Abstract
The invention particularly relates to a handset screen turning off and awakening method based on a ReWorks system. The handset screen turning off and awakening method based on the ReWorks system comprises the steps that a function is defined in a driver of the ReWorks operating system, meanwhile, an OS_Event_31 signal is adopted as a screen awakening signal, then a new screen management task is established, and the procedure of turning off and on a screen is achieved by monitoring the OS_Event_31 signal. According to the handset screen turning off and awakening method based on the ReWorks system, aiming at application of the domestic ReWorks real-time operating system to a handset, the screen can be turned off in time in an idle state to save the electric quantity, the screen is fast turned on when needed, and therefore power consumption speed is reduced, the use duration of the handset is prolonged, and then the functions of protecting a battery of the handset and prolonging the service life of the handset are achieved.
Description
Technical field
The present invention relates to embedded software system technical field, realize, particularly to a kind of hand-held set based on ReWorks system, the method that screen is closed and waken up.
Background technology
Along with the propelling of the ripe and domestic substitution plan of homemade software and hardware product, homemade software and hardware product is increasingly widely applied in domestic communication equipment and Defense Information equipment.
China is information-based proposes great demand with all-round well-off society's construction to embedded system market, Internet appliance product annual requirement several hundred million, each class digitized household appliances have ten million platform market demand, industrial controlling embedded system has a hundred or so ten thousand set demands, commercial embedded system demand millions of.China has integrated circuit and pulls the production in enormous quantities ability of grade product, and the Embedded Application product of outlet also will progressively increase, and also can occupy a tiny space in world market.
Under such market environment, the embedded real-time operating system Reworks of the independent intellectual property right that Huadong Computing Technology Inst. releases necessarily has broad application prospects.This system has been successfully applied to the project such as ship electronic, vehicle mounted guidance.
Owing to hand-held set is that battery is powered, electricity is limited, and screen is a power consumption rich and influential family, in order to extend the use duration of hand-held set as far as possible, it is necessary to close screen at one's leisure to save electricity, and use time point bright screen curtain at needs.
Based on this, the present invention devises a kind of hand-held set based on ReWorks system and realizes the method that screen is closed and waken up.
Summary of the invention
The present invention is in order to make up the defect of prior art, it is provided that a kind of simple efficient hand-held set based on ReWorks system realizes the method that screen is closed and waken up.
The present invention is achieved through the following technical solutions:
A kind of hand-held set based on ReWorks system realizes the method that screen is closed and waken up, it is characterised in that comprise the following steps:
First, defining three functions in the driving of ReWorks operating system, respectively close screen backlight function, half closes screen backlight function and opens screen backlight function, for routine call；
Secondly, utilize in ReWorks operating system OS_Event_31 signal as waking screen signal up；
Then, ReWorks operating system is set up a new screen management task, by monitoring OS_Event_31 signal, to realize closing and opening the flow process of screen.
The main logic of described new screen management task is: if receiving OS_Event_31 signal, then calls and opens screen backlight function, described in open the state that screen backlight function makes screen light or is remain on；If exceeding certain time t1 not receive OS_Event_31 signal, then calling half pass screen backlight function, making screen become half bright state；If exceeding certain time t2 in the state that screen half is bright not receive OS_Event_31 signal, calling with closing screen backlight function, making screen blackening.
Described time-out time t1 and t2 can configure.
Keystroke handling interrupt processing function and touch screen in ReWorks operating system process and are separately added into the function sending OS_Event_31 signal to new screen management task in interrupt processing function, in order to make button operation and contact action all can wake screen up.
The invention has the beneficial effects as follows: should realize, based on the hand-held set of ReWorks system, the method that screen is closed and waken up; for the application on the handset of domestic ReWorks real time operating system; screen can be closed at one's leisure in time to save electricity; and screen is lighted rapidly when needs use; thus slow down power consumption rate; extend the use duration of hand-held set, and then play protection cell of mobile telephone set, extend the effect in hand-held set service life.
Accompanying drawing explanation
Accompanying drawing 1 is screen management task status of the present invention transition schematic diagram.
Detailed description of the invention
In order to make the technical problem to be solved, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the present invention will be described in detail.It should be noted that, specific embodiment described herein is only in order to explain the present invention, it is not intended to limit the present invention.
Should realize, based on the hand-held set of ReWorks system, the method that screen is closed and waken up, comprise the following steps:
First, defining three functions in the driving of ReWorks operating system, respectively close screen backlight function, half closes screen backlight function and opens screen backlight function, for routine call；
Secondly, utilize in ReWorks operating system OS_Event_31 signal as waking screen signal up；
Then, ReWorks operating system is set up a new screen management task, by monitoring OS_Event_31 signal, to realize closing and opening the flow process of screen.
The main logic of described new screen management task is: if receiving OS_Event_31 signal, then calls and opens screen backlight function, described in open the state that screen backlight function makes screen light or is remain on；If exceeding certain time t1 not receive OS_Event_31 signal, then calling half pass screen backlight function, making screen become half bright state；If exceeding certain time t2 in the state that screen half is bright not receive OS_Event_31 signal, calling with closing screen backlight function, making screen blackening.
Described time-out time t1 and t2 can configure.
Keystroke handling interrupt processing function and touch screen in ReWorks operating system process and are separately added into the function sending OS_Event_31 signal to new screen management task in interrupt processing function, in order to make button operation and contact action all can wake screen up.
The flow process that screen closes should be realized as follows based on the hand-held set of ReWorks system:
(1) screen management task time-out does not receive screen wake-up signal；
(2) backlight function is closed in screen management task call half, makes screen dimmed；
(3) screen management task again time out does not receive screen wake-up signal；
(4) backlight function is closed in screen management task call, makes screen close.
The flow process that screen wakes up should be realized as follows based on the hand-held set of ReWorks system:
(1) button or touch operation trigger screen wake-up signal；
(2) screen management task receives screen wake-up signal；
(3) backlight function is opened in screen management task call, lights screen.
The method that screen is closed and waken up should be realized based on the hand-held set of ReWorks system; for the application on the handset of domestic ReWorks real time operating system; screen can be closed at one's leisure in time to save electricity; and screen is lighted rapidly when needs use; thus slow down power consumption rate; extend the use duration of hand-held set, and then play protection cell of mobile telephone set, extend the effect in hand-held set service life.
