The unit time length is a constant value time length set by a worker, the height value corresponding to the variable height information is a difference value between the heights corresponding to the two display height information in sequence in the unit time length, and the difference value is an absolute value.
Step S501: and judging whether the height value corresponding to the change height information is smaller than a preset micro-change value or not.
The micro-change value is the maximum value of the display height which is recognized by the staff and does not have obvious change, and the purpose of judgment is to know whether the display height has obvious change or not so as to be convenient for adjusting the position of important monitoring information.
Step S5011: and if the height value corresponding to the height information is smaller than the micro-variation value, controlling important monitoring information to be displayed at the original height.
When the height value corresponding to the height information is smaller than the micro-variation value, the display height is indicated to be unchanged obviously, and the important monitoring information is controlled to be displayed at the original display height at the moment, so that the important monitoring information is reduced to be continuously subjected to fine adjustment in the height direction, and the user can observe conveniently.
Step S5012: and if the height value corresponding to the change height information is not smaller than the micro change value, outputting an adjusting signal and controlling important monitoring information to be displayed on the current display height information.
When the height value corresponding to the height information is not smaller than the micro-variation value, the display height is indicated to have obvious variation at the moment, in order to facilitate the user to observe the information, important monitoring information is controlled to be displayed on the current display height information, and meanwhile, an adjusting signal is output to mark the condition, so that the follow-up control of the display position is facilitated.
Referring to fig. 8, the important monitoring information display position adjustment method further includes:
step S600: and defining a detection interval with a time range of a preset fixed duration on a preset positive sequence time axis, and controlling the rear end point of the detection interval to synchronously move along with time.
The positive sequence time axis is an axis formed by time points along the time passing direction, the fixed time length is a fixed value set by a worker, the detection interval is an interval with the time range of the positive sequence time axis being the fixed time length, and the detection interval synchronously moves along with the time so as to be convenient for collecting, acquiring and analyzing the latest data.
Step S601: and judging whether an adjusting signal exists in the detection interval when the height value corresponding to the change height information is not smaller than the micro-change value.
When the height value corresponding to the height information is not smaller than the micro-variation value, the display height is indicated to have obvious variation, and the purpose of judgment is to know whether the position of the important monitoring information is adjusted within a fixed time length.
Step S6011: and if the height value corresponding to the change height information is not smaller than the micro change value, outputting an adjusting signal and controlling important monitoring information to be displayed on the current display height information.
When the height value corresponding to the change height information is not smaller than the micro change value, the fact that the adjustment signal does not exist in the detection section indicates that the position of the important monitoring information is not adjusted within a fixed duration, and the adjustment signal is normally output to adjust the position of the important monitoring information.
Step S6012: if the height value corresponding to the change height information is not smaller than the micro change value, an adjusting signal exists in the detection section, the adjusting signal is not output, and the important monitoring information is controlled to be displayed at the original height.
When the height value corresponding to the change height information is not smaller than the micro-change value, the position of the important monitoring information is adjusted in a fixed time period when the adjustment signal exists in the detection interval, and the change height information is larger, which is possibly caused by accidental users, and the adjustment signal is not output and the important monitoring information is maintained to be displayed in the original position, so that the overall adjustment frequency of the important monitoring information is reduced, and the observation of staff is facilitated.
Referring to fig. 9, when the important monitoring information is displayed at the height corresponding to the display height information, the important monitoring information display position adjustment method further includes:
step S700: and acquiring fixed point position information of front and rear positioning devices preset on the helmet.
The positioning equipment on the helmet is the same as the positioning equipment on the shoes and is used for acquiring corresponding point positions, the front and rear positions on the helmet are the front endpoint and the last endpoint when the helmet is correctly worn, and the positions corresponding to the fixed point position information are the coordinate positions of the two positioning equipment on an external space coordinate system.
Step S701: and connecting lines according to the two fixed point position information to determine orientation straight line information, and determining intersection point position information of the plane with the main visual angle display according to the orientation straight line information.
The straight line corresponding to the orientation straight line information is a straight line formed by connecting the positions corresponding to the two fixed point position information, the main sight line of the user is positioned on the straight line, the position corresponding to the intersection point position information is the position of the main observation point of the main sight line of the user on the plane of the main line foot display, and the main sight line is determined by a method that the straight line corresponding to the orientation straight line information intersects with the plane.
Step S702: and judging whether the position corresponding to the intersection point position information is in the main visual angle display.
The purpose of the determination is to know whether the user's primary line of sight is within the primary viewing angle display.
Step S7021: and if the position corresponding to the intersection point position information is not in the main visual angle display, controlling important monitoring information to be displayed in the original position.
When the position corresponding to the intersection point position information is not in the main visual angle display, the user's sight is outside the main visual angle display, the sitting posture of the user is not changed, the user's visual angle change is probably something to be processed by head bias, the time is short, and the position adjustment of important monitoring information is not needed.
Step S7022: if the position corresponding to the intersection point position information is in the main visual angle display, calculating the distance between the intersection point and two sides of the display in the transverse direction to determine transverse interval information, determining smaller interval information in the two transverse interval information, and defining one side of the display corresponding to the smaller interval information as a similar side.
When the position corresponding to the intersection point position information is positioned in the main visual angle display, the user's sight line is described as being positioned in the main visual angle display, and at the moment, the transverse position of the important monitoring information on the display can be adjusted so as to be further convenient for the user to observe; the corresponding position of the transverse interval information is the vertical distance between the observation point of the user on the display of the main visual angle and the transverse sides of the display, the smaller interval information is the transverse interval information with smaller corresponding numerical value in the two transverse interval information, and meanwhile, one side of the display corresponding to the smaller interval information is defined as the near side so as to determine the side, close to the observation point, of the transverse sides on the display, so that the subsequent important monitoring information can be conveniently adjusted on the display.
Step S703: and judging whether the smaller interval information is smaller than half of transverse parameter information.
The purpose of the judgment is to know whether the distance between the observation point and the close side can accommodate half of the important monitoring information, i.e. whether the center point of the important monitoring information can be displayed on the observation point.
Step S7031: and if the smaller interval information is smaller than half of the transverse parameter information, the side, close to the near side, of the frame for controlling the important monitoring information is attached to the near side.
When the smaller interval information is smaller than half of the transverse parameter information, the central point of the important monitoring information cannot be displayed on the observation point, at the moment, one side, close to the near side, of the frame for controlling the important monitoring information is attached to the near side so as to display the important monitoring information on the main visual angle display, and meanwhile, the central point of the important monitoring information is closer to the observation point so that the user can observe the important monitoring information conveniently.
Step S7032: and if the smaller interval information is not less than one half of the transverse parameter information, controlling the preset center point of the important monitoring information to move to the position corresponding to the intersection point position information.
When the smaller interval information is not less than half of the transverse parameter information, the central point of the important monitoring information can be displayed on the observation point, and the central point of the important monitoring information is controlled to move to the position corresponding to the intersection point position information so as to be convenient for a user to observe, wherein the central point of the important monitoring information can be determined according to the frame parameter information, and the conventional technical means of the person skilled in the art are omitted.
