Fig. 4 is the diagram of circuit of the embodiment one of car alarming display control method provided by the invention, consults Fig. 4, and car alarming display control method comprises the following steps:
Step 40, display control module 1 Real-time Collection car load signal, and judge whether the signal that breaks down, when break down signal time, perform next step, otherwise, continue to perform this step;
Whether the kind of step 41, display control module 1 failure judgement signal, priority level and this breakdown signal have shown corresponding picture or icon, selected priority level is the highest and shown the breakdown signal of corresponding picture or icon, and sends corresponding alarm message instruction according to the kind of this selected breakdown signal to driver module 3;
Step 42, driver module 3 receive and the alarm message instruction sent according to display control module 1, the picture region 5 of corresponding picture time display display module 4 is transferred from memory module 2, after setting-up time arrives, control display module 4 by driver module 3 to stop Showing Picture, and transfer from memory module 2 icon frame 61 that corresponding icon is presented at an idle condition display module 4 simultaneously;
Whether step 43, display control module 1 failure judgement signal are removed, and if so, perform next step, otherwise continue to perform this step;
Step 44, driver module 3 control display module 4 to be stopped showing picture corresponding to this breakdown signal or icon;
Whether step 45, the picture region 5 judging display module 4 are idle condition, perform step 40 if return, no this step of continuations execution.
The kind of the breakdown signal mentioned in above-mentioned steps 41, priority level and this breakdown signal whether have shown corresponding picture or icon refers to display control module 1 in advance to the relevant parameter of each breakdown signal setting, and by this parameter stored in display control module 1, therefore, display control module 1 can by checking the species parameter of breakdown signal, whether priority level parameter and this breakdown signal be and show corresponding picture or icon parameter, and selected priority level is the highest and shown the breakdown signal of corresponding picture or icon, and send corresponding alarm message instruction according to the kind of this selected breakdown signal to driver module 3.
Transfer from memory module 2 icon frame 61 that corresponding icon is presented at an idle condition display module 4 in above-mentioned steps 42 to be realized by following two schemes, the first is, icon random display is at the icon frame 61 of any one idle condition, the second is, from left to right or from right to left judge in icon area 5, whether each icon frame 61 is idle condition successively, when some icon frames 61 are idle condition, transfer corresponding icon from memory module 2 and be presented at this icon frame 61 icon area 6, then continue to perform step 43, otherwise continue to perform this step.
As the further preferred version of the present embodiment, in step 42, be preset with flicker frequency in described display control module 1, this display control module 1, according to flicker frequency, controls display module 4 by driver module 3 and the picture of display in picture region 5 is shown in the mode of timing flicker.It should be noted that at this, the concrete value of its flicker frequency can be set arbitrarily according to required flicker effect by designer.
As the present embodiment and or the further preferred version of above preferred embodiment, driver module 3 controls display module 4 and stops Showing Picture and to be realized by following steps in step 42:
Benchmark transparence value is preset with in described display control module 1, after setting-up time arrives, display control module 1 controls display module 4 with benchmark transparence value for starting point by driver module 3, progressively increase the transparence value of the picture of display in picture region 5, when transparence value reaches 100%, display module 4 stops Showing Picture.
It should be noted that at this, the parameters such as the transparence value of said reference transparence value, increase, can be set according to actual required effect by designer, not elaborate at this.
Fig. 5 is the diagram of circuit of the embodiment two of car alarming display control method provided by the invention, consults Fig. 5, and car alarming display control method comprises the following steps:
Step 50, display control module 1 Real-time Collection car load signal, and judge whether the signal that breaks down, when break down signal time, perform next step, otherwise, continue to perform this step;
Whether the kind of step 51, display control module 1 failure judgement signal, priority level and this breakdown signal be and show corresponding picture or icon, selected priority level is the highest and shown the breakdown signal of corresponding picture or icon, and sends corresponding alarm message instruction according to the kind of this selected breakdown signal to driver module 3; Display control module 1 sends the flicker frequency (as 1HZ) and benchmark transparence value (30%) preset to driver module 3 simultaneously;
Step 52, driver module 3 receive and the alarm message instruction sent according to display control module 1, flicker frequency (as 1HZ) and benchmark transparence value (30%), transfer corresponding picture from memory module 2, regularly flickering display picture;
Step 53, display control module 1 judge whether picture displaying time reaches Preset Time (as 4S), when reaching, performs next step, otherwise continue to perform step 52;
Step 54, display control module 1 control display module 4 with benchmark transparence value (30%) for starting point by driver module 3, progressively increase the transparence value of the picture of display in picture region 5, when transparence value reaches 100%, display module 4 stops Showing Picture, and transfer corresponding icon from memory module 2, be presented at an icon frame 61 of idle condition in display module 4;
Whether step 55, display control module 1 failure judgement signal are removed, if then perform next step, otherwise continue to perform this step;
Step 56, display control module 1 control display module 4 by driver module 3 and stop display removing picture corresponding to the breakdown signal of fault and/or icon;
Step 57, display control module 1 judge whether the picture region 5 of display module 4 is idle condition, perform step 50, otherwise continue this step if return.
The present embodiment is identical with a upper embodiment (car alarming display control method) major part, difference is only, in the present embodiment, display control module 1 is preset with flicker frequency and benchmark transparence value, thus control display module 4 timing flickering display picture by driver module 3, and after arriving until setting-up time, the transparence value of the picture of display increases gradually, thus make the picture shown become transparent gradually until disappear, namely picture display stops, and at icon frame 61 display icon while picture disappears, like this, the content of alarm display of the present invention can be made abundanter, have more innervation, therefore the attention of chaufeur is more easily caused.
In the above-described embodiments, the image content that picture region 5 shows can be word, letter, pattern etc., but the content that can preferably show is word, such as when the word of picture display is " leakage of oil ", " oil mass is low; please add fuel oil ", " water temperature is high ", " safety strap system " etc., it is any breakdown signal that chaufeur just can easily be learnt, and what do not need memoriter to judge the picture prompting shown is any breakdown signal, thus brings more convenience to chaufeur.In addition, the iconic content that in display module 4, icon area 6 shows also can be Word message, pattern or sign flag etc.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
