boost line 200, judgment means judges whether the second corresponding horizontal ordinate of boost line 200 forms the point of crossing with data source, if formed abscissa value that this point of crossing is corresponding as the second abscissa value, if do not form will the nearest corresponding abscissa value of point of distance the first boost line 200 move to this nearest point as the second abscissa value and with the second boost line 200 on data source.Certainly the user also can first choose and pulls the second boost line 200 and determine the second abscissa value, then chooses and pull the first boost line 100 and determine the first abscissa value.
The first situation, as Fig. 6, the user moves to the first boost line 100 target location that corresponding abscissa value is 550 nanometers, and the second boost line 200 is moved to the target location that corresponding abscissa value is 600 nanometers.Through the respectively judgement of judgment means to the first boost line 100, the second boost line 200, the first boost line 100 and the second boost line 200 have the point of crossing with at that time data source respectively, therefore do not need further boost line and its abscissa value to be revised, determine that directly the first abscissa value is 550 nanometers, the second abscissa value is 600 nanometers.The first abscissa value after comparison means will be determined and the size of the second abscissa value compare, by shown in Figure 6, the first abscissa value 550 nanometers are less than the second abscissa value 600 nanometers, therefore when the first abscissa value and the second abscissa value assignment being calculated the district and are the form on Fig. 6 left side to area, with the first abscissa value as the starting point parameter, and show in the beginning cell of being expert at of the cursor in the form on Fig. 6 left side, the second abscissa value as the terminating point parameter, and is shown in the end unit lattice of correspondence.
The second situation, by shown in Figure 7, the user moves to the first boost line 100 target location that corresponding abscissa value is 650 nanometers, and the second boost line 200 is moved to the target location that corresponding abscissa value is 600 nanometers.Through judgement respectively, the first boost line 100 and the second boost line 200 have the point of crossing with at that time data source respectively, determine that directly the first abscissa value is 650 nanometers, and the second abscissa value is 600 nanometers.The first abscissa value after comparison means will be determined and the size of the second abscissa value compare, by shown in Figure 6, the first abscissa value 650 nanometers are greater than the second abscissa value 600 nanometers, therefore when the first abscissa value and the second abscissa value assignment being calculated the district and are the form on Fig. 7 left side to area, with the second abscissa value as the starting point parameter, and show in the beginning cell of being expert at of the cursor in the form on Fig. 7 left side, the first abscissa value as the terminating point parameter, and is shown in the end unit lattice of correspondence.
Starting point parameter in cell and the terminating point calculation of parameter in the end unit lattice go out the area in the zone defined in the spectroscopic data source on Fig. 6 right side by the first boost line 100 and the second boost line 200 to area calculation element 4 according to beginning.
The third situation, when the position of the first boost line and the second boost line overlaps, be comparison means relatively the first abscissa value and the second abscissa value when equating, as shown in Figure 8, the beginning cell that cursor during the calculating of the area of Fig. 8 is distinguished is expert at is identical with the numerical value of end unit lattice, and the area value that area calculation element 4 calculates is 0.
In Fig. 5-Fig. 8, it be for example form that area calculates the district, and first row region representation area is numbered, be read-only, can not edit row; The starting point parameter of " beginning " expression surface area to be measured of secondary series is to edit row; The terminating point parameter of tertial " end " expression surface area to be measured is to edit row; The 4th area that calculate of row " divisor " expression divided by numerical value, be to edit row; The area value in the zone that the 5th row " area " expression is limited by two boost lines, data source and baselines, these row be read-only, can not edit row; The 6th area value that calculate of row " result " expression is divided by the numerical value that the divisor of the 4th row obtains, be read-only, can not edit row.
