Fig. 5 is scale value calculating and adjusts flow chart, and the calculating step of the scale value in the present embodiment is specific as follows：
Step S501, when software starts, initial screen background grid is shown and horizontal, vertical scale value is shown, is set
The current channel number of acquiescence.
Step S502, judges whether the horizontally disposed of oscillograph changes, and whether detection user is grasped by mouse and keyboard
Make the horizontal gear of oscillograph and position setting, if horizontally disposed change, perform step S503, otherwise perform step
S602 detections are vertically arranged variation.
After confirming that scope horizontal setting changes, step S503 sends horizontal gear by host computer to oscillograph
With horizontal position querying command, horizontal gear and horizontal position information are obtained.
The grid set when step S504 is according to software initialization shows to obtain horizontal grid number.
The horizontal grid number that horizontal gear, location information and the step S504 that step S505 is obtained according to step S503 are obtained
The minimum and maximum scale value in calculated level direction illustrates specific algorithm here：Assuming that the dead-center position of horizontal direction exists
Center Screen, by horizontal grid number divided by 2, multiplied by with horizontal gear value, you can obtain it is horizontal when not deviating, it is minimum and maximum
Horizontal scale value, absolute value is equal, respectively positive negative, if level is offset, i.e., horizontal position value is not 0, then will be maximum
Scale value adds horizontal position value, obtains new horizontal scale maximum value；By minimum scale value plus horizontal position value, obtain new
Horizontal scale minimum value.
The horizontal scale minimum value that step S506 obtains step S505, the horizontal gear obtained successively plus step S503
Value, you can obtain the corresponding scale value of all grids of horizontal direction.
After confirming that scope horizontal setting does not change, step S602 is performed, judges being vertically arranged for oscillograph
Whether change, whether detection user is set by the vertical gear of operation with mouse and keyboard oscillograph and position, if vertically setting
It puts and changes, then perform step S603, otherwise cycle performs the setting variation of step S502 detection levels.
Step S603, query steps S602 are vertically arranged changed channel number.
Step S604 specifies the vertical shelves of channel number (being obtained by step S603) by host computer to oscillograph transmission
Position and position enquiring order, obtain vertical gear and location information.
The grid set when step S605 is according to software initialization shows to obtain vertical grid number.
The vertical grid number that vertical gear, location information and the step S605 that step S606 is obtained according to step S604 are obtained
The minimum and maximum scale value of vertical direction is calculated, specific algorithm is similar with horizontal scale：Assuming that the dead-center position of vertical direction
In center Screen, by vertical grid number divided by 2, multiplied by with vertical gear value, you can maximum and most when obtaining not deviating vertically
Small vertical scale value, absolute value is equal, respectively positive negative, if vertically offsetting, i.e., vertical position value is not 0, then will most
High range value subtracts vertical position value, obtains new vertical scale maximum value；Minimum scale value is subtracted into vertical position value, is obtained
New vertical scale minimum value.
The vertical scale minimum value that step S607 obtains step S606, the vertical gear obtained successively plus step S604
Value, you can obtain the corresponding scale value of all grids of vertical direction.
With the obtained channel numbers of step S603 it is corresponding in the vertical scale value that step S607 is obtained, in step S608
Judge whether the channel number of current vertical scale is equal to the channel number that step S603 is obtained,
It is if equal：Step S609 is performed, update vertical scale value is shown；
If differ：Step S610 is performed, recording channel numbers corresponding vertical scale value, does not update scale value and shows.
Above step can be realized modification it is vertical, horizontally disposed when, vertical, horizontal scale value synchronized update.
In the embodiment of the present invention, oscillograph usually has multiple channels, the gear and position that each channel has oneself independent
Setting, therefore the vertical scale value of host computer has multigroup, in order to avoid display is chaotic, host computer only shows the vertical of current channel
Scale value.When user's switching channel, vertical scale value changes synchronous, and the setting with current channel is consistent.User can
With by a variety of method switching channels, such as by clicking right mouse button on host computer waveform display screen curtain or in scale value,
Software pops up channel number menu, and user's click-through number completes the switching of current channel, and software will be performed shown in Fig. 5 at this time
Flow chart, complete vertical scale value calculating and adjustment.
The scale value of host computer is calculated according to the setting of vertical, the horizontal gear of oscillograph and screen raster number
, the screen raster number of host computer and oscillograph slave computer is completely the same, therefore the horizontal scale value of host computer is with showing
The horizontally disposed one-to-one correspondence of wave device, user on host computer or oscillograph when adjusting horizontally disposed, the horizontal scale of host computer
It can synchronized update.The similary vertical scale value of host computer and the oscillograph of corresponding channel are vertically arranged one-to-one correspondence, and user is upper
When being vertically arranged of related channel program is adjusted on position machine or oscillograph, the vertical scale of host computer can synchronized update.When user switches
During current channel, the vertical scale value and color of host computer are by synchronized update.
In conclusion the change of host computer scale value be software according to the level of oscillograph, be vertically arranged with it is currently selected
What channel was automatically performed, user changes the horizontal and vertical setting of oscillograph or switching current channel, will change scale value indirectly
