Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flow chart of the electronic guideboard control method based on the working environment of the invention. As shown in fig. 1, the electronic guideboard control method includes the following steps: detecting the working environment temperature of the electronic guideboard; and when the working environment temperature exceeds a certain threshold range, switching the working mode of the electronic guideboard from full-screen display to local display. The working environment temperature can be collected by utilizing a temperature sensor arranged in the electronic guideboard, and the temperature threshold range can be artificially set, such as: may be set at 30 c, may be set at 25 c, etc. When the collected temperature is below the threshold value, the display screen of the electronic guideboard works normally; and when the collected temperature exceeds the threshold value, the display screen of the electronic guideboard is protected by switching the display mode of the electronic guideboard.
Example 1
Fig. 2 is a schematic diagram illustrating the embodiment of the invention switching to a partial display. Fig. 2 shows that the working area of the electronic guideboard is reduced by closing part of the display area of the electronic guideboard display screen when the ambient temperature exceeds the threshold range. As in the case of the content previously displayed full screen, it is displayed only in a partial area of the display screen. The size of the display area can be set arbitrarily, for example, the display area can be an area for displaying 2 words, or an area for displaying 5 words, and meanwhile, in order not to affect the integrity of the display content, the display content can be displayed in a scrolling manner in the display area.
FIG. 3 is a flow chart of a method for performing partial display according to an embodiment of the present invention. Each display unit of the electronic guideboard is coded, each display unit is an LED, and M, N of the display units can be rows and columns where the LEDs are located in the display screen according to the position coordinates (1, 1), (1, 2) and … … (M, N) of the display units in the display screen.
The electronic guideboard is subjected to display testing by adopting a sample library, wherein the sample library is characters and patterns which are usually displayed by the electronic guideboard, for example, 307 buses are going to stop after 5 minutes, the temperature of the current day is 5-15 ℃, the tail number of the current limit is 0 and 9, and the like, the electronic guideboard is tested by utilizing the characters and the patterns in the sample library, whether each display unit displays the current guideboard is counted and displayed, and the total display times are calculated; specific examples are given in the following table:
similarly, statistics are performed on each display unit as described above to obtain the total display times of each display unit. The display time threshold is set, for example, for an electronic stop board with 5 display samples, the display time threshold may be set to be 2 or 3, and all display unit numbers higher than the display time are counted.
And when the ambient temperature is detected to be higher than a certain threshold value, if the ambient temperature is higher than 30 ℃, closing all the display units higher than the display frequency threshold value, and only allowing the display units with the display frequency lower than the display frequency threshold value to work so as to prolong the service life of the whole electronic stop board.
Scanning the rest display units, selecting continuous positions, and forming a rectangular display area, wherein the area of the rectangular area can be represented as K x L, and K and L respectively represent the number of the display units and are positive integers; the blocks that can constitute the rectangular display area are stored and numbered.
According to the environment temperature, selecting the area and the number of the display areas, if the temperature exceeds a threshold value, not much, if the threshold value is 30 ℃, and when the current temperature is 30-35 ℃, selecting a single display area with relatively large area and the number of the display areas which can be 1 or more; if the temperature exceeds the threshold value more, if the current temperature is 36 ℃ -40 ℃, namely the ambient temperature is higher, in order to prevent the display unit from being damaged by high temperature, the area of a single display area can be selected to be smaller, and the number of the blocks can be 1 or more. And according to the measured environment temperature, setting a preset area rectangular region, further selecting a display unit capable of forming the preset area rectangular region to perform local display, wherein the display content can be played in a rolling manner in the local display region, and if the occupied area of the display content is smaller than the area of the display region, the display content can also be played in a fixed manner without rolling.
Fig. 4 is a schematic view showing that the display screen of the first embodiment of the present invention is rotatable. Fig. 4-1 and 4-2 show schematic views of rotatable display screens, respectively. The rotation speed of the display screen can be set to match the scrolling speed of the content, for example, for a user in a certain direction, the user currently sees a first part of the displayed content, after the display screen rotates for one circle, the displayed content exactly scrolls to a second part, the second part is connected with the first part, and the like. The display screen is convenient for users in multiple directions around the electronic stop board to obtain the display content, and the display content can not be missed by the users in a certain direction due to the rotation of the display screen. The display screen of electron signpost can be that the polylith square display screen evenly arranges around the support component, also can be annular display screen.
Example 2
The second embodiment of the present invention provides a technical solution for closing the current display screen and playing the current display content by using a speaker when the ambient temperature exceeds a higher temperature threshold, such as above 40 ℃, that is, the ambient temperature is close to or exceeds the rated operating temperature of the display unit, or when the remaining display units cannot form a rectangular display area with a preset area; the display form of the content is completely changed, the display is changed into the voice prompt, the user is not influenced to obtain the content, and the protection of the display screen of the electronic guideboard under the ultrahigh temperature is realized.
