As shown in fig. 1, an embodiment of the present application provides an image display method of an air quality condition, including:
and S10, receiving parameter setting information.
The parameter setting information includes a start time, an end time, a time axis type, a picture display speed, and the like.
And receiving parameter setting information such as start time, end time, time axis type, picture display speed and the like input by a user through an input end. For example, a start time of 1 month and 1 day of 2020, an end time of 1 month and 20 days of 2020, a time axis type day type time axis are input; or the starting time of 2020, 1 month, 1 day and 0 hour and the ending time of 2020, 1 month, 1 day and 20 hours are input.
The time axis types include an hour type time axis (shown in fig. 2), a day type time axis (shown in fig. 3), and a month type time axis, etc. The minimum scale unit on the hour type time axis is hour, the minimum scale unit on the day type time axis is day, and the minimum scale unit on the month type time axis is month.
The picture display speed may be set, for example, to 3 seconds or 5 seconds after each picture is displayed, and then the next picture is displayed, and the pictures are played in a loop. The picture display speed can be set according to actual needs.
And S20, setting a time axis according to the parameter setting information.
In some embodiments, the start time is used as the start time of the time axis, the end time is used as the end time of the time axis, the minimum scale unit of the time axis is determined according to the type of the time axis, and the scale values on the time axis and the time axis are formed.
In some embodiments, setting the time axis according to the parameter setting information includes:
1) and setting a time axis starting point and a time axis end point according to the starting time and the ending time.
Specifically, the start time and the end time may be converted into millisecond values, respectively, and the time axis start point and the time axis end point may be calculated by a time calculation method.
2) And determining the minimum scale unit of the time axis according to the time axis type.
For example, the minimum scale unit of the day type timeline is days, the minimum scale unit of the hour type timeline is hours, and the minimum scale unit of the month type timeline is months.
3) And determining the scale value on the time axis according to the time axis starting point, the time axis end point and the time axis minimum scale unit.
The start time is used as a time axis starting point, the end time is used as a time axis end point, time axis scale values are arranged at equal distances between the time axis starting point and the time axis end point, and a minimum scale unit is arranged between every two adjacent scale values.
For example, according to parameters such as the start time, the end time, the time axis type and the like input by a user through an input end, millisecond values of the start time and the end time are respectively calculated; calculating the millisecond value of the starting time and the millisecond value of the ending time by taking 1 month, 1 day and 0 day of 1970 as a time origin; millisecond values are values in milliseconds; for example, with 1970, 1/0 as the time origin, the millisecond value at 1970, 2/11/0 was 41 × 24 × 60 × 60 × 1000 milliseconds; the advantage of using millisecond values to represent time is that various inconveniences caused by switching in time representation due to different days of each month are avoided;
calculating the time difference between the ending time and the starting time, and converting the time difference into a millisecond value;
according to the time axis type, superposing the corresponding time difference expressed by the millisecond value on the millisecond value of the starting time to obtain the millisecond value of the ending time, and converting the superposed millisecond value of the ending time into the coordinated universal time; the time format may be converted differently depending on the different timeline types.
For example, if the hour-type timeline is selected, the millisecond value at the start time is superimposed 3600000 milliseconds each time, the superimposed value is converted back to UTC time, and the time format is adjusted according to the different timeline types. The conversion algorithm of the millisecond value and the UTC time is realized by using a tool class carried by JavaScript. The UTC time is also called universal time, and international coordinated time.
The input end comprises a mouse and a keyboard. The data of any time point which is wanted to be seen can be clicked through a mouse to click on the previous button control, the next button control and the automatic playing button control, or click on the time point on the time axis to select. The time can also be switched and selected according to the operation of the keyboard keys (default up and down direction keys).
The user can also select different playing speeds, and the data viewing effect can be dynamically inquired according to the current playing speed during automatic playing. The method mainly comprises the steps of continuously switching the currently selected time through the change of the playing speed, and changing the displayed result data according to the change of the selected time.
And S30, selecting the air quality condition pictures corresponding to the scale values of the time axis from the database, and respectively associating the air quality condition pictures with the corresponding scale values.
