Abstract
The invention provides a display system rotating method based on an Android digital label system. The display system rotating method comprises the following steps: S1, selecting a system rotating angle; S2, updating a database and saving rotating angle data; S3, updating the rotating angle attribute of the system; S4, selecting restarting; S5, restarting the system. The display system rotating method has the benefits that variation in a horizontal direction does not need to be monitored by a sensor in equipment, and rotating setting can be carried out on the display system of the digital label system in a fixed mounting position.
Description
Technical field
The present invention relates to display system spinning solution, particularly relate to a kind of display system spinning solution based on Android digital signage system.
Background technology
Based on handheld devices such as the mobile phone of android system or flat boards, user is by handheld device and changes different directions, is carried out the change in level monitoring direction by device interior inductor, thus the different directions of adjustment display system.And most of digital signage system is fixed installation position, admittedly cannot be monitored by internal inductor.
Summary of the invention
In order to solve the problems of the prior art, the invention provides one.
The invention provides a kind of display system spinning solution based on Android digital signage system, comprise the following steps:
S1, the selective system anglec of rotation;
S2, more new database, preserve pivoting angle data;
S3, renewal system anglec of rotation attribute;
S4, selection are restarted;
S5, system reboot.
As a further improvement on the present invention, further comprising the steps of:
S6, kernel and drive load start;
S7, Android Init process initiation;
S8, reading system anglec of rotation attribute;
S9, loading start up graphic corresponding to attribute.
As a further improvement on the present invention, further comprising the steps of:
Other kernel services of S10, system start;
S11, system core window display service starts;
S12, function reading system anglec of rotation attribute, upgrade the direction of display system and lock.
As a further improvement on the present invention, further comprising the steps of:
S13, continuation start other services;
S14, Android have started.
The invention has the beneficial effects as follows: by such scheme, do not need the change being come level monitoring direction by device interior inductor, rotary setting can be carried out to the display system of the digital signage system of fixed installation position.
Accompanying drawing explanation
Fig. 1 is the process flow diagram of a kind of display system spinning solution based on Android digital signage system of the present invention;
Fig. 2 is the Booting sequence figure of a kind of display system spinning solution based on Android digital signage system of the present invention.
Embodiment
Illustrate below in conjunction with accompanying drawing and embodiment the present invention is further described.
As shown in Figure 1 to Figure 2, a kind of display system spinning solution based on Android digital signage system, comprises the following steps:
S1, the selective system anglec of rotation;
S2, more new database, preserve pivoting angle data;
S3, renewal system anglec of rotation attribute;
S4, selection are restarted;
S5, system reboot.
S6, kernel and drive load start;
S7, Android Init process initiation;
S8, reading system anglec of rotation attribute;
S9, loading start up graphic corresponding to attribute.
Other kernel services of S10, system start;
S11, system core window display service starts;
S12, function reading system anglec of rotation attribute, upgrade the direction of display system and lock.
S13, continuation start other services;
S14, Android have started.
Android system is in start-up course, the stage is drawn at the window of whole system, system drafting is carried out in the direction giving tacit consent to a level, the present invention imports newly-increased bearing mark parameter in the window drafting stage of android system, the direction that system carries out display system according to this parameter is drawn, thus the function that the system that reaches rotates.
In " display is arranged " of " Operation system setting " page, increase the setting option of " system rotation " newly, and the rotation of 4 angles is provided: 0 degree, 90 degree, 180 degree, 270 degree (being defaulted as 0 degree).User or operating personnel select the angle needing to rotate, will be kept at after selection in android system database, data will trigger a this programme new property value (persist.sys.system_rotation) after preserving renewal in a database upgrades, after renewal, will eject a menu prompt user restarting equipment, equipment will rotate after restarting in completion system display.
The newly-increased system property value (persist.sys.system_rotation) of the present invention, as the important parameter of system rotation process in start-up course, increases the anglec of rotation arranged in menu that a record carrys out simultaneous user simultaneously in android system database.Time Android startup enters Logo drafting, read the system property value that this programme is newly-increased, according to this property value, be loaded into the Logo picture of the different directions pre-stored, thus reach the system boot Logo of different display directions, when Android start up system is in the process of start up system core window services (WindowsMangerService), updateRotationUncheckeLocked method will read the direction that this attribute (persist.sys.system_rotation) revises current display system, and lock this direction, thus the rotation of completion system display.
Before improvement, need the system firmware compiling different angles, for the system firmware that distinct device burning is different, different firmware can not be general.
After improvement, increase newly and menu has been set, very big handled easily, and the system estimation that all devices only needs burning identical, greatly provide the efficiency generating and construct, also avoid the system firmware of burning wrong version simultaneously.
A kind of display system spinning solution based on Android digital signage system provided by the invention, be applicable to any digital signage system based on android system, the method of display system rotary setting is provided, be also applicable to simultaneously based on Android platform etc. need equipment that display frame is rotated.Use this method to spend by rotary system to 0 easily, 90 degree, 180 degree, 270 degree, greatly facilitate various digital signage system application scenario, bring great convenience.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