Specifically, time parameters of all air quality condition pictures in a database are inquired, the air quality condition picture to be displayed is selected, the air quality condition picture to be displayed is the air quality condition picture with the time parameter corresponding to the scale value on the time axis, and then the selected time parameter of the air quality condition picture to be displayed is associated with the scale value of the time axis respectively, so that the association between the air quality condition picture to be displayed and the scale value of the time axis is realized.
Generally, each minimum scale unit on the time axis corresponds to one air quality condition picture. The scale value is consistent with the time parameter of the air quality condition picture. For example, each scale unit on the day type time axis is one day, and the time parameter of the air quality condition picture corresponding to the scale value of 5, 1 and 5 in 2020 is also 5, 1 and 2020. The time parameter corresponds to the scale value, i.e. both represent the same time. The type of the time parameter of the air quality condition picture corresponds to the type of the minimum scale unit, for example, if the minimum scale unit is one day, the time parameter of the air quality condition picture associated with each minimum scale unit is also one day, that is, the air quality condition picture shows the air quality condition of a certain day; if the minimum scale unit is one hour, the time parameter of the air quality condition picture associated with each minimum scale unit is also one hour, that is, the air quality condition picture shows the air quality condition of one hour on a certain day. The air quality condition pictures comprise a picture with a time parameter of day, a picture with a time parameter of hour and the like, the picture with the time parameter of day reflects the air quality condition of one day, and the picture with the time parameter of hour reflects the air quality condition of one hour on a certain day. When the minimum scale unit on the time axis is day, a picture with a time parameter of day can be correspondingly associated with each minimum scale unit; when the minimum scale unit on the time axis is hour, a picture with hour time parameter may be associated with each minimum scale unit. In this way, it is possible to display an associated air quality situation picture every time a minimum scale unit passes along the time axis.
And S40, sequentially displaying all the air quality condition pictures related to the scale value of the time axis at the set picture display speed along the time axis.
As shown in fig. 4, all the air quality status pictures are sequentially played in a circulating manner according to the set picture display speed and the time parameter sequence. The time parameter sequence is the same as the scale value arrangement sequence of the time axis. All the air quality condition pictures in the time period between the starting time and the ending time correspond to the scale values on the time axis according to the time parameters of all the air quality condition pictures. For example, if the time parameter of an air quality condition picture is 1, 3 and 2020, the time parameter of the air quality condition picture corresponds to and is correlated with the scale value of 1, 3 and 2020 on the time axis, and the time parameter of 1, 3 and 2020 represents that the air quality condition picture shows the air quality condition of 1, 3 and 2020. The time parameter of the air quality condition picture represents the time of the air quality condition displayed by the air quality condition picture.
The air quality condition picture may include a plurality of parameter values, such as a geographical location parameter, a time parameter, and the like. The geographic location parameter may be a province, a country, etc., and the time parameter may be a certain day of a month, a certain time of a certain day of a month, etc. All that is required to correlate with the scale values on the time axis is the time parameter.
S50, when all the air quality condition pictures related to the scale values of the time axis are sequentially displayed, detecting whether a pause signal and a continuous display signal are received in real time;
and when the pause signal is received, keeping the currently displayed air quality condition picture in a display state, and not displaying the next air quality condition picture until the continuation of the display signal is detected, and then continuing to sequentially display the following air quality condition pictures.
When a worker watches the sequential display of the air quality condition pictures, if one of the air quality condition pictures needs to be observed for a long time, a pause signal is input through an input end such as a mouse or a keyboard, the air quality condition picture is paused in a display state, and when the air quality condition pictures need to be continuously displayed, the worker inputs a continuous display signal through the input end to continuously and sequentially display the following air quality condition pictures.
As shown in fig. 5, another embodiment of the present application provides an image display device of an air quality status, including:
the interactive module 10 is used for receiving parameter setting information; the interaction module can comprise a touch display screen, various parameter setting options are displayed on the touch display screen, and a user inputs parameter setting information on the touch display screen;
